Every smartphone users know the dilemma: It doesn’t matter how great your latest-generation smartphone is or which cutting-edge features it contains – the device still runs on old-fashioned electricity it draws from its batteries, often the weakest part of the phone.
10 Smartphones with the Longest-Lasting Batteries
With the number of apps people use, and the time they spend on their smartphones is increasing. Battery woes are all too common – the prevalence of power banks and charging stations popping up in different places certainly tell that story.
Some smartphone makers have tried to remedy this issue by bringing phones with really big batteries to the market. According to a phone comparison website, Phone Arena, the ASUS ROG II phone has the largest battery to-date with a 6,000 milliampere hours (mAh), followed by the Xiaomi Mi Max 2 with 5,300mAh.
Phone Arena measures battery life by running a custom web-script designed to replicate the power consumption of typical real-life usage. All devices that go through the test have their displays set at 200-nit brightness.
Here is the test result1:
| Smartphone | Battery use duration | Battery capacity |
|---|---|---|
| Motorola Moto G7 Power | 20h 8 min | 5,000 |
| Xiaomi Mi Max 2 | 17h 22 min | 5,300 |
| LG X Power | 15h 18 min | 4,100 |
| Motorola Moto E5 Plus | 15h 8 min | 5,000 |
| BLU Studio Energy | 14h 53 min | 5,000 |
| Huawei Mate 20 | 14h 26 min | 4,000 |
| Asus ROG Phone II | 14h 11 min | 6,000 |
| Motorola Moto Z Play Droid | 13h 43 min | 3,500 |
| Xiaomi Redmi 3S | 13h 39 min | 4,100 |
| Apple iPhone 11 | 13h 29 min | 3,110 |
In this test, the Motorola Moto G7 Power lived up to its name by lasting more than 20 hours on its battery. The aforementioned Xiaomi Mi Max 2 placed second with a use time of almost 17.5 hours, ahead of the LG X Power, whose battery lasted more than 15 hours.

But milliampere-hours alone do not determine how long a phone battery will actually last. Display size, resolution and how efficiently a device uses power play a role too. Recently, an Apple product has made it onto the list. The iPhone 11 was tested to last almost 13 hours and 30 minutes, therefore using its 3,110 mAh battery quite efficiently.

Footnotes
- This chart uses data from Phone Arena, which tests phones using a custom web script that mimics real-life use at a screen brightness rate of 200 nit (luminance). These use durations are well below those that phone manufacturers use to market their phones and also below those measured in continuous use (e.g. playing a really long video).
