11 Battery and Charging Tips for iPhone 17 Series

Below are the 11 best battery and charging tips, with step-by-step instructions to apply them. These hacks work across all iPhone 17 models and are designed to save power, speed up charging, and keep your battery healthy for years.

1. Check Battery Health at Setup

Checking your battery’s health right after setting up your iPhone ensures it starts in top condition. A new phone should show 100% capacity and zero charge cycles.

• How to do it: Go to Settings > Battery > Battery Health. Look at the “Maximum Capacity” percentage; it should be 100%. Check “Cycle Count” to confirm it’s at zero. If either shows wear, contact Apple Support to verify your device is new.
• Why it helps: Confirming a fresh battery means you’re starting with the best possible performance, especially important for the 5,088 mAh battery in the iPhone 17 Pro Max, which delivers 39 hours of video playback.

2. Enable Adaptive Power Mode

Adaptive power mode is a smart setting that learns how you use your phone and adjusts background tasks to save energy.

• How to do it: Navigate to Settings > Battery > Power Mode. Toggle on “Adaptive Power Mode.” Use your phone normally for a week, and it will optimize app activity based on your habits, like limiting notifications or updates when you don’t need them.
• Why it helps: This hack can extend battery life by 15-20% by reducing unnecessary processes, especially during heavy use like gaming or streaming.

3. Get Adaptive Power Notifications

This setting alerts you when adaptive power mode activates, so you know when your phone is saving energy.

• How to do it: In Settings > Battery > Power Mode, turn on “Adaptive Power Notifications.” You’ll get a pop-up when the mode kicks in, like when the battery drops below 20%.
• Why it helps: Knowing when the phone adjusts power usage helps you plan tasks, ensuring you don’t run out of charge during critical moments.

4. Use Low Power Mode for Emergencies

Low power mode cuts down on non-essential features to stretch your battery when it’s running low.

• How to do it: Go to Settings > Battery and toggle on “Low Power Mode.” Alternatively, swipe down from the top-right corner to open Control Center, tap the battery icon, and turn it on. It reduces animations, background app refresh, and more.
• Why it helps: This can add hours of use when you’re below 10%, perfect for getting through a long day without a charger.

5. Optimize Battery Charging for Long-Term Health

Optimized charging prevents overcharging by holding the battery at 80% overnight and completing the charge just before you wake up.

• How to do it: In Settings > Battery > Battery Health, enable “Optimized Battery Charging.” The phone learns your charging routine after a few days and adjusts automatically.
• Why it helps: Keeping the battery at 80% most of the time reduces wear, helping the iPhone 17 Pro Max’s 5,088 mAh battery maintain capacity longer.

6. Turn Off Background App Refresh

Background app refresh lets apps update content even when you’re not using them, which drains the battery.

• How to do it: Go to Settings > General > Background App Refresh. Set it to “Off” to stop all apps, or choose “Wi-Fi” to allow updates only on Wi-Fi, which uses less power than cellular data.
• Why it helps: Disabling this for apps like social media or news can save significant battery, especially on the iPhone 17 and 17 Air with slightly smaller batteries.

7. Switch to LTE in Weak 5G Areas

5G can drain the battery faster, especially in areas with poor signal where the phone constantly searches for a connection.

• How to do it: Go to Settings > Cellular > Cellular Data Options > Voice & Data. Select “LTE” instead of “5G On” or “5G Auto.” Test by checking signal bars in a low-coverage area.
• Why it helps: LTE uses less power than 5G, adding hours of battery life in areas with spotty 5G, which all iPhone 17 models support.

8. Disable Always-On Display

The always-on display keeps the screen active to show time and notifications, but it uses extra power.

• How to do it: Navigate to Settings > Display & Brightness > Always On Display. Toggle it off. You can still check the time by tapping the screen.
• Why it helps: Turning this off can save up to 10% battery daily, especially useful for the iPhone 17 and 17 Air, which have less battery capacity than the Pro Max.

9. Use a 40W Charger for Fast Charging

The iPhone 17 series supports 40W fast charging, reaching 50% in about 20 minutes, a big improvement over older models.

• How to do it: Purchase a 40W USB-C charger (Apple or third-party, like Anker). Plug it into your iPhone with a USB-C cable. Charge from 0% and check the time to hit 50%.
• Why it helps: This hack gets you back to using your phone quickly, ideal for busy schedules or when you’re traveling with limited plug time.

10. Enable 25W Wireless Charging with MagSafe

All iPhone 17 models support 25W wireless charging with MagSafe and Qi 2.2 chargers, faster than previous generations.

• How to do it: Get a MagSafe charger or Qi 2.2-compatible power bank (like ESR’s Cryoboost). Place the phone on the charger, ensuring it aligns with the magnets. Test by charging for 30 minutes to see the percentage increase.
• Why it helps: Wireless charging is convenient for desks or cars, and 25W speeds up the process compared to older 15W chargers, keeping your phone ready.

11. Convert to eSIM for Battery Efficiency

The iPhone 17 series is eSIM-only worldwide, removing the physical SIM tray to make space for a larger battery, especially in the Pro Max.

• How to do it: Go to Settings > Cellular > Add eSIM. Follow your carrier’s instructions to transfer your plan or scan a QR code. If upgrading, transfer the eSIM from your old phone during setup.
• Why it helps: The eSIM design allows for a bigger battery, contributing to the 39-hour video playback on the Pro Max, and ensures you’re using the most efficient setup.

Why Battery Management Matters

Battery life is critical for getting through a busy day, whether you’re streaming videos, playing games, or using the advanced cameras on the iPhone 17 series.

The Pro Max’s 5,088 mAh battery offers 39 hours of video playback, a 15-20% improvement over the iPhone 16 Pro Max’s 4,685 mAh for 33 hours. The base iPhone 17 and 17 Air have smaller batteries but still last over a day with moderate use.

These tips ensure you maximize that capacity, avoid unexpected shutdowns, and keep your phone healthy for years. Fast charging and wireless options also mean less time plugged in, so you can stay on the go.

• Lower Screen Brightness Manually: Go to Settings > Display & Brightness and slide the brightness bar down. Or, swipe down to Control Center and adjust the slider. Lower brightness saves power, especially indoors where 3000 nits isn’t needed.
• Turn Off Location Services for Non-Essential Apps: In Settings > Privacy > Location Services, set apps like social media to “Never” or “While Using.” This stops constant GPS tracking, which drains the battery.
• Limit Notifications: Go to Settings > Notifications and turn off alerts for apps you don’t need, like games or news. Fewer notifications mean less screen wake-ups, saving power.
• Disable Haptic Feedback for Keyboard: In Settings > Sounds & Haptics > Keyboard Feedback, turn off Haptic. Vibrations use small amounts of battery, and disabling them adds up over time.
• Schedule Do Not Disturb: In Settings > Focus > Do Not Disturb, set a schedule for nighttime. This stops notifications from lighting up the screen, preserving battery during sleep hours.

These extra hacks work well with the main tips, especially for heavy users who need every bit of battery life. For example, combining low power mode with disabled background refresh can make the iPhone 17 Air last through a full day of calls, texts, and browsing without needing a charge.
