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 cant use it whats 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 will 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 New Trent 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. Thats 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.
