Samsung Galaxy S24 Ultra Charging Speed @ 15W, 25W, 45W!

Spread the love

Take a look at the battery charging speed of the Samsung Galaxy S24 Ultra, and find out how fast you can recharge with the official 15W, 25W and 45W chargers!

 

Samsung Galaxy S24 Ultra Supports Up To 45W Charging!

The Samsung Galaxy S24 Ultra supports up to 45 watts of wired fast charging, but unfortunately, does not come with the charger in-the-box. You can either use the standard 15 watt fast charger from your previous Samsung smartphone, or purchase a 25 watt or 45 watt super fast charger.

Best To Use Samsung Fast Charger

You can use non-Samsung fast chargers, but while they may charge your Galaxy S24 Ultra, they will likely not charge at full speed.

For example, I tested the Galaxy S24 Ultra using 65W and 96W PD fast chargers, but they failed to charge faster than 25 watts. It would only charge beyond 25 watts with an official Samsung 45W fast charger… 🙁

How To Tell If You’re Charging At Full Speed

The Samsung Galaxy S24 Ultra doesn’t make clear how fast you are charging, so how do you know if you are charging fast enough?

When you plug in the charger, the charging protocol will flash for a few seconds on the display of your Galaxy S24 Ultra:

  • Fast charging : you’re charging at up to 15 watts
  • Super fast charging : you’re charging at up to 25 watts
  • Super fast charging 2.0 : you’re charging at up to 45 watts

How To Activate Fast Charging

The Samsung Galaxy S24 Ultra has fast charging enabled by default. But if you are using a Samsung fast charger, and it somehow isn’t charging at full speed, here is how you can verify if fast charging is enabled.

  • Go to Settings > Battery > Charging settings
  • Make sure Fast charging is enabled.
    If not, tap on Fast charging to enable it.

Please note that this setting cannot be changed while the Galaxy S24 Ultra is charging. You will need to pull out the cable before making any changes.

You Must Use Correct Cable

Samsung fast charging protocols also require you to comply with minimum cable requirements:

  • 25W super fast charging : 3A cable minimum
  • 45W super fast charging 2.0 : 5A cable minimum

The Galaxy S24 Ultra comes with the Samsung EP-DN980, which is USB-C to USB-C cable that supports up to 5A of current. So this cable will readily support 45W charging.

Samsung Galaxy S24 Ultra Charging Speed @ 15W, 25W, 45W!

 

Samsung Galaxy S24 Ultra Charging Speed @ 15W, 25W, 45W!

We tested the Galaxy S24 Ultra using the official 15W, 25W and 45W Samsung fast chargers, and the results are really surprising!

Galaxy S24 Ultra Charging Time Charging Speed
15 Watts 106.5 minutes 37.6 mAh per min.
25 Watts 68 minutes 58.8 mAh per min.
45 Watts 66 minutes 60.6 mAh per min.

The Samsung Galaxy S24 Ultra charges really fast with a 15 watt charger, and even faster with a 25 watt charger. It basically needs just over 1.75 hours to fully recharge with a 15 watt charger, and just over one hour with a 25 watt charger.

Unfortunately, upgrading to the 45 watt charger doesn’t improve its charging speed much. It only shaved 2 minutes off the charging time with a 25 watt charger!

In fact, that’s actually its best time. On two other occasions, it charged slower than the 25 watt charger! Really quite unexpected.

Just in case you are wondering – it does charge at 45 watts, but only at the beginning for a short time. After that it charged at between 12 watts to 24 watts for most of the charge.

With such results, I can only recommend purchasing the optional 25 watt USB-C super fast charger. It will cut your charging time by a considerable 38.5 minutes for a full recharge:

Don’t bother getting the 45 watt charger, unless you want to recharge your laptop, or power bank at a faster speed.
