How to Extend iPhone Battery Life
It’s something every iPhone user can relate to: watching your battery life drop faster than you'd like, especially when you're out and about. Whether you're navigating the lively streets of Toronto or capturing the awe-inspiring northern lights near Whitehorse, your iPhone is always there, a lifeline for staying connected and productive. But as time goes on, the battery naturally starts to lose some of its power. Keeping it in top shape is key to making sure your phone stays ready when you need it most. In this guide, we’ll cover everything from reading your battery data to adopting healthy charging habits, as well as tips on accessories that can help extend your iPhone’s battery life and performance.
How to Check and Read iPhone Battery Data
Understanding how your iPhone uses power is the first step in extending its battery life. Apple makes it easy by providing built in tools that allow you to track battery consumption, spot any issues, and keep tabs on long term health.
1. Accessing the Battery Menu in Settings
Start by heading over to Settings > Battery. This is your go to spot for all things power related. You’ll immediately see an overview of your battery’s usage, showing you where your energy is going throughout the day.
2. Reading the 24-Hour and 10-Day Charts
The charts in the Battery menu offer a clear picture of your usage patterns. The 24-Hour Chart breaks down your activity hour by hour. You can spot spikes in usage or periods where your phone wasn’t in use. If you notice a sharp drop in battery level when your screen is off, it could mean an app is running in the background unnecessarily, maybe that news app or social media feed refreshing itself even when you're at home in Winnipeg.
The 10-Day Chart gives you a broader view of trends over time. This is useful for spotting things like an increase in battery usage after installing a new app or a major iOS update.
3. Checking Battery Usage by App
Scroll down in the Battery menu, and you’ll find a detailed breakdown of which apps are using the most power. This is one of the most useful features for optimizing your battery life. Suppose you see an app you rarely use taking up a large chunk of your battery, like a weather app constantly refreshing in the background (even when you're nestled inside a cabin in the Canadian Rockies or relaxing at home in Calgary), it’s a good indication that you need to adjust its settings. For apps like this, try limiting their background activity or disabling location services. This can significantly reduce their impact on your battery, helping you make the most of each charge. It’s a simple step that can help stretch your battery life throughout the day.
4. Viewing Battery Health and Capacity
This is one of the most important areas to check. Tap on Battery Health & Charging and look for Maximum Capacity, which shows how much of your battery’s original power it can still hold. As the percentage drops over time, so does the amount of time your iPhone can run between charges. For example, if your battery health is sitting around 85%, you’ll likely notice it doesn’t last nearly as long as it did when it was brand new. If your phone battery is draining so fast, keeping an eye on this metric helps you understand your phone’s overall health and decide when it might be time to adjust your habits or plan for a battery replacement down the road.
Common Factors Affecting Battery Health
Much like keeping your car running smoothly for long road trips across the Trans-Canada Highway, your iPhone’s battery needs attention to stay in good shape. Several factors, both environmental and how you use your phone, can affect its health. Here's what to keep in mind:
1. Heat and Temperature Stress
Extreme temperatures are the biggest threat to lithium-ion batteries.
Heat: Charging your iPhone on a hot summer day or leaving it on your dashboard during a road trip through places like Ontario or British Columbia can cause permanent damage to the battery. It overheats and degrades quicker, which shortens its lifespan.
Cold: While cold weather doesn’t cause long-term damage, using your iPhone in the bitter cold of a Saskatchewan winter might cause your battery to drain faster or struggle to hold a charge temporarily. If you're out in the cold for long periods, you might notice your phone performing slower than usual.
2. Charging Cycles and Usage Patterns
A battery cycle happens when you use an amount of battery that totals 100%, it doesn’t need to be from one single charge. The more cycles your battery goes through, the shorter its life. The number one tip would be to try not to let your battery drop to 0% too often and then charge all the way to 100%. Keeping your battery level between 20-80% is the sweet spot and helps extend its lifespan.
3. High-Performance Workloads and Background Activity
Intensive tasks like playing demanding 3D games, editing 4K videos, or using apps that constantly fetch data in the background put a heavy load on your iPhone’s battery, generating heat and increasing wear. To help prevent iPhone overheating and unnecessary strain on your battery, it’s important to regularly review your Background App Refresh settings. Apps that are constantly updating or syncing in the background can consume more power than you might expect, so limiting this activity for apps you don't use often can go a long way in extending your battery life.
4. Power Delivery Quality and Cable/Charger Issues
Using uncertified or generic charging cables and adapters can cause inefficient power delivery, leading to overheating and inconsistent voltage, which can damage your iPhone's battery over time. While it might be tempting to save a few bucks on cheap cables, opting for low quality accessories can cause long-term harm. Always choose MFi-certified cables and chargers from trusted brands to ensure steady, reliable power flow and to protect your battery from unnecessary wear.
5. Software Updates and System Processes
After a major iOS update, you might notice a temporary drop in battery life as the system re-indexes files and optimizes various features. This can cause a brief spike in power consumption while your iPhone adjusts to the new update. If you find your battery draining faster than usual right after an update, don’t worry, give your iPhone a few days to settle in, and the battery performance should return to normal as the system finishes its background tasks.
Healthy Charging Habits for iPhone Battery Life
Adopting a few easy charging habits is the best way to keep your iPhone’s battery healthy and make sure it lasts as long as possible. These simple steps will help reduce wear and keep your phone running smoothly.
1. Maintain a 20–80% Daily Charge
The ideal range for lithium-ion batteries, like the one in your iPhone, is between 20% and 80%. Keeping your charge in this zone regularly helps reduce stress on the battery and slows down wear. You can think of it like driving a car at a steady speed, not too fast, not too slow, it helps everything run smoothly. Staying within this range can significantly extend your battery’s lifespan over time.
2. Avoid Heat During Charging
If your iPhone gets too warm while charging, it’s a good idea to remove the case, move it to a cooler spot, or pause charging until it cools down. Heat is one of the biggest factors that can damage your battery over time, so keeping your phone cool while charging is key to maintaining its health.
3. Use Certified Chargers Only
Always make sure to use MFi-certified cables and trusted charging bricks. These certified accessories ensure stable power delivery, protect against voltage spikes, and help prevent damage to your iPhone’s battery over time. Using cheap, unbranded chargers might seem like a quick fix, but it can lead to long-term issues. Additionally, when charging on the go, consider choosing the right power bank for iPhone charging. A high-quality certified power bank ensures efficient and safe charging, keeping your battery healthy in the long run.
4. Limit Fast Charging Usage
Fast charging is super convenient, but it generates more heat, which can put extra strain on your battery. It’s best to use fast charging only when you really need it. For everyday use, sticking with a standard charger is gentler on your battery and will help it last longer in the long run.
5. Avoid Overnight Charging
Leaving your iPhone plugged in overnight at 100% keeps it under constant high-voltage stress, which can wear down the battery over time. Instead, make use of the Optimized Battery Charging feature, found in Battery Health & Charging. This feature learns your daily routine and delays charging past 80% until just before you wake up, so your phone stays in a healthier charging range overnight.
