🗓️ March 27, 2023 By ✍️ Jaysukh patel

Apple has come up with a considerable wide range of phones, keeping up with its tag of excellence and high-tech advancement and innovation. However, while choosing a phone, its battery life is one of the most important factors we consider. It hardly matters if you possess the most recent, fastest, and most powerful devices in the world if the battery doesn’t last throughout the day. iOS 11.3 and later, improved numerous performance management features of iPhone. And it has been done by periodically assessing the level of performance management necessary to avoid unnecessary glitches and shutdowns. 

As per Apple, if the battery health can support the observed peak power requirements, power performance will be lowered and improved. Furthermore, if the unexpected shutdown of the device still occurs again, then performance management will also increase. This kind of assessment enables apple to develop more adaptive performance management. Apple can solve the battery longevity problem by using a larger capacity battery. But it will be useless if you don’t play your part too! 

The most important thing is that battery life also depends on how we care and use our phones, their battery. The usability and care can decay its battery life, and your iPhone won’t last long. There are numerous myths and bits on iPhone uses. For example, considering that iPhone doesn’t like high temperatures, especially when charging. You can do many things to help your iPhone live longer for iPhone safety. To know more, continue reading this article.

But the good news is that iPhone has an Optimised Battery Charging Feature, so you can plug it in all day, depending on when you want to use the phone as your daily routine. At 80%, it will either wait to finish charging or start charging slower than normal to prevent battery aging and maintain its life. So even if you keep your phone in charge for a more extended period, you will still find your phone charging at 90%. iPhones and Smartphones technology has evolved immensely to detect when they are 100% and still won’t overcharge. Still, it is best if you don’t overcharge your phone at any time of the day.

Is it okay to use iPhone while charging?

With our habit of frequently using our phones, we are pretty dependent on them. We wait till our battery is at the optimum percentage of charge. And start using it immediately after it is fully charged. But can we use it while charging? Yes, one can use the phone while charging; it is safe. This does not affect the battery. 

But if you are doing something in your device that is processor-intensive, it might slow the charging a little. This slows the charging rate slightly as the energy obtained from the power source applies in operating the phone, and the battery gets charged with the remaining power. And ultimately, the phone’s performance over time may seem to be affected.

iPhones are designed to deliver an excellent experience that is simple and easy to use, it emphasizes advanced and sophisticated engineering for the battery. One of its important technology areas is battery and its performance. It is a complex technology, and several variables contribute to battery performance. So please don’t make it a habit of using the iPhone while charging every time because when batteries age, it even contributes to changes in iPhone performance. 

At what percent should I charge my iPhone battery?

As we all want our Gadgets to be utilized according to our daily routine and constantly depending on our phones, it is still recommended to avoid charging your iPhone 100% every time you charge. Similarly, you should avoid discharging or using the phone until it drains its battery to 0%. 

It is best to keep your phone charged between 30% to 80%, and we know that it is not always possible with our hectic routine and constant dependency on our phones. Here, the IOS 13 feature of the optimized battery charging feature makes the iPhone wait to charge fully and enables you to adjust it according to your daily use.

Always remember, if you want to store your device long-term, two key factors play a significant role in it: the environmental temperature and the percentage of the charge on the battery when it’s powered down for storage. Therefore, it is recommended not to fully charge or fully discharge. Because if you store a device when its battery is fully discharged, the battery could fall into a profound discharge state, making it incapable of holding a charge. Contrarily, if you fully charge the phone for an extended period, the battery may lose its capacity, leading to its shorter battery life. 

The battery of an iPhone maximum capacity depends on the peak performance and its uses. The Battery Health screen highlights the information about the maximum battery capacity. A maximum battery capacity measures the device battery capacity relative to when it was new. As time passes, the battery’s capacity will decrease as the battery chemically ages, resulting in fewer hours of usage between the charges. This declined life of the battery drastically changed from the time of its manufacturing till the date. 

A normal iPhone battery can retain up to an optimum 80% of its original capacity at a 500 complete charges cycle when operating under normal circumstances. Moreover, the one-year warranty of the device also includes the service coverage of the battery as well. 

What happens if you keep your iPhone charging after 100?

Earlier the technology was not as improved as today’s advanced software design. Today’s devices, specifically for an iPhone 8 and later, has incorporated more advanced hardware and software. It is designed to provide a clear understanding and depiction of the phone’s performance. Moreover, it even provides a more accurate estimate of both power and the battery’s power capability to maximize the overall system. 

Incorporating the feature optimized battery does not overburden the device with an excessive power supply. The optimized battery feature ensures that it charges slowly after 80% and stops consuming the power supply once it becomes 100%. But still keeping the phone on charge even after it becomes 100% is not recommended, as a battery life tends to age chemically. So, the performance of the battery may significantly diminish.

How to maximize the battery performance?

When it comes to “Battery life”, it is the amount of time a device performs or runs before the battery drains out and needs to be recharged. It is the amount of battery that lasts until it needs to be replaced. 

The battery life and lifespan is immensely affected by the mixture of things you do with your device. A battery’s lifespan relates to the ‘chemical age’. This occurs over time, precisely because of the recharge cycles and the device’s usability. However, using and maintaining an life of device can be tricky, but it is not much more challenging than it seems. One can follow certain tips to extend the battery life of an iPhone. 

Tips for longer life of the battery:

  • Keep the device in a good cool, moisture-free environment that records a temperature less than 90°F (32° C).
  • If you think about storing the device for more than six months, charge it to 50% every six months. 
  • It is recommended to power down the device to avoid additional battery drainage.
  • Switch to low power mode- it will enable extended battery life.
  • Keep phone half-charged when its stored for a long term.
  • Avoid charging or leaving the iPhone in hot environments, including direct exposure to the sun for an extended period of time. 
  • Don’t overcharge to 100% or even over drain the battery till 0%.
  • Always update your iPhone, as Apple software updates often include advanced energy-saving -technologies.
  • Remove certain phone cases during charging.

Remember, depending on the time of use and how long you store your device, and it may remain in a low-battery condition when you remove the device from long-term storage. So, when it’s removed from storage, it may additionally require 20 minutes of charging with the original adapter before you can try it. 


iPhone batteries use lithium-ion technology, which are more advanced than the older generation of technology. Lithium-ion batteries charge faster, last longer, and have a higher power density for more battery life in a lighter package.

This batteries technology provides the best technology for your device user experience and device. However, always remember that all rechargeable batteries are consumables and limited lifespan. And eventually, their capacity and performance decline such that it requires replacement. And as the battery chemically changes, it even contributes to changes in the performance of the iPhone.
