TDK is a company that makes batteries for smartphones, including iPhones. They have created a new kind of battery that can make phones last longer and be thinner at the same time. This is very important because people want their phones to work well and look nice. TDK did this by using a special material called silicon in the batteries. This is similar to what some car companies do to make electric cars go further. TDK has also teamed up with Apple in India to make batteries locally for iPhones there, which is good for both companies and the environment. Read from source...

1. The title is misleading and sensationalized, implying that TDK's battery technology will transform smartphones, while in reality, it may just improve them slightly or provide a competitive edge.
2. The article claims that TDK is the "global leader" in smartphone battery supply, but does not provide any evidence or data to support this claim. This statement seems based on an assumption rather than factual information.
3. The article mentions TDK's collaboration with Apple in India, but does not explain how it relates to the battery technology innovation or its potential impact on smartphone market share or sales.
4. The article cites TDK CEO Noboru Saito as a source for the battery tech innovation, but does not provide any details about the nature of the innovation or how it differs from existing lithium-ion batteries with silicon electrodes. This makes the claim seem vague and unsubstantiated.
5. The article ends with an unrelated news headline that seems randomly inserted and has no connection to the main topic of TDK's battery technology. This suggests a lack of coherence and focus in the content.
