vivoactive 4/4s SW 4.00 is now live

Today I tried to turn off Bluetooth for sleep, result is 1.1% per hour over night. No bluetooth, no WiFi networks, no PulseOX

It really looks we are facing some SW issue which has avoided to you for some reason. I will probably need to do all factory reset and clean install again and try to find the starting point because I didn't notice it first time. Battery consumption was 0.3% and than suddenly 1.2% nothing much between for me

I agree about battery usage "degrading" over time. I did a cleanup where I reset, charged from 0% to try to recalibrate the battery, removed all the stuff from the watch face, etc., and suddenly I was on like a ten-day per charge thing... for about four days. Then it jumped back to its "new normal" of about 1.2% per hour. At one point, while doing NOTHING AT ALL, it said it was using 1200.00% per hour. Um... yeah.  Interestingly, I removed HR and all the frequently updated things (even steps) from the watch face but realized today it didn't make any difference. Still getting 3.6 days per charge with or without those things. I guess I will put them back on?

I have talked to Garmin and confirmed that the settings that I have are currently what they state as should be giving 7 days battery life (I have the 4S) - smartwatch, plus activity tracking. They want me to send in the watch to have it checked and acknowledged that it should be getting more than 3 days per charge. 

What I DO wish they would add in their marketing is that ANY exercise you record will take a huge bite off the battery, so if you exercise even 30 minutes a day, your battery life will probably go down to like 2-3 days (or at least that is what my watch is doing). To me that is ENORMOUS. I also purchased this watch over two other choices BECAUSE of the advertised battery life of 7 days. I didn't realize at all that was NOT including recording exercise. And I don't even use GPS or music. I can't imagine getting much more than a day of battery life if I were using this watch for daily running.

That said, I have plenty of days where I do not exercise, and the battery life is equally awful. 1-2% per hour, as bad as 4% per hour, is not acceptable when looking at how little of the watch functions I actually use.  I had another activity smartwatch for about ten days (one on each arm to compare) and honestly wish I could have kept the other one because the screen and battery life were amazing. It just didn't have a few of the functions that I really need and therefore chose to stick with this one. I am still sort of regretting it and wondering if I would really miss those functions...

regarding this battery issue: is it normal, that my HR sensors is running constatnly? I mean it NEVER stops blinking. Even when I put my watch out of my wrist it is blinking for ever

So, to be clear, I have tested bluetooth by leaving it on for a full day a couple of times and it hasn't seemed to have an effect on battery life (I have done a lot of battery life tests).  I am just guessing that maybe if I left bluetooth on all the time, it would eventually cause a battery drain glitch, but I have no proof of that (and obviously it shouldn't). 

The only things I can point to between when I had crummy battery life (4-5 days) and when I had very good battery life (10 - 14 days) is: 1.) I switched the watch face and what was displayed, 2.) I charged the watch for an hour beyond 100%, and 3.) I switched the music source to "Phone" to grey out the music player (note it doesn't grey out if Bluetooth is on, but I always leave it in "Phone"). 

Other than that, I guess I am just fortunate so far.

What about your HR senzor, is it blinking constantly? 

No es normal. Asegúrate de que lo tengas actualizado a la versión reciente 4.00. 

Si este no fuera el problema, deberías de reiniciarlo

If you mean was the HR sensor blinking brightly when I took the watch off and not shutting off, I did have that bug, but version 4.0 cleared that up.  I have not had that problem for a while now.  It never really affected battery life for me because I wear my watch almost all the time.  My battery life issues cleared up well before that bug was fixed. 

If you are asking do I track HR 24/7, yes I do.

Ok so this bug is still there for me and I am also on fw 4.00. My HR sensor is blinking even when charging which is ridiculous

Second point I also tracking HR 24/7 but I expected that sensor will take some samples during time (for example every minute) but mine is blinking every single second during all day, but from what I read I guess this is normal

Anyway, it's staring to by hopeless, 2.2% per hour over last night 

10-14 days? Are you sure you have Vivoactive 4? Garmin claims that economical usage (no activities, no GPS, no music, rare notifications, rare usage, stock Watchface, no pulseOX etc.) provides up to 8 days of battery life and I can confirm that with my device.

Currently on a 3rd party WF with rare refresh rate, 2x40-60min GPS activity (bike)/day (usually 1 bike activity takes 4-6%), quite a lot notifications, constant connection to phone, no pulseOX, HR ON, it provides up to 4 days on a battery life and basing on other users experience it's normal.

Currently I have -28%/1.2 days = -1.0%/h, 3 days left since last charge (2h11 of 3 bike activities).

I can confirm that sometimes power usage increases in time (to e.g. 1.0%/h without GPS activity) but soft reset usually corrects that.
