Apple Watch SE 3 review

I haven't worn an SE 3. This review comes from Apple's compare page, Expert Reviews' review from January 19, 2026, and the free part of Which?'s review from October 2025. The 7.3 is my opinion based on those.

The money first. Apple's price for the base model was $249Not verifiedNot verified when I checked on November 1, 2026. It wasn't on sale.

The SE 3 is the entry model in Apple's watch line-up. It sits below the Series 11 and the Ultra models. Which? says it came out in September 2025.

The battery is the dumb problem

Apple rates the SE 3 for up to 18 hours. The Series 11 gets 24 hours, also by Apple's numbers. That's 6 hours less on the cheaper watch.

Expert Reviews doesn't soften it. It calls the battery abysmal next to much of the non-Apple competition and tells you to charge daily. Eighteen hours means one full day, and it rules out wearing it to bed for sleep data unless you top it up somewhere in the evening.

Low Power Mode stretches the claim to 32 hours. I'd treat that as the setting for a trip where you forgot the charger, not something to live in.

What saves it is charging speed. Apple says 0 to 80% takes about 45 minutes, and 15 minutes gets you up to 8 hours of use. Expert Reviews gives the same figures. So the routine I'd use is 15 minutes on the charger while you shower. Annoying, but workable.

I haven't read a lab battery result from a named outlet, so the 18 hours above is Apple's figure, untested here.

What the rest gets you

Expert Reviews calls the SE 3 a hidden gem with 99% of the Series 11's features at nearly half the price. It gives no numerical score. Which?'s free teaser says it "looks to be a big upgrade" and calls it perhaps the smartest buy in the line-up. Its scores and its Best Buy status sit behind a sign-up, so I can't tell you more than that.

On paper, Apple lists:

• An always-on OLED rated up to 1000 nits, 368 by 448 pixels on the 44mm
• The S10 chip, 64-bit dual-core
• 32.9 g for the 44mm GPS model, 33.0 g with cellular
• Water resistance to 50 meters

An always-on screen on the cheapest Apple Watch is the part I'd care about most. You see the time without lifting your wrist.

If you run or hike with it

GPS is standard GPS. The Ultra models have dual-frequency GPS, which Apple reserves for the top of the range. For a park run that won't matter much. For long trail days, the 18-hour rating is the bigger problem anyway, before GPS accuracy even comes into it.

Who I'd buy it for

I'd buy it as a first Apple Watch, or to replace an older SE. You already charge your iPhone every night. Adding the watch to that habit costs you nothing.

I'd skip it if you want sleep tracking without thinking about the charger, or if you're coming from a Garmin or another watch that lasts days. Expert Reviews compares its battery with non-Apple rivals, and the SE 3 loses.

If the 6 extra hours of the Series 11 matter to you, check its price before deciding. Expert Reviews puts the SE 3 at nearly half of it, so you're paying a lot for those hours.
