Buying Guide: Which Smartphone Has the Best Fast Charging in 2025?

Not so long ago, battery life was the number one criterion. Things have changed. The real question today is: “How long does it take me to get back to 100 %?”

The 5 p.m. low-battery dread has gone, replaced by a new expectation: a full charge in the time it takes to have a shower.

Two technological empires compete on this ground: SuperVOOC, which powers Oppo, OnePlus and Realme, and HyperCharge, Xiaomi’s answer to it.

Looking for your next smartphone with charging speed high on the list? This guide is for you.

The SuperVOOC world (Oppo / OnePlus / Realme): power kept in check

SuperVOOC’s philosophy has always been to deliver a charge that is not only very fast but also cool. By moving heat management into the charger, the phone stays cool — cool enough that you can game while it charges without losing performance.

The sweet spot: SuperVOOC 80 W

This is the new high-performance standard. It takes you from 0 to 100 % in roughly 30 to 35 minutes. It is the ideal choice if you want blistering speed without going to extremes. Plug the phone in first thing and it is ready before you have finished your coffee.

Outright speed: SuperVOOC 100 W and 120 W

Here we move into pure performance territory. A 0 to 100 % charge often comes in under 25 minutes. This is for people to whom every minute counts. Forgetting to charge overnight stops being a problem: ten minutes gets you more than half a battery.

The Xiaomi HyperCharge world: the race for raw power

Xiaomi takes a different approach, often closer to a show of strength. With HyperCharge the brand has pushed the limits of what is possible, reaching speeds that looked like science fiction two years ago.

Everyday efficiency: HyperCharge 33 W and 67 W

Don’t underestimate these figures. The 67 W in particular is a safe bet, giving a full charge in around 40 minutes. That is far quicker than “standard” charging, and it often comes on phones with outstanding value for money.

The record holder: HyperCharge 120 W

This is Xiaomi’s technological shop window. On some models, 120 W takes you from 1 to 100 % in under 20 minutes. It is fast enough to change the way you use your phone: you stop charging overnight and start topping up in five or ten minute bursts through the day.

Verdict: how to pick your charging champion

As we have seen, SuperVOOC and HyperCharge are not compatible with each other. Choosing your phone therefore commits you to an ecosystem.

So which one?

• If you want balance: if you are after very fast but proven charging that spares the battery by not running hot, the SuperVOOC ecosystem (Oppo, OnePlus) at 80 W or 100 W is an excellent choice.
• If you are always in a hurry: if your only goal is to break records and never see your battery below 50 % again, the raw power of Xiaomi’s HyperCharge 120 W, or SuperVOOC 120 W, is what you want.

Whichever you pick, remember one thing: these speeds are only reachable with the official charger and the official cable.
