iPad Keep iPad charging to save battery cycle

While charging the battery is used when the device is turned on. The charger circuitry will only work when the device calls for power by dropping below a certain charge. While you will be saving cycles you are missing the best part of the iPad, it is portable!
Do as you wish but I would occasionally use it without being plugged in just to keep some fresh electrons moving. You batteries will last over three years and then you can get them replaced if you still want to use a three years old iPad.

I see. So in a way it works like MacBook which only draws power from outlet when charging/fully charged?
While i ageee with youthat iPad is portable, I can use it in bed and the same can be useful for my iPhone since it retains only half as many cycles as iPad.
Charging to 100% and then draining to less than 15% and then charging back to 100%.
Keeping your battery at 100% is poor for battery health. Li-ion cells don't like being at either extremes 0% or 100%.
You're better off cycling the battery than keeping it at 100%. You see a lot of notebook computer batteries fail because the user keeps it plugged in all the time.

Interesting opinions here. I would recommend to leave the iPad on the charger when you can use it that way without inconvenience, using it without charger until the battery is close to empty once a month, and apart from that not worry about it.
I understand. In fact I occasionally discharge my MacBook just to keep the electrons moving. I think my question is does it draw power from outlet once it’s fully charged? That way it could save a hella of batterycycle when I’m in bed since I can use it like my MacBook.

Yeah. I have looked through several forums and I have been getting mixed opinion. Keeping it plugged temporarily won’t hurt the battery that’s for sure, but I want to know if it draws power from outlet while charging or draws from battery and charging at the same time. I think I would be doing the same to my iPhone to maximize my battery cycle. (Too poor to change battery yearly)

There is nothing on the Apple website under the section ‘batteries’ that say this is true... a cycle is 100% of the battery no matter how you charge it. Use 75% of 100% one day and 25% the next equaling one charge. It doesn’t matter how you do it or what percentage you choose to charge it at... 100% will always be a cycle no matter how you choose to do it. There’s no degradation in a certain way.
Apple is not behind the li-ion battery science. Their concern is user experience and selling new phones every year, not longevity.
Guys like Tesla are doing the ground level research. Based on Tesla and many other battery researchers, charging to 100% is not good for li-ion.
Why is it not good to charge it to 100%? Surely Apple would prevent that happening (stop it charging at 90% etc) so it would prolong the life of it?
You seem to think Apple is your grandmother. Their job isn't to protect you at every turn or ensure your device lasts as long as possible. Tim Cook's compensation depends on the annual revenue and profit performance of the company.
When you perform a saturation charge to 100%, the cell voltage becomes very high which increases the likelihood of unwanted side reactions known as solid electrolyte interphases. Think of it as a layer of "dirt" on the electrodes which reduces charge capacity. The higher the charge, the further away the electrodes are from their thermodynamic equilibrium and the electrodes are at their most reactive state. It will even slowly react with the electrolyte. The chemical reactions are not perfectly reversible which is why batteries degrade in the first place. In layman's terms, a saturation charge stresses the battery much more so than an 80% charge.
Apple needs a long runtime to fulfill user and marketing requirements. They could sell the iPhone with a 10 hour battery life browsing the Internet based on 500 charge cycles. Or they could advertise an 8 hour battery life based on 1,000 charge cycles. Guess which one most companies prefer to advertise?
My iPhone 7+ is often run off the charger during work, while streaming music. That way, it is at 100% for long periods. Battery health: 100%.
My wife‘s iPhone 6 (non-plus) is usually doing fast charging using the 12W-iPad charger, since the beginning. Battery health: 97%.
Besides, I think I once read an article about Apple showing 100% charge, but will in fact only charge up to safe levels of some 85% or 90% (can’t remember the exact number). Same for the lower levels: When an iDevice shows 0%, it has in fact some 20% left, in order to make sure it doesn’t come down to potentially harmful battery levels.

Using iMazing to check my 1st generation iPad Pro 12.9 is reading 99% and 184 cycles. I don't play games. Using ForScore, Facebook, Twitter, gmail etc.
Awesome, I was thinking that I will have to get a new ipad when the battery dies.
This made me so happy, I am in love with my ipad.
