Nexus 7 Charging Problems - Nexus 7 Q&A, Help & Troubleshooting

Few days ago I used my tablet and got low battery warning I decided to plug it to wall socket so I did it. I heard puff sound two times I unplugged it as soon as possible from what i saw that usb cable was not pushed fully into adapter and adapter burned. Same night i plugged it to original asus charger and left it charger over night it charged perfectly other day i used it without any problem untill it decharged so i plugged it again at evening with 8% remaining charging icon appeared. So i woke up next morning and unplugged tablet but I noticed it had same 8% remaining so i thought we had no power at night plugged it again, charging icon appeared but percentage won't rise it decharged. Than i tryied other cables and adapters nothing seems to help. Searched on google and found suggestions to open back cover and unplug battery for 2 mins I did that. Tryied charging from pc it worked !. So i thought I will move to wall charger for faster charging nope it still don't charge but show charging icon. So i used remaining 15% and flashed android 5.0.2 but it still didin't charge. Installed battery charge info it showing 367mA-500mA with wall and pc charging. So I need your help android users. Do I need new usb cable capable of 2.0A charging and adapter or something other? Sorry for bad english

Battery/Charging Problems

I just recently bought a wall charger since I lost the original one a while back. I've been charging via USB this whole time (maybe 6-8 months now). Anyway, when I charge with the wall charger, it'll say 100% and the green light would turn on (instead of the orange/amber for charging) so I assume that it's done. As soon as I unplug it, it drops maybe like 20-30%.
Is this a problem with the charger? Or the battery itself? I don't think it's battery since I've never had this problem when I would charge via USB. Could it be that my phone's just not used to being charged with a wall charger? Maybe because it's being charged faster with the wall charger that it's "used to" with USB? Any thoughts would be great.
No there's nothing wrong with your phone,if it gets charged via usb,then its fine.Fault is with your new wall charger,is it compatible with your phones specifications ? is it the original recommended or from other third party manufacturer ?. Wall charger must output a charge of 1.0 amp to fully get the pda battery,less then 1.0 amp will not charge the battery. Check this out,ok
Cheers!

[Q] Battery won't charge

Hi! I have a HTC P4350 with a big problem. He don't want to charge the battery. Actually when i plug in the charger he say that it's charging until the green light apears. Let's say that i've plug in the charger at 51%; the phone it's charging until 100% but when i'll disconnect it the battery will decrease again percent by percent and in five minutes or something the level will be again 51%. I have an external charger which it's charging corectly my battery but it's annoying to change the battery to the charger, and when it's full back to the phone over and over again.
So, the battery it's fine, i can connect the phone to the PC and i can sync it so the USB it's fine...
One more thing: the phone was started to do that 2 years ago. I bought that external charger and i used it for 6 months after I've don't use it(the phone) until 2 days ago. So, i've put it in charger and it worked at the first push of the button. I've left it in charger by the night but in the morning i've got an RLOD. So i've use the old external charger and the phone works, only with this problem... he won't charge.
Any ideas? Thanks and sorry for my English

Battery Charge Time

I got my G2 like amonth ago, lost the USB cable that came with phone the first day. Bought long cable off ebay and I am using it with wall charger that came with the phone. The problem is yesterday when I got up (I usually leave my phone charging overnight) it was at 75%. This morning when I got up it was 27% and it was charging all night. Checked battery usage graph and it shows like phone was not charging at all tho there is a sing in notification bar that it is charging. Tried few other chargers from S3 and S4. Doesn't matter what charger I plug in it estimates that battery will be charged to full in 30 HOURS. Can anyone help me how to fix this ?
Thanks

[Q] Is this a known battery issue?

Last night I put my Nexus 10 on charge. I switched if off (it had around 50% battery remaining), plugged it in (via the supplied micro usb cable & adapter), waited for the little noise it makes when you connect it for charging and went to bed. Today I came to use it (it had been left charging for over 9 hours) and the battery was completely dead. Wouldn't even switch until it had been left charging for a minute or so.
Has anyone else heard of an issue like this? If the cable or adapter was faulty I could understand it not charging but I can't understand it losing 50% of it's charge when it's switched off.

Is Turbo Charge works only if charger plugged first and then connect the phone?

Just arrived home from work now with 13% of battery.
I plugged my phone and then plugged the charger to the wall (Original charger).
No "Turbo Charge Connected" toast appeared.
After about five minutes i had 16% and it said i need 2 hours more to be fully charged.
i unplugged the AC from the wall, unplugged the phone, and then plugged again (but this time plugged the charger to the wall first and then the phone) and then i had the toast message and it says 36 minutes left...
I tried it again and got the same result
Is it normal?

Definitely not normal.
Turbo charge work fine if i plug my phone in 1st.
Well....
Maybe it's because i have the US charger and i need to use adapter to fit the electricity here in Israel ?
adapter like this:

*** EDIT ***
It is probably charger's issue. (Maybe because of the adapter)
I tried my Tronsmart charger (5 port charger with Quick Charge) and it works fine even if i plug the phone first...
**** EDIT 2 ****
I replaced this US to EU adapter to new one and now turbo charging is working fine even if i plug the phone first.
Thank you all

I had the problem and solved and answered on my own
I believe its due to weak first connection; whether because of extra shell(cover) or weak connection of USB when attached.
I made a habit of looking for the type of connection from the battery view(AC or USB) after i plug it in.
edit: I have the US charger too...
edit2: the problem disappeared, possible reasons:
maybe USB port or jack got loose and stopped causing the issue
or because I changed the cover I was using....
I have the same problem with multiple chargers. Getting a toast to say "turbocharge connected" happens only after I reconnect it twice. Seems like a bug in my phone.

I edited my previous reply, it may help; observe/do accordingly and report if there's any improvement or not.
There may be another issue due to detection of the phone as a quick charge 2.0 capable device therefore the adapter not charging with full capacity.
Remove extra shell/cover/frame before and plug in firmly at once.
