The error that damages your iPhone's battery and how to avoid it

Most cell phone batteries are designed to last a day or more. It all depends on usage, of course, because those who are constantly connected will need to recharge them more often.

Furthermore, many people believe that the best thing for their phone is to always keep it fully charged. To achieve this , they leave the device charging overnight and avoid unplugging it until the battery reaches its limit.

However, today's batteries don't always do well being fully charged or left at 0%. Experts agree that a mid-range is necessary.

This popular advice among users of phones with Android operating system, also applies to those who use iPhone , with iOS operating system .

A few months ago, a study conducted by Stanford University revealed that the best charging range for extending battery life is between 20% and 80% . This prevents chemical wear on the component and also reduces the number of complete charge cycles, which are responsible for battery performance loss over time.

At this point, it's worth clarifying that a full charge cycle is completed when the phone is charged from 0 to 100%. If you do this once a day, you'll have used more than 300 cycles in a year . Therefore, experts advise charging only when necessary and avoiding charging at 100%.

iPhone users have a feature that allows them to leave their iPhone plugged in overnight without charging it to 100%. To do this, you must have Optimized Battery Charging enabled . To check this, go to Settings, Battery, Battery Health & Charging, and then make sure Optimized Battery Charging is enabled.

Another feature that gives you more control over your iPhone's battery is Charge Limit , which prevents it from reaching its maximum capacity, helping to reduce battery drain. On iPhone 15 or later, go to Settings, Battery, and then Charge . Under Charge, you can choose a percentage in 5% increments, between 80% and 100%.

Apple experts say a charging limit can improve battery life. Even if you only limit charging to 95%, this feature can have long-term benefits.

However, you shouldn't worry if your phone remains plugged in when the battery is full. In addition to Apple , other manufacturers use software designed to minimize these factors and even offer customers the ability to control them if they wish.

Beyond these features, some tips for preserving your battery are always helpful: avoid letting it drop to 0% or even reach 100% (remember that the ideal charge level should be between 20% and 80%); avoid leaving it plugged in all night ; remove the case if it gets too hot while charging; avoid charging in direct sunlight or in very hot, enclosed spaces; close any apps you use to reduce power consumption; activate power saving mode or lower the screen brightness.
