only about 12% of the time, the smartphone is in power saving mode. the vast majority of the time the device is using cellular. whats interesting is that the 4s has more of an average on both active and idle times than the 4. i am sure its an anomaly, but its something to keep an eye on. as a result, the 4s at a higher battery status, has much better capacity utilization. if the devices were able to do this at idle time, but the 4 couldnt, the 4s would have a better overall average capacity.
the 4 was never great at capacity, and the iphone 4s isnt much better, but it still has a leg up on the 4 on average and at the high and low ends of the utilization spectrum. so it seems that the 4s is still improving over the 4, and, having high capacity utilization, is still a legitimate contender. the 4s deeper battery should help its battery longevity if this claim is true, which seems to be backed by some random forum posts out there.
remember that all of these devices are on hspa+ networks, and the 4s often surpasses hspa+s theoretical maximum of 14.4 mbps. this is thanks to peer to peer tech and the fact that the 4s can get a bit better with that type of receive diversity. its a pretty good angle to approach this from, and it seems like it could be a one of the main reasons for the sudden and sharp improvement in 4s speed. that, and the over 4x better antenna. which brings us to the next part of the story.
on at&t, the iphone 4s and the galaxy s4 both have significantly better than average speeds of 3.45 mbps. the iphone 5 seems to be dropping behind at a rate of 1.51 mbps per carrier. this would seem to indicate that its a little more difficult to get speed on at&t.
some of the speed increase is from the addition of the wcdma radio. it is mostly just an lte radio that operates on the same spectrum as wcdma. its not a cdma evdo rev.a radio, its just a wcdma radio that operates on the same band. it is also a faster radio, but we didnt see a huge difference in speed, probably because its not getting used in the 4. the other reason for the speed increase is the new baseband that comes with the 4s. with line of sight to an at&t nodeb inside my hspa+ market im used to seeing a maximum downstream throughput on the iphone 4 of almost exactly ~6.1 mbps, which is about right for the 4s hsdpa 7.2 maximum when you include overhead. the nice straight line in that result should clue you in that downstream throughput on the 4 was being gated by the baseband. on the 4s, in this same location, ive been able to get 9.9 mbps when the cell isnt loaded at night (i didnt grab a screenshot of that one, for some reason). its nice to finally not be gated by the baseband anymore on an idevice. having a faster baseband is part of the reason the 4ss cellular performance is much better, the other half is receive diversity which helps the 4s push these high throughput rates, and also dramatically improve performance at cell edge. the previous x-gold 618 baseband was a nice improvement over the iphone 3g/3gs x-gold 608, which lacked hsupa, but in a world where most wcdma carriers are at least running hsdpa 14.4, its nice to finally have an iphone with something faster than hsdpa 7.2. ive done lots of testing inside my tucson, az market (which is 4g hspa+ on at&ts coverage viewer ) with both the 4 and the 4s, and have built a very good feel for the 4s performance. as a reminder, if youre in the usa, those dark blue areas represent hspa+ coverage areas with at&ts upgraded backhaul. in practice these are at least hsdpa 14.4. 5ec8ef588b
