bad all around lag after 4.4.2 update

After taking 4.4.2 update last night phone has massive lag. All apps are affected. Have done factory reset, cleared cache, Uninstalled and disabled various things. No luck. Anybody else experiencing. Phone is not rooted.

I would factory reset everything. Start fresh without apps . I've noticed on 4.4.2 leak nc2 I had some lag if I froze some of the Verizon apps unfreeze them and had no issues after. Hope that helps only thing I turned off was caller ID but I'm rooted so factory reset is easier for me

Tried it. I had a brief few minutes lag free but then it came back.

Is this happening before all your apps restored, if you are restoring them? Or are they in the process of downloading and installing?

Thanks for the reply. After the update it ran its little app optimization process and then begin installing various updates. I assumed lag was normal then, but after several hours was still getting the lag. Last night the lag decreased before I went to sleep, but this morning it is back. I have developer mode active and I have the CPU process overlay and the one item I see spiking with high CPU usage is the the kernel process kworker. Did I get a bad dose of kernel?

The only thing I can think of is, if you want to try it, run a factory reset, do not restore any apps and see if things settle. It could be an app that is causing a conflict.

I know this may sound silly but take out your battery for about 30 seconds. I have this problem occasionally and when it occurs my phone is extremely hot. I have to shutdown... pull battery... and all is good until it happens again. Happens to me at least once a day.

Removed my Spigen s-view case and lag stopped almost immediately.

Same problem here. All around lag from typing to within app use, terrible slowness plagued my device. Removing s-view case removes all noticeable lag immediately. Using Spigen s-view case as well.

Update destroys battery life?

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

Yet another battery drain issue

Hi, folks.
So I've installed an update yesterday (I think it's the security update from the first of January)
http://imgur.com/d0IkGXV
and my battery immediately went down the drain. These are the usage statistics during the night:
http://imgur.com/VwFGP2k
http://imgur.com/qO66N4F
From what I can see, the phone has been awake the entire night. That can't be normal, right?
Since this update has been around since January, has anybody else had these issues with this update? Any solutions?

Same model,same update, same issue.Others say that battery life increased with this update, but for me not.Factory reset didn't help. Maybe Google f*** services again.

I'm on N910C and have the latest update for my region (DQA1). Although my battery life hasn't been as good as I've seen in the past, it's definitely not as bad as what you're seeing and my phone doesn't stay awake all night. I do use Greenify Hibernate and Aggressive Doze, so maybe that's why - or perhaps you have a misbehaving app somewhere.

Try to clear data from all Google services, playstore etc reboot into recovery and clear cache.. if the problem still remains then the only solution is factory reset.. there's an app causing this your cpu/ phone is a wake all the time

Mine doesn't do this, there must be something misbehaving on your phone. There are steps you can take such as deleting cache/data from G.P.S. to try to solve this issue. Search the forums/web for other suggestions.

First thing to do it, just do a factory reset. Install only the MUST have apps one by one over couple of days. Watch it overnight. Since there has been some security updates, its possible that I broke some code on some non google apps installed on your phone. First try to isolate that app. I am pretty sure that google has tested the code on all google apps before it released it.

Samsung DeX Home battery drain

Hi There,
According to GSAM Battery Monitor Pro, I'm getting a huge battery drain from Samsung DeX Home: 21.2% of my app use.
Anyone else experiencing this?
P.S. I do not have a DeX dock and never put my phone in 1 either.

I get that sometimes too. I think it is a mistake by GSAM. It might actually be Android System. Whenever I get DEX using a lot of battery I don't get Android System. When I don't have DEX showing up Android is a pretty big chunk of the app usage. Also, I have DEX disabled using Package Disabler Pro, so it shouldn't be using any battery.

I got the same here, dex almost always the biggest consumer of battery, i agree it might be refining to andriod system..

Yeah, I have the same problem. Also had it disabled but it's still showing as battery draining.

Just starting a thread about the same thing, but this one popped up.

Same Issue - Need a fix
I'm also having the same issue. It gets so bad sometimes to the point where the UI is totally frozen and I cant do anything except for a force shutdown via the power + volume down button combination.
The frustrating thing is that, for work I am trying to debug battery/performance issues with the app I am developing and all of my results and tests are tainted by the app GSam labels as "Samsung Dex Home".
Hope someone finds a solution! I cant even use my phone as a test device for work anymore because of this and every couple of hours my phone locks up entirely and I am forced to restart it.

It is not the same issue. What they are talking about is simply gsam listing android system as dex, which it has done since launch and isn't a performance issue it's a labelling issue, and is one of several problems with gsam which likes to forget is has the right permissions half the time. Your problem seems to be something else. having gsam label system as dex does not cause freezing.

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.

Play services also cause these type of sudden battery losses.
Try downloading latest play services apk from apkmirror . Latest one is
"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 .

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.

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?

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.
