I always turn off my wifi/3g/lte unless when i need it. When I want an update on what happened on facebook etc i just turn it on and i get everything withing 10 seconds. Those 10 seconds save you a lot of battery power and radiation ;)

Hi folks,

Is it normal that Gmail tops my battery usage list? Even higher than my SoT....
[Galaxy S6 General] FSOP:
Yup.

Battery is nowhere near as good as my OPO (to be expected with the massive difference in capacity) but it more than gets me through a work day easily, so I don't mind.
[Galaxy S6 General] bkeaver:
I would boot it to safe mode just to see if it still doesnt sleep. Dont start any app that you have downloaded at first then if you are seeing that its sleeping start an app see if it still sleeps then keep repeating it. Its the only way i know to do it without root and not having to uninstall your apps.

Battery drain from cell standby is 1% at end of my whole work day on my Bell Canada sku S6, so it's not design. I even have bad signal here...

Either firmware, or very bad signal zone I guess...
[Galaxy S6 General] tiptop10:
Just got the GS6 this morning and have been observing battery. Using the phone doesnt actually drain the battery much but the main concern I'm seeing is sleep/idling. My phone shouldnt drop in % after half an hour with the screen off with no background tasks but it does. At least it seems like it can be a OS issue that can be patched to give the phone better battery stand by time.

That's the first 5 minutes of using my phone today when I took the screen shoot. You should look at the Averages Per Complete Charge stats...

---------- Post added at 10:18 AM ---------- Previous post was at 10:12 AM ----------

You can just turn off your phone completely and let it charge till its 100%. Turn on the phone again and let it charge to 100% (even though it says 100% charge). Thats it...

[Galaxy S6 General] POLO_i780:
Some shocking results here, not much Samsung can do to up the batt life though without taking something away.

The Nexus 6 and Note 4 have good battery capacity to display ratios thats why they get much better battery life, the S6 on the other hand has an even smaller batt than the S4, battery life is bound to be average at best, I don't think I have seen anything more than 4.5hours SOT when looking at peoples S6 results, but hey...it is early days.
[Galaxy S6 General] Prod1702:
Man coming from a N6 which I know doesn't have Note battery life, but it was better then my S6. I have only had the S6 now for a few days but the battery is crazy bad. I am rooted with close to everything frozen with TB that I would never use. Wifi calling and Wifi always scanning is turned off. I am not willing to turn off VOLTE because I use it and like it. Today I streamed Pandora for about 2 hours, maybe played about 15 mins of Boom Beach, rest has been text and web browsing. I ahve 2:07 of SOT with brightness set to about 35%, and I am at 33% battery left. I hope to god battery gets better over time or this will be the worst phone I have owned for battery.

Edit: also to add does this phone go into deep sleep for anyone. In the last 8 hours my phone hasn't gone into deep sleep once. It just seats at 400 mhz. :( man I hope they do something about the battery with custom roms or Samsung fixes this ****.

Cell standby has disappeared for me. But Play Services is killing me... Can't figure out why.

Verizon variant
[Galaxy S6 General] Jerry1130:
The standby drain on my Verizon phone was completely attributed to wifi. Try to turn wifi off and see how you do.
[Galaxy S6 General] Prod1702:
what all did you disable to get this. I have disabled wifi calling / wifi scanning. I am not willing to disable VOLTE if thats what you did but would like to know if you did. Cell stand by is still killing me big time.
[Galaxy S6 General] POLO_i780:
Try dropping screen brightness to around 30%, also go to Accounts and ensure Google isn't syncing unnecessary stuff and Google Settings, they have been adding all kinds of stuff these past few weeks.
[Galaxy S6 General] jntdroid:
I'll tell you what I did if you tell me how to get Google Play Services under control... ;)

TBH, I'm not sure what I did, though I think [MENTION=4009245]Jerry1130[/MENTION] might be right as I've been on cell data all day today and was on my home wifi all weekend.

Last night I disabled cell data and disabled VoLTE, and just stuck with my home wifi until I went to bed. I had planned on testing today like that - no VoLTE, connected only to my work wifi (which is spotty, sometimes good, sometimes not). Then this morning when I topped off the battery, I decided that was ridiculous, I shouldn't have to gimp the phone to use it. So I turned it all back on and stuck with cell data and no wifi at work. So either the toggle got rid of it (which I doubt) or it's directly related to wifi as [MENTION=4009245]Jerry1130[/MENTION] said.

So, now, Play Services... ;) Actually what's weird is Android System is my second highest under Google Services, and it, too, might be worse when wifi is on. Hopefully Wifi isn't just pure crap on this phone, as I've had some cell reception issues as well.

[Galaxy S6 General] kinghu:
Much better after 3-4 cycles. Consistently around 5 hours SOT now.

I don't have any power saving or significant things disabled. Auto brightness, GPS on, BT on and syncing to my Garmin Vivosmart (also securelock detection). Mixed wifi/4G use from 9am to 2am. Out on 4G until 2pm doing emails, browsing, WhatsApp, photos and videos. Then back on WiFi watching a few TV episodes from the internal memory plus a few hours streaming YouTube 1080p with more email, web, fenix, WhatsApp, SMS, Tapatalk thrown in.

No complaints here as I'd usually not use it as much as this.

Battery life got even better in 3rd drain

You guys in US are getting terrible battery life with high stand-by drain for some reason. I just want to confirm that it isn't a hardware issue but more like firmware issue. I have an Indian variant(SM-G920I).

Usage: screen brightness variable throughout the day, 100% with Auto boost in sunlight and 0% for night reading. Usually 25-30%. No power saving on. WiFi on the whole time, except 1-2 hour when I was on HSPA+. Watched 2 episodes of Game of thrones( one in 1080p, other in SD), YT for 2 hours, Browsing for a lot of time and music streaming for hours. It was an extremely heavy use and this thing doesn't die.

Let the screenshots be the judge.

P.S. This thing lasts forever in stand-by. I slept for 3 nights for 5.5,6, 7 hours and it drained 0%, 1% and 0% respectively. Maybe it's going to deep sleep, at least for my variant.
[Galaxy S6 General] Ngster:
Is your GPS location set to GPS, Wifi, and mobile networks OR Wifi, mobile networks OR GPS only? I want to keep location on, but use the least battery intensive option
[Galaxy S6 General] kinghu:
GPS, wifi and mobile networks.

I wanted to see what it was like without any cutbacks.

Averaging about an hour less than my Note 4 got with the same usage pattern is very acceptable to me given the smaller battery and screen/SoC combination.

from my S6
[Galaxy S6 General] omersak:
I have the problem of no deep-sleep too, and it's mostly attributed to Android OS in the built-in battery settings, and Kernel in GSAM. WiFi and location off - for the first time ever in the history of all phones I've owned, I even stopped exchange sync and deleted the facebook app just so his royal highness can go to sleep better. Nope. Don't know how to go about it without rooting and voiding the warranty now but I'm tired of this battery anxiety and am looking to sell the phone - which is a shame because I absolutely love the phone to bits.

I do have a method to 'force' the phone to go into deep-sleep though, with location and sync both on. I restart the phone and and use SmartManager to "Clean All", and then lock the phone. Get the phone to go into deep-sleep for around 80% of the time and it drains battery at 0.9% per hour - how it should do.

Trouble is, as soon as I start using my phone (Chrome, whatsapp, messaging) after a bit the stay-awake disease returns - so I have to repeat the procedure again if I want it to stand-by as it should. The wake lock never goes away until restart, even if I go into airplane mode and turn everything and sync off. This exact same pattern has repeated upon many factory resets. So I don't know what the problem is.

Anyone with root figure out what causes the wakelocks?
[Galaxy S6 General] WhiteHartMart:
My phone goes into Deep Sleep perfectly according to BBS. What I don't understand is losing 30% battery overnight - BBS reports 3.5% drain per hour!

Previously I've had phones only lose approx 5-6% overnight - starting to think my device is faulty?
[Galaxy S6 General] belloni:
Anyone help?
[Galaxy S6 General] benjmiester:
Sounds like it may be an issue with wifi calling, as most people are disabling that for signal related battery drain. I noticed there's a "voice over LTE/VoLTE" setting in phone call settings, maybe try turning that off? Possibly just low signal? That will keep the phone searching for a better one, and that causes drain.
[Galaxy S6 General] belloni:

Hey all!

I've just switched over from iOS to Android (used to be an Android user back in the HTC/Desire/Samsung Galaxy S days and absolutely hated the phone back then haha. Am loving this phone but the battery is seriously not what I expected! I'd say I'm an average user (some phone calls, some social media, photo taking, browsing, occasional video watching) but my battery is being hammered and I'm not sure what by! I'm in the UK with Three and so although there are others who have had success by disabling VoLTE, I don't have that option so I'm wondering what else I can possibly do. I tend to disable location unless I badly need it, and generally use wifi where possible.

I can't post images as I'm a new user but my battery is currently at 40% with only 1hr 38m screen on time... for some reason Facebook has used 11% despite only being on it for less than five mins. GSAM battery says 38% sot but 11.9% consumed by Android system. I downloaded CPU spy but I'm not really a tech head so I'm not sure what most of it means but my deep sleep is only at 46% so am not sure if it should be higher or lower??!

Only "tweak" I did was disable some of the Vodafone Carrier bloat.
[Galaxy S6 General] tiptop10:
how would you say it holds up compared to your 1st cycle? massive improvements ? and did your standby improve as well?
[Galaxy S6 General] Gboss01:
My initial 1st full charge got me about 18hrs and 3hrs SOT.

I have noticed an improvement in both standby and SOT.

Admittedly because my phone is new I have been using it a lot. Testing out games and apps to see performance.

I should see even better battery as my usage patterns return back to normal lol.
[Galaxy S6 General] eyc:
To be precise, it's a 3% drop over 7 minutes, not 5 minutes. While the video itself is 5 minutes, the time on the phone elapses 7 minutes, suggesting that the edits to the video removed some of the reviewer's time handling the phone.

If we assume the battery diminishes in a linear manner (which I know it doesn't), that would be 233 minutes to drop from 100% to 0% (i.e., 100 / 3 * 7), which would translate to 3.9 hours of screen on time. No idea if that's good, bad, or average.

I assume the regular use may be able to give a it more juice. However, if we notice Samsung is not vouching the battery life if S6 as such but

more on the fast recharge and wireless charging capability, which I think is to lessen the worry of a lower battery life.

Huh, ultra power saving mode is BS, how so? I have went with only 3% battery left for six hours before, until getting back to a charger. UPSM works as supposed to me...

I do hope Samsung's claims are true, and it exceeds the battery time of the S5, would be great if it could double it!

[Galaxy S6 General] SilentEYE:
The screen will still eat most of the battery. Therefore there will be no doubled battery life of s5.

The screen efficiency product cycle from s5 to s6 is too short and there is a resolution difference, still.
[Galaxy S6 General] se1000:
FYI, the S5 LTE-A had a QHD screen and had similar to same battery life as the FHD S5
[Galaxy S6 General] SilentEYE:
[MENTION=3660377]se1000[/MENTION]

I know that the QHD S5 had nearly equal battery life.

The step from note 3 to note 4 was quite similar to the step S5 --> S6 and there was only 2 (max 3) hours more battery life on note 4.

Therefore I think it's clear that the S6 will not double the S5 Screen On Time.

Samsung itself even didn't talk about 20 hours SoT.
[Galaxy S6 General] se1000:
I don't think it's very similar. Note 3 to Note 4 we were talking about a 28nm process for both processors, same type of RAM, etc etc. While I agree that we will probably see nowhere near a 2x improvement, I'm still holding out hope that Samsung has optimized battery life to be a bit better than the S5.

Also, I thought the Note 4 gets much better than 3hrs of SOT!
[Galaxy S6 General] tenxo:
I meant double screen on time of the s5, not double the claimed S5 times overall from Samsung. I see you understood that though in you response above to the other poster... Still we don't know how efficient they have made this thing, so was just hoping!

[Galaxy S6 General] msavic6:
The Galaxy A7 has a larger screen than the S5 and only has a 2600mAH yet manages too achieve roughly the same battery life. GSMArena posted an 83hr result with it, that's 10 or so hours higher than the S5 on kitkat and on par with the S5 running lollipop. There is a difference in processors between devices but both of these processors are still more power hungry than the 14nm Exynos inside the S6.

Keep in mind, that's not a top of the line flagship and I doubt Samsung even gave a fraction of the engineering effort it spent on the S6's optimization towards the A7.

With that said, I don't think it is unreasonable to expect the S6 to exceed the S5's battery life even with the deficit in battery capacity. The worst case scenario? it matches the S5 in battery life which had fairly good battery life to begin with.
