We’ve all heard the warnings: don’t let your phone’s battery drain completely, and don’t leave it plugged in all night. But did you know that following the 20 to 80% charge rule could help extend the life of your device? In this blog post, we’ll explain why it’s important to follow the 20 to 80% rule for your phone’s battery and how you can do it.
What is the 20 to 80% charge rule?
When it comes to preserving the life of your smartphone battery, the 20 to 80% charge rule is a must. This rule simply states that you should always keep your phone’s battery between 20% and 80% charged.
This may seem counterintuitive, as many people think that keeping their phone at full charge will extend its battery life. But in reality, it does the opposite!
When you charge your phone to 100%, the battery is exposed to higher levels of stress, which can cause permanent damage over time. Likewise, discharging the battery all the way down to 0% can also cause irreparable damage. Keeping your phone between 20 and 80% charged helps avoid these extreme levels of stress, thereby extending its lifespan.
How does this rule extend your phone's battery life?
When it comes to keeping your phone’s battery healthy and its lifespan extended, there’s a simple rule of thumb: the 20 to 80% Rule. This rule says that when charging your phone’s battery, you should only charge it between 20% and 80%. In other words, you should never let your phone’s battery go completely dead (below 20%) or completely full (over 80%).
The reasoning behind this rule is that lithium-ion batteries are most efficiently charged within this range. If your phone’s battery is left to drain all the way to 0%, or left on the charger after reaching 100%, it will cause strain on the battery over time and reduce its overall life expectancy. This can also result in reduced performance and capacity in the long run.
Therefore, following this 20 to 80% rule will ensure that your phone’s battery stays healthy and lasts longer. It may not seem like much, but following this rule can potentially double the lifespan of your phone’s battery. So the next time you charge your phone, be sure to keep an eye on the charge and unplug it once it reaches 80%.
Are there any exceptions to this rule?
The 20 to 80% charge rule is a great guideline for keeping your phone’s battery healthy, but there are some exceptions. If you’re running low on battery and need to charge it quickly, you may need to go above or below this range. For example, if you’re about to get on a flight and want to make sure your phone has enough battery to last, it’s okay to charge it up to 100%.
Another exception is if you need to recalibrate your battery. Recalibration can help improve your battery’s performance and increase its lifespan. This can be done by letting the battery drop to 0%, charging it back up to 100%, and then repeating this process several times. While this isn’t something you should do often, it can be beneficial for your battery in the long run.
Finally, if your battery drains extremely quickly and you find yourself always needing to charge it, it may be time for a new battery. Replacing an old battery can help extend the life of your phone and improve its performance.
In general, it’s best to stick to the 20 to 80% rule for your phone’s battery health. But if you find yourself in a situation where you need to charge your phone outside of that range, it’s okay to do so occasionally. Just be sure to take care of your phone’s battery and replace it when needed!

How can you make sure you stick to this rule?
Making sure you stick to the 20 to 80% battery charge rule can be tricky, especially if you’re on the go. Fortunately, there are several ways that you can ensure that your phone battery stays within this range:
1. Charge your phone only when necessary. Try not to charge your phone unless it’s below 20% or above 80%. This will help to prevent excessive charging and draining of your battery.
2. Use power-saving mode. If your phone has a power-saving mode, make sure to turn it on whenever possible. This mode helps to extend your battery life by restricting certain features and background processes.
3. Reduce screen brightness. Dimming your phone’s screen brightness can also help to save battery life. The lower the brightness, the less energy your phone will need to use, which means that it won’t need to be charged as often.
4. Limit the number of apps running in the background. Running too many apps in the background can take up a lot of energy, so try to limit the number of apps that are running at any given time.
By following these tips, you can make sure that you’re sticking to the 20 to 80% battery charge rule and helping to extend the life of your phone’s battery.
