Update destroys battery life? - T-Mobile Samsung Galaxy S7 Edge Questions & Answer

Hi all...
So, I think I may have gotten the latest update last night, and I think it may have broken all sorts of things. My battery is draining faster than my wireless charger can actually charge it (which has never happened before), and I can't seem to install apps from Google Play. It's super awesome.
My friend with the same phone seems to be experiencing similar problems, and I was just wondering if anyone here was too?

Update: I just plugged my phone into Smart Switch, and it found an update . . . soooo, I don't think that getting an update last night was the problem. I'm running the update now and we'll see if that solves the issue.

I do experience battery drain. This phone battery life gets worse and worse each update. Screw this 3600mah

It's the latest Oculus update. Freeze it or uninstall until fixed. Oculus home is trying to install over and over again.

I'm thinking is the oculus update as well because my lookout continues to scan oculus rooms every 2 mins. It's just a weird coincidence that it happened about the same time as the update though. I'm having severe battery drain, texts and mms not being sent or received sometimes, and generally laggy overall.

Oh man, thank you! The battery drain is being reported as "Android System" which is no help at all. I'll give the Occulus thing a try

Mine is draining from the latest good lock update

Since updating this morning my phone runs hot and the battery drains 35% an hour. Charging is slow and phone has tons of lag. Worst device performance i've had since i ran ICS on my HTC G2
I'm wondering if using adoptable storage is causing it. I'm actually backing up and attempting a factory reset in a bit. My device is not rooted. Never even attempted root on my S7E.

Mine is smoother than ever. But im carefully looking at the battery and it seems to be draining faster. I have to look at oculus. But it doesnt seem i have that install

My phone has the same problem. Lookout is scanning Oculus Rooms two or three times a minute. So, is it an Oculus problem or a Lookout problem?

What baseband version you guys got?
I flashed my phone from sammy mobile (on the 28th i believe) dated 9/21 and security patch dated 9/1 and seems to be working much better than it was prior. Phone was getting hot and now it has not at all. on 2nd day right now. I still having used my wireless charge though.

I had the same issue. I was having extreme lag, overheating, battery drain(54% drain in less than two hours and it was in my pocket) and the screen kept refreshing every few seconds. All my apps were basically affected. The worst was snapchat and the keyboard. I saw the post on reddit about oculus being the problem. I uninstalled all the oculus and gear vr apps that could be unistalled and disabled the rest. My phone is working perfectly now.

It was the Oculus update. They (Oculus? ) pushed a fix out and now it's corrected. Confusing for users of Good Lock, because the Oculus problem happened the same night as the 9-29 Good Lock update, which was also very buggy. Uninstalling the 9-29 Good lock did not fix the problem though. All better now thanks to the Oculus Home update. I believe Good Lock was also fixed with the 9-30 update. I haven't gotten the OTA software update yet (PIA).

Woke up this morning and my battery was down 40%, rebooted which is recommended anyway everything mellowed out, charged my phone back to 100% have over 4 hours of screen time with 47% left. I disabled lookout because it's always scanning and running chewing up battery. I have no idea what Oculus is. Duh on me I guess

[Q] Android System is draining my battery a lot since I updated my phone to Kitkat

Before the update everything was fine. Now if I turn on the screen or listen to music the phone would awake (it would show that it was asleep in jellybean). When I turn off the screen and I am not listening to music then my phone falls asleep. Android system used to be awake under 20 mins over a 15-30 hr span now it can be well over an hour in 4-9 hr span. I did a factory reset yesterday already, uninstalled all of my apps and reinstalled them when I seen that the problem still exist. I googled the problem, but can't find a solution. Is anyone else getting a Android System battery drain like me.

Yes, I am having the same problem. I was told to do a factory reset but I cant even back up my phone with kies because it the MTP driver keeps failing to install and Kies says I have to use Kies 3 even though the Samsung Site says 3 is for the Galaxy Note..
Did you sideload your update or was it OTA?

that is odd. I was reading the forums on the sprint galaxy note 3 update, and people have posted pix of their battery stats. Their stats looks similar to mine. The people there was saying that maybe the problem would fix itself over a week. Im hopping it do, because I am really loving kitkat...minus this issue of course.

oh wow. You definitely have an app that is not liking kitkat. Your phone does not fall asleep when you turn your screen off. Im really trying to figure out why your phone is doing that. Im going to assume that "lookout" and "Malwarebytes Anti-Malware" are the problem. My opinion is that you don't need those as much as you think you do. they are most likely the cause of your drainage. My phone falls asleep as soon as i turn off the screen. Now i have 90% battery life with almost an hr of SOT left, and thats on 4g LTE the entire time.

I had alot of problems when on wifi, don't use it anymore and sticking with 4g. I'm at 30% left with just over 4 hours screen on. I'm guessing it's something either Google or Samsung have syncing more often on wifi, on wifi I'd be dead at 3 or 4 hours screen on time

Thats interesting. I haven't used my phone on wifi yet, because its a little inconsistent right now. If your phone is acting up while connected to wifi then it got to be something on samsung's end. You can end up with just over 5 and a half hrs of SOT if you stick to 4g and don't want any problems. I would keep testing how things go on both wifi and 4g over the next couple of days if i were you to see if the problems continues though. What problems are you getting while connected to wifi?

Another one of the major problems I am having is that sometimes my apps don't work. When i clicked on the camera it did not show up the app opens but the camera does not turn on. This leads to a major lag and when I try to press the home button it does not work. Then my phone's screen just shuts off and I cant turn it back on via the home button or the power button.
This also leads to the phone getting hot and losing the battery very quickly..
oh and btw the S5 does not seem to impressive to me..

i reset the phone and didn't install any apps and come to find out that its something that is already on the phone. I had no apps on my phone and android system and android os were in the top three that was taking up a lot of battery.
I recently had an issue with Android OS draining a lot of battery. I read somewhere that disabling stuff from Google sync that you don't use can help, so I disabled sync for all Google services except the ones I use, such as contacts, calendar, app data, people details, and play books. I rebooted and watched my battery for the next couple of days. And it worked. My battery life is a lot better, and Android OS is not using nearly as much battery as it did before. Perhaps this will help you guys?
***UPDATE on HOW TO FIX***
I HAD terrible batt drain with nae.. so bad that i left the device on the charger overnight qnd woke up to 35% batt... i got mad and reflashed stockish v6.. but.. batt drain was the same...
so.. here is what i did... i ended up flashing negalite r6 and the batt was so bad my phone would be dead within 1hr.. SO, FOR KICKS, i reflashed the MK2 modem and HOLY COW!, problem solved!!
im currently on negalite r6 ( a nae rom ) but using the mk2 modem and my batt drain problems are gone. in fact im getting great batt life. i didnt change the kernal or anything. i have flashed ktoonsez kernal over it, and it has not effected batt life at all...
in conclusion, if ur batt life sux, try reflashing mk2 modem.. it worked for me.. and yes 4g, mms, calls, and wifi work without any problem...
hope this helps

Does GasBuddy still cause a battery drain problem for nexus 6p users?

So I noticed that the newest version of GasBuddy says they fixed the battery drain problem that was affecting certain phone models. I decided to test this the last two nights. I Uninstalled GasBuddy and left my phone unplugged while I slept. I lost 2 percent from 100 percent. Then last night I tried with GasBuddy installed. I lost 20 percent and the keep awake time for android os was more than 8 hours. Is this still an issue for other people? I love GasBuddy and I hate to keep it off my phone.
Sent from my Nexus 6P using Tapatalk
same - the update didn't fix it.
it did cause mad wakes for me, uninstalled it last week, i will wait longer until i know its fixed for sure
going to mobile version of the site from chrome and adding to homescreen for the time being seems to be better option instead of installing the app. Also this seems to be fast.
I haven't seen any battery drain at all, I read somewhere that it had something to do with bluetooth, which I don't use
Well I sent then an email hopefully they can fix the 2nd time around
Sent from my Nexus 6P using Tapatalk
Yes, problem still here, had to uninstall GasBuddy. Strange that it needs bluetooth and then GB doesn't even show up in BBS as holding a wakelock.
Just Greenify it.

Does that fix it? Have you tried it? I'm afraid that once it triggers bluetooth to keep the phone awake it may not go away even if you Greenify it. It feels like something wrong in the bluetooth stack that GB may trigger. I can't explain why GB doesn't show up in BBS or the Android battery monitor.

No, apparently not. After reading this thread, I started GasBuddy for the first time on my new phone and put it right on the Greenify list. Constant wakelocks anyway, and battery took a steep downhill trend for the next few hours.

Yeah, this may point to a Bluetooth stack problem and not really a GasBuddy problem, though the app triggers it. I'm sure there are other apps out there that trigger the same.
Wow thank you people... I noticed in the last weeks that, as soon as I use the bluetooth and then stop using it (I disconnect my device), if I let the bluetooth activated, my phone was awake all the time. I couldn't find WHY !!
Then I saw a post from someone who said that the fix was to remove gasbuddy. I couldn't believe it, but I did the test and it's true !!
Gasbuddy is the culprit
It seems to be fixed now, in the latest release. I'm running it and have actually uninstalled Greenify. I never turn BT off. Battery life is excellent.

I just did it again :
I installed GasBuddy, I turn bluetooth ON, I connect my headphone.
I start TuneIn and start playing anything for a few seconds. Then I stop it and I disconnect my headphone and I let the bluetooth on
here is the wakelock again.
I only connect to my vehicles and laptop with BT, which I've done several times since loading GasBuddy's fixed release. No issues. Ended the day yesterday with 92%, including a couple of BT phone calls from my truck.
I'm also using NapTime, using the Aggressive mode.

Terrible Battery Life, battery says bluetooth is to blame

Recently ( Since the marshmallow update) I've been getting just absolutely horrendous battery life. I'm talking around 6 hours. Which is just unreal! I've had the phone for about a year and half and I find this ridiculous. Going through the settings/battery panel it says bluetooth has been taking up ~50% of the battery but that makes no sense since it did not do such before the update.
This is just so frustrating because it's such a great phone. Maybe I just need to replace the battery but who knows. Any insight would be absolutely amazing!
It seems to me that several apps can be the cause of this issue (bluesleep wake lock). I experience it since I updated my Note4 to DBT 6.0.1 PDA N910FXXS1DPG1, CSC N910FOXA1DPE1, Phone N910FXXU1DPB1. I disabled almost every app that has Bluetooth access, still bluetooth hinders the phone from deep sleep. Very annoying since I also wiped completely and reinstalled the image. Only solution so far is to disable BT. Will roll back to DPE6 or DPE1 soon, but am concerned because of missing security updates in that case (rooted).
See also this N6 thread.
So I reinstalled DPE6 and experience the issue right after booting and installing TWRP/SuperSU, with only Better Battery Stats installed. Could it be hardware related? I remember having this issue for the first time a week ago or so, without any new app being installed or other change made to the system.

[Solved] New High CPU Usage, Battery Drain, Overheating, etc.

Woke up this morning to my S7 Edge being extremely hot. I immediately took it off the charger because I thought the battery was maybe overheating, but it now appears to be a CPU usage issue. It will not go below 50% usage (often staying at 90-98%. The phone is continuously hot and battery drains ~1%/minute without usage. I have tried restarting the phone multiple times without change. Any suggestions would be welcome.
Update: the issue appears to stem from an Oculus automatic update. Uninstalling the Oculus app solves the issue. Read more here: https://goo.gl/Mt5FJy (thanks AVKillah)
High CPU and battery drain
I woke up to the same thing this morning. Phone running hot (processor-based problem, not the display or the charger). Have rebooted several times. It doesn't help. I can't find the offender app. Android processes are taking up most of the battery usage according to the battery monitor. This has never happened before.
Anyone have a fix?
Same here! Just late last night before bed.
The phone is running hot, lagging, keyboard constantly closes.
Trying to install anything hangs forever. Reboots and ram clears are not helping.
Haven't tried full cache wipe yet
Already tried full cache wipe through recovery. No change. Thinking about factory resetting but I have so many settings that would be wiped out...
Ultra power saving mode helped. Don't know if it's temp yet but at least while i was in it and for the moment since i just came out

Ultra power saving mode did help too. Booting in safe mode was also a solution for me, but you can't use any apps in safe mode so it's really pointless. It's also hard to narrow down the problem since I haven't downloaded an app in weeks and the only thing hogging resources is the android system.
I'm having a similar issue with performance and phone running hot. I am suspecting it is related to the PH1 update (noticed you have it as well). Device has been performing very poorly lately .
Factory reset has so far resolved the issue. May be related to PH1 update as I took that a couple days before this issue occurred. Will keep this thread updated if problems reappear.
So for the others affected is it all the same?
I havent taken any updates or changed my rom.
Nothing that changed that i can think.
Just that we all started experience this either this morning or before falling asleep?
I am having the same problem. It started this morning. I thought it was the copy of "Disconnect Pro Privacy and Performance" I got from the Galaxy App Store, but it persisted after uninstalling that. In the battery usage last when you select "Android System" it shows a list of the processes, and GearVR was on the top.
I tried to log in, but if forced an Oculus update which just hung on the install. I uninstaled all the VR stuff I had and froze the Gear VR Services app. That seems to be the culprit for me. It just kept trying to install an Oculus update that wouldn't go.
Phone is back to cool and normal battery drain so far. Will update if that changes.

Fun fact... I woke up this morning and because I hadn't disabled the "Gear VR SetupWizardStub" and "Gear VR Shell" as well they had auto-reinstalled Oculus and it, in turn reinstalled a bunch of VR apps. After re-uninstalling things again and freezing the last couple VR things my phone is continuing to run cool and with back to normal power drain levels.
Yeah apparently it is Oculus. Uninstalling mine.

Alas, that appears to be the issue. Unfortunately I factory reset my device before figuring this out. Probably needed a refresh anyways (probably not). Live and learn haha.

BUGS & BATTERY USAGE on JULY official rom

hi MI A1 owners.
for those brave enough to use the latest vanilla, official OTA rom, what change did you notice?
does the battery still suffer huge drain that appeared in 2018 roms?
it's a big "NOPE" for me to update, i'm still on official DEC rom because of this drain issue.
Battery life is good on 8.1 no issue for me getting 5-6 hours SOT on gaming.
Never had battery drain problems. Only "issue" is notification led not blinking.
Just noticed that led light is no longer blinking when notifications arrive. Light stays on only when screen is off. Also Bluetooth is constantly disconnecting.
Ambient display isn't working for me.
Led notifier is also not blinking anymore!
Led not blinking, proximity sensor doesn't work properly all the time, some scrolling lag. That's what I've got so far
dudes thanks for your answers.
i'm just more convinced to not doing the update.
maybe the drain i had was magisk-related. (?)
Nothing for me, even got ten hours of screen after some cycles. Led doesn't bother me and it's the only thing i noticed.
Yes, the LED is always on, which is annoying, but the bigger issue is there is no change in the battery drain. I charged to 100%, set the phone down and did not move it or use it overnight. 8 hours later almost 14% of battery was drained. I have tried everything I can think of to try, including turning off high accuracy location, not allowing any location things like safe area, etc. and still I get this drain even when the phone is not in use. Android kernel and system consumed 85% of that usage, and System UI, Play Store and Phone Services accounted for 7%! SO basically, basic Android paired with the A1 hardware seems to be the issue and I don't know that there is any fix for that.
At one point, I thought an upgrade to the A2 was going to be a no brainer, but with the issues with updates being broken and this battery drain issue that nobody seems to be able to pinpoint and resolve, I am thinking I may not buy ANY other Xiaomi. It may be time to try something else because the only way I can get two days of battery is to turn on airplane mode when the phone is not in use!

Dunno what to say man. Mine is below.
2-3% at most over night.
And now it would appear that there is an issue with airplane mode.
I put the phone into Airplane mode at 2300 last night with 90% battery and did not pay attention to it. This morning I turned to phone on to find there was only 69% battery left, and WiFi was working. (see screen shot) WTF???? I have started using airplane mode to keep the battery drain to a minimum when the phone is not in use, and now it would appear that this doesn't work either.
I am REALLY getting frustrated with Android and Xiaomi as it seems that every time they do an update, something else goes bump! I have gone from totally happy with the AI when I first got it to being ready to write off Xiaomi as a company I would consider for purchase.

"com.google.android.gms_12.8.74_(090408-204998136)-12874034_minAPI26(arm64-v8a,armeabi-v7a)(480dpi)_apkmirror.com.apk"
Uninstall your current one. Install this .
Power off your phone for a few seconds and reboot.

Thanks for the thoughts, but unless I totally misunderstand what airplane mode is, WiFi should not be active when airplane mode is invoked. You can see by the screen cap that airplane mode is on AND WiFi is active. This seems to be a one off as it has not happened again for the last two days. I turn airplane mode on to stop the overnight battery drain while the phone is doing nothing. I have location set to GPS Only. IIRC play services was just updated 3 days or so ago, so it should have the latest version. I will check it and see though. Again, thanks for the thoughts.

At one point, I thought an upgrade to the A2 was going to be a no brainer, but with the issues with updates being broken and this battery drain issue that nobody seems to be able to pinpoint and resolve, I am thinking I may not buy ANY other Xiaomi. It may be time to try something else because the only way I can get two days of battery is to turn on airplane mode when the phone is not in use!

I can't logically understand why you would think it is the hardware causing the issue. If it was hardware, what you are seeing would be happening to every owner of the phone and clearly that is not happening. By saying it is the hardware when you have other software loaded is akin to saying your car's air conditioning doesn't work properly when you have all the windows wound down.
There is something loaded on your phone that is causing the systemUI to be working when you think nothing should be happening. The first thing I see on the screenshot on your phone is that in the top left of the screen you have two non standard icons. That tells me that you have a skin or non standard software constantly running.
The way to solve any issue like this is to go back to basics. I would get the fresh rom and do a Miflash whilst keeping your data. Make sure you do a backup first.
If that does not work, back up your data and do a clean install and check the phone's battery life. Do not load any non google software / app at this stage.
Then each day add one app and test for 24 hours. You will find this issue and the offending app or apps and I would be willing to bet you a few Singhas it will be an app you downloaded not the hardware causing this.

Actually, I think it is a combination of hardware/software, but that is just a WAG. Others have noted the exact same issue without running the same software. My bet would be on the RCS services stuff.

Those icons are my Email client and GSAM Battery Monitor (presently 0.1% and 0.8%) and are the only two constantly running programs other than the stock apps and Sophos (0.3%). Neither use much battery compared to the Android stuff. Presently Kernel is 41.6%, RCS/Phone is 30.3%. SystemUI is 3.3%, Play Services is 2.0% and Phone Services is 1.8%

Good advice. I will do this when I have a few days to play with it. In the interim, it's airplane mode every night. Thanks for the reply. If it turns out to be one of these apps, let me know where to send the Singhas.
Good luck with it. I hope you find the solution. It can be frustrating, but getting to the bottom of it will be worthwhile. I haven't used Sophos for a long time and even then it was for PC. I am not up with how Sophos AV is integrating into Android but that would be my first guess.
I have only had one issue with this phone after updating and it was that the OS was constantly asking for a password on unlock after using fingerprint not just on startup. A clean install solved it and I have been trouble free since with every update. With over 50 PCs in my office, I could only wish that I had so few issues with Windows updates as I do with Android.
For me, night light auto schedule not working properly.
I can't tether via wifi/bluetoth/usb
Made another post with the problem.

Just for grins and giggles, I uninstalled my email client, GSAM, and Sophos, the only programs that run constantly other than system and Line. I then turned my phone off and back on, forced stopped Line, charged it to 100% and set it down with the screen off. It did not move of get used for 8 hours, yet it still used 12% of the battery. (see screenshots) This is better than the 20% with those apps installed, but still not close to what I would consider normal. When I first got the phone, it easily lasted 2-3 days between charges, with 6-7 hours SoT. Overnight would use MAYBE 2% of the battery. Now if I want it to last 2 days I need to turn on airplane mode overnight and then I can make it through a day.
So I guess the next step is to do as you recommended and load up the fresh rom when I have time to mess with it. At least I am now pretty sure that those apps aren't the culprits causing the biggest part of the battery drain. I hate to do it, but I am seriously thinking of a factory reset and seeing if that clears the issue. Would that put me back to Nougat?

How do you disable this apk? I seriously think this is the major culprit in the battery drain.

So those apps were causing 40% of of the 20% of the battery drain. That is a good start. I am confident there are software issues with your phone. I see you have some GPS app on your home screen, if that was running askew, it might be constantly pinging. That is just a guess.
In things like this, work methodically through it. But of cause a hard reset would be the best way to go. I see no reason why you wouldn't stay on your current version after a hard reset.
If you want to go make to version 7 you would need to use the MiFlash program and a downloaded standard fastboot rom. You may need to do something else to the phone to go back to 7, but I would not think so.
