Typical usage is based on a school day with 6 sessions of 5-minute gameplay, 10 messages, 3 one-minute voice calls, 5 location checks, 2 payments and 4 hours with Wi-Fi connectivity. Battery life depends on features enabled, usage, environment and many other factors. Use of certain features will decrease battery life. Actual battery life may be lower.}
