[Nexus 7 (2013) General] acse1:
Weird behavior, i also experienced something similar when i left my Nexus 7 2013 idle for the night, about 8 hours and i'm still trying to see where the problem is as my steps written in a previous post improved my battery life, but not as much as i had hoped.

I left my tab to charge over night while turned off and turned it on in the morning. I left my tab at home while i was at work, so about 11 hours and when i came back home and checked the battery i was surprised to see that it decreased only 3% to 97% and than i started using it, not a whole lot. Before going to bed i checked it and it was at 90% and i left it idle over night. In the morning when i checked the battery level was yet again surprised, but this time not in a good way, it dropped 15% and the WiFi was turned off over night.

Using GSAM battery meter i saw that systemUI consumed 44.2% of the battery so i selected the standard KK launcher for Nexus 7 and not Google Now Launcher. Hope it fixes the problem.

I also need to mention that i have to users with full right on my Nexus 7 2013 so the battery may be affected by that, but i remember getting at least 3-4 days.
[Nexus 7 (2013) General] k3lcior:
I finally got rid of the WIFI wakelocks in deep sleep. :laugh:

Nearly 5 days uptime, with over 7hours screen on (auto brightness / min. @ night) and still 11% battery left.

ROM / kernel in signature. ;)

1.7Ghz, -50mV UV on CPU and -25mV UV on GPU.
[Nexus 7 (2013) General] coolsilver:
I've noticed a big decrease as well over weeks. Like others I notice a good 20% drain in a couple hours when I used to have that much over about 8-12 hours overnight. I've found one app that was using location and mobile data more but that was installed just recently and hasn't been any worse since the last system update months ago.

I'm seeing over 10 hours the OS is keeping it awake 36% of the time (7 hours+ awake time for the OS), Screen 10% about an hour. Something is up here. Maybe I will run a test backing up, system wipe and see how long it lasts off full charge bare os and no google services logged in.
[Nexus 7 (2013) General] acse1:
I'm still experiencing battery drain after changing to ART, not as much as on Dalvik, but still 20% over night. I've used Wakelock Detector and GSAM Battery monitor (my Nexus 7 is rooted and with the original OS), but haven't found what is exactly draining the battery.

The silver lining is that in SafeMode there is no battery drain, but i still don't know how to fix the issue.

I'm going to try to put the KK 4.4.2 factory image and see if the issue persists.

Does anyone have some other ideas i could try?

Thanks.
[Nexus 7 (2013) General] coolsilver:
This is just silly. No way is this normal...
[Nexus 7 (2013) General] coolsilver:
I did some tracking down on mine with the OS monitor app. Looked at log for system_server process. Tons of CPU time but said it was asleep. Log ever 30 seconds had an error for the location service. I think they patched some issue with the play services but now the OS location listener is broken.

2014-03-05 10:04:07,ERROR,LocSvc_eng,W/int loc_eng_inject_location(loc_eng_data_s_type&, double, double, float): log_eng state error: instance not initialized

I have gps off and location to battery save. But still tries to get location with no other entries about calling for it.
[Nexus 7 (2013) General] ArtieQ:
Is it normal that Android OS (not Android-System) is at 30% or more? If I check inside that it says CPU total 7 minutes and Keep active is at 5 hours..
[Nexus 7 (2013) General] acse1:
I've just put the last factory image on my Nexus 7 and it seems that the battery drain stopped over night, but i had location and WiFi turned off. I'll keep testing it today and see how it handles.

Maybe the issue was caused by multiple updates.
[Nexus 7 (2013) General] coolsilver:
It lists as Android OS in battery usage and in OS monitor but lists a few processes as Android OS.

Battery

Hey guys, i've bought a nexus 7 2013 couple days ago and instantly updated to 4.4.2. (never used it with jelly bean) it's brand new, no root, all stock. Did you think that this is normal? battery drains from nothing i've disabled wifi when locked,auto sync is off and still... so is this normal for a nexus 7 2013?
[Nexus 7 (2013) General] gmaugham:
Uninstalling Skype fixed my issue. I went from 6+% per hour to my previous 2.3%.

Verstuurd vanaf mijn Nexus 7 2013 met Tapatalk.
[Nexus 7 (2013) General] saneofficial:
2.3% /1 hr is still unacceptable for idle.
[Nexus 7 (2013) General] coolsilver:
Today so far 5 hours and 83% with location set to device only, gps off, no wifi on. But Android OS still shows over 50% drain, Tablet Idle is at 8%

Better.... but 83% was about how much I used to have after 10 hours of no use.

I'll remove skype and see if it helps. I don't see how it could cause such an issue when I have it on my GS4 as well with 4.4.2

I just now turned off the wifi location scanning and wifi during sleep options. If that doesn't do it I am not sure what to try.
[Nook Color Q&A, Help & Troubleshooting] robbieas:
I've installed CM7.2 and then flashed the 20110828 CM7.2 gapps. When I try to setup my Google account, it always tells me the password and user name don't match. I'm definitely using the right user/password though.

I've tried this with CM7.2 and MiRage. I've tried installing the ROM first, booting, setting up WiFi, making sure the date/time are right, then going back to CWM and flashing gapps... I've tried flash both at the same time... I'm clearing system, data, cache, dalvik, when I start over.

At a loss here... had this working a while back, upgraded to CM10, now trying to go back. I swear I'd recall dealing with this 2 years ago when I first installed CM7, but can't remember a fix. Any help is appreciated!

hello to everyone, I am "brand" new to this site, therefore forgive me if I am in the wrong space to ask the following.....( as a matter of fact I have already made a mistake in posting it twice by mistake ..wont happen again).

I own an iMate JasJar WM5. I had a first one a week ago. Open it, brand new, charge it, canceled skype and Ca antivirus ( useless) installed SK tools to monitor and better manage the overall performance of the device and found under the folder Invalid Registry Entry a huge number of strings...very strange indeed, well, whatever it was the device couldn start up after few hours pf usage therefore I brought it back to the shop and got a new one... I THOUGHT ALL THOSE REG ENTRY WERE the cause of the device problem..opened the new one, charged it, unistalled and spoft reset again skipe and Ca antivirus, instalòled SK tools and have seen the same huge numbers of invalid reg entry...The device this time works well, no prob at all...SO FAR.. I have it for 2 days, so it is early to say but what really annoys me and WORRIES me are all these strings which I will post (few of them ) here below to see if anyone can explain me what they are, what do they mean in practical terms , if I have to consider the device again "broken" or gonnabebrokensoon, ....what leave me suspicious is that the same things happened with 2 new devices.

here are the strings and the messages copied from SK tools..thank you to anyone for his help or suggestions:

This errors has been there for quite sometime, since the day I have my Hx4700, Wizard, and now Hermes.

NO ONE, not even PocketPC Thoughts, HowardForums, or XDA Developer know about these invalid registry, not even the developer of SK Tools. I've searched Google for EACH of this registry entries back then, but yield no result. Unless someone have better Googling skills, do share with me.

I tried to delete one of them, and my Wizard was giving so much error and instability I had to Hard Reset. HOWEVER, on a second try after the hard-reset, NOTHING happened when I re-delete these invalid registry.

Go figure...
[GT540 Optimus General] anijatsu:
I've got a few problems lately and I have no clue how to go about fixing them.

I'm not sure when it caused the problems, but I'd like to keep settings and apps that I've gotten now. I see constant factory resetting as a workaround rather than a fix. The last thing I did before I got these issues was plugging the phone with an USB cable to a Windows XP computer without installed drivers for the phone. There was a movie running in the background in MX Player and I noticed that I'm unable to unlock the phone.

First off, the lockscreen is bugged. When I try to unlock the phone the screen stays blank, but the button LEDs are glowing and vibration works if I hold the power button, suggesting that the system is still working. I tried turning the CRT animations on/off to no avail. An interesting detail is that the lockscreen that appears just after booting up the phone shows up and works fine.

The second problem I have is some of the GUI being glitched. It occurs to for example the startup lockscreen and power menu, as in the attached picture.

To make sure this wasn't a hardware fault I did a complete reflash of the phone using KDZ updaters and there were no glitches in stock ROMs. After installing back the recovery (Clockwork 6) and restoring the backup of this SDSL4 the issues are still present.

Is ist possible to get it over build.prop ? I had read that on an other webside..

[Galaxy Tab 3 Q&A, Help & Troubleshooting] hfase:
Yeah IIRC there is an app on here somewhere to enable it for you. Command line method will reset after reboot. You would either need to decompile one of the system apks or wait to see if we can get CM for me to patch and build.

I have the diff saved on my desktop, it's literally a change in two lines of code. I have even compiled my own flushable roms for other devices to test it, and it works good... ;)

[Galaxy Tab 3 Q&A, Help & Troubleshooting] hfase:
Well. If you want somewhat stable results you can try both of these threads.

The first is manual and the later is the app. I do know that doing this manually will be reset after boot, I am not sure if that is the case for the app version though.

App Dev thread: http://xdaforums.com/showthread.php?t=1824066

If you want more baked in results (enabled MU by default without app/cmd) then the following edits need to be made to either a complete source tree or the de-compiled files mentioned.

The above method outlined in the git diff I have tested on a few (officially supported CM devices) with decent success. I might help port CM to this device if it can be profitable for my time, and from there I can roll out unofficial MU builds for you all.

Hi! I have this problem only when I restore from a nandroid which I had made before installing the unofficial Cyanogenmod rom for my Samsung Galaxy Note 3 N9005. The Backup was made on the 29th of december which is only a few days ago (Since posting this) and It just doesn't want to boot. I've left it like that for 2 hours and still it has not booted. Is there something wrong with the nandroid or the phone? Oh and if I flash a pre-rooted stock rom which I have downloaded and flash it withouut wiping the data it's all there but then I encounter a "com.google.process.gapps has been stopped" message that doesn't dissapear when I tap ok (already made a thread about this so i'm not gonna type alot about it). Is there something I can do to make it boot again?

I bought a hummer phone via aliexpress. After a while I noticed, that i can't upgrade the system, the android system is having some problems...does anybody have the same phone or problems? what can I do?
[General Questions and Answers] EHR11:
Hi All.

I was trying to use some apps to emulate touchscreen in order to play with my gamepad. The problem is that My tablet (A generic one... Known here In Argentina as NOGAPAD 7 "White edition") seemed to not have root access. So, I decide to give it a go on SuperOneClick (So far I've tried with my LG Optimus ME Succesfully, so I was pretty confident about It).

Imagine my surprise when I discovered that SOC said my tablet was already rooted, and aked me to re-root :confused: . "Well, might just try and see if it works" I said. The proccess was completed, but when I checked the proccess notifications, It was two fails regarding the install Of SuperUser. It was something like SOC couldn't write data, or something (Sorry for the missinformation, I forgot to capture a shot of this in the moment)

Rebooted my tablet, I tried some "root-requuired" apps. Didn't work. I was pretty upset about then. I searced a little bit deeper, and stumble across this app called "UnlockRoot".

"Excellent, let's try". Guess what, The same "already rooted" thing again. I surpased this and tried to "re-root". This time the device rebooted itself, and SuperSU was installed, so I figured out that this time it had worked. Wrong. Allthe apps didn't get the root access they where looking for.

My specs are:

• Proccessor: A20 Dual Core (1.2 Ghz)

• RAM: 1 GB

• OS: Android Jelly Bean 4.2.2

I'ts something wrong with what I'm doing? Or the tablet? Please let me know, and if you need some caps I can manage to get some. Thanks for reading.

Looking forward to your response :o

[Q] Do apps require special coding to utilize X-Reality & Triluminos technologies?

Straight forward question in the subject.

The stock Sony "Albums" app vs. QuickPic or similar 3rd party app, will Albums display the pictures better because it calls specific functions or utilizes code to call in X-Reality engine enhancements?
[Xperia Z1 Q&A, Help & Troubleshooting] xasbo:
Unfortunately, I can't give you a straight answer. Here's an interesting video on the topic, though:

[youtube]M51KPcYKZP8[/youtube]

Specific functions would explain why only the Sony app is taking advantage of the optimizations, but I haven't found any hard evidence to that end yet.
[Xperia Z1 Q&A, Help & Troubleshooting] Wiltron:
I'm just wondering if I should TiBu the Albums app and hide it from updates, and use QuickPic or similar since IMHO it's superior and less bloaty. I don't want to drop all that rich buttery goodness though that is X-Reality :/

So conflicted.. can anyone else chime their $0.02 in?

If you lose X-Reality you will never notice a difference. I have it switched off. I use many "Albums" and the pics look good to me like with X-Reality and stock Album.

hello everybody, thanks for coming out tonight!

the problem:

no matter how much i leave my wildfire charging, it DOES NOT REACH 100% and the percentage that it reads at most is 70%

this problem occurred after i used Battery Callibration app to calibrate my battery (i tried to calibrate cause i thought that it reads wrong percentage)

is there ANYONE helping me out please?

:(:confused:

p.s. i have root access and i have tried hard reseting (bootloader clear storage) and format \cache \boot \system \data in recovery and all......... nothing helped! i also tried several roms including cm7.2 and RUUs. non of them helped.

That is a hardware issue,most of us including me face this issue.I'm sorry,there's no real solution for it.
[Wildfire Q&A, Help & Troubleshooting] farrokh_sha:
thanks for the answer dude:)

how come this is a hardware issue? we went through a software-related procedure and now it is about hardware!? i mean we didn't change the input voltage... did we??? it's really odd to me.

did it happen for ur phone after using Battery Calibration app?

what if i change the battery, does it make it right like before?

another thing to consider is what Battery Monitor Widget Pro shows. it says that my battery at most is filled with 900 mAh out of its 1300 mAh nominal capacity!!

what exactly does this app do??:mad:
[Wildfire Q&A, Help & Troubleshooting] Wasimk32:

and in clockworkmod recovery i also tried removing battery stats, wiped data/factory reset, wiped cache partition, formated boot & system & data & cache. none of them helped!

As others say, I also expect it to be hardware related, perhaps the app somehow changed certain voltage parameters and overburned/underburned/eated your battery cappacity. But I just stumbled upon this, and thought you might as well give it a try.
