If you're asking, "why is my iPhone 12 so slow?", you're not alone. Many users experience performance issues due to a variety of reasons. One of the most common causes is outdated software—if you're not running the latest iOS version, your device may lag or become unresponsive. Other contributing factors include too many apps running in the background, low internal storage, or poor battery health. When your iPhone's storage is nearly full, it can significantly affect overall speed and responsiveness. Background app refresh and heavy widgets can also consume system resources. To improve performance, try clearing app cache, closing unused apps, and deleting unnecessary files or photos. Regularly restarting your device can help clear temporary glitches. Also, check your battery health under Settings—if it’s degraded, it might be time for a replacement. Keeping your iPhone updated and maintained is key to keeping it fast and efficient.
