Why does my battery go down at night?

[frankieg22x]

here is mine so you have an idea.

35% display
19% cell standby
11% phone idle
8% android system
6% browser
3% voice calls
3% market
2% swype

There are a few others running as well, but they arn't doing much.

I would say that my battery was about 50-60% when i went to bed last night and is now at 40% (didn't charge it last night). Your battery might be bad.

Most phone use lots more power when in fringe areas trying to poll for signal.
Some will turn off and only poll every 30min or so to conserve battery but without such a setting it will pull the battery down faster.

Leaving it on the charger while sleeping will not only ensure the battery last longer but it will also be a moot point as to what the energy expenditure is.

plugging in over night is one way of avoiding this. someone correct me if i'm wrong but i read somewhere that its best to keep lithium batteries above 40% charge anyways

No, not true at all. No basis in fact whatsoever, actually.
