You also need to "train" your battery. You do this by allowing the battery to completely drain before fully charging it. Do that a few times and the battery manager in iOS will "know" how to charge the phone based on your usage.
There is also a trick that works on some Android phones that you might be able to try: charge your phone until it is fully charged, unplug the charger, power off, plug the charger back in and continue to charge.
If what you say is true... then the battery charging and power-left sensing algorithms in both the iPhone and Android platform are misdesigned. Which I doubt, considering the generally proficient engineering teams behind the products... Fairly certain that this kind of wizardry in reality doesn't work, it's just a few empirical observations and rumors that have gained ground.
I have designed charging algorithms for both Lithium Cobalt Oxide (what most people refer to as 'lithium ion') and lithium iron phosphate batteries. To note when a single cell (most phones are single cell) is fully charged (95%+), given one can measure the charging voltage and current, is easy. Actually just the voltage over the cell is enough if it's accurate to within a few percent and the final part of the charging can be done slowly.
Ditto on the other side, it's fairly apparent when the capacity of a cell has fallen below 10%. Now, to know how much usable energy is left in the cell if it's not almost empty or almost full is harder. So deep cycling it, topping up, etc. may however calibrate the battery gauge. But I don't think the actions actually prolong the battery life, as in usable standby or talk hours before the phone dies.
I don't get people needing to trash one person's choice of phone over another person's choice of phone.
Yea, and I don't "get" why people can never seem to tell WHEN I'M TRYING TO BE FUNNY?!?! Why is everybody so eff'ing sensitve on this board? Is it because we just expect everyone to be a-----'s? STOP IT!

That one means "you're an idiot"...
Not you.
It's hard to distinguish sarcasm through text. I found that out the hard way a long time ago lol
It's magnified here on CD because there really are some loonies here (especially in the politics forum) that say some ridiculous things and wholeheartedly mean them.
I've been told that with the newer Li-Ion batteries (which apparently are used in all cell phones now) do not have to be 'trained', nor do they respond to it.

For Apple's sake, I would say that they engineered the phone to make the best use of the battery. But as many users report, the battery life does not live up to the specs. Seeing as how the iPhone came from the iPod Touch and the iPod Touch was specifically designed to be a gaming/video/app/music/entertainment device, you would have thought that Apple learned a few things about battery management by now. In a way they did. That is one reason why the iPhone "lacks features" found on Android competition. According to Apple, the iPhone 5 is supposed to have a total stand-by time of 225 hours, which is just over nine days. Apple also says that the iPhone 5 has 8 to 10 hours worth of browsing time depending on how you connect to the Internet (LTE, 3G, or Wi-Fi, respectively). I doubt that, though, as the reality is that the strength of the signal determines performance for anything that requires an over-the-air signal. As it turns out, Apple Headquarters gets a pretty darn good cellular/3G/LTE signal. Supposedly it is one of the best in the Country.
Android is largely based on the specific phone. Some Android phones have horrific battery life. Others are not so bad.
Apple recommended that I drain the battery before a first charge for every battery-powered Apple product I have bought since the original iPod and my ex GF bought a MacBook Pro about six months ago and was told the same thing. They said that the battery needed to be trained to gain optimal usage. I've heard this from other sources regarding products from other companies, so I can only imagine it is true as I am not one who would be in a position to know otherwise. I just assumed the same was true with the iPhone 5. This is the first time I have heard different.
The Android charging trick is well documented on pretty much any Android-dedicated forum you can find.

Yah, I'm not saying that the tricks do not work, but I am having a hard time believing it. I'll be very surprised if they do anything other than calibrating the gauge. Definite device shutdown is typically carried out at a certain voltage trip point. Maybe people generally charge their phones before they die, and don't realize that quite some time is left in the not too representative red battery indicator. Once I ran a longevity test on my Xperia X10 by playing movies. The movie continued playing for almost two hours with the battery indicator all the time stuck at 5-10%. Poorly calibrated gauge would surely have had many users charge the thing when there actually was 50% left.
Well, I have drained the iPhone 5 battery completely now twice and charged it back up to 100% twice and I am seeing no real great improvement. I am getting about 6 hours of "usage" time, or at least that's what the phone says. So if this is going to be my reality, I have a question: Do I always have to let it drain down to 1-5% before I charge it, or can I top off/charge the battery by the evening when it's at 40%?

Calm down. Sheesh.

On the contrary. You should avoid to run down lithium batteries to the far low end of the gauge as this will wear them out faster. So go ahead and charge it at 40%.
