Mobile Controller Buying Guide: USB-C or Bluetooth for iPhone and Android (2026)

Touch controls are fine for plenty of mobile games. In shooters, racing games or when you stream PC and console games to your phone, they quickly hold you back. A mobile controller turns your phone into a handheld: the phone sits between two grips with sticks, bumpers and triggers. This guide covers what to look for and four models currently available on Amazon.de.

Transparency: We have not tested these controllers ourselves. The details come from Razer, GameSir, 8BitDo, Apple, Epic Games and the Amazon.de product pages we checked (as of October 2026). We don't list prices because they change constantly.

USB-C or Bluetooth: the key decision

USB-C controllers such as the Razer Kishi V3, GameSir G8 Galileo and GameSir X5 Lite plug straight into the charging port. According to GameSir, the G8 Galileo has no battery and runs on the phone's power. There's nothing to pair, and the makers describe the connection as very low latency.

Bluetooth controllers such as the 8BitDo Ultimate Mobile have their own battery. 8BitDo quotes up to 13 hours of play and about 1.5 hours to charge. The upside: it works no matter which port your phone has.

What matters most

1. iPhone: USB-C only from iPhone 15

Apple says iPhone 15 and later have a USB-C connector. Older iPhones use Lightning, so a USB-C controller won't fit. Razer lists iPhone 15, 16 and 17 for the Kishi V3. For an older iPhone, go Bluetooth. Apple explains that Xbox, PlayStation and other Bluetooth controllers pair through the iPhone's Bluetooth settings. From iOS 16 you can remap buttons under Settings > General > Game Controller if your controller supports it.

2. Phone size, camera and case

Every controller has a supported phone length. Measure your phone without its case and compare:

Big camera bumps can get in the way. GameSir lists a maximum camera depth of 5 mm for the G8 Galileo. Razer says the Kishi V3 works with many cases thanks to a raised USB-C "island", but compatibility depends on the exact phone and case. GameSir's Japanese distributor recommends removing the case for the X5 Lite.

3. Sticks: Hall effect and TMR against stick drift

Stick drift is when the stick registers movement while you're not touching it. Hall effect sticks measure position with a magnetic field instead of wiping contacts. The G8 Galileo, X5 Lite and 8BitDo Ultimate Mobile use Hall effect sticks. The Kishi V3 uses TMR sticks, which Razer markets as drift-free and more precise than Hall effect.

4. Extra buttons, headphone jack and passthrough charging

• Back buttons: the Kishi V3, G8 Galileo and 8BitDo Ultimate Mobile each have two remappable back buttons. GameSir lists none for the X5 Lite.
• 3.5 mm jack: the Kishi V3 (with mic support) and G8 Galileo have a headphone jack. Handy if your phone doesn't. Wired options are in our gaming earbuds buying guide.
• Passthrough charging: all three USB-C models charge the phone through a port on the controller. GameSir's manual says that for the G8 Galileo both phone and charger need PD 2.0 or later, with a maximum of 9 V and 3 A. On some Android phones you have to enable OTG in settings.

5. Games with controller support

A mobile controller only helps if the game supports controllers. Epic Games says you can use controllers in Fortnite on mobile without risking a ban, though Epic can't test every device. Beyond mobile games, the makers list streaming apps such as Xbox Cloud Gaming, PS Remote Play, GeForce Now and Steam Link. Cloud gaming may need a subscription and a stable internet connection, depending on the service.

FAQ

Does a USB-C mobile controller work with an older iPhone?

No. iPhones before iPhone 15 have a Lightning port. Use a Bluetooth controller such as the 8BitDo Ultimate Mobile (iOS 18.5 or later), or pair an Xbox or PlayStation controller you already own.

Do I need to charge a USB-C controller?

Not the G8 Galileo: GameSir says it has no battery and runs off the phone. That uses a little phone battery. With passthrough charging you can charge the phone through the controller while you play.

Can I get banned for using a controller in Fortnite?

No. Epic Games says external devices such as controllers are allowed and won't lead to bans. Epic doesn't test every device, though.

Will my phone fit with its case on?

It depends on the model. Razer promotes the Kishi V3's case compatibility but notes it depends on the combination. With GameSir models, removing the case is usually the safer bet.

Can I use a mobile controller on PC?

The Kishi V3 yes, according to Razer, as a wired controller via USB-C cable. For the other models the makers mainly list Android and iPhone.
