What's eating your battery?

Here are my results for today (so far)...
Battery percentage remaining - 41%
13h 33m 9s since unplugged
voice calls- 1h 11m 27s. - 62%
display - 1h 13m 35s. - 22%
cell standby - 13h 33m 2s. - 8%
phone idle - 12h 21m 51s - 5%
Bluetooth - 10h 12m 11s. - 3%
android OS - 19m 5s. - 2% -
I thought the battery life was questionable at first but now I realize that it was because was 'playing' with it CONSTANTLY. I guess the "new" has worn off and I used it more like a Phone today and my battery use seems good compared to previous smart phones I have owned.
What's eating your battery?

at 17h, 25m im at 61% with
display at 42%
Phone standby and idle at 22% each.
Ive been home sick so my phone hasn't been used much.

display - 68%
cell standby - 13%
phone idle - 6%
android system - 4%
android os - 4%
those are my top 5, I took my phone of the charger at 7 am, it is now 7:40 pm, and the phone is screaming at me telling me to plug it in.

display-43%
voice calls-32%
cell standby-11%
phone idle-7%
android system-3%
mario live wallpaper-2% wow
android os-2%
android core apps-2%

Live wallpapers are cool and all but they really aren't practical.

^ 2% makes them not "practical?"

looks like "display" is a trending topic...lol

Here's mine (52% battery remaining)

solved my problem i think
I've had problems with my 3g connection being quite choppy and only getting 1 or 2 bars since I got the phone. It must have been using a lot of juice in it's struggle to maintain 3g. I changed the setting to 2g networks only a week ago and Ive had a great connection to the Edge network. My battery now has 60% or more at 5p with a good amount of use. Before I would have to be charging my phone at 5p. Im looking into the issue some more.

Reasearch on LP idle battery drain

Premise:
idle battery drain in LP is much worse than in KK (1% per 1 hour vs. 3 hours.)
Personal experience : after disabling most of background apps in both OS's, the battery drain in LP is about 1% per hour, while it was 1% per 3 hours in KK.
New information:
I did a new test. I restarted the phone and charged it full. I then left it idle for about 6 hours.
Here are the results after 6 hours of a charged idle phone.

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Conclusions:
1) The constant wakelocks in idle state are due to S-Health app. They are not responsible for the battery drain.
2) Cleanly after restart, the phone drains the battery in idle mode at a rate of 1% per 3 hours, even in LP.
3) Something else is responsible for draining the battery at 3x the rate (of 1% per 1 hour.) This new culprit is only introduced on using the phone for a while.
I will continue testing this.
Any new ideas are appreciated.

The single biggest reason that I miss root is to figure out wakelocks on these things.

Someone posted a way to get Wakelock Detector working w/o root:
1) Connect phone to usb.
2) Do "adb devices" then do "adb tcpip 5555"
3) Open Terminal Emulator and do "adb kill-server" and "adb devices"
4) At this point, Wakelock Detector works.

Thanks for that info. I'll have to give that a try.

You can use wakelock detector without root, over usb adb

I have been seeing the same awake vs screen on behaviour, my fiance isn't seeing that trend as much and her battery life is better. I'm not complaining much about mine, but it could be better. I've tried clearing cache, battery pull, uninstalling apps, and changing sync settings.

Android Central published an article about the bad battery life on the S6. Samsung just updated the push service that affects the S6, S5 and Note series. Might be worth looking into.
http://www.androidcentral.com/galaxy-s6-battery-life-bad-update-might-help

I got wakelock detector set up with the instructions in this thread. It sort of works. It shows no Kernel wakelocks, and I think that it's very unlikely that my phone has had no Kernel wakelocks in the last 18 hours.

Yes I have been tracking this Note 4 with WLD for a couple months now and I haven't been able to pinpoit the issue of battery/wakelocks. It seems to be something very fundamental inside android itself. My wife's Note 3 absolutely does not have these problems. She can get 8 hours of screen time in a day. I am lucky to hit 4

Incorrect Battery Reporting | % Skipping | Dead @ 12%

Battery would fall 2% on the screen, it shows in battery reporting you can see the line drops steeply within 1 minute then stays stable (ignore the part where my device was asleep).
been very inaccurate with reporting % it randomly died at 12% (lowest its been since i got it 3 weeks ago) and when i power back on its at 2%. i charged back up to 40% and let it drop to 12% and the same happened.
i could live with the 3hr SOT if i got a good report of how much % was left so i can conserve usage if need be.
Running stock oxygen 2.1.1
then rooted and installed AK kernel (SOT is a little better) but still % dropping. i even super underclocked and saw the same effect
sent a ticket to OP - hoping its a defect and they can replace it

By what I read, it's a normal behavior when device wakes up from sleep.
It seems that, when device is asleep, even battery stats aren't updated, to avoid unnecessary drain. So, once it wakes up and you use it for couple minutes, android get a chance to record stats and update actual battery percentage.
Again, this is the explanation I read on such a question, and it does makes sense.

i managed to underclock enough to make the other percentages to show up - so it is working just i guess polling is slow.
the 12% dead battery isnt normal though. havnt had it since then but if reset a few times. now switched to a custom rom (keep loosing LTE) but ill figure it out, thanks!

can i ask you how you got all that info about the power consumption? an app?

Yes, its called better battery stats.

My battery life went down once I got Oreo. "Phone Idle" uses way too much battery now. Apparently, the only real fix (that I have found) is to do a repair on the system which will wipe everything. I am not ready to do that yet. If anyone knows anything different to remedy this without a wipe, please let me know.

I had the same problem when i updated to nougat. At night its drained more then 20% and the phone was hot. The stock battery stats showed nothing but that my phone idle is way higher then anything. I tried factory reset a few times, it was good for a time then its started again. The culprit for me was google play services/play store. When i deleted the update, everything was fine, when updated itself, battery went crazy again. Maybe you could disable it for a day, to see if its any better.

I will try this. Thanks for the suggestion.

My experience is that the battery life fluctuates heavily. Sometime it's (more than) okay, other times I feel the phone getting warm while it is in my pocket (with seemingly nothing running) the battery charge graph shows a steep dropoff when this happens... (I am using omnirom 8.1 - clean flash)

Hi! Did you ever looked at the logs / processes (adb logcat/top) during these dropoffs?

No. It happens mostly at inconvenient moments, but omnirom comes with matlog preinstalled, so I'll try to see if I can collect some useful data.

after factory reset battery life is much better, i mean i get from morning charge to evening before bed about 60 50~ % left, with medium use of phone, it lasts 2days with minor use ar even more easily, tho i do no gaming, only few apps, and most of apps i turned push notifications off , left on only for those i use, im pretty happy with battery now

but im having issue now, and dont know what it could be, battery lasts 100to 80 overnight with no use.... everything is the same, tho some app updates came in, like xperia sound equalizer and so... what could it be? dont want to do factory reset yet.... Last time i checked android os was not so power thirsty? It was used almost the same as screen just few percents above, and now it is. How to find out what processes is behind the android os?

Edit: in omni rom 8.1 i think i found solution , 1. in developer options set the mobile data always on: off 2.downgraded my play store to default settings and apk version (auto updates off) 3. i did set the adaptive brightness to off but it's optional. battery increased very much after that

LG G6 very short SOT

Hi, I have issue with my lg g6 .
The phone is about 1 months old but I reach very poor SoT max 2,5 h.
I check the main forum threads, but i cannot fix the issue
- I use the newest software
- greenify
- during this 2 hours I use only chrome/messenger/instagram
- it does not matter if I used wifi or data
- home app: home

install better battery stats, give it permissions via ADB.
Then monitor a full charge and see what partial wakelocks, alarms, processes are using your battery.

Hi I did, how you told.
I charged the phone up to 100% and left for 30 minutes without any use and captured following screenshots.
Do I understand correctly that the phone is always awake because of the lg gnss bloatware?

are you getting same battery life on lte and wifi
your lte signal looking too low
if it fluctuate a lot then it will take a lot of battery .

0% deep sleep

I don't mean to be glib, but the advice for battery issues is always the same (and mind-numbing basic):
1. Remove unnecessary apps
2. Factory reset the phone
None of the dozens of other tweaks mentioned here make a difference for most people.
And you can't do anything about signal strength.

I done some other tests after phone reboot and I becomed result with 87% deep sleep. But it does not matter if I used wifi or mobile data, the sot is always the same short.

I supposed that all the tweaks can barely help. I had hope that I could find some fix before reset the factory settings. In some way the phone is to be used and it is simply annoing the set the whole setting from scratch after reset....
But I think I don't have any other possibility (or I can wait for a Pie and hope for the improvement after the update)

Try to disable the WIFI and Bluetooth searching for improve the location. And then do again the test to see the deep sleep.

With accubattery app, you can estimate how"healthy" your battery is.
In normal usage, you would get about 18% of battery usage per hour with screen on, and max 1% with screen off

I made some tests with AccuBattery and the drain on screen on is unacceptable about 25-28%. The battery health is about 96%.

I use mcs magisk module with 90/80% config since day one with greenify + xposed module and after a year of relatively heavy use I'm still getting ~6h SoT (35% brightness). Maybe you should try to greenify some apps? Without root you have limited options though.
