Best iPhone Battery Backup

Here we are, in our world of technology.  Toaster ovens, DVRs, Blue Ray, Portable game units, Laptops, Smart phones and our iDevices.  All these things use energy.  Aside from Air, Water and Food…It is the most needed commodity we, as people are most addicted to.  It is the central source, the origin of literally all our creature comforts, conveniences and society.  It also happens to be the most precious and demanded resource we use.

Our iPhones are no different.  Our precious iDevices are amazing in their versatility, capacity and function.  There is just one small problem with them.  As good as they are the power they deliver is too much for any real heavy use on the battery they come equipped with.  The very battery that supplies our toy with the power to run.  No power, no function.  No function no fun.  No ticky, no shirty…You get the point.

The iPhone battery is nominally functional and with any degree of heavy use, will find you with a “brick”.  My Girlfriend, knowing I could use something like this, for the holidays surprised me with a little gift.  It was a Duracell backup battery.  It cost her $30.  It sucked, to say the least.  While finely crafted, it offered a measly 1 time charge and only then would charge my iPhone 50%.  I was extremely appreciative of her thought but let’s be honest her between us, that just will not cut it for our uses.  Hence the need for a back up.  In my search for such an item I scoured the web looking for a quality unit that would perform exemplary but at a reasonable price.  I looked at Richard Solo.  I looked at iSound.  I looked at them all.  Prices, capacity, function…But then I stumbled completely on one completely by accident from a company called “iMaxPower” and one particular product called TheIMP500.

Here is what caught my attention in the listing in my search “38 hour video play back“.   When I saw this in combination with their reasonable price of $53.95 I was hooked to find out more.  So I do what I always do for myself and my readers.  I investigated.  Therein (as you will see in the site) is a 10 min Video with the head of the company demonstrating the IMP500, John Chang.  In there he explains and shows how to use the IMP500.  I was very interested in this product and decided to contact iMpaxPower and Mr. Chang.  After an email and a follow up call, Mr. Chang immediately sent me an IMP500 to test, review and now you will get to know everything that you need to know about this product and the company that builds it.  So hang on kids cause here we go!

First off, delivery of the item (BTW shipping is free for orders over $30) arrived no later than 3 days.  Yes three days!  That in itself is good, damned good.  The packaging is a typical hermetically  sealed blister package.  Removal of the items are simply done with a sharp knife or razor blade along the sides.  But aside from this, who really cares about the packaging?  It is a marketing device which holds absolutely no merit to the form and function of this review.  Personally I would not care if any item I got came in a wet paper bag with a Tuna Fish Sandwich and a Banana inside.  Once we get our items home usually we just chuck the packaging away.  So great, we all agree.  Aside from getting it to us, Packaging means nothing.  Moving on…

Inside, there is an:
AC Adapter
2 Component adapters (iDevice & Mini USB)
Self Retractable Wire for Charging/Syncing
& of course…
The IMP500 PowerPack

What surprised me was actually how small the IMP500 is.  It is literally the size of a 2007  BlackBerry.  To give you perspective here, it is approximately 40% thicker that the iPhone. Slightly shorter and slight wider than the iPhone as well.  Essentially it is the size of cellular device.  So portability is going to be a cake-walk.  This in combination with the self retracting charge-wire makes portability a dream.  The same wire is used to charge both the IMP500 and the iPhone.  Which makes the need to carry your cumbersome, stock sync cable with you, no longer necessary.  Ah conveninece…Anyway, the IMP500 can be charged via the wall or the USB port on your computer.  Charge time via the wall out of the box is 4 hours.  From 0-100% is 6 hours.  It is also important and worth mentioning, that while for the purpose of this review I will constantly refer to the iPhone, the IMP500 PowerPack is not relegated to the iPhone alone.  No sir!  It is good for just about any portable device as can be seen in the picture on top of this article.  Now time to test this bad boy called the IMP500.

Let me take some time to explain how this works.  Most battery backups that we have seen actually clip into the bottom of the phone itself, no wires.  The IMP500 uses a tether.  So instead of the unit itself clipping itself into the bottom of the phone, the IMP500 uses the included wire.  The wire was ingeniously designed to charge the IMP500 from the wall but also be used to charge the iPhone from the IMP500.  Yes that is correct, the wire serves a dual purpose.  So if you are looking for a backup battery that has no need for wires to charge the iPhone, the IMP500 is not what you are looking for.  However, iMaxPower is actually in development to make such an item (according to my discussion with Mr. Chang).  And yes you can be sure that I will be testing that out for you as well.  So stay tuned.

Now the video said 38 hours video playback.  I wanted to test this for myself and yes, I really did test this.  So I hooked up my 3G already charged to 100%.  Set a few movies to play.  Hooked up the IMP500 to my iPhone hit play, started a stop watch and hit the road to go about my life…

About a day later I checked on the IMP500 and saw that the powerpack was low on battery power.  I watched it carefully from this point on to get the most accurate reading.  The unit died at 16.5 hours.  And the iPhone died 4.5 hours later.  While certainly not disappointed (I mean 21 hrs of video playback is no small feat here), I was surprised considering the 17 hour disparity.  I immediately called Mr. Chang, asking if maybe I had received a defective product.  We went over the test parameters  I performed, together.  We then realized that the original test was done on an iPhone 1st Gen, with all ancillary items turned off including the volume and the fact that the 1st Gen has no 3G.  Hence, it by default has less battery consumption.  On the box it says 25 hour video playback.  Considering the 3G/3GS consume power faster and also the fact that I left everything on; 3G, WiFi, Volume, etc…21 hours for such a small powerpack is extraordinarily impressive.  Let me put it to you this way.  If you have 21 straight hours to watch movies on your iPhone, you have way too much time on your hands, which is not many of us.  So you are not going to need 38 hours anyway.  Yes 17 hours lost seems like a lot, but does not 21 hours also seem like a lot of pure function?  I say a resounding, yes.

21 Hours of constant playback is a flight to China.  CHINA!  Think about that for just a second.  You are going to sleep sometime within that 21 hours.  So 21 hours for such a small compact battery is simply amazing to me.  ”How do they do this ?” you may be asking yourself.  Well aside it being an ancient Chinese Secret, the little known fact about iMaxPower, is that they are no cheap, lame, third party manufacturer for power cells.  No, not like Richard Solo, or iSound who simply dabble in this market.  iMaxPower, secretly, deviously is actually a subsidiary of an actual OEM company that manufactures power cells for some of the largest computer manufacturers in the world.  Now the names of these companies were told to me, but under pain of death I was sworn to secrecy.  And since I forgot my Cyanide Pill, I will not betray my oath of secrecy as I do not do well under torture (just ask my GF) and also, I have too much to live for to sacrifice my life to cater to your passing curiosity.  But take my word for it.  If you decide to get one of the IMP500s’ for yourself?  You are getting an OEM battery, under a different name in a different package.  Now how many companies do you know that can claim that?  So the quality here, now regarding iMaxPower should be incontrovertible.

So let’s talk about the battery simply as an auxiliary power source for charging.  Yes I tested this for you as well.  The IMP500 PowerPack at 100% capacity is good for 4 full recharges of the iPhone before the IMP500 itself, needs to be recharged.  The packaging boasts the IMP500 is good for 500 recharges.  (This I will take their word for.  Sorry guys but that is one area I cannot test in 2 weeks).  The IMP500 comes in two colors.  Black and White.  Retail price for the units vary based on color”

Black/Blue $53.95
White/Blue $49.95

Now why there is a price discrepancy between colors?  I have no idea, but again, I am here to speak about functionality and simply report the facts, not debate them.   From my experience the customer service with iMaxPower is good, they are receptive and accommodating.  The IMP500s’ performance, even though slightly exaggerated performs beyond anything I have seen to date, and iMaxPower’s claim that “This is the most powerful backup battery in the market today” may very well be true.  I can say to date I have not found one to top it.

In summary:

Extreme Portability
Small
Convenient
Very Powerful with 21 hrs video playback
Incredibly, 4 full recharges of the iPhone
Good customer support
&
Reasonably priced

So if you are going someplace where for an extended period of time you have no real access to a wall plug, such as a camping trip, a long flight or an office where the USB port is out, or even just on the go and you forgot to charge your iPhone properly?  You simply cannot go wrong with procuring one for yourself if you are in need of a battery backup.  I give the product a resound thumbs up and the “Hilty seal of approval”.

IMaxPower, the leading manufacturer of premier Lithium Ion battery extenders, announces the release of the long-awaited cableless version of the IMP500.

The IMP500, well known for its 5000mAh worth of juice has been redesigned to go cableless and will be designated as the IMP550, due for release by the end of December this year.

“It’s the IMP500 made sleeker and sexier,” IMaxPower head honcho John Chang asserts with some pride. “You still get the charging capacity you need sans dangling cable.”

The IMP550 will allow you to charge your IPhone up to 4.8 charge cycles at a time and provide you with up to 38 hours of watching videos. This means that when you make a long trip, you’ll run out of energy way before your IPhone does.

Simpler is Better

Just as those who are into Zen preach simplicity for a fuller life, the people behind IMaxPower are striving to provide total customer with the simpler solution. With no cable to worry about, IPhone users can tuck in their thirsty IPhones into the IMP550 and forget it’s even charging. With the IMP550, you can use any generation IPhone while charging without worrying about the cable getting in the way, and it will continue charging even while in your pocket. The redesign was in response to requests by loyal IMaxPower clients to have better ease of use and convenience and IMaxPower promptly went back to the drawing board to give them just that.

Simple, however, doesn’t mean single function. The IMP550 will still retain all the features of the IMP500 including a USB dock that will allow the simultaneous charging of other devices via the optional USB cable. Gadgets such as the IPod, Blackberry, Kindle and Nintendo will still be compatible with the new cableless model, although it will not fit in the cradle. The IMP550 is designed to fit all generations of IPhone and IPod Touch models.

The upcoming IMP550 will still be the workhorse that the current IMP500 is but will be much easier to carry around and use. The sophisticated new design of the IMP550 will provide IPhone users with on-the-go power supply convenience demanded by the mobile generation. Since 2003, clients of IMaxPower have benefited from the excellent products that serve their needs, and customer satisfaction remains the primary objective of the IMP550 designers.

Listening to the radio on your iPhone may not seem like a big deal. Many phones already have this function, and it isn’t normally featured as a big battery drain. However, with the amount of flak that the iPhone battery is getting from users, every little thing that the iPhone does comes in for its share of careful scrutiny.

There are many applications for stream Internet radio that are compatible for IPhones. Most people choose the application that will give them good streaming quality and hopefully not too many commercials to ruin the listening experience, but now considerations of battery consumption also come into play.

Streaming Internet radio applications are different from public radio stations in that they allow users to create a sort of private radio station that features specific music genres and/or artists. This makes it especially appealing for IPhone users who like to play music in the background while they are doing other things, whether on their iPhone or not. There is nothing more distracting than music that irritates or annoys you coming on in the middle of an especially crucial part of what you are working on. It is distracting and, well, annoying.

One of the more popular applications today for streaming Internet radio is Pandora, which can be purchased via iTunes and is currently free of advertisements. The quality of the music is said to be very good, with no static or skipping whether over the 3G network or WiFi.  However, there is a growing concern that Pandora uses quite a bit of juice, especially when accessed over 3G. Reports suggest that accessing radio streams over the WiFi provides lower battery consumption. No benchmark is yet available for actual consumption of the Pandora application.

Another popular application is ooTunes, which can access selections made over other applications such as Pandora. It supports formats in mp3, AAC and WMA, among others. In WiFi, It consumes about 0.17% of your battery per minute of listening to the radio when in mp3 format. In AAC, it consumes 0.148% per minute.

Pocket Tunes uses a whopping 0.3% per minute for mp3 format and a better 0.14% per minute for AAC. Wunder Radio, on the other hand, uses only 0.2% per minute for mp3 but 0.35% for AAC format! So this means that playing on AAC format is not always better. However, it seems to be widely accepted that streaming over the WiFi is definitely less battery consuming than over 3G. More bad news for 3G fans.

On average, using the best possible combination of media format and delivery system, these statistics mean that if you listen to your radio continuously with no other application active, you will zero out your iPhone battery from full charge in about 11 hours and 15 minutes. No big deal, right? Sure, if you only use your IPhone as a radio. But if you do your research and have a clear idea of what your priorities are in choosing the applications you have running, listening to the radio should not become a matter of life or death, at least for your battery.

The IPhone 3GS is Apple’s latest offering to the IPhone fanatics out there, but it still has the battery problem of its predecessors. So despite the added features and higher coolness factor, IPhone 3GS users still search the Internet for posts on ways to extend their IPhone’s battery life.  Listed below are the few tips if you want to know how to save more on IPhone 3Gs battery then read on.

IPhone’s 3GS Battery Saving Tips

1. The usual suspects: Turn off features you don’t need. These include WiFi, Bluetooth, GPS/Location Services, Push email, 3G and Data Roaming. Most of these features can be turned off in Settings; just look for the right button.

2. Not so usual but makes sense is turning off Vibrate alert. In most phones using vibrate is no big deal as it only uses power when you have a call or message, but with IPhone, a little bit goes a long way. That also carries for the IPod Equalizer, which you don’t really need. Both functions can be found in Settings under Sounds.

3. Minimize your game time on your IPhone 3Gs. That’s a drag, for sure, but you need to get your priorities straight with the functions you simply can’t do without, and it is doubtful whether Paper Toss is one of them.

4. Get an IPhone car charger. Whenever you get a chance, plug your IPhone in to extend your happy time. A full charge usually takes about 40 minutes. Then maybe you can play a bit of Paper Toss with an easy conscience and without dreading the battery low warning before you get home.

5. Another idea is to get a good battery extender, preferably one that carries more than one charge at a time. This is especially important when you travel by air all the time, and your travel time is more than four or five hours. An external battery extender such as ImaxPower’s IMP500 carries more than 3 full charges, and they’re coming out with a harness type model so you can tuck your IPhone in without worrying about cables and connectors.

6. Get dim. Reduce your display brightness to as low as it can go without sacrificing visibility, and disable auto-brightness. It won’t really affect how you use your IPhone, and you can also adjust it up when you feel like you have to peer at your screen to read what it says.

7. Filter your phone calls. Yes, you can ignore calls that are not important and allow them to be routed to your voice mail for retrieval later when you have an available wall socket. You will not suffer greatly. Keeping calls to a minimum is a good way to conserve battery life.

8. A neat way to keep better track of your battery usage is to activate the battery percentage feature. It will give you a better picture of how you stand battery-wise at any one time, and give you options for dealing with the issue on a more exact level. Not really earth-shattering, but it’s quite useful. This is only available in 3GS and can be found in Settings, under the General Tab, under Usage.

9. One final suggestion is to lock your phone when not in use. This prevents accidental activation of some functions such as calls, and brings most background functions into standby mode. Set Auto-Lock to activate after a short interval, such as 15 seconds.

Opening up the IPhone can be one of the scariest things you can do with an electronic gadget that you paid top dollar for. You should know your way around a soldering iron as you will need to tiptoe around a lot of sensitive electronics with that hot tip. But if you decide to risk replacing your nonfunctioning battery with a new one yourself anyway rather than paying the $86 or so to have the Apple people do it for you, then follow the instructions below. You will need a replacement battery, a small flat screwdriver and a Phillips screwdriver, a spudger or black stick (a disassembly tool used for manipulating small components, usually made of nylon with a metal hook), a soldering iron, and a lot of care and patience.

1. Remove the SIM tray by finding the small black hole near the jack for the headphones using a paperclip.  This is to avoid damaging it when you open the outer cover.

2. Find the two screws located on either side of the charging dock using the small Phillips screwdriver. Once you’ve removed them, you can start taking off the back cover.

3. Don’t panic, but be careful nevertheless. The back cover may require some force and bending to remove it. Use the flat screwdriver to create a wedge between the black plastic cover and the front of the IPhone. Unless you have a plastic wedge, you’ll probably do some damage to the cover. Lift up from the back and slide the case forward to release it.

4. Carefully detach the ribbon cable that connects the case to the motherboard and set it aside to be reattached after you have replaced your battery.

5. Use the spudger to detach the LCD from the back panel by inserting it between the chrome ring and the front panel. Lift the display panel, and using the spudger release the black ribbon marked with a “1”. Remember to release this black cable first to avoid shorting out the board. Proceed with disconnecting the other ribbon cables. The spudger can be used to disengage the white tab holding the cable. Remove the display panel and set aside.

6. To remove the motherboard, you need to locate and remove eight screws with the Phillips screwdriver. One screw should be located under a warranty sticker. Lastly, detach a ribbon cable marked “4” and lift the motherboard out. There will be a ribbon connecting the board to the camera. Remove the camera from its housing in the back panel, but it will remain attached to the board.

7. Carefully disengage the board from the dock connector using the spudger. It should lift easily if all screws have been removed. Slide it out. The battery should be right in front of you.

6. Using the flat head screwdriver, gently pry up the old battery from the slot, avoiding contact with any of the connecting wires that lead to the system board. Typically, the wires are held in place with sticky glue, which you will have to remove using the flat head screwdriver.

7. With the wires unglued, use the soldering iron to detach the wires, starting from the right, from the connectors on the board. Take note of where the new battery’s wires should be placed. Be careful here. You can ruin your board with the wrong kind of pressure. Remove the old iPhone battery.

8. Your new battery should have three wires, one of which is encased in plastic to prevent touching the other wires and shorting it out. Connect the two exposed wires first with a soldering iron, and then the protected one last. Place the new battery on its slot.

9.  Reconnect all the cables and screws of the motherboard, replace the camera, and attach the ribbons for the display panel. Your IPhone should power up automatically. If it fails to do so, restart the IPhone using the home button.

10. Once the IPhone powers up successfully, you’re done and may replace the outer cover. Don’t forget to reinsert the SIM tray.

Hopefully, everything works fine and dandy. The above instructions only apply to first and second generation IPhones, and there are no guarantees that your IPhone will work after you’ve replaced the battery. Unless you have some experience with electronic repair or have a newer IPhone in the wings, then you should proceed with this operation with extreme prejudice.

The battery life/longevity is a well-known concern among IPhone users. The fact that it essentially sucks has been the one problem that Apple has been unable to lick with any significant degree of success. So instead, they put in a feature in the new IPhone 3GS that will tell users exactly how fast their battery is draining.

The new IPhone 3GS allows users to add a percentage meter right next to the usual battery level icon. So this basically means that users of the 3GS will now be able to know exactly when they should start frantically searching for a power source as their battery’s life inexorably approaches zero. It’s pretty; it’s neat; so I guess it’s pretty neat.

But how does one change the battery meter to show percentage? Don’t get befuddled; just follow these steps to unleash the power of the percentage meter in your IPhone 3GS:

1.    First, go to your home screen and look for the Settings icon. If you don’t know which one it is, it’s usually the gray one with gears.
2.    Tap to enter and you’ll be presented with several tabs. Tap the one for “General” which is usually towards the bottom of the screen.
3.    Find “Usage” where you will find “Battery Percentage”. The default setting is for the feature to be off, so just tap to turn it on.
4.    Go back to the home screen and you should see some numbers with a percent sign next to your battery icon. Voila!

The percentage meter feature is only available in the 3GS model, so if you have an older IPhone don’t bother to look for it at present. It will probably become available to older IPhones when an update is offered so keep this site bookmarked for when that happy event occurs. In the meantime, you’ll just have to be content with the bars in your battery meter, and start thinking recharge when there is only one bar left. That’s a rule of thumb, folks.

One thing about the percentage meter is that it will allow the user to calculate how many minutes of real time it will take to lose 1% of the charge, and you can have some fun experimenting: x minutes for idle time; x minutes for watching video; x minutes for listening music; x minutes for a call. Then you can do this all over again with one or more of the features on i.e. Bluetooth, Push, etc. Hopefully, someone publishes the results online so everybody can benefit from this nifty new feature, even those without a 3GS.

Of course the percentage meter in no way extends the viability of the IPhone 3GS battery in one charge cycle; only an external battery can provide more juice with the portability demanded of most mobile phone users, and in the case of the IPhone not many external batteries have the juice to give more than one charge cycle. The IMP500 from ImaxPower is one of those few who can.

One of the hottest topics in geek gripeville is the short battery life of the IPhone. There are lots of people out there who put in their two cents on how to conserve the battery and extend the battery life of IPhone to at least a full 8 hours. Some comments are helpful, many of them contradictory, some just plain mean. However, the purpose of this article is to get a consensus of what seems to work for most people and to put it out there. Whether the tips are effective or not can only be determined by actually trying it out with your own unit.

1. It seems to be generally accepted that the more features you have turned on, the shorter your battery life. Some people complain that the reason they get the IPhone is because of the features, and if they can’t use it what’s the point? At this point, it would be safe to say that having the feature available and having the feature available all the time are two different scenarios. The capability is there and may be used when needed, which is a pretty reasonable compromise. Sure, other mobile devices with fewer capabilities have much longer battery life, but it will never have the features you may need at any time, so the extended life avails you nothing in this case.

2. The battery life of IPhone is comparable to other 3G phones, so for those who simply cannot live without the 3G features, you’ll just have to lump it, and get an external battery to supplement the battery. Get a good one, one that can give more than one charge cycle per charge. The IMP500 of ImaxPower has gotten some good reviews, mostly because of its price and 5000mAh of juice.

3. Push email has gotten some attention from IPhone users. Apparently, the Push feature can be replaced with the Fetch feature for most people. The Fetch feature only activates at pre-programmed intervals, as opposed to Push that is active at all times. If the need to check email is every hour or so, then the Fetch interval can be specified for that frequency. Some people have claimed that using Fetch instead of Push has extended the life of their IPhone from 4 hours to 8 hours or more. That’s one for benchmarking.

4. There is also a consensus that touches on the strength of the LCD when in use. Most people agree that reducing the brightness of the display significantly extends battery life without much degree of discomfort.

5. There is also the suggestion to check the GPS Location Services every time GPS is activated. The Location Services remain active even when the GPS is no longer in use; this is a default of IPhone for some reason.

Managing your IPhone battery is much like managing anything in life. Prioritize the necessary and important over the unnecessary though important so that all the bases are covered. Anything left over that is gravy.

If you are looking for great deals on Backup Batteries for your IPhones, iTouch, iPod and battery accessories like chargers, usb cables and adapters then IMax Power is the best place to shop.

IMaxPower, the leading manufacturer of the IMP500, the ultimate in the mobile device battery extender is about to launch an even better IMP500 coming this September.

The IMP500, well known for its 5000mAh worth of juice has been redesigned to go cableless. Remember all those other sexy battery extenders that fall short of the ideal capacity in terms of juice? Well, the upcoming latest IMP500 will be sexy AND powerful.
“The new design in no way affects the capacity of the IMP500 in any way,” IMaxPower head honcho John Chang asserts with some pride. “You get the power you expect from the IMP500, it’s just a little more compact and convenient than before.”

The IMP500 will allow you to charge your IPhone up to 4.8 charge cycles at a time and provide you with up to 38 hours of video playback, the biggest type of drain on your battery. This means you can take those transcontinental hops in your stride with no problem.
100% Customer Satisfaction.

The people behind IMaxPower have always prided themselves on customer satisfaction and are always striving to improve the product to give better performance and convenience. In rising to the challenge of meeting the demands of their most critical of clients, they have upgraded the design to allow the IPhone user to slip the device into the holster to charge it; no need for a cable.

However, there is a very important plus to the new IMP500: it also features a USB dock that will allow the simultaneous charging of other devices via the optional USB cable. So the new IMP500 will still retain its multifunctional capabilities in the sense that it can still provide additional power to other gadgets such as the IPod Blackberry, Kindle, Nintendo DS and so on, just like the current IMP500 model. Isn’t that just peachy?

Moreover, the new IMP500 will retain many of the great features of the current IMP500 model. You can choose to charge the IMP500 itself with the rapid AC charger (available online at a minimal additional cost when ordered with the unit) or the accompanying USB charger that you can plug into your portable or desktop computer. With the rapid AC charger, the IMP500 is fully loaded and ready to go in as little as 1.5 hours.

And of course, the upcoming new IMP500 model will still be as sleek and attractive as ever, hiding a workhorse persona behind a sophisticated façade. With the lightweight new IMP500, you can use any generation IPhone while charging without worrying about the cable getting in the way, and it will continue charging even while in your pocket.

The new IMP500 is guaranteed to work harder that ever to provide you with on-the-go power supply convenience so that you too can be as mobile as you want to be without sacrificing necessary (and fun) applications. IMaxPower has been in the battery extender business since 2003, and customer satisfaction is its primary objective. The geniuses behind IMaxPower continue to be driven to go beyond expectations of its customers by unremitting research and development to improve an amazing product.

Here’s to better mobility! Cheers!
