but not many I could do when i was already half asleep. So what I went ahead and did was just easy, simple troubleshooting: restart it, Twice. It would charge to 100% when the phone was off, just android couldn’t display the correct battery percentage. I left it powered off cable charging over night, then powered it on in the morning. That seemed to work for me. Weird, but maybe it’ll help. Another thing I saw was clear the cache; that may also help. I myself didn’t do it because sleep solved my problems. Hope something in there helps! And remember: if at first you can’t fix it, google it, then try again (after it led you to an ifixit page).

@ukblueis4ever I recently had an issue with the aforementioned Galaxy Note 5. At the time I didn’t have the device, but I had been told by the relative who owned it that it needed a battery replacement. I’ve been using it for a couple weeks now, and the battery has been pretty good. I’m not entirely sure what to expect, but it could probably do better with a replacement. I have noticed that powering down, leaving it for several hours, and then powering it up again tends to eat quite a chunk of battery. Anyways, one day when I got home, I placed it on a wireless charging pad and left it, probably for several hours. I returned to find it only at 77%. I assumed it was just being slow and left it for, lets say another couple hours. By now it was time for me to get some rest, but the phone was still at 77%. I actually searched up the issue and found an entire article about it. I knew it could be the battery, and I do plan to replace it since the back glass is cracked. Well, they had lots of solutions(next comment)

I have a question. When calibrating my battery ( for a Samsung Galaxy Note 5) would it be bad to use fast charging? Thanks!
