"iPhone battery: I have iPhone 13 mini which is currently running on ios 15.5 and recently I’ve started to face some major battery draining issues. Like I have to charge my phone twice in a day. Battery drains faster when I’m not using my phone like overnight or throughout the day. Any solution? Background app refresh is already turned off."

Troubleshooting a Draining iPhone:

System resources a likely being swollen up, so to speak. So, start with clearing space. Try the following:

I. Cool Down the iPhone:

For a few hours, perform the following...

• Power Off: the iPhone for a bit
• Unplug: any Cables
• Place it Atop: a Laptop Cooler
• Keep it in: an open space
• Keep it Out of: direct sunlight

II. Clear Space:

Having little empty space can heat things up. So, here is what to perform...

A. Clear Temporary Internet Files:

Clear your Temporary Internet Files(Cookies & Cache) of Safari:

• Cookies perform remembrance of certain site-entered data.
• Cache keeps a snapshot of the last time you visited a site.
• Go Here: Clear the History and Cookies from Safari on your iPhone, iPad, or iPod Touch - Apple Support

Also...

B. Clean TV and Music Libraries:

Remove all unneeded files from your TV and Music Libraries. Full-Movies take up 2-4GB typically, and a bunch of those would take up a load of storage, ideally. So, if you have any movies that are not needed, then delete them.

Also...

C. Clear "Other":

Clear the storages named "Other". It basically contains unnecessary files such as caches that are used for system ease of use - all of which gather over time: How to Clear "Other" in your iPhone's Storage - Use Backup - User Tips. Caches would be being used for remembrance of application use.

You should be charging your iPhone overnight, every night.
