I have a weird issue. My standby screen drain hasn't been too bad after disabling and uninstalling a couple of apps that were sucking battery. But today gSam is showing that my screen has drained about 42% of the battery and I've only had 1 hr 30 min of sot. Does this seem high to you guys??

If you work the numbers out from a full charge if I never put the phone down I would have 3.5 hours sot. Seems really low to me. I did use my phone outside for 30 minutes today with auto brightness on and during that half hour it drained about 20%. It seems like I finally got my standby time to be decent and now the screen is just killing the battery.

Also my phone only drained 21% over 9 hours with the screen off and I streamed play music for an hour this morning. Not bad
[Galaxy S6 General] Fizwiz:
I have the same issues off you after uninstalling APP
[Galaxy S6 General] Ngster:
For some reason, cell standby is completely gone (it was at 20% yesterday, my first cycle). My SOT improved by 1HR. 31% of my battery is being discharged when the screen is off even though the cell standby is gone. I had bad service (only 1-2 bars) from 8-3, which probably is a big factor in the drain. Also, I was wondering if having the phone in my pocket throughout the day could cause drain due to the hotter temperatures.

Oddly enough, most times my phone switches to 3G in my office is after I've had it in my pocket walking around. But it's clear the phone has some attenuation issues anyway, so maybe that's why.
[Galaxy S6 General] ac7822:
What apps did u uninstall?
[Galaxy S6 General] scarchelli:
Hi, i got my sprint s6 from best buy friday. After reading this thread and several others on the net, I've made countless tweaks for better battery life.

- brightness is down and auto

- wifi never scans

- bloatware is disabled/uninstalled

- location history is off and location is set to wifi and tower only no gps

- no apps running causing a problem according to the battery screen

- bt off, nfc off, wifi calling off, never messed with volte so i assume it's on, sync is on for my 3 emails and contacts, nothing else

- i have key vibration off

- i do have 3 tabs in internet opened if that matters

- i know I'm forgetting something lol

I can't post pictures it says until I have 10 posts, but SoT currently is a little more than 4 hours with 17% left. It seems to be going down 1% every 10 minutes or so. I have been leaving it next to me while I sit here with the screen on watching it. I have a galaxy tablet I use at home when I browse the web, however, right now, I am posting from the s6.

So, a little over 4 hours SoT, phone has been on for 13 hours with 3 hours remaining it says. 25% to the screen, 4% voice calls, 4% to cell standby, 4% google play services, 4% android system 3% android os

Look normal?

Thanks.
[Galaxy S6 General] Hemant:
I have been using the below dual sim s6 for last couple of days. Initially the cell standby was very bad and battery didn't last more than 9 hours with almost 4 hours sot. There was an update for my phone which i thought I had installed. After having installed the update which also improved the fingerprint button the battery so fast is holding good. Been switching between wifi and 3g with excellent signal and currently at 83% with almost 45 minutes sot. Location is set to wifi and 3g while location history for google is off. Will see how it goes for the rest of the day. Update seems to have helped but I didn't reset the phone.
[Galaxy S6 General] WhiteHartMart:
25% battery drop overnight again despite phone being in Deep Sleep for pretty much all of it?

I've turned most sync items off but my standby drain per hour isn't far off the in use drain?

Just don't understand why this is so bad - daytime battery was pretty good too yesterday - 16houra standby with 4 hours SOT?
[Galaxy S6 General] jntdroid:
Man I'd take that in a heartbeat. I haven't gotten 4 hours SOT yet... though I might've gotten close today, but it would've been paired with about 8 hours total time off the charger...

Very weird that you'd have that and then 25% drop overnight.
[Galaxy S6 General] mcreego:
Installed ExtreStoLite Rom and my battery faced a big improvement. After 3 hours of intense use I still have 97% of battery. Hope in some good kernel too.

[Galaxy S6 General] oxeneers:
Was having AWFUL battery life. Maybe 10 hours with 1 hour SoT. Then I booted into Safe Mode. Fixed the issue. But, battery life is still not the best. I am on AT&T:
[Galaxy S6 General] tryfound:
Turn off google location reporting and google now if you're not using them, they're sucking your battery life.
[Galaxy S6 General] belloni:
My screen on time doesn't show under battery settings?
[Galaxy S6 General] jntdroid:
what does? could be that your screen on time isn't using as much battery as other items
[Galaxy S6 General] RCJ89:
Got my phone yesterday morning but I was at work so started setting it up around 9.30pm with battery at 59%. I set up finger prints, my ring tones, I had wifi on from then until 1am, screen brightness on auto, made on 1 minute phone call, sent various amounts of texts, sent various whats app messages, downloaded some apps and games, uploaded some music which was very fast indeed, played some music, played around with the phone for a bit, SOT was 2hour 21mins 22 secs before I went to bed at 2am with the battery on 20%. I woke up this morning at 8am with 19% battery remaining, so 1% drain in 6 hours.
[Galaxy S6 General] Japultra:
What do you have your screen brightness set to? What mobile network are you on and how strong is your signal?
[Galaxy S6 General] RCJ89:
Screen brightness was in auto, i had full reception bars the whole time and I am on vodafone uk.
[Galaxy S6 General] DeathmonkeyGTX:
Necropost, but we aren't the core audience. The core audience is the millions of regular people that buy them. We nerds are a minority in the market.
[Galaxy S6 General] beef356:
Not too bad i dont think.
[Galaxy S6 General] das boot:
I would say that is better than average
[Galaxy S6 General] vegetaleb:
How's the battery life for non-branded (meaning no Tmobile,AT&T,Orange...) version of S6?

And if possible compared to other phones like S5 and M7, M8?
[Galaxy S6 General] tmac31:
Similar with m7. Worse than s5 and m8.
[Galaxy S6 General] CLARiiON:
Non-US versions seemed to be getting better batterylife. That's what I felt from numbers given so far.
[Galaxy S6 General] vegetaleb:
M7 was good so the S6 is good, of course it will never be as good as z3 but surely better than M9, I heard it's pitiful
[Galaxy S6 General] johanbiff:
Having good batterylife..3rd charge with some gaming, filming, foto and with brightness at 50%. .4G and wifi always on..pic taken With 15% left.. 920F model...I have not managed to get bellow 5h screen on time, dosen`t matter what I do..
[Galaxy S6 General] WhiteHartMart:
5 days in and daytime battery life improving - today on target for 20+ hours standby and 4 SOT - if only I could work out my awful overnight drain - 25% and 30% last 2 nights?
[Galaxy S6 General] Brava27:
Awful awful!

3.3 discharge while I sleep! Why?
[Galaxy S6 General] microserfs:
Okay so I left the phone to its own devices in my room while I did some other things after waking up, and for some reason I lost 10% battery in an hour and a half. Wifi was on, so obviously I had some push notifications coming through occasionally, which might have woke the phone from sleep quite a few times, but I still don't see why theres such a big drop in battery? GSAM is telling me I've lost 7.6% an hr (used 13% in 1hr43 mins) but only used 19 mins of screen on time! Wifi active 13% (could this be the issue?) but app usage is 43% with Android system right at the top... any idea what Android System would be using the battery for when I'm not using the phone?!

This is a huge hassle for me as I'm quite a medium-heavy user of the phone and I got this instead of the iPhone 6 in the hope I'd have more success with battery as my iPhone 5S wasn't doing so grand.

Any advice on what I can do? I've turned wifi off for the moment (which is frustrating as I obv would prefer to keep it running), location is off, I don't have an option for VoLTE to turn off as I'm from the UK on Three, and I've got auto brightness on to minimise screen brightness in the daytime.
[Galaxy S6 General] elbos2k:
Do a factory reset. Could solve the problem. Also, give it a few days for the phone to settle. A few users are reporting better battery after a few cycles and a few days of use...
[Galaxy S6 General] microserfs:
Thanks! I've had it since Friday last week so was hoping it would have settled by now. I'll give it an extra few days to see how it goes. Is there a way to back up data/apps on this before factory reset? I switched from iOS just recently so I'm not sure what the backup process is usually for Android.
[Galaxy S6 General] WhiteHartMart:
I'm 3 also and my battery life is much better now although it seems to drain must as much when in standby as when I use it [emoji14]

Wonder if its related to the 3 firmware!?
[Galaxy S6 General] microserfs:
That'd suck real bad. I'm hoping that it's something that can be fixed with an update or something! I was convinced it might be Lollipop or at least something on the phone that is affecting the battery, but at this point, anything goes. Have turned off wifi for the time being, which is frustrating as I'm not getting the full use out of the phone I want.
[Galaxy S6 General] tiptop10:
I had a similar issue the 1st and 2nd cycle, on my 3rd now and I dont have the issue anymore. I disabled a few apps I wern't using so I doubt that did it, but I did put my phone into safemode for half an hour last night, charged it up to 100% and unplugged it before I slept, only lost about 3% the time I slept (for about 7 hours). And for the the rest of the day Its been WAY better than the previous days, it actually sleeps when i turn the screen off, I'm on my way to getting over 5 hours SOT with 20h+ usage time. And for what it's worth I've got the UK version bought from samsung, I used wifi the whole time, tomorrow I might try 4g.
[Galaxy S6 General] elbos2k:
I just back up contacts and calendar data in Google. Can you check your Advance WiFi settings? Make sure it looks like this...
[Galaxy S6 General] subben2003:
I read that if you have said yes to download apps and settiings from Samsung in the first start up the phone would drain more rapid

I didn't use that obtion and have a very good battery statt

Unplugged at 5.20 this morning and have 75% left now at 7.47 evening

screen on for 1.5 hour

love my new phone :)
[Galaxy S6 General] :
How do you get there? I don't have the advance options under more..
[Galaxy S6 General] microserfs:
I've charged the phone like 5 times since I got it, admittedly Iv'e never drained it to 1% (I think about 15% before I start to charge again) so I would have thought it would have been on its 6th or so cycle by now, which is why I was hoping for improvement. How do you put the phone into safemode? I guess I could try this method and see if it helps anything.

How do you get to the advanced wifi settings? It doesn't look like I can find it on my phone for some reason, I might just be looking in the wrong place though :confused:

Wow, that's pretty awesome. Yeah, I think I did agree to the settings and apps and stuff, but wasn't sure that would affect it. Should I turn that stuff off?

---------- Post added at 07:13 PM ---------- Previous post was at 07:06 PM ----------

Could the wifi constantly dropping be an issue too btw? For some reason, my phone always seems to connect and reconnect to the router at home. Not sure if its a router issue or if the phone is having problems with it somehow. Internet works fine on my laptop and so forth, but the phone is struggling with holding a solid connection (or is just telling me its connecting all the time)
[Galaxy S6 General] jacindc:
I used the Google "bump your old phone to transfer the settings" when setting up the S6, and I've wondered if that is part of the problem with the battery. I hate the notion of doing a factory reset and having to start over, but it may come to that. I'm going to delete all unnecessary apps that were installed that way, though.
[Galaxy S6 General] subben2003:
Do a total reset and start up saying no to any transfer or anything else like that
[Galaxy S6 General] elbos2k:
Settings-Connections-Wifi-More-The More option should appear on the top right...
[Galaxy S6 General] tiptop10:
Yeah I've discharged my phone completely every cycle so far, the phone actually hangs on the last 1% for considerably longer than the other %'s. So I assume the battery/OS is a little out of sync. It's performance has gotten better overall as well and it might be due to the whole 100 - 0 discharge as well. and to go into safe mode you have to switch off the phone and then power it back o and hold the volume down button when the samsung logo appears.
[Galaxy S6 General] :
Not on my version
[Galaxy S6 General] elbos2k:
What options come out when you select that "Always scanning"?
[Galaxy S6 General] :
Its always scanning regardless which one I choose.
[Galaxy S6 General] elbos2k:
What about the "smart network switch" option? [MENTION=3293431]recklesslife85[/MENTION]
[Galaxy S6 General] elbos2k:
Also check you sync settings for each app. Go to Settings-Personal-Accounts. Uncheck everything from within the apps in this setting. For example:
[Galaxy S6 General] microserfs:
Okay thanks. I guess I'll give the complete discharge a try as well as safe mode if it comes to it. Hopefully this will start improving things a little. bit worried as it's already nearly been a week and I haven't had any improvement.

Nor on mine, is your phone a UK phone?
[Galaxy S6 General] :
Done, hopwfully this fixes it for me
[Galaxy S6 General] elbos2k:
Cool. Did you check the "smart network switch"?
[Galaxy S6 General] :
Yes that's been turned off. I've only left gmail on autosync, everything else is switched off to manual.
[Galaxy S6 General] elbos2k:
Awesome, good luck!
[Galaxy S6 General] Japultra:
Discharging the battery completely is not good for the battery. http://www.phonearena.com/news/How-...phones-li-ion-battery-the-correct-way_id67159
[Galaxy S6 General] microserfs:
Yeah I figured it might not be. Not sure what else I can do other than factory reset the whole phone and see how it goes. Have made sure to stop getting notifications from Facebook which seems alright for the moment, but I can't seem to find the option to stop auto sync?

Never mind found it. Will see if that might help a little.
[Galaxy S6 General] supposedmonster:
Hey I just wanted to echo what many have said about a factory reset solving the battery problem.

I was stock unrooted (I wanted to wait a month or two in case there were any OTAs), and had taken the first OTA. About a week of use. This morning I had over 10% battery drain in under an hour with zero usage, and decided I had it. Cell standby and Android system had routinely been in a close tie for battery usage, followed by screen at a distant third. During short activities like browsing Reddit for 15 minutes I could watch the battery drop a few percent.

After the factory reset, Android system and screen are at a close tie with cell standby at a distant third. I browsed the net all lunch today with barely any drop in battery. Not very scientific, but the difference was drastic enough to report empirically.

Also, turning VoLTE, wifi calling, and network/wifi location services off did not have a discernible impact prior to the factory reset for me. I have them on now and it seems to be fine. Not that turning those things off couldn't help battery life, but it hasn't made an impact on the massive drain that's been the problem.
[Galaxy S6 General] crazymook:
Barely used the phone at all today. Sat on wifi at work and now I'm home back on wifi. This is such garbage. I'm on Sprint, located in IL.

I dont know if the phone isnt playing nice with my wifi at home and thats causing a fast drain...I only burned off 10% while at work which I thought was great. But once I left, the drain came back. You can see where it starts to tank around 3:45.
[Galaxy S6 General] oxeneers:
There's something wrong with the WiFi module. Leaving the phone on WiFi and idling absolutely destroys the battery. I don't get it.
[Galaxy S6 General] crazymook:
I just factory reset to be absolutely sure.
[Galaxy S6 General] :
I did a factory reset and turned off all sync options but left gmail on and it seems to have done the trick for me so far.
[Galaxy S6 General] tiptop10:
When I first got the phone it took me about 1 & half hour to set up the way I want (downloads , updates, configuring , etc) so factory reseting mine would be the death of me, luckily my battery life is more or less great now (no annoying idle drains here anymore :) )
[Galaxy S6 General] elbos2k:
Read the last few pages. I've posted some tips on how to improve battery life...
[Galaxy S6 General] jacindc:
I found that Smart Network Switch was still on--which aggravates me because I was sure it wasn't--so I will now spend a day or so hoping that that is the magic cure. (Have already turned off lots of the other things suggested in this thread, though not to the point of crippling my new toy.)
[Galaxy S6 General] dlscott1111:
Can you share some things you are doing that you think are helping you get such good battery life? Thanks in advance!
[Galaxy S6 General] Gboss01:
I did nothing more than I read up on here.

Turned off VoLTE calling and disabled some bloat.

Turned off Location and Bluetooth when not in use.

I access FB via the browser as I read the FB app can cause battery drain.

I leave sync on though as I have 2 email accounts configured that I need sync'd.

I have not rooted my phone yet, once I do I'll remove the bloat and not just disable it.
[Galaxy S6 General] crazymook:
Factory reset MIGHT have helped. Looks promising. Crossing fingers.
[Galaxy S6 General] rigssanchez:
One Week in and here was last nights stats.

24hours with 4 hr Sot with 10% left

With

Volte off, WiFi off, WiFi calling off, always scanning off.

GPS only location.

Auto brightness (centered)

Full syncing.

Plus very light Bluetooth use and no phone calls.

Still using Google Now launcher.
[Galaxy S6 General] Speran49:
On Verizon Galaxy S6.

I made sure to factory reset once and I disabled basically all the bloat they would let me. Verizon really put a lot of crap on hear that will run in the background if you don't stop it.

There is an obvious bug in the built in battery reporting. I have cell standby at the top but if I use GSam I seem to be given the correct measurements and cell standby is very low.

Nothing syncs except my email every few hours and weather every 12.

I also keep power saving on (hate capacitive lights). Few google service still run that annoy me but they seem to have minimal impact.

This run:

-Only charged to 94% add extra 30 mins or so SOT to mine for 100% score

-Used 4g and 3g in building with mediocre signal during day.

-Had WiFi on at night and while sleeping.

-Used Power saving

See images for rest of stats. I find I am extremely happy with battery life. This could go for days with minimal usage. The fast charging also makes it very easy to recharge. Im trying to keep battery between 30% and 85% to increase longevity. Easier than I thought it would be :)
[Galaxy S6 General] crazymook:
10 minute awake time?? How the hell...I mean how is that even possible with a full 24 hours of use?
[Galaxy S6 General] Speran49:
Like I said. Nothing really syncs. I keep it all manual for the most part. I don't have any games or Facebook crap running so the phone sleeps when I turn the screen off. As it should imo. My battery drain while off is less than 1% an hour.
[Galaxy S6 General] crazymook:
Thats insane.
[Galaxy S6 General] Gboss01:
:d
[Galaxy S6 General] WhiteHartMart:
Totally agree. Last 2 nights on WiFi - 30% and 25% in a 7 hour or so sleep - last night turned Wi-Fi off and battery only drained 3%!
[Galaxy S6 General] mcreego:
Installed XtreStoLite Rom and now I'm facing my second days without charging the battery. Give it a try, it's insane the improvement.
[Galaxy S6 General] belloni:
After rooting went so well, I'm now getting a huge android system battery drain. Looks like I'll have to factory reset ffs.
[Galaxy S6 General] apsis:
I just recognised that even with turn off WiFi in standby while not being charged, gsam tells me that WiFi is still active all that time until I turn it off manually. I looked into it and recognised that WiFi direct was running and sending all the time, I killed it and now WiFi goes to sleep. I also recognised that within the quick connect settings, always visible was on by default.

Anyone else see this?
[Galaxy S6 General] iMask:
Why complain about overnight battery loss? Is it that hard to turn off your phone while you sleep?
[Galaxy S6 General] jntdroid:
If it's your alarm clock, yes. :)

I think the point has to do more with idle battery loss, rather than just overnight loss exclusively.
[Galaxy S6 General] tiptop10:
overnight battery loss is indicative of phone efficiency. if it drops more than 5% overnight then something is wrong.
[Galaxy S6 General] microserfs:
Okay so by last night I think the most I got was 4 hours of sot, but that was with turning wifi off for a lot of the time. I still think something is keeping my phone from entering deep sleep properly. I've installed wakelock detector to give it a try and see what apps are running the most while the phone is idling. This is probably my last resort before I have to do a factory reset. I'd rather not since I've installed so much since having the phone, but with only 6 days left in the return policy it looks like it might be my only option. Facebook has stopped syncing for the most part. I think I might try uninstalling the app fully to see if that improves things though.
[Galaxy S6 General] le_lutin:
You think you should turn your phone off at night to save battery, is that it?

Not so sure that'd work for most people who might need to be contactable in case of emergency
[Galaxy S6 General] mcreego:
Where you got this statistic? I think is wrong. Do You mean 5% loss with airplane mode on or with every connections turned on?
[Galaxy S6 General] tiptop10:
not gonna lie, I don't have statistics to back it up, just experience. Most recent phones are capable of dropping no more than 3% overnight with everything still connected (My S6 did this the other night).
[Galaxy S6 General] apsis:
Of course it's capable of archiving this small drain with 3g/4g/WiFi enabled.

My stats from last night.

I leave my phone running at night for emergency cases. I also use it as an alarm.

Standby drain is a important fact for me for the all over battery life. If standby drain is already high, battery life over the whole day can't be any good.
[Galaxy S6 General] elbos2k:
Did you check the advance wifi settings?
[Galaxy S6 General] iMask:
Or just turn off WiFi and enable ultra power saving mode. If, after that, you get more than 3% drain, something is wrong with the battery, or you have too many wakelocks.

I'm going to try doing this tonight.
[Galaxy S6 General] RSC10:
I also had 10-12% drain overnight. A factory reset fixed the issue for me. Last night took the phone off charger at 10 pm at 100%. Got up at 6am still at 100%. Happy.
[Galaxy S6 General] jntdroid:
Wow. That would be awesome for any phone. You must not have much going on in the background?
[Galaxy S6 General] RSC10:
Just one gmail account syncing. I also closed all open apps.

That's the same routine I had been doing while getting the 10-12% overnight drain, however.
