How to Judge if Your iPhone Battery isn't As Good As It Used to Be?

 In today's age of smartphones, iPhone is a popular model that accompanies us through countless busy days. However, as the use time increases, you may feel that the battery of your phone seems to be "not durable". So, how can you tell whether your iPhone Battery is not as good as before? Phonefix will reveal the details for you.

1. Check with built-in features
Check battery percentage and usage: Open Settings, tap Battery. You can see the percentage of battery power used by each app in Battery Usage by App, and view the Activity graph to see how long the screen is on and off, and which apps are using the most power. If certain apps use unexpectedly high amounts of power, or if power consumption is high when the screen is off, it could indicate a battery problem.

2. Check Battery Health
For iPhone 16, tap Settings > Battery > Battery Health; for iPhone 14 and earlier, tap Settings > Battery > Battery Health & Charging. Maximum Capacity shows your battery's maximum capacity relative to when it was new. A new battery should be 100%. As your device ages, the percentage drops. Generally, if it's below 80%, the battery's performance may be severely affected. Peak Performance Capacity tells you if your battery is running at normal peak performance. If you have an older iPhone with a lower capacity battery, you may see a message that your battery's health has significantly degraded.

3. Judging by usage experience
Shortened battery life: If your iPhone used to last a full day with normal use, but now needs to be charged in half a day, or the time it can be used after a full charge is significantly shorter than before, this indicates that the battery is not as good as before.

Frequent charging: You find that you need to charge your phone more frequently than before even with the same usage pattern. For example, you used to charge it every other day, but now you have to Charge Phone every day, or even several times a day.

Sudden shutdown: Even if the battery is not particularly low, the phone will suddenly shut down, or shut down unexpectedly during normal use, which may be due to the battery not being able to provide stable power.

4. Observe Performance Changes
Sluggish Performance: If the phone runs slowly, apps take longer to load, and the frame rate drops when scrolling, it may be due to the battery's inability to supply sufficient power, causing the phone to reduce performance to Protect the Battery and other components.

Overheating: If the phone heats up quickly during charging or normal use, it may also be a sign of battery problems. A deteriorating battery may have abnormal chemical reactions, resulting in increased heat generation.

5. Use Third-Party Apps
There are many third-party battery apps available in the App Store, such as Clean Battery, Zen Battery, Battery HD+ and Battery Life. These apps can provide more detailed battery information, including real-time battery temperature, voltage, and charge and discharge times. They can also offer tips to help your battery last longer.

Through the above methods, you can more accurately judge the health of the iPhone battery. Once you find that the battery performance has seriously declined, you need to consider replacing the battery to revitalize your phone.
