Apple’s low power mode isn’t just for the new watches
When Apple announced the Apple Watch Series 8 on Wednesday, it introduced a new low power mode feature that lets the wearable double its battery life by turning off a few features. It won’t be limited to Apple’s latest devices, though — during the presentation, Apple said low power mode is coming to “the Series 4 and later” with watchOS 9, which is launching September 12th.
The company didn’t say whether the mode would be as effective on older devices as it claims it will be on the Series 8 and Apple Watch Ultra (Apple says its bigger watch will be able to go from 36 hours of runtime to 60 with the mode turned on). But based on what we know about how it works, it’s clear that it’ll be less effective on at least a few models.
