[T-Mobile Samsung Galaxy S6] Divine_Madcat:
It may have helped, but since i dont use any of the Samsung service, i wound up disabling it.

As it is, my battery life is more than passing right now. 1D, 9H, 36M on battery, still at 29%. This has been regular use, including:

Texting

Web Searching

Music (Poweramp, driving Sennheiser HD558)

Android wear connected

Took several photos

A 20 minute walk with GPS recording

Ill take a final screenshot when i slap it on the charger. But for my average use, i will have made it through two business days, which is more than good for me. It think part of it is giving Android some time to get itself squared away, and the other is updating (manually) the google play services (7.3.29)..
[T-Mobile Samsung Galaxy S6] se1000:
Totally agree. First full day for me but my results are similar. Also, the new phones seem to come with OCG
[T-Mobile Samsung Galaxy S6] ThePagel:
The push services update supposedly fixed some wifi issues and cell standby. Its good to hear battery life for you is better than my g3. Would you happen to know if google plans on pushing the play services update to more phones? Hasn't that been a problem for wakelocks since kitkat or even ICS?
[T-Mobile Samsung Galaxy S6] Divine_Madcat:
Sorry, cant say i know anything more than the general public on that one. But since the APK's are out there, i would just grab them and update manually.. No harm that i have seen.

As promised, here is my screenshot; 1D, 14H uptime. I don't know why the battery stats don't show it, but that is around 3-4 hours screen time (i have a different battery app now, but it didn't catch the first day, so...). The decline today was jamming to several hours of music while working. As it is, i really cannot complain; i dont think my S4 ever did this good. I know have confidence i can pull off an extreme day with power to spare, and that is just fine for me...
[T-Mobile Samsung Galaxy S6] PunishedSnake:
Those with better life after push service and play services updates did talk disable WiFi calling and volte
[T-Mobile Samsung Galaxy S6] km8j:
Where are these updates coming from?
[T-Mobile Samsung Galaxy S6] PunishedSnake:
Play store
[T-Mobile Samsung Galaxy S6] raw2000j:
The dam cell standby draining battery I hope they fix this soon
[T-Mobile Samsung Galaxy S6] 499:
If I disable location my battery lasts all day. wifi and volte helped but not as much as the location.
[T-Mobile Samsung Galaxy S6] RobbyRob:
So does 5.1 fix these issues? I can't have a phone that does not last all day. I think the Galaxy S6 is the best phone I have ever used, but the battery is killing me. I don't mind putting it away for a few weeks if 5.1 solves all these battery issues. But I want to return it if the update does not fix them.
[T-Mobile Samsung Galaxy S6] freebee269:
flash this in recovery, will fix the deep sleep issues permanently.

I'm me conserved with the memory leak madness this phone feel like a 1gb ram phone
[T-Mobile Samsung Galaxy S6] Singin' Bluebird:
This is getting ridiculous. I turned on ultra power saving mode and the phone still drains the batter quickly. I dropped about 10% in less than a class.
[T-Mobile Samsung Galaxy S6] ipaq_101:
Yeah I am disappointed with the battery life as well, I have to plug in on my drive back home. lollipop has been full of bugs from the onset, that's the problem with a free OS I guess there is no urgency to fix anything quickly.
[T-Mobile Samsung Galaxy S6] dc82:
The problem with an open OS is fragmentation. This OS is supposed to be "optimized" for all of the devices that in it. Google can ether keep it open source and keep the modders happy or close it up and bring it closer to perfection. Can't do both, so pick your poison.

[T-Mobile Samsung Galaxy S6] Divine_Madcat:
The problem is, results like this are not normal. At the risk of bragging, here is a recent shot from my s6 (location disabled, AW watch connected, no power save, ~3H screen time)

Aside from a factory reset after the last firmware, and disabling junk apps, the big boost for me was making sure i was running the latest play services build.
[T-Mobile Samsung Galaxy S6] ipaq_101:
Can you list the apps you disabled? I have the latest google play services installed. My main problem seems to be location, the damn thing is always searching for a location, maybe I will turn this off and see if it helps.
[T-Mobile Samsung Galaxy S6] Divine_Madcat:
I doubt most were causing problems, but since i like a clean app drawer, here is what i nixed:

Amazon

Briefing

Chrome

Facebook

Galaxy apps

Galaxy Apps Widget

Google Play Books

Google Play Movies

Google Play Newstand (these three i am sure aren't causing issue, i just don't use them...)

Google+

Hancom Office

Hangouts

Instagram

Lookout

Messenger

Milk

Milk Video

Onedrive (this was using some network traffic, but wasn't a huge killer)

OneNote

Samsung Push Service

Smart Remote

T-Mobile Name ID

T-Mobile TV

Whatsapp

All the disabling that people are having to do to me is the problem. A $700 device with all the technological advances it has should not need to have to have some of its features disable in order for it to run optimal. My nexus 6 doesn't need to have to have all this stuff we need to disable on our gs6 to run the way I want. I know the nexus 6 has a bigger battery but the battery drains are not nearly as bad also. Samsung should have put in a bigger battery or better optimized the phone hardware with the software. I can't help but think the cell standby issue is where Qualcomm expertise shines here. They have a better radio that's more optimized with u.s. carriers than Samsung's. The nexus 6 uses a snapdragon 805 and has no cell standby issue. Even when the gs6 gets upgraded to android 5.1 I am betting people will still need to disable various Wi-Fi and volte stuff to get better battery life because the hardware in the phone won't have changed and radio will still be the problem. Disabling all this stuff to get better battery life doesn't fix anything it just masks the hardware issue at hand.
[T-Mobile Samsung Galaxy S6] Divine_Madcat:
I know what you are saying, but dont confuse disabling apps, with disabling features.

The only real FEATURE i have turned off is location, simply because i don't need it. (and can turn it on at a flick of the switch) Features that i have left ON at this point:

Wifi

VoLTE

Auto brightness

Bluetooth

etc...

Now, i do have tons of junk programs turned off, and would have never had them installed had i had the choice -but most were disabled because i don't want then running at all, not because they were the source of a serious problem. I don't use facebook/twitter/instagram/whatsapp/hangouts in my life (i guess i am boring.. sigh), so i don't need them running at all. I am sure other users can run them with minimal impact. Same for lots of the Samsung apps.

From where i am right now, i am getting better life with my S6 than i ever was with my S4; i would have never pulled two complete days off the charger, with use... I hate seeing people have problems, and i DO think there is a bigger issue at heart.. i just wish i knew what i could advise to help people in general....
[T-Mobile Samsung Galaxy S6] CalbinR:
Average battery?

Just wondering, what is the average SOT and standby time you guys are receiving?

I was receiving rather poor SOT and standby times so I followed the advices that had been posted on this thread.

However, I am unsure if whether or not my issue has been fixed. because GSAM gives me some rather absurd percentages (is anyone else getting this problem?).

Considering returning the phone and hoping it doesn't come to that.
[T-Mobile Samsung Galaxy S6] H3adru5H:
I got no issues with battery life.
[T-Mobile Samsung Galaxy S6] sublimaze:
No complaints here either
[T-Mobile Samsung Galaxy S6] abachhan75:
after couple of weeks of use , after resetting the cache, i can also confirm that battery life is as good as my old S4. i keep location and bluetooth off unless needed. also turned off VOLTE and wifi calling.
[T-Mobile Samsung Galaxy S6] RobbyRob:
If only I could get those times on mine with wifi calling.
[T-Mobile Samsung Galaxy S6] IXChicharitoXI:
I'm going to purchase the phone today. Is it recommended to factory reset right off the bat?
[T-Mobile Samsung Galaxy S6] benjmiester:
I would call this excellent, considering I map addresses with accurate location on and use turn by turn, plus Voxer which has location built in to each voice message for work each day for about 7 hrs. You can see it really start to drop about 4pm when i go to work lol. I had it plugged in for a few mins to PC usb while transferring a kernel and then flashing it.
[T-Mobile Samsung Galaxy S6] CalbinR:
After turning off voLTE, wifi calling, and clearing cache, I have to say that my battery has improved exponentionally.

However, I am not sure if the standby battery drain I'm getting is normal. Over the course of 6hours, I lost 5% battery (wifi off). Is this normal?
[T-Mobile Samsung Galaxy S6] mikeyinid:
I don't usually get into these types of conversations, but this phone drives me crazy! One day battery life can be amazing, like 4 to 5 hours sot and 18 hours. Other days I'm on the charger after 9 or 10 hours and only 2 hours sot.. the only way I've found to get any sort of consistency is to disable volte, WiFi calling, and location. I can easily get 5ish hours sot and 20+ hours with that stuff off...But that's not the way it should be. I have to constantly remind myself how small the battery is..
[T-Mobile Samsung Galaxy S6] PunishedSnake:
Battery not as good as n6 but the same ish as the m7. What annoys me is the ram management

[T-Mobile Samsung Galaxy S6] mikeyinid:
IPhone 6, which I used for a month or so before the S6, was an all around great phone. It got pretty close to the same battery life as this with a much smaller battery.
[T-Mobile Samsung Galaxy S6] mikeyinid:
This is tonight. First time in weeks I didn't reboot 30 times testing tweaks haha. This is great, but like I said I have volte, WiFi calling, and location services disabled.

Yeah and when we see 5.1.1 most new people will be saying why does this thread exist this phone gets amazing battery life. I got over 6 hours sot today no mods no root, not bad. I'm actually wondering how many people are over freezing apps and making things worse.
[T-Mobile Samsung Galaxy S6] xdviper:
I'm getting really bad cell standby drain followed by Android OS draining my battery. Tmobile version here, I've done everything suggested, disabled volte wifi calling, don't even use wifi and I'm seeing drainage like no other. I've done a factory reset, cleared cache multiple times to no avail. Please help. Not rooted yet neither.
[T-Mobile Samsung Galaxy S6] mikeyinid:
The only way I've been able to get consistent battery life is to disable WiFi calling, volte, and location.
[T-Mobile Samsung Galaxy S6] xdviper:
Everything is disabled besides bluetooth which I need for my Moto360. Location, Wifi calling, VoLTE, and multiple bloatware is also disabled.
[T-Mobile Samsung Galaxy S6] Slicktune:
The battery on this phone is ridiculously bad, Look at my on screen time. ..this is retarded 3 hrs of screen ontime!! Jesus christ! And only a day of standby time, I've been getting that on my s4 before and even more on m8 (to the m8 users you know what im talking about) i should be able to get at least 2 days easily on the new "power efficient" processor and Amoled screen.. this is bull if i don't get 2 days of standby by tonight im returning this device to tmobile and jumping on the moto x 2014 sale $375 for the 64 gb... [emoji20] in so livid i could slam this phone but if i crack it i can't return it.
[T-Mobile Samsung Galaxy S6] Dr. Fed:
Why are you surprised? This isn't your first rodeo. QHD with a 2550mah battery, it's amazing to me it gets 3-4 hours of SOT. The processor and screen are actually very efficient, but the battery is small. Throw in some strange wifi calling/ cell standby battery drains...it's not shocking.
[T-Mobile Samsung Galaxy S6] se1000:
#1. chill. #2. If you're going to switch, the Moto 360 is a particularly bad one, the battery isn't very good and the screen is awful compared to the GS6. I recommend the Sony Z3 for you.
[T-Mobile Samsung Galaxy S6] Dr. Fed:
I agree that the Moto 360 screen is no good compared to the S6. What's that, like a 2 inch diagonal? :p
[T-Mobile Samsung Galaxy S6] se1000:
HAH! my bad I meant Moto X
[T-Mobile Samsung Galaxy S6] Slicktune:
See the issue is that everyone is getting fooled on what they "think" they should be getting in battery life. In 2011 ppl were getting up to 30hrs in battery life on their s2

Samsung should have fixed this issue its been F&$//ing 4yrs later and im only getting 27 hrs..?!?!?! thats effin bullsh!t im returning this dumb device tomorrow, i cant stand this any more, i should easily be getting 3 days of stand by... STANDBY not screen on...id be happy with just 10hrs of screen on time and 3days of stand by with only 12% left.. but no we have to get these crumbs of only 1 day stand by and only 3-4hrs screen on time and thats with most of the features off...sad world we live in that your all brainwashed to think thats ok...its not your faults its what they make u think is the norm or the standard...
[T-Mobile Samsung Galaxy S6] PunishedSnake:
so you are saying you have 5.1.1 ota?
[T-Mobile Samsung Galaxy S6] Dr. Fed:
True we are brain-washed. Also I can't get that silly voice out of my head (you know, the one you used in the galaxy s5 video you made). Whenever I read your posts, all the words, in my head, sound like that voice. :eek:
[T-Mobile Samsung Galaxy S6] Slicktune:
Hahah at first i didnt get it... lmaoo [emoji106] ill be making one soon about s6s battery or something
[T-Mobile Samsung Galaxy S6] ThePagel:
No I don't, I was just saying it should be even better for me and everbody else on 5.1.1.
[T-Mobile Samsung Galaxy S6] DC2CA:
It's not THAT bad but my work phone which I never use is an S5 and with power saver on it goes like 5+ days in standby when I leave it alone. I definitely expected more from the phone. Luckily I haven't had any long days away from power yet.
[T-Mobile Samsung Galaxy S6] benjmiester:
Why is everyone so concerned with over 1 day of standby (with being used, not just sitting)? For one is simply charging while you sleep somehow not an option? Also, ultra power save exists literally for this reason. Can still get calls, texts, and emails too. I'm not trying to flame, just don't see why this is an issue at all. I need some insight into the days you guys live with your phone.

Maybe some of you guys are living in the grand canyon or on a desert lsland or something? That's a joke, BTW. :D
[T-Mobile Samsung Galaxy S6] Slicktune:
You do know the battery has a life cycle and thats the main concern.... the more you charge it the less life span it has, "well if you don't know, now you know" *biggie voice*
[T-Mobile Samsung Galaxy S6] benjmiester:
Not within 5 years to a decade, according to tests/studies I've seen. One actually said charging more, and fast charging are actually better for lithium ion batteries as they keep the voltage up, and the only things that are known to damage them are decharging to low voltage levels (like keeping it off charge for days at low % lol, or running down to less than a few % or worse completely empty) and excess heat of course.
[T-Mobile Samsung Galaxy S6] ThePagel:
Let's just end this right now ;) http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
[T-Mobile Samsung Galaxy S6] benjmiester:
At the voltage our batteries typically run (2.55 volts) "2400 to 4000 cycles" that's everyday for 6.66 years to 11.11. Yeah, let's end this right now ;) Not to mention discharging it less means less to charge to full, ie less cycle. Also, the same place you link to has a study that shows that fast charging is good for lithium batteries, the article I mentioned before. Anyway, this is a non issue in reality. Who's going to have their S6 still, when the S12 to S17 is out? Come on now.
[T-Mobile Samsung Galaxy S6] ThePagel:
Well that's taking only charging into account. Everything you do with a lithium ion battery will lower its life. I'm not saying it's a issue, but realistically we are looking at more around three years of life.
[T-Mobile Samsung Galaxy S6] benjmiester:
Yeah I agree. Other factors are at play. Basically though, you should be good for many more years than you will keep the phone unless you let it get crazy hot (if you're in Dubai, guess there's no choice haha) or routinely let it run too low. But it would seem that quickly topping it up more often is better for it than letting it go for days until low. That's what this article was saying:

http://www.pcworld.com/article/2683...last-slow-charging-may-not-be-the-answer.html

I thought it was battery university, but turns out it was done by MIT and Berkeley teams, so even better.

Ultra Power Saving Mode

Hi, I'm certainly new here, but have one question and it's regarding UPSM on Tmobile Galaxy S6 compared to S5. When my S5 used to hit 10%, the indicator would tell me 24 hrs of battery left on my phone, wouldn't last exactlt 24 hrs, but close enough. However, my S6 indicator gives me much reduced figures at charge levels of 90% and above as well as never giving 24 hrs indicator once I hit 10% for Ultra Power Saving Mode. Am I the only one? Should I be worried? Anything I can do to fix it?
[T-Mobile Samsung Galaxy S6] benjmiester:
I wouldn't worry too much about what it quotes. Unless you're having the VoLTE or Wifi calling battery drain issues you should be able to do 24 + hrs unless you use a lot of SOT. That's only based off whatever usage it's had since you took it off the charger. Mine also says 16 to 18 most of the time, and I just went 24.5 hrs with 6 hrs 5 mins of SOT yesterday so it's definitely not too accurate. We tend to use the phone a bunch immediately after it's off the charger so it probably quotes based off of that. As far as ultra power save mode, I don't think it factors that in at all. Just gives us the two separate quotes. Not that I know of anyway. This is an interesting issue to look into. Not sure about much there myself.
[T-Mobile Samsung Galaxy S6] MadLinx:
With minimal usage that could easily add up to 15% per hour. Hopefully a fix is coming soon & this Rock Star phone will be giving us the battery life it seems capable of.

Battery issue

Hi, Am from India - Bangalore and am facing battery drain issues from day 1. It drains about 2-3% per hour in standby mode. Its of no use contacting customer support and service center as well. They replied saying "No issues with phone or battery". I couldn't find VoLTE option in Phone app. I also noticed there's no option of disabling capacitive lights. Am I lacking many features in my phone and still ending up with battery drain issue? Please help.

I've never seen these wakelocks from Google services before.
[T-Mobile Samsung Galaxy S6] grifforama:
And I just went from 93 percent to 86 percent sitting in my pocket for an hour.
[T-Mobile Samsung Galaxy S6] Dr. Fed:
Maybe you can't disable VoLTE because your market doesn't have VoLTE. However, you can download "Galaxy Button Lights" app from the playstore, that will allow you to disable the capacitive lights. No special app permissions either, so that's good.

Also, possibly disabling Always allow scanning ( settings > wifi > more > advanced > uncheck always allow scanning) can help some wakelocks too

Insane. I let mine sit over night and didn't touch it. It never went into deep sleep.
[T-Mobile Samsung Galaxy S6] sublimaze:
Pretty obvious why you are getting crappy battery life. Do you have stock recovery or TWRP? Some phones won't deep sleep after flashing TWRP. If you have TWRP, download Flashify and reflash stock recovery with it. Check this thread for details.

If you have stock recovery, then I recommend reflashing bone stock firmware via Odin, even if you have not rooted. That is the only way to make sure you are starting from a clean slate. This thread links to stock firmware. Reflashing stock firmware is a hassle, but the phone was designed to go into deep sleep and yours obviously isn't. Something has happened that prevents it from deep sleeping, and starting from 100% bone stock is the only way to make sure it is in original state.
[T-Mobile Samsung Galaxy S6] Synyster06Gates:
I am stock with Root via PingPong Root. I have reflashed stock firmware via Odin (three days ago). Since rooting I'm getting more deep sleep, but getting wake locks as my problem now.

Battery issue

Hi All,

Am already seeing posts and threads about rooting device will help in increasing battery life. If so, then I will be more than happy to hear it from you experts.

Please help me as its totally new for me. I google with keyword "root samsung s6 edge SM-G925I" and got links from the same forum but the steps and all the terms sound greek and latin to me. I have following questions:

1. How to root Samsung S6 edge (Model Number: SM-G925I)

2. If I can root it, then how to avoid KNOX trip.

3. Is it true we get increased battery life if we root device. Is this the only reason to root?

I may sound dumb to you guys but please help me so that I may help others in future.

Thanks and Regards,

Richa,
[T-Mobile Samsung Galaxy S6] lukebrantley:
You're not going to magically get better battery life by simply rooting the device. You could possibly get even worse life if your device suffers from the deep sleep issue. With root permissions, you can tweak your phone in various ways to hibernate applications fro draining battery.
