Samsung Galaxy Watch 4 vs Galaxy Watch 5: Should you upgrade?

In 2021, Samsung introduced a Wear OS revolution when it launched the Galaxy Watch 4 and Watch 4 Classic. The duo shelved Tizen OS to strengthen Samsung’s partnership with Google on a unified software experience. In 2022, the Galaxy Watch 5 brought plenty of internal upgrades, yet the two lineups share many similarities. If you’re unsure whether you need to upgrade, let’s dig into our Samsung Galaxy Watch 4 vs Galaxy Watch 5 comparison.
Samsung Galaxy Watch 4 vs Galaxy Watch 5
Design

The Galaxy Watch 4 ushered in a slew of design changes to Samsung’s smartwatch formula. It simplified the button options and did away with the rotating bezel on the flagship option. If you wanted to keep that feature for another year, you had to pick up the Galaxy Watch 4 Classic instead. The Galaxy Watch 4 also offered smaller dials than its retro-inspired sibling, with 40mm and 44mm options. The Galaxy Watch 4 Classic is available in 42mm and 46mm configurations. Samsung’s standard Galaxy Watch 4 comes in colorful aluminum constructions, while the Classic sports either stainless steel or titanium.
For the base model Galaxy Watch 5, model size choices haven’t changed, which should make sizing an easier prospect. However, the displays themselves are slightly bigger, with the 40mm version growing from 1.19 to 1.2 inches and the 44mm moving from 1.36 to 1.4 inches.
The Galaxy Watch 5 offers the same sizes as its predecessor, but a physical bezel is no longer an option.
In the latest series, Samsung is rocking the boat in a slightly different direction. The Galaxy Watch 5 still offers two models, but neither features a physical rotating bezel. As mentioned, you can choose a standard Samsung Galaxy Watch 5 in 40mm or 44mm sizes, or step up to the Galaxy Watch 5 Pro, which comes exclusively in a 45mm design and a 1.4-inch display. The designs are very similar at a glance, with rounded displays, sizable bezels, and a pair of buttons on the right side.
However, the Galaxy Watch 5 picks up a durable Sapphire Crystal glass display, which Samsung claims is 60% stronger than the previous generation. It’s encased in Armor Aluminum, which matches its predecessor in toughness. The Galaxy Watch 5 Pro goes even further, pairing the Sapphire Crystal display with a premium titanium casing. Both watches have new color options as well, but we’ll get back to those below.
Whether you upgrade or stick with the previous Galaxy Watch 4 series, you can expect durability in spades. All four models offer IP68 ratings and are good for 5ATM — 50 meters — of pressure. You’ll get MIL-STD-810G ratings, too, in case you drop your watch or take a tumble.
Features

Samsung’s external changes may be minimal, but the internals are a different ballgame. We’ll return to the shared software in a moment, but let’s focus on the hardware first. Both series feature Samsung’s in-house Exynos W920 processor, as well as 1.5GB of RAM and 16GB of storage.
The Galaxy Watch 5 series gets a major boost in the battery department, with improvements across the board. The smallest 40mm model jumps to a 276mAh cell, while the 44mm version grows to 397mAh — both 13% larger than their fourth-generation counterparts. Samsung claims that the upgrade is good for 50 hours of juice on a single charge, which is 10 more hours than the previous version. If you need even longer battery life, the 45mm Galaxy Watch 5 Pro promises up to 80 hours with its 590mAh cell. We found these claims largely accurate during our review periods.
On top of improved battery sizes, the Galaxy Watch 5 series offers faster charging. It powers up to 45% charge in 30 minutes and can regain enough juice for eight hours of sleep tracking on an eight-minute charge. Now there’s not much excuse to go to bed with a dead watch.
A bigger battery and faster charging are the Galaxy Watch 5's biggest boost.
The Galaxy Watch 5 and 5 Pro also pick up new features thanks to additional and upgraded sensors. For starters, the Bioactive sensor is designed to make better contact with the wrist for more accurate readings and scan your skin temperature.
Other health tracking features include measuring your breathing, blood oxygen levels, snoring, sleep stages, and heart rate. Samsung can then blend these advanced metrics to develop a personalized sleep coaching plan. It should improve on the abilities of the Galaxy Watch 4 series, which itself was no slouch.
Samsung’s older model introduced improvements in measuring body composition, blood pressure, VO2 Max monitoring, and an ECG. These specs are successfully transferred to the newest models. Likewise, we found GPS and heart rate monitoring to be accurate on the series 5 devices as well.

While the Galaxy Watch 5 and Galaxy Watch 4 share the same Wear OS platform, Samsung’s newer watch introduces several features and watch faces to the mix. You can choose from eight options with 10 favorites. Smart Switch support also makes it easier to transition to a new watch.
The Galaxy Watch 5 and 5 Pro also support voice navigation via Google Maps. Samsung’s assistant is present as well, but the Galaxy Watch 4 series picked up Google Assistant support in May 2022, so that’s a wash. Wear OS offers an extensive app library and better compatibility with non-Samsung Android devices. However, the Galaxy Watch 4 didn’t provide iOS support, and there’s no change when it comes to the Galaxy Watch 5 either.
Additionally, Samsung’s wearables still lock certain features to Galaxy devices, including ECG and blood pressure monitoring, and default to Samsung Pay and Samsung Health out of the box.
Finally, the Samsung Galaxy Watch 5 Pro adds even more features to the mix. These include navigational tools like the ability to import maps and track routes — a few fitness wrinkles seemingly borrowed from Garmin.

The watches share many design elements and the same software platform, so your final decision might come down to price. The Galaxy Watch 5 series does come at a premium over its predecessor. However, it’s important to remember that it balances upgraded sensors and much-improved battery life. All the watches — save for the Galaxy Watch 5 Pro — are also cheaper than the original price of the Galaxy Watch 3.

Samsung Galaxy Watch 5 vs Galaxy Watch 4: Should you upgrade?

The leap from the 4 series to the 5 series might not be as great as from the Galaxy Watch 3, but it’s still enough to tempt a switch. For example, if you’re deep into fitness tracking and use your watch as a running companion, the improved sensors and larger batteries are worth the cost.
Furthermore, the Galaxy Watch 5 series will also get slightly longer software support, though the Galaxy Watch 4 still has plenty of updates in the queue. On the other hand, we may be right around the corner for an even newer Galaxy Watch 6 that could be worth the wait.
The Galaxy Watch 5 and 5 Pro are excellent wearables, but they might not be necessary upgrades for recent Galaxy Watch adopters.
If you picked up the Galaxy Watch 4 Classic for its rotating bezel, there’s less motivation for you to upgrade. You won’t find one on either Galaxy Watch 5 model. Luckily, the Galaxy Watch 4 Classic will remain in production for its die-hard fans. Plus, the Galaxy Watch 4 series will also receive extra sales and discounts as Samsung tries to clear stock. In other words, it may be the perfect time for a previous-generation purchase. Unfortunately, the lack of iOS support on either series means the Galaxy Watch remains off the table for iPhone users.
Of course, while Samsung’s latest will easily challenge the best smartwatches out there, maybe neither Galaxy Watch is right for you. The TicWatch 5 Pro is another fantastic Wear OS pick. There are plenty of options from Garmin to consider as well and they work equally with Android and iOS. Few wearables pair better with a Samsung Galaxy device, but the final say comes down to your set of needs.
