Leakers claim that Huawei is including everything but the kitchen sink in the P40 and P40 Pro
Huawei typically refreshes its P series every March, but leaks about the next iteration, presumably called the P40 series, are already surfacing online. These are unverified for the time being as most leaks are, so take them some scepticism.
According to @hereYashRaj and @RODENT950, who have both proven reasonably accurate leakers in recent months, claim that the P40 Pro will feature a 6.5-inch AMOLED display. Both also state that the panel will have a native 2K resolution, while the former claims that it will have a 120 Hz refresh rate. The screen will approximately have a 98% screen-to-body ratio too, which Huawei will achieve by using a "waterfall display".
Another highlight of the P40 Pro will be its 64 MP primary rear-facing camera. The two leakers disagree over which sensor Huawei will use, with @hereYashRaj claiming it will be the Sony IMX686 that Xiaomi debuted in the Redmi K30 series. Conversely, @RODENT950 reports that the sensor will possibly be the IMX700 instead, or at least one that Sony exclusively licenses to Huawei. The P40 Pro may sport four other rear-facing sensors too, with @hereYashRaj reporting that macro, telephoto, time-of-flight and ultra-wide cameras will complement the main 64 MP sensor. Huawei will also bless the P40 Pro with two front-facing cameras, one for standard shots and another for taking group selfies.
Elsewhere, the P40 Pro will feature 50 W charging that will be capable of recharging its 5,500 mAh battery in 45 minutes. @hereYashRaj claims that its battery will incorporate graphene materials too, allowing Huawei to make it denser than conventional lithium-ion cells.
While the above may prove far from the mark, you can expect the P40 series to have exceptional camera hardware. The series will likely arrive without Google Play Services though, which will likely make it a tougher sell outside of China.
