Here’s the proof that iOS 11 has slashed your iPhone’s battery life by up to HALF
THE latest software for Apple iPhones is cutting people's battery life by up to half, analysts have claimed.
Experts suggested that people who installed iOS 11 on older devices were seeing the juice drain much more quickly from their gadget - and iPhone owners agree.
Two weeks ago Wandera, a business phone maintenance company, found that iPhones using the brand new iOS 11 took 96 minutes to empty from 100 percent charge and that those on iOS 10 took much longer, at 240 minutes.
Apple has released two updates to tackle the battery life: iOS 11.0.1 and iOS 11.0.2.

But although the second of these fixes an annoying "crackling sound" some people have heard during calls, experts have claimed it does not fix the battery life.
In an article for Forbes, : "The battery issues which plagued iOS 11 and iOS 11.0.1 appear to continue, as does poor performance and instability."
However, Wandera later found there was a "positive change in iOS 11 battery life after the release of 11.0.1".
It wrote: "iOS 11 time to decay from 100% to 0% is now 159 mins. That’s a 63 minute (or 65%) improvement compared to the iOS 11 time to decay in the first analysis which was 96 minutes."
Originally, Wandera conducted a study of 50,000 iPhones, surveying "moderate to heavy iPhone and iPad users" on both operating systems to compare the average battery decay over three days.
They found that iOS 11 runs down the battery more quickly on older devices.
Battery drain is a common iOS problem that seems to occur immediately after a major upgrade.
Matt Vlasach, director of product at Wandera, said: "It is a simple reality of software: there will always be bugs in new major OS releases, which are constantly pushing the limits of the devices they are running on.
"This, in turn, burns battery and always causes a new uproar about battery performance. However, it is inevitable that these problems will be addressed and improved as time goes on, until the next major update.
The battery drain could be down to the fact that the iPhone's Spotlight app - which creates an index of all the files on the device - is busying itself in the background and organising all the files on people's iPhones.
There is also activity going behind the scenes just after installing a new operating system, which is why Apple advises users to make sure their gadget is plugged in whilst updating.
La Porta wrote: "This is partly due to Spotlight re-indexing and other behind the scenes shuffling.
"New functionality in iOS 11 could also be responsible for draining the life out of your phone.
"Animoji and iPhone X’s FaceID hardware use face-scanning technology relying heavily on the camera which is a notorious battery sucker.
"The hardware enabling this advanced facial recognition in the iPhone X could be the reason there is such a dramatic difference in battery decay rate."
However, you might want to take this last point with a pinch of salt because no-one has actually used the iPhone X properly yet apart from Apple's inner sanctum.
There's also the theory that people are just more excited about using their phones following an upgrade.
"We suspect it is also a case of Apple fans wanting to test out all the shiny new features right off the bat," she added.
Huge numbers of people have taken to social media to grumble about the iOS 11 battery life issues.
You can see some of the tweets below.
Those tempted to switch back to iOS 10.3.3 to tackle the battery issue should beware.
Doing so could leave you open to hackers who want to exploit your precious gizmo and steal your personal information as it doesn't have the latest security.
There are several ways you can keep juiced up.
First, limit the number of apps that can refresh in the background.

Go to Settings > General > Background App Refresh.
You can also limit the number of apps that can access your location in the background by going to Settings > Privacy > Location Services.
It's also been suggested you could switch off functions like "assistive touch".
To turns this off just go into Settings, followed by General and Accessibility and there will be an option marked Assistive Touch.
There's always low power mode until Apple brings out new updates that could address the drain.
Just click on the Battery option in settings and switch it on.
