In order to activate Wi-Fi, swipe down the upper right on your screen to access Control Panel. Tap on the Wi-Fi icon and activate Wi-Fi.


    13. Be careful about temperature


    Nobody likes extreme temperature, whether it’s your pet, you, or your iPhone battery. If you are trying to find out how to increase maximum capacity of iPhone battery, this is one of the critical points. Extreme heat and extreme cold both are harmful to an iPhone battery. If you live or work in an area of extreme cold or extreme heat, use your phone with care. Consider using a heatproof phone case and avoid direct sunlight or cold contact.


    What is the optimum battery condition of iPhone?


    All iPhone devices come with 100% battery capacity. But Apple officially claims that 80% is the optimum battery condition for iPhone devices. They always make sure the optimum battery performance lasts for at least a year. It is also covered by the warranty, which is applicable if any iPhone device battery falls below 80% in one year. You can also check your battery health status by going to Settings>Battery>Battery health.


    What ruins iPhone battery health?


    Besides aging, some other factors also cause battery capacity degradation. Such as external or internal damage, temperature fluctuation, device usage, charging routine, environmental factors, etc.


    1. External or internal damage


    If a device is damaged or dented somehow due to drop or water spillage, the battery may behave abnormally and lose capacity. You may notice excessive heat, or maybe your phone suddenly shuts off during usage. To prevent unwanted damage to your iPhone, try to use a soft silicon or shock absorber phone case.


    2. Temperature fluctuation


    Any Li-ion battery operates better and lasts longer at room temperature. But in certain situations, the temperature limit may stretch from 0℃ to 35℃. Any random fluctuation of temperature or using the device longer in temperature over 35℃ or below 0℃ also degrades the battery capacity.


    3. Device usage


    Use pattern of the device can also be a cause of battery capacity. Frequent gaming or using high brightness on the screen will degrade the performance quicker. Also, try not to use your device while charging.


    4. Charging routine


    If you regularly use your device to 5% charge and charge it up to 100% again, the battery capacity will degrade more quickly. Batteries tend to perform better at 50-65% charge level. But if you require more screen time, consider charging to 85 to 90% and start charging again around 15% charge level.


    5. Frequent use of fast charging


    Although fast charging sounds convenient, it comes with a fair share of problems. Using fast charging regularly degrades battery lifespan. Due to heat generation during charging, the battery loses its charge holding capacity faster.


    6. Using wireless charging


    Extensive use of wireless charging will also degrade the battery life quicker on the iPhone. Wireless charging is usually very inefficient and produces quite a lot of heat. As we discussed before in this article, heat is quite bad for Li-ion batteries.




    In this post, we tried to answer a decade-long question of how to increase maximum capacity of iPhone battery. Any type of chemical battery is a naturally degradable component. Hence, they will eventually fall victim to degradation. Yet you can slow the degradation process by simply following the above procedures.
