You may need to fix your iPhone battery for different reasons. It could be due to a minor issue or something more serious. In any case, a faulty battery reduces the lifespan and efficiency of your iPhone.

Generally, when confronted with battery issues, the ideal solution is to search for phone repair services online. Alternatively, you may want to go here and look for local technicians near you. But, when both of these options are far-fetched, here are simple ways to check and handle the different iPhone battery problems:

1. Fast Drainage

If your iPhone’s battery dies so fast, it’s an issue that needs to be resolved quickly.

iPhone batteries can drain fast for a couple of reasons. One of such is having your mail set to push. When your iPhone is set to ‘push,’ it’ll maintain a constant connection with your email, such that you’ll receive every new mail as it arrives. This continuous flow causes your battery to drain quickly. 

To fix this, switch your mail’s settings from ‘push’ to ‘fetch.’ This way, your iPhone will receive mail intermittently, not all the time. This will help preserve its battery life. 

2. Overheating While Charging

If your iPhone gets extremely hot while charging, it’s a sign of a battery problem. iPhone overheating can damage the battery in the long run. While it’s normal for devices to get a bit hot when being charged, you shouldn’t neglect your iPhone when it begins to generate intense heat. 

An excellent way to start fixing this problem is to stop charging the phone and allow it to cool off. You can also turn it off and then restart after some time. This would give the phone some time to let out some heat. 

Aside from charging, using your phone as a hotspot can increase its heat while charging. If your hotspot is on, ensure you turn it off. 

3. iPhone Not Turning On Despite Being Charged

If your phone goes off and doesn’t turn on, you don’t have to lose hope. When an iPhone battery is completely drained, it takes about 15 minutes of charging for it to boost. Sometimes, it takes as long as an hour. 

When this happens, allow the phone to continue to charge for about an hour. If that doesn’t fix the issue, you can perform a hard reset, wherein you hold down the power and home buttons simultaneously for about 15 seconds. If this still doesn’t work, you can restore its factory settings. However, you should back up your data so you don’t lose it during the reset.

4. Sudden Shutdown When It Still Has Some Charge

When your iPhone shuts down even when it has enough charge, check its date and time settings, and turn on the ‘set automatically’ option. This will prevent it from going off unexpectedly. 

Another way to do this is calibrating the battery by allowing it to drain off totally. When it’s drained, your phone will automatically go off. Then, you can get it charged. Even when the phone charges 100%, you should leave it charging for an extra 60-90 minutes. This will help resolve the issue and extend the battery’s life. 

5. Slow Charging

Two factors can make an iPhone charge slowly. The first is an issue relating to hardware, while the other involves the charging cable. When you observe your iPhone is charging slowly, check to see if the lightning cable is working correctly. If it’s not, you’ll need to change it.

Another component to check is the charging port. A blocked or damaged charging port will slow down the charging speed. So, clean the charging port for it to be free of dirt, and ensure the port isn’t damaged yet. A damaged port signals a need for repair.

6. Abnormal Bad Battery Life After An iOS Update

Sometimes, an iPhone battery can turn bad after an iOS update. This issue usually occurs when an unstable version of iOS is updated. The way to resolve this problem is by replacing the unstable iOS with a stable version. You’ll find a software update section when you click the setting button. Click the ‘Install Now’ button and wait for the device to update its operating system.

7. Inferior Battery Performance

Some iPhone batteries perform better than others, so you need to understand your phone’s battery performance.

Also, when batteries age, there’s a high tendency that it might underperform. This is because aging reduces the capacity of batteries to hold a charge. 

When your iPhone battery can no longer have a charge, it can shut down more quickly and frequently. The best solution for this problem will ultimately be to replace the old battery with a new one by consulting a technician.


Battery problems can reduce the lifespan and efficiency of your iPhone. When not properly managed, they can create complex issues. From overheating to slow charging, you can implement the recommendations in this article to get your iPhone battery problems fixed.
