How to Check iPhone Battery Charge Cycles

Whether you have noticed an unexpected battery draining issue on your iPhone and can’t figure out what’s ailing the device or you are curious to know if the battery is still good enough to deliver peak performance, checking iPhone battery’s cycles can dispel the doubts. Just like anything else, iPhone’s battery ages with time. And when it becomes too weak to take on tasks with the same efficiency, you may notice significant slow down in speed and a drastic reduction in battery life. In some cases, the worn-out battery may even cause the iPhone to shut down randomly. Thankfully, you can check the battery cycle count of your iPhone to find out if the battery is ready for replacement.

How to Check Battery Cycle Count of Your iPhone

Understanding Battery Cycle Count of iPhone

Wondering what is a battery cycle? Well, a cycle count means draining all of your battery’s power and then fully recharging it.

What if you plug your iPhone for charging even before it still has plenty of battery left, will it still be called one cycle? Nope!

Supposing you have charged your iPhone to 100% and then depleted the 70% battery before plugging the device again for charging. Now, your next cycle count will begin only after you have drained the remaining 30% battery.

How Long iPhones Can Deliver Peak Performance?

As per Apple, iPhone batteries can retain up to 80% of its original capacity at 500 complete charge cycles in a normal use case. Bear in mind, the actual scenario may differ based on the tasks your iPhone is handling.

When the number goes below 80%, that’s when the problem begins. And things like longer app launches, lower frames, and the sluggish performance tend to become a norm. That’s a clear indicator of a worn-out battery, which needs a replacement.
