What Causes iPhone Battery Problems?

Over time, your iPhone's battery naturally loses capacity — but certain habits and conditions can accelerate this process. Here are the most common causes we see at our Chicago repair centers:

1. Overcharging and Overnight Charging
   Keeping your phone plugged in for hours after it reaches 100% stresses the lithium-ion cells.
2. High Heat Exposure
   Leaving your phone in a car, pocket, or near a heat source can permanently degrade battery health.
3. Excessive App Usage & Background Activity
   Constant multitasking, GPS tracking, and high-brightness settings can quickly drain and strain your battery.
4. Faulty Charging Cable or Port
   Using low-quality chargers or a damaged charging port can cause irregular charging and battery failure.
5. iOS Updates & Software Bugs
   Sometimes, software updates or background processes can increase battery drain, which may persist until the device is recalibrated or replaced.
6. Battery Age
   Most iPhone batteries are rated for 500 complete charge cycles. After that, performance starts to decline noticeably.

If you’re noticing fast battery drain, sudden shutdowns, or slow charging, it’s time to replace your iPhone battery.
