Android 2.2 battery life problems?

[BKS]

I read doing a factory reset may solve this issue. Has this worked for anyone else? Whats at risk if I do this?

TIA!

I found yesyerday that the stupid Facebook app is what was really draining me. I turned off the sync and overnight I lost 10% battery versus the usual 50% I normally lose. I don't need realtime facebook notifications. I will be curious to see how long that gets me today.

I will avidly read this thread if anybody comes up with a solution. My battery life with 2.2 is horrible. It's hard to get through the day. I think I've got everything trimmed down as much as possible (including FB only syncing on request by me) and yesterday I had to have it plugged in on the drive home so I could make it home. Normally I end the day 18 hours after I unplug it with 40% left. Paint me unhappy.

2.2 is awesome.. if you think otherwise you have something wrong

as for the battery issue. make double sure the battery is fully charged then go into recovery and clear the battery cache. that should fix your battery

2.2 is awesome, agreed I am going to have to try charging 100% and clearing the cache. Is that just an option off the main screen in clockwork?

its under the advanced menu

thanks, I just did that after I made sure it was 100% charged. We'll see how long I get the rest of the day. Can you explain exactly what that does? What is the phone keeping a cache of exactly that could be causing it to degrade quickly?

...Before I go to Verizon & light their asses up, I'll give this a try in about an hour once the batt is fully charged...because the longest my phone is holding a charge now is 4hrs with almost zero usage!! :icon_evil:

also, if the phone ever got really hot the battery is probably toast.. they replaced mine under warranty about 3 months ago after the phone bricked and overheated.

I cant say i know exactly what the battery cache does, but I "think" it has to do with the phone remembering what voltage means 100% and what voltage means 0%, but dont quote me on that at all.

What advanced menu? How do I get to this?

 

[Wadzii]

you need to be rooted and have clockwork recovery installed.. .then boot into recovery, goto advanced, then clear battery cache.

if you have none of the above there are lots of how-to's around here....

 

[ruinah]

man, I wish someone would have told me about all those cache settings a while back. I cleared the battery cache and it shows me 89% left after 2.5 hours and I was steaming the NFL Network channel for about 15 minutes there for a bit. That, and work emails of course. I cleared the other caches using one of the apps in the market and the phone seems a lot snappier now.

 

[Wadzii]

Make sure you let it drain till it dies this first time after you clear the cache

Thanks...didn't realize we were talking about a root thing here.
