Does fast charging damage the battery? His two-year experiment with 40 mobile phones revealed the secret: just use and charge
But this brings a problem. Many people wonder if such a high speed charge will damage the battery and reduce its life?
Coincidentally, as a digital blogger who has been on CCTV, “Classmate He” finally released a new video last night. It took him 2 years and 40 cell phones to finally get the answer to this question. .
Let’s talk about the result first: you can charge the phone occasionally, and you don’t have to worry about damaging the battery at all!
Does fast charging damage the battery? His two-year experiment with 40 mobile phones revealed the secret: just use and charge
To put it simply, a student He conducted three charging experiments, and the first two failed. Last time, 10 iPhone 12s and 10 Androids were used for charging comparison The fast charging of the Android group was 120W.
They are divided into three groups, one uses slow charging, one uses fast charging, and the other uses the most well-known charging method: keep the power between 30%-80%, and charge charge when below 30. (quick charge), disconnect when above 80.
After running the test for more than half a year through the control algorithm written by me, the final result is as follows:
1. After 500 cycles, fast charging no longer damaged the battery.
2. Keeping the phone battery at 30% to 80% helps the battery, but the help is very limited.
3. If the mobile phone is connected to the charger without unplugging for a week, the battery capacity is basically not affected.
