Qualcomm Announced A New Watch SoC 4100 (CPU)

Does anyone know if the Fenix uses Qualcomm chips or something else? Moving from a 28nm process to 12nm is promising 85% faster and 25% less power. That would make for a sweet Fenix 7.

Garmin uses NXP processors for its Fenix line watches, just as displayed here: http://www.f-blog.info/garmin-fenix-6x-pro-disassembly-or-teardown-whatever-you-say/

Well he said 3+ years, I don't think he meant to imply that the battery WILL need to be replaced after exactly 3 years. In most cases the battery should last at least 5 years, especially on a 6X where…

What CPU do they use?

I think it's an inhouse ARM design. I know the Qualcomm ones, even with 12nm, don't appear to be that good with energy considering most Wear watch's have appaling battery life

Competiton is following and when the battery life will be at least 4-5 days or even 7 daysand that can be achived in 2-3 years, will be Apple, Samsung and others good choices too. And decisive will be a little things like medical functions (next big thing), properly functional WHR all the times and others.

Qualcomm SoCs are used mostly by watches with Wear OS by Google.

I believe the screens are the main contributor to Wear watches battery life woes.

No. Since the fenix has a MIP display (memory in pixels). It only uses electricity to change one pixel. Pixels that remain the same do not consume electricity.

NXP Kinetis MK28FN2M0ACAU15, seems to be the main control center of the device. Garmin used this processor in the Fenix 5 plus series too. Older Fenix 5X had Kinetis K61 version. Kinetis K28F is 150MHz ARM Cortex M4 CPU with single precision FPU. It has 2 MB flash memory and 1 MB SRAM. It has 8 KB I/D and 8 KB system caches.

Battery show promise for replacement with some saudering for those who plan to keep for 3+ yrs

Interesting that the GPS antenna seems to be around/inside the front bezel - I wonder if the bezel itself is (or is part of) the antenna.
