Overheating with LED cycling colors

Heya,
Last night I was playing Angry Birds in bed while plugged in a Kidigi dock. All is well. Now let me define some preconditions first.
The phone does get hot while:
1. Charging
2. Screen is on for a long time
3. Heavy CPU load
4. That goddamn hot weather isn't helping either
Right?
Put above conditions together. Temperature is 48.3C. I never thought I'd need to use a cooling fan on a phone, honestly. I did that to an overheating AMD desktop some time ago...
The thing is I knew there was something going on not by feeling the hot phone (remember the dock part?) but by seeing the LED strangely cycling through all three colors. Anyway I shutdown everything running, turned off the screen and kept my fingers crossed. The flashing stopped almost immediately as it dropped one degree in an instant. Took it 15 minutes to cool down to the normal 38C.
I looked around and didn't find a definitive answer for this one, even on HTC's site where they supposedly list notification color meanings. Therefore I now define a new one, let's call it "I'm just about to blow up now, k10xbye".
Has anyone else had such a drastic overheating case with this type of notification?

Nope. My phone hit 52 degrees. Nothing happened to it. Just turned the screen off and it cooled down

What was the third color? Mine only flashes orange for when its dying, solid for when its charging. Flashes green for notification, solid green when its fully charged.

Charging is orange.

I monitor my battery temperature by dialing *#*#4636#*#* which takes you into a section called testing, and then selecting battery information. This displays temperature along with other info. At one time, it actually said overheating. it has not happened again but if it does, I will seek a replacement unit. There is no way that any of this, your sceneraio or mine, is normal.

It's not normal. Heavier games with 3D don't do that. Max temp achieved was 42.

My EVO4G used to do that when I had it in the tank bag on my motorcycle listening to Pandora. The plastic cover would cause it to heat up and the led would cycle and it would stop charging and shut down.
There is a reason to this. The battery is mainly lithium. Lithium is highly reactive (read lots of very hot flames and sparks and excitement that you probably don't want going off near your girlfriend or dog or sensitive government documents). They use the same type batteries in RC aircraft, only lots bigger, and youtube will show some pretty spectacular lithium battery explosions, if you care to search them.
Imagine that going off in your pocket.
Ouch, a little....

Heh shutting down is reasonable, heating up till shutdown during normal use is not. And yes I watched those videos on YouTube when I got my wrist charger.

I m also suffering... But only gets hotter when u use the phone while charging, or use the phone for almost 20 mins continuously...

Here you go. 20 minutes Angry Birds, no charging, 43 degrees. Decided to quit. Anyway I've had enough for today plus not so pleasant on the hands.

Screen killing battery?

Ok first I know what alot of you will say.. of course the screen kills the battery...
So here's what is going on. I got my gf a s4g (tmous) last week. After dealing with 7 random reboots in 2 days. I decided to root/s-off/install custom Tom. Now over the last 5 days I've installed the neon rom based on the European 2.3.4 leak. And supra based on the tmous 2.3.3 I've had the same problem with both of them. The battery is dead in 4-6 hours. When I go to about battery it says the screen is to blame (80-97%). I also noticed the other night that appearantly the screen isn't sleeping all the way sometimes. As we had went to the movies and the up time showed 3 hrs uptime with 2 he's screen on. She left it in her purse in my truck while at the movies. What's going on with this thing? Should I run the ruu and return it? Thanks for your thoughts and replys.

QHD
With that QHD display it has to render more pixels.

You should get 3.5 to 5 hours of screen on time, so if the screen isn't sleeping it should and will die in 5-6 hours. Return it. The screen should not use battery while it isn't on.

I think its pretty standard for the screen use up at least 80% of the battery, unless you never use it

Mine is lasting over 2 days using mostly phone MMS and email and a few app fun.
-Screen 35%
-Voice Calls 33%

That's kinda what I'm saying my g2x is screen on usually round 50% of the time. Yet in battery stats the screen usually only uses around 20% of battery.. anyway I restored to stock s-off t-mob010 and its better then it was but I still think I'm going to return it..

[Q] screen taking 78% of memory

Does anyone have any idea why my screen is always listed at 72% on the usage acreen? From what I have seen others are at around 40-50%.
This happens even when I have brightness lowered to 20% (and following several power cycles) so I am perplexed. Any ideas would be appreciated.
Thanks. (Edit: 72%, not 78.)

What is your screen in time?
Sent from my HTC One X using XDA Premium HD app

Thanks for the quick reply. This happens from the moment I am done charging, even after the phone has been powered down. Right now I am at around 7hrs on from dead, maybe 2hrs screen time.
Funny thing is there seems to be no variance (whether I put brightness up to 100 or down to 10), which leads me to think the reading may be inaccurate.
My soft key lights do stay on all the time, unless I am in the full sun or put the phone up to a bright light, but apparently that is normal.
Sent from my HTC One X using XDA

Just an update in case anyone else had the same issue: after about 24 hours at low brightness without a reboot, the phone finally seems to he reporting the correct brightness on the usage chart.
It's strange and I don't know what caused it to finally act normal. Just glad I don't have to consider an exchange.

Just to be clear... You meant battery, not memory. Right?

Yes, right! Battery, not memory, usage. Thanks.

Cocktailbar service and battery

I have a SM-N915K with OEM flip case. Battery life is incredibly low due to "Cocktailbar service" service eating 30-70% of the battery. The service listens to sensors and rotates the content of the edge screen probably. Anyone has the same problem? The problem can be related to the flip case use.

Cocktailbar Note Edge
I have the same issue... I figured it had something to do with the edge display but didn't tie it to the case... I'm going G to replace the back with the original battery door and see if that make difference. I'll post results tomorrow.

I use the flip case when I'm out but when I'm at home I use the regular back. The cocktailbarservice seems to be succking the life out of my battery. Went to bed at 95% and woke up at 68% while the phone sat idle. It is now 9:42 am and I have used the phone very little. I am at 37%. I love this phone but at this rate I can't even use it so I might have to return it if I can't find a fix. I'm lucky and have access to power supply most the time but this is ridiculous.

I did stop using the case for the weekend and the battery life on my phone has almost trippled! I took it off charge around 8 pm last night. Played with it intermittently until 2:30 am. Got up this morning around 9 am and still had 88% battery. Have been using it almost nonstop between calls, Internet and texts and am just now at 20%. 18.5 hours off the charger and only 6.5 of those were sleep time. If I can have this kind of battery on most days I will be happy. I am not running powersave during any of that time either. And since taking off the case, cocktailbarservice is not draining the battery. Unfortunately I have to have it in a case when in my purse, and I have two of them so I will be using the case most business days. Does anyone think it will mess up my battery to have it drain so much when using the case and then slow down drainage when I take the case off? I don't want to ruin my battery.

it was the Case
Yeah I had the same results. It definitely was the case for me too.... I have to wait till the come out with a holster or something cause I hate walking around with a naked phone.... Especially one that's $1k.....

Turning off the 'Style clock on edge screen' or limiting its duration (Edge screen > Information stream > 15 seconds) has helped my battery life. I don't think the issue is the flip case as much as it is the graphics that play on the edge screen every time the flip case is closed.

I can confirm that this does the trick. I disabled the style clock, I am 6 hours in with everything on and 1 hour screen time, battery is at 79%. Thanks for the help.

Had the same problem too and i notice it happen at night while i am asleep it could be the night clock and flip cover combination
that cause this drain. Also when i check the battery setting it shows com.android.keyguardcom.sec.android sviewcover taking up 33% ??? Its a flip case not a sview case. Can someone please advice thanks

I bought a black one here (US) at the T-Mobile store but I bought a white one for the same $38 with free shipping off of EBay. It came from Korea but it is an OEM case. This is a different seller but you could check out this link. http://www.ebay.com/itm/381075447098?redirect=mobile

guys I have question
On your OEM flip cover, when you enable the style clock does it show the right time when the phone time settings is set at AM/PM mode?
On my style clock the minutes hand shows correctly but the hour hand shows "0". I have tired all the style clock themes and all show this but when i change my phone's time settings to 24 hour clock it displays correctly...!!
Any help with this will be highly appricated

I never had this problem once I fix the cover and set the app it automatically set the right time...

Strange why is it happening for me?
I have installed the case reboot the phone as well and for some reason the style clock hour hand shows "0" while the minutes hand is correct...
Is there some defect in my case maybe?? i dont think so since all other elements like screen auto off and the incoming call coming on the edge is all well ...

Do you mean on the edge panel? If it is 6:15 it will show 06:15. Does yours show 00:15? If so I would say the phone has a defect or maybe needs to be factory reset. Sorry if I am not understanding you correctly. Mine works as it should.

Instead of showing 06:15 it shows 0:15... Maybe I should do a factory reset.

If that doesn't work you could try to exchange the phone. That seems to be a phone issue not related to the case.

Always on display

What is everyone thinking about the always on display? Will you be using it knowing that it costs 15% battery per day? Tbh, that sounds really high to me to light up such a small amount of the screen but I guess I don't know really

Where did you read that it's going to use as much as 15% battery per day? That sounds quite ridiculous given the fact that LG stated that their Always on Display implementation drains 0.8% per hour. Which is around 19% per day (24h - day and night), but the G5 uses IPS panel. There's no way if an LCD is using 19% per day an OLED screens showing primarily black to be draining 15% a day...

What you need to factor in before you start saying how high battery usage is...... How many times per day do you check your phone for notifications etc??? If you are constantly checking for texts / Facebook updates or whatever then AOS is for you. Whilst it may use X amount extra per day of battery if uses LESS power than powering on the whole screen and taking the device out of idle to check if you have any missed calls etc. If you are one of these people you are better off using AOS.

Samsung said 1%/hour. Also, LG made some adjustments to be amoled-like: “To minimise power consumption,” said LG, “we redesigned the display driver IC memory and power management function so that the display’s backlight only illuminates one small part of the overall display. Thanks to this technology, the Always-on Display requires only 0.8 percent of the battery’s full capacity per hour to operate. With consumers turning on their smartphones up to 150 times a day mostly to just check the time, the G5’s Always-on Display will make a notable difference in the life of the battery over the course of the day.”

You also have to keep in mind that when it is face down or the screen is covered the screen is off until you turn it over or take it out of your pocket or purse.

Samsung said the feature will use 1% PER DAY, not per hour. http://www.androidcentral.com/galaxy-s7-and-s7-edge-have-always-display

Everywhere else I saw said 1% per hour which makes a lot more sense.
What's weird is it seems we cannot set it to turn off at night for example

LG said their always on display uses 0.8% per hour and it's an LCD, so how does it make sense that an AMOLED display would use more power? LG only lights up a third of the display for it to save power compared to a regular LCD, but that should still use a lot more power than lighting up just the pixels necessary. Frankly, I trust Android Central on this more than any other site. They got behind the scenes time with Samsung at MWC and they are typically very reliable. The sites I see reporting 1% per hour (phonearena, Android Authority, etc.) are sites that I find very unreliable as I spot mistakes in their articles and videos all the time. Just one site probably got it wrong and then every other site copied them on the wrong info.

Here's another source that says 1% per day, so it's not just Android Central. And I know I heard it from a third source too before Android Central even wrote about it, but I can't find that now.

Edit:
Here's another source: http://www.uswitch.com/mobiles/features/samsung-galaxy-s7-always-on-display-faq/
Anyways, I guess we will know for sure when a lot of people start getting the phone. I will test it and will definitely turn it off if I find that it is using 16-20% of the battery in a day, but I really doubt it will use that much.

i think its going to be closer to the 1% per day because if you look at the s5's untra batter saver mode they have proven by reducing what the display has to show and reducing the processor power they can make the phone last a hell of a lot longer on the same charge

LG has an IPS display, Samsung has SAMOLED.
Samsung said that it should save battery because you only check the notofocations on the screen and didn't need to turn it on.
I'm not scarried from battery but from burning the display.

Worried about screen burn-in? Samsung has thought of this, too. Though the information displayed looks to often be a static image, the software is actually regularly shifting the pixels ever-so-slightly so that the same ones aren't used over and over again. This eliminates worry about those pixels "burning in" the lock screen image, and it's one you won't even notice happening. The phone also won't display the information when it detects it's in a pocket or a bag, and if you just don't like the feature you can always turn it off completely
That is a quote from the android central

does anyone know what triggers the always on display to be dim some times and bright the next? i've been trying to find a cause and i dont see any. it will be dim one minute and just become bright for no reason it seems. this is with a black background and unplugged from the charger. i would like for it to stay dim to use even less battery.

Turned it off 2nd day. Uses too much battery. I only turn it on for when connecting to charger. It's definitely near 1% per hour. I Just have the lock screen wallpaper completely black so it doesn't drain batt just to see time.
Plus always on display is pointless when it doest tell me anything more than time.

Mine does the same, i'm guessing it's designed that way to keep any sort of "burn in" or similar from happening after long term.

Maybe it's pointless to you, but I use it a lot just for the time. If your's is using close to 1% per hour, I suggest you get your phone replaced.

the always on display is definitely eating up around 1% battery an hour on my phone. this is with most of the bloatware disabled. i can look at my battery every hour and it will be down 1% some times 2%. i tested this with turning always display off for a couple hours and not turning my screen on and after 3 hours i lost 1% battery. i'm thinking it has something to do with the always on display becoming too bright at times and i dont know how to get it to stay dim.

Always on seems to turn off in pocket but not in the night. Is possible turt it in the dark and in the night automatically?
