Howdy folks,

My S21, current OS patch version, randomly started overheating and battery draining very quickly last week. This was an abrupt change in behavior. I factory reset my phone. That fixed it for a few days and then this issue reappeared. I cleared my partition cache, no change. I swapped my battery for an OEM battery at a shop. No change. Accubattery and Devcheck both say no app is draining any CPU, RAM or power unnecessarily. This has to be a droid OS issue. Apparently late last year around One 6.0 some bad stuff happened and I have now been affected and cannot find any resolution. My phone now has to be on a charger 24/7 for normal use. The heat alone will end of life the device prematurely. Totally unacceptable.

Help? Much appreciated.
