It's widely known that Samsung and Apple are gearing up to unveil new, sleek devices next year. The Galaxy S25 Slim and the rumored iPhone 17 Air are both in the works, but recent information suggests they might not be as thin as fans hope.
Challenges in Design
According to leaker Jukanlosreve, both companies are facing challenges in achieving the desired slimness for their upcoming models. For Samsung, the Galaxy S25 Slim is said to be released in limited quantities. They are prioritizing battery performance over thickness, which means the phone might not be as thin as anticipated. Additionally, it appears Samsung will not be using silicon-carbon battery technology for the S25 series, thus missing out on the density benefits that other devices like the Honor Magic 6 Pro and Vivo X200 have.
Apple's Battery Choice
On the Apple side, the report indicates that plans for a new type of battery have been abandoned for various technical reasons. Therefore, the iPhone 17 Air—regardless of its final name—will come equipped with standard lithium-ion batteries, which will likely result in a thickness exceeding 6 mm.
The Slimness Debate
While a thickness of around 6 mm is a significant reduction from the current slimmest iPhone, which is the 7.8 mm-thick iPhone 16, one has to wonder if that’s truly "slim." It's worth noting that Gionee previously released the Elife S5.1 in 2014, measuring just 5.2 mm thick. However, at that time, it housed a rather small 2050 mAh battery.
