Apple Watch Series 11 vs Samsung Galaxy Watch 8: Worth $80 More?

Both the Apple Watch Series 11 and the Samsung Galaxy Watch 8 landed in 2025 as flagship smartwatches, but they are not really fighting for the same buyer. Your phone picks the winner for most people — and after that, battery life and GPS accuracy do the rest of the talking.

Key Differences

• Battery life: Galaxy Watch 8 lasts 40 hours; Apple Watch Series 11 lasts 24 hours. That is a full extra day between charges.
• GPS: Galaxy Watch 8 uses multi-band GPS. Apple Watch Series 11 is single-band. In cities and under tree cover, multi-band wins.
• Phone lock-in: Apple Watch only pairs with iPhone. Galaxy Watch 8 is Android-only (and works best with Samsung phones).
• Price: Galaxy Watch 8 starts at $349.99. Apple Watch Series 11 starts at $429. An $80 gap out of the box.
• Body composition: Galaxy Watch 8 has BIA for body fat and muscle mass readings. Series 11 does not.
• Depth and dive data: Apple Watch Series 11 has a depth gauge and water temperature sensor. Galaxy Watch 8 does not.
• Screen size: Series 11 has a larger 1.96-inch display. Galaxy Watch 8 runs a smaller 1.34-inch screen on the 40mm case.

Deep Dive Comparison

Design & Comfort

The Galaxy Watch 8 is the lighter, smaller watch — 30 grams in a 40mm armor aluminum case. The Apple Watch Series 11 comes in at 37.8 grams with a 46mm aluminum case. If you have a smaller wrist or sleep with your watch on, the Samsung is the more comfortable pick. If you want a bigger, more readable face during workouts, Apple’s 1.96-inch LTPO3 OLED is noticeably larger than Samsung’s 1.34-inch Super AMOLED. Both are rated for 50 meters / 5 ATM of water resistance, so pool swims are fine on either.

Battery Life

This is where the Galaxy Watch 8 pulls ahead and does not let go. Samsung rates it at 40 hours in smartwatch mode (about 1.7 days) and 14 hours with GPS running. Apple’s Series 11 is 24 hours in smartwatch mode (1 day) and only 7 hours on GPS. If you want to track a long hike, a marathon, or simply skip a nightly charge, Samsung’s numbers are not close — they are in a different class.

Health & Fitness Features

Both watches carry an electrical heart sensor (ECG), optical heart rate, SpO2, and a temperature sensor. Both have an accelerometer, gyroscope, and ambient light sensor. The split shows up in the extras:

• Apple Watch Series 11 adds a depth gauge, water temperature sensor, high-g accelerometer, compass, and altimeter. Better if you’re snorkeling or shallow diving.
• Galaxy Watch 8 adds Samsung’s BioActive sensor with BIA for body composition (body fat %, muscle mass, body water). Better if you are tracking recomposition or training load.

For GPS accuracy during runs and rides, multi-band on the Galaxy Watch 8 is the practical advantage. Single-band GPS on the Series 11 is still solid on open roads, but it drifts more around tall buildings.

Smart Features

Both watches have NFC payments, a mic and speaker for calls, Bluetooth 5.3, and Wi-Fi. The Apple Watch Series 11 adds LTE standard, Wi-Fi 4 (802.11n), and UWB Gen 2 for precise iPhone handoffs and Find My. The Galaxy Watch 8 has dual-band Wi-Fi (2.4 and 5 GHz), with LTE only as an optional SKU. Apple also brings 64GB of on-watch storage versus Samsung’s 32GB — handy if you load a lot of offline music or podcasts. The apps story is Apple’s strongest point: watchOS simply has more polished third-party apps than Wear OS.

Price & Value

Launch prices set the tone: Galaxy Watch 8 at $349.99 versus Apple Watch Series 11 at $429. Street prices swing both cheaper during sales, but the Samsung is consistently the less expensive watch, and it is also the one with the longer battery and better GPS hardware. That is a rare combo — usually you pay for the better specs. Apple’s price premium is really paying for the iOS ecosystem and the app library.

The Verdict

The Samsung Galaxy Watch 8 is the better piece of hardware. Longer battery, multi-band GPS, lighter case, BIA body composition, and an $80 lower price. If you’re on Android — especially on a Samsung phone — buy the Galaxy Watch 8 and don’t look back.

Buy the Apple Watch Series 11 if you own an iPhone. Full stop. It is the only answer. You get the biggest screen in this matchup, a depth gauge for shallow water, UWB for iPhone handoffs, and watchOS’s much deeper app library. You also accept nightly charging and weaker GPS in cities.

Buy the Samsung Galaxy Watch 8 if you use Android, want real two-day battery life, care about GPS accuracy on trails or in downtowns, or want body composition tracking without buying a separate scale. It is the smarter spend.
