[Q] My phone keeps dying!

In the last week or so I have picked up my phone three times and it has been dead.
The power button doesn't turn it on again.
I have to take the battery out and then restart it.
I'm running a rooted 2.35 JVT.
I have nothing untoward running ...

Could it be a dead battery?
otherwise, tried to wipe and (re)flash a rom?

The battery is fine, and the ROM has been there for well over a year with no problems.

Finding the root cause of battery drain...

There are a number of standard steps to run through to find the root cause of battery problems, assuming the drain is caused by the OS or apps and not actually due to a physically failing battery.
I have been tracking a few battery issues myself recently and this is what I have learned from doing some reading on XDA:
There are two free apps on the app market that are typically used to diagnose battery problems:
Better Battery Stats
CPU Spy
I would recommend installing both apps. The third place to look is in the battery details in the system settings...sorry I can't remember what they look like on Gingerbread because upgraded to Jelly Bean a couple months ago, though I do remember there was less information in the stock battery info on Gingerbread.
IF you are not, indeed dealing with a physically dead battery, then the root of your battery drain is most likely caused by a background process or app that is keeping the processor in a partially active state even though the screen is turned off and one would assume the phone should not be using any power.
Android OS will automatically change the running speed of the processor in the phone based on the demand of the system. If only a few background tasks are running and updating information the speed might be 200 or 400 Mhz. If the system is running full out servicing a graphic intensive game the processor will likely be running at the full 1000 MHz speed. The speed of the processor will directly effect the battery drain.
The expectation is that when we turn the display off (not power down, just put the phone to sleep) the processor should need fewer resources and slow down, tending towards a state known as "Deep Sleep". At this point the processor us using very minimal amounts of power. Any app or process that is active in the background will prevent the processor from getting to Deep Sleep. The CPU spy app will allow you to check how much time the phone runs at various speeds. Once you install it and run it, then reset the timers in the menu and turn your screen off for about 10 or 15 minutes. Then 'refresh' the timers. Normally, you should see most of the time accumulated in Deep Sleep. There are standard background tasks such as syncing with the cell tower, updating time, mail, checking alarms etc. That will engage the processor momentarily but they should be relatively short compared to the deep sleep time. In my case, an errand process was keeping my phone at 100Mhz constantly preventing deep sleep.
Once you know that something is keeping the phone awake in the background, you can use Better Battery Stats to narrow down which process or app it is the cause. This app allows you to track the individual processes that are consuming the most time and preventing 'wakelocks'. Wakelocks are essentially an app preventing the sleep state and are very well explained in this post: http://forum.xda-developers.com/showthread.php?t=1827676
The battery info in the system settings can also be used to give clues though again, I can't remember how much detail was included in Gingerbread..
If your problem only started happening recently, then it could be a new app that you installed recently, a feature or setting you changed recently or possibly a recent update to an app that was already installed. Try to think back at any recent events that could have triggered a change in the system.
Common problem apps I have read about are:
- Facebook - seems to be bad at using lots of background processor time. (Don't run this app but reading several posts shows its a processor hog)
- Google Apps that sync - Gmail, Chrome (syncs browser history, tabs etc.), Google location stats.
The wakelocks link goes into a great deal of detail and is hugely valuable in nailing your issue down.
Good Luck, let use know via a post if you find the root cause...

Sorry, maybe I wasn't clear about it being 'dead'.
The battery is 100% or thereabouts, no problems ever with the battery.
The phone looked as though it was turned off, but wouldn't turn on again with the power button.
I have to take the battery out and put it back again, then it starts on the button.
I've cleaned the contacts, and it still happened.

To me, it sounds more like a rogue process messing up power managing or response, but it's hard to tell what it could actually be.
For instance, you might come a cross a game that leaves your phone locked in max cpu frequency, draining the battery without explanation.
If it was me, I'd re-flash the rom from Odin, perhaps with an sd card wipe too.

Unusual battery drain

Hi,
I know there are many topics on the subject but I didn't find any solution to my problem.
So, since a couple weeks, about when I moved from Europe to the US, my phone drains significantly more battery than before. This has apparently nothing to do with screen brightness, wifi or cell data, since it occurs even in airplane mode during the night. I used to lose about 1-2% during a night, but now it's at least 15%.
You can find a couple screenshots from BetterBatteryStats there (sorry for broken link, it does not work otherwise): n.ethz.ch/~bauera/uploads/Screenshots/
So as I noticed, there are a couple wakelocks but nothing that could explain this large drain. Any idea what could be the reason and how to fix it?
FYI I am using the stock rom 23.4.A.1.232 with Android 5.1.1. Phone model is D5803. The OS was rooted directly when I got the phone in October 2015 and as I said, I did not have any battery problems until recently.
Thanks for your help!
Alex

that's the lollipop battery drain bug on mobile radio, marshmallow should have fix this

Thank you for your reply. However are you sure of that? The bug you are mentioning is apparently linked with mobile data, which I haven't even turned on since a couple reboots at least. Moreover, the battery stats for the night (from the built-in battery menu) show that the mobile network was fully off during that time (airplane mode).

Thanks for the suggestion! Unfortunately it didn't work in my case, I still lose about 2%/h in airplane mode and screen off.

BBS - Better Battery Stats is your freind. There's also lots of tips in the thread on how to limit most of the common wakelocks.
There are several services in the new Play Services that are keeping your phone awake. With the introduction of wearable bluetooth there are new fitness services that are looking for your wearable devices constantly, disable them and your battery gets better. Obviously if you use fitness bands/trackers then this fix is not for you.
If you have a rooted phone download Disableservice from the playstore, it's a lot easier to use than Xprivacy and you don't need to install Xposed.
Once it's installed, open the system tab, open Google Play Services, then untick (disable) the following:
ConfigFetchService
FitnessSyncAdapterService
GoogleLocationManagerService
GoogleLocationService
NetworkLocationService
ProximitySettingInjectorService
UserPresenceService
WearableControlService
WearableService
WearableSyncService
then reboot your phone.
Disabling these from running should have no impact on your phone, it doesn't for me, and will give you 10-15% more battery life.

Solved Battery drain for Me
I was also suffering from the same battery drain issue, but after doing a lot of research on this forum, few tricks mentioned here worked for me.
It had been 6 days I bought the phone, so was very disappointed by battery life, did upgrade from PC to Lollipop, but still the problem persisted and even worse. So I decided to go back to Kitkat and followed steps here: http://forum.xda-developers.com/z3-c...d5833-t2906706
After downgrade the battery got somewhat better not satisfactory, so I followed the trick of complete drain upto 0% and charge to 100% (switchded off) after reading posts: http://forum.xda-developers.com/z3-c...5#post59797105 by Sydr08 #182
and cache clearing trick after 0% to 100% charge http://forum.xda-developers.com/z3-c...harge-t3207737
After doing 100% charge I turned ON with vol+ pressed but phone did not respond (I guessed that it didn't worked, so switched ON normally) but after booting I found few settings to be reset so I guess it worked
So finally this trick seems to work for me, now the drain has slowed down to a lot extent. I have used phone regularly (calls, games, whatsapp, Music etc), the battery has dropped to 76% in around 8 hrs ( without stamina mode ) just expecting it to last for two days, and more than that with satmina mode.
Firmware: .77 (India)
Model: D5833

Hi Aakm,
As you said, the tricks mentioned so far on this thread were not really effective, at least for me as well. I could live with that 25-30% left at the end of the day (it is still much better than my old Samsung GS2), but I would be glad to be back to the 2-3 days of moderate use as I had during my first months of ownership.
So I'll try this out over the next days and hopefully it will work, thanks for suggesting! It sounds a bit like magic to me but let's give it a try
Best regards,
Alex

Unfortunately the full drain+charge did not change anything for me. I did not try to downgrade to Kitkat but as I've had good battery on Lollipop for several months, I doubt it would help.
Anyway thanks for your help, but I guess I'll simply wait until Android M comes out and take the opportunity for a full factory reset, hoping it will solve the issue.

Please guys mark the star on the bug report, the more people agree, higher will be the chance that google decide that it's time to fix it

Odd battery life

Hello,
Since the purchase of my phone XZ1 Compact (G8441), I've been experiencing barely acceptable battery life. This is especially frustrating since I bought this phone having heard that it can last easily 2-3 days, but this is not the case for me (discharging about 4%h on average or 2.5%h with screen off on either wifi or mobile data, with various configurations outside/home/office, i.e. in practice never usable more than a day).
According to *#*#SERVICE#*#*, the battery life is still good (2704 mAh). The issue I am experiencing is most likely due to an unknown software and/or hardware failure leading to lots of wakelocks that prevent the phone from "sleeping"/"dozing" correctly.
I know that MANY users worldwide are experiencing this and Sony never gave an answer to this, according to e.g. the following threads:
https://talk.sonymobile.com/t5/Xper...-drain-after-update-47-1-A-12-235/m-p/1337029
https://talk.sonymobile.com/t5/Xper...-drain-after-47-1-A-12-205-update/m-p/1328053
https://forum.xda-developers.com/xperia-xz1-compact/help/battery-life-bit-odd-t3688342/page8
https://talk.sonymobile.com/t5/Xperia-XZ1-Compact/High-battery-drain/m-p/1326474 https://talk.sonymobile.com/t5/Xper...-drain-after-update-47-1-A-12-270/m-p/1340671 https://talk.sonymobile.com/t5/Xper...pie-battery-drain-CPU-idling-high/m-p/1354891
and many others
In my case the items "NlpWakeLock" and "RILJ_ACK_WL" activate both up to thousands of times every hour. No relevant information could be found about this in the web lookups I've done, and I am not sure this is related to the issue I'm facing. I joined a log of today's better battery stats with a pathetic 1h20 of SOT and 65% discharge, a huge count of wakelocks except when I was listening to music, and an apparent faster discharge with the idle phone than when actually used.
The phone is running the latest downloadable Sony firmware 47.2.A.10.107.
Of course, factory reset was tried with no amelioration and I tried to contact directly Sony which have basically no willingness to help or investigate.
Anyone would have a clue about this?
Thanks,
Alexandre

Do you use Google Now (google assistant) - NlpWakeLock
If not, disable it and see what happens.
This little phone I have for battery life and for banking/authenticator/etc. Not for work. So I have disabled most things I do not need (adb uninstall) - so the battery is quite good on standby.

Thanks for the reply. Unfortunately, as I don't use GoogleNow, the whole Google App is already disabled...
I'll try and do some adb uninstall and will keep you posted

Looking at the bbs stats. The first thing I noticed is that your wifi is on all the time. Try turning it to only when awake and disable the wifi scanning in locatin settings.
RIL wakelocks are on because you have poor signal, it's the number of handhakes your phone does with the local cell tower and if you have bad signal, it gets higher.
Some providers offer home 4g boosters for your home or 'calls over wifi', either of these would reduce your battery usage.

My phone has been flawless (2-3 days on battery when I don't play games) but suddenly it started behaving like described in the original post.
It has 1 day life now and I haven't found the reason for this change. I have removed all recently installed apps, removed all unnecessary apps (including Facebook app), disabled running in background for some (like Messenger), there was no firmware update at that time. Still something is eating up the battery. SmartPanel tool shows that 58% of battery is Unaccounted (next is display and Google Services). I have not done the factory reset yet because I need fully configured phone right now.

Faster battery drain after OTA update to 9.1.0.252 on Huawei P10 VTRL-L29

After updating to 9.1.0.252 I noticed faster battery drain. Did any of you experience the same behavior? I'm thinking to go back to 9.0.1.
Thanks

I feel the same

Don't forget that our device/battery is getting older with every update?.
It might look like new but mine is already 2 years in use.

I noticed faster battery drain on my ltr-09 as well. All is fine now. I noticed when i first upgraded location was turning on alot almost like it was learning when to turn on. Then it levelled out. Example opening google now at first it always turned on my gps now it doesnt. When i was on 9.01 i left my phone on battery saving for gps. You cant on 9.1 and i have seen alot of apps that used to be good with battery saving location now going for full with gps. Big bttery drain. Those were the differences i found. What I believe solved my battery drain was actually my battery getting all screwed up. I had this happen when i would switch roms and my battery stats would get all messed up. I solved it before and solved it this time with my p10 by running the thing right dead. Then pluging it in overnight with it turned off (no fast charging) Then I did it again the next night drained to dead , plug in charge with off ( no supercharging) and my battery life is better again. Hope this helps. EDIT After a few days of testing i still felt the battery was better but battery life still wasnt right. I did a factory installed minimal apps. Battery life was good until play store updated carrier services. I uninstalled updates to carrier services, disabled auto update. Then i actually disabled carrier services completely. Battery seems good now. From what i read carrier services is for next gen texting. Saw online others were having issues with this update.

Wrong, batteries get older with time and charging cycles. Updates have nothing to do with it and if you notice a drain right after one - it has nothing to do with the condition of the battery, it's the update's fault.

updates are huawei's way to convince you to buy a new phone
first they borked the camera, now they are messing with battery

I managed to improve battery life a little bit by disabling apps running in background and disabling unnecessary location permissions for several apps like @bigshowjh said. Like @bigshowjh said I found apps resetting their permission or settings after update. Still the battery life is not like it was before updating with the same usage behavior.

I have ran a couple of days with very good battery life. 11.5 hrs with 62 percent left. Seems like it used to be with Oreo. Overview of all I did was as follows. Clear cache partition, factory reset . Uninstalled Google Chrome (used Firefox instead) set carrier service to factory in apps three dots advanced. Disabled automatic update of carrier services in play store, then in settings apps disabled carrier services completely. Went through and disabled network access to every app that doesn't need it. I don't use Facebook or Facebook Messenger apps. I use them through my browser. Oddly chome on pie is a battery killer as well. I'm very satisfied with proformance of my P10 again.

My GPS is pretty much always off (unless I really need it) and the battery level still goes down by 9% during the night. It used to be 3-4%.
I cannot find carrier service anywhere.
In my case I can't see power hungry apps in the stats, standby process uses the most energy.

Settings, apps, apps again, select three dots in upper right, select show system processes. You will find it there it's a little hidden lol.

Still no carrier services for Play Store.

Wifi battery drain on new note 9 (exynos) with no new apps installed after pie update

I got a new note 9 for black Friday and updated it to the latest version of Pie. However after this I've noticed the battery seems to drain 1% every 5-10mins with wifi enabled on idle (even in flight mode/no-sim). I haven't switched over from my old phone yet so don't really have any new apps installed. I've tried a factory reset and clearing cache but still seems to be the same. The drain is even worse when actually using the phone or web browsing. With wifi turned off, idle time seems good(1% drain in 10hrs).
Anyone else experienced the same or know how I can find out what is causing this? I've spelt the last hour or so going through every thread, and here's what I've tried:
-Disabling background data usage on most apps
-Uninstalling non-essential bloat via adb
-Disabling auto account syncs
-Using wifi power saver & safe mode
-Using medium power saver mode

You probably flashed a messed firmware, why don't you try One UI 2.0?
They say battery is awesome there.
Mainly, when using WiFi, everything in phone starts running in background, check updates, download updates, ...
If you only want Pie, Uninstall Google Play Services, Join their beta program, and update to latest beta (or you can do it manually).

I've haven't used any custom firmware yet, just ota updates for now. One UI 2.0's beta program isn't available in my country yet, though the stable version should be here next month I hear. Thanks, will try the google play beta program. I've also been reading about battery historian, may give it a try to see if I can pinpoint what is actually causing the issue if that doesn't work.
