[Q]Battery Life on LG O2x, how to make it last long?

Hey guys, just got my O2x a week ago and its great. It was flashed with 2.3 and at some point I tested updating using LG Suite and I went to 2.2.2
Anyway, just asking if how long do your batteries (stock) last? Tested mine about 3 days ago and within a day it got drained. Just using browser and played some music and that's it, no Youtube or heavy games or whatsoever. Already rooted my phone and removed everything that LG has there except for the keyboard, Suite, Mobile Support, and Home Launcher. Still, same results. Please help!!

I have been using the free version of juice defender and that has help my battery a little so I now cab get a good couple of days out of it. The free version only really stops data when the phone is locked but it seems to work quite well. I also installed juice plotter to see when my battery gets eaten.

Thanks will do that. So basically battery drains more if mobile data is on? Haven't really experience that on my old phone (which is not Android OS).

I had to charge mine every night and sometimes 2 times a day.
Now, on a GB ROM, and with mobile data OFF, it last for at least a day (24h). This is with WiFi on (when awake of course).
Install a widget to quickly turn on/off mobile data, and only use it when you need. Then your battery will not drain that quickly.
Sorry for my bad english
My battery "record" is over 2 days Well, actually allmost 4 days, but then I didn't have WiFi on neither..

Mobile data is the killer only for badly done apps. Things like fb and twitter that sync every hour etc. Make sure when you install every app you check its sync status. Make them as infrequent as possible
Also try see how low you can get the brightness. Mine stays at 30% until out in the sun (have a widget to up it).
Remember even if not using your phone at home etc to switch tho wifi on as its much better
On good days can get 30/40 hours between charges when low use

Worth to mention is that to get the less battery drain from turning on the wifi you have to turn of the data. Some people forget that and leave both on making it a double drain.
My only tip that I have that I know works is use it as little as possible. Turn off every thing that's not needed in the matter of syncing.

I'm no expert but is that right? All of the data goes through the wifi when on and connected so data connection is irrelevant surely?

Thanks for the input and somehow, I can feel the effects now. Also put LBE Security and turned off most mobile data permission on my apps and even if my Wifi is on, not much of a battery drain but at least it has less loss.

i think that 1day is the real time of this battery with 1charge...intense use...

Yes when wifi is on data is automatically off.... You cannot have both on...
Wifi is no very power consuming when it's connected idle to a network, but think to turn it off if no hotspot is there because network scan drains a lot.

LOL.. anyways, i use juice defender. It does help somehow.

I have a same problem. Using my Optimus with MIUI ROM (Gingerbread 2.3.5) i only have 7 hours.
In my opinion,turning off all data connection to improving battery life, it's not a good idea when we choose Android phone.
So?

O_O My phone came with v20c 2.2.2 and had no issues, ran 3days per charge. Wish I had backups of original ril and BB for they were 100% on any I've tried since going through a bunch of custom roms.

I get 10 hours of *idle* time with 3g enabled. With Juicedefender things are okay, I almost always make it through the day and sometimes even 2 days when I'm not doing anything, but the battery just goes nuts if you use it. Sometimes I browse the web for a minute and bam 5% is gone, and I'm thinking to myself "what the hell just happened?".
You have to be very careful with apps that do not close properly. I discovered that Spotify was draining my phone like crazy and causing it to become very hot (draining it even faster, heat = dead battery in no-time) with no way to prevent this other than uninstalling the app. Then I installed a beta version of Spotify from their website and all is well. AccuWeather also goes nuts sometimes but that's resolved by deleting the widget on my home screen.
I run the latest nightly of CM7. Battery life seems to be about the same as the stock ROM for me. What's interesting is that active 3g data use drains the battery more than playing a game. I can play emulated PSX games for about 5 hours straight on a full battery with data controlled by JD.

Everyone should try the latest rom v20e (or the derivated version topogigi's rom). For me, it improves battery a lot! I don't even use Juice defender (and some people said it worsens battery).

v20e
yes Im on V20e and my battery is preety good !
Almost 2 days and I write almost 100 messanger/day and always wifi on checking emails,fb and more !

Hey guys, haven't posted since testing for about week, I guess...
Anyway, battery seems to be ok now. Juice Defender and Plotter works great, plus now on sleep, it just drain 1% per 2-3hrs or sometimes nothing at all, and its not SOD thats for sure.
Also tried Battery Calibration, it worked somehow also so with lots of messaging, wifi, FB, Tap Sonic, plus downloading torrents, lasted 24hrs in full charge with constant use.

2g + Wi-Fi drains the battery much faster than 3G + Wi-Fi for me. Both have a good signal strength.
Anyone know why this is?

What's you fav battery saving tricks/tips/tools....

For me I switch off all my WiFi and 3g and turn powersavemode app on works like a charm 15% battery drain over 7hours....
Any tips on how to save battery w/o having to switch off WiFi/3g?
Sent from my LG-P970 using xda premium

15% drain in 7hrs... doing what??
I mean, I loose 4% in 8hrs sleeping [doing nothing] and if I turn on airplane mode it varely loose 1% in 8hrs sleeping

i loose 3 to 4 % on 8 hrs too with wifi off

Is it possible to actually damage your batt by over charging, I know it was possible before, but some ppl tell me nowadays batt don't do that anymore...

I don't know man "a bit" is no accurate thing but I thing I have almost the same battery usage... I do a lots of txts...
now, for the overcharging... as far as I know all [or almost all] new electronic stuff that needs to recharge has a sensor for voltage and power, so when the batt is low or empty it tell you is the same when is fully charge it tells you and "cuts" the power supply... if you have some time look at your phone when is charging, when at 100% it tells you and "cuts" power, a few mins later it will be at 99% and inmidiatly starts charging again

6 hours sleeping it only drain about 2% from 37-35 yesterday
No special app used in my black right now,cause i'm waiting for the new updates
But to answer the title, it's Juice defender
It saves me a lot when i forget to turn off the conn

I use JuiceBattery ultimate in order to save my battery, and still every night with no opened apps, about 12% drain. Is it normal?
Is it possible that Juicedefender does the opposite - draining the battery?

I honestly don't know how are you manage to get such low power consumption on your phones. Just today I unplugged my phone little more than 5 hours ago. I did absolutely nothing with it, it just lied on a table and I'm already down from 100 to 84%. Just to be clear, for those 5 hours wifi, gps and 3G was off all the time. I'm on stock Froyo 10e, some of the LG bloatware removed and replaced with so called energy efficient apps from the market (3g watchdog, battery monitor widget). The only two original LG widgets that I use are weather & clock (with manual updated weather) and contacts. I really don't know what I'm doing wrong but my phone with really minimal usage can't last more than 1 day .

I had probs with battery monitor, it drain batt like crazy so I uninstalled it and prob is gone... some of those apps kill more than what they save
the only apps I have is juiceplotter to monitor battery, cpuspy and android booster which I found very usefull cause it turn off everything: wifi, 3g, bluetooth, apps not in use; all in 1 click and as far as I know it really doesn't drain any battery or it's so minimal that it's not displayed

Ok currently I'm trying the higher voltage charger (5v) trick and I can see a huge difference ald I don't know how it works but 0% drop in 6.5 hours WiFi, 3g off and 10 sms Woot!

what trick is it?

Apparently cos our stock charger is only 4.8v and our batteries are 5v/1500mah so if we use a 5v charger somehow it helps with better charging and battery life, I'm using a bbm charger which is 5v
Sent from my LG-P970 using xda premium

well i root my phone then removed the system applications using -system app remover.
im getting a much better battery backup . at least 30-40 % better . as far as the stand by is concerned .
i play a lot of games and text a lot so phone does not last over 1.5 day now ,
earlier it was one day only.
so im relatively happy with this phone because the battery backup is better now.
hope a software update to gb will help even more

do you guys have a battery percent number of 99%?
my phone ALLWAYS skips the 99.. it goes from 100 to 98 in 10 min after doing nothing..
(it's in the nova rom, its with official stock and it's with cyano.. and batt stats are renewed enough..)
PS: not to mention how poor my phone is daily.. chargng in the night.. at the end of the day 20% (too little to have all day at school, too much to power it up at night.. )

Ah ok! I use 5v charger since i bought the OB. I charged it only 2 or 3 times with original charger and the battery life was a little lower than 5v charging

I reboot mine every morning. It seems to make some sort of background task started by alarm or something.
A normal day at work leaves me with 80% left.
If i don't reboot it will eat up the juice in just 5 hours.
Also juice defender helps quite a bit.

K this has been helping me with my battery alot
1) install a new rom
2) using 5v charger
3) installing a firewall and prevent unnecessary stuff from connecting to 3g
4) uninstalling task killers(takes alot to restart the apps you killed)
5) uninstall battery monitoring apps (surprisingly)
6) use stock included lock screen
--------------------------------
Added:
7) uninstall anti virus apps*if you dare* (cos from what I understand Android has a sandbox type thing which traps viruses sorta so unless you go to alot of dodgy sites often you wont need it, imo a firewall is enough)
8) Turn off automatic updating for apps in the market
9) Turn off un-needed snyc features but do not turn off the "Background data" sync and "Auto sync" under the General sync settings or you might face problems going to certain sites, instead turn them off individually via the "manage Accounts" menu (I turn off mail snyc, fb snyc, watsapp snyc, contacts snyc)
Personally this had helped me alot in terms of battery....

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

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.... :/

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

Low battery

My phone is having a really bad battery life.It can't last a whole day and it discharges extremely fast.I looked at "Battery" in settings and nothing looks suspicious.Even in standby mode it discharges like crazy ( overnight i lose about 30% of battery ).Phone is completely new.I don't want to disable live wallpaper, wifi, mobile data, sync etc. because i bought a smartphone for those features.Any other suggestions are welcome.

That's normal for the stock ROM, flash my V3 ROM you'll have 2 or 3% drainage over night.

I get super draining aswell after flashing dmod v1. I can't be bothered to keep flashing roms so I'm waiting for cm or benzrom v4.

Turn off your live wallpaper en weatherclock. Those 2 keeps the phone awake. I have with 3g allways on slight browsing loads of texting and whatsapp few calls and most of the time online on facebook, 20/27h of battery time. When i dont use my phone alot it can go up to 35/40h

No live wallpaper and no weather clock. Most bloat ware removed, Using golden kernel hotplug governor and seeder. With benzrom I had 20+ hours with heavy use. Since dmod I get roughly 10-15 hours. 30% drains overnight.

So strange,there are no significantly changes in DMod, compared to the base BenzROM! Essentially frameworks and apps are the same

I know man it doesn't make sense but I can't wait for another better rom that will hopefully fix this issue with a clean install.

Yes but you're forgetting about build.prop tweaks, they play a big role when it comes to battery drainage.

I just installed Benz rom, so i am hoping for better battery life.But there is also one more thing i noticed.I installed no frills cpu and i noticed that minimum frequency is 1 ghz !!! I set it to 200 mhz and i think that will make a huge impact on battery.I will be posting my battery stats picture soon.

So many advises about installing other rom. I think you need to try to remove huge battery drainers first. Try to disable Picasa web-albums sync (this **** eats alot! ) and some other sync that you don't need. You need to change it for each Google account you use on your phone. That's all. This small change halped me alot with battery drain and, I hope, will help you.
Also, you can freeze apps that you don't need to. It can be made without root.

In screenshot you have a very weak gsm signal in your area. This drains your battery.
If you don't use 3G/HSPA mobile data, you can try to manual switch to 2G network (2G band use less power from your battery).
HTH,

Ok, so installing a new rom and messing with CPU frequencies did help after all.I installed Benz rom and changed minimum cpu frequency from 1 ghz to 200 mhz.Battery now lasts 2-3 days with light use and about 1.5-2 with medium use.Battery discharge overnight is about 10% with sync, wifi etc. turned on.

hmm,i dont know what apps you have installed on your phone,but when i installed Dropbox app few days ago, there was a massive battery drainage overnight...it eat my battery between 30-35% overnight...and it used to be only 3-5%...
of course i uninstalled the app and now its back to normal,only 3-5% drainage overnight(wifi and sync off)...

[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....

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:

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
