3 Common charging errors and how to avoid them
Incorrect charging is the main cause of premature battery wear, and here are the typical Xiaomi user errors and their consequences:
- π₯ Using uncertified cables β cheap unprotected cables can cause overheating or even short circuits, especially dangerous for fast-charging models.
- βοΈ Charging at extreme temperatures β if the case is cold (below) +5Β°C) or hot (above) +35Β°C), the battery loses capacity on 10-15% cycle.
- π Storage of discharged headphones β if you leave the headphones in a discharged case for a month, the battery can fail.
- π Constant connection to power - keeping the case on the charge "in reserve" reduces the battery life on the 20-30%.
β οΈ Warning: If one earphone discharges faster than the other after charging, check the contacts in the case for oxidation or debris. 80% of the time, the problem is solved by cleaning with an alcohol wipe. If the difference in discharge persists, this is a sign of a malfunction of the battery in the earphone.
