Frustrating Galaxy Z Fold 4 battery life issues and bugs crop up in One UI 5.1 and March 2023 update
Now, according to the Galaxy Z Fold 4 US user, the battery of his foldable phone is rapidly dropping without any use. Yes, you read that right, he noted “After updating my Fold 4 to 5.1 and also the March security update (F9360ZSS2CWBA) my phone has a very big battery issue. I charged my phone to 100% before I sleep, and it dropped 47% to 53% left after my 6 hrs of sleep. I didn’t use my phone at all. Normally I do not need to charge my phone during the day time in the past 6 months of using the phone, I have to charge it 4 times now with the same pattern of work.”
Earlier it was reported that the battery draining issue with One UI 5.1 also appeared while usage for the Samsung Keyboard. As a solution, Samsung’s live chat support suggests clearing the cache and data for the Samsung Keyboard app and restarting the phone. To clear the Samsung Keyboard cache go to Settings > Apps > Storage and tap the Clear Cache icon. To clear Data, repeat the steps and tap the Clear Data icon.
