Among all of the things that people debate on when making a comparison between smartphones, there is always one single thing that renders others useless. 

 

Most of the times, every single phone comparison ends with the question, “how good is the battery life?”

 

In case your phone runs out of the battery pretty quickly, there is no point of having the other amazing features after all. Hence, bad battery life is something that most of the people cannot really tolerate smartphones. 

 

The iPhone is considered to be one of the few devices that need a significant improvement in battery life. This is one of the prime reasons why most people still choose to stick with the Android phones that offer a better battery life at a lower price. 

 

Probably, people have simply started to use their phones way too much. Where the small battery of a smartphone could only provide power up to a limit no matter how efficient it is made. 

 

An explanation of the battery capacity 

 

The capacity of the battery is measured in terms of milliamp hours (mAh). The higher the mAh of the battery is, the better its capacity would be. However, even many phones that have a higher battery capacity do not have higher battery life. 

 

The battery life on itself depends on a range of different factors such as the efficiency of the software and processor along with the personal usage time. Most of the expensive and higher-end phones happen to be faster with better screens, but this also means that the battery life can be really short. 

 

What to consider? 

 

Phones that carry some extremely good looking QHD displays are likely to drain the battery faster than the phones that have a low-resolution display. Hence, you will have to priorities in this case. Most of the times, the best battery life can be found on some of the mid-range phones. Fortunately enough, this also means that they will be relatively cheaper. 

 

On the other hand, the mid-range or cheaper phones do not have a very fast charging time. The latest phones in comparison, charge up pretty quickly, often taking only an hour and a half to go to 100%. Hence, this is another factor that you need to consider. 

 

What do our test results say? 

 

Based on our test results, the Huawei Mate 20 Pro takes the lead in being the best battery life phone in 2019. With a battery size of 4200 mAh, this phone actually delivers an amazing battery life while still providing plenty of high-end performance features. 

 

In comparison, the Moto E5 Plus has a battery size of 5000 mAh, which provides a larger battery time. However, it is not the best in terms of performance. Nevertheless, at a price point of around £179, you get a pretty solid phone. 

 

The Asus ZenFone Max Pro M1 stands the third in line. With its 5000 mAh battery, the phone delivers an amazing battery life. Since it performs better than the Moto E5, its battery life is relatively lesser. Nevertheless, it backs a balanced blend of battery life, solid build, dual camera, and acceptable performance all in one.
