Along with what FURRYe38 said, much is dependant on your phone and its capabilities. If you think about it, most phones use a 1x1 antenna. Some have 2x2 but the average phone is more likely to be a 1x1 configuration.
The C7000 in 2.4ghz can do 200mbps over a 1x1 antenna arrangement with 256-qam if your device has that capabilites. Many devices don't as its a non-standard extension to wireless-n. If your devices is a 64-qam device its going to connect at 150mbps over 2.4ghz (probably). Which if your getting 70mbps is pretty much optimal. Frankly, thats pretty good. I've got way to many 2.4ghz networks in my area and struggle to get past 30-40mbps for any stretch of time.
Your 5ghz potentially could be optimized a bit but again, a lot depends on the device and your setup. 5ghz doesn't have as much penetration capabilities and can't transmit as far.

Is there a reason you want faster speeds on a phone? Most 4k streaming maxes out at 40mbps and its usually the phone that's the bottleneck on tasks when you get past a certain download/upload speed. Even netflix only needs a 25mbps for ultra HD.
