No, SoT doesn't include charging. That would be ridiculous if I was running about telling everyone i get 10 hours SoT but I was charging my phone in between 😂
The guide i showed an example of a typical day of frequent charging. When i test my SoT probably once a week or 2, i charge up to 100,then drain it down to 20%.
I get 8-10hours from 100-0. Well technically i get 8 hours from 100-20 then i assume that the last 20% i could get 1-2 hours. So i call it 8-10.
If i was charging in between then that wouldn't be SoT relating to battery life. My actually SoT usage can be over 12 hours a day, but my battery SoT is 8-10hours.
Btw in that post i said i get 6-9hours, that was before android 11, since then its gone up to 8-10, that's mixed usage, YouTube, gaming, browsing, etc... That's why it varies from 8-10
