New update for the Asus Zenfone 3 Max makes its 4,100 mAh battery even better6
Perhaps the most notable feature coming with the patch (version 126.96.36.199) is the addition of ASUS Power Master, a new battery saving app, which will improve the time between charges for the already impressive 4,100 mAh power cell on the device. The update also contains optimizations for the touch panel display, camera, and fingerprint sensor of the Zenfone 3 Max.
Finally, the PLMN ID list and LED notification effects (while charging) have been updated, while a “customer service call issue in Italy” has also been resolved.
It might take up to a week for the patch notification to pop up on your screen, so if you wish to update manually now, you can do so by going to Settings → About → System update.
