Battery drain after 2+ years of use.

SuperFlo75

I also have my SV since may 23 and I‘m still happy with it… I noticed a little bit more battery drain after the latest firmware update and after I changed to another watch face (UTMB watchface)… I did this the same day… and after that, the battery consumption was a bit higher… but I think this was due to the changed battery save settings after the update… after checking out all settings it seems to be like before

@gone-troppo Yes, load to 100%, discharge to zero (really, until the watch shuts down) and then charge to 100% again. Especially after a firmware upgrade the battery logic goes crazy and needs to be resetted that way.
You will see if thats the problem when you try to discharge completly. It should stay on 1% for a looooong time. Thats the most annoying part of the procedure as you cannot use the watch in this state

What have changed and what are your settings?

from where this info comes?

@Stefano-M64 I got it somewhere here in the forum, I think during a firmware upgrade last year. Since then I had the procedure 3 or 4 times - always with consistent battery behaviour afterwards

One cycle of charge after update on my SV, battery drain is around 2% a day without activity.

Those 20-80% ideas have no real advantage for today’s hardware.

If lithium-ion/lithium-polymer batteries are today’s hardware, premature battery aging due to high cell voltage is definitely a real thing. That’s why many devices have customizable cut-off limit for cell charging.

Those experiencing decreased battery capacity due to aging, under warranty, or even out of warranty battery replacement is an option to consider, depending on the severity of capacity loss, price, and estimated turnaround time.

Yes and no.

Yes 0-100% ages the cells faster, which is relevant in a smartphone scenario where the phones are charged almost daily, and where a 20% capacity drop means you have to recharge it a 5 PM.

However, in our watches, the cells are rated for 300 cycles, which is not a lot, but once you factor in that you charge your watch every 2 weeks, those 300 cycles gives you 600 weeks, or roughly 11 years before your battery reaches 80% capacity (more likely 8 years factoring the degradation due to ageing), but at that point you still have 10 days of battery life.

So my two cents is to not bother, charge it when you need, and remove it once you think about it again.

@JonasLarsson my settings are:
Helligkeit niedrig (brightness low?)
Stand by off
Licht durch anheben niedrig (raise to wake low)
after updating, I had stand by on, brightness high…

Thanks. I have Medium/Standby off/High.

Hey mate nah it’s been like this for a while. Haven’t tried hard reset. Going to try drain to 0% and charge to 100% first like a few here reccomended.
