Quality of Experience (QoE) is proposed to evaluate user's overall satisfaction with the network system and services. For m-health systems, improving QoE means starting from user's view to make patients and doctors (the main users of m-health system who are especially captious to services related to health) to achieve best satisfaction. In this paper, we proposed an improved model for QoE of m-health systems based on energy consumption and information integrity received by the users, and then explore on how the users' satisfaction with m-health systems' energy consumption and received information integrity by exponential formula, which is influenced by the quantity of the transmitted information. Finally, from the results of simulation, we concluded that the appropriate compression of information quantity is the best way to improve QoE performance of the m-health system.
