Not a significant amount, but saved me a few percents over the day.

There are just so many routers in my apartment and on campus that sometimes the phone would be on one and the computer on another so I'd try and send an SMS from my Mac and it wouldn't work.

Ah I see. In that case Text Message Forwarding isn't really that worth disabling for me then. Especially since I don't use it a ton I don't think it'll make a big impact, and it works flawlessly for me since I have just one router in my house and I don't get any of those nasty iOS 8 WiFi drops. It doesn't really work at school though since it uses a weird log in system for the WiFi and you get booted off after you haven't used it in a long time. Doesn't play well with iCloud related things at all.

Anyway, it's kind of annoying that as soon as I can start really trying to measure my battery drainage again since restoring, my friend shows me the game "Evil Apples" which is pretty much "Cards Against Humanity" and it drains my battery by an absolutely astronomical amount for some reason. 20-30% in an hour at 45% brightness is what occurred the first time I played.
 
just got my iphone 5 battery replaced via apple's replacement program and its night a day to what it was before. It works great and lasts like a normal battery now.

How long have had your iPhone 5? Just curious if you've had it over 2 years and they replaced your battery anyway.

I downloaded ibackupbot and here are my numbers:

CycleCount: 628
DesignCapacity: 1430
FullChargeCapacity: 1400

I typically can still get a full day with a charge as long as I don't text too much. Would a new battery make a huge difference?

BTW, I bought this phone from a buddy of mine a few months ago. It was bought new in September of 2012 and the serial number does match those in the battery replacement program. Do you think they would still honor that?
 
Many things can cause a battery to discharge at a variety of rates. Bad iOS, bad battery, bad other hardware, etc.

But one needs to understand the nature of wireless communication even in the climate of not consciously/actively using the device. You could charge it up to 100% and not actively use it and just by being mobile (drive around town, between towns, etc., the battery can and will discharge in a non-linear, non0predictive manner.

Why? Well, there are a variety of expected, by design and engineering, reasons. :) There are power optimizations taking place constantly between your handset and MANY cell transceivers. If you think triangulation means you are communicating with only three towers at any given time then thing again.

Additionally your handset is constantly being told to lower its transmitting signal strength and then back up again by multiple radios on multiple towers. This is partly to minimize power on the carrier's network, but also to predict your movement and to prepare another tower in case that prediction is correct.

Then there is increased power on your handset's transmitter in increasing shielded environments, in the environment of others transmitting near you, near your optimized tower, etc. All of this dynamic power-related behavior is completely transparent to the end user--unless you are in RF design, of course. And yes, I took a couple of classes in RF design for one very large wireless carrier in the US. :)

Now, aside from all that mumbo-jumbo I just said please keep the following in mind ...

Before I bought my iPhone I had a My Touch 3G made by HTC and branded by T-Mobile. I had it for eighteen months before the charge on the battery changed dramatically over night. It use to have a standby for days, but then changed to 4 hours.

I could charge the battery and remove it and it would hold the charge. I could put the charged battery back into the phone but leave it powered off and it would continue to hold the charge. But as soon as I turned the phone on it would discharge in less than four hours.

It wasn't the battery, not how I let it sit on the desk doing nothing. It was the hardware in the phone. Something failed and that failure caused the battery, which was good, to discharge rapidly. My response was to "F-HTC!" and never bought one of their products again.

Not advocating Apple, its hardware or software, but just keep in mind that the nature of battery energy going somewhere can have a large arena in the final root cause.
 
Signal strength seems to make a noticeable difference for me too. My battery drops into the 90%s faster when I'm in my weekly classes as opposed to the building I go to for church services (which has a stronger signal).
 
Confirmed signal strength has a huge impact for me. Didn't touch my phone at all for an hour this morning while I was in class (almost zero service) and lost almost 5%.

Yesterday had good coverage and stayed at 100% for almost an hour of basic usage.

It was over 2 years old, yes

the replacement program goes until Mar 1 2015, I believe. So if your iPhone 5 qualifies for the program, try to make an appointment soon!

Its only the sleep/wake button program that has the 2 year limit, which in my opinion was ridiculous - these were genuine problems with the phone and some people have no way of knowing there was a replacement plan. I had to get my lock button independently fixed, luckily from a reputable local iPhone guy who charged less than apple and did a fantastic job.
 
Might qualify for this replacement program.

Edit: someone was faster than me.

Fyi Apple replaced my girlfriends iPhone 5 with battery issues without warranty. And it didn't qualify the program.
