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.

having the same issue on my iPhone 6 10.1.1, battery drains too fast and keeps fluctuating when I plug and unplug the phone, on standby mode overnight it drains like 50-60 % and nothing is even happening on the phone, very frustrating, apple needs to address that issue and quick, I thought my battery gone bad but now I see that a lot of people are having the same issue

I also had the same battery issues of rapid draining and then instantly jumping when it was plugged in. I tried force quitting apps, restricting notifications etc and rebooting but nothing worked. Today I called Apple and the rep did a diagnosis over the phone. He couldn't find anything wrong but decided that we should do a restore. He walked me through the backup procedure and helped restore the phone. It worked! Apple called me back 4 hours later and will call back again tomorrow to check if the battery issues have come back. Everything seems to be good but I've got my fingers crossed.

My iPhone 6 has also been draining very fast. I also get random jumps in percentages when plugging it in. I will plug it in and it will go from 10% to 42% immediately. Also, I've seen it go from 29% to 1% within 2 minutes. I have a regular old 6 (not a 6s), that 6s recall should apply to the regular 6 as well. There are a lot of 6 users experiencing the same exact issues that 6s users are.


Of course, this problem with the battery starts up just a day or two after my applecare+ warranty expired. 😟

Same issue. Random battery drainage with in minutes of being fully charged. No consistency to the activities being done on the phone. We have done everything Apple has suggested. Shocked, dissapointed and ready to stop using Apple! Stand behind your product Apple! You demand premium prices. We should get premium product!!!!


Between Tablets, Phones and Laptops we own 8 Apple devices. This is enough to say "I am done"

Same thing happened to me today — I got the 1% battery warning, even though I had charged it a few hours before. Sure enough, the battery jumped right back up to 65% when I plugged it in. I wasn't even using my phone right before the battery drain, it was just in lock mode on the table while I was doing other things around the house. I've had my iPhone 6 for 2 years and never had problems before updating to ios 10. Strangely, my phone decided to restart itself overnight and I woke up to the white 'Hello' start up screen this morning. I have no idea if that's related or just another thing going wrong. I just turned off the 'Show Parked Location' as some people suggested. I'm hesitant to resort to restoring my phone or replacing the battery, but we'll see if this problem persists....

I just replaced my battery in my iPhone 6 and it is now performing normally. I think that a lot of iPhone 6 batteries out in the wild are reaching the end of their life, and newer iOS updates are using up more battery life and exacerbating an already failing battery.


Go to ifixit.com and look up how to change the battery out, it's actually easier than it looks and cheap. It's what I did, and my phone's battery is back to 100% capacity. You can go to amazon.com and get similar repair kits for even cheaper.
