The latest smartwatches are a true box of tricks on the wrist, providing access to phone and fitness tracker features, sports and weather updates, and even breathing exercises. All these qualities are supposed to make our lives easier, and we pay well for them. But a smartwatch does not help us when the battery is dead.
Enter the Samsung Galaxy Watch. It's an elegant, traditional looking wearable with an appealing mix of smart and fitness features, including the ability to receive and answer calls, emails and WhatsApp messages, make contactless payments, play music, and with Samsung's voice assistant Bixby to help. measure your heart rate and more.
There are two versions of the Galaxy Watch. The smaller one, which comes in rose gold or midnight black, has a 42mm screen and costs £ 279. The larger version, which comes in silver and has a 46mm screen, costs £ 299. A 4G model that allows you to make and receive calls without your smartphone is near, is due later this year.
It is crucial that the watches have a new battery type: 270mAh for the smaller clock and 472mAh for the larger clock. According to Samsung, a charge will hold the 42mm clock for four days, and the 46mm version will be seven

How long does the battery last for a smartwatch?
If you're looking for a smartwatch with a long battery life, you'll notice big differences between offers. This is partly due to the quality of the clock and partly because the manufacturer's information based on different (but often easy) use scenarios.
For example, Huawei has announced a watch that, according to one month, can manage with one battery charge ̵
Our tests are based on consistent, real-world scenarios. The longest battery life of a smartwatch we tested was three weeks – and the shortest was two days.
You can see the range of offered battery requirements from the selection of key models below.
Apple Watch Series 4 (£ 399)
The new Apple Watch Series 4 takes only 18 hours, according to Apple. Granted, it includes many features in a small device: GPS, a 30% larger screen, new animated clock faces, the ability to detect crashes and call emergency services on your behalf, three new FDA-approved heart monitors and a walkie talkie feature, to name just a few.
Still, it's disappointing that battery life is not longer – especially considering how much you pay for it. So it can not always be "an essential part of people's lives," as Apple described it at launch, as it becomes a stop-start experience. For example, it means you can not use it for sleep tracking if you need to recharge it every other day. The Series 4 does not have a native sleep tracking app, but you may have a third-party sleep tracking app installed.
But you do not care – it depends on why you buy it. One reason for buying an Apple Watch is undoubtedly to feel part of the Apple community and have a fashionable piece of technology on the wrist – so regular charging seems like a small sacrifice.

Garmin Vivoactive 3 (£ 210)
This GPS smartwatch has a lot to offer, including a 240×240 pixel touchscreen resolution, and durable gorilla -Glas, a wealth of sports, fitness and smart features and NFC to pay for payments with Garmin (if your bank is compatible). If you are serious about sports training, the ability to make VO2max measurements could use your heart rate to calculate your oxygen consumption and fitness. And it's compatible with both Android smartphones and iPhones.
Garmin claims that the battery life of Garmin Vivoactive 3 is seven days from a single charge. With GPS, this number drops dramatically to just 13 hours. Read our full Garmin Vivoactive 3 review to find out how much battery life we've had from this watch in our tests and whether we've been impressed by the other features.
Amazfit Bip (£ 60)
The Amazfit Bip is the first smartwatch you can buy in the UK from Chinese manufacturer Huami, who also manufactures Xiaomi devices. Huami claims that the Amazfit Bip will last up to 30 days in normal use and up to 45 days with minimal alerts. This is about 11 times as long as the Fitbit Versa (below).
Light and comfortable to wear, it looks like a member of the Apple family from a distance with its rectangular bezel. It does not have nearly as many smart features as an Apple Watch or other smartwatches, but you can still receive text, phone calls, emails, and social media alerts. It has a built-in GPS, a good selection of fitness sensors, a heart rate monitor, a barometer to measure altitude and various other good features.
At just £ 60, it could be a bargain. Whether this is the case in our Amazit Bip Review, we reveal.
Fitbit Versa (£ 178)
The Versa is Fitbit's second smartwatch; The first was the Ionic, which came on the market in 2017. Fitbit claims that the Versa (£ 178) will give you four days of battery life per charge. You only have to recharge it twice a week if that is.
The longer battery life means you can use it to measure your sleep pattern, unlike the Apple Watch (and unlike the Series 4, Versa has it a native app that can even monitor sleep apnea.
The longer battery life is partly due to the fact that there is no GPS – that is, you can not leave your cell phone behind when you're on the move and still expect that Your watch tracks it The Versa does not have as many smart features as the Series 4 or the Galaxy Watch Like the Amazfit Bip, you can receive text, phone calls, social media and calendar notifications, but do not answer.

We've talked about rechargeable battery smartwatches here as they did most commonly used. Hybrid or analog smartwatches have replaceable batteries that can last for up to two years.
Hybrid smartwatches have some smart and fitness features (such as when you receive text or email on your smartphone and sometimes follow basic steps)) but by no means as many as a real smartwatch. For more information about Hybrid Smartwatches, see our Hybrid Smartwatch Guide.
How to Extend Your Smartwatch's Battery Life
Here are a few more ways to make more valuable use of your battery:
- Reduce screen brightness. There are different opinions on whether you should keep the automatic brightness setting (if any) so that the screen can be automatically dimmed when it is not particularly bright. For some, this helps, while for others, the battery is consumed by constantly testing the environment to see if it needs to adjust itself. You may just have to play around with your watch and see what works best.
- Turn off the Always On screen. It's a bit annoying to tilt your wrist or tap on the screen to get the time, but if you can live with it, do it. Also set a short timeout.
- Disable smart notifications. Of course you only want to do that for a short time, otherwise it would be pointless to have a smartwatch!
- Set your watch to Airplane, Theater or Cinema mode, if any. This will let it sleep until you wake it up again.
Like What? Testing Smartwatches
For every smartwatch we test, we test battery life in a variety of everyday scenarios, both in our lab and in the outside world. We send 11 phone calls and 35 SMS to the guard and a number of social media notifications throughout the day.
We also check how long it takes for the battery to fully charge. Some go from 100 to 100% in less than an hour while others take up to three hours
And we check how much juice you get from a quick charge. That way, if you go out soon and your watch is dead, you know if it's worth opening it for a bit. Some even give you 43%. From others you will only reach 19%.
A smartwatch needs to reach 72% to be a Which? Best Buy. 10% of this is accounted for by the battery life.
Take a look at our Smartwatch Ratings to make sure you spend your money on a smartwatch with a decent battery life. Choose one that counts at least four out of five stars for the battery.
