Battery Drain @ 8.9 Tab ... WiredAccessoryObserver Wake-Lock - Galaxy Tab 8.9 General

Hey,
my SGT 8.9 16gb 3G with stock 3.2 Rom XWKK4 has a problem. BetterBatteryStats said, that "WiredAccessoryObserver" is permanently running, when the phone is in standby. I think because of this I lost 1% Batterypower per hour, even with Wifi and 3G Off...
I wiped the tab but it doesnt help.. no thrid party apps.. Do you have an Idea? I want to use stock-rom because of warranty!
please help me!
thanks and greetings,
Benni

Hi,
Same issue here, but on Overcome 2.2.0:

Some days ago it even drained >3% per hour, spamming the logs constantly with such entries:

This however could be resolved by wiping user and system cache with Titanium Backup.

just a theory, but it thinks you have headphones plugged in so it kept the device awake.

hm, no headphones connected

on my old captivate i was flashing early versions of ICS and it kept thinking i had headphones plugged in, and when i plugged in headphones it thought they were removed.

Anyone know how to turn the headphones off? I tried an app called volume booster and it screwed me all up
Thanks

Dug around some more.

Looking at your screenshot, 12 minutes of a wakelock on a 1 day + charge really isnt that much.

[Q] SGS to be used as pocket heater? Wifi eating too much?

Hi guys,
I'm having problems with battery like everybody else.
I'm not a n00b about this and I have no crazy apps installed (I'll attach the list of apps I have)
My rotation sensor is off,
AutoBrightness is off,
HSDPA is turned off,
UMTS is turned off,
EDGE is always on and AutoSync is always on.
I have only 1 widget running that is Battery Monitor Widget.
Using SpeedMod K13C 500Hz with no tweaks applied and no lagfixes applied, I'm having huge battery drain randomly, most probably when I switch network connections wifi-edge-wifi-edge.
Here's my RomKitchen log file
http://romkitchen.org/logs/VgOonoWjJx.txt
Here's my installed apps list
http://dl.dropbox.com/u/1339016/SGSInstalledApps.txt
Here's a screenshot from my last battery graph (this rom is installed almost 20 days ago)

As you can see, my battery instantly dropped by huge amount.
All I did was wake up the phone,
toggle Wifi ON,
open Skype,
login, call a contact for 3 minutes,
logout Skype,
toggle wifi off.
What I want to know is, if Wifi driver patch needed with this setup? Will it make any difference? Maybe it was not my wifi but my screen?
I desperately need advice on this.
Thanks guys.
Uninstall Skype and test it. Its running even when logged out and eating too much battery. Have tested it withhero and system panels monitor. ..
The battery draining that much all at once strikes me as very odd.
Off the cuff that seems like a reporting error to me. Try recalibrating the battery a few times the old fashioned way (drain fully, charge to 100 while off, wipe batt stats, rinse, repeat) and see if it happens again.
Good luck.
Thought about trying totally stock for while I tried different kernells and found I still go back to stock best ive had is js5 getting around 45 hours on stock against charging twice aday with modded phone

Calibrating battery and freezing skype with titanium backup seem to fix problem.

Might not be your power bank, try using BBS to find out
After a day i can confirm is NOT the power bank. since this happened in the past 3 days
i used Airplane mode all the night to see if some a is Wakelock my phone and got just 3 % of battery usage with the power bank attached, so i manage another test since BBS told me is Android System RIL or something like that.
Second Test: Disabled 3G+ Connectivity for 2 hours and enable just GSM 2G and just got 4 % dropped ( i make a few calls and used whatsapp so is OK), i think is 3G becuase where ilive is outside the city and recently we got a heavy storms (causing shoutdown of the nearest anntena) i have low reception rnothing and 3g running so i think my phone is using more battery trying to acquire more signal and 3G support.

[Q] Battery drain on unrooted phone

My MotoG 2014 with Lollipop 5.0.2 is unrooted, I have read other threads about this problem: I've installed Lollipop on it from brand new phone.
The scenario is still that there is no way to track down who is draining the battery on unrooted Lollipop? :crying:
I have Google position on, wifi on, bt off, 2 sim with one active for data.
Yesterday the phone lied on a table for about 11 hours before taking the following screenshot, I may have used it (in that 11hrs) for less that one hour not continuously

How can I find the responsible app? Should I start powering off Google position?
Try to reset your device ..! This should fix it..! And that's not a huge drain in my opinion because WiFi , 3g , and auto sync is on always so its Normal 11 hrs standby and still some juice is remaining that's great actually..! ☺

If with reset you mean Factory Reset, I will leave that as last because restoring an unrooted phone is a pain (to be polite! )...
Right now I've followed the (few) steps for unrooted phone from http://forum.xda-developers.com/moto-g-2014/general/guide-how-to-best-battery-life-moto-g-t3049970
configured localisation as "Battery Save"
removed "my face" from Smart Lock
installed Greenify and hibernated (manually... ) a few app
I cannot leave the phone in standby for long time now, I will see on next weekend!
BTW: from my point of view 80% used in 11 hrs standby is not great...
The above steps didn't change a lot the battery drain...
With "App of the Day" I got Battery Booster, actually I'm using it only to its statistics: I do not know how much I can trust them but so far the only apps that are using battery even when the phone is in StandBy are:
System UI
MotoCare
I can understand the first, but what about MotoCare?? Is it a vital component? Can I safely disable it?
I do have only Motorola Alert activated and running, but I can disable it! Both Assist and Migrate are disabled.

Catastrophic Failure?

I've had my SM-T810 (Tab S2 9.7, wifi) for four or five years now. A year ago, half of the screen began flashing brightly if I tried to use it on low brightness. To solve this, I turned up the brightness a bit and used the app Darker.
Over the last few weeks, things got much much worse. The tablet required more and more brightness to avoid flashing, it would stutter when playing videos, and responsiveness was slow. Every so often it would lose WiFi connection when my other devices didn't have trouble connecting.
Today, there has been some type of catastrophic failure. I was watching a video, when suddenly the video stuttered, froze, and the tablet became completely unresponsive. None of the buttons worked at all. It would not turn off. After about 15 minutes, the screen began its old flashing routine...and then something new happened: the flickering was joined by colorful lines, and about five minutes later the tablet shut itself off. It had become quite warm around the volume rocker/card slot area.I can't turn it back on, but if I plug it in, it shows the battery percentage. The tablet has never gotten wet, and it hasn't been dropped recently. Any thoughts? Thanks in advance!

Is the battery indicator dimmer than normal? Normally I would just assume at least the screen is bad, but since the charging indicator seems to work? Perhaps you should try download mode? Odin over fresh firmware? (You will lose data on the tablet though)
No, the battery indicator doesn't seem dim. I'll have to try your suggestions. I'm starting to think the motherboard is bad, and that would help me determine if it is or not.

Maybe some files in EMMC corrupted? Then if ODIN works it might get it back to life.

Question Important battery drain not understood

Hello all,
I recently buy an OPPO find X3 pro and I'm really annoying with battery life. I could not succeed to reach more than 3h of SOT and would like to know if it's normal.
I already perform a factory reset without success (back-up and restore from a PC). I don't know what to do know.
I've installed GSAM and allow "more stats" with ADB and notice that Android System is the most battery consumer but I don't know if it's normal. In idle, power consumption is acceptable 3-5% overnight but as soon as use it I see battery level decrease rapidly.
I've also a Galaxy watch. At the begining I saw a high drain from "watch plugin" but I authorize it to run in background + no battery optimization and it seems Ok now.
Does anyone have a solution to help me solve this problem ? I really like this new phone btw (after my old OP6T) but the battery is really awful...
Thanks in advance !
Below some screenshots :
2h20 of SOT only and 35% left

Hi,
I had the same problem. Did the following:
1) Reset to factory settings;
2) Restarted the phone;
3) went to Settings > Battery > More Settings > Optimise battery use > set all apps to Auto-Optimise.
If you want to test if you probably have a faulty battery you shoud do the following:
1) charge your phone till 100%;
2) restart the phone;
3) disconnect it from the charger;
4) switch on airplane mode;
5) leave the phone unused for 8-10h.
If the battery drops bellow 93%, you have a faulty battery that needs to be replaced.
Bare in mind that this processor is very power hungry, nevertheless OPPO should have predicted it and pack with the phone a, at least, 5000mAh battery.
Hope it helps!
