Many smartphone users will find that when you use a mobile phone for more than two years, the charging of the mobile phone will appear less and less or the battery's power display is incorrect. So, now let me explore what is the reason for the less and less the mobile machine?
Mobile phone charge less and less how to go
1, the output voltage is insufficient
The output voltage and power of computer charging can not reach the standard charging voltage and power, and the result is that the more and less it is charged, and it will also have a certain impact on the mobile phone hardware; Do not use cheap branded chargers, such chargers cost limited protection circuit is not perfect easy to cause overcharging and bad battery, try to use the original charger of the mobile phone;
2. Battery aging failure capacity decreases
Now is generally the use of lithium batteries, lithium battery itself has a certain service life, lithium battery life is mainly to charge and discharge times, normal use of up to 500 times or so, with the increase in the number of capacity is also proportional to the decline, if the battery aging affects the normal use of recommended timely replacement of the battery;
3, mobile phone tail plug aging and other reasons caused by poor contact; First, clean the tail socket of the phone with a cotton ball, and then try to charge it;
4, may be due to the mobile phone system software failure to accurately identify the current charging state of the phone, the actual battery has been full, but the battery power display is not charged, you can restart the phone and then try to charge;
The above is the reason and solution of the mobile phone charge less and less, I hope to help you!
Mobile phone charging to about 90 is not charged, can not rush in, because the mobile phone battery has memory, one way is to completely discharge, use the phone to shut down, and then full, so repeat three times you can reactivate the battery.
Another way is to use the battery optimization that comes with the phone to optimize the battery, which can also restore the performance of the battery.
The third way is the problem of the mobile phone system, you can restore the factory Settings, this method needs to back up your mobile phone's data and software to avoid loss.
Answer the first. You can directly shut down and restart, equivalent to data refresh, the general power display will return to normal.
2. Check whether the original charger is used
If the original charger is not used, it is recommended to replace the original charger. The power of the charger may be low
If the original charger is used, you can try to replace another charger to charge to see if it can be charged
3, the charger is in poor contact
Check whether the charger and socket contact is good, if necessary, you can replace the socket,
Check whether there are foreign objects in the charging interface of the mobile phone, resulting in poor contact of the charging interface, you can wipe the interface clean.
4. The charging ambient temperature is too high or too low
The phone is above or below a specific temperature value. There may be a failure to charge,
If the temperature is low, it is recommended to charge the phone in a slightly higher temperature environment, or use it for a period of time before charging
If the temperature is high, it is recommended to put the phone in a slightly lower temperature environment for a period of time before charging.

1. It is recommended to activate the battery while charging in the future, so that the battery will have no memory of charging.
2. Use the AC socket to charge, charge to 100% power off, and then charge to the green light in shutdown mode.
3. Boot into the recover mode, select advancsd advanced mode, and select wipe Battery to remove battery traces.
4. Power up to 100% so your battery has no memory and will charge much faster later.
If you turn off and charge, the mobile phone screen always shows a grid is not full, although the charging icon has been displayed in charging, but in fact, the phone power is 100%, you know when you turn on, in fact, it is full.
This may be a problem with the shutdown charging LOGO, and users who experience this problem can wait for the new firmware upgrade.
Or if you are not assured, send the phone to the after-sales inspection to see if the charging is not satisfied with the hardware fault of the phone itself.
