[HELP] Battery Drain, 35% drop in 10 hours

This has been plaguing my phone for a few months i can't even get 24 hours without it dieing. I can't figure out what the problem is and i have tried everything except a full wipe which i want to avoid.
Before i would get about 2 days with normal usage (few calls, browsing the net, msn, music and little bit of gaming)
Now when i unplug it at 7AM it is almost dead by 3PM (15%) but nothing has changed so i can figure out where the drain is coming from. I'm using Doc 9.6.6 (was on 9.1.4 and did a NO WIPE of 9.6.6 yesterday to see if i could get better battery) and SpeedMod K13C 500.
Everything that uses data is disabled or set to manual. Wifi is disabled, GPS is disabled, Bluetooth disabled. Google/Facebook sync is disabled. No Live Wallpaper, Email is set to NEVER, Fancy Widgets is set to NEVER. Reset the battery state in recovery numerous times, wiped cache etc.
Last night phone was at 60% when i woke up the phone was at 35% and that's only about 10 hours and after a FRESH shutdown and reboot. So nothing out of the ordinary like a game was running.
Whats Running after a fresh boot is in the pictures below, ending things like Tango and Galley, Facebook make no difference.
What is causing this massive idle drain?
If i need to do a full wipe is there a way to save my games saves? don't care for anything else just dont wanna start angry birds over again for a 3rd time.

You got 2 days before??
I've always only ever gotten max 12-14 hours out of my battery. Wifi off, bluetooth off, gps off, 3g on, background data & auto-sync on for: 2 gmail accounts + facebook (no auto refresh) + twitter (updates ever 30 mins) + whatsapp. BeejiveIM, GoSMS, Lookout, weatherbug elite widget (updates every 12 hours), agenda widget, NoLED on, and go launcher ex. Running stock rom JL2. Drains about 15% overnight (7 hours).
Not sure how you got 2 days before, but sounds about right to me that you get less than 24 hours from your battery.

Myself and many others get 2 days with light-moderate usage. I'm on 2 days 9 hrs and 10% left right now with 2 hrs 15 min screen time.
If you can't figure it out you might just have to bite the bullet and wipe it to see if that works.

yes i did try that, its annoying the hell outta me that it used to last 2 days but now its like this and thats with everything off.
I used to have a live wallpaper on all the time and yes that did drain the battery allot but i would still have about 30% after a full day of usage from a full change.
Now it dose not matter what i change if i live wallpaper or not its still dies about 3PM
any way to save my games says if i have to do a wipe?

That's awesome! I get 8% an hour drain on idle with 2 gmail accounts, and a few apps synching... with usage (bluetooth music, browsing, texting...) I have about 15% an hour drain.
Wiping, battery stats wipe, new roms, kernels, and modems don't fix anything... I guess we just have to accept that some units go through more battery than others!

If you're using Google Latitude service (configured via Maps), try signing out of it and see what it does for you. I've been suffering from excessive battery drain as well and after a lot of experimenting I've found out that using Latitude on Froyo ROMs (any Froyo) leads to phone not entering sleep mode properly for some reason and therefore draining battery a lot.
Nexus S users are experiencing this as well and I've even had confirmations from Desire users experiencing this, so this might be some bigger issue not related to SGS.

There's all the standard stuff running, gmail, swype, social hub, task manager, some other widgets, etc... There's no talk time on this run, it can burn it up pretty quick probably 20+% per hour.

Wow. I'm insanely envious of your 3days! and also, your display only sucks up 53%. Something is odd with my phone, my display usually takes about 98%.

Hm, do you have Google Latitude signed in on Google Maps?

No, no Latitude.
The display will suck up 90+% if you're using the phone alot since it burns battery much faster than idle or networks.

Interesting, I'm going to give it a go without Latitude on after I reflash stock JL2. My "Time on" for Display is usually something like 40mins or so when I check it at 98%

Idle drain seems to be what are most worried about.
Ok first fix permissions from cwmedia recovery in speedmod.
Then wipe cache and dalvik partitions, don't worry your phone will rebuild them.
Next I would try something if you want avoid a factory wipe.
Disable swype and clear app data then re-enable. Swype seems to have non wipe issues thru kies.
Now use OS monitor app to find apps which lurk in the background and then check their permissions, ones that can keep the phone awake are the culprits. Wipe their data or uninstall.
Facebook app sometimes doesn't shut down properly so watch that.
Also after a session I like to use clear mem level2 to stop Facebook or another app eating battery.
Finally what modem are you using? Jpy modem sucks for me at least. The latest jve from the gingerbread leaked rom is superb!
Hope this helps and good luck!
Stock JPY, Insanity SpeedMod OC-1200Mhz/UV, ext4, JVE gingerbread Modem,

Something I did a while ago seemed to help.
I ran down the battery till it switched off. Phone wouldn't power on. I plugged in the charger and powered on again. To my surprise the battery showed about 25%. Unplugged the charger then used it again till shutdown. Took about half an hour to do so, even though it was only connected to charger for a minute or so. Did that about 5 or more times till finally booting up with charger connected showed 0%.
Generally it not a good idea to boot with the charger connected as it stuffs up the battery stats or something, but I think in some cases it can help. Charged it to full and had no problems since.
Obviously this wont help if something in the background is killing the battery.

May be you have a task killer running in background and killing tasks that you shouldnt kill, by example any widget you have in your screen, it will cause that it will be reestarting and consuming CPU each certain time.

Remove TANGO !!! This soft was draining more than 25% overnight on my SGS (even if there's no service running and if it's not in task manager), After removing it, now my battery decreases 3-4% in 8h !

Funny Tango was the one thing that jumped out to me from the process list, but I don't have any experience with it myself. Shutting that off for a while is probably worth a shot.

This is my batterystats. "Taleanrop" is phonecalls or whatever the english term is.

[Q] sudden drop in battery life

I've got the 16gb nexus 7 (non 3g).
I've had it for less then a year and the battery life had been great. But starting over the last few days the battery is horrible. After a full charge over night my battery was down to 50% today. And that's with hardly any use. I used it for maybe an hour total and at least half of that time was just reading reddit.
I haven't changed any settings recently. This is all stock, no mods, not even rooted.
The battery usage right new says it's been 13 hours, and it's down to 48% and Android os accounts for 27% Followed by screen at 18% and WiFi at 9%. Those are the top 3 showing for battery usage.
Any suggestions as to what's going wrong it how to diagnose be fix it?
Thanks

Either your battery is bad or you have a stray process running somewhere.You might want to factory reset it, possibly even reflash your image.

Would the battery go bad that fast though? In my experience batteries usually gradually get worse. This went from losing a few percent of power to losing half power in the span of a day.
I might try the factory reset - just have to make sure everything is backed up. This tablet isn't rooted so i dont have titanium backup on it.

Doubtful it's the battery... my money is on a rogue app!!!
Hi, merkk...
It's possible, that as the previous poster suggests, some rogue app is 'eating' your battery.
The biggest consumer of power is the screen, so ensure you haven't got it set it maximum brightness... and ensure auto-brightness is enabled in settings.
Another thing you can check, is your WiFi setting... on my Nexus 7, I have 'Keep WiFi on during Sleep' set to 'Never'... it's not a setting that is easily found - it's buried in SETTINGS>>Wi-Fi>>overflow MENU (three dots, top right hand corner)>>ADVANCED>>Keep WiFi on during Sleep.
It also might be worth checking if the SYNCING of your respective accounts (Google, Twitter, etc.), haven't been inadvertently changed. Particularly the SYNCING of your Google account... which by default, SYNCs a lot of stuff and frequently. This will keep WiFi awake, and may cause battery drain. Go to SETTINGS>>ACCOUNTS>>GOOGLE and disable what you don't need to be SYNCed.
-----------------------------------------------------------------------------
It's unfortunate that your Nexus 7 isn't rooted, because there are a couple of excellent diagnostic apps available (GSam Battery Monitor and BetterBatteryStats) which provide more granular and finely detailed battery info/history than the standard Android battery info screen... and are useful for tracking down problematic apps that might be keeping the device unnecessarily awake ('wakelocks', etc.).
However, due to changes in Android 4.4 (KitKat), these apps now require root access to read and report battery stats info.
If your Nexus 7 is running any version of Android BEFORE 4.4 KitKat (and some haven't updated yet), then you don't need root to run these diagnostic apps.
-----------------------------------------------------------------------------
It's sometimes the case, with Android, that there will be occasional peculiarities with battery performance... and in my experience, it's almost always the case, it's due to something the user did... some app or widget installed. I'm currently experiencing similar battery issues on my Samsung Galaxy S3, but having run GSam for a couple of days, I think I have the culprit identified. If I can't eliminate the problem, I'll uninstall the app.
-----------------------------------------------------------------------------
Hope my ruminations are of some use.
Rgrds,
Ged.

Gedblake, thanks for the suggestions. For whatever reason, today it seems to be back to normal. The only thing i did last night was drain the batter to around 10%, turn it off, and let it charge while turned off.
Turned it back on today,used it for about 15 minutes or so playing a game. And now just about 5 hours after turning it on, it's down to 92% which is what I'd normally expect.
I'll try some of your suggestions if the problem re-occurs.

I noticed that my N7 (2012) has been draining quite a bit lately. Watching the battery stats, it seems Google Wallet was eating up some major battery. It was 2nd at 29% with the screen number 1 at 38%.
Not sure what the heck Google Wallet was doing, but I killed it and things seem to have stabilized.

battery drain after update?
For years I've had the same routine. I use my Nexus 7 all day for work, mostly notes. In between I play, (youtube, E-reader, etc). Every night I plug it in to charge and in the morning it's fully charged and ready to go. On Tues, I received the OTA update for 4.4.4 I noticed this morning that after a full night's charge, the battery only reports 50% charge. Is this the beginning of the end? What steps should I take from here? I recently bricked by GS3 so I depend on this thing now more then ever, any help would be sooooo appreciated.

I'd just restart it and let it charge again. I've updated mine a while ago and haven't had any issues.

I'm on a custom 4.4.2 ROM and I have had intermittent draining behavior as well.
Sync is off, location services off, I turn off wifi manually, and I always clear recents before I have my tablet sleep. I have greenify installed. I'm using better battery stats.
My issue seems to be similar, but I am also having battery percentages jump around.
Earlier today it went from 26% to 43% in the middle of me using it. Without charging. It frequently does this, both lesser and greater values reported. I've had my tablet shut down in the 30% range. I've had it shut itself off on 4%. I've had it drain all the way to 0% and then some before shutting down. I've had it turn itself off and when I power it back on the tablet is thinking it is at 25% or more.
I haven't been getting much more than an hour of screen time with my tablet lately. Clean fresh install of my ROM.
But I've never, until the last couple of days, had it go from a small percent to a large percent active during use. I took screenshots. I even started a thread to talk about it but nobody has responded yet.
Has anyone else ran into this behavior? Is it a sign of a soon to be dead battery?

mine got almost 30% drained on idle, airplane mode, screen off for 3 hours (tested on stock rom 4.4.3. GApps + Swiftkey + BBM + Facebook only)
my nexus 7 never lasted a day, only half a day max.
trying GSam app, hope it helps in knowing what's eating up batteries.

Heavy battery drain on each reboot

Each time I reboot my OPT, the battery level drops by at least 4-5%. I also find the phone takes pretty long to boot in general (around half a minute, if not more). With my Huawei Mate 7, rebooting was a matter of seconds, and the battery hardly lost 1% in the process. (The phone had other issues, though ...)
Who is experiencing the same? What could be the issue? Purely apps autostarting, or could it be something else? Note that I am rooted, running Xposed (with only 2 modules: GravityBox and VibrateMode) and on Boeffla Kernel beta15. I don't use Greenify and Amplify (anymore) and don't perform any heavy tasks on startup, except for loading some widgets (Google News & Weather, Google Calendar and Google Keep).

Same
Happens to me as well, using the same kernel, though i use kernel Auditor app too which starts on reboot, have greenify aswell .. battery drains by 4-5% on a reboot

Wow ... this is really such bulls**t ...
I adjusted multiple settings today that each needed a reboot. First I was at 30% battery, after the reboot I was suddenly at 20%. Note that before that, the indicated battery percentage had stayed at 30% for about two hours, despite being on mobile data with apps running in the background (not normal!) Then, I made a nother reboot. Immediately after that, the battery was at 17%, then suddenly dropped to 15% after several minutes, and several minutes later again to 11%.
Clearly this is a bug in how OOS calculates the battery percentage and something OnePlus needs to address in (one of) the next system update(s).
EDIT: LOL ... while I wrote this, my battery dropped to 7% ...

i can second this..., so if you dont want your battery to drop, dont reboot! LoL, kind pain in the *ss

Yeah, but you sometimes have to, like when updating an Xposed module or changing a setting that requries a reboot ... though I admit, none of this happens on a daily basis.
I tried soft reboots, but those seem to lead to issues with the phone recognizing the network carrier correctly ...
Hello, OnePlus, are you going to fix all of these annoying bugs in the next OOS update?

Today: percentage stuck at 44%, down to 41% after reboot, drop to 33% after several minutes. This is the most extreme case I have experienced yet ...

Whoa! I never had it THAT extreme ... I wonder what is wrong with the way the battery percentage is calculated. Seems like something with the calibration is way off in OOS.

Another observation: This doesn't seem to happen when the battery is freshly charged. I just did 2 reboots after charging to 100%, the first time it dropped to 99%, the second time to 97%. -> more evidence that the percentage isn't properly calculated while the phone is in use, hence these heavy drops from time to time vs. percentage staying the same for multiple hours.

Yep I'm seeing this too, mine even appeared to jump up after a reboot a couple of times

I am having the same issues, easily leading to 5-10% less battery after rebooting!
Also, my battery goes through the first 15 % or so very easily and then settles, there is clearly something wrong with the calibration!

There is clearly something very wrong with the battery calibration and/or the way OOS calculates the remaining battery percentage/time. I charged my phone to 100% percent over night, played a power-hungry 3D game on the train for 30 minutes, then flashed the latest Boeffla Kernel and did two reboots. I was at 78% after playing and at 64% after the second reboot (which seems "normal"), now my phone is idling at 64% since 2 hours.
Notice that the remaining time is shown as less than 2 hrs, and has been like that for 2 hrs ... this is highly unlikely. Also, what's the big gap there? The reboots surely didn't take half an hour ...

I also experienced this battery percentage stuck thing it stuck at 24%for few hours during that period my cellular data is on and sot is also half an hour during that time.
After that battery percentage suddenly drops to 20%.

Was experiencing the same, I tried calibrating my battery (Let it die, then charge it while it's off to 100%, run a battery calibration app, restart, charge it again to 100%), I used a 5V/1.8A LG adaptor (and not the original one, which seems to mess up touch sensitivity) and it seems to be fixed by now.

Battery goes insane

We all know the battery was perfect with M, we all know that since N battery drains way faster, but I've gotten used to that.. Instead of 5 SOT I got 3.5. Ok.
But now.. I hardly go past 2. Battery drains really fast, it's not even stable. Doze doesn't seem to work anymore, percentage drops each minute and a half, and now.. phone shuts down at 6% all the time. What should I do?
I'm a stock user.

You could install GSAM and see if it's an app causing the issue. You can also try turning bluetooth off completely for a day or two to see if that's a cause.
Worse case, you can do a full factory image re-flash. In my past experiences, most of the time, updating OS major versions never sat to well with my phone. I personally do a full factory flash-all after every major update.

Well that narrows it a little more than.
Actually, with a recent update, you can see now.
If you go to Enable More Stats, it will give you directions. I believe you need a file explorer, move one file to another location, and rename that file.

Software fault. The battery doesn't really charge fully, I've noticed that when my phone froze (literally) and it was on on 50%. I warm it up, says 1%.
After that my battery life is exactly half, which means that 1% is actually my 50% but the phone sees it as empty.

Check battery capacity with accubattery. Not completely accurate but it does give you a ballpark range. If the current capacity is way less than the specified spec, then you have a degraded battery

I agree with the Accubattery approach (or similar app) to measure the battery capacity. Several ppl have experienced degraded batteries.

Not unless you can get Huawei or Google to do it for free. I haven't seen any new genuine oem replacement batteries. They are either used or fakes that don't work right. Some don't even have a temp sensor. Accubattery shows 2876mAh for me and I get 4.5 to 5 hours sot on 6.0.1. Same as I ever got. After installing 7.1.1 with full wipe from factory image, same settings, same apps, same signal, same usage, I get 3-3.5 sot. On nougat my phone would intermittent turn off under 15%. Hasn't happened once since I rolled back to marshmallow 2 weeks ago. Either some people (like me) are using certain apps that consume battery without it showing on gsam and better battery stats, or nougat just uses more battery when the screen is on. I believe the latter.

I wouldn't think so based on that snapshot. I'd keep running the capacity test (documentation states accuracy is improved with time) and start looking very closely at individual services and apps for anomalies. If rooting is an option for you, wakelock and battery statistic tools are better able to return more accurate data than non-root apps. Absent any rogue apps or services, monitoring the capacity will give you a trend and likely answer your question about replacing the battery.

Ok, good to know.
Can you please follow this order of events?
1. The battery was as I've noted at the beginning of the post, drains fast and shuts down at 6%
2. I've had a factory reset.
3. I turned on the phone, clean and wiped, at 35%. It took me 1:29 hours to get from 35% to 7% [which is great!] but then at 6% it shut down again.
4. I turned it on right after, it showed 1%. It lasted for another 10 minutes of usage.
5. I charged it to 100%.
6. Then, when the screen is off, battery loses 2% per hour, and when I use it, it loses 1% every 3-4 minutes [which is great], BUT - sometimes it loses 2% at a time, say 80 to 78 and so on. I still don't know if the phone is gonna shut down at 6% or if it was already fixed.
Does that seem normal?

It doesn't seem normal to me. Neither the 6% shut down nor the increased battery drain. As I said, I had both issues to some degree, early shutdown, and much less screen on time. Since a switch to 6.0.1 fixed both issues I am lead to believe they are software problems, not hardware. Google responded on reddit that they are looking into the early shutdown issue about 10 days ago. Then there is also the sudden influx of bootloops of death after Nougat. My advice is to use Marshmallow until things become more stable.

You could go into accounts-Google and see if there are any syncing errors.. Facebook and Facebook Messenger are both known to cause big battery drains on Nougat. Gas Buddy used to be a problem as well but not sure if it still is. As another person suggested doing a full flash-all.bat clean install might fix your problem. Some people just go back to Marshmallow,

[Q] Weird Battery Drain + Indicator Problem

I'm not sure if it's more appropriate to post here
or on the custom ROM forum itself, but here's my battery issue:
Issue: Abnormally fast battery drain. My battery would
be fully charged, and almost immediately start draining until
it'd show 1% within 2 hrs. Screen would be off mostly (normal
use).
Been on a custom ROM since January 2017 (crDroid) and have had no problems with it since,
except 3 days ago, when the problem first appeared.
Things that are ON: LTE data (or Wi-fi), Auto apps update on
Google Play Store (never been problematic before), Location,
Things that are OFF: Bluetooth, ScreenCast, Caffeine
When I check Battery in Settings, the numbers don't add up.
I'd have battery indicator at 70% for example, but Screen,
Android System, all other apps would add up to only 7%. So
that's a whopping 23% unaccounted for.
But here's the weird thing: it drains fast until 1%, then at 1%,
the phone is supposed to initiate automatic shutdown like it has before.
When this issue cropped up, the phone keeps going for about 6 hours
or so before shutdown is started. Checking Kernel Adiutor occasionally,
I'd see a much slower decrease in voltage which probably reflects
more accurately the power drawdown situation.
Things I've done:
-clear cache (both through File Explorer and TWRP Recovery)
-clear batterystats.bin
-calibrate battery after full charge/discharge (via Root Essentials,
which basically does the same thing as manually deleting batterystat.bin,
if I'm not mistaken)
-Resetting App Preferences via Setting/Battery
None of the above has worked. Any idea what might be wrong?
My device is a Zuk Z1, with a 4100mAh battery. It usually lasts me more
than a day on normal use, but as the attached pic shows, it's at 96%
yet without having used any apps yet, has only 2 hrs of juice left.
I've tried reflashing my ROM, wiping everything including formatting data
yet nothing has worked.
I'm a light user, as I don't play games or watch videos on my phone.
Neither do I use graphics-intensive apps. I haven't used processor-intensive apps
that require constant GPS (like Google Maps, Waze) since then.

Battery issue, just replace it

I guess you have bad habit of charging your phone when it reaches to 5-6%? Am I right? If not and you charge your phone in a healthy basis, then I guess change the ROM or re-flash it. It might work. Or else replace the battery.
