Your Battery Life Just Got Better

When to replace

Phones: when battery health drops below 80%, or you can\'t make it through a typical day. Laptops: when capacity drops below 80%, or runtime is half what it used to be.

Where to get it done

• Apple Store / Genius Bar — iPhone $89–$99, Mac $159–$249
• Best Buy Geek Squad — most makes, often same-day
• uBreakiFix or local repair shops — often cheaper, ask about parts warranty
• Carrier store (Verizon, AT&T, T-Mobile) — for phones under warranty or insured

A note on DIY

Modern phones and laptops use glued-in batteries. DIY kits exist (iFixit) but the risk of a punctured lithium battery is fire. Unless you have prior experience, leave it to a shop.
