how to maintain iPhone battery health

Ever since Apple introduced the Battery Health feature to iPhone and iPad, users can keep an eye on their battery easier now. But, it also means that you have to see your iPhone battery health decrease from time to time. Sadly, it’s impossible to keep any battery’s health at 100% forever. However, even below that perfect percentage, your iPhone can still deliver peak performance. Following these tips below to ensure that your iPhone battery will remain in good health for a long time.

Let’s Check Your Battery Health First

Well, at least we need to know much damage has been done first. If the result is lower than 80 percent then your battery is considered worn.

Go to Settings > Battery on your iPhone and select Maximum Capacity. This will show you how much charge your battery can hold relative to when it was new. 

Also, there is a Peak Performance Capability section that informs you whether your battery can provide enough power to your iPhone when it’s under heavy load. And, if your battery health drops below a point where it’s incapable of sustaining peak performance, you will see a warning.

Avoid Extreme Temperatures

The recommended operating range is 0° C to 35° C (32°F to 95° F). Although, it’s not practically possible as a lot of places have temperatures way beyond the recommended operating range. So, you can either use cases to keep your iPhone warm or avoid leaving it exposed to other heat sources too much on a hot day.

On top of that, charging also generates heat, so your iPhone may heat up while charging. If that’s the case, then you should remove your iPhone’s cover to ensure that the heat generated during charging is dissipated properly. 

Additionally, you should avoid using your iPhone when it’s charging too. Don’t worry about charging overnight. Lithium-ion batteries with smart management software that ensure your iPhone don’t overcharge. 

Use Original or MFi Certified Chargers

Make sure to go for the original charger, or get an MFi-certified one for your iPhone. This tip is generally to protect you against shady, knock-off chargers that can damage your battery health and do more harm than good. In fact, every lighting cable adapter has a tiny authentication chip that tells your iPhone that it’s MFi certified. Otherwise, your iPhone will show a pop-up when it detects the cable is not MFi certified. 

Avoid Completely Depleting Your Battery

Nowadays, most smartphone batteries have a structure like this:

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

The danger zone is the grimy area from where you could recover. But, there’s no guarantee after crossing the line because doing it might damage your battery capacity permanently. So, it’s not recommended to drain your iPhone’s battery to 0% unless you’re calibrating it. In case you have an erratic schedule, you can go charger hopping through the day as it’ll only be counted as 1 full charge cycle, once the battery completes 100% discharge.

Enable Optimized Battery Charging 

This feature was introduced with iOS 13 and it can actually increase the lifespan of your battery. You can enable it by going to Settings > Battery > Battery Health. When it’s on, your iPhone will start analyzing your charging routine to determine when it should fully charge its battery. Doing this keeps your battery below 80 percent until a full charge is needed, reducing unnecessary battery aging. And, you can tap the “Charge Now” option to charge it to 100% if needed.

Use Dark Mode

How to use Dark mode on iPhone

We finally have dark mode on iOS 13. According to a recent test, the dark mode can actually extend your iPhone’s battery life by 30%. Therefore, using it for longer periods reduces the stress on your iPhone’s battery, hence improving its health. And, the dark mode is not only good for your iPhone’s battery but also soothing to your eyes. So, it’s a win-win situation!

Force Quitting Apps Does Not Save you Battery

“Force quitting apps to save battery life on your iPhone” is still a thing in 2020. And, people do this because they believe it can save more energy and their iPhone’s battery lasts longer. In reality, force quitting apps actually decrease your iPhone’s battery life.

With the new iOS, the operating system moves apps in different states when they’re running in the background. There are 5 states: Not running, inactive, active, background, and suspended. So, when an app is forced to close, it’s removed from memory (the suspended state of the app) and closed. Upon relaunching, more resources are required to run the app all over again, leading to more battery consumption.

The Bottom Line

Battery health is important for the longevity of your iPhone. Unfortunately, you cannot restore your battery capacity with these tips. However, it’s also important to remember that, no matter what, at one point you will need to change your iPhone’s battery or buy a new smartphone. Try to not let it get in the way of actually enjoying your experience with an iPhone. And, if you have any questions, let us know in the comments!
