[Q] battery drains when phone is shut down

my lg g2x drains my battery when turned off
the most previous experience was last night when i had my battery at 39 percent when i turned it off the next morning when i turned it on it was at 19%...
At first i thought it was the faux's DebouchedSloth (the one with the funky readings) so i paid no mind to it. (i just left it on during the night in airplane mode, which actually gave me better battery life) Later, i flashed the trinity kernel, only to find out the same thing happens
what do i do?
im running the latest cm7 kang build from baldwinguy77 with trinity kernel T15max 20122011 if thats any help.
thanks in advance

try a "battery calibration"
let it drain out completely and then let it charge 1 to 2 hours extra after it has reached 100%. worth a shot but i doubt it will help
or try wiping battery status in recovery
also, set up setCPU with profiles

Hmm.. I wonder how the battery drains even though it is off? o_o
Did you try turning it off, than remove the battery and put it back in? And see if it drains.
For me, my battery drains 0% overnight on airplane mode.

I just want to make sure when you say you turned your phone off you mean you shut it down right? I'm just trying to get a answer out of the way because I have seen so many post go a long way only to find out the original post misinterpreted a phrase. If it was in sleep mode a 20% battery drain isn't terrible. I've seen better and worse. If it's draining while it's shut off then I ask are you using the stock battery? It seems to be a big issue and I could easily see it leaking energy while off or giving misread.

there was an article on the xda homepage posted not that long ago. it was about how battery calabration doesnt effect battery life, but only the battery graph found under settings. basicaly it said that the batterystats.bin file only has to do with that battery graph, it tells the phone whats been eating the battery. here it the link if you want to read the article:
http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/
anyways back to the point. nope i calibrated my battery a few days ago, so it didnt help

i dont know... and i used to leave it on overnight in airplane mode too with faux's kernel, it drained alot less leaving it on over night then turning it off. but the thing is, leaving you phone on for too long makes it sluggish, so i want to turn it off once in a while to help make it more snappy. I wanted to try that with trinity kernel, but ya thats not really working lool

for me my phone has none of the problems that most g2x,s do until i use any faux's kernel,s all rom combos all correct faux's kernel combos don't know why wasn't always that way

I would suggest trying a new battery first. I purchased a couple of 3rd party batteries for $20. If it still drains while the phone is OFF, you have some sort of internal hardware problem.

sometimes it's the ROM, i've tried EaglesBlood, PheonixBlood and i get above then norm battery life. I'm on Xboard's OTA and my battery life is sweet

i'm having the same issue as well even when using 2 different batteries and an external charger (for the battery itself).
'normal' drain on the eaglesblood AOSP is about 20% an hour and when I turn off the phone, remove the battery, put it back in, and turn it back on after an hour, the battery drains till it's almost empty!
maxesxp, did the new batteries work? or was it some combination of rom + kernel that did the trick for you?

Weird I just thoughts about looking for this cause I had this happen for the first time. I was at 40% had no charger around so turned the phone off, turned it on the next morning and was at 2% effing weird!

My phone does this too. Some days it will drain only a percent or two and others it will drain like 20-30%. From what I can tell the kernel or something is not turning everything off on the phone. Try turning your phone off the next time you do and remove the battery and then when you go to turn it on put the battery back in and see if it drained then. If it did then it is a problem with the battery and if not it is a problem with the phone. If it is the phone there is not much you can do about that, sorry.

Battery Dies Quick, WHY??

my NS4G with MIUI 2.6.1 and Matrix 20.0 Kernal goes to 98% as soon as i pull off the charger. if i use it for 45 minutes unplugged its dead. if i use it while its plugged in, it will die!
should i get a new battery?

Yeah that doesn't happen to me... I would try a full wipe and reflash the same ROM (or a different one) and reflash kernel.
If that doesn't work then I would try another battery because that drain seems abnormal

I just wanted to say that I have been having similar battery problems. Using the exact same ROM and Kernel as the OP, today my phone died within 6 hours of use, with the screen having been on for no more than 50 minutes. I also turned off data, and sync during this time, and had my screen's brightness at the minimum.
I've wiped and flashed AOKP b-38 today, and the consumption seems to be much better.
Any thing to help?

thought i was the only one.
is it the kernal?
or is it because its time for a new battery?
How could I test to find out which it is...

Swap kernels. Probably easiest way to test.
Very possible its just an old worn out battery.
Sent by pocket technology.

hoping its just an old battery.
ive switched to CM9 / TouchWiz mod thinking it might be the ROM
im going to use the stock kernal from CM9 for a day to see if i could tell a difference.
ordered a new battery anyways.
saw on a forum somewhere a guy complaining about this problem since he switched to ICS ROMs .. hopefully thats not the case because i LOVE 4.0.X

If it were processes/functionality causing your battery drain, that quick, the phone would be piping hot at the same time!

yes, the screen also gets EXTREMELY hot!

Well in that case, what have you got installed? If you have apps constantly syncing, that could be part of the problem. What are your battery stats saying is using the most battery? My phone gets warm, but as expected since its being used. If its not being used,it could be a rogue app or the phone could be constantly searching for a good signal.

i have barely any apps.
i only have facebook, xda, sportscenter and instagram installed besides GApps.
i have the problem even before i download apps as i just flashed CM9
also its so bad, that if i start using my battery when its @ 10% PLUGGED IN, it will eventually die on me. even though its charging..

Some more crazy battery antics

So a couple weeks ago I went to bed with my phone unplugged with maybe 80% juice left. Woke up, phone was completely dead and refused to turn on, even after sitting on a charger for 20 minutes. The only way I was able to get it to boot was through recovery. I checked my battery stats and it showed that it dropped steadily to maybe 65% over the course of 4 hours and then dropped straight to zero from 65%. I chalked it up to issues with my ROM because I was having other quirks here and there. The other day I flashed CleanROM 4.5 and everything was gravy. I also flashed the radio from 2.20 and had great signal and LTE speed increases after the flash.
Last night I decided to see how well my phone was sleeping so I took it off the charger at about 11 with 100% charge. When I unplugged it the phone was very warm and was reading about 110 F. I killed everything just to be safe. This morning at 8 my phone was down from full to 75%. WTF. I used to lose MAYBE 2% over night so 25% is a massive drop for me. I plugged it in to my MBP to charge (like I always do) and as soon as I did I got a warning message saying my phone was using more current than the charger could output and the battery dropped instantly from 75% to 18%. I am going to flash a different radio but I am not hopeful that it will solve this considering it has happened with two completely different ROM/Radio combos. I have checked betterbatterystats and even had system panel on monitor all night and nothing was out of the ordinary. Cell standby was at the top of the list in the stock battery stats but that seems normal to me considering I didn't turn the screen on once. There was no time without signal. Has anyone else experienced this issue? What do you guys think- hardware or software?

Couple weeks ago, sometime after flashing the rooted stock 2.23 and 2.23 radio, I had the issue of the battery being dead overnight. It was something like 70% when I went to bed, so I was surprised it died. I typically get more drainage while idle than you, but still usually only 2 to 3% per hour. Even less on the 2.23 radio, around 1.5% (or less) an hour while idle.
Hasn't happened since. I'm still wondering what happened?

This happened to me once as well, dropped from 70% to completely dead overnight. I could not figure out why, but it hasn't recurred.

It's a virus!

I'm having a ton of awake time with very little screen on time when using aokp/cm10.
Sent from my One X using xda app-developers app

Yeah I have no idea what's going on. Now it seems to be fine, and I haven't done anything to it yet. Took it off the charger at noon with about 80% on it, now it's almost 9 and I'm at 65% with 33min screen time and 30 minutes of voice calls. Pretty good for only a 15% drop. Really confused. Gonna charge it up all the way and unplug it again before bed to see if the same thing happens again.

Definatly.
My battery has been absolute crap the last 2 days but that's just from installing google now I think. Going to have to revert to my backup soon.

Last night I went to bed with 83%, woke up 7 hours later with the same 83%. This is madness I tell you. Madness.

Just my hunch, a dead vertical drop on the battery meter (you mentioned it had dropped straight from 65% to zero?) is just an error in the meter reading, and the "later" reading is the correction. I would think such an instantaneous (or near instantaneous) drop in actual voltage is improbable, if not impossible. But I'm just a dump civil engineer, not an electrical.
I've seen a vertical drop once. Others have reported seeing it repeatedly. In those cases, a factory reset seems to fix it, but flashing a ROM (with the usual data and cache wipes) would seem to do the same.

I've seen it twice now, across two different ROM/radio configs. I'll just chalk them up to random flukes and go about my merry way.

[Q] phone shuts down after battery goes from 40-50% to 0%

Today I had my AT&T One X at around 40% charge when I went to sleep. After getting up the phone had shut itself down and when I try to turn it on using the power switch nothing happens. I charged it then it starts charging from 0%. I am on stock 4.04 rom and have rooted the phone. This is the third time in a month that this has happened. I am attaching the battery curve that I got after today's incident. Please Help! Thank you very much for any help in advance.

Sounds like bad wakelocks, install Better Battery Stats to find out what is draining your battery.

I have installed betterbatterystats and will update with results next time it happens..

I too am having this problem. Though it started happening after my phone drained and wouldn't restart after charging (boot loop). After I fixed that, it's been dropping dead.
I'm on a stock rom with ElementalX 3.0 kernel. Was v2.0 when it initially started.
Any luck finding information? I still get about the same use out of it (sometimes). I'm thinking that maybe the battery's level is getting reported incorrectly?

This is a known bug, whatever the hell is causing it. Just about everyone has had this happen at least once.

How often are you having this problem. I have had this happen about 3 times in the last three weeks or so. Since my post last week, I haven't had it happen to me yet. I now have the betterbatterystats app installed and will update with results the next time I have battery drain.

It happens quite often. Happened today, then three days before that. I really don't have much on this phone either. After the initial bootloop I did a factory reset and didn't really add much.

This happened to me once on stock rom and kernel. I think it has something to do with the network trying repeatedly to connect and draining the battery. But the phone is asleep and not updating the battery percentage. When the phone finally awakes, it instantly updates the batteryfrom whatever it was before to 0. It seems to happen to people in the early morning.

There is a pretty sizable thread on this already.

I have contacted AT&T and HTC. Neither knows whats up. Went to CM 10 though and haven't seen the issue. Although, the last 2 weeks with CR Dev I didn't see the issue either. It used to happen every night.

Thought I remembered seeing a thread but couldn't find it via search.
I wonder if it's a sense based issue if you haven't seen it with CM 10. Though I didn't have any issues while using the stock kernel. -edit just read flar2's post about using stock and seeing the issue
Most likely something is draining while the phone is asleep and the battery doesn't update. You can see in my history details that when the phone wakes it jumps. Especially the ending death jump lol

I know if I have fast boot enabled and then it off, it'll drain around 10%. It only loses around 3 or 4 if the phone is shut down. I've never left it on overnight, but then again I am an avid task-killer

[Q] Way to find out why phone not deep sleeping?

I am running Skyfall with stock kernel. I was getting decent battery life, but today noticed that phone was awake for 2 of the 4 hours that it was off the charger. I have gsam and wake detector and wake detector shows nothing crazy that wakes it. I did disable location reporting, so maybe that might be pissing off some apps? I have not installed any new apps, only change was location reporting.
Thanks in advance.

Here is what I use,

Works great for helping to find those pesky apps.

Was it doing it before you installed gsam? I installed it and my battery went downhill. After I removed it battery got dramatically better.

It seemed like it. I installed it while I still had BBS running. While I was running GSAM my awake time was about 2.5 hours out of just under 4 hrs total and the phone was just in my pocket most of the time. After I removed it and rebooted the awake time stayed proportional to the time I was actually using it. Other than turning on WiFi optimization I can't think of anything else I did. So it may have been either one but I didn't have WiFi optimization on before I installed GSAM and my battery life was okay.

I have tried with and without gsam. I flashed the lastest firmware and radios and also the snapdragon app that monitors your use and is supposed to save on battery and today I got 3 hours of SOT, off charger for 16 hours and still have 55% left. And wake time back down to normal use. Im about to flash the latest Skyfall so we will see how things go on that build.

So started getting bad wake locks again. I looked and saw media server using a good portion. I have 0 media on my phone as I just stream. Anyone else seeing this issue?
