The reliable test is the Wireless Power Consortium (WPC) Certified Products Database. Find your phone’s exact model identifier, open the matching WPC record, and verify that it is a phone receiver certified for Qi2 25W (identified by WPC as Qi v2.2.1). A phone that merely says “Qi,” “Qi2,” or “wireless charging” is not proven to accept 25W. Check the charger as a separate certified product, because a 25W charger cannot turn a lower-power phone into a 25W receiver.
What “25W Qi2” actually means
Wireless charging labels describe different generations and roles. Qi is the broad wireless-power standard. Qi2 is a newer generation that uses magnetic attachment to align a compatible device and charger. WPC’s standard overview describes original Qi2 as a 15W tier and identifies Qi v2.2.1 as Qi2 25W, a newer, higher-power tier.
| Label or claim | What it establishes | What it does not establish |
|---|---|---|
| Qi certified | The product passed a Qi certification process at the profile recorded by WPC. | That it supports magnetic Qi2 alignment or 25W input. |
| Qi compatible, Qi compliant, or “Works with Qi” | A manufacturer compatibility claim. | That WPC tested and certified the product, or that it accepts 25W. |
| Qi2 | Support for the Qi2 generation at the certified power profile. | That the receiver is in the Qi2 25W tier rather than the original 15W tier. |
| Qi2 25W / Qi v2.2.1 | The specific higher-power receiver or transmitter profile you are looking for. | That every charger, adapter, case, temperature, or usage condition will deliver 25W continuously. |
| 25W printed on a charger | The charger or transmitter is advertised as capable of that output under its requirements. | That the phone can receive 25W wirelessly. |
WPC says Qi2 25W provides nearly 70% more charging power than original Qi2 and gives an example of charging a smartphone from 0% to 50% in about 30 minutes. Those are WPC’s standard-level figures, not a guarantee for every phone. Battery size, adapter capacity, temperature, case design, alignment, software limits, and simultaneous use can change the result. The figures describe the charging system under suitable conditions, not a promise that your phone will always draw exactly 25 watts.

Step 1: Identify the phone precisely
Start with the identifier printed in the phone’s settings or on its packaging, not the name used in an advertisement or a retailer’s headline. A single family name can cover several generations, storage configurations, carrier editions, and regional variants.
- Open the phone’s settings and look for an “About phone,” “Device information,” or similarly named screen.
- Record the manufacturer, complete model name, model number, and manufacturer part number if shown. Copy punctuation, suffixes, and regional characters exactly.
- Compare that information with the label on the box and the manufacturer’s support page. If they disagree, use the identifier tied to the physical device and ask the manufacturer to resolve the discrepancy.
- Note whether the phone relies on a separate magnetic case or other accessory for alignment. That matters because a Qi2 Ready receiver can have an accessory-specific certification condition.
Do not substitute a series name for a model number. “Pro,” “Ultra,” “Plus,” carrier suffixes, and regional codes may refer to different certified products. The database record must identify the phone you own.
If you are comparing phones before purchase, copy the exact part number from the manufacturer’s specification or ask support for it. Do not assume that two phones sold under one family name share a receiver certification. The same caution applies when importing a regional variant: a familiar retail name is not enough to establish that its WPC entry is identical.

Step 2: Search the WPC Certified Products Database
Search the WPC Certified Products Database using the exact model identifier. WPC’s own guidance says: “To be certain that a product has been tested to Qi certification standards, search for it in our database.” The database is a live catalogue, so records can be added or changed after a phone launches.
- Search first for the complete manufacturer part number. If there is no result, try the exact model name, then a distinctive portion of the identifier while retaining the manufacturer filter.
- Review every plausible result rather than selecting the first item. A phone can appear beside chargers, stands, battery packs, or earlier versions with similar names.
- Open the product record and compare its brand, product name, manufacturer part number, product type, power profile, Qi version, and certification date with your phone.
- Confirm that the product type is a receiver or phone. A transmitter record describes a charger, not the phone’s ability to accept power.
- Save the record details for your model and region. Certification dates and database entries can change, so retain the exact identifier when contacting support.
A search result that matches only the brand or family name is not enough. If two regional variants have different part numbers, treat them as separate products until the manufacturer or WPC record confirms they share certification.
Search results can contain both receiver and transmitter products from the same manufacturer. Read the role field rather than inferring it from a product photograph. A flat charging pad, stand, or puck is normally a transmitter listing; the handset needs its own receiver entry. If the database offers filters for product type, use them, but still open the record and inspect the identity fields.
How to read a matching WPC record
Product identity
The record’s brand, product name, and manufacturer part number should describe the same physical phone. “Similar” is not a sufficient match: a charger from the same brand, a previous generation, or a different regional edition does not certify your handset.
Product type and role
Wireless systems have a receiver (the phone) and a transmitter (the charger). The database can list both. A transmitter certified for 25W proves the charger was tested for that profile; it does not prove that your phone’s receiver accepts 25W. Verify the receiver record independently.
Qi version and power profile
Look for the entry that corresponds to Qi2 25W, which WPC identifies with Qi v2.2.1. A record that says only Qi, a generic wireless-power profile, or original Qi2 does not establish 25W reception. The original Qi2 level described by WPC is 15W.
Certification date
Use the date to distinguish a newer 25W certification from an older record for the same product. It also tells you which database information you saw when making the decision. A historical listing is useful evidence, but current compatibility should be checked against the live record and the manufacturer’s latest specification.
Certificate link and identity check
If a manufacturer sends a certificate URL, open it and compare the WPC page with the handset’s exact identity. WPC says a valid certificate URL should lead to a WPC page showing the same product identity. A link that opens a generic brand page, a charger entry, or a different part number does not settle the question. Save the URL and the record date if you need to contact support again.
Check the charger as a separate product
After verifying the phone, search for the charger’s exact model number in the same database. Confirm its product type is a transmitter and that its certified profile corresponds to Qi2 25W. Then check the charger maker’s electrical requirements for the power adapter and cable. A transmitter may need an adapter with sufficient wattage and a particular USB-C power capability; using a weaker adapter can reduce output even when the charger itself is certified.
Keep the two conclusions separate:
- Phone receiver: certified for Qi2 25W, or not.
- Charger transmitter: certified to provide Qi2 25W, or not.
- Complete setup: capable of the phone’s certified rate only when the charger, adapter, cable, alignment, case, temperature, and software conditions all permit it.
If either the phone or the charger is limited to an earlier Qi profile, the setup will operate at the lower negotiated rate. The larger number printed on one component does not override the certified limit of the other.

When comparing chargers, use the certified model number, transmitter role, Qi version, power profile, certification date, included adapter requirements, and any approved-accessory condition as your comparison axes. Price or a prominent wattage badge cannot replace those checks. The WPC database does not turn a charger’s advertised maximum into a guarantee for every connected phone.
Understand “Qi2 Ready” and accessory requirements
Some receivers are certified as “Qi2 Ready.” WPC’s logo guidance says a Qi2 Ready receiver must be used with the specific approved accessory with which that receiver was tested and certified. The accessory may provide magnetic alignment that is not built into the phone itself.
- Find the Qi2 Ready receiver record for the exact phone model.
- Read the certification documentation for the named approved accessory or accessory family.
- Match the accessory’s model and revision, not merely its general description as a magnetic case.
- Use the approved accessory when testing or relying on the Qi2 25W claim.
A generic magnetic case can hold a phone near a charger, but it does not automatically create a certified Qi2 25W system. If the WPC record names an accessory, an unlisted case leaves the certification condition unverified.
Do not confuse “magnetic” with “Qi2 Ready.” Magnetic rings and cases can differ in position, thickness, and construction. Only the accessory named in the receiver’s certification documentation satisfies the tested condition described by WPC. If no accessory is named, check whether the phone has integrated magnetic alignment or ask the manufacturer for the exact setup required.
What to do when the model is missing or ambiguous
An absent or confusing result is a reason to pause, not to infer compatibility from the phone’s appearance or brand.
No result for the exact part number
Repeat the search with the exact model name and manufacturer, checking spelling and regional suffixes. If the phone still does not appear, ask the manufacturer for the WPC certificate or a model-specific statement that identifies the receiver’s Qi version and power profile.

Compare the manufacturer part number, product type, certification date, and regional designation. Select the record that matches all four. If one field cannot be reconciled, request clarification rather than treating the closest result as proof.
A manufacturer page says “25W” but has no matching record
Ask support for the exact WPC certificate URL or certificate identifier and the corresponding phone part number. WPC explains that a valid certificate URL should lead to a WPC page showing the same product identity. Marketing language alone is weaker evidence than a matching database record.
The phone appears only as a general Qi product
That establishes, at most, the profile shown in that record. It does not establish Qi2 25W. Ask whether a separate Qi v2.2.1 receiver certification exists for your exact model or whether the published claim refers only to a charger or accessory.
The record is old or the phone has a revised variant
Check the certification date and part-number suffix, then search the current database again. Certification is a changing fact. A record for an earlier hardware revision should not automatically be applied to a later regional or carrier version.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesWhy a 25W setup may still charge below 25W
Certification identifies a product profile; it does not promise a constant meter reading during every session. Charging power can fall when the battery approaches a high state of charge, the phone is warm, the screen or processor is busy, alignment is imperfect, or the case adds distance between coils. The adapter, cable, and charger may also impose limits.
- Center the phone on the charger’s magnetic alignment point.
- Remove thick, metallic, damaged, or unapproved cases while troubleshooting.
- Use the adapter and cable specified for the transmitter.
- Let a hot phone cool before judging performance.
- Test with the screen idle and no demanding app running.
- Compare the result only after the phone and charger have negotiated a stable connection.
These steps can explain a lower observed rate, but they cannot upgrade a non-25W receiver. If the WPC record identifies the phone as 15W Qi2 or another profile, the lower limit is expected. A single short test is also not a certification test: repeat it under the same conditions and rely on the product records for the supported profile.
Common claims that do not prove Qi2 25W support
“It sticks magnetically, so it must be 25W”
Magnetic attachment indicates a physical alignment feature, not a particular certified power profile. Verify the receiver record and Qi version.

“The phone supports wireless charging”
General wireless charging can refer to an earlier Qi generation or a lower power level. It does not identify Qi2 25W.
“Qi2” is printed on the box
Original Qi2 is described by WPC as 15W. Confirm that the record specifically identifies Qi v2.2.1 or Qi2 25W.
“Qi compatible” or “Works with Qi” appears in a listing
WPC warns that these phrases do not prove certification. Use the WPC database and certificate instead.
A retailer lists one wattage for the whole bundle
A bundle can contain a transmitter, adapter, case, and phone with different limits. Separate each model, identify its role, and verify the receiver and transmitter records independently.
How general phone-support pages fit into the check
Google’s general Pixel support guidance says wireless charging is available on Pixel 3 and later with exceptions and advises checking that a case is compatible with Qi2. That page is useful for general device and case guidance, but it is not a model-by-model Qi2 25W certification list.
Samsung’s wireless-charging troubleshooting guidance likewise covers wireless charging generally and advises checking non-Samsung chargers with the manufacturer or WPC. It does not, by itself, establish that a particular Samsung model is a Qi2 25W receiver. For either brand, use the exact model’s WPC record and request model-specific confirmation when the record is unclear.
Brand support pages can help you locate the model number, understand case restrictions, or troubleshoot a failed charge. They should supplement—not replace—the WPC record for a 25W certification decision.
A printable decision checklist
- Do I have the phone’s complete model name and manufacturer part number?
- Does the WPC record match that identity and the correct regional variant?
- Is the record a phone receiver rather than a charger transmitter?
- Does it specify Qi v2.2.1 or Qi2 25W, rather than generic Qi or original 15W Qi2?
- Does it name a required Qi2 Ready accessory?
- Is the charger separately listed as a certified Qi2 25W transmitter?
- Does the charger’s adapter and cable meet its stated requirements?
- If any answer is unknown, have I obtained a certificate or model-specific statement from the manufacturer?
What the certification history tells you
WPC’s July 23, 2025 launch release described an initial limited certification launch involving 14 certified devices, including receivers and transmitters. That number was a snapshot of the launch, not a permanent count or a complete list of phones. The database is the authoritative place to check later additions and revised records.

Questions readers commonly ask
Does a 25W Qi2 charger make any compatible phone charge at 25W?
No. The phone must itself be a WPC-certified Qi2 25W receiver. The charger’s output rating cannot upgrade a lower-power receiver; the negotiated result is constrained by the lower certified capability.
Is original Qi2 the same as Qi2 25W?
No. WPC describes original Qi2 as 15W and identifies Qi2 25W with Qi v2.2.1. A listing that says only “Qi2” needs a database check to determine which tier it represents.
Can a magnetic case add Qi2 25W support?
Only when the phone is certified as Qi2 Ready for that specific approved accessory. A generic magnetic case is not proof of certification and may not match the tested alignment condition.

What if my phone supports wireless charging but has no Qi2 25W result?
Treat it as unsupported for 25W until the manufacturer provides a matching Qi v2.2.1 receiver certificate or a model-specific statement that can be verified against WPC’s records.
Should I check the charger or phone first?
Check the phone’s exact identity first, then search the charger separately. Both records are required for a complete 25W setup.
Does a case advertised as Qi2-compatible prove the phone is Qi2 25W?
No. Case marketing does not establish the handset’s receiver certification. If the phone is Qi2 Ready, use the exact accessory named in its WPC documentation.
Can I rely on a phone family name or a retailer specification?
Not by itself. Family names can hide regional and hardware differences, and retailer shorthand may collapse receiver and transmitter claims. Match the complete part number in the WPC database.
Why does my certified setup show less than 25W?
Heat, battery state, alignment, case thickness, adapter capacity, cable limits, software controls, and active phone use can reduce the instantaneous rate. Certification does not promise a constant reading.
Is there a complete list of 25W Qi2 phones?
Do not rely on a static brand list. WPC’s database changes as products are certified, and the primary guidance does not provide a permanent exhaustive phone list. Search the exact model currently.
Frequently Asked Questions
Does a 25W Qi2 charger make any compatible phone charge at 25W?
No. The phone must itself be a WPC-certified Qi2 25W receiver; the charger’s output rating cannot upgrade a lower-power receiver.
Is original Qi2 the same as Qi2 25W?
No. WPC describes original Qi2 as 15W and identifies Qi2 25W with Qi v2.2.1.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Can a magnetic case add Qi2 25W support?
Only when the phone is certified as Qi2 Ready for that specific approved accessory. A generic magnetic case is not proof of certification.
What should I do if my exact phone model is missing from the WPC database?
Search again using the complete model name and manufacturer, then ask the manufacturer for a WPC certificate or model-specific Qi v2.2.1 receiver statement. Do not infer support from the brand or charger.
Do I need to certify the charger separately?
Yes. Verify the charger as a Qi2 25W transmitter and check its adapter and cable requirements. Phone and charger certification are separate.
Does a retailer’s “Qi compatible” label prove 25W support?
No. WPC says phrases such as “Qi compatible,” “Qi compliant,” and “Works with Qi” do not prove that the product was certified. Use the WPC record.
Why can a certified phone charge below 25W?
Charging power varies with temperature, battery state, alignment, case design, adapter and cable capacity, software limits, and active use. The 25W certification is not a promise of a constant meter reading.
Is there a permanent list of every Qi2 25W phone?
No static list should be treated as definitive. Certification records change, so search the live WPC database for the exact model and regional variant.
The Bottom Line
To verify 25W Qi2 support, match your exact phone part number to a WPC receiver record that identifies Qi v2.2.1, then verify the charger separately as a certified Qi2 25W transmitter. If the record is missing, ambiguous, or accessory-dependent, obtain the manufacturer’s model-specific certificate or compatibility statement before relying on the claim.
