my iPad says I don't need an update. I'm 10.3 and it runs slow and a lot of videos won't play. What can I do?

The iPad that you have is not able to be updated past the point that it is at. It’s hardware will not support any updates beyond the point that it is already updated to. This is why it tells you that you are up to date. The only thing that you are able to do at this point if you want to update is to buy a more current device that has the hardware to support the updates.

Your iPad is old and cannot be upgraded any farther than iOS 10.3.3.

I am sure why your iPad is slow and why you cannot view videos.

I have a newer iPad that is still running iOS 10.3.3 and I can still view videos just fine.

How much internal data storage space is left inside of that iPad?

Try all of these tips and leave each tip active together.

DO NOT simply try every tip individually, expecting just one tip to be a performance “cure all”.

Many of these tips are designed to work together to help improve overall iOS/iDevice performance.

Good Luck!

Also,

If your iPad has been stuck on iOS 10.3.3 for the past few years, with no upgrades/updates forthcoming, then you own a 2012, iPad 4th generation.

A 4th gen iPad is a NEARLY 8-year old device, now!

These older iPad models are too old, now, too underpowered and completely incompatible with any of the current and future versions of iOS/iPadOS.

It is what it is, today, in the year 2020!

Apple supports new iPad models for up to 5-6 years with third party app developers supporting these iPads for another, additional 2-3 years after!

So, that is a total of between 7-9 years of iPad/iOS support!

Older iPad models, like the iPad 2, 3, 4 and 1st gen iPad Mini have ALL reached this support limit!

If you need an iPad that can run the latest and greatest versions of iOS, as well as, the most current apps available, then, you need to purchase a new iPad from Apple or a discounted, refurbished iPad from Apple’s Refurbished & Clearance section of Apple’s Website or a new or refurbished iPad from an Apple authorised, third party retail or online reseller OR other trusted sources for new or used Apple products.

These old iPad 2, 3, 4 and 1st gen iPad Mini models are nearing 8 and 9-years old, now.

The amount of older, compatible, available apps for these old iPad models has dwindled significantly since the beginning of 2020!

Getting older versions of apps for these old iPad models, initially from Apple’s iOS App Store is getting very difficult and very problematic and this issue is getting, painfully, much worse, now, in 2020!

As of the beginning of 2019, many, MANY third party app developers are all more quickly and completely permanently dropping older app support for all old 7, 8 and 9-year iPads that are running 2-3 year old and earlier iOS versions ( iOS 10 and earlier ).

Third party app developers are removing all of their older, legacy versions of their apps from Apple's App Store servers, now.

Third party app developers no longer want to support these 8 and 9-year old or older iOS devices, any longer!

Older versions of apps are, soon, going to be gone for good, now!

These old iPads are now reaching their complete end of life and support.

So finding older versions apps for older iPads, while still possible, currently, will be a very tough challenge, now, in 2020.

Old iPads that can no longer be upgraded/updated will have NO MORE APPS AVAILABLE for initial download, at all, soon, from the Apple iOS App Store, for such old iOS devices in the very near future.

Older versions of apps for these older iPads will be completely gone, at some point, in the very foreseeable future.

Old 8 and 9-year old iPads will be pretty much obsolete by the end of the 2020 year!

Again, it is what it is, today, in the year 2020!

You will never get any more older versions of popular apps for these old iPads, any longer.

The apps that these old iPads already have on them, and still work, will be the apps these iPads will be stuck with!

Basically, these old iPad models are just good for FaceTime and somewhat limited Web browsing via some other, more up to date third party Web browsers and NOT using that nearly 4-year old iOS Safari Web browser.

So, this is REALLY NOW the time to seriously consider a new or discounted, refurbished iPad from Apple or other Apple authorised resellers.

A lot has happened with iPad and iOS in 7-9 years and in the past 2 to 3-1/2 years since iOS 9 and 10.

As an example and compared to that nearly 8-years old iPad 4th generation model,

The cheapest, baseline 2019, 10.2 inch screen 7th gen Apple iPads have a 1/2 inch larger retina screen, it is overall lighter, in weight, newer, more powerful and approx. 2-1/2 times faster 2.3 Ghz, A10 Fusion processor ( CPU ), AT LEAST 3-4 times the internal RAM, with the 2019, 7th gen iPad having 3 GBs of internal RAM, iPadOS 13 support, with much better and improved multitasking features and much fuller support for externally connected data drives, Apple Pencil and Apple Smart keyboard cover support and have better audio speakers and better/improved built-in cameras.

In addition, if you search online and look at various, reputable online Apple device resellers, you can usually find this 2019, 7th gen iPad at discounts of between $60 U.S.D and $100 U.S.D. depending on storage size and whether it is a WiFi ONLY model or a WiFi/cellular data model.

This is the harsh reality for these 8 and 9-year old, OR OLDER, iOS devices, now!

Sorry & Best of Luck to You!
