I bought this phone 7 months back, with 1.5 gb ram and 16 gb internal memory which way too much to use and I never neeede a memory card for this phone. Since from 7 months its running very handy, and I also upgraded it from kitkat to lollipop, after the update its has become more faster and more handy. Battery backup is way more than I expected.
When I charge my phone with 100 % battery it runs atleast 14 hours in 3g mode when I keep it in power saving mode. It has also ultra power saving mode during the peek time which gives you couple of more hours of backup. When I dont use internet it runs 24 hours ! Its front camera is very good even iys 5 mp. The best part about the phone is its slimmest I ever had one !
