Something has definitively changed with my 6S battery life.

I've waited a week or so to see if the issue resolves itself. I don't know if it's an app or what because I've never really checked to see what was using what. Before I noticed the insane battery drainage I noticed my phone getting really hot while charging (once or twice about 7 days ago).

I think it might be Facebook but I'm not sure. All I know is that there is a huge difference in battery life. For 'last 7 days' Facebook says 7.1 hours in the background - again, I don't know if that's a lot, or what it normally is. Is anyone else having issues? I actually haven't tried deleting the app and re-installing it so I will try that now, but I'd like feedback if anyone is experiencing anything similar.

I work 12 hour shifts and occasionally check messages and notifications (1-2 minute sessions 4-5 times a day) and I've been anywhere from 60-40% by mid-day. In past I am in the 30s% when I go to bed around 10pm. This is quite perturbing.
 
Cant help, but I have a 6s, and its battery life is worst than my 3 year old(?) iPhone 5, which has been used to death and doesn't have a great battery anyway.

Apple, if you are reading, and thinking of making the next iPhone thinner so you can ditch the headphone socket, that will be one reason I won't be buying an apple again.

And if you make a thinner phone without bringing back battery life, that will be another.

Not very happy with my 6s battery life. There are 2 new ones in the household bought months apart and from different vendors, so the 6S battery life (in this house) has been confirmed as inferior to the iPhone 5.

phone or laptop, I prefer to buy whichever needs charging less often. Even if it means switching brand.

Like I said, sorry I can't help with your problem, I'd have to be using your phone, but good luck wit it. Search battery usage apps perhaps.

So what exactly changed? What are you seeing now (compared to before)?
 
Do you use Waze or Escort Radar's Escort Live! apps?

Why not remove the Facebook app and use the web page version on safari. If the battery life improve you found you culprit. Lots of people have reported Facebook as using radios in background, that can really eat up battery.

You don't even need to remove the Facebook app. Just fully close it out from the App Switcher once you're done using it. The Facebook app on my phone never causes battery issues or show up in the battery monitor with any obsurd background usage (not even 1 minute worth.)

Despite what many say or think, it's not ok to blindly leave every app in the App Switcher. Facebook being one of them, and I'm sure there are more that cause the same battery issues as well out of the over 1.5 million apps available.

Obviously incorrect. Because if you leave Facebook in the App Switcher it WILL continue to rack up background usage and drain your battery.

Re read what I wrote initially. Facebook app is known for this and is the top app to never leave in the Switcher. I can almost guarantee out of the over 1.5 million apps there are no doubt more out there that do the same that people never realize is happening. Using Facebook again as the prime example. So many people time and time again find abnormal battery drain and wonder why. They eventually discover (on their own or by someone else) the cause is Facebook.

Just closing it out from the App Switcher eliminates the whole issue without having to delete the app and use the website instead.

battery isn't to be bad with facebook like 13% used but now it's at 3%

IOS 9.3 is helping with this
 
The thing is this has all happened within a week. Something is very different/wrong and I need to figure it out. I was actually generous with my numbers in the OP. I'm in the 30%s by 1PM. It's quite frustrating.

Yes, if facebook app has Background App Refresh in Settings enabled (https://support.apple.com/en-us/HT202070):
Settings>Facebook>Settings>Background App Refresh

The Facebook app will continue to accumulate background activity regardless of if you have background refresh on or off. Did you not see the many threads about it all summer and fall? It's been proven many times.

I'm quite aware how iOS will suspend apps after some time. But as the Facebook app has proven time and time again, it's not always the case and I can guarantee it's likely not the only app on the App Store that can cause these issues.

Just keep an eye on the battery usage stat. For me, first I found that Facebook to be the problem. I uninstalled the app and just rely on the mobile website. But battery life is still short. So next problem is Safari. For some reason, since I have Safari iCloud syncing enabled, it keeps Safari active for some reason. Disabled that, and now battery life on my 6S is great.
 
i feel like just recently my 6s battery life has significantly dropped. At first I thought it was Apple Music. Now I wonder if it's 9.2.1 Nothing looks out of the ordinary in the battery usage stats but it feels so much worse. :(
 
I had a very similar occurrence with my 6s two weeks ago. Have you tried running the phone down until it dies? I hadn't done that for months and it basically sorted out my need to charge once or twice daily.

It also took me 3 hours of intense usage to go from 16% to dead, which meant it wasn't my battery, but the calibration.
 
I'll definitely give it a try. As you where, I'm charging twice a day....and my usage hasn't really changed. :confused:

I can only speak for myself but this isn't just a 'drop' in battery life. I'm certain that anyone with my phone would feel the same. Today I tried turning on low-power mode at 100% and by 1PM I was, again, in the 30%s. I even deleted the Facebook app, with no changes. The %s in settings seem all over the place, inaccurate, and they change. Now messages is saying 25% usage and I've sent maybe 6 texts.

Also, try turning off Safari syncing under your iCloud settings.
