i think it has been discussed at length here that the battery issue is an indication only problem, the level indicated drops early and gets low fast but still lasts a long time, i am getting 22+ hours on a charge, if you turn off data sync you may lose other features as a lot of them are linked together

 

I do not want to sound rude when I say this, but this is incorrect. I have had Backgroud data on since I bought the phone, my phone sleeps properly. I can get almost 2 days with moderate usage and I can get through a normal 16-20 hour day with pretty heavy usage.

Your problem is most likely some application you have installed that is constantly using data in the background and not allowing your phone to sleep. Turning off background data for the entire phone does stop it, but it is not the actual cause. Your solution is like cutting off blood flow to your entire leg to get a cut on your toe to stop bleeding.

Your best bet is to figure out what app is causing the problem and then remove it or see if settings within can be changed to stop it from using background data constantly.

 

i already saw some improvement limiting some of the fetch settings.
ill post back with results!

 

Full drain and recharge

 

The most common culprit is a weather app, if I recall, sprint has a weather widget installed on the home screen by default. That and the NFL/NASCAR apps were the first things I canned.

 

Especially if in your weather app, you have it set to use GPS to follow you around instead of having (a) set location(s).

 

Market doesn't work without background data enabled. I get 36 hours of battery life with it enabled so I don't think this is the problem.

 

Yeah I figured that would happen, I get good results just leaving gps, bluetooth, and wifi off unless I need it, turning off any of the data or google apps will take down marketplace and some other stuff as well

 

By the way, good analogy.

 

Dang zumaki! i wish i got that much.
Low service makes for poor battery life as well.
If you stay on 3g, you'll have better battery life.
I dont' get this luxury though, but I still get at least 8-12 hours. Phone has to spend more time on the network, thus less battery left.

Anyways.

The not sleeping issue has to do with widgets and things people install.
I tested this out first thing with spare parts, i was afraid. Hell. I use my phone for a few hours, and it will say its slept 90% of the time I've had it out.
So, in order for it to not have sleeping problems, you have to have something installed for it to stay awake. Cause not many things run in the background while its in standby.
