how much does apple charge to replace an iPad 2 cracked screen

Your iPad2 is obsolete - and no longer supported for repair. Your only hope for repair would be an independent repair agent - and the cost, even if repair remains possible, is unlikely to be economically viable.

Be aware that repair will result in the iPad being erased. Any third-party Apps will be permanently lost - as all 32-bit Apps, compatible with iPad2, have long since been withdrawn from the Apple App Store.

As older versions of Apps are removed from the Apple App Store, you’ll not be able to (re)download or install them - which may severely limit the usefulness and utility of your iPad if you should you ever, as now, need reset or restore your iPad. As such, if you want or need to access most current Apps, requiring more recent versions of iOS, you’ll need to consider replacement of your iPad with a newer or current model.

Of current models, even the entry-level iPad8 has specifications and capabilities that will massively outperform you current iPad - and is compatible with the vast majority of current Apps. Other models are more powerful still.

I hope this information provides helpful and succinct clarity as to your available options - and the limitations of your current iPad.

Too much and is probably NOT repairable/replaceable , any longer, as this is a nearly 10-year old iPad model which Apple stopped supporting over 4 years, ago.

Time for a new or much, MUCH newer, used iPad model.

Sorry & Best of Luck to You!
