Thx to all, and mostly Magnumct

Same here, just updated to 11.2.5 and my battery went from 80 to 40% within one hour! Apple needs to provide a fix. After knowing all of you have had the same battery draining issue, Apple should have trashed this update so nobody else would be affected. Maddening!

@MichelPM I don't understand why you keep suggesting to people to go and get a new battery? All these batteries where just fine a few days ago before update 11.2.5, isn't that enough to make you understand that 11.2.5 is the problem? I have an iphone 5s but i bought it new 4 months ago so my battery is fine since the battery of my last iphone 4s lasted me more than 3 years..

If you purchased a iPhone 5S 4 months, ago, as new, you probably purchased a new "old” stock device as the iPhone 5S was discontinued in March 2016!

So, the battery in that phone, could be, at least, almost 2 years old!

You have no idea how old the battery is in that iPhone 5S.

Get your iPhone 5S battery checked out!

Ok, seems you have found a universal response to any iPhone 7-or-older owner. But what do you think about my situation? As I mentioned before, I have a shiny brand new iPhone 8, that I bought 2 weeks ago from authorized reseller. Which means that this phone’s battery is new. It was also confirmed by Apple support during remote test. Everything works as it should they said. Yet nobody knows why I’m experiencing the same problems as other guys with the older models after 11.2.5 installation. Any fresh ideas will be much appreciated! Thanks in advance!

I have an iPhone 6. I have similar experience to the list of people saying the same thing about the update and battery loss. Until the last 5 updates, I have loved my iPhone even with the glitches that came with the 6 phone. Your answer provides the standard ways to save battery power but you did not address the update change and its relation to the wide spread issue of significant loss of battery life. It certainly appears that it has happened to many immediately after the update. Additionally, the speed of the phone operation has been dramatically reduced. This goes back to one of the more recent updates where Apple admitted it was slowing down phones to save battery. And a list of other issues (seemingly from updates) that makes a product that I absolutely loved to one now where I am ready to switch to a non-Apple product. Is there a fix or is this the norm until another update comes.

My wife and I are using 1-month old iPhone SE models (32 GBs models) that have been updated to the latest iOS 11 version and neither of us are experiencing any of these battery draining issues!

NONE!!

What is your explanation for that? Hmmm???...

I see you are being very persistent that we need to buy a new battery(!), even though the batteries were working just fine before the 11.2.5 update....before I decide to BUY(?) a new battery, can you at least admit that if Apple didn't offer/encourage the update, and/or IF we poor souls had chosen NOT to install the battery draining update, our batteries would not have had this sudden accelerated drain problem? I don't see the $29 battery offer in the links you have sent. We shouldn't have to jump through more hoops to find it. From the time the first forum contributor described the battery draining problem, Apple knew there was a problem, and they should have immediately sent an alert to all iphone users letting us know the update was going to drain their batteries and provide the link to a new FREE battery. Thanks for listening.

Well, first of all let me specially stress out that answering in a “question on a question” manner is acceptable only if any additional clarifications are needed, otherwise it is unconstructive and does not lead us anywhere. I’m happy to hear that your and your wife’s devices shows the expected battery life and do not suffer from the described issues. Let’s consider this as a possibility of normal functioning of such type of devises. It is just led for us to find how it is possible to solve our cases and make our phones work great (again). Thank you!

İphone 8 alalı 1 hafta olmadı şarj çok çabuk bitiyor 11.2.5 battery problem problem problem 800€ para verdik günde 3 kere şarja takıyoruz ayıp hemen çözülsün durum bir an önce siz Apple sınız kendinize gelin !

Same problem here. I have an iPhone 6s and am noticing immense battery drain with latest update. By mid-day I'm at 20% without having had one conversation on the phone (and only having sent one or two texts). Minimal web and streaming usage as well. My 6s is less than 2 months old, so I know the drain is not due to an aged battery or phone. It is 100% response to the latest update. Colossal aggravation, but not surprising given Apple's recent track record. A solve would be appreciated.

Ditto! I’m seriously sick of it. Battery life had been awful from the minute I updated and phoneover hearing. I could use my phone at work all day and have 30% left. This morning I unplugged my phone at 100% drive 15 minutes to work and hadn’t used it and it was on 83%. App has lost the plot!

I purchased a new battery for my iPhone 6s two weeks ago after updating to 11.2.5. This did not solve the problem of the immense battery drain my phone is having! So, I assumed that maybe I received a bad battery and had it replaced again. This again did not solve the problem! I have been following this thread since the beginning and have tried all solutions presented. My phone battery continues to drain extremely fast. By noon each day I’m at about 20% after starting at 7:00 a.m. with 100%. This is without using the phone except for sending a few texts. I don’t know what else to do at this point. I can’t have an unreliable phone.

I have an iPhone 6 and experienced the same battery drain. My phone went from staying charged for over 24 hours with normal use to having the battery drain to zero in only a few hours after the last update. ( and that's with all apps closed except for mail and messages )

I tried the the fix mentioned in previous posts of turning off iCloud Drive - it seems to work! My battery percentage has gone down 5% in an hour compared to about 1% a minute before the fix.

I have tried turning off iCloud Drive and didn’t see any significant changes. I think I’ve turned off about everything! Nothing so far has helped slow the battery drain. I’ll keep trying! Thanks!

Was wondering if Apple has acknowledged that this is a real problem. Or, if there is a fix on the way.
