[Q] unnamed rom and entropy kernel. battery drain is really fast - AT&T Samsung Galaxy S II SGH-I777

So i put this unnamed rom v 1.1.0 over a day ago and also put the entropy kernel. after i did this initially i wasnt gettin any deep sleep but now after removing facebook widget it went into deep sleep. during the first day i got great battery life , almost 24 hours with one charge. then i charged it last night and now the battery life is pretty bad. it went from 100 to 90 within less than an hour with minimal use and nothing was really working... then i started playin music and that really drained the battery , but even after i close the music programs, they still show up in the partial wakelocks in betterbatterystats.. ive closed the app using running services , app killer and task manager but its still there.. and i have no idea how to remove it.. i tried to reboot but it still showed up...
also besides this the last time flashed unnamed rom on to my phone the same thing happened.. great battery life for the first day but horrible for the second day and so i had to remove it.. any help would be great? thanks

Exactly the same combination.
Still testing this but I do think the battery is dropping really quick.
4% an hour with no operation and deep sleep. Android OS is (the one with no sub items) consumes 18% of battery while cell standby only 3%...

4% an hour with no deep sleep = something's holding a wakelock

I came from Cynogen and was also noticing a fast drop in battery life. Things got much better after killing the battery life twice.
-> So far after 2 100% to 0% drains (Calibrating), the battery life has changed for the better.
-> I use wifi when I can. Set sleep policy to off when screen is off, in Spare Parts. I also have frozen half of my OS with Titanium Backup Pro, but I had bad battery even with this. CPU spy says Deep Sleep is working fine. I sync data manually.
My running services are:
Settings (1 Proc)
Task Manager (1 Proc 1 Serv)
Device Management (1 Proc 1 Serv)
Google Services (1 Proc 1 Serv)
Smart Keyboard (1 Proc 1 Serv)
-> Manual Screen Brightness. Using the Status bar sliding finger method if I need brighter.
-> SetCPU conservative seems to work great with Entropy

I change roms like crazy, but will be sticking with UnNamed unless something magical comes out.

Sorry Entropy, it's with Deep Sleep. I made no operation, not even lit up the screen and info shows it does go to deep sleep. Still drains battery.

Placebo effect - our fuel gauge chip requires no calibration, and in fact, cannot have any calibration method applied to it other than pulling the battery for a few minutes.

What's the deep sleep percentage? Check my Known Drainers thread.

[Q] Sleep mode battery discharge rate on different ROMs?

Let's collect some statistics regarding battery discharge rate when tablet suppose to be asleep, like overnight.
I'll start:
ROM - TnT lite 4.2, WiFi On, BT Off, in 10 hours 14% charge drop - 1.4% per hour.
with WiFi Off - around 1% per hour.
I was killing all apps on background before going asleep but this does not affect discharge rate too much, maybe 0.2% and as well might be just measuring error.
What is your tablet's discharge rate?
vegan 5.1.1 clean install, no additional kernel/OC tweaks
lost 30% over 6.5hr of sleep. battery usage shows very little idle time and alot of "android system". i wonder if that means something stayed awake and kept the tab from sleeping or what. o, and wifi was on and awake the whole time too
anyway to put this thing to sleep and last a few days like my HTC mytouch3g when i put it into airplane mode? that phone would drop to the lowest clock speed and sleep with very little battery drain

Why not just power it all the way off? Deep sleep is essentially Off anyway, minus the bootup time.
Cold start is about 50 seconds. When starting from standby - almost instant.
It would be nice if our GTablet can go into standby and don't lose charge with that rate.

Nice, but impossible. Just plug it in overnight. If you want it "always on" you can expect about 16 hours of standby with 4-6 hours of use mixed in. I'm so used to daily charging it doesn't even bother me anymore. Just really happy this thing goes all day on wifi without deep sleep... good enough.
Well, I am inclined to think that this is a software problem (Android OS). Xoom with HC does ok when in sleep mode. Someone say 3%-4% overnight.

Only way it would do that is deep sleep. As in, nearly off - everything powered down except ram, CPU halted.
That's essentially the same as putting your laptop to sleep, vs power down.
The GTab's deep sleep sucks. Not sure what's wrong with it, but it's below the level of android. So it could be a firmware issue. I'm happy with the 2-3% per hour drain when "on" but screen off, connected to wifi, able to generate alerts and alarms.
So, my interest was piqued
I use pershoot's UV/OC kernel, keep wifi on all the time, and use softlocker to make sure my gtab *never* deep sleeps. This is on Vegantab-ginger.
I installed batterymonitor widget, and am collecting data.
First interesting tidbit, my "screen off, but wifi on/not really asleep" power drain is 125mA
Given the 3650mAH rating of the battery, that gives me 29.2 hours total standby time in this state.
Working backwards, that's a drain of just under 3% per hour.
You're actually seeing MUCH WORSE than that, at 4.6% per hour (30% over 6.5 hours) so I agree with you, your software is doing something very bad. You can get nearly 50% better battery life by using gingerbread, pershoot's kernel, and keeping it from going into deep sleep

Any more details? Number of hours on standby? ROM version? Was it deep sleeping (wifi off, clock/time not updated until a few seconds after power on?)
Assuming 8 hours or so sleeping, this is much closer to the expected 1.125%/hour discharge rate for "deep" sleep, or about 90 hours total on deep sleep standby.

if that was indeed true (that you manage to get your tab to sleep for 8 hrs and only losing 10%) then i want whatever you got. I want my tab to be able to sleep for 3-4 days, even if it mean having to settle for JUST 1.0 Ghz
The lowest I've seen so far in batterymonitor widget is ~108ma draw (screen off, 214mhz clock, wifi off)... if the thing goes into "deep sleep" then batterymonitor (and everything else) stops dead, since the cpu is halted - you'd need to poke it inside to see what the load is when deep sleeping.
108mA gets you to 33 hours. To get to 72 hours you need to get the load down to about 50mA. That's the budget to keep the ram chips powered, and the on/off buttons
Battery drain with ext3 partition and S2E?
Is there a perfect way to check what's draining your battery? Recently I've been noticing that my battery consumes almost 20% of charge during night, whereas it used to only eat about 5% in my previous installation of CM7.
First install of CM 7.0.3 - Good battery life, night drain is only about 5-8%.
Second install of CM 7.0.3 - Worse battery life, night drain is about 25%.
The main difference in the second install in that I have made an ext3 partition in the sd card and I am using S2E and have moved some apps to the sd card. Will this consume more battery?
Had a look at the battery history in spare parts, and I see that the partial wake usage by Maps and K9 mail topped the list. Uninstalled both to see it they were the issue. I have Juice defender plus where I have configured data off hours from 12:30 am to 6 am. Still it drinks battery. Any thoughts?

[Q] Battery life normal?

Hi guys,
I'm using GingerMod v0.3 with the default kernel (ninphetamine 2.1.3).
My battery was at 100% when i went to sleep. After about 8 hours when i woke up, it dropped to 92%. Is that normal?
I have turned off automatic sync as well as gps. Even "Back up my data" and "Automatic restore" was off. Display was at a minimum 3%. Most of the battery % was used up by Android OS.
given the percentage of the draining 8% over 8 hours i quess is pretty good. I quess different rom + kernel produce different effects. Yours is considered ok.
ya the drain is quite normal

1% an hour during sleep mode is considered good? i had the impression that it would only drop 3-4% during sleep.

More than good I'd say. And you never can have a constant rate, one night it will be 3-4%, other night it will be 9-10%, depends on the processes running at that period. If you have Better Battery Stats installed then you will be able to see what had cost that extra drainage under Partial Wakelocks section.
I normally have 3-4% drain in an overnight period of 8-9 hours, but yesterday it was 15%. Then I saw it was Camera360 Ultimate which was running and searching for GPS!
Regards.
That's about similar to what i get on standby with data enabled so yeah good battery there/
Thats good ? Mine drops 1 percent overnight (+-10 hours) with original battery Or stays at 100 until morning when I wake up with 2000mah bat... Data and wifi turned off.
But I presume thats just me being battery friendly user
I tried better battery stats and it seems the Email app is consuming the most resources during sleep. hmm...

Battery Drain <== Core Apps

Hmm...well, this is the second time that this has happened in the 2.5 weeks that I've owned this phone. I'm currently running unNamed ROM 1.2.0 and noticed that my battery is draining quicker than usual (8%-10% drain per hour on IDLE).
Usually, my battery drain is between 1% - 2% per hour on unNamed. What I've noticed in both the instances where my battery drains rapidly is that I end up seeing 'Core Apps' (white envelope with android icon in the middle) under the Battery Usage. From what I can recall about this icon, it's the icon for the launcher. CPUSpy shows my phone at 78% deep sleep (the phone's usually around 93% - 95% deep sleep when in idle).
The first time this happened, I was away from home on business for 1 night and ended up having to power my phone off when it got down to 11%. Got home later that day and recharged my battery while the phone was off and after the phone was 100% charged, it lasted 38 hours with 7% left before I powered off and recharged. Again, the battery with light usage lasted 30 hours with 30% left.
Today, after charging (while off - seems to charge better this way) I was surprised to see that my battery was draining at ~10% per hour and I saw that 'Core Apps' was listed under Battery Usage again.
Fortunately, I am not away on business this time (yeah, my spare charger is on the way) so I can recharge teh phone at home. Is the only way to "reset" the phone's battery usage history by pulling the battery or charging the phone?
Hopefully, one of the devs can answer or provide a fix/workaround for the 'Core Apps' drain? (BTW, I leave my WiFi on all the time and my phone still lasts anywhere between 28 hours to 40 hours...just wondering why I have these sporadic glitches when the battery doesn't seem to last long.)
From my experience... this will be very hard to fix. Usually appear ramdomly, and disappear randomly.

Yeah...the 1st time it happened, I was wondering "WTF is 'Core Apps'?"
Now that I've seen this the 2nd time, I'm stumped by it since you're right...it doesn't happen often and doesn't seem to be reproducible by any consistent method.
Hard to do a battery pull with this Neo Hybrid case (case is a PITA to remove) and I don't have my 2ndary charger yet...
Rebooting the phone does nothing since the battery history remains and even powering off for an hour and then powering the phone back on still doesn't clear out the battery history so the drain continues!
Oh well...it is what it is then I guess...I was hoping that someone smarter than I could find a way to cure this. (BetterBatteryStats doesn't show this as a wakelock (partial or full)...CPUSpy just that my deep sleep state is in the mid to upper 70% which isn't the norm.
Oh well, hopefully, this doesn't happen too often.

But a few have reported their phone doesn't behave right in reporting battery percentages after wiping battery stats.
Doesn't mean you can't. But no one has proven it helps.

I haven't had any issues that can't be directly linked to something else (like random reboots).
If all you want to do is reset your battery useage screen to zero it definitely does that. The point isn't to help anything, just to reset the screen to zero without having to wait for the phone to charge all the way.
In that case not a bad idea if you see it show up. If it's as bad of a battery drainer as it seems and still running, it should show up again pretty quick after you clear battery stats.
It'd be useful in reading the logs to know that at a certain time it was for sure running.

Dunno, it's just odd...recharged my phone last night and now I'm back to 1%-2% battery drain on idle and the phone's going back into deep sleep at 93% and I haven't touched any of my settings. I just let the phone dip to 19% and powered off and put it on the charger for ~4 hours (I know, I could've pulled it sooner since it wasn't at 0% but honestly, I forgot.)
It's just the weirdest thing...whenever Core Apps appears as the envelope w/Android icon it seems to be persistent and stays in the battery usage. However, there have been times when the Core Apps appears as teh same icon as 'Contacts' and will disappear on it's own after a while. <-- This seems to be okay as the battery drain remains minimal.
I'll have to check out Entropy's battery drain thread later to see if I can gain any insights. (Haven't ever flashed any of Entropy's kernels as standalones -- I've just been flashing unNamed ROM so I know the kernels are stable builds and not the experimentals.)

Battery issues

Since Jelly Bean release ive noticed that the battery life hasnt really improved for me. Actually its gone to worse. Normally i dont use my tablet very active, so there were cases when i had 10 days between charges. No, even without using, the battery holds maximum of 4 days.
I dont have wifi lock, i have disabled backup, only have synchronisation of gmail and drive, but i had those on before aswell.
What i see in the battery graph is that even when wifi and display are off, something still wakes the tablet every 10-15 mins or so and drains the battery. In the stats it says that the "Standby mode" has the most usage...
Could anyone help me with some app to diagnose that problem or share similar expiriences..

I resolved my battery problems using Wakelock Detect:
https://play.google.com/store/apps/details?id=com.uzumapps.wakelockdetector&hl=en
You might want to give it a try. Turned out that some badly written application was holding wake lock on my XTS and thus jeopardizing the battery life. I also use Battery Monitor Widget:
https://play.google.com/store/apps/details?id=ccc71.bmw
It won't tell you source of the problems but it will tell you how much battery is drained when your device was sleeping.

Btw. for WLD enable advanced mode from settings. It was system process which was holding wake lock and by default, WLD does not show system processes at all (!!!).
batery life always been awfull on XTS it was't bad but it could last easy 3 day's on single charge if sony optimise it.
my nexus 7 i can easy achieve 2 day's on single charge maybe 3 day's and it only has like 4200 mah batery with wifi actualy staying on always.
now in standby only drains like 1% batery per 3 hours
XTS always drained 2% per hour for me in standby

Wtf, that would drain the battery in two days?! Definetly some program has wake loke on your device. I havent done any measurements, but I think I've left my device on my table for week and read E-mails every now and then without any charge and it still has some juice left!

Actually on ICS i had one time when i had 18 days of standby and i used the tablet occasionally
Update on thread:
I found out Google Maps was waking the sysem every 10-15 minutes to look for a location, even tho GPS and Wifi were off. I disabled Latitude and automatic locking on location and also disabled every location option possible (use wifi to lock location etc.) and now its better..

WTF... Android system consuming 90% overnight in deep sleep

I did a complete charge last night before I hit the sack. Battery was around 96%, today morning 80%!
I flashed stock ROM using TWRP, on first charge cycle battery is fine - just 1% overnight drain with 8 hrs SOT. On second charge cycle this issue hits me everytime.
All my radios are usually off (WiFi, NFC, Bluetooth, Data).
Android system sucks my battery during sleep and it was at 90% consumption when I woke up (See screen shot #1).
My phone seems to be in deep sleep a good portion of that time (See WLD statistics #1).
Also attached screen shots from WLD for Summary, Kernal / Partial wakelocks & Alarms.
Device is rooted.
Going crazy trying to find out what's happening.
I have tried 3 different ROM's which have great battery life as reported by other users here for my mobile (Mate 8). But I always end up with the same battery drain issue on second charge cycle after flashing a ROM.
.
Bump! Anyone?
Any experts that could help out here?
I have searched a lot but no solid solution.
