Here are some ways to determine the degree of wear and tear on your phone's battery:
Use built-in phone functions
- Check battery health Many smartphones have built-in battery health monitoring functions. For example, Apple phones can check the maximum battery capacity in "Settings"-"Battery"-"Battery Health". This value directly reflects the battery's wear and tear; 100% indicates a brand-new battery, and a lower value indicates greater battery wear. Android phones from brands like Huawei and Xiaomi have similar functions, generally found in battery-related options in the settings or in apps like phone managers.
Observe usage
- Battery life If, under normal use, your phone's battery life is significantly shorter—for example, if it used to last a day on a full charge but now only lasts half a day or less—this indicates that the battery may have some degree of wear and tear.
- Charging speed Battery wear can cause slower charging speeds and excessive heat generation during charging. If your phone's charging time is significantly longer than before, or if it generates excessive heat during charging, this may also indicate battery wear.
- Automatic shutdown If your phone automatically shuts down before the battery is completely depleted, this may be due to battery aging, causing inaccurate battery level readings and the actual battery level being insufficient to maintain normal phone operation.
Use professional software
- Android phones You can install professional battery detection software such as AccuBattery to view detailed battery information, including battery capacity, charging speed, and discharge curves, to more accurately determine the degree of battery wear.
- Apple phones Use software like iBackupBot to analyze battery information in your phone's backup files to understand relevant battery data and judge the battery's health.
Go to a professional repair shop for testing
- You can take your phone to an official after-sales service center or a professional mobile phone repair shop. Technicians usually use professional battery testing equipment, such as battery testers, to conduct a comprehensive test of the battery, accurately determining key parameters such as battery wear and internal resistance, to more precisely determine whether the battery needs to be replaced.

What is the working principle of a lithium battery?
A lithium-ion battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. Its working principle is mainly based on the intercalation and deintercalation process of lithium ions between the positive and negative electrodes.
A mobile phone battery is an energy storage device that provides power to the mobile phone.
Battery capacity is usually measured in milliampere-hours (mAh). The larger the battery capacity, the longer the phone can be used on a single charge. For example, a phone with a 4000mAh battery will theoretically last longer than a phone with a 3000mAh battery under the same usage conditions. However, actual battery life is also affected by many factors, such as the phone's processor performance, screen resolution, and application usage.
Can Apple devices only use original batteries?
Apple device batteries are not limited to original ones, but using original batteries has many advantages.
The device and battery are incompatible and may cause a variety of damage to the device, including: hardware damage, performance degradation, software malfunctions, and data loss risks.
