In this ranking you can find those smartphones with the best battery life. Battery life is still one of the most important criteria when buying a phone. What is the use of a phone if you can use it only for half a day? With the smartphones listed in this ranking even power users can get at least 2 days of run time. Battery size (mAh) as well as software optimization are crucial for an excellent battery life. The top sellers also combine good performance with their huge battery.

Test of the smartphones with the best batteries:

The battery of a Chinese phone:

Smartphones from China house replaceable lithium-ion batteries. The battery life depends on the milliampere-hours (mAh). In general, you can apply the rule “the more mAh a smartphone has, the longer the battery life is”. Of course, display size and staying in areas with low reception decrease the battery life. If you have a compact smartphone up to 5 inches, a battery of 1800-2000mAh is sufficient. In the worst case you can use a second battery in order to double the battery life. Having a smartphone with a display bigger than 5.5 inches, the battery should be bigger than 2000mAh to secure the possibility of intense use for one day.

One advantage of the battery of Chinese smartphones is that you can easily replace the battery if it isn’t working anymore. If you possess an iPhone or certain smartphones by Samsung or HTC, you might have a problem if your battery is damaged: it means your entire smartphone is broken.

Most Chinese manufacturers already provide two batteries in the scope of delivery. If they don’t, you can easily order a second battery for about 5-10$.
