iPhone users are increasing with each each iteration, accounting for over 25% of the global market share. However, with all of the new functions and capabilities, customers are always concerned about whether or not their iPhone’s battery will survive the entire day.

Lithium-ion batteries are used in iPhones and practically every other Apple product. In comparison to ordinary batteries, they charge faster, last longer, and weigh less. However, the capacity of all Lithium-ion batteries depletes over time.

In basic terms, they deteriorate as the equipment ages. Even if you’re not using your iPhone, you’ll notice that you’re charging it more frequently than you used to and getting significantly less screen time and battery life as the battery ages.

This is when the term “iPhone battery health” comes into play.

The amount of time a gadget may run before it needs to be recharged is referred to as “iphone battery life.” The amount of time a battery lasts before it needs to be replaced is referred to as “iPhone battery lifespan.” The battery age is measured in charge cycles, while the battery life is measured in percentages and hours. Apple claims that

When operated under normal conditions, a typical battery is designed to retain up to 80% of its original capacity after 500 complete charge cycles. Service coverage for a damaged battery is included in the one-year guarantee. If it’s out of warranty, Apple will replace the battery for a fee.

Here are ten things to do to improve the battery life of your iPhone:

1. Extreme temperatures should be avoided.

Extreme temperatures can damage lithium-ion batteries. Apple has also released an official temperature range for iOS devices’ comfort zones.

0°C to 35°C (32°F to 95°F) is the suggested working temperature range. It’s not feasible, though, because many sites have temperatures much above the authorized operating range. As a result, you can either use thick cases to keep your phone warm or avoid keeping it out in the sun on a hot day.

Also, avoid leaving your iPhone in enclosed locations (such as automobiles) with little ventilation because it raises the room temperature. Many individuals leave their phones in their automobiles or in the glove compartment, which boosts the temperature of the phone.

Heat is an iPhone battery killer because it permanently reduces the capacity of the battery. Extreme cold temperatures, on the other hand, have a short-term negative impact on the battery’s health.

It’s also not a good idea to charge your iPhone battery in extreme temps, so make sure you keep it in “pleasant temperature zones.”

2. Keep the battery from being entirely depleted.

Almost all Lithium-ion batteries have the following structure:

[Usable capacity] (Overcharge Protection Buffer) *Danger Zone* – [Total Cell Failure] – (Under-Voltage Protection Buffer)

The danger zone is a filthy area from which you might be able to recover, but there is no assurance of performance afterwards. As a result, the iPhone’s battery capacity is irreversibly harmed.

So, unless you’re calibrating the iPhone, it’s not a good idea to reduce the battery to 0%. If your schedule is irregular, you can go charger hopping throughout the day because once the battery reaches 100 percent discharge, it will only be counted as one full charge cycle. Find out what constitutes a full battery charge cycle.

3. Allowing your iPhone to overheat while charging is not a good idea.

Heat, as previously said, is a battery killer. As a result, ensure sure your iPhone doesn’t overheat while charging. According to Apple, heat damages the battery capacity permanently, whereas extreme cold weather merely affects the capacity briefly.

Heat can cause the internal structure of the battery chemicals to alter, causing the voltage indication to be damaged even more. A faulty voltage indication will be unable to optimize current flow, resulting in overcharging of the iPhone and eventual battery and iPhone damage.

4. Only MFi charging accessories should be used.

The use of charging accessories that have not been certified by Apple is one of the most common causes of poor iPhone battery health. Always double-check that the charging cable and adapter are both MFi approved.

Made for iPod, Made for iPhone, and Made for iPad is abbreviated as MFi. The MFi logo can only be used on goods that pass Apple’s stringent device and facility tests. As a result, keep an eye out for the MFi emblem on charging accessories.

Every lighting cable adaptor, for example, contains a tiny authentication chip that informs the iPhone that it is MFi authorized. Otherwise, when iPhone detects a cable that isn’t MFi approved, it displays a pop-up.

5. Optimised iPhone Battery Charging should be enabled.

With iOS 13, Apple introduced optimized battery charging, which extends the life of your battery and thereby improves its health. It learns from your everyday charging behavior to estimate when your iPhone will be charged for a longer amount of time and charges accordingly.

Many people, for example, have developed the habit of charging their iPhones overnight. As a result, the machine learning system will try to ensure that the iPhone is fully charged by the time you wake up (based on your previous charging and unplugging data). This is done by the algorithm to ensure that the iPhone is charged in less time.

When you enable the feature, it will display the time when your iPhone will be fully charged. You can charge it to 100% right away by tapping the “Charge Now” option.

6. Auto-brightness should be enabled, and full brightness should be avoided.

The retina displays in iPhones use a lot of power. The iPhone’s screen is one of the most used and battery-draining components. Pushing those retina display pixels to full brightness puts a strain on an iPhone’s battery. As a result, keeping your iPhone’s brightness at 100 percent all of the time isn’t a good idea because it has a direct impact on the battery’s health. Switching on auto-brightness can enhance your iPhone’s battery life in the long term by adjusting the brightness settings based on the surroundings. Furthermore, it is beneficial to your eyes.

7. During charging, remove the cover.

Because charging produces heat, your iPhone may become warm when charging. If this is the case, you should remove the cover from your iPhone to ensure that the heat generated during charging is appropriately dissipated. Some thick cases and coverings retain heat, causing the iPhone to overheat when charging unnecessarily. This could jeopardize the iPhone battery’s health. It’s most popular in thick leather foldable cases with card pockets and other small access features. If you have one of those big, thick rubber cartoon covers, don’t charge your iPhone in it because it will overheat.

8. Fast charging isn't necessarily a bad thing for your iPhone Battery.

For those who are curious, fast charging is not harmful to your iPhone battery (unless it isn’t officially supported). Fast charging is officially supported on iPhones released after 2017 (iPhone 8 and higher), as long as you use an Apple-approved fast charger or an MFi-certified charger.

Fast charging is done in two stages. The charger pumps electricity into the battery at a quicker pace in the first phase, known as rapid charging. You may have noticed how businesses advertise this with slogans like “60% battery in 30 minutes of charging.” Because Lithium-ion batteries are made up of molecules whose structure changes when they absorb electricity, this is the case. A low-charge battery can be charged more quickly without causing damage.

Fast chargers are not harmful to your iPhones. However, when compared to the slow 5W chargers, they still produce more. So, if you have the extra time, I’d recommend letting your iPhone charge slowly. When compared to slow 5W charging, fast charging works in phases, and the initial burst phase still generates a lot of heat. Heat, as previously said, is an iPhone battery killer. So, use the 5W wherever possible, but don’t let this influence your charging or usage habits. The iPhone is supposed to help you rather than the other way around.

9. Charging for the night

Many individuals, let’s face it, have the habit of charging their iPhones overnight. On a single charge, our phones don’t last very long. However, “Don’t charge your iPhone overnight for the sake of your battery!” is a prevalent fallacy among iPhone owners. Let’s get that out of the way.

Lithium-ion batteries are used in modern smartphones, and clever battery management software ensures that your phone does not overcharge.

Similarly, iPhone batteries include a cutoff point to prevent overcharging of the device’s battery. This helps to keep your iPhone’s battery healthy.

Furthermore, you may enable Optimized iPhone battery charging to ensure that you have 100 percent charge when you get up every morning without having to worry about the battery being damaged by overnight charging.

10. Make use of Wi-Fi.

Wi-Fi is well-known for using less power than cellular radio. Because Wi-Fi is typically faster than cellular, it downloads and uploads things even faster, so you and your iPhone won’t have to wait as long. For example, if you’re watching a YouTube video on Wi-Fi instead of cellular, your iPhone will download the video faster (while you’re watching it), resulting in less screen time and battery consumption. In the long run, this improves the battery health of your iPhone. However, there is a disadvantage to using Wi-Fi. In the following section, you will learn more about this.
