On a four hour flight this past weekend, I shut my stock 1.12.605.6 ThunderBolt off completely by holding the power button, then selecting "Power off". The battery level was at 68% at the time. When I landed and booted back up, my battery was at 17%. That's a 51% drop over a four hour period with the phone powered off.
To test it further, on the way back, I set the phone to airplane mode. The battery was at 71%. At the end of the four hour flight, I powered up the screen to see that the battery was at 68%. That's a 3% drop over a four hour period with the phone powered on, but all the radios (and the screen) off.
Has anyone experienced this?
That is strange. Have you reset the battery stats?

That's weird. Turning on/restarting your phone drains some battery, but not that much... I'd just leave my phone on airplane mode...

You need to clear battery stats or condition you battery with bump charges....when I first got my phone I charged it to 100% then unplugged it and immediately rebooted and it dropped to 78%. The batts are just weird imo

It didn't actually drop that much. It wasn't reporting the battery % right. Either before or after the reboot.

I've had my phone less than a week. Since I got it the screen has shut off after not being used for 2 minutes pretty consistantly till yesterday, and battery life was ok. Now, its just staying on all the time(dims after a few seconds idle, but doesn't go out). And my battery has been draining very fast, like full charge at 9am to dead at noon after a half hour call and a few texts. I can't figure out whats doing it. It is still set to shut off after 2 minutes when not on charger.

Mine shuts off except when on charger even tho I have it set to go off after a min. I just put it to sleep by touching the power button. I do this to save battery and avoid an unwanted press as I'm a pocket guy. Does yours go off with a press of the power button?
yes when i push the power button it still shuts off
So often, before I go to bed, I would charge up the phone completely and turn it off. 8 hours later, I turn it on, and the battery is at 70~80 ish.
Yesterday however, I just put the phone on airplane mode without turning it off, thinking it might make a difference. I woke up and the battery was 99%.
WTF?

Because when you turn on airplane mode, you turn off radio, wifi, etc about signal and data. It is about 50-70% power consumption. Consequently, when data is cut off, apps that needs to update via data, either wifi or mobile, won't update. That is another less stress on the battery. So on and so forth.

Well that's weird cause I put my phone on sleep last night without airplane mode and with 3g on, and it went from 90% to 87% by 7am. Maybe it has to do with low signal? I know when I have low signal my battery drops SUPER fast.

You totally failed to understand my problem. I'm saying airplane mode with phone ON consumes LESS battery than turning the phone completely OFF

I completely misunderstood your problem. Hmmm, in THAT case only thing I can think of is the phone not being shutdown properly. Aka the phone got stuck in a low level state with the screen off/unresponsive but maybe the phone was still processing network information. Then when you turned it on, you shut it off and turned it back on without really noticing.
That, or the FBI has been tracking you in the night.
We still didn't answer his question! Its weird that the battery is getting drained with the phone completely off.

How about telling us also what rom/kernel you are using?

I had an issue with my phone charging, it would take about 18 hours to charge the battery completely. Turned out the cord had gotten screwed up somehow. Also if you're using a USB extention cable, if you use more than one it will do something similar.
Charge your phone, turn it off, remove the battery and check if it still looses power.. so we will know if it s a battery problem or phone drainage problem
1. rom/kernel: cm 7.1.0.1, default cm7 kernel
2. update: second night with this Rom, and when i turned it off and on again 8 hrs later, it was 91%. Not bad.
3. I have charged full> powered down> removed battery> 8hrs later> insert battery & power ON, battery is full.
4. Computer USB charging takes probably over twice as long compared to using the outlet adapter.
I understand that phone goes into a low power state when it is turned "OFF", but really, what gives?

I have a feeling that the phone is not shutting off all the way. How about trying to shut down your phone, pull the battery, reinsert it, but DON'T turn your phone on and don't touch the power button at all, just reinsert it. Wait 8 hours, check it then.
running the sgh-i727r.
had the phone since boxing day and this was the first time it happened. went to sleep with about 70%, slept for 6 hours and then woke up to a turned off phone. turned it back on and battery showed a huge drop from when it turned itself off, shortly before i woke up.
the only battery saving app i have is juice defender, on balanced profile.
any ideas?
thanks in advance.
Download betterbatterystats from the market and find out what is using your battery...
Are you rooted? if so.. reboot into recovery and erase battery stats and calibrate your battery..
More then likely have an app running..
Hey guys. I always restart my phone before I go to bed, and I never charge it overnight. I just charge it the 1,5 hrs I have before I leave the house in the morning.
Usually this works fine, but this morning the phone was very hot. Very very hot. I've never held a so hot handset before. I had to hold down power and volume to even get it on.
It went from 60-ish to 27% overnight and as you can see from the screenshot, there's a hole in the graph, with no apps apparently being logged as consumers overnight.
Anyone got any ideas about this?

might want to do a full charge and see if problem persists. meaning 0-100%
1. Clear all app in task manager. Restart phone sometimes.
2. To force phone shutdown, press both Power button + Volume up button at same time.
According to the battery usage screen, about 15% of the battery has been used. And yet, it's in freefall. At 34% I got a low battery warning saying the battery would only last another three hours, even though it was dropping about 1% a minute.
Just randomly happened today. Left it unplugged overnight with Sleep as Android running, woke up to about 70% battery, started browsing on Chrome and Talon for Twitter, and 15 minutes later I had 20% battery. Plugged it in, got it back up to 75%, had to go out. Felt it get hot, checked, saw it was still dropping dramatically. Turned it off, left it to cool, turned it back on, and it continued dropping.
I had it turned off for a while to cool down after I'd plugged it in, as well.
Battery Usage does list Sleep as using 22% battery, but that's since the last full charge so I assume includes what it did overnight, which jives with having a percentage in the 70s when I awoke. Talon, Chrome, Facebook, TiBu, and a couple of other apps are listed as using 1-2% of the battery. That's it.
WTF is going on?

I think the battery might need to be replaced...after I charged my phone to 100% and then reboot, it will show 69% or 70% after the reboot -_-|. Also when the battery % drops down below 50%, my phone could switch off anytime - and then when I switch it on again, the battery is like 1%. I am using this phone as a backup just to receive messages so I don't mind it too much. If you use it as a main phone maybe it is time to upgrade to a newer model...the battery on regular Pixels were not so good even when new...
When the phone is off charge it to 100% then use it until it dies completly, then try to start it couple of times(it should just show a battery low icon or turn off while booting). Then charge it to 100% again while turned off.
This should pretty much reset the electronics in the phone. If it still does it replace the battery.
P.S.: Also look at the phone from the sides to see if you notice any glass poping (just in case the battery has started to expand)
