After 4.4.3 (Problems/Features)

Let us know what your have found after the update. Good and bad.
Since the update my WiFi has dropped out on my home network twice. Have to restart or turn airplane mode on/off.
Also I don't think the battery has improved any....

After the update, at the settings / power the scrolling is laggy. This module was updated, something is just not right at my device. I did a factory reset, no avail. It's lagging only over here, pretty annoying...

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.

Crazy Android System ?!

About 3 days ago the battery drain on my Nexus 5X went crazy. I found out that the "app" Android System do not let the phone sleep and keeps it awake all the time. That is why the phone can not even get into doze mode and drains about 8% per hour when the screen is off. I tried restarting the device and also force stopping the Android System. Both without any succes. Do anybody knows what to do with it? Or should I just wait if it will go back to normal? I do have screenshots, but the XDA will not let me post outside links...

Interested about that.

Well just delete the two underscores and the "dot" thing

I am having the same problem. It occurs randomly, most often when I have just charged the phone and removed the cable. If i am correct, a wakelock under the name *backup* is holding the phone awake, it might be the same in ur case. I've done a research on this, turned out this is unfixable unless you have some sort of wakeblocker, which my current rom lacks of. I tried using xposed with its modules, but it gave me a ton of bootloops and i gave up on it. The only temporary fix for me is to reboot the phone. Until it happens again. No clean flash nor anything i have tried seemed to have helped. I even tried disabling all services and receivers from Android System, no luck again. That is one hefty problem

I have exactly same problem with wakelock. It happens only after charging. Everything is OK after restart.

It has happened to me sometimes on my old HTC One X and I think it happened also once on this 5X, but it was just for about a day or so. It disappeared itself with time, I didn't do anything with it then. Now it's been 6 days, I have to charge the phone twice as frequently and neither the reboot nor the force stopping everything works. I really don't know what to do in this case. Also this phone isn't rooted yet, so I can't just flash the system again as on my old HTC... I'm still hoping it will disappear by itself asap
But do you anybody have any other ideas what can I try to do to stop that crazy system app?

same problem here...
had the phone about 350 hours with no restart and i thought i would give it a reboot..
same think happened...android system was going from 2% to 20% in a matter of hours..
installed an app called GSam Battery monitor..showed me the phone was not going in deep sleep (Doze mode) at all...
here is an attachment if anyone can understand better than me..

I posted a similar thing in the battery life thread. Very odd really as I've had the phone a few months now but it also only started with me a few weeks ago. Really can't think of a trigger for it... I doubt the April update would have been significant enough to create an issue, but who knows.

Exactly. After about 4 months of working excellently and about 400 hours without restarting, after charging it's immediately goes into this "mode" when the Android System won't let the phone sleep. Even restart didn't help me, but now after 3 restarts it goes to normal. One bad thing... after every single one charging, every time I put the phone on the charger it goes crazy again and I have to restart the phone after every cutting of of the charger... it makes me really angry when the phone is only 4 months old and even the "okay" battery life isn't that good on this phone... God I just need to find a solution, that's insane...

THIS!!!!
the phones battery life was a big "ok i can just play a bit less so i can get through the day and IF anything happens i know it has fast charge so ok"
nowadays i have to reboot after EVERY charge....
p.s.
anyone that faces the same problem but WITH mai's security update? do we have any hope that it will fix that problem?

Not sure if it's a one-off, but I decided to uninstall the game "8 Ball Pool" by miniclip as it appeared on my battery usage stats when I'd not opened it in days. Since then, even after a recharge, the phone seems to be going to sleep as normal.
I'll monitor to see how things go but perhaps it could genuinely be a rogue app. It's a little disappointing that doze wouldn't block the keep awake requests - I thought that was one of the main purposes of it.

The same issue occurs for my Nexus 5X: after device disconnected from a charger, Android System process starts to keep device awake until next restart. As I understand from comments above factory reset does not help to solve a problem. Has anybody met the similar problem with custom ROMs/kernels?

It started with the latest update I think. It hasn't happened once ever before. I hope they already know what's happening and with the May update it will be gone. I don't think there's any other solution when you don't want to flash custom ROM and stay on stock... :/ we have to wait.. :/

Hmmm, sorry for offtopic clarification... as of now I'm little bit confused about Android versioning, especially it's unclear for me: whether you mean as latest update: 6.0.1 or april security patch or model build number (like MHC19Q, which is currently on my device)?

I guess it must be April security patch. Some kind of problem in the Android System app that comes with the security patch. I don't really know in this case, but as I've said, it hasn't happened once before the April patch

I rolled back to MHC 19J. The April MTC19T Build cut my battery life in half. Android system being the top culprit. Deep sleep never going over 80%. Horrible idle drain. Would drain 15% over night while i slept. Exact same setup as before, no new apps. SOT went from about 5 hours to not even 3.

MTC19T is May update. I've updated my device to it yesterday and the issue hasn't been fixed yet: a device is still kept awake by Android System after disconnecting from a charger. @ScumDroid, could you please confirm there is no such issue on MTC19J after rolling back?

Same issue. After running it for few months flawlessly, the Android System is keeping the device awake and only restarting it solving the problem temporarily. Charging the phone again starts the wake lock..
Most disappointing is it's the 'Android System' that causing the problem. If any app/game is linked to this, it should have been appeared as the culprit but unfortunately it's that 'System'.
Waiting for solution.

Samsung users are having the same problem.
I have found something on my Samsung Galaxy S6 in regards to 'Android OS' killing the battery. It might be the same for Nexus users, I've confirmed this on a Moto G 2015 running the latest MM update and on a Samsung Galaxy S6 Edge. By latest update, I mean the April security patch.
Check this and this.

Sorry for the late response mate. I have no issues with android system draining battery in MTC19J.

Nougat HUGE battery drain

Hi guys
Im having a huge battery drain since I'm on Nougat, and it's because of the android system itself. Not because of an app or whatever. Indeed, in like 3 hours I lost almost 40% only using Spotify.
Here is a screenshot -> http://imgur.com/a/24874
I know there is a ton of posts like that but I believe that battery drain-related problems are user specific, so..
And I'm on full stock. No rom, not rooted
Anyway thank you!

give us more information to help you. Rom? Kernel?

I'm on full stock ! No rom, not rooted, everything's stock

Here's what happened on my 5X, I got mine new about 2 months ago, had 6.0.1 and battery life was great with amazing stand-by time. Soon after, I got the final update of 7.0 Nougat, everything was fine and battery life was slightly better than before. About 2 weeks later, my phone started draining battery when idle with nothing turned on. I tried recalibrating the battery, doing a hard reset and nothing worked, it was still draining battery when idle (I lose about 25-40% over night every time) So I tried fixing this drain issue myself and here's what I did: I rooted the phone, flashed back to 6.0.1 only to find out that that idle drain is still there (I wiped cache and everything) When that didn't work I tried Cyanogenmod 13, the drain is still there. So I read about different kernels, and I flashed back to stock 6.0.1 with ElementalX Kernel and that didn't change a thing. I am currently on 7.0 rooted with ElementalX Kernel and my device is still draining battery when idle. I have done pretty much all that I could to try and fix this but no luck. I tried contacting people on the Nexus forums and the only thing they said is, it might be a software problem. But can't know for sure. If anyone can please help or knows what else to do it would be greatly appreciated. I should also mention that my fingerprint sensor died shortly after 7.0 update and I have no idea why. Btw every time I flashed a new rom, it was completely stock with no 3rd apps installed and still draining when idle. (Side note: I live in Slovenia, there are no google stores in my country)
Also there is no damage to my device, no drops, no water exposure. Should I take it to service to have the battery replaced? What if the problem is still the same? I need some help here..

I'd bet you a large sum of money that it's one of the Google apps holding the phone awake. Get a wakelock detector and find the culprit. All of that Google Location **** that they build into their apps just seems to run away and start draining battery. That's why I've permanently ditched having the Google app or Google Now Launcher on my phone.

I'll admit that I've used those apps before without a single issue. But every once in a while, usually after an app update, Play Services or Location Services would suddenly go rogue and it was infuriating to track down the issue. So I avoid those apps all together now as a precaution.

Same here.

What version of Google Play Services are you running? I believe a recent version (in the range 9.6.xx if I recall) had a genuine bug causing wakelocks.
The latest version (9.8.77) seems OK for me and the phone sleeps as before.

When I clean flash a new ROM I use Pico GAPPS which doesn't come with the Google App or anything and I just never install it from the store.

I did a fresh install of latest release of CM13 with the pico Gapps package, the only things I installed my self are gmail, drive and chrome, I also disabled all background processes in the developer options, set the animation to 0 and turned off all types of syncing, even before I added those 3 apps I was still getting idle drain. I don't know what to do anymore. I'm thinking of selling my phone and getting something else, but I'd still like to have the battery replaced just to see if it'll fix the problem although I'm not really sure it's just the battery's fault since more people are having the same issue. One thing is for sure, I will never buy the cheapest google phone ever again, my friend's 6p is running better and has more battery life on 7.0 than on 6.0.1.
EDIT: On this latest release of cm13, I got an android system message saying: There's an internal problem with your device. Contact your manufacturer for details.

Yeah I'm running the latest version (9.8.77) and today, out of no where, I started getting smacked with a ton of wakelocks from none other than Google Play Services.

Which cache did you delete? Like you wiped cache in TWRP or did you clear the cache of an individual app?

What kind of drain we are talking about here? Few per cent per hour or more? I had an issue with my old Note 4 recently, somehow it got wet and it was never the same. Battery drains in 5-6 hours. Generally, after you restore the software, there shouldn't be any drain, if there is, very likely it is a hardware issue?

Battery drain

Hello.
I've bought a G4 in March and only 20 days ago I've started to notice a odd and big battery drain. Android tells me it's "Android SO" consumption. What once drained like up to 5%, now drains more than screen. 20 days ago, battery lasted like 34h. With same usage now, turned 12h.
I've uninstalled the apps I've installed meanwhile, used it in battery eco mode and even on airplane mode, without any luck.
4-5 days ago I've installed Wake Lock Detector (no root, but with the right permissions) and Better Battery Stats. From what I understand from the reports, they don't blame any specific app but show thousands of wakelocks on Android SO. I believe sometimes it can be normal (for instance, when I run with GPS and music). Anyway, maybe the issue lies here.
What I find really odd is that those 2 apps say that the phone is awake more than 90% of the time. Like 1h of deep sleep only per full battery.
I could understand if someone says that it's the battery that had a great use already, but not only has 7 months of use, but also the phone behaviour changed (Android SO was never so high before, at least constantly).
Thanks in advance for any advice!

Suggest you check out and install the apps recommended apps on ✭[GUIDE][26-07-2016]Extreme Battery Life Thread(Greenify+Amplify+Power Nap)✭ at https://forum.xda-developers.com/android/general/guide-extreme-battery-life-t3095884
Read the OP thoroughly for each app discussed. The wakelock situation can be helped a good deal with Amplify and Greenify in particular - the paid versions - but I would also install AppOppsXposed - all require Xposed which requires root in order to be installed and I would also check out Power Nap to see if any incremental improvement.
You may a also want to run a malware scan ...

Thanks for the info. I checked it earlier, but most of those apps only run in root phones. I'm waiting for official Nougat in G4, mostly because haven't saw yet a Nougat image for this device without any problems, like camera not working, or such. I wouldn't mind to pay for apps that could work on this, but I want to avoid rooting. I guess I rather put Android 7, that has a bigger chance to even solve this problem, than root at this time.
Haven't said earlier but did a factory reset yesterday and device kept the behavior... I believe a hard reset would reduce almost to 0 the eventual malware problem.
No obvious alternatives for not rooted phones? Haven't this happened to someone else and been solved?
Thanks!

I had the same problem a few weeks ago...i was loosing ~30% of the battery at night with no wifi/data/gps etc. I tried everything...factory resets, different roms, greenfy & those kind of apps but the phone would not sleep. The last thing i tried was a factory reset and after i logged into my gmail account i set the phone as a new device...so no restoring apps and backups from my gmail account. Now everything is ok, my phone sleeps like a baby. I've read somewhere that it might be related with the syncing & backups....i don't really know, but you can give it a try.

Haven't tried that yet. I'll try to remove and add the device again, to avoid the pain of a new hard reset.
To have a reference, it was good to know an average percentage of other G4 deep sleep. If everyone has around 90%... maybe it's not a problem at all. The "sleep like a baby" is which percentage? Also, there are plenty babies that wake up hourly crying for a period of time...
Thanks for the tip!

My phone was awake >90% of the time(when screen was off), even in flight mode, when it had "the problem". Now things are back to normal...~2% awake when the screen is off.

Hello again.
Tried to reset a couple more times, tried to remove old phone register in my gmail account, but I wasnt successful.
How you did the
"The last thing i tried was a factory reset and after i logged into my gmail account i set the phone as a new device..."
?
Once it asks for my account, I'm not able to set it's a new device. I also did no restores... Is there a way to disconnect devices from Google account? I was only able to do so in devices I connected like one month, or more, ago, but not able to do so in the device I'm using at the moment.
One thing I did not try but that would confirm your thesis is to register device with a new account.
Anyone with an alternative?
I'm hoping LG really releases Nougat for G4 in 2017...

Today, the device returned to normality without any intervention. I can only imagine the following: since last factory reset I've disabled some apps I didn't used, like Google books, or Google music, but only yesterday I did a normal reboot (due to huge battery drain...). Eventually, some updates just took place after this reset. Anyway, even having imagined this theory, I don't believe in it. Wizardry, I bet.

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.

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.
