S7: the State of Google Wear OS

[Robert André Karlstad Gråwe]

I think NickK is fairly on point with this.
But i would forgive all of this if the battery life was double what suunto states.
As it sits, you’ll have to recharge it every other day for the first 6 months, then you’re going to start to run out of juice because you recharged it every other day, and now the ball is rolling down a hill and suddenly you will want to send it in for a battery replacement.
That’s what is happening to my suunto 9 baro, that’s what happens to your smart phones aswell, you all complain to apple or whatever that the new updates are killing your devices, planned obsolence you call it, forgetting that you charged the device every day since it was new, and now it has 365 charge cycles on it and capacity has dropped 30% because that’s batteries for you.

A bigger battery will make this problem less problemy.
As i see it, a samsung galaxy watch is a better purchase if you want it to last, tho the suunto 7 obviously looks way better it will not be able to compete on batterylife, and the galaxy watch also has lte and working spotify.
The only downside is that it uses samsung health, wich isn’t half bad but it’s not suunto or garmin.

@Robert-André-Karlstad-Gråwe the 365 circles etc wont solve with a bigger battery.

Nor can one say that 365 ciclres will impact 30% the battery life

[pilleus]

Charging a smartphone or smartwatch once a day is reality for most users. And a big problem in all the countries with electricity only twice a week.

[pilleus]

My old Sony Smartwatch 3 and my old Misfit Vapor have both more than 1000 charging circles and no significant change in battery life. And during long activities with GPS I charged the devices on the fly with a power bank. Not comfortable but a solution.

And if Suunto 7 is able to record 7 or 8 hours with GPS without changing it is comfortable and twice the time of the old devices.

Out of curiosity: what are the expected battery degradation stats for the S-series watches?

@Dimitrios-Kanellopoulos
Really?
Look, i’ve worked with lithium batteries for 10 years now, it’s also part of my hobby and i’ve burned trough enough of them to know.
I have logs of my batteries on my charger that tells me what state they are in and how many charge cycles they have done.
Capacity goes down with charge cycles, and the more times you charge them the faster capacity drops.

The typical estimated life of a Lithium-Ion battery is about two to three years or 300 to 500 charge cycles, whichever occurs first. One charge cycle is a period of use from fully charged, to fully discharged, and fully recharged again.
Here’s a link to an article about lithium batteries and how to prolong it’s life, and i think you’ll find that capacity drops quite rapidly.
Hence a bigger battery will last longer as it needs less charge cycles.

@Robert-André-Karlstad-Gråwe and do bigger batteries don’t suffer from this? (at least to this I replied).

@Robert-André-Karlstad-Gråwe
It largely depends on temperatures and the maximum and minimum voltages where charge and discharge switches off (if you use only the middle percentages of the battery they last way longer than with always fully depleting it, etc)
These effects are way bigger than just time or charge cycles for LiIon

My last phone, which I was charging everyday plugging it at evening and unplugging it in the morning for more than 2.5 years still has more or less the same initial capacity, I haven’t noticed any deterioration. My wife’s Nexus 5X still can last two days with the same initial conditions, more than 3 years ago, yes 3 years.

I think battery issues are quite controlled now a days.

[isazi]

@cosmecosta my Nexus5X lasted two or more days for a couple of years, but then the battery got worse and I was lucky if I could get a full day out of it. But, as always with these things, YMMV.

[Dimitrios Kanellopoulos]

@isazi same here. But the N5X and N6P do have some issues with the battery and the bootloops.

Especially the 6P

[Dimitrios Kanellopoulos]

@isazi FYI I switched to oneplus 7

[isazi]

@Dimitrios-Kanellopoulos I switched to a Nokia 7 plus in the fall of 2018 and the battery is going strong. Used to have a oneplus 1 when they made their first product, but got a bit burned by the hardware bugs that plagued that release and haven’t had the courage to check other oneplus products after, although I am sure that after all these years they are much better now.

@Dimitrios-Kanellopoulos Great choice! Waiting for 1+ to arrive later in the week. You used to buy a sports watch. Now you buy a sports watch (well, a sporty smartwatch) and then you have to buy a phone to go with it
