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.

I have just replaced my iPhone 6 battery with a new OEM battery and still have the same issue. I restored my phone back to factory default and I cant even get 4 hours from my battery. (At least its getting good cycling). I have tried everything and yet nothing has even slowed the drain down (even with just restored like new) phone.


When is Apple going to fix this issue or at least provide a link to enable the affected users to re-install IOS10. Have you had any luck or responses yet?


I am now at my wits end and am considering going to a supermarket and buying a cheap smart phone for around $150 (aus).


If you are going to take advantage of the new battery read the fine print very carefully as you mat not be able to take advantage of it.


Is anyone having the same problem on Iphone 7 or 8?

Hi Dylan,


It would seem that the battery on your phone is draining way faster that it was. I would suggest that you might as well check the activities you have on the phone because there may be a lot of things that causes the battery to drain faster. You can check the usage on your battery on this article : About the battery usage on your iPhone, iPad, and iPod touch - Apple Support


If you checked and it seems that there are apps that gives you quite a problem then kindly reduce the usage and that will help the battery to last more longer.


Also you might as well check some settings that can drain the battery faster e.g. Background refresh app, Auto-rotate, Brightness etc.
