Hello

I have an iphone xs

When using snapchat telegram or facebook the phone gets too hot. Even while playing some games the phone becomes extremely hot and lags constantly.

I checked panic log and it says

"i2c3::_runInterruptMode Timed out waiting for interrupt; last write status 00200118 int shadow 00210100 xfer 00000000 fifo 00000022 for device display-eeprom\"

Can anyone tell me what that means.

Thanks

You might want to try a new Lightning Port Flex (or one that is known-good) to see if that solves the problem. If that doesn’t work, then consider the following suggestions.

Start by testing a bare-bones setup. Disconnect the battery first (always!). Then disconnect the digitizer, LCD, front camera, rear camera and home button extension flex. Now re-connect the battery; you should only have the battery and Lightning Dock flex (new or known-good) connected. Connect a known-good, preferably Apple-original Lightning cable to an iTunes enabled computer.

Does iTunes recognize your phone? If so, then you should re-connect one flex at a time until the phone stops working. I would start with the Home button flex first, then add the rear camera, LCD & Digitizer then from camera flex.

If the bare-bones setup does not boot, then you most likely have a logic board issue. You could send it (or find a local) to a repair shop that specializes in micro-soldering repair. Sometimes the fix can be straightforward (i.e. a blown filter) and relatively economical.
