Just wanted to get some of your thoughts/opinions as to why no lithium polymer battery in iPhone 4? It has the iPad's A4 but yet uses outdated and inferior battery chemistry? In my personal experience, the Li-ion in the previous gen iPhones always tend to lose capacity and stamina after roughly a year of life, given roughly daily charges (300+ per year). This is one of the main reasons why I'm considering the upgrade from 3GS to 4, among others, but if my 3GS battery still performed as well as it did a year ago, I would consider hanging on to it. Is this by design, and/or somehow Apple's secret conspiracy to shorten the lifespan and speed the product refresh cycle? I would think since the battery technology in the uMBP/iPad is so highly touted and desirable, Apple would like to highlight the dramatic increases in charging cycles, phone stand-by times, and stamina in the iPhone 4 as well, in addition to differentiating it more from it's competitors, rather than just marginal gains due to increasing battery capacity and decreasing logic real estate. The iPad has done well in this regard, considering it's amazing battery life, and is seen by many to be it's "killer feature". Thanks in advance.
