After upgrade to IOS 13.3. My iPhone XS (GREY BLACK) was a totally nightmare.
My battery keep on draining even single minute, 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 applestore, 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 after firmware upgrade
They also denied downgrade the firmware versioon.
I appreciate you look into this software bug that haunting everybody.
- I disabled face ID function, the battery keep on draining.
Apple is relatively unreliable these days, they are moving backwards. Counter staff having poor knowledge from technical perspective, unable to attention to my queries and attempt to cover up the story.
To conclude this drama, they in store staff unable to rectify and confirm with me by changing hardware or battery will resolve the issue. But they remain silent and denied the software issue.
They even ask me to fork out 800 bucks to get the phone a replacement change.
If you look into online, there are tons of people facing the same issue. I had my phone charged to 100 %, on airplane mode, low battery and WIFI on. Background apps is all killed, 5 hours down the road on standby, my phone were battery slashed
to half , I wish I could go back older firmware
