Charge duration of my iPhone 7 dropping fast
Hello:
I have had my iPhone 7 for almost one year exactly. For most of that year, I was very pleased at how long each charge of the battery lasted. But in the past month or so the length that each charge lasts is dropping very rapidly. Instead of charging once every 1-2 days, I now have to charge 2-4 times per day. Can anyone help me to understand (and hopefully fix) this?
Thank you,
Peter
