How to Calibrate an iPhone Battery in 8 Easy Steps.
How to Calibrate an iPhone Battery in 8 Easy Steps: The material properties of lithium-ion batteries require constant usage to maintain peak performance. For this reason, Apple recommends discharging and recharging the battery once a month.
What is Battery Calibration?
Battery calibration is a way to correct the battery statistics that go wrong and show incorrect battery time.
The process includes resetting your battery statistics so that your phone shows the actual percentage of the remaining charge.
Although battery calibration is an important part of the iPhone maintenance;
many users don’t know its usefulness, when to calibrate the battery, and how to do it correctly. So, let’s get to know the process in detail
Ideally, you should calibrate your battery once every month and also after every OS upgrade. Calibrating your battery ensures two things –
Conditions the battery.
Helps software to calculate the range of battery life.
Whenever you notice diminished battery life, calibrating the battery may fix battery life issues. Battery technology is all about ions.
Periodically charging and draining the battery keeps these ions moving. Most of the batteries today are lithium-ion and require constant usage to maintain peak performance.
This is why discharging and recharging the battery once every month is highly recommended.
The software calculates the amount of charge available in the battery. There’s a high possibility that battery-intensive features are part of the new iOS upgrade.
Although these upgrades come with improvements to battery life, it’s advisable to calibrate the iPhone battery to maintain the battery in good working condition.
It has already been established beyond doubt that calibrating a battery improves battery life, just as calibrating a mechanical engine improves its performance.
Step By Step Battery Calibration
The following process is what I consider to be the gold standard of iPhone battery calibration. For some, it might not be possible to follow all of these steps.
If you are an on-call professional or hopelessly addicted to your iPhone, you might not be able to turn off your iPhone overnight or even for a few hours.
At the bare minimum, you need to drain the battery until the device shuts off, charge your iPhone to 100%, and reset it by holding down the sleep/wake and home buttons until you see the Apple logo.
Use your iPhone until it shuts off automatically. If it is near 0% battery life and you want to drain it faster, turn on the flashlight, turn up screen brightness all the way, and play a video, preferably streaming from the Internet.
Let your iPhone sit overnight to drain the battery further.
Plug your iPhone in and wait for it to power up. Make sure to use the charger supplied by Apple or one that runs at the same wattage and amperage.
Hold down the sleep/wake button and swipe “slide to power off”.
Let your iPhone charge for at least 3 hours. Older iPhones should be charged for 5 hours. The charge progress indicator is not displayed while your iPhone is turned off.
With the charging cable still connected, press the sleep/wake button for about a second to start up your iPhone.
When the iPhone has booted up, hold down the sleep/wake and home buttons until you see the Apple logo.
If you have a newer iPhone, without a physical Home button, hold the volume up and sleep/wake button.
When your iPhone is back online, remove the charging cable.
