8849 8849 Tank 3 Pro 18GB RAM+512GB ROM 100 Lumens Review

The 8849 Tank 3 Pro is a $900 brick with a great battery and a terrible everything else. Buy a Samsung or Google phone instead and carry a power bank.

The 8849 Tank 3 Pro is a phone that screams 'more is more' and forgets to ask 'but is it good?' It's a Frankenstein's monster of a device, packing a ludicrous 23,800mAh battery, a 200MP camera, and even a built-in camping light. The one thing to know is this: it's a spec sheet hero built for a very specific, off-grid power user, and it makes a ton of compromises to get there. For everyone else, it's a confusing, bulky brick with a terrible user experience.

The performance score is decent at the 85th percentile, which is surprising given the generic 'Octa-Core' processor. It's not slow, but our database shows it gets absolutely smoked by similarly priced phones from Samsung and Google in real-world tests. That 18GB of RAM is pure overkill for an Android experience that feels clunky. The real shocker is the battery score. You'd think a 23,800mAh unit would be untouchable, but it lands in the 80th percentile. That means despite the massive capacity, its efficiency and software are so poor that it doesn't last as long as you'd expect. It's like having a 100-gallon gas tank in a car that gets 5 miles per gallon.

At $900, this is a terrible value. You're paying flagship money for a phone with mid-tier performance, awful software, and the build quality of a power bank. The only way this is 'worth it' is if your number one, non-negotiable priority is going two weeks between charges in the wilderness and you don't care about anything else.

For the same $900, you could get a Samsung Galaxy S25 FE or a Google Pixel 10. Both will destroy the 8849 in camera quality, software smoothness, screen tech, and overall polish. They'll feel like phones from this decade. The OnePlus 15 will offer similar performance for less money and in a sane form factor. Even the Motorola Moto G at a fraction of the price will provide a better daily experience. The 8849 only wins if you're comparing battery capacity in a vacuum.

If you're looking for a good smartphone, this isn't it. Go get a Samsung Galaxy S25 FE or a Google Pixel 10 instead. Only consider this if your job description literally includes 'must have a phone that can power a small appliance for several days.'

We cannot recommend the 8849 Tank 3 Pro to almost anyone. It's a niche product masquerading as a mainstream phone, and it fails at the basics. The terrible user reviews and complete lack of brand reputation are huge red flags. Unless you are a search-and-rescue professional who needs a phone that can also double as a boat anchor and a week-long power source, steer clear. For 99.9% of people, spending $900 on this is a mistake.
