The more the phone is charged, the less power can be caused by a variety of reasons:
charging head or data cable problems. If the charging head or data cable is not plugged in, or has been worn and aging, it may lead to reduced charging efficiency, or even can not be charged normally.
Problems with the charging environment. If the charging environment temperature is too high or too low, it may affect the charging efficiency of the battery, resulting in a decrease in power rather than an increase.
Cell phone battery problem. If the phone battery is old or damaged, it may also affect the charging efficiency. If the mobile phone battery has been overcharged and discharged, it may lead to a decrease in battery performance, resulting in a decrease in power.
The phone runs a lot of power-consuming programs during the charging process, resulting in the phone consuming more power than the charge.
If you want to solve this problem, you can try to replace the original or genuine charger and data cable, avoid using poor quality or incompatible charging equipment. At the same time, check the phone battery is abnormal, if necessary, replace the battery. In addition, close or uninstall unnecessary background programs to reduce the power consumption of the phone. Keep your phone charged within the appropriate temperature range and avoid charging in hot or cold environments. If the above methods are ineffective, it is recommended that you back up your data and carry your mobile phone, charger, data cable and purchase voucher to the nearby mobile phone after-sales service center for testing and maintenance.
There may be the following reasons for the decreasing battery charge:
charger or data cable failure. This may result in unstable or insufficient output current due to damage, aging, or quality issues.
The mobile phone battery is faulty or aging. The battery itself may have faults such as short circuit and expansion, which will cause the battery to be unable to charge or store power normally. At the same time, with the growth of mobile phone use time, battery aging will also lead to a decrease in battery capacity, lower charging efficiency, and even leakage phenomenon.
The phone runs a lot of power-consuming programs during the charging process, such as games, video playback, etc., which makes the phone consume more power than the charge. The high temperature environment may also have a negative impact on the charging effect of the phone, the battery may be slow to charge, or the charger may not provide enough power. Software updates can sometimes cause the phone to charge less effectively, as the new software version may drain the battery power faster or affect the charging speed.
Please note that there may be other reasons why the phone cannot be charged, such as hardware failure. If the phone is not charged, it is recommended to consult professional maintenance personnel.
