[Q] Screen Turns On Randomly Without Touching Phone

When I leave the Nexus 4 on a flat surface with nothing around it, it will randomly turn the screen on, wait the 30 second timer, then turn back off.
I did just install 4.2.2, but I hadn't used it enough before to say if it only started since then.
I'm currently unrooted, though unlocked the bootloader when I first got it so I do plan to root soon, would flashing a custom kernel like franco kernel possibly fix this? Or would this be a problem in the rom or a third party app?
In BetterBatteryStats I saw 2 Kernel Wakelocks that seemed to have a high ammount of wakes.
(Screenshots Attached)
And here's the BetterBatteryStats Dump File: https://www.dropbox.com/s/dbc2vn3littc0fp/BetterBatteryStats-2013-02-21_054751350.txt
Any help would be highly appreciated, thanks.

Possibly a third party app.

Err I meant like, it keeps turning the screen on and off - like if the charger is disconnecting itself.

Sounds almost like the charger has a short or something.

It does that with all sorts of different cables and chargers. Think I might have a loose USB port?

Maybe it's linked to the Daydream feature?

Not sure, guess it's possible, but even if it is lose I wouldn't expect it to effect it once it starts unless it gets bumped.
Also, what is the temp of the battery when charging? Not sure if it's true but I've heard that if the battery is over 40c it won't charge properly.
If you want, here's a really nice widget with temp on it: https://play.google.com/store/apps/details?id=ccc71.bmw
I would just be careful with anything to void your warranty until you figure out whats causing the problem, as I've heard a lot of stories about bad batteries, and shorts in usb causing the red light bug (For lack of a better name).

Thanks for the link. I actually looked through the 'must have apps for the N4' thread under themes and apps, and Goku80 had posted a link to a battery meter that I just downloaded and installed moments ago. I have yet to see what the charge temp is, but I will report back tonight. Idle temp is around 25*c from what I've noticed just now.
The only thing I've noticed with temps so far is when I have my phone pulled in and I'm watching something on the phone. The phone gets really hot, and the system starts to lag badly. I would assume this is a fail-safe for the battery to not overheat by downclocking itself, but this is only a theory.
As for the red light bug, I saw my phone drop from 28% to 4% instantly out of nowhere yesterday, with no warnings. I immediately pulled the phone in, and watched the battery meter jump to 30%. According to the red light threads, I think it's a software issue with the phone shutting down completely when it thinks it's out of battery to prevent damage. Hopefully we'll never run into that issue ourselves.

Massive battery drain and an eternity to charge

Hi,
This past week, my G2 has had massive problems with the battery draining when I have been doing basic things like web browsing etc.... I can literally watch the battery drop %'s every few minutes... the phone also gets extrmely hot up the top of the phone around near camera, it gets to about 50 degree... and to make things even more worringly it takes all day to charge to full, instead of it charging to full in an hour or so it will barely get to 50% overnight..
Does anyone have any ideas what the hell is going on??? It's running stock EU KK ROM

I'm having the same issue. For me it seems to be triggered when I connect to bluetooth in my car. Once the battery drain is triggered it continues even after I get of the car. I've gotten in the habit of rebooting my phone every time a turn off the car. A major pain but it works until I find a better solution. I've been thinking about wipping the phone but I don't want to go through the hassle if I can avoid it.

First thing I guess would be to try a battery stats app (Gsam for instance) and have that running from a full charge to see if anything is running without your knowledge.

Not even with a separate app, did you guys take a look at the "stock" battery stats?
I had once a big battery drain that was caused by the media server.
If I helped you, please thank me

Ive currently tried every battery stats app i can get my hands on lol..... I've gone through the 50+ battery guide using titanium back up.... I've disabled startup programs.... Geez even Sonic the hedgehog Ep2 was for some reason just always doing something and i never touch it lol.... Anyway I'll keep a close eye on it but i still can't explain the long charge times.... Maybe something will come up
Yeh I checked stock battery stats, the main hog seems to be bluetooth when it's not even switched on :/

What cable you using? All cables are not created equally. Try the cable and charger the phone came with. if that's not it try a different cable.

Im using loads of different cables...
I actually *think* I found the very unlikely culprit.... Google Chrome Camera!!!!!! Someone else commented on the exact same problems as me on the Play Store... which sounds about right because I've had the charging probs about as long as I installed the app.... So I've removed it and hopefully thats fixed it

I could see the app maybe causing the drain but I think it highly unlikely it affecting charging. I still like the cable idea for your slow charge. Go find your white one the phone came with and try it =)

OTA Update 2.4.1

OTA update has come 2.4.1 nd i am very happy that they are giving updates and solving the issues nd bugs..but... nvidia will give any android update ever or we are now stuck on 4.4.2! ?

Nvidia has stated in a e-mail that we will get 4.4.3 so don't worry

Thats great thn but they have stated when because now android 5.0 L has released

Android L is still in development and we haven't had 4.4.3 or even 4.4.4 so lets give Nvidia some time!

I'm glad That Nvidia is putting out all these updates. I really really want the battery fix thoug, hopefully that update comes fast.

Well what is the problem with battery ?? Im having no problem with it. It gived me 15 to 20 hours of battery life in battery saving mode with normal use no games .

I really hope we have a shot with Android L. I just bought this tablet, and seeing the Moto G will get the update suggests that 1GB of RAM should be sufficient to run the new OS.

The problem is I always end up having to charge it after about two to three hours of use, in balanced mode, most of the time just watching Youtube videos. I am almost certain that they advertised much more battery life. The other problem I have is the meter in the notification menu just stops working randomly and I have to restart the tablet to fix it. maybe a defect in my system alone, but annoying nonetheless.

To me its sounding like you have a defective unit mate.

I posted in a few places there is definitely a battery issue I only got about 4 hours playing a game and sending some mails. for a 4100mah it seems less or is it about right? the screen brightness was at 30%, gangstar vegas total play time was about 2hrs 40min and the rest was email on the native email app. balanced mode.

Darn. Its a good thing I still have time to return it. I love the thing but maybe I'll go with a nexus 7 2013 next ttime I buy, just because of stability. I've had a lot of bugs on this one. ?

I keep trying to apply the OTA but it errors out saying there is a problem with Email.apk. Anyone else seen this problem?

Okay, I don't think its a defective unit because I tried using it on power saving mode all day today with music and reading and its still above the 70% mark. I think the bug is that the balanced setting drains a lot of battery.

Glad to hear that helped, I'll try when mine is (hopefully) returned after touch screen issues. I was considering installing juice defender app, which works wonders for extending my phone battery life, but will try power saving mode first.

LRX21Q Improvements

So, I manually flashed the recent OTA. Felt like sharing what I have noticed.
For one thing, EVERYTHING is snappier. Going into recent apps is fast, home screen and apps don't take forever to load. That's a definite improvement. If it changes after running for awhile, I'll update.
Google Now's Always On voice recognition now works. I couldn't get it to work while away from the Google Now launcher before the update.
Uncertain about battery consumption with browsers yet. I'm hopeful, and the back of my tablet not being a toaster oven all the time while browsing on Xda gives me hope, but again, this is me just being hopeful.
Nothing for enabling the notification LED yet. Weird.
All I can see. Share what you've seen here.

Thanks for the impressions. Hopefully the excessive power usage while using browser is fixed or will be soon.
I will note though that even though it shouldn't need to be used to avoid using Chrome, I think that using Tapatalk to browse XDA is a better experience. IMO, of course.

I noticed this too and im glad it wasnt only me. Certain websites cause the tablet to heat up, sometimes taking up as much as 40-50% CPU in the background until i force stop it.

Just flashed and rerooted. I hope its smooth now

That heat is coming from the processor, that just means it's just under heavy load.

Sadly, WiFi 802.1x auth still doesn't work (PEAP) and the "Sign-in to Wifi network" screen is still blank for me. (Tested with Cisco Wireless LAN Controller at work.)

I've noticed the same thing. Basically the stutter and lags have pretty much been fixed. For those wondering the home screen refresh has also been fixed.
I've been testing battery life today in combination with the chrome beta browser. Where I used to get 4/5 hours of sot with a single charge I'm now at 4.15 minutes of sot with 52% of battery left.
The new update has done wonders for the n9 and it just shows how much lollipop is still in it's infancy and still needs some updates to get everything sorted out. I'm sure it's the same for the Nexus 6.

I think he is referring to the re-draw that seems to occur randomly when returning back to the home screen. Based on the impressions I may just flash the factory image to LRX21Q if these improvements are widespread. I still haven't received the OTA and can't sideload it because my tablet is still on the pre-release BL for some reason.

Was never a problem with my nexus 9. Working flawless.

It feels faster for sure, doesn't seem to get as hot either but maybe it does.

Yes I definitely see the improvement. I was one of the first buyers on the first day. But the unit I got has defected NFC chip. I returned it and got a replacement. Latest update definitely fixed the stutters and lags. I can vow for this.

Overheating and Screen Flickering
Do you think that the overheating issue near the camera and the issue where the screen is flickering when the device is not at full brightness, can be fixed by a software update or a firmware update?

François Simond a kernel dev said this.
Francisco Franco9:36 AM+5
Just a heads-up, this OTA provides a VERY significant performance improvement - there was a Kernel regression that they fixed on this build regarding memory cgroups. Its very noticeable while using the tablet with this new patch.

I haven't noticed a difference yet but I didn't do s full wipe when I flashed.

Terrible after 23.0.1.A.5.77 Update

I have just bought Xperia Z3 Compact 6 - 7 days ago.
Battery time was more than perfect.
BUT my phone asked me to install 23.0.1.A.5.77 Update.
After update, battery life is very very bad now.
I did a factory reset, but nothing has changed.
Still the same update. Still terrible battery time.
Thanks

You didn't ask a question so I presume you'd like to revert this update...?
If so, grab FlashTool, install its drivers, and find an FTF of an older update, then flash it. It does not void your warranty and it does not harm your device.

Same problem here, specially when the screen is off.
Something is draining 15% of the juice per night.
- Stamina Mode on
- 3g on
- Whatsapp, Pushbullet and Timely in the "exclusion list"

I had similar issues. Also with tap2wake.
Solution: Reverted back to .98 with flashtool. Now its awesome again.

I had 0% drain overnight last night with this update

If you mean Diagnostics under 'About phone'. I went through all the tests, nothing crashes on mine? Or do do mean elsewhere?

Yes, I meant that, and then the second option "phone characteristic" or something like that, then you see how many times the phone crashed and what processes are involved

Say, how many different threads do we need to have on 23.0.1.A.5.77?

I too am having terriblr battery drain after updating to 23.0.1.A.5.77, I've tried everything; Factory Reset, Flashing back to previous builds. All to no avail.
I've installed Gsam Battery monitor and it tells me that 'Android System' is constantly draining and is at the top of the list.......
I really dont know what to do.

haven't noticed anything different really after the update. the battery life seems the same

I noticed battery drains on my Z3 after the .77 update so I did a clean reflash and after letting it settle in for a few days the battery is back to performing awesomely

I heard such battery issues and still went ahead to see does it really hungers your phone so did the update and I hardly notice any unusual battery drain.
My screen shows 45-61% battery usage and rest all fine. Dont know how to reduce that but its ok.
I get 2 1/2 days battery easily without any stamina mode activated so I guess it pretty awesome. :fingers-crossed::good:

Hi, I did not find a battery drain on my z3c but did find out something on my prev. phone, the z2, my phone went battery hungry after flashing update so I gave it 2 days to settle. The drain kept, driving me nuts. I than did a full wipe didnt help. After formating the sdcard away was the battery drain! Probably some corrupted file or sector on the SD kept the phone draining the batt.
Also seen on other phones that some malfunctioning simcard could disrupt the stability and power usage. Some operators use cheap cards that can just die on there own.
