So a big battery can make a big difference… Who knew?
The 3450 mAh battery is certainly a big selling point for the Nexus 6P—beefier than the 3220 mAh cell on the Moto Nexus 6 and not even in the same league as the 2700 mAh Nexus 5X. For our American readers, I’d say that battery size alone would justify the $70 USD premium over a 32GB 5X; for Canadians that same premium balloons to $140 CAD. It might still be worth it if you consider the 6P’s other charms.
To better illustrate the impact that a bigger battery can have let’s use my better half as a use case.
My girlfriend works in an office with a strict IT policy—no unauthorized devices are to be plugged in to work computers at any time. This, along with a lack of available power outlets, means that her phone’s battery has to last her through the entire work day. With a 2300 mAh 2013 Nexus 5 that was usually impossible. We started buying portable USB chargers for travelling, but they quickly became invaluable to keep her connected while at work.
Now, with a 3100 mAh battery powering the 1080p screen on her OnePlus One a dying phone is no longer a concern; she only takes a battery pack to work with her if she forgot to charge the night before.
For myself, a big enough battery means that I can leave the house with a 20% charge on a Nexus 6P and have no concerns about using it on a hour-long graffiti walk (as I did yesterday). Or, if I’m on vacation constantly taking photos and consulting Google Maps, I no longer have to worry about my phone lasting an entire day on a single charge.
TL;DR I’ve come to see battery life as the biggest shortcoming of the Nexus 5X, and so far the biggest virtue of the 6P.
