Phone as slim as the S25 Ultra but with a 10,000 mAh battery coming next year
This unnamed phone ( translated source ) is likely a result of new strategies that are being developed to combat the limits of silicon batteries. While 7,500 mAh batteries are becoming more common, phone manufacturers want to see just how far they can push these new cells. Recently, the Honor Power debuted with a large 8,000 mAh battery, and the company has already released a new phone with a battery capacity of 8,300 mAh. From a purely numerical perspective, Apple and Samsung have fallen extremely far behind. The idea of an iPhone or Galaxy flagship with a 10,000 mAh battery, let alone an 8,000 mAh battery, is a pipe dream.
However, there is a lot more to batteries than you might initially assume, especially when it comes to silicon batteries. A 10,000 mAh phone that's slimmer than 8.5 mm sounds excellent, and it is, but it won't last nearly as long as your iPhone 16, Google Pixel 9, or Samsung Galaxy S25.

Samsung just announced the Galaxy Z Fold 7, and it keeps the same battery that the Fold 6 had, with a capacity of 4,400 mAh. In my opinion, the Fold 7's battery is pretty good. It's not mind-blowing, but it will be working at much better capacity after a couple thousand charges than its silicon rivals. This approach also complements Samsung's much longer software support cycle, while most Chinese phone manufacturers rely on people upgrading more often. Honor might be going against the grain, however, as the newly-released Magic V5 foldable phone will also get seven years of support.
If you change phones often, then silicon batteries are definitely a more enticing option. And a slim phone with a 10,000 mAh battery sounds like a dream come true. Especially if you're against Apple and Samsung's recent approach with the Galaxy S25 Edge and the iPhone 17 Air, which sacrifice battery life for aesthetics.

Oppo A6 series to bring some surprises
Oppo's A5 family launched in China in December and March with the A5 and A5 Pro, and the company is already rumored to be working on the upcoming A6 series, which will allegedly bring about some interesting changes. While it's unclear how many devices it will comprise, there will be two new, or at least differently named models: the A6 GT and A6 Max. These are both said to target the CNY 1,000 or thereabouts market - that's approximately $139 or €119 at the current exchange rates. Oppo A5 Pro for China Despite the low price, we should apparently expect to see them sporting large flat LTPS OLED screens with "1.5K" resolution, dual rear cameras with a 50 MP main, and large batteries. They will both be powered by Snapdragon 7 series chips, though possibly older ones to hit that price point. We're looking forward to hearing more about these devices soon, and we'll let you know when we do. Source (in Chinese)

Samsung wants to expand its phones' AI chops beyond Google's Gemini
Samsung's big AI push came with the launch of the Galaxy S24 series last year, and its Galaxy AI suite has expanded in features ever since, powered by Google's Gemini - for now, at least. Today, Choi Won-Joon, president and chief operating officer of Samsung's mobile division, has told Reuters that the company is very open to alternatives. But, of course, only those that can provide its users with the best experiences. Samsung is already in talks with both OpenAI and Perplexity to integrate their respective AI services into upcoming smartphones, most likely starting with the Galaxy S26 family. Samsung is nearing a deal to invest in Perplexity and integrate both its app and assistant into its phones, a previous report claimed in June. And OpenAI is also in the running, but with no investment from Samsung. Choi said: "We're talking to multiple vendors. As long as these AI agents are competitive and can provide the best user experiences, we are open to any AI agent out there". While speaking about Apple's rumored entry into the foldable smartphone space, which Samsung has dominated so far, Choi thinks this move would be beneficial for the entire industry. The company is also evaluating both the upcoming Snapdragon 8 Elite 2 and the Exynos 2600 for the Galaxy S26 range, and it sounds like a final decision hasn't been made yet.

Slim phones with 10,000 mAh batteries are possible, but may be a bad idea
If there's one shared grievance among all smartphone users, it would likely be something related to the battery. Regardless of the brand you use, chances are you'd like your phone to have a bigger, longer-lasting, and faster-charging battery. That's true for me, my friends and family, and the vast majority of people who take the time to answer our polls and participate in our discussions. Given all that, it's no surprise that whenever a smartphone with a giant battery makes the news, people get at least intrigued, if not outright excited. That's also the reason the recent rumor of a phone the size of a Galaxy S25 Ultra, but with a 10,000 mAh battery, may sound like a dream coming true. I hate being a killjoy, but if something sounds too good to be true, it usually is for a reason. I won't say that silicon batteries are a scam, but there's definitely a catch, which is why some of the biggest smartphone companies in the world avoid them. Recently, we've seen a few Chinese manufacturers adopting silicon-carbon batteries with much higher capacities than traditional cells. Among the latest examples are the Honor X70 and Oppo K13, featuring 8,300 mAh and 7,000 mAh batteries, numbers are possible thanks to the updated technology of the lithium-ion batteries. In silicon-carbon batteries, the graphite anode is infused with silicone, allowing it to store more energy in the same space. In theory, the difference can reach ten times, which makes silicon batteries have a much higher energy density. The Honor X70 has an 8,300 mAh battery | Image credit — Honor Simply put, you get much higher capacity for a battery of the same size, which allows slim phones and foldables to have better batteries. That's the reason the Honor Magic V and Oppo Find N5 have larger batteries, despite being thinner than the Galaxy S25 Ultra . However, that achievement comes with its own problems, which are the likely reason we won't be seeing more of those batteries anytime soon. You might have heard that there are limitations for flying with lithium-ion batteries. While the whole battery shouldn't exceed 100 Wh, there's also a 20 Wh limitation for each individual cell. If a battery exceeds that limit, it has to be treated as a dangerous good, and it wouldn't be easily allowed on airplanes. Unlike the US regulators, we usually measure the capacity of smartphone batteries in mAh. That can easily be converted to Wh, and @UniverseIce has recently done the math for some of the most popular smartphones. Here are their capacities in Wh and mAh: You might wonder how the OnePlus 13 manages to pack a 6,000 mAh battery and pass regulatory checks. After all, its capacity puts it above the 20 Wh limit. The answer is simple and obvious in the notes on the official OnePlus 13 specs page – it adopts a dual-cell design, so each individual cell has a capacity of 3,000 multi-cell design is also the reason you can carry your laptops and tablets on airplanes without labeling them 'dangerous goods.' But that's not the only challenge with silicon-carbon batteries. Even if the major manufacturers follow OnePlus' example and decide to go the multi-cell way, that won't solve all issues. One of the greatest challenges that pure silicon batteries face is extreme expansion. When completely charged, the structure of a fully silicon battery can swell up to 300%, which would put mechanical stress on the battery and affect its functioning. I mean, have you ever seen a swollen battery and not worried? I haven't! Manufacturers limit the expansion by using a silicon-carbon composite instead of pure silicon. Adding carbon helps the structural integrity, reduces swelling, and helps with other issues. For example, the low electrical conductivity of silicon can slow down charging and lead to the production of more heat, but carbon reduces these effects. Phones with best battery life in 2025: Independent test results Essentially, the more silicon in a battery, the bigger its capacity, but the lower the longevity. The good news is that companies are working on ways to solve those issues and improve our phones' batteries. The bad news is that it'll probably take a while before we can see the results on our smartphones.I'm all in for a battery tech breakthrough that would make my phone last forever, but that's only part of the equation. More efficient chipsets and improved energy management have already boosted battery life. The next step might simply be using current tech in smarter it's all about making a choice. On the one hand are big batteries, which may not retain much of their capacity for more than a couple of years, but will last longer during that time. On the other hand are the smaller batteries, that might need a charge more often, but will likely keep their capacity for all 7 years of software updates we get with modern choice Apple, Samsung, and Google appear to be making is a combination of safety and longevity, while some Chinese brands opt for flashy specs. I am with the giants in that regard, but I like that we finally have a different choice. Switch to Total Wireless and buy 2 months of a 5G Unlimited plan to score the phone free!
