Lollipop: Heart monitor coming on whenever. A source of battery drain? - Galaxy Note 4 Q&A, Help & Troubleshooting

Since my Lollipop upgrade, I have noticed I can turn the heart monitor LED (low power laser?) on by placing finger over it. When some sensor is covered, the light goes on. Screen on or off. S Health loaded or not. Doesn't matter.
This is a problem because it'll turn on while in my pocket or laying with its back on the table. My phone was very warm and showed significant battery drain when I checked after I left a theater the other night. I believe the light was probably on the whole time.
Anyone else notice this behavior? My Note 4 is Sprint Note 4 with no root.

That's why you are having the problem I think.Try uninstalling it and see if that works...

ARGH! I just can't take the lack of a notification LED!

It's finally driven me to the point that I'm just going to sell the Nexus for a profit and get a G2. I can't take picking up my phone every single time I want to check if I have a message. I've never had a smartphone without this feature, and it's just a nightmare.

I do miss having an LED indicator too... but I wonder if they took it out due to battery life reasons. Is there an app that can help give better indications in case for missed calls or texts that can do a reminder without an LED indicator... maybe even use the LED light on the back of the camera is better than nothing
i would say just wait until someone makes it so it uses the LEDs under the softkeys as notification lights

Use NoLED, works great for me. I like it more than the trackball notifications on my N1 now, they look awesome on the screen.

I don't want to power-on the screen for a notification that may be left un-noticed for an hour.
I didn't really like the idea of NoLED either but I just decided to try it for the hell of it. I use the blink mode and set the time out to 1 hour so if it's idle for an hour the notifications will stop. I've checked the battery drain and it seems to be quite small with blink mode at least (since I'm only having it display the notifications for 1 second every 30 seconds). So really, 2 seconds of screen time every minute, which is about 120 seconds every hour, or about 2 minutes of screen time where it's mostly black and a few lit pixels, and then after that 1 hour it stops.

I tried noled but must confess I never spent any time setting it up so the battery drain I noticed may have been avoidable.
Just to pick up on the above... I'd want the notifications instantly obvious so that a quick glance at my phone would notify me of any messages. Using the above method I'd only see a notification for some of the time and not all.
Lighting up the bottom buttons would be a much better option for me but in the meantime I might try noled again.

Other than the fact that they're not colored, seems a bit better IMO, more noticeable. Also, battery drain really is minimal with NoLed...

The three pixels on the screen drawing power aren't going to impact your battery life heavily.

to be honest id be more paranoid about burn in , cuz really if i get a text when im sleeping and it goes unnoticed for 8 hours then what
With NoLED you can set notification timeouts, I have mine set to 30 minutes because I always have my phone near me and 30 minutes is plenty. I also have it set to use the Proximity sensor so that if the phone is in my pocket it's not displaying any notification, only when you remove the phone from your pocket and the proximity sensor detects that it's clear will it display the notification instantly. You can also set a "sleep" time for notifications, so I have mine turn off at 2am and turn back on at 6am.
If there is any increased battery drain I haven't noticed it, but then again I don't leave notifications on flashing for hours either.

The notifications move around the screen to prevent any pixel burn-in. You can set them to timeout after a certain amount of time also.
Have you guys even bothered trying out NoLED? Haha
Good to know but on top of that don't the notifications move around the screen?
Edit: ikon beat me to it.

NO!, i fear change!
Have the phone make a sound/vibrate. No need to pick it up.
or download noLED. Problem solved.
I've made a couple posts in the Poor Battery Life on NS? thread( such as http://forum.xda-developers.com/showpost.php?p=10143276&postcount=159) detailing my experience with the Nexus S's battery.
I use noLED as my notification system with large icons rather than the default little dots and no time out method. The only other special thing I've done to it is turn on the proximity sensor so noLED doesn't run while it's in my pocket. My boss likes to do a lot of paperwork in the super late evening/early morning and sends me emails accordingly(this is why I don't leave the sound/vibrate on, lol). noLED's impact on battery life is extremely negligible. I would put it on par with the power with the power consumption of an actual LED notification light due to the way SAMOLED and blacks work.
And, if you're worried about burn in, like someone said, the icons shift around the screen in order to avoid that.

that proximity sensor idea while its in your pocket, genius
Just tried noled again and am noticing a few force close errors.
What settings are best for this app and when a notification is received, what are you using to wake tje phone again as the power button causes issues as explained in the splash screen after install?
I'm also seeing all the bottom buttons light up as well as the notification on the screen, is this normal and if so is this not consuming battery unnecesarily?
Seems a tad buggy to me this app on the Nexus S. Would appreciate exact settings / configuration from anyone that has it running satisfactorily.

Battery won't charge past 88%.

I am sure there are other ways, but if you are running CWM you can try booting into recovery and clearing the battery cache.
wiping cwm bat stats doesnt do anything. Still cant charge beyond 88%. Should I exchange for another one?

If I could I would - have not had any problems of this nature myself, you are (I think) the first or second person here on XDA to report this - since you just purchased it perhaps a exchange would be a easy fix

Are you charging with the tablet turned on? If so, I've had a similar situation where it wouldn't charge past 92% while plugged in. I just ran it down to almost no battery, shut the tablet off, charged it up while I slept, and all was well again,
My left side is creaking anyway. So i will exchange tomorrow.
how come there is not a 'never' setting for when screen turns off? I cant keep it on to drain battery.

There may be other ways to do it, but look for extended controls in the market. It has an option for 'screen always on'
Hope that helps

You can use GPS Test to keep the screen on. Found in market.
I use screebl. I love it because I set it to turn off my screen in 5 seconds when the tablet is flat on it's back and to never turn off then I have it on my lap.
That way I can download or do anything and it won't turn off on me and I don't have to manually lock it if I set a long timeout for the screen and I just place it on my desk and do something else.

Thank you so much for telling me about this app.
I just got a new iconia. I actually had a choice to exchange for either another iconia and a transformer. After weighing the options, I went for the iconia. The ports just can't be beat. I've been incorporating the gtab in to my work. I am now going to incorporate the iconia into my work. The full usb and hdmi just can't be beat.
About the new iconia that I got, wow. Very solidly built. No creaks at all. Testing out the battery now. I'm going to let it run out of battery from 36% that came with it. Then I'm going to charge it all the way up. Hopefully, this one will go to 100%.
Playing around with it, I can already tell this runs smoother than the one I traded in. I guess the other one just had hardware problems.
Anyway, I am happy that I was able to find one within 10 minute driving distance. I called around this morning and almost every place is out of iconias. Then I called this place 10 minutes away and they had 1 more in stock.
Anyway, I'm happy with the end result.

[Q] Slow charging with orb?

I got the orb recently and my plan was to use my phone as a bedside alarm clock with it. However, when I have the phone on "desk clock" mode while on the charger, the battery slowly drains overnight by around 1-2% every half hour instead of going up. When the screen is off, it seems to charge fine. Is the orb just really that slow at charging? It kind of defeats the purpose if it can't keep a steady charge with the screen on as I like be able to just glance at the time while in bed instead of having to turn on the screen first.
well the orb wont charge as fast as wall charger
but if it doesnt provide enough mA to charge while screen on i guess there is something wrong. however i dont have the orb, so cant help you any further.
It should still charge with the screen on. Mine will gain 1-2% every 10mins with the deskclock night clock on. Are you using a case?

No case at all. I am using the power adapter that came with it too, because i read using a different one caused problems too. I am however using visceralpsyche's gamma color settings from franco's thread which require you to have your brightness at 50%, but I should still be able to get a positive charge I would think.

i think you definitely still should. I know that if you place the phone on it centered near the bottom half (if you do it vertically, the phone will be about 1/2 - 3/4" from the table or whatever surface the orb is on), thats the optimal part of the phone to have touching it. If it's still not working, I'm guessing something isn't quite right with it.

I've tried a few positions all with the same results. I did notice though that with the first 20 minutes of charging, it will go up like 3-4% like it should, but afterwards it just goes on a slow and steady decline. I guess I'll contact Google about it, and I already had to sell my DT-910 because of the problems with that charger :/

Unrooted 6P on Nougat Hot in Pocket, Cool on Desk (Project Fi)

Hi, I've had my Nexus 6P since June now and I've been noticing some issues with battery life and Android N. The weird thing is, the battery is only having troubles when the phone is in my pocket. If I leave my phone on my desk the battery drains very slowly, but while in my pocket the phone gets hot and the battery drains much quicker (e.g. a short 10 minute run to chipotle for lunch left me with 5% lower battery. My phone didn't leave my pocket the entire time).
I'm using Project Fi for service and am in Manhattan, so service isn't an issue. I use the phone with backlight settings at 50% and I don't use the screen more than 30 minutes a day on average. I have location services disabled, I'm on the most recent Android N preview, I use WiFi at work and at home. I have a Pebble Time smartwatch that is connected via Bluetooth to my phone all hours of the day. My phone is Unrooted and has no custom bootloader. I don't have any apps that contribute significantly to my battery drain.
I suspect that my battery issues are from the new and 'improved' Doze feature on Android N.
I don't have a battery breakdown handy (cause I stupidly plugged it in before screenshotting) but the top stat on my battery drain is Android System, with CPU total over 1.5 hours in a given day and Keep awake over 45 minutes at least.
If anyone has experienced similar behavior or might have a clue as to why my battery is dying and how to fix it, please let me know!
Thanks!
- Eric
I turned off the 'ambient display' option in Settings/Display almost immediately upon getting the phone (which I've had for 3 days now!) I found that it would wake the screen and turn off a bunch of times if I was just carrying the phone and not actually interacting with it. I can see that being a big battery drain just for the screen time.
Good luck!
I don't have a solution, but my Nexus 6P has a similar symptom: It gets hot when it's in my pocket at work.
Based on the wifi wakelocks I've seen in Wakelock Detector, I suspect it's trying too hard to stay connected to the wireless network. We have a few access points at work, and it's possible my phone is switching back and forth between the two closest access points. It's also possible that the wifi signal isn't strong enough, so the phone boosts power to the wifi radio.
I'm on Project Fi, and I know the T-Mobile and Sprint signals are both weak at work. I don't know how much energy the phone wastes trying to keep itself registered on the mobile network, but I imagine that could also be related. Even though Project Fi will successfully use wifi to send and receive messages and phone calls, I'm pretty sure it still keeps trying to get a better connection to the mobile network (like every other phone).
It's difficult to judge whether the phone actually does something to cause a higher temperature while it's in my pocket, or if it just dissipates heat better on my desk. My pants are definitely too tight, so I'm sure that doesn't help.

Hey, thanks for the tip about ambient display. I turned it off and I'll let you know how it goes
This is pretty simple. Phones rely on airflow to remain cool because they have no active cooling. A phone on a desk has airflow. A phone in a pocket doesn't. No airflow means hotter phone. A hot battery drains much faster than a cool battery. That's all it comes down to.

Totally not what's going on. When in my pocket, the processor gets really hot, the rest of the phone warms up from my leg heat, but there is a hot-to-the-touch feeling to the top of the screen near the CPU which indicates higher clock speeds on the CPU while supposedly 'idle' in my pocket.

Hey, thanks for the reply. The "Android System" app is currently listed as using 19% of my battery followed by android OS then Chrome.
Android System has a CPU Total of 1 Hr, 30 Minutes, 34 minutes of keep awake and 800 mAh computer power use.
My screen has been on for 13 minutes and is computed as using 42 mAh.
This is all only 6 hours after taking my phone off the charger.
Thanks.

There's a lot of processes covered under Android System. I would start with location services by switching them to off for at least a day.

Essential battery 78% life and 360 camera

Hi to all. I have the essential with the battery to 78% life and even if it's full when I connect the 360 camera it shuts down the phone, is there a workaround to be able to use the 360 until the battery is 1%?

If there is, I'd be interested, too... Seems to be a known issue (I can't recall the exact battery level when my phone shuts down, but definitely above 60%).
Just tried mine at 50% and it shut down my phone when I clicked to take the photo. If I am not mistaking this started happening after 10 was released? Anyone still on Pie that can test it out?

This was definitely happening to me on Pie as well. Unable to find a solution, I just kept that in mind and only used 360 camera with a full charge.
