11 Common Signs which Show that You need to Replace an iPhone Battery

Getting a new battery for your iPhone is ideal. But before that, some aspects should guide you in making a choice. Here’s what to show your iPhone needs a new battery.

1. An Oversized Battery

It is the most direct sign to show you that your battery is gone. If the battery still serves your phone, it will harm your charging system.

Please think about replacing the battery once you notice a change in the size. Besides harming your system, the battery can break the case.

So, you’ll have to spend more to maintain your battery. Your screen will have a hazy white screen if the battery swells.

The phone’s body and the screen will move away for some inches. It’s because the increase in size affects more elements in your phone.

2. Fast Battery Drain

Besides the battery size, a draining battery scares most iPhone users. The battery ions can’t hold more power because they are weak.

Each iPhone has a time that it can last regardless of how you use it. If it’s iPhone 6 and above, it should hold power for 6 to 8 hours after a full charge.

Anything less than that shows your battery life is going down. It can be that your battery’s life has ended or has many faults.

3. Sluggish iPhone

Sometimes, if your phone battery is weak, your device won’t function fast. iPhones have unique features that need a lot of power.

So, if the battery is weak, the iPhone will lag while handling most tasks. Giving your iPhone a new battery will be a fantastic boost.

It happens on old iPhones with newer iOS. You can check your iPhone’s battery health to confirm if you need a new battery.

4. You Get Power after you Plug a Dead iPhone

iPhones have a unique way of charging once the charge is over. On a regular iPhone, it will take one or two minutes to power up after the battery dies and you plug it in.

It takes two minutes for the battery to refresh. But sometimes, you plug it in and immediately see the Apple logo. Expect the battery to start at 5%.

Your iPhone will show that your battery is at its best level. So, it is time to get a new one.

5. High Heat Levels on the Phone

Any extreme heat levels are never friendly to your battery. When you use your iPhone even in average temperatures, and it becomes hot, it is time to get a new battery.

Every Li-Ion battery in modern phones can protect your phone from inner heat. Remember, you’ll feel the heat even when using a light phone app.

It will be worse if you open many apps and connect them to the charger or the sun. Your iPhone can even go off.

If you ignore such a sign, your phone will be at risk. The heat will damage various parts of your iPhone, including the people’s favorite, the camera.

6. Aging Battery

Even if you keep your iPhone battery well, it keeps aging off. Apple indicates that iPhone batteries should last for at least two years.

If you use an old battery, it is not strange for your iPhone to have poor performance. So, you should consider replacing the item. It saves you from the trouble of recharging every time.

Also, as the tech world grows, Apple keeps releasing new iOS versions and aspects. It’s these features that throttle most iPhones.

Replacing the battery will help you. If you get a genuine one, it will have a more excellent range to hold the power needs of these features.

7. The Phone only works when Charging

If you only use your iPhone when you plug it in, your battery is gone. The lithium ions can’t hold power anymore.

Your iPhone will have this problem if you have the wrong usage and charging habits. It could be that you use your iPhone every moment while it’s charging.

Also, you may be using a fake cable. Such behaviors weaken that battery and kill it fast.

You can confirm this problem by charging your device for a few minutes. After that, take the plug; if the power goes off, it will ensure your fears.

8. The iPhone won’t Charge

As for this sign, ensure you use the genuine iPhone cable. The battery won’t be able to take up any charge, especially if the battery is empty.

If the charger works fine on other iPhones, your battery and charging system might have some issues. Your iPhone might be a bit new or old.

The iPhone can charge once again. However, the problem can also be with your charging port. Ensure you go for a new battery.

9. The Error Message

Various iOS versions are smart to protect multiple parts of the phone. Sometimes you can see the message “Your iPhone battery may need to be serviced.”

It means your battery isn’t in proper shape. Remember, this message comes on iOS 10.2.1 and up to iOS 11.2.6.

Don’t ignore this message. Consider getting a new battery, and you won’t see the message. The system would have seen a danger beyond your eyes.

10. The iPhone won’t Turn On

Like any other electronic device, your iPhone will never turn on if the battery is weak. It’s among the most excellent ways to confirm that your battery is dead.

As you start your iPhone, it will need a lot of power. But if your battery is weak or dead, it won’t start up your phone. Such an act will occur when the battery is half full or low.

Sometimes, it will turn on, but the screen will remain black. You’ll receive notifications and other signs that the power is on.

Try using another or the original charger to confirm your battery is weak. If the iPhone is fragile, the ions won’t have much charge to power the phone’s display.

11. The Phone Shuts Down Most Times

Your iPhone’s battery will be weak when it keeps shutting down. The act will happen when your battery power is half full, full, or empty.

It shows that the ions have died or are too weak to hold power. Expect your iPhone to behave this way, especially when using any aspect that needs more power.

Wi-Fi, location, and push emails use a vast amount of power. A dead battery will not have the voltage range to carry out these actions.

The phone stops draining much power when it is off. So, the weak battery can now refresh as you plug it into the charger.
