I just bought an 8th generation iPad from the T-Mobile store by me Wednesday night. I charged it Wednesday night when I went to bed when it was around 50%, and used it all day yesterday for work, and since it still had 68% I did not charge it. Been using it since 7 am and it still has 55% remaining, have to say the battery life is amazing.... the question is for its second charge, when should I charge it again, at 20% or less in order to continue getting maximum life and time out of the battery? Also, I had the store agent install a Zagg glass screen protector on it, what is the best way to clean fingerprints from it, want to keep it nice since it is the first new iPad I ever purchased, I have bought used ones before, but this one like my MacBook Air and iPhone XR is my baby.

Good luck keeping the screen smudge-free. You can clean it and then not use it I suppose. I wipe mine with a cloth used for cleaning eyeglasses. I suppose a soft cloth with window a cleaning product would be fine. I would spray the cloth, not the iPad.

It does seem to hold a charge well. I just bought one myself, first iPad I've owned. With other devices, I'll recharge any time after it goes under 50 percent, but have gone below 30 as well. I'm not sure that frequency matters if you check on it and unplug it soon after it is fully charged. I could be wrong, but any advice on that which you're likely to get here will be speculation, based only on casual observations. It would take a truly scientific study to determine actual optimum strategies for recharging. If such a study has been done, I imagine it's on the internet somewhere.

I have a screen cleaning kit that I have used on my MacBook Air and iPhone, the iPhone has a screen protector but from a different company, the kit came with a soft microfiber cloth I wiped the finger prints off with this morning, was wondering if the screen cleaner is safe for the Zagg screen protector.

I read something about once you’re charging over 80%, things degrade faster/it stresses the battery out more, so threw a little automation together to let me know when it had reached that point. Sometimes I see it, sometimes I don’t, but I figure it probably helps.

I’d be super careful about using any chemicals on it. Dry/very slightly damp (with water) soft cloth. I’ve definitely never used the sleeve of a hoody to wipe it down. Not in the last ten minutes, anyway.

I like to use Woosh!

The whole charging thing is a topic that’s blown way out of proportion on here. Charge it whenever you want. Some say the optimum spot for Li-ion batteries is 20-80%. I do try to charge mine before it goes under 20, but as far as stopping at 80% or not letting it reach 100, I couldn’t care less. I use the same charging habits across all of my devices and have never had an issue 1-2 years later. As for cleaning the screen, a microfiber cloth is all you need. Just wipe it when it gets unsightly. I like to use little alcohol pads too.

Use and charge your device however and whenever you want to. Nothing that you do will have a notable effect on the battery health.

I was thinking that for its first actual charge I should wait for it to get to 20% or a little less, if it ever does, I’ve used it for 2 work days now and it is still at 48%, amazing battery life, but I think I will plug it in tonight when I go to bed. I hate being forced to work from home but with the iPad now I can lay on the couch and do work. Monday I’ll be using the MacBook Air since I have to do a whole end of month report, and think it will be easier to type on the actual keyboard instead of a touch screen, but this 8th generation iPad is awesome. Apple just works.

That was a recommendation for NiCad batteries. Letting them drain down and then charging up completely to 100% was a way to expand the “memory” of the batteries for optimal capacity usage. Li-ion doesn’t have that requirement.

However, if you desire to bring the battery down, turn on a movie at max brightness for a while, or turn on the camera and activate video. Let it record for some time. That’ll bring the battery down a bit before you charge up.

It’s actually nice to have such a long battery life. My old iPad Air 2 with cellular must have been starting to show its battery age, it would last about 6 hours before being at 16%. I gave that iPad to my boyfriend so he could stop using android and use a real tablet 2 years ago and it still works most of the day for him, shouldn’t be too surprised though, my MacBook Air says service battery and still works on battery for about 7 hours.

If you don’t mind, can you share those shortcuts here?

I don’t use screen protectors, so no advice on that specifically. Although, I will point out Apple states you can yes 70% or less isopropyl alcohol and a soft cloth for cleaning.
As for the battery, don‘t get as obsessed as most users here. The basic, simple rules for care are:

• Do your best not to subject the device to extreme cold or heat
• Do not leave the battery unused for long periods, especially at high or low charge levels
• If you do expect to not use your iPad for weeks or more, charge it to about 50% and shut it down

Any other usage will just cause normal degradation, aging — unless it is a defective battery, of course.

Can’t seem to share them as they’re “automations” rather than shortcuts, but the screenshots I posted before show how it’s done. Basically “when battery level rises above 75%” (the UI gives you a slider, so can set whatever level you like), do things (send message, play sound, show notification). Untick any “ask before running” or “show when run” options. Et voila
