Usage Battery Optimisation
uTag tries to use as little battery as possible, while maintaining functionality for SmartTags. Below are a few steps and tips to help preserve battery life when using uTag.
This is the time between location refreshes for currently connected Tags. Increasing it will mean that Tags you own and are connected to update less frequently, but your device's battery will be used less. If you leave your Tag behind, you will be reliant on other Samsung devices to update its location - so a longer refresh frequency may mean that the last location from your device is less useful.
If you live in or are travelling in an area with lots of Samsung devices and leave your Tag behind, this option will make little difference, other than how often the location updates in uTag while the Tag is connected to your device.
This is how old a location can be during refreshes. A higher value means that your device will get a location less frequently during location updates (saving battery), but the location may be outdated. A lower value means the location will be more accurate, but more battery will be used.
With this option enabled, other Tag's locations will be sent to the Samsung Find my Everything (FME) network. If your Tag(s) are not nearby but others are, this option will use more battery since location updates will be sent for those Tags.
If you have widgets added to your home screen or lock screen, this option controls how often the map on them updates. Updating the map uses processing power, and thus a higher refresh frequency uses more battery.
If a Tag is in Passive Mode, uTag is not actually connected, and therefore less battery will be used maintaining the connection (this is only very marginal, however, and is impacted by the overmature offline option below).
If a Tag is in passive mode and this option is enabled, uTag will periodically connect to the Tag, before immediately disconnecting again. This uses more battery, but not as much as maintaining a connection.
