Apple’s new iOS 13 update ‘continues to be a disaster zone’, with users reporting that it drains their batteries.

Multiple reports have claimed the iOS 13.1.2 is draining the battery life in just a few hours – and some said devices are also heating up while charging.

Apple has yet to release an official statement, but the issue appears to be affecting a variety of models –from the iPhone 6 to the iPhone 11 Pro Max.

Apple rolled out its iOS 13 software last month and although it is packed with an array of changes, such as picture editing, menstrual tracking and improved privacy features, it has also come along with a few bugs.

Users have experienced dropped calls, lost contacts, deleted emails. Even Siri was even found to have issues, with the smartphone assistant making calls on speakerphone by default.

Now, many are finding their iPhone battery will either not charge or keep a charge for long.

‘Apple iOS 13.1.3 update is killing my iPhone 7 plus battery. Getting 70% battery drain in 2 hrs. Phones is laggy and running hot. What’s changed since 13.1.2 to cause this,’ One frustrated user shared on Twitter.

Another Twitter users shared ‘Thanks Apple. Used to have a great phone that would last me the day. With iOS 13.1.3 installed I now have a phone that overheats, drains all battery in 3 hours and won’t charge properly anymore. But at least I now have Memojis. Awesome.’

Apple had high hopes for it’s iOS 13, but the update fell short among users as the initial release was plagued by bugs.

The tech giant had to quickly release a beta upgrade to iOS 13.1 a week ahead of schedule to squash the worst, most commonly reported problems.

Then it released the final version of 13.1, adding a feature to boost battery life, but then 13.1.1. and 13.1.2 quickly followed a maintenance or bug fix updates that attempted to fix the problems that popped up in 13.1.

Although Apple has not yet announced how it will fix the issue, users may want to switch to Dark Mode until then – a YouTuber found the feature increase battery life by 30 percent.

The experiment was conducted by YouTube channel, PhoneBuff, which used iPhone XS Max handsets.

The team used two robotic arms for the tests, which interacted with the smartphones – they went online, sent emails, searched locations on Google Maps and more.

After just two hours into the experiment, the Dark Mode iPhone was on 88 percent and Light Mode handset had dropped to 83 percent.

At four hours, Dark Mode was on 72 percent while Light Mode had just 57 percent.

The Light Mode iPhone went dead at seven hours and 33 minutes, while the Dark Mode phone still had 30 percent left in its battery.

However, the YouTubers noted that results may vary, as battery life will depend on how bright the screen is set, the iPhone model and other factors.
