IOS 26.1 Issue

Same issue on iphone 17 pro max after updating to ios 26.1 public beta

Something is really strange with the battery on my iPhone 16 Max running ios 26.1 prerelease beta. Yesterday morning I made a 1 hour facetime call (my phone was at 98% before the start of the call). After the call finished, I terminated (swiped up) facetime, and then checked Battery. It said that facetime had used 11%. About 1/2 hour later I checked battery and it said that facetime had now used 18% even though it still said that it was 1 hour on screen and 0 background. About 2 hours later, battery said that facetime was up to 20% with the same on screen and background. In desperation I deleted facetime from the phone, reinstalled in from the App store and restarted my phone. An hour later it reported "Recently deleted app" was now up to 30%! Either something is buggy with the battery reporting or something is really wrong with the ios operating system.
