Nightly Released 12/22/2015 Fixed Charging Issue

I walked my d855 (LG G3) back through the nightly releases until I found the latest one that did not have the charging issues for me. I ended up with the 12/22/2015 Nightly Build that doesn't seem to have any of the charging issues. I was not able to download the 12/23/2015 Nightly for some reason, I think I just got a 404 error when trying to download the file.

I saw some people talking about the 777 kernel being a solution to this issue and I downloaded the zip file for that kernel but I wanted to see if one of the nightly releases fixed the issue before I started messing around with the kernel. I may end up installing that one if one of the Nightlies doesn't fix this issue sometime in the near future.

For the record, my phone would charge for a short while and then would stop charging the battery. The percentage at which it stopped seemed to be random, it was not the same percentage every time. Every once in a while I could get it to charge up to 100% again but not usually. Most of the time it would stop charging within a couple of minutes of plugging it in or setting it on the wireless charger. It did seem to take a charge if it was turned off. I could only test that with the wired charger since the wireless charger boots the phone up before starting to charge the phone again. Whenever it stopped charging, my 3c toolbox battery manager would say that it was plugged in (or on the wireless) but that it was either at 0mA coming in or sometimes it would actually drop into the negative (discharging).

Around the same time that I started having the charging issues I also ran into a problem where the phone would shut itself off whenever I had Google Play Music running through my Bluetooth headphones for a few minutes. It didn't just shut down all of the sudden with no warning, it would throw up the message box that it was shutting down, just like if I had told it to shut down myself.

I will keep an eye on the 12/22/2015 Nightly release and see if all of the issues I was having with the more recent Nightlies have stayed away. I will post again if I do run into these problems again.

*** EDIT ***

I went ahead and installed the 777 kernel and then updated to the most recent nightly release. I still ran into the same battery issue the first time I tried to plug the phone in. So, in my case at least, the 777 kernel did not do anything to help out the charging problems related to the nightly updates past the 12/22/2015 nightly release.

I am currently restoring my image to the 12/22/2015 nightly release with the updated 777 kernel so that I can charge my phone again. I will continue to check out the 777 kernel but I am going to have to hold off on the nightly releases/updates until they fix this problem. I can't leave my phone off every time it needs to charge. I did order two more batteries with an A/C charger so that I can swap out batteries for full ones if I need to. I originally ordered those when I first came upon the charging problem, mistakenly thinking my battery was going bad.

At any rate, hopefully someone will figure out something for this charging issue soon. I hope I maybe saved someone a little time with this post anyway....
