Have you ever replaced the battery in your iPhone 11? Chances are the battery has used its useful life and is in need of being replaced.
To see if the phone can still operate, try a forced restart on it --> Force restart iPhone - Apple Support
If it starts, after signing in, go to Settings > Battery > Battery Health and if it is at 80% or less, the battery MUST be replaced.
You can schedule an appointment at your Apple Store Genius Bar for that here --> iPhone Battery Replacement - Apple Support
Do NOT let anyone other than Apple or an actual Apple Authorized Service Provider (like BestBuy in the US) replace the battery. No one else has access to authentic parts and putting non-authorized parts in your phone will make the phone ineligible for service from Apple, make it impossible to trade in or resell.
