Review: Samsung Infuse 4G
The Infuse's monster 4.5-inch Super AMOLED Plus display is the whole point behind this phone; otherwise the Infuse isn't that much different from Samsung's other recent offerings. The Infuse's screen - surprisingly - has the standard 480 x 800 pixel count found on many Android devices with smaller screens. That means pixel density is reduced, but Samsung will tell you the sub-pixels in its Super AMOLED Plus displays make up the difference. I'll tell you that images, text, and other graphics aren't as smooth as they are on the iPhone 4's Retina display, but the Infuse's display is brighter both indoors and out. The screen does come in handy when watching video, browsing the web, and looking over your Facebook news feed.
The Infuse was reasonably good at attaching itself to AT&T's network. Whilst in northern New Jersey, it rarely dipped below three bars and never lost the signal entirely. In both NYC and San Francisco, signal performance was a bit weaker, and it lost AT&T's network at least once in each city. I didn't miss any calls while testing the Infuse, but I had trouble connecting one from NYC. Data speeds were good.
Call quality with the Infuse is better than that of the HP Veer, but not by much. Conversations took on a nasty robotic edge at times, and sometimes I felt like voices were stabbing my eardrums. There was some slight garbling, but mostly conversations sounded overly sharp. The earpiece volume was plenty loud for most environments, as were ringers and alerts. The speakerphone was also loud, but suffered the same quality problems as the earpiece. The vibrate alert was excellent.
I barely made it through an entire day with the Infuse under heavy usage strain. From a full charge, it burned through the entire battery quite consistently at the 15-hour mark (7AM to 10PM). One day, it kicked off after just 12 hours, and another it lasted until about Midnight. You're going to have to charge it every night, if not during the day as well, if you use it a lot for activities other than browsing, social networking, and listening to music.
