Significant changes in the battery power of mobile phones are mainly caused by the following two situations:
① Due to the influence of ambient temperature, if the ambient temperature If the current use of the machine is too low, the battery power will drop to varying degrees, resulting in an increase in the battery level, and the mobile phone may even turn off automatically. This is a common occurrence. The mobile phone will resume use after returning to normal temperature. Please feel free to use it.
② If the machine has just been turned on, low. This phenomenon occurs when the battery is low or has not been used for a long time. Don't worry. will automatically calibrate the battery. During the calibration process, the battery display will be adjusted to a certain extent. It is recommended to use the mobile phonee normally (load and unload several times) before checking.
If you use vivo mobile phone, you can refer to the following treatment methods:
1).? If the temperature is too low
① It is recommended to keep it between 0℃ and 35℃. When you use a mobile phone in too low or too high an ambient temperature, it may affect the use of the mobile phone and even damage the battery and the mobile phone. Here are some practical suggestions:
② Put your phone in your pocket and try not to expose it to cold outside air;
③ Put a protective silicone case on your phone. cell phone from contact with cold air;
④ If you listen to music or make a phone call, try to use headphones to avoid contact with the low body temperature of the mobile phone
;⑤ In case of emergency If you turn off aaccidentally your phone due to freezing, warm it up in a warm environment and turn it back on, and it will be "resurrected".
2). If the phone has just been turned on, the battery is low, or it has not been used for a long time
It is recommended to use the phone normally and use the charger and cable original data to perform one/several complete cycles. Charge (use the battery to about 20%, then charge it fully) before using;

What is the “dead power” phenomenon of cell phone lithium batteries?
The battery charging time does not can't be very long. Battery activity. a battery charged for a long time will weaken quickly.
Once the battery is exhausted, it cannot be stored without being charged. This will easily cause the battery's lithium ions to lose activity. The lower limit of the voltage of each cell of the lithium battery is 1.0. Volts. If the voltage is lower than this, the battery will not be charged. Long-term storage of electricity will make the battery incapable of being recharged. This may explain why a discharged battery cannot be recharged after a long time.
Once the battery is fully charged, it cannot be left unused for a long time. Used batteries should be fully charged and discharged (used) every one to two months. Otherwise, the activity of lithium ions in the battery will be weakened, which will affect the battery capacity. This may explain why some batteries have shorter charge and discharge times when reused afterhave been left for a long period of time.
Detailed information:
1. Charge it only after it is completely exhausted
Many people have the habit of fully recharging their cell phone or power bank after they are completely exhausted. completely exhausted. However, the truth is that it can damage the equipment.
When the power is too low, the activity of the lithium battery will decrease. If the power is completely exhausted frequently, the battery capacity will decrease, so it is better not to use the power bank after the last time. the charge is exhausted. The same goes for mobile phones before charging. When the battery level is below 15%, it is a good time to charge.
2. Pay attention to the temperaturere ambient
The most suitable operating temperature for lithium batteries is 0 to 55°C. When the outside temperature is too low, the battery will work unstable. and the discharge will be insufficient; high temperature will shorten the life of the battery and circuit board, damage the battery, and cause some components to age. Overall, the power bank is also a “delicate” product that fears cold and heat.
If you are using a vivo phone and there is a problem with virtual power:
1. If you use a non-original charger, please replace it with this one. original charger;
2. Enter settings - system upgrade. Some iQOO (Monster) UI/Funtouch OS9.2 version models need to enter settings - My Device - iQOO (Monster) UI/Funtouch OS version. version, detect and update the system;
3. Perform afull charge cycle (use the battery to about 20%, then charge it fully), calibrate the battery before use;
4. Enter phone settings - System management/More settings - Backup and reset/Restore factory settings - Restore all settings/Erase all data (Please backup important data on your phone before this operation);
If the above method cannot solve the problem, it is recommended to take your mobile phone to the local vivo customer service center for inspection and treatment, enter the vivo official website/vivo mall APP - My - branch query, select your current city to get the address and *** from the customer service center. Warm reminder: In order to save valuable time, it is recommended to contact the customer service center by telephone to confirm working hours before leaving.
