iPhone batteries degrade over time due to the natural life cycle of a battery. This is measured in cycles, with one cycle being the battery draining from 100% to 0% and then recharging back to 100%. An iPhone battery has around 500 cycles before it starts to degrade. As the battery’s capacity diminishes, it drains faster and needs to be recharged more often, affecting the phone’s performance.
You can check your battery’s health under Settings > Battery > Battery Health > Maximum Capacity on your iPhone. If your iPhone battery needs replacing, the most convenient and reliable way is through Apple. The cost for this service is $69 for an out-of-warranty model not covered by AppleCare+. However, you can also replace the battery yourself or get it replaced at a third-party repair shop. It’s important to understand the process and make an informed decision.
