    Nope, it's fine. It won't hurt the battery, so go ahead. :)

    I would like to know this as well, for the same reason too! I have been charging my phone overnight for quite some time now, but did the couple battery drains at the beginning. My battery is pretty low at the end of a typical day anyhow.

    And what makes you think it would be detrimental?

    Heat and overcharging for the most part. However, most modern charging systems have programming built in to prevent damage from either.

    Yes, it will slowly make your battery soft and squishy over time and then your battery won't charge anymore.

    You're supposed to plug in the phone and then go grab a standard kitchen timer and set it for 1 hour. If the phone isn't charged at the end of one hour, set the time for 30 minutes and repeat until the phone is fully charged. This is all in the iPhone manual.

    Not to make the op feel bad but cmon now people. Are we reallo asking whether or not at this point in time it is possible to harm a devce made specifically for repeated charging?

    It will harm your battery life to subject your phone to excessive heat and cold though. When you charge just don't Cher the phone up with anything. Overheating batteries can lead to rupture.

    Your iPhone battery is nowhere near as big as a laptop battery though and does not provide the same voltage, so go ahead and charge it overnight with confidence.

    You're definitely over-thinking. Let me ask you this? Is it ok to keep your laptop plugged into the power cord?

    The iPhone is smart and stops taking power from the power supply once the battery is fully topped off. That's why when you charge it overnight and touch it in the morning, it's not hot: it's because it finished charging hours ago.

    Some devices DON'T stop charging when they're full, and it's those you should be worried about.

    Yeah? On the iPhone_user_guide.pdf pg 33-34 cover charging the battery.
    Only a vague sentence refers to battery life :"Rechargeable batteries have a limited number of charge cycles and may eventually need to be replaced."

    Given the power demands on this phone it makes sense to plug it in whenever you can, unless it's going to seriously shorten the battery life.

    So far the plug it and leave it gang hold the most compeling argument

    actually 100% yes.

    Hightech batteries have chips in them so they will not overcharge. Laptop batteries start on fire because of leakage due to poor manufacturing ECt

    No, it's actually not the way how the Li-ion batteries are designed to charge frequently. The best way to keep the batteries in good condition is to keep the electrons inside flowing. So, always keeping the phone on the dock is not a good idea.

    Never saw this thread back in the day but isn't this what 99% of the population does with their mobile phones? :confused:
