SE3 Battery Life performs better than expected
From the article: “In testing, the SE 3 lasted nearly two full days on a single charge, which is well beyond Apple’s 18-hour battery life estimate for the watch. It powered 46 hours with typical use in the real world before it ran out of juice and needed to be plugged in. During that time, I had the always-on display enabled, used the GPS for two different workouts, sent texts, downloaded apps, and regularly checked my activity and sleep stats. Surprisingly, it did better than the Series 11, which lasted 43 hours on a charge in my testing.” More on reddit.com

Apple Watch SE3 battery life lasts 8 hours
Exercise drains the battery fast too. Gym class, recess etc.. His school has reception, maybe not the best, but pretty sure Apple Watch can utilize LTE. Are you sure he’s not texting or making calls? Playing music, etc..? More on reddit.com

How’s everyone’s experience with the Apple Watch SE 3 so far?
Been using my 44mm SE3 Cellular for a few days. Haven’t used cellular yet as my MVNO doesn’t have it yet. I use my S3 at night so haven’t completely tested the battery but when I’m done with it before bed it has a solid 45% left. I’ve been on the yearly upgrade train since S0, the best thing about SE3 is haven’t noticed any worse function than previous non-SE watches. Overall I’m happy so far, my plan going forward is being on the SE upgrade train. More on reddit.com

Apple Watch SE 3 review: Brilliance on a budget
Having an always-on screen is a big upgrade for the Apple Watch SE. It’s in the nature of the device, as a fitness wearable, that it often gets used in odd or awkward positions where you can’t easily rotate a wrist or spare a hand to touch the screen, and being able to check key data regardless of this is helpful to a degree you probably won’t appreciate until you try it. The only possible downside is its impact on battery life... Apple makes the best smartwatches on the market, but what if your budget doesn't stretch to the $399 Series 11? (Let alone the $799 Ultra 3.) You consider the Apple

Apple Watch SE 3 review: Still the best choice for most
Following real-world testing, this is our thorough review of the Apple Watch SE 3—including analysis of battery life, design, and features. It's been three long years since we last saw the Apple Watch SE, a smartwatch that has quietly become one of Apple's most important products across its entire spectrum. The SE line has always had to perform a tricky balancing act: it needs to be compelling enough to be the default Apple Watch for the masses, yet not so good that it cannibalizes its more expensive sibling—in this case, the Series 11. With the Apple Watch SE 3, the company has just abo

November 4, 2025 - The only meaningful feature you miss out on is the ability to take ECGs, but if you know you don’t need it then that’s no loss. The 1.5-day battery life of the 40mm isn’t too bad but the larger 44mm should last a little longer.

The SE 3 also misses out on the modest bumps to battery capacity and battery life in the Series 11. You’re giving up this handful of features in exchange for $150 off the price. For the average person, that tradeoff is absolutely worth it. When I tested the second-gen SE in 2022, it felt like a first-time buyer’s Apple Watch...
