Samsung phones don t have a charger and what else can be charged

At present, Samsung mobile phones on the market use lithium batteries, and the battery has been activated when it leaves the factory, and the lithium battery has no memory, so it can be charged at any time. When the battery is fully charged, it can be powered off (after the first three full charges, it can be charged for another 1-2 hours). Here are a few tips for charging your phone:

1.Do not over-discharge. Wait for the device prompt"The battery is low"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. So when the phone prompts that the battery is low, it can be charged. 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. 3.If the battery is not used for a long time, it should be charged to 60%, stored separately in a cool and dry place, and recharged every other month.

4.It is recommended not to use the mobile phone when charging, and it is on standby for charging.
