    Apple has posted some information and tips about optimizing the battery life on your iPhone.
    Apple indicates that their engineers are finding new ways to optimize your battery, so make sure you have the latest software updates. Other common sense tips include

    - Use Phone regularly. Go through at least one "charge cycle" per month.
    - Lock/Sleep your phone when not in use
    - Turn off Wifi to save power
    - Turn off Bluetooth to save power
    - Turning on Auto-Brightness
    - Turn off the Equalizer (iPod setting) if you don't use it

    Software Updates? What software updates?
  6. macrumors demi-god


    it's a general statement that's supposed to apply during the life of the product, that you keep up to date with the software. there might not be updates now, but there will be.

    I seem to be getting excellent battery life...up to 2 days standby with 7-8 hours usage. I do about one full cycle every week, and little cradle top offs the rest of the time.
  8. macrumors 65816

    Exactly! Bring em on already.
  9. macrumors 6502


    One of the suggestions was to turn off wifi. If anyone is like me its a bit of a pain to keep turning it on and off. Shouldnt apple make it where it turns off when it is asleep and turns on when you open safari? Is that even possible?

    A wish for AutoWiFi

    though i can see way folks would want it on full time to get fast email downloads and such, i think this is a start of a great third option

    something like
    •Auto (when internet apps are accessed **see note)

    (**with some sort of timed delay for shutting it down so that when your task has you popping back and forth between many apps it does not have to yoyo of and on)
    also remember that you never close apps on the iphone you simply leave them for something else or sleep mode. so it would have to be based on wither they are in use mode whatever that is called

    what would that be called, it is not off or on, not really the front window but maybe, anyone have a better way to describe how iphone UI handles apps when switching and stuffs

    Umm okay how the heck can we go thru olny 1 charge cycle...per month.. if the battery dies after let's say 2 days...? That's Impossible... apple is crazy there is no way we can go there 1 Charge cycle a month!! i never understood that!! :confused:
  12. macrumors 6502

    From reading this it makes you think that you should completely use up the battery and re-charge at least once per month. But if you look at the way Apple defines "charge cycles" that isn't the case:

    "A charge cycle means using all of the battery’s power, but that doesn’t necessarily mean a single charge. For instance, you could listen to your iPod for a few hours one day, using half its power, and then recharge it fully. If you did the same thing the next day, it would count as one charge cycle, not two, so you may take several days to complete a cycle."

    This means that you don't have to let your battery drain all the way. You can plug it in at night, every night, and keep your charge topped off while at the same time going through charge cycles like the guideline says.

    True.. BUT it's still IMPOSSIBLE to go thru 1 Charge Cycle a month!! maybe couple days but not A MONTH!
  14. macrumors 6502

    Use Phone regularly. Go through at least one "charge cycle" per month.
  15. macrumors 6502

    So The best way is charge it everynite...?
  16. macrumors 6502

    I'm pretty sure there is no best way. Just that you should use it regularly. This means don't let it sit unused for a month. Regular usage will make it cycle its charge a few times by default without you having to modify how you use it.

    If Apple is listening...

    If those common sense "pointers" are so damned important, how about making them easy access buttons in the menu or physical toggles on the unit itself (i.e., switches for WiFi and Bluetooth on and off)?

    Be PROACTIVE!!!! Don't make everything the user's fault!

    They are saying to "at least" let it run through a full drain and recharge once a month. That means DO NOT PLUG IT IN EVERY NIGHT!!! It also means to let it drain as much and as often as possible before charging. If the day's over and your at 50%, don't pug it in. Bring the charger with you should it die the next day, but let it go if you can. You should do this with every rechargeable device.

    I think you might be misunderstanding what they are saying. I thought exactly the same thing as you thought until I looked up the definition of "charge cycle" which I posted above. According to Apple, you can still go through a charge cycle without running your battery down. If you use up 50% of your battery and charge it up, then run down another 50% of your battery and charge it up, that equals one charge cycle. It doesn't all have to happen at the same time.

    I like this because I don't want to be running around with 10% battery and then have it go out on me. I prefer to charge every night and keep my battery topped off. Turns out that either way you do it (run it down or charge every night) it effects the battery the same.

    I could be wrong, but that's how their definition of charge cycle reads to me.

    EDIT: I think the important thing (as they say) is to keep the electrons moving, not necessarily HOW you keep them moving.

    Ooooooooh ok so i guess i'll charge it everynite...ur right u dnt want it to wait till it drains and and u might need th fone and only 10% left and u can't use it. Alright... hope this is correct tho..
