Affordability Meets Excellence: How Qualcomm’s Technology Could Transform Lower-Cost Phones

I review a lot of phones that cost $300 or less. And I’m always surprised by how many of these cheap phones have high-end features that used to be exclusive to expensive smartphones, like a high refresh rate display. Despite those advances, one thing I’ve come to expect on any phone under $300 is a mediocre camera.

For instance, I snagged a number of beautiful photos in Central Park on a bright sunny day with the $250 Moto G 5G. But when I took the phone to a Motorola Razr Plus launch event inside a darker venue, the images looked so bad that I had to switch to my personal iPhone 12 Pro Max in order to grab decent shots of the entertainment, Cirque du Soleil and Kim Petras.

While device makers like Motorola, Samsung and OnePlus design the hardware and software for affordable phones, it’s Qualcomm who is largely behind the processor design. And the San Diego-based company might have a solution to improve those so-so cameras on cheap phones.

A phone’s processor can help improve the photos you take by reducing image noise and expanding the dynamic range. Qualcomm, widely known for its Snapdragon 8 processors in the Samsung Galaxy S23 line and OnePlus 11, creates several series of chips for the affordable phone market. For instance the $300 OnePlus Nord N30 5G runs on Qualcomm’s midrange Snapdragon 695, part of the company’s 6 series. The aforementioned Moto G 5G runs on the Snapdragon 480 Plus, part of the more value-focused 4 series.

Part of the challenge of designing lower-end chips is that they might end up in phones coming out next year or even years after. The Snapdragon 480 Plus for instance was first revealed in 2021. So Qualcomm’s designers must plan for a slower rollout of features along a much longer timeframe as components like high display refresh rates, better connectivity and improved cameras trickle down to cheap phones. 

Qualcomm’s newest 4 series chip, the Snapdragon 4 Gen 2 chip, was first announced in June and prioritizes improving photos. The new processor supports low-light photo processing that uses artificial intelligence to make images look better. While there isn’t a US phone with the new chip that’s out yet, diving into what the new processor supports might offer clues about what we can expect from upcoming affordable phones here. 

As such, I visited Qualcomm’s San Diego headquarters in July to learn more about how the company develops chips for affordable phones and what that means for future sub-$300 phones.

Improving photography, with a little bit of AI

After price, cameras are often the biggest deciding factor for people choosing a phone. Qualcomm’s senior director of product management for the Snapdragon 4 Gen 2, Deepu John, told CNET that improving image quality is a big focus with the new processor.

“If you’re sitting in a bar taking pictures of beer or some exotic food item that you ordered, you want to be able to boast about that on Instagram,” said John.

The Snapdragon 4 Gen 2 uses artificial intelligence to assist with photo processing and improve images taken in low light. AI and computational photography are already common on more expensive phones. For instance, Google designed its own Tensor chip to handle photo processing on its Pixel phones. John notes that building AI into the chip’s camera support was a priority for Qualcomm, because people notice photo quality the most.

“So there’s dedicated AI processing that we have put on the camera on the essential functions that not only make the image quality better, but can also help the peripherals that are used be cheaper,” John said.

To assess the photography improvements, Qualcomm’s teams use emulation tests before producing a silicon chip, and then later in development use a reference phone that functions much like a standard Android phone.

Matt Lopatka, Qualcomm’s director of product management for the Snapdragon 4 Gen 2 said that Qualcomm’s partners, like Samsung and Motorola, also do a lot of work to finetune the processor, since the sensors ultimately need to be integrated with the camera hardware.

“Our partners do an incredible amount of work as well. Meaning it’s not like you can just [put in a camera like] we plug a webcam into a phone. It’s not quite like that, you have these very specific sensors. And then you have to tune the sensors to the lens to the ISP. It’s an incredibly complex system,” Lopatka said.

Faster 5G and refresh rates

Cameras aren’t the only area where cheap phones lag behind. It wasn’t until 2023 that the first sub-$200 phones with 5G were released. 5G support requires pricey modems to work. And it’s much easier for a phone with a higher price tag to absorb that cost. Qualcomm had to factor in the cost when designing the Snapdragon 4 Gen 2.

“One of the things we really focused on was manufacturer cost, because again, we’re trying to get 5G down. So that sounds weird, but 5G is almost a premium feature still,” Lopatka said. 

Qualcomm focused on optimizing its new chip for cheaper phones without sacrificing performance, which required choosing specific types of memory and components. Lopatka and John said that these are often decisions that still meet the people’s needs, but lower the overall cost of the processor.

Improvements like support for high refresh rate displays are easier to integrate because the screens themselves are getting cheaper.

“If the pricing on those displays are coming down aggressively, then that technology will get adopted faster than typical,” John said.

While the Snapdragon 4 Gen 2 does support 120Hz refresh rates, currently it tops out at 1080p resolution. The current crop of phones that cost $200 or less tend to hit 90Hz refresh rates at 720p resolution, but perhaps next year’s phones that use the chip will start hitting that higher mark.

“Even if right now, a lot of those entry tier phones are going to have 60Hz, we know very soon they are going to have 90Hz. We know they’re going to have 120Hz,” Lopatka said. “It’s kind of our job not to necessarily build it for everything that is in 2023, but also in 2024 and 2025.” 

Competition in the lower-end

Qualcomm’s Snapdragon 4 Gen 2 faces stiff competition from Mediatek for inclusion in affordable phones. The $200 Samsung Galaxy A14 5G series has a MediaTek Dimensity 700 chip. According to Counterpoint Research, the A14 5G was the top-selling Android phone in the US for the month of July, and placed fifth overall behind four iPhone models. Samsung, Motorola and OnePlus did not comment for this story.

While Apple does not currently sell an iPhone under $400, Google’s Pixel 6A running on its in-house Tensor chip starts at $349 while occasionally dipping to $299 on sale.

When asked about these potential rivals to the Snapdragon 4, Lopatka and John said that while Qualcomm does monitor rival companies, the market would ultimately decide the better product.

“It may come across as simple as [an] X-megapixel camera or dual ISP or something, but to sustain that is tough. And that’s what we constantly are driving, leading on the technology and that’s where we really stand out,” John said.

Regardless of competition, seeing processors like Qualcomm’s Snapdragon 4 Gen 2 gives hope that better photography could become a more universal feature on your next phone, whether you spend $200 or $1,200. But until we have a cheaper phone that handles night photography with ease, I’m still going to be cautious about relying on one while I’m out at a dark concert.
