Hi,
Been trying to figure out battery drain on my SGT 7.7 P6810. The battery drain when off is high and it appears the device is never going into a deep sleep.
Any help / ideas?

Fully charge the tablet. Use it as you would on any other day, but don't recharge it. When the battery is at a few percent, get a BetterBatteryStats log, and then post it here (actually, post it along with your tab configuration at the BetterBatteryStats thread, where you will see people who know each possible wakelock by heart.
Your log has only 40 minutes of activity. You lost 2% over 40 minutes of active usage. Statistically, it's impossible to say anything at this point.

Battery drainage has been a major frustration for me with my phone. The frustration stems from the many variables associated with battery drainage. For the most part the terrible battery drainage started after flashing the modified ROMs. I believe the stock ROM was respectable when it came to battery drainage.
I am not ignorant to flashing ROMs. I have tried everything to figure out this battery problem; everything to keeping stock kernals, to battery calibration (delete battery stats), to battery bump charging, to matching radio files with RILs, to limiting data syncing, charge cycles etc.
But I am noticing that some of you are able to get good battery usage from a single charge with these modified ROMs. With that said, I want to cut the variables down and see what those folks who are getting over a day's worth of battery usage from a single charge are doing. The best indicator for battery usage to limit variables would be the battery usage standby rate with data network on.
I am not getting any better than 8%/hour on standby for any of these ROMs. That is crap. I wake up in the morning after 8 hours and there is only ~35% battery left. Unacceptable. I figure no more than 10% should be lost in 8 hours of standby.
So for those who have good battery usage, please answer the following questions so that we can eliminate all the variables.
1. What is your standby battery drainage rate?
2. What version phone do you have (TMoUS or EUR)?
3. Clockwork Recovery version?
4. What ROM are you using?
4. What Radio and RILs are you using?
5. How many charge cycles are you doing after the battery calibration and before you are getting the good standby rate?
6. Are you using any battery saving applications?
Please help if you can. Everyone seems to emphasize speed and performance but battery life is number one priority for any phone in my opinion.
Thanks
I'm currently running the P3D Neon ROM. I was having the same issues you are having due to flashing a new ROM jsut about every day. The big thing I noticed is that the longer I stayed with the one ROM the better my battery was. But as I'm sure you already know that no matter what a smartphone is a battery hog anyway.
By the way have you tried this, I am using it and love it !

Do a charge cycle every time my battery dies
I use battery calibration app from market
No battery saving apps
Standby I have no clue lol it sometimes doesn't budge but sometimes I get 1% every hour and 1/2
Light use I get 26+ hours.
Medium I get 16+
Heavy I get 9+
Hope that helps.

I've had my phone a week and am using stock Rom. I've S-Off, Root and install backup. Overnite, the battery only goes down 5%
If I were u, I'd get Android Assistant from the Market and check that all apps are closed. Check ur start-up apps and clear ur cache before u shut down ur phone.

More than likely, there are apps that are not allowing the phone to sleep when the screen is off. CPUstats will show you how long your phone has been in deep sleep, as well as your CPU clock speed.
Here is what I would try out:
1-Get CPUstats.
2-Turn off the screen for the night
3-Check to see how long the phone was in deep sleep mode. It should have been for awhile if not, you have a rogue app that is bothering your phone while it sleeps.
To check your standby current:
So far, we cannot accurately see what it is. I dont know of any app that can for our phones. I do know that the values I see cannot be correct, otherwise my phone wouldnt be lasting long.
1-Write down your current battery capacity in mA/Hrs.
2-Write down the time that you put your phone into sleep.
3-Leave it off for an hour.
4-Wake it up and check the new battery capacity.
An Example:
I started with 1900mA/Hr.
I let it sleep for 1 hour.
I found that after an hour, I was down to 1850mA/Hr. That is 50mA gone, over 1 hour time. So my standby current was 50mA/Hrs.
Now this is only a crude way of judging whether or not your phone is behaving. Since the battery apps update capacity every 5 mins or so, you may not be right on the money, but you WILL know if something is BAD. Calculating 50mA +/- 20mA means the phone is likely sleeping as it should. Calculating 300mA+/- 20mA means something is USING your phone without your permission.
Youll need to find out if some apps are syncing (or trying to sync) while it sleeps. Or, your phone may be trying to improve your signal strength.

The anker battery will help but it is not solving the problem. We need to be getting around 1-2%/hour standby drain like some of you guys are getting.

I like this test, I will check it out.
Hi everyone, I was going to wait until tomorrow to post a question but something weird happened just now that changed the situation. I recently got a replacement, so I decided to root, run xposed and greenify. I was testing out the battery and it was doing fairly well. I got almost 2 days with 3 hours of SoT. This morning after unplugging I noticed Android System (or Android OS) was taking a significant chunk of %. However, it didn't seem as though my battery was draining a lot. I tried rebooting and charghing back upto 100% and it still kept happening. At times it was Android System and at other times it was Android OS.
I decided to download BBS since from reading the forums that seems to be a way to determine the culprit. At first BBS was showing a wake lock ratio of about 85% wake lock and 15% deep sleep. This was having the phone on for about an hour. It showed it being kept awake for about 40 min or so. The battery wasn't draining incredibly fast, but the stock battery history chart was showing that it was taking about 50% of the battery. I decided to just let it be and see how it does throughout the day so if it continues I can just post the log here. After a few hours it seemed to have gone away. While it was still showing that Android OS was taking about 30%, the wake lock/deep sleep was getting better where at this point after 10 hours it's about 6 hr 45 min of deep sleep, 3h 12m of wake lock with 1 hour and 2 min of SoT. The battery is at 71%. So, there doesn't seem to be an extreme drain. However, what was really strange was I was just looking though GravityBox settings (only added day to status bar clock, not sure if it was after that) and the battery usage just changed on the stock battery, and GSam, where Android OS is showing that it took 73% of the battery and even the screen which was on for an hour only took 6%.
Has anyone encountered this? I can post the log from the first hour and the log from now if anyone is willing to look at it. Thanks!
I'm rooted, with TWRP, xposed module with gravity box, greenify, and app oppsX. Those are my only mods.
derp. misread.
Hey Guys
i have a strange Problem
my last one plus one had a good battery life time but the sound buttons get brocken , so one plus change my mobile.
1 wekk ago i get my new phone, everything is working but the battery drain was very fast.
i decided to install blisspop with bueffola kernel tweaked it a little bit for battery saving and install BBS for wakelock detections.
I elimenate all the wakelocks that cause a fast battery drain and since that te battery drain in idle is minimal but when my mobile phone is on the battery drains 3% in 1 hour.
That's weird cause as i say i eliminate all the wakelocks that causes fast drains and use the phone most time for spotify and whatsapp.
And if i start to browse on the Internet the battery life drops even faster
So what can i do?
Am i do something wrong
or is the battery of this new phone crap and i'm so luckily to get a phone with a failiure battery?
Any suggestions would be nice and sorry for my bad english.
German or russian is better
on 50% battery i have something like 2h of screentime so i thing till 0% battery i will have 4h SOT and this is nothing (don't use the Phone much a saing above only whatsapp and spotify)
Well, to be honest, 13% in 4:30h is not "very fast" considering you had 30 minutes of screen time. Mine loses about 10% per 30 minutes of using the device, going by that there are only 3% unaccounted for which easily fit the 4h standby your device was in.
Anyway. In 4:20h of tracked time, you have 1h awake time of which you had 35min of screen time. The remaining 25 minutes can be split up in roughly 15min of AudioOutput and 10min for several wakelocks such as the proximity sensor doing stuff for 3 minutes, the phone doing stuff for 4 minutes, basically everything is accounted for. All in order I'd say.
What I spotted:
You are on Lollipop. Did you wipe after/before upgrading to Lollipop or did you dirty flash from CM11s?
Do you have the new Lollipop-compatible firmwares (they come with CM12) installed? Not sure they come with Blisspop.
BetterBatteryStats has the CPU sitting on 1500MHz for half an hour. Check whether you configured your system to stay at 1500MHz with screen on which of course would be crap, the CPU should idle at around 300MHz.
It seems you had the device shut-down and then booted. Booting up the device eats massive amounts of juice.
Android reckons 3 days of usage like that, what's not ok with that?
1. Yes i wiped it and don't dirty flash the rom befor i was going to lollipop
2. Not sure have the latest bissplop
3 Where can i check what i configured to stay at 1500MHZ , in the kernel settings?
4. i know i rebootet it once
5. The reckons of the 3 days is not true , it only affects if my device is staying in standy cause i lost nearly nothing (as you will see in the logs i posted in the spoiler.)
The first BBS log shows the Device fully charged at 100% with wifi and Mobile Data on. I left the Phone in standby for the night (8h) and i didn't lose any precent.
So after 8h standby i still have 100%
After 11 o'clock till now i used the Phone mostly for spotify , a few times Whatsapp and something like 30-50min for internet.
In the second BBS log you will see that i lost Bat.: -35%(88% to 53%) [4,5%/h] although the SOT time is only at something like 2h.
The SOT time of 4h would be total normally for me if my reckon of android would be 3 days cause this is the case on my lg g2.
Because i use the phone most of the really only for spotify.
So the main problem of my device is not the idle drain but the drain if the screen is on or spotify works in the background with screen of.
I hope that the BBS logs in the Attachment and the 3 pictures can help you.
Thanks for your help
Don't go by the sudden drop of battery percentage after staying in standby for a long time, eg. over night. The very subtle decline of the voltage over the course of the night is smoothed out and reported as 0% lost. Once you start using the device, and the change in voltage gets more noticeable, the situation is re-evaluated and the previous drop of 0% gets counted in and a sudden drop of several % over a short amount of time will occur. This is physics and by design.
As for the rest, I'm by no means a pro in reading BBS Logs but from what I see, yes you are on Lollipop firmwares/baseband so we're good. The device enters deep sleep just fine, excellent in fact. No major or irregular wakelocks seem to occur, perfect.
As for the daily usage log, I see 7:45h. Of which 4:10h in deep sleep and 3:35h awake, of which ~2h screen on and ~30min phone on. You lost 35% in that time, averages 4.5% per hour. This seems perfectly ok. This would translate to 7h awake time with 4h screen time. I seem to fail to see your problem.
Interestingly the frequency tops now at 1500MHz. Did you change something?
To take myself as an example, on my way to work, I lost 19% in roughly 45-50 minutes of playing ingress. I had about 45 minutes of screen time, GPS constantly active and of course constant data traffic. I arrived 2h ago, barely touched my device in those 2h and lost another 2%. This is more or less in line with your usage, 1-2% when sleeping, 4% when awake with screen off, ~20% with screen on. You're not happy? You reckon you had more on your previous device?
Thanks for reply and help
My goal is to have a few days with android e.g 2-3 days
SOT is not so important.
Important is that there is not hudge battery drain wenn i hear spotify cause it dosn't mather if the screen is on or off it drains hard
On my lg g2 it's not so hard
And no didn't change anything about 1500MHZ
Any suggestion ?
Greetings
EDIT:
Open the back cover of the Phone
The battery is bloated

Hello, guys!
I have a problem with my phone for the past few months and after clean flashing 7.0 Nougat it's still present.
My problem is that when I'm home, my phone drains not even few percent of battery. Specially when I'm sleeping, I can go to bed with 100% battery and wake up with 98-99%. BUT when I'm out, specially when I'm working since my work involves a lot of walking the battery just drains like hell and I mean like 7-10% per hour considering I don't even use the phone. Sometimes I will have 30min to an hour of screen-on time and after 10 hours of work I will be home with 15% of battery left.
Now I know that this is mostly to some rouge app that keeps my phone awake and drains my battery but I'm not really sure how to pinpoint it.
I will provide my stats from Bettertbatteystats and WakelockDetector if you guys can help me.
Thanks in advance!
Edit: I just want to explain that the straight line on the first picture with the batter drain graph is when I went home and left my phone on the table for about 3 hours. You can clearly see that the difference in battery consumption during my phone being in my pocket and on the table.

Maybe you are in a poor service area when you're at work, poor signal drains battery pretty quick because the device is constantly scanning and searching for better signal.
Or
You're using one or more social media apps such as Facebook, Facebook Messenger, Whatsapp, Instagram, Snapchat, etc.. These apps are constantly running/scanning for notifications and are well known for eating battery, especially on mid-low end and older devices because they don't have enough CPU and/or RAM to keep up efficiently. Judging from your screenshots, I would say that this is your issue.
