Battery drain after update to 9.6

Hey folks,

I noticed an increase of >100% in battery usage after update to version 9.60. Before update, I was using about 0,25-0,3%/hour. After update it is at 0,6-0,7%/hour. My usage pattern did not change, am recording daily activities, mainly Strength training and a few runs, always about the same time in length.

Only thing I did not test yet is restoring factory settings to see if it goes away - obviously want to avoid losing all my stored data.

Does anybody else notice this?

Same here. Both with 9.10 and 9.60. A reboot (pressing and holding Light-Button for 15 seconds) fixed it for me.

Rebootet via shut-down over quick menue, did nothing for me. Will try the long-press method and report back.

Holding Light-Button for 15 seconds restart did fix it for me, too. For some reason shutdown over menue didn't.

I'm definitely seeing poorer battery on 9.6. I've restarted my watch, but with no improvement. Hopefully a format tweak will sort it. Battery life is a huge plus for me on the 935 - don't spoil it garmin!!

Have you reset as in post #5 above? Have you added anything that could be drawing current? Mine is 'clean' and I see no obvious difference.

0 gingerneil over 7 years ago

Philip - yes - rebooted as per #5; holding down the power button and doing a full reboot. Nothing else changed on the watch other than using Galileo in the GPS options. A 90 min run this morning resulted in avg of 8% an hour battery drain. This was about 5% before the 9.6 update.

I've had mine on since I took it off charge yesterday afternoon, ran for an hour this afternoon with GPS+Galileo and used ~5%. Not sure if that proves anything.

Seeing similar, can't quantify exactly battery life figures pre 9.6 but I know a charge was lasting a lot longer than it currently is. Just did a 30 min run with HRM-Tri / GPS & GLONASS, 6% decrease in battery, MyBattery's showing 0.64% per hr drain. Did a 'hold button for 15 seconds' reset the other day, has made no difference.

No major problem, be good to see it sorted though.
