Debugging battery life
I have a factory new MacBook Pro 2019. Supposedly I should get 11 hours of battery life but I don't even get 3. Fully charged at 23:28. Now it's 2:20 with 12% left:
Normal web browsing, email etc, no heavy CPU loads. Inside, the display brightness is at ~1/3.
Device is hot, fan (silently) blowing. I can't find anything suspicious in the Activity Monitor. Idle shows ~93-96%. Largest consumers are WindowServer, coreaudiod and a few others.
Here is CPU History:
The System Management Controller
is responsible, among other things, for the power supply and the battery, state of charge. I recommend you reset the SMC first.
