So I am already was a long time xiaomi redmi 1s user, and decided to upgrade to this 2gb ram model. And gave the 1s to my mom. I would have kept the 1s had I upgraded the os sooner but here goes a total vfm device with more internal memory space to take care. And a very much longer battery life!
Like someone else pointed out. The battery life is awesome. I have been using my bluetooth headphones and wifi a lot on this 1 week old device and havent charged for 1.5 days still is over 25-20% juice still left! Te feature I dont need to point out, you can find them online and on youtube reviews videos.
