Battery Life
If you’re a BlackBerry user, battery life is one of the big differences when it comes to using other smartphones. My Curve has been known to go for three days without a charge and I have never had the battery die on me during regular use. I’d already heard the complaints about the iPhone 3G and 3GS batteries so when I got the iPhone 4 I was prepared for regular charging. Much to my surprise, I was able to get two days out of the iPhone before needing to charge, and that was with fairly liberal use of Wi-Fi, 3G and calling. No massive hour-long conversations or anything, but neither did I hold back. The Galaxy S on the other hand was never able to go more than 24 hours on a full charge, and even then, I wasn’t able to use it as hard as the iPhone. A few people in the office were quick to blame things like the Samsung’s larger AMOLED screen, but I don’t think the difference is a result of power-hungry components. I suspect the reality is that Apple put a much higher capacity battery in the iPhone 4 than in previous models. Apple has made enormous strides in battery life since the first iPod models hit store shelves and I think they have finally achieved a balance between weight, cost and longevity. Not being able to replace the battery on the iPhone is no longer a reason to avoid it, if ever it was.
