Hi mikaela11803.
Start by making sure that the microphone setting on the AirPods is not set to Always Left because that can explain such a big difference.
Adjust the settings of your AirPods - Apple Support
After checking the settings, try resetting the AirPods.
Reset your AirPods - Apple Support
If you take both of those steps and the AirPods are still discharging at such an uneven rate and if you purchased them via Apple.com or at an Apple Store and are within the 14-day return period, you may want to do that. If you're beyond that period or purchased them via another avenue, then this is a warranty issue. You'll find a link to Apple Support in the second article linked above for setting up warranty replacement.
Cheers.
