iPhone 6 battery suddenly draining fast

My wife also had the same problem on her iPhone 6 two months ago. Same steps, we turned off background apps and shut off bluetooth and so on and so forth. All the troubleshooting steps Apple mentions online. Which by the way don't make sense because the phone went from working perfectly to all the sudden not being able to hold a charge almost overnight. My wife is not a power user either and has very few apps she actually uses. Anyway I took it to the Apple store and waited in line for a couple of hours and at that point insisted that they replace the battery even if I had to pay full price for the repair which was around a hundred bucks. For me I'd rather pay the 100 bucks to make the problem go away than have to spend half a day standing in line at a crowded Apple store. Anyway, that worked and she hasn't had a problem since.

Also a new map feature showed up recently, or I just started noticing it, 'Show parked location' where the phone is now periodically popping up a notification saying it saved the location of my car. My opinion, there must be some power consuming process running in the background that monitors my phone and decides that I have been in my car and parked it so it can save my location and show me a notification. I turned that off using the switch in the 'Maps' settings window. Will see if that makes a difference. Has anyone else noticed this feature? Is it new or I just didn't notice it before?

All finally I changed the batter for 100$ and waiting to see if the problem solved?

Also contacted the Apple support. They tried the battery test and it was fine. Told me to try Apple information on battery usage for two days (https://support.apple.com/it-it/ht201264)...of course they know it's not useful.

Anyway, the girl i talked to said it's something about the software and that they're receiving many similar complaining. Then she said if it didn't work to call them back with another phone and a computer with iTunes turned on (and previously making a backup of the iPhone). That way they will do other tests. I'll call tomorrow and let you know.

I have the same problem.

On my phone, I think turning off 'show parked location' and then rebooting the phone has seemed to resolve my particular issue. My conclusion is of course completely un-scientific. I have no real data that shows that is the problem and there are thousands of things happening on an iPhone at any given second. But, there you go. Something to try at least.

What is the solution? Going back to a more reliable phone. Paying too much for the phone to crap on me now.

Too much for a battery. Good luck.

Has this issue been fixed yet? I had the same thing yesterday, they had me do a restore iphone and it still isnt working.

Did changing the battery work? Thats my next step, but don't want to spend the money if it won't work.

I just noticed the exact same symptoms you all describe. This seems likely to be a software problem since my issues started after the iOS 10 upgrade and it seems unlikely all of our batteries are suffering from the exact same issue. I was going to buy a new phone but I'm going to hold out until this issue is resolved. If I do have to move on it will be to an Android. If anyone finds resolution please chime in.

My phone is doing the same thing. IPhone 6 goes from 42% to 7% within 5 minutes. Plug it in and minutes later it jumps to over 56%. Come on Apple get a fix for us iPhone 6 users please.

I figured this was a fairly universal issue, especially with older Iphones. I have the 6. Since ios 10, I'm getting the same nonsense performance from my battery. It dies with 40%, 50%, 27%. When I plug it in it shows that I still have the aforementioned batt life remaining. This is an iOs problem, plain and simple. I love Apple products, but Apple Arrogance, Dishonesty, and Indifference are pushing me away. Why don't they just tell us that, if we want "Apple" performance we have to buy the newest iphone, or tell us we can't have the ios updates since they either don't test for back model compatibility or know it's going to cause a problem and don't care, since it will send some to the Apple store to buy the newest phone sporting the usual incrementally minute upgrades. Don't insult us by asking if we've done a hard reboot or restore when you know that won't work. That's condescending in the same way that it is when your mom asks you if you looked in your closet when you can't find your shoes. She doesn't care if you find your shoes, she just wants you to go look somewhere else. You will eventually kill the Legacy Steve Jobs built with your gross indifference to customer service. It's really cute that I can send a text message with floating balloons, but my balloon generating device is also a critical lifeline for my income; the income I use to feed my family, to clothe my kids, and buy Apple products.

After I spent 75£ for new battery it is goo so far. It's only a week. Let's me see few more weeks before I recommend anyone.

How do you reach"show parked location"?

Today it happened again, always around 30%. I finally called back Apple Care. The guy who i talked with admitted they're receiving complaints from different users about this problem, also with no 6s iPhones (mine is 6). Since i installed the 10.2 two days ago restoring the iPhone from an older backup, he didn't ask me to do that again. He said to use the phone still for a few days and note every time the problem persists, the exact moment and what i was doing. Then i'll call him back and he will check the diagnostic of my iPhone looking for those errors, then send them to a technical department...i'll let you know
