Battery replaced but now phone is getting extremely hot & rebooting

hello Nikolas,

What alcohol did you use? If it's isopropanol, you don't have to worry (it's non-conductive and is used in microelectronics very often). The heating of the phone is a symptom of a thermal short circuit, it occurs in the case of a direct connection " + and - " Unless you're into microelectronics, you might find this difficult to find and eliminate (some expensive equipment and skill required). Find a good repair service, someone will find this circuit and repair it for you.

How to Fix an Overheated Phone and Keep It Efficient

Remove the phone's case.

Switch on airplane mode to disable all connectivity.

Move it out of direct sunlight.

Direct a fan at your phone (but don't put it in a fridge, freezer, or cooler)

Reduce the display brightness.

Regards,

Peter
