@Rogerio-Macedo is your watch new? This issue was solved with a software update in January.

What happens if you connect it to your computer and start Suuntolink?

@zeboz unfortunately it is not there, not even is S9 line. I don’t expect such an update for the Spartan series.

@Alex-Charles Have you ever tried to contact support? Maybe there is something defective. In fact if you say " to use “best” accuracy which does not even exist anymore in the menu" maybe there’s something wrong. Did you check power saving menu ? Do you have the latest firmware ? I use GPS only and I never face drift that can let me say that the watch is unusable … HR(if you meant OHR) it’s a different topic. It could simply not work for you.

@richard-j-adams Well, incredible as it sounds, Suunto does not look like is willing to invest in proper structured sessions like the one you described, even though previous models had that available. Right now you can program that “simple” session in some other brands, but not with Suunto. Don’t even think about asymmetrical intervals or ladders… I would say the nearest you could set is a 20x50m with 30” rec time interval training. You would be able to do warming before the exercise (you would press start the exercise once you are warm and ready), and after you finish you would have free run, but you would need to know how long you have been running after the interval training and that’s usually hard to do without reading the watch face.

@dragan-petrovic Huawei in general is very hard in saving battery and therefore killing apps and functions. you can try to setup you battery or power saver to exclude Suunto App from being restricted

@isa4d could be defective, but before you contact Suunto support try another cable and another computer for the update. Also try drag and drop a firmware zip file instead of the Suuntolink download seemed to help for some people.

@שרון-כהן can you try with a different computer or a different cable?

@richard-j-adams fpo is full power off.

@aleksandra-czerepak Maybe, who knows Did you check if the activities (watch) shows graphs (hr, altitude etc) If graph are missing it means the watch miss the “complete” activity but has only a summary and it’s not sending it to the phone.
