Title says it all... just restarted my phone to find the battery stats had dropped very significantly. thought it was a fluke so i went into recovery, deleted battery stats, and still the drop was present upon next restart.
not only that the other day i lost 30% overnight while it was powered off!!!
this is a fairly new anker battery.... it shouldnt go to crap overnight shouldt it? they have extremely high reviews!
this power drop during restart happened just after i had left the battery out of the phone all night!! Went in at the same power level as the night before, i used it some, restarted, and boom 22% missing...
just did another battery pull and it lost 3 more %. before this, this battery was perfect!! 1 random wakelock in about 6 months time. I dont get it. this is not a gradual degrading of battery, this is downright crap
Try calibrate the battery

Should take a titanium backup of apps. Move that folder to ext sd card and factory reset the device.
Problem must go away

Probably it was 22% lower the whole time but it was displaying incorrectly. Try calibrating the battery.
Already tried this... Just had it lose 30% again... A program froze and I had to manually restart (hold power button down), went from 60-33%... It was only frozen for about 30 seconds... This battery is only less than 6 months old. I just gave it a full drain until power off, and then a full uninterrupted charge while powered off like everywhere suggests.... And it's still messed.
What else could be wrong?!
With the initial restart it wasn't even a freeze, it was a restart from the power menu... Any battery app I have just reads from the phones main power meter, not it's own...
This is so frustrating...
Eta: why would a factory reset of software fix an external hardware problem? Plus I just reset a couple of months ago, it's really not that old and bogged down of a system....
Bad battery. Let it run all the way down to it dies. Then charge it all the way too 100 the. Turn on the phone and keep it on the charger for an hour and then run like you normally do and see that helps. I do this with all my phone and it works you should do it once a month to keep it healthy .
Have your battery tested to see if it is a bad one. Is it swollen at all even a lil bit?

so why exactly am i losing battery life on a reboot. its happening on every rom ive used so far.
I think its because your battery is not properly calibrated with the rom. Are you bump charging each new rom you put on and wiping the battery stats?
This happens to me. I am stock currently, but I have been through two phones and they both lost 5 - 10% on reboot.
It's normal for the phone, it takes a bit to "power" up the phone. Don't stress out that much over it. The battery % isn't 100% accurate anyway.
I'm losing ~10% on each reboot too. Its definitely not just from the reboot and I don't think its accurate. Yesterday, as an example, I was at 43%, rebooted and came up at 32%. Then my phone sat 32% forever, just flat lined in the battery stats for hours. It finally started reasonably dropping again hours and hours later as if the battery level had finally caught up with what was being reported.
Have you ever bump charged and battery wipe stats before?
Cuz mmy battery doesn't drop like that.
I don't think I lose a full 10%, but I definitely notice a significant, if not excessive battery drop when rebooting. It seems unlikely that the battery could have discharged that much, so it's probably a reporting issue. Not something that really bothers me, but just pointing out that I noticed it as well.

This was similar to what I experience. More evidence that it is a mostly harmless reporting error. The reporting "corrects" itself once the phone is booted. Interesting behavior, but harmless.

Your battery gague isn't telling you the truth.
I don't even get a 100% charge. It sits at 97 for like 3 hours and then drops. Reboot usually only takes <5 for me though. I'm thinking ROM issue.

This really explains why you drop rapidly after unplugging your pone from charging to "100%". I believe the OP is referring to a step function-like decrease in battery level between reboots. That is what I'm referring to anyways. That link does have some interesting info though.
I've been having the same issue. Reboot sometimes drops the battery by 5%, and the battery gauge seems to get stuck after that. I've also noticed that sometimes if I reboot while it's charging, the % will jump something ridiculous like 20%. Just now, it was at 45% while charging, I rebooted, and now it's at 57%.
This has been happening on both BAMF and CM7, though I've always been using Imoseyon's kernels.
Same problem here. Bump charge and battery stat wipe is the fix but it's definitely a pain. Especially, since I am flashing a new rom everyday.
to bump charge does my phone have to be off or when it reaches 100 unplug and plug a few times? will that do. i hate having to shut the phone off especially for a number of hours.
Bump charge> charge the phone on till light turns green. > turn phone off> charge phone until light turns green> unplug and reconnect several times> boot into recovery> wipe battery stats. > done. Use the phone all day and let it die on that charge. Then charge over night turned on. And you are now calibrated.

because rebooting entails the re-starting of operating system, services, background apps, internet connectivity, and initial data sync. it's just the nature of restarting an operating system.

I think the question was meant to be something like, "why do I lose 5-10% of my battery after a reboot?" Of course rebooting using a little power, but that's not the issue here.

Because the battery gauge isn't reading it right. Solution. Bump charge and battery wipe stats.
I've installed the Yelp, Movies, and Amazon app, nothing else, and I'm losing around 15% an hour with light/normal usage.
I've let the battery run down to 0 and recharged completely, I've turned off gps and wifi, and still get really bad life. I live in the Bay Area and get a solid signal all of the time. There's really no excuse for it.
Please don't tell me to flash to a rom, because that's obviously not fixing the issue. Light browsing and the occasional Google Maps has my phone at <20% by the afternoon.
Battery stats just show android system and screen brightness taking up power. What's the deal?
I also constantly have at least 255 / 328mb in use even with all applications closed.

The mb usage is normal i noticed this on stock because of Verizon apps that run in background. As far as not using the phone and only getting 6 good hours of use. i would take to the store and ask if they could change out the battery. Hope this helps.
+1 for that, sounds like you have a defective battery.

Thats about how long my battery gets me.
And if I forget to power down my phone at night, or put it on a charger it is dead by morning no matter how much of a charge it has before I go to bed.
I have an extended battery starring me in the face and can't use it yet since I couldn't find a door and had to have one shipped from Samsung.
Hopefully the extended battery cures my issues.

I am curious as to what you guys are running. And if you go to bed with your phone on , and its dead by morning I can PROMISE you there is either something going on with your phone, or you are doing something wrong (i.e. you have your phone set to never sleep, your screen is set to maximum brightness, your are leaving your phone in desk cradle mode, etc etc etc.) But it's not the phone. May be a bad battery, but without being at your house and seeing what you are doing, I have no intelligent answer for you.

charge phone to 100%, boot into clockwork recovery and wipe your battery stats, then use the phone until you completely drain your battery until it shuts off. Then charge back up completely. This will calibrate your battery. try running a customer rom such as gummy charged or humble to see if you get bettery battery life... thousands of users have reported great battery life with both
I had same crummy battery life. I followed the calibration instructions and i went from about 5-6 hr batt life to ( right now im at almost 11hrs with 66% battery left on wifi with moderate use). Ill test tomorrow on 4g only and see how it does. I would get like 4-5 hrs before.

I am running the latest humble and my battery drops really fast. If I go into task manager and clear my RAM, I get better battery. I calibrated per the instructions as well about a week ago or so and saw no improvement. Please note that I have not been scientific about it at all.
Stopping Data obv helps a million and clearing RAM seems to help as well.
EDIT: I am recalibrating in case it was not done properly before. Hopefully it will help. I am hopeful!
I charged my battery to full, booted into clockwork recovery and wiped my battery stats.
When I rebooted my phone it shows a 73% charge?

If you are on humble 1.x then that means your battery stats were way off. Basically your battery still needs 23% more charge before its full... thus better battery life... because you had a miscalibrated battery, your phone is erroneously reporting a full charge... charge it back to 100% then discharge fully then charge all the back up

I'm on Gummy Charge GRE, but I assume the same reason?
I exchanged my battery at verizon. So far it seems better. Ive let it drain and am recharging now. I will also try uninstalling g+ if the new batt hasnt solved the problem. I will post back with an update.

I switched out my battery 2 days ago, and I'm still getting under 6 hours with moderate use.
Has anyone had luck with ROMs drastically improving battery life? I can't imagine it being the phone itself, but I might try exchanging it too.
EDIT: it seems like the new battery charges a bit faster. My old battery would take around a minute for one percentage gain. Can anyone comment on their charge times?
weird situation?
ok so yesturday i flashed over the new humble.
and well i left it charging iver night.
when i woke up my i disconnected the charger and took off.
when i checked my battery stat and what was using it.
my display was at 49%
i have never had it this low its always 75% and up.
and during the time.i had it down in the 40s. it hardly wasted any battery.
and now i restarted my phone and screen is back to 89% -.-
and i havent used it at all and ita been 4 hours and am down to 88% battery only with phon at idle in my pocket. ohh and i had data off..
wat is going on!?
You need to calibrate your battery. The easiest way to do it is to use the battery calibration app you can get from the Market. Put it on the charger and wait until it is 100%, and before you unplug it, run the calibration app and press the button. After it's done, take it off the charger. For best results, you need to then completely drain the phone without ever plugging it back in and then completely recharge it again without ever unplugging it. However, just doing the initial calibration will help you out a lot.
what do u mean the initial calibration?
and do u know why my display was really low? n stayed like that?
untill i rebooted
I'm having issues with my phone shutting off when the battery meter is low but not dead.The indicator will be yellow and still shut off. When I power it back on and plug it in, its completely dead .
is the phone innacurately reporting the battery percentage?
Sounds like the battery isn't conditioned correctly. There are apps in the market to help with that.
Look in battery configs battstats prob in /data/system and prob elsewhere
Sent from my HTC VLE_U using xda premium
Arent there other ways to condition the battery with an app? i heard like running the phone to empty and then fully charging? any advice?
The problem with running it empty is the battery will never fully discharge because the phone is reading the stats incorrectly.
can you recommend any specific app for this? do you have to be rooted?
You'd have to look at the requirements per app but I do believe you need root.
Your phone isn't going to report one thing, but "believe" a different thing because of bad battery stats. A Google employee has already debunked "conditioning" your battery by deleting battery stats; the phone uses it for reference only, not to make any decisions, especially when to shut down. Something is wrong with the battery itself, or your phone, not your stats.
Swyped, not typed, from my Digital Brick
It might be better over time. Had mine for two weeks now, and I had it run out on me three times. First time it shut down at about 13% left on the meter, second time around 8% and this last time at 2%. Good enough for me, but it's annoying if an untampered new phone doesn't report at least somewhat close to real battery-state.
I usually hook it on the charger at 15%-30% (approx 12-16 hours usage) in the evening, and sometimes have a few short charges (25-30 minutes) from the car-charger during the day.
I've never let mine get below 50% since I got it, but I just ran it into the ground with a terminal process ('yes && yes') and it went all the way to 0% and then powered off.
Hello, not sure if this is the right page to request this type of help but here's the deal: the last few days I've been having a sudden crazy battery drain... I cleared the cache, then performed a factory reset and the battery was still draining - around 1.5% per minute with the screen on. Around 1% every 3-4 minutes with the screen off. I read an article about Safe Mode.. and before I got into Safe Mode I had 23% battery... when I got into Safe Mode.. it showed me 62%. I got back into "normal" mode and it still showed 62... now it's currently at 60%. Thought this is weird.. any idea what's going on?
Either bad calibration or a dying battery. Do a full cycle (run it till it's dead then charge it to full before booting). If you still experience problems you should probably get the battery replaced.

It seems to be ok for now.. It hasn't discharged yet.. will let it turn off on 0 battery and then charge it full. Thanks.
Calibration can go out if you regularly charge it when it's not empty yet. Modern batteries dont have as many problems with memory, but it's still possible.
