Q: battery usage and standby are the same in iPhone 5s

Hi, jdanielj.  

Thank you for visiting Apple Support Communities.  

I understand that your standby and usage times show the same amount of time.  I see you have adjusted settings with the issue persisting.  I would recommend manually backing up all of your data, restoring your device via iTunes and setting the device up as new.  Here are a couple articles that will help you with this process.  

iOS: About standby and usage time

Use iTunes to restore your iOS device to factory settings

Back-up your data

1. Check for iOS software updates. Install them if available.
2. Take a few minutes to transfer your content from your device to your computer to ensure that all of your critical data is safe.
3. Back up your device before you erase it.

 

Learn more about how to copy your backup to another folder, disk, or location for safekeeping.
