iOS 11 battery drain is a real problem, study shows

Big new software upgrades might be awesome and exciting, but they are often accompanied by some unpleasant teething troubles. Apple's introduction of iOS 11 is the latest example of this, as many users reported a variety of problems after they updated to the latest version of the software. 

One of the most commonly experienced issues seems to be related to battery drain. This could be attributed to things like the Spotlight search feature needing to re-index all the files on a given device or recalibration of the battery charging mechanism which usually concludes after a few recharges. 

Normally, such early-stage ailments disappear quickly, but it seems that there is still an alarming number of users which continue to struggle with the battery life on their device. 

Security research firm Wandera took notice and conducted a survey which compares the average battery decay rate of devices running on iOS 10 and iOS 11. Wandera states that it has singled out 50,000 moderate to heavy users and averaged the results for a device to go from 100 to 0 percent over the course of three days. The results are startling, to say the least. 

The decay rate for iOS 11 stands at 96 minutes. That's much less than the 240 minutes achieved by devices on iOS 10. Of course, this is a rough generalization and the results will vary for each device, but the stats show that there is a real problem that is yet to be fixed by Apple. 

Cupertino has so far released iOS version 11.0.1 which addressed other issues related to Outlook and Exchange-based email accounts, but the incremental patch doesn't do much to increase time between charges. As such, if you're still on iOS 10, you might want to hold off for a little before upgrading.

Have you experienced an inferior battery life after upgrading to iOS 11? Let us know in the comments below.

At that price you expect your device to be top of the notch, but no. Apple screws you at the best problem possible.

Wait! You're usually siding with Apple and calling out people who call out Apple. But today you woke up on the wrong side of the bed and you're actually speaking against Apple? I am surprised!

Apple had made even dumber decisions with the iPod Shuffle (3rd gen anyone?), but to call being behind the staple hardware features "value for what you get" is corporate arrogance. Tim should just let some other higher-up speak for his product line. But if someone likes the iPhone X more power to them, not me...

I don't think its battery-gate, because the problem isn't the battery itself.

A real problem?! Not for iPhoneArena apparently. According to their usually awesome review of Apple products the iPhone 8 has a stellar battery life

Battery life issues aren't necessarily a universal thing. Check out the iPhone sub-reddit where some users are reporting 12-18 hrs of usage time with the 8+, which is REALLY good. That's like 8 hrs SOT for Android users, the sweet spot IMO. Having said that, iOS 11 has been a total crapfest early on. They somehow managed to make their new phone SLOWER than their old one... f**king incredible.

I haven’t had battery issues on an 8 Plus or a Pro 10.5, but I agree, they are slower than they should be.

I faced this issue, factory reset helped a little but battery life is not as good as iOS 10. It still drops nearly 40% faster (comparing battery remaining by EOD).

It's been hit or miss with me. Some days, battery life is REALLY good. Other days, it's a total s**tshow. Then again, I've the 7+ and not the 7 or 8, so my battery life has always been at least decent up until 11 dropped. Apple has really gotten ahead of themselves and forgotten what got them their customer base in the first place: good... stable... SOFTWARE!!! Well, customer support too, but that's besides the point. Should've just dropped the iPhone X next year and polished the software until they could procure more resources for it's release.

My iPad Pro 10.5's battery life was great before iOS 11, and after I updated it, it got even better. I still have the clear notifications bug, but as for battery life, I can't complain one bit.

Wife's 7+ battery life post ios 11 is crapshow too. Also the phone function went to total s**tshow when she tried to call her mother. Multiple tries later, she ended up restarting the phone

And Apple fans joke about Android's updates. Apple makes you guys afraid to update.

Former Verizon rep, a lot of people complained about Verizon being slow to launch updates for Android devices, yet there were few bugs when updates went out. Apple pushed out update after update to fix the bugs introduced in the last update. One nasty update for the iPhone 4s killed the wifi antenna so users were left with only mobile data, it couldn't be fixed wither because it physically cooked the antenna. There was another that went smoothly for most people, but 10s of thousands of iPhone and iPad users lost service to Verizons network. Of course Apple blamed Verizon but Verizon had NOTHING to do with they update process, meanwhile we have angry customers coming into the store and all we could do was tell them they had to wait for the next update. Nasty situation.

Makes you wonder why Apple keeps messing up their updates when they only have a few different devices to support and "the best" software developers...

They have the best APP developers. Nobody has complement their software team in years IMO. But like I said above, they're doing too much right now. Stop trying to play catch up with Android OEMs for no reason Apple... you don't need to do that. Focus on what got you here; security, quality, and pure stubbornness.

I don't know if Apple really ever had great quality products, or if the products around them were so bad it simply made Apple seem better. Because right now others are doing way better. I don't like Vanilla Android, but using it vs IOS is so much better

"I don't know if Apple really ever had great quality products" You're clearly mistaken to believe such tripe. I get that Android users despise iOS with the passion of the Pantheon, but stop with the nonsense. The iPhone, IPad, and the iPod before that were ALL extremely high quality products... period. "Because right now others are doing way better." Doing better at what? "I don't like Vanilla Android, but using it vs IOS is so much better" And hundreds of millions would disagree with that opinion. Just because something is better to you, does not make it better to the masses.

It's an opinion we can choose to believe anything you want. I didn't try to convince you of anything. Apple has always struggle with software. Look what they did to Final Cut. It's basically ruined. I stopped using Premiere because FCP was better until Apple ruined it. Mac OSX is nothing but Steve NextStep OS. It is the worse variant of a NIX operating system ever. It's good at things that don't matter, because Windows Pcs are equally as good and cost less. QuickTime, iTunes, IOS , keynote Nd the rest are all terrible vs similar apps on any platform you can name. Apple has never been good. It's why Office, Macromedia (now Adobe), and other apps Re so popular on Macs vs Apples own apps. ITunes is hated morw than Windows. That is a fact! Even iPhone fans hate using iTunes. Safari is bad too. Xserve vs Windows Server is just a no-brainer. Apple has always made great hardware in thwir combinations and getting extra speed and stellar graphics in the past. But software has always trailed the competition. That is fact! Not opinion.

Apple has never made great software. QuickTime is a bigger resource hog them Windows Media Player. Safari has more bugs than Internet Explorer ever had. Mac OSX runs decent. But for an OS that runs considerably less software vs Windows, it is slow. iOS? The biggest issue of me is tying to much to a single button and now there are way to many gestures to remember that it just makes using IOS a chore. Apple is too busy being different, that they are losing appeal, because it now just takes to much work to navigate iOS.

Without updates like these to iOS no one would bother to upgrade their phones
