Here is a guide in a nutshell on how to increase battery performance. This is from personal experience and from other tips I've seen scattered here and there.

1. Lower your expectations. These devices are small powerhouses and more power = higher battery drain. Mobile technology always seems to be out-winning battery technology. So we see many upgrades to chips, processors, rams, etc but still using the same li-ion batteries. Not much improvement in battery technology.
2. Greater power drain in lower signal areas. This includes inside buildings with thick reinforced concrete walling. It's also true when your phone goes in and out of roaming.
3. Higher brightness settings = more power drain. This is especially true for light sensing capabilities which is always polling the environment for changes in light. This is also sure to draw more power. Field workers and those in brighter lighting conditions are also sure to experience an automatic higher brightness.
4. More power drain with higher speed evdo vs 1xrtt only. So, if you don't need it, force 1xrtt only. Manually or automatically switching between the two will also drain the batter. So, it's a catch 22.
5. Along the same lines is using exchange.
5. Constant soft resetting I have found is also to increase battery usage. Only do this when necessary. (based only on anecdotal evidence).
6. Even if wifi and bluetooth radios are on in standby they still drain power. There are supposed registry changes one can make to reduce frequency of polling mechanisms and these have shown to show SOME improvement.
7. Anecdotal experience but - simultaneous use of bluetooth, radio and wifi is sure to have a net increase in power draw than using each of those separately.
8. Radio versions. Hopefully sprint will come out with future updates to enhance efficiency of the Radio with software upgrades. These sometimes improve battery.
9. Anecdotal experience - with more processes, programs or whatever loaded into the memory comes greater ram usage. More ram usage = more battery drain. Close programs you don't necessarily need running in the background. I don't know if this applies to apps running in memory while phone is in standby.

Here are some other tips to save battery:

1. Turn of gps location under phone settings. Users have reported better battery life.
2. Don't keep hitting button on and off. Try to do whatever it is you want when you hit that power button.
3. If you don't need push email on the instant change settings to manual or decrease frequency time.
4. Turn off phone radio during times that you know you won't need it.
5. Treat your battery better. Don't charge unless you're going to charge up to 100%. Carry spares around to increase overall life of both stock and backup battery. Don't store phone in heated conditions. Store unused batteries in cool environment with a little less than 50% of the charge left. Invest in an extended battery when it comes out.
6. Underclock processor. This is yet to be determined. Don't try anything now until software developers add TP to compatibility list. I remember that with my 6700 underclocking would actually increase battery drain!
7. Remain vigilant of apps that update frequently (e.g. weather). Also remain vigilant of apps that use active data connection and keep it active for no apparent reason. This could possibly be due to glitches in app itself. I have noticed this phenomena sometimes where the data arrows will just stay on white for a long time though no data transfer appears to be occurring.
