When transferring multiple photos via AirDrop, I found that while there isn't a strict MAX number officially stated by Apple, practical limits like device storage, Wi-Fi stability, and processing power do affect how many images can be sent at once. For example, selecting around 25 to 30 photos at a time tends to work reliably on my devices without connection drops. To improve transfer speed and success, I always ensure both devices have Wi-Fi and Bluetooth turned on, and Personal Hotspot disabled, as hotspot activation can interfere with AirDrop connectivity. Setting AirDrop receiving mode to "Everyone" also helps avoid missed connections. If you need to send more than 25 photos, breaking your batch into smaller groups improves responsiveness. Alternatively, I use third-party tools like FoneTool for larger file transfers — it works well for bulk photo transfer between PC and iPhone when AirDrop hits limits. Lastly, ensure your devices are geographically close (within Bluetooth range) during transfer for a stable connection. I've also noticed that newer iPhones with faster Wi-Fi and Bluetooth chipsets tend to handle bigger batches better. In summary, while you can AirDrop dozens of photos in one go, splitting very large collections into smaller transfers and optimizing device settings makes the experience smoother and quicker.
