Speed test: Galaxy S9 Plus vs. S8 vs. S8 Plus vs. Note 8

The Galaxy S9 Plus sports the cutting-edge Snapdragon 845 processor, but how much impact does it really have on the phone's performance? We ran the phone, and three other Galaxy devices, through a series of speed tests to find out.

The Galaxy S9 Plus is Samsung’s latest flagship, and arguably its best. In our S9 Plus review, we characterized it as “a statement of best-in-class hardware,” commending the phone for its svelte design and stunning camera capabilities. The S9 Plus also sports a cutting-edge Snapdragon 845 processor, but does that give it a noticeable edge over the other phones in Samsung’s roster?

To find out, we pitted the S9 Plus and three other Samsung phones — the Note 8, S8, and S8 Plus — against one another, allowing us to see which phones could launch a variety of apps and games the quickest. It wasn’t the most rigorous test, but it did provide some insight into the relative power of these different models.

For the test, we opened a host of popular apps — Twitter, Facebook, Pokémon Go, and Super Mario Run, among others — and timed how quickly they launched.

What were the results? Surprisingly, for most apps, the four phones finished in about the same time. The S9 Plus performed the best when it came to Google Maps, and tied for first when launching a few other apps. The S9 Plus was the slowest at opening Facebook and Pokémon Go, however, and clocked in nearly 15 seconds after the S8 when launching the latter. This falls in line with the observations we made in our S9 Plus review, in which we noted the headset’s occasional stutter despite its ability to handle day-to-day tasks with the utmost ease.

How is it possible that the S9 Plus, which has a Snapdragon 845 instead of a last-gen 835, fared so poorly? There are a couple of possibilities. One is that the phone was experiencing issues, such as excessive cached data, which had a direct impact on performance. Another thing to consider is that, although smartphone processors are becoming more advanced, the apps themselves don’t require any more processing power; if the load you’re carrying is small enough, it doesn’t matter how big your engine is.

Two new highly requested iCloud plugins just got added to ChatGPT, giving people who rely on Apple’s Mail and Calendar services a way to search emails, check appointments, and manage their schedules directly through the chatbot.

The integration is rolling out to all ChatGPT plans, including the free tier. You can access it on the web, desktop, and iOS.

Google Play is borrowing one of the Nintendo Switch’s most useful little tricks. A new Sidekick tool called Playbacks captures a short clip after something interesting has already happened, sparing players from running a screen recorder throughout an entire game.

Playbacks is part of Google Play Store v53.8 and keeps saved clips on the phone. Google first announced it earlier this month, but the new Play Store update marks its arrival for players. Anyone who has watched a perfect win vanish because the record button came too late already understands the appeal.

Samsung’s scandal over its Game Optimizing Service, or GOS, has returned with a bill attached. South Korea’s Fair Trade Commission has tentatively fined the company 20.1 billion won, or about $15.1 million, over gaming claims made for the Galaxy S21, Galaxy S22, and Tab S8.

The regulator says Samsung promoted the devices as gaming powerhouses without disclosing that GOS placed preset CPU and GPU limits on certain demanding games. Samsung disputes that conclusion, calling GOS a legitimate way to manage heat.
