That’s correct, my Xolo Q1200 which has non removable battery, The battery got swelled up just in less than 2 months, even after not exhaustive usage. Its just their cheap batteries in xolo phones, though my phone is in warranty I still have to pay for the battery and services. Xolo care doesn’t really care. Xolo care staff is not actually a group of technical Team, consider it a collection point, all that they do at xolo care is resetting or formatting the phones, things that can be done own our on. They are not professional, don’t even listen to the problems. They don’t treat Xolo as something of their own, they would treat customers like any Gaffar Market roadside shopkeepers. They would even ask you to get your phones repaired outside from local Dukanwalas. Xolo Phones are basically like those Desi Jugaads, if they work, they work real good and for long time, but if in case something, even a small issue, happens to your phone, You are definitely going to be left with a very bitter taste in your mouth with excessive sense of loss to have bought this product. This is the difference among already established Brands like Nokia or Samsung, and still-emerging Brands like Xolo and Karbonn.
