Anyone experiencing high battery drain should start with a hard reset (holding the power button for up to 15 seconds). If this does not resolve the issue, more information will likely be needed from you…

hello Former Member,

what i can tell for sure is that currently (with only spo2 activated during night and daily steps tracking) the battery life of the 945 is way worse compared to the 935. with 1-2 workouts…

Can't we have statement from Garmin if they have noted that there is an issue with battery drain and they plan to solve it?

Hello,

Do you have SpO2 activate during sleep ?

I noticed SpO2 mesures during all the period of sleep (defined in user parameters).

Before FW 2.80, SpO2 mesures only during 4 hours in the night.

It even worse for me.

I charged my watch in the night. I put in on this morning and here 5 hours later my 945 is telling me that I only have 10% left!!!

you are right, it looks like the SpO2 measurement changed really from only 4 hours in the night to the whole sleep period!

is that deliberately so intentional by Garmin? (sorry, my english is not the best!)

Did you try hard reset after FW upgrade?

0 Rasmustj over 5 years ago in reply to Kub3k

A hard reset did the trick

Did you delete everything or just hold light button for 15 seconds?

My Watchface Blink shows (if activated) the number of minutes in high power mode per day. If this value is not below or around 100 minutes your watch doesn't fall asleep.

this battery drain is more or less clear, there was a change by Garmin to use Pulse OX over a longer period greater then 4 hours during sleep!

all other battery drains issues are different!

0 f|33tStA over 5 years ago in reply to f|33tStA

could it be that not the longer Pulse OX measurment is the Problem, instead the 24 hours altidude measurment?

it don't stop:
