Pick a device with the best phone battery life, and you’ll never need to worry about having to find a place to recharge your handset ever again. And fortunately, there are a lot of phones out there today that can deliver when they promise you all day battery life, whether you’re considering a high-priced flagship or a budget phone.

Because a phone’s longevity is so important to shoppers, phone makers are turning to increasing bigger power packs to keep their devices up and running. Phones from Samsung, Xiaomi and Motorola feature massive 5,000 mAh batteries, offering the promise of handsets that can go all day — and beyond — on a single charge. But, as we’ve found in testing phones, there’s more to landing on our best phone battery life list than offering up a bigger battery.
