I had 30% battery, it dropped to zero in an hour is it normal? I'm afraid to use the phone and I did everything restart, factory settings, safe mode, it's bad, after the last update it's even worse, I have a camera in my nose, fix the battery optimization , runs out incredibly fast, now 30%, after posting 19%, four minutes, shock and scandal, phone 8 giga on 256, and ordinary toy I regret all the money I spent, and still pure android, where your flagship zenui cover? another phone from every company stays with its cover, only you, I'm angry at myself that I trusted Asus, my old asus 2 is better to use than the flagship asus 6
