Apple iPhone 8 Goes On Sale

IT’S something smartphone users often lament: a new software update can sometimes mean diminished battery life.

Since rolling out the official version of iOS 11 last month to coincide with the release of the iPhone 8, some Apple fans have reported a frustrating reduction in their battery life.

In fact, a study of 50,000 moderate to heavy iPhone and iPad users carried out after the new iOS was launched found the average battery life tumbled from 240 minutes on the iOS 10 operating system to 96 minutes with iOS 11.




Apple has already released a couple of updated versions of the latest operating system designed to address some of the user issues, including the hit to battery longevity.

But if you’re looking for a few tricks to increase the battery life of your iPhone, it seems like a good time to remind you that there’s a lot you can do.


The most obvious and simple solution is to enact Low Power Mode but it’s not something you want to be using all the time.

Your phone will automatically suggest you use this mode when your battery drops below 20 per cent but you can switch it on in the Settings under the Battery category to conserve some mobile juice when needed.

The mode turns down the display brightness, reduces the time for auto-lock to kick in and disables various features like background app refresh and automatic downloads.


If you’re not that keen on Siri being at your beck and call every second, you can turn stop the digital assistant from constantly listening to you. You can still use Siri by holding the home button, but she (or he) just won’t be listening out for you to say “Hey Siri” to engage.

You can turn the feature off by going to Settings, then Siri & Search, then turn off Listen for “Hey Siri”.


This feature is for people who have difficulty touching the screen and is designed to assist with your finger dexterity when doing gestures like pinch or multi-finger swipe on the touchscreen.

If you happen to have it turned on, it will contribute to draining your phone’s battery so to switch it off, go to Settings > General > Accessibility > AssistiveTouch.
