If you have been looking for a smartwatch with wicked battery life, then there’s a good chance that you have been searching high and low. Even when writing this article, we couldn’t find a good list of smartwatches ranked by battery life, which is strange because battery life is one of the most important features of any handheld device be it a smartwatch or smartphone.
Thankfully, we have drawn on our expertise in the smartwatch market to come up with a definitive list of the top 10 smartwatches for battery life in 2017, to aid your research and help you buy a smartwatch that isn’t going to conk out and be rendered useless after only the slightest use.
So without further ado, here’s the smartwatches with the best battery:
Battery life: Infinite - so long as you wear it!
The MATRIX PowerWatch is the first smartwatch in the world to be powered exclusively by body heat. Simply keep it on your wrist and it will display the time and date for you, and track your activity, without the need for battery changing or charging, ever. The only downside to that infinite battery life is that the MATRIX PowerWatch can’t send accept push notifications, so if you want smartphone alerts on your wrist, look elsewhere.
For those of you who are happy with a smartwatch that only lets you set alarms and tell the time and date, then a lack of push notifications is a small price to pay for never having to charge your smartwatch. The PowerWatch will even track your daily activity, and it displays your daily progress with a neat digital ring that runs around the edge of the display. You can pre-order yours today for around $99 from crowdfunding website Indiegogo.
Battery life: Up to two years.
The Kronaby smartwatch blends classic design with modern technology. It is available in four distinct styles: Carat, Apex, Nord and Sekel, and with a variety of bands which include leather and stainless steel variants. It is positioned as an upmarket smartwatch with a build quality rivalling that of watches costing ten times more. And, with a battery life of up to two years, it should be on your list if you want great smartwatch battery life.
Like all hybrid smartwatches (smartwatches with an analogue display, fitness-tracking sensors and Bluetooth for smartphone syncing), the Kronaby has a coin-cell battery that’s user-replaceable. The 2-year battery life betters all other hybrid smartwatches on the market that use a coin-cell battery as the power source. The Kronaby is fully-featured too, with push-notifications for your smartphone and functions accessed by physical buttons.
Armani Exchange hybrid smartwatch
Battery life: Around 6 months.
The Armani Exchange AX smartwatch was launched in January this year. It’s a hybrid smartwatch with a sporty design and a 6-month battery life, thanks to a coin-cell battery that’s user-replaceable. It has a unique feature where it automatically adjusts the time for you depending on where you are through GPS. It will even adjust for Daylight Saving Time for you (if applicable), and it connects to your smartphone through Bluetooth.
The AX comes as standard with a durable rubber strap. It’s available in Blue, Black or Orange, but all models have a black case and a mineral crystal covering the analogue watch face. Overall, this isn’t the best-looking hybrid smartwatch on the market but it’s certainly stylish and well-made. It will track your activity, such as your steps and sleep patterns, and the free application (available on Android and iPhone) is simple to use.
Mondaine Helvetica No.1 Smart
Battery life: Up to 2 years.
If you want a Swiss-made smartwatch with great battery life, then the Mondaine Helvetica No.1 Smart is hard to beat. With a 44mm case, this is a large, classically designed smartwatch that oozes quality. It has a 2-year (quoted) battery life which puts it on par with the Kronaby smartwatch listed above, and it too is available in multiple styles, including with a gold or PVD black-coated case, and with a classic stainless steel case.
This smartwatch is also compatible with iPhone and Android devices, and it comes as standard with an anti-reflective sapphire crystal display. This won’t get scratched no matter how rough you are with the Helvetica and although this smartwatch is designed to go under a suit cuff rather than in the water, it has a 30 / 100 / 3 (m/ft/atm) water-resistance rating, so you can go swimming or showering with it without any worries.
Battery life: Around 8 months.
The Nevo watch pitches itself as the “world’s first modern minimalist hybrid watch”, which isn’t exactly true, given the Withings Activité is minimalist. Look past that fact, however, and the Nevo watch is a decent smartwatch. It offers activity tracking, sleep tracking, phone notifications and a silent alarm (vibrate) function. And, crucially for a hybrid smartwatch, it has a decent battery life - it’ll last for 8 months thanks to a coin-cell battery.
On top of having a wide range of features, the Nevo watch looks great too. The case is made from high-quality 316L stainless steel and the glass is a sapphire crystal. Even the straps ooze quality, with your choice of a Fine Italian Leather or NATO strap. From the three available designs (New York, Shanghai, Paris), we particularly like the ‘New York’ model, which has a Black case and a Coffee-coloured leather strap.
Withings Activité, Activité Pop and Activité Steel
Battery life: Up to eight months.
With a battery life up of to eight months courtesy of a user-replaceable CR2025 watch battery, the Withings Activité, Activité Pop and Activité Steel are serious smartwatches for those of you who don’t like the idea of charging a smartwatch, ever. Withings is a very well-known and well-regarded consumer technology manufacturer and the Activité and Activité Pop follow on from the company’s other products in terms of design and build quality, which is to say the Activité range is impeccably well made and stylish.
The Activité is the range-topper. This is a Swiss-made smartwatch with a sapphire crystal protecting a clean white or black dial set into a polished stainless steel case. All Activité watches have an analogue time dial and a separate activity dial that gives you a visual indication of your daily step progress. All models will track your steps, calorie burn and your sleeping patterns. The Activité Pop is the cheapest model; this has a mineral crystal and an aluminium case and it isn’t Swiss-made, while the Activité Steel is the newest model with a mineral crystal and stainless steel case (it’s halfway between the Activité and Activité Pop).
All Activité models also offer a silent vibrate alarm and they automatically switch between walk, run and swim modes. They also automatically adjust to new time zones.
Battery life: Up to one month in timepiece mode.
If you want a smartwatch that’s both efficient and rugged, then little comes close to the new Casio WSD-F10. This smartwatch boasts a battery life of up to one month thanks to a very neat dual-screen setup. That’s right – there’s two screens! One is a 320 x 300 colour LCD (the main screen) while the other is a monochrome LCD screen. With the regular LCD screen always on you’ll get about a day’s battery life but switch to the monochrome one and you’ll get a lot more – up to a whole month according to Casio.
So with this watch, you can switch between screens to preserve battery life. To get the best battery life though, you can turn off all smartwatch functionality and enter ‘timepiece mode’. This displays only the time, making the WSD-F10 just a humble watch. In addition to that excellent battery life, the WSD-F10 is one of the most rugged smartwatches on the market with U.S military certification MIL-STD-810 – way beyond the IP67 rating most smartwatches have. The Casio WSD-F10 also looks fantastic and it’s available in a variety of different colours. We are particularly fond of the orange one. Overall, this is a fantastic smartwatch.
Battery life: Up to one month (in use, a bit less).
Smartwatch newcomer Vector may not be a brand on the tip of tech journalist’s tongues, but they do have two seriously good smartwatches on the market called the Vector Luna and Vector Meridian which both boast a battery life of up to a month. The Luna is a round smartwatch while the Meridian is a square smartwatch. Unlike the Withings, these watches have a monochrome LCD display. But curiously, they aren’t touchscreens.
Instead, the Vector Luna and Vector Meridian have three buttons on the side (a centre select button and two navigational buttons) and you navigate the watch’s features using these as opposed to touching your way around the operating system. Speaking of which, both models run Vector’s bespoke software made by their CTO Andrei Pitis. The software has been designed specifically for buttons and it’s compatible with iOS and Android tablets and smartphones. The watches themselves are very stylish and well-made and they offer all the usual fitness tracking capabilities that smartwatches do.
Pebble Time Steel
Battery life: Up to ten days.
With a battery life of up to ten days, you’d be forgiven for presuming that the Pebble Time Steel is no match for the Withings Activité. But it really is, because unlike the aforementioned the Pebble Time Steel has a touchscreen display and it offers ten days of battery life with heavy use. The reason it can do that, is because it has a unique colour e-paper (e-ink) display with LED backlighting and this sips power in comparison to AMOLED, OLED or LCD screens like those found on the Apple Watch or Moto 360.
The Time Steel is actually one of a trio of products from Pebble, which also include the Time Round and regular Time. The Pebble Steel is the best of the bunch though with a ten day battery life versus the seven day battery life of the Time and Round models. All models have a stainless steel bezel but the Time Steel also has a stainless steel case all round giving it a more premium feel as well. The Steel is compatible with Android and iOS devices and it runs Pebble’s own 3.0 operating system. As a result, it runs native apps downloadable from the Pebble app store but the number of quality apps has grown considerably this last year.
Sony SmartWatch 3 SWR50
Battery life: 2 days with normal use.
Although a 2 day battery life may sound paltry, when you consider the performance and features of the Sony SmartWatch 3, it really isn’t (this a smartwatch with a touchscreen, Bluetooth and Wi-Fi and all the usual sensors). The battery is a 420mAh unit (for comparison, the 42mm Moto 360 2nd gen has a 300mAh battery) and most people report just over 2 days of battery from this smartwatch with normal use. It will outlast an Apple Watch twice over, if they are both subjected to similar use. Now that’s impressive.
As far as features go, the SWR50 has a 1.6-inch, 320 x 320 LCD display powered by a quad-core ARM A7 processor and it is IP68 certified. This is beyond the IP67 certification a lot of smartwatches have and it means the SmartWatch 3 is protected against complete continuous submersion in water. So taking it into the bath is no problem at all. The Sony SmartWatch 3 is also one of the best fitness trackers around. Powered by Android Wear, it has a neat RunKeeper app and the GPS tracking is very good indeed. There’s 4GB of storage for your music and it also boasts NFC technology so sharing data is made very easy.
Sony hasn’t got the best rep when it comes to smartwatches, but the third iteration of their product is a great device overall. You should definitely consider it.
