Complete Battery Replacement Guide (iPhone & Android)

Battery issues like rapid draining, unexpected shutdowns, and swelling can seriously disrupt your smartphone experience. Batteries wear out over time — and unlike screens, they replace the core power system of your device. This guide will walk you through signs you need a new battery, repair options, costs, and long-term battery care.

When a Battery Needs Replacement

Watch for these common signs:

• Phone dies at 30% or more
• Swollen battery lifting the screen
• Overheating during normal use
• Slow charging or not charging at all
  These all indicate a failing battery requiring replacement.

Why Timely Replacement Matters

• Restores performance and battery life
• Prevents further damage (swelling can pop screens/components)
• Avoids unexpected shutdowns

Battery Replacement Options

Authorized Service: Uses genuine parts and preserves warranty where possible.
