What SCMDM factors affect device battery life?
• Connection type – Typical APN settings have short timeouts. These force VPN reconnections at short time intervals and result in poor battery performance. This is the most common (but not the only) reason for poor battery performance. Check the APN (Start – Settings -GPRS ) . You may be able to change to another provided by the ISP that has longer timeouts. • NAT KeepAlive frquency – If NAT is detected by the Mobile VPN, keepalives will be sent periodically (45 seconds). The period between keepalives is configurable. Because sending too many keepalive signals may significantly impact the battery life of the mobile device, it is recommended to contact the Mobile Operator and use a cellular data connection that does not require NAT or ensure that NAT inactivity timeouts have been customized for UDP.
