Normal for battery to drop 10% overnight

[joepa150]

I fully charged my battery on my S2, unplugged it, and then slept for 8 hours. Battery dropped down to 90%. I looked at what was eating up my battery. The first two were Android system and Android operating system (can't remember the order).

Is this drop normal for standyby?

I guess it is a little over 1% per hour.

Interested in this too

That sounds good actually. Unless you're in airplane mode you still have radios on and they draw power, plus any app that may need to run in the background.

From At&T and phonescoop, the S2 is supposed to have about 384-400 hours max standby. If I drop 10% every 8 hours, wouldn't that be 80 hours standby?

Maybe that's assuming all radios turned off with no apps running in the background

I'd be thrilled if I only lost 10% in 8 hours. I can pretty much guarantee that my phone would be dead in the morning if I didn't charge it or turn it off overnight....unless it was at 50% battery or so.

Of course, this wasn't an issue before the "update".

If you're running 2.3.6 with WiFi turns ON, then it is normal. Look at the other thread "Battery drain with new update." It talks about the new release 2.3.6 causing a lot battery problem than 2.3.4 and most likely by the WiFi. I right now have my WiFi turns OFF until I actually use it.

HTH.

I believe that it's the way standby time is measured.
It all depends what it's running. If you are in airplane mode with no apps running you may see a drop of only a few %

I didn't do the update so I have 2.3.4.
I do kill the apps running in background but I always have wifi on.

Maybe tonight I will turn wifi off and test it out.

maybe you downloaded some junk apps and they are running in the background.
