Nougat VS. PL6/PL2 battery life - Sprint Samsung Galaxy S7 Questions & Answers

i cleaned installed nougat, and the battery life is just ****. nothing like when i was on PL6. i want to know what your battery has been like for both or either OS version. I hope the next update fixes battery life, or i'll just have to go back to PL6 or PL2.

i got back to pl2 U firmware

After a week, rebooted and been okay on battery as good as old one, I have been looking at apps that use up battery power and I tune them up from not running so much wasting power. Nougat is so far easy to use, more options into details, so far it lasts me to about 2-3 hours screen time with pixel launcher, I also used samsung disabler app to turn off bunch of apps and use hangouts as primary SMS, MMS app. So far, it's a good build, I'm sure there will be few more tweaks released to soften battery consumption.

[Discussion]Android 6.0 Doze Mode

This thread is actually meant for discussion about how doze works, whether it works (debateable), setup and everything.
My suspicions is that doze does not work for custom ROM or any Android OS that is not certified by Google. My reasoning behind this is quite simple.
What I did:
1. On various 5.x ROM, if I were to leave my phone overnight and even with wakelocks, I have never lost more than 3% of battery.
2. On kitkat, the situation is similar and I have never also lost more than 3% overnight.
3. On multiple MarshMallow ROM, leaving the phone overnight drains more than 4%.
To make things clear, on Kitkat and Lollipop, my phone was left idling for more than 8hrs. But on MarshMallow, I have only left the phone for 6hrs and I lost more than what is on Kitkat and Lollipop giving me the idea that doze does not work. I have checked the battery graph in settings and it shows that there's barely any wakeups for the device but battery was dropping quite noticeably.
I have attached a image of my stats today in school. If you take a look closely, there's a certain period of time where under the "Awake" section, there's no wakeups, my battery was still dropping and doze was not even kicking in at all. And I can assure you, that was over a period of 2hrs as I did not touch my phone during class time.
For those that are interested in configuring Doze to test whether my words are accurate or not, I've have the necessary apps linked below.

For those that are interested to chip in the discussion, feel free to do so. Uploads screenshots of your battery graph to backup your words for better and more fruitful discussions to come. This is not about battery life related like SOT, standby etc. It's mainly for discussion about doze whether its working for you or not. Or if doze is actually working and not a gimmick. I don't know.

As far as my experience goes with MM and KK ROMs,
I completely agree what you told about battery life in KK.
However, that was KK! Battery life in MM is much better than that in LP. I agree that KK was much optimized. But forget about it for now as ALL the Custom ROMs based on MM are still in ALPHA stage.
It means that you can expect better battery life than current scenarios once CM provides STABLE builds
Regarding Doze Mode, yes it works for me
These are my today's battery life stats https://www.imgur.com/a/PC2V4
good call man,
I have notice that too. I tried all thats MM roms alpha in Xda. even in oficial Cyanogen nightly the battery life is something like good and not awesome like promised.
until now the best battery life in all Roms between KK , LP and MM is in Paranoid Android Stable Rom.
PS.: I have use Greenify in all that ****.

Hi there! I would like to know if u r using V4A FX on ur phone? I have seen people complaining about the battery life using the same ROM that u r using.
As for what i have noticed that earlier when there was no workaround for the r/w system remount error there was no way of making V4A work which is why i was only using the default audio fx and at that time i was getting almost the same battery stats as ur's sir. I just believe that V4A could be the reason of the drain as while installing it warns us firsthand about the battery drain it can cause.
I know that what i am saying is not the case with either kitkat or lollipop. This could be because V4A hasn't been exactly made for Marshmallow yet.
Using doze settings editor to have doze kick in instantaneous whether in motion or not I have noticed I no longer receive emails through gmail if my screen is off. If I'm using my phone I'll get a notification but if the screen is off I won't get a notification until I open the app.
Also my battery life is better than ever. I'm not getting ridiculous sot or anything but standby is great. Off the charger at 6am and back on around 12am I'm left with 20 -30% left on average where as on lp it'd be dead by 8pm. Averaging 5.5 sot. Using official CM13. Just switched to Sultans CM13 and battery already seems much better.

I've tried multiple MM ROM - from AOSParadox -> BrokenOS -> Omni ROM -> SlimSaber (Omni-based) -> CM13 CAF/ CM13 Nightlies and with or without configuring doze using NapTime or Doze Settings Editor, I can easily get past 2 days of standby with 6.5hrs of SOT which in comparison to Lollipop is much better overall.
But no matter I set doze to kick in 5mins, 10mins, 15mins or 30mins, I don't see much doze really doing wonders during deep sleep. And to make my test consistent, I had left the phone in airplane mode over 2hrs and my standby loss throughout that 2hrs was 2% which compared to Lollipop is quite bad as placing the phone in airplane mode can result in 0.3-0.5% battery loss in 2hrs.

I kinda am getting the same if not similar impressions. I've tried most of the super alpha builds of most 6.0 Roms until Sultan Started his CAF CM13 builds which is what I've stuck with since then.
Battery life seems to be Marginally better than LP, I haven't used any KK roms on my phone so I don't really have a baseline to go off of for getting ridiculous battery life. I am however getting an average of about a solid day and a half on a single charge. 5 hours SOT is the most ive been able to achieve. Nothing to complain or gripe about, I can get a full day of heavy usage without worrying about plugging in to make it to the end of the day so I'm happy.
The one thing I CAN say however, is Marshmallow definitely feels so much more fluid and snappier than LP, and RAM management seems to be much better. I have apps still in memory from like the previous day, and when I open my app, its right where I left off, versus reloading the app. So I call that a win :good:

Betterbatterystats isn't reporting many wakelocks at all on MM, (even without amplify or xposed). All I've got are Greenify and Naptime by Franco. The main thing waking up my device is Google Play Services Alarms, (related to Google Cloud Messenger) and that's understandable, as Google Play Services is the only package that is 'not optimised' by doze in the battery optimisation menu. The CPU states say that my device is in deep sleep almost the entire time that the screen is off, which means that doze really is doing its job. Only thing left to be desired is a rom + Kernel setup that is battery friendly during screen on, but that will come as MM roms exit the Alpha stage.
All this being said, I feel that MM does a much better job with battery than majority of LP roms. Only thing that's come close in LP for me is a heavily optimised setup with Sultan's CM (+Greenify, xposed, amplify, etc etc).
By how Google advertised Doze, you should not be losing much battery when its in Doze mode but that isn't the case. We are able to enter deep sleep on our devices but we are not able to enter Doze.

I'm on stock cm 12.1 not rooted and I loose only 2% battery at night.. Very rare its 3%. By what you guys are posting, I think I'm better off with stock rather than marshmallow
I have not test MM roms
But from my little expirience from donut android version to lollipop
you testing different various settings
Any upgrade hide new hardware support
First was
better camera like dslr
After was cpu cores and power
Leds
Faceunlock
.......
Greenify, amplify was growing up fast beacause older or middle range devices could not handle upgrades
MM has bluetooth standby wifi standby fingweprint standby
Even if you switch off code is there and system kepp reading
All rhis various hardwares consumption without this new feature without simmilar tricks will conssume your bateery in half time
Even to lollipop if you switch off wifi stand by will gain 2%more at standby
I think DOZE isn't included in 6.0, or isn't optimized. In CM12.1 I lost 1-2% overnight, in CM13 I lose 4-5% overnight. DOZE is a Google / Android trade mark lie.
you guys should try Omnirom, I think they got it working
I'm running omni and pretty sure it is working. after leaving it off charger the other night, I lost 1 percent and it checked out in bbs .2%/hour drain. the best I had on lollipop was .5% and that was without Google installed. but I normally charge overnight so I don't have much more data, also been working overnights lately and use always on VPN, so need to keep watch on stats some more but that is my experience so far.

Something must be different in your set up cause overnight on Omni MM I get 1/2% battery drain overnight. As far as my usage dictates battery life at least in standby is much better than KK and LP. I don't use Naptime/doze editor or any random apps for triggering doze instantly. It's easy to make sweeping statements like you did in the OP and in subsequent posts but your experience isn't representative of everyone else's but its a discussion thread so I guess it ok.

That is weird, it is troublesome to check battery life consistently cause I'm flashing very frequently, but what I have observed, I was on Sultanxda's CM13 build, probably last week, checked battery level, it was 46%, aggressive doze was on through Greenify, and I usually do a lot of tweaks here and there to increase battery life, woke up 6 hours later, and guess what, 46% !!! Probably it was at the beginning of 46th % before I went to sleep and by morning it was edge of 46th % but that's less than 1% in 6 hours. WiFi was on, and selected 3-4 syncs were also on.

You're right probably just means you lost less than 1% during that period which isn't strange in my experience. The norm on MM is 1% or less IOW flat battery graph in stats

Yep, flat battery graph in stats indeed. But it still takes a substantial hit due to mobile radio active bug, what I notice, it is more severe in some ROMs and less in others. So, yes, I believe doze is working, is it so great as per the hype ? Yes, cause Google only spoke about idle battery drain, and the idle battery drain is really less.
Probably tonight I'll check how good it does with 3G on and WiFi off, how much it works with mobile radio active bug.

MM battery life - back to 5.1.1 for me

So I have updated to MM 6.0.1 and experience bad battery life. I have done a factory reset 2 times and still losing approx 1.5% of battery per hour and only seeing the phone go into deep sleep approx 50% of the time according to better battery stats. Before the MM update when I was on lollipop I was seeing a battery loss of about .7% / hr and 90+% deep sleep time for similar usage.
I have disabled all of the bloatware I can (including facebook and flipboard) but still no luck. I am going to go back to 5.1.1 unless someone has any other ideas on what is eating through the battery life with MM.
My battery life has been awful also after the MM update. In fact, it has been terrible ever since Kitkat. I have tried different batteries and hard resets, nothing helps. I am going to try another hard reset because Bluetooth is draining my battery like crazy even though I am not even using it (#1 drain right now). The software for the note 4 has been such a huge disappointment!
great b life, i dont use bluetooth...i really like this update
do you use Package disabler ? i have probably 12 apps disabled..helps a great deal
I do use package disabler and had many more that 12 packages disabled but even with BT off I was seeing a 1.5+% drop/hr. I have now gone back to 5.1.1 to test it out for a few days and verify that battery life is back to normal on it.

can anyone tell me if the marshmallow update gives us android users? i know users are not available in 5.1.1 but was hoping it would be in marshmallow.
I've been getting great battery life on MM but I'm running an S7 port on my Note 4. I'm currently at 1d20h with 6% battery left.
Battery life is usually not too good after a factory reset. Give it a couple two or three days and then re-evaluate.
I've been on the Jasmine ROM for about a day and for me, battery life isn't that much worse than it was when I was on 5.1.1.
Also keep in mind the age of a given battery. Like a new car, as soon as you roll it off the showroom floor it begins losing value.... LiOn batteries have a limited number of charge cycles, and after the first handful, you can pretty quickly see faster discharge times. This is accelerated with heat, which tends to happen when you install a new ROM, because you're hitting the screen and processor pretty hard for long periods of time. Also, avoid charging the battery while the phone is hot, that will also accelerate the wear on the battery.
This is one of the reasons the Note 4 is still a great phone today: removable battery! Get yourself a replacement or two, they're cheap and it's always good to have a spare on hand.

I did give MM several days to settle in after a factory reset but still no better battery life. I do not that if you are on JasmineRom that you must have rooted the MM version to install it. I am considering doing the same but was concerned that I would not see any better battery life with it either.

Why I went back to Marshmallow (Answer: Battery Life)

So I had Nougat ever since it came out and used it a lot, but went back to Marshmallow a couple of days ago because of:
...Battery life. No matter what apps, settings, versions (B360, B380, B381), recommendations etc. - Battery life is simply better and more reliable on Marshmallow. Yes, I know, I did factory resets, downgrade, upgrade via OTA, deactivated this and that, pretty much everything you read on the threads here and elsewhere, it still couldn't catch up to Marshmallow. Don't get me wrong, battery life on Nougat is not terrible - I even convinced myself over the months that it is pretty much the same or even better, but that's simply just wishful thinking. As soon as I downgraded I could notice a significant improvement.
What do I mean by improvement? For once it is more reliable meaning I know what I get. On Nougat I had days where I got 3 hours SOT, then 4 or 5 on others. I had 2 percent stanby drain per hour, then 5, then 1 - it was just more random. On Marshmallow I always get pretty much the same. Stanby drain of 1 percent or less per hour and SOT of 6 or more hours (I'm at 3:40 SOT at the moment with 18 hours and 45 minutes since the last charge and exactly 50 percent battery left). So not only is it more reliable, it also gives me more SOT and lower standby drain.
Regarding the standby drain: When installing apps like ForceDoze on Marshmallow, it lets the device enter Deep Doze the minute I turn off the phone (meaning I often have deep doze rates of above 98%) which leads to little to almost no standby drain without losing any benefits (notifications still come through when added to the whitelist). Deep sleeps rates are also above 90 percent. With Nougat deeps sleep rates are only around 80 percent (given the same apps, settings etc.) and doze rates are much worse. Yes, I know all about light and deep doze, but light doze doesn't start until 5 minutes after the device is turned off (even with apps like ForceDoze) and those 5 minutes add up, especially if you are checking your device often. Also, it doesn't enter deep doze which arguably consumes less power until much later (often hours) and there is also no way I could change that with ForceDoze or Greenify. What's more, the ForceDoze setting of "ignore device movement" actually works on Marshmallow but didn't reliably work on Nougat meaning the deivce enters and stays in deep doze the minute you turn off your phone even if you are moving or driving etc. This made the difference between Marshmallow and Nougat even greater for me when driving or walking around town.
One additional thing I noticed. is that Android System and Kernel (Android OS) usage was higher on Nougat than on Marshmallow, which also worsened battery life on Nougat for me. Again, this could be reliably replicated with the same apps, settings etc.
Granted, everything else is pretty much better on Nougat (speed, UI, notification bar, lock-screen, security updates, additional features etc.), but if you value battery life above everyhing else (which I do), I still think Marshmallow is the best on the Honor 8 and, frankly, I don't see the point of updating to a newer version of Android if it doesn't come with at least the same battery life, as it is one of the most central features of a phone. I don't know and don't really care whether it's Nougat itself or Honor, I just hope that eventually (maybe with B38X or B39X), battery life will fully match that of Marshmallow. What do you guys think? What's your experience?
I never used MM longer than a day or two before upgrading to N, so I can't comment on which is better, but I can confirm that (with N) I've seen random days where the battery drain is unreal during standby, and other days when it hardly drains at all during standby. But ever since I performed a factory reset after upgrading to N, the drain has been very predictable. Standby drain is minimal and SOT is 6+ hrs. Hard for me to complain when I couldn't get that much SOT from the Sony Xperia Z3 Compact on KK, and that was a battery champ! I finally feel like I'm getting the newest features and great battery life at the same time.
You need a choice for people who never used MM in your pole to make it more accurate.
My wife just got her Honor 8 today. It's on Marshmallow. Mine is on the latest Nogat. Each update killed my battery life not significantly but noticably. I can relate to you wanting to downgrade.
While I never had an Honor 8 with Marshmallow, I was about to update her phone to the latest until I saw this thread and am glad I didn't. If Oreo fixes battery life issues, I'll happily update both our phones to it.
For her, this is her first Android and is coming from Apple. Last thing I wanna do is give her an excuse (battery life is a great one) to go back to Apple.
And the funny thing is....she doesn't care about the app tray like most of us Android users lol
Let's see how this pans out!

An older battery compared to a new one. One lasts longer, that's so crazy to think batteries might depreciate over time. ?
I bet you think you can kill your battery by leaving it plugged in too.

Marshmallow vs. Nougat Battery Life

Hi. I am still on Marshmallow and am constantly being asked to update to Nougat. I am reading the battery performance / on screen time i snot as good in Nougat as it was on Marshmallow. Can you share your experience? One of the reasons I needed this phone was for battery life and I don't want to lose that.
I think mine might be less on Nougat than MM. But, I'm using different apps lately that seem to keep the phone awake more frequently. I'm easily still getting 4-6 hours of screen time from 4:30am to 10:30pm and going to bed with 25-50% battery. Again, it depends on how I used the phone during the day.
Yes, it seems a little worse than MM, but I know I have apps since switching to Nougat that tend to wake the phone more frequently.
I'm definitely not complaining about the battery life on this phone. I often go 40 hours without charging.
So you mean even if there is a difference it is minimal?
Also, do you have the US version?
Yes, US. The longest I went was 3 full days without a charge. Something like Monday 4:30am to Wednesday 10:00pm. Just shy of 9 hours screen time I think.
The difference between MM and Nougat was very little. Honestly, the UI is much better in Nougat than MM. (granted, it still needs work) Positive Nougat UI changes outweigh the battery life change.
Look at it this way... How much use time do you need a day? You should be able to still get 5-8 hours easily depending on usage.
I feel its the same, I've not fully measured it but I'm still getting from 3 to 4 days of battery after Nougat. I mainly use the phone for receiving calls, whatsapp, instagram and twitter, actually Twitter is the app that I use the most.
Right now I have 75% left and still tells me it has 3days of battery left, so that still a great battery duration
Well. I'm on board now too. And you all are right: no noticeable differences at the moment, although I did wipe cache and all data via recovery after update. Liking this phone.

Oreo battery life

I can't cope with this bad battery life that came with Oreo. I'm not a heavy user and I do have Bluetooth enabled because of my Gear S3 - but at this rate I need to recharge my phone twice a day...
I've already done a restore, removed all unnecessary apps, replaced mail Push to 15min and other changes for a better battery life. But nothing helps.
Do you also have the same issue?
I personally have exrltraordinary battery life 6 H SOT.

yea battery life kinda sucks and i have not hooked up all my apps as yet ..
auto brightness seems to be stable and a bit better but the battery is horrid i left home at 6:20 am with 100% i'm already on 53% with bluetooth audio and whatsapp really.
I did a factory reset after my upgrade.
Battery endurance is better than N.

turn of "mobile data always on" inside Developer Options and see.
Can someone on the internet identify this underlining issue of battery getting exhausted so rapidly. On Nougat it was just fine but after updating to Oreo, battery backup is gotten worse. Whenever I see battery stats Android OS and Android System using absurd amount of battery just below the screen usage time and sometimes either of them is on top in usage.
I have done numerous resets with and without data restore. But nothing changes.
I think have found the problem. Samsung Email, after Oreo this app keep on in background every time (do not look in battery monitor but in applications) . I already try one day without any mail app and the gain is enormous and other one day with other mail app (Gmail) and the gain is also enormous. For last day (tomorow) I try again with Samsung email for confirm the result .
Same problem here but with my S8+. Went from 7h SOT to 4h SOT. I also deleted samsung mail app and replaced it with gmail but even that didn't really fix it.. Other than that Oreo is really good in terms of performance, but I want my old battery life back. Hopefully Samsung will fix this with the next update.
I am really surprised some people have better battery life with Oreo. Maybe it has to do with Snapdragon vs Exynos ? I have an S8+ with Exynos CPU
I had great battery life with Oreo beta 6 but then I "upgraded" to the final version CRAP and my battery life is now a crap!
Currently on my S8Plus(Exynos) I am unable to get a full day of battery backup with moderate usage. SOT usually lies between 2-2.5hrs max in 12hours on battery.
Also I don't have Samsung Mail App. All things stock with limited no. of 3rd party apps likes social media apps, 2-3 shopping apps and also 3 gmail accounts synced.

For last day (tomorow) I try again with Samsung email for confirm the result .

Hi I went by your suggestion and checked in apps to see which one were consuming the highest battery & my culprits are Bixby Global Action & Bixby Service each consuming 11% each (Please see attached files). I am also attaching usage statistics of today. Both before disabling services and after disabling. (See the time to figure out). Will get a better idea tomorrow.
Suggest everyone to look in to their apps usage and post their findings.
EDIT: I just checked I had used the STOPPED the applications but forgot to disable them. Have disabled them now at 17.45 PM and will update later.

Be careful the percentage of consumption of this app is a is a consumption of many app from "android system "
But it's not worth to disable lot of Bixby
