Rebooting every 180s - thermalmonitord / sensor TG0B
After having replaced the battery (non-genuine from a trusted seller on eBay), my iPhone SE constantly reboots (seems like every 180s). Took a look in the crash logs and found that the phone is kernel panicking. The error message is something like „no check-ins from thermalmonitor.d since load for 180s“ followed by „missing sensor(s): TG0B“. Also, I am unable to view the battery health in the settings - it only shows a spinning wheel forever.
Unfortunately, I couldn’t find anything related to this sensor. There are some posts on iFixit regarding thermalmonitord crashes already, but other sensors (which are supposed to be related to the charging flex). I didn’t touch the charging port though.
However, I had to apply a lot of heat in order to get the original battery out (used a microwaved washing cloth) - hoping I did not melt anything else in the process.
Does anyone know what the sensor TG0B is and how to fix this? Would another battery work? The old did work before, but after having removed it it’s very bent and I would prefer not to install it again to test, so I’d have to get another battery first.
