Donkey Kong Bananza Review: The Best Switch Game in Years Is a Switch 2 Exclusive

DK is helping me punch my way through summer.

Summers are about big, fun, mind-numbing movies. Great escapes in the best of ways. I need that right now, and maybe you do too. I’m happy to say that Donkey Kong Bananza is here to whisk you off to multilevel worlds of satisfyingly smashing madness, to cheer you up and give you an excuse to punch the heck out of things. It’s a game my 12-year-old son has loved playing along with me, although I’ve had to find ways to wrestle the game back to play for myself.

I was wowed by Bananza during an early preview a few weeks ago, but after a few weeks of play at home, it’s even better. This is my favorite Switch game since… I have no idea when. Maybe since Super Mario Odyssey.

The catch is that you need the new Nintendo Switch 2 console to play it. Donkey Kong Bananza won’t work on the original Switch — or on any other gaming device. Of course, that’s the whole idea.

Nintendo needed home run games for its new Switch 2 console, and it hit a grand slam with the new Donkey Kong. I still haven’t finished the game, but I already know it’s the best reason to buy a Switch 2 yet.

Donkey Kong Bananza comes out tomorrow, July 17. It’s available for preorder now for $70 from Nintendo.com and other retailers. We’re also keeping track of Nintendo Switch 2 restocks if you’re still seeking a console.

Smashing story with co-op options

In a lot of ways, Bananza feels like Zelda and Mario met in the middle.

The story’s weird, but what Mario (or Nintendo) game isn’t? Donkey Kong’s world has been threatened by a sinister bunch of apes, after a large meteor knocks a mining company deep into the planet’s core. The adventure involves diving down into those sublevels — it’s Donkey Kong Hollow Earth, or Journey to the Center of the Kongiverse. The big difference in this game is that you can destroy just about anything, burrowing and tunneling throughout the game’s large 3D maps.

Technically, this isn’t a true collaborative co-op game, but there’s a mode where Pauline — a young girl who mysteriously fell from the sky and becomes Donkey Kong’s friend — can throw her voice, literally, at things to destroy them. A second player takes over as Pauline and aims and shoots words at enemies, and can absorb material powers from nearby rocks and objects. It’s more engaging than the hat-throwing co-op in Odyssey.

You can Game Share Bananza with a local Switch 2 or Switch 1 in co-op mode to play on two screens, or just play on one. For this review, I wasn’t allowed to Game Share to a second Switch.

The Mario mojo

Bananza is made by the Super Mario Odyssey team, and its 3D platforming feels like a Mario sequel. You can wander through large but still self-contained sublevels that remind me of the Kingdoms in Super Mario Odyssey. As you descend to new levels, the characters you meet and the level’s game mechanics shift up a bit. The levels aren’t as drastically different or quite as weirdly whimsical as the ones in Odyssey, but they feel a lot busier.

Jumping and punching are the main ways to control things, but there are plenty of other moves. There’s also a skill tree of abilities to unlock and power up, which uses points you accumulate by collecting giant, crystal bananas (just go with it). Donkey Kong can also buy new outfits, much like Mario Odyssey, but these outfits (or pieces of outfits) give extra perks, like cold resistance or faster energy recovery.

Each of the levels has goals and sub-bosses to fight, but also secret subchallenges to discover — some of them 3D, some 2D side-scrolling. There are other things to find, in every direction, on any potential hillside or surface, if you just pummel your fists and dig. The free-digging usually involves either finding more crystal bananas or various-sized fossils, which can be collected and redeemed for costumes. There’s gold to accumulate, too, which acts as general currency. But even as I rush to the next goal on any level, I’m equally tempted to just start digging around and see what’s going on somewhere else.

The Zelda zeitgeist

Here’s where Bananza really starts to feel like a lower-key Zelda game, especially when it comes to finding characters and following sub-missions. You can talk to lots of the strange characters in each sublevel, and some share important news. You’ll get directed to a particular goal, and on a 3D map, you can track your progress or warp to other spots. But as the game’s progress starts to wind up and down through sublevels, it begins to feel a lot more quest-y than any Mario game.

Zelda: Tears of the Kingdom kept coming to mind for me. That game’s vast overworld and underworld — and its various ways of finding passages between — is very much like Bananza. Also, like recent Zelda games, you can climb just about anywhere (or surf chunks of rock you rip out of the ground). The outfit perks feel Zelda-like, and so does the game’s sense of real-time, chaotic physics. Some puzzles involve understanding the environment and manipulating it, much like I did many times in Tears.

There’s also a sense of persistence in Bananza. You can create little home bases that let you rest up and change outfits. You’ll meander off and come back to locations. Mario Odyssey had some of this too, but Bananza feels more lived in.

Unlike recent Zeldas, though, this game’s challenges are relatively contained. You won’t have long lists of subquests or stories to lose track of. After spending months away from Zelda, and coming back not remembering what I was meant to do next, I appreciate Bananza’s simpler vibe.

A whole new yet familiar feel

Most importantly, Bananza just feels fresh. I get a little tired, sometimes, of diving back into new Zeldas and Marios that layer legends on top of legends. Donkey Kong’s universe is different from previous Kong games, especially the giant, wrinkled Elders who preside over subworlds like spirits, granting extra transformation powers. This is where the «Bananza» name comes in.

Accumulating enough gold triggers a chance to become a spirit animal. There’s a Bananza version of Kong that has stronger punches, an ostrich that can fly and drop egg bombs, and a zebra that can run fast over ice and water. (I haven’t unlocked any others yet.)

After a week-plus of playing, I’m still consistently surprised by what I’m encountering. But I’m also finding it familiar and comfortable, just like a big summer movie. And that’s what this is: Nintendo’s big blockbuster summer game, one of the best I can remember. Something I don’t want to end, and I’m glad to have more to explore.

I’m also surprised by other things: there’s no online mode, which I don’t mind but feels surprising after Super Mario Wonder’s clever additions. The game download size is only 8GB, shockingly small compared to Switch 2 launch games like Cyberpunk 2077, which were nearly 60GB. I was getting worried about how much storage space I’d have on the Switch 2 over time, but if more games are like Bananza, things will be OK.

My youngest son was instantly interested in Bananza, so much so that he didn’t want me playing without him. I had to, though, so I could carve enough time out to play. We’re going to backtrack and play again, and he’ll start playing, too. Will Bananza feel as replayable and infinitely fun as many of Nintendo’s best? I can’t entirely tell yet, but there’s already so much I’ve skipped over in so many levels, I don’t doubt it. There’s also a 3D art mode thrown in as a bonus where you use the Joy-Cons to sculpt and paint ape heads and bunches of bananas.

Donkey Kong makes it worth buying a Switch 2

Bananza is a great sign for where Nintendo’s heading with the Switch 2. It feels like a more evolved version of many Switch games of the past, but just like Mario Kart World, the other major Switch 2 exclusive, it takes the good ideas even further. Bananza is also an extension of Nintendo’s universe, including the Super Mario Movie, which has a Donkey Kong that looks like this one, and Super Nintendo World, which has a Donkey Kong land, too. And yes, Super Nintendo World’s Donkey Kong Power-Up bands even work like Amiibo with this game.

This is a game as vibrant and kinetic as Sony’s fantastic Astro Bot and similarly full of things to search for and do. In comparison, Super Mario Odyssey now seems surprisingly quiet and chill.

And yes, this game is worth getting a Switch 2 for — that was the idea all along. It’s nice to see that Nintendo really pulled it off, though. Combined with Mario Kart World, this is a heck of a one-two punch. I’d still love a proper 3D Mario sequel someday, but Bananza is practically that right now.

Kohler Wants to Put a Tiny Camera in Your Toilet and Analyze the Contents

The company’s new Dekoda toilet accessory is like a little bathroom detective.

Some smart litter boxes can monitor our pets’ habits and health, so having a camera in our human toilet bowls seems inevitable. That’s just what kitchen and bathroom fixture company Kohler has done for its new health and wellness brand, Kohler Health.

The $599 Dekoda clamps over the rim like a toilet bowl cleaner, pointing an optical sensor at your excretions and secretions. It then analyzes the images to detect any blood and reviews your gut health and hydration status. Depending on the plan you choose, the subscription fee is between $70 and $156 per year.

At toilet time, you sign in via a fingerprint sensor so that the device knows who’s using the facilities. (Please wash your hands before signing out or tracking your progress.) Then, check in with the app for the day’s analysis and trends over time.

Wait until you’re off the pot, though, before you start doomscrolling your health. The device has a removable, rechargeable battery and uses a USB connection.

Kohler says it secures your data via the aforementioned fingerprint scanner and end-to-end encryption, and notes that the camera uses «discreet optics,» looking only at the results, not your body parts.

«Dekoda’s sensors see down into your toilet and nowhere else,» the company says.

Kohler warns that the technology doesn’t work very well with dark toilet colors, which makes sense. I’m sure there could be an upsell model with a light on it. Maybe the company could add an olfactory sensor, since smell reveals a lot about your gut health too. It could track «session» length or buildup under the rim to alert whoever has responsibility to clean it.

Kohler must have been straining to find appropriate lifestyle photos to include with the publicity materials. Many of the images are hilarious, featuring fit-looking men and women drinking water and staring off into space contemplatively — probably thinking about gas.

Does Charging Your Phone Overnight Damage the Battery? We Asked the Experts

Modern smartphones are protected against overcharging, but heat and use habits can still degrade your battery over time.

Plugging your phone in before you head to bed might seem like second nature. That way by the time your alarms go off in the morning, your phone has a full charge and is ready to help you conquer your day. However, over time, your battery will start to degrade. So is keeping your phone plugged in overnight doing damage to the battery?

The short answer is no. Keeping your phone plugged in all the time won’t ruin your battery. Modern smartphones are built with smart charging systems that cut off or taper power once they’re full, preventing the kind of «overcharging damage» that was common in older devices. So if you’re leaving your iPhone or Android on the charger overnight, you can relax.

That said, «won’t ruin your battery» doesn’t mean it has no effect. Batteries naturally degrade with age and use, and how you charge plays a role in how fast that happens. Keeping a phone perpetually at 100% can add extra stress on the battery, especially when paired with heat, which is the real enemy of longevity.

Understanding when this matters (and when it doesn’t) can help you make small changes to extend your phone’s lifespan.

The science behind battery wear

Battery health isn’t just about how many times you charge your phone. It’s about how it manages voltage, temperature and maintenance. Lithium-ion batteries age fastest when they’re exposed to extreme levels: 0% and 100%.

Keeping them near full charge for long stretches puts additional voltage stress on the cathode and electrolyte. That’s why many devices use «trickle charging» or temporarily pause at 100%, topping up only when needed.

Still, the biggest threat isn’t overcharging — it’s heat. When your phone is plugged in and running demanding apps, it produces heat that accelerates chemical wear inside the battery. If you’re gaming, streaming or charging on a hot day, that extra warmth does far more harm than leaving the cable plugged in overnight.

Apple’s take

Apple’s battery guide describes lithium-ion batteries as «consumable components» that naturally lose capacity over time. To slow that decline, iPhones use Optimized Battery Charging, which learns your daily routine and pauses charging at about 80% until just before you typically unplug, reducing time spent at high voltage.

Apple also advises keeping devices between 0 to 35 degrees Celsius (32 to 95 degrees Fahrenheit) and removing certain cases while charging to improve heat dissipation. You can read more on Apple’s official battery support page.

What Samsung (and other Android makers) do

Samsung offers a similar feature called Battery Protect, found in One UI’s battery and device care settings. When enabled, it caps charging at 85%, which helps reduce stress during long charging sessions.

Other Android makers like Google, OnePlus and Xiaomi include comparable options — often called Adaptive Charging, Optimized Charging or Battery Care — that dynamically slow power delivery or limit charge based on your habits. These systems make it safe to leave your phone plugged in for extended periods without fear of overcharging.

When constant charging can hurt

Even with these safeguards, some conditions can accelerate battery wear. As mentioned before, the most common culprit is high temperature. Even for a short period of time, leaving your phone charging in direct sunlight, in a car or under a pillow can push temperatures into unsafe zones.

Heavy use while charging, like gaming or 4K video editing, can also cause temperature spikes that degrade the battery faster. And cheap, uncertified cables or adapters may deliver unstable current that stresses cells. If your battery is already several years old, it’s naturally more sensitive to this kind of strain.

How to charge smarter

You don’t need to overhaul your habits but a few tweaks can help your battery age gracefully.

Start by turning on your phone’s built-in optimization tools: Optimized Battery Charging on iPhones, Battery Protect on Samsung devices and Adaptive Charging on Google Pixels. These systems learn your routine and adjust charging speed so your phone isn’t sitting at 100% all night.

Keep your phone cool while charging. According to Apple, phone batteries perform best between 62 and 72 degrees Fahrenheit (16 to 22 degrees Celsius). If your phone feels hot, remove its case or move it to a better-ventilated or shaded spot. Avoid tossing it under a pillow or too close to other electronics, like your laptop, and skip wireless chargers that trap heat overnight.

Use quality chargers and cables from your phone’s manufacturer or trusted brands. Those cheap «fast-charge» kits you find online often deliver inconsistent current, which can cause long-term issues.

Finally, don’t obsess over topping off. It’s perfectly fine to plug in your phone during the day for short bursts. Lithium-ion batteries actually prefer frequent, shallow charges rather than deep, full cycles. You don’t need to keep it between 20% and 80% all the time, but just avoid extremes when possible.

The bottom line

Keeping your phone plugged in overnight or on your desk all day won’t destroy its battery. That’s a leftover myth from a different era of tech. Modern phones are smart enough to protect themselves, and features like Optimized Battery Charging or Battery Protect do most of the heavy lifting for you.

Still, no battery lasts forever. The best way to slow the inevitable is to manage heat, use quality chargers and let your phone’s software do its job. Think of it less as «babying» your battery and more as charging with intention. A few mindful habits today can keep your phone running strong for years.
