Question Charging light never goes green - Asus ROG Phone 6 / 6 Pro

Hi. I contacted Asus about an oversight in their software. The charging light only goes green at 81% so if you set the charging limit at 80% the light will never turn green.
If you'd like this fixed please leave a comment.
Here is a link to a zentalk post if you'd like to make some noise there.

"Fixed"? Depends on how you interpret the light indicatior. ASUS gauges relative to total battery which I bet a lot of users are happy with and find logical. It btw also has the advantage that if you temporary disabled your charge limit to juice up to 100% without protection but forgot to switch back, it's a nice reminder that you may want to switch the limit back on again for better battery life.
What they could do is making both options selectable. That way both groups of users are happy.

If it turns green at all levels over 80%, then it is so by design. They are using the 'greater than' logic instead of 'greater than or equal to'.
What happens if you set the limit to 79%? Does it then turn green at 80%?
And what difference does it make if you just stop charging at 81% instead of 80%? Why bother with such insignificant detail?

Yes because I have the charging limit set to 80%. So essentially I don't get the green light at all.

I'm asking have you tried setting the limit to 79%? If so, does the green light come when battery reaches 80%?

It can only be set to 80% 90% and 100%. Also the battery would never reach 80% if the limit is 79%.
If the phone knows it has reached the charging limit it should display a green light.

Haha. That's true.
So you get green light if you set the limit to 90% or 100%, but not when you set to 80%. Correct?

Pretty sure it's an oversight. Mode 2 does what you mentioned. Only showing green at 100%.
Mode 1 displays green at 81%.
Looks very much like an oversight to me.
Being able to customize the values would be cool too

Yeah. Looking at it it looks like they just messed up.
Having to keep checking the battery % is annoying. Renders the lights useless for this purpose

It is a very minor change required at their end. Just set it to 90% and forget about the theory of charging till 80%. There is very insignificant benefits from that practice. Different OEMs seem to have different thresholds for this theory. Samsung gives an option at 85%.
I always charge my phones to 100% every single time. My phone batteries have never given me problems in 4+ years.

The idea is that when the battery degrades I'll raise the limit and get a bit extra battery. Thats that ev do

You will hardly see any benefits of sticking to a practice like this on your phone which you would most likely replace in about 4 years time.

Would have been nice on my last phone tbh
For now I'm using gsam to send out a notification

Mode 1 and Mode 2 do exactly as expected and as described.
It's just a matter of how you perceive the charging range. They use the actual 0-100% of the entire bat capacity to reference the indicator off. You would like a relative scale based on your selected max charge - which also has merits, but they haven't gone for that or built that in as an option. Adding it as an additional mode could probably do the trick. Either way, a tiny detail...

When you have one feature make another unusable it's not a tiny detail I'd say.
If mode 1 displayed green 1%lower it would be fine

[REQUEST] Infrared mode patch.

Can a dev please make a patch implementing this app/script/hack. The Inc has a red theme so I may be willing to go with a red display if it truly doubles battery time. I read something about adding an option to the developer app. Being able to turn it on and off would be ideal.
Thank you all in advance,

I would also be interested in something like this, if it can give me longer battery life.
Ehh if youre really desperate for battery life why not just do the recalibration trick? I'd rather have the battery run out quicker then have the phone look like that anyway.
The thing i don't get about this is they claim it can give your phone double your battery. Wouldn't the only thing this effect is the draw from the screen? I mean we already went from the lcd screens to the amoled screens and they are supposed to use alot less power and i haven't noticed any difference. My screen is only like 5% of my battery draw also....

this is correct. it won't make our batteries last twice as long, but it may reduce the power used by the display by about half. our display is not a battery hog to begin with. AMOLED is more power efficient than lcd 3/4's of the time. the only time AMOLED draws more power is on an all white or mostly white screen. this is why the web browser appears to kill the battery so fast.

I think that's a reporting bug with the stock Incredible ROM, because screen shots from a Nexus One show the screen being far and away the largest power draw. Flashing my Incredible to CyanogenMod also showed the screen as a large power draw (75% or higher). I didn't notice any appreciable difference in battery life either.

I had similar results using the yeti rom. Display was always in the fifties or higher.

I'd rather not use my phone at all if I had to use it with that red tint. I understand someone using this to test but why would you want to use this all the time? If you need more battery, go buy a new one. Turning this on defeats the whole purpose of having such a nice phone and screen. It's like buying a V8 and disabling 4 cylinders to save gas.

I can see how it would be useful to toggle on in certain situations (emergencies, etc). The amber tint didn't seem quite as hard to look at as the red did.

Yeah, I'm quite sure that number/percentage is a weighted average. That's why "cell standby" appears so high, I think each one of those categories could be duty cycle or total percentage of potential power drain, such as 65ma/120ma= 55%, although it's obvious that the display will be one of the major drains -- it's always "on" unless the screen is fully asleep or the phone is off--let's not forget the backlight, which is totally independent of pixel intensity/color's specific power draw.
I'd like this as well, if only because the lowest brightness is pretty bright to my eyes in complete darkness!
I am really interested in seeing this on the incredible.
I am an amateur astronomer, and the night vision mode would be really nice to have.
We may have AMOLED screens but soon there will be a ton a people with LCD screens... remember the switch because of the screen shortage?
Granted I probably wouldn't use it much... it'd be more of a novelty for me.

Battery calibration app

Could someone please develop a good app that would enable the battery to be drained as much as possible and to charge slower so we could all properly calibrate our batteries?
Do we really need this since it's a Li-ion battery? I know Ni-Mh and Ni-Cad has memory effect, but not on the Li-Ion battery.
I was just wondering the same thing today....simply because there seems to be several different methods to do it. Some say charge 8 hours, turn off, charge and hour, unplug, turn on charge 10 minutes. Then other methods say to do something different....be nice to have an app to walk you through different methods so you know step by step your doing it right
I calibrated mine last night and I'm going to get about 18 hours if not more from it....before yesterday I was getting 9.
The ONLY other different I did was make some profiles on CPU but I cant imagine it would make that much of a difference. I bet its a mix of both

That is to funny I was just saying to my wife the other day that I should make one of these programs seeing that there are none already. I hate having to manually kill my battery every night before I charge it again.
Is it needed? It depends on your school of thought, some say yes, some say no. All I know is that on the few devices I have had in the past, if I constantly plug them in to "top them off" then the battery never ends up lasting very long after a few months of doing that. So I am a believer in killing the battery before charging on devices like these.
So the bottom line is if there is a desire for this, I may try to put an app together for it, as I know myself I am interested I just didn't think many others would be.
All the battery calibration tools, are basically deleting the file... right?
Is it that hard to boot into recovery and wipe battery stats?

I think the second part has to do with hardware. The phones hardware just doesn't have trickle charge implemented and instead lets it drop back down to 90% then starts charging it again.
As for the second part, it came on our phones, even has a default widget. 4G

Um... actually that is (by most accounts) bad for Li-Ion. You want to AVOID completely draining them. All of this stuff is more art than science, but I have way more often heard that completely draining LI batteries is bad. What kills them is the number of cycles they have been through (like -25 +25, -25 +25, -50 +50 would be a full cycle).
You do however want to give them a full up down cycle once in a while (maybe every 1-3 months) for calibration.
Then again, as I said, it is more art than science, and I have heard your method as being better, but the not draining argument seems to be the vast majority.
I'll try to do a little look-see and update this or repost if I find any stronger evidence.
the thing about my phone and battery that ALWAYS baffled me was i would plug it in at night be it at 10% or 22 i would leave plugged in while slept i would wake up unplug and look at battery percentage and it would be like 95.....no other phone has even unplugged and dropped 5 percent by doing nothing????
turn your brightness to 100% and change it so that it never turns off; use wifi tether and play a 720p movie at the same time; oc your kernel to it's highest stable frequency. it'll drain pretty quickly.
I know I might get flamed for this....
Apple suggests, with their laptops, to once a month or so, run the battery completely down. Then let the battery cool down for a little bit. Then give it a full, uninterrupted, overnight charge. I forget if they said to repeat this a second time, then you're good.
This is all from memory of me reading this a couple years ago or so, so our might not be verbatim. Their laptops use lithium ion technology...
(and they used to blow up and melt down too!) Lol!

That's because the phone stops charging when it reaches 100%, and runs off of battery probably until it reaches in the low 90s, then charges again. You won't ever notice this because the light will always be green. However, you'll notice that unplugging it a few moments after it turns green, the battery will stay anywhere from 100%-98% for a while. At least on my phone it does.
Is there any way to make this program "auto run" during sleep so it can do everything it needs to do during the night charge (similar to quickpull for blackberry)

I am by no means an expert so if you find any reliable info on this and can link us to read, I would love to learn more. All I know is that it is commonly said to drain rechargeable batteries and that I have seen that topping them off very often does lead to battery life degradation.

There is no need to fully drain the battery. Its purpose in calibration is to configure the software that is correlating voltage to percentage charged. That's all. Regarding the old Apple advice, that is doing the same thing. It will not affect the hardware.
Now, what WILL affect the hardware is charging itself. Every charge/discharge cycle will reduce the total capacity of the battery. This is why the EVO will not cycle on it's own until 10% discharged. It's improving the overall battery life by that restriction.
In short, you will save money overall by getting a higher capacity battery that you don't force to charge too often. Draining your battery does nothing but give you peace of mind and it only really needs recalibrating when it's total capacity has been reduced which isn't often. 3-6 months.

Btw - what are the charging calibrations people are using? Are you seeing one working better than another?
Im a noob, so take what I say worth a grain of salt but yesterday I did the standard method where you fully charge...turn off...plug back in until led changes green and do it a few times.
I went from 9 hours to 17 hours with no other changes except a few profiles in setCPU.
I did this just last night so my results are fresh.

A few SetCPU profiles is all it takes to see a dramatic increase in battery life, especially while screen off. If you disable it I bet whatever gain you think was from 'calibrating' it disappears.

Power Saving Mode?

What's that do? It's on the display menu. Turned it off and didn't noticed a diff.
Was playing with a Nexus S at Sprint. Picked it up and it had system updates waiting...cool. Comparing everything side by side... very similiar performance to epic: screen rotation, sig strength, data speed.
Nexus display seemed a little "crisper" and for the first time in a while, I noticed the bluish tint on my display....

It dulls the white when it thinks it should. Turn it off, it only waste battery life from polling; Just like auto screen brightness, its BS unless you go in and out of dark/bright areas all the time, it polls about every 1 or 2 seconds, what a waste, just put it on 50%, I've seen the best battery results from this. The voltage used at 50% when scaled to 100% is more then when scaled from lowest brightness to 50%, in short 50% uses the least amount of power compared to lowest and highest setting, just trust me...

^^ This I find difficult to believe. The greater the brightness the more power is used, so if the lowest brightness setting remains static I doubt it uses more power than 50% setting. If anything, the opposite is true.

Ok here is what I mean, say at 0% on the slider is .9v , 50% is 1.1v, and 100% is 1.5v, 50% would be the best of both worlds, you can stillsee the screen and you save more compared to 0% - 50%, then 50% - 100%, its not that hard to understand...
And Chris, the power saving mode adjust white level (not brightness) when veiwing a bright page, or scene or pic...

[Q] Battery self charging!?

Hey, has anyone noticed their battery meter saying a low percentage and then seeing it increase after not touching the phone for a while? ive noticed my phone will say 2% for example and ill let it sit for a while and when i check it again its all the way up to 10%. I have calibrated the battery but it doesn't affect it and it still happens?
lol yea my battey is solar powered.. lol jkjk.. but naw its because when your screen is on it adjusts tye percentage based off how your using it.. if its asleep for a while tye battery percentage will increase because its not being used make sense?

Nope, it actually doesn't make sense.
You're gas gauge in your car doesn't go up when your car isn't being used. Percentages shouldn't increase without charging no matter what.
FWIW, I've experienced this a few times. My battery has increased as much as 5% without being charged and that's in one string. For example, my battery may go down to 50%, then over the next 20 minutes go to 55%, then an hour later 42% and rise up to 45% and so on. Not sharp spikes either, steady gradual increases.

No, it does not work like that.
Battery app re-calculates the remaining battery based on the battery power currently being used (mV) and history. That's why we are doing the calibration to correctly measure the current battery status and range of it.
In most case, battery power (mV), it goes down from the top and it usually up & down within a small range but for overall, it goes down.
But sometimes, the current mV is goes up and it's caused by
1. Battery usage forecast was wrong or
2. Battery is recovering its power again - for example, after CPU intensive task, the voltage could goes up
3. the remaining percentage goes up if the battery usage is slower than the expectation (it's not going up because it's not being used. Even the screen is off, the battery is still being used). In this case battery app recalculate the percentage based on the current mV and trend that how fast battery mV is decreasing. If mV is increasing, then battery app will show like it's being charged...
There are couple of more things that we also consider in here but I think this is enough information to know.
Update: Let me add a couple of more.
From OP's screenshot, it shows that there's big drop in battery percentage. Usually, big drop happens (battery power is decreasing so fast), it's really hard to calculate the exact remaining percentage because battery shows some irregular pattern after that kind of fast drop. So, some point of time, battery app recalculate the percentage based on current voltage. That's why it's showing going up.
One more case is, the pattern change. After big drop and/or voltage is about the same (stay almost same), then battery app also adjust the remaining battery level indicator.
Simple example) Just like Human. I just finished eating and fully charged. After a meal, I worked so hard and almost exhausted. No power left. But after a little break, I could recover my power a little more.
This example is not exactly same but it would be more easier to understand.
I have noticed this. Could it be that after the battery runs out the phone puts itself in a low consumption mode, thus the battery cools down, increasing the efficiency of delivering power, thus increasing the apparent voltage available? This would be similar to putting the battery in the fridge to get a litte bit of extra juice...

Its just the phone reading the voltage wrong, the calibration is outta wack.

Makes complete sense. There is no accurate way to judge the potential energy stored within a battery. Changes in temperature are one of many things that effect the chemical availability of energy.
Little shifts in measured overall capacity and current charge change all the time on every device you own. Most of them do not update to reflect this, some dont update in the wrongest way. My ASUS gaming laptop doesnt report new full charge capacities to windows and now more than ever with the battery being half shot i can hit 150% but it always did this from new sometimes would show it had stopped charging at 98% when it reached full capacity or 101%.
I can explain the software aspects of the problem. But you will need an electrical engineer, chemical analyst to help you go over the batteries end of it. I of course am not familiar with Android in particular but Portable PC's Sony's PSP etc seen it everywhere.
Its due to a flaw in Samsung phones where it does not correctly read the battery. Sometimes a phone reboot will show as much as a 70% (from my experience) in battery but then my battery will start to "charge" itself as the phone reads the voltage better. I've seen this happen on our phones and the captivate

You're gas gauge in your car doesn't go up when your car isn't being used. Percentages shouldn't increase without charging no matter what.

you have no idea how mechanical measuring works, do you? here is an example of how gas is measured; a floating ball attached to an arm changes the voltage of the signal depending on the amount of fuel in the tank. Higher the ball, higher the voltage, and thus higher the gas gauge.
Consequently, you will notice fuel gauges reading higher going uphill and lower when going down, because gas doesnt just sit in one place. The gauge is usually calibrated for when the car is standing still.
Now that you have an idea how mechanical measurement works, can you apply this to battery chemistry? NO, because they are completely different!
Battery life is measured using a formula, not a mechanical device. It is, in essence, a best guess. Some formulas are better than others, but they are all still estimates. And you will notice fluctuations.

Hey, has anyone noticed their battery meter saying a low percentage and then seeing it increase after not touching the phone for a while? ive noticed my phone will say 2% for example and ill let it sit for a while and when i check it again its all the way up to 10%. I have calibrated the battery but it doesn't affect it and it still happens?

i had the same thing happened to me, and i have the pic somewhere.. where the battery just dropped from like 80% to 30% in less then 5 min.. i was using it, and had the screen off, and had it on again.. and it went down like crazy.. and afterwards.. it started to go up, as if i was charging the phone..
some one said that, its a bug by samsung, where if you charge your phone not quiet to 100% and use the phone, this can happen..
concerning what some other guy said about turning the phone off and on, can boost batery power.. that was hilarious sad..
likkkkkke thisssss?
first one is recent.. second one is from one of the initial ics leaks..

Or yes as you can see it clearly (or in your case, not so clearly) going up at points it's not being changed

However very much expected. You have created a circumstance where accuracy was guaranteed to be off. Making sure that multiple corrections were a reality.
I would hope that in a 2 day period you had 3 to 4 hours to sleep where this phone could have reached 100% twice and only been on the charger about 4 times. Obviously a couple very busy days for you. I could guess any number of occupations that might have done this to you

That looks almost as if to suggest the sampling did not occur at all while the phone was sleeping.

Now that you've got that out of your system, let me explain it a little more simply so you understand.
It was an analogy. I never said that battery percentage was calculated the same way as fuel capacity. But it's an analogy to help you relate.
Batter percentage is a measure of volume of power left in the battery. It should never fluctuate UP without being charged, unless something is wrong with the battery/phone. 55% is 55%, no matter what temperature, usage time, current usage is. If the battery is 1800 mah, then 50% battery level means there's 900 mah left. It's not a calculation of anything else. Just like if your fuel tank hold 16gal, and the needle is at 1/2 (stationary of course, not parked/driving up or downhill as you needlessly pointed out), you have 8 gal left. There's no mathematical calculation needed there.
Just for reference, I own no other electronic device that magically increases in battery percentage. My laptop goes down unless it's being charged. It's a quirk/flaw with the system in the phone. Plain and simple.
BTW, no apology needed. I'm just happy to educate you!
Didn't you know? Our device's covering is actually made of solar panels

FWIW, I've experienced this a few times. My battery has increased as much as 5% without being charged and that's in one string. For example, my battery may go down to 50%, then over the next 20 minutes go to 55%, then an hour later 42% and rise up to 45% and so on. Not sharp spikes either, steady gradual increases.

My gas guage goes up when i park uphill.

Does anybody else find the battery low LED annoying?

Is there any way to disable it via a script or something?
I think its annoying that it blinks when battery is at below 15%
At least it would be better if it started doing it at 5% at 15% there is still a lot of battery left.
Cheers
It's barely visible to begin with.

Really?
The LED is already perfectly made not to disturb you?
Why does it annoy you? it tells you that the battery is low so you know that without having to turn on the screen.. And why would it do it at 5%.. its perfectly fine at 15 because it is low battery .. and 15% is like 1 hour top ..
So i dont see the problem here really..

I can't agree more. It's almost useless because its so barely visible. How hard would it have been to give us a blackberry style LED.

Seems just right to me, though I prefer the GNexus notification led.

I, for one, wholeheartedly agree! I would love to be able to delay the flashing until it's at at 5% instead. Or maybe at least decrease the frequency of the flashing...
sine 15% is still a lot battery left, it is kinda annoying if the battery is low in the evening and blinks every 2secs.

Well its not only annoying it does however little consume battery by blinking ALL the time after 15%, and I don't know about you but I average about 3.30 hours of screen time every day.
One of the things I have done is disabled the backlight for the three capacitive buttons, apart from other settings of course.
And the only LED I have enabled is the notifications/messages.
I would prefer it blinks after 5% because I still have alot of battery left at 15% apart from the fact that I find it as I said before annoying.

To me its very visible but if to you its barely visible then ask yourself what's the point of it blinking at all and consuming the little battery left?
Wouldn't you rather have it disabled in fact since you barely see it?
Must be a simple way to mod this with a script...
Cheers
15% is when you should really be plugging in to charge to prolong battery life. Don't wait to 5% unless you really have to.

Can you elaborate more on why it would prolong the battery life at 15%? With 15% I can still travel for 2,3 hours on the road and make calls and surf if needed.
I never charge it until its off or at 1%

Just from what I read about our batteries they perform better and longer in the 20%-80% range. I run my phone out sometimes though. I think this is HTC's reason at 15% though.
