Pls my iPhone 11 pro max battery is 56 can u help me with that

In addition to all the advice you've been given, PLEASE don't delay getting the battery replaced. Apple suggests replacing the battery when its health dips to 80%. At 56% your battery is SEVERELY depleted and batteries which are severely depleted can swell or worse, which could permanently damage the phone. Either get the battery replaced as soon as possible or buy a new iPhone.

Go to this web site for information about how to request battery service for your iPhone: iPhone Battery Replacement - Apple Support

For cost and availability, enter your model information in the "Get an estimate" box at the bottom. (It is best that you do this since sometimes contributors here forget this is an international forum and not everybody asking questions lives in the contributor’s country.)

The battery is long long overdue for replacement.

Make an appointment at the Apple Store / Genius Bar or take the phone to an authorized Apple service shop in your area. You can find a list of authorized shops in your area using this link: Find Locations
