Sudden battery drain, not iOS 9.2, resolved

A few days ago, my battery suddenly began to fast drainage. Classic symptom: in settings/battery standby time was equal to its use. (see: http://appinstructor.com/blog/2014/the-ultimate-guide-to-solving-ios-battery-dra to). It was not caused by 9.2, because it was almost a week after the installation of 9.2. Here are the troubleshooting steps I followed:

  • Reset by pressing the HOME and SLEEP until the Apple logo appears – not solved
  • Killed all the apps after double-tapping the HOME button, then reset as above - not solved
  • Off push email - unresolved
  • Settings/battery tested; the best app was calendar, 78% of the use of the battery - this reduces the search
  • Knowing that an MS Exchange account can sometimes exhaust the heavy battery, I deleted my Exchange account and the reset - not solved
  • Additional hint: in OS X Activity Monitor on my Mac the application calendar used huge amounts of data - beyond 1 GB transfer
  • The only other source of calendar events was iCloud, so I turned off iCloud calendar and back again - battery drain stopped
  • Added my Exchange account back - no extra battery drain
  • If the problem was related to iCloud contacts. On a hunch, I left iCloud calendar off all night. When I turned it on once again the battery drain has not returned - problem solved.
  • The use of heavy data in Mac OS X stopped when I turned off iCloud calendar.

While I can't explain why it worked, I can speculate that there is data corruption in the Calendar database, which was somehow fixed by leaving it turned off for a period of time.

Thank you Laurent this added to my favorites.

    When update you? Using it more than usual? I suggest let it drain until it stops completely and then let it load to 100% once, so the battery can be recalibrated on the new OS. Which also has repercussions are research Spotlight etc., which are indexing on your phone after the update.

    Also, try to use low power mode in the settings.

  • With ios10 battery drain

    My battery drains with ios 10. As soon as I installed, I noticed that the drain was immediate. As in 6 hours, it was almost 25%.

    I read in the posts to go to the battery in settings to see what is causing the drain and she is running in the background at 59% of the agenda was 10% of Messages. Which cannot be turned off like a support staff told to do. Go to the background refresh and disable the application. Of Messages is not in the list of apps to go out, then it will not work in the background he.

    It's terrible this new ios with messages. I wish that I could turn it off or return to ios9.

    I hope that Apple will correct it soon. I searched Google too and it is everywhere in line with with ios 10 battery drain.
    There is hope that they do something about this. This is only my second iphone and loved until this.

    Well, I hope this problem is solved!

    Restore your device to the factory settings and set in place like new.  That will probably be your battery problem.

  • iPhone 6 iOS 10 massive battery drain

    Use iOS 10 since beta. Around Beta 5 or 6 noticed my iPhone 6 suddenly started battery drains very quickly and also began the statement incorrect autonomy (jumping massive amounts of %).

    Continued on the public (10.0.1). version I know that it's a software problem, because three other people I know with iPhone 6 have exactly the same problem with iOS 10. I've seen others suggesting that it is "normal behavior" which occurs because Spotlight indexing / App updates etc. It is not true that I was see this behavior for weeks now since the middle of the period beta.

    I already tried to wipe the phone completely (do not restore from backup), and it has changed nothing. Is there a solution or is my only option to try to downgrade to 9.3.5 until a new version of 10 is available that will hopefully solve the problem?

    Did someone at Apple aware of this problem? I saw many many posts on these communities with my exact problem.

  • Battery drain / ability / sudden stop (iPhone 6-6 s)

    My battery keeps showing different levels of load. He jumps abruptly from 29% to 1% in the blink of an eye and then stay at that level for half an hour (even by playing on its maximum intensity youtube videos)

    In my view, this is a software error and the battery is actually OK? Any ideas what this problem is called 'officially '?

    My research:

    I've been following and looking for the solution of this problem for over a year now (6 cans cut randomly with the left battery iphone or Re: IOS 9.2 fast battery draining issue for example)

    On another recent thread, I've seen the trick to five (free App) battery life a try and I also did a "recalibration" procedure, which I found at http://www.appledystopia.com/how-to/calibrate-iphone-battery/

    My findings with screenshots of battery life

    (1) 19:48 - evening left power capacity of just 855mAh and 0% (or 1%)

    Youtube videos, I played for a while, but it is not stopped by himself for a while. After that it became finally black:

    (2) load with my official charger + cable provided with the iPhone 6: phone instantly displays the Apple logo and boots. It climbs to 6% (and the ability of 1094) instantly

    (3) morning after full load

    Capacity remained more or less the same (now at 100% load)

    04:04 hours and used light (surf) during a phone call, capacity is up to 1167mAh in charge of the battery fell to 58/61%

    (5) after that the phone went to about 30%, and I've done a partial recharge in the afternoon. I don't remember follow the battery and when I stopped to load (somewhere in the 80-90%) The power was now back to 1412mAh

    What happens here? Can anyone help me debug this. Is this just a broken battery?

    Note: This is with an iPhone 6 but I had similar problems with an iPhone 6s. Both use the leather of Apple to the official address case. The problem with sudden closures has been particularly bad in winter btw.

    If someone else should find it, here's the solution I came up with that

    After two years (without any warranty and AppleCare more) the battery was at 589 load cycles

    Search online for "iPhone 6 battery replacement walter Galán" I found a guide and a battery of spare + parts

    After 45 minutes of work, that's what I ended up with: a perfectly working again iPhone:

    I hope this helps. I suspect still hot/cold broke my battery (perhaps in combination with a power draining the CPU at a certain point, improvements iOs 9). Anyway, the new battery has been behaving perfectly for the last 2 weeks...

  • iOS 10.0.2 battery drain

    guys, I'm using iphone 5 s for 2 years. my battery life is good. If I SLEEP at night and wake up my phone just reduce by 2-4%... since I updated ios 10.0.2 my battery draining fast. nearly 60% increased after more... Battery all day draining even if I don't use anything. If I turned off my cell data also gives me same result.

    I use ios 10.0.1 before still going strong with no problems of drainage. Can someone give me a solution...

    Your help is very appreciated.

    Try the settings > battery to see what is using that a lot of the battery.  Maybe it's something you can disable when not in service.

  • ioS battery draining / overheating

    I use a 6 16 GB iPhone on which I downloaded iOS 10 a few days ago. I hate this update! The drops of the battery to 100% less than 30 percent in less than two hours of use; and that, no phone call - just by using whatsapp and twitter. I also had days where the battery shows 23% and now after the phone dies. When you connect it to the power supply, it appears directly at 21%.

    In addition, to use the phone for about 30 to 40 minutes in a row, it heats considerably, something that was not the case before.

    If there is a way to solve this problem, please tell. Or Apple must come with a fix emergency. It's a pain to have to keep the phone attached to a power Bank.

    Hello

    Unfortunately, this is a very common on more problem iOS 10 users.

    Here is the link to another discussion: iOS 10 battery draining / overheating

    Hope Apple will deliver a fix very soon.

  • iPhone 6 s massive battery drain iOS 9.3.2

    After upgrading my iPhone iOS 9.3.2,and 6s I feel huge battery drain. Day before the update, my battery was normal. Usually I lose 30% of 08:00 to 14:00.

    Now, after unplugging for 5 minutes, I'm 95% after 3 hours 59% etc.

    I tried to set up as new iPhone, installed the new OS with iTunes, but no change.

    Off location, off automatic backlight, the signal of the complete network.

    What should do? It is obviously a huge problem, because I can't rely on my phone.

    I've updated my 6 Plus and have not noticed any radical change on the battery life, good or bad. What you have all services like location, mobile data, updating in the background app, Bluetooth, etc. put on the market and it is what causes the battery?
