Podcast #51: Smartphone Battery – Not all mAh are Created Equal

Smartphones have become a big part of our daily lives. From advanced processing power to vivid high-refresh-rate displays and stunning cameras, there is a lot that modern smartphones offer. But whether you are at home, in office, or traveling, it is the battery that decides your smartphone’s ability to communicate, complete a transaction, or click photos at any given time.

Smartphone battery technology has evolved over the years. Smartphones now pack higher capacity batteries along with faster charging speeds and more. But when choosing a smartphone, the only available battery capacity information is the mAh (or milliamp hours) number, which is not enough. So, what are the other battery parameters that one should look for when buying a new smartphone?

In the latest episode of the ‘The Counterpoint Podcast’, host Peter Richardson is joined by special guest Olivier Simon, DXOMARK’s battery unit director. Olivier shares some insights on DXOMARK’s smartphone battery evaluation, factors that affect battery life, and more. Olivier further deep dives to explain what mAh and watt mean and how do they translate into the experience when it comes to smartphone battery life. He also has some tips for OEMs on how to design smartphones keeping the battery aspect in mind. For consumers too, he has some advice on how to buy a smartphone with a battery life that fits their needs.
