Battery calibration is a myth. At least, it could as properly be those days. It’s a relic of tips for older, nickel-primarily based totally batteries. But the battery in your iPhone or iPad makes use of lithium-ion, and calibrating it isn’t an excellent concept.
When we speak approximately calibrating a battery, we suggest charging it all of the manner to 100% then draining it right all the way down to 0. The concept is that doing this teaches your iPhone, iPad, or iPod how tons electricity the battery can hold, permitting your tool to make the maximum of it.
There became a time whilst Apple advocated calibrating your tool’s battery each month. They don’t anymore.
These days, it’s now no longer simplest needless to calibrate the battery to your iPhone, iPad, or iPod, it’s downright unfavourable to do so.
In this post, we’ve defined why this is the case. And greater importantly, we’ve given you pointers you could use to lengthen the battery existence of your iPhone, iPad, or iPod.
What’s incorrect with calibrating the battery in an iPhone, iPad, or iPod?
To recognize why it’s a awful concept to calibrate your iPhone, iPad, or iPod you want to recognise a touch bit approximately the lithium-ion battery interior it.

iPhone, iPad, and iPod contact gadgets all use lithium-ion batteries.
Your battery has a lifespan
Every battery has a lifespan. At the start of that existence, it shops a complete price, which we check with as its most capability. As the battery a while, its most capability receives smaller and smaller as compared to whilst it became new. Eventually, that battery will die.
The lithium-ion battery in iPhones, iPads, and iPods fees faster, lasts longer and takes up much less area than preceding generations of batteries. But it nevertheless a while with use. When your tool is years old, the battery won’t last up to it did whilst it became emblem new.
In fact, Apple expects an iPhone battery to lessen to 80% of its most capability after 500 price cycles. That’s virtually quite exact. And for an iPad, you could nevertheless assume 80% of its most capability after a thousand price cycles.
But in the end, the ones batteries will die. They all do.

After some years of use, the most capability of my iPhone 6S battery decreased to 74%.
What is a price cycle?
One price cycle refers to the usage of 100% of your battery’s capability, however you don’t want to apply it in a single go. If you drain your battery from a complete price to 50%, that equals 1/2 of a price cycle. You want to do it two times to burn up a whole price cycle.
There’s no want to absolutely price your iPhone, iPad, or iPod. And there’s no want to empty it all of the manner to 0 earlier than plugging it in again. Apple’s recommendation is to, “Charge your Apple lithium-ion battery every time you need.” Let the price cycles paintings themselves out.
Your battery doesn’t like extremes
So the lithium-ion battery in your iPhone or iPad goes to age as you operate it. That’s not possible to keep away from. What’s now no longer not possible to keep away from are the acute conditions we are able to positioned our gadgets in that hastily accelerate the growing older procedure.
I’m regarding excessive price stages and excessive temperatures. Your battery doesn’t like both of them.
What is an excessive price stage?
“Extreme price stage” refers to both 100% or 0% price. When a lithium-ion battery spends too lengthy at 100% price, it reduces the most capability of that battery. And whilst a lithium-ion battery reaches absolute 0, it holds a price again.

It’s awful for battery fitness to go away your tool with out electricity.
Apple designs its software program to encompass a buffer across the battery. So, whilst your tool says the battery’s at 100% price, it isn’t really. It stops charging earlier than it receives that far.
Similarly, whilst your iPhone, iPad, or iPod turns off due to the fact the battery died, there’s virtually nevertheless a chunk of price left in it. That’s the way it shows a low electricity icon while you strive turning it again on.
As the price stage drains even greater the low electricity icon stops appearing, however Apple nevertheless left a buffer in there. If you go away your iPhone or iPad with out electricity for lengthy sufficient, the price in the end reaches absolute 0. And then your battery’s carried out for.
What is an excessive temperature?
The lithium-ion battery to your iPhone or iPad is happiest among 32° to 95° F (0° to 35° C). When the ambient temperature round your tool receives warmer than 95° F or chillier than 32° F, then we magnificence it as an excessive temperature.
