    Hi All...

    I wanted to know how much time does it take usually for the battery of SG2 to charge completely from 1 or 2 % to 100% of the battery charge??

    I am not sure if mine has some problem..I tried charging my fone n it took me 2hrs 30 min for getting 100% from 2% of charge...is it normal or do you have other experience??

    Any answers and suggestions would be helpful :)

    Thanks,
    DJay

    That sounds about right mine takes about that amount of time to charge as well. Unless someone here reply's otherwise which would mean me and you may have a battery issue. By the way charging your phone and maintaining good battery life should avoid allowing it to drain to 1% or 2%.

    Over-discharging Lithium-ion

    Li-ion should never be discharged too low, and there are several safeguards to prevent this from happening. The equipment cuts off when the battery discharges to about 3.0V/cell, stopping the current flow. If the discharge continues to about 2.70V/cell or lower, the battery

    Mine is pretty much the same. It does take a while but I'd rather it charges slowly as this improves cell life compared to the fast charged cells.

    And as explained above you shouldn't wait until the cells are completely discharged.... Just charge your phone when it's low or top up before you go out.

    assuming you're using the factory ac charger that comes with it then yes that's how long mine fully charges as well.

    may take a bit longer if you are charging from a lap top or net book
    They don't always have enough power for a fast charge

    I always charge mine using the USB cable provided, is that okay?
    I never used the actual charger yet.
    And I'm going away for 4 month and wont be taking the GS2 with me, what's the best way to perserve the battery? just charge it 50% and remove it from the phone?

    Thanks!

    Around 40% is recommended for extended periods of storage, same for laptop batteries. 50% shouldn't cause problems though.

    Allright thanks for your reply.
    and I guess it should be fine charging my phone with the usb cale instead of the wall charger?

    Yes, but remember that it will charge longer by usb cable than normal charger.

    Maybe it's healthier that way for the battery to take it's sweet time lol.
    But I'll keep that in mind thx!

    So is there any way of showing the battery status as a percentage on the screen, instead of just a partially filled green battery symbol?

    There are a lot of apps on the Android Market that will show the % of your battery. This is just a simple app I have been using until I start getting more sophisticated in regards to downloading ROM's.

    Thanks, does it show the battery percentage on the green battery symbol at the top of each start/home screen, or just when the app is launched?

    i use this = BATTERY NOTIFIER it sits up in the top left all the time.
    i also use this = ANYCUT where you can make a shortcut on your homescreen to access part of your settings/menu's quicker.

    Mine took 3hrs 20 Min.
    It was the third charge from 1% and I use the stock travel charger ETA0U10JBS
    rated output 5V - 0.7A
    Is this normal.
    My main concern on my SGS 2 is the battery life :S
