I bought micromax canvas A311(micromax nitro) before 1 and half year.and believe me I didnt go in custom care at yet.its processer is pretty good.it has 2GB ram.in now time there are many phones which have 3GB or 4GB.in price list.this is medium badget phone.but in market 3GB or 4GB phones are very costly is compare to this phone.so this phone is good.i very liked it.but if you increase the battery life of any phone.so you charge your phone by your comoany charger which you got with your phone.in my point of view if you buy low badget phone.so dont wait for other phones.and buy micromax canvas nitro.
THANK YOU.!
