iPhone Battery Lifespan

Inaccurate information about the lifespan of the iPhone battery has made its way to the media. According to Kent German and Donald Bell, in their article review, Apple iPhone leaves users wanting more, "...the iPhone does not have a battery that a user can replace. That means you have to send the iPhone to Apple to replace the battery after it's spent (Apple is estimating one battery will last for 400 charges -- probably about two years' worth of use)." German and Bell's report also claims that "Apple is estimating one battery will last for 400 charges -- probably about two years of use." 

In response to this, Apple marketing vice president Greg Joswiak stated that, "Most iPhone users will realize, as most iPod customers realized, that they never needed to replace their batteries." Joswiak goes onto explain that, “After 400 complete cycles, the iPhone’s battery still has up to 80 percent of its charged capacity,” Joswiak said. “And by a complete charge cycle, I mean completely draining the battery, a full chemical cycle.” If you are like me, and don't always wait until your iPhone battery is completely drained before recharging it, then the charge would not be considered a complete charge cycle, according to Joswiak's logic. If you recharge it half way, then that is considered half of a charge. 

If you do need to replace your battery, apple offers the battery-replacement program. If your battery is still covered under the one year warranty, then it will be replaced for free. Apple offers resources for teaching you how to extend the lifespan of your iPhone battery on the iPhone battery page. The benefit of doing this is that you are less likely to have to replace your battery before your next iPhone upgrade.

  2. Nice I also share with you something hope this helpful for you my friends Well, having seen that the board is still working and that the dock connector is somewhat usable, I went ahead and tested it on my computer. It was detected by itunes and wanted to erase the contents. That's a good sign, it means that the USB pins also work. After "combing" the pins some more to get it as straight as I could, I soldered the shield back in place.
