Notification LED only shines green when charging - Huawei P9 Questions & Answers

I always wondered if the notification LED should show me the charging status by beeing orange when it is charging but the battery is still low.
My P9 is only showing me a green light, not making a difference how much is left to charge.
I am asking myself, because i recently saw a Honor 6x showing the charging status by different colors.
PS: I have Android 7.0 running

Normaly it should be orange until the phone is charged 90% then the LED should turn green.
Did you try a factory reset or update to the newest Firmware.
Do you have a custom rom like BluWei or Lineage OS ?

it s all vanilla without any modifications. and yes, i factory resetted it several times :-/
CAN somone with a P9 confirm, that his LED can turn orange during the charging process? Maybe it s just the P9?

From 0% to 9% it's red. From 10% to 89% it's yellow, not green or orange and from 90% to 100% it's green.

ok, never got it below 20% because of i want to get easy with the battery (and not charging it above 90%)..but i will try noticing next time i charge :good:
but here again, the 6x it´s a deep yellow, clearly distinguishable from a green.

so yes, 90% upwards the light green turns into a dark one. As i assume that the color change also works under 10% i have to admit that maybe the coding of this colors is absolute i mean from 11% to 89% the led is green (a light green), so it doesn´t help me at all. apes must have programmed it by choosing which banana to eat.

i have the same problem
with my honor 9 lite non of other honor 9 lite have this problem

LEDs status

The only LED I ever really noticed on my Hima was the blue one telling me BT was on or off. I know the device has a green, yellow and red LED on the opposite side that can either burn or flash, but don't ask me why. Neither do I know if the flashing rate of the blue LED might tell me something.
Last week when my battery was just about 99.9% drained and my Hima started to behave strange, I noticed that on external power the red LED burned constantly. And when I notice something like that, it's probably because I've never seen it before.
http://michael-channon.spaces.live...._c=BlogPart&partqs=cat=Hermes+Charging+Issues helped me out.
But I would love to know the exact meaning of all LED colours and blinking rates.
all the Leds's Rate are in the Book that comes with it
Thanks, but as I told before I bought 2 Hima's with broken screens years ago, under those conditions it's very rare to get anything but the dead device itself.
The service manual only tells me that a fast flashing yellow LED means battery is too warm (>35C) or too cold (<0C) to charge.
hmmz..u r rite..its unpredictable..any way i'll see what i can find
What I can see, it's blinking green on normal operation, lighting yellow on charging, blinking red on missed calls and lighting red on too low voltage...
Mine never blinks green. Lighting green tells me charging reached 100%.
Could blinking green mean GPRS or IR on?
Anyone ever seen blinking yellow?
I hope curiosity only kills cats ;-)
I guessed the lighting red :-(
Mine blinking green when it is in normal operation.
Yellow on charging
Red when there is misscall or message because I set to give LED sign
> Green for normal - with carrier signal operation and Fully charged while still plugged into wallsocket
> Yellow for Charging
> Red - missed calls/poor elec current while being charged/very low battery
@Maggy, there is a tweak on how to permanently disable blinking lite even during normal operation. could it be possible that ur units have are tweaked like such?

Not that I can remember, but I'm tweaking all the time. Aren't we all?
;-)
how come on my XDA my colors are
Yellow=Normal Operation
ORANGE=Charging
Red=Low batt
May be your led is expired Yellow and Orange is slighly different, you lose green color I think every body mentioned yellow in here is little bit mix with orange color
Or some of us are more colour blind than others

[Q] Notification light constantly yellow

Hey!
As it says in the title the notification light stays on continuously shining yellow. Have tried to do a factory reset but it still shines. Does anyone have any idea what could be wrong?
Using the stock rom and the phone is rooted if that matters. Read somewhere that it could be the battery thats low but the phone is fully charged.
Sincerely,

[Q] Charged 100% and Orange N LED?

Hi all,
I am running CM7 and I noticed that my Nook was charged to 100% but the LED on the charging cable was still showing orange. Have you guys seen that? If I charge it overnight, the orange LED will go away eventually and I'll see the green LED in the morning. Is that a bug in the code?
Thanks.
You can try to wype battery stat cache trough recovery.
Do it when it'svfully charged (green led)
Just Reboot
That usually works for me.
yeah I think there is a small area where the battery says 100 but it's really not full. I've noticed this too and watched it as it charged...five or so minutes after I noticed, it turned green.

Power Indicator Doesn't Change Colors

I updated my NC to run CM7 off the SD card and whenever I go to charge it the Indicator built into the USB cable never changes to Green when the battery is completely charged. Is always stays the yellow color. Anyone else notice this?
ya same with mine it never changes colour...
For me, sometimes it turns green, other times it doesn't. Seems to charge up OK either way though.
Odd I have CM7 flashed to the emmc and it always turns green when fully charged. Is everyone who's having a problem running off SD?

The green indicator is not tied to the battery percent gauge on the display. It takes a few hours after the 100% reading before the green light goes on...

that doesn't sound too right. it should turn on at 100% immediately right?
and i thought i'm the only one with this problem.

Nope... the green light is tied to a voltage comparator. When the threshold exceeds the predetermined voltage, the light turns green.
The battery gauge is tied to a ADC (analog to digital converter). That's how it determines the percentage power left.
The two are independent. The question was previously addressed:

[Q] Charging the M7 when it's off

I've let it charge for maybe like 3-4 hours, assuming its fully charged, and when I turn it on it's almost there (maybe around 95%). So I'm just wondering when you charge the phone while it's off does the LED light flash green when it's fully charged.
Also can someone tell me what it means when you see the red, blinking light while the phone is off and charging.
Mine glows green constantly when fully charged. When it flashes red while it is off or on, it's from overheating in all instances I've seen and experienced.
