[Q] Odd charging issue. Not typical Nexus 7 batt. issue. - Nexus 7 Q&A, Help & Troubleshooting

So I've had my Nexus 7 and have been quite satisfied with it but just my luck, with just over a year of ownership and outside the warranty, it starts acting up.
Basically, my Nexus 7 will no longer charge to 100%. I can already hear the feverish tapping on the keyboard that this issue has been addressed but it hasn't. It's different than the other threads that have popped up, which I've read through and tried the various suggestions. Here's what I've tried to do, none of which work:
- Swapped the USB cord with my Galaxy S4.
- Swapped the charger with my Galaxy S4.
- Borrowed my GF's Nexus 7 and plugged in her battery into my Nexus 7.
- Tried a different electrical outlet.
- Factory reset and battery pull for ~5 minutes.
- Updated to 4.3 (This started just before the update was pushed OTA).
Here's the kicker. It does seem to charge if I plug it into the powered USB ports on my monitor. HOWEVER, it only charges up to about 57%. After which it kind of just hovers there. It'll charge a little more sometimes, or sometimes it'll drain a bit but the average charge is around 57%.
Thoughts? It seems to be a hardware issue since it won't charge my GF's battery either or charge from AC, even though it detects it.

[Q] Battery not charging?

I got my Nexus 7 yesterday (bought from Google Play), I played with it, installed apps, etc.... at about 11pm I plug it in to my factory charger which is on a surge protector, it proceeds to charge while I continue using it for 2 hour or so. When I went to bed I turned it off. I noticed the charging indicator (battery filling up). When I got home today I unlugged it and tried to turn it on...Nothing, so I plugged it into my computer, the charging indicator came up, I waited 5 minutes and turned it on, I then went to the store and when I got back I went to plug it straight to the wall for a faster charge, when I moved it it immediately powered off. After 5 min of "charging" I powered on and went to the battery summary page, it says 0% charging (AC). Its been here for about 30 min now, the usage graph shows a flat red line. Is my battery defective?
Nevermind. False alarm, thank God.:victory: My usb extension cable seems to be the problem. Also if anyone is curious, the htc usb cable works fine and is longer.
My Nexus 7 won't charge. I've tried 3 chargers, including the provided one, all of which work on several phones, but none work on the Nexus 7. And it's been a tedious few hours in a queue on the phone trying to get hold of anything to even start the returns process. I can only assume the stories you see when you google 'nexus 7 fault' are true and that many, many people are queueing up to get their faulty unit refunded or replaced. It's a shame - I've played with a working one and it's very nice.
I've had a similar problem for a few days now. When its plugged in, on or off, it will only gain afew percent battery even over a full24 hours. I broke the tip of my stock cable, so thats not an option but ive tried with several other cables with the same results. I'm afraid to use this thing any more unless its plugged in so since it may not charge once it dies. Did you ever solve your problem?

[Q] Nexus 7 Charging Issues

Hello;
So far I am really enjoying the Nexus 7, except for charging issues. I can only charge it via usb from my Chromebook, when I plug it into the Asus charger or my Nexus S charger, nothing happens; my Nexus S will charge using either charger. I have tried doing a factory reset several times and the problem still exists. Also, I haven'f flashed it and currently I only have Google Apps loaded on it, the latest official Android update (4.1.2) has been done.
Suggestions?
Thanks
Sheldon
If I use the charger and cable that came with the N7, everything works as it should. I tried an alternate charger/cable one time and It didn't show it was charging and didn't show the charge % increasing. But I left it plugged in a couple of hours and when I unplugged it, it updated the battery % and it had gained charge. I think it can be a reporting issue as opposed to a failure to charge. There is something different about the N7 charger or cable that makes other charger/cable combinations report differently.

Said goodbye @ UPS to 8013 Will Not Charge

I just said goodbye to my 8013 Note 10.1 at the UPS store. Going to Samsung for warranty service. Will not charge when plugged in to charger or plugged into USB on computer. Tried 2 chargers, 3 cords, and 2 computers.
Have had the tablet for 6 weeks and I love it. Day after Christmas I noticed the battery was only 22% after being plugged in overnight while turned off. Searched the forums, but did not find anything close. Only suggestion Samsung had was to do a factory reset. Since I figured it was going to have to go back for hardware fixing, I used a lot of the remaining 22% battery to ensure I copied everything I wanted to the removable memory card. Factory reset had not effect.
Anyone else have this problem? The connector looks a little flimsy to plug/unplug hundreds of times a year.
The tablet just doesn't charge from the computer no matter what. The very low power the USB provides only suffices to keep the tablet from discharging.

What he said. You cannot charge from USB (maybe USB 3.0) or your usual phone chargers.
I should have been clearer. The computer and tablet show no sign of connection. I realize charging via USB is iffy, but I have seen my battery percentage grow while connected to a USB (2) port.
I meant to mention this failure of course happened while I am out of town without even a paperback book to read as backup. I should have trown the old Kindle in the car before we left, but never expected the tablet to fail at 6 weeks. In the first week maybe.
U Can charge it from the computer it has to be turned off and the only charger that will charge the tablet is the one that came with it

[Q] Charging Nexus 10...

I`m represantate 4pda thread of Nexus 10. Lots of people experience troubles with charging our Nexus (including me).
Using native charger in turned off tablet it gave only 50% in 8 hours (in my way)
Others say approximately the same.
I have root, unlocked boot, use Gravity Box (xposed). (It would be normal if my case were sporadic, but...)
Do you know any solve of situation?
I am also experiencing this lately. I'm not sure if it's from the kitkat update or not, but same story here, I leave my tablet charge overnight and when I get up it's at 75% after at least 7 hours of charge. I tried stock kernel, thunderkat and ktmanta, didn't solve the problem.
I've ordered and waiting for N10. I was going to immediately unlock, flash stock 4.4 then root and apply Kernel
I've also ordered a Pogo cable as owners seem to get a faster charge, also to reduce wear on the microusb. I assumed I would be using the supplied microusb PSU?
I've had a N7 for 17 months and on it if I was using it, even with 2Amp PSU, it would often just hold its charge, so not gain charge, when used, I'd have to leave it screen-off to charge. So with N10, you've got experience even when OFF (powered off, not just screen blank) it isn't charging? That sounds weird. If however, it is simply screen off, then go to your battery and see which app is keeping your power consumption up and do something about that app surely???
I noticed it immediately with the micro USB cable and stock charger I have been using since I got mine (just after release). Usually 1100-1700 mA charging. I noticed the minute I updated to 4.4 that my charging averaged 600-800 mA on the USB. After an 8 hour charge it was like 46 percent. It really scared me, thought my tablet was going. I tried switching cables/chargers. Stayed the same.
I switched to the stock wall wart and the pogo plug and it jumped right back to 1700-1800mA till 80 percent charge and then starts dropping. Something it had never done with the pogo. I had to search drawers to find the pogo since I had given up on it's poor performance. It has always been about or less than 1000mA, which is why I always used the usb charger. It seems to be much faster charging now, but only with the pogo. USB barely seems to provide enough power to maintain the charge!
That was the first day on 4.4 manual update, haven't checked since that minor update to krt16s to see if it changed. The pogo seems to be quicker than any charging was.
Yeah my problem also appeared arround the kitkat update.

Finicky charging?

So we've been combatting some finicky charging issues with my wife's new S5 for the past week.
I've worked out a lot of the weirdness due to the fact that my HTC M8's charging brick apparently doesn't work with anything other than the M8 (I have no idea yet what is different about it... 1.5A).
Anyway, despite this we have had no issues using the supplied charger/cable (only used it on first day).
We haven't had any issues using an old Droid 2 charger and cable (1.0 A I think)...although likely it was a slow charge.
But, since we've been out of town for a few days without all our cables, the only think that has worked with NO issue is using a 2.1A output power brick to recharge the phone. Also, it seems that the 2.1A iPad charger worked as well.
What is weird is we also tried 2 identical 1A iPhone charges. Upon first plugin with a 10' 24/28AWG cable, it didn't charge. I removed it and plugged it into the other one and it began charging. I then removed it and plugged it back in the first and it started to charge fine (and yes, I tripled check the connection on the first try).
In short, we seem to just have very strange results. Sometimes it will say it is charging for a few seconds and then stop and sometimes it will not charge using a certain combination, but when you unplug it, try something else, then back to the first it will work!
We've also had issues with the charger in the car where it would keep blinking her phone on and off with a sound. I suspect that this was due to a slow charge bringing the phone to full charge, then dropping (even though plugged in), then going back to full again. But this is just based on what my wife described.
Can anyone explain and/or tell me what the minimum required and the recommended specifications are for a charger/cable on this phone?
