Whatever else you want to say about the OnePlus 12 series of phones — and we've had lots of praise, as you can see in our OnePlus 12 review — you'd have to concede that OnePlus absolutely delivered on battery life with its latest phones.
Take the aforementioned OnePlus 12. That $799 phone features a 5,400 mAh battery and a power-efficient Snapdragon 8 Gen 3 chipset, and it took advantage of both to turn in a time of 17 hours and 41 minutes on our battery test. That's almost an hour longer than the Galaxy S24 Ultra, a phone that costs $500 more than OnePlus' latest handset.
