Battery drain after update 2.44.46 (2025 Q3) on Vertical Watch

@slash1111 i have 15% drop over the weekend where i used another device for tracking my exercises …

After monitoring battery consumption for 11 days, I can say that either my perception (of increased consumption) was mistaken, or that the soft reset and unpairing and re-pairing of my external HR monitor solved any potential problem.
Battery consumption remains excellent. -

Battery consumption remains excellent.After un restart battery consumption is good. But for me, probably after one or several workouts (with arm sensor) something trigs a high battery consumption with more than 10% a day. I have not identified what is exactly this trigger

Hello,
I have also noticed an overall decrease in the battery life of my Vertical since a few updates (more or less since June 2025). Battery consumption used to be around 10/12% per day without GPS activity (7% during the day and 4/5% at night). However, for the past few days, I have been manually closing the Suunto app in the background and… magic… battery consumption has been halved. Now I’m between 5/7% per day with 1 hour of GPS per day in performance mode, 24/7 HR tracking and sleep tracking. This still doesn’t match Suunto’s estimates (i.e. 30 days of battery life), but it significantly improves my watch’s battery life.
So there may be an additional bug, but remembering to close the app manually is a good idea.
I have a Suunto Vertical Solar Titanium made in China and an iPhone 14 Pro running iOS 26.

@GuillaumeA What do you mean by disabling an app in the background? I also have an iPhone, but I wouldn’t know how to do that apart from the usual swipe up

@fedequei Sorry, English isn’t my native language: I may not have been clear.
That’s exactly right, it’s the swipe up from the control bar at the bottom of the home screen. You’ll see that your watch no longer syncs automatically, so the weather widget may no longer be up to date, and activities no longer sync automatically at the end of the activity, but doing it once a day is enough.
My routine has become: I get up in the morning, synchronise the watch for the weather widget and sleep tracking, then manually close the app. Then, if I’ve been running or doing an activity, I synchronise again.
Basically, I’ve gone from multiple automatic synchronisations per day to two manual synchronisations. This obviously has an impact on the battery.
