iOS 11.4 is reportedly wrecking the battery life of iPhones, from the older iPhone 6 to the latest iPhone X. No one knows for sure why this is happening, but there are a couple of theories about.
To recall, iOS 11.4 arrived on iPhones at the end of May. Battery drain complaints followed soon after. One particular user on Apple’s official forum claims that their iPhone 6 was working fine until iOS 11.4 came along. The handset went from lasting an entire day to barely making it to half a day.
We haven’t faced any battery draining issues after upgrading our iPhone X to iOS 11.4. But we have noticed that the smartphone has started over-heating if we watch videos for more than 15 minutes continuously. It also gets exceedingly hot when we play videos while the battery is below 20 percent capacity.
iOS 11.4 Battery Drain Complaints
Another says their iPhone 6S goes from 100% to 40% within a couple of hours on standby. One person’s iPhone 6S Plus dropped from 50% to 20% in a matter of minutes when they weren’t even using it. As per the iPhone’s battery health page, it was at 90% capacity.
Many of the iPhones suffering from the issue are at optimum battery health. Some folks assert that they replaced their battery recently, so the battery itself probably isn’t to blame. Since it’s likely not a hardware problem, the only conclusion to draw is that it’s a software issue.
Thousands of people are chiming in on these discussions, so it’s clearly a widespread concern. Many are choosing to go back to iOS 11.3.1 to fix the problem. Others say switching off Wi-Fi or connecting only to 2.4GHz Wi-Fi networks resolves the issue.
It seems 5GHz Wi-Fi networks negatively impact some iPhones, particularly the iPhone 6 and iPhone 6S. Apple hasn’t breathed a word about this battery drainage controversy yet. Hopefully, it’ll fix the problem in the next iOS update.
In fact, a couple of people on the iOS 11.4.1 beta say that everything went back to normal the moment they installed it. Now we just have to wait for Apple to roll it out to everyone.
