How to Know If Your iPhone Battery Needs Replacing

13 Jun 2025 2 min read No comments Uncategorized

Is your iPhone struggling to hold a charge? A failing battery could be the culprit. Knowing when to replace it can save you frustration and extend your device’s life. In this guide, we’ll highlight five clear signs your iPhone battery needs replacing and share tips for finding a reliable repair shop near you.

  1. Rapid Battery Drain
    Does your iPhone die within hours, even after a full charge? This is a telltale sign of a worn-out battery.
    Quick Tip: Go to Settings > Battery > Battery Health & Charging to check your battery’s Maximum Capacity. If it’s below 80%, it’s time to consider a replacement.
    “Most customers think their phone is broken, but it’s often just an aging battery,” says Jake, a technician at NYC Cell Phone Repair.
  2. Overheating When Idle
    If your iPhone feels hot to the touch—even when you’re not using it—your battery may be overworking or swelling. Overheating isn’t just uncomfortable; it can pose safety risks.
    “A phone that’s warm in your pocket or during light use is a warning sign of battery issues,” notes a repair expert at Pellicci Phone Repair in Los Angeles.
    Action Step: Stop using your iPhone immediately if it feels unusually hot and consult a professional.
  3. Unexpected Shutdowns
    Does your iPhone power off randomly, even with 20–30% battery left? This happens when a degraded battery can’t deliver enough power during high-demand tasks.
    “Random shutdowns signal that the battery is struggling to keep up,” explains Alex at Quick Fix Wireless.
    Pro Tip: If your iPhone restarts or shuts down unexpectedly, check your battery health and consider a replacement to restore reliability.
  4. Sluggish Performance
    An old battery can slow your iPhone down. Apple’s iOS may throttle performance to prevent crashes when battery health is low, making apps lag or load slowly.
    Replacing the battery can often restore your iPhone’s speed, giving it a new lease on life.
    Try This: After checking your battery health, compare your phone’s performance before and after a battery replacement to feel the difference.
  5. Your iPhone Is Over 2 Years Old
    Lithium-ion batteries typically degrade after 500 full charge cycles, which equates to about 18–30 months of regular use. Even if your phone seems fine, a battery older than two years may impact performance, app stability, and battery life.
    Maintenance Tip: Check your battery health every 6 months after two years to catch degradation early.

  6. When to Act
    Don’t wait for your iPhone to fail completely. Replacing a degraded battery can boost performance, improve reliability, and save you from costly repairs down the line.
