I've tried several spying applications and the most common problem among these apps is that the battery is depleted within hours after charging. Haven't found this problem in Xnspy though. I installed the app on my spouse phone to check how well it works. The app gives live location and everything that happens in real time. I was also able to record the surroundings of the phone when it was in idle mode. You can also control the phone with commands sent from the app as well. You can block apps too. It's a complete spying app and some very amazing features.
