My Huawei Ascend G620s-L01 currently with the latest daily build of LineageOS 15.1 (2019-05-17) doesn't detect when the charger or data cable is unplugged. instead, it stays in the charging mode until the battery runs out. If I try to turn off the power it goes to a boot loop with the charging display showing for few seconds before booting again with the same results.
LineageOS 16 beta seems to handle this bit better, but the hardware seems to think that the charger is always plugged in.

I looked in the previous threads about non-booting but no one I could find had my issue. Bought the Nook HD+ about 4 months ago and rooted it and installed Android (not sure which version but cm11). Out of the blue, last week I pulled it out of my bag and the battery % was flipping between 1% and 31%, so I put some stuff on it via USB and then shut it down to charge. I plugged it in overnight and tried turning it on in the morning. All I was getting was the low battery picture, so I kept trying to charge it, but it wasn't charging, the power light would go to orange when I plugged it in, thena fter 3-5 seconds it would flip green and then turn off and retry. My assumption is the battery is dead, but it could be a corrupted OS now as I got it to charge long enough to get to the CM11 boot menu. But I even went out and bought a new charger and converter to rule that out and it still is stuck in the same boot sequence. I obviously can NOT charge this thing while it is off because of it's reboot loop, it can't charge. I'm not quite sure what is going on or whether it is a battery or boot issue but after I leave it for a big it freezes on the cyan picture (which is frozen on some scrambled version of it) until I turn it off.
I can't power it on enough to charge it to rule out the battery, I tried holding the power and n button for 3 seconds, letting go of the power, and then pressing it again to get into the recovery menu, but that isn't working either. And I prepared another SD card for a second flash for a corrupted OS and that didn't seem to work either.
I'm stuck here and I'm not sure what to do now to get it running again. I don't care about the data on my tablet at the moment.
Try plugging it into a PC USB port over night.

That's what I did that got it charged enough to get to try to boot, where it now shuts down. But now as it tries to boot it reboots, maybe from too much power consumption? I only had it plugged in for half hour or hour before that got it charged to the point where it boots to the logo screen. I have a feeling it is not charging because every reboot the light turns off (orange light stays on for like 5 seconds)
I will plug it in to my PC and charge it overnight and let you know what happens. It's interesting, I plug it in now and the orange charge light comes on, shows the Nook screen, then shows the low battery screen and shuts off, then the orange light turns off, but it remains plugged in... not sure if it is still charging but as I said, I will leave it overnight and see what that gets me.
No success. I can turn it on and the charging lights turns on for 5 seconds and shows the nook screen, then goes black and shows the low battery screen, then immediately shuts off and the charging light turns off and it no longer charges.
Any other suggestions? I can't seem to do anything with the Nook now.
Good evening
I have a small problem. After flashing CM12.1 I can't charge the device over USB when turned off. The charging screen appears and dissapears after some seconds. And it does that as a loop because it always vibrates before the new screen appears. However using the wall adapter the devices charges without problems. I've used the CM12.1 nightly which was flashed with TWRP including gapps.
Does anyone of you know a solution?
I've still found no workaround or solution for this issue..
Hi everyone! Today a very strange thing happened... I was using my tablet with Windows, with a usb hub attached to use a simple mouse. This hub has a micro usb output, so that I can charge the tablet while plugging in usb devices (that's exactly the one techtablets uses in one of his videos about this tablet). All of a sudden it stopped charging, so I tried rebooting: NOTHING. Then I switched to Android, but still no luck!
I'm happy I see that it charges if it's completely off, but I don't think it's normal!
What do you suggest me? This tablet is fundamental for me, as I study with it!
Anyone who could kindly help?
Same here and notice this after your post here. Windows notice that i plug in the charger (screen brightness was different with pluged in charger) but doenst charge.
I'm thinking that it might be BIOS related... Unfortunately I can't update it (I have 2.02 version already), or at least sort of reflashing it, cause I don't have a usb keyboard... Can you make a try? Cause it's weird it happens on both Windows and Android! I also noticed that if I have it off, charging, right when I trigger the power button and the teclast logo appears, right before the choice of the OS, it stops charging..
i have same problem, do you resolve it for present? how do you use your tablet?
Mine was a bit temperamental and as described above for the 1st 6 months but now it will not charge even when off unless it is left for days. Then no where near full charge.
I had very similar problem on my old teclast c6j6 tablet a year ago .
It seems my usb connector in tablet was too loose after few months .
I opened and pressed ( squeezed ) usb connector and was work again fine .
For the time being I connect and disconnect usb cable very gentle on all my teclast tablet and is fine .
I have the same problem. The tablet will not charge while powered on and starts charging right away as soon as it powers off. I do not have to wiggle the cable or anything. ON = not charging, OFF = charging. It's very unlikely that this is caused by a bad connector.
Be careful when you use Android. If Android shuts down because the battery is low, the tablet will start as soon as you connect a power cable. The tablet starts up, stops charging because of this, shuts down because the battery is low, starts charging as soon as the tablet is powered down, starts up, stops charging, shuts down, starts charging, starts up, stops charging and s on. Viola: you have a boot loop.
I wrote about it here: http://forum.xda-developers.com/x98-air/help/dead-battery-bootloop-t3243993
There is a fix which requires some soldering. This is a YouTube video which describes the procedure:
Hi xda
Been running my Mi5 for a while now, and loving CM13, but I am having an issue with charging from anything by the OEM USB charger.
When I use any other wall-plug charger (HTC, Sony, Surface Pro4 Brick) the phone will begin to rapidly switch between charging and non-charging states.
This happened with the stock MIUI, and now CM13, as well as in bootloader, recovery and when the phone is off.
I had heard that this can can be an issue with the OEM cable, but have now repeated all my results with a 3rd party cable.
Sometimes a similar issue occurs when connected to a PC, with constant disconnect/reconnect (Around once a second), or otherwise I only get 'slowly charging'.
Strangely, the only device which can charge my Mi5 at a steady, consistent, rate is my Juiced power brick (so long as its the only device connected) http://www.juicedsystems.com/24000mAh-External-Portable-Battery-Charger_p_31.html.
Any ideas?

I suppose the charger you have problems with are the one's with less then 1Ampere.
Try using a 2Ampere charger, that works great for me.
Hmm, both are rated at 1.5, but I'll see what I can find. Thanks
I am running pixel experience (pie) on my device.
I am not able to charge my device until i restart it. As soon as i plug the charging cable out while i am charging it ,BOOM now it will not charge until i restart it while it is plugged in.
**NOTE:- I don't think it is a rom based problem as i am facing same problem in recovery as well as bootloader.
