The battery's health naturally decreases over time as the device is used, but we can extend battery performance within a limited time frame by using the battery wisely and paying attention to usage habits to slow down aging.
What is Battery Health?
Battery Health is a measure of battery life, indicating the difference between the current maximum capacity of the battery and that of a brand-new battery. The better the battery’s health, the longer the battery will last on a single charge cycle. The worse the health, the shorter the usable time.
Why does the battery age?
As the device is used over time, battery health naturally decreases. This is due to the chemical properties of lithium-ion batteries and is an unavoidable phenomenon.
Battery health is related to your usage environment and habits. For instance, prolonged exposure to high temperatures, maintaining a full charge for extended periods, or frequently depleting the battery can all cause the battery to age faster.
Xiaomi's professional battery health management technology can effectively help slow down battery aging.
If your phone supports the Battery Health feature, please check the battery health.
To extend battery life and slow down battery aging, please refer to the following methods:
1. Avoid prolonged exposure to high temperatures:
The ideal temperature range for optimal battery performance is 15°C to 28°C. If the device is exposed to temperatures above 35°C for extended periods, battery aging will accelerate, and its performance will decrease;
2. Avoid using the battery in extremely low temperatures:
When using the device in temperatures below 0°C, the battery's usable time will temporarily shorten due to the battery's chemical characteristics at low temperatures. Once the temperature returns to normal, the usable battery time will also return to normal;
3. Avoid keeping the battery fully charged for long periods or frequently depleting the battery:
The optimal range for maintaining battery life is when the charge level is between 40% and 80%. Keeping the battery fully charged for long periods or frequently draining it will accelerate battery aging. It is recommended to unplug the charger once the battery is fully charged and recharge the battery when it is low to help slow down aging.
If your device supports this feature, please enable Smart charging protection by referring to the steps:
Go to [Settings] >> [ Battery] >> [Battery protection] >> [Optimized charging].
These suggestions are based on principles that can help extend battery life. Since the battery is a consumable item, it's advisable to adopt reasonable maintenance practices based on your actual usage.
