How much time do you people still need to be able to make the difference between a device and an OS? Comparing devices on different OS is as useless as it gets especially when we ALL KNOW why lollipop sucks at battery life.

I also have a Z3C with its crazy battery life (2 days of usage and 7-8h of SOT or close 9h on Wi-Fi with my usage pattern of course). As soon as I switched to lollipop the battery life took a nose dive, exhibiting the exact same problems like my even older Nexus 4 (radio drain, play services drain). Downgraded to KitKat - great battery life again. We are talking about the same device!

From my observations, the battery life on the s6 is far from bad, even with its tiny battery size. I'm getting between 7 and 8h SOT on Wi-Fi so all the problems come from the revolting bugs in lollipop and which are completely ignored by Google.

Battery life on the s6 is horrible. It has the worse battery life for a phone that I have ever owned. Avg 6% battery drain over night, days when I'm on WiFi 100% I barely can squeeze out 4 hours with just reddit and Tapatalk. If I drive 20m with Bluetooth and Spotify my battery will tank around 20%. I can keep on going and all this is on stock OS with as many battery draining process disabled.

Please explain 7h to 8h SOT in the S6 we want to know.

Battery problem

Hi

I didnt know in which topic to put this message but I hope someone can answer me.

Im having problem with my SGS 6, whenever I go to see battery usage in settings all I can see is screen usage, few Android processes ( Android operating system, device idle, wi-fi, cell standby, mediaserver and Android OS processes ) and only 2-3 apps that I installed.

That would be fine if I was only using that apps but when I check whats using battery with other 3rd party programs they showing everything correctly. They showing google play services, twitter, Samsung push service, messanger, facebook app, viber and everything else that should been shown when I want to see whats using my battery and what percentage of battery is used.

I dont have time to do complete restore so I´d be greatful if someone knows whats happening and if someone else have this problem. Is it because notifications are turned off for 90% of my apps but I think that should not affect that.

Thanks! :)
[Galaxy S6 General] Nplus1:
- disabled / uninstalled most of the bloat (Google + Samsung)

- installed Lux and configured brightness profiles that I consider good enough (8% dark room, 15% faint reading light, 25%-35% daylight indoors, etc)

- disabled motion gestures (not using any of them)

- disabled all possible Google settings on the phone, including location reporting

- high precision location always on (!)

- using Nova launcher (but most certainly no impact)

- connected to Wi-Fi router at less than 10m away on 5Ghz

- using the phone for browsing, chat, social networks, taking photos or casual gaming

Just for info, here is GSam Battery Monitor's average estimation based on a mixed usage Wi-Fi / 4G+ with acceptable coverage (and obviously under the effect of the radio drain bug): 6h20 SOT. Less 4G -> less radio drain -> more battery

You are kidding :D

You got 6 hours sot but you have 76% left? :D

Thanks for trolling...
[Galaxy S6 General] Nplus1:
I have no idea what scenario GSam uses to estimate the max remaining battery life. Probably screen always on with an average usage pattern. Even so, 1h38m already used + 3h6m for max usage is still not bad. This is in the context where 25% is used by the stupid Android processes keeping a data connection active at full power all the time.

If you're not able to read a screenshot that's not my problem.

I'm sorry.

I misread you screenshot.

Shame on me.
[Galaxy S6 General] cavags5:
For all your settings im pretty much close what you have, and make a lot of tests, and with only with max few months ago with first 5.1.1, 6.20h sot with the recent 5.1.1 6h sot, only with 4G 4 to 4.3h sot, and for you make 8h even only with wifi and 10% brightness or less i would say its pretty impossible.

And you say location always on.

Do it and post here.
[Galaxy S6 General] Lucoso46:
I did a lot of these things, but no more of 5 hours of SOT. :(
[Galaxy S6 General] Nplus1:
I will post screenshots as soon as I have a full charge cycle on Wi-Fi only, but that's why I posted the previous screenshot where GSam gives an estimation of 6h20m with about 50:50 ratio between Wi-Fi and 4G+.

Contrary to popular belief, keeping the location always on seems to have no (or very little) impact on battery life as long as you don't have rogue apps or strange wakelocks. When Play Services work the way they should, location wakelocks of 15-30 min/day should be expected, which is perfectly acceptable.

My battery life is good enough for me. G920IxxxDOL5. No root. Use greenify, package disabler pro, always optimise apps, apex launcher, advanced task manager to kill some tasks from time to time like gmail, YouTube, GPS off, Google apps and now disabled. Screen colour set to Amoled Photo! Mostly 2G network, 4G very rarely, Wi-Fi 80% time on, YouTube a lot, camera about 1 minute use, tap tap dash on occasion and browsing a lot on Samsung Internet and Opera Mini. But I give all credit to using only 3% brightness using an adjuster like Brightness level app by curvefish which seems to be like 6% brightness on the S6. Outdoors or when I need it, automatic brightness. But I find 3% to be bright enough for me and my favourite theme Grace Ui!

When 4G always on and playing 'heavy' games, about 4- 4.5 sot, but that's very rarely!

Sorry me english :)
[Galaxy S6 General] Fullmetal Jun:
Please no need to apologise for your English.

It's in Samsung theme store. You can try using a vpn app to change your country to USA. Then you'll see paid themes which are not supported in all countries. Try a vpn app like TunnelBear from play store. I think you'll also need to use a different account where your address is in USA. Try searching in the Themes thread. I don't really know if it'll work. The themer is Hiten Soni, HS.
[Galaxy S6 General] Biggenz:
I thought my SOT was pretty poor until I saw how long I would get if I flattened the battery completely. Seems it's not so bad after all. 6h SOT with 4G, wifi, location etc. switched on.

My battery has just increased from 2% to 4% ... It's happened to you?
[Galaxy S6 General] nvrmndryo:
Almost 9% battery drain in standby mode in night. It's too Much right?

I have disabled many useless apps, I use greenify, power saving is on. I usually get 4hrs of sot. So please tell me what I am doing wrong? My friend also has s6 n he says in standby mode in night he loses max 1%.
[Galaxy S6 General] cavags5:
You are rooted or stock,?

If you are sleeping you don't need the wifi on.

Just use the package disabler, and at night airplane mode..

And wipe cache partition once a while, and reboot every day.
[Galaxy S6 General] nvrmndryo:
I am on stock rom. I can disable wifi but can't put phone to Airplane mode. I tried package disabler but it didn't work last time. I will check again. But which packages should I disable?
[Galaxy S6 General] cavags5:
Im testing a old app but improved seems to be good with Wi-Fi.

And you must disable what you dont need or use.

I wanted to make a video but dont have the time.
[Galaxy S6 General] Dexter_prog:
there's no point in disabling wifi if you are sleeping. I get 1%/h drain overnight.
[Galaxy S6 General] theclaytons:
Surely 1%/hour overnight is too much?
[Galaxy S6 General] Lucoso46:
What does this mean?

1 percent every hour?

If you lost 1 percent every hours yeah, deep sleep problem.

Check your wakelocks :)
[Galaxy S6 General] Nplus1:
Still didn't get to use the phone 100% on Wi-Fi but battery life seems to be decreasing with the same usage pattern. Not only this, but I'm noticing that the reported SOT is different between system battery usage and GSam. Sometimes system usage shows less than GSam, sometimes more.

This lollipop sure is a messed up OS.

Hi there guys!!!

Well, here's my own screenshot showing my Samsung's battery life. It's not that I'm complaining , as I've recently installed XtresoLite ROM and it works like a charm. But here's something that annoys me. Why are Google Services taking the most of my battery life? Is there anything I can do about that?

[IMG="ey!"]http://i.imgur.com/WviP8m0.png[/IMG]
[Galaxy S6 General] Dexter_prog:
No, it's perfectly normal, it's barely the same I lose during daytime

It's pretty clear: "1%/h" = 1 % per hour, and it's not a wakelock or a deep sleep problem. There's no way a phone can lose 0%/h if it is running. I don't disable things when I go to bed like most of you people do. When I got to bed my phone is as functional as during daytime (wifi on 24/7, sync on, etc)

Currently: 1 d 12 h with 37 % remaining.
[Galaxy S6 General] theclaytons:
If i put phone into airplane mode i lose 0% overnight....
[Galaxy S6 General] Dexter_prog:
Good for you, I don't put it in airplane mode unless I'm in an airplane or a similar place such as a submarine or a bunker.
[Galaxy S6 General] theclaytons:
Yes, when i am in a bunker i put mine into bunker mode....i was only testing this to see if i could isolate the cause, i do not bother in airplane mode even when on an airplane...
[Galaxy S6 General] Lucoso46:
Okey guys! I saw that a lot of people saw that Marshmallow battery drains are solved.

Tomorrow i Will test: i will get up at 6.00 a.m and from 6.45 to 7.30 i will use my phone as a MP3.

Than from 8 am to 2 pm in idle or little use.

From 3 pm to 12 pm social usage. We will see if S6 can stay alive tomorrow :)
[Galaxy S6 General] Dexter_prog:
Alright, should've said that in the first place. Frankly, I don't see 1 % overnight with everything as functional as during daytime as a problem, perhaps you guys are pushing it too far.

On a side note, I noted that Adguard adds about another 0.5-1% extra of drain if activated.
[Galaxy S6 General] Error404html:
I just like the quick charging.. but the battery is not big enough to works a full day (using it much)
[Galaxy S6 General] jocaboss:
Here are the battery pictures of my first day with 6.0.1. A lot of use to install all my apps again and reconfiguring all.
[Galaxy S6 General] zhangmaster12:
ATT GS6 user here. I get about 9 hours total battery life and just over 2 hours screen on time.

Now, I'm not the most battery frugal user, but I use all these features constantly throughout the day. Most of the day is in 4G as I don't have wifi 90% of the time. I don't play any games and only do a little Stitcher/YouTube/Twitch streaming throughout the day.

Most used apps:

- Google Now (without voice detection ). I use the cards a lot.

- Facebook

- Location

- Snapchat

- Myfitnesspal

- Twitter

- Instagram

- ParcelTrack

- Google Sync (wifi only for pictures)

- Google Apps (mostly Play Music, Maps, Gmail)

- Chrome

- Google Device Manager (for security reasons)

I've used Package Disabler to disable all bloatware. I usually don't clear background apps from memory, should I be doing that? Also will clearing cache and rebooting every couple days help battery life? I know I won't get anything spectacular, but 2+ full charges per day gets annoying. Thanks in advance!

So the battery life on MM is the only thing I'm not so sure about. Looks like I lose almost a third of my battery to background processes. Hope it's only a post flashing thing though. Mobile data/wifi always on, location, sync off.
[Galaxy S6 General] cavags5:
Try it with apps Otimization off .

And lets us know.

The end of the dar i post here mine.
[Galaxy S6 General] cavags5:
Here it is all day 4G only at lunch a little with wifi.

Not bad but not as lolipop.
[Galaxy S6 General] Lucoso46:
Bro i will try with optimizations off
[Galaxy S6 General] cavags5:
I had it off.

Now im disabled everything and change the stock clock.

Tomorrow i will change to nova launcher.

And a couple of days i bought again a note 4 for a good price , i miss big screen.

And the battery don't last much longer.

I had a s7 and s7 edge in my had and the edge feels really good in hand.

I know its a demo version but its pretty nice,but s6 with M s7 is not much faster.

Lets wait for the reviews.
[Galaxy S6 General] Lucoso46:
50% 1.30 with hard use. Started with 100% install a lot of apps and surfing the net.

Also there is a reviewer in Italy who is testing the battery of S7 edge. He said that it is IMPRESSIVE.

He used a lot the S7 and he arrived at 10.20 p.m. at 11% with 5 hours.

I saw his usage and his very hard.

A lot of gmail accounts, Telegram, WhatsApp, Voice Calls and web browsing. I think if i have a S7 with my usage the battery can reach 6 hours of SOT...
[Galaxy S6 General] omeryounos:
Even on MM, the standby battery drain is similar to LP i.e. About 1% per hour at night. In comparison my IPhone 6 and 6 plus with same Network and Apps loose only 2 - 3% in 8 hours stand by. That is less than half actually. I thought with doze in MM we will see big reduction in stand by drain for GS6. Seems like I was wrong, doze doesn't seem to have an effect.
[Galaxy S6 General] cavags5:
No it doesn't.
[Galaxy S6 General] cionn:
Yea but the iPhones battery life starts dropping after like 6-8 months of usage, and also the battery drops even harder if you watch videos or do stuff on the internet.

I have been using iPhones since the 3G model, every time the same crappy battery (not in mAh but in the duration) life..

Imho I'm really satisfied with the battery life on MM. I get around 2,3-3h SoT, arrive home with 20% which is still enough to endure the time before going to bed.

The only thing I am worried about is that there are too many apps still running in the background (e.g. for screen usage it says 40% but there are a ton of apps that use between 1-3%)
[Galaxy S6 General] osiris355:
So the verdict is doze has no affect on the s6 terrible standby battery? That's a huge bummer. This makes me think the drain is due to the radio being separate the the CPU or something. My 5x hardly drops when not in use.
[Galaxy S6 General] svinyard:

[Galaxy S6 General] johanbiff:
Xef 6.0.1* This is with WiFi on and no apps closed under sleep time. Doze on auto. I lost 2% over night this was NOT possible on Lollipop for me, I lost almost 15% over night! I also get 5h + SOT with a 1 year old battery.. for me MM is better by a mile!
[Galaxy S6 General] Falster:
Don´t judge on the battery so fast, let it settle for a while. My first day with MM was quite good, running ~ 16h in total with 3h 45min SOT, battery went down from 100% to 36%.
[Galaxy S6 General] omeryounos:
Have you disabled any built in apps / services or it is as per default setup. The standby drain is impressive and I wish it would be true for me as well.
[Galaxy S6 General] nvrmndryo:
I left my s6 for charging last night and forgot to plug out, so it was on charging for around 7 hours. Does it affect on my battery now?
[Galaxy S6 General] johanbiff:
not using any debloat app just deactivated the apps I don`t use
[Galaxy S6 General] AB__CD:
Nope. Modern batteries are designed to automatically cut off power at 100%, so the phone is refusing the power from the charger, and will only occassionally reopen when it's at 99 to re-top up to 100. It will NOT damage your battery the slightest, though it's still a good idea to plug out to save on electricity.

---------- Post added at 12:13 PM ---------- Previous post was at 12:08 PM ----------

Try wiping your phone after major updates. LG G2 battery was pretty rubbish after Lollipop, with 2h SOT max, and constantly lagging and running hot due to memory management issues presumably due to flawed installation or data moving process on LG's part, but is awesome after wipe. Yesterday I managed 16h total, with 1h SOT, and had 75% leftover!

So yeah, Android will never be as "no frills" or "no need for micromanagement" as iPhone in the near future, but Android does reward you more if you have the time and effort.
[Galaxy S6 General] WolfsFang:
Really don't understand why I'm getting good battery life all of a sudden when I haven't changed anything. But just look at the radio drain, imagine if it had no radio bug.

Power saving mode on.

100% on wifi.

20% manual brightness.
[Galaxy S6 General] Lucoso46:
A lot of browsing, WhatsApp, Facebook with 4G+ . I Think that is good in Italy.. also first day of use with Marshmallow!
[Galaxy S6 General] cavags5:
Well my friends here is my post from 2 day with M and with my settings modified.

My review is i think they stabilise it very well.

Its running good like lolipop.

I have to make only one more test with power saving on.

Today in the morning 30min sot with wifi , then leave home until now always on 4G, standby its good, if i don't touch it maybe 1% half an hour , but its always messenger notifications.

Other thing i tested, you can put optimization always off because dont work on M.

No matter what you do some apps are always running.

But i think is good .

All the apps now are consuming a lot less RAM. I have to make a video with my settings but don't have the time for now.

At the weekend will test only wifi.

And i don't forget nova launcher and NO stock weather.

With MM not bad I think
[Galaxy S6 General] botanicfts:
On Stock MM. Brightness auto, slider on 20%. Several long telephone conversations ( every about 30 minutes), much whatsapp, messenger, instagram, snapchat, facebook etc. also typical daily use. All day on the mobile internet (always LTE/4G). I say this because it makes a big difference, as opposed to the whole day on WiFi in home. I think 4h SOT (yes, i know, there are only 3 hours, but i could quietly reach up to 4 hours) is a very good result, especially if we are talking about using your phone outside for about 10 hours use with always mobile internet on. All day on a single charge, it satisfies me.

So, if we compare the battery life between the marshmallow and lollipop... I leave the answer to you.
[Galaxy S6 General] cavags5:
