iOS 10.1.1 Update Really Causing Battery Drain And Shutdown Issues, Replacements

Being reported by iPhone users that after updating to iOS 10.1.1 firmware have begun drastic battery drain and shutdown issues.

Following the iOS 10.1.1 earlier this month to fix a bug with how Health data was handled for certain users, it actually introduced some inadvertent issues that are really causing a growing number of device owners concern. It’s a good idea when you update iPhone and iPad to the latest available firmware when it shows up as Software Update, but the increasing number of device owners reporting new battery and shutting down issues on Apple’s support forums would suggest that all is not right with iOS 10.1.1.


Apple may have released iOS 10.1.1, promising among other things, “stability improvements and bug fixes,” but some believe it’s also carrying a new battery bug then. According to the growing thread on Apple’s support forum now extends over more than thirteen pages, with each message on the thread all seeming to suggest the same damn battery drain and shutdown thing; that upgrading a device to iOS 10.1.1 introduces random battery life behavior that causes the device to shutdown as if it had no power left.

The report also claims the update is unexpectedly draining iPhone batteries, and there’s an also active discussion on Apple’s own support site where customers are reporting iPhone 6 and iPhone 5S devices unable to last a full day without charging. Others report iPhones dying with “30 to 50% charge left”.

Rather than introducing an issue where batteries rapidly drain down to 0% quicker than normal, it seems that iOS 10.1.1 contains problems that sees the phone entirely shutdown when a r battery percentage is reached. Like this device that actually shutting itself down when it shows that it still has 25, 30 or even 40% left in the bank.

This report however comes just a week after Apple agreed to replace the batteries on a small number of iPhone 6s devices that were prematurely losing steam. Device owners are also taking to Twitter and other social networks to vent their frustration with the issue on iOS 10.1.1 battery drain and shutdown, with one users sarcastically suggesting that iOS 10.1.1 ships with Apple’s “most advanced battery-draining capabilities yet.”

Is iOS 10.1.1 Battery Drain Issue Solved?

Unless Apple issues a fix for this issue soon, it could have a number of other replacements on its hand. Until then, you can try downgrading back to iOS 10.1 as Apple is still signing that firmware to see if that fixes the problem.

Here’s How To Find Out If Your iPhone 6s Is Eligible For Free Battery Replacement

Step 1: Find your iPhone’s serial number. It’s located on the back of your iPhone, or if you’d prefer, it can be found in Settings > General > About.

Step 2: Look out for the following characters, found in the 4th and 5th spot of your iPhone’s serial number.

  • Q3
  • Q4
  • Q5
  • Q6
  • Q7
  • Q8
  • Q9
  • QC
  • QD
  • QF
  • QG
  • QH
  • QJ

If you device’s serial number including any of these, then you’re good to go to the Apple Store, safe in the knowledge that your iPhone 6s is one of the faulty ones and eligible for free battery replacement, that too even if it’s out of warranty.
