How Often Should You Charge Your Phone?


Are you uncertain about the best practices for charging your phone? Would you like to know how often should you charge your phone? I will answer those questions and more in this blog post.


How Often Should You Charge Your Phone?


Does your phone’s battery last as long as it’s supposed to? Or does it die prematurely?


Most commercial smartphones that are currently on the market have lithium-ion batteries which should have between 300 to 500 charge cycles or a lifespan of 2 to 3 years according to the manufacturers.


Are the statistics above consistent with your phone? Or does the lifespan of your phone’s battery seem significantly shorter?


If these statistics are consistent with your phone’s battery, then you probably have good charging habits.


However, if your phone’s battery life seems significantly shorter, this is generally a result of poor charging habits over an extended period of time.

How Often Should You Charge Your Phone?


Charging Your Phone Often

You should charge your phone as often as you need to because this plays a significant role in the lifespan of your battery. Short charging cycles are best, the more often you top up your battery the better.


To maximize your battery’s lifespan you should try to keep your battery capacity between 65% to 75% and top it up for every 10% drop in the battery level. However, this is not practical, this is simply to maximize your battery’s lifespan.


This is necessary because the old Nickle batteries function in a different manner than that of the lithium-ion batteries that we have today. There are a few things that negatively affect the lithium-ion batteries:


  • Extreme battery levels should be avoided, having your battery level extremely low or extremely high is bad.
  • Depth of discharge, which refers to how much of your battery capacity is used before you recharge your phone.
  • High temperatures accelerate the deterioration of your phone’s battery capacity.


Misconceptions About Charging Your Phone That You Should Avoid:


  • Your battery will lose capacity if you do not repeatedly recharge it when it’s partially drained.
  • Your battery must be completely drained and recharged to 100%.


These suggestions are true in regards to the old Nickle batteries, but they do not apply to the lithium-ion batteries in our phones today.


Constantly draining and recharging your lithium-ion battery to 100% will shorten the lifespan of your battery, so you should avoid doing this.


How Deep Discharge Negatively Affects Your Battery:


Charging Your Phone

When your battery goes through charge cycles, the internal structure of the battery starts to change.


The lithium count will slowly decrease as more lithium remains in the anode through normal usage.


A restrictive layer will be formed as a result of this, this layer is known as the solid electrolyte interface which gradually increases the battery’s internal resistance, which lowers the battery capacity.


What Makes The Restrictive Layer Grow Faster?


  • Deeper discharge
  • High discharge rate, this refers to how fast the battery loses its charge
  • Low battery level


The older your phone is, the more your poor charging habits will damage the battery.


What Is Considered Deep Discharge?


There is no limit, the deeper you discharge your battery, the more stressful it is for the battery.


Regularly topping up your battery extends the battery life of a lithium-ion battery, and allowing your battery to fully discharge (run your battery down to 0%), is the most stressful thing for the battery.


What’s Considered A Low Battery Level?


This is quite simple, the closer your battery capacity is to 0%, the more stressful it is for the battery.


Likewise, when charging your phone, if your battery capacity exceeds 75% it becomes more harmful the closer you get to 100%, according to the experts at Battery University.


There’s An Exception To This Rule:


If your phone’s battery is at 75% capacity and you’re using it and you realize that it’s staying at 75% for a very long time and then it suddenly drops to 60% within a few seconds.


Or if your battery dies when you know that the battery has not been fully depleted. If you experience any of these things, you must do a full discharge then fully recharge your phone to 100% to recalibrate it.


How To Calibrate Your Phone’s Battery:


  1. Run your phone’s battery down until the phone shuts itself off, do not charge it in between.
  2. After the battery dies, charge your phone to 100% capacity while the phone is turned off.
  3. At 100% capacity, unplug the phone from the charger and turn it on.
  4. After you turn the phone on if the battery capacity isn’t at 100%, you should charge it to 100% then unplug it.


Doing this will recalibrate your phone’s battery and it will start working correctly again. Even though it’s necessary to recalibrate your battery if it’s not working correctly, doing this is still bad for the lifespan of your battery.


Now You Know How Often You Should Charge Your Phone:


Now you know how often you should charge your phone, and you know what you should and should not do to maximize the lifespan of your battery.
