vivoactive 4 (all versions) SW 5.10

Has anyone that is still experiencing battery drain considered trying to let the battery run to flat or until the device switches off. 

Perhaps there is a small chance the battery percentage calibration is completely wrong??? ¯\_(ツ)_/¯ 

As mentioned on here, before I went to bed last night, I switched to a stock watch face instead of my normal IQ Actiface. When I woke up, I had only drained 2% somehow instead of the typical 20%+

I'd suggest others try the same thing. I will be trying a few different IQ faces while sleeping to try and determine if it's all IQ faces or certain ones? (I only ever have 1 IQ face installed, no other faces)

Regarding the increased battery drain:

I usually use a stock Watchface or a Watchface called M2. Normal battery drain in smartwatch Mode is ~0,3-0,6% per hour. After the last update, like many others, I realized this numbers have doubled for me. Both with the stock and app watchfaces!

I have to report that after I've done a full delete and reset of my watch this problem still hasn't been resolved. Set up the watch yesterday night and within 8 hours it drained 15% battery again. 

Tbh this is really a big problem. I just bought the watch a few months because especially because it has great battery live. Now this advantage is almost completely gone...

I hope this get's resolved soon!

I've had my VA4 just 2 weeks 

It was on firmware 4.something, but within hours of setting it up updated to 5 1. The battery drain has always been low during the day and high overnight.

Reading this thread I tried downgrading to 5.0 only for 5.1 to get installed soon afterwards. So didn't have opportunity to check battery drain overnight on 5.0.

I use a built in  analogue watchface with always on second hand. Don't have any CIQ watchface or widgets installed. I was getting between 5 & 6 days battery life with no activities, but knew it could be better if the overnight battery drain could be reduced.

I decided to try the following. I actived SPo2 tracking overnight - the battery drain was similar to what I had been seeing with no SPO2 tracking. I then switched off SPO2 tracking and last night the overnight battery drain was significantly reduced, around 2% over 8 hours. Previously it had been around 8% over 8 hours.

During the day the battery drain is between 2 and 2.5  hrs per 1%.

It looks like the daily battery drain is going to near to 10%....giving a battery life of between 8 to 9 days (with no activities)

The battery drain for a GPS enabled activity, such as running, walking or cycling (the 3 activities I do) is approximately 5% per hour.

Whilst this has worked for my VA4, unfortunately it may not work for other VA4s. However, it is simple to try and may work!

Good luck

Please let others know your results

Huge battery consumption after the upgrade! On the vivoactive 4 now the battery lasts 2 days and before I was using it for 5 days without problems! I already tried to remove the GarminDevice.xml file and to bring to factory default thw watch with no benefits! This update is not working! Especially during the night, where is uses A LOT of battery. 

The same with my VA4!

Since 5.10 is the maximum 2 days, before at least 4 to 5 days.

Garmin, repair the firmware!

Yes, I am also concluding that the issue is with IQ faces. After downgrading I went back to 5.1 and went 2 days with a standard face and consumption was "normal" - meaning about the same as my 1 IQ face had when I was on 5.0. Then I switched to that IQ face and consumption in a 24 hour period is about 10% more. I feel like the varying degrees of "badness" people are experiencing is related to the particular IQ face they use and how much it is affected by the changes in 5.1.

To further update some of my testing, I've tried 2 different 3rd party IQ watch faces while sleeping, both had 20-30% battery drain while asleep. 

Last night I tried a Garmin IQ face (Classic Sport) and I only had a couple % battery drain. 

I will continue to test, but it is looking like 3rd party IQ watch faces might be the issue. Something Garmin changed in 5.1 is causing a bug with them. I will try a different 3rd party IQ tonight as well

there is no update as shown in Garmin Express.

Where did you purchase your watch. Some Asian Garmin products don't receive the same updates...
