Hi, Sorry to say this but this advice is wrong. The KIK app IS a battery eater and does cause your battery to overheat and drain very quickly. I am on my 3rd mobile phone replacement now because of KIK as i returned the other two back to vodafone as the battery got so hot and drained so quick. Some apps (not many) do do this to some Lumia phones and i truly dont know why.
My previous two phones had KIK on and it was awful with the battery, the third i installed kik when i found after a week of owning my 1020 and leaving in an as out the box state with no apps installed apart from the ones it came with. My battery lasted for 2-3 days with calls and texts to my wife and daughter all day every day. I installed KIK and nothing else. My battery drained in 9 hours without much use and with not using KIK, i charged it, used KIK the following day and it drained my phone flat in less then 2hrs use.
Its not the hardware, its the software.... KIK.
