So I'm on my fourth iPhone 4S 32GB. The first two had the exceptionally loud vibrate motor, so I returned them. The third one had so many issues that upon returning to the Apple Store, the Genius indicated it was the first iPhone they'd ever had that their diagnostic computers couldn't connect to. All four phones have had the loud vibrate motor, and all have had terrible battery life. But the current one is the worst. It drains 10-15% on standby and if I have it actually in my hand using it for about 60-90 minutes a day, I have to charge it twice. It also dies well short of 0% (as high as 25% before). To add to that fact, I've compared it alongside more than one iPhone 4 and it gets crushed in every single "speed test" that I can find. Mine on a good day will average about 500 kb/s. And this is with everything (location services, iCloud, iTunes Sync, etc) turned off, while the iPhone 4 has most of it turned on. In every way shape and form it is inferior to the 4 and in some cases even my 3GS. What would you do? Is this just the nature of the phone we're all stuck with, or should I go back and demand yet another phone?
