Reason 1: The phone battery is depleted and it shuts down.

Solution: At this time, it may not be possible to charge it directly by plugging it into the mobile phone, and you need to use a universal charge and deduct the battery to charge.

Reason 2: The mobile phone battery is virtual (the battery is damaged), the so-called virtual power is that it is still charged on the mobile phone, but in fact, there is no power in the battery, so many times it turns off when there is one or two squares left.

Solution: Replace a new original battery or a good domestic brand battery.

Reason 3: The mobile phone battery is not in good contact with the metal contact point of the mobile phone, or the back cover is too loose.

Solution: Wipe the metal contact points and put some sponge or something behind it.

Generally speaking, it is a system problem or a battery problem, it is possible that the battery has been dropped, try to change it, and you can also use the original one.

My Samsung 5830 has been used for a year It was also this problem before You can open the back cover and pull down the battery with your hand to see if the phone is turned off Most mobile phones have this problem After a long time, it is a little loose I pad a piece of transparent glue.
