How many hours of recording 24/96 CAF files does the ipod touch 7 battery get?  Assuming WiFi turned off, screen on but dimmed.

I've never tested it until the battery is dead, but I've gotten 4 hours of audio no problem. I think if I were at a festival or a show with a lot of bands I could easily plug in a USB battery between sets and make it until it was out of storage.

The 4 hours of audio that you mention, was it recording 24/96 CAF files?  Thanks.

Trying it now with a new iPod Touch 7.  Can't seem to get it to record 96 kHz at all.  I'll post later how long it runs it 48 kHz CAF, but this won't work for me I'm afraid.

24/48. That's as high as I record. I can't hear the difference at higher bitrates.

EDIT: If I recall correctly, I had about 40% battery left. So in theory on my iPod I could record 7 hours without charging. Haven't tested that though.

Good news and bad news.  The iPod Touch only recorded for 3 1/2 hours at 48 kHz (CAF files).  But when I upgraded to iOS 15.2 from 15.1 I suddenly find 96 kHz enabled in Apogee Metarecorder as normal for my iPhone.  I'm charging it up again and will test the battery life to see if the system upgrade helped that at all.

Records fine at 24/96 CAF files in Meta-Recorder, with screen brightness dimmed and Meta-Recorder Input Monitor off, airplane mode on.  I got 4 1/2 hours this try.  I will try a few more times to see if I can optimize the iPod any better to get longer times.  It does recharge quickly.

Approximately, how quickly does it recharge?

I'll have to measure it, will try with a fast charger and see how that goes.  I checked my iPhone Xr yesterday, it records for 11 1/2 hours (24/96 CAF) with screen dimmed in airplane mode.  The battery registers 92% of new capacity (bought two years ago but not much used during Covid music hiatus).  But my old iPhone 6s, which the Xr was bought to replace, registers 90%, although its recording life is half what it was when new.  So I'm not sure that reported metric is at all useful.

Takes about an hour and a half.

Has anyone tried recharging an iPhone with a portable wireless device while recording (for example running Metarecorder and a DPA MMA-A).  Is this possible without introducing audio artifacts, or frying the MMA-A even?

Do you mean like mag(netic) charging while the lighting port is being used?

Using the Shure MV88, placing iphone on charger disconnected the mic.

Apparently some of the lightning splitters can maintain audio connection while charging, but the 3 I tried failed.

I can try wireless charging a phone running a dvice this weekend, if nobody else gets to it before then...

I just ran a real quick test using the Shure Motiv app. I started a recording (4061 > MMA-A > iPhone 12 mini), recorded a few seconds, then set the phone on the mag charger. The mics remained connected and I did not notice any apparent noise artifacts on the immediate playback. The WAV has not been analyzed.

On a separate issue, I cannot seem to get the Motiv app to recognize the stereo signal, it automatically sets to mono.
