Hello everyone. I'm from the Russian community 4pda. On our iPhone 5s 1457 after upgrading to 8.1.2 tnablyudaetsya sillny battery consumption. Battery life time is equal to the active use of statistics. Phone lain all night after a full charge and disappeared 20% of the battery, the statistics indicated that 6 hours is used. On 8.1.1 was no such problem. I have a new battery has 300 charge cycles. The problem occurs if the device to flash through the DFU mode.

According to the recommendations disabled icloud on the phone - the problem is relevant.

Check this out:


Fully recovered by IPSW (clean install), took out the SIM card,

no siri, no location, nothing, aeroplane mode ON (so no wifi, bluetooth...etc)


I left the phone on my desk for less than 14 hours, didn't use it at all (as shown in the usage figure),


LOOK! 55% of the battery gone! Something is really WRONG with the 8.1.2 system!

"I try to help others here." <- You didn't, at least not in this post, check all 4 pages, who did you help? Nobody.


"This forum is for technical questions, not for people to rant and rave about what's wrong with Apple." <-You assumed everyone could ask questions in a "techincal way" here? Come on, not everybody is an engineer and could ask questions in your preferred way. We are not ranting, we are posting the symptoms that we are having for the real technical people to find out the reasons behind. Just like when we are sick and go to a clinic, we tell doctor the symptoms we are having and not speaking in a technical way, it's for the doctor to further diagnose what's wrong and to come up with a suitable treatment.


You're not really helping Apple here, in fact you're bringing their image down by your strong denial to facts.

After thousands of replies maybe it's time to review your way to "help others here".


Which phone I got to replace the 5S doesn't matter, what matters is Apple should fix this battery drainage problem as soon as possible.

I received an email from Apple with a link to run the diagnostics tests, that's technical and help. "We are here to help."

That's a proper attitude and I like Apple the way they handle issues.

WWhat the **** is going on with my **** phone! I'm so ****** with this brand at this point. Seems to me this is more like sabotage. applea releases new update to crash all prior phones to get new revenue. Well screw that! I paid for my phone and I shouldn't have to worry about "NEW" updates screwing up my lifestyle. Thesea updates are suppose to improve ones confidence in the product not destroy all hopes or wants within. Apple your totally screwing yourselves over.


Perhaps you'd like to post this rant someplace where Apple will read it? This is a user-to-user technical support forum. Apple doesn't review these forums for customer feedback.

hey! =D

I made a phew steps before this test:

  1. reset all the network
  2. restore with backup
  3. restore as a new device


After that procedures (I made that in one week, so after 7 days) apple sent me an test by e-mail (another user shared the screen), to see if there was something wrong with the battery, and it returned no issue. So, with all that properly reported to apple (since the first contact, they may send you an number for the case), I was able to have no other choice but take the device to a genius bar - And I think it's very important to make it all clear about the warranty: the attendant confirmed me that there is something wrong with the device, and they are not able to solve by chat or phone.


Unfortunately, for the holidays, I am away from home. I promise you that I will post here their solution for this problem after taking it for the genius bar.

If there is as you say a confirmed hardware problem then there's nothing any of us here can do for you. We can only offer a limited number of steps for you to try. When all that fails you take the device to Apple. That's all there is to it.

Yikes! iPhone 5s 32GB about 13 months old. Killing my battery but only after iOS 8.1.2 update!


This morning dropped 39% after 5 very short messages, no photos or attachments. I checked Usage and it shows Messaging at 36% and everything else at nearly nothing but the Home & Lock Screen at 11%. 372 charge cycles and battery life fine prior to this update being pushed.


Phone has been optimized for battery life with all legit battery saving tips applied.


Something's up!


Hope this can be rectified before too long . . .

Hi Jaberboss


I did start a similar thread on this issue myself, but seeing what I've read here I hope you're ok with me adding it here to


This one is a true case of a phone with zero potentail (electrically)


OK, I've done the rounds on this one, whereby I'm just adding to the list of complaints so that (hopefully) the powers that be, or not, in my phones case, might listen.


Since updating my just over 12 month old 5s to 8.1.2, it has turned into a bag of spanners in respect of its battery life. Its literally gone from 24 or so hours between charges to less than 8 !!


I have tried shutting all the apps down and even had it sitting in full airplane mode, where i've left it alone with the screen off, yet its dropping around 1% every 3 to 4 minutes, blinding!! Checked battery usage in settings after 30 minutes, guess what standby 29 minutes usage 1 minute.


Also tried the full restore, but to no avail, still a bag of spanners!


(slight update here) Even took the SIM out with it in airplane mode and deleted all apps and a full reboot - same thing!


Does anyone remember the good old days of a fixed land line, where the phone had to be plugged into the wall before you could actually use it? lol


Nothing like a bit of retro ay, but some how I cant see this one catching on Mr Apple. Thanks

Guys, the same here. I've just upgraded to iOS 8.2.1 and the battery last just for 4 hours. Some blogs have the same opinion, and sometimes they recommend to turn off some atributes in order to save battery, but... come on, I would not buy a product which I have to cut its resources in half in order to save battery. It just happened after the upgrade. Apple is getting closer and closer to vanish from my life.

If you want all the options On then yes it'll consume more power, just like leaving all the lights and appliances on in your home. Want to save some power in your home? Turn off some of the lights and appliances. Want to save some power on the phone? Turn off some of the options.
