Ultra-slim smartphones were supposed to be a big thing this year, or so smartphone makers like Apple and Samsung thought. An iPhone Air and a Galaxy S25 Edge later, it doesn’t look like the trend will stick. Thin phones that only bank on their slimmness to attract buyers may very well be on their way out. Reports are already swirling about sluggish sales for the iPhone Air and Samsung Galaxy S25 Edge, and strong whispers suggest both lines may never see successors, and you know what, that’s probably okay.
We recently conducted a survey on Android Authority asking readers to choose between having a huge battery on their phones or a thin design, and the results are extremely clear: battery life matters to users far more than thinness ever will.
Huge battery or thin phone: Which would you buy? Our survey gathered roughly 8,500 votes, and a staggering 88.4% of the respondents said they would rather have a phone with a huge battery, sacrificing an ultra-thin design in favor of more screen time. Only 7.7% said they would choose a thin design, while 3.9% said neither feature is especially important to them. The verdict is clear and echoes a long-running trend we’ve noticed year after year — when given the choice, consumers always pick battery longevity over aesthetics.

The poor sales performance of the iPhone Air and Galaxy S25 Edge underscores this consumer sentiment. Apple’s troubles even deepened recently when a key member of the iPhone Air design team departed the company, casting even more doubt on the future of the product line. Meanwhile, strong rumors and information gathered from industry insiders suggest Samsung has canceled the Edge series altogether as its ultra-thin design language failed to move units.

Comments received on our survey show that thinness no longer has the same wow factor it once did. Meanwhile, battery expectations have skyrocketed, especially as silicon-carbon infused batteries become increasingly common, enabling many new smartphones like the OnePlus 15 to deliver two full days of solid use without dramatically increasing thickness.
