Apple Watch Series 4 models contain batteries that are nearly 20% smaller

Apple Watch Series 4 models contain batteries that are nearly 20% smaller
Following in the footsteps of the new iPhone XS, which includes a smaller battery than last year's iPhone X, the new Apple Watch Series 4 models include significantly smaller power pack than their predecessors.

Published on Apple's website, the company's Product Information Sheet contains quite a bit of info regarding the batteries inside the new Apple Watch models. Specifically, it's revealed that the 44mm Series 4 device contains 1.12 watt-hours, while the smaller 40mm offering includes 0.86 watt-hours. For comparison, last year's 42mm and 38mm devices were equipped with 1.34 watt-hours and 1.07 watt-hours respectively. This translates into drops of 16.5% and 19.7%.

Despite the rather sizeable decreases in capacity, Apple claims that its new Apple Watch Series 4 duo are capable of achieving the same 18-hour battery life that was possible with previous-generation watches. Ultimately, though, Apple's official figures are yet to be put to the test, so there is no guarantee users will be able to reach the same levels in real-life scenarios. Fortunately, we will be putting the figures to the test in our upcoming review of the new Apple Watch Series 4, so be sure to stay tuned for it.

If I am correct, Apple made the watch slightly thinner this year. This is just horrible. Battery is more important than making the device slightly thinner than last year. Make it thin when new battery tech comes out. Battery is my only reason for not buying this years Watch as everything else looks great.

Again you Android buffaloes got things very wrong here. You get less battery capacity but same battery longevity out of the new Apple watch series 4. That means you pay more for better software + hardware optimization. Oh wait, out of all the people how will you stupid people know about that? It's called batter O P T I M I Z A T I O N. When this happens to your watch or phone it's overall functionality become smoother and way more fluid.

Eh, I like Apple products, I just wish that they don't make their products thinner and give better battery life. I know they optimize but the current battery time s**ks and claiming they have the same is not doing it any good.

pyath. why not, pay more get more? why not get more longevity? why apple has to decide if 18h (on the paper and not in real life) is enough for a user? are you guys that brainwashed that everything has to be fed to you and just take it without asking some basic questions? jeez you are pathetic.

The answer to your question is simple: Because Apple's competitors allow Apple to do so. The important question is: Why aren't Apple's competitors capable to create a product that is equally desired by consumers? If there were such competitors, Apple wouldn't dare to make such moves - Apple could not afford it.

Pay more get less... like the larger screen on the same footprint. Or more tech packed in the same footprint. Yet you dismiss all that because the battery is smaller. Android fan priorities.

I have this years watch and have been wearing it each day for 16 hours and still have 53% battery left. I use my watch quite a bit during the day and have it on LTE while I'm at the gym 1.5 hours. I don't notice any difference in battery life from my series 3. So far no regrets with the series 4.

Hey, leave your real life experience out of the comment section! This place is for android users to cry about something the never owned or will own.

Yup, And I agree that consumers who do not mind charging their phone everyday will be supper happy with the new Apple Watch. It is a great device in many ways. But, there are a lot of people who wish/want the battery to last longer as it is one less thing to charge daily.

Actually thinner is better for customer addiction purposes.

Agree! But more battery life is always better than same battery life- if you upgrade. Or not?

It's thinner this year but essentially the same thickness as the original Apple watch

I get about the same as my Series 3 got. I can go a day and a half easily, and I charge every night at bed time, so no worries. One thing I’ll say about the Galaxy Watch is, before the update that crippled the battery life, and led to me selling it, it got the best battery life I ever saw on a watch.

Having said that, at 4 days in, I already think it’s the best smart watch I’ve owned. On an overall basis, it’s unmatched. Battery, performance, features, looks, eco system, and strap comfort, it wins overall. 9.9 on the Darkk meter. Three day battery life, and the ability to erase individual texts from a persons folder, along with full workout logs viewable from the watch 9 (it’s all about fitness first with me), and it’d be a perfect 10. 3rd party faces would be great too, but the stock ones are very informative, so that’s a wash.

Apple Watch Series 4 is the best smart watch, all it needs is an always on mode and it’ll be near perfect. Oh and I’ve no complaints about battery life. Awesome Apple designed watch faces, excellent app support, Apple Music built in (on LTE models), and outstanding exercise tracking. Consumers have spoken, that’s why the Apple Watch is a perennial best seller.

I’m ok with battery life. I normally top it off close to bed time but take off charge before sleeping.

I let it charge overnight. Wake up to 100%, and I’m good. How’re you liking it?

But how can it monitor your sleep if you charge it every night?

13. darkkjedii

I’m not into sleep tracking dude, but obviously you wouldn’t charge overnight if you want sleep tracking. What I’d do is get home, charge it up, then put it on at bedtime. When I awake, check the metrics, slap it back on the charger to top it off, and be on my way. Bingo! Problem solved.

See how easy that was? I monitor my sleep by how many of my nighttime farts wake me up.

Battery on my series for 4 is the same as series 3 even if its smaller due to the fact that apple added faster S2. People never learn that hardware and software integration is the best in apple. It works seamlessly, efficiently and reliably. Can’t go out now without apple watch and AirPods now.

Well, with watches almost all OEMs do the same- hardware and software. Galaxy watches also have OS and hardware integration perfect(Tizen - the best). Right? So, what is your point?

Both galaxy and apple watches are exellent devices but i will stick to my amazfit bip ok its definately not in their league and has less featuresbut for what i use it is all i need plus a 30+ day battery life and low price was the deal breaker for me.

Guess that's how they made it thinner.
