This Is Why Your iPhone Dies Even Though It Still Has 20% Battery Remaining

Many iPhone users will undoubtedly be familiar with this annoying problem. The battery indicator on lots of iPhone devices fluctuates constantly and your device will often switch itself off, despite the fact it says there is still 20% battery left. Well, here’s why this happens and what you can do to fix it.

Long live the smartphone! This useful little device has revolutionised people’s everyday lives, but not just for the better. Researchers have even carried out studies that prove our muscles have changed and become slightly deformed due to our excessive smartphone use.

Smartphone dangers

But this isn’t the only downside. Time and time again we are warned not to fall asleep next to our mobile phones, not to leave them charging next to our beds and not to use cheap chargers or other cheap electronic accessories with our already quite short-lived devices.

But what really is annoying is an iPhone’s battery life. Users are always complaining that, from time to time, their phones suddenly die without warning, despite the fact that the indicator says there is still 20% battery left. This can be really annoying, especially since it makes your device quite unreliable.

Why iPhones suddenly die

Often, smartphones don’t switch themselves off when they reach 0% battery, but actually much earlier than that. If this happens to your iPhone, you might have also noticed that it then takes an extremely long time to charge it back up to full battery, i.e. 100%.

But why does the battery indicator on our phones not work properly and why do our devices turn themselves off completely out of the blue? This is partly due to the lithium batteries inside the phones. These batteries should, in theory, never be completely dead or completely full, which is why you should actually disconnect your phone from the charging cable when it reaches 90%.

Extreme fluctuations aren’t good for your iPhone

Extreme fluctuations, i.e. a completely full and completely empty battery, damage the device. Experts, therefore, assume that a safeguard has been built into these smartphones in order for the device to protect itself. This safeguard is also able to interfere with the charging process and prevent the actual battery from reaching 100%.

So, in order to protect itself and the battery from dying completely, your iPhone turns itself off when the battery gets relatively low. This not only protects the battery but also ensures that the remaining juice left in the battery can be used for a safe and controlled power-down. The ‘Please charge’ signal is then able to appear using the remainder of the battery.

Extreme temperatures can also damage your device

Extreme hot and cold temperatures can also damage your phone’s battery. As a result, you should be careful with your smartphone and not expose it to extreme temperatures for too long (eg. By leaving it in the car in summer or winter).

Due to this safeguard feature, your iPhone, unfortunately, gets confused and switches itself off when you least expect it. And this always seems to happen at the absolute worst times! Check out the video above to find out how you can fix this issue - but be warned. This does, unfortunately, involve removing the safeguard feature from your iPhone!
