4. Improper storage of mobile phones.
With the development of the industry, mobile phones are being updated faster and faster. Many people have multiple mobile phones. The storage of dusty equipment should be stored as follows:
When storing for a long time, please keep half the battery.
If the device is not used for a long time, there are two key factors that will affect the overall operating condition of the battery: the ambient temperature and the percentage of the battery charged before being stored in a power failure. Therefore, the recommendations are as follows:
Do not fully charge or fully discharge, the device charge should be about 50%. If you store the device when the battery is completely depleted, the battery may fall into a deep discharge state, causing the consequence that it cannot be recharged. On the contrary, if you store a fully charged device for a long period of time, you may lose part of the battery capacity, thereby shortening the battery life.
Turn off the power to the device to avoid additional battery usage.
Place the device in a cool, non-humid environment, with a temperature below 32°C (90°F).
If you plan to store the device for more than six months, you should charge the device to 50% power every six months.
Depending on the length of time the device has been stored, a device that has been stored for a long time may be in a low battery state when it is used again. To use it again, you may need to charge it with the original power adapter for 20 minutes.
