I bought Lenovo A6000 plus 9 months ago from Flipkart.
I bought it on the price Rs7499 and it was a great value of money. I am using this smartphone since last 9 months and till now it is working fine, I havent had any issues with it.
It is a 4G device and I am using it my Jio Sim Card and is working fine and with great speeds also.
It has got a 2GB ram which is quite good for running some good games like Asphalt 8 and many others, it also comes with 16GB internal storage out of which 11GB is usable. It has got a 1.2Ghz QuadCore processor and is good while doing multitasking.
It has got a plastic casing which a bit slippery overall a good design and a nice finish. Its rear camera is nice to take pictures at day time but the front camera is not so good.
Its has got two Dolby speakers which provide a good sound experience and a 5 inches screen size with 720p resolution which is quite good.
The battery is 2100 mAh which darins very quickly since I have upgraded to LOLLIPOP 5.1 and I need to charge it in a few hours.
Over all besides the battery backup the phone is good and great value of money.
