Does fast charging damage the battery? Two-year experiment with 40 cell phones revealed the secret: just use and charge
Last night, Redmi officially released the Note 12 Discovery Edition mobile phone, which debuted with Xiaomi’s self-developed 210W fast charging technology, surpassing the current limit of mass-produced mobile phones.
According to official data, the machine can fully charge the battery in 9 minutes, pulling the charging time into a single digit for the first time.
But this brings a problem,Many people wonder if such a high quick charge will damage the battery and shorten 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 your phone randomly and you don’t have to worry about damaging the battery!
To put it simply, the student conducted three reload experiments and the first two failed. Last time, 10 iPhone 12 and 10 Android 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% and 80% and charge when it is below 30. ( fast charging), disconnect if higher than 80.
After running the test for more than six months through the control algorithm written by me, the final result is the following:
1. After 500 cycles, fast charging no longer damaged the battery.
2. Keeping the phone battery between 30% and 80% helps the battery, but the help is very limited.
3. If the mobile phone is connected to the charger without disconnecting it for a week, the battery capacity is substantially unaffected.
4. When the iPhone battery health drops to 85%, replacing the battery can greatly improve the user experience.
