How to extend iPhone battery health and use for many years

Not everyone upgrades to a new iPhone every year. Your current iPhone should probably be Good for three or four years, thanks to Apple subsidizing each model for up to five years of iOS updates. However, its battery is a consumable component that deteriorates over time, and if its power drops too low, you won't be able to use your iPhone comfortably.To help, here are 11 tips that will extend your iPhone's battery life. This will ensure that you get good usage time per charge for many years.

1.Don't turn off Optimized Battery Charging

Overcharging the battery is not good. Optimized Battery Charging learns from your daily charging routine and uses artificial intelligence to understand your charging patterns. With that, it holds the charge and waits to charge past 80% until you need to use your iPhone.

For example, suppose you go to bed at 10 pm each day and wake up at 6 am. Before going to bed, plug in your iPhone every night at 10pm to charge it. Now, your iPhone will usually charge up to 80%, and after that, it won't charge.

Then, around 4 or 5 AM, your iPhone will automatically resume charging and go to 100% before you wake up at 6 AM.

Optimized Battery Charging is turned on by default on iPhone.

  • You can access it from the Settings app > Battery > Battery health & charging. From here, make sure not to turn it off.

2. Take precautions not to overheat your iPhone

Heat, water and dust are the biggest enemies of any electronic device. The iPhone's lithium-ion battery is no exception.Excess heat can negatively affect it and cause its lifespan to be greatly reduced if you often overheat your iPhone.

So,during daily use, make sure that your iPhone does not get too hot.You can control this by removing the case, refraining from using a lot of intensive apps for extended periods, not leaving the iPhone in a locked car on a sunny day, etc.

3. Avoid charging to 100% and discharging completely

Charging the battery to both ends is not good for its health. So, to increase the lifespan of your iPhone battery, try not to fully charge it up to 100% and discharge it from 0 to 5%.

Important: Don't overthink this. Keep in mind the above fact but charge your iPhone as you normally would at your convenience. If you ask me, I often charge my iPhone up to 80% or 90% and plug it back in when the battery gets down to about 30%.


4. Don't leave your iPhone plugged in for hours or overnight

Optimized battery charging helps address the overcharging issue. However, it is best to take precautions and not leave your phone connected to charging for several hours or overnight.

5. Use wired charging instead of wireless charging

Wireless charging could be convenient. However, it may generate a lot of heat which can affect your iPhone battery.So try using wired charging instead of wireless charging or MagSafe alternatives.

6. Fast charging only when needed

With fast charging, the battery is forced to consume a large amount of energy in a short period. This is great for quick charges but not good for the long-term health of the battery.I have a 61W MacBook charger that can quickly charge an iPhone.I use this on rare occasions.For everyday use, I use Apple's 10W adapter (or sometimes a 20W iPad adapter) which slowly fills the iPhone battery, keeping the battery healthy.

7. Use Apple or MFi-certified chargers and cables

Almost all adapters can charge your iPhone, and since Apple doesn't provide a charger in the box, you might be tempted to opt for a cheaper option.However, for best results, use an Apple adapter or an MFi-certified adapter. Chargers from other reputable manufacturers like Samsung must pass all safety checks and may not harm your iPhone. But note the wattage of the charger before using it with your iPhone.In addition, also limit yourself to using an Apple or MFi certified Lightning cable.

8. Disable features that you are not using

Another tip to extend the life of your iPhone is to reduce the load on it. And one of the best ways to do that is to disable some iPhone features that you may not need.This includes things like turning off background app refresh, disabling automatic updates, enabling auto-brightness, setting cellular settings for Auto 5G, and so on.

9. Restart your iPhone regularly

To keep your iPhone in perfect condition, you should make it a habit to turn it off and on regularly. This will fix a lot of minor issues and keep your device fast and responsive.

10. Keep your iPhone updated

Apple introduces new improvements with software updates. Sometimes, unnecessary battery drain and other similar issues can be fixed by iOS updates. So, for best results, keep your device updated by going to Settings > General > Software Update.

NOTE: Your iPhone can download, prepare, and install iOS update if its battery is more than 50%. However, software updates put a lot of pressure on the battery, hence it is best to perform the update with your iPhone plugged in to charge.


11. Planning not to use the iPhone for a long time? Store it at a cost of 50%

Finally, if you have two devices or if you regularly switch to Android, you can keep one of your iPhones stored in the drawer. In doing so, be sure to charge the iPhone battery to around 50% before storing it for a long time. Do not store it fully charged or completely empty.


iPhone battery health

The above tips will help increase the health of your iPhone battery and ensure that you can use the device for a few years without noticeable battery issues.

However, no matter what you do, slowly, the iPhone battery and all other batteries like those in AirPods, Apple Watch, Apple Pencil, iPad, etc. degrade. This cannot be stopped. But the above tips will help.

Finally, you can see your iPhone's battery health from Settings > Battery > Battery Health & Charging. From here, note the ratio next to Maximum Capacity.

If it is dangerously low, you will see a message asking you to service the battery.
