Yeah let it drain and charge it up.. be prepared it will take a long time to charge :/
My battery life is already better just after one cycle
Is it safe? If it's quicker and safe why wouldn't apple sell it as an iphone charger?Using an iPad charger is a lot quicker.

I suggest you guys read from the experts instead of guessing. If you think draining a battery down to zero does not affect the battery your are sorely wrong.

Simple Guidelines for Charging Lithium-based Batteries
A portable device should be turned off while charging. This allows the battery to reach the threshold voltage unhindered and reflects the correct saturation current responsible to terminate the charge. A parasitic load confuses the charger.
Charge at a moderate temperature. Do not charge below freezing.
Lithium-ion does not need to be fully charged; a partial charge is better.
Chargers use different methods for “ready” indication. The light signal may not always indicate a full charge.
Discontinue using charger and/or battery if the battery gets excessively warm.
Before prolonged storage, apply some charge to bring the pack to about half charge.
Over-discharged batteries can be “boosted” to life again. Discard pack if the voltage does not rise to a normal level within a minute while on boost.
That link and article applies for a Lithium battery. The batteries in the Macbook Pros and iPhone/iPad are Lithium Polymer Ion Batteries. How you charge them is irrelevant. Besides using a ton of cycles the only thing that can really degrade the battery is turning it off at 100% or 0% and storing it for weeks at a time. This is why new products always come at a 80%, this ensures the proper capacity for the battery while it is not being used.

Trying to run my new iPhone 6 Plus battery down to 1% so I can charge it all the way up for the first time. 12 hours in under heavy use, and I'm still at 16%. That's impressive, especially given the gazillions of notifications I get.
Disappointed after reading all those "lasted 2 days" reviews. I'm getting about 7 hours use + 15 hours standby which is comprised of WiFi 5 GHz & LTE Web browsing, about an hour of phone calls on Bluetooth (WiFi & BT toggled off when not in use), screen on auto brightness about 50-100% depending, Pinterest browsing, messages & email. I've checked Location Services, etc. to make sure nothing is jammed on and all looks normal.
This is better than my 5S to be sure but just not quite the mind-blowing performance I was expecting. Here's a screenshot at 5% battery on a typical day...
