[Q] P990 problem with battery life

Hello, i have P990 maybe 3 weeks on android 2.3.4.
Yesterday: battery lived for about 8 hours...
and in options-> battery use-> on screen phone have over 70%
What is On screen phone ?
what i can delete it or stop it?
Sry for english, I hope you understand my problem .

I think on screen phone is just the display. To improve battery life try and calibrate it, search for battery calibration on the market at follow the instructions

on screen phone is a program to work with your phone on the pc screen.
If you dont want to do that you don't need it.
You can download advanced task killer from the market and use that to kill that kind of programs (like carkit etc.)
Better is to root your phone and download titanium backup and freeze programs you don't use.
Or download root explorer and use that to renam the programs (in system/app) to .bak (like LGonscreenPhone.apk to LGonscreenphone.bak) and then reboot.
LOOK OUT you don't do that to programs your phone need to boot.
Hope this helps
Greetz, Stefan

Hi there is a general thing to do, beside using task killer which it is giving a nice help, you could check how often your phone it is updating facebook, gmail and other services, this is itinerancy.
The other thing to do it is to diminishing brightness of the screen.
here are some general things to do
either way, you could go and google it ¨android save battery life¨, the first 2 finding will be very good to put in practice.
i hope this is helpful.

moises :cyclops:

Also, you can calibrate the touchpad brightness to increase battery life.
however, best idea is to get a custom rom and optimized kernel!!

Since I have used Custom ROMs my battery live is much better than stock.

Had same problems, but now with cm7 and custom kernel the p990 runs for round about 2 days.

General Battery Usage Discussion

Hello, I'm starting this thread to actually discuss general battery usage patterns/ concerns. I figure this might be helpful for some people if not then..... =P
currently im using stock gb battery monitor to roughly monitor my battery usage, there is a mod to make the reading more accurate but i havent applied it yet...
Also... lets put up screen of the best battery life we've managed to get our phones here heee, would be fun to see =P
--
question is,
1) is it normal for mobile standby and phone idle to be ard 50% ish?
2) is it normal for my phone to stay in awake mode when i turn on the alarm

On Zeus v3n

Nice idea..
I charge my OB every night, and reboot after alarm in the morning. I dunno if it is from alarm or charging but if I don´t reboot the juice is gone in about 8 h. also battery usage app is frozen. I have this issue on every ROM, ( stock 2.3,CM7 from kang to about 60, marvell, zeus test v2.1, nova v8).
If i do the reboot in the morning the phone uses about 50% of the battery during the day (17 h). i use it for a few sms´s and calls, about an hour of websurf (wifi) and some facebook/ Xda usage..

I dunno, if in not mistaken, when you reboot it deletes your old battery stats bin but I'm still trying to understand how resetting a stat could make the battery last longer its what most battery calibration apps claim to do...
For me once a week I manually delete the stats thru cwm and yeah it does make the battery seem more resilient.....
And yeah I got the same again as my photo again, phone stays awake when I turn alarm on.... :/

I did all in my battery, but the maximum is a day and a half!
Depends on the intensity of use.

Deleting batterystats.bin does nothing to callibrate your battery. It just stores info, like a logger. BatteryUsage retrieves the info to display it.

Something is causing a wakelock, what happened to you is not normal. Usually a reboot solves things like that, if it doesnt, then it will either be a rom bug or an app holding the wakelock. Use Better Battery Stats to find whats causing it.

thanks for the app recommendation found that my dialer is causing a portion of my wake lock..... and system too.... hmmmm
ok lets just say my dialer keeping my phone in a wake lock is caused by malware... would a clean install of a rom and manually reinstalling of apps w/o data get rid of the malware?
meanwhile... googling wakelocks =D

Hi, I have some experience with sudden huge battery drains and wakelocks etc. both on stock V20N and Zeus v3.2n. I did not figure out how/why it works but here are some things you can try. I did not have any huge battery drains anymore the last 24h! (on Zeus v3.2n, did not try on V20N stock)
- I have an IMAP email account installed with K9 mail and an ordinary hotmail account with the hotmail app. Both accounts are set on push and in this configuration the hotmail app causes my wifi to never go to sleep, causing increased battery drain. Removing the hotmail app solves the problem.
- automatic update of time and date settings can cause wakelock. Unchecking Settings > Date & time settings > Automatic might solve your problem. I read this somewhere on XDA.
- Use wireless networks to determine location might cause wakelocks as well. Unchecking Settings > Location & Security > Use wireless networks might solve your problem. Read this somewhere on XDA again.
As I said, I did all of this and my wakelock problem is gone for at least 24h! Now I already have 60h on one battery and still 43% left... I cannot remember the threads where I read about this but if needed I can search... Also I did not try yet whether any single thing actually caused my problem. I just killed all of it as I do not miss it I am happy. Keep me updated if you found out which one worked for you
Tip: the BetterBatteryStats app is written by somebody on the XDA forum, you can download the apk for free from some thread in XDA (search is your friend)

I think a day and a half is a good battery lifetime for the OB, if there is no app or something that drains the battery in a hard way.
I can manage to get this with the marvel rom, and my personal user-settings. Also i think every smartphone u can actually get needs to be charged around every 24 hours.

I also want to share my experience. I use the cm7 2.3 gb rom and the battery response is very bad. Battery completely dead in 18 hours. Then i switched to v20n german gb rom. It gives me better battery timing about 28 -30 hours on normal use. The i change the settings of account syncronization of gmail, hotmail, facebook etc to manual. Then there is a big difference in battery drainage. Now my battery consumed in 48 hours on normal use.

On android phones, if yours phone gives u 24 hours backup then it has good battery timing. Further you can increase the timing through the steps and trick mentioned by different peoples in this thread
Sent from my LG-P970 using XDA

Battery should last at least 18 hours on normal usage with 3G and sync with gmail , contacts and calendar. Sometimes you just turn off so many things to just make it home with some battery in it....

battery is mainly kernel related...
we need good kernels that all..

Thank you for the wakelock tips.
It seems that V20o is way better than all the other ROMS concerning battery, without any tweak. Maybe it can be further optimizet with tweaks.
A short comment: it is true that theoretically battery is kernel related issue, but in a real world high battery drain is usually caused by bad apps and other non-kernel related things.

using zeus v5.03 lite.
battery drains so much when the screen off. nearly 1 percent in every 2 minutes.
but it is ok when the screen off

Ok wasn't an sod but a random reboot, and it reset my apn settings twice when that happened

[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.

Battery is terrible?

I have been using my phone on wife since about 7 am. Since then, I have done maybe an hour of browsing on chrome, installed an app or 2, watch a short YouTube video, checked my email once, and played a game for 5 mins. I saw other people's battery stats and it says they have 20 plus hours of talk time? Mine says there is only 3 hours left. Is it possible I have a faulty battery? I'm also using juice defender and power save along with the brightness all the way down. I'm running android revolution hd with elemental kernel. I have the att version. Thanks in advance.

I find that based on my usage habits that I get terrible battery on Android Revolution v12. I always find myself going back to a rooted AT&T Sense build, and I'm able to pull 3 hours of screen-on time with 20% left.
Be sure to use a Wakelock Detector to pinpoint any rogue apps that are keeping your phone awake when it should be sleeping.
Also; be careful with those "Juice Defender"-type apps, Android has come a VERY long way in managing RAM, and resources since 2.2 (Froyo).
Report back with any findings

Don't mean to hijack the the thread but im having a rather peculiar issue 3g and wifi are eating away my battery like a percent for every 2-3 mins that also while only browsing web nothing else in the background can anyone help . Also im on stock rom , no root and s-off
P.S auto sync is off few apps have been disabled like (play store,facebook , google + and google search and few more)

I have about the same hours on stock rooted AT&T 1.26.502.12. Updating to stock rooted 2.24.401.1 has about the same hours, but it's only been about a week and I'm constantly flashing the new ElementalX kernels, so it hasn't settled.

what? or do u mean WiFi

you should use GSAM or wakelock detector to view if something is killing your battery, I have a very VERY good battery life specially since I updated to 2.24 firmware, i guess you don't have root

Check the ss I posted of gsm, and I do have root. Also, what does it say in talk time left in gsm battery monitor when you have full battery?

My battery life was great until i flashed new firmware. i'm on ARHD ROM and it was great on 11.5, with 12 i started using nova launcher and now battery life isn't as good as it was previously. Have you experienced changes with your battery life while using some custom launchers? Or that's rather caused by new firmware/rom/radio/etc?

if i was you I will do the following
-update the **** out of your ONE (firmware and ROM)
but since it would be to laborious, I probably do the following:
1 Factory reset, in android (backup your things becaus it will be erased if you do a factory reset in android, or just dont do it!!!!!!!!) and in recovery (or only in recovery =.=
2 Install a custom rom that is near to a stock rom like ARHD (do it two times with full wipe)
3 with titanium backup remove (after do a backup) the htc bloatware crap that you dont use
4 with titanium backup remove the gapss that you could download from playstore, like youtube, gmail, and specially MAPS
5 GREENIFY all apps that you dont use commonly, you will be able to greenify apps like maps and youtube
6 DONT USE SEEDER OR ENTROPY MODS!!!
7 DONT USE battery saver apps
8 set battery saver option: cpu, vibration, and if you can get use to, mark the data connection option too...
9 Use lagfix app...
10 download Trickster MOD and set you gobernator to MSM-DCVS (this could cause a little lag when you turn on your ONE)
allow to pass one day with you fresh rom, and the following day check how is your battery life
11 if you still have a not soo good battery life, try disabling media storage in apps configuration menu, maybe you have some corrupted media files that dont let media storage to scan all of your media and check if your battery life improve, if so, you should clean your media files, (because let disabled the media storage app have very high side effects)
optional
12 use mods related to a battery life of pimp my rom
13 disable location update from maps, and all location things from configuration (enable when you need them)
14 disable all autosync things that you could do manually, like dunno facebook
15 disable auto update hour and date
+++ disable google now
more optional sh*t
16 when your phone is fully changed in android, turn it off and let it charge until the led change to green, do that one time every two or three days
17 battery stats wipe whit any app of playstore
18 manage your brightness screen manually (its easy and fast in android 4.2.2)
fin...
normally i get 5:30 and 6:00 hours screen on time with a very good use (3g) but one day i get these results
BTW download the app batteryDrain is very good to check how your battery is draining
...And set the option in GSAM that show statistics since last full charge, and dont plug your phone because it could reset the statistics (well if you are reviewing your BLife that could be a problem since stock battery report of sense is almos usless)

[Q] Low battery life

Hi, I have problem with my battery life, I've bought new samsung s3 mini and got it with android 4.1.2 but battery life is pretty low, it can't last for 24 hours, can I do something to extend my battery life ? I text few sms messages, talk about 15 minutes, wifi is almost always on, screen brightness is set to minimum when ever I can do it, check little bit news over opera browser (maybe 15 minutes of use per day), also make few call over viber (about 10 minutes per day).
I've read that update samsung firmware via kies can help improve battery life, what should I do ?
p.s. my phone is not rooted if that is impormant, also I am neewbie
Thanks for help in advance

factory reset from settings fixed my AndroidOS draining, had to install apps and **** again but its not so bad.

I'll try that tommorow, yes apps need to be installed again (my phone is 7 days ''old'' so I don't have so many apps)
p.s. did you installed all same apps and games ? I am asking this because maybe some app or game that you had previously installed was making android OS draining battery

if androidOS is draining then it is not your personal apps, its the android system, reset should solve that. disable syncing and 3g when not using.

Root it then download setcpu or free equivalent from play store. Set max CPU to 800.
Install crossbreeder tweaks.
All info is available just search.
Battery life will improve.

p.s. do i loose warranty if I do root ?

Yes, betterbatterystats the best way to narrow down whats causing the drain before you decide to wipe everything.
You'll lose warranty while you are rooted, but you can always go back to stock, and no one will ever notice
Only problem is if something gets damaged so bad you cant use odin to flash. Then you might have problems
to restore it to default state before service.

I'll try it all, just need some time to experiment, I'll post my opinion and results
p.s. I disabled this:
s-voice
active aplications
bh telekom (some app from my network provider)
game hub
samsung account
sns
software update
also all the time I am on 2G, wifi is almost all the time on, brightness is set low as it can be, power saving mode is on, now I turn of vibration for calls, etc

for me, the battery drainer was the Dropbox app(maybe i didnt set it right)....anyways,it wasnt showing that it was the Dropbox draining..i mean after i installed that app my Android OS went over 50% usage while it used to be below 20% on those battery charts...
anyways after i uninstalled it,everything went back to normal,getting easily 1 day heavy usage(gaming included), or at least 2 days of medium usage( just regular calls and text and some viber over wifi)
so, from my experiance so far(have the phone over 6 months now), i recommend you to try to remember which apps you installed last and uninstall them...restart the phone and see if that works b4 you go to factory resets and all that stuff....cheers

since I installed task killer and set it to crazy mode (killing apps every 30 minutes), and disabling many apps to get notifications (list of apps is 2 post above) my battery with medium use endurance is better, it last more then 24 hours but I think that battery could last for 2 days with this kind of use. here is photo from betterbatterystats, is anything unusual ?
p.s. next testing step is to do factory reset or install some other kernel version

task managers drain more battery imo because they wake up the phone every time and kill apps in the background that will just restart again because they are set to run in the background, android automatically kills tasks that you ran earlier after an amount of time, anyway more info here

Install Juice Defender, the free version can solve your problem, increasing 60% the battery life.
Set aggressive profile.
I'm using JD on S3 Mini and Note 2.

tnx, I'll try this app also,
I downloaded ultimate version
@fcasoli
did you feel the change of battery life on that ROM AMG1 ? did you use some other ROM on 4.1.2 before that ?

the difference is visible with any type of ROM.
I'm using the last from SamMobile since the first day with my devices...

I've tried also the AMG1 Rom, but i didn't see any difference btw. this and other roms.
I've also tried to use a unrooted rom and there is also a massive battery drain.
now i've ordered a new battery. perhapes it lasts longer.
stiff

I do not have this problem, but I use a PL ROM from T-Mobile - AMB2.
