Calibrate Battery

Doing that now, hopefully it helps. I've noticed since charging back up, it doesn't drain as fast.
You should absolutely do this.
When I buy an iPhone, I do it at least 2-3 times in a row. Then I do it twice a month from there. I've found that it does improve battery life.
Did you let it run out all the way and keep it off for a few hours first, or just run it down and recharge?
It's really your choice if you want to run-down your battery or not. Lithium-ion doesn't really need to do that because it has a higher power density. If you keep it charging overnight that's no big deal either because once it reaches 100% it sort of goes into "idle" mode.
Why?
Another Apple post says you should run down your battery at least once a month from 100% to dead.

So in the end, it's up to you.

maybe the battery meters aren't always as accurate, or maybe there were other things such as having better signal or less things running
I suspect the calibration has more to do with getting the battery meter right then anything to do with the battery life.
Thanks everyone. So we have some say do it, some say doesn't matter, and some don't know what we are talking about lol. I'm pretty sure the purpose is to display battery percentage more accurately. On my old i4 I never got the advertised 10 hours of use. I understand that it varies by use, but kinda felt like it wasn't what it should be...
Doing it now w. my 4S. It's down to 2% so charging it overnight after running it straight outta the box. Not sure if it helps but I've done it for my 2 other iPhones and never had to replace a battery so...

Ran it down, and recharging now. I'm at 99%. I can say after running it down and charging back up, it seems better.
