I'm curious about switching from lte to 3g, will i really save any battery? Or do I need to install a custom modem?

Lte and battery power

i get my best battery life on lte. i had the n4, it doesnt officially come with lte, but can be enabled. anyways, as soon as i started using lte on my n4, i gained an hour of screen on time as opposed to using 3G(hspa+). i want from 4 hours screen on time, to 5 hours. and on my nexus 5, i use lte exclusively, i dont even ever use wifi, and i see 5-6 hours screen on time every day. then again, it would depend on your signal quality.
In my house I have 4/4 bars signal with H and 2/4 bars with LTE.
In that case LTE is still the best option?

it can be. generally, when using data, lte is more efficient. it spends less time downloading/uploading, therefor uses less battery. if data speeds are better using lte than they are with your 3g, then lte would be better to use.
The fastest connection with the best signal should save you the most battery.
Wifi is much shorter range so needs less power to maintain a connection. Considering most people have fast Wifi it will usually be the most efficient.

I had the best battery on LTE when I went to London for a few days. Gained a hour screen on time easily with very strong coverage throughout most of central London apart from the underground obviously lol

i did an experiment on lte/3G battery life in the trinity thread a few days ago, same usage and setup. on lte i had 5.5h sot, on 3G(h/h+) i had 4.5h sot. using lte gains me an hour sot, using 3G i lose an hour sot.
When using a 3G connection does it constantly jump between 3G and H+ for you also? Seems to be based on load and I'm assuming normal operation.
I need to keep testing this but lately I am finding 3G/H+ (7-15Mbps) connection to be similar in battery use to my older wireless G (15Mbps) network.

for me it jumps from h to h+ when i access data, but thats how its supposed to work. the 3G/H will be used when not needing to access data, H+ will be used when accessing data, unless H+ isnt available. besides that, it doesnt jump back and forth at all.
In my case I'm having better battery with HSPA than with LTE.
The thing is...here in my house I have yellow/brown 4G signal and green 3G signal.
In a long deep sleep time (at nights) 4G consumes a bit more than 3G.
But during the day the difference is a little more significant.
I can get 4 hours of SoT with 3G. But 3 hours with LTE (or 3 hours and half).
I'm pretty sure that with a perfect LTE signal I would even have better battery life (like almost 5 hours of SoT).
But here is still experimental.
