1. Charge for 2-3 hours after the first three full charges, and then use it after each full chargeNote: Do not charge the battery after the power is completely exhausted, it will affect the battery life.

2. Do not use the mobile phone for a long time during the charging process, please wait for the charging to be completed before using and operating the mobile phone.

Here are a few tips for using your phone's battery:

1. Do not over-discharge. When the device prompts "low battery", it should be charged; Charging is not until the device is automatically turned off, and the battery has been over-discharged. This can affect battery life.

2. Do not overcharge. When the charger gives a full charge, it should be unplugged. Now the charger generally has a full self-stop design, it doesn't hurt to take off the battery from the charger for a short time, but leave the battery on the charger for a long time, and the grid voltage rises in the middle of the night, and the charger that has stopped charging will continue to charge after the voltage rises, causing the battery to overcharge.

This can affect battery life.

Now it's all lithium batteries, don't charge them for 12 hours, just charge them.
