This then requires less processing power and will provide more battery life. One simple option is to encode it to a lower level of encryption, such as 128-bit. Realize that there are some options in terms of this encryption and decryption process that will impact smartphone battery runtime. Most services encrypt it via a 256-bit algorithm, which meets government standards for “Top Secret,” yes like in the spy movies.Īs you would imagine, this does involve some heavy duty math via an encryption cipher to send it via the tunnel, and also to decode it at the other end. The VPN service keeps the data safe by creating the encrypted tunnel between the VPN server, and the client device. This part time use of the VPN is a more balanced approach, with the use of the VPN when needed, without incurring the battery life penalty at all times for the data transferred which these smartphones constantly do. This is to toggle the VPN connection on whenever it is needed, say to secure a financial transaction when connected via public Wi-Fi, and then to turn it back off when doing something less sensitive, such as watching a YouTube video. While some would advocate for using it whenever you are online, for those that wish to prioritize battery life there is another approach. Using a VPN connection does have many benefits, such as security and privacy. This is due to the fact that Wi-Fi is a lower power connection to a cellular one, and therefore affects the battery life less. In addition to the benefits of using less data on your monthly data plan, and also the generally faster throughput speeds, there is also one more - battery life. However, when at home, work, your local library, and the coffee shop, it is worth the effort to connect to the wireless internet connection. When out and about, there is little choice mostly to use the cellular connection. Connect to Wi-FiĮvery smartphone has two ways of connecting to the internet: the cellular modem, and the Wi-Fi. After all, nobody wants to end up with a battery depleted device. Now that we have identified the problem of VPN battery drain, let’s look at some ways to address it.
