How to run a battery diagnostic on my iPhone?

Hi there Balpreet111,

If you are looking for a diagnostic of your iPhone device, you can either bring your iPhone to an Apple Store or Apple Authorized Service Provider for an in-person inspection: Find Locations. Alternatively, you can reach out to Apple Support directly here: Get Support. In either scenario, they will have the tools and resources needed to run a diagnostic and inspection on your device.

If you have a specific issue with your iPhone, we can also try to assist here in the Apple Support Communities. We just need to know a bit more about what is happening. Try providing the following details:

• What iPhone device are you using?
• What are you trying to do?
• What exactly is (or is not) happening when you try?
• Do you get any errors? If so, what exactly do they say?

Have a wonderful day!
