iPhone Battery; How Much Battery Health Declines in A Year-wise Summary Details; All You Need to Know

By battery health, the average iPhone user around the world is worried, yet another feature available in their mobile phone. Battery health is at its high level, displayed to the fresh user, such as 100%, and declines with use, but it raises a major question: How much does an average iPhone's battery health decay in a year? And many people would definitely be looking for what could have been done to prevent it, so I am going into the details.

Average Decline Rate of Battery Health Each Year in iPhone

According to the official statements from Apple, an iPhone battery is expected to hold at least 80 percent of its charge after around 500 full charging cycles. A full cycle means that the battery has been charged from zero to maximum (100) once a day; thus, you will count around 365 charge cycles in a year. In effect, under normal use patterns, therefore, the battery health is said to decline by an average of about 5-8 percent every year.

For Instance

At the end of First Year: 92%-95%.
At the end of Second Year: 85%-90%.
This may vary according to your pattern of use, charging habits, and temperature.

What Causes Battery Deterioration?

Lithium-ion batteries are used in iPhones. Degrading chemically over time, such causes include:

A high number of charge cycles – Repeatedly charging and discharging fully.

Heat: Excessive heat destroys a battery.

Fast charging and unauthorized chargers.

Heavy gaming or using heavyweight apps, which produce excess heat.

Reduce battery health depletionTips

Always keep optimized battery charging ON.

Charge levels must be between 20-80%; do not discharge to 0%.
Use only official Apple charges or certified chargers from reputable departments.
Avoid hot places.
Do not charge overnight, do not take long charging hours.

When to Change Battery

Apple recommends replacement batteries when battery capacity measures below 80% or less than the backup time becomes considerably less. Using the authorized repair center to change the battery will then give the phone a new lease of life.

Normal usage will lead to a drop of between 5%-8%. Careful use can reduce this decline noticeably. Batteries do grow old with time, but proper conscious use of them can make them last fairly long before they grow old.
