Is your iPhone battery draining faster than it used to?
Whether you’re a long-time iPhone user or just switched from another phone, knowing how to keep the iPhone battery healthy is essential for maintaining performance and ensuring your device lasts for years. iPhones use lithium-ion batteries, which naturally degrade over time. The good news is, with a few simple habits, you can slow this process and extend your battery’s lifespan.
Today, we’ll also cover the best way to keep iPhone battery healthy so you can enjoy reliable power every day.

Let’s get started!
Why Battery Health Matters for iPhone Users
Every charge and discharge slightly reduces your iPhone’s battery capacity. Over time, this can lead to shorter battery life, slower performance, and more frequent charging. Many users notice their battery health dropping to 72–80% after several years.
When a battery loses capacity, the phone may heat up more, require extra charging, and sometimes perform slower. Apple recommends replacing your iPhone battery when Battery Health drops below 80% or when you experience issues like reduced backup, overheating, or sluggish performance. Following the right habits can slow this natural decline and help your iPhone perform optimally for years.
How to Keep the iPhone Battery Healthy: Long-Term Care Tips
1. Charge Between 20% and 80%
One of the most important steps is to avoid extreme charge levels. Regularly letting your iPhone drain to 0% or charging to 100% can accelerate battery degradation. Keeping it between 20% and 80% reduces strain and prolongs the battery’s chemical life.
Why this matters: Lithium-ion batteries have a limited number of full charge cycles. By staying in the 20–80% range, you reduce the total number of full cycles, helping your battery last longer.
2. Enable Optimized Battery Charging
Apple’s Optimized Battery Charging feature is designed to preserve battery health. It slows charging at 80% and completes it just before you need to use your iPhone, such as overnight before you wake up.
To enable it:
- Go to Settings > Battery > Battery Health & Charging
-
Toggle on Optimized Battery Charging
This is widely regarded as the best way to keep iPhone battery healthy without changing your daily routine.
3. Avoid Excessive Heat
Heat is a major enemy of battery health. Charging while playing heavy games, using video apps, or leaving your phone in a hot car can accelerate wear. Keep your iPhone in cool environments and remove thick cases if it heats up during charging. Ideal temperature for use and charging is around 68°F (20°C).
4. Use the Right Charger
Always use the charger that came with your iPhone or a reputable third-party charger that meets Apple’s specifications. Low-quality or inconsistent chargers can damage the battery over time.
5. Don’t Overuse Fast Charging
Fast charging is convenient but generates more heat, which can strain the battery. Use it when necessary, but for everyday charging, stick to the standard speed. Over time, this helps maintain better battery health.
6. Avoid Using iPhone While Charging
Running power-hungry apps while charging can generate heat and stress your battery. If possible, charge your iPhone before heavy usage or avoid intensive apps during charging sessions.
7. Store Properly When Not in Use
If you’re storing your iPhone for more than a month, charge it to around 50% and power it down. Storing it fully charged or completely drained can lead to long-term damage.
8. Battery Replacement When Necessary
Even with perfect care, batteries degrade over time. Apple recommends replacement once battery health falls below 80% or if performance becomes an issue. Most iPhone users find battery replacement necessary after 3–5 years of regular use.
Best Way to Keep iPhone Battery Healthy: Daily Use Tips
- Enable Low Power Mode: Reduces background activity when battery is low.
- Reduce Screen Brightness: Use Auto-Brightness to save energy.
- Limit High-Drain Apps: Games, video apps, and social media can heat your phone and drain battery quickly.
- Keep Software Updated: iOS updates often improve battery performance.
- Disable Unnecessary Features: Keyboard vibrations, haptic feedback, Bluetooth, or GPS when not needed.
- Use Wi-Fi Instead of Mobile Data: Wi-Fi consumes less power.
- Airplane Mode in Poor Signal Areas: Helps conserve energy when your iPhone struggles to connect.
- Keep Your iPhone Cool: Avoid direct sunlight or hot environments.
Forum experiences show that even small habits like these, combined with optimized charging, can help users maintain 90%+ battery health after a year of regular use.
Frequently Asked Questions
What is the 20/80 battery rule for iPhone?
To preserve your iPhone’s battery health, it’s recommended to charge it when the battery drops to around 20% and unplug it before it reaches 80%. Avoid letting the battery fully drain to 0% or charging it to 100% all the time, as these extremes accelerate battery wear. Following this habit helps maintain capacity and extends the battery’s overall lifespan.
Is 70% iPhone battery health good?
A battery health of 70% indicates significant degradation and is considered poor. At this level, your iPhone may shut down unexpectedly, run slower, and require frequent charging. Apple suggests replacing the battery once health drops below 80% to restore performance and reliability.
Is it better to set iPhone battery at 90% or 100%?
For long-term battery preservation, limiting your iPhone’s charge to around 90% (or 80%) is better than fully charging to 100%. Fully charged or fully drained lithium-ion batteries degrade faster over time. Using “Optimized Battery Charging” in iOS is ideal, as it keeps the charge around 80% until you need it, and newer models like iPhone 15+ allow a set “Charge Limit” to maintain a healthy cap.
So, How to Keep the iPhone Battery Healthy
Your iPhone battery powers your daily life, and caring for it properly ensures reliable performance for years. By adopting simple habits, you can slow natural battery wear, maintain longer-lasting charges, and keep your device running smoothly. Even small changes, like avoiding heat and using optimized charging, add up over time.
Key Takeaways:
- Charge between 20% and 80% to reduce strain on your battery and extend its lifespan.
- Enable Optimized Battery Charging for automatic protection during overnight or extended charging sessions.
- Avoid excessive heat by keeping your iPhone out of direct sunlight, removing thick cases while charging, and not running heavy apps simultaneously.
- Use the right charger; Apple-certified or reputable third-party chargers prevent inconsistent power delivery.
- Limit fast charging and intensive app use during charging to reduce battery stress.
- Monitor battery health regularly and consider replacement if capacity drops below 80%.
- Adopt daily energy-saving habits: Low Power Mode, Wi-Fi over mobile data, lower screen brightness, and limiting high-drain apps.
By following these steps, your iPhone battery can stay healthier for longer, giving you reliable power every day without unnecessary worry.
