Installed iFixit Battery, now indicator stuck at 100% & random reboots
As the title says, I just received an iFixit iPhone 6 battery to replace the dying one in my iPhone. I've done many replacements on iPhones so this was very straight forward especially with the tools from iFixit. Upon turning the phone on it would do a few random restarts then settle down which I thought was strange. The LCD also showed faded white blocks on the top of the status bar but after searching people said those blocks would disipate and the screen would go back to normal which it did within a couple hours. I took the LCD and battery cables apart, cleaned all contacts with a soft toothbrush and a tiny bit of rubbing alcohol on the brush, checked all contacts for damage, and reseated the connectors making sure full contact with the logic board happened but that didn't seem to help.
After 2 cycles the battery indicator gets stuck at 100% until I fully reboot the phone (not respring) and it resets to the correct indicated battery level. Once I reboot the phone, it'll go into a boot loop for a few minutes and settle down again. Indicated battery behaves correctly until I charge to 100% then it gets stuck again. I'm testing now to see when my phone will turn off. It's been stuck at 100% for about 12 hours now and plugging it in says the battery is fully charged, thus not supplying any charge current. I know if I reboot the phone it'll charge after a few boot loops.
This never happened before, could it be a bad battery or the battery that I had always dreamed of staying at 100% forever? Haha. Everything else works as advertised from Apple.
