    Does this make a difference If I drain the battery before I update it tomorrow? I know supposedly the software is going to improve the battery life so would I be better off draining the battery or just update it w/out full drainage?

    Take a break. You are overthinking it.

    Only if you haven't "cycled" the battery in a long while by letting it drain down to shut off and then recharge to full. Doing a reset might just be all that's needed to reset the battery "voltage clock" for any firmware changes. Most people won't even do that.

    The battery has absolutely nothing to do with the firmware...... and it should be cycled every month or two irrespective of whether you're upgrading the firmware or not!

    The last time I cycled my battery...I couldn't get it to come wouldn't take a charge...just showed the battery screen with a charge symbol but never charged....very frustrating experience:(

    thanks for the info guys. I just drained the battery two nights ago and really didn't want to drain it again.

    JFC, really? This is a little too much, but I got a nice little chuckle.

    I think you should definitely drain it. There's no way the power you put into it will be compatible with the 2.1 firmware. It seems as if you'll need to charge it after 2.1 is loaded so that the firmware can convert this electricity into a more efficient form.

    Just kidding

    Steve: They're called iElectrons and they're twice as thin and have even better battery life. You might be wondering how we did it... quite frankly so am I.

    ABSOLUTELY NOT !!! :eek::eek::eek::eek:

    Scenario: you are updating to 2.1 when all of a sudden your battery runs out of juice and the phone shuts off. :eek::eek::eek::eek:

    Your friend in the other room did not drain his battery down, and his update went smoothly. :):):):)

    (once per month, you should drain your battery all the way down until it shuts off by itself, then charge it all the way up. This is proper maintenance for the battery as recommended by Apple's website. In a post a few weeks ago, I explained the chemistry of why you do this. If you really want to know, I can explain it again)

    If anything you should fully charge the iPhone before installing the update.

    When you are installing the update and the phone reboots, it is not being charged for a little while. If your battery dies during this stage you will hose your phone and need to do a full restore.

    Just a quick question... Do you think I should put 186ml of milk on my cornflakes or 188ml of milk on my cornflakes?

    Just press UPDATE like everyone else! :D

    Actually, the correct answer is "NO, IT'S A LITHIUM BATTERY!!" Draining a lithium battery is bad for it...

    Glad that didn't happen to me. Twice my phone has lost it's charge completely (from being half charged) in a matter of 30 mins to 7 hours. Both times on complete standby (screen 'locked') with no music playing. It was very odd and once allowed me to sleep in almost past one of my tests that day.

    Wow...really...? o_0 :confused:

    You're stupidity is probably why all of these manufacturers put warning labels on their products:

    I would say NO! If you insist on cycling, do it before the update or afterwards, BUT ensure you have well over 50% of charge while doing update.

    Calibration of battery can be done any time FYI, and has nothing to do with firmware update.

    And make sure you put the phone in airplane mode before you update. That way it won't get interrupted by phone calls.

    You don't have to drain the battery but make sure you take it out of its case (unless the case is red leather or blue silicone).
