Most Android devices are now defaulted with a fairly simple Recovery mode with features like Reboot System Now, Apply Update from ADB, Apply Update from External Storage, Wipe Data/Factory Reset, Wipe Cache Partition, Apply Update from Cache.
Just like a lot of other things with Android, even the Recovery Mode can be customized to do more things.

All Android phones come with built-in recovery mode that is separate from the original operating system.
The recovery mode is used to access different features of the phone without accessing the phone’s OS.
The main function of the recovery mode is to fix the phone while staying away from the faulty OS of the phone.
