My battery life is horrible on 7.0? - Samsung Galaxy A3, A5, A7 (2017) Questions & Answe

I've reinstalled, reset, cleared cache nothing works. on 6.0.1 I would come home at the end of the day with 50/60% left. On Nougat I'm home and on the charger at 20% if I'm lucky.
I tried to downgrade to 6.0.1 but it wont let me. Any ideas? I'm lucky to get 2hrs screen on time, before I could get at least 5-6hrs

Try to disable unusefull apps, block their auto startup. As I can see in your shared pic, your gservice use a lot juice, so turn off auto ok google detection and other things what you are not use at all. I belive its possible to downgrade if this is your choice, but It requires the stock system file and Odin. And least Im happy with my screen on time, I can easily get 5 hours or more every day!

Yeah, its true. It slipped my mind. Probably this particular portion of the software was developed at the last moment, and they didn't have enough time to test it thoroughly
I have narrowed my wifi drop outs to the beyond pod app.
My camera won't focus after updating. I had the problem prior, but did the alcohol microfiber run to get the coating off and it was working great. After I updated the camera now seems like it won't focus, only objects within 5 inches are in focus. I did a factory reset and made sure that the camera wasn't set to macro mode. Nothing is working to fix this problem. I think my camera might just be broken now.

Now after a few days i think that the battery cannot hold on so long as with 4.4.2. Previously i could run it two days with moderate use, now the battery level drops to 20% after 24 hours.
At the update the battery was not fully charged. Is this behavior normal after the update, did i make a mistake, or does anybody else have the same problem?
I'm on 19% after 13 hours. WTF is going on? I cannot see any suspicious app causing this. Can i revert to 4.4.2? LOL...

I have (or had) the same problem as you with the new update. Try clearing the cache partition (that's what I've been told). I'm still keeping my eye on the battery to see if it's fixed. The problem for me was that Android Kernel and Android System was using too much battery.
Here are some screenshots:

These battery results are pretty bad compared to what I was getting prior to 4.4.3 (i got 2d5h once with 4h on screen and 7 hours awake).
Hi! I think i was able to fix it, the issue appeared on other devices which received 4.4.3. I cleared the cache for Google Play Store and for GP Services. Now i'm at 50% after 20 hours.

just tried that and hoping it works. I've tried turning off fast boot but having the same issues others are reporting also.
here is a post from another user:
Hi, everyone, this is my first time here, so bear with me. On Wednesday, August 28, I downloaded the new Kit Kat 4.4.3 update from AT&T onto my One M8. Right after and for a few hours after, everything was in great condition as always. I've had my M8 since launch and haven't had a problem since and hold it very dear to me. Then, after about four hours, I noticed the phone was getting hot, really hot. I had power saver on as always and I saw that the CPU was taxed at 97%, just having Instagram running and YouTube actively showing a video. So I restarted the phone, clearing the cache and making sure that nothing was working too hard. That's when the problems really started coming up. It was getting hot but I ignored it and went to the Play Store to update my banking app and download Reddit News. After seven minutes of a normally one minute (if that) update, I stopped the download, cleared the cache and tried again. Nothing. So Google Play won't download, update, or install apps, Google, or third-party. That's not all. Hangouts will not send messages. Even in full LTE connectivity and 5 GHz Wifi AC, message could not send both to Android users (one used messages, the other Hangouts) and to an iPhone. It was like deja vu with my old iPhone 4S. BUT THAT'S NOT ALL. YouTube was giving me hell, too. When I would type into the search bar to search for a video, the search bar would clear. For example, if I'm looking up and type into the search bar on YouTube "Linus Tech Tips," then it'll work. But if after that I backspace or "x" out "Linus Tech Tips," and type something else, say, "Build a Gaming PC," If I use Swype (Swiftkey, Google Keyboard, or HTC Sense), the first word shows up, but as I'm typing, the subsequent words are erased and "Linus Tech Tips" shows up in the search bar (check him out if you don't already). This is EXTREMELY frustrating and now I can't watch The Joy of Painting. Damn. Finally, the CPU and heat I mentioned before is crazy. The CPU is always between 79% and 99% at all times. the RAM is usually at about 75% as normal, but the CPU is running nuclear hot. It's going to 105-115 degrees Fahrenheit. This worries me, all of this, because I wonder if this is the fault of the new 4.4.3 update for the AT&T M8 model or maybe underlying causes. I've had Malwarebytes scan my phone and find nothing. That caches are cleared and nothing seems to work. If anyone can help I would be extremely grateful because my only option in my mind is to do a hard factory reset of the device. Thanks to anoye who can help, and if not, then, oh well. Thanks, and sorry I made an essay out of this, this is really a big problem for me.
another user just posted:
Well, I think that the factory reset fixed it. It's been over an hour now, and the phone isn't overheating anymore. Battery life has only dropped 2% in that hour instead of the 2% every five minutes after the update.
After the 4.4.3 update the camera's manual mode doesnt change the exposure the same way as it did in 4.4.2 so i cant see the pics in the viewfinder at night before i actually take the pic and look at it, and that really sucks.

[Q] Help required. Nexus acting weird (Battery+Ads+Apps)

Hi,
Need help here. I have a 4-5 month old nexus 7 2013 wifi only. It was all fine a few weeks ago, till i noticed a sharp decrease in battery life. I am running 5.0.2, stock unrooted. Around 3-4 hours of active use.
So I reset it from the settings menu. Agreed, there were not so many apps installed again, the battery life increased to 5 hours of active use. I noticed the sharp decrease because my skype time has decreased from 6 hours to 2-3 hours.
No major change after the reset. Except, my firefox addons for adblocking dont work. Also, just a very specific example, movshare . net also is blocked on my nexus, but works on my computer on the same network. This is annoying the living sh*t out of me, I just cannot stand all the pop ups and ads. I dont need fancy shmancy rooted adblockers, just need my nexus to work like before.
In general, I have 9GAG and skype crashes often, everything else works fine though.
Need to know hardware or software, whether to root or not to wipe battery stats and clear cache.
I owned a GSII a long time back. I modded it till it broke. Thats why im still running stock. If we can do everything vanilla, that'll be great.
GSAM shows 1d 2hr standby and 6h of active. Sometimes delta/h goes upto 21%.
HELP.
EDIT* Google now mic doesnt work all the time, only when I'm on the Now screen.
I'd wipe everything then flash the stock image in fastboot. Remove all variables and see what happens.
So lollipop or jb?
Castum rom + castum kernel + greenify + wakelock detector. and see that the battery sits down, the program may remain constantly running

Battery drain-wifi is awake all the day!

Hi,
I had my htc10 with Android 6 and used to get around 4-5 hours of SOT. Everything was perfect and used to get around 2 days battery!!
Than I get android 7 and everything got worse!! Now I get around 3 hours of SOT and if I have luck I can get 1 day (I am not a heavy user).
I did reset but it didn't help!
I am not rooted and I barely use wifi/gps/bluetooth through the day..
Today I recognized this:
At the history I saw that my Wi-Fi is awake all the day but the problem is that my Wi-Fi was OFF during the day!
I checked the Wi-Fi scanning at the location and it's off too so I don't know what is the problem!!
Please help! I can't understand why my Wi-Fi is awake all the time!
any suggestions?!
I didn't see this Wi-Fi ON all the time after Android 7.0 update, but observed last week because of battery heavy drain over night. That day for some reason Wi-Fi never went to sleep mode and found that playstore got updated to new version (with play icon). However, I did reboot my phone and didn't see that behavior afterwards.
Some options to try
1) Try toggling ON & OFF the Wi-Fi scanning option.
2) See if anything is enabled in Google Now launcher or Google Search bar on main screen.
If I come across anything else, I will post it here.

Thanks a lot
I already did those.. Today I checked it again and it seems OK (Wi-Fi went to the sleep mode over the night).. I will check again and I hope it will continue and not to see it again
But the series problem it's that after the update to 7.0, the SOT is far from what it was. I did everything (switch off every option that I don't really need like sync, GPS, Wi-Fi, cash clearing and...).
The Android OS killing me: around 20% every time..
Before the update I really get amazing SOT, but now it sucks

I get the update 2-3 mounts ago..
if you have viber check its settings, it has an option to keep wifi on
Check your battery usage stats, and look for apps that have excessive awake times, CPU times or Radio times for the phone, uninstall those apps, see if the battery improves, I never turn off my WiFi and don't have this issue. Anything using the cell radio is most likely the issue. Also if you have weak cell service, turning on airplane mode will help so it isn't constantly searching for a network.
I've the same problem as OP. Huge drain on battery since Nougat update
A restore to defaults after the update does the trick.

Anyone else getting severe battery drain from "Android OS" on 4.7.6 ?

My 5T is constantly losing battery due to "Android OS". I think it started when I updated to OOS 4.7.6 because it seems to have started within the last week or so, but I'm not sure.
I am currently sitting at 52% with 13 minutes of screen on time. 13 minutes.
https://imgur.com/a/Xfj7y
I know it looks like it's because of poor mobile connection, but that's how it's always been with T-Mobile in my area. Like I said before it hasn't always done this, so it isn't that.
I am rooted with TWRP and Magisk. Nothing too fancy just a couple of Xposed modules that I installed the same day I got the phone. So I know it's not any of those either.
I have already tried using Greenify to kill everything in the background, resetting app preferences, and wiping the dalvik and cache with TWRP. None of these has had any affect.
I really don't want to wipe and redo my entire setup, but it's looking like I might have to. Or even downgrade from 4.7.6 to a previous version.
I would appreciate any help and/or suggestions.
None here, been running 4.7.6 for a while. Mine is rooted, my wifes phone is stock, also running fine. Both average 7.5-8 of SOT.
No issues here.
Wow. Since updating to 4.7.6 I have been waking up in the morning to "xyz app" is draining your battery. Usually it is drive which I never use and other times its play services but its nothing like what you are experiencing. My setup has been exactly the same for over two weeks with no added or removed apps, the only difference is the update from 4.7.5 to 4.7.6. I had it dialed in where I would lose 2% overnight consistently but now I have apps draining my battery overnight and the loss is considerably more than that. Hope you get it sorted out :good:

Have you tried better battery stats app to check what's draining your battery? I use that app and it's pretty good.
My phone setup is pretty much like yours, just root with magisk and xposed , no issues here. I'm on stock recovery but TWRP shouldn't matter too guess

Do 1thing i also updated using VPN and m on 4.7.6 version but the battery life is great. I am not rooted just on oxygen Os 4.7.6 without greenify or any such apps. The battery is amazing always 7 to 8hrs and more slot easily. I just cleared cache from recovery and storage after updating and its also recommended on Oneplus site to clear cache after updating. It worked for me when previously i had battery issues . Try it should solve your problems.
Updated to 4.7.6 (full zip via stop recovery) when I got the phone (a week ago) and did a factory reset. Battery is very good for me.

I had this issue on my pixel and nobody seemed to be able to help or offer an explanation, your case sounds extreme like mine was, you could literally see the battery percentage dropping 2-3% per minute and the phone was running super hot.
No idea of the cause but I fixed it by a full wipe of everything, internal storage included, reinstalled everything from scratch no backup app or cloud or anything literally everything clean install.
Hope you get it sorted.
Edit -to clarify, when I tried a clean install of the ROM wiping data cache and system I still had the same issue when i had restored my setup, even in different ROMs, it was baffling. For me it seemed to be wiping the internal storage that cured it, I just backed up pics and anything else I didn't want to lose to my pc just wiped the lot, redone my whole setup from scratch and problem solved.
Just an update in case anyone ends up having the same issue. I fixed it by disabling WiFi. I have no idea why WiFi is causing the severe drain it does, but now I can easily go three days on a single charge and get 6+ hours of screen on time. Even though my phone reports a poor 4G connection almost all the time.
I hope this issue gets magically fixed in Oreo in the same way it magically started in 4.7.6.

That's weird, my phone is connected to wifi a good part of the day and I don't have battery drain. Wifi was on for 22 hours and I have 55% left. The phone is close to 2 days without a charge. I usually get 2 days out of with with normal use and 3 with lighter use.
Have you tested with an app like "Wifi analyser" how is your reception ? I guess it would eat more power with poor reception.
I've had my phone for 3 days, just started, I did the update and a factory reset directly.
I did a test by cutting the mobile data at night and over 8 hours I lose 1% on the battery.
So for me it's very good! :good:
4.7.6 here, not rooted, no such problem
I have this problem too. AndroidOS seems to keep downloading something in the background. I was able to make the problem go away by setting a static IP address in the WiFi settings.
I have used my Oneplus 5T for 8 month,recently the battery is total terrible ,for not use ,and just open one app,it drops battery from 70% to 17% in 3 hour !!And i charged it in 43% ,again drops to 10% in one hour ,then in mins closed without any battery.What a big joke ,i contact the customer of Oneplus ,respond very badly and does nonsense .Mine is 8GB 128GB android 7.1 ,a total rubbish now.Anyone in the same occasion?

Then please do not whine about having a bad battery life. Or when you do not want to update (although your reasoning is not logical as I am on 8.1 latest offcial which is working flawlessly) you could try doing factory reset.
I had OP's issue.
Clear Google cache
Clear Google Play cache
Reboot into recovery, clear cache.
I'm not sure what is required but I do all 3 and it fixes the Android OS drain. Fewer steps may do it? Never tried narrowing it down. My wifi is always off. Location (high) always on. (history/tracking off) App auto-update off.
Based on my circumstances I have a feeling it has something to do with google play app update notifications not coming thru due to bad signal but that's a guess.

One UI battery

Ever since I updated to Android PIE (One UI). I've noticed a major decrease in the battery. I was able to get a full day of usage with oreo, now I only get a little over half a day of usage. Not to mention the battery usage of screen off time is about 10-15% worse than what it was on Oreo...
I doubt I'm the only one with this problem, so has anyone found a fix to this? Or should I just revert back to oreo?
Model: Samsung SM-G960F
Make sure you factory reset after updating to Pie
I factory reset the phone after installing Pie and battery improved greatly. battery while using the phone is pretty much the same, but phone in standby time drains waaaay less battery than on Oreo.
You should factory reset your phone after every major update like this one

Is your google backup still working?
My SoT and standby battery improved graitly after deleting google accounts, samsung, and emails.
Only got twitter, fb, fb messenger as social media.
I know this is not a fix, but I did this, to check battery without google accounts activated.
I start to beleive my drain comes, from the phone trying to back up and get stuck, plus a play store that kept crashing.
It even showed at device maintenance, but then again, that one isn't working properly neither for a lot of users.

I've factory reset my phone. However I'm never gonna use samsung cloud to backup again, either backup wont work or restore won't work.
In terms of battery, it's gotten a little better, however I still feel like it was better back on Oreo.
Not factory resetting
I've owned my Galaxy S9 for a little over a month now, and I've done lots with it. I've installed a lot of apps and would hate to factory reset it and have to go through the process of setting it up again.
The battery has gotten worse on Pie but I want to fix the battery issue without factory resetting it. I know I can enable Power Mode but then I can't use Gear VR. Any ideas?

Clear cache from recovery
Install something like BetterBatteryStats and find out what is draining the battery (Needs some ADB commands to give it permissions but does not require root)
Disable AOD
Turn off background usage for apps you do not need to run in the background from that specific apps info screen
Dev Options > Background Check can also stop apps from running in the background
Turn off notifications for apps you do not need them from (I always assume if they have notification permission, they have to run in the background in order to provide notifications in the first place)
But the ultimate battery fixer after upgrading to a new Android version is and always will be a factory reset, you just cannot fix battery drain properly any other way, the previous OS leaves behind rubbish files which drains the battery, always been the case
I gave in and decided to back up my data using Smart Switch and factory reset. It was a pain setting everything up again and some apps just weren't reinstalled for some reason. I can confirm that the battery isn't as bad as it was previously, but it still drops by 1% every few minutes like on Oreo. I've turned on power saving mode and disabled AOD, but the battery still remains disappointing. Hopefully this will be fixed in a future update.
