Battery Age reset was added to the Android and IOS FORScan lite versions.

Yes. ForScan several months ago added many service procedures to their IOS and Android Apps including the Battery Monitoring System reset which zeros out the cumulative charge and discharge counters for the various states the car can be in. Thus, the algorithm can compute battery losses and better estimate the SOC of the 12 V battery. The 12 V battery age is also reset to zero and thus indicates how long ago it was reset from the current date. I don't know the precise 12 Volt Battery Saving algorithm but it seems that battery age (or accumulated battery losses), the current battery SOC, and the function (puddle lights, overhead lights, radio, cigar lighter outlet and so forth) affects the timing of shutdown of a function. Supposedly, these BMSs can extend the life of a battery by "smarter" charging and by cutting off power to devices after a period of time so not to discharge the battery too low which will affect the battery life or perhaps put another way, allow devices to operate longer without affecting battery life for the benefit of the user of the devices. My history: 1) June, 2015: Dealer replaced my original battery after 30 months in June 2015 and did not reset the battery monitoring. I did not realize this until over a year later. 2) March 13, 2018: Radio test was around 1 minute until turn off. SOC generally in high single digits, low teens. Battery Monitoring age (since it was not reset) was about 1923 days (about 64 months). But, replacement battery in June 2015 was only about 1000 days old. 3) March 13, 2018: Downloaded ForScan for Windows and got free extended license to do Battery Monitoring Reset. Reset battery monitoring and radio test was exactly 10 minutes until off. Over the next month or so, SOC climbed into the 50 - 60 %. 4) Today: Battery Monitoring age is 593 days but battery age is actually 1593 days old. SOC = 49%. Radio test = 10 minutes.
