iPhone 4S vs Samsung Galaxy S II
Power and Performance
Galaxy S II: The 1.2GHz dual-core processor and 1GB RAM make short work of even your most taxing, multi-tasking efforts to slow it down. But even with the 1650mAh advanced battery crammed in, you’re not likely to go longer than a day without needing a charge. The price we pay for big, bright displays.
iPhone 4S: In terms of performance, the iPhone 4S should be a major improvement on its predecessor. We've been promised double the processing power for web browsing and apps with the dual-core A5 chip. Last seen in the iPad 2, Apple also claims it'll deliver up to seven times faster graphics in gaming. This one's too close to call without a full review.
