Hi I have a Samsung Galaxy A25, 111 days old, and used to get a whole day's worth of usage on one overnight charge. However since the last update, One UI 7.0, I cannot get a full day's usage and have to top the charge up in the evening. There has been no change in how I use the phone, and problem noticed immediately after the update. Have also noticed on some forums that others have experienced the same issue. Any ideas what has happened?
