TOP 10 smartphones with best battery life

Battery life is one of the main problems of today’s smartphones. Sometimes its capacity isn’t enough even for a full day. We wonder producers that make devices with high-performance hardware and a battery’s capacity of 1600-1800 mAh. So we have selected best smartphones with the longest battery life.

A few words about battery life

Every phone has its lifetime that is depended on the battery’s capacity and phone’s power consumption. So phones with large screens and powerful processors need too much energy. Modern mobile phones (not smartphones) are equipped with battery’s capacity 800-1500 mAh. Some models with such batteries can work a few days, others weeks.

Situation with smartphones is much worse. Despite the fact that today’s smartphones are equipped with a battery capacity 1300-3000 mAh, their worktime usually limited to 1-2 days. So when choosing a smartphone you should pay attention to the devices with high-capacity batteries.
