Often yes, but only when the microphone setup is designed for it. Most phones have a single USB-C or Lightning port, and a plug-in mic receiver occupies it. There are three ways around that: a receiver with its own charging port that passes power through to the phone, an adapter built to split power and audio, or a transmitter that connects over Bluetooth and leaves the port free. Each works, each has catches, and manufacturers document some combinations but not all.
Why the port is the problem
On iPhone 15 and later, and on USB-C Android phones, one port does both jobs. Apple lists microphones among the USB-C accessories an iPhone can use through the same connector it charges from. Some receivers run entirely on the phone's power: DJI says its Mic Series Mobile Receiver is powered by the phone when connected with its USB-C plug.
The receiver itself draws little. RØDE lists the Wireless Micro's USB-C receiver at 5 V and 0.1 A, about half a watt, and Apple says an iPhone 15 or later can supply up to 4.5 W to small accessories. The real issue on a long recording is that the phone's own battery keeps draining while its only port is taken.
Option 1: a receiver with a charging port
Several makers build a USB-C port into the phone receiver, so you plug the charger into the receiver and the phone charges through it. What each maker documents differs:
| Kit (as documented) | Charge the phone while recording? | What the maker says |
|---|---|---|
| DJI Mic 2 receiver with phone adapter | Yes, through the receiver's USB-C port | DJI's compatibility list marks some phone models that do not support charging and use at the same time |
| DJI Mic Mini receiver, DJI Mic Series Mobile Receiver |
