The Rise of Mobile Gaming: More than Just Casual Fun
Over the past decade mobile gaming has evolved a lot. What once began with simple puzzle games like Candy Crush or Flappy Bird, has expanded to be an industry where people are now playing open world adventures, or complex multiplayer shooters. Today, mobile gamers expect real-time performance, console quality visuals, and responsive controls. Games like Call of Duty Mobile, Genshin Impact and PUBG Mobile make the devices work at their limit.
Another genre that has taken off in a serious way is online casino gaming. These games offer digital versions of traditional games such as poker, blackjack, and pokies, with modern graphics, sound effects and interactive features. A category that stands out in this space is online pokies, in Australia especially. These are virtual slot machines, often with different themes, payout structures, and styles of play. For those unfamiliar with how these games work or which ones are worth trying, they can check the CryptoNews list of best online pokies in Australia, which offers a helpful overview.

Specs on Paper: Does the Galaxy S25 Ultra Have the Firepower?
Let’s go into specs, because that’s where the real story begins.
- Processor: The Galaxy S25 Ultra comes with the new Snapdragon 8 Elite chip. This chip is designed for heavy multitasking and gaming.
- RAM & Storage: It comes with up to 16GB RAM and 1 TB internal storage. That’s more than enough for even the largest mobile titles.
- Display: A Dynamic LTPO AMOLED 2X screen with 120Hz refresh rate and ultra-low latency make everything look fluid and vibrant.
- Cooling System: Samsung has upgraded the vapor chamber cooling tech in the S25 Ultra to ensure the phone doesn’t overheat during long gaming sessions.
- Battery: A 5,000mAh battery is combined with power optimization to ensure users get hours of uninterrupted gaming.
Now, specs aren’t everything, but they do give us a good idea of how good the phone should be.
Galaxy S25 Ultra Performance and High End Games
Details don’t tell the whole story, and this is especially true when it comes to gaming. What is important is how a device will react under the stress of actual gameplay. With its high-end internals, Galaxy S25 Ultra is well-equipped to handle even the most demanding mobile games that can often push the boundaries of smartphones.
Games such as Genshin Impact, Call of Duty Mobile, and Diablo Immortal require advanced GPU performance, fast touch response, and smooth frame rates for a smooth experience. With its improved chipset, ample memory capacity, and high refresh rate display, the S25 Ultra is set to deliver on these expectations. The improved thermal design also means that it should be good for handling heat for a long session.
Game Mode and Additional Features for the Hardcore Gamers
Samsung has included some features that gamers will like:
- Game Booster Pro: The inbuilt software will increase the performance of the CPU and GPU while lowering the background activity.
- Priority Mode: Stops notifications and incoming calls from interrupting your game.
These features may not appear to be a big deal, but they truly make a difference, especially if you’re keen on grinding through competitive matches without any distractions.
What About Draining and Charging the Battery?
Even a gaming phone needs to have good battery life if it is to be useful. With its massive capacity battery, the Galaxy S25 Ultra is designed to support long gaming sessions. Battery life will always suffer in demanding applications like high refresh rate gaming or graphically intensive applications, but the S25 Ultra appears to be built with that in mind.
It also supports 45W wired and 15W wireless charging which indicates that recharging times should be relatively short. Fast charging can be a big benefit, especially for users who play mobile games for long periods of time and don’t want to wait hours to charge and then start playing again.
