In daily life, batteries are an indispensable source of energy for many electronic devices. From mobile phones, laptops to electric cars, we all rely on batteries to maintain the normal operation of our devices. But as the use time increases, the battery will gradually age and the performance will decline. So, how to tell if the battery is aging? Here are a few practical methods for you.
I. Common signs of battery aging
1. Battery life is significantly shortened
- It used to last a whole day, but now it needs to be charged in half a day.
- The battery percentage drops abnormally fast (such as more than 20% power loss in 10 minutes).
2. Charging speed slows down or abnormally
- The time required to fully charge increases significantly.
- The battery display is unstable during charging (such as suddenly jumping from 30% to 50%).
3. The device is seriously hot
- It gets noticeably hot during light use (such as browsing the web).
- The temperature rises abnormally during charging, and even triggers overheating protection.
4. The battery display is inaccurate
- The battery suddenly returns to zero and shuts down, and it shows that there is power when the charger is plugged in.
- The same battery level is displayed for a long time and then drops suddenly (such as being stuck at 50% and shutting down directly).
II. Scientific methods for detecting battery aging
1. Use system-provided tools
- iPhone users: Go to [Settings] → [Battery] → [Battery Health] and check the "Maximum Capacity" (replacement is recommended if it is less than 80%).
- Android users: Some brands (such as Huawei and Xiaomi) provide a "battery health" detection function.
- Laptops: Windows can generate a battery report by entering powercfg /batteryreport in the command prompt; Mac can view the number of cycles and design capacity in [System Report] → [Power].
2. Third-party software detection
- AccuBattery (Android): Analyzes battery actual capacity, charging speed and other data.
- CoconutBattery (Mac): Detects battery cycle number and health.
- BatteryInfoView (Windows): Displays the difference between battery design capacity and actual capacity.
3. Observe the number of battery cycles
- The life of a lithium battery is usually 300-500 complete cycles (one cycle = charging from 0% to 100%).
- The number of cycles can be queried through system tools or third-party software. After more than 500 times, the capacity may decay to less than 80%.
III. Practical tips for extending battery life
1. Avoid extreme charging and discharging
- Keep the battery level between 20% and 80%, and avoid long-term use at 0% or 100%.
- Use the "optimized charging" function (such as [optimized battery charging] on iPhone).
2. Control temperature
- Avoid using/charging in high temperature environments (such as exposure to the sun) or low temperatures (<0°C).
- Remove the phone case when charging to prevent overheating.
3. Use original or certified accessories
- Poor-quality chargers may cause voltage instability and accelerate battery loss.
- Although fast charging is convenient, long-term use may affect the lifespan. It is recommended to use it alternately with ordinary charging.
Conclusion
Battery aging is a natural phenomenon, but through scientific testing and reasonable maintenance, its life can be significantly extended. Pay attention to battery health regularly and adjust your usage habits in time to make your device "powerful" and last longer!
