A non-removable 3000 mAh lithium-ion battery powers the OnePlus 3, delivering an endurance rating of 66 hours in performance tests. While not outstanding, the battery life is sufficient for an average day of use, aided by a power-efficient processor and the device's software optimizations. The support for 20W wired charging ensures that the phone can be recharged quickly, alleviating some concerns about running out of juice during a busy day.
