Samsung Galaxy Watch Four Overview: Finest Smartwatch for Android

Samsung’s Galaxy Watch Four is an enormous deal, and never just for Samsung. It marks a reinvention of the corporate’s smartwatch line, but in addition the introduction of latest software program co-engineered with Google – making this additionally the debut of the overhauled Put on OS 3.

The excellent news is that Samsung has principally nailed the expertise. From a {hardware} perspective the Galaxy Watch Four is difficult to fault, whereas the brand new software program makes this mainly one of the best smartwatch you should purchase that doesn’t have an Apple brand on it – for now at the very least.

The one actual draw back is that Samsung is busy erecting a walled backyard to rival its Californian rival, and in consequence the Galaxy Watch Four is at its greatest when paired with a Samsung cellphone. Different Android homeowners will at the very least nonetheless discover a lot to love, even when a pair options are lacking, however iPhone customers are left within the chilly – this gained’t work in any respect.

Design and construct

Minimalist aesthetic
Obtainable in two sizes
IP68 & 5ATM water-resistance
Appropriate with customary watch straps

The Galaxy Watch Four boasts a slick, sparse design that appears good, however clearly isn’t meant to attract an excessive amount of consideration to itself.

It’s obtainable in two sizes – 40mm and 44mm – and a spread of colors: black and silver can be found for both measurement, whereas pink gold is reserved for the smaller mannequin and darkish inexperienced for the bigger model.

I’ve been testing the bigger mannequin, and it does really feel a bit of chunky. The 40mm mannequin might fare higher, however I doubt it – they’re the identical thickness at 9.8mm, so if something the smaller variant might really feel proportionately heftier.

In any case, the round watch physique itself is encased in what Samsung calls ‘Armor Aluminium’ – the identical metallic it makes use of for the frames of the brand new Galaxy Z Fold Three and Z Flip Three telephones. The default strap is a rubberised quantity, however in fact Samsung sells numerous choices, and both measurement of Watch Four will also be fitted with lavatory customary 20mm watch straps – although they gained’t sit fairly as flush in opposition to the physique as Samsung’s official curved straps.

On the watch itself you’ll solely discover two buttons alongside the right-hand aspect, with all different controls restricted to the contact display screen – take a look at the costlier Watch Four Traditional in order for you a bodily rotating bezel and extra conventional aesthetic.

After all, the Watch Four can be waterproof, with an IP68 score for mud and water safety, together with a 5ATM score – which means it’s good to face up to strain as deep as 50m. Throw in a Gorilla Glass DX+ coating on the show and an MIL-STD-810G toughness score and it’s best to be capable of belief this to carry as much as most tough therapy.

The lengthy and in need of is that the Galaxy Watch Four is enticing however restrained. If you need a watch that both stands out or emulates basic watch designs, this gained’t be it, however when you want your smartwatch to get out of the way in which and allow you to give attention to what it really does, this could actually enchantment.

Show and audio

Vibrant, vibrant AMOLED show
All the time-on show choices
Built-in mic and speaker

With such a minimalist design elsewhere, additional prominence is given to the Watch 4’s show.

Samsung has opted to make use of an AMOLED panel right here, and it’s vibrant and vibrant even in direct daylight, with actually punchy colors that benefit from array of watch faces included – with over 20 put in out of the field, most pretty customisable, and lots extra obtainable to obtain.

The smaller 40mm mannequin features a 1.2in, 396×396 panel, with the bigger 44mm mannequin leaping to 1.4in, 450×450. These are the very same shows discovered within the two sizes of the Watch Four Traditional, for what it’s price.

There may be nonetheless a reasonably thick black bezel across the edges of the show – one benefit of the Traditional, the place that is principally blocked by the bodily bezel – and I’d wish to see Samsung shrink this area subsequent time round, although it isn’t actually too bothersome.

One perk of choosing OLED tech is that it helps an always-on show possibility, which can maintain the time and another info on-screen 24/7 – although at a reasonably critical hit to battery life, so I’d solely advocate it when you’re constant about charging every day.

Thankfully, the raise-to-wake and tap-to-wake choices each work effectively, so I by no means felt like I used to be lacking an excessive amount of by switching off the AOD. Further display screen settings like enhanced contact sensitivity for gloved use, or a water lock to disable contact enter whereas swimming and showering, present Samsung has thought rigorously concerning the different complications a touch-sensitive smartwatch can introduce.

As for audio, an built-in microphone and speaker imply that you may take calls instantly on the watch or use it for digital assistant management. Bluetooth audio can be obtainable to patch by way of on to headphones.

Software program and options

‘Put on OS Powered by Samsung’
Intensive app and watch face ecosystem
Bixby built-in – Google Assistant added afterward 24 Could 2022

The Galaxy Watch Four is – type of – the debut of Google’s third technology of Put on OS.

Put on OS Three is a collaboration between Google and Samsung, which had beforehand developed its personal TizenOS to make use of on its smartwatches. Strictly talking, Put on OS Three doesn’t debut till 2022, and as a substitute this watch formally runs ‘Put on OS powered by Samsung’. Virtually talking, that is clearly a primary glimpse at Google’s overhaul, albeit with Samsung’s spin on high.

That implies that you’ll get Samsung’s personal new One UI Watch interface, which implies that navigating the Galaxy Watch Four feels nearer to the corporate’s Galaxy telephones than something from Google, whereas precedence is given to the likes of Samsung Pay and Bixby over the likes of Google Pay and Google Assistant – Google’s cost system is supported, however not by way of {hardware} shortcut.

Out of the field the Watch Four features a fairly customary array of smartwatch options: a number of health and well being monitoring (extra on that later), plus calendar, contacts, alarms, timers, climate, and a voice recorder.

Notifications are absolutely supported too, together with a welcome array of choices to answer to incoming messages, from just a few brief automated responses to a squiggly, gesture-based keyboard to kind out longer replies.

Since launch, Samsung has added gesture controls to simply accept/decline calls, cancel alarms, or open a set app. Google Assistant assist has additionally made its strategy to the Watch Four line, 9 months after launch. These usually are not solely welcome additions however a great indicator that Samsung intends to maintain the Watch Four up to date with software program enhancements.

If you wish to add a bit of additional, the largest software program enchancment right here is the choice to put in new watch apps from the Google Play Retailer. That opens up a number of apps, from watch face collections to YouTube Music and Spotify, utilities like Google Hold or AccuWeather, and third-party health and well being instruments from the likes of Adidas and Calm.

Along with apps, you’re extra prone to navigate the watch by way of the Tiles, that are laid out to the proper of the house display screen. These are primarily quick-access widgets for every app, and are the simplest method to make use of the cellphone’s health options and extra. They’re easy to tweak, choose, and re-order, so it’s fast to customize the Watch Four to greatest go well with how you employ it.

On the Watch Four Traditional, you’d use the rotating bezel to rapidly scroll by way of these Tiles, whereas right here you are able to do the identical factor by spinning your fingertip spherical the sting of show. It takes a bit of getting used to, however haptic suggestions as you spin makes this a surprisingly satisfying strategy to navigate the OS.

As talked about above, the Watch Four will work with any Android cellphone, although will miss out on a few particular health options. On iOS it’s a unique story although, because the Watch Four gained’t work in any respect – so iPhone homeowners who don’t need an Apple Watch should look elsewhere.

Health and monitoring

80+ health actions
Coronary heart charge, SpO2, sleep & stress monitoring
New physique composition sensor

The Watch Four options health and well being monitoring that would solely be described as ‘complete’.

Due to an array of sensors you possibly can maintain monitor of not solely your coronary heart charge, but in addition blood oxygen ranges, irregular heartbeats, sleep high quality, stress, and one main new one: physique composition.

Very like many good scales, the Galaxy Watch Four makes use of bioelectrical impedance to evaluate the proportion of fats, muscle, and water that makes up your physique. Testing takes 30 seconds or so, and includes touching the buttons with two of your fingers for the length.

The outcomes weren’t completely in line with my Withings Physique Cardio, which I believe is the extra correct of the 2. However for a fast guideline that is useful, and it’s a genuinely distinctive characteristic evaluate to different smartwatches. It also needs to be welcome to anybody who desires to trace their physique composition with out obsessing over their precise weight, which is difficult to keep away from when utilizing a scale.

Different monitoring is straightforward and dependable, with coronary heart charge, stress, and sleep all capable of run mechanically, and the rest handbook. Sleep monitoring is very spectacular, with outcomes intently matching these from the under-mattress Withings Sleep Analyzer.

Knowledge is shared with the non-compulsory Samsung Well being app in your cellphone. The one exceptions are the ECG and blood strain readings, which for some cause are as a substitute shared with the distinct Samsung Well being Monitor app – which is just obtainable on Samsung telephones. With no Samsung cellphone with the app put in you possibly can’t take an ECG or blood strain studying in any respect, so when you’re on another Android system then bear that in thoughts.

Exterior of these well being options, there’s in fact step and health monitoring. 13 trackable exercises are put in by default, however Samsung Well being options greater than 80 so that you can select from in case your favorite isn’t included out of the field.

Computerized exercise monitoring is there to assist to, and has impressed me with its reliability, kicking in even on comparatively brief walks – and together with within the monitoring the stats from the primary jiffy or so earlier than it really prompts the exercise mode.

Specs and efficiency

New Exynos W920 chipset
Clean efficiency
16GB storage

Specs aren’t the very first thing folks take into consideration with a smartwatch, however they’re price contemplating.

Samsung has upgraded the chip contained in the Galaxy Watch 4, and the brand new Exynos W920 is notable as a result of it strikes to a smaller and extra environment friendly 5nm course of. In idea which means elevated energy, but in addition improved energy effectivity.

Setting battery life apart for the second, there’s clearly loads of energy right here. The Galaxy Watch Four is persistently easy and fluid to make use of, and throughout just a few weeks with the watch I by no means felt it lag, stutter, or wrestle with something I requested it to do.

The chipset is paired with 1.5GB of RAM and an improved 16GB storage – which doesn’t sound like a lot, however for a watch ought to be a lot by way of each put in apps and downloaded music for offline playback.

Bluetooth 5.Zero is supported, together with Wi-Fi (although not Wi-Fi 6), together with NFC for funds. LTE can be obtainable, although you may have the selection of paying additional for it, with Bluetooth+Wi-Fi solely fashions additionally obtainable.

Battery and charging

As much as two-day battery
Wi-fi charging – however not Qi

Samsung quotes ‘as much as 40 hours’ of battery for the Watch 4, and that’s about proper – although there’s an enormous vary of variability relying on how you employ the watch.

On the default settings, together with sleep monitoring, I discovered the Watch Four would final me nearly two days, so I didn’t must stress about charging it every single day. After all, battery will degrade over time, however it appears doubtless that this may all the time be capable of safely final at the very least the 24 hours for a full day together with sleep monitoring.

Activating the always-on show will drain that battery considerably, and primarily turns it right into a single-day system. Components like how frequent you set the center charge monitoring, how a lot you employ the Watch Four for train monitoring, and the way a lot you employ it for music playback or replying to messages, will in fact have an effect on battery life too.

I’ve been testing the bigger 44mm mannequin, which unsurprisingly comes with a bigger battery too. The 40mm model might not final fairly as lengthy – however then it does have a smaller show to compensate for the smaller battery, so in actuality I’d anticipate all of it to stability out.

It takes roughly an hour and a half to achieve a full cost on Samsung’s equipped puck charger, although you’ll get sufficient juice to final the day from simply half an hour or so. That’s not dangerous, however I’d nonetheless wish to see quicker speeds – on a busy day it’s possible you’ll wrestle to seek out the time to depart your watch charging whenever you don’t want it, except you’re prepared to forgo sleep monitoring.

It additionally helps wi-fi charging, and might be topped up by way of the reverse wi-fi charging on sure Samsung Galaxy telephones – although that is achingly gradual. It technically doesn’t use the Qi customary, so gained’t work with customary wi-fi chargers. Some folks report higher luck with this, however I attempted on two charging pads with no success.

Worth and availability

The Galaxy Watch Four is accessible worldwide now, and between the 2 sizes and LTE choices is basically obtainable in 4 variations:

40mm Bluetooth: £249/€269/$249

The Galaxy Watch Four continues Samsung’s spectacular smartwatch monitor file, however the partnership with Google appears to have elevated each events.

At the least till Put on OS Three launches in full in 2022, this iteration might be one of the best smartwatch software program outdoors of an Apple Watch, and the chipset enhancements and physique composition monitoring be sure that the {hardware} is specced to match.

It’s a disgrace that a few the monitoring metrics are restricted to Samsung cellphone homeowners, which is perhaps sufficient to make different Android customers hesitant – and iPhone homeowners can’t use this in any respect.
