I used 15W to 18W is more than sufficient for me. 25W or 33W is good to settle. Don't go beyond unless battery tech is improved.

    33W is perfect!! I have 2 phones in family with 5000 mAh battery (Poco X3 Pro & Realme 8S). Both charge in 60-65 min to a full 100% charge.

      I really like the 33 Watt charger that was included in the Redmi Note 10S and I only charge my phone to 80-90% because based on some research charging up to 80% can extend the life of a lithium battery.

        Honestly just want a proper big battery in a compact-ish phone - charging around 30W is fine for me. Would easily take 2 day battery life over crazy fast charging - charge it overnight every other day.

        But yes, for decently fast top ups I would still like 30W.

          Between 25 and 67 is the sweet spot imo
