So far 14.20 has been positive for me with the battery. Doing spot checks shows it back to .3 percent per hour and staying consistent.
Still 6% in 6 hours.
I can't believe it takes Garmin months to figure out the problem.
I even got a replacement a few days ago, when contacting the support regarding the problem.
With that performance…
Update: 100% at 8.00 now 95% at 16.00
Wiyjout any activity or GPS, only HR.
Not OK at all. Incredible.
Exactly the same as with everything turned on.
I tried every combination. Even hard reset and skipped coupling to the phone.
Always the same result, 1.3/h.
After 50 hours and a 10k trail run (Galileo, GPS), Bluetooth notifications, WiFi, stock watch face w/second hand, battery down to 82%. The run chewed up 7%, so net 5.5%/24 hours on Fenix 5X. Did notice GPS took a tad longer to acquire, but this was first 'run' since the upgrade.Tracking accuracy reasonably accurate. Using Elevation Correction, elevation was off by 20% (237m vs 177m). This is consistent with v14.10 and v13.30 (GSP 2.50 issue). I haven't tested GPS 2.51 beta.
Going on 5.5 days now since last recharge.Battery level now 56%. Deducting out 2 x 8.5km runs (7% each run), my 5x consuming 5.5% per day with Bluetooth and WiFi turned on, second hand showing on stock watch face. Tracking against route is very good, but elevation is still 30% off. Running up then back down 4.25km route, watch shows elevation 168m. After enabling elevation correction, shows 235m. I'm still using GPS 2.50 (GPS mode only). GPS acquired quickly on 2nd run after updating to 14.20.
