10 Useful Tips to Maintain 100% iPhone Battery Health

Once you update your iPhone to iOS 11.3, you can check your iPhone’s total battery capacity with the Battery Health function. So, in this post, I’m going to provide you top 10 useful tips in order to maintain 100% iPhone battery health.

However, The Maximum Capacity Readout gives an estimate of the total capacity the battery will carry. New phones are expected to report a 100% iPhone battery health. Lower Maximum Power means the iPhone won’t last as long between charges. Apple says that the iPhone that used 500 cycles should still retain around 80% of its original capacity. So after 1,000 cycles, you should still have 50–60 percent of the battery capacity remaining, and 30–40 percent after 1500 cycles, etc.

iPhone Battery 

Apple is using lithium-ion batteries as an iPhone battery. Compared to traditional battery technology, lithium-ion batteries charge faster, last longer, and have a higher power density for longer battery life in a smaller box. When you know a little bit about how they’re operating, they can work a lot better for you.

Meanwhile, Apple’s lithium-ion battery uses fast charging to quickly reach 80 percent of its power and then turns to slower charging. The amount of time it takes to hit the first 80 percent can vary depending on your settings and which system you’re paying for. The combined cycle not only helps you get out of here but also increases the life of your battery.

Why Does your iPhone Battery Health Decline?

It’s important to understand the factors contributing to the rapid reduction in your iPhone’s battery health. Here are some of the most common reasons:

• Excessive Usage: If you’re constantly using your phone for streaming, gaming, browsing, and downloading large files, it puts a strain on the battery, causing it to deplete quickly.
• Apps Running in the Background: Leaving apps running in the background, especially those that track your location, consumes power even when not in use. This can significantly reduce your battery life.
• Exposure to Heat: High temperatures can harm the battery, leading to faster deterioration.
• Failure to update iOS: Not keeping your iPhone’s iOS updated can impact battery health, as updates often include optimizations for better performance.
• Use of Non-Apple Accessories: Using third-party battery cases or chargers may damage the battery and degrade its overall health over time.
• Battery Age: Batteries have a limited lifespan, and as they age, they naturally lose some of their capacity

How to Maintain Your iPhone’s Battery Healthy

Now, this is the general question that every iPhone users ask themselves that how to maintain 100% iPhone battery health in case of purchasing a brand new and expensive iPhone like iPhone 15 Pro Max, 15 Pro, 15, and some other models. Don’t worry! Here, I will provide 10 absolutely vital tips to maintain 100% iPhone battery health.

iPhone Battery Health: 10 Tips to Maintain Your iPhone’s Battery Healthy

Here are our 10 absolutely vital tips to maintain 100% iPhone battery health.

Tip #1. Enable Low Power Mode

Low Power Mode reduces the overall power requirement and lets your battery last longer. Apple claims that the mode will allow you to gain three extra hours of battery life from your iPhone. Low Power Mode is not the default option that happens automatically in the background.

It will be provided automatically when you enter the remaining 20% power: you will see a warning flash and the option to switch on Low Power Mode. Do this, and you’ll find that the battery indicator turns orange rather than red (or green would be if you had enough power). The mode will be turned off automatically again when you charge past 80 percent.

Low Power Mode can reduce power consumption by stopping Mail fetch, Hey Siri, background refresh applications, automatic updates, and some visual effects. Actually, all of these features have already been switched off on our iPhone, but Low Power Mode still seems to have an impact.

To Enable Low Power Mode:

• Settings > Battery.
• Turn on Low Power Mode.

Tip #2. Enable Optimized Battery Charging Option on iOS 13 or Later

Now, a new feature in the current iOS 13 that is owned by default under battery health is another thing you should consider doing to preserve and maintain good battery health on your iPhone and that is called “Optimized Battery Charging”. If you have this feature on, keep it going because it also allows the system to preserve its battery health. What it does, it will charge up to 80 percent of your iPhone until you’re able to use it again, and then that remaining 20 percent will continue to charge just until you pick it up in the morning.

To Enable Optimized Battery Charging:

With iPhone 14 models and earlier

• Settings > Battery.
• Battery Health.
• Turn on Optimized Battery Charging.

With iPhone 15 models

• Settings > Battery.
• Battery Health & Charging.
• Charging Optimization and choose an option.

Tip #3. Use Dark Mode

Dark Mode is a new feature that comes in iOS 13. One benefit of the mode is that it can make your screen more pleasant to see, and less pressure on your eyes if you look at it in a darkened room (like you might at night). Another benefit is that by switching off the colors on your iPhone, you will need less power to light up the display, so it’s a good idea to turn on Dark Mode.

To Enable Dark Mode:

• Settings > Display & Brightness.
• Choose Dark.

Tip #4. Set Auto-Lock as Low as Possible 

To Set Auto-Lock:

• Settings > Display & Brightness.
• Auto-Lock.
• Set your device to sleep after 30 seconds of inactivity.

Set Auto-Lock as Low as Possible 

Tip #5. Enable Auto-Brightness

Another tip to maintain good iPhone battery health is to turn down the brightness or enable Auto-Brightness. It takes a lot of energy to light up the pixels on your device’s Retina display. In reality, the single biggest iPhone and iPad battery killer we found in testing was excessive screen brightness. A few years ago, we found that an iPhone 5 lasted 6 hours, 21 minutes while watching 720p video at full brightness. The same phone lasted 9 hours, 48 minutes when we changed the screen to have a brightness. That is a gigantic difference.

To Enable Auto-Brightness:

• Settings > Accessibility.
• Display & Text Size.
• Turn the Auto-Brightness on.

Enable Auto-Brightness

Tip #6. Use Original Charger

One of the most important and useful tips to maintain 100% iPhone battery health is to use the original chargers and accessories. Always use the iPhone’s original charger, otherwise, you could be causing damage to the iPhone’s battery by using cheap chargers. Meanwhile, These Apple chargers are specifically tailored to charge your devices, and they have all the technology required to give you the most optimal charging conditions and stability for charging of your devices.

Tip #7. Protect Your iPhone From Overheating

Most people will leave their iPhones in their dash, in their cars, or on the beach. We sit down in direct sunlight, and we leave them out. This really affects the battery life and, when you hold it under a warmer setting, it won’t sustain its charge in the long run. All you need to do is always try to cover your phone under direct sunlight if you’re at the beach and avoid leaving, particularly in-car dash, etc. So, avoid long-term high temperatures, directly reaching your iPhone. If your iPhone hits the sun, that will kill the battery. That’s something you certainly want to keep in mind too.

Tip #8. Don’t Charge Your iPhone All the Way to 100%

Older battery types had a’ battery memory.’ If you haven’t charged them maximum and discharged them to zero tanks, they’ve’ remembered’ and limited their range of use. It was safer for their longevity if you were still exhausted and completely charging the battery.

Meanwhile, Newer phone batteries work differently. It stresses the battery to drain it completely or charge it completely. Phone batteries are happiest if you keep them above 20% capacity and below 90%. To be extremely precise, they’re happiest around 50% capacity.

Tip #9. Update iOS

The last tip to maintain 100% iPhone battery health is to regularly update your iOS. Updating to the latest version of iOS is usually an all-purpose remedy when you’re having minor problems with an iPad or iPhone; Apple uses its daily (free) operating system updates to carry out flaw, bug, and glitch fixes, and it’s entirely possible that a problem you’re experiencing can be resolved with a quick upgrade to your OS. That involves issues with the batteries.

Update iOS

Tip #10: Use MagSafe Wireless Charger For Overnight Charging

The habit of charging our phones overnight is quite common and hard to break. Many people do it every night. Advising against overnight charging doesn’t always resonate because it’s a deeply ingrained routine. If you find it difficult to give up this habit, consider using a certified Apple MagSafe wireless charger.

Wireless chargers typically operate at a slower pace than wired chargers. They employ a coil of wires to generate electromagnetic fields. In contrast, wired chargers have small transformers that produce charging power. Consequently, charging with a wireless charger tends to generate less heat compared to wired chargers.

Use MagSafe Wireless Charger For Overnight Charging

That’s it. This post was about how to maintain 100% iPhone battery health, and I have provided 10 extremely useful tips to keep your iPhone’s battery healthy and last longer. Keep in mind that the batteries degrade over time, so you can see the percentage of the battery or the power falling over the years, which is going to be considered natural. But if you follow these simple tips, you’ll get a lot better on your iPhone battery life.
