Hotspot was between the first charge and second charge and I charged all night then until 100%. It lasted until 19 pm with 16% with 7:10 hours of usage. I’ll test my iPhone againWhen you say you were on hotspot, was that after the first of second time you charged? It looks like after the second charge, you had about 6 hrs 49 mins on 80% battery usage. At 100% battery usage, you would get abut 8 hrs 30 mins. This is good. Might want to start posting your battery usage charts with "SHOW ACTIVITY" selected, which shows how much time was spent in each activity.
