Oh would you be willing to share your battery use screenshot under the "last 10 (or 6) days"? I'm really curious to see how you define "light usage"I think it is a little too early to categorically say “rubbish.” We will have to wait and see if the battery is the same size as the current SE, which is 1,821 mAh. Given the smaller form factor of the 5.4”, I am not going to assume Apple will put anything bigger in the phone. The 11 model has a 3,110 mAh and the article says worse than that. For all we know, the battery could be 2100 mAh. If it is the same size as the current SE, a lot of people are going to be disappointed and frustrated.
I have the current SE and it was getting excellent battery life on iOS 13. I am a light user with the phone and I could get almost 1.5 days between charges. With iOS 14 and setting up as new several times, a lot of the time the phone is down to 20 - 30% before the full day is over. I have gone to using a Apple Smart Battery Case. I am using the same apps as I was with iOS 13. It may be a bug with iOS 14.
This is my "last six days" in battery.
