At What Percent Should I Charge My iPhone?

From the moment we receive our iPhones, we are told to keep them charged, but we’re rarely told at what percent they should be charged. It’s important to know the best practices for charging your iPhone, as charging it too much or too little can have damaging effects on the battery life. So, at what percent should you charge your iPhone for the best results?

Charging to 100%

You may have heard that you should never charge your iPhone to 100%, but this isn’t the case. A full charge isn’t damaging to your iPhone’s battery life, as long as you unplug it soon after it reaches 100%. Letting your iPhone battery charge to 100% and leaving it plugged in for extended periods of time can damage the battery, as it is constantly being overcharged.

Consequences of Overcharging

The consequences of overcharging your iPhone can be severe. Overcharging can cause heat to build up in the battery and reduce the number of charge cycles it can withstand. It can also cause the battery to swell and damage the casing of the phone. This is especially true in older models of iPhones, which don’t have the same battery protection as newer models.

Charging to 80%

Most experts recommend charging your iPhone battery to 80%. This ensures that your battery is charged enough to last throughout the day, but it also prevents it from being overcharged. Charging to 80% also helps keep the battery cool and reduce the risk of it being damaged by overcharging.

Frequent Charging

If you’re worried about your battery not lasting throughout the day, you may want to consider charging your iPhone more frequently. Frequent charging is better for your iPhone’s battery than letting it run down to 0% and then recharging it. This is because the battery is only being charged for a short period of time and won’t become overheated.

When to Avoid Charging

There are certain times when you should avoid charging your iPhone. For example, it’s best to avoid charging your iPhone when the temperature outside is very hot or cold. This can cause the battery to become overheated or overcooled and damage the battery. It’s also best to avoid charging your iPhone when it’s exposed to direct sunlight.

Charging with a Case

If you use a protective case on your iPhone, you may want to remove it before charging. This is because the case can block the heat from escaping and cause the battery to become overheated. It’s also important to make sure that the charging port is free from any debris or dust, as this can also block the heat from escaping.

Using a Wall Socket

When charging your iPhone, it’s best to use a wall socket rather than a computer or laptop. This is because wall sockets provide a consistent and stable power supply, which is better for charging the battery. It’s also important to make sure that the wall socket is certified by the manufacturer, as using uncertified sockets can damage the battery.


Knowing when and how to charge your iPhone is important for preserving its battery life. It’s best to charge your iPhone to 80%, avoid charging it when it’s exposed to extreme temperatures, and make sure you use a certified wall socket. Following these tips will help ensure that your iPhone’s battery stays healthy and lasts for a long time.
