Iphone 6s Battery suddenly draining

It’s Safari. I’ve just watched my battery % drop in real time from 65 to 59% in a few minutes

That's what mine is doing. New battery 11 months ago. The advice from an Apple authorized dealer: Get a newer phone.

theres something wrong. With the 11.4 update i have a new battery and had no issues until i got the 11.4 notification is when all of asudden my phone starts lagging and freezing at 50% health. Battery is only at 19% wear. When i did the update it got worse and started at 60% health slow touch response and it even shut off on me couple times. Ive had my 6s for two years with n issues until two weeks ago.

I’ve just watched my 6S, less than 1.5 years old, drain from 78% to 65% in the space of 7 minutes. I don’t use iCloud backups and have Siri turned off as well as all the data sharing for “improvements”. I don’t have notifications running in the background for a load of social media as I’m not signed up to any of them and I have background app updates turned off for all individual apps as well as the global switch. Apple, you could at least be somewhat circumspect about your plan to get software updates to make older devices obsolete. Yes, thisbis following the latest update to 11.4. The saddest part, I know you, as a company, don’t really care.

Yes this. But just started suddenly today. Has there been a resolution? Its obviously a software issue. A battery doesn't just collapse like this. Its decreasing at 2% per minute with nothing happening.

I have an iPhone 6 and I keep it up-to-date all the time, I am not low on storage, and I always charge it like I am supposed to. The battery is a new one --I've had it for about a year-- it doesn't stay charged for long and it takes forever to fully charge. I can watch my battery drain without even touching my phone. It didn't start doing this until recently. I'm pretty sure this is all because of the new updates.

My battery is very weak

Has not been solved. I have resolved to have the battery replaced.

Have you just uploaded the new iOS ?

Since uploading iOS 12.1.2 on my wife's iPhone 6s and my iPhone 6 plus both phones are running out of battery within a few hours!

To make things even better, you might not even have to pay for that. I walked in and told them about my IPhone X battery draining fast and they gave me a brand new one free of charge. It was an iPhone X though so I don’t maybe.

I experience very similar issues. Yes, my iPhone 6 is old enough to be considered for battery replacement, but it's battery condition dropped suddenly last Sunday, with no apparent reason. Looks more like a software issue than hardware. I will probably end up with new iPhone this year, but it's not the point. Batteries don't die just like that.

Not Helpful. Replaced my battery 2 months ago. Beta says 99%. Was fine until about a week ago then all of a sudden the battery drains like a count down timer and even drains while plugged in and in use. tried various bricks and cables, still same issue. Only way to get it to charge is to leave alone and not use whatsoever.

So there is an app issue. And I have even been deleting apps, not adding, so it must be a native Apple app that is doing this. Guess this is how Apple gets us to upgrade, make the older phones so awful you need to spend the $1000 for a new one.

I’ve been having the same issue since yesterday. I’ve done all the things they tell you to do to conserve battery life but it still dropped over 20% in about 10 minutes. I’ve only had this phone (6S) for about a year and it says my battery health is at 95% so this shouldn’t be happening.

I noticed a similar thing and phone is less than six months old. It might have something to do with downloading office 365 with outlook which screwed up the laptop I'm not sure what it's doing to the iPhone. The battery loses power almost to shut off over six hour. Period.
