Samsung Galaxy S23 Ultra Charging Speed

However, Samsung hasn’t particularly made any real progress in charging technology. So a fair question in the mind of all potential buyers is, how quickly does the Galaxy S23 actually take to charge? Samsung’s charging tech is based on the USB Power Delivery specification, so you can rely on third-party chargers that support the standard. However, note that these numbers only indicate the maximum power that the phone will accept in ideal conditions.

When the phone actually starts charging, it accepts a number lower than the maximum, depending on factors like the battery percentage and ambient and device temperatures. Samsung’s charging situation with predecessor devices has not been great, as devices like the Galaxy S21 series and Galaxy S22 series barely maintained their peak wattage for fleeting moments, choosing to settle instead on a slower wattage for the vast majority of the charging cycle. Since the phones did not have very high peaks to begin with, the end result was that the devices charged rather slowly. Charging Standard Samsung Galaxy S22 Ultra Samsung Galaxy S23 Ultra Charging Standard 45W USB Power Delivery PPS The difference between the two devices is not that impressive, but considering the fact that the underlying spec sheet did not change between the two devices, there are some algorithmic improvements that Samsung did bring to the table, allowing for a better charging curve. As you can see in the graph above from our test data, the Galaxy S23 Ultra accepted 45W-40W of power for as much as five minutes, which is a big improvement from the Galaxy S22 Ultra which barely touched 40W for a minute. The Galaxy S23 Ultra also sustains the higher wattage acceptance for longer. The lead narrows on the latter half of the charging cycle as the S23 Ultra has a sharper drop-off, but it still manages to stay the winner.

The Galaxy S23 Ultra’s 57 minutes of charging time for its 5,000mAh battery looks impressive when you compare it to some key rivals. Our first recommendation remains the official Samsung charger, but that can be a bit expensive for many people. Thus, for users exploring a more cost-effective solution, we recommend the Tecknet 45W Dual USB-C charger.

The standard Galaxy S23, which tops off at 25W, averaged 80 minutes to charge to full.

That’s a pretty significant difference, but not too bad compared to the likes of the Pixel 7 or iPhone 14. The Galaxy S23 Plus takes 55 minutes to charge its 4,700 mAh battery with an advertised 45W of power.

The Tecknet 45W Dual USB-C charger is the second choice, as it comes out on top with its low pricing and versatility. If you want something with a USB-C and a USB-A port, then you can opt for the Iniu 30W USB PD charger as our third recommendation.

As expected, these are fairly expensive compared to the third-party Qi-compatible charging options. The exact times that you will get will vary depending on the ambient temperature, your placement on the wireless charger, and your starting battery percentage. Note that the wireless charger is a bit expensive compared to third-party alternatives. However, we can’t help but marvel at the ludicrous charging speeds that Chinese OEMs provide on their phones.

There’s some debate on how extremely fast charging can cause rapid battery deterioration, but OEMs claim that their recent releases perform better on this end. Couple the battery degradation worries with the unfortunate saga of the Galaxy Note 7, and we can see why Samsung would play it extremely cautiously. Still, we’d love to see them take full advantage of the 45W USB PD PPS charging, at least for future devices. Anything beyond that point starts venturing into overkill territory, and we’ll prefer the cautious and conservative approach beyond that number.

No, Samsung does not include a charging brick in the box of any of the Galaxy S23 series devices. However, these proprietary wireless chargers are relatively expensive, so weigh your decision appropriately.

Samsung Galaxy S23 Ultra’s 45W fast charging is actually fast this time

This meant we had to deal with handsets with mostly solid battery life but whose cells refill barely any faster than they did when charging at the older power levels. Previous models still took about an hour or longer to charge, which is hardly that fast in the context of the broader smartphone market. With new handsets hitting the market, it’s time to test the Galaxy S23 Ultra charging speed and power to see if that situation has improved. For comparison, we also tested a selection of other models that support different power levels and protocols.

The key takeaway is that the Galaxy S23 is a little bit faster to charge than its predecessor, provided you pick the right charger. We retested the phone with the latest OneUI 5 software to confirm the handset still offers the same performance as we noticed at launch.

Samsung has improved the Galaxy S23 Ultra’s fast charging capabilities, with high power levels sustained for longer. In a nutshell, the Samsung Galaxy S23 Ultra spec sheet may look the same as its predecessor, but it offers improved sustained charging performance and, therefore, faster top-ups.

Just another hidden, under-the-hood change that really helps to refine Samsung’s classic Galaxy formula in 2023. If you’re looking for the best charger for your Galaxy S23 series smartphone, you’re probably wondering if Samsung’s 45W charging adapter makes sense. However, you do shave a few minutes off charging time if you pair a 45W adapter with a Galaxy S23 Ultra or S23 Plus. You can use any adapter that supports this standard, as long as it provides enough power; 25W for the base model or 45W for the Plus and Ultra.

Samsung Galaxy S23 Ultra battery life and charging speed results

The Galaxy S23 Ultra beats the endurance rating of its predecessor by 18 hours. But even more than that – the Galaxy S23 Ultra is competitive against the Apple iPhone 14 Pro Max – something Samsung’s big phones haven’t been able to do for years. It’s still technically capped at 45W, though we did see an improvement in charging speed compared to the Galaxy S22 Ultra.

Galaxy S23 Ultra charges slightly faster in the first 30 minutes

The Galaxy S23 series brings a lot of subtle improvements, but a charging power upgrade isn’t one of them. The Galaxy S23 Ultra charges fully in 59 minutes when using a 45W USB PD 3.0 charger with PPS (Programmable Power Supply). Since the Galaxy S23 Ultra has a much bigger heat dissipation solution, it can cool down more efficiently, leading to slightly faster charging speeds.

Pros Very good autonomy at nearly 67 hours in moderate use

Excellent autonomy when watching videos Low discharge currents overall, especially when streaming videos and calling Low residual power drain when the device is fully charged and still plugged in Cons Battery level collapses after 5%

Low autonomy when using the camera or listening to music High residual consumption of the wireless stand The Samsung Galaxy S23 Ultra battery experience earned an excellent global score, placing it among the top 10 devices we have tested so far and in the top spot of our Ultra-Premium segment.

Powered by Qualcomm’s Snapdragon chipset, the Galaxy S23 outperformed its predecessor, the Samsung Galaxy S22 Ultra (both the Snapdragon and Exynos versions) by a long stretch, thanks to better autonomy and efficiency scores. The Samsung Galaxy S23 Ultra showed excellent results in our autonomy tests. The battery lasted nearly 67 hours when used moderately, with less than 2% lost per night on average. When testing outdoors, the performances were also very good, except when using the camera, where the autonomy was slightly below our database average. During the tests where we evaluate particular usages separately, the autonomy was excellent, too, especially when streaming videos.

However, the battery level collapsed when reaching 5%, which could impact the user experience. The Galaxy S23 Ultra’s charging results were average, whether wired or wireless. The time to fully replenish the battery with a wired charger took 1 hour and 21 minutes, and with a wireless one, 2 hours and 18 minutes. A quick 5-minute wired charge provided a good 5 hours and 23 minutes of autonomy on average, but the autonomy recovered when charging from 60% was only half of what was recovered when charging from 20%.

The residual consumption for both wired and wireless chargers was very low when the device is fully charged and still plugged in. However, the residual consumption of the wireless stand itself was very high, placing it at the bottom of the database.

In almost all test cases (except music streaming and idle with screen off), the discharge currents were very low, meaning that the device is well-optimized. Flagship devices often face challenges in battery performance because of their power-hunger new features.

This is where careful hardware and software integration plays a significant role in battery performance. Compared with other devices from the Ultra-Premium segment ($800+), the Samsung Galaxy S23 Ultra easily reached the top score of our database. Even if it did not set any new highs in the sub-scores, its excellent autonomy and efficiency, combined with a good charging experience, allowed the Galaxy S23 Ultra to obtain the best score so far for this segment.
