Hello everybody, my X turned 11 months today and atm. I have 86% of battery capacity. Strangely enough, I've always charged my phone between 20 and 80% and never left it charging over night. For almost a year I'm constantly using a AmazonBasics lightning cable and less common out of the box cable. Since I'm an active phone user for Spotify, Feedly, Maps etc. it lasts nearly 5,5 hours and then I have to charge it again. Moreover, after each iOS update especially on iOS 12 beta my capacity dropped 1-2% after another beta upgrade or iOS 12 GM. On iOS 12.0 I had 88% and on 12.0.1 I have 86%. Anybody facing this problem as well? Cheers.
