Coolpad Mega 2.5d Is an average phone for an average user.
Lets Talk about its key points
Screen resolution: Its 1280*720(267 ppi) screen looks just fine, pictures looks crisp and does enough justice to tht HD videos
Battery: 2500 mah is quiet sufficient if you are an average user(less gaming), should easily last a day without any trouble
RAM: Out of 3GB you will only get about 1.5-1.7GB free for your usage( Due to the pre-installed apps running in the backgroud). But thats the case with every smartphone in the market
Camera: The back camera boasts a 8Mp shooter which works perfectly fine in daylight but disappoints in the night( Flash dosent do much good here) . the selfie camera is quiet impressive, a front flash would have been a cherry on the cake.
Overall The phone is quiet good for daily usage. The only thing that concerns me is the hybrid sim slot, gets really difficult to manage with only 16Gigs of space( U get only 11gb free). The 5.5 inch Handset feels really good at hand and the build quality is also quiet good. totally worth buying if You can manage with the Hybrid Sim thing .
