iOS 11 draining battery...

Have you tried a reset?

iOS Reset -

With an iPhone 6S and lower, press & hold the Power and Home buttons simultaneously, ignoring the red power off slider, until the Apple logo appears. Then release both buttons. This should not affect any content on the device, it is similar to rebooting your computer. With an iPhone 7, press & hold the Power and the Volume Down buttons.

After the update, using the mobile just a few moments in the day, I got 30% (or less) in the end of the day. Just an example, today I openned a game "Trivia Crack" and just during the refresh of data... about 10 seconds, the battery drainned 4%. If I read 10 messages through safary browser, battery drain about 11% !

This update is very bad... Please fix it as soon as possible! Today I updated to iOS 11.0.1 but the problem continues.

Hi,

i updated my 6s to 11.0.2 also and after using it normally -not much- it still drains the batt.

Yesterday I disabled the background app refresh... and also email push configuration... i open the email app manually to see if there is any new email. i fill the batt during the night untill 8am... But even so, the battery lasts less than iOS 10.3.3. And now we're trapped in iOS 11.0.2. because the downgrade is not possible...

I've screencaptured the draining moment. At 11:26am it was less than 20 minutes of screen use -really hard working day ;-) - In less than 20 minutes of screen use, it drains from 100% to 88%... and in 3 minutes it goes from 93% to 88%... i was only using whatsapp through wifi.

In iOS 10.3.3. my 6s lasts 6h30´ of screen time using normally. And now ( 9pm) im 2h39´ and im 30% remaining. I think about 2 hours less than previous version of iOS.

i regret upgrading to iOS 11 😢

p.s. i edit... and as you see in the picture... 11:26 it drains 3% in a minute without running apps in the background.

Hi guys!

I have Iphone 7 plus.

Look at my print screen! What are happening with my app store and my battery?

I switched off automatic downloads and background app refresh. I have charged the battery 3 times for today.

Hi,

I use iphone 6 and exactly I had the same problem once upgraded to ios 11.

I was very much irritated and contacted apple, and this solution was provided.

This works perfectly for me, you can also try. The battery consumption has reduced a lot.

factory reset using itunes, all your content would be erased, so back up before doing so.

thanks

Hi,

after reseting twice... and switching off many times, my iPhone 6s is still draining the batt.

After resetting or after rebooting it shows 60% batt and after 10 seconds it start showing 59%... 58%... until 55% only in 10 seconds. Without having any app running in the background, only viewing the springboard.

In iOS 10.3.3. using the mobile normally it last for almost 6:30 hours of screen time. Now it can't reach 3 hours.

It seems like the iphone is calculating something in the background... the apps are running a little bit slower when launching them they make some kind of jump or bulky running. The os is telling me that i have new memories and new people found in pictures... but its been 4 days since i upgraded to ios 11, i thought that it would be 1 day of reindexing things and pictures. Could be the reindexing of almost 10.000 pictures the reason of this batt draining? i know my pictures are not a great deal but... i don't want to erase them yet... 😝

i hope Apple'll find a solution as soon as possible.

Thanks

One step that can ultimately tell if your issue is your actual battery or software is to back everything up to iTunes/iCloud and restore to factory settings using iTunes.

If you restore using iTunes (more specifically iTunes on a computer, not going to Settings > General > Reset), it takes the entirety of your software off the phone and puts a "fresh" copy on. You can then set up the phone as new and sign into iCloud or add your internet accounts to get your contacts etc. back.

If your battery is fine after that then you know that your software was causing the battery drain.

You can call AppleCare and ask them to run a battery diagnostics and don't be surprised when they tell you your battery is fine, because most likely software is causing your battery drain.

I can confirm this works because I had the same issue and tested this per advice from an Applecare advisor and turns out this was true. The last time I backed up my phone was months ago so it was nobody's fault but mine for not backing up information that I needed.

Hope this clarifies things!

I have the same issue! I'm on here for another reason (full bars for my Verizon LTE, but can't use internet off of WiFi), but my battery is drain way too fast. I had 70% battery when I left my house yesterday morning, I had iTunes playing, one app running background that tracks how long I've been walking, and was using an app to read. After 30 minutes the phone turned off. I didn't even get a 20% or 10% battery warning. Prior to the update I could have gone on a walk for hours with those 3 apps going and had no problems. So frustrating when something you spend so much money on isn't working properly.

Hi,

i installed the iOS 11.0.1 and first it seems a better performance in my iPhone 6S and APPs seems to run better without jumps. But the battery is still draining fast. I've reset the phone several times and also switched off... but it continues draining battery a lot of faster than in iOS 10.3.3. i think its running out the batt about 33% faster. I used to reach midnight with 6 screen hours and now its not capable to reach 4 hours and i've to charge in the afternoon using the phone normally without intense APP use.

I'm considering to downgrade to iOS 10.3.3. until a serious version of iOS comes.

I regret upgrading so fast to a X.0 version... it won't happen again.

This is barely aceptable... Mys iPhone 6s is always warm even without any application running, the iOS reset mentionned above doesn't improve the situation even a little bit.

iOS 11.0.1 doesn't change anything either.

I'm at work so I don't use my phone much, few calls, little gaming... it's noon and I'm at 29% despite a fully charged battery at 7 am.

I went into my settings, battery & waited until Battery Usage at the bottom of the page loaded up. It showed Siri had been using 44% of my battery & I don't even use it, so I turned Siri off & problem solved.

Same thing. Updated to 11.0.2 as a new iPhone and the battery drains really fast! I need to charge my iPhone two times/day and with iOS 10 I need to charge every 48 hours! My battery life is 89% checked today on Apple store.

I think that we need to wait more updates to improve the battery like iOS 10 works.

After complaining to Apple Support about the problem; they did a full remote diagnostic of my 5s... The result was that the phone and the battery were 100% OK. They said to call back in 48 hours if the problem persisted.

Amazingly my battery usage is back to normal with NO LAG in performance. I'm not sure what the tech did with the phone but it is now working fine...!

I got a total of 35 min this morning. Started at 100%. Had 'Walk for a Dog' tracking my walk, Spotify playing, and was looking over emails. I've tuned off iCloud for the photos since I backup on my laptop daily, so there is plenty of room to backup my other stuff since I was worried not having enough room on iCloud for backups was part of my problem since it kept trying. I have all of the location services 'off' or 'while using.' Siri is off, I never use it. I was down to 1%. Seems that anytime I use anything that is streaming it drains. I got about 40 min the other night when I was using Maps. I will likely just go stop by the Apple Store this week to have them look over it. This is ridiculous, I've only had the phone for about 17 months.

Same issue here, iPhone 6S Plus 128GB. Main repeated offender is when updating apps, I have seen 12% to 14% drain in 3 or 4 minutes updating 10 or 12 apps (800 MB to 1 GB). It happens every single time. Most intriguing is that in Battery info in Preferences the App Store doesn't even show as consuming much battery, I just updated 5 apps, lost 5% and App store use shows as 2% in the last 24hs. I haven't figured out if it is related to heavy read/write use or heavy wifi use that drains the battery so aggressively. The phones heats up a lot while updating apps, of course I mean much more than regular heating, and heats very quickly on the top right, so it's as if the updated daemon was running at 100% the whole time, and not only the processor was taxed but the read/write IO as well, I haven't seen battery drain this fast before even when using processor intensive tasks so it seems like a multi drain situation. It has happened in an exactly identical way just taking and looking at photos, 2 days ago I took some 10 pics in 3 or 4 mins, checked them in Photos app, edited only one for added saturation, a 1 minute edit job, by then I had lost around 30% battery. Of course the phone was probably trying to upload those photos too so again: processor + read/write + wifi?!? I've seen drain from 100% to 40% before I leave home, in around 1 hr time with only 10 minutes screen time. I have seen 5% to 7% drain only by opening Waze and choosing a destination, by the time it routes bam, lost that amount. And no need to say the phone was working just fine before iOS 11.

That's my diagnosis if it is of any help to someone, no solution, crossing fingers for a iOS update that silently solves this, soon!
