New Nexus 10 - out the box battery issues - BOO!

So I took the plunge after growing tired of waiting for the Nexus 2.
There's no doubt this is a super slick Android experience (I've come from a modded Advent Vega)
Gorgeous screen (although I have bottom right hand corner light bleed, but not too bad) and pretty swift.
The battery problem started right away and I'm wondering if any one else has experienced this.
I started the updates to 4.4.2 right away, this took about 10 minutes and the battery drained from 100 - 80%.
The battery dropped 3-4% every 10 minutes - in effect a 5 hr battery life.
When it got down to 50%, BAM! It instantly dropped to ZERO.
Seriously underwhelmed....

Hi,
How is battery life after it shut down and you recharging? Maybe it was a post installation bad battery life... Also be sure to have the screen brightness low. Some other user had the same 50% issue, I don't remember what he did to fix or if he fixed, you may want to be interested into reading his thread,
Please, check the battery life after you charge it and if it's still THAT bad, I'd recommend calling a Service Center.

Thanks for the reply, much appreciated.
OK I take back what I said about being underwhelmed. Battery life could be better but the experience is superslick. Coming from a Vega, holy moly...
I recently bought an iPhone and regretting it. Apple have a lot of catching up to do. Google are nailing it, from the OS to the ecosystem, and the nexus is a dream to use.
So I recharged to full
Screen set to auto and around 40%
Blue tooth off
Screen hasn't slept at all
Activities:
3 hrs Downloading apps and surfing
1 hr video streaming
1.5 hrs video playback (non HD)
10 mins of need for speed
Result:
6 hrs with 5% remaining = 6 hrs 15m
Not terrible, but not great given the charging time. Having read a lot about the battery life I saw 7hrs video playback with screen on full so I'm a bit dissapointed. The bleed is minor and I can live with it.
Opinions and experiences welcomed, does this feel right?

Hi,
Glad my answer could make you see a little more further . My experience is with it running in an even lower screen brightness, screen sleeping some times and also playing some heavy games or surfing the web. Aldo I have Fedora 19 running background.
That gives me 8-9h of battery life, also temperature here is more or less 28-30°C . Temperature influences a lot battery .

One more thing - ”currents” app is working in background all the time. Disable auto sync and battery life should improve a bit.

Do a stock flash 4.4.2 it fixes issues which arise when you do a 4.2.2 to 4.4.2 OTA upgrade. I never knew the reason why and it might be just do a reset to factory within settings might be just as good, but I just did a flash stock. My suspicion is this relates to formatting the filesystem with newer software may make it faster for I/O, because I found file-copying faster and less CPU in 4.4.2.

Is this issue got fixed after full recharge? I got the same issue for the out of box piece.
For 10 mins of browsing it is consuming 3% of the battery. Is this normal?
I left my tablet in sleeping mode and came to work. Need to see what happens once I back home.

My nexus 10, darined all of a sudden from 56% to 0. Is that OK. Do I need to ask for a replacement?
Thanks in advance.

My N10 which is 13 months old had this issue last night.
Used it for a while after it was fully charged. Turned it off at 90% but it was completely dead today, had to charge it for a while to get it to start.
Anyone send one of these back bought from Google Playstore in the UK?

[Q] Battery life seriously sucks... HELP!!

Hey guys
Need some help here
So my nexus 7 2012 wifi, bought in Australia in December of 2012 has gone haywire and I don't have a clue why
My battery life... Which was awesome till some time ago now socks!
My battery which was 51 % when I started watching an h264 encore movie was around 5% by the end of it... And the movie was exactly 3 hrs long
I don't now what the problem is
My battery has depleted by 10 % in the last one hour
Lemme give you a list of the apps which may be causing the problem
1.whatsapp
2.viber
3.tango
4.skype
5.xposed framework with
5.1.youtube adaway
5.2.greenify
5.3.Keepchat
5.4.gravity box
5.5.swiftkey goodness on more fields
My nexus is stock rooted with stock kerne and running the KOT49H android version
I use SwiftKey by the way.. Just in case
This has been happening since the last one month around I think after I installed xposed but even then there must be thousands of nexus 7s running xposed and mine is causing problems
I'm a moderate user and use it mostly for browsing and listening to music
I just installed whatsapp. But already had tango viber and Skype before all this.
What do you guys thinks... Is it because of the aged battery or some other software component. I have tried factory reset and the battery test using the movie as a reference was conducted without installing xposed after I had factory reset my data but whatsapp had already been installed by that time.
Please help guys... I love this thing and I don't wanna lose it to battery troubles!!!

Update guys...
At 8.23 pm my battery was exactly 50%
By 8.43 pm it went down to 45%
Thats a decrease of 5% in 20 mins
And this is with light whatsapp usage and browsing and that too for not more than 10 mins
Other than that the tablet was asleep with wife switched off
And also forgot to tell you guys the wifi is troubling me a bit too. But I suspect that may be due to connection problems due to the distance between the two devi es and also it does take a little time to connect to the internet even after the signal is shown as fully connected. This started today.
I'm freaking out. Help XDA crowd!

Get gsam. From play store. And be sure to open it once. Charge to 100 and let it go til you're pretty low.
Then see what its saying. It usually can help find most battery issues. Post screen shots from gsam here if you want help.
Good luck!

[Q] Nexus 4 sudden signal loss, battery drain and shutdown!

Hi all,
First post so go easy :angel:
I've had my N4 for about 18 months. Ever since 4.4.3 (now on 4.4.4 and nothings changed) I think I have been having some probelms.....I also dropped my phone around the time of the update so can't rule out a hardware problem, anyway....
On full charge the phone is, after a random amount of use perhaps around half battery, it drops signal completely....then it start goiing crazy, opening apps clicking on things (sometimes locks up) then shuts it's self off.
Once I turn it back on it says the battery is almost out.....even though before the crash it was at 50%???? (Please see imnage below for "cliff edge" on battery screen shot!)
I have tried safe mode, I have done a factory reset and removed all and any apps except facebook. Other symptoms include forgeting wifi and other account logins!
Also worth noteing I dropped it and smashed the screen, I then had it repaired and voided the warrenty (?) because I needed it same day for work.....dont know if thats connected was working fine for a while after this happened.
I have seen various posts of this forum and other about this kind of thing but no exact answers.....any help would be great 7 months until free new phone
Sudden drop is extreme right....

Re flash factory images for a full wipe, if it doesn't work after that then its probably hardware (sadly), maybe you could get a moto g? I've heard there really good and cheap.

Sounds like something went wrong during the repair or drop and that this is a hardware issue. As suggested, try flashing full stock, but I am pretty sure this is a hardware problem, unfortunately.

Thanks guys .....Ive been doing as much reading as pos.
Some people are saying reather than the drop its maybe just a failed battery? thoughts?

It could definitely be a possibility. If you are up to it, you could purchase a new battery and try to replace it, there is just the risk of damaging something further.
Sent from my Nexus 4 using XDA Free mobile app

Same things happen to me. I thouhgt the battery is comming to end and orderd new one but I have read that people have some similar problems after updating from 4.4.2
On nexus 5 people also have problem with to fast battery drain. I have similar problems. I lose network, afterwards battery drop from 20-40% -> 0%

Same thing is happening to my wifes NEXUS 4. Hers is a little over a year old now. It was dropped and I replaced the screen a few months ago, but ever since the new updates, her phone has been going CRAZY!
The phone randomly loses signal, battery drains quickly and apps open close (ghost touches) and then it shuts down.
I've cleared the cache, reset to factory defaults and even run in safe mode and nothing. The phone is useless now, she maybe gets 2 hours of normal use out of it before it goes completely nuts again.

One of us should roll back to 4.2.2. and report the result

Facing similar issues. Have posted it here. http://forum.xda-developers.com/nexus-4/help/fast-battery-discharge-t2799931/post53790262?nocache=1
Any solutions?

I am waiting for a new battery. Try rollback to 4.2.2.

ITs same on my phone after an 4.4.3 update teh N4 gone rogue before the update it was working just fine I just did factory reset got back to 4.2.1 android and its doing the same

Just to keep you up to speed...I suspect it may be the battery....or perhaps power management issue/conflict??
Trick is if I keep my battery charge above 60-65% it's fine......get below that and the trouble start.....weird. hvaing said that seems to drain faster than normal also. My hope are pinned on battery solution once Rajnus trys it.
Although not looking foward to taking phone apart to replace it

Today after the first symptom I rebooted phone and after reboot my battery was at 14%. It looks like to me that we have constant drain but system some how is not registering it properly. I will restart after every 10%
Edit: 85% ->reboot -> 57%

I'm glad to see I'm not the only one suffering from this issues as well. I replaced my screen and digitizer about 3 months ago and never had issues. Last week I updated from 4.4.2 to 4.4.3 (and 4.4.4 shortly after) and started having the same issues where there would be ghost touches on the screen once I got to around 70% battery, loss of radio/signal, and when I would restart the phone, I would lose majority of the battery charge. I tried flashing stock back on the phone and the problem still is present.

Just to repeat that is exactly what is happening to me word for word.

Random power-offs

Not sure if this is for the QnA section...anyway, yesterday I got a Nexus 7 2012 16GB for my Nexus device collection (used). It was rooted when I got it, with a whole bunch of junk of it, so I used Nexus Root Toolkit and restored it to stock 5.1 (from rooted stock 5.0.2).
Last night however, I noticed two things that seem weird:
- the battery charges really slow compared to my other devices (5 hours for full recharge) and drains quite fast when playing games (compared to the 2013 N7), namely Zombie Driver THD
- self-power off during night charge
While the first one seems normal (it IS used after all so not expecting perfect battery life here), the second one makes me worry a bit. I'm at work so not sure if the issue will repeat, but the battery was certainly not dead when I plugged it to recharge but the tablet was switched off in the morning. Using the original N7 2012 charger by the way.
Any chance this can be ROM-related or is there any known problems like this?
I have had a 2012 N7 in the past but in Android 4.4.4 I didn't have the self power-off problem, maybe a 5.X bug?

Takes me 4 hours at max to charge it from 0 to 100
How much does it last on gaming? I can play heavy games for 1.5 to 2 hours, thats about it. No kernel/rom has given me more than that. It's tegra 3, don't expect much from it.
Some users have reported that bug on 5.1 I however did not encounter it. Although I used 5.1 for just about a day and came back to 5.0.x for xposed

I just came back from work (roughly 13 hours away), the battery seems to be at 97% (no WiFi on) and the tablet was not turned off.
Guess I'll monitor it for a while longer, though knowing how much I plan to use it, it might take a couple of days before I drain it enough to warrant a recharge so that I can test to see if the charging turns it off.

So I thought the issue fixed itself, but last night I found out more about it.
So I haven't used it for about a week or so, it was fully turned off with a charged battery. When I tried to turn it on, it wouldn't work even after multiple tries. So I thought maybe the battery is screwed, so I plugged it in the wall, but no battery charge indicator showed up. I waited a couple of minutes and tried to turn it on but it didn't work, so I left it there "charging". About an hour later I tried it again and it worked, battery was at 100%, so I left it on overnight and it hasn't powered off on it's own.
Anyone can advise on this? I'd just go ahead and re-sell this one, but it's in great condition so I'd prefer to keep it if it's fixable.

I've had a few random power offs or maybe lockups on 5.1? Not sure entirely if it was powered off or locked up, I'm running Complete stock unrooted

Complete stock here as well.
I decided to downgrade it to 4.4.4, we'll see if that fixes it (I'll report back when I believe I tested it enough unless someone gives a known solution or suggestion).

I think you should try installing a new battery if KitKat doesn't fix it.

Dying quickly and taking forever to charge even after replacing the battery...

I'm experiencing an extremely frustrating problem with my N7. I noticed I get very little usage time out of it (1.5-2.5 hours watching youtube videos, playing games and TV shows) and it takes forever to charge (8+ hours from 10% to 100%) so I figured the battery is on it's way out. I've had it for almost 3 years so that would make sense. However, I bought a new battery (this one) but it hasn't made any difference. I lost the original charging cable so I suppose the slow charging could be at least partly due to that, but I remember for the first two years I had this thing, I could get at least 4 hours of continuous use out of it, usually 5+. I used to be able to leave it off the charger all day while I'm at work and the battery would hardly go below 90% but now I leave it off the charger for 6 hours and it's down to 45% from just sitting there idle. I have Greenify installed and have it set to hibernate all apps except Apex Launcher.
Has anyone else had this problem? What can I do to fix it? It has an older version of CM 10 on it so I'll try to flash a newer stable version. Should I try a new kernel too? I don't think I've ever done a firmware update on it either.
I would really appreciate any help. I'm ready to just smash this goddamn thing with a hammer.

Anyone? :/

It happened to me before with slow charging then I ve replace with my lg g2 cable then it work normal again.
For the ROM I am using cm12 it works good on my nexus but that's my opinions. You can try other ROM which suits you.
Thanks I hope this help.
