[Q] How do I tell what's eating my Battery with BBS? - Galaxy Note II Q&A, Help & Troubleshooting

I have just got Better Battery Stats.
I heard good things about it, but I'm clueless at it when finding out the culprits draining my battery.
On a full charge before I sleep and unplugging it, my battery drains about 10%.
How do I look at BBS to determine which programs are draining it so severely?

See under Partial wakelocks section. And if you don't see anything suspicious there see under Kernel wakelocks.

The problem is probably Media Server, just check for it.

OP, did you find out what was draining your battery?

Galaxy Nexus Battery Usage - Android OS

Hi
Not all the time but every so often my battery drains really quickly. It might be at 80% at night and at 20% the next morning and if I look at the battery usage stats the OS has used the majority of the OS. If I restart the phone it will usually be ok again.
Is there anyway of finding out what part of the OS is causing the issue or how can I stop it? Its not an issue if I am able to charge the device as soon as I relaise but sometimes I have to go out and then have a practically dead phone for the day. This can also happen at other times as well but I usually just check it periodically in case the OS is using the battery a lot.
Thanks
Brian
If you have CWM - charge the phone to 100%, then wipe the battery stats. Oddly enough, it did the trick for me. I've had about 20-25% overnight drain before. Now <5%.
Also check for apps that are waking your phone with BetterBatteryStats (you need to check for partial wakelocks). Maybe some app is not draining, but just wake your phone too often so it can't deep sleep.
if your android rooted,try "One Power Guard" download from onexuan.com,It can help you extend battery life .

I can 100% guarantee that wiping battery stats in CWM had absolutely nothing to do with it. It is literally impossible, as batterystats.bin, which is the file being wiped, has zero bearing on the battery fuel gauge. Wiping battery stats has the exact same effect as, say for instance, charging the phone hanging upside down only on even-numbered dates. It also bears mentioning that the file is wiped by Android anyways when the phone is unplugged after charging,making the misguided advice to wipe it even more pointless.
Any "benefit" imagined by those who advocate wiping battery stats is a textbook example of the logical fallacy known as post hoc ergo propter hoc.

/\ post above is 100% correct. Wiping your battery stats will have absolutely no effect. It is not needed AT ALL.

Battery drain "rx_wake"?

Just flash ViperX over IceColdJelly and have been experiencing battery drain. So I installed betterbatterystats to see whats been draining and the two biggest battery drains were rx_wake and baseband_xmm_power.
Can anyone interpret what they mean?? And how do I go about fixing them so that they don't drain the battery.
This was the result after I had charged battery to 100% and left it for about 20-30 mins
Thanks in advance!

Batterylife

Hi!
I installed blackout ICS incredible in my DHD. Everything went well but I wanted to calibrate my battery.
So I downloaded Battery Calibration by NeMa from Google play. Before calibration my batterylife was about 12-24h depending on my use.
Now after the calibration my batterylife is about 5h!! And the same usage as I have always had, couple of calls, net surfing and maybe a little of Angry Birds and spotify.
Did I do something wrong or is my battery dead? My DHD is about 2 years old.
According to Google calibrating your battery (erasing your battery stats) doesn't actually do anything, so it shouldn't have made your battery life shorter. You could install BetterBatteryStats from a thread here on XDA to see if something else is eating your battery. Look at alarms and wakelocks.
Ok, thanks. I installed the BBS and I'll tell the alarms and wakelocks here if I don't find anything funny about them...
bananagranola is right.

calibrating your battery basically tells your OS how much batter it has or doesn't have. IF you flash a rom at less than 100% battery, then the max amount of battery your OS thinks it has might be different from how much your phone actually has. Sometimes this can affect battery life.
The other thing is, did you calibrate at 100%, then unplug immediately? If not, that might trick your OS into burning your battery so quickly.
Otherwise, 12hrs to 24 hours is super amazing, I'm a semi heavy user, and I'll only be able to get 12-14 hours of semi serious use (8 hours standby, 2 hours on off usage, some of that at 100% brightness when i'm outside, and lots of music), end of that I have only 32% left. 24 is pretty amazing, I wouldn't be complaining :laugh:
Well when you simply reboot new stats are generated.

Ok, so I have had today the BBS running on the background. I tried one thing in afternoon, I switched of Wifi. Wifi was off about 3h and when I came back to home I switched wifi back to on. I have still 70% battery!! and about 12h without charging.
BBS alarms:
android, wakeups:83 (Is this much?)
com.google.android.gsf, wakeups:56
com.android.settings, wakeups:13
and the rest of them is under 10
BBS Kernel Wakelock:
wlan_rx_wake: 14m18s
PowerManagerService: 10m57s
and rest is under 4mins
BBS Partial Wakelocks:
AudioOut_3: 3min16s
Twitter sync: 1m56s
BBS Other:
Deep Sleep is about 10.5h
Wifi On/running is about 6h
Is there something wrong or is there something that uses too much battery? Could the battery be "damaged" due it's about 2 years old now?
Sorry for stupid questions but I find it very annoying that sometimes battery life is 5h and sometimes it's way more than 12h with same usage.

What you've got looks fine (which makes sense, since you had good battery life this time). Keep BBS installed. If/when battery life starts tanking, take a look at BBS and see if anything else pops up. If you've got more questions then feel free to post again here.
Although you might miss the customizations of the roms, aospX has great and I mean great, battery life.

[Q] kworker, battery drainer or normal?

can't ever recall this as being so prevalent. getting them on AoCP, AoKP, and blukuban (that I've looked at thisfar) both with FF18 and fc22 modems. bad battery life too.
Bump, down from 99 to 82% this AM only 2.5 hours after unplugging from charger. over 1 hour awake with screen off the whole time. Any suggestions other than better battery stats to see what programs / processes are keeping phone awake or CPU usage?

[Q] Typical idle battery drain on your 8.4?

I was curious what kind of idle battery drain people are getting on their tablets/ROMs?
Measuring with Battery monitor Widget Pro, on my 8.4, running stock TW except for Towelroot, I am averaging -150ma.

Since I have an amper cable I can see the current the tablet draws when its plugged in with screen off / idle and fully charged. mine does this
0-0-0-0-0-0-0-0-0-20-0-0-0-0-0-20-0-0-0-0-0-20
so I would say its draws a quick 20 ma every 10 seconds - but since its plugged in it might not be in the deepest sleep setting that it would be when on battery.
anyways I have no problems with it staying at 100% or 99% leaving it off for the whole day unplugged so it has very good power management in my opinion. - just have to keep the wakelock apps in check
I updated from the ng1 build to the latest nk1 build and my idle battery drain is much improved with the exact same setup running. Now down to -40-50 mah.
I have terrible battery drain randomly for no reason and I don't no what is causing the battery to drain so much. I have attached an image is there anyway of seeing what causes this much battery to drain so quick?

You should install better battery stats, available here on XDA, to pinpoint your battery usage.
Looks like there was a really battery draining event that occurred quite suddenly?

I noticed in the screenshot you have might GPS on, there could be an app running in the background abusing GPS or polling it too quickly (look for a blinking / solid white pointer Icon in the top left of the statusbar, this will tell you if something is requesting location).
GPS will drain battery very quickly and should be disabled unless it's needed.
