Our expert testers put more than 75 smartphones through their paces to give you accurate information about battery life, as well as factors such as durability and GPS performance, which are important when you’re cut off from the world but need to stay connected.

Quick-charge champions

Why is it that you only realise your phone is about to run out of battery just as you’re leaving the house? A mobile power bank is a good option in these situations. But if you don’t have one, quick-charging technology could save you. 

“This is where the phone is able to take a big hit of energy to increase the battery capacity in less time than usual,” says Denis Gallagher, CHOICE smartphone expert. 

“Some phones can give you several hours of use from just a 15-minute charge before you dash out the door. 

“The lesson here is: check out your existing phone to see if it supports quick charging, and you could give it a new lease of life by buying a quick charger for those times when you need to charge in a hurry.”
