It used to be the case that fast charging a flagship Android phone would have a notable effect on long-term battery health. I could personally attest to this with my old HUAWEI Mate 20 Pro, as several years of 40W charging resulted in a significant drop in battery life.

One way to measure the effect of fast charging on a smartphone is to check the device’s peak and average temperatures while plugged in. Colleague Rob Triggs did just this and found that the OnePlus 13, OPPO Find X8 Pro, and Samsung Galaxy S25 Ultra all boasted cool temperatures while charging. We also posted a poll asking whether you’re still concerned about the long-term effect of fast charging a phone’s battery.
