Apple recently unveiled iOS 26 as a developer beta during WWDC 2025, captivating attention with its major Liquid Glass redesign. However, amidst the highlight, several features merit greater focus, including an intriguing new addition related to battery management. One notable feature is the estimated time to charge, a functionality that has long existed on Android devices.

Interestingly, brands like OPPO, OnePlus, and realme have begun to phase out this feature in their devices this year. Consequently, it’s anticipated that it may return with future updates such as Oxygen OS/Color OS 16. Additionally, iOS 26 introduces a new battery feature that hints at the forthcoming iPhone 17 Air: Adaptive Power.

According to Apple’s description, this feature is designed to make minor performance adjustments when battery usage is unusually high, such as reducing display brightness or extending certain tasks. Low Power Mode may also activate at 20% battery. This function bears a resemblance to Google’s Adaptive Battery feature on Android, aiming to optimize performance for longevity when the device is used heavily.

Given that the iPhone 17 Air is rumored to have a compact 2,800mAh battery, which is significantly lower than the 3,900mAh offered by the Samsung Galaxy S25 Edge, Adaptive Power appears to be an essential enhancement. At this stage, it remains unclear how assertively Adaptive Power will limit performance, as the feature is still in its early days. Apple’s forthcoming enhancements may refine this capability further.

Notably, the A18 Pro chip demonstrates impressive power, achieving over 3,500 in single-core Geekbench 6 scores, surpassing even the Snapdragon 8 Elite devices. With the iOS 26 release slated for September, several more beta versions are expected, allowing ample opportunities for evaluation and refinement of the Adaptive Power feature.
