The moment watch is charged, battery drops by 10%, this happens repeatedly. Spartan trainer.
Battery life how to put it… Isn’t great in any case, so now even worse, since I assume the real indicator is the lower one. -
There are several discussion about this, try to search it.
You probably need to calibrate the battery

@sartoric what do you mean by calibrate the battery? Where is that even an option?

@Droro this is the reply i got a while back from suunto…
"
The difference of battery percentage shown when charging cable is connected or not (and also in different modes too), is because Trainer does not have separate circuit to validate battery level. Instead the calculations are software based, and they are not as accurate as the calculations with a separate circuit/chip. Therefore, there is a slight variation observed in the battery % when the watch is on charging mode and not." -
@giraffe73 nice. I mean nice of them to reply and not give you some generic answer.
The trainer battery is not as good as published from my own experience… But its not the first company that does this.
