    Default extending battery life

    I have tried to research this topic but I was hoping to find a definitive answer on what the best practice is for charging the iPhone and hopefully extend its life to its maximum potential? Is it better to constantly charge the battery even if it's only down 90% or 80%? Or do you normally wait till its around 50% or 40% or even 5%?

    i dont think it matters, but keeping it plugged in saves your battery.

    "keeping it plugged in saves your battery....". I guess this should be the case. As all of us had used so many brands of mobile phones over the years, keeping it plugged whenever you need it did no harm at least, as far as the experience goes!

    Keeping any device with a Lithium-Ion battery plugged in is definitely not a good thing to do. Do a search on the net for advice on looking after your laptop battery, and you'll find that keeping it plugged in and only rarely using the battery results in significant loss of charge capacity.

    Of course, I wouldn't expect that people would keep the iPhone plugged in for days at a time (which is what often happens with laptops), but you never know.

    Another good tip is to never let the battery run completely flat. This is very bad for Lithium-Ion cells. When the phone warns you that it's down to 20%, I'd plug it in for a charge as soon as possible. At other times, it doesn't matter when you plug it in. If it's down to 60%, then it's fine to plug it in and charge it up. When people talk about the number of charge cycles that a battery is good for, they mean complete discharge, followed by complete recharge. In the case of Lithium Ion, this normally means discharge to 10%, then recharge. So, if your phone is down to 50% and you recharge, that's only half a charge cycle.

    Other than that, temperature is important. The capacity of Lithium-Ion cells is dramatically reduced in low temperatures, and the discharge rate increases. At 0 degrees C, you can expect a 20% reduction in lifespan, compared to 20 degrees C. You should also avoid charging the battery if it's cold. So, if you happened to leave your phone in the car overnight, and it went below freezing, don't charge it until it's reached room temperature.

    thats my personal pet peve right there with L-ion batteries is they get memory over time if you dont discharge them correctly

    plus other things could leave to poor battery life, that run and you not kno it:
    Wifi - turn it off when you not using it
    EDGE - well u gotta leave this one on pretty much
    SSH - it even says it when you install "May drain battery"
    Phone - Always on (unless you want to go MIA)

    User standalone stuff:
    Music - takes a lil juice to beat your eardrums
    Videos - Showing off takes power
    Mail - change autocheck to a very later setting, of off (how come yahoo aint got autocheck?)

    and thats all i got off hand.... anyone else knows wht sucks up bat life

    You may want to know what the seller says about li-ion batteries:
    http://www.apple.com/batteries/

    And, of course, what this good seller has to say about best practices using your iPhone battery:
    http://www.apple.com/batteries/iphone.html

    And after that, you might want to take a deeper look into Lithium-ion batteries, have a piece of this site:
    http://en.wikipedia.org/wiki/Lithium_ion_battery


    If you want an advice from an unknown fellow, extremes are really bad for li-ion batteries, i.e. DON'T LEAVE YOUR BATTERY RUN OUT OF CHARGE and DON'T LET YOUR DEVICE PLUGGED IN CHARGING TOO MUCH TIME. The first advice it's because li-ion batteries need to be constantly "in move" for better performance. The second it's because of heat, which leads to a poor battery yield.

    Just charge often and try not to go under 20% and you should be ok for 2 years. This batteries lose 20%-25% of capacity every 2 years, more or less.

    If you want to see a battery stress result on an almost new iPhone go here:
