Recording audio and video on an iPad, alone, only last as long as the amount of free, internal data storage space you have left on an iPad.
If you own a low, internal data storage, 32 GBs iPad model, screen recording will NOT go very far.
A 32 GBs storage iPad starts out with approx 30 GBs.,after initial internal flash drive formatting.
Minus approx. 6.5 GBs for iOS/iPadOS leaves between 23-24 GBs.
Minus 3-6GBs, for iOS/iPadOS system operational reserve, that MUST BE MAINTAINED AT ALL TIMES, to ensure/insure normal, expected operation of iOS/iPad OS, leaves approx. between 18-20 GBs of actual, usable data storage space.
Even with 20 GBs of actual, usable internal data storage space in an Apple iOS/iPadOS device,
a 32 GBs data storage devices are, now, more quickly, becoming the “new” low storage 16 GBs internal data storage space devices, today, a 32 GBs Apple iOS/iPadOS device has 3-4 times the internal data storage space of older base model, low internal data storage,16 GBs. internal data storage Apple iOS/iPadOS devices.
In reality and in use, in 2022, a 32 GBs internal data storage device is kind of a joke and of limited usefulness, when up to 2TB of internal data storage ( approx. 1.8 TBs or usable internal data storage ) portable tablet devices exist today.
Apple put an end to 32 GBs devices, in September 2021, with the base model iPad now offering 64 GBs of internal data storage ( approx. 50 GBs of actual, usable internal data storage ), which, for a few more years, anyways, has enough storage to make an iPad useful for longer period of time before data storage fills up.
Purchasing a low storage Apple device, to save on the cost of the device, is a false economy.
If your iPad model is a 128 GBs model,
A 128 GBs storage iPad starts out with approx.119 GBs.,after initial internal flash drive formatting.
Minus approx. 6.5 GBs for iOS/iPadOS leaves between 112-113 GBs.
Minus 3- 6GBs, for iOS/iPadOS system operational reserve, that MUST BE MAINTAINED AT ALL TIMES, to ensure/insure normal, expected operation of iOS/iPad OS, leaves approx. between 108-110 GBs of actual, usable data storage space.
If your iPad internal data storage space is getting low on a 128 GBs model iPad, then this can affect the amount of time you can record audio and video, also.
Recording audio and video is completely dependent on the available free internal data storage space on any iOS/iPadOS device.
