My friend gave me a black berry charger which has always worked for me in stock, cm 7.0, 7.03 but sometimes I have issues with 7.1
I either charge my nook via the official adaptor, a usb cable on my computer or via this bb adaptor at work that has always worked in the past.
But a few times I've left in charging all day at work and then it's in SOD mode. Usually I hold down the button and reboot the nook and it's fine. However the last time it completely drained my battery (even though it was plugged in all day at work) and couldn't get it working again until I charged it with the official charger.
Usually the official charger takes roughly 3 hours for a full charge, trickle charge via usb or this cable takes about 8 hrs. But I've left it plugged in at work and sometimes even after all day it's only 50 % charged and will never seem to reach full charge until I charge it at home with the official charger.
Again, never had the issues prior to 7.1. I've read about the SOD and always considered myself lucky that I never had any SOD issues, but now it seems 7.1 and this charger causes issues, but only sometimes.
Anyone else encounter that?
oh yeah. with my nook charger, though. until I added the patch, I had to turn the screen off before I plugged in the AC adapter, or else it would just turn off. the patch helped immensely, and I also had no issues when I was running the mirage kang. if antone can find/ make a Pdroid patch for the Mirage ROM, I would be set.
I've had a couple of spontaneous battery drains - once when plugged in. They only happened when I was using a live wallpaper so I always chalked it up to that. I've yet to apply any SOD patch, although I am running the latest nightly 253, so if they rolled anything into that I have it.

ive had it for a month and a half and now its doing this, plug in the charger to the tablet and nothing. ive tried with different outlets aswell ive checked my power adapter to see if its one of the effected ones but mine was a pre assembled one. ive also restarted the tablet with no luck. time to call asus?
Do you have another device that charges by usb, that you could plug in to see if it sees anything for power? Not sure on the usb pinout for our chargers, but if someone knows, you could use a voltmeter to probe it and see if it has any output.
k got it charging now, hooked it up to my pc with the usb cord to see if the cord or the socket is shot, still connected to my pc....but it reinstalled device drivers as if i never used it on my pc. i turned usb debugging on then off, then i unplugged it and put the cable back into the power adapter and its charging
this is concerning, seems like a usb driver issue that effects the port not sure if i should call asus and do something about it
Sorry to bring this up but I started noticing this today too. I've had mine for about a month and everything's been fine. I noticed that the battery was in the 30s so I plugged it in via the a/c adapter and neither my battery widget nor the system battery icon change to the "charging state". I shut the device off to see if it would charge quicker and left it off for what must have been an hour and the battery has only increased by about 7%. I'm timing it now to see how long it takes.
This happened to me this morning. I couldn't get the tablet or the dock to charge. The dock was at 3% and the tablet at around 75%. Neither would charge either singly or together. I tried using a normal 5v USB charger for a few minutes, but without success. Then I fiddled with the charger and uncoupled the 3 pin UK adaptor. It then started charging. I'm not sure if it was coincidence or not, but at the moment it's working.
B50K tablet and B50K dock.
I have a B50 also running the newest firmware via Revolver 1.1.1, I just booted up my TF after an hour of it being off and connected to the A/C outlet to see how much it had charged. It increased 2% in the past 70 minutes. Something's Fishy here.
did u guys try method of hookin to your pc, then turn on usb debugging.
i havnt had any issues recharging since this thread was made
I connected it to the computer a few times and USB Debugging was already on, I just turned it off and I'll try and connect it again but I'm currently backing up stuff with CWM.
Edit: I just cycled USB Debugging a few times while it was connected to my PC. XP (virtualized through Arch Linux) recognized it each time, but still no change in the charging status. I'm going to unroot and go back to the stock 3.1 to see if it's a software or hardware problem.
Edit: seems to be a hardware problem considering I reflashed it back to stock (unrooted) and it's still doing it. Awesome.
Same problem here. All of a sudden I didn't see any status from the dock battery (dual battery widget). Tablet charges just fine, but the dock won't charge. even left it connected to charger overnight but the dock led just keeps blinking orange (/red). I'm afraid the dock will have to go RMA.
Just got an email back from Asus and they told me to fill out an RMA. It'd be nice if I got one out of the B70 batch as a return
edit: sadly, that didn't fix it. I re-rooted, let the battery drain down until it turned off and wouldn't turn back on, then let it charge for 2 hours. I turned it back on and the battery was at 5%
Anyone know what the solution is to this problem?
When I plug in my NC to my computer using a standard micro-USB cable, whatever state the battery is in, it instantly indicates 100%.
For example, right now it is plugged into the computer and the battery was at abou 73%/3900mV when I plugged it in, and it instantly indicated 100% (still 3900mV).
The only solution I find is to just let it sit and charge for hours until it's back to 4200mV and then reset the battery stats using BatteryCalibration app.
Why is it doing this? Can I stop it?
Thanks!
I recently updated to encore 253 and have noticed the same thing. I don't remember this occuring with 177. From what I gather there probably won't be anymore CM7 updates as all resources are now being devoted to CM9.
Well I am not running the nightlies. This has happened with two builds, the 1/13 build I am running now and the 12/13 build (or whatever the mid-Dec build was) it happened a couple of weeks ago.
Strange.
I had a similar problem with a broken cable. Do you have another micro-usb cable that you can try to see if it's the stock cable? New cable fixed my issue.
It's happened with two different cables. Possible they are both bad. One is the one I use with my phone all the time, it's never done this with my phone.
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.
I have had ongoing charging issues.
My original micro USB charging cable stopped functioning after some time. I switched to another one that worked very well for a few months. Than that one stopped working. I would plug either one in and it wouldn't recognize. I finally wrote it off as a faulty micro USB port so I ordered a POGO cable.
I got the cable yesterday and it started charging immediately. I got up to about 37% and than charging stopped. I unplugged, replugged, rebooted, etc. I left it on the charger over night. It's consistantly loosing power. I even tried switching it off and than charging without being booted. The battery charging indicator would come on, show the charging animation than disappear and continue to die.
I'm getting quite frusterated at this point. I am running CM 10.2. I have a sneaky suspicion that the culprit might be a corrupted part of the rom. My next step is to try things like factory wipe or flashing a new version of a rom. If that doesn't work, I don't know what else to try.
Any ideas?
Solved
It turned out to indeed be some problem with the rom. After doing a factory reset, it started to charge in the correct direction. I'm now at 100%.
Out of curiousity, does anyone know what would happen to a rom to make it drain a batter, even when connected to a charger?

If for some reason it is using 100% of its CPU, the Nexus 10 can potentially draw more power than the microUSB or Pogo chargers can provide.
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.
