The Galaxy A80 has a 6.7-inch SuperAMOLED display and it's a true Infinity one - there are no notches or cutouts. The 1080x2400px resolution in a 20:9 aspect makes for a 393ppi density.
We measured a maximum brightness of 405nits when controlling it manually with a healthy boost to 607nits when the Auto takes charge under bright lighting. Those are fairly standard numbers for the better OLED displays, and virtually identical to the results we got out of the A70.
The minimum brightness of 1.9nits is also close to the A70's result and perfectly adequate for night-time viewing.

The default color mode out of the box is Vivid, with an average deltaE of 4.4 and a maximum of 9.7 when examining color swatches against DCI-P3 targets - not too impressive. Whites and grays are reasonably accurate, however, with deltaE values around 3. You do get the option to tweak the colors with sliders but we didn't get truer P3 rendition.
Then there's the Neutral mode, which is tuned for the sRGB color space and renders it with spectacular overall accuracy (average deltaE of 1.4) with the sole exception of 100% green (deltaE of 5).
The Galaxy A80 is powered by a 3,700mAh battery - not small in absolute terms, but kinda smallish for the screen size and smaller than the power pack of the A70 (4,500mAh).
We're not too pleased with the longevity numbers we got out of the Galaxy A80, particularly in the web browsing test - just 9 hours on our web script is a low result which we hadn't seen in a while on a Galaxy. For comparison, the A70 can last 50% longer to 13:24h, while the Zenfone 6 manages a whopping 15:42h. Even the unremarkable 10:10h of the OnePlus 7 Pro is better.
The A80 does look a bit better in the video looping test, where it lasts a good 14:39h. Even here, however it's bested by all of the above - the A70 can do 3 hours more, the Zenfone 6 is good for 16 hours, while the OnePlus 7 Pro manages 16:17h in 60Hz mode (14:33h in 90Hz which makes little sense for video playback).
We're not ones to talk on the phone all that much, but the Galaxy A80 is good for a whole day and then another hour of just that over 3G. The other phones we mentioned can do 10-12 hours more, if that's your thing.
In the end, the Galaxy A80 posted an overall Endurance rating of 80h. It's not bad, strictly speaking, but it's not great either.
Our battery tests were automated thanks to SmartViser, using its viSerDevice app. The endurance rating above denotes how long a single battery charge will last you if you use the Samsung Galaxy A80 for an hour each of telephony, web browsing, and video playback daily. We've established this usage pattern so that our battery results are comparable across devices in the most common day-to-day tasks. The battery testing procedure is described in detail in case you're interested in the nitty-gritty. You can check out our complete battery test table, where you can see how all of the smartphones we've tested will compare under your own typical use.
The Galaxy A80 supports USB Power Delivery at up to 25W. We didn't get the full retail package, so we couldn't test with the bundled charger. Extrapolating from the A70's 42% at the 30minute mark, we speculate the A80 will be able to get to around 50% in as much time thanks to its smaller capacity. We'll be sure to update this section once we get a hold of a proper charger.
The Galaxy A80 has a single loudspeaker on its bottom and with no conventional earpiece stereo sound is out of the question anyway. It's putting out reasonable decibels, ranking in the Very Good category as our ratings go.
We have no complaints about the quality either - there are no issues at high volume and there's a decent amount of bass.

The Samsung Galaxy A80 does not come with a USB-C to 3.5mm adapter in the retail package, which meant there was no way for us to perform our audio quality test. We tried using a couple of passive adapters we had lying around, but the phone didn't work with either of them, suggesting that it might need an active one to work.
Performing a test with an active adapter wouldn't make sense though, as each of those has a different DAC and any results we obtain won't be representative for the actual output of the phone.
