Huawei rumored to be developing graphene battery tech for the P40 Pro

The next major smartphone release from Huawei is likely to be the Huawei P40 Pro, the successor to the P30 and P30 Pro. It’s not expected to be revealed until 2020, but a tweet has listed some of the specifications and features that may be planned for the phone. While the source is not Huawei and the rumor should be treated as speculation for now, it hints at an interesting battery-related breakthrough.

The rumors says Huawei may introduce graphene technology to the P40’s battery, increasing the capacity without drastically increasing the volume, and helping to speed up the charging. The tweet says the battery will have a 5500mAh capacity, and be equipped with a 50W fast charge system to recharge it in 45 minutes.

Many companies are working on graphene battery technology, and Huawei is one of them. In 2016, it announced graphene had been used to help reduce the operational temperature of new batteries used for its base stations, thus increasing the cell’s lifespan. Higher capacities and faster charge times are also often associated with graphene batteries, but the technology is very new and we have not seen widely available, consumer-level examples of this yet.

Further Huawei P40 Pro specifications

In addition to the battery, it’s speculated the Pro model of the Huawei P40 will have a 6.5-inch OLED screen with a 120Hz refresh rate and a dual hole-punch selfie camera, plus a similar waterfall-style look taken from the Mate 30 Pro. The phone may have a five-sensor camera produced with Leica on the back. The main lens may have 64-megapixels, and be joined by a 20-megapixel ultrawide lens, a 12-megapixel telephoto lens, plus a dedicated macro lens and a time-of-flight sensor too.

What’s the likelihood of all this happening? It’s compelling and possible, but you should remain skeptical for now. Samsung dominates mobile with its own OLED screens fitted with a punch hole, and the majority of other manufacturers that adopt this notch alternative are forced to use an LCD panel instead. The 120Hz refresh rate mentioned in the rumor is also above the 90Hz refresh rate that has been made popular this year by firms including OnePlus. Asus uses a beautiful 120Hz panel on the ROG Phone 2, but otherwise, it’s a rarity.

Before this rumor list appeared, another report said Huawei may bring the launch of the P40 series forward to earlier in 2020, rather than the late March release we’ve seen for previous versions. However, with no end in sight for the ban on U.S. companies doing business with Huawei, hopes of it running Android with Google Play Services are slim. This has halted the Mate 30 Pro’s wide international release, meaning the global availability of any P40 Pro is also still in doubt.

Huawei’s P50 Pro Plus has an even more unusual camera bump than we expected
huawei p50 p50plus renders leaks pro plus

Huawei is gearing up to launch the P50-series of smartphones soon. While we've seen leaks and renders of the presumably cheaper and not-as-cool P50 and P50 Pro, the P50 Pro Plus has been a bit camera shy -- at least until now. Now, new renders from leaker HoiIndi shared on Twitter have given us a good look at the phone, especially its outlandish rear. The Huawei P50 Pro Plus may have the same oval-shaped camera enclosure we see in the smaller phones, and these renders show off the finer details obscured by earlier ones.

We can see Leica branding, as expected from Huawei, written vertically on the bump, and from what we can see it looks to be a five-camera affair, likely sporting an ultrawide and a telephoto in addition to the two extra lenses. Around the front is a very minimal design. The same very small hole-punch selfie camera as we've seen in the P50 and P50 Pro leaks makes a return, and the screen appears to have very slim bezels for an immersive experience.

It might be an older phone now, but the Huawei P20 Pro is still sure to impress. It has an eye-catching design, a long-lasting battery, and still one of the best cameras we’ve ever encountered on a smartphone. But as impressive as it is, this phone is not perfect, and we’re not just talking about the fact that it isn’t on sale in the U.S.

Common Huawei Mate 20 Pro problems, and how to fix them
Hauwei Mate 20 Pro

You’ve got your Huawei Mate 20 Pro in your hands, but there’s something you’re not sure about or an issue that just doesn’t seem right. You may not be alone, and your Mate 20 Pro may have a gremlin or two inside. Here’s our roundup of the most common problems being reported about Huawei’s otherwise very impressive phone.
Problem: Write permission to SD card not working for third-party apps
Some users posting in the XDA Developers forum have reported having an issue transferring files from their Mate 20 Pro to an external SD card. In particular, this issue arises in some cases after upgrading to EMUI 10. Huawei and Google apps remain capable of transferring files to an SD card, yet some third-party apps can't.

Based on posts in the forum, it's not entirely clear what is causing this and whether there's a single solution guaranteed to work in all cases. According to Huawei's own comments in its official forum, this is in fact a design feature implemented "to ensure smooth system performance and data security." Nonetheless, users have suggested the following potential fixes, which may work in certain cases.
