Smartphone batteries have naturally increased in size over the years, but for the most part most are still hovering around the 3,000mAh range. This is where Huawei attempts to differentiate themselves with the Mate 10 series in which the company confirmed that the phones would pack a 4,000mAh battery.
However the problem with a bigger battery is that it could potentially take longer to charge to full than a smaller battery, even with fast charging, but it seems that isn’t necessarily the case. According to a test conducted by Phandroid, it seems that the Mate 10 Pro’s 4,000mAh battery took 1 hour 20 minutes to charge from 0-100%.
Phandroid’s Chris Chavez notes that this is generally the speeds that we can expect from fast charging technology today, but what sets the Huawei Mate 10 apart from the competition is that despite it packing a larger battery, it still took the same amount of time. Chavez cites the OnePlus 5T’s charging time as being around the same, but with it featuring a smaller 3,300mAh battery.
He also points out how the Pixel 2 XL took considerably longer at 2 hours 43 minutes, and the Note 8 which took 1 hour 47 minutes. Of course this does not mean that the other phones are “worse”, but if you’re someone who’s on the move often and who does not have a lot of time to sit around and wait for their phones to charge, then the Mate 10/Mate 10 Pro’s charging speeds could be an aspect to consider.
