One UI 5.1 complaints stack up with bugs and battery life concerns for older devices
Samsung recently began distributing One UI 5.1 for older smartphones. Initially, the OS update arrived without warning; Samsung eventually announced what changes it had made from One UI 5.0, though. In short, Samsung presented One UI 5.1 alongside the Galaxy S23 series, which are currently the only devices that ship with the new OS. However, the Galaxy S20, Galaxy S21 and Galaxy S22 series have already received One UI 5.1, as have the Galaxy Z Flip4 and Galaxy Z Fold4.
Unfortunately, the software experience has been inconsistent for some and not necessarily as smooth as it is on the Galaxy S23 series. According to 9to5Google, complaints are on the rise of various issues experienced having upgraded from One UI 5.0 to One UI 5.1. Supposedly, devices like the Galaxy S22 Ultra have noticeably shorter battery life running One UI 5.1 than its predecessor or earlier versions of One UI. Also, there are other reports of increased temperatures, although this may be because One UI 5.1 automatically activates maximum performance mode.
Moreover, other users have reported problems with Bixby routines, the Samsung Keyboard, Colour Palette and even a device name. Presumably, Samsung will address these issues with future patches, which it tends to release monthly. Currently, it may be wise to wait on One UI 5.0 until Samsung has resolved any outstanding bugs.
