[Q] LG Optimus Black Battery Life?

Hi There OB Users,
Just curious about your battery life.
Please post how long your battery can last.
What ROM and apps you using.
Mine can last roughly 20 hours on low usage (3G ON)
With Wifi ON, it's about 10 hours.
I'm using an app called "2X Battery" (can be found on market)
I'm running NOVA 4.5 ROM
Really appreciate it.

NOVA 4.5
Last three days I didn't use that much my phone so I could test how long does it go without charging.
Calling ~3min
WiFi - 5min
Camera - 10 photos
Winamp - 2h
Display was on about 1.5h
Other apps (no games) that don't use internet - 20min
At 5% I had to charge it for next day. So 95% = 2 days 18 hours. It would be 3 days if I didn't look what time is that often.
But for "normal" every day use, it's 1.5 days. I don't use internet because it's slow in my city (and it's optional for my plan). And at this moment I don't have WiFi router at home (I broke antenna).

Hey there.
here: NOVA v4.5
I use my phone a lot, like 2 hours of 3G network (lot of whatsapp, and quick web search). 3G aways ON
1 hour of calling
3 hours of music
The battery life is about 10 hours.
It would be great if i have at least a day, using it like i do.

Maybe undervolting?

hi u all!
i'm using cm7 for few days but its feel like my battery wasted so
last night i'm install 20b rooted rom then i install setcpu and advanced taskiller, i set them to battery save mode (its like close all app when screen of for taskkiller, and for set cpu, make my cpu %30 use when screen off) and i charced my phone it was %99 before the sleep. when i woke up i look at my phone and battery percent was %67, basicly i freak out!!! I JUST SLEEP and something use my battery %32
so, i delete setcpu and stop all activity of taskiller, but nothing change, battery keep going down :/
sorry for my terrible english

Check if you have apps which refreshes between intervals (or even push notifications) and avoid them.. the best solution is to disable Wi-fi and, if you are not a demanding person by others, switch to airplane mode while you sleep!
EDIT: If it doesn't work, just go to recovery and clear dalvik cache

Unfortunately, along with many of the downsides of CyanogenMOD, battery life is an absolute joke. I think you'd be lucky to get over 24h of usage on that ROM. I have no idea why, but it seems that it sucks the life from your phone WAY too quickly.
For those having battery life issues, I'm on Zeus 6.11o and i've increased my battery life by just:
Using a good governor (smartassv2) to control CPU usage when screen off.
Recharging from dead to 100% seems to increase battery life.
And after using playerpro for an hour, surfing the net, using NBA.tv, 3G always on, an hour or so of Kairosoft gaming and i'm currently at 73%.
So life's good under the hood.

wait for ics. im using L7 right now, the battery life is way better than gingerbread.

New ICS UK official release battery drain

Manually upgraded over stock non rootable CarPhone Warehouse GB rom using PC Odin.
Im getting very bad batrery drain. On the stock GB rom my phone would easily last two days with moderate use. Now with the ICS rom its draining pretty fast. I took it off the charger approximately 1.5 hours ago and with little to no use Im already at 90%. Same stock settings and same apps. Only difference is I am now using Apex Launcher.
I noticed wifi constantly on even during deep sleep but i have now configured it to only be on while plugged in.
Ive pulled he battery out for a few minutes and that hasnt helped. One last thing im going to try is revert back to GB and then wipe, clear cache and upgrade again...
Any advice/help would be appreciated..

I´ve had the same wifi problem, german stock ICS though, weird enought it seems to happen just with my home´s router. I´ve checked in other places and all was fine. A couple of users here changed their routers seemed to solve the issue. See if this is of any help....
Cheers,

My note seems fine, have you tried the fix below.

Betterbatterystats for whats keeping phone awake
Android sucks in providing the info you really need up front.

Yeah, i updated to the lpy ROM when it was released and found the lack of deep sleep issue causing a problem. The above fix sorted it and I've had no problems since, performance has been noticeably better and battery life has been just as good, if not slightly better, than under ginger bread

Takes longer to analyse bro.
In those 24 min abnormal battery drain?
Best to check battery percentages.
Next to these two apps you can check badassmonitor or equavalent, they have also good measuring for actual battery usage per app.
Analysing sucks thought, totally not user friendly.
Sent from my GT-N7000 using Tapatalk 2

I could be wrong but it seems as if my wifi is still constantly active...battery drain is pretty bad...i think im going to revert back to GB, perform a full wipe and cache cleane and re install...

I did an "factory data reset" before and straight after i upgraded to the official UK ICS.
I did read if you use the alarm clock, it keeps your phone awake, even after you disable it, other apps most likely do the same.
Below is a picture over night, I always manually enable/disable wifi/bluetooth/gps as have yet to find an app that works correctly.
John.

Yeah tipically you would be looking for the following:
If your device goes into deepsleep at all. (on battery that is)
You can check this with cpu spy.
If it doesnt check the kernel wakeloks (high level) and the partial wakeloks (zoomed into detail level, best level for troubleshooting).
Anything there that runs often and long is probably causing the deepsleep insomnia. I wish Android would be better in able to determine what really influences your phones battery.
Next to this, some apps you can change synch settings (within apps itself, e.g. facebook etc) Thats just a typical change. every sync uses energy, and wakes up device.
Another possible check is the power on of with airplane mode.
Another tip is unchecking the sounds when touching touchscreen (a bug from the old days of android, and they never fixed) this is a major wakelock causer and by default turned on.
I usually get 4~5 hours nonstop onscreen time after tweaking it (without setting to much stuff of, otherwise I could have gotten a normal phone lmao)

after factory reset and data wipe on your galaxy note please calibrate the battery both ways...horizontal and gyroscope.
This will definitely help your phone better monitor the battery and bring it to normal status..

I tried out the steps mentioned in above link and I think its working for me.
After upgrading my note to UK ICS release the battery is drainig like anything.
Its like 1% every minute .
After applying steps mentioned in the url its not draining that much. MAy after some more recharge cycles it will be more stable.

[Q] V20A Battery.

I'm kind of worried of my battery life..
Last night was my first dissapointment, I left my phone untouched for the whole night (8-9 hours) and something just sucked away about 30% of my battery. Not sure if it just didn't go in Deep Sleep or bloatware leeches that much energy off it.
Within 4 hours of which not even 1 hour of Data usage + WhatsApp/Facebook another 30% just went away.
My battery was not this bad on ICS, specially if I left it during the night, I'd see max 5% drained.
Is this normal for now? Untill I go trought a bit of full rechanrging cycles? (From >5% till 100%)
Or it would be better if sometime I root it and remove some of the bloatware and convert system apps to user ones? (Like Maps,)

I also also less battery life. Is I have the double of the consumption in comparison With ICS . It dont have 1 day of battery life (18h), and I don't play. It's unsustainable...
Sent from my LG-P880 using xda app-developers app

I noticed that last night (after upgrading) I lost about 10% battery over seven hours, usually I'd only lose 4 or 5%. A little worrying. Google Now is turned off etc, just data, 3G and sync was enabled (just like I used to have with ICS).
I've just backed up my phone and might try a factory reset and restore to see if that fixes it.
I have noticed that if I open CPU Spy and reset the timers, then lock my phone and wait a minute, it is spending a fair bit of time with the CPU at 475mhz. I used to get deep sleep for 90+ % of the time, with 4.1 it seems to deep sleep about 60% of the time.
I'm gonna see if I can figure out what's waking it.
Did either of you do a factory reset after updating?
EDIT: Did a factory reset, installed BBS and CPU Spy, and a quick test found it in deep sleep 87% of the time. Currently restoring using the LG backup app, we'll see if that sorts it or whether there's something else going on here. Will report back with my findings.
EDIT: Ok, LG's restore tool just finished restoring the backup. It worked fine, aside from warning me about possible problems from a 'cross version restore', even though I made the restore with the same firmware version. As a side note, that LG restore tool is SLOOOW! I have a few big games but it would have been faster to set everything up manually, haha. Probably 2-3 hours it took to restore, though it was hassle-free.
Phone seems to be sleeping much better now... a few tests with CPU spy show about 92% of the time spent in deep sleep, which is about what I'd get on ICS. It's early days but if you guys want to give it a shot, it's shown some promise.

I just checked my phone battery stats and saw this:
Where you see the huge battery drain that's where I was downloading and then testing NFS (had better results than on ICS btw)
Battery was on 40% so I closed everything, even WiFi and went to sleep (7-8 hours)
If you see the stats it did went into Deep Sleep in the beginning but something woke it up and kept draining the battery.

I wish they could build a CM10 ROM with OptimusUI... I really like the visuals.

I cant say I am pleased with battery life on JB. I only had it for one day but it drains faster than ICS. Through the night,in about 10 hours,no wifi,no sync,no 3g,fast rebooted it drained 15%!On ICS,in that period of time, it would drain 3-4% max...On CPU Spy, "deep sleep" is only 33% so something is draining the batt..Anyone else with this probl?

Another update... I started having my phone only deep sleep for about 60% of the time again... and I think I have figured out why. Go to Google Maps, go into settings and check that "Report from this device" is unticked! Mine had somehow been enabled and I am fairly sure it was responsible for my deep sleep issue.

I was experiencing the same high drain overnight until I stumbled upon a thread on here which suggested deleting the maps apk and odex file from the system/app folder using a root explorer. you can then reinstall it from the market. I also did the same with chrome.
before I checked with BBS and maps location services were waking the system up constantly, but after doing the above things are much much better.
you can also try disabling MLT in the hidden menu 3845#*880# as there's a thread in general suggesting this logging app could be eating into battery life/ performance.

Is it normal that the battery drain overnight is over 10% in 7-8h ?

My battery life is very poor..Over the night it drained 30%!!! And I killed all the apps, wifi, 3G everything... Through CPU Spy I can see that my phone doesnt go in deep sleep(only 13%) and it is working on 51MHz for 76% of time!! And I`m not even touching it,the screen is off...Whats up with that?How can I fix it?
P.S. I disabled Google Maps because I heard that they consume a lot of battery in the background..

Find your wakelock, find out whats causing it, then fix it ;p

Either use BetterBatteryStats (which is available free for XDA members, search the forum), or Wakelock Detector. To use either of them, plug in your phone and let it charge up. Open BBS, it will create a reference state. Then unplug your phone and let it sit overnight. In the morning open either application and it will show all the wakelocks (times at which the processor was prevented from deep sleeping). Look at what's keeping the phone awake, and remove/disable it.

[Q] Mobile Network Signal (Cell Standby) DRAIN

Hello guys I'm a newbie here so please do explain to me some of the stuff if you need to
so recently (about 2 weeks ago) I used this guide to root my Incredible S and did everything except the Blackrose part
and since then
I've noticed that my phone has drained its battery a lot quicker than usual
I lost 11% of battery when I woke up, fully charging it the night before
I usually do not use it much, only a call every 2 days or so, and I do not have internet connection
so I cannot understand how I have to charge it every day now, when it used to last 4 days (on Sense)
here's a pic from betterybatterystats
thanks everyone
------- 4/10 edit
ok
back to stock rom
it has the SAME problem
"No data connection" and "No or Unknown Signal" on Betterbatterystats
with steep drops in battery whenever there is "Mobile network signal"
and next to no drop whatsoever when there isn't
PLEASE HELP ><
new attachments down there with stock rom
tell me if you need a translation
THANKS

Battery drain has already been discussed much in the CM10.1 thread. Its been discussed in practically every AOSP thread really.

I know and I've tried to look around for answers for quite a few days
but for most people
it's either the same as Sense or something else (too many apps, not charging fully...)
and for those with similar conditions
I can't find solutions for
and the problem got worse today
in the 7 hours I slept yesterday
the battery drained from more than 50% to nothing
so the alarm didn't ring because it shut itself off

The standard charging time isnt what it says on the box or anything. It should be roughly 6 hours from 0% to 100% and thats providing you plug it into an AC outlet. I would suggest trying an app called Greenify. It hibernates certain apps/ services that may not be in use thus saving battery. I would also regularly check the Running Apps in settings and clear out anything unecessary.

I don't have a charging problem
it's a drainage problem
and about Greenify
I already installed that when I looked over the battery saving guide (which didn't help)
I literally have 5 apps in the Running Apps section
the part I don't get is
why does Cyanogenmod 10.1 use battery so much quicker than Sense
when I have 1/4 the apps I originally did?
it's the "No Data Connection" and "No or Unknown Signal" part really bothers me.
oh and thanks for the time btw

Hmm then this battery drainage is strange. Try making a full backup in recovery. Then clean flash the ROM again. If the problem still persists, then I have absolutely no idea whats wrong lol

I tried that...
on Sunday afternoon I reflashed it
my exact steps:
1. ClockworkMod backup
2. Install from zip
3. Advanced restore - data (I restored the whole thing too once before that, but thought that just restoring the data might actually change something)
and that's when it went from 50% to 0 overnight
not looking too good -.-

oh well then
thanks for the help anyways
I'll just keep waiting
might want to go back to Sense though...
and more pics from BetterBatteryStats
just in case anyone knows what they mean

Drained 56% of my battery while I was asleep yesterday (for about 7 hours)
only 6% in the time I was at school, because of Airplane mode (I even listened to music and played a little Doodle Jump)
but I obviously want a phone to CALL PEOPLE
so I'm reverting to stock Rom

OK
so that didn't work out
I edited the main article
hope someone can help!!
meanwhile I'll look for more articles online since I know it's not (really) CM's problem anymore
thanks

Ensure to charge your mobile fully and after a NORMAL usage (calls, WiFi, Mobile Data on).
Just share the dump file from betterbatterystats. It would help to analyse better.
Edit:
Could notice you are using some widgets in the home screen. Usually widgets with high refresh rate drains your battery.
2. Facebook app is causing the partial wakelock. Even when the screen is off, the app is using your CPU. Try to disable autosync if it's enabled
3. Audio_out3 wakelock is due to phone vibrator is enabled. May be during call or keyboard haptic feature.
Power manager service wakelock is common and its in good level.
Try to check your CPU freq n governor.
And adjust accordingly. One more, Li-on battery should not be charged fully. Just charge till 85-90%. The battery will drain little lower compared to fully charged device. And you need to charge your device only when battery is low. Frequent charging n discharging will affect the battery life. Consistent Charge and discharge cycle is encouraged.
Try to share your fresh dump here or in batter battery status thread. There are many folks to help you with.

Thanks for the detailed reply sir
My widgets (aka weather & tasks) only refresh manually, and nothing is on Autosync (in the auto sync menu, anyways)
originally had only vibration for calls, turned that off too now
and what is "CPU freq n governor"?
didn't know that about the batteries
I'll do that next time
and I just reinstalled betterbatterystats, so I'll post the Dump File after a few hours
Thanks again!!

I mean CPU frequency steps and CPU governor. It's a kernel thing. Just search xda, you will lot of info regarding that.
Sure, post your dump with normal usage.

[Q] Help with huge battery drain on usage [TRIED EVERYTHING]

Hello guys, sorry for my bad english, but I'm not American. Well, my question is:
I bought from a guy a Galaxy S I900b, Brazilian model with digital TV. Came with stock 2.3. As I had already read enough before, upgraded to JWB Saurom with semaphore kernel, which I think is the default for this rom. Well, the phone had very poor battery life, evn on idle. Then upgraded to 10.2 CM. I saw that had some wakelocks, and with BBS and the help here, I used the Scan Media Root and my problems are gone in iddle. So, my phone goes into deep sleep and today during my sleep, only lost 3% battery, 3% battery drain on idle during about 5-6 hours it very good to me. But during use, it ends up very fast, and with GSAM and standard monitor of the android, I saw that after the screen, the Android system was what had higher %% battery. So what could it be ? The battery life is ok, checked on info, and its condition is 'good'. I use to Greenify, and close almost every game\app, so running is just grenify and ram manager pro.
So the prob just could be a app or the 'android system' ? Or even hardware ?
I dont have much time now, so any info or screenshot you want, I can provide later
Thanks

What about your connections? Do you have 3G/wifi enabled at all times?

calibrate....maybe useless, but u can try....but somehow, try bigger mAh battery, maybe.....n maybe .... it will help.
juz charge it with screen turn on till it full, n waste it to 0% till it shut down, turn it on n charge it with screen on till it full again, u ll be fine
if problem occur again, keep an eye for sneaky app that run at background (email...exchange etc) n juz delete some sys app that u dont use using titanium.
if it still occur again, wait for arc reactor battery....

So buddy I've disabled 3G, just 2G, I barely make a call, just wifi. But dont matter what, if is just passing by the menus or using opera mini, using it drain battery a lot,

I've deleted the batterystats.bin and used until 0%, so charged while off, but nothing :C
It's true that the battery needs to 'learn' ? Like, a few charges and discharges and could estabilize ?
I'll take a few screenshots right now

Callibration of you battery eg: Wipe battery stats is onluy helpfull when you get weird battery stats.
If you are on any CyanogenMod ROM you have to get used to the higher ammount of battery use by the phone. The application Greenify can help a lot by hibernating the huge battery suckers like facebook and google maps.
Some tips:
- use 2G instead of 3G
- Turn WIFI off when you're outside the house or leaving for some time
- Turn GPS/Bluetooth on only when you're about to use it
- Dont use taskkillers (they are used to free up ram but killing apps makes android restarts them and this consumes extra juice)
- Put brightness on Auto
- Use a dark theme and background/lockscreenwallpaper
- Dont recharge your phone when below 5% this can damage the battery
- A new battery needs to "Get used to" the life of being a battery xD After a few recharging cycles it will work like normal

Here some screenshots, if need more, just ask
Note: Was with 14%batt, rebooted and drops to 11-10%

i am using greenify on almost everything.
used to use ram manager, but now i've disable it.
brightness is on low
I really dunno what 2 do ... almost 1 week with it and this insane drain, everyone says that plays or browser on wifi and get almost 10 hours... my dream this happen to me lol
Remember that this is just on use, on idle it use virtually nothing, like I said, almost 3% on sleep, but is just I start use with app or browser and its gone

Screens are from a too short period of useage. Use it from fully charged, and make some new screenies This can help futher

Well i got problems with my battery too so im planning to buy a new one because this one cant even handle 3-4 hours when im doing something like playing games,or listening music...Just buy new battery with more mAh and dont get bother with this :laugh:

if calibrate doesnt work, hardware faulty, change ur battery mate.

About 2 hours later that I fully charged, here are some ss
Just used whatsapp and opera in this time
I was thinking in change my kernel, currently I'm using semaphore 3.0 with CM10.2, is Latrop or Mackay better in battery life ?
I think its my last shot ... I'll provide a new battery next week, but i've heard some people with batt probs that even with new batt the problem persists :crying:

It looks like wifi and 3G have been kept on for most/all of the time. Turning those off while you're not using them may significantly increase battery life.
Also, related to kernels, personally I've found Mackay to be a bit better in terms of battery.
Also it looks like your screen's pretty bright if 61% of the battery usage is because of it. So if you don't need it so bright turning the brightness down may help.
Start by doing those, and see how your battery life fares first- if not much changes, then it may help getting a bettery battery/changing rom even.

So, like i said, in this 2 hours after charge, i've used opera mini with wifi, I dont use 3g. Right now the battery is less than 10%... it's strange since have people telling that can use almost 5 hours wifi and the battery is > 50%
And the brightness is at lowest bright :\
The problem could be some corrupted file ? I have the options:
- format EVERYTHING, and dont use titanium backup, since somthing can be corrupted.
- change my kernel to Mackay
- change my room back to SAUROM 2.3.6 adn semaphore kernel
I'm very sad cuz I have a very old Nokia E5 that can be on with wifi almost or more than 10hours ... and this phone can barely hold 5hour
What u suggest me to do ?

How long have you been using the rom? Roms take time to calibrate the battery and this is through charge/discharge cycles.
Alternatively, go into Performance settings and change the profile to powersave/conservative (it differs from rom to rom). Lock the min CPU frequency to 200mHz- apparently this helps.
Again, this would change depending on your kernel.
And if you have a three year old battery like mine, best not to expect miracles...

Using bout 2 days ... but i didnt knew about ' calibrate '. Good to know that
Now i've formated everything and will put a stock 2.3 and see in a couple of days the perfomance ... if gets better, I put the saurom 2.3.6 and be with it, cuz 2.3.6 on brazilian model allow to use digital tv, and 2.3 everyone says is economic.
I'll get this updated if my situation changes, if not, will buy a new battery
Thanks for all your help
Note: How long your batt last ? With high\low usage
