[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?

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.

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?

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

Bit of games, calls and texts....
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.
Sent from my LG-P970 using xda premium

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....

[Solved] Battery drain even when idle

I charged my phone to 100 percent and left it untouched for 6 hours. Then a shock. It was down to 81 percent with absolutely no usage. Please help. I was not connected to either wifi or data.
Edit 1 : it drained from 81 to 73 for a 5 minutes use.
Sent from my Android Rocket using Xda Premium

Akilesh - you need to see if any app was running. Over the weekend mine went from 60% down to 12% because Titanium Backup got stuck trying to delete an app and kept my phone running at 200mhz which will drain your battery. Go into settings/Battery and see if any app is at the top of the list. Your phone should not lose 19% if you dont have anything running/syncing etc. A simple reboot took care of the stuck Titanium Backup issue with me.

I am on full stock gingerbread with no root. Cell standby has consumed about 45 percent of drain. I'm now worried. Is there a way to calibrate the battery or reset battery stats?

Hello Akilesh, you could use an app called BetterBatteryStats to monitor your battery usage statistics.
You could root your device and then install Titanium Backup Pro which will allow you to freeze or uninstall unnecessary pre-installed applications by Samsung, which are aptly termed bloatwares.
If you do choose to root your device, kindly follow this guide by dr.ketan, http://forum.xda-developers.com/showthread.php?t=1424997
I hope this helps a bit.

screen brightness is one of the prevalent causes of your phone's battery, lower it down to a minimum level. Check if you have syncing apps in the background too, Uncheck background sync datas or account in settings if you have then check.
Now, install cpu spy from google play https://play.google.com/store/apps/...251bGwsMSwxLDEsImNvbS5idmFsb3Nlay5jcHVzcHkiXQ.. and check if your phone is in deep sleep or not at all.
Also, quit using live wallpapers (if your using one), though as you said your not using your phone for 6 hours.. the fact that if you do have a live wallpaper running, that will still eat up your phone's battery juice.

maybe it's about high time you consider rooting your phone.. so that you can install titanium backup and shoot those power hungry apps that are hidden somewhere in the framework of your system.

Yeah I'll root in a short while cleo. And is titanium back up useful is reducing battery drain?
Sent from my Android Rocket using Xda Premium

titanium backup is a tool to uninstall and freeze unnecessary apps and samsung bloatwares on your phone. When your going to remove those apps, you are not just reducing power consumption that those apps uses daily on your phone... you are also freeing some ram spaces on your phone's storage.
BTW: My name's John and 'Letters to cleo' is a name of a band that I like most.

In case you opt for a free alternative to titanium backup, there is this app called "AntTek App Manager". I found it by chance and it works exactly likeTB pro (in terms of uninstall and freeze). You have to be careful while using either of these programs

i think you install an app that its drain your battery . if you dont find that you may reset factory your phone

Just got rooted again. Now freezed all bloat-ware. Will check out how it works and post back again.
Edit : Feel the phone running a bit faster after freezing some 15-20 applications.

dont forget to try recalibrating your battery as well.
Mind you, rooting has far more greater advantages than disadvantages.
Check later on if your getting that perennial issue or not anymore...lf by chance it had made some considerable differences, then your a happy camper..
Cheers bud!

If your phone is getting into deep sleep, it can't be any application! It has to be something to do with wifi/Network! If you run 3G, try disabling fast dormancy. That did me wonders!

Battery Drain
Hi Guys,
I have similar problem. My battery started playing up and keep draining suuuper fast even at full charge. My phone and bat are already 11 months old but I don't thin the battery should die with this short time. I have data always on and screen brightness set to minimum and it has been like that since I have it with no problem. Now, after charging to 100% and removed from the outlet, then start opening an application, it will freeze and won't turn off. I need to remove the bat out to have it rebooted and it's still the when I try again. Other behavior is that the screen will flicker, will turn to airplane mode, and it will turn off even when fully charged when I launched an app. Note that (power saving is OFF and just the same when it's enabled) I can now only use my phone well when connected to charger. Any help would be appreciated. Thanks.

there are a lot of people facing similar issues with more than 9 months old battery... mainly indicates a battery problem.. but first you should install betterbatterystats and check for wake locks and other apps using the phone when idle and eating up the battery..

My biggest drain according to bbs is Google maps, it's eating my juice when in idle, although I can get into deep sleep bbs says maps is causing wake locks.
Should I just freeze it with titanium? I don't really understand bbs much lol

Not going into deep sleep!

I have always found the battery life to be poor but I have come to accept this device has a large screen and great processing power etc!
My UK phone is rooted on the latest ICS and has various apps frozen with titanium backup manager! It use to be in deep sleep mode for about 68% of the time but since 2 days ago cpu spy says it hasn't been in deep sleep mode! I have installed various apps that kill running apps but the phone fails to sleep!

hello sir..
hmm since i read that you installed various apps that kill running apps, maybe that is cause to kernel wakelock since your system always working to searching what app running and killed it in various time you set
..many system app that switch back on like google app no matter you turn off except you log out your account
or maybe you can try one off the famous airplane metode which is
- switch your phone to airplane mode
- turn off your phone and pull out your battery (until 10 sec or more)
- put again your battery and turn on your phone
- after complete reboot let it for a while then turn off the airplane mode

I had the same problem with audio_out one but only in imilka's paranoid Android.. Couldn't fix it in any way so left the rom..

the reason taskkillers are disputed is because memory works different on android. It reloads certain stuff afterbkilling it, causing a cycle of killing and reloaded that can cause more drain than is intended to safe

[Tutorial] Battery saving techniques

So yes this Phone's battery unfortuanatly is not well at all.. but here is how i managed mine to last a day without charging. Let me also say im a heavy user also. I text A LOT and always pull out my phone in class play a few games to pass the time or just browse my phone. So this does work for heavy / light users.
Go to Wifi/ menu / advanced and click never on Keep wifi on during sleep.
Go to settings/ Location access - Switch to off
For your brightness it will be on Auto switch that off and put it almost to the lowest as you dont really need it high just kills the battery.
- Go to the App store and download Easy Battery savor. When you access the app choose intiligent mode. It really helps !
-Dont ever use live wallpaper it just drains it so fast.
- DOwnload Faux App It really helps (Faux kernel Enhancement Project) Once downloaded go to CPU and set max clock to 1.35 instead of 1.5. it will still be buttery smooth and it will drain the battery less.
Also I am using the Franco Kernel - nightly #53 which in my opinion really helps !
- Try to turn off the WiFi usage as much as possible and you will see a huge difference.
That's all from me guys. By doing all this my battery significantly improved and lasts about a day now.
Anyways if you have better solutionson how you manage your battery and how you extend its life.
- post pictures
- post the apps you use
- post everything !
Thank you !

I use harsh. Whenever I don't game, I lower the max freq to just 810mhz, ondemand, row, mpdecision on (as harsh recommended) and it's still buttery smooth, and of course battery life is incredible, and I also do check the Disable HW Overlays and Force GPU in 2d rendering. And since no kernel controlling apps are needed, my phone feels cleaner too I can't upload battery stats yet as I'm in an area with only edge connectiom and I hate using slow internet connections

Sent from my Nexus 4 using xda premium

A couple of things I noticed with this. The first thing I notice is, in two of your screenshots, you appear to have mobile data disabled completely. The second thing I noticed is that your final screenshot shows 24hr 52 min on battery, yet according to your clock, a it should really be a total of 33hr 6 min since unplugged. Your first screenshot shows 88% battery remaining with it already having been unplugged for 7hr 35 min. With that screenshot showing a time of 3:11pm, that would mean your phone was unplugged at 7:36am. If the phone was unplugged at 7:36am, then how is it only showing a total of 24hr 52min at 4:42pm the next day? It should be showing 33hr 6min. That's an odd inconsistency there. All in all, even with the data that is showed in your screenshot, it shows very little use as phone idle and cell standby are both in your top 5. Your screen was your highest drain, yet there isn't anything else there accompanying it. I could be wrong, but it seems to me that all you did was keep the data turned off on your phone, and connect to wifi where available. You turned your screen on, but didn't really do anything with the phone besides having the screen just on. That said, even stock with no changes, a person can get 24 hours on a charge if they're disabling their phone and not using it.

Interesting tips however I have a few points:
Your first tip suggests having WiFi to Never stay connected during sleep. I am part of another Android forum which deals with tablets. We tested this feature as with a tablet, you are likely to leave it for hours on end before using it again. It was excellent if the tablet was not touched, however we noticed that it significantly increased the battery drain if you were regularly switching between sleep and using it.
Agree with the second but don't throw away practicality, use Location settings when they need to be use, not just turn them off and don't use them.
Leave it on auto-brightness dude, why ruin the nice visuals of a fantastic screen by having it so dark you can't see it? I only ever use lowest brightness when its dark or the battery is nearly dead.
No idea about the battery saver.
I definitely disagree with this. If you use 3G permanently, like I do, then turning on WiFi definitely reduces battery drain. I don't turn off data ever, so switching WiFi where possible is quite a useful battery saving technique.

We tested this feature as with a tablet, you are likely to leave it for hours on end before using it again. It was excellent if the tablet was not touched, however we noticed that it significantly increased the battery drain if you were regularly switching between sleep and using it.
Agree with the second but don't throw away practicality, use Location settings when they need to be use, not just turn them off and don't use them.
Leave it on auto-brightness dude, why ruin the nice visuals of a fantastic screen by having it so dark you can't see it? I only ever use lowest brightness when its dark or the battery is nearly dead.
No idea about the battery saver.
I definitely disagree with this. If you use 3G permanently, like I do, then turning on WiFi definitely reduces battery drain. I don't turn off data ever, so switching WiFi where possible is quite a useful battery saving technique.

His solution is to turn off connectivity and functionality on the phone. That defeats the purpose of even having the phone at all.

That said, I think a safe UC of maybe 200MHz can have a difference, but to me, it's all about enjoying the phone and the phone experience. No need to screw with it

Don't do the wifi feature. It will use more battery because it will constantly have to reconnect to the wifi connection every time your phone comes out of sleep mode and that will consume more battery.

Crisis, I pointed that out above...

Someone tell me how I can go all day AND listen to 8 hours of Bluetooth audio and I will be impressed.

Just curious, why did you buy it then? Personally, I'm leaving everything on because I bought the phone for the looks and usability.
And yes, the phone lasts me all day while using it for everything including emails, conference calls, web browsing etc.

I've set up profiles using the Smart Profiles app to quickly turn things on and off at will - hit CAR and bluetooth/GPS turn on, Wifi turns off. Hit HOME and the reverse happens, etc.

Same thing here..but I use scripts When I'm in school and all I need my phone for is some tethering and music, I activate my script that sets the max freq to just 810mhz and I undervolt an extra -50mv from the stock undervoltages of harsh, but when I'm out and away, I enjoy the full 1.5ghz quadcore beast trapped inside my pocket

Don't get me wrong, it's useful to have a decent battery life, but I really don't see the need to turn the device into an expensive brick. My suggestions, which may or may not be better than the ones in the OP, but they seem to work for me on every Android I've come across without screwing with undervolting etc:
1. Turn Auto-Sync off, or increase the duration between each sync. On my old phone, the phone would use Auto-Sync every hour or so which totally killed the battery over the course of day. I turned it off and would sync it manually (taking all of 15 seconds) on a Friday. Made a huge difference, although simply increasing the time between syncs is just as effective if not more so as you still save a bit of time (might opt for that myself :good
2. Use Inverted Apps on SAMOLED, Don't use Inverted Apps on IPS, white colour uses more battery on SAMOLED, but a lot less on IPS :fingers-crossed:
3. Get yourself a Toggle-based Notification bar, you will remember to switch off your WiFi when walking around in public. To that end, switch your WiFi off unless you are connected to a hotspot, the constant scanning will drain your battery and depending on the interval may take quite a large hit over the course of a day. If you rely on WiFi then maybe increase the scan interval time.
4. Turn off all mobile networking services when in a known signal blackspot. e.g. When work pays for us to go to a hotel on the Welsh border in Cheshire, there is absolutely no signal guaranteed unless you go to the end of the driveway, so I turn off all phone services unless I am there. Your phone will drink your battery very quickly otherwise, guaranteed. The easy solution is to use WhatsApp, switch your phone onto Airplane mode then turn on WiFi and connect to a hotspot (if they have one available, hotels usually do). This is surprisingly low on battery consumption.

So basically, just leave my phone in my pocket and not use it. Okay. Gotcha.

My battery life is amazing. I guess it just depends on what you compare it to. I had an evo 3d before, and my 3d would be dead by noon without even turning on the screen. My work blackberry lasts 5 days with fairly heavy email usage.
My N4 though, I use it fairly often for browsing, occasional calls throughout the day, streaming audio, this and that. After 12 hours of use I am still at 60% usually. From 7am to 5:30 (typically when i get out of work) I will be at 70%+
Not sure why people are so bent out of shape about it...
On my 3d if I ran facebook app or any stupid **** like that it would kill my battery like i didnt even have one.

Here's another idea get a job or pay attention in school. That will save battery life as well. I have literally seen people stare at a screen without doing anything with the phone, just because they are so obsessed with it being in their hand
Oh and my Sig does not represent the nexus in the mail

What about those external battery things? Does anyone know where I can find some decent ones online?
