The battery life doesn't look that bad if it is mostly screen on usage. If you have had your screen on for most of the 4+ hours, then that's why the battery is low. If most of that usage is screen off usage, then something is definitely up with Facebook. If you haven't, then I'd try deleting facebook and reinstalling. I wish apple would show screen-on time.

Verizon, in my area, doesn't have the densest network and was always hanging onto weak 1X and LTE signals which never helped my battery. LTE signals with high "noise" (aka RSRQ) would absolutely destroy my battery as well as cause very slow speeds. Perhaps the network changed somehow and if you are getting terrible RSRQ (no good way to measure this on an iPhone unfortunately), that could absolutely be the cause.

The screen was off for a good chunk of those 4 hours. I was in class or driving for most of it.
 
Not that different. Less usage, more standby.

Anyways, try to reset settings, network and privacy and let us know.

I will this weekend probably. Too much of a hassle during the week.

The part you don't see though is that the first screenshot I posted was just a few hours. The second one is after a full day. I know the first one said 7 hours of standby, but I only had it off the charger for 4 hours when I took that. The numbers seem all messed up right now. Hopefully a reset will fix it.

It is not a pain to do. You can quickly do it from settings > general > restore. It will not delete your data. Just your settings.
 
Coconut battery! You can definitely tell it's old, and it's been used.

67% is not good. Better to change it. Anyways, a full restore is not that useful (the problem may appear again after a few days). Try just with the settings restore, before doing anything else.

I reset settings. But I reapplied the ones I had changed before that I have good reason to believe affect battery life (Bluetooth off, background app refresh off, location services set to while using or off, etc).

Before doing that I thought I was in the clear after deleting and reinstalling Facebook. It was fine over the weekend when I was sleeping in, but it dropped to 20% halfway through the day at school today. I even cancelled my Genius Bar appointment when it looked fine mid-afternoon around 2:00. So I guess it's a tad better than it was last week, but it's still not what it was a few weeks ago.

Background app refresh has an impact if you enable Facebook. If it's off, the drain is not important. I'd enable it, it is useful. Anyways, as Coconut highlighted in the test, you've to change your battery.

Well, it seems that Facebook might be able to run in the background unrelated to background refresh, so that might play some role.

I really have no need for my Facebook feed to constantly be updating in the background, so I leave it off. It's only turned on for the Fitbit app so it can keep track of my sleep overnight.

I should also mention that I have a habit of closing apps out of the switcher after I use them, so theoretically Facebook shouldn't be doing anything unless I'm using it. That doesn't mean it isn't though, of course.

There are several threads of people complaining about battery life with 8.4.1 on different devices including the iPhone 6. It's seems possible that there are a handful of us experiencing the same thing. Hopefully if that's the case, iOS 9 will fix it.

I know my battery is old and showing wear anyway, so it may be time to use that as leverage for getting a new phone for Christmas ;) I'm taking a wait and see approach at this point. Restoring settings doesn't seem to have changed anything.

At every update, there are people complaining about battery life.

Sure. And I'm inclined to believe this one when there seems to be no other likely explanation.

You posted a couple threads just like this a few months ago, and I gave you advice then when I was able to go a full school/work day without charging. Surely you can understand my frustration that that's not working for me anymore.

I understand that, but if you already tried to restore your iPhone and it didn't work it seems to be an hardware problem. Anyways my iPhone is doing better now. But it's an iPhone 5 related problem. Apple wants us to switch.
 
SUCCESS! I finally got a Genius Bar appointment this afternoon, and the Genius determined that my iPhone 5's battery degradation was not the norm and offered a free battery replacement. My suspicions were correct. Thank you all for any advice you provided.
 
My iphone 5 has exhibited many of the same symptoms as yours. I took it into the Apple store and was told no dice. Not eligible for a replacement, despite often dying at 15%, 20% or 30% without any warning. Its very aggravating. I can live with bad battery life. I can't live with wildly unpredictable battery life!

But an even bigger problem is the data signal strength. Has anyone else noticed a degradation of network access on their 5s? I used to have rock solid connection everywhere in town, but it's gotten more and more difficult. More "can't connect to the networks", more 3g or 1x service in areas that used to be strong LTE. Is this my imaginiation or has anyone else had a problem with this? Are antennas improved in newer units (6 or 6s?)

I guess I got lucky. My serial number doesn't qualify for the battery replacement program, but my phone does fall within the manufacturing range for the program.

I'm not losing LTE, but it does seem to be a bit weaker than it was. 1 or 2 bars these days when I used to get 3 or 4. My carrier is Verizon. Who is yours?

I've actually seen "no service" in spots with solid at&t signal (and my husband's 6 has 4-5 dots) since I upgraded to 9.0 on my iPhone 5. So yeah, something is strange. Now I always had problems with Verizon in my area gong to 1X, but since you said it's a new occurrence we'll assume it isn't the network. That's only 2 anecdotal experiences on 2 different networks though.
