Is it normal??? On the iPhone 4??
I don't think it is
Are we supposed to guess which iPhone you have?
I'll use my masters degree in mind reading.
So 5 minutes = 1% battery
Ergo, 5 x 100 (total battery %) = 500 minutes
500 / 60 = 8.33 hours. no?
Make sure Push email is off if you do not absolutely need it, as well as location services... Keep your brightness around half or so.
I'd charge up completely and then drain completely to calibrate if those things don't help. Sometimes it takes a few usage cycles for these batteries to perform their best.
if its on standby its supposed to be 300 hours...
But no normal person will ever see that.
This forum is starting to bug me now. Good thing my MBP only has 6% battery left
Ah. I assumed he meant while using the device..
If you are correct about that than you would be getting 8.33 hours of battery life on your iPhone, that's actually pretty good!!
Depends on what hes doing. If hes not using it much, thats quite terrible.
I'm actually having that same issue and I noticed that my battery percentage indicator won't disappear even after disabling it in settings.
Oh great jeebus, not again.
Please read the zillions of 3GS posts on battery issues from last year. Here's one to get you started: http://forums.macrumors.com/showthread.php?t=728224
(Jeez, battery calibration!)
Somebody hasn't turned their brightness down yet : p
Double click the home button and kill all the unnecessary apps running in the background.
I can't wait to get my 4 so I can test it's power management myself. I'm the kind of person who usually turns my brightness to the highest. Why have a Retina display when you can't enjoy it? Why stunt the features available for you? I'm gonna turn on my location services and push of Mobile Me and probably run Skype or IM in the background. Only essentials. I do hope Apple's claim of good battery life is okay. With my uses, I just hope it'll last thru my normal day before it'll dock on the charger by bedtime. I'm optimistic after reading Engadget's review of more than 2 days of normal use.
I have been running 10 apps in multitasking... Pandora playing music with the screen on Full brightness and leaving the pandora screen up at all times for about 2 hours with location services on, push at every 15 minutes, and anything else I can have on and runnig.... keep in mind I have been using this thing non stop almost since 3:00 today when it arrived and its now 1 in the morning.... that's 10 hours of use with almost 2 hours of HARD major use and I'm still at 19%
Man I couldn't ask for a better battery... I am trying to drain it dry before I go to bed so I can have a full charge tomorrow... Plus its good to do a FULL charge then drain of your battery the first few times to help with the calibration.
The battery in my opinion is AMAZING !!!
phone just shut off cos battery got drained. Got 8hrs and 12 mins usage and 12 hrs 42 mins on stanby.
I say it's pretty decent!
There are no apps running in the background! That's the whole point of Apple's strange multitasking implementation.
I suppose another way to phrase it would be the following. What do you think?
An App only consumes battery life if it is doing something for you.
Skype (when released) allows others to call you
Pandora plays music for you
Battery life seems better after I turned off locate services...
You won't get 300 hours if you light up the screen every 5 minutes to verify it went down 1% or if you leave the screen on to watch it go down 1%.
