From a professional point of view, 75% battery health is considered average or fair, but it is not necessarily good. Below are some reasons and steps to consider:
1. The battery health percentage is an indication of how much of the original battery capacity remains. So, 75% battery health means that the battery has lost 25% of its original capacity.
2. The battery health percentage does not have a specific threshold for being good or bad. It depends on the usage habits and needs of the user. However, generally, a battery health percentage above 80% is considered good, and anything below 70% is considered poor.
3. The battery health percentage also depends on the age of the device and the number of charging cycles. As a battery ages, its performance declines, and its capacity decreases. The more the battery is used and charged, the faster it degrades.
4. If a user is experiencing poor battery life or performance issues, it may be worth considering a battery replacement. Apple suggests replacing the battery when it reaches 80% maximum capacity or below to ensure optimal performance.
5. There are some steps users can take to maintain their battery health, such as keeping the battery cool, avoiding extreme temperatures, using optimized charging, and reducing screen brightness and background activity.
6. The latest iPhone models, such as iPhone 14, iPhone 14 Pro, and iPhone 14 Plus, come with improved and more efficient batteries that can last longer and perform better than previous models. Additionally, the latest version of iOS, iOS 16, also includes battery health features and optimizations to help users manage their battery health more effectively.
