Lenovo k6 power dont buy this mobile. At first it will be good but after using for 20 days r more u will start facing problems. My phone gets hang and screen will off suddenly.one day my phone stopped working I can’t able to restart r switch off also. After contacting service center they formatted my phone nd gave. But still my phone offs suddenly. I even have heating issue problem. Sometimes if I use my mobile for 10 min its gets heated too much. Nd battery life is also not much good they say 4000mah but it doesn’t perform good.My phone battery lasts only for one day and I dont use my phone very often.
