I have a strange issue when i charge my nexus 7. when i try charging it at night and i wake up the morning after, i see always that my nexus 7 is stuck at 74% charged and not charging more. i have to reboot and reconnect the charger to work. I have kitkat now but the problem existed with 4.3 too.
Nexus 7 Flo... Android 4.4
Mine has same problem, even with screen off it said charging at 71% but even after 1 hour it was the same.
Any solutions for this problem? I am on 4.4.

Well I Recently Bought A Laza ZCell Extended Battery For My Phone And I Ran Through The Calibration But I Noticed That The Battery Life Was Really Bad. I Wiped Phone And Flashed Embryo 6-11 And Charged It To 100. Turned It Off And 8 Hours Later Turned It Back On And It Was At 20%. I Then Decided To Test The Battery Alone So I Charged To 100 And Then Took It Out Of Phone And Waited For 7 Hours And Put It Back In And It Was At 98% So It Cant Be The Battery Going Bad. What Could Be Wrong With The Phone?
Please, get gsam from the play store and post some screen shots.
The main screen, app screen, and click drop down in app screen...and do time held awake.
For starters. Otherwise anyone trying to help is just taking wild guesses.
Also, was it on WiFi or data? Weak signal? That's a battery killer big time on data.
Good luck!

Oh...sorry. Dying with power off?
I'm going to say defective battery....or a phone hardware issue.
Off is off. The phone isn't draining battery when its off...at all. Tho battery will drop in slight steps....cause than just how it works.
But it cannot be software related anyway.

It can be the battery. It could be shorted out. And just by being in the phone (contacts in use) it could be draining itself. Or the phone has an issue similar.

When you say Turned it off do you mean Turned the screen off ..? Or did you power it off .. If you powered it off and the battery drained , then its a bad battery ... Either way I have had problems with extended batteries ... If the battery is the same size as the stock battery and its supposed to be an extended battery then most likely it is just labeled as extended ... The weight of the battery will tell the truth...I have bought batteries that were bigger in size and required a over size cover on the back of the phone and it performed worse than the stock battery.. If the price is too good to be true it probably is .. I AM NOT SAYING THIS TRUE FOR ALL BATTERIES..But it sounds like this is the case with yours ... Hopefully something else caused this and it was a one time thing... If the phone was just sleeping and not powered off then it was draining at 10 percent an hour which is really high.. Mine drains at about 1.5 percent an hour to 2% an hour with wifi on and data on ...If it was powered off and drained like that maybe wipe your battery stats ..You could have been getting a bad reading of the battery which especially if you just flashed a new ROM...Good luck let me know if you fix it and how the battery performs over time I might buy one

Well i charged it and took the battery out to test if the battery itslef is just draining when its out of the phone but it didnt drain when the battery was out of the phone but when i put it in again and left the phone off it started draining by itself. ill get the gsam battery monitor right now and post some screenshots

If your phone is powered off, screen shots done have anything because obviously they aren't running.
Or are you talking standby when you say "off"? Like screen off. Not completely powered off.

i mean completely powered off. the battery has gotten a bit better after some charge cycles. but its still dying pretty quickly regardless if its on or completely off. this is all while on airplane mode and having only wifi on
Also is there a way to check what the mAh of the battery is within the phone like an app ? .
If the phone is off, no app or widget will help, or tell you anything....cause the phone is off....so the app is off.

i know i just want to check if the extended battery is the intended mAh
I'm using original charger and I'm forced to shut down when ever I plug in charger. I tried other usbs and same thing happens, I can't use it while charging?
Also I charged it overy night to 100% turned it on about 30 mind later and it was at 92%....what's going on?
Thanks guys!
Mine does the same this tablet takes a lot to charge you can't use it when charging or it will shut down

That's lame also I had it on for 3 hours and playing castle clash and I'm already at 35% do games drain that much battery? When I had nexus 7 2013 it lasted for ever....:crying:
Yes, @one hour of the room two about 25% battery drain, blame the screen so nice but so hungry

BTW I can use with the charger but seems it doest charge at all

I think I'll exchange it if it's still doing the same thing I'll just get the nexus 7 again or the pro:--( but I like how thin this is
Edit:
I exchanged it, it seems to charge fine now while using it. It was a defective battery.
Hello,
Since I've updated to 4.4.3 a few months ago I noticed my battery is draining faster when I'm not using it (i'm on wifi at work). The problem is at HTC Service Pack, and sometimes at google play services (I've read on this forums that 1h of keep awake per 24h is fine, I don't always get this, sometimes it gets to 2-3 hours).
Before I would usually get 1% drain per 2-3-4 hours, now i'm getting it at around 1-2 hours.
Here are some screenshots, what do you think ? Can I do something about it ? The last 3 keep awake bars from the screenshot it was when I didn't even touch my phone, and as you can see this is done on some schedule (20-30 mins every hour). This thing happens to me all the time, but only after I fully charge my phone and then going for work, I don't remember seeing this behavior when I'm home.

My phone's not rooted so I can't give you more detailed data.
That's still at best 0.5% per hour. That's pretty good still.
It's probably a little worse based on apps you've installed running in the background. I certainly wouldn't be concerned at this point. ?

You do have some held awake time there, but without root.... It's anyone's guess what it is.
I've noticed a weird pattern in recharging.I usually recharge it while it's off.
Yesterday after 3 hours I turned it on and was at 50%, then it remained at 60% for one hours or so, I restarted it and it reached 100% normally.
Today it took 90 minutes to reach 16% but after I turned it on it quickly reached 33% now, after 10-15 minutes it's at 37%.
I haven't tried a different power outlet yet. My model is the ze500cl
i haven't timed it but its a lot faster than my one plus one at charging

Charging slows down as the battery approaches max capacity to prevent overcharging and to maintain the health and safety, as well as capacity of the battery.
Switched charger recently. Stock cable. This good?
Am running Aex 5.1

It's not bad but it could be even better (like 2100 amperes with the same temperature)
Use a 2/2.4 ampere charger and you will get your device fully charged in 90 minutes with 27-29 ºC.

I have checked the percentage of your battery and you have the correct amperage. Because the amperage decreases as you charge your phone. For example, if you start charging your Zuk at 20% of battery, the charger will give to the phone a lot of amperes, it gives the full power; but when you are at 90%, the amperage is much less, because it gives smaller current impuses.
