How to Calibrate Your Phone's Battery to Correct Inaccurate Charge Percentages

Here we can see, “How to Calibrate Your Phone’s Battery to Correct Inaccurate Charge Percentages”

If you’ve ever noticed that your phone’s battery drops from 60% to 50% in a matter of minutes, only to stay at 50% for what seems like an eternity, it’s likely time to calibrate the battery.

What is battery calibration?

The Android operating system must keep track of your battery and charge levels to notify you whether your battery is full or empty. The issue is that it can become corrupted and start presenting data that isn’t accurate, which can force the phone to shut down before it reaches 0% battery life. Aging can also contribute to this data disparity.

Over time, all batteries degrade, and an older battery can no longer store as much charge as it once could. However, the software that runs on your phone does not normally account for this degradation when presenting the battery status on the screen.

Calibrating your Android battery means instructing the Android OS to adjust this information so that it accurately reflects your current battery levels. It’s critical to note that this procedure does not truly calibrate (or improve) the battery. Battery calibration does not extend the life of your phone’s battery, and it will simply aid in the proper presentation of battery statistics on the phone.

Why Does Your Phone’s Battery Percentage Change?

Because this is a problem that affects most battery-powered products these days, this method should work on iPhones, Android phones, and even tablets and laptops (almost all of which use lithium-ion batteries). While it’s not a major issue, it can be aggravating when your phone claims it has 25% battery life left, only to discover that it’s on the verge of dying.

The explanation for this is straightforward. Batteries degrade naturally over time, and their capacity gradually diminishes. However, your phone isn’t always accurate in this regard—if your battery has declined to 95% of its original capacity, your phone may still show it like 95% full rather than 100% full (the “new normal”). This can be fixed by recalibrating your battery.

How to Calibrate the Battery in Your Phone

  • Fortunately, adjusting your smartphone’s battery is a simple process that only requires a little time and patience.
  • Allow your phone to completely drain to the point where it shuts down on its own. When you try to turn on the phone, you’ll normally be greeted with a dead battery icon before the phone shuts off again after a few seconds.
  • Then, without turning it back on, plug your phone into the charger and let it charge to 100%, leaving the phone off the entire time.
  • Some people recommend putting it on the charger for an extra hour or two to ensure the battery receives the most amount of charge possible, but this is entirely up to you and not necessary.
  • Please turn your phone on after that and wait for it to boot up. Once it reaches the home screen, please double-check that the battery meter reads 100%, then unplug it from the charger.
  • Once you’ve unplugged your phone, the battery will be adjusted, and you’ll be able to use it normally again.

How Often Should Your Battery Be Calibrated?

There’s no set guideline for how often you should calibrate the battery in your phone. And, theoretically, if you don’t care about the accuracy of the %, you don’t need to do it at all, especially if you’re already diligent about keeping the battery charged.

You should calibrate the battery every two to three months if you want the most accurate battery stats. You can go longer if you like (I only do it once every six months or so), but keep in mind that your battery percentage may be inaccurate.

When it comes to Samsung cellphones, how do you calibrate the battery?

Samsung smartphones have a feature called ‘Quick Reset,’ typically used by technicians to calibrate phones with erroneous battery statistics. Here’s how to adjust the battery on Samsung devices with this option.

  • Make sure your phone isn’t connected to the charger and use it until it reaches 5% battery life.
  • Enter the following code into the phone dialer app: *#0228#.
  • A pop-up menu with the option ‘Quick Start’ displays.
  • Then press “OK” after pressing “Quick Start.”
  • Wait for the display to turn back on, then check to see if the battery % has decreased.
  • Recharge the phone to its full capacity.
  • Turn off the phone, then on again, before unplugging the charger.
  • Repeat steps 2 and 3 twice more.
  • Turn the phone back on, open the dialer, and then type: *#9900# with the charger plugged in and the battery at 100%.
  • Scroll down and tap “batterystats.bin reset.”
  • Restart the phone after exiting the menu.

It’s important to remember that this isn’t something you should frequently do. Even if your battery is completely dead and your phone would not power on, it still contains enough reserve energy to prevent system damage. However, you should avoid poking the tiger with a stick. At most, they perform this procedure once every three months. If it’s needed more frequently than that, you’ve got greater problems on your hands.

Calibration of a battery does not make it last longer.

Other articles may address how adjusting your battery might extend its life or improve its performance. However, to cut a long tale short, it does not.

In reality, the ideal method to maintain your battery healthily is to execute shallow discharges rather than running it down to zero frequency, which is why you should calibrate it only every few months or so.

According to Battery University, there is no apparent risk in calibrating your phone’s battery, and it is advised that you do it regularly.

  1. Is it bad to calibrate a battery?

Calibration of batteries is a fallacy, and it’s a holdover from the days when nickel-based batteries were recommended.

After your phone has been exposed to extreme cold or excessive heat, or if your phone is exhibiting the following symptoms, you should calibrate your battery every two to three months. Showing a full charge before suddenly decreasing to a dangerously low level. For long periods, remaining “stuck” on a single charge percentage.

  1. Why is my phone’s battery dying so quickly?

Third-party programs can also get stuck and consume the power, in addition to Google services. Check the battery information in Settings if your phone keeps draining the battery too quickly, even after a reboot. If an app consumes too much battery, Android settings will highlight it as the culprit.
