I have an iPhone SE 2020 with iOS 14.2.
If I turn on Optimize Battery Charging, my phone loses about 40% of its charge while sitting unused overnight.
Anyone else experiencing anything like this? Check your charge before going to sleep, don't plug in or charge your phone, and see how much remains in the morning. Do with with Optimize Battery Charging enabled, and then again with it disabled, and let me know what you experience. Thanks.
