The Apple iPhone 4S might be a small upgrade if you were using the iPhone 4, but it is a huge upgrade if you are upgrading from the iPhone 3GS, as I was. Not only was the screen much sharper (albeit still the same size!), the iPhone 4S was much faster. Unfortunately, I also immediately noticed a big problem with the iPhone 4S - its terrible battery life. Recently, my brother pointed me to a very nice app called System Monitor with Battery Max. It`s a 99 cent app that allows you to monitor the hardware and software of your iDevice. What`s really nifty about it was it was able to give me a live read of the iPhone 4S` CPU load. What we found shocked us - the Apple iPhone 4S had a constantly high CPU load even when it idles! DO NOT BUY THE APP. Please check out this critical update : - Added results for the Apple iPod touch 4G and Apple iPod touch 3G. - Added warnings about this app. - Added a new Mea Culpa section."
