I have purchased the Moto G for 12 k and I have been using almost 2 years with minimal or normal usage.
it has been performed well for one 1.5 year well, after that it has been down drastically, it takes much time while running without net as well and if we use the net the performance was very poor.
so I thought to purchase I phone it will give best performance if I go additional 5k added to go with I phone 5s.
will give at least 4-5 years.
