Add Battery/Wi-Fi Status and Time
Different implementations may result in widely varying impact to the device battery life.
Part of this has been simplified in yesterday's OEM Agent upgrade with a date / time macro.
A major problem of using default macro on lockdown menu is that special codes need to be included to refresh the display at appropriate time. This is not a big problem for macro such as device name, as it is unlikely to be changed very often. However, for the %device_date_time% macro, the 'second' portion of the timestamp gets outdated as soon as it is directly displayed in the lockdown menu. Also, the format of the %device_date_time% macro is fixed and may not fit particular purpose unless post-processed with extra code. The new macro is, however, very useful and handy for use to create log entries.
