Is there a way to prevent your iPhone from charging while connected to a computer? I have a laptop and am annoyed that my laptop battery is drained to charge up my iPhone every time I plug in my iPhone for updates. Interestingly, my iPad does NOT automatically charge while connected to a computer, so there must be a setting somewhere. Thoughts?
Thanks,

Thank you all for your responses. I don't like plugging in my laptop when it's above 25%, and the iPhone iOS updates take so long to download and install I've had problems with my laptop running out of juice before I can get back to my computer and plug it in. (I don't just sit there for hours and monitor it. Who has time for that?)
Thanks again for your responses.

That's not how those batteries work. The charging system won't 'overcharge' the batteries. You can leave it plugged in permanently, and it won't harm the battery. Repeatedly depleting the battery to zero then recharging it its far more wear & tear on the system. It's like letting your car run at 'idle' at a stoplight or in heavy traffic where you're stopped. Starting up your engine puts far more stress on it than letting it idle for a few minutes.

no, so why don't you just disconnect it when you're done or keep your laptop plugged in?
The iPad doesn't charge because your ocmputer isn't supplying enough power to it.
Your iPad doesn't charge because it requires a minimum of 1 Amp to charge, and most laptops can only supply 1/2 Amp. The iPhone, however, only requires 1/2 Amp to charge. That's why the phone charges, but the iPad does not. However, there's no way to prevent the iPhone from charging unless it is charged to 100% before you connect it.
There is no setting to change this behaviour. The iPad doesn't charge because the USB ports on the computer can not provide sufficient current. Could you not connect the laptop to AC power when performing updates?

While you may have had to replace batteries, that was probably not the reason.

You couldn't be more wrong. No computer manufacturer would design a product that would damage itself simply by keeping it plugged in.

No..you replaced them because you kept letting the batteries die...shortening their life by using up all their "cycles" .

Why?

Why? There's no logic behind that.
