After upgrade to IOS 13.3. My iPhone XS (GREY BLACK) was a totally nightmare.
My battery keep on draining keep on bugging me, even it's on standby mode. I attempt to restore via iTunes in DFU mode, without any luck.
- Battery health is at 93 %, and I feel the phone is overheating after the upgrade
- After restore 'Face ID is not Available' You can set up Face ID Later when iPhone cool down
Even if I manage to set up the Face ID successfully, it's intermittent working. Messaged reflect on the 'Face ID will be available, when iPhone cool down'
I pop into apple store on 31st December 2019, they claimed hardware is all perfectly fine. But detected error in the sensor issue. They cannot promise me by changing the battery will resolve this issue, it can be damage of the circuit board or Face ID hardware, after firmware upgrade. They also denied downgrade the firmware version.
- I disabled face ID function, the battery keep on draining.
Counter staff having poor knowledge from technical perspective, unable to attention to my queries and attempt to cover up the story by up selling their new products only
To conclude this drama, the in store staff unable to rectify and confirm with me, by changing hardware or battery will resolve the issue. They remain silent and denied the software issue.
They even ask me to fork out 800 bucks to get the phone a replacement change. How I wish I could revert back right now
