No one is suggesting that. They are just saying the rectangle they first thought was RAM is probably a flash device.
There are very limited deployments of LTE Advanced currently in the US but on a phone its pretty much useless outside of a speed test. And with data caps on most carriers even a few speed tests at that speed will eat your data allotment.
Most sites/services can't even give you the content as fast as LTE Advanced is.
Yeah, a weak signal drains the battery really fast.
I think there's room for improvement in the baseband chip, but it also a matter of antenna.
There was nothing flippant in communicating that he was wrong and I stated that ram was faster then flash.
You should turn LTE back on considering its more battery efficient than 3G. That and you're already paying carriers for it.
I find 3G to be more battery friendly, I turn it off (LTE) when I go to bed at night, or I know the phone won't be accessed for a period of time.
Really, I'm talking about consuming double the battery of 3G. I live in Amsterdam and maybe the coverage is not the best, thus switching a lot from tower to tower thus degrading the battery, but it is still my experience.
There isn't much Apple can do about that. Building penetration has to do with the frequencies used. Lower frequencies (700, 750, 800, 850 MHz) get much better penetration than high frequencies (1700, 1900, 2500 MHz). Each carrier has different frequencies that they licensed from the government.
I understand you're nit picking, but isn't it really understood at this point that when discussing consumer data rates we are discussing bits and not bytes?
The answer would be no. You cannot replace volatile with non-volatile, as I have recently learned. The number of reads and writes on volatile are many multiples higher than nonvolatile and if nonvolatile was attempted to be used in the manner it would quickly burn out within a matter of hours if not minutes because nonvolatile has limited writes.
Perhaps the signal isn't strong and the phone keeps pinging for towers. My experience has been LTE is more power hungry.
It would be considerably more slow and wear out the NAND memory which can only be written to so many thousands of times.
my ipad air goes from 100% to zero in about 4 hours of using 4g, as I found out while I was on vacation.
Yeah it sucks. I am in the UK and am lucky to just about get a 3G signal, no 4G towers near me and I doubt there will be. In the UK they really only bother with city's and motorway's, anywhere else the operators don't pay much attention to. I haven't even bothered with a 4G contract because of this even though they are pretty cheap for us.
Like you said, it probably improves overall latency when doing small requests. You can have more services in the cloud that way. Web pages these days are huge and you need a decent bandwidth just so they don't take a few seconds to load like in the 1990s.
Its certainly not because you need to have that mount speed to watch a few 4K streams on your cell phone ;-).

You can see the new antennas in almost all larger cities in the EU.
It's entirely dependent on the particular hardware you're using, but everything else being equal, the faster the modem can complete a data transfer and put the radio back to sleep, the less power the device will use. Current generation LTE modems are way more efficient from both a spectrum and power perspective than the older 3G only versions. Some newer devices also include an envelope power tracker that actually varies the voltage going to the power amplifier to match the waveform of the transmitted signal, saving even more power. However, some early LTE implementations employed 45 nm SoC's paired with discrete modems which tended to use about 50% more power on LTE than 3G.
I turn bluetooth off because I never use it. I leave Wi-Fi on all the time (but only have it set to connect to trusted networks), because it is more efficient than LTE and doesn't hammer my data plan. I can't imagine ever intentionally disabling LTE. The latency alone on 3G would drive me postal if I had to tolerate it more often than I absolutely have to. If you look at Anandtech's web browsing battery life tests for the iPhone 5, it lasted 4.55 hours on 3G, 8.19 hours on LTE, and 10.27 hours using Wi-Fi.
If I had to hazard a guess, it sounds more like you're having a problem with a particular application constantly waking the modem, and if 3G is draining the battery less, it's because that application behaves differently when you're on 3G, or the modem is able to better coalesce the transfers for whatever reason. Or you're using an early LTE device that had one of the first gen discrete LTE modems.
