Battery life is very impressive on my 17 Pro Max.
Charged it to 80% almost exactly 24 hours ago. It’s currently at 39% charge. I’ve got roughly 7 hours SoT using 41% charge. If I really pushed it then I could probably get 14 hours SoT.
And that’s before I need to charge it again and while sticking to 80% limit. Let’s say I charged to 100% then probably looking at 17 hours SoT. Could maybe hit 18 hours if I was using it for long periods at a time but realistically I’m not gonna be using my phone every waking moment.
We truly have 2 day battery smartphones now. Even if you account for degradation to 80% the battery life is still going to be fantastic in 2-3 years.
In my experience the lowest I’ve had battery health go is 88% after 3 years on my 12 Pro Max. My 15 Pro Max was at 93% after 2 years.
If I keep this for 3 years and get to 88% health again then I’ll probably still be able to get 15 hours SoT from a full charge. If it goes to 93% then just under 16 hours.
