Hi all,
Hope someone can help or this can be of help to someone.
I have a UK Galaxy S 16GB on Vodafone. Came with Eclair XXJF3. I have flashed it several time to various versions of Froyo including XXJPK, XXJPO and most recently BUJP7 (as it is the official Vodafone ROM). All using Odin.
Like most I seem to have had battery drain issues, very rarely getting over 12 hours of non use.
I decided to flash one last time to a clean build of BUJP7. I first reverted back to Eclair with repartition and then to BUJP7 without repartition. OK so far. I installed OCLF and set Minifree to Strict and Scheduler to Deadline with tweaks. I also installed Battery Graph and set up my Google account.
I left it like this and noticed I was getting excellent battery life. Infact over night I was getting anything form 9 hours with NO (0%-1%) battery drain and about 7% battery drain. Which is excellent.
I then decided to setup my work Exchange email account. And BAM, thats the day the laughter died. Battery drain was back to the level other have been reporting, about 10% per hour. I have messed about with the email collection frequencysettings, using Push, Pull every hour and even set it to None, and still getting battery drain. If I remove the account completely, the battery drain poroblem vanishes.
I have also tried this with a regular POP and IMap account and it seems to have the same effect as having Exchange setup.
I apologize if this has been answered else where but there is a sea of threads about battery drain and none seem to focus on the fact that it could be email accounts that are causing it. I know that my battery stats are shot due to RFS (repeated flashing syndrome, is that illegal?) and so maybe I need to do a complete factory reset, wipe my internal SD card and see how that goes, but it just seems to coincidental that the email accounts setup and battery drain occur at the same time.
Thanks in advance to anyone who supports this thread and hope I have provided some insight into (another) cause of battery drain or at least given some food for thought.

Someone made a thread saying that if you set it to push the battery drain isnt as bad as when its set to poll every time frame.
I think that may have been my issue (the first thing i setup was email and the battery was dead after a few a hours). Also flashed back to JM1 as i couldnt work it out.
Might try it again, bit annoyed with all of this massive drain...
BTW, the thread title should be Froyo EMAIL battery drain issues. DOH! Me and my sausage fingers.
Thanks for the reply. I have tried Push and Pull email settings. And had it set to never pick up email. Seems like just having the email account set up is enough to drain the battery.
Thats bloody annoying, im not really sure what else to suggest? You could try an alternative client like K-9 Mail, I had to use that on Eclair as the Samsung client wouldnt work with my hotmail account.
I was thinking of trying another Froyo ROM tonight, but not sure if i should now
Hi all,
After noticing my battery was draining quickly, and then after reading this thread , I installed Android System Info to see what was draining my battery so fast. I notice that whenever I would turn on WiFi, the phone will never go to sleep , regardless of what I set the WiFi sleep policy to. After turning off WiFi, the battery still drains heavily.
The WiFi will shut off after 15mins (if you set it to "When screen turns off" or "never when plugged in"). However it seems to keep the CPU on causing it to drain down the battery.
It would seem that whenever WiFi is enabled, the Android system process creates a partial wakelock that does not go away even if you turn off WiFi, and even when the WiFi shuts off as per the WiFi sleep policy. The only way to resolve this is by powering off or rebooting the phone.
You can verify this in Android System Info by going into Battery-History-Other Usage-Partial Wake usage to see how much time the "Android System" process holding a partial wake.
I even did a factory reset on the device; and it is still happening so it doesn't appear to be any app that caused the issue. As I said, it works fine as long as I don't enable WiFi.
I already know of two users having this issue, but I'm wondering if folks having battery problems are going through this as well. Is anyone else having similar issues after using WiFi? I'm hoping someone will be able to identify what exactly is putting the wakelock on and we'll be able to find a fix for it. Other than not using WiFi at all or rebooting the phone after using Wifi.
Does someone know if there is a utility to drill down and see which process would be causing the wakelock? "Android System" doesn't give me any more details.
Any help would be greatly appreciated.
btw I'm not using any battery savers or task killers.
Update...i have the wifi sleep policy set to "never". Also have the network time sync disabled. I am no longer getting alot of battery drain from the Android System partial wakelock.
However, this means WiFi is on all the time....which burns up the battery as well.
Do you think this is a Samsung bug or Android that won't properly let the device sleep when the WiFi sleep policy is set to anything but Never?
Hoping someone at XDA can figure this one out.
I wonder the same thing...I lose about 20% during the night when the phone is not used for about 7 hrs. Not sure if that's normal or not

Set the WiFi sleep policy to "Never" and reboot the phone. Shut WiFi off if possible overnight. You should notice a big improvement with battery life.
Devs - is there any way to see what is wakelocking the Android System process?
The WiFi sleep policy seems to be broke on the Captivate so hoping someone that really knows these things can help out to identify what is going on.
I've had wifi sleep policy to "never" since I got it. Turning off wifi when going to sleep will slow down battery drain when the phone is not in use all night?

It should. Also setting the network to gsm only will use less battery. We need to find a way to see what process is holding that lock. Any dev experts out there please chime in.

That is anything but normal unless you live where your cell signal is very weak. I see about 1% lose every 60- 90 minutes when idle. 10-12% when browsing or reading xda. Dont do heavy gaming do not sure what you should see there. Weak cell signal will kill battery life as can other factors.
I do have a weak cell signal at my house. I'll have to ck it in idle mode in my office, where I have a good signal to see if that makes a difference
On the other hand I just recently installed beautiful widgets and use it's live wallpaper. Also lookout..I'm thinking that could be a battery hog
I'm experiancing the exact issue in the op.
Android System is holding a partial wake lock of about 30-40%
My battery drains 40% overnight.
Are there any fixes for this?
The problem for me was definitely the stock email app continuously polling my Exchange server, killing the battery and my data plan. I resolved it by removing the Exchange server from the stock mail app, and by using Nitrodesk's excellent Touchdown app for mail instead. Touchdown isn't free but it's very good. And now my battery performance is back where to it was prior to the Gingerbread update.
Thanks, Google, for carefully testing this update before releasing it on the unsuspecting public (NOT). You caused a lot of grief for a lot of people.

I may be wrong, but isn't the default email app from Samsung?
Though, you are correct. I setup my work exchange on it as well and it is definitely a killer. Lately I haven't really been giving a **** and just charge my phone every night. However, I might look into this Touchdown app now.

for the stock email app you can configure the sync schedule so it doesn't continuously poll your exchange server overnight. i have my sync schedule set to push when i normally wake up and an hour after i get off of work. during off peak hours its set to manually update.

how did you set this up??
Somewhere earlier this year I started getting a 20% overnight battery drain. On a few nights it didn't drain, but its pretty consistent. I have tried everything listed on this forum..This drain is definitely not caused by any standard settings. I am really hoping somebody with insight into Oreo might have something new I could try. I know xda user Digisteve is going to showup and suggest more things, and that is also not going to work.
Things I've tried.
- using root to disable logd. (saw this as a process in BBS) Still drained.
- Disabling auto-sync of all accounts. Still drained.
- Turning on stamina mode at night. Still drained.
- Removed google play store, google play services framework, and all google aps - and replaced with alternative China app store. - Still drained. Not a play services problem.
- Turning off wifi, all wifi scanning, notifications of wifi networks etc. Still drained.
- Turning off mobile data and wifi - no connectivity at all. Still drained.
- Turned of location in all possible device settings,. Still drained.
- Rooted the device with Janjan method/kernal. Still drained.
- Flashed different regions. Including (Taiwan, my region, Malaysia, Germany, Swiss, HK). Still drained.
- Tried firmware verions , 179 , 205, 235, 270
- Deleting 3rd party apps. Still drained.
- Installing Gsam - checking for consuming apps. No apps listed as cause of the drain.
- Installed greenify. Tried as standard, non-rooted with adb permissions, and fully rooted. Still drained.
- Disabling various packages related to 'carrier services', qualcomm and rcs. Still drained.
- Debloated to the point that the phone had no google apps, no Xperia apps and removed tons of other apps, camera bloat, anon data, etc, all removed. Still drained.
- All built in apps replaced with a 3rd party app, including, sms, contacts, email, keyboard. Still drained.
- Installed Linage OS 15.1 Beta 5. Still drained.
- switched from 3G only to LTE only. both drained equally.. though I have worse single with LTE in my area.
I am hoping there is a better solution than throwing the phone away. Because I am pretty much at that point now. I have spent probably well over 120 hours trying to fix this, and I can't. Its at the point where I need to move on to a new device rather than waste more time.... but there are no small devices on the market now, and also no more classic xperia style devices on the market. Sony does not make the executive, classic 'Xperia' style I fell in love with anymore. I don't do round, heavy, huge phones. Very sad.
UPDATE - AUGUST 14
Now running the latest Customized German 270 firmware.
Still draining 20% per night. Check out the screen shots - clear to see I have almost no apps. No process can be seen as a battery hog in both Gsam and BBS. However Gsam screenshot shows evidence of CPU usage.
UPDATE - SEPTEMBER 13 - FOUND THE PROBLEM
Considering almost nobody had my issue, I assumed my phone must be a dud. Late August I bought a second XZ1 compact. The new phone worked for 1 day, and on the second day drained battery at 15% per night idle drain. Previously I had only tested the sim card by switching 3g,4g and disable mobile data, but never actually removing the sim from the phone. Last 2 nights I replaced my old sim with my gf sim of a different carrier. In the morning I had 99% battery remaining. No Drain!
I then downloaded an app these measures signal strength, and turns out where I sleep at night, there is is less reception. Its not noticeable just looking at the standard signal strength on your home screen, you need to check the more detailed strength in decibel millimps /dbm. I can still get good signal in most areas of my house, but the phone is having to use more power to keep the signal good. I can now reproduce the battery drain on demand. If I sleep with the phone near my bed, I get drain. But if I keep the phone in the living room, no drain. I found that connecting to wifi not a factor, since even if you use wifi for data, the phone was still holding open a connection the the cell tower.
This problem took me months, countless hours, and the expense of buying a completely new phone!!! Now I have 2 XZ1 compacts....arg.... but so happy its solved.
The important point is that if testing sim, good signal, or disabling mobile data, changing 3g 4g isn't enough. Your phone is using more power to maintain good signal.
Thank you to everyone who spend time trying to help me, digestive, proflyer, etc. Thank you guys.
At this point, I think it's highly likely you got yourself a lemon. Since you've already rooted the phone, warranty service is out of the question.
It boils down to two options:
1. Pay for a board replacement.
2. Try your luck with a brand new XZ1C. Buy it online so that you'll get the 7 days return perk (some online stores offer 10 days), keep it wrapped in its original packaging, handle with extreme care, and use it normally for a few days before your return window runs out. If you no longer get drains, congrats, and welcome to the club. If not, accept your fate, return it for a full refund, and give up on the XZ1C - understand that you weren't meant for each other and move on.
I had the same issue. Check this thread. Try that and report back.
https://forum.xda-developers.com/xp...ormal-battery-consumption-wifi-t3740495/page3
I know what you feel. I had this too, but mine went away and I only very rarely have this drain. But mine was always on Wifi. With Wifi off = no drain reported... never.
I investigated it for weeks without coming to a conclusion.
If you can, replace the phone with warranty. Worth a try. Right now in my opinion you have a hardware faulty device.
But i would say to wait for android 9. In my opinion it wont take ages to come. It will much likely come this year.

He still has drain even with WIfi Off, so that not the problem.
The only other thing I could suggest is having the battery replaced at a local repair shop. If you got a lemon battery but an otherwise fine phone, that could help.
How about remove your SIM card with wifi on for over night? Do you still experience the drain?

UPDATE - AUGUST 11
ONE WORK AROUND. If I reboot the phone, then unlock it so "android is starting" screen is complete. Then lock the phone, without doing anything else - The battery does not drain overnight. In light of this, what could be the solution? I know an app sounds logical, but I arlready checking my 3rd party apps, and none of them were the probably, an no battery app has ever listed an app as a drain.
Any technical or Dev person go any idea what that symptom points towards?

This does indeed sound like an app or a service gets stuck in an awkward way. You indicated in your first post that you use better battery stats, do you mind posting screenshots of the top of the summary, kernel wakelocks and partial wakelocks page (showing keeping awake services) as well as the bottom of the cpu states page (showing deep sleep time) "since unplugged" after a few hours of drain?
I have attached corresponding screenshots here for my xz1c (after more than 24 hours unplugged) as a reference (I have play services enabled and syncing both gmail and contacts and so on, no root though).

That doesnt make too much sense. Test it for at least one week before coming to conclusions.
Try this and let me know if it works
I had exactly the same issue
What i did (now magicaly works)
I did not have too many time so what I did was simple and I got a cheap replacement phone in the meantime
It seems to be beyond everything we tried
I conected the phone to the pc and did the fix with xperia companion, then I realized that everything was working as soon as I started to install the apps the problem came back, I installed a launcher (nova) and use it, drained the battery útil reach zero and fully charge it, then everything was working... Back to normal... I don't know how the issue was solved but hope it works for you
Sorry about my bad english xD

The screenshots from BBS look pretty normal, the GSMBattery shots show issues with Google Play Services, so I'm guessing they were taken at different times. But there's nothing jumps out of the stats that looks out of the ordinary. Have you run the phone in safe mode overnight to see if you get the same drain? I think you may just have a duff battery, no one else has reported this sort of power loss before.
$40 down the repair shop to get a new battery is going to be a whole lot cheaper than a new phone.

Thanks didgetsteve. your probably right.... The GSAM and BBS stats were taken right after each other, maybe a gap of 2 mins. Play Services wasnt the issue though, as I tried my phone google free, and it still drained.

I agree with didgesteve, nothing jumps out by just looking at bbs (I am not familiar with gsam, so I cannot comment so much on that).
Before replacing the battery, I would probably make sure that it is not radio/network related. I have noticed that my phone draws significantly different amount of battery (in deep sleep mode) depending on the mobile network. This is mostly independent on whether mobile data is on or off.
Could you turn on airplane mode for an hour or two and verify that it is not the radio chip that is causing your drain? (If that is the cause, I am not sure if you can do anything about it apart from switching carriers or experimenting with 2g/3g/4g settings, but it might be worth knowing)

I also had the drain that Dean has. But mine wasnt so agressive, I mean, some days it was there draining 30% battery over my sleep time (8hrs) and sometime it just behaved normally draining max 3% over sleep time. But still from time to time the drain come back wich is annoying as I cant let my phone with 30% battery left when im going to sleep, afraid the battery will be dead and the alarm wont wacke me up lol.
On my extensive tests, the drain only happened with wifi, but even deactivating all wifi related process (backups, syncs etc) the drain was sometimes there. Wifi wasnt the culprit with Dean, but on my tests: Wifi On = Sometimes big drain , Wifi Off = never drain.
I never managed to find the culprit of this damn drain and Im a software tester. Gsam did not show anything unusual at all. It was like Deans screenshot.
We discussed about this issue a lot here (https://forum.xda-developers.com/xperia-xz1-compact/help/battery-life-bit-odd-t3688342/page8) but till this day we dont know whats triggering it.
Im curious how the phone will behave on this issue with android P.
@ergoen @Didgesteve . Can you guys comment on my 4th screen shot, the one where you can see the CPU usage. Does anything strike you as odd in that pic? TThe CPU util looks high... it is normal?
i dont see nothing odd there

I'm sorry, but I don't think I have the knowledge to judge that. I would expect CPU usage to be low in deep sleep mode, but since the CPU is mostly sleeping, I guess any requested usage will queue up in a way that might look odd, so what you are seeing might be normal (but again, I don't actually know). I also believe that CPU power consumption is mostly related to the frequency state it is in, so deep sleep should mean low consumption (independent on cpu util %).
As I indicated in my previous post, I would sooner blame the radio chip or the battery than the CPU given your BBS screenshots.

Bro, Samsung is even worse when it comes to battery drain. Check out linus tech tips vid from a few days ago https://www.youtube.com/watch?v=n46s_iF_IV4&t=324s
My wifes side of the family all have Samsungs.... they are totally ****. The OS is bloated, ugly, laggy despite monster specs huge ram, snap 845, and battery nightmares on brand new phones exactly like in Linus's video. And there is a stupid "BIXBY BUTTON" on the phone which is a total nightmare. if your with Samsung, BIXBY will the with you, following you forever.
In other news, I replaced my Taiwan XZ1 compact with an Australian XZ1 Compact, and my drain is gone. I drained 2% last night.
There are so many build differences with the Taiwan and Australian build of the phone. Bigger microphone holes, slightly different proximity sensor design, and the plastic back is a rough matt black/gray in the AU versions, the TW version was a smoother shiny midnight black with a silver sparkle in the sun. The biggest difference was of course the battery drain.
Hello!
I've owned a N960F for about 2 months now and recently I'm dealing with extremely high screen off battery drain. Looking at the stats offered by the battery tab in device care I am unable to pinpoint the cause.
Furthermore, accubattery shows very low deep sleep time. Last night it managed to achieve an incredible amount of deep sleep of 0 minutes and drain 12% in just 5h 20 minutes of screen off time.
Screen on time is not a problem, while using the phone the battery usage is normal and I am pleased by it's performance, but it is greatly affected by the screen of consumption.
Does anyone have an idea what might be causing the device to not enter deep sleep mode? Or how to find out what the problem could be that makes it use up so much juice?
Thanks in advance!
Screenshots (the accubattery is from yesterday, while the device care one I screenshot just now):

Difficult to tell, possibility is an app in the background preventing deep sleep.
When you use device care and then select battery, followed by settings you get a further screen of options, you may be aware of this.
I have used these settings, it might help.
An alternative approach is to uninstall an app to see if the phone then goes into deep sleep

go to settings>accounts&backup>accounts> Google account>sync account>
Do you see anything with a circle formed by two arrows? those items can't snyc in the background for some reason. usually because the phone has put the app to sleep, optimized it, or restricted background data access. turns out my contacts arent syncing right now, glad i checked.

Are you debloat with adb and console?
Which apps disabled?
I think that Note 9 exynos have problem with consumming battery in sleep mode.
My N9 always "drain" 3-4 % in night after little debloat but A5 without debloat and with more apps consumming only 1-0% per night.
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

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.
