There are a few problems with 4G at the moment, however. Firstly the network coverage isn’t very good. At present EE's network only covers the major cities, so when you're outside of those big urban areas you're going to be back on 3G or maybe even Edge. Secondly, even in the areas where the EE website says you should get good coverage, signal quality can be pretty patchy. My area was marked as having good coverage on the EE website, for example, but I found in reality it was actually very mixed. Indoors I got one to two bars of signal when the phone was connected to 4G, but even at that the handset tended to skip between connecting to the 4G and 3G networks seemingly at random.
Outdoors things improved a bit with three to four bars of coverage, I noticed that speeds weren't necessarily fastest when the signal was strongest, Often I got the fastest speeds when I was getting middling reception, which seems strange, In terms of raw speed, though, if you've got decent coverage, 4G really does deliver a massive jump over 3G, as getting over 20Mbps download speed on a mobile phone is fast in anyone's book, The S3 LTE packs the same battery as the standard S3 -- a 2,100mAh power pack -- and it's removable, unlike the battery on the new Nexus 4 or the iPhone 5, Unfortunately, battery life does seem to iphone case video game suffer quite heavily due to the addition of the 4G support, though..
While streaming The Lives of Others on Netflix over 4G, for example, the battery went from full charge to 38 per cent over the 2 hours and 17 minutes of the movie. On the standard S3 running on O2's 3G network, the battery went from full charge to 50 per cent completing the same task. Although the two are not strictly directly comparable as they're running on different networks, the signal strength was similar so it does give an indication of the extra battery drain that 4G places on the phone. Even in more general day-to-day use, it was quite noticeable that the 4G was much tougher on the battery. It usually struggled to get through a full day without needing to be topped up with juice. The standard S3 on the other hand, would happily last a full day when used for similar tasks.
The problem seems to be that the LTE version has to do more polling of the network to find a 4G signal, and that's something which tends to eat up a lot of battery life over the day, I can’t help feeling that Samsung should have gone for a bigger battery in this iphone case video game LTE version, even if it meant making it the phone a tad thicker and heavier, The S3 LTE looks almost identical to the standard S3, It's got the same rounded corners and curved back where the camera on the rear sits almost flush with the battery cover, It's a very wide and tall phone, thanks mainly to its massive 4.8-inch screen, but it's also extremely slim measuring just over 8mm thick, The phone also feels very light, but this is partly due to the fact that its chassis is made mainly from plastic, something which makes it feel a little less premium than you'd expect of a blower of this price..
The only outwardly noticeable difference between this model and the standard one is the LTE logo stamped on the rear of the phone and its titanium hue. The latter helps it to look more professional and upmarket than the standard S3, but the difference is so small as to be almost negligible. The phone runs Android Jelly Bean, which is the latest version of the operating system. Google has done a lot of work on speeding up the user interface in Jelly Bean, making the Android experience much more pleasant and intuitive. It no longer suffers from the annoying stutters and pauses that afflicted previous versions of the OS -- even when they were running on very fast hardware.
