Hello!

This is iPhone Repair Worker Shinjuku Main Store.

Our store is located within walking distance of Shinjuku Station East Exit, and is patronized daily by many customers, including those who live in the neighboring Shin-Okubo area and those who enjoy Korean cuisine and shopping.

Today, we'll delve into a common problem that every iPhone user faces: battery issues.

■ Those symptoms might indicate the end of your battery life. Are you experiencing problems like: "It was 100% in the morning, but by lunchtime it's less than half," "It was at 30% just a moment ago, but then it suddenly shut off," or "The whole system is laggy and slow"?

The lithium-ion batteries used in iPhones are consumables that gradually degrade with repeated charging. As degradation progresses, not only does the operating time shorten, but gas can be generated inside the battery, causing it to swell and push up the screen.

Even more serious is the possibility that unstable voltage will prevent the CPU from receiving sufficient power, leading to system crashes or the "Apple logo loop" where the system repeatedly restarts. This is especially true during colder months, and for those who frequently play demanding games or watch videos, as the battery is under greater strain. If the maximum capacity shown in the "Battery Health" section of the Settings app is around 80%, it's a sign that the battery needs replacing.

■ Just a short walk from Shin-Okubo! Speedy repairs in as little as 30 minutes. If you find yourself inconveniently needing a mobile battery while strolling around Shin-Okubo enjoying street food and taking photos, please stop by our store.

Our battery replacement service does not touch any of your important data; only the battery part is replaced with a new one. The work can be done in as little as 30 minutes . You can enjoy lunch or shopping while your battery life is restored to stress-free condition. The work time may vary depending on the model and how busy the store is, so please feel free to contact us for details.

Don't neglect your iPhone just because "it's still working." We recommend early maintenance for a smoother iPhone experience. Our experienced staff will carefully support your valuable device.
