If your iPhone’s battery life has taken a substantial hit since the upgrade to iOS 13, stop reading and head to the Settings app on your handset to update to the latest version of Apple’s mobile operating system. (After that, feel free to come back and keep reading)

Apple has pushed-out a new version of iOS 13 designed to quash more of the bugs and glitches that have plagued its latest upgrade.

Although it doesn’t directly address battery life, it’s more than likely there are some improvements under the bonnet here that found address some of the underlying issues that could be causing your iPhone battery to drain faster than usual. Upgrading your iPhone to a new version of the operating system could also overwrite any gremlins in the code that may have snuck in during the last iOS 13 upgrade.

A vast number of social media users have voiced concerns about the lifespan of their battery since the upgrade to iOS 13.

One Twitter user, known as @kiran7karthik, moaned: “whats wrong with ios 13.1.2 in iphone7. Unable to use phone as battery drain happening like hell with lot of heat generation while attending calls. #iphone7 #iOS1312. Sort out this soon @Apple @AppleSupport”

Another, known as @MaltheshMY, posted: “Most of the application is crashing, battery is draining, mobile is heating, making/receiving call is becoming tough after updating ios 13.1.2 @Apple #iOS1312”

Thankfully, it seems Apple is listening. The latest update – iOS 13.1.3 – is seemingly designed to fix a number of these complaints.

According to Apple, the iOS 13 update has a fix for a bug inside the Phone app that prevented handsets ringing when they received an incoming call. Bugs that caused issues with the Apple Mail app, Voice Memos and Health apps have been addressed.

Apple says that a number of Bluetooth related issues should now be fixed, too. iPhone users had complained about their handset disconnecting from Bluetooth speakers, car infotainment systems, hearing aids and headsets, among others.

There’s also a truckload of fixes inside iOS 13.1.3 that will appeal to Apple Watch users, including a glitch that prevented notifications appearing on the Apple Watch, and another that could stop the smartwatch from pairing successful with a handset.

Clearly, this is a very important update and one that should probably install as soon as possible.

To update your iPhone, you’ll need to head to Settings > General > Software Update.

iOS 13 was first unveiled during the World Wide Developer Conference earlier this summer before the release date was confirmed during the iPhone 11, iPhone 11 Pro and iPhone 11 Pro Max announcement last month. Apple launched iOS 13 in September with a number of new features, including a system-wide Dark Mode to make the operating system easier on your eyes at night (and save battery life on handsets with OLED displays), as well as more granular privacy controls, a redesigned Reminders app, in-depth analysis and insights on your health data within the Activity app, an overhauled Photos app that uses AI to pick the best shots to summarise your memories.

It’s a lot. In fact, it might even have been too much. Apple has struggled with bugs since the update launched, bringing forward iOS 13.1 by six days to try to get some of the patches and fixes in users’ hands as soon as possible… something it’s still trying to do with the latest speedy iOS 13 update.

Apple has also pushed-out an iPadOS update with similar fixes and patches.
