Battery drops, random reboots and freezes on LilyGO T-Embed (also affects M5Stack)

[TheEvilAstroCat]

Problem description

I am using two devices: LilyGO T-Embed CC1101 and M5StickC Plus2. Both of them experience sudden battery level drops, regardless of the actual battery charge.

Additionally, the LilyGO T-Embed shows more severe issues:

• the device sometimes restarts randomly without any clear reason,
• when launching applications that use Ethernet, RF, Wifi, etc., the device may completely freeze,
• after such a freeze, the only way to recover is to physically disconnect and reconnect the battery.

The device might freeze if Th e Ethernet module is not connected this is fixed in #1868

I have the same issue with the battery (also on version 1.11.1). It suddenly dropped from 95% to 6%. For now, I’m not experiencing freezing problems, but I still need to run more tests.

the fix is disable pmic reading battery while using high current pulling module.

@emericklaw In version 1.12 the freezing issue still occurs on the LilyGO T-Embed CC1101
