Battery & Charger
With the Snapdragon 630 chipset and a 3,300mAh battery combined into a smartphone, I can foresee that its battery life will be great. And its battery life is considered okay, in my opinion. Sure, it’s not the longest lasting smartphone with a 3,300mAh battery out there – the Selfie Pro for some reason lasts a lot longer.
It truly boils down to software optimization at this stage. Honestly speaking, the new ZenUI has a lot of under the hood processes that might have slowly draining the battery in the background.
Seriously, I expect ASUS to be better than this. We still get the same old 5V 2A charger – the same one that is found on all the Max Plus (M1) too. I honestly expected a 9V 2A charger instead – a true Qualcomm QuickCharge 3.0 charger. But instead, we have this 5V 2A charger.
Here’s how long it took to charge the ASUS ZenFone 4 from about 14% battery to a full 100%.
It literally took about 2 hours to charge from about 14% to 100%! If ASUS would’ve just included Qualcomm QuickCharge 3.0 into the ZenFone 4, it would’ve shaved off about 45 minutes off the charging curve.
Though, you can reach about 50% at around 36 minutes, and 75% of battery at about the 1 hour mark.
