Latest round of Galaxy S23 leaks: brighter screens, bigger batteries and improved cooling

Written by admin

As 2022 slowly but surely draws to a close, the eyes of all tech enthusiasts are now firmly on 2023 – and the latter will start with a bang. The launch of the Samsung Galaxy S23 (reportedly due February 1, 2023) is fast approaching.

Expect (many) more leaks in the coming weeks

A few days ago we saw some of the first official promotional images of Samsung’s flagship for 2023. This implies two important things. First, it gives credence to the fact that the launch is indeed imminent. In the event that Samsung is already sending promotional material, an announcement should be just around the corner. Secondly, it means we can expect a massive flurry of additional leaks in the coming weeks. Judging by recent history, many media partners receive exclusive information that is occasionally leaked online once the launch event is officially scheduled. In all likelihood, the Samsung Galaxy S23 series will suffer the same fate.

Once that happens, there is almost no room for surprises and all details surrounding the Samsung Galaxy S23 can pretty much be officially confirmed. Before that happens, though, we have a few new bits of (unofficial) information that we think are very likely to be true.

Bigger batteries and brighter screens. S23 Ultra misses the upgrades

Today, 2 new leaks have been exposed by @IceUniverse, a prolific Samsung tipster, with an impeccable track record. The information was shared through his officer Weibo account. It was subsequently further corroborated by other less prominent sources. The first leak concerns the battery specifications of the S23 family. According to IceUniverse, both the Galaxy S23 and The Galaxy S23+ gets minor upgrades to the 200mAh battery capacity. The However, the S23 Ultra will have the same battery capacity as last year’s model.

Additionally, the Galaxy S23+ and the S23 Ultra support 45W wired fast charging, while the smaller vanilla S23 is still stuck at just 25W. A detailed breakdown and comparison is available below.

* Preliminary information; Upgrades are in bold

The second leak claims that the S23 will receive an increase in peak brightness levels – the display of the smallest S-series smartphone should now max out at 1750 nits. For reference, the current Galaxy S22 has a maximum brightness of only 1300 nits.

It should be noted that the Galaxy S22 Plus and the The Galaxy S22 Ultra already has a maximum brightness of 1750 nits. Therefore, this is a significant upgrade that brings the vanilla S23 in line with its bigger siblings.

Improved cooling systems

It’s hardly a secret that the Galaxy S series has struggled with thermals in the past. This is one of the reasons why it sometimes fails to reach the peak performance that the lineup is aiming for. Fortunately, Samsung has been working on a solution and it may finally be here. According to a source, the entire Galaxy S23 family will be equipped with improved cooling systems. The leak was first brought to light by Ahmed Qwaiderand was subsequently covered by Sammobile in an article.

According to Qwaider, Samsung “addressed this point significantly during heavy use”. The thermal performance optimisation, coupled with the overclocked Snapdragon 8 Gen 2 chipsets that the S23 is reportedly debuting with, will add up quickly and likely deliver a very powerful flagship.


This all sounds promising on paper, but nothing is set in stone at this point. Amidst all the hype and leaks, it is possible for misinformation to emerge. Still, by most accounts, the Galaxy S23 is on the horizon and we’ll be able to put it to the test sooner rather than later.
