Apple Intelligence is now available on iPhone, iPad, and Mac!
Hello, I have an iPhone 11 Pro for well over 2 years and for the last months it has been draining its battery too quickly even though it has a maximum capacity of 84%. The drop happens when it is close to 50% and it goes down to about 10%. Strangely the phone also has this behavior when charging, when it also skips this gap
here are some pictures:

This usually means that the battery has failed and needs to be replaced.
The Battery Health measurement cannot detect all possible ways that a battery can degrade or fail.

Hi Pedromaia17,
If you haven't done so yet, it's also a good idea to make sure your iPhone is running the latest version of iOS 16, since this can help with overall performance: Apple security updates. If an update is available, be sure to create a backup before installing it: Update your iPhone or iPad
From what the graph shows, it appears that the sudden drops in battery level seem to happen when your device is being used for 30-60 minutes. The Usage By App section shows that YouTube and Tik Tok are being used the most. When using some apps, specifically apps that are graphics-intense or when streaming videos, it's normal to notice that the battery may drain more quickly as opposed to when you're not using these types of apps.
The following articles have tips to help maximize battery life, and information on your battery:

Since you mentioned that this sudden drop also occurs while the device is being charged, you may want to reach out to Apple Support directly so they can look into this with you further. They can be contacted here: Get Support, or by calling the most applicable phone number from this list: Contact Apple for support and service.
Cheers.
Battery suddenly drops to near zero
