I’m also using an 9yo iPhone 7 which got its battery replaced 7mos ago. I charge it every day because of heavy YouTube usage. It is still on 100% capacity
My SE3, I use for Reddit, Twitter and bank apps only but it was the first on to have its capacity dip before my IP7.
Any thoughts my SE friends?
connect it to the computer and check with iMazing or coconutbattery to see your cyclecount and real degradation of your battery.
Thanks, will try this
