    I believe he means when the phone is totally off not just sleeping. To which I would think no, it would turn on by itself. But I'm not 100% sure

    @ home.
    Yes. It turns on and starts charging. If you don't want to receive calls at night, just turn on Airplane Mode.

    A hypothetical situation: You purchase a new iPhone and use for just 2 days! The battery drains out completely and you reach home after about 7 hours of your iPhones battery drying out! You plug your iPhone in! Guess what happens?

    Of course you can...

    YES~ If you iPhone is ON you can plug it in and it will begin charging. You then can Hold the Sleep/wake button and slide to power off. It will shut down completely. In the morning you can come back and turn it back on to find a completely charged iPhone. I say this from experience.

    If the iPhone is already off, when it is plugged in it will power one, but after it turns back on you may turn the phone back off.

    It turns on when it is off just when you plug it in because if you are plugging it into the computer it must communicate with iTunes.

    As Auzburner you can power down the iPhone while it's charging.

    But the downside is, unlike pretty much all the other phones out there, there will be no indication whatsoever that it is charging. But it is.

    yeah you can. you just have to cut it off after it cuts back on. i've actually heard it charges faster when it is off. i've never actually timed mine (haha) but it is what i've heard from the experts.

    Hello ,
    I recently bought an iphone 3gs and i don't know when is better to charge it.
    Since now I am charging it when it tells me that there 20% of the battery left.
    Can I charge it whenever I want , even if the battery is almost full , or I will damage the battery???
    When I am charging it does it have any matter if the iphone is open , or not???

    my battery knowledge

    I charge my phone every night. By the time I charge it the battery is down to about 20-40%. The battery should indeed get about 300 full charges. Because it is a lithium battery, this should last you about two years. (if the battery goes to 50% one day and 50% again the next day, that is ONE full charge.) If you don't need to use your phone while it's charging, go ahead and turn it off. It shouldn't make a difference in overall battery life. ALSO, feel free to use your phone while it charges.

    The best advice I can give about battery life:

    -At least once a month, allow the battery to drain completely (to 1% or 2%). This will keep the status bar accurate.

    -Restart your iPhone 2 or three times a week (with the red slider). This clears the virtual memory and allows the phone to utilize the battery better.

    -Do not use the 2-finger reset method ever! This is very similar to pulling the battery from your laptop while it's running. Use this method as a last resort to get your phone working if it's not responding at all.

    -If you're having poor battery life, 99% of the time there is a software issue causing the battery to drain or not communicate with the status bar. Restore your iPhone. Try with the backup first. If you still have weird issues, restore again without the backup (start it as a new phone).

    The End.

    Thanks a lot for the advises , but you put me in thoughts if there is any problem with the software , something that I dint have in mind before read your message.

    The problem is that I don't know if there is any problem with my software....
    When I am use applications that reduce my battery really fast ex. if i play with a game application for 2-3 hours my battery is gonna be around 50%-60% (from full) maybe and lower , and wifi and 3g will be closed and the lighting normal and the sound normal...
    If I am not use application my battery life is OK , at list I think so because it last for very long.....
    Is normal for the battery to reduce so fast from the applications???
    And if there is any problem with the software how can i do the restore and how the backup???:confused:

    Just a question,. What application are you using? If its an application based on 3D its normal that the battery is getting low rlly soon..

    Thanks, WouterTheBoy. I'm sure that Batas is ecstatic and relieved that someone has finally acknowledged his/her last post after almost three years.

    I can only imagine the agony of dealing with this open question for so long...
