Iphone iOS 8.1.2 battery drain remains

Hi!


As I have been seeking for a solution to my iPhone 5s battery drain problem after iOS 8 install, I have to note that today, after all of the updates the battery life remains non existent.

Battery drain in only half a day without light use, everything turned off, and not a single app installed. And the most surprising part that battery drains overnight, without use, on a airplane mode.


In the battery usage window the things I see:


  1. 65 % Phone (low signal)
  2. 17 % Home & Lock Screen
  3. 14 % Settings
  4. 4 % Messages


What has been done?

  • Did many fresh installs of software from update (itunes and iCloud)
  • Fresh install setting as new phone
  • Fresh install, setting as a new phone and creating new apple id;
  • Settings are set up to save every percent of the battery (including no WIFI, and no cellular data). So at this point my iphone is just a phone to ring.


Did not see any improvement over the updates iOS 8.0.2, iOS 8.1.1


I would be so appreciative for your further support in solving this question.

This is so true.

I completely lost my faith in finding a solution in the setting or modifying behaviour - the phone still does not hold any charge. So my solution is to wait for another rumoured iOS 8.1.3 update and hope it will fix this drawback.


Until then, the phone is not usable - 5 hours of iphone work with low activity is not acceptable, am I right?

I waited a bit to update to 8.1.2. Apparently not long enough. 5s/64GB. Same issue: never had a problem with the battery draining before. Now, it is sucked dry...down to 36%...from 100% overnight...with all apps closed and no use. I have to check it all the time now. I guess I'll just tether it from now on--carry the charger with me. So much for convenience and mobility. Reminds me of the phones years ago that were plugged in the wall--I thought we got rid of the cords! Ridiculous.

I found a solution.....went to my local mobile operator who sold me the phone, still under warranty they replaced it with a new phone. So without admitting there is something wrong they simply replaced it. Now without even opening it, iam putting it for sale on ebay, and i already bought a new iphone 6 plus


...this time i will not do the mistake of upgrading to a new ios before researching well.


Now ios looks more like android than a closed well guarded garden, very unstable and very buggy.


my recommendation is dont wait for next upgrade, try replace it with apple

I bought an iphone 6 plus, because it should have great battery life. But what do I get? Trash. I am surfing the web for 1-2 minutes with cellular and I loose 1% for every or every second minute. Thats with 8.1.1. I updated to 8.1.2 and nothing changes. People were talking about at least about 10 hours battery life with heavy use. I dont even get 7 with light use and everything turned off! I have to worry about getting through the hole day with the 6 plus. Thats inacceptable. Apple you have to change that or I gotta change my phone

On my iPhone 6 Plus here and I'm noticing a battery drain. I have 8.1.2 installed. I believe 8.1.2 is at fault here. Actually I had a great battery life when I was at 8.0 but each update, battery life gets worse and worse on each update from what I have experienced. No my battery is not defective because it's reading at 3000 MAH.


I used to get about 45 minutes of usage before it drops from 100% to 99% and now I only get about 30 minutes of usage or less then in drops to 99%. This is very annoying because I'm used to the 45 minute usage before it drops. I've even gone as far as factory restore and setting up as "New" and still does it. I think Apple Pay is culprit here too because prior to adding my card, I can get about 45 minutes, but after adding my card to apple pay it is random.

Just for the records and for the sake of Apple knowing it: same problem here.

Iphone 5s 64Gb.

Battery used to last 2 days on iOS 7

On iOS8 I'm on a day and sometimes I cannot reach the end of the day; same use.


I'd say that however iOS 8 looks nice, the updates are definitely not worth the halving of my battery life.

OK guys.

BIG news on the problem we are having together.


A little pre-story first. I could not handle having the phone and having to be careful walking out of home and not having connection. I was so tired of this unnecessary problem!

So i started using my old iphone 4, which remarcably holds power for 48 h. But last night I came to a conclusion that the update of 8.1.3 we are so eager to get might not be that soon as i thought (I was expecting it on January 6th), so i decided to get iOS 8.2 beta 3.

The decision was made due to the idea in another forum, that someone had the same issue which disappeared after installing that particular beta. So I did it too.


The result is THE SAME. I can not hold my words anymore. What the ****?!


And this rises so many questions like whether this problem will consist in the future updates?

I'm not sure about you but I seem to have found an issue with the battery drain on iOS 8.1.2 (but I'm on 6 Plus). Anyways I'm on AT&T Network and at recently they have released the carrier update setting to 18.1 (supposedly it's for VOLTE). Anyways I found that with 18.1 carrier update setting, I noticed that my battery would drain even without touching it, heck with only 30 minutes of usage, it would go down from 100% to 99%. Frustrated I was, search Carrier update settings 18.1 and found that this was the issue (I believe only the 6 and 6 Plus received this update).


So I decided to do a factory reset and set it up new and to ignore the carrier update settings 18.1 and remain on 18.0. So far it has fixed my battery drain on my 6 Plus and is back to normal. I would go from 100% to 99% in just 45 minutes of usage (which has always been the case). I'm thinking that 18.1 carrier setting is at fault here. But if iOS 8.2 releases with Carrier 18.1 then I'm sure I'll be experiencing the drain again. But knows, it may not be the 18.1 and might be something else.
