I bought a used GS6 a few days ago and several times the phone has either randomly rebooted, froze up, black screen, laggy etc. Several times when this has happened it appears as though the phone is still on but there is a black screen. Other times the phone just shuts completely off as far as I can tell. When this happens sometimes I can power down with pwr+vol down and get into the service screen. Other times I can't do anything at all with the phone for several minutes. In all cases when I plug it into the charger and let it charge a while it seems to come back to life.
At first I assumed this was a software problem, but after 3 data factory resets that does not appear to be the case. The problem crops up almost right away after the reset.
Then I noticed these issues always seem to start happening when the battery level gets down to about 65%. This is consistent. I can find no other consistent reason why these problems happen. When the phone is fully charged I don't seem to get these problems.
Any ideas what could be the actual problem (bad battery, bad main board, bad...) and any solutions? Thanks in advance.

I've been running CM 10 on my phone without issue (besides the whole touchscreen thing that wasn't a big problem for me) for several months.
I went to cm10.1 last week and my phone started having graphical artifacts on occasion (like an overheating gfx card) and eventually started shutting off randomly and restarting with 50% less battery than it had. I did a full wipe and put back on CM10, but it's still doing it, and has gotten progressively worse.
For the past couple of days my phone would work for about an hour, and then shut off and either come back on with 50% less battery, or not at all until I plugged it in for several hours (even if it had just been plugged in all night). Now, my phone has been plugged in for 24 hours and I can't get it to turn on at all. I've held the power button for 30 seconds, held power+down, etc.
When it was on it's last legs I wanted to do S-OFF and then go to stock so I could do the warranty, but the S-OFF process hanged when trying to push the first file.
Any help?
Thanks

If it won't power on, screen won't turn on, power led doesn't light up even when plugged in, it's bricked. Sounds like you've got some serious hardware issues.
A few days ago, my phone got pretty hot while I slept. But everything seemed fine until last night. I only bring up the heat because that's literally the only thing I can think of that might have caused this problem, even if there were a few days between that event and when the phone started behaving strangely.
Status:
Verizon SGS3. On CM11 nightly from about a week ago with the kernel it came with.
Issues:
I can't boot the phone. It'll quickly show the Cyanogen logo and then shut down again. Even if I'm on the charger, it'll just shut down. The battery will sometimes show 0% and charging, then I'll try it again a couple of minutes later and it'll show 87% and charging.
I did manage to boot the phone a couple times. It lasted long enough until I was able to get to the main screen. After a couple minutes, the power menu started flashing on and off showing the reboot/screenshot/power off menu. Like very quickly. Then the screen started turning on and off rapidly.
One of the times I managed to boot the phone, I was able to do a factory reset from settings. I reset it. The problem persists. I've tried two different batteries. Both batteries work fine in another SGS3 I have, but not in the one that's causing all the problems.
Any ideas?
I have a P900 that was left in a drawer for 2 or 3 years, never getting charged even once in all that time. Turning it on, I immediately realized something was wrong because it took forever to boot. The lock screen was so slow that the entire machine locked up for a few seconds, scrolling between pages on the launcher stuttered hard or locked up and everything else with the machine was generally the same. The web browser is unusable, even typing in a URL locks things up. The device is unusable.
So I thought the battery was obviously damaged, even charged at 100% it would be flat for sitting for maybe 2 hours with the screen off. I tried several cycles of charging to 100% then discharging and back up, but nothing seems to help. I don't have much money so I took at stab in the dark and got a cheap battery from ebay and it didn't help. I don't know if this battery is new, but it does seem to hold a charge like the device did when it was new but it's just still so slow that you can't use it.
However, one thing that I've noticed is that apps that don't touch the storage seem to work OK. I have a Spectrum TV app that once it starts up seems to be okay, but not great. Netflix seems to be okay as well after starting up. They both stutter a bit and rarely freeze. I don't know if this is relevant at all.
I'm at a loss of what else could be damaged or how to fix this. I'm in the process of cycling this new battery up and down, though I don't know if this would actually help. I just don't know how to diagnose this problem.
Okay, the problem was the battery, it just took a few hours of charging. I guess now that it can see it has a fully functioning battery that it's running as it should now. Android really should give you an error message about that instead of just slowing the whole thing down to a crawl, leaving you scratching your head.
This strange thing happened to me also.
I was given a tablet that was not in use couple of years. It takes about one hour on charger to start booting at all, I was thinking that it don't working at all.
Then it sits on Samsung Note Pro logo about 15 minutes, then logo changed to Samsung and it took about 15 more minutes to boot in home screen.
Then i realized that it's very slow and unresponsive, I charged it to full and reset, but it's remain the same, very sluggish.
Tried everything, reset it couple of times, flash rom with Odin, nothing helped.
After couple of charge-discharge cycles it starts to work like new!
I would never have thought that the battery could do that, but there it is.
Hi,
Last Thursday night my pixel 2 became unresponsive, I rebooted and it worked again, then it became unresponsive again, I rebooted but to no avail. The phone does have a large chunk of glass missing in the bottom left below the screen (https://drive.google.com/open?id=1NdlE-Xrwa9rPPGpMXT47FHqLWfW0MHd2), this happened due to a drop some time ago. At the time I tried booting into safe mode which didn't help, I also tried to go into recovery mode to factory reset the phone to rule out any software issues, but the phone wouldn't enter recovery mode, it just would go straight to the "google" logo and then would boot loop and sometime it would break the loop and just boot as normal. This unresponsive behaviour has been demonstrated before, but a reboot sufficed.
As the phone appeared to be functioning otherwise, I decided to order a replacement screen (I haven't received it yet), although I do find the ability to not go into recovery mode concerning.
Also, when I say unresponsive I mean just to touch, the fingerprint reader still lets me pull down the notification bar; the phone is not frozen. One final thing and I'm sure if it's related, is that I was getting some crackles and pops when using my headphones with the provided 3.5 to USB C, I assumed it was down to the cable getting damaged, but it might also be to do with phone's damage.
I hadn't touched my phone all weekend, I turned it back on last night so my alarm would go off this morning. It did and I was to my surprise responsive. I left my phone to sit on my desk over the weekend and I believe the battery drained completely and it turned off, I'm not sure if that complete battery drain was the reset it needed or what. It was definitely unresponsive for half a day of me rebooting, but who know how long that would have went on for.
I'm not sure now if I should replace the screen, I think I will just due to the physical damage the phone has, but I would want to return the screen if the phone is on the brink of being unusable regardless of the screen/digitizer hardware. As clearly the hardware does still work.
Any advice/help would be much appreciated
I have a HTC 10 (new old stock) that I have been using for 2 months, on stock Oreo.
Everything was fine until last week when suddenly in the middle of reading an email the screen froze, a few seconds later the screen went black and would not boot up. Nothing at all, not even with a hard reset VOL DOWN + POWER or VOL UP + VOL DOWN + POWER. Tried holding it for A LONG TIME like 5 minutes, no luck. The phone had a hard brick and that's it.
Occasionally, after a few hours, I would try to reset it just for the hack of it. Or connect it to a charger (no charging light) Eventually after about 20 hours, it booted up again after I held all three buttons for a few seconds. Then it worked like nothing has happened.
It kept running for several hours, I charged it up to 100%, ran down to about 80%, then the screen froze again and died. Same thing happened, won't boot up at all. But if I wait another day or so, kept trying, it will boot up again.
I know the HTC 10 is known for it's horrible battery drain issue, and I have experienced that myself with another HTC 10, this is not it. The battery is running fine on this one. This is something else.
After doing this for a few iterations, I was able to figure out a pattern.
When the screen froze and the phone dies, it will not boot up no matter what you do. But for some reason something is still going on as the battery is still being consumed, a day or so later, when the battery is completed depleted down to 0%, and as soon as it hits 0%, whatever causes it to not boot unlocks and allow it to boot again, as long as you have it on the charger, the charging light will come up at that time, and as soon as it gets a little bit of juice, it will boot up again normally. Except when it does boot up, the date is reset to December 31, 1969 7PM.
After testing this for two more iterations, I am reasonably sure this is what's going on. Then I did a factory reset.
Once it's factory reset, I did nothing except turned on WIFI and didn't do any further setup except surf the internet a bit on WIFI, and about 10 hours later, it died again. Now I know, if I leave it alone for 20 hours, then plug it in for a few minutes, it will boot up again.
So here are my questions.
(1) The phone appears to have bricked during the 20 hours that is was totally non-responsive. What is happening that's consuming the battery?
(2) Does this seem like a hardware issue or software issue?
