No update or patch to fix the issue after March 2019. This battery draining issue after Android Oreo 8 update, Samsung Galaxy J7 Max, moreover reluctance towards consumer is compelling me to shift into another brand, using Samsung since 9 years, losing faith and trust after being a loyal customer, dissapointed. It is time to go for other brand, really the trust and faith is lost in the wave of better Companies. The resolutions from technical support is mind blowing, a scripted guide of setting up battery optimized modes, although I am not a heavy user, my primary task is neither heavy like gaming, the idle and android system is consuming extra charge and screen on time has decreased. A moderate 2 hours average usage, a 15 month old device. Thank you for everything Samsung. Dissapointed.
J7 Max will never get Pie update. Please refer the last list for the upgrade which has just two devices. J7 Max has never been in Samsung's radar right from the beginning. They never divulged it. Its purchase turned out to be bad bet. Samsung completely neglected the J7 Max buyers. Overall its profit from the device is more than other similarly priced ones.
