I'm on my second day with BPHC (dirty flashed from BPH6), fully charged in the morning and when my work day is over now (a little more than 7,5 hours in use) I find that Android System is at 14% and Android OS is at 7%. This is with the phone staying on wifi most of the time and I with a few phone calls which laste for just over two hours total (this on good 4G coverage with Volte active)

The battery sits at 48% now with a SOT just over 3,5 hours and as mentioned just over two hours phone calls. I'm quite impressed for the time being, this is one of the best results I've had with my S7 Edge since I got it, even besting my time on APC8.

I posted some more info in the battery life thread with screenshots from when the phone was at 62% battery life and about 5,5 hours of usage:

Interesting... Do you have autosuync turned on??

Thanks!
[Samsung Galaxy S7 Edge Questions and Answers] Cst79:
The problem is that you can get a good SOT with pretty much any firmware, the real issue is the standby time. I hope Samsung did improve things in the BPH* firmware since the Note 7, but I am not holding my breath.
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
Since APGH until now standby is good.

During night with wifi on 7 to 8h

2%.

I post in other thread a few days.
[Samsung Galaxy S7 Edge Questions and Answers] kl0ndike:
15% is too high for Android System. Should be 4-7% (As mine on old march firmware)
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
I already forget ACP8 its good for wifi but in 4G is bad, android OS is always eating the battery in 4G and no standby.

If you have a good standby it always have better battery.

I try a lot of roms and for me until now XSA is better than ACP8.

My use is always 3h to 3h.45m sot until 50% in 4G. With auto brightness.

Last twice my old s6.

This is how is now.

Is stable android system and OS.

I can't remember if this has been posted before but I'll bring it up anyway. After taking the phone off the charger I would get a huge drain. I was going into recovery and clearing the cache to fix this problem. So recently I decided to turn off Bluetooth after charging and find that the phone wasn't draining quickly anymore. I turn it back on after a few minutes and Gsam says i have over 300 hrs on standby. So the phone is going back into deep sleep. I am on Verizon in case you need to know but may not matter. Hope this helps some people.
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
2h on wifi since left 4G and android system still on 9%.

I test it one thing and syncing Samsung cloud android will go high more fast.

I have just been notified of the BPH6 update and installed it over my current APC8.

At first sight things look pretty bad compared to APC8, I would advise anyone thinking of upgrading from APB7 or APC8 to the latest BPH* to not do it yet. Both Android System and Android OS percentages are very high (I don't want to post the numbers because it is just too early).

I will post a battery usage comparison between APC8 and BPH6 in identical conditions in about 48 hours (waiting until full battery drain).

Please note, I do not use any battery optimization methods with my phone, things are pretty much as they came from factory (sync on, Bluetooth always connected to smartwatch, location on but set on "gps-only", Google backup is "off").
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
For what i try sync contribute to high android system., Google back don't do nothing , could do if the sync is on.

But i dont use sync on i really dont know, only use before factoryreset.

I receive my emails with sync off.

For me using my moto 360 v2 is just the culprit of battery drain. It literally doesn't allow my phone to doze at all. It's pretty sad that an accessory supposed to help you to use your phone less and increase your battery life (indirectly) bugs so much, I don't really know if it's Samsung software fault or just bad designed MM/Android Wear.

As I also said previously, for me Spotify seems to also prevent the OS to deep sleep and doze. The way they implemented the app when you're listening music on other device and getting this information on your smartphone even if you didn't open the Spotify app is so dumb cause no deep sleep/doze and massive battery drain.

So I'm gonna test this week: no smartwatch and force close Spotify when not using it.. I'll report back. :confused:

PS: I'm latest XSA clean flashed (august security patch).
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
Yes how you use the phone never goes to deepsleep , its how i do some times, check messeges. , 5 minutes later check again , battery will drain more and sotf worse.

But the doze work very well im on latest XSA too, and this night drain 2% almost 9h with wifi on. I dont ask for more.

Android system is at 12% .

What i notice from other versions is this XSA Google services drain a little bit.

I never get more than 3% now im on 9%.

Same settings all Google crap disabled.

Here is deepsleep

I've got 2% battery gone on airplane mode tonight.. :(

, if you have bad signal always better airplane mode.

I never had this standby even with old s6.

Could be the doze is working good.

Its strange with this rom never get android system over the screen.

I want you to see one thing and report after,

You count the android system , android OS and the phone standby all together and tell me how much mAh they spend until 50% and to 1%.

Because i had count some firmwares and in the end its always around 1000mAh .

Around100mAh per 10% battery.

I really like to know from other users, because when I had ACP8 android system was low but OS goes high and in the end that 3 always were around 1000mAh .

If you see mine now i had a first 10% live streaming in Facebook drain a lot, now im at home and all 3 gives that 85% 147mAh .

APC8 vs BPH6 firmware battery life comparison

Here is my battery life comparison between APC8 and BPH6 firmware, with screenshots.

As you may know, APC8 is the last firmware with low Android System and Android OS usage.

- I have not used any power saving method. No apps disabled, everything is on, including sync, location, bluetooth, etc.

- Basically I think BPH6 is better than APC8 at battery life, and there is no reason to stay with APC8 anymore

- Especially in 4G usage, the BPH6 is much better than APC8.

- You can easily obtain 48 hours standby and 4.5-5 hours SOT with BPH6 (it was more difficult with APC8).

- Indeed, Android System and Android OS percentages are significantly higher with BPH6, but it does not seem to matter.

- With BPH6, I lost the ability to use the double tap to sleep (Nova Launcher has this) and then unlock with fingerprint. It requires the PIN code instead, which really sucks. So I disabled the fingerprint unlock.

Attached you have 4 screenshots: the first two are from the BPH6, the last 2 are from APC8. As you can see from the screenshots, the APC8 has 30 minutes more SOT and the same standby time, BUT the BPH6 was used for around 8 hours with 4G while the APC8 was used for only 2-3 hours during the test, which is a huge difference. If I used the APC8 for 8 hours in 4G the standby time would suffer alot.

So basically, my advice is to upgrade to the latest firmware (BP*).

Also note, for maximum battery life disable the Quick Charge and use a very good 2A cable (it will charge in 2 hours instead of 1.5 hours but the battery life will be much better).
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
That's good.

Can you see how much mAh are using android system and OS and battery standby all together and how much battery you have left.?

Thanks
[Samsung Galaxy S7 Edge Questions and Answers] Cst79:
Sorry, I don't have this information as I have charged the phone. The only useful information I have is the one from my comparison post.
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
Ok.

When you have 50 you can see and report ok.

Thanks

I'm experiencing high android system drain. Any fix for this??
[Samsung Galaxy S7 Edge Questions and Answers] hamer221:
Thanks man. Where can I get that cable? Isn't stock usb cable good enough?
[Samsung Galaxy S7 Edge Questions and Answers] Cst79:
If the stock USB cable tells you that the phone will be charged in 2 hours (and not 7 hours) with Quick Charge turned off, then it's a good cable. But my stock cables behave erratically: sometimes I get "2 hours", sometimes "7 hours". I currently use a Kindle Fire 2A cable.

However, please note, after some more testing it seems that APC8 is still better at battery life, I have to do more testing but my confidence in the latest BPH6 firmware is dropping fast. I will post an update in the following days.

I own s7 edge exynos. Battery life is fantastic i get 7 and a half hours sot. I'm on superman rom.
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
And about the battery is the same or its bad?

I try a lot and usually when the android System and OS and battery Standby all together are less than the % of the battery is good.

If its more is bad.

Ex.

Android system 30mAh + android OS 40mAh + 20mAh battery standby = 100mAh for 10% battery, if its less its better.

This is always with wifi on or 4G on.

Try it and let me know.
[Samsung Galaxy S7 Edge Questions and Answers] biustech:
well, to be honest the battery it's about the same, but your math in my case would be like this: Android system 459mAh (16%) + Cell standby 217mAh (7%) + 174mAh (7%) and i'm 1d 5h on SOT 25% (4h) and left 14% total battery. wifi and 4g on

but the thing is, Android system before BPHJ was ok always less then 10% and now 3 days always above 15%, i think there are more process running in background with this latest update but i can't disable them :(
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
Yes im right your values give 851mAh with 14% left.

You will follow that values with different usage and post here.

What im trying to say is no matter what SOT you do that 1000mAh are always spend on that 3 things.

The rest is apps or brightness.

Yesterday i post 60% battery with almost 5H SOT but only wifi and always auto brightness were maube 20 to 50% At home.

Brightness and heat coud do major difference.

I arrive now at home with 5 %

Today was the first day i use the phone always outdoor full brightness and 40 42 degrees on the battery.

Always on H+ because signal was bad.

And lot of calls.

And still get 5h sot.

As you see in the screenshot SOT is more than twice mAh .

But hang on until get home ?

Because full brightness the values get down a little bit.

But normal is 1000mAh 100% battery.
[Samsung Galaxy S7 Edge Questions and Answers] HeaDShoTHuntR1:
I used to have 5h of SoT easily, now i might get 2-3 or something.... i have all the right settings i guess; location on powersave, backup& sync, ... I have no real app that is draining my battery. Cleaned cache partition already.

Android system is my highest drain - about 20-25% most of the time.

BetterBatteryStats shows that my phone doesnt enter deep sleep and stays awake most of the time.

Currently not rooted, if someone recommends a ROM that has better batterylife, feel free to do so :')

Any help?

[Samsung Galaxy S7 Edge Questions and Answers] _dsouza_:
This is Doze active. It is very likely your phone was stationary during this time. If it is in standby, but in a pants pocket while you are walking, for example, Doze will not kick in and the standby battery consumption will be higher than this.

And that's my problem. While my phone is most part of the day in standby, I carry it in my pocket and I walk very frequently within the office, and this prevents Doze to kick in.

Only with Android 7.0/Nougat we will get "Doze on the Go" which should improve battery consumption in standby but with phone in movement:

You can use Greenify which has "Aggressive Doze" and the latest version lets you enable Doze on the Go by granting DUMP permissions via adb. Works great for me.

Well, I upgraded to Galaxy S7 from an LG G4 (dual H818P). Here in Brazil LG released Marshmallow to this model only in July/2016 (so 9 months after the official release).

At least my Galaxy S7 already received 3 security updates since I purchased it 3 months ago.

But yes, I am not holding my breath waiting for Android 7. I have a Galaxy Tab Pro 8.4, which was *never* updated (Samsung released it with Kitkat and never upgraded it). :mad:

I am constantly having problems with deep sleep. Sometimes the phone goes to sleep like it should and the battey life is acceptable. The other day the phone nearly won't sleep at all and battery sucks. I haven't mase any changes to apps, settings, same scenario. The coulprit seems to be play services. As soon as I clear data the phone seems to sleep again. I have already turned many settings off only use my gmail, locatiom etc. I'd like to know if disabling permissions for motion sensor, calendar, camera, etc any affect on battery life or functionality has.
[Samsung Galaxy S7 Edge Questions and Answers] neezy13:
Have you tried restricting background data for Play Services? I did that and it really brought Play Services battery use under control. I went from Play Services being reported at 23-24% to around 5%.

Another issue that I had was that WatchMaker was hung up polling for a weather update for my Android Wear watch and that was keeping the phone awake. Changing to a different weather provider solved that problem. Could be a similar situation with some other app and Play Services is showing it because the GPS is bundled with that.

I totally give up on this phone. I unplug from charger every morning, reboot it then bluetooth pair with my watch then with car bluetooth. By the time I get to work battery has already dropped 5% with no sot at all in less than 20 minutes.

The idle drain is bad (I'm on latest BTU (BPHJ) september security patch, full wipe + clean flashed).

Doze? This is a joke doze never kicks in with this phone unless I sit it on airplane mode while I sleep.

I'm getting down to 40% from 7 AM to 10 PM with 1h-1h30min of sot (20-35 minutes of gaming).

I'm not angry because the phone drains when I game or use it, it's all about this nonsense standby drain from Android System that can end up with more than 4h of CPU time and more than 25% of battery around 9pm.

I've GPS always off, bluetooth on when I'm not home (paired with my moto 360 v2) and sync on (just syncing one gmail and google keep)

And before you ask at work I've full signal and at home since I've really poor signal I'm on airplane mode + WiFi.

This expensive phone will last one more year then I'll swap for something else. Unless Android N update fixes some of this buggy Samsung firmware.
[Samsung Galaxy S7 Edge Questions and Answers] biustech:
I'm on the same boat mate, in my case, I unplugged 8:00AM and finish my day around 10:00 PM with 30% or less with Bluetooth on with headphone paired and listening to radio online , sync off, location off, SOT around 1 and half hour (used with whastapp, facebook, and simple stuff).

Android System up to 15%, i tried to limit CPU clock, but didn't change much. only thing left is to try custom roms, or wait for updates to fix this (not counting much on that)
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
For what I had tried, BPHJ is good in wifi but doze doesn't work, i return to BPHC XSA and doze works.

About the sync if is only for emails just leave it off and use the app MAIL.RU

Its the best.

And disabled everything from Google apps settings everything.

If its sleeping in wifi Android System don't get high.

I left wifi on during the night, get some emails and notifications and drain 3% over 8h.
