• A phone like the Pixel 8 Pro with its massive battery capacity takes forever to fill up at this speed.
• You might get a few percent boost over half an hour—enough for an Uber ride, not a full recharge.

Now, let’s break it down with numbers:

So sure, the answer to “can iPhone 15 charge other phones” is yes. But is it practical? Only if you’re desperate or just topping off.

Factors Hindering Effective Charging: USB Type-C vs. Proprietary Ports

Let’s talk about the real struggle—compatibility issues between devices that should play nice but don’t.

1. Apple finally ditched Lightning and embraced USB Type-C, which opens doors… sort of.
2. Despite having a universal port, Apple uses its own charging protocols, limiting how much juice it can send out.
3. Some Androids expect specific handshake signals before accepting reverse power, and iPhones just don’t speak that language well enough yet.

You’ll also run into mismatched expectations:

• Your friend hands you their phone expecting fast charging—but your iPhone delivers slow trickle instead.
• Data lines in cables matter too; some only support power or limited data transfer, causing more hiccups.
• Cable quality and connector types can mess things up even more if they’re not fully spec’d for power delivery.

So yeah, while technically the answer remains “yes” to “can iPhone15 charge other phones,” don’t expect miracles unless both devices are on speaking terms tech-wise—and most aren’t yet.
