While a slightly lower percentage is lower as your phone ages, it should still retain about 80% of the capacity at 300-500 charge cycles. If it starts dropping below 80%, it's time for a battery replacement.
Apple considers any iPhone with a battery capacity of 80% or above to be in optimal condition. In fact, Apple feels so strongly about battery health that its 1-year warranty covers any battery at 80% capacity or more. It's not unusual to see iPhones that, after one year, still have a battery capacity of 95% or above.
Replace the battery when the battery life bothers you enough to convince you it's necessary to spend the money on a new battery. An 80 percent battery health level should still be enough to get you through the day for most users. However, at 40 or 50 percent of battery health, things start degrading really rapidly.
An iPhone battery is considered healthy if its maximum capacity is above 80%. If your iPhone battery is at 70% of its original capacity, it may be starting to lose some of its performance and may not last as long as it used to between charges.

Is 75% bad battery health?
100% is factory-fresh, and iPhones can run extremely well with batteries as low as 80% performance in Maximum Capacity. If your iPhone's battery health has slipped to 75% or below, it will still perform well. However, you can expect further degradation and may see lower numbers and worse performance in the near future.
When to replace the iPhone battery. If your iPhone's battery health is less than 80% and you're getting lower screen-on-time, it's probably the best time to replace the battery. If you're noticing frequent app crashes or frame drops, the battery could be at fault, and it's best to change it.
82% would be about normal for 2–3 years of use. The bottom line is this: if you aren't bothered by the battery life in your phone, then don't worry about it. If it seems to run out of juice faster than you would prefer, then get the battery replaced.

What happens if iPhone battery health is below 85?
However, at 79% and below, your battery is officially considered degraded. But, what if the percentage is somewhere in the middle? In general, if your iPhone's battery health is at 85% or 90%, your phone should still be operating at an optimum level for another six months to a year.
It is based on full charge cycles, and is rated at 500 full charge cycles to 80%. So at 85% that implies that you have used 350 full charge cycles. Possible, but unlikely in less that a year unless you charge it multiple times a day from 0% to 100%.
If you are the average person, using your iPhone normally each day and charging it only every night, after 1 year, your iPhone's battery health should be around 95%.
Apple considers any iPhone with a battery capacity of 80% or above to be in optimal condition.

It's not unusual to see iPhones that, after one year, still have a battery capacity of 95% or above.

Are there any side effects of changing iPhone battery?

If your phone has already lost battery health, then there is nothing one can do other than replace the battery. As the battery capacity decrease is directly proportional to the chemical composition of the battery and once it comes down, there is no way to take it back to 100 percent.
