The modern smartphone is one of the greatest feats of human engineering. Just a few decades ago, to be able to do the things you could on a current-generation smartphone required quite an investment in desktop technology. Now, you can pick a perfectly capable phone up for less that it would take to gas up an SUV for a month. The fact remains, however, that it's essentially a pocket computer, and as such, is bound by the constraints a computer has, foremost being that relies on electricity. To add insult to injury, battery technology hasn't progressed nearly at the same rate the rest of the device.This is great for powerbank manufacturers, but for the rest of us, it blows. You'll be lucky to get an honest day's worth of use from a mobile phone these days.
That is, unless you use the Asus Zenfone 3 Max.
