How to Check if Your Phone Supports 25W Qi2 Wireless Charging

This guide helps you find out whether your phone can charge at 25W using the Qi2 wireless charging standard. You’ll learn how to identify Qi2 support through official specs, device settings, and physical indicators, and what to do if your phone isn’t compatible.

What You’ll Need

• Your phone (the one you want to check)
• Access to the internet (for checking official specs)
• A Qi2-certified wireless charger (optional, but useful for testing)
• A pen and paper or a notes app to record findings

Step-by-Step

1. Check your phone’s official specifications. Go to the manufacturer’s website (e.g., Apple, Samsung, Google) and look up your exact model. Find the section on charging or wireless charging. Look for the term “Qi2” or “Magnetic Power Profile” (MPP). A phone that supports Qi2 will explicitly list it. If it only says “Qi” without a version number, it’s likely not Qi2.
2. Look for the Qi2 logo on the box or in the manual. If you still have the original packaging, check for a small Qi2 logo (a stylized “Q” with a “2” or the words “Qi2 Ready”). The manual may also mention it under specifications.
3. Check your phone’s settings menu. On many phones, you can find wireless charging information in Settings > Battery > Charging (or similar). Look for options like “Wireless charging speed” or “Fast wireless charging.” If it mentions “Qi2” or “25W wireless charging,” that’s a strong indicator. If it only says “Fast wireless charging” without a wattage, it may not be Qi2.
4. Inspect the back of your phone for a magnetic ring. Qi2 chargers use magnets to align perfectly with the phone’s internal coil. If your phone has a visible magnetic ring (often a circular outline) on the back, it’s likely Qi2-compatible. However, some phones hide this under the glass, so this is not definitive.
5. Try a Qi2-certified charger (if you have one). Place your phone on a Qi2 charger. If it snaps into place magnetically and starts charging, it supports Qi2. If it doesn’t align magnetically and only charges when you position it manually, it’s not Qi2.
6. Check for a 25W charging capability in the specs. Even if a phone has Qi2, it may not support 25W. Look for the maximum wireless charging wattage. If the specs say “15W wireless charging” or “25W wireless charging,” note that Qi2’s default is 15W; 25W is an extension that some manufacturers implement. A phone that says “25W Qi2 wireless charging” is what you’re looking for.
7. Use a third-party spec database. Websites like GSMArena or Kimovil list detailed specs for most phones. Search your model and check the “Charging” section. They often note “Qi2” and the exact wattage.

Common Mistakes

• Confusing Qi with Qi2. Qi is the older standard; Qi2 is the new one with magnetic alignment. A phone that only supports Qi won’t work with Qi2 chargers at full speed.
• Assuming all Qi2 chargers deliver 25W. Qi2’s baseline is 15W. 25W is an optional extension. Your phone must specifically support 25W Qi2, and you need a charger that also supports 25W.
• Relying on the charger’s label. A charger may say “25W” but only deliver that to a specific phone brand. Check both the phone and charger specs.
• Thinking a magnetic case means Qi2. Some cases have magnets but the phone itself may not support Qi2. The phone’s internal coil must be Qi2-certified.
• Ignoring regional variations. Some phone models sold in different regions may have different wireless charging capabilities. Always check the exact model number (e.g., SM-S928B vs. SM-S928U).

Tips

• Look for the “Qi2 Ready” badge. Some manufacturers advertise this on their product pages.
• Check the Wireless Power Consortium (WPC) website. They maintain a list of Qi2-certified devices. You can search for your phone model there.
• If you’re buying a new phone, check the specs before purchase. As of 2025, many flagship phones from Apple, Samsung, and Google support Qi2, but not all. The iPhone 15 and later have Qi2, and several Android flagships do too.
• Use a charging speed tester app. Apps like “Ampere” or “AccuBattery” can show you the charging current. If you have a Qi2 charger, you can see if the phone is pulling more than 15W (roughly 3A at 5V). This is a practical test.
• Keep your phone updated. Sometimes a software update adds Qi2 support to a phone that was initially released without it. Check for system updates.

Troubleshooting

If you’ve followed the steps and still aren’t sure, here’s what to do:

• Your phone doesn’t have a magnetic ring but you think it should. Some phones have the magnets inside the case, not on the phone. Try a Qi2 charger with a compatible magnetic case. If it still doesn’t attach, your phone likely doesn’t support Qi2.
• You find conflicting information online. Trust the manufacturer’s official website over third-party sites. If they don’t mention Qi2, it’s probably not supported.
• Your phone charges but slowly on a Qi2 charger. This could be a charger issue (not delivering 25W) or a phone limitation (only supports 15W). Check the charger’s output specs and your phone’s maximum wireless charging rate.
• You can’t find your phone model in the WPC database. The database may not be up-to-date. Try contacting the manufacturer’s support chat or social media account to ask directly.
• Your phone is older (pre-2023). It’s very unlikely to support Qi2. The standard was only finalized in 2023, so older phones almost certainly don’t have it.

Frequently Asked Questions

What is the difference between Qi and Qi2?

Qi is the original wireless charging standard that uses electromagnetic induction. Qi2 adds a magnetic alignment profile (MPP) that ensures the charging coil in the phone aligns perfectly with the charger’s coil, improving efficiency and enabling faster charging (up to 15W baseline, with extensions like 25W).

Do all Qi2 phones support 25W charging?

No. The Qi2 standard’s baseline is 15W. 25W is an optional extension that some manufacturers implement. Your phone must specifically state that it supports 25W Qi2 wireless charging.

Can I use a Qi2 charger with a non-Qi2 phone?

Yes, but it will charge at the phone’s maximum wireless charging speed (usually 5W or 7.5W) and won’t have magnetic alignment. It may still work, but you’ll need to position the phone carefully.

How can I tell if my charger is Qi2-certified?

Look for the Qi2 logo on the charger or its packaging. You can also check the WPC’s certified products list. A charger that says “Qi2” but isn’t certified may not deliver the promised speeds.

Is 25W wireless charging safe for my phone battery?

Yes, if your phone is designed for it. The phone’s internal battery management system regulates the charging speed to prevent overheating and overcharging. Using a certified Qi2 charger with your specific phone model is safe.

My phone supports Qi2 but not 25W. Can I get 25W with a special charger?

No. The phone’s hardware must support the higher wattage. A charger can’t force more power into a phone that isn’t designed to accept it. You’ll get the phone’s maximum supported wireless charging speed, which is typically 15W for Qi2.
