Samsung Galaxy Mega 5.8 VS Samsung Galaxy Mega 6.3 Comparison Review

Samsung has literally introduced a new category of phones with their Mega series. These phones are bigger than your usual ‘phablets’ and smaller than tablets. The two devices launched in the Mega series by Samsung in India today are the Mega 5.8 and Mega 6.3. The model numbers also suggest what screen size the devices would come with, which is 5.8 inches and 6.3 inches respectively.


At the moment, there is no competitor offering these screen sizes in the market, so the Mega series will be the only option for people looking for such devices. You are interested in buying one of these, but are confused as to which one to go for? Here’s our comparison review between the two which would help you choose one among the two.


Processor and Battery

We would have liked to see quad-core CPUs on these devices but Samsung has opted to go with dual core processors on both these devices. The Mega 5.8 comes with a dual core 1.4GHz processor while the Mega 6.3 comes with a more updated 1.7GHz processor, which again is dual-core. Worth noting is that both these devices will be based on the Cortex A15 architecture, and will have the Exynos 5250 chipset.

This means that the Mega 6.3 is the clear winner in terms of processing power, with a faster processor. Both devices come with 1.5GB of RAM, which is rather unusual to see in phones today. But the 1.5GB should provide for some smooth multitasking, and we expect the user available RAM to be in the 800MB range with the Android OS taking up the rest. In terms of storage, the Mega 5.8 only comes in an 8GB variant, whereas the Mega 6.3 comes in 8GB and 16GB variants.

The Mega 5.8 features a 2600mAh battery which should take you through one day pretty easily. On the other hand the Mega 6.3 comes with a massive 3200mAh battery which would take you probably more than a day to drain out. Also worth noting is that the screen size difference is 0.5 inches diagonally, but the difference is battery is quite a bit so we expect the Mega 6.3 to give you a better battery life.

Quite obviously, the Mega 6.3 beats the Mega 5.8 in terms of processing power and battery, only if you can live with a bigger screen.


Connectivity and Features

Connectivity features on both these devices are more or less identical, with both devices having dual-band WiFi, WiFi direct, WiFi hotspot, Bluetooth v4.0, 3G, and USB. The Mega 6.3 has support for USB OTG (On The Go) and MHL as well, which means you can hook up your USB and HDMI devices to the phone any time.

Both phones have an 8MP main camera, which is capable of taking pictures up to 3264 x 2448 pixels in resolution, and comes with autofocus and LED flash in aiding the user. The 8MP camera also supports HDR. The front camera, on both the Mega devices is 1.9MP which should be good enough for video calls. Both devices come with Android v4.2.2 Jelly Bean installed, which means you get the latest Android OS. As it is with Samsung devices, you will see the TouchWiz overlay on both these phones.

There is nothing much to choose from in between the Mega 5.8 and Mega 6.3 when it comes to connectivity and features, but the Mega 6.3 has an edge over the Mega 5.8 thanks to the addition of MHL video output and USB OTG, which we think are important features.

While there is nothing much to choose from in between the two devices, the Mega 6.3 will definitely prove to be a better contender in the long term. Why? Because of a better processor, OTG and MHL support. Of course, you have to pay about 6000 INR extra, but all the added features should make your device a bit more future proof. In the sense, that there is no point in buying a device which offers specs less than today’s average. Going by the press release issued by Samsung, the Galaxy Mega 5.8 will be available next week for 25,100 INR, while Mega 6.3 will go on sale around June 10 for INR 31,490.
