Hi Tyler, I’d start with going to Settings>Battery>Battery Health Check your maximum capacity, if you replaced it recently, it should still how 100% or high 90’s. If not, try a factory restore, https://support.apple.com/en-us/HT201252 * Caution, you will lose any data not backed up !!! ***** If your maximum capacity is 100% or high 90’s take a look at your battery usage by app. See if it’s a particularly power hungry app. Try visiting the app store and updating your apps. that could help.
