What does the battery percentage (Battery Health) mean on an iPhone and why is it important to monitor it?

With the growing demand for refurbished iPhones in Bulgaria, especially from proven retailers like Hop.bg, one question is becoming more and more frequently asked by users - what does Battery Health actually mean and why is it important to monitor it? In today's article, we will tell you what the battery health of an iPhone is, what the Battery Health percentage shows, how it affects the performance of the phone and what to expect when buying a refurbished model.
1.What is Battery Health on an iPhone?
Battery Health is a feature introduced by Apple in 2018. in order for users to be able to monitor the current battery health of their iPhone. It is measured in percentages and shows how much of its original capacity the battery has retained from the moment of purchase to today.
You can check it easily. To do this, go to "Settings", then go to "Battery", click 'Battery Health & Charging' and finally 'Maximum Capacity'. For example, if your iPhone shows 88% Battery Health, it means that the battery can now hold 88% of the charge it held when it was brand new.
2. How does Apple measure Battery Health?
Apple calculates Battery Health through a combination of the number of charge cycles, operating temperature, battery load, and charging habits. With normal use, after about 500 full charge cycles, a battery loses about 20% of its capacity, which means a Battery Health of about 80%.
3. What percentage of Battery Health is considered good?
If the phone's Battery Health is between 100 and 90%, then its condition is excellent and does not need to be replaced. At percentages between 89 and 80, the battery is in good condition, which is normal for a refurbished iPhone. If the Battery Health percentages fall into the range between 79 and 70, you can now consider replacing the battery. Anything below 70% Battery Health means that battery replacement is recommended. Hop.bg Battery Health is listed for every refurbished iPhone.
4. How does Battery Health affect iPhone performance?
The following issues may occur as Battery Health decreases:
Shorter time between charges
Slower performance – Apple reduces performance to prevent reboots
Slower charging – the system adjusts power when the battery is worn out
Possible unexpected shutdowns – especially with Battery Health below 80%
5. How to keep Battery Health longer?
You can’t bring the percentage back up, but you can slow down its decline by doing the following:
Use original or certified chargers
Avoid high temperatures
Don’t leave your phone completely discharged or constantly at 100%
Enable Optimized Battery Charging (Settings → Battery → Battery Health & Charging)
6. When should you replace your iPhone battery?
Apple recommends replacing the battery in cases where Battery Health drops below 80% or a message appears such as "Battery Health significantly degraded." or "Your battery’s health is significantly reduced.". At Hop.bg, refurbished iPhones with Battery Health below 80% must receive a new battery, and this is clearly noted in the product description.
7. What does Hop.bg offer regarding Battery Health?
