How to stop USB charging

does anyone have an idea on how to stop the usb charging process? cause everytime i wanted to connect with itunes, it also charged my iphone battery, i don't want to lose the charging cycle everytime i sync with itunes.

battery has a limited amount of charging cycle, about 300-500 times charge, after that battery will become broken, so i think i wanted to use the charge cycle efficiently considering there is no way i can change the battery when it is broken

thanks for replying

While your charging figures are true, that is the number for full charge/discharge cycles. Plugging your phone in for 15 minutes would not count as a charge cycle. Check this link out:

Oh, and so long as it is plugged into a powered USB port it will charge. No way to stop it.

the battery is not going to break after 300-500 charges. it will just "drizzle down" so to speak. just like everything else that you use. do you have an ipod? it's the same thing. don't worry about it too much!

ok i get all confused here.... what is a one charge cycle?

what i get from the graphic is if you charge iphone even only for 30 minutes not until 100% it will still count as a one charge cycle

i get horibble standby time over here only last about 1 day, so i really hate it if i have to dock it everyday to charge and that is going to lose my standby time even more, eventually when it gets to a year i had to throw this gadget to garbage because the battery won't even gonna last for 30 minutes of phone call (2 times docking for charging--> 2x365 days--> 730 charge cycles right?)

or i'm on the wrong point of view over here? can someone explain it to me?
because i used to charge my cellphone everyday even if the battery still 50% or so and i get really bad standby time after one year using it, it's a nokia N70, someone advice me that in order to maintain the battery life i had to used it until at least 10% than charge it all the way to 100% full capacity

and *** is apple doing with iphone? they did not provide a way to open up the phone to change battery, on ipod i can really understand cause i don't used it everyday so i think the battery would stay in good performance for a long period of time, but we use iphone everyday, listening to music, receive or make calls, even web browsing using wifi, i think in about 1 year battery would run out of standby time

If you charge from 50% up to 100% twice that would degrade the battery as much as a single 0% to 100% cycle. The battery will eventually fail, but it won't based on a specific count.

You should probably go down to 0% and then charge once a month, but it's good for the battery to keep it continually topped off.

This is based on their laptop battery recommendations.

A charge cycle is a complete 100% drain and recharge. If you only use 10 percent of your battery each day and charge it every day it will take 10 days to use one recharge cycle.

I'm surprised we are STILL getting iPhone charging questions at this point, but there it is.

Ok...here it is:

Day 1, use 20% of Battery...Recharge
Day 2, use 40% of Battery...Recharge
Day 3, Use 10% of Battery...Recharge
Day 4, Use 30% of Battery...Recharge=1 Charge Cycle

The Battery after 400 or so Cycles will then deminish or loose about 20% of its charge holding capacity...it WILL NOT just up and die.

You then have the opportunity to have Apple replace the battery at your convience.

USE your phone, charge it when you want and stop worrying about something that will never affect you. You will end up replacing with a new iPhone or something else long before your battery ever gets close to being just plain DEAD.

Hope that clarifies everything

Good Luck and Enjoy!!!

I have looked at all of the replies here and they tell you any details. I do believe that when you connect your iPhone, you can stop charging by pressing the EJECT BUTTON next to your iPhones name. This should stop the proccess. If this does not work, I do not know what to tell you.

Exactly. After those charge cycles it will simply loose some capacity (maybe 20%)
