发帖数: 375 | 4 Dude, where did you get this info that 3G is only slightly slower than 4G?
In general, 4G should be much faster than 3G in terms of both latency and
throughput, period.
Also, in IDLE mode (most phone stays in this state), 3G and 4G are almost no
difference, maybe 1mA difference. In active mode, 4G could consume more
power than 3G, but considering the time saving (for example downloading a
big file), there are not exactly too much difference.
All I am talking about in the above is for general user experience. Of
course, the network coverage in different places might cause different user
experience. So if you have a good 4G coverage, then you should definitely
turn on your 4G.
One trick to see the difference on HTC EVO, just turn on your 4G on and off,
and see how your youtube behaves under 4G and 3G.

4G: peak speed 12Mbps, but in practice, you get 2-4Mbps
these numbers are consistent with those reported on sprint user
forums.
4G is better but, depending on personal views, I won't call it
breathtaking over EV-DO Rev. A
4G?
