The same goes for moderate to somewhat heavy use, after which there's often enough charge left over so you don't have to connect the phone to the charger overnight. Even if you're gaming and watching videos all day long (with the coronavirus pandemic forcing people to spend as much time at home as possible, that's something many folks will probably do), the A31 will easily survive for at least 12-14 hours before it asks for a charge.

The Galaxy A31 has a number of attractive features in its spec sheet: A 6.4-inch Super AMOLED display, an in-display fingerprint sensor, 128GB of storage as standard in many countries, four rear cameras, and a 5,000 mAh battery. What's not so attractive is the processor powering the phone. The A31, along with the Galaxy A41, uses the MediaTek Helio P65 chipset, which isn't great for gaming, as I've already given away in the review's title.It helps that despite the 5,000 mAh battery inside, the Galaxy A31 isn't very heavy. At 185 grams, it certainly pushes the boundaries of what can be considered a light phone, but the weight feels just right and will not be an inconvenience for anybody. The L-shaped rear camera setup is predictably the same as we've seen on the Galaxy A51 and other recent Galaxy phones. There's no text telling you the resolution of the main camera next to the camera sensors, something we've seen on Samsung's M series phones, and that makes for an understated and classy overall look. Sensors: Fingerprint sensor (under display, optical), accelerometer, gyro, compass, proximity sensor, ambient light sensor I had no issues when making calls on the A31. I could hear the person on the other side clearly and so could they, though that's only true in quiet places, like inside the house. Since the speaker isn't loud enough, you might want to use earphones when you're making calls outdoors. Network performance is excellent, for those wondering, with both of my SIM cards having zero issues getting a strong signal.

The Galaxy A31 comes with the same optical in-display fingerprint sensor as the Galaxy A51. While I still prefer the old physical fingerprint readers, I also like this one a lot. It's much, much faster and more accurate than the in-display fingerprint tech Samsung was using on its mid-range phones last year. Frankly, it's even better than the more advanced ultrasonic fingerprint tech on Samsung's flagship phones, at least when you consider the difference in price between these A series phones and the company's top-of-the-line offerings. The Galaxy A31 supports 15W fast charging (with a 15W charger provided in the box), but thanks to the size of the battery, it can take almost two hours to go from 0 to 100. So, if you're a heavy user, it would be a good idea to charge the phone overnight instead of doing so after you wake up.B1 (2100) , B2 (1900) , B3 (1800) , B4 (1700/2100 AWS 1) , B5 (850) , B7 (2600) , B8 (900) , B12 (700) , B13 (700) , B17 (700) , B20 (800) , B28b (700) , B28a (700) , B66 (1700/2100) Samsung Galaxy A31 uses a Super AMOLED display with a screen size of 6.4 inches, 98.9 cm2 (~84.9% screen-to-body ratio). In terms of resolution, it has 1080 x 2400 pixels resolution with 20:9 of aspect ratio (~411 ppi density). How many cameras does the Samsung A31 have?

The absence of a dedicated Night mode is particularly felt when you use the ultra-wide camera, which can't take photos as bright as the main camera in low-light conditions because of its considerably narrower aperture. Ultra-wide pictures taken outdoors during the day are serviceable just as long as you don't try to zoom in, because the 8-megapixel resolution isn't enough to resolve any meaningful detail. This is, however, a limitation on all of Samsung's mid-range phones with ultra-wide cameras. The Frame Booster allows you to obtain the greatest graphics and more details from your favorite games by giving them smooth, lifelike animation. The Galaxy A31 also has Dolby Atmos, which provides a 3D surround-sound experience when playing games or watching videos. How long does Samsung A31 battery last?For smooth and effective performance, the Samsung Galaxy A31 is equipped with an Octa-Core 2GHz processor which is an advanced octa-core processor, up to 8GB RAM, and up to 128 GB of internal storage, with external storage extendable up to 512GB via a dedicated micro SD card. With Music Share, you can stay connected to a Bluetooth speaker and let other devices play music on it by connecting to your phone instead of that Bluetooth speaker. The Galaxy A31 also comes with Samsung's Edge Screen and Edge Lightning features, which we don't often see on non-flagship Galaxy smartphones. Plenty of standard One UI 2.0 and Android 10 features are included as well, such as Link to Windows, Game Launcher, Dual Messenger, Secure Folder, Digital Wellbeing with Focus mode, themes support, One-handed mode, Samsung Pass, and Always On Display.

Battery : Actual battery life varies by network environment, features and apps used, frequency of calls and messages, number of times charged, and many other factors. The Samsung Galaxy A31 has fantastic capabilities that change it from a smartphone to a powerful multimedia device. It's a terrific phone for gaming since it has a built-in Artificial Intelligence-based Game Booster that optimizes your settings to offer you the finest mobile gaming experience imaginable. Aside from that, the Samsung A31 is powered by a MediaTek Helio P65 chipset, which allows for seamless multitasking and keeps the device cool even when running various programs for lengthy periods of time. The phone comes with Android 10 preloaded and Samsung's One UI 2.1 software layer. Is Samsung A31 battery life good? User Available Memory: User memory is less than the total memory due to storage of the operating system and software used to operate the device features. Actual user memory will vary depending on the operator and may change after software upgrades are performedQuad Main Camera: 648 MP, f/2.0, 26mm (wide), 1/2.0", 0.8µm, PDAF, 8 MP, f/2.2, 123˚, (ultrawide), 1/4.0", 1.12µm, 5 MP, f/2.4, (macro), 5 MP, f/2.4, (depth) At night and in low-light situations, the Galaxy A31 falters hard. With sufficient artificial lighting, photos have low noise but also a soft look. In very low-light scenes, noise goes up considerably, and detail is pretty much completely lost. To make things worse, there's no dedicated Night mode here to help you get better results in tough lighting conditions. The Galaxy A30 also didn't have one, but this is 2020 and one would expect a Night mode on all but the cheapest of phones. Network : The bandwidths supported by the device may vary depending on the region or service provider.
