Garmin Forerunner 55 : Battery Life Is Very Good
As someone who has owned many Garmin devices, I can attest to their exceptional battery life. When it comes to brands that specialize in multi-sport, it’s essential to have a battery that can be relied upon for extended periods.
The Forerunner is a smartwatch that has an impressive battery life. According to the manufacturer’s claims, it can last up to 2 weeks. In my experience, this claim is solid. When I don’t use GPS tracking, I can get close to 16 days out of it. However, since I use GPS tracking almost every day, I’ve found that it lasts for at least 10 days.
In this article, I am going to go over the battery life of the Garmin Forerunner 55 based on my typical usage. Additionally, I will provide information on the GPS battery consumption rate per hour, which is something that is very useful to know, as GPS tracking is a major battery drainer.
As a final result I have given the Forerunner 55 a perfect score when it comes to battery life based on my typical usage. I will go over each category in detail, so here is a summary of my findings.
Category | Rating |
Speciality | Multi Sport |
Battery Economy Without GPS Tracking | 5/5 |
GPS Battery Consumption Rate Per Hour | 5/5 |
Overall battery Economy | 5/5 |
Final Score | 15/15 |
What is My Typical Usage
When I ever test watches for battery life, I always follow the same set of rules just to maintain some kind of consistency. At least that way each device I test is treated equally. I dont normally use the Bluetooth calling feature so that’s why I have left it out, and I dont use it during testing. However it would have made a big difference if I did.
I will be following through with this list, and treat GPS tracking as a completely different entity and you will see why at the end of the article
- All day heart rate tracking including sleep tracking
- AOD : 20-25 screen activations
- 50 minutes workout tracking
- 20 messages
- 1 hour of GPS tracking
Battery Economy Without GPS Tracking : 5/5
The battery economy is quite favorable based on my usage, and I sometimes neglect to charge the device because it can last for several days without needing to be recharged. Based on my typical usage without GPS tracking, I was able to achieve almost 16 days of battery life if I allowed it to run out, but I always end my test once 90% of the battery life is depleted.
It’s a practice that I use with all watches that I test because it allows me to compare how they perform against other smart watch brands. Here is the final results of my testing.
Feature | Result |
Battery Consumption Rate Without GPS Tracking (Per day) | 4% |
No of days | 16 |
So Why Did I Give Forerunner 55, 5 Stars for Battery Economy
I have tested so many smart watch’s and I have developed a rating table. In my opinion it’s the best way to provide an unbiased view on a device. At least that way you can see how a device would rank against other smart watch brands.
Please note that this rating table is based off my typical usage. The 11% gap from a 5 star device versus a 1 star device is absolutely significant. I always end a test once 90% of battery is consumed so if we were to use this number in terms of number days then the 5 star device would put out 15 days versus a 1 star device would put out 5 days. Most devices that I test are around 3 or a 4 star economy.
No Of Stars | Economy |
5 Stars | Up to 6% |
4 Stars | 7% – 10% |
3 Stars | 11% – 13% |
2 Stars | 14% – 16% |
1 Star | 17% and over |
How Does The Forerunner 55 Rank in The Market
Now please note that this ranking table is based off my typical usage. What you see before you is the economy rates for the most recent smart watches that I have tested.
