Just for information: I measured a difference of ±25 mA in current consumption between 120Hz and 60Hz refresh rates.
So, in practice, if you have a SOT of 8h at 60Hz, it will reduce it by ±4% = ±20 min with 120Hz.
Enjoy

Im starting this thread because i honestly cannot find an explanation of mA's anywhere else. I have abnormally high mA usage (according to my batter monitor widget) around 300-400 when the screen is on. What exactly does the mA mean so i can try and kill the app draining my battery?

mA is milli Amps, it's how much power your phone is using at that time. WiFi, 3G, your screen, your screens brightness, your CPU speed, bluetooth, etc all add to that.
That isn't high usage if your screen is on, that would be about normal.
mA is not a unit of power; a watt is the proper unit of power. However, mA's or amps, are used to compute power.
In the water hole analogy,
voltage (measured in volts) is the water pressure
amperage (measured in amps) is the size of the water outlet
watts (volts x amps) is the resultant volume of water exiting per unit time.
In the context of your phone, depending on load, more or less current is consumed or drawn.
Google ohms law for more info.
Edit, an example, a 100 watt light bulb consumes .833 amps of current at a voltage of 120V. 7.5 of these light bulbs consume approximately an equivalent amount of power as produced by 1 hp (ie, 1hp = 746 watts).
To maximize your battery, please add a setcpu profile for charging.
Set the frequency as low as it can when charging.
Reason:
The battery will stop charging when it gets to a certain positive voltage input.
If we set the frequency high, the battery will stop earlier as the consume it bigger than low frequency.
Perhaps you can further explain this. Is the voltage measured at the battery? If so, how does the battery drain affect that measurement? Does changing the CPU voltages affect this? Is this an effort to increase battery capacity? Or increase charge rate?

The voltage is by the formula, Input - output.
If it is positive, the battery keep charging.
However, not all positive voltage keeps charging as at some very low voltage the battery will stop charging.
So, keep the voltage as high as it can to longest the charging cycle, and you phone can get highest capacity.
The core temperature of my CPU reaches ~55C and my battery temperature reaches about ~44C while charging.
While downloading apps from playstore temperature of my CPU reaches ~45C
A point to consider is that this was done at an ambient temperature of ~28-30 C.
Are these temperatures acceptable or shall I visit Asus store or ask for exchange..
What is your CPU temperature?
Mine jumps from 45 to 65 when in idle and that seems kinda high to me.Measured with antutu benchmark tool
Hi guys. I've searched every post about heating problems but I have a question about S20/S20+.
When I use it for basic stuff like Facebook and whatsapp, my phone battery temperature gets 35c after a few minutes. If I open intensive cpu apps, it raises to 39, 40. I am using Ampere app to monitor.
Is that normal? Do I have to worry about it? I live in Brazil and ambient temperature inside my house is 27c.
Can you share your battery temp here after using the device for a while?
35c to 45c is well within the thermal limits of your device. Naturally if you live in a tropical area the ambient temperature is going to be higher and thus would have a negative impact on the device's temperature.

Just realized that if device hits 40c Celsius, it automatically turns off 120hz. Just happened with me. If I use camera for more than 15 minutes, it hits 40

That's normal. I'd be more worried if the device didn't do that automatically. Prolonged camera usage (esp 4k) causes a lot of devices to heat up regardless of the brand.
