Ranked in these QuestionsQuestion Ranking
Pro Epic battery
With a 5000mAh battery, this phone should have no problem lasting three full days between charges with regular use. Blu has even added the choice to charge other devices from the Studio Energy 2's charging port so you can top your friends phones up as long as you use the included adapter.
Pro Accessories included
In the box you find all the regular stuff (charging cable, wall adapter), but you also receive an OTG cable (for hooking up a mouse/keyboard/USB stick), earbuds. a soft plastic case, as well as a screen protector. This effectively reduces the price of the phone, as you don't need to buy any of these accessories as they are included.
Pro Good display
The 5" 720p display uses Amoled technology, which produces very rich colors and true blacks emit no light whatsoever. Most budget phones cut costs on the display, however the display is arguably the most important part of the phone as its the primary input/output device.
Pro Good performance for regular tasks
Performance will slow down while gaming, but it can handle regular tasks (streaming video, social media, web browsing) very smoothly.
Pro Dual SIM available
Some users need 2 SIM cards - perhaps one for calling and one for text. Other users use one SIM for business use, and the other for personal use. Either way, the option is here to have 2 SIMs active in the phone at the same time.
Con No tinkerability
Mediatek doesn't release the required information for developers to create custom ROMs for their phones. That means that they are very hard (if not impossible) to root, which many users do to access deeper software for a more customizable experience.
Con Thick and heavy
To fit the massive battery, the Studio Energy 2 is over 10mm thick and comes in at a weighty 176g on the scale.
Con Poor gaming performance
The Mediatek MT6735 processor has a weaker GPU than similarly priced Qualcomm equipped phones, which means worse gaming performance.
Con Physical buttons are not backlit
At night it is hard to see the physical buttons because they don't light up like most phones.
