Garmin Forerunner 25 Review

Design

Garmin came up with this smartwatch in 2015, one year after its predecessor Forerunner 15, with a lot of new and improved features. Firstly, Garmin made sure that this watch is wearable by everyone, so it was released in two packages; large and small. Everything is the same in these two packages except few parameters.

The small ones have a dimension of 35 x 44 x 13.9mm and are available in black/violet and white/pink. On the other hand, the same smartwatch in the large design has dimensions of 40 x 47 x 13.9mm, and available in black/blue and black/red. Other than this slight change in dimensions, display size, weight, and battery life, everything in them is the same.

Display

This smartwatch has a square-shaped design and by the looks and appearance, it gives the same vibes as Forerunner 15, but the features are quite different than that watch.

The small design comes with a display of 0.73 x o.73 inches (18.5 x 18.5mm), while the large one has the display comprising 0.91 x 0-91 inches (23 x 23mm). The display type is sunlight-visible and transflective memory-in-pixels (MIP). The glass is made up of acrylic material, whereas the watch has 128 x 128 pixels.

The display is not really out of the world, but it still does it its job effectively. To make sure you can see the display in direct sunlight, it has an LED backlight. The brightness of this LED is pre-set and you cannot do anything about it. It also has 4 physical buttons, which are assigned a specific job, and they’ll do your required work quite easily.

The one I’m reviewing here is the larger one, which weighs approximately 39g which makes it a lightweight package per se, along with this, the straps are made up of silicone material and looks good on one’s wrist.

GPS tracking

Having a GPS tracker in your smartwatch is important, especially when you are a fitness enthusiast and you want your outdoor activities to be tracked precisely. For that, this forerunner comes with built-in GPS tracking, which keeps a tab on your location and activities pretty easily. The GPS let alone can track your pace, distance, calories, lap time, lap distance, average pace, etc.

Activity tracking

Like most smartwatches, it offers the all-day activity tracking too, where it keeps tracks of your number of burnt calories, step count and distance traveled. You can set your records and see if your daily activities are going well with the defined barrier.

Inactivity reminder

It’s just the sedentary reminder, where if you have been sitting in a still position for a long time, the inactivity bar will start filling and after an hour, it will give you the alert to move a little bit.

Heart rate monitoring

As this forerunner 25, was launched at the time when this feature wasn’t this popular, but nowadays it is considered important, as you can have the insights about your heart rate on your wrist.

This particular smartwatch doesn’t have an optical heart rate sensor, which means there’s no wrist-based heart rate tracking, which is a bummer for sure. Although it still has all the functionality related to HR tracking, that requires a chest strap.

Once, you’ve set up the accessory with this watch, it will keep an eye on your heart rate very precisely. You can use this feature to compare your steady heart rate with the pumped up one, after a heavy workout to see the actual difference. Along with this, it also alerts the user if the heart rate is considerably high or very low, and it will give you a beep alert according to the situation.

Running modes

There are no specific sport modes in this smartwatch, which gives the user the opportunity of tracking their favorite games, but that’s understandable because this smartwatch is quite old. That being said, it still can track your indoor and outdoor running with the help of GPS and accelerometer.

If you are just going for a run without any specific parameter, you can just choose the “basic run” option, and it will keep track of your running session by giving all the details about the distance, time and calories burnt during the very process.

There’s another feature of lap tracking, where it will continuously track down your running session and will give you alert after completing a lap of defined kilometers or miles.

An auto-pause function is there to make sure the readings are as accurate as possible, as a lot of times, you take a break while running and if the timer doesn’t stop, it will disturb the whole scenario.

If your running session is the mixture of walking and running, you can activate the relevant tracking, and it will take care of the rest by giving you the stats at the end.

Along with these running modes, it also offers indoor running, where you can run on the treadmill and it will be tracked simultaneously. But this indoor tracking is not really up to the mark per se, and Garmin does need to improve this in upcoming smartwatches, which they certainly have.

Live tracking and activity profiles

Live tracking is the feature, where your family members can see your activity stats of burnt calories, distance traveled and the step count. This feature is helpful when you are buying and want to keep it as an activity tracker for kid, where you’ll have the check and balance on their activities by motivating them too.

On the other hand, activity profiles help to create a proper portfolio of your activities and they just won’t disappear out in the open. You will know how much work has to be done to beat your personal best.

Virtual pacer

It works like a running buddy of yours and keeps on updating whether you’re going with the desired pace or not. You can set your required target which you have to achieve in the defined time, and when you start running, you’ll exactly know are you going to achieve this task by going on this pace or not.

Smart notification

After connecting to the Bluetooth of the required smartphone, it will be able to receive all the notifications of it without any trouble. Although it’s not a standalone smartwatch, since the two-way communication is not there, but being a fitness smartwatch, it still can help you if you’re busy in a workout and don’t want distractions by picking up your phone. Just have a glance at it, and you’ll know who’s calling or what the message.

Water-resistance

This smartwatch comes with 5ATM water-resistance, which means it withstands the water-intrusion up to 50m under the water. This makes it not only a water-proof smartwatch, but there’s also a basic rest timer feature to track your swimming session. So, jump in the pool, go for light snorkeling, diving and take a bath while having it on, and it will not get damaged by that.

Battery life

The large and small packaging of this smartwatch has also different battery life as well. The one in large size can last up to 10 weeks in a simple watch option and approximately 10 hours in GPS mode. On the other hand, the small package can last up to 8 weeks in the simple watch, while 8 hours in GPS mode.

Although it’s a known fact, that the GPS connectivity drains battery the most, so if it can last for 10 hours in constant GPS mode, it’s fine. It’s not the best, but it still will do the work for you.

Although the heart rate tracking ability of this smartwatch is not something to be highlighted about, because of the accuracy issues.

Forerunner 25 vs Forerunner 35 (Comparison)

Design and display

Forerunner 35 has a comparatively good overall look as compared to forerunner 25, and that is because of its shape and size. Although the size doesn’t matter here, because they have almost the same size, that being said, forerunner 35 still wins the battle here.

Heart rate monitoring

Forerunner 25 does offer the heart rate tracking, but for that, you’ll be needing the chest strap as an accessory, which can be a liability for many people. As you cannot wear the chest strap all the time, so whenever you want to measure your heart rate, you’ll be needing that.

On the other hand, forerunner 35 comes with wrist-based heart rate tracking, which uses the optical heart rate sensor for the tracking of heart rate. Now, this is where the two smartwatches part their ways, as forerunner 25 doesn’t have this feature of wrist-based heart rate tracking.

For a fitness enthusiastic person or in general, if you want to keep track of your heart rate all the time, forerunner 35 has a clear edge here.

Sleep monitoring

Forerunner 25 doesn’t have a sleep monitoring feature, while forerunner 35 does have it. You can track your sleeping schedule with it quite easily and can get detailed insights about light, deep and REM cycles during the night.

Cycling feature

Forerunner 35 tracks your cycling session with the help of sensors and accessories, but forerunner 25 cannot do that. So, if you are into cycling and want your sessions tracked, you should choose forerunner 35 over 25.

Battery life

Forerunner 25 comes in two versions; small and large. The large one can last for 10 weeks in smartwatch mode and 10 hours in GPS mode, while the smaller version can last for 8 weeks in smartwatch mode and 8 hours in GPS mode.
As compared to these two, forerunner 35 can last for 9 days in watch mode and 13 hours in GPS mode. However, the forerunner 35 has an edge of a couple of hours in GPS mode, but still, it cannot beat the enormous days of battery life in watch mode, which forerunner 25 has. So, keeping this factor in the account, forerunner 25 wins the battle here.

Pricing

Garmin forerunner 35 will cost you 30 more bucks as compared to forerunner 25, with all the perks and features. If pricing is not an issue, you should go for forerunner 35, but if you’re low on budget, forerunner 25 should be a priority.

 

Editor’s Verdict

I personally like Forerunner 35 more than forerunner 25, because of many things. Firstly, I love its design, overall look, and appearance over anything. That being said, I’m not against the design and look of forerunner 25, but I feel like it’s quite outdated.

Secondly, its features which include wrist-based heart rate tracking, sleep monitoring, and sport modes are top-notch. As the people nowadays are moving towards smart life and they want to keep track of their every physical activity, I’d prefer forerunner 35 over 25 any day.

However, as far as battery life is concerned, forerunner 25 does beat its successor over here with a large margin in watch mode, so if your usage is not GPS related at all, you should go for forerunner 25, otherwise, Forerunner 35 should be your ultimate pick.
