Battery drain
- 
 Please keep in mind that battery needs a full circle 0-100 to calibrate. Thus you might see faster drops near 50-100 and slower at lower percentages.

 @Dimitrios-Kanellopoulos That’s a problem with the SV. It takes ages before it’s totally empty  I still haven’t used the charger since the watch is delivered. And it will take a couple of weeks I guess. 
- 
 @surfboomerang I only used it because I needed more maps  
- 
 @surfboomerang You can leave the watch with an activity started and wait 2 days to drain the battery!  
- 
 during my last activities battery drain was ~5% in one hour. I lost 50% of battery in 10 hours bike ride - custom sport mode, weather + climb sport apps and navigation where I had more than half of the time only black tiles…

 @Tieutieu yes, it is off. in standby battery is OK

 So this happened today… Yesterday I went to bed and had still more than 30% of battery left. I however woke up with 16% battery left, not sure what happened overnight, but I have also had only 51 minutes of sleep recorded. 16% is still enough, so I went out for a bike ride. When I started the activity, the battery prediction showed only 2 hours of activity left - that was strange. I changed the Battery mode from Performance to Endurance, which showed 3 hours - so I went for the bike ride. After 30 minutes the watch turned the power saving mode on, and shortly after that turned itself off. So yesterday at 22:30 it was 30%+ and today around noon 0%. Standby is OFF. Brightness and Rise to wake on Low. Any idea? 
- 
 @tomasbartko First, did you check Standby backlight? Second, has the battery cycled from 100% to 0% to calibrate? The percent battery may not be correct, see posts on this. 
- 
 @Brad_Olwin I have Standby turned off, but I didn’t go through the first cycle. I have read comments about the first cycle, but have never experienced this with previous watches (also from other brands). Is this “Vertical specific”? 
- 
 @dombo using two S+ apps results in twice the battery consumption 
- 
 @isazi even if an app just displays the notes or some very simple stuff? 
- 
 @Łukasz-Szmigiel seems so to me, I think it needs further optimization 
- 
 Hi, I want to cycle the battery from 100% to 0%. 
 Currently it is 20%, is it necessary to completely drain the battery or do I have to charge it before?Thank you

 Currently it is 20%, is it necessary to completely drain the battery or do I have to charge it before?Thank you Interested with the answer too ! Currently 4%…it’s hard to get it to 0% !!

 @Tieutieu 
 I’ve done a dummy activity to drain completely to 0%.
 it’s not too hard when gnss is active, it actually goes very fast… at least in my case 
- 
 @Tieutieu I did battery draining with max light (always on) and maps open inside my home. 
- 
 may i know under what condition need to do battery calibration? is it every new watch recommended to do battery calibration?  
- 
 @babychai 
 basically every electronic gadget need a battery calibration once 
- 
 @sartoric haha alright, thanks. trying to drain the battery to 0% now. seem like the battery is very tough. using hiking mode with turn on the backlight and battery very stubborn to drop
