I was reading The Verge's review of the Moto Z Play, Lenovo's latest phone in the Moto line, and got this this bit about how the phone was able to achieve such impressive battery life:
Lenovo found an approach that allowed the company to make a phone you can charge up overnight, unplug the next morning, and use for two days straight. No asterisks. No buts. It’s been such a refreshing thing to experience over the few weeks I’ve spent with the Moto Z Play. And it turns out the formula is pretty simple! You combine a big battery, a new, mid-range Qualcomm processor that slowly sips power, and then “settle” for a 1080p screen and 3GB of RAM.
Of note, the screen on the iPhone 7 Plus is also a 5.5 inch 1080p display1. And just like the Moto Z Play, the iPhone 7 Plus gets ridiculously good battery life as well. The screens on the iPhones are great, even if the exact resolution gets some tech critics worked up. The screens are great, and they are a major reason the iPhone is able to get better battery life than most Android phones out there, so I'd say it's a solid trade off.
Of course the iPhone screens will eventually get higher resolution screens, but there is so much they can improve that users will actually appreciate before moving onto the screen.
- And 3GB of RAM as well, for what it's worth. ↩
