iPhone 6 battery suddenly draining fast

I've had my iPhone 6 since the end of October 2015. Everything has been great, until recently. Suddenly, my battery drains A LOT faster than usual. I never let the percentage get below 50%, and I don't have many apps, the brightness is always halfway, and it's on DND overnight. I have AppleCare, but would they replace the battery or would I have to buy a new phone through applecare? Thanks.

my phone is doing this too!

My battery dies less than an hour after full charge to 100% and takes giant leaps forward toward death. For example, battery charged fully overnight, battery meter at 100%, I send a text message, 10 minutes later 80%, make a 5 minute phone call, down to 50%, then scroll the internet for 5 seconds and the "battery power less than 20%, low power mode" option pops up, then i hit ok to choose low power mode and it goes to 1% before my eyes instantly. I plug it in and immediately back to maybe 50%! i'm gonna post this separately to see if maybe there are new responses.

"The problem is a software issues that they have not found a solution to."

Did an Apple rep actually admit to that? Can you provide more information about that part of the conversation? This is such a big and controversial issue, a LOT of people here would be interested in that.


p.s. I'm assuming that you are running IOS11.0.something....No guarantee but you might want to try IOS 11.1 just released yesterday.

I have an iPhone 6. It has worked fine until the past month or so. Recently it'll drop from near fully charged to saying the battery is fully drained in a very short period of time. On Nov. 12, it went for fully charged to saying it was fully drained it about 20 minutes. However, I don't think the battery was actually fully drained. I believe this because when I plugged the phone in, within a few minutes it said it was >90% charged. Something is seriously wrong here. It sounds like a software issue to me, but maybe it is also related to the battery. I noticed that this is most likely to happen when I'm switching from one app to another one. Like today, it did this when I had the Overcast podcast up open and running and then when I switched to the photo app and back to Overcast it crashed and said the battery was fully drained. Maybe it has something to do with one of these apps or with how switching between apps is treated.

Since I've updated my iPhone6 to IOS11, my battery has been running down faster than normal.

I have done these things to try and extend the battery life. Whether it was because of one particular thing, a combination of a some or doing all of them, my battery is now functioning normally.

- turned off background app refresh

- turned off as many notifications as possible

- turned screen brightness to half

- set Auto Lock to 1 minute

- turned Siri off

- use home wifi

- turned off iCloud (only use it for Photo Stream)

- Bluetooth is off when I'm not using it

- when I charge, I only charge to 80%

I also did some other things mentioned in the link below. I don't know whether it was one particular action I took or a combination of some or doing all of them but my iPhone's battery now lasts the same as it did prior to updating to 11.

I have the same issue! Only recently, I started having the problem with my iPhone 6s since with updated to iOS 11. I started with 30% and in less than 5mins down to 15%. Sometimes it stops there, others I have to soft reset or keep turns off for a couple of minutes in order to stop draining. Happens a few times already and Apple support suggested me to to backup everything and do factory reset. I still yet to try this out. But very annoying!

Hi everyone,


I'm having the exact same issue. I've run all the updates as Apple Support suggested. They ran a diagnostic on my phone and it passed with flying colours. They then suggested that I "optimize" my battery usage by playing with the settings, and then suggested that I reset and erase my phone and to set it up as a new phone.


A couple weeks after wiping all my information and setting my phone back up the issue has come back. Sudden battery drains and now the screen freezing issue due to temperature changes and my phone is completely unreliable. This was a great phone before the IOS 11 update, what is Apple doing here?


I DEFINITELY believe that this is purely a software issue!

I find it strange that no-one from Apple is responding to any of these concerns, don't they read these messages?

I found a support website set up by a guy that used to work for Apple and he seems to know what he's talking about.

I would suggest following his suggestions and if your battery problem is still not fixed then you will need to go to an Apple store and get it tested.

Here is the link: https://www.payetteforward.com/why-does-my-iphone-battery-die-so-fast-heres-the- real-fix/

I just followed his instructions and will see how it works, everything he suggests is reversible so it's worth trying.

Good luck!

If the battery drains down to single digits, then your battery is good.

Normally in a high drain situation if the phone turns off while levels are 30-70% it is indicative of a battery in need of replacement.

My battery was dropping down to 66% and then the phone would turn off. Putting it on the charger, as soon as the low battery changed to the Apple screen came up the battery was at 66%. Replacing the battery it now drains to 1%, and when plugged in comes up at 3%.

Got the exact same problem !!

Battery drains down to fast and when plugged it jumps to 40 %!!

I have recently heard that Apple is intentionally doing that to force their users to upgrade to newer versions of iphone, becuase as I actually heard that it only happens to phones with ios 10 and higher making things pretty obvious !

If someone has tried sth like going back to older ios or sth like that, plz tell us !!!
