Battery drain on a brand new K1 - Shield Tablet Q&A, Help & Troubleshooting

So I picked up a Nvidia Shield K1 this weekend and this night I thought to see how effrctive DOSE was.
I went to bed with 96% battery and woke up to a 70% battery.
I havent tweaked anything in my tablet its completly stock.
I'm going to upload a screenshot to prove it. The tablet wws in sleep mode trough this screenshot and not being used as it wpuld sugest.
My question is, is there a way to solve this?
Sorry if my english is bad, and thanks to anyone whom can help me!

Hi,
Have you the Marshmallow update?

Yes I updated it as soon as turned it on
Sent from my XT1524 using XDA Free mobile app

I had the same problem but i think a factory reset solved it.

Strange, I haven't this issue. I have upgraded to Marshmallow once opened from its box, and unlock bootloader/root just after.
Maybe an application which blocks the doze mode?

Have you tried a wakelock detector? You should be able to track down what exactly is eating up your battery.
Check out GSam Battery Monitor, works for me!

Yes, GSam or BetterBatteryStats (link of the XDA post)

There's a thread on the NVidia forum about a similar drain, and in many cases the tablet also runs quite hot when it should be doing next to nothing.
forums.geforce.com/default/topic/904962/shield-tablet/android-6-0-update-battery-drain-by-miscellaneous-app-new-shield-k1-model-/
It appears to be a bug after the 6.0 update, it triggers the /system/bin/logd process.
You can check if you have the same bug by running adb shell with
Code:
top -m 5
(for 5 highes using processes) when it drains quickly, and look for the /system/bin/logd process.
It doesn't necessarily mean that it's the same bug, but considering the fact that quite a lot of people experience the same issue..
On the forum many users reported improvements when turning app optimization off, occasionally turning wifi off and on again and setting 'Keep Wi-Fi on during sleep' to 'Only when plugged in' or 'never'.
I have had some good results by selecting 'Only when plugged in' and by turning off 'Help NVIDIA improve SHIELD' in 'About tablet', but we'll have to wait on NVidia to fix this.

Same issue since marshmallow, runs hot with light use and huge battery drain. Been busy so haven't tried to debug or even reset yet but good to know its not just me.... Will unlock and root (will be a factory reset) soon, hope all will be fixed with this

Downgraded to 5.1.1 for the bad battery drain on marshmallow so I'm waiting to see if nvidia issues a update

I sufferring too the issue about abnormal battery drain, and I can't find a way to disable the touchboost (that clock at max cpu&gpu at same time)
so I searched for a kernel manager app compatible since 27th December when I installed my K1 with ota 6.0 , the only one that was updated is Ex Kernel Manager app (latest version 2.41 because 2.38 etc doesn't work) setting it on eco power mode or underclocking cpu to max 1224Mhz (if tablet is turned off or restarted must be set again), lcd set at 60% brightness but auto on, gave to me 26hrs. of active use on internet websurfing, movies and some light gaming at fallout shelter (2%) with wifi on all time and bluetooth for some.
Now I'm happy again ^_^
Regards

Hmm, I was actually hoping on keeping one of my devices completely stock/unrooted for a change, makes it easier for OTA's and takes less of my time on tinkering with it
That being said, when looking at CPU Spy it seems the CPU govenor isn't really flexible, most of the CPU states are sleep, 204MHz, 312MHz, 1044MHz, 1530MHz and 2218MHz, and little to no time on the other states.
I'm no kernel expert, but it seems to me that battery life could be extended without performance issues if it wouldn't immediately switch to high CPU states but the states in between...
Anyway, haven't had these abnormal drains since I changed the settings I mentioned earlier. Misc drain snuck a couple of percent yesterday, but lightyears away from what it used to.

I've done those changes and so far the battery life has improved a lot, one more thing my WiFi sometimes drops out of the blue does anyone else have this issue?

Haven't had a dropout as far as I know, but I did notice a WiFi performance drop once or twice. I was still connected, but webpages wouldn't load untill I'd reset the WiFi adapter. Those were also the times that a slight misc drain appeared.

I received NVidia shield v2 K1 with lollipop out of the box.
it updated via OTA to Marshmallow 6.0 and I had to revert back and block it from updating cos it was way to buggy for me, main problem was Wi-Fi/No internet issue. The tablet was a paper weight without internet.
N.B it did connect to the Wi-Fi. Rebooted my router, rebooted tablet, turned airport mode on/off , Changed frequencies and still nothing. My other devices could connect and have internet without issue.
N.B. It could connect to Wi-Fi, just no internet icon !

+1,
I had to set WiFi to Never on during sleep, I also use the debloater app to pretty much disable all Nvidia apps. My standby time has increased dramatically. But I hope nvidia releases an official fix.

Hi guys, I recently updated to 6.0 and have issues with battery drain during sleep. I see that I have a lot of wake locks by GOOGLE_C2DM. Attached is the export from GSAM.
First I thought it was Facebook and Instagram which had the C2DM services, I uninstalled the apps but still have the wake locks.

no, it is : /system/bin/logd -> this process gets stuck due to a third party error.
Just install OS Monitor and reset this Process if it runs into a high load.
nVidia will Release a Patch within the next days or a week, there is a announcment for that and a beta update for tester.

I install Deep Sleep app and set it to SLUMBERER MODE, now my battery only goes down 2% overnight. I'm happy with the results. Don't mind having notifications appear after I wake up device.

Hi,
Did this fix your problem permanently?
I bought mine 3 days ago, updated to mm 2 days ago and yesterday, voila, drain occurred while browsing pages I think, or some YouTube or streaming video...
I will try this today when I come back.

tiwlan_wq usage 48% and draining the battery

After getting tired of ghost call issue, I'm back on froyo but now new problem. The fkng phone dies when left untouched for few hours. I caught the problem to "tiwlan_wq" process taking 48% cpu time after being idle for few hours and then it totally drains the battery in matter of minutes. CPU usage showed tiwlan taking 48% constantly and my battery just drained out. It's got to do with wifi since at that time the wifi stopped working and the button was ghosted and i couldnt' connect or go to its setting page and only reboot was teh only option to bring it back on.
WTF LG can't have GB cuz of ghost call and now this froyo is useless as well. Seriously thinking of selling it but hv to wait for new quad core phones to come.
Do Use 360 Launcher 360 Guard or any power saver it happend to me once. The Power Saving App (360 battery guard) was unable to turn off the wifi module by trying to kill the process which made it hog the cpu. i think it happens when a process cant be killed keeps restarting.

I'm using go launcher. I had wifi protector app, wifi lock app both of which i have also uninstalled. Will charge it full overnight and then in morning see if this helped. BTW i'm using acura's v3 froyo rom. I have some batter saving stuff as well as uptime and cpu usage apps installed. Any software which can show the process down to root level since cpu usage doesn't explain what is causing tiwaln to keep at 48%.
Thanks for the reply btw

[Q] Help the charge sleep!

Hello all,
I'm running Tweaked 2.1 with the 5/24 PBJ kernel. Everything works great, except that I've found my phone won't deep sleep after I've charged it for the night. The only fix I've found is to reboot.
So, to be really clear.
I turn it on - deep sleep happens.
Use it all day, deep sleep happens.
Charge it overnight,
Disconnect and no more deep sleeping happens, it just stays at 100MHz and the battery drains that much faster.
So, my clever cell-phone-friends, any ideas?
Go this thread: http://forum.xda-developers.com/showthread.php?t=1179809
Download Better Battery Stats from the bottom of the second post. Install it, and then wait for the problem to happen again. When you see that it's happened, run BBS and select the options to view partial wakelocks since unplugged. That will show you what is holding wakelocks (preventing the phone from sleeping).
stats
Okay, so, here are the wakelocks after last night's charging.
Partial:
* ImapFolderPusher.....
k-9
12s
* RILJ
Dailer
7s
Kernel:
* "RXNET_MSL_LISTENER_WAKELOCK"
48 m 2 s
* "vbus_present"
2 m 21 s
And it records 51 minutes since unplugged.
I've looked for anything about RXNET... before, and found nothing. Is it maybe something realted to wifi? RXNET sounds like some sort of network receiving thing. I don't suppose anyone else has this problem?
I've also read about turning on the screen while unplugging and other hacky fixes, but nothing has worked for me. Those were for other phones, so I didn't really expect it to work.
In any event -- an further ideas? Thanks for helping.
You definitely don't have an issue with partial wakelocks, but kernel wakelocks seem to be a big problem. 48m of wakelock out of 51m is bad for battery life. I did a quick search and couldn't find anything specifically on that wakelock either. I'll keep looking and see what I can find.
Imnuts is the person to ask about this one.

Fixed!
So, apparently, freezing the Rx Networks PGPS downloader app causes that wakelock. Unfreezing it has let my phone sleep again. Odd that it waited until after charging to be a problem.

[Discuss] Standby battery drop: Airplane WiFi (50%) > WiFi +4G (3%)

I found airplane mode with Wifi on consumes a lot of battery (standby with screen off).
Below is the battery drop of one night (about 7 hours), using the latest official rom [G920FXXU2COH2] for G920FD.
- Case 1
Turn the phone into airplane mode and turned on the WiFi. About 50% battery drop for one night.
- Case 2
No airplane mode. Both WiFi and mobile networks are connected. About 3% battery drop for one night..
I don't know why this happens. Can anyone confirm that and tell me the cause to the battery drop. Is this a baseband problem?
Probably there is some app connecting to internet and because of Airplane mode it causes massive wakelock.
Could you post some wakelock stats by gsam or wakelock detector?
^^^ This. You need to find out what's causing wakelocks on your phone. It's probably an installed app.
It's possible you're running too many unnecessary apps in the background. Try searching on xda for this app called Purify. It showed I was running 17 unnecessary apps that I didn't use frequently. It needs root but it works magic. Let me know what you think. Btw it's not my app. Just something I stumbled on, on my search to save my battery life. I gained about 1 to 1 1/2 hours of screen on time. I have about 300 apps on my phone and I'm a rooted power user.
Oh, my phone used to lag from time to time when trying heavy multitasking. Not anymore. To each his own.

Battery Drain and Kernel Wakelocks

I've had this phone for a few days now and I notice some mean battery drain that happens from time to time. I dumped a Bug Report via developer options, and used Google's Battery Historian after leaving my phone unplugged and idle overnight after a full charge and reboot. The tool seems to show that the following kernel wakeup reason seems to be the problem and holding the phone awake for over 1.5 hours:
Code:
Ranking Name Duration/Hr Count/Hr Total Duration Total Count
0 Abort:Wakeup IRQ -1111803216 (null) pending 10m8s737ms 779.87 1h34m13.62s 7243
The only thing that looks remotely relevant is that on the tool WiFi signal strength became weaker when the above wakeup events started.
Has anyone else had similar issues with random battery drains like this and/or happen to know any workarounds?
Mine seems like it is always awake. Android OS has been keeping it awake for 8-9 while I'm at work.
I tried setting wifi to stay on when sleeping when plugged in, after a full idle overnight, I used my phone in the morning and the same issue came up. The ID above was different, but generally the same problem (IRQ with no description pending). Again, it looks to be wifi related based on the battery stats in Historian. I've rebooted, charged up and turned off wifi to see if the problem goes away.

You might want to try enabling developer options and getting a bugreport generated (which has battery stats), and then visualizing it in Google's Battery Historian to see if it is the same problem. Kind of convoluted, I know, but without root, I don't know of any better way to analyze kernel wakelocks (it isn't a partial wakelock issue on my device).
Last night I left my phone idle with wifi off and WLAN Scanning and Bluetooth Scanning off under Location Settings. The battery ran down only 2% over 9 hours and the Wakeup IRQ pending problem did not keep the phone awake!
I am going to try turning wifi back on today but keep the scanning off and see if that keeps this problem at bay. If not, I may use Tasker to force wifi off when the screen is not on and not plugged in.
The wakelocks seem to happen randomly no matter what my wifi settings are. Though I do think it is related to location settings trying to use wifi scanning.
I give up, there is no reason why a phone I just bought should be like this.
Maybe there are some apk wake up the system
@kumodog Maybe there are some apk wake up the system, you can reboot the system and kill all of application programs when you test it in night with wifi on.
After test, you can also use : "adb dumpsys alarm" in command line to find Top Alarms. it will tell you which alarm make system wakeup.

H.S. power control

I don't understand this feature at all. After reading this article http://www.xperiablog.net/2020/06/01/xperia-1-iis-hs-power-control-feature-bypasses-battery-charging-to-maximise-gaming-performance/ I thought it will allow me to play games for as long as I want without depleting the battery. I've tried charging with this feature turned on 2 times now, and both times the battery level was dropping., so where's that battery degradation reduction they write about?
Furthermore, H.S. power control supposedly prevents the battery from charging, but during both tests, Franko Kernel Manager was showing that the battery was charging, not in a usual way though. Speed was going back and forth between charging rapidly (as fast as 6000 mA) and charging slowly (as slow as 12 mA).
"Limits performance reduction and battery degradation caused by device overheating during charging. The battery doesn't get charged when this feature is on. Turn off this feature when charging". So you launch a game, go through the game enhancer's features, and see this confusing AF wording, which tells you the feature prevents overheating while charging and gaming, but at the same time tells you not to turn it on while charging and gaming.
I use this feature when navigating. I was happy that it's not only available for games. Worked well. At least battery level didn't changed after some hour drive. Didn't checked it with Franco kernel Manager.
You selected the App and the colored bar appeared when App was in use?

I've spent quite some time on customizing the phone, installing apps etc. so I'd rather not start all over again. Unless there won't be any custom ROMs for a very long time...
it is a bug. if you still have problem. or other people have a problem there a way to fix it without factory reset. if your phone running android 12 or android 11. BUT not lasted firmware(of the android version.). try to download lasted version of Game enhancer(i recommended version 7.x.x instead version 8.x.x, because it more stable on 7, but if you rooted or can install subsystem apk, you can go with lasted version and i more recommended to do so to get more feature), subsystem and monitor apk from apkmirror, dont worry all app have same Game enhancer logo. if you have android lasted android 11 or android 12 firmware, only download Game enhancer and monitor app, as subsystem has been set to persistent app. and cannot be updated. if you are rooted download all app i mention and install as system app then reset your phone. im using xperia 1 ii with version 7.0.A.1.20 game enchaner as my original version came with my firmware have bug and H.S does not work as intended. whoever updated it does fix the problem(you can see with most battery monitor app that charging switch from -x/+x to null or 0) whoever not installing subsystem and lasted monitoring app from cause :
1.powersaver or balance does not effect anymore(but switch to Power save allow phone to use 600-700mah more often, and performance while have same usage sometimes spike to 1000mah sadly the display stay at 60hz, this is not intended as using original app power are limitied to 400-650 while average around 480mah with 40hz display)
2.while congrats you can streaming from you phone now, unless subsystem installed you may only have 1 chance to screenshot thumbnail until you reset user data. as importing image or re screenshot not working without newer subsystem. but at least all stream function working fine as i test it for 1 hours nonstop(just make use you have atleast 20-30mbps UPLOAD as lower than that cause stuttering on youtube even on 480p stream)
3.it may or may not disable/bypass thermal throttling while gaming(cant confirm but on my phone using original apk will give me around 280gips max then down to around 160 or 180gips under 5 minutes while using update version will stay more than 300gips, on CPU Thrttling, same as 3d mark, while normal benchmark average, extended test will have better result than most xperia on same model with 99.5% stability and score around 1108 to 1106 from loop 1 to loop 4 with identical performance range from loop 1 to loop 20)
4.recording no longer work on sdcard as they change folder name and older subsystem still using older name, it just keep asking permission
5.on stream and record menu. there option for capture card. it does nothing, even installing another backend app. like audio app from G.E and other app, it still wont work, unless you are rooted and install all backend app as system app, whoever fearnot, you stil can stream your content via type c to hdmi like normal, but dont except you can get audio bypass or settings like xperia 1 IV have,
*again point 3 is unclear as for me performance from older bencmark are deference than now, but it is from era android 11, i can be sony fix thermal issue and performance from firmware and not this trick, but it does effect mine since i can just remove update and see instantly the deference and it may can on your xperia too
*i said both monitoring/monitor app and subsystem app. because it called that but apk file name uploaded as sony multitasking function and GE subsystem
here a proof for point number 3, and not it not with any mod(no fan cooler but no case either with H.S enabled)
Hello,
You can add custom apps to H.S. Power Control right?
Only supported apps or ALL apps installed?
Does that also work if you turn the screen off? or does the phone start charging as soon you you turn the screen off?
