So last night before I went to sleep, my NT had about 40% battery life left in it. I'm currently running the final alpha build of CM7. I've been experiencing really bad wifi loss issues and have kept the 'Never' option enabled under the wifi sleep policy (thinking that would help hold the connection).
I woke up to find the NT was turned off. Figured that was odd as I was only asleep for about 5hrs. I turned it on and then noticed it got into the OS and then died. I did see the battery icon was red briefly.
I then plugged it into the wall and it was boot looping. I saw the 'n' logo pop up, screen went black, 'n' logo, etc. etc.
After numerous attempts of holding down the power button for 20+ seconds, holding power+vol down for 10 seconds, plugging it with or without an sd card into the wall and computer, nothing is happening.
The computer does see something as I'm hearing the common connected/disconnected tone from the USB port. Now I'm noticing that plugged into the wall, the 'n' on the cable stays orange. It never turns green.
Did it go 'poof' in the night somehow?
[EDIT] Ok after leaving it plugged into the wall for about 15mins, it suddenly turned on but had a google framework FC error. Yeah, not sure what I should do at this point. It appears to be charging...
It's been noted by others that if the power level goes below 15% you mustn't turn the device off if you don't have the original charger nearby. If it dies you need to charge it with the original charger for a bit before it'll power back up.
I assume this means that you can't run it off the cable while you've got a completely dead battery. That kind of stinks but isn't too surprising, a lot of devices are like that.
So does that mean that if the device is <40% of battery I need to plug it in if I won't be around it for a while? Not sure I'm cool with that. Battery life was great all day yesterday but somehow it dropped 40% in under 5hrs while asleep.
I can't really say much as I haven't dealt with it personally. People were talking about it in a couple threads about the NT's charger and unique 12 pin cable.
Here's what I understand from what I've read:
You can run it until it's empty all you like. You'll just need to use the Nook's factory charger (or a compatible 2A charger with bridged D- and D+ pins) AND (this is the important one) the factory USB cable to charge it.
If you run it until it dies you have to charge it for a little while before it'll turn on again, BUT you have to use the original cord and charger. It won't charge off of a regular micro USB cable nor will it work if you're using a 2A or smaller charger that doesn't have the middle two pins bridges (the Apple UBS chargers won't work nor will your PC's USB ports, for example).
The NT will charge, albeit slowly, if connected with a third party cable or USB charger (without the data lines D- and D+ bridged), but not if the device's power has been depleted.
So I suspect something sucked up a lot of juice while you weren't using your NT. Not a huge deal, but definitely annoying. Plug it in for 15 minutes and you can get rolling again.... BUT only if you're using the original charger and cable. Lovely isn't it? It's not a huge problem but it is annoying. I wish you could at least use the device with a dead battery while plugged in.
I just mention the charger/stock cable thing because I'm sure someone will probably see this post in the future and may be having that particular problem resuscitating their NT.
Cool, yeah I don't specifically set out to run it down to zero but since the device is clean with minimal stuff running in the background, it's difficult to know when this might happen again. I assumed I'd wake up with like 20-25% battery left. The framework FC is also something I'm concerned about but maybe it was just a fluke.
Ah well, really do appreciate your input and I'll be sure to keep the stock cable/adapter on hand when I'm on the go.
Battery showed fully charged, I rebooted to do another CWM backup and then when it came back up it showed 84% charged. Lol. And this pic made me laugh even more. Time to get that lady from Poltergeist involved I think...
The Google Framework force close is typical of stock rooted NTs. I don't believe it ever did any harm to anything though. Just that it sometimes appears on reboot.
I'll ask one additional question as to not make another topic since it's related.
Opinions on battery calibration with the NT? That was one of the reasons I didn't charge it last night as I wanted to fully run it down and then fully charge it back up. Does the NT require this with a new rom install? That pic above shows the battery gauge clearly wasn't correct initially.
Your battery is draining overnight because wifi is running the whole time (as you stated in your first post).

That's what I obviously thought of at first but it didn't drain nearly as much when I was using it throughout the day. The only thing I can think of is maybe the fuel gauge itself was wrong from the start, which refers back to my calibration question.
My GS2 has the sleep policy set to 'Never' as well and only loses maybe 7-8% after being asleep for around 7-8hrs and it certainly uses more juice in sleep due to the cell communication, etc.
Hi all,
I have recently come across a problem which I cannot overcome by myself and I would really appreciate your help on this!
Phone:
Galaxy S2 (3 UK)
FW:
CM9.0.0
Description of problem:
My phone will not charge the battery. When connected to a charger, it turns itself on and immediately turns back off as there is not enough charge in the battery.
Events leading to problem:
My phone has been functioning perfectly for about 5 months (on CFW) before this happened. I had noticed that my phone ran out of charge abnormally quickly one day before this problem occurred. I did not suspect anything, and put it to charge overnight. The next morning when I woke up, the battery was out of charge (while plugged to the charger!) and the phone was abnormally hot at the area above the battery connectors. During this time, the phone would not turn on. I then unplugged the charger, and let the phone cool down. After cooling down, the phone was able to boot into the OS, but turns off immediately after that due to low charge in the battery.
What I have done so far:
Following suggestions on this thread: forum.cyanogenmod.com/topic/36648-galaxy-s2-empty-battery-boot-loop/
I suspected that my phone's firmware/kernel had somehow been corrupted. I then stripped a USB wire according to the thread, and attached it to the appropriate battery connectors allowing me to power my phone and flash the FW+Kernel via ODIN. I have since then flashed various firmwares in this order in attempt to recover my phone: Lite'ning v3.6 > Stock (3 UK Branded) > CF-Root Kernel > CM9.1.0.
Current state of phone:
I managed to charge my battery a little via my stripped USB cable, and started up my phone. After booting into OS on battery without charger connected, I have found that the phone will not charge the battery when connecting the charger while the phone is on.
However, if the OS boots automatically when connecting the charger while the phone is off, the battery status will be "Charging", but the charge goes up very slowly. (6% in 20 minutes?) What's even more weird is that if I take the charger off during this time, the phone immediately turns off. While the phone is sort of "functional" now, I'm really afraid that it will recur if my battery ever goes flat again.
I'm sorry this is such a wall of text, but I'd really like to hear your opinions on this. Thank you so much for reading
Did you solved the problem?
I'm with the same problem.

Whew that was long.. but anyway, i suggest you get the external battery charger, maybe it will do you good.
Have you tried going back to stock and doing a full reset?

Have you tried a different battery?
I started seeing a "Slow Charge" notification yesterday saying that I should plug in a genuine HTC charger to optimize the charging time. I normally charge the phone at my PC using a USB docking station and have done this since the phone was new in April without ever getting this notification. Despite the notification, it still seems to charge fine though, although it might be imperceptibly slower, I didn't really test it. I did test with a wall charger and the notification went away (it wasn't the HTC charger), so at least it is checking for something.
I am charging the phone at work today (also through USB/computer) and get the same message, so it isn't just the home setup.
A couple theories that someone might be able to shoot down for me:
I accidentally ran my phone completely out on Saturday, would that have triggered anything? Maybe the battery needs a few cycles now that it has been fully* discharged?
The phone has been fairly warm when plugging in the last couple days (new game ), would that trigger this? It wasn't warm every time though and the notification is still there.
Unlikely, but was there a change with the 4.3 update that might effect this?
*The phone shut off, but I assume that didn't damage the battery since the phone did an automatic/controlled shutdown at 1% or so to go.
USB charges at 100mA and can ramp up to 500mA. The wall charger is 1A and will therefore charge significantly faster. Neither is an issue, but my HTC One has a tendency to see any non-charger as a USB port and therefore slow the charging. Only real problem is driving with GPS running.

Thanks.
Like I said, it hasn't been a problem, I don't even notice the difference in time to charge, it is just that it is new. And after 6+ months of ownership, something new randomly appearing is weird.
It is currently charging in the same port and doesn't have the notification by the way, so it appears random. Go figure.
I agree that it appears randomly. I'm not a fan of this 'feature' that HTC built in. I'm still looking to find out what HTC's threshold is the activates the notification and the slow charge mode. The only charger that this concerns me on is my car charger, but I haven't received the message lately. I also have not used my GPS on a long trip in a while.
Same issue "Slow Charge" notification + No PC connection
I also purchased my phone in April. Just recently (month or so) my phone is now giving me the "slow charge" notification. Also, I can no longer connect to ANY computer. I have tried 6+ computers and none of them recognize the phone. The phone doesn't seem to notice it is plugged in to a USB port either. I have tried toggling the Developer Options and USB debugging without any change. There doesn't seem to be much info on the internet regarding this issue, but the ones that I do find seem to be similar to my issue. This seemed to happen after the 4.3 update.
Are you also having problems with accessing your phone storage when connected to a computer? Thanks.

Hi bigpile,
Did you find a solution for this? It now happens to me too (slow charger notification and no usb debugging).
Same issue..
My HTC just started doing that. Tried all the usb ports on my pc it comes up with a "slow charge" message but if I plug it into a wall charger (a Nokia micro usb on in fact) it works fine.
Main concern is that the phone will no longer come up under "My Computer"
I can charge it fine using the wall charger but it just doesn't want to work through my usb port on the pc (I have tried changing the cable same issue)
Hello,
I have a really weird problem with my phone for several months now. I use Zenfone 5, and my warranty is probably void already, but I could not use it anyhow (it is in a different country). I tried contacting the official support, but they just said to send it in for a check up, which I could not at the time, and cannot now either.
The problem started when I plugged in my phone in my car using third party car charger. It worked with other phones with no problems, and the output should be OK. When I plugged it in, the light on the charger went off, and the phone turned itself off without any notification. I tried to power the phone on with no success. It just vibrated, and remained off. Later I disassembled the charger and found out that the safety fuse has melted.
I went to my house and plugged the phone in, and it turned on. But the problem was, and remained to this day, that the phone thinks it is charging even when it is not plugged in. The phone charges normally, and battery life is ok, the phone normally goes into deep sleep mode.
The phone won't power up without charger, and the USB OTG obviously doesn't work. But there are some curious things about this problem.
When I took my phone apart and disconnected the battery for 30 minutes (it is non-removable), after I connected it back, the phone turned itself on (without the charger), until I tried to charge it, then it went back to only powering on while on charger. The constant charging thing, nevertheless, remained all the time.
Sometimes when I plug in the cheap USB OTG converter, the phone stops charging notification. When I unplug it, it goes back to charging.
I have no clue what could be the problem, and which part (the usb board or the battery) could be faulty.
I also tried hard reset a few times, with no success.
Thank you in advance for your answers.
Bump? Anyone? Any clue?
Is there any way to change kernel so it doesn't register charging if there is no current flowing to the phone?
And which type of battery connector is this?

BUMP
Sooo
Since Ive had it, as long as I remember My Z2 wouldnt properly charge via usb, common but that it wont charge over 85 percent, after that its just sort of "twitching", the charging light keeps blinking like it keeps getting disconnected, regardless of cable/charger. It would still connect OK to PC while constantly blinking, without disconnects. Latest stock rom. Also, Offline charging never worked, it would always boot when plugged in while powered off.
SO, I used a magnetic charger, and that worked fine, no blinking, 100%, until i believe the cable broke. So I went and thought I will try a custom Rom, seems like a software Issue maybe.
Now, on Resurrection Remix, even at low charge, it keeps blinking like crazy, like it keeps getting plugged in, screen wakes all the time, and so it loses charge while plugged in. Tried the QC 2 fast charging kernel mod, but no change. It just keeps alternating between charging and charging slowly, constantly waking the device.
Right now, the only way to add charge is to offline charge, powered off plugged in via usb it works fine
Using the original charger and cable that came with the phone, but its the same with others too. Anybody have a solution?
