It confuses me when people say that LTE is pointless/stupid compared to 3G because it uses more battery life, makes you go through your data plan faster, and because it only makes a difference when downloading data/content (which is a VERY good thing in and of itself -- would you rather an app take 5 seconds to download on LTE as opposed to 3-5 minutes on 3G?) and that it's not worth it. This is simply
not true.
You won't only notice the speed increase that comes with connecting to an LTE network in just your downloads, you'll notice it in any app that requires you to connect to the internet. I'll give some examples (and I've seen the difference first hand when comparing my iPhone 4 to my HTC Thunderbolt that connects to Verizon's LTE network):
Checking Email: Your emails will download faster, images and attachments and text will all be downloaded MUCH faster over LTE than on 3G, allowing you to read your emails and reply to them quicker.
Web Browsing: Web pages will load considerably faster over LTE than on 3G, and websites that display a lot of content and images like
The Verge or
Engadget, for example, will load much, much faster over LTE.
Using the Facebook and Twitter apps (possibly important for some): Refreshing your news feed/timeline's will be done almost instantly over LTE as opposed to your waiting 10+ seconds for it to load on 3G (I've tested this many, many times and the difference is night and day). Say you're reading your newsfeed and you click on a picture you want to look at. On 3G, it might take 20-30 seconds for it to load, while on LTE, it'll be done in 1-2 seconds.
All of these things makes the experience of using your smartphone FEEL faster to the user, thus making it a more enjoyable and less frustrating experience. So, no, it's NOT true that you will notice the speed "only when you download things", you'll notice it EVERYWHERE! People today are so connected to the internet that they are CONSTANTLY downloading information (for those that are unaware, going to a website in your smartphones web browser requires it to download the images, text, articles, etc. from that website in order for it to display on your phone, so the faster the speed of the network you're on, the faster your page loads and this means less time waiting for a page to load or a video to buffer).
Think about it: What do most people use their smartphone's for? Checking the web and email, downloading new apps, checking facebook, checking twitter, sending pictures and videos on facebook and twitter... This is probably 90% of what people do on their smartphones, with the other 10% being texting and actually using the phone as a phone. All of that checking requires your phone to constantly be downloading and uploading data. LTE makes a world of a difference. You really have to use it yourself to believe it.
Hope this helps people understand the difference that LTE makes when compared to 3G or HSPA+ (4G as AT&T and T-Mobile call it even though it's still 3G).
