PDP firmware

Did myself a factory reset including storage wipe from custom recovery yesterday...just wanted a fresh OS. I noticed that even (fast) charging became slower then usual. After work I charged my phone to 100% and went to sleep. After around 7h 30m of not toching it at all my battery was drained to 30% in the morning. WTF?! I never had this issue before and used this firmware for months now. Only difference is I had root before. Android OS was at the top of list for battery usage.

I also noticed that WiFi may somewhat be the issue. After turning it off it charges fine but with WiFi ON it becomes slow again even when I have Fast Charge always on. Im charging my phone as I write that and it came from 4% to 73% in last 30min.

So - 1 hour after charging to 100% with WiFi ON, DATA OFF, GPS OFF battery dropped by 9%. WiFi wasn't even connected as I was driving to work :-/

Updating via Smart Switch and once it's done I will edit this post.

EDIT:

Updated the software via Smart Switch and everything is like it should be. No more insane drain.

All I did after installation of SmartSwitch on my PC was to connect my phone when it asked for it and it told me that new ver of firmware was available for download. From there just follow the instructions.

Finally I put Active Sync to off, Wifi off during Night...
[Galaxy S6 Q&A, Help & Troubleshooting] jaswinky:
Negative. Today I made some test on wifi and now I think it is nothing to do with wifi. But I found something... check settings/screen and check if any smart stay, adaptive display (on screen mode) and/or "keep screen off" are enabled. If so, try some hours with these three settings disabled (set screen mode to basic) and then enable them again one by one. I did it today and once disabled and now with all these enabled again the slope of the battery graph is OK, really better than yesterday.

I suspect of one of these three settings (I am not sure which one because I disabled all three at same time), maybe "keep screen off" which I remember I enabled some hours after updated to MM and started my bad battery response, could have any bug and need to be reseted or something like this.

If you test it share your experience.

Also I released that basic screen mode has better battery consuption than adaptive display, it would be useful in case of low battery emergency...

Had serious Android OS drain after the PHN update. Did a factory reset and things got better, but it's still always second in the list with >15% of battery usage. Gonna try your suggestions jaswinky!

Edit: I already see my battery stats being different now, with Android-system at 11% and Android OS listed 4th at 10%. Android OS usage has never been this low since the MM update, and never this low on the list. Looks promising so far, but should wait for some complete cycles.
[Galaxy S6 Q&A, Help & Troubleshooting] jaswinky:
OK, yesterday I tried to disable smart stay, keep screen off and adaptive display, and then enable them again. At beginning battery response were fine, but today it went back to a bad response, any process of one of these settings maybe hangs. Then I disable only smart stay and perfect, good battery response again. Now I am 90% sure this feature is the responsible of, in my case, my battery drain (maybe the process hangs when screen off), but I need to be a complete battery cicle tomorrow with smart stay disable to be 100% sure.

Here first slope with smart stay enabled, and second slope (flatter) with smart stay disabled:

[Galaxy S6 Q&A, Help & Troubleshooting] Jessie.boi:
I have experimented this with wifi on and without wifi on. It still does persist. Battery drain without wifi is still significant 15% drain after 7hrs, Android OS still the culprit. I dont think the wifi is the culprit. Also i testify with previous comments that the battery management roght after marshmallow update was excellent, ut was days after the update that thing went south. Hope we can find a fix on this
[Galaxy S6 Q&A, Help & Troubleshooting] dsaklein:
I have asked the same question yesterday:)

I'll try with smart turn off. But in my case I have an international version, Android system consume 50%-60% if battery, and as I said in post I have done cache clean it helped but only until I charged my phone, after that it returned.

Could someone tell me before that one I have had an s3 and when smart screen is on there was an eye at notification bar but on this phone there is no one is normal or not?

Sorry for my bad English

[Galaxy S6 Q&A, Help & Troubleshooting] dsaklein:
Well, i have just contacted Samsung support, and they said that Marshmallow should work excellent on s6 without any battery drain problems. And if there issome that we should try to reset phone
[Galaxy S6 Q&A, Help & Troubleshooting] dsaklein:
As I said before I have cleaned cache and rebooted my device and deep sleep start working, but after I charge my phone and disconnected charger it's stopped working again, and only solution after that is to reboot device again. I don't know how to solve it except to try hard reset . Did anyone tryed it?
[Galaxy S6 Q&A, Help & Troubleshooting] zlobich:
I have the same issue. Did hard reset,flash it with ODIN,ran it in to safe mode,nothing helped. It is annoing to restart the phone after charging it,to prevent battery dtain,and enable deep sleep.

The problem ocurred after the last update for my country. It is interesting that my wife has S6 too. Did the same update,her's phone doesn't have this problem. Any Ideas how to fix it?
[Galaxy S6 Q&A, Help & Troubleshooting] dsaklein:
Yep it is very annoying, but I think that we should wait until Samsung fix it or until someone find a fix for it

[Galaxy S6 Q&A, Help & Troubleshooting] Jessie.boi:
I will give this a try. Fyi, the recommendations on the previous page such as turn off smart stay, adaptive display, wifi off and turn on keep screen off, has not worked. I left my s6 at 100% batt before going to sleep then after 7hrs, I woke up with 70% battery with Android OS still the hogger at 75%. Will definitely give this suggestion a try later.

I dont know about you guys but it seems to work for my s6. Disable fast charging and then reboot. I left my phone for 3 hrs and battery lost only 2% with Android OS absent at running processes also, I took a screenshot of my battery graph but i dont know how to upload it here. Will still be monitoring my s6 behavior during overnight sleep.

Yep, i was wrong sorry. I have even changed my software through Smartswitch and Kies, and still nothing helped, after i unplug my charger deep sleep is disabled.
[Galaxy S6 Q&A, Help & Troubleshooting] donkito:
Hi guys,

I am really sorry to read the whole thread. :rolleyes:

I have got the problem for a week now. Everything was working flawlessly (I haven't downloaded anything new) and one day I realized that my battery went from 100% to 75% over a night (7:30 hours). Normally it has depleted by 3-4% for the same amount ot time, but I've noticed that the phone just cant enter deep sleep.

I've tried many of the things suggested in the thread even before saw it exists, but there is no effect overall.

I will follow the thread carefuly in case somebody find a solution for the problem.

I hope that we will "cure" ourselfs and start to use our phone as intended once again! :)

Hi guys I just want to share this battery graph after I performed factory reset. Yesterday, I performed factory reset (lost my contacts btw, google sync seemed to malfunction) and have not installed and updated any apps beside those auto.updated by android. I left my phobe fully charged idle overnight with wifi off and woke up still 95% batt. I also noticed that there was no Android system/OS process present below the graph. It was a relief after weeks of battery drain. 2nd overnight test later, hoping for same results.

Hope it will help you too, oh yeah and I have done it in Saturday so it's been almost three days that my phone works perfectly

Well Kies is incompatibile, but Kies3 is compatible. And it's not 3-4 hours if you have decent Internet speed. But for me it's worth it, my phone runs smoothly like never before it charging even quicker then before and deep sleep problem is gone.

And you can't brake knox counter since its an official Samsung tool which install official firmware

[Galaxy S6 Q&A, Help & Troubleshooting] skyhors3:
problem is coming from WiFi, tried disabling it overnight and only lost 3% which is heavenly compared to 40%.. running fully stock nothing installed on my part.

could Samsung be deliberately doing this to make us buy their new phone?
[Galaxy S6 Q&A, Help & Troubleshooting] bett3rthan:
Their new phone has same problem, and I dont think is coming from wifi since I dont keep it on very often. And the thing is I dont have this problem anymore if a restart the phone right after charge, and than again when is 95%. So I think its something from charging, a service that starts when the phone is charging, and doesnt stop when its finished.
[Galaxy S6 Q&A, Help & Troubleshooting] DarkNate34:
Okay guys, I've narrowed down the issue.

I was surfing the web and used the YouTube app to watch videos, Android OS used less than 25 mAh.

I played an online game called WWR, Android OS used about 10 mAh.

I put the phone on Airplane mode and watch HD videos on VLC, Android OS did not show up on the battery statistics.

So here's where it gets interesting, I've closed all other apps and services I'm using Greenify Donate version. I got on Hike, WhatsApp and Facebook's Messenger, started texting with people. In a matter of 60 minutes my phone went from 100% to 60%. Android OS was killing the battery with over 100 mAh battery consumption.

It looks like any app with GCM support will cause Android OS to consume a significant amount of battery.

This is definitely a bug.

And yes guys, I've tried using only one GCM app per charge, same thing, over 100 mAh battery consumption.

Don't bother asking for screenshots. Test it out yourself, avoid any GCM app and see how long your battery lasts, then do the opposite.

Some reputed developer needs to find the technical reason behind this and report it to Samsung.

And yes, I've disabled the GPS completely, didn't see any changes at all.
[Galaxy S6 Q&A, Help & Troubleshooting] bett3rthan:
Is viber a safe app?
