iPhone Battery Replacement

While there is no fixed life for an iPhone battery, it totally depends on the model of the iPhone and the kind of usage. Each battery is typically designed by to last for 500 charging cycles. You complete one charge cycle of your iPhone Battery when you have used an amount that equals 100 percent of your battery’s capacity — but not essentially from one charge. It can take several hours or days to complete one charge cycle depending on the usage.

Your battery is designed to retain up to 80 per cent of its original capacity at 500 complete charge cycles. If you have not completed the charging locations and still your battery does not provide enough backup then you can try re-calibrating your battery. Let your battery drain to 0% and then charge it to 100%. Once your battery is charged to 100% discharge the battery back to 0%. This will recalibrate the battery. Once you recalibrate the battery, use the phone normally and see if your battery is still draining too fast or taking time to charge. If the charging time has increased or if the battery does not last for long then you have to get your iPhone battery replaced.

Yes. It is not recommended to continue charging your iPhone beyond 100% as it affects the life of the battery.

It is not recommended to replace the battery yourself since it requires the right tools and knowledge. ESD protection is needed to protect your iPhone from being damaged. However, if you are familiar with these concepts then you can do the replacement yourself.
