Found some topic related to the com.android.phone wakelock.

http://xdaforums.com/showthread.php?t=2057093

The method to fix it doesn't seem to apply to s6 lollipop, but it be a direction worth looking into?

Sadly I'm not savvy enough with the Android system to find the fix... Hopefully someone can look into this.
[Galaxy S6 General] jacindc:
I've seen that too, and I have crappy battery life too. Went down 60% in five hours today with no screen time.

I am sure it has something to do with the cell radio and a bad signal. Doesn't drain badly when I'm at work or even out driving around with Bluetooth connected to my car - only at home, and pretty much requires Airplane Mode to be on to prevent it.
[Galaxy S6 General] dandrumheller:
Apparently so.

Definitely don't get crazy phone wakelocks and alarms like that.
[Galaxy S6 General] jacindc:
I just went into About Phone / Status and watched my mobile network entry switch every few seconds from lte to hspa+ to hspua. So I went to *#*#4636#*#* and set my cell network to lte only, and I can already see the battery life improving.

(Lte has 4-5 bars. Shouldn't be cycling like that.)

Can't leave it like that always, but it's a very good data point.
[Galaxy S6 General] PunishedSnake:
mine stayed on lte the whole time unlike the m9 which cycles hspa and lte
[Galaxy S6 General] scarchelli:
With location on highest accuracy, wifi on (4g when not on wifi) and brightness half way, I just got 3 days standby and 7 hours sot. Definitely happy with this phones battery. After a month or so of having it, it's been great. With location on I noticed almost no difference in life vs having it off. Also didnt notice 3g being better than wifi. And my usual super low brightness did only a little (~20 mins) bit to improve sot over the half way brightness just now.
[Galaxy S6 General] rajeshjsl:
66 degree celcius . damn . what are you running on that phone ?

It doesn't give you overheat warning ? I see around the net almost all s6 gives warnings around 57 (134 Fahrenheit) .
[Galaxy S6 General] ZoZo-:
That's really amazing! I tend to see a big difference in battery life if I have locations on all the day but I do think I have an app eating the battery with checking my location from time to time.. I do wonder which app tho...
[Galaxy S6 General] gashishpetim:
Hello to all of you,

I want to know about my phone purchased as Swiss S6, why me more than 3 hours battery display remains lit not by much. Is the problem in my phone battery or the Android software.

I see much to you that you are told to 7 hours SOT screen on time, and I more than 3 hours I can not
[Galaxy S6 General] qkevinto:
For those using GSAM Battery Monitor, if you're getting oddly high Wifi Active power usage report, like 30% ~ 50%, it may be because GSAM is retrieving the wrong Device Power Profile value on the Galaxy S6 for wifi.active.

In GSAM, if you go to Preferences > Device Power Profiles > Edit Power Profile , you can see that it may be using a value of 2,761,200, which is highly incorrect.

These are the correct Device Power Profile values, retrieved using Power Profile:

}

You'll notice that the correct value for wifi.active is 767. Make the changes in Edit Power Profile screen in GSAM by entering the correct value (check other values as well), hit Save at the bottom of the screen and check "Enable Custom Profile" on the previous screen. Head back to the summary screen, tap on the 3 dot and hit Refresh. Now you'll see some more sensible Wifi Active battery usage percentage.

Wether these percentages are accurate or not is another question but at least now you've got a more accurate reference.
[Galaxy S6 General] Synyster06Gates:
lol! That makes more sense. I looked at it and it was saying WiFi was using 50% of my battery and that the apps were using -8%. Completely logical. :rolleyes:

Now if I could find out in the Android OS/Kernel are draining my battery at ~3%/hour with no SOT I'd be happy.
[Galaxy S6 General] PunishedSnake:
Mine never gave me a warning

But it happened when using the camera, multiwindow or just general surfing
[Galaxy S6 General] greglord:
Please, just tell me if this is normal:

- at 8:00, unplug from wall charger at 100%

- data off, wifi on, location history off, lots bloatware disabled

- at 11:00, 78%

- at 18:00, 20%

this is more or less, without touching the phone. Battery usage shows "normal activity" with Android System on #1.

Should this be okay or should i just reset to defaults and start from scratch?
[Galaxy S6 General] Japultra:
Definitely not normal. What apps have you installed? It sounds like a rogue app taking up all your battery.
[Galaxy S6 General] greglord:
Skype, WhatsApp, Viber, FB, Twitter,... nothing special. Battery window shows Android System as #1 and that's about it. I've also installed GSAM Battery Stats and I hope it will show me something there...
[Galaxy S6 General] Japultra:
Facebook is a known battery hog, but it shouldn't be anywhere near this bad. Are you mostly in good signal areas or do you generally get pretty poor signal? Are you on Wifi or network data?
[Galaxy S6 General] greglord:
Thank you for replying. My signal strength at work location is 2 out of 4 bars (Status shows: -113dBm 0 asu). Network data is disabled completely. Wifi is on and connected.
[Galaxy S6 General] Japultra:
Just FYI, the signal strength indicator on most firmware is broken. It will ALWAYS read -113. This is not the true signal strength.

Your battery life should not be as bad as it is. I would try and find out what is causing this. If that avenue doesn't work, I'd do a factory reset or even flash new firmware. My phone lasts me 24 hours easily. In fact, my GSam "Averages Per Complete Charge" data shows me as having 1 day 9.1 h of average battery life with 4h18m SoT (I do put my phone on airplane while asleep though). It would be even better than this if my office had wifi.

Also, you might want to try turning off Google Now: http://www.sammobile.com/2015/05/19/having-bad-galaxy-s6-battery-life-blame-google/

What's wrong with my phone? 100%wake time
[Galaxy S6 General] gorilla p:
Try using wake lock detector to see what is causing your phone to stay awake.

If you're rooted, try using greenify to hibernate nonessential apps. If you're not rooted, get rooted.

https://play.google.com/store/apps/details?id=com.uzumapps.wakelockdetector

Once you're rooted, check out the optimal battery life document on bit.ly/makostuff. Its mostly for the Nexus4, but there's good general info in there too.
[Galaxy S6 General] Squintz:
Wakelock Detector doesn't seem to work on my S6. I'm rooted, but it doesn't show any apps. Says permissions have changed and requires root.
[Galaxy S6 General] dandrumheller:
Not sure if this really belongs here or not, as it doesn't seem to be having an adverse effect on battery life. It's not getting reported in total awake time in gsam, or at all in BBS. I don't know what is causing it, or what to make of it, other than it makes it awfully hard to diagnose other causes of battery drain. I was not playing any music today, at all.
[Galaxy S6 General] dandrumheller:
Already done, twice. Keeps coming back. I recently added a new alarm clock app, I'm guessing that might be the culprit. It's the only thing I can think of that I've changed recently that can control audio and display. Certainly appears to be a rogue app or process to me.

What's strange (or maybe not since it doesn't seem to actually be killing the battery) is that it doesn't show up at all in BBS. I saw a comment recently about something in GSam not being correctly calibrated for this device. It wasn't this particular item, but maybe other reporting things are messed up too. Haven't had time to go back and hunt it down again.

Edit; went back and monkeyed around with poweramp last night, making sure I exited it cleanly. Mediaserver is quiet so far today.
[Galaxy S6 General] J-Hop2o6:
Hmm, weird. And yea, battery reporting on this device is iffy with the apps. I drain ~1% per hour when the phone is sleep. I want to find out EXACTLY what's causing it, but nothing is really pinpointing me what it is. It might just be cell+wifi draining it mainly while its sleeping. On my last phone it will drain 1% per hour sleeping. And other times it won't drain for a few hours. But with the SGS6, it's ALWAYS draining 1% per hour sleeping, no matter what. Can't wait for the next big update to 5.1.X
[Galaxy S6 General] Hemant:
Completely agree. Battery is very iffy. At days it will drain badly while on days it will be great. There is no set pattern to it. I am on dual sim G9200 was installing custom rom over the last one without wiping data. Battery to be honest sometimes used to give 2 SOT to 4 SOT with similar usage and poor 4G signal all the time.

Yesterday i have wiped data and install the rom again with restoring apps + data using TB. Had crazy drain again realised that google fit data was syncing all the time. After disabling that currently on 17 hours with 3.55 SOT with 35% battery remaining. Will again monitor in the next cycle.

Its a great phone and i love it but just wish battery was more consistent on the better side.
[Galaxy S6 General] HYKwan:
We can install the custom roms on our g2000?

Can anyone pls tell me wt is this keeping my phone awake?
[Galaxy S6 General] Hemant:
Yes please refer to the galaxy duos thread. All info in that thread.

Are you rooted?

Galaxy S6 Battery Life

Here's what I noticed with my battery life, charging with the fast charger gets my phone sort of hot, but obviously charges quickly. The thing is that when I go to a full charge using my fast charger it also drains quick. Now when I charge my phone to a full charge with a regular Samsung White(S4)/Black(S3) charger my battery life is outstanding. With me being some what of a hardcore user always being on my phone when I go to a full charge using a regular Sam charger I can go all day with no problems. That's what I been experiencing with my battery life.

i have disabled google now, gogole search app, s health, google backup transport, google contacts sync on g920i, but "google services" is the biggest battery consumer.

Battery stats shows, 25% is consumed by "google services".

Not sure why it's still the main culprit. Anyone else having this issue?

Any tips would be greatly appreciated.

btw , i am running version 7.3.29 1866531-440 of play services.

[edit] i am still stock, not rooted.
[Galaxy S6 General] msavic6:
Anybody looked into why Google Services is such a battery pig on mobile data but non-existent on WiFi?

I leave my phone overnight connected to WiFi for 8 hours and barely 2% battery is gone in the morning with Cell Standby being the largest consumer.

The moment you switch to mobile data is the moment Google Services and Messenger decide to decimate your battery. I really can't understand Googles inability to solve the issues behind Google Play Services, I have almost reached the point where I'm going to disable it.
[Galaxy S6 General] rajeshjsl:
Sync is manual , 33% brightness , some gps (10 min) , some browsing (1 hr) , some camera pics (10min) , some video recordings (5 min at 60fps) , total 80km to and from airport , half hour calls .

some youtube , some music . Pretty good for my usage .

These days, I get between 5-6 hours of Screen On Time. It gets better with use. Just make sure to turn off Google History Location. My main annoyance is the 1% per hour drainage while the phone is sleeping/idle. Still can't pinpoint that. Plus, I can't use Amplify (requires xposed) to limit Google's NLP pinging.

Fast charing is to good to be true. Hence it's probably damaging to the phones battery and detrimental to battery life over the long run

Try only using it when you must

Charge your phone with a regular 2A charger over night.
[Galaxy S6 General] msavic6:
I have yet to use fast charging with my S6. I simply charge it with a regular Samsung 2A charger and it charges in an hour and 15-30 minutes.

In my case, I don't need it to charge any quicker than that, I rarely have to top up my device during the day and if I do, the regular charger is fast enough to give me enough juice to last the day.
[Galaxy S6 General] YaviSGS:
Updated to the latest firmaware. Great battery life.

What firmware are you using my dear Dutch friend. And most importantly, where did you get it?
[Galaxy S6 General] lowjinyik:
For those with not very good standby times on 4G/3G, I think it's due to fast dormancy. Anyone knows how to toggle it on the S6?

Day 2 of using the S6 and coming from a Note 4 I'm especially spoilt, obviously the battery on this is not as good as the Note 4 but I'm seriously hoping it improves...if it wasn't for the fast charge I'd be well annoyed! Only down side to this phone as everything else is amazing!!
[Galaxy S6 General] BlackSnowflake:
First few days I felt the same coming from S5. But I was mostly installing apps and rebooting the phone. Now that some time is passes i feel confident in s6 battery. I get consistently about 4h SOT Which is enough of staring at phone screen for one day in most cases :)

Try lower brightness usually auto brighness makes it too bright wasting energy :)

S6 is a fast multitasker so shorter time on screen is needed to get the job done anyway. Very fluid.
[Galaxy S6 General] wevocy:
Yeah data connection is the culprit. Had it off all day and now at 80% battery after 14 hrs of use
[Galaxy S6 General] ra9b:
Yeah I noticed that it took around 5 hours to fully charge! I may try it at when I sleep and see what happens.

Hello, just wanted to share my recently acquired battery stats! At first opinion this phone was not great at battery as most people have probably heard from reviews. But once you let it settle, see for yourself!!
[Galaxy S6 General] assasin34:
with %10-15 brightness:)?
[Galaxy S6 General] butthurtlocker:
30% on average has been my most used brightness setting. I almost never max it out, maybe like 30 minutes of that is maxed out, but its such a bright screen i never need max. But yea still not too bad for a QHD with that measly battery!
[Galaxy S6 General] maverick1103:
I do run the brightness low, anyhow I'm quite reserved at the moment because I've only had the phone 2 days so far.
[Galaxy S6 General] DeMi-GoD:
I agree. The screen is so easy for me to pretty much always see right around 40%-50%.
[Galaxy S6 General] Hemant:
But for me it seem the battery life is almost same whether on fast charging or my old Note 2 charger. I only get around 4 SOT. Battery drains as i know i have a crap 4G signal but still the standby battery is worse.

I have installed greenify till it allows me to use without xposed installed.
[Galaxy S6 General] benjmiester:
Yeah, I can attest that slower charging/other chargers will not help/affect battery life as some have theorized. I left my OEM fast charger at my Dad's place in Pittsburgh when I went to visit last week (I live in Dallas). So I have been using an old Samsung 1.5a charger for about a week. It makes 0 difference in battery life.
[Galaxy S6 General] szjeng:

My LG G2 doesn't have that technology, isn't fat, manages to get almost 2 days of battery. Anyway, this device bewitched me!
[Galaxy S6 General] 1iam5mith:
How many cycles does it take for the battery to be alright? Because I got my s6 yesturday, fully charged last night, its been off of charge for 46 mins, with 22 mins SOT, and 84% left. My iPhone 6 Plus with the same usage today is on 100% still...
[Galaxy S6 General] Hemant:
i think should take at least 3-4 charging cycles. Also by that time you would know that the battery is draining rapidly and you will start looking for clues to maximise it by turning off wifi scanning all the time, VoLTE if you have it, disabling samsung apps etc etc. :):silly:
[Galaxy S6 General] BlackSnowflake:
How much was your battery charged when you started the phone for the first time out of the box? I guess that it should be around 50%?
[Galaxy S6 General] 1iam5mith:
Mine came with 50%, I used that up then full charged overnight
[Galaxy S6 General] myd.:
Mine came with around 40% battery out of the box. Is something wrong? My screen is on almost no brightness nearly all day.

It does? It does decharge rather quickly though, there hasn't been a day that I didn't charge it 2 times,but I guess I knew that would be the case, and it doesn't bother me that much due to the fast charging..

It should last you a day on a full charge with about 4 hrs of SOT if everything functions normally and there isn't an app that's keeping your device awake.

Also I found that the rom needs to settle a few days until you get a realistic representation of battery life.

Check out better battery stats to find wake locks.

[Galaxy S6 General] tuk1maar:
That's not what's supposed to happen since the GS6 should last just as long as the iPhone 6 Plus. For instance, my older Galaxy S4 would have around 1 hour and 10 mins of screen on time on autobrightness with 84% battery left.

For your information, the iphone 6 Plus' battery indicator is wrong. It's just like the LG g3 which also does that. usually with around 20 mins of SOT it still stays at 100% battery... and afterwards you'll see it dropping when you won't notice it.

Is there a way to stop Google Play Services from draining y battery? It is draining it like crazy! :(
[Galaxy S6 General] :
Some would say this turn your phone into a dump phone.

But I don't use ANY google apps (disabled all of it.) - (using stock email app) and maps works fine. I just greenified Google Play Services with root and cut wake up path.

That way, it only starts when I use the phone (actually whatever i do, it starts out of nowhere) but it's hibernated when phone is in deep sleep. I got Google Play Services down to 0.1% drainage (GSM battery monitor)
[Galaxy S6 General] maverick1103:
Everyone keeps going on about how the iPhone 6 Plus' battery is better, well I'd expect it from a gigantic phone.

I've just come from a Note 4 mainly because it was too big, great phone and decent battery life, but you can't compare the iP6+ to the S6.
[Galaxy S6 General] bloodrain954:
The battery life is alright at best. Anyone who tells you otherwise is simply trying to justify their purchase. I like my phone, but the battery lacks for sure. So much for those Samsung commercials making fun of Apple users always being around a charger.
