[Q] Sd-EXT problems lead to awful battery issues? help?

My phone had been having issues accepting the various modems I tried to install on a recent CM-10 upgrade. Prevbiously had used ROM Manager allmost exclusively until I heard that it was horrible and messes up a lot. Was having an omnipresent sd-ext issue. Also wiped battery stats as I had someweird charging issues where it the battery level when not turned on was not even close to the number tha appeared when it turned on.
I have been wiping every time I update etc as my battery had been acting weird. I had been having problems with the phone reading the [Sd-ext] like it wouldn't see it, but still could access it. So I reflashed to stock and rerooted, however the battery. I figured it was time.
well now the battery shows full, but if I untether from the usb link it wont start on its own. if i "jump start" it with USB power it will start but eventually die and flash to battery charge, or just die immediately when I remove the usb cable. I've been running cm-10 mods, but the issue seems to be worse now that I am rooted. I am thinking I'll reflash to stock and try installing CM 9 stable and see what happens, but if anyone knows a better plan I'm all ears.
FWIW when I am in download mode with the battery in it still works even when not plugged in.
Thanks in advance!

Weird screen problems

I'm having a problem with my Verizon galaxy nexus. The screen goes nuts with phantom touches. Happens a couple times a day. If I turn the screen off, then on it fixes it for a couple minutes. Rebooting fixes it for a few hours or more.
I factory reset, updated to Codename 3.8 from 3.6.6, tried different kernels. Have the same problem. I did restore with titanium backup, would that have brought the problem back if it's a software problem?
I turned on show screen touches in developer options, to make it easier to see when this is happening and what the problem is. It usually shows 1 or 2 extra touches, sometimes more.

Coming from a clean install?
Get the phone back to original software, lock him and unlock later (that erase everything)
Then install CNA or other rom you like.
(sorry for the bad english, just wanna help)

I think I narrowed down the problem. I think it happens when the phone is plugged into the charger then gets to 100% charged.
When I unplugged the phone when this is happening, but leave the screen on, it keeps going til the battery goes to 99%, then starts working normally.
I'm not certain yet cause it doesn't happen every time the phone is 100% charged, but that seems to be the only time it happens.
Edit:
It also happens when the phone is less than 100% charged and plugged into the charger when usb fast charge is enabled.

Powering off by itself

My Note 2 has suddenly started shutting off by itself. It started right after a charging glitch. I loaded up a new kernel and was charging the phone up. At almost full charge it went into download mode. It took a few battery pulls to get it back into recovery where I wiped caches and rebooted. Since then it shuts off by itself every hour or so. I full wiped and re flashed the rom with its stock kernel and the problem is still there.
Any ideas? Hardware issue?

Random reboots is usually software related,mine was happening because i UV too low or OC too high like to 1.9

Phone will not wake from sleep, needs reboot, massive battery drain

So, a few things: First, I used Sunshine on my phone last Wednesday to put the newest T-Mobile firmware on my phone. Prior to doing these two things, this problem did not exist. I am on ViperOne 3.5, chose T-Mobile as my carrier and was very careful in setting things up.
First two or so times I would notice my phone was not waking up, so I held down the power button to restart and after it turned on there was a very large battery drain (30-50%). After this I decided that maybe the firmware was the issue, so I fastboot flashed a fullwipe version through fastboot (originally I had done a no wipe flash) and restored backup nandroid from TWRP. After that the problem persisted, so I thought maybe it was a rom conflict and did a clean install of Viper 3.5, thought everything would be good but while in the car it did it again. This time I caught it quick (I had used my phone maybe five minutes before and when I restarted the battery drain was less than 5%. But seeing as I've done a clean install of both the firmware and the rom now, I'm sort of at a loss for what to do.
Has anyone heard of this, or would anyone have tips on what to do? Can provide additional info if needed, just want to get this worked out. I've been lucky so far and it's done it while I didn't need power. If it were to do it during work when I can't check the phone for a while, it could lead to the entire battery being depleted.
::EDIT:: I should also add that this happened once when I was asleep, and I found that the phone would not charge when in this state, as the orange light was not on when I woke up and I had to reboot the phone. Again, extremely weird and it only started after Sunshine and firmware change, nothing else.

This "sleep of death" thing has happened to me a few times, though I have not seen the battery drain. I have not figured out what is causing it.

I actually just caught it and tested some more out. Tried plugging it into a wall and it won't charge. Also tried plugging it into a computer and it will not recognize. The only two things I have changed are the firmware version, and running sunshine through it. I'm actually pretty worried since it won't even interface with a computer until rebooted. Also went from 90ish% to 77 in a matter of 15 or so minutes

SM-G920P Random reboots

Hello everyone. I have a problem with one of my phones. This galaxy S6 started to reboot randomly. You can see how it reboots in the video below. The CPU temps are ok, i tested it in heavy load (usually stays at 60-80C in benchmarks, and below 60C under normal use, idle temps are 30-25). It doesn't crash specifically in heavy load, it can happen even in idle. I have tried different stock roms, full wipe of internal sd card, custom roms and nothing helped. Usually in custom ROMs the phone random reboots not so often. This phone is not water damaged and has not been dropped. Is that a battery failure or what it can be ??
Any help will be appreciated.

I forgot to mention, reboots happen more often when battery is under 40%.

I have this problem too, I'm not sure if this will bump the thread, but if you ever solved this problem, I would love to hear how! I got mine used to idk the history. I rooted it as soon as I got it and the problem didn't start til a month or so later. I have tried two different roms and both seem to have the problem. It started with just the occasional crash when memory was loaded. Then one day it started crashing every couple minutes so I tried to restore from TWRP backup. The restore failed and it could no longer boot into the OS. I then flashed a new rom and it is currently trying to configure it (the flash worked) but it is still crashing randomly. It seems to happen every time the screen times out as well as randomly.
