Another big plus for the iPhone 4 is, despite being the thinnest smartphone ever created, the battery life hasn't suffered. Far from it, as Steve Jobs actually reckons it can last 40% longer despite the smaller chassis size.
And you know what - he may actually be (sort of) telling the truth here. Seasoned iPhone professional users will know that to use a couple of applications, watching a 30 mins of video, downloading new apps, run music through Bluetooth and also keep opening and closing it to perform other tasks is a real battery sucker, and usually means your iPhone won't see out the day.
Well, doing just that sat at our desk, we actually found that in a seven hour period, the battery only dropped 50%. It might sound a little drastic, but over the course of the day, when you're using the phone a lot less, this works out to be a much nicer figure to work with.
We actually found we didn't need to carry around a charger all the time when we were using an iPhone 4 - and even if you forget to plug it in at night, it won't be until sometime the following day it completely shuts down, which you have to applaud when you see how thin the chassis is here.
Of course, this isn't the all-encompassing fix we've all been waiting for in smartphones, as a simple hour's commute with push email, music and the camera all in use will drop things by about 10%, but that's not standard use.
This is helped by an all-new processor, the Apple A4 effort that's really good at not sucking down too much power even when performing those pesky multi-tasking tasks. We're impressed with Apple, as its iPhone range has gone from one of the worst on battery life to at least one of the better ones.
The iPhone is, as you'd expect, jam-packed with functionality. You've got an upgraded Wi-Fi chipset in there to now cater for the faster 802.11n hubs, and of course we're treated to GPS, Bluetooth 2.1 and A2DP as well as the normal HSDPA and 3.5mm headphone slot.
The Bluetooth is impressive as ever too - simply search for and pair with a Bluetooth headset, and whenever the iPhone 4 finds that unit broadcasting a signal in the future it will connect automatically - which makes it much easier to use.
The GPS, as we mentioned earlier is lightning fast, but it's a real shame about the reception issues with the data - we really thing the signal dropping is going to annoy a lot of people when they've shelled out so much money for a new phone.
