Battery life

Former Member over 4 years ago

I've only had my Garmin forerunner 45 for about a week, and I have yet to get 24 hours out of the battery, after a 100% charge. Is there anything I could be doing wrong, or should I send it back for replacement?

I just started having this same issue a few days ago, having to charge it every night. Going to contact support.

I also have noticed this issue the past two days. I think it started since I last updated my app...I removed my watch from the charger at 8 this morning and it was at zero battery by 10. This happened yesterday too but I had assumed that I just didn't properly connect the watch to the charger two nights ago.

Garmin needs to update the app ASAP because my watch (which is less than 6 mo old!) is unusable in this state.

Hello, regarding the battery life loss you all are reporting, I have a few questions we are looking for the answer to.

Did you charge the device after receiving the low battery alert or did the unit auto power down due to low battery?
Were you in an activity?
Were there any recent settings changes to the watch?

Hello Brooks,

I'm having the same issues without using it on a daily basis. I even turn my watch off when I'm not wearing it.

I have every battery draining widget removed and all options turned off. I did one run(2.5hours) after fully charging it and my battery was back to 50%. I'm pretty sure there's a problem with activities(GPS?)

No settings were changed after the 4.20 update. The run was done with just pressing the right upper button 3 times(no workouts or paced run)

So I did another run of 1 hour and my battery went from 50% to 20%

I had a fully charged watch yesterday but after an 1 hour run my battery was back to 80%. Usually I take it of and turn it off but now I kept it on while sleeping and wore it today. After a full day my battery is still at 80%.

At 20% an hour it would mean my battery is dead after 5 hours of activities. This isn't normal, right?

Ps I'm using also using a Polar H10 during the runs.

Has anyone gotten an answer on this from support? I've had my Forerunner 45 for about 10 months and two days ago it started losing charge very quickly - usually a 100% charge would have lasted 2-3 days with regular runs without need to recharge - rarely fell below 60% - now it can be 100% charged, in the evening, I wear watch to bed and wake up with it giving low battery warning and showing 1% charge?! It did have a software upgrade recently (4 weeks ago?) that caused some problems with the link to my phone but that was sorted by resetting both.

Any ideas on the power problem now?

Nope no answer yet..

Since I noticed the battery issue i kept wearing it during night and daytime. It doesn't drain mine at all, only when I do activities. Maybe its a widget or setting you're using..

I wasn't even aware this topic was 10 months old, so it's obviously a problem before update 4.20.0 dropped. I'm considering to contact customer service but i don't want the hassle.

Thanks - it does seem to have sorted itself out now - I think it got pretty wet last week as I wore it whilst doing some landscaping in pretty heavy rain for a few hours and I think that may have caused some problems with it taking charge.

Seems back to normal now - will watch out for more problems though.
