iPhone 17 Air just tipped for killer upgrade that could blow away Galaxy S25 Edge

The iPhone 17 Air just tipped for a killer upgrade that could blow away the Galaxy S25 Edge. Apple’s upcoming iPhone 17 Air may come with a big battery improvement, even though it’s expected to be thinner than previous models. This could give it a major edge over rivals like the Samsung Galaxy S25 Edge, which has had to reduce battery size to stay slim.

The secret behind this upgrade is new silicon battery technology, which can hold about 15% more energy in the same space as current batteries. Apple’s battery supplier, TDK, has sped up production and now plans to start shipping these improved batteries by the end of June — earlier than expected.

According to TDK’s CEO, some phone makers could start using this new battery one generation early, which may include Apple. That means the iPhone 17 Air, likely launching in September, could be the first Apple phone to feature this new tech — not a future model as previously rumored.

Other phone makers in China are already using silicon batteries in their top devices, since they last longer. Thanks to silicon’s ability to store more lithium ions than older graphite batteries, phones can stay ultra-thin without sacrificing battery life — something Apple is aiming to achieve with the iPhone 17 Air.
