Was wondering do you charge every day like the older iPhones? Or do you drain the battery all the way then charge it?
Every night at bed time just like my past iPhones. Although lots of times it still has ~50% (sometimes more) battery left. With my 3G it was either dead and had been charged a little in the day, almost dead, or around ~25% left.
Loving this battery so far, no more worrying and I haven't even had to use my car charger or extra cable at work yet during the day.
I have owned all 4 iphone models and charge them daily. Every now and then I would purposely drain it all the way just to cycle it. Like a previous poster said, sometimes I charge it at 39%, 55% and even 75%. I do use the i4 much more than previous models, so I know that previous models would've drained quicker compared to the i4. I'm estimating 2-3 hours at most.
It's not a big deal to charge it daily as long as you completely drain it at least once every month or so.
I do it every night, but I have to say that I generally always have 40 to 50% of the battery life left. Sometimes on the weekends if I know I am hanging close to the house I may skip charging it. I have gone 2 days on a slow weekend.
I charge it every night only because it won't last me two full days. I work nights and my music is playing for the full eight hours. I'm usually at fifty percent by the end of my shift but it won't last me until the end if the next shift.
I am a former iPhone user. I have been trained by my old iPhones to charge every chance I get. I am only comfortable when my iPhone and iPad are at 100%. I am accustomed to taking a battery with me when I leave home.
That said, I find the battery life of iPhone4 to be dramatically better than earlier iPhones, satisfactory, almost comforting.
with regular modest usage (ie. not too much video, or streaming, or web browsing), I can get a full day and just charge once a day (ie. overnight)... although I'm usually at 10-20% by then...
But if I surf the web for an extended amount of time, or listen to a bunch of podcasts (seem to drain more than pandora some reason), or even just play with it and have the screen on for any appreciable amount of time (say killing time somewhere) i have to do a late day charge before I leave the office (i have an apple dock/usb cable at work just for this reason).... Of course checking twitter and FB every 15 min isn't doing any good LOL... the screen will kill any battery...
But overall, battery life is pretty decent... i've noticed a recent downgrade from JB'ing, but did a few days of fully draining/fully charging (ie. reconditioning) and seems to be almost back to normal (pre-JB)... fairly satisfied... although wish I could go 2 full work days, so ie. about 40hrs (from 7am on day 1 to 11pm on day 2) on a charge, but that's not happening... was able to with the 9700 I used to have, but there's no way I'm going back to that painful experience... lol
I do not understand how people charge at night. I tried it and the cord got all tangled in the bed clothes, not to mention my pajamas and my hair.
I honestly think when normal people charge it at night. They allow the device to be some distance away from them...maybe in another room God forbid. Mine charges in the Kitchen on the counter when Im sleep. I love my phone but there are periods of the day its not up my azz.
