The ip5 is a lot better graphics-wsie compared to the gs3, I'd say it's better than the DNA as well. As for battery life I've owned both the ip5 and gs3 and the ip5 has far better battery life in my experience. I'm a pretty heavy user and the ip5 lasts me easily over a day, while the gs3 needed to be charged every night.
I am curious how you believe that the Ip5 is better graphics-wise than the GS3? The GS3 has a better screen resolution and a larger screen. And, if from what is being said above, power and download are comparable between the three devices, I would think that the GS3 has it all over Ip5?
Now, I know that there is some question about brightness for the DNA, but that, it would seem, is a separate issue entirely.
Just to clarify a few points. Yes, I am on Verizon.
Also, while I am concerned with battery life, I am not hugely concerned. I am not a heavy user. But with that being said, i don't want to tap out. My general usage pattern consists of about 30% calls, 40% emails and 30% web surfing/games/videos. And again, I would rate myself as light to moderate usage.
My research suggests that both the Iphone5 and the GS3 will have satisfactory battery life to meet my needs. As far as talk and standby, it looks like (based on numerous site comparisons) that the GS3 has significantly better battery in the realms of talk and standby. Not sure how accurate, but I am going to go with the benchmarks of Anandtech, Gizmondo and Cnet. Individual experiences may vary. At the end of the day, I would rate myself at normal usage. And am generally not away from a docking station for more than about 12 hours at a stretch. Plus I plan on having a power cord for my car, so....
About flash. I know that some web sites still use flash, so it is a concern. Although I gather that it isn't a huge concern. So that is new information to me. Thanks for that.
Regarding removable battery and SD card, these are not huge concerns on my radar. If the battery fails, I expect it to be under warantee. And I don't put enough on the phone such that I need to swap out the SD card. I can always download to my PC if need be. And I have a digital camera, so not really worried about running out of space due to photos. I understand this is a selling point. But don't think it impacts me that much.
I do want to thank everyone for chiming in. And I hope there is more information and more posts. Because all of this has been very informative. Thanks.
