Hey guys,
I thought the big advantage of the super amoled screen was that black is simply black because no pixel is lighting. But using the phone lying in the bed when its totally dark in the room reveals that the whole screen is not actually black at all. When using Noled, for example, the battery drain is pretty heavy since the whole display has a very low background brightness the whole time. Can anyone tell me the reason for that, please?

Likely to be an idle voltage causing a slight glow.
I don't think they can turn the pixels individually off, just dim them massively

Well technically you can turn them off. The problem is each pixel is controlled by a transistor and so the level to which you can turn each pixel off depends on that. It could very well be that the transistors aren't turning off 100% and some current is leaking through. It depends on the technology used and a lot of other factors. Nothing is perfect.
So, it seems we've hit the barrier
Nexus S runs stable @ 1300 Mhz (1.3 Ghz)
unfortunately prolong use of this speed raised the CPU/Battery temperature to over 60c +
that's a bit too high for comfort
the number might be small
but actual usage performance is blasting fast
a full system restore (330+ apps) using TitaniumBackup took roughly 10 minutes @ 1300 Mhz
the same full system restore at stock 1000 Mhz it took twice as long for TitaniumBackup to complete the restore
so, now the real challenge is to find some one that can provide us some water cooling kits to install into our phones, so that we can clock the crap out of it without it overheating to death

Now that I would like to see! but it would make the phone uncomfortably bulky I fear nano-technology water cooling? Anything's possible right
Edit: those are nice times though! Considering it's not even double the 1ghz, but it chops times in half... I might give some overclocking a shot now!
Honestly im surprised we havent seen any time of cooling built into say the phones back cover as a heat sink.
Maybe in the future. but as it gets smaller the power draw gets smaller and the heat generated drops.
so who knows. its just exponential

I think power is one thing but with the poor battery life our phones have, chewing battery amps as heat is a waste generally. Energy efficiency is what they are trying to achieve, not a pocket warmer Not that i'm against overclocking though.
I recently compared my 4 month old Galaxy S-AMOLED display with a recently bought one.. There is visible difference between the maximum brightness in both screens. The newer one looks brighter with better colors when compared to my older Galaxy S. Both are GT-i9000 international version, and I used similar images to compare the screens..
Does the Super AMOLED display deteriorate with time? Also please tell me if this will covered under warranty..
It does deteriorate quite quickly. Especially the blue pixels. Not keeping it on high brightness levels helps the screen deteriorate less quick. And I'm not sure but I had read somewhere that when it comes to "burn in" if the effected area is greater than 8 pixels then you can replace it under guarantee.

Yes every lcd screen would die one day but Super AMOLED dies with burn in faster, but still would give you 3-5yrs of life.
On daily basis keep the brightness to low or lowest when you need to brighten up put finger on notification bar & slide it to right (bright) slide it to left (dark).
Hope this helps you to get more life from your lcd.
thanx a lot guys.. will go for warranty and let yawl know how it goes..
I was able to get crazy good benchmarks with the phone over the AC vent. So we obviously have a physical thermal issue. I have replaced the battery 3 times twice on my wife's mi mix. So I am wondering if anyone has tried to do anything.
I had planned to use slim copper shims with some premium thermal paste but never got around to it. The thermal pad/rubber on the sd821 looks like crap.
I don't get any perfomance improvement using copper shim, also complicated to install it correctly. At some point i got ghosting image on the lcd. Because it's little bit to thick.
Different height between cpu and pmic.
I'm planning to change it with some premium thermal pads. I'm sure it will be enough, because we don't talk about a 100W processor.
What kind of temps are you getting?

Thank you for sharing! So we can skip the copper shim. What about a copper back replacement? Like make an AutoCAD of the back plate and have it CnC'd online?
I know it sound like I'm putting too much effort but I love to tinker with things.

Using miui nougat version + psychedelic kernel 0.7
Downclocked maximum cpu and gpu core.
Around 72-80c, while playing games like pubg.
I removed thermal control files also.
When normal use like browsing,chat,youtube.
It's just around 38-45c, phone is cooling down faster in my experience.
I'm living in a tropical country, my room temperature is ussually more than 30c.
This phone is a giant oven. If i install MIUI Stock just can B used to griddle Girl's Hair. So, a good 1 is adding thermal paste to the CPU CHIP directly, a good one. When i change the Battery i'll do it.

So, after some back and forth with screen protectors for this note 9, bouncing between film and tempered glass. I have much more enjoyed the film, because of the touch accuracy without adjusting any settings. Unfortunately, I much more prefer tempered glass and the peace of mind of an extra layer. Knowing that there's no full adhesive for privacy screens, my question before putting another glass on here.
Does increase the TOUCH sensitivity affect/ruin touch after a while? I ask because in parallel, having brighteness maxed out creates burns, so I wondered about the touch being increased.

No, it won't degrade touch after an extended period of time. It will decrease battery as the digitizer(wacomizer?) is using more power to penetrate the screen protector when the setting is turned on.

Thank you so much for that return. I have been on the fence about it and want to use the mess out of this phone, but still want it to last at least for the next 2 years. Thanks a million.

I've had the same glass screen protector for the last 3 or 4 months and it's been as normal as it was before putting it on.

I already 8-10 hrs of SOT. So, if I remove the screen protector and disable that touch sensitivity thing I'll get more?

Let me clarify what I stated cause I just realized it can mislead folks into thinking the amount of power consumption will be noticeable.
I don't personally think it'll be noticeable. Its possible to produce numbers of course, but to see an increase to battery life by turning off the setting might be placebo. The Wacom digitizer being used by the Note series is very power conservative. Though the extra juice would be used only when the screen is on, I really don't think it'll be that drastic of a power draw when having that setting on.
I used it without tempered glass and with.
I switched to Touch Sensivity, i turned it on and have the SAME (Exactly SAME) Standby and Screen On Times, like with normal touch Sensivity.
In my opinion : It does not consume more power.

It has to consume more power. Whether it is noticable depends on how much power it draws. If it didn't consume more power, there would be no need to include such a setting, because the sensitivity would just be cranked up all of the time.

That is totaly true ! I do think the same.
But it just does not consume more power .
Try it out plz.
Maybe iam wrong, but ive tested it, because ive tested for reviews tempered glass screen protectors.

It probably consumes 5 or 10 extra minutes of SOT that you don't even see it.
I use plastic film, I don't have the touch sensitivity enabled and no issues.

Correct, it's probably even less than that amount.

You won't/shouldn't have any issues cause there's not much more layer that the electro charge would have to go through to sense the touch(capacitive). I chuckle a little at the .9mm glass screen protectors. It's like the adhesive doesn't count at all when they post the specifications of the protector.
Technically speaking, the only folks that should have to even enable the extra sensitivity are the ones that use the protectors with the dot matrix patterns(adhesive on sides only).

The ones with the adhesive on sides is all I can find for privacy screens. Are there any others you'd recommend otherwise?

I am not using one. I recommend checking the accessories section to see what others have used and their opinion on them.
if you are in the UI Pie
You can go to seting--> Display --> Touch sensitivity!
