The launch of Apple's latest operating system iOS11 in September brought with it a lot of good things–like Wi-Fi sharing and payments through iMessage–and some bad things too, like giving people the tools they need to record private messages without the user knowing.

But the most annoying feature to come out of the upgraded operating system has to be the effect it's had on battery power. Namely, the fact that it has been draining the battery life out of iPhones everywhere after just a few hours of use.

Damn iOS 11. Left the house with battery at 100% and it”™s now at 18% 😭

Of course, Apple has been rolling out its first update to iOS 11 (11.0.1) recently, with some users reporting that it appears to have fixed their battery problems, but if you're still struggling to keep your phone alive for a whole work day then the good folks of Twitter have shared a few troubleshooting options for you to explore.

And, by the sounds of it, any number of things could be contributing to your bad battery problem, so prepare to get stuck into some detective work.

One user suggests double-checking your auto-brightness settings, which are hidden in the Display Accommodations section of the Accessibility menu, as they may have been switched to 'on' by default.

Want to save battery life w/ #iOS11? Turn off Auto-Brightness hidden in Accessibility-Display Accommodations. Default on even on off. #Apple

Another user has managed to fix their battery-draining phone by updating their background app refresh settings after the iOS upgrade automatically turned it on for every app:

iOS11 battery issue solved: Pretty sure upgrading turned on background app refresh for every app. I fixed it yday and today is much better.

And if you're still having problems with your battery life, one user suggests turning off assistive touch, which is advice that apparently came straight from the Apple developer forums:

For those who have issues with battery draining so fast on ios11, try to turn off your assistive touch. Replies from the dev forums 👌

Basically, it's possible iOS11 has reset all of the battery-saving measures you've put in place on previous software updates, so it's worth taking the time to go back through your settings and get it back to just how you like it.

And then maybe your phone won't power down before you get a chance to fully take in that Snapchat you just opened.
