As you all know, the iPhone’s battery cannot be replaced by us…it has to be sent to Apple to be replaced (yup, just like the iPods). It’ll cost you $86 and will require you to give up your iPhone for 3 days..oh, and all of your data will be erased (a simple sync with iTunes will restore your data).
According to the Apple site:
A properly maintained iPhone battery is designed to retain up to 80% of its original capacity after 400 full charge and discharge cycles. You may choose to replace your battery when it no longer holds sufficient charge to meet your needs.
Hmm, I don’t know about you but I don’t do a full charge and discharge cycle every day, week, or month so I wonder how long the battery will last when I mostly do full charges from a 50% discharge. At the end of the day, I expect the lithium ion battery to last as long as your typical Li-on battery. So, hopefully, I won’t have to spend $86 to replace my battery within a year.
