watchOS 9 leads among us in the form of beta a couple of weeks. Apple has decided to invest time in developing useful tools for users in this new update. Among those options is greater accuracy when calculating battery life through a recalibration in the Apple Watch Series 4 and 5, which are added to the already existing option in the Series 6 and 7. Apparently, a battery saving mode is hidden in the code of watchOS 9 similar to the one available in iOS and iPadOS that It could arrive with the Apple Watch Series 8 and it would be an exclusive function at the hardware level.
watchOS 9 battery saving mode would be limited by hardware
Rumors pointed before WWDC22 to a new more efficient watchOS 9. The integration of a new battery saving mode. This mode was similar to the one available in iOS and iPadOS, a tool to limit the options of the operating system, guaranteeing the usability of basic functions while conserving the maximum possible battery.
Remember that this potential battery saving mode must be differentiated from the low power mode. This last mode is activated when the watch drops below 10% battery guaranteeing that the clock will strike the hour, but the rest of the options are disabled, there is no access to any option related to watchOS beyond the time.
However, Apple didn't include battery saver mode in early betas of watchOS 9. Now the analyst Gurman ensures the saving mode will arrive with the Apple Watch Series 8. Therefore, it would be an exclusive option at the hardware level, leaving the rest of the models behind, leaving only the new watches that will appear in the coming months compatible with this mode.
