Many people find that after using the mobile phone for a period of time, the mobile phone battery is not charged, or it needs to be charged for a long time. There are many people who may feel that their batteries will not be fake, in fact, this argument is not all right, the real battery will sometimes appear in this situation.
The mobile phone battery charge is mostly the problem of the mobile phone itself, it is likely that the mobile phone itself has some deviation in the detection of voltage, the mobile phone has been fully charged when it can not make the correct judgment, but also that the power is 70 to 80%. As long as you press the button *#*#4636#*#* when charging, look at the voltage of the battery, you know, the voltage may already be 4201mV. Restart your phone, and immediately it's 100% charged.
Sometimes the phone battery charge may also be dissatisfied with the software problem, this time you can install some software to correct it.
If the Samsung phone cannot be fully charged, it is recommended that:
1. Check whether the original charger is used. If not, please replace the original charger and try again.
2. Replace another power socket.
3. If the battery supports removal, reinstall the battery or replace it with another original battery and charge it again.
4. Update the mobile system version: Settings - About the phone (about the device) - manual download update\/automatic download update (software update\/system update - update). Note: Back up the data on the device before the upgrade. If the above operation is invalid, please bring the purchase invoice, repair card and machine to the nearest service center for inspection
