I have Fenix 5s Plus which is just over 2 years old. The battery charge life has dropped significantly over the past month and currently will no longer hold a charge. After the leaving the watch plugged in to the charger for an extended period and the watch showing 100% charge as soon as I remove the charge cable the watch turns off completly. supert3d1975 over 4 years ago. Perhaps a repetitive question? Looking for confirmation. My Fenix 5 has stopped charging. I'm suspecting the cable, connectors look fine on the watch; however on the cable I've noticed there a 4 small pins; one of them has either got stuck/recessed or broken off? Are there 3 or 4 pins on those cables? 5X Plus, 8.01 beta, almost 6 days since the last full charge. 24/7 OHR and 10+ hours of outdoor running, I'm at 30% right now. I have backlight turned off (for both running and daily life) and rarely use other functions though. For reference, I completed an 8-hour mountain bike ride with GPS running and my Fenix 5S plus lasted for 7:48 of it. Go off the beaten path with this Garmin fenix 5S Plus smart watch.

The Fenix 5+ has an ongoing bug where after a firmware upgrade you'll occasionally see a significant increase in battery usage. Rebooting it fixes the problem. No idea if the 5 has the same problem, but it's an easy thing to test. cygon4. Excessive battery consumption. Enry421 over 4 years ago. Hi. I have just purchased the 5 plus series and I would like to know if the consumption that in my opinion seems excessive, could be due to fw 7.60 or with normal use, I could have a loss of 10% / 15% a day, with a use of gps that does not exceed 2 hours.
