There are a few reasons why your battery health might have dropped so quickly. One possibility is that you've been using your phone more heavily in recent weeks. Another possibility is that you've been using your phone in hot environments, which can also cause battery health to decline.
Your habit of using your phone's hotspot while plugged in could also be a factor. When you use your phone's hotspot, it's essentially acting as a mini-router, which can put a lot of strain on the battery. If you're doing this for many hours at a time, it's likely to contribute to battery health decline.
It's difficult to say for sure whether or not your hotspot habit is enough to cause such drastic battery aging. However, it's certainly a possibility. If you're concerned about your battery health, you can try to reduce your phone usage or avoid using your hotspot for long periods of time. You can also try to keep your phone in cool environments.
Here are some other tips for maintaining your iPhone's battery health:
- Avoid letting your battery drop below 20% or charge it above 80%.
- Avoid using fast charging or charging your iPhone with an iPad charger.
- Don't leave your iPhone in hot or cold environments.
- Close apps that you're not using.
- Turn off background app refresh.
- Disable location services for apps that you don't need them for.
If you're still concerned about your battery health, you can take your iPhone to an Apple Store or authorized service provider for a diagnosis.
