I was wondering if I saw the same battery flattening on my iPhone 13 on Sunday.
I noticed that the phone, which was receiving a charge from the motorhome, had a nearly flat battery at the end of a 70 mile journey.
I had guessed that I hadn’t plugged it in properly but maybe, just maybe, the app was consuming lots of power?
I wonder if I was maybe also recording the track, too? If so, I guess that uses more power???
I’ll monitor it and report back. Hopefully it was just user error on my part.
