Why You Shouldn’t Charge Your iPhone to 100% is quite interesting to know. For most of us mobile phone users, our iPhone is our major daily companion, and since they are useless when off, we would try our best to get it fully charged.
To make use of our iPhone fully well, it is best that we keep it fully charged at all times, but regularly charging it to 100% actually can be harmful to its overall battery health.
Having a healthy iPhone battery is very vital for optimal performance; once it starts to close capacity, for example, you might encounter some unexpected shutdowns or even performance issues. All batteries with time would age, but delaying the process of aging might actually keep your batter useful for an even longer time.

Here’s Why you Shouldn’t Charge your iPhone to 100%
When it comes to consumer gadgets like headphones and power banks, all iPhones are powered by lithium-ion batteries, that with time deteriorate a bit every time they get recharged. The more often you recharge your phone’s battery to 100%, the quicker its lifespan gets reduced.
Although researchers are working on the development of the next generation battery tech, lithium-ion remains the best option for any smartphone at the moment. Apple explains why on their website, stating that lithium batteries “charge a lot faster, last longer, and possess a much higher power density for more battery life in a lighter package.”
As stated by the company, iPhone batteries are built to retain up to about 80% of their original capacity right after 500 complete charge cycles (via Support). If the maximum capacity drops below 80% or its recharge cycles exceed 500, then it might be time for a battery replacement.
It is very important to mention that there are other conditions that can actually contribute to the degradation of the battery aide the inevitable chemical aging that comes with constant charging name, as Apple notes on its website, exposing an iPhone to high heat regularly or for long periods of time can actually cause you to lose capacity much faster than expected.
How to Check iPhone’s Battery Health
Apple has offered a way for users to keep tabs on the health of their battery so they can be making use of the changes as required. Under Settings > Battery > Battery Health (via Apple Support), you would be able to see your iPhone battery’s charge capacity, with about 100% being the maximum.
This feature happens to be Apple’s attempt at transparency right after its infamous Baterygate scandal, which exposed the company’s silently throttling performance on much older iPhones.
Another great transparency-oriented feature happens to be the peak performance capability report, which happens to be a one-liner that reveals if your iPhone is working at normal levels or if its performance has gotten impacted by poor battery health.
You get to find your Phone’s performance capability by navigating to the same battery health section as previously stated: Settings > Battery > Battery Health. When you get there, and you find this message “Your battery is currently supporting normal peak performance,” then your iPhone is working within Normal Parameters.
How to Enable Optimized Charging on Your iPhone
Apple also has chosen to work on a built-in feature called optimized charging that essentially does what its name is suggesting. By minimizing the amount of time that your iPhone is fully charged, Optimized Charging would help you with delaying the chemical aging of its battery. When you turn on this feature, your iPhone charging would slow down after 80% in certain specific conditions, but, unfortunately, these conditions aren’t yours to set.
As stated by Apple, the iPhone Makes use of on-device machine learning to help understand how often you charge it, and when it figures out that you have plugged your Phone for a while, it would turn on Optimized Battery Charging.
It is very likely that this feature has been enabled on your iPhone. When you first set up the device or after updating it to iOS 13 or later, Optimized Battery charging would be turned on by default. To be sure that the setting has been enabled, head to settings > Battery > Battery Health and check that the optimized battery charging option is on.
Once this is enabled, you would get a notification on your screen, telling you when your iPhone would be fully charged. If you need to skip trickle Charge and get to 100% faster, just simply tap and hold the notification and select Charge now.
