Lenovo K910 mobile phone charging is slow, what is wrong with fast power loss

Hello, thank you for choosing Lenovo products, and I'm sorry for the inconvenience caused to you in the process of using it.

2.Whether you use it for a long time, using large apps or making calls for a long time will consume a lot of power, it is recommended that you adjust the screen brightness appropriately;

3.It is recommended that you close the system background programs regularly, or you can use the "Phone Acceleration" function in Le'an.

4.It is recommended that you use Le to save electricity, this is a power-saving and energy-saving software officially launched by Lenovo, you can go to the Le store to search**, and Bluetooth, GPS and other functions are recommended to turn off energy saving when not in use.

If the power consumption is still serious after the above operations, it is recommended that you back up the body data for factory reset operation and resume observation, if the problem still exists, please take the time to go to the Lenovo site for specific detection and processing.

1. Please use the original charger and data cable for charging, if it is the original accessories for charging, you can replace other data cables if possible, in order to rule out the abnormal accessories;

2. It is recommended that you try to change the charging environment, and it is best to use the power supply for charging to avoid unstable voltage and current;

3. If you are powering on the phone for charging, please close the background program or restart the device for comparison, it is not excluded that the background program will consume more power;

4. It is recommended that you compare the charging in the standby state or the shutdown state to avoid charging the model while operating, which will generate the corresponding power consumption during operation, so as to prolong the charging time;

5. It is recommended that you back up the fuselage data and try to restore factory settings to rule out the impact of system abnormalities.

If it cannot be improved after resuming operations, it is recommended that you go to the local site for specific testing and treatment in time.

There are several common reasons why the phone cannot be charged or is not successfully charged:

1. Use non-standard chargers;

2. Charging circuit failure;

3. You can try the following operation when the battery is aging

1. If you try to charge with the newly replaced standard electrical appliances and data in the shutdown state, see if it can be fully charged, if there is sometimes a full and sometimes not full in the shutdown and on state, please check whether the battery connector and the battery have loose contact. It is recommended to reseat the data cable, the charging head, and the connection part of the mobile phone.

2. If the power is turned off and charged normally, the boot state cannot be fully charged, please verify whether the machine has done other operations during charging, such as calling electricity, listening to songs, surfing the Internet, etc., whether there are multiple applications running in the background, which will consume power; If there is no power consumption operation running in the background but it cannot be charged, it is recommended that you back up the data, restore the factory settings, temporarily install the software, and try again.

3. If you try to operate, it is recommended to bring the warranty card or invoice to the local maintenance site to reflash the system, and check the authorized maintenance site on the official website of the relevant hardware.

For more than 2 hours, it is as full as when it is turned off and charged.

We apologize for any inconvenience this may cause.

We're sorry for the confusion. When charging, in addition to the heat generated by the normal system operation of the device itself, there is also heat generated by electric energy conversion during the charging process, so it is normal for the temperature to be higher than that in the non-charging state. For high temperatures during charging, please refer to the following suggestions:

1. Confirm whether to use the standard charger for charging, if not, please replace it. Frequent use of non-standard electrical appliances is not conducive to the maintenance of mobile phone batteries and will reduce the life of the battery;

2. Verify whether to use the mobile phone while charging, there are more hardware-related components involved in charging, and more processes are called, in order to ensure a good user experience, the CPU will work at full load, so the power consumption is larger, and the heat generation cannot be avoided. If you operate while charging, you will consume electricity, which in turn will generate heat and prolong the charging time. Using it while charging is also not conducive to battery maintenance, and we do not recommend users to do so.

If there is no excessive operation and the temperature of the device reaches the level of hot hands during charging, you can turn off the device first and contact the nearby Lenovo after-sales service site for testing and maintenance, so as not to affect the subsequent normal use.
