Hello, my G928F Europe version drain battery so fast, I checked battery usage, Android OS and Android system drain most of battery, always more than screen and any other apps, especially, android OS always stay awake, even the screen is off. Drain 30% battery in the night(8 hours sleeping time). However, if I set up flight mode, it was only 5%. I have reset the phone, clean the cache and also disabled some services, it does not work.
Any body has solutions? I am really appreciate it.

If you turned on airplane mode and the draining was less, then it must be that you're living in place with crappy cellphone reception so the phone keeps on trying to find a good stable signal for you to connect. If you have crappy LTE networks, switch to 3G/2G or 3G Only from settings. That should solve it.
Flash arter97 kernel it helps you out.

This is because your cpu never goes to deepsleep

Hi, I don't know what to do, I'm running 4.2.1 stock on my 32 3G N7. The tablet cannot go in deep sleep because of constant baseband_xmm_power kernel wakelocks. I tried factory reset, but the problem persists. For example with 5h the screen off, there are >4 hours partial kernel wakelocks.
Same here and I'm sick of it. Sometimes my Nexus manages to enter deep sleep but I still see a significant percentage of that kernel wakelock. It also happens that wifi won't shut off on sleep, and I'm talking about when it truly enters deep sleep, and it's correctly configured.
I have the same problem. Battery life is really poor due to this. My LP core is running at full tilt for at least half the time the screen is off, preventing deep sleep.
I found a suggestion that turning on flight mode and then rebooting might help, but I think the problem recurs pretty quickly if not immediately.
Saw a post that said it's due to the modem switching power levels when radio reception is poor. That would definitely make sense in my case — 3G reception fluctuates a lot at home and I am constantly losing connection. I have removed the SIM and will check it in the morning to see if there's any improvement. (Using BetterBatteryStats).
Hope this bug gets fixed in the next update. Almost thinking I should have got the vanilla wifi model
________________
EDIT: Removing SIM overnight doesn't help. Over the course of 8h screen off, baseband_xmm_power was active for 7h 46m!
I'm having the same problem, only when mobile reception is poor. Unfortunately, my mobile coverage at home is currently near-zero, which makes using my tablet as an alarm clock a dicey proposition unless I plug it in overnight.
I'm found my droid turbo shows major drain from cell standby, especially when with light uses. I will attach picture of my recent battery screen shoot. My phone is in battery saving mode for GPS, auto brightness & Bluetooth off. I wonder if others also experiencing the same issue.
I'm having this same issue. I've tried to optimize my settings but can't seem to figure out how to reduce this standby battery draw. Here's some screens.
Sent from my XT1254
I sure am seeing a lot more battery drain on standby. It was down by about 45% overnight when I did nothing on the phone.
This isn't normal, I'm getting upset

"Cell Standby" is a function of maintaining a connection with the nearest cell tower, including the data processing on the radio circuit needed for this. If this is your *largest* power drain, then that actually shows that the rest of the phone is running very efficiently. When the screen is off and nothing much is really going on, the ONLY thing that will be consuming power, is the cell radio.
If the cell standby stops consuming power when the phone is idle, then your phone will not ring when someone calls you.
30 hours of standby and 3 hrs SOT and you're unhappy. Thank god I don't make mobile phones, this type of stuff would drive me crazy. Do you not live where electricity is readily available?
Hi,
My S6 Edge+ has been using the battery a lot while not in use - it loses about 40% over night (so about 5% per hour when not in use). When I got the phone, I flashed a custom (rooted) ROM I found here on XDA (Audax was the name, IIRC), but I think the battery issue existed before that. Right now, I literally do not have any apps installed, the phone is as it comes out of the box. So far, I've tried the following:
Wiped cache and did a factory reset
Flashed stock ROM with Smart Switch
Flashed stock ROM and recovery with Odin
Turned off WiFi, data connection, location, bluetooth (bluetooth is always off, I don't use it), NFC, all Samsung S-Apps, everything I could disable, I did
However, the problem persists. I installed Wakelock Detector Free by using the ADB method described in the app, and left it over night (~8 hours). The result is terrible - the phone got a mere 0.2 seconds of deep sleep over night, meaning it is constantly awake, and the culprit is Android OS. From the looks of it, TimaService is the cause, but I'm not sure if I am reading it correctly, since it is on top, but it only says it kept the phone awake for about 15 minutes. Is there anything I can do? I am getting 8-12 hours of usage time, I have to recharge it twice a day just to get through a day of use. I tried searching online, but I can't find any solution that works.
Facebook app is the worse.. delete it or disable it
---------- Post added at 01:47 PM ---------- Previous post was at 01:41 PM ----------
theres alot about it on other phones. some say google+ some say knox. try disabling one at a time.
I don't have Facebook, Google+ or anything else running. Both Wakelock Detector and Samsung's Battery Stats report 'Android OS' as the cause of battery drain, by a far, far margin.
[edit] Also, I don't have Knox, neither.
For what it's worth, I flashed the Arter97 kernel and, after a few days, it looks like the issue is gone, I am now getting good battery life, both when using the phone and when it is idle.
Hello everyone, I am experiencing the worst battery life I could ever get from a phone, Any way to help it get better? I need to charge my phone 2-3 times daily!
Here are the screenshots of the usage.
Same here as well. I'm on the new Oreo that now has been pulled. Lots of errors, missing picture in picture, but biggest mistake is that all files are allowed to be installed without consent!. How to now go easy back to Nougat?

Go to device maintenance click on battery. Click on MID choose customize option at the top before you apply. I just leave the limit cpu speed on. I get over an hour sot every 18% YouTube alot and music. Only thing is apps start to lag when you switch really fast. But it probably won't if you don't close it. I have a habit of closing all apps before I turn my phone off. Whatever govener Samsung is using always max out the cup when you click something which drains the crap out of the battery. I use to charge my phone every half of the day until I did this. Closing and disabling apps didn't help at the beginning. This was the most effective way for me to see a big difference. Btw using auto brightness at 45%

Install a data monitoring apps, maybe you have some apps working in the background and draining the battery at the same time.

having data on chows battery, phone is excessively pinging towers, if you are on WiFi disable data in settings, make sure your location is set to battery saving (if using GPS yr battery will suffer, plus one only needs GPS for navigation), there are a bunch of bloatware apps and processes that run continually so install a package disabler or use a debloater to remove the 'junk'.

I am on data 24/7 I am only allowing 3G/2G to work, maybe that's the problem?
This time I tried something new, I entered *#0228# code when the mobile was at 15%, turned on Airplane mode and let the phone charge till 100%
I also turned location off and thing started getting better

Havng data on 24/7 will hurt, even just 2g/3g as phone is pinging towers for 3G, if you are i wifi area switch of Data, that'll be worth 20%
After Oreo update, I'm having the best battery saving of all time.
0.8%/h on stand-by (using dual Sim cards). 6-7h SOT. On Nougat, it was 3%/h on stand-by and only 4-5h SOT.
I did 4 things to achieve it (without root):
1. I followed this guide:
https://forum.xda-developers.com/galaxy-s8/help/guide-hunting-wakelocks-battery-drain-t3697324
Note: "Service Disabler" functionality was removed due to Google Play policies. Fortunately, the developers provided the previous apk with this functionality at their website: https://kunkunsoft.wordpress.com/news_2/
2. Switched to 3G when 4G signal was weak (2-3 bars).
3. Used Brevent app (must use adb commands every reboot, unfortunately): https://play.google.com/store/apps/details?id=me.piebridge.brevent
4. Used Tasker to: disable WiFi when Screen-off (except when Spotify is playing); disable Auto-Sync when Screen-off and enable it every 20 minutes; put Location Services to Battery Saving when Screen-Off (except when Waze or GMaps is running) and High Precision when Screen-On.
AutoTools (Tasker plugin) will let you modify some of those adjustments even without root (must enable it once via adb commands).
BBS and GSam are great tools to find out what's draining your juice. For me, it was mainly wlan_wakelocks (due to bad WiFi configuration), nlp_wakelocks (apps and Google apps draining when High-Precision is on), and Auto-Sync. Sometimes it's harder to identify the culprit because many apps wakelocks are hidden in Kernel wakelocks, so the first step above helped me significantly reduce Kernel wakelocks.
Cheers. ?

You have used your S8 continuously within 6-7hrs.. S8 does not have bigger battery plus the apps like facebook, other social media apps drain battery like hell... getting 3-4 hours of Screen on Time is quite OK not Bad...
try using other app for facebook.. like FRIENDLY.. it almost same as facebook and battery friendly also...

That's interesting, I use it all the time as well and for me it never goes above 2% or 3%. Only thing is that I don't do calls.

Hi,
After updated to latest firmware 16.2017.1912.060, my mobile battery is draining very quickly in standby mode. While using it's working fine. But in standby mode I am facing this issue. I closed Bluetooth, Location, Internet (WiFi and mobile data) and put my mobile in Battery saver mode while sleeping. Morning when I checked my battery level, it came to 36% from 85% in standby mode. My screen usage after full charge is 1h10min. So please tell me how to resolve this issue or how to downgrade to previous update.
Thanks.
version 318 , good battery backup
Thanks for the reply.
I got solution from the link
https://www.asus.com/zentalk/in/forum.php?mod=viewthread&tid=297817&extra=page=1&mobile=2
Just made a factory reset on your phone. I think After that your problem will be solved. Because sometimes many third party apps running on background and use the battery. That's why we can't traces how the battery dropped too fast even you enabled battery optimization or in safe mode.
