Slim but at What Cost? Weighing the Trade-offs of the Samsung Galaxy S25 Edge and Apple iPhone 17 Air
In the race for thinner, sleeker smartphones, brands like Samsung and Apple are pushing the boundaries of industrial design. The upcoming Samsung Galaxy S25 Edge and iPhone 17 Air are prime examples—both boast remarkably slim profiles that cater to modern aesthetics and pocketability. But is the sleek form factor worth the trade-offs?
The Samsung Galaxy S25 Edge may have gotten its price leaked by accident.
Galaxy S25 Edge and iPhone 17 Air — The Pursuit of Thin-ness
Both devices are rumored to be among the thinnest flagship phones ever released. At about 5.5 to 5.9 mm in thickness, these devices redefine portability. However, thinner smartphones inevitably force manufacturers to make compromises—most notably in battery capacity, camera hardware, and thermal management.
- Samsung Galaxy S25 Edge: Reportedly focuses on a curved-edge design with a refined build and a modest battery capacity of around 3,900 mAh—down from the Plus model’s 4,900 mAh and Ultra’s 5,000 mAh.
- iPhone 17 Air: Apple is said to be prioritizing thinness above all else, potentially removing physical buttons and scaling down the battery size in favor of lighter materials and tighter internals.
Slim Design vs. Battery Life — A Constant Tug-of-War
One of the biggest trade-offs in going slimmer is battery life. Thinner batteries naturally have less capacity, which impacts screen-on time and overall device endurance. While software optimization can help, power users may feel the squeeze.
- Is all-day battery life still realistic? If you’re streaming video, gaming, or multitasking, even the most efficient chips may not offset the limitations of a smaller battery.
- Fast charging helps, but it’s not a solution. Even with 90W or higher fast charging, needing to recharge mid-day isn’t ideal for most users.
- A protective case would add more bulk anyway. If a slim device is more fragile and requires a case, then that somewhat beats the point of it slimness. Even if it isn’t more fragile but you’re still going to use a case, then what’s the point?
Are We Losing Functionality in the Name of Form?
Another concern is feature removal. In pursuit of thinness, manufacturers often ditch features like:
- Headphone jacks
- Expandable storage
- Either telephoto or ultrawide cameras
- Larger cooling systems (leading to potential thermal throttling)
For instance, the Galaxy S25 Edge is rumored to skip the telephoto lens found in all of its siblings. The iPhone 17 Air may also scale back on camera hardware, opting for a simpler lens array, possibly even a single main camera.
What Do Users Really Want — Thin or Capable?
Consumer trends show mixed signals. While some buyers love the ultra-thin aesthetic and feel of premium materials, others value practical features like battery life and camera performance more. If you carry your phone in tight pockets or prefer a feather-light device, the S25 Edge or iPhone 17 Air may appeal to you. If you’re a power user who values performance, photography, and battery life on the other hand, the trade-offs may not be worth it.
The Samsung Galaxy S25 Edge and iPhone 17 Air showcase what’s possible when design is king—but not without cost. While they are marvels of engineering, users must ask: Is slim really worth it?
If your lifestyle aligns with sleek design and moderate phone use, these devices may be perfect for you. But if longevity, advanced features, and thermal performance matter more, you might be better off with their slightly bulkier counterparts.
We’re saying this because we’ve seen trends in the industry over the years where the removal of certain features simply do not make sense, and it appears that we’re going to see that happen again. It could be the removal of the USB port, volume buttons, or even specific cameras. We get the need to be innovative, but not at the cost of the consumer’s convenience.
