🚅 iPhone speed on iOS 13.3.1
We used our iPhone 11 and iPhone XS Max with iOS 13.3.1 Beta 3 build for over a week as our daily drivers. Neither of the devices ever slowed down.
However, on some of the older devices, you may notice a bit of sluggish and slow performance right after installing the update. This is common with any iOS update you may install. It happens because your iPhone re-indexes the file system after installing an update which puts pressure on the processor and thus slow speed on some older iPhone models.
🔋 Battery Life on iOS 13.3.1
Battery life on iOS 13.3.1 is normal. And with the addition of “Networking & Wireless” toggle in Privacy » Location Services setting to disable location services for Bluetooth, Wi-Fi, and Ultra Wideband, battery life only gets better with iOS 13.3.1 update.
However, know that you may experience a battery drain for up to 24 hours of installing the iOS 13.3.1 update on your iPhone. This is normal any iOS update as your iPhone re-indexes the file system after installing a system update.
The iOS 13.3.1 is a minor update over the previous iOS 13.3 release. It’s less than 300 MB in size. That gives it less room to mess with your iPhone, and based on our tests of the iOS 13.3.1 Beta 3 build we think it’s safe to install iOS 13.3.1 on your iPhone too.
