Hi, I bought N7 (2012) 16 GB in December 2013 and suddenly it's charging went slow. At times, it just charges 5% after plugging in for 5-6 hours. I've no idea what's happening with it. Any clue?
Same here.
E.g. last night I turned it off at appr. 30%, plugged in the charger and in den morning it was at about 50%.
I am on PACman Rom 22.1.0
there has many issues about fast battery drain after kitkat especially about N7. There is no definite fix for this but you can try not to let it decharge under %30-35 because the lower battery is the longer it charges.. good luck with pluging and unpluging the charger a few times in out in out , it helps they said.

No, my case is something else. Everything was working fine and this problem happened suddenly one day. At times, while charger is plugged in, if I play game, battery starts to drain even when it's charging. There has to be some problem with the battery but I ask why did this happen and that too suddenly.
Get gsam from play store and see what's eating your battery. Or post screens here.
If you're rooted, you need gsam root companion as well. Shows more details then.
Otherwise we're all just guessing.
Mine started doing that just yesterday. I updated twrp today and did a wipe of everything, went to reboot, now it will not turn on at all. Won't even charge. I got it to turn on finally but it won't go back into recovery. Just gets stuck on the part when you first turn it on.

Here's something crazy! I unplugged the battery for a few hours, plugged in the power cable, tried turning it on (didn't work for obvious reasons lol), then plugged the battery pack in. Now it's charging fine and was able to boot into recovery.

Okay so i've updated to Cyanogen 5.0 beta 2 no problems installed 2.6.32 then went back down to 2.6.29.6 and extra ram works and everything but now my phone wont charge the battery.
I'm quite sad as this is the problem, someone mentioned to let the charge die and then try charging it then. So i did that and now its stuck at 0 and when i remove the charger it instantly dies. Only one other member had the same problem but he hasn't replied to my pm or the thread yet so i'll wait for him as he had this abit earlier.
I've done multiple wipes, reinistalls, nandbackups and now i'm too afraid to do anymore flashing as the phone's battery is on 0%. If at any point it requires phone battery to flash it will die and i'll have a brick.
Hopefully someone out there might have a solution
I dont think its a ROM problem since you wiped. Perhaps its a hardware problem?
i dont know. Does anyone know if its safe to flash? As in if the charger is in it should be okay right?
Okay i think i'm screwed for awhile. The battery is drop dead and now i cant enter bootloader mode. Theres a orange led at top indicating its still working but wont enter bootloader due to insufficient power. Damn i was going to try to flash it
Now i need someone with either a nexus one or another battery

Have you tried another charger or the USB cable?
Same problem here
I'm experiencing the same problem myself.
Installed Cyanogenmod 5.0b2, everything worked fine for the day.
tried JIT, had reboots, reverted back to fast
Upgraded to .32 kernel, my sdcard wasn't compatible so re flashed 5.0b2
called it an evening, my battery was full but I plug it into the charger overnight since it's my alarm clock.
Yesterday morning on the way to work, was playing music and noticed my battery had jumped from full down to around 12% in 30minutes. plugged it into car charger, and while it didn't drop anymore it didn't charge either.
Left it in pc usb charger off and on all day where the off times it dropped down to around 9% and never got above it. Eventually let it die on the way home thinking I'll re train the battery.
Left it off and plugged into wall charger for 4 hours, but batter stays at 0%
I'm glad I didn't sell my Dev G1 yet, as at least I have a working phone for the moment.
FYI I ran into this same problem running superboot himem on ERE27. My battery died and then nothing would charge it, even sitting it on AC power for 8 hours (while I slept) when I woke up my battery was stuck at 0% and would auto shutdown if I unplugged it.
I nandroid restored to stock ERE27 and immediately my battery started again. I think there might be some weird problem with himem mods. Not sure. Just to be safe I am totally over flashing custom stuff on my phone. My phone is too important to me to risk stuff like this happening.
My phone just went dead yesterday, while playing tiny tower. Suddenly turned off, and would not turn back on. When I connect the charger, the led in in the speaker blinks. When the charger is not connected, the phone is completely dead. And it does not respond to anything either way. I don't know if this is rom related. Probably not? I'm thinking returning it to the shop, and hoping for the best is my only option, unless someone here has a better idea.
Update: I tried turning it on, connected to the charger, but without the battery in. It starts. So I guess the battery died? Suddenly and completely?
What happens if you turn it on without battery in and then insert battery?
Mine did a similar odd thing when I first wiped battery stats. Was playing angry birds to drain battery right down and it turned off, but would not start. LED just blinked when power was in. I just had to plug it in and unplug it a bunch of times and it finally started charging.
I did wipe battery stats last week, but have been through a few drain/recharge cycles since then. When I start with the charger connected and insert battery it gets past the boot animation and then shuts off. I tried with a different battery yesterday, and it worked fine. When you say plug it in and unplug, do you mean connecting and disconnecting charger, just repeatedly?
yeah, was just plugging and unplugging a lot and it finally worked. If another battery worked then that would seem to be the fix.
Will try that. Thanks!
Managed to get it to start by putting the battery in after starting with just the charger first. Had to try a bunch of times before it worked. Been charging now for 5 hours, but it never gets past 10% charge on the battery? Do I just let it keep charging or is there some other way to fix it?
That happened to me in the day I bought my phone. It only started with the charger plugged in (and with no battery).
I thought the problem was in the battery, but in the store they tried with a new battery and the phone did not connect. So they replaced and everything is fine (since September).
Basic Info: I'm currently running **[4.2.2][CM10.1][LINARO]Team Asylum CM10.1 Nighty, build date April 18 (Had recently flashed lastest nightly, then started noticing my charging issue, and flashed an earlier version to see if that would fix it.. it didn't).
The problem: I let my phone on my wireless Energizer Qi charger overnight. Charging indicator lights all went on, and I went to bed. I woke up the next morning and noticed that the phone was only at 37%. Putting the phone on the wireless charger, i noticed it will light up, then turn off, then light up, then turn off. Figured, something wrong with the charger/case, so I removed the case and tried again, same thing. Tried attaching to computer via USB, and the same thing happened, the connection dropped in and out. Now I have it attached to wall outlet, and the same thing is happening, especially if I move it around.
I managed to get it to a consistent charge (says USB though its plugged into wall..) by leaning the phone up against something, but if I move it it cuts out...
I first was thinking maybe there's something wrong with the microusb port, like what happened with my HTC Evo after a while.. but the same thing happens with the wireless charging.. So, I'm not sure what to do.. Whether it's a rom issue, a hardware issue, a kernal issue.. Any thoughts on what I should do? Wipe battery stats?.. RMA?.. Complete nandroid restore?
Adding: I have Snapdragon Battery Guru on there.. if that's relevant to anything.. https://play.google.com/store/apps/details?id=com.xiam.snapdragon.app&hl=en

UPDATE. Flashed francos milestone 2, and the problem seems to have disappeared.
UPDATE 2: jk it's still doing it.
I've had the same issue for about a month now. I removed the snapdragon battery guru app and it doesn't do it as often now but it will still do it. I also calibrated my battery with a battery calibration app when it became fully charged and now it will only do it about once every three days. I don't really have any other advice than that, all I know is that my phone started doing it after I finally caved and flashed a kernel.

I have the same issue and I'm completely stock and unrooted. I will wake up in the morning and the battery is at, say, 80%. Unplugging the a/c and plugging it back in doesn't help at all. I have battery widget reborn and it tells me my battery is charging at 1% per 30 minutes. This morning I hooked it up to my HTC 8X charger and it immediately started charging correctly so I'm inclined to believe it may be the charger but it could've been coincidence since other times unplugging and replugging it works. Some other times I have to power off and then on in order for it to work again.
Hello people!
I've had my Nexus 7 for about 4 months now, and it started having battery problems a couple of weeks ago.
After the battery had drained completely, it wouldn't charge at all. I followed some steps to solve this problem, and managed to get it up again, but after that, charging it has been a nightmare.
To sum up:
When my tablet is on and plugged in, it shows that it's charging, but the battery slowly drains even if I don't use it for hours. If the tablet is off and plugged in it shows that it's charging, but it is not.
After it's completely drained, I have to go through the whole recovery mode, turn off, thirty second button push process to revive the tablet (which otherwise does not work at all) and let it charge while off. After that the tablet works fine, but does not charge.
I even did a factory reset, but nothing happened. Also I'm using the charger that came with the tablet.
Should I ask for a new one with my Guarantee or is there a fix for my problem?
maybe its some internal issue, if it came with a warranty. maybe go to the place where you bought it and see if they will replace it with a working N 7.
So here's my story.
I was using my tablet like normal, and the battery level was around 90%, when suddenly the battery level drops to 0% and my tablet dies. I always charge it every night, and I've never had any issues before, so I figured it couldn't be a battery issue, and I've NEVER had a battery just suddenly die on me before.
When it's plugged in, it shows the battery at 0% and charging, but it never goes above 0%. It works just fine plugged in, but as soon as I unplug it, it says Connect Charger, Power Off... Shutting Down.
But here's the weird thing! I know it can't be the battery, because when I start it up in the bootloader and it's not plugged in, it's absolutely fine! It can run hours at a time without being plugged in at the bootloader screen. But as soon as I start up the system, it gets to the X loading screen, then shuts down.
I tried flashing back to stock everything. Stock 4.2.2, stock 4.3. Nothing works.
Any ideas before I send it back to Google for repairs? :crying:

Did you do full wipe when you flash back to stock ROM?
I believe I have experienced once similar to yours. Not sure how I did it but I think it is "rest for awhile" (5 min), e.g. charge with power off, unplug USB cable, wait a few minutes and turn it on.

I downloaded the stock images from the Google site and ran the .bat file.

Yes, everything was wiped out. I let it charge overnight and now it's stuck at 7%.
Anyways, I'm sending it back to Google.

Which recovery are you using?
