Purchased the shield tablet with controller yesterday. It came with 4.4 and seemed to run fine (wifi speed very fast etc) Soon after upgraded to 5.01 and the problems started..
There seems to be the Miscellaneous entry under the battery settings which is using around 40% of the battery according to the info. Battery drain seems to be quite fast.
Since then, today I decided to unlock bootloader and root the device which was successful. Miscellaneous entry does not seem to appear anymore
However there is the wifi issue that has occurred since I updated to 5.01. When the tablet goes to sleep and when I wake it up, connection is lost (and rather annoying where a game needs to download 1gb+ of data). It does also occur while I am using the tablet. Wifi sometimes just disconnects (and the entry on the wifi list for my router is showing as "saved" - clicking on connect, starts it up again..
I have checked through the settings and disabled the wifi off when sleep option as well as gps only for location etc, but still to no avail.
Has anyone encountered and solved this issue on lollipop? Or is this also an issue with 4.4? I did not use it for long before updating to 5.01 hence not sure If that problem would occur then (but seemed blistering fast for the hour or so when I was testing it)
I'm having the same issue. I looked on the forums on their website and it seems this is still a problem for a good amount of people. Can't find any solutions though. Thought maybe a hard reset might do the trick but that didn't help. Pretty frustrating...
Wifi connectivity seems ok when I am near the access point, but seems that the sensitivity somewhat has been reduced since the update (as the connection was more stable and reliable further away from the router on 4.4)
Hows your battery after rooting? Does it still drain horribly?
I have the same problem

THAT DRIVE ME CRRAAZZZYYYY!!!! the same happens to me everyday and I can't find anything about it online.. somebody please solve our problem!
I think I have partially solved the problem. The below is what I have done (Will at some point activate some of these options one by one and see which one would be the main culprit)
Settings->Wifi->Advanced Wifi - Turn off Ethernet override and turn off "scanning always available"
Settings->Wifi->Advanced Wifi - Keep on "turn wifi on during sleep" - Can turn this option off for some additional battery life
Settings->Controller->Disable "enable gamepad mapper" - From other sources it seems that this may be one of the main culprits in battery power sucking
Settings->Location->Turn this off (If wanting to keep on, leave it on GPS only)
Using the above settings, and charging the tablet approximately 15 hours ago, the battery life of the tablet has decreased by only 6% (and currently there is no - miscellaneous showing on the battery option)
There is still the issue with weak wifi (It works perfectly well when the device is near the access point) perhaps a future update may increase the sensitivity somewhat
One other important thing.. I decided to hard reset the tablet after upgrading from 4.4 to 5.01. This may help. Once this is done, then follow the steps above
Did miscellaneous ever come back for you? I did reset and changed all the settings and miscellaneous wasn't there for about 2 hours and then came back. Down to 50% battery with miscellaneous taking up 17%. I'm now wondering if this is an issue with the software or my tablet in particular...
For me, once I disabled the gamepad mapper, I no longer experience the outrageous battery drain issue, and misc. no longer appears in the battery status page and has not returned.

I didn't experience this miscellaneous battery drain until the most recent 2.2 update. When I upgraded to lollipop I did a complete wipe, rooted and unlocked the boot loader. When I updated to 2.2 I just flashed via recovery and wiped dalvic/cache.
I'm wondering if I need to do a complete wipe. I haven't seen any solutions to this, but it's strange that it just now started to be a problem for me.

The main culprit seems to be the "game mapper". - the system that maps the controller to touch screen controls. I guess perhaps updating to 2.2 turned it back on. Turn it off via settings and reboot and see if that makes any difference.

Thanks for the reply,
I turned the game mapper off via settings, and still got the misc. drain, so I froze the nvidia game mapper and a few other nvdia controller system apps via titanium back up and I'm still getting the misc. battery drain. I just wiped the cache, and dalvik cache 3 times, but I doubt that will do anything. It's looking like I will have to wipe and do a clean install, just seems so weird that something that didn't even change the android version number would give me this problem.
It's really annoying as the battery drains soo fast (like 20% just reading a book in my e-reader app)
before I wipe I just wanted to see if others had this problem with the latest update, as it doesn't appear too common I will do a full wipe later when I have time. I hope that fixes it.

I have the exact same issues as you describe. WiFi is about 25% of what it should be even standing right next to my netgear nighthawk. All other wifi devices work fine in the house. Disabled game mapper and my misc is still running the battery down. Tried wiping to factory with no luck. System UI crashes sometimes and the tablet freezes up constantly (especially when using Chrome and Google search). I'm thinking it could be Google play services related but not definitely sure.
Sheild LoLi screen changes orientation, goes black then to homescren
So seems you peeps having same problems I have experienced and troubleshot as well, but here is one I can't figure out...
Playing game (TaiChi Panda mmorpg) which only runs in landscape mode. I will be playing and all of a sudden tablet tries to change orientation away from landscape, the screen goes black (or has game shrunk and stuck in middle of screen) then will go black and puts me at my homescreen which is non-responsive and most times I have to hard power down. I've turned off screen/device rotation and still does it. The problem also happens with other apps and stuff at times as well. I've even turned all notifications etc I could cause thought maybe something was trying to interfere.
I have the screen flicker as well at times, feel like watching old black and white movie way it flickers.
Battery lifes went up with some tweaks found here (ty vm!).
Sorry to bump such an old thread, but has anyone figured out what it causing these issues on Lollipop?
About two months ago my old battery stopped working well and always turned off before reaching 0% so I bought a new battery off amazon and replaced it. Everything was fine. The battery lasted easily for a day and I didn't notice any problems. But yesterday my phone suddenly shut down. But it wasn't like with the old battery where the display just went black. Instead it showed the usual shutting down "notification" as if I turned it off automatically. When I plugged in the charger I noticed that the phone did show the lightning charging sign but was always stuck at 0%. That's why I assume that this problem is software related. Also when I am in the recovery I can unplug it and it won't turn off. Of course I already tried quite some things.
At first I cleared the cache partition - didn't work.
Then I downgraded from Android M preview to Android 5.1.1 using the flash-all.sh - installation did work but still won't charge or show that it is being charged.
Then I installed TWRP and wiped everything possible for several times and then used adb push command to move the latest cyanogenmod nightly to the phone and installed it - still won't show any change in battery level.
Do you have an idea what might be the problem and a possible solution?
Thanks in advance.
Have you tried another battery?
Hi!
Recently, my oneplus one has been misbehaving or acting weird. I'm running the latest CM13 (has been like this for the past 5 builds or so) and the latest boeffla kernel (also tried a couple of versions) here are the things it does:
Randomly freezes and turns off and won't automatically reboot (sometimes takes about 30 minutes before I can even hard reboot it sometimes the red LED is on and lots of unreadable partitions show up on my pc when plugging it in) and it will also enter some super battery drain mode where it can kill it's entire battery in less than an hour
the WI-FI randomly dies and won't reconnect until rebooted
Top part of the touch screen not really workig? Like the adress bars in browsers don't work but when I try to interact with the notification shade in that area it works fine...
Battery drain: not really an issue, just started happening today with nova launcher sucking the battery dry
And overall it's really slow...
I'm not sure if it's boeffla kernel or CM13 or the phone is just dead...
I tried to reflash a dozen times so not sure
Can anyone help me with this?
Same here but i have everything stock... Except Root and bootloader unlocked
Flash stock rom, make no changes don't even restore Google data just set it up as a clean device, and see if it's still misbehaving. If it is its hardware.
Hello all. My daily driver has been a rooted Moto G4 running RR (Oreo) for years now. As time has gone by, the stock battery has deminished to not lasting even a few hours (thus, it is always connected to a powersource). Since it is used primarily for work (Amazon Music App) w/ViperFx settings I've set, making any BT device it connects to sound outstanding, I'm in a dilemma... :/
The phone when pulled from power will randomly shutdown. (Guessing the battery application is faulty because of age, it calculates incorrect remaining battery life, shutdown point, eta charging , etc.) At times when this happens upon turning back on it will boot loop. The fix has always been to fully charge battery and it would restart as normal. Couple of days ago it has now permanently remained in loop, even with full battery charge or charger plugged in.
Searched for fixes and have attempted TWRP: cleaning cache, davlik/art cache, then rebooting. Removing SD Card, repowering. Selecting System then repair option, then restarting.
Hoping to retain data and settings without a factory wipe. Thanks for reading and assisting with a resution!
Hello everyone, I'm in trouble.
22 Ultra is simply eating battery at indescribable levels. Yesterday we went on a trip from work, I left my home with 100%. During the day I did not touch the phone, a bit of a camera but beyond that really nothing. My battery was about 40% after about 3 hours, with no screen use at all! On the other hand, a friend at work with Xiaomi came out with 100% and after 3 hours was on 85, and he did touch the phone here and there.
I don't know how that makes sense, and it's no longer clear to me what to do to solve the problem. I debloat, deleted and disabled a number of irrelevant apps but still, the battery is being eaten. How can I solve it? Please help me!
Draining battery so fast, 20% per hour while idle is not normal, so you definitely have a problem.
It looks that there are two possibilities here:
- Battery malfunction
- Some active process in the background that is using lots of processor power constantly.
If battery is damaged / not working properly, the only solution is to replace it. Still, this doesn't look like a case of duying battery.
If you have some persistent process running in the background that you can't get rid of by debloating, it can't be stopped by restarting the phone, and its not visible in the battery usage section, i would say that factory reset is the most effective option here, since you stated that you tried to deal with it in a various ways already.
You could also wait a bit until you get chance to update to OneUI 5 / Android 13, which should solve your problem, if it's software related.
Hope that you will find solution soon

I want to keep the factory reset as the last option....
Every single app that I don't need at the background I disabled from running in background.

Try to wipe your system cache.....it won't do a factory reset but might solve the issue while keeping your phone as it is.
Volume UP button along with the power button until you see Android screen
Scroll down with volume down until you reach wipe system cache and reboot
sometimes, it won't show up while you press the buttons....in that case, connect your phone to your PC/Laptop with any USB C cable and then do it.
Second solution, you can try Samsungs App Booster.....get an apk from the net. It generally helps as well.
