A handful of Garmin Forerunner 945 users have complained about battery drain. The issue appears to have arisen as a result of the most recent software update.
Forerunner 945 owners have flocked to social media and Garmin forums to express their dissatisfaction with software update 6.2. On February 18th, the firmware was made available. It was a significant upgrade, with a broad list of new features. This link will take you to the complete changelog.
While some of the new features are beneficial, there is one unintended consequence of installing the software. Users have reported that their Garmins only survive 3–4 days in smartwatch mode, as opposed to the prior 7–10 days. The watch uses roughly 1-2 percent of the battery every hour.
A few ideas to consider
When a Facebook user called customer service, she was advised that there had been a number of similar inquiries. He mailed his 945 to Garmin, and three days later, he received a whole new one. He upgraded it to version 6.2, only to discover that the problem was still present!
Those who are complaining should try a hard reset, according to Garmin support. However, reviews indicate that this is ineffective in resolving the issue. At the very least, it’s worth a shot.
When one user deleted the pulse-ox gadget, he had some success. So it’s possible that this is worth a shot.
Typical techniques for extending the life of a Garmin watch’s battery
The typical remedies for extending the battery life of Garmin devices may help, but they will not solve the problem. We’ve included a list of them here for completeness’ sake.
One approach to improving the life of your watch’s battery is to turn off the illumination. Even the brightness of the backlight influences how quickly the battery drains. As a result, setting the backlight to 100% is probably not a smart idea! The timeout setting can also be changed. This regulates how long the backlight will be turned off. Alternatively, you can use the manual backlight setting. It saves a lot of battery life.
Most people are aware that when turned on, built-in GPS consumes a significant amount of energy. Make sure to use it just to track outdoor activities.
Another option is to utilize the regular GPS tracking mode in this case. Because the device is connected to many satellites, using additional modes such as GLONASS will be less energy efficient. This can be done under your watch’s GPS settings.
Vibration alerts use a lot of battery power. Battery life will suffer if you have a lot of alerts, each of which causes a vibration. To gain extra juice, turn off the vibration.
Select only the most important notifications and turn off the rest. This can be done by navigating to settings > notifications center in the smartphone app.
The Bluetooth connection consumes power as well. How much it costs is determined by the number of alerts you receive and how frequently you sync. There’s really not much you can do about this besides turn off notifications and avoid syncing too frequently.
Should you make a change?
If you haven’t upgraded your Forerunner 945 yet, you may want to wait until a patch is released. Hopefully, Garmin will resolve the issue quickly and things will return to normal. Other devices in the company’s lineup have already experienced this issue, which was resolved with a software update.
If you still want to take a chance, you can get the update via Garmin Express via the smartphone app. Before you take any action, you should look into the Garmin forum that discusses the issue.
