Battery & Charger

Continuing the one major feature that defined the ZenFone Max series is the humongous battery. ASUS is continuing the trend by including a 5,000mAh battery inside the ZenFone Max Pro (M1) – the largest and most overkill battery for a smartphone ever. Personally speaking, we’ve been spoiled by the ZenFone 3 Zoom’s power efficiency combined with a 5,000mAh. I never had to charge the phone for 2 days and I still don’t have to charge it.

With that said, here is the battery life test result for the ASUS ZenFone Max Pro (M1).

With the efficiency of Qualcomm’s Snapdragon 636 chipset, the battery life can be extended and defeat the Zoom by a long shot.


I think it’s a common feat now where ASUS is just including the same charger for all of its smartphones. I mean, ASUS has been using this exact same 5V 2A charger since the ZenFone 3 series – with a few phones having a black colored charger instead of white.

It took me long enough to drain the battery – and in less than 3 hours, the battery was charged from 15% to 100%! Take a look at the charging graph here.

It took about 50 minutes to charge from 15% to 50%, and an hour and a half to charge from 15% to 75%. After that when the charging curve starts to plateau, it takes a total of 2 hours and 42 minutes to charge from 15% to 100%. Learn more about the charging curves here.

For those who are charging your phone while you sleep, then the total charge time of 2 hours and 42 minutes isn’t a big deal at all. Once you wake up, you have the ZenFone Max Pro (M1) fully charged up and ready to last for a total of 2 days of usage. Two daysOne charge. It’s just insane.
