When should you replace your iPhone battery? Definitive guide
Delhi : How long will your iPhone last between charges? One full day, more than that, or less? Your usage will affect a phone's battery life. The amount of time a device may operate before requiring a recharge is known as battery life. Whereas a battery's lifespan is how long it can be used before needing to be replaced. The lifespan of a battery is correlated with its chemical age, which is different from just time passing, according to Apple's support page. It takes into account several things, like how well it was taken care of and how many charge cycles there were.
When batteries chemically age
All rechargeable batteries are consumable components that lose effectiveness as they age chemically. The amount of charge that lithium-ion batteries can hold decreases with age, resulting in shorter periods of time before a device needs to be recharged. This is the maximum capacity of the battery — the capacity of the battery relative to when it was new. Furthermore, Apple warned that a battery's ability to deliver maximum instantaneous performance, or "peak power," may deteriorate.
How to check the battery life of your iPhone
Choose Battery Health and Charging from the Settings menu. Your iPhone will then show details about your battery's capacity, peak performance, and whether it requires servicing after this process.
Notably, the Battery Health screen on an iPhone displays data on maximum battery capacity and peak performance. Your battery capacity can be slightly below 100 percent depending on how much time has passed since the iPhone was manufactured and when it is turned on. When used under typical circumstances, a typical battery is made to retain up to 80% of its initial capacity after 500 full charge cycles.
When can you replace the battery in your iPhone?
If you notice that your iPhone's battery has depleted below 80% of its original capacity, you should consider replacing it.
