Apple users who have updated their devices to use iOS 11 have noticed problems with their battery life and app performance.
Some users claim that their phones ‘just get stuck on apps’ and that a hard reset is the only way to resolve the issue.
Apps including Reddit, Snapchat, Twitter, Facebook, Messenger, Safari, all appear to be affected.
For others the iOS update has drained their battery life – although there appears to be an explanation for this problem.
Apple users who have updated their devices to use iOS 11 have noticed problems with their battery life and app performance. The soon to be released iPhone X, which will launch with the new operating system, includes wireless charging
Wandera, a London-based mobile security company, found iPhones using iOS 11 took 96 minutes to empty their battery from 100 per cent charge.
Those on iOS 10 took longer, at 240 minutes.
Liana La Porta, head of content marketing at Wandera, conducted a study of 50,000 iPhones battery life.
The study found that battery drain may down to the iPhone’s Spotlight app.
This creates an index of all the files on the device, and organises all the files on people’s iPhones – an activity which drains battery.
In the report, 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.’
Angry Apple fans have also complained at a reduction in app functionality.

According to numerous posters on social media site Reddit, users are experiencing a massive drop in performance since upgrading to the latest operating system.
Many are complaining that apps are crashing when they try to open them, or are failing to load altogether.
User leejoness said: ‘Ever since I upgraded, launching apps is an absolute chore.
‘Safari, Reddit, ESPN, Yahoo, texts, etc all have a terrible time opening.
‘They either crash back to home, freeze and require closing the app or take well over a minute to load.
‘I never had a single issue with my 7+ before last night and now suddenly it’s like this phone is stuck in quicksand.

‘I’ve never had to hard reset this phone before but I’ve had to do it twice in the past two days.
‘Is anyone else experiencing this? Or is there a fix?’
Apple released its iOS 11 software last week and fixes for bugs are likely to be rolled out in future updates.
The update includes highly anticipated features for Apple devices including a more expressive voice for Siri, augmented reality apps, map updates, new emoji and shared Wi-fi.
iOS 11 also includes a couple of features that are specific to the iPhone X, such as FaceID and animated emoji, or animoji.
iOS 11 will only operate on 64-bit devices. Older models like the iPhone 5 (pictured) will no longer receive updates. It will also spell the end for 32 bit apps. You can check installed apps for compatibility using a built-in checker tool including in iOS 10.3 and later
Control centre
The control centre design has been given an upgrade, and can now be seen on single page, with greater depth on a 3D slider.
You can now also customize what quick shortcuts you’ll see in the Control Center.
Once you’ve created a set-up that you like, it can become a useful shortcut to functions such as your alarm clock or turning your battery onto torch.
But force pressing or long pressing some of the widgets, including the wireless icon, will give you a popup with more options.

Apple has also made the Apple Music app smarter.
In a preview for iOS 11, Apple wrote: ‘Apple Music learns your tastes, so you can ask Siri to play something you’d like.’

Siri
Siri has been given a new American voice that is said to be more expressive, in both the male and female form, thanks to a new visual interface.
The smart assistant will also be able to quickly translate English into Chinese, French, German, Italian and Spanish, with more language options coming soon.

What Siri learns on one device will be synced across all devices in iOS 11, but this is still private thanks to end-to-end encryption, Apple says.
A Type to Siri feature within accessibility settings is much slower, and Siri may respond via voice without the appropriate setting activated, but this can allow the voice assistant to be turned to type only.
App store re-design
Apple has completely redesigned the App Store in iOS 11.
A new tab, called ‘Today’ shows apps and stories about developers on a daily basis.
A ‘Games’ tab will show everything that is happening with games, and in-app purchases, such as new levels or upgrades.
Apps will also have its own tab, with dedicated features and charts for each app.

Shared Wi-Fi
The days of having to look for your Wi-Fi password to give a friend will be a thing of the past in iOS 11.
Apple has introduced a new shared Wi-Fi feature that lets users send their router’s password to another person’s handset.
Devices will need to be near each other and unlocked to connect.
ARKit is being introduced as part of iOS 11, letting users have augmented reality capabilities in apps, such as Pokemon Go
Augmented reality
ARKit has been introduced as part of iOS 11, letting users have augmented reality capabilities in apps, such as Pokemon Go.
Apple’s Augmented reality system uses the cameras on an iPhone to detect a flat surface, or ‘plane’ to put the virtual objects on, such as a table or floor.
With a combination of machine learning and the camera data, it can constantly adjust the image so the object appears secured to the correct surface without the ‘jitters’ or other AR systems.
ARKit also makes use of the camera sensor to estimate the total amount of light available in a scene and applies the correct amount of lighting to virtual objects.+
By taking advantage of the latest in AR technology, you can digitally redecorate your home, explore a city you’ve never visited, or even try on a new tattoo.
Augmented reality on the iPhone 8: Apple says dozens of apps will be available at launch. The feature will also work on the iPhone 6 and 7.
With new augmented reality apps, users can place virtual objects, like this dinousaur, in real-world scenes
Ikea’s first AR app, called Ikea Place, lets you put any item, from sofas and lamps, to rugs and tables into your living room to see how they look.
It sounds like a gimmick, but in practice its astonishingly good.
The app lets you virtually ‘place’ home products that are 3-D and true to-scale so you can make sure they’re just the right size, design and functionality for your room,’ Ikea says.
A sofa placed into the room MailOnline’s reporter was sitting in appeared at the perfect size, on the floor just as it should be.
New wallpapers
9to5Mac revealed that the iOS 11 GM code has 16 new wallpapers – three exclusive to the upcoming iPhone.
