[Smart Battery Module] Update for greater accuracy

apps/smartbatt/ChangeLog

@@ -1,3 +1,4 @@
 v0.01: New app!
 v0.02: Add dynamic intervals, depending on total cycles recorded
 v0.03: Return more data inside of .get();
+v0.04: Return to fixed update intervals, added setting to change update interval, limit cycles to 60 for greater precision over longer period of time

 ## Settings
 ### Clear Data - Clears all learned data. 
 Use this when you switch to a new clock or change the battery drainage in a fundamental way. The app averages drainage over time, and so you might just want to restart the learned data to be more accurate for the new configurations you have implemented.
+### Update Interval - The time that the module should record battery drainage
+This changes the interval when you record battery drainage. Generally, a longer interval means more precise estimates, at the cost of quick updates.
+
+Min: 30 minutes
+
+Max: 48 hours
 ### Logging - Enables logging for stats that this module uses. 
 To view the log file, go to the [Web IDE](https://www.espruino.com/ide/#), click on the storage icon (4 discs), and scroll to the file named `smartbattlog.json`. From there, you can view the file, copy to editor, or save it to your computer.
