Battery should cost around 5-10€ it is just small cell around 250mAh but get official replacement can be expensive. Sadly suunto talks about sustainability but there is not much profit in keeping old watch alive. Maybe thats reason for high unreal price (60% of watch price) to make profit.

@rdcritchlow I had a similar situation with 9baro, the battery was completely discharged in 10 hours. The discharge did not depend on activities, heart rate measurements or anything else. During diagnostics, a local unofficial service revealed a faulty charge or battery controller (I don’t remember exactly what it was) (the warranty on the watch had expired at that time). After replacing this element, the discharge returned to normal.

@DMytro thanks for info.I thought this is because I’m not running person

Is the first time I read that, specially with the car connection… But looks like it has to go to repair service… sorry for that.

[image: 1616788901048-suunto-5.png] This is my battery life. HR 24/7 enabled, sleep tracking enabled, bluetooth notifications disabled, vibration disabled, tones in button off mode. I did use GPS for 10minutes. I had one indoor activity with HR for 20 minutes. Once per day i synchronised with suunto app. Every day a played with watch around 5-10 minutes. Backlight was off 99% of time. So it looks i was too rush. Battery drop was fast only above 80% of battery. At around 80% i did soft reset. Maybe it helped to stop rapid battery drain. I am very satisfied with result.

@The_77 said in Strap replacement for S5: black one is still there I already bought from them also some stuff.
