Actually battery test is kinda pointless for high end frag ship.
I mean, if the difference is small (Around 1 hours).
If the difference is big, then need to consider.

There are midrange phone with superb battery life. Even better than flag ship. Eg, Mi Max, Asus Zenfone M1 Pro. Those with 5000mAh battery.

Not quite agree with you. Haha.. I came from mid range. Once you sensitive to this 1 hour battery life, is hard for you to use flag ship. Especially nowadays midrange phone with powerful processor and camera as well. You can't image how far can a midrange go when come to battery life. 7-8 SOT is consider normal. Some user can stretch even more.

I am trying to tell myself don't be so sensitive to battery life so that I can use my M20 pro happily.

You suggest that I should go back to mid range which can easily get 10 hours of SOT? No, right?
I mean I cannot be too sensitive to battery life, coz there is midrange phone out there totally beat Mate 20 Pro to the ground in term of battery life.

That's why I said it is pointless. Else I will suffer on OCD in battery life after change to mate 20 pro. haha..

Ya, that's the reason why I am using Mate 20 pro. coz I cannot simply take battery life as a point to use this phone. Else I will start to miss the midrange battery life.

This one different la. Is because of the curve.
All OLED screen will have off color in different angle.
You try to rotate your phone so that the curve is 0 degree towards your eye.
Then you will notice the curve no green light, but the rest of the screen is green.

You buy a products A with RM 10 and products B with RM 1 from supplier.
Products A market price = RM 100
Products B Market price = RM 50

You sell Products A with Products B as free gift. And tell the whole world you give RM 50 as free gift.
But in fact, you only need to lost RM 1 to increase the sales.

Get the logic?

Those free gifts I get from my Mate 20 Pro, I sold out at half price. To get instant discount.

Too big for me. But I am using Mate 20 Pro now. scarify a little it of battery life over my RedMi Note 5 pro for superb camera, I am ok with it.

Wah... this is good!

Is normal in the sense that is LG screen design "limitations" or "issue".

Coz every mate 2 pro with LG screen has the green tint issue including me.

It is good if they allow us to exchange. What I'm afraid is they solve it by using software which is to increase your lowest brightness. Cox the green tint only saw in very dark environment plus very dim screen with grey wallpaper. The green will go way when you increase the screen brightness.

No, I think you must have installed some apps which contain ads.

Mid range no curve screen la aiyo...

I also have green, but is minimal.
To be honest, rarely notice the screen.

Those photo you guys post, really serious. And makes me wonder that is a green picture. Haha...

My M20P also LG screen.

Nope, it only happen in lowest brightness and in a completely dark room.
Once you turn your brightness lightly up (like 10%). then green tint is gone.

That is my case.

Erm.. when view from side they color is off.
I think that is what they refer to.
This happened to Pixel before, if I remember correctly.

I think LG OLED technology is not as mature like Samsung OLED. Is their design limitation.
That's why they don't think is a problem..

I read from China forum, some claim that the BOE screen don't have green tint, but the lowest brightness is bright.
I am guessing BOE is smart enough to contained the issue by increase the lowest brightness of the screen.

I bet for next firmware update, Huawei might also will limit the lowest brightness so that the green tint will go off.

I am more a technical person. I hope the information that I provided sufficient to provide you guys a better idea of what is actually happening.

I don't have the severe edge green bleeding that you guys talking about. It is weird.

My brother P20 Pro vs my Mate 20 Pro. (Mine is LG panel)
Photo took by iPhone 7 Plus.



Left is P20 Pro
Right is Mate 20 Pro.


P20 Pro top are greenish.
Mate 20 Pro overally are greenish.

But if you look closely, Mate 20 Pro is not Green. It is lack of blue color.
To prove that I am right.

I used some apps (Color Detector) to measure the image RGB,




Mate 20 Pro RGB is (50, 56, 44) (High green, low blue)
P20 Pro RGB is (63,66, 73) (High blue, green and red nearly same)

It looks like what I need to do for my Mate 20 Pro to become the color like P20 Pro is to changing the display color temperature to a "Cooler" color.

Too bad the display temperature that allow us to config in the Display settings can't drastically tune the display color temperature.

So, I was thinking, It is like software issue in stead of hardware. I might be wrong.

And photo looks more obvious than naked eye.

The spreading for me is more like because the screen is curve.

The P20 Pro top side also slightly "greenish" compare with middle.

Guys, look at this.

The Oreo Card style Recent App is back after you Remove the Huawei Launcher.

Yeah~~~

For those flagship phone...
I have to admit EMUI is the worst.

There is a lot of small animation which EMUI is unable to pick up compare with Samsung and MIUI.

Another green tint analysis compared with Galaxy Note 8

I compared my Mate 20 Pro with my friend Galaxy Note 8.

Guess what...

Mate 20 Pro have Green Tint
Galaxy Note 8 have Red Tint







So, it looks like LG have different way to handle the low brightness compared with Samsung.

Below is the photo that took using my iPad Pro. In a complete dark room.
Please note that the photo looks much more obvious than naked eye due to auto long exposure.

The different is not as much as you see in the photo. Especially the screen "evenness". LG OLED looks not as smooth/even Samsung OLED. Well, if the Mate 20 Pro cost RM 4599, I am pretty sure we can get same smooth/even OLED quality.

Hope it helps to answer you guys some doubts.


Below is one of the Mate 20 Pro green tint issue video explain I saw in Youtube last night. The good things about the video is the reviewer he tune down the exposure time of recording camera to show you what's the naked eye view.

Mate 20 is LCD screen. Should be ok.

I think what you refer is the green bleed in the curve. Is different from the overall green tint I guess?
I remember Google Pixel have this overall tint as well, it is called blue tint.
