I recently bought a used T-mobile Samsung Galaxy S5. It came running lollipop. The battery has been awful. I lose around 50% a day without using it at all. I frequently pull my phone out of my pocket during the day, and it will be hot and the screen will be on. When it is in airplane mode the battery life is normal, and there are no problems. I have tried resetting it, clearing the cache, greenify, and multiple battery saving apps. Nothing helps. Any suggestions?
Install a battery monitoring app, see what's causing it
Most likely due to certain apps you have installed that are draining your battery (maybe try rebooting into safe mode and see if the issues persist) Then use BetterBatteryStats or something similar and see which apps are causing it

Hi Guys,
I upgraded my Exynos Note 3 to Kitkat about 1 month ago, and everything was fine till about 3 days ago when I started experiencing some really bad battery drain. For the last three nights, my phone does not go into deep sleep mode at all. I first noticed this because I usually switch off data and wifi at night. Normally, I'd loose 3% battery overnight, which is good. About two nights ago, I woke up in the morning and I had lost 40% battery (90% down to 50%) overnight! When I checked out the battery stats, "gpsd" had used 80% of the battery.
Since we no longer have batterystats access in Kitkat, I installed the desktop version of WakeLock Detector, enabled USB debugging mode and connected my phone. Phone had basically been awake 97% of the time. Under kernel wakelocks, "l2_hsic" was shown as being the culprit. Now I have searched through various forums online (including xda) to try and find a solution to this. Suggestions vary from home screen replacements (nova launcher) to mobile tracking software (cerberus/findmymobile etc) to generally anything that uses location services. Some even suggest clearing application caches, disabling location services etc. I have tried every suggestion with no change. I uninstalled all mobile tracking apps, turned off location reporting, location history, and eventually location services. I've removed all battery stats apps. I uninstalled all my apps and re-installed them one by one, all with no change. Finally, I backed up my phone and did a factory reset. That seemed to work at first, but after about 3 minutes, "gpsd" was back again, and my phone would not go into deep sleep.
I've done 3 factory resets, and with no google account or samsung account configured, I still get "gpsd" rearing it's ugly head, preventing the phone from going to deep sleep and draining my battery. I'm at wits end.
Anyone know how to fix this? Would appreciate any help!
Anyone!?
OK, so I decided to take out my SIM card, just to see it'd make a difference, and what do you know! "gpsd" no longer takes up CPU time! So this is somehow related to my SIM card? Funny though, coz I'd even tried putting the phone in Airplane mode, but "gpsd" was still taking up CPU time. Does that give anyone an idea as to how this can be fixed?

I'm having exact same issue with my exynos Galaxy S5, shame Samsung.
For the record, my issue fixed itself. Didn't do anything at all. It just went away and never recurred. I'm on the Russian lollipop ROM now, loving it!
Almost a year after the issue fixed "itself"... I have the same problem with my SM-N900 running offical lollipop, Im afraid I cannot wait a year to let the issue fixes itself... and cannot find a solution either.
Anyone that have managed to solve this?
THANKS IN ADVANCE!!
Huge battery drain when tablet is "sleeping" - probably because "bluesleep"
Hello,
I have problem on my N7 with large battery drain.
I had this issue witch Stock ROM, now I tried to root stock ROM (4.4.4) and install Greenify, but battery still dies after 2 days of no usage.
I tried to charge it fully, reboot it, cleared cache and dalvik cache, and put it to "sleep". After one night, 40% of battery was gone.
It seems that my N7 is not going to "deep sleep" for some reason.
So I tried to install numerous of apps to find what app is responsible for this. None was successfull, until I tried BBS.
In attachment, you can find BBS dumpfile. But it seems, there is some "bluesleep" kernel wakelock, which is responsible for all my troubles. Unfortunatelly, I dont know what this process is. Or am I reading dumpfile wrong and some other app/process is responsible for this huge battery drain?
I also attached screenshot from standard android battery statictics, which shows, that "Android OS" is preventing tablet from sleep.
Is there some way to fix this issue? Tablet worked normally for 1.5 year, but in last months is unusable, because it has dead battery everytime I want to use it.
Thanks for advices.
I would imagine bluesleep wakelock is related to bluetooth. Do you have BT on and/or connected to anything using BT?
If so try turning it off and see if it persists.
Yes, I use Bluetooth for my Jawbone UP24 sync. But I have this band only for a week. Extreme battery drain already was there before I have got UP24. In these times I had bluetooth turned off all time. So I dont think this is main reason.
I turned off BT. Lets see what happens in the morning.
UPDATE: You were right. It is bluetooth. When I turn it off, tablet is most time in deep sleep.
So probably rooting and installing greenify worked, but in meantime, I started using UP24 and Bluetooth on tablet.
I will try if situation is better with some AOSP based ROM. I did not wanted to flash another rom (than Stock), but I guess, there is no other way. Even clean Android on Nexus device is not usable with comfort...
Is there anybody else with this problem.It started monday i turned my phone on but it didn't start.The battery was 0% while i shutted it down with 78% of juice left.I charged the battery but it drains down real fast!Even with the screen off at night and no wifi or edge/3g/4g i still lose about 10% every hour!
I've used the note for two weeks without any problem.Rooted with Xposed Greenify and most of the bloatware disabled.Same setup as my Notepro 12.2 and galaxy mega(no problems with those devices).Battery life was pretty good about 5 a 6 hours of screen on time.
Tried better battery stats but no particular wakelocks or anything??I've ordered a new battery and that will arrive tomorrow.I can do a test then if it is the battery or the phone which is causing this problem.
It's a note 4 910c.
I have similar problem with my 910C...Everything was ok for first two weeks and problems started when I enabled LTE at my mobile operator. No matter what I do, I have huge battery drain like you said. I've also tried with disabling 4G/wifi/data/sync/airplane mode/removing apps... I even tried factory resetting 2-3 times and flashing stock rom via odin...Nothing helps...
I'm looking around on various note4 forums but I'm getting out of ideas...
I had an initial battery drain issue which ive managed to resolve. Took a few factory resets but for me it looked like the galaxy apps ap. Once you open it a single time it updates a few things and thats when i started to see wakelocks. Ive reset and avoided the galaxy apps completely and now wakelocks have gone. Might be a placebo but seems to work for me.
I have 2g,3g and lte enabled.
Oke i enabled 4g from the first time i used it so i don't think that is the problem.I was thinking about a factory reset but i'll wait with that untill i tested the new battery.
Will give a update tomorrow!
I had the same problem after one week of normal use. It was a hardware issue and the service center changed the phone board under warranty.
Well tried a brand new battery but still the same!Lose at least 10% every hour and i am not even touching the phone!!Sending it back for another one.
It's happened to me once but touch wood only once where I lost 70% overnight in airplane mode
Could be the media scanner? I was having media server and scanner drains until I installed a custom rom and disabled it.
Hey guys,
I've been having an S6 Edge+ for a couple of days already but there seems to be an issue with the ROM. I'm getting a lot of battery drain from the "Android OS" and I'm losing up to 5% - 7% per hour in standby.... I have even re-flashed the entire ROM and factory reset two times... still the same.
I've disabled Google's Location History and Google Now but this did not help...
My previous Galaxy S6 was also running the latest ROM but there were no such problems...
Has anybody else experienced such an issue and do you have any ideas?

Check if any sync is stuck in loop, sometimes this kills battery very easily. If all else fails check with some app like GSam.

Unfortunately GSam does not produce too detailed information without Root access and it only says Android System and lists all the services that are under it...
The interesting part is that after several re-flashes with the same firmware, the wakelock disappeared...
Now I get 76% to 80% deep sleep...
Go figure... Probably some stuck sync as you mentioned...

Android OS Wakelock killing the battery! ...... solved
OK, im not too savvy with settings and systems, just sharing what i have been through. I too had a major battery drain problem on my S6 Edge+ , giving me abt 8-10hrs of use after a full charge. Even during the nights with everything off and power saving enabled i would lose abt 50-60% battery over 8 hours. ..... caused by Android OS ....... it would keep the screen awake for hours even with the screen off .... ( dont know how that worked) ..... tried a factory reset but didnt help. Then rooted the phone and downloaded wakelock detector and installed it as a system app. Installed greenify and doze ..... last night lost 4% over 11hours with wifi and 4g off and power saving enabled which is a drastic improvement. Facing one little problem that images do not get downloaded (automatically or manually) in whatsapp with wifi in use. Will use the cell for a few days and post again abt how the battery is holding up and if there is any other performance issues.
If you want to save battery, try this app:
https://play.google.com/store/apps/details?id=com.kunkunsoft.packagedisabler
It show all RAM usage of each app, you can disable any app in Bloatware (samsung default app) list to save power
This app run WITHOUT ROOT

1. Install one of the available battery monitoring apps. I recommend BetterBatteryStats:
https://forum.xda-developers.com/showthread.php?p=15869868#post15869868
2. Read carefully the instructions/help
3. When you get some knowledge about battery overview and wakelocks -> analyze the results from the app by your own and try to find a cause for your problem or
4. Make proper dump file from the app and post it on the BBS thread asking for help.
