I have used Micromax Q7 before.
MAN what a phone! I used it for about 1 year but my use was too rough, but boy, this phone was also really tough! Dropped and smashed plenty of times, it just wont give up! It never really stopped working, except lately its track ball stopped to work.
Cant say anything about superfone/ninja series. Lets see.
Anyways whats the battery backup on A87 with real life conditions?
with 2-3 hours of web browsing over wifi, some video watching, it would last for 1.5 day. As its a dual sim phone, dont expect much. Just charge it at the end of the day.
Also should keep in mind that in my college, the network coverage is very very poor. So mobile has to continuously search for signals for two sims. It would drain too much battery power.
