The latest version of iOS 26 includes a complete revamp of the low power mode system. The ‘new’ low power mode is more efficient in power saving than what we had in iOS 18. It considerably reduces the frames in UI, applications to save on battery. So, you can expect a lot of fps drops, stutters during the low battery mode in iOS 26. The iPhone automatically caps the refresh rate to 60 Hz in low power mode, even in the iPhone Pro models. This sudden reduction may appear to be stuttering, as you are too used to the 120 Hz refresh rate.
This also includes 5G connectivity in low power mode, which is completely disabled on several iPhone models. The animations in UI also slows in the new iteration of Low Power mode. So, the device may feel choppy and laggy.
