serious problem with battery life. - LG Optimus L9 P760, P765, P768, P769

Hi guys, I got my new LG P769 at Bestbuy two days ago and I think my phone have a huge problem with battery life.
As you can see a picture, it discharges so fast. There are three cliffs of its batter life in the picture, two big cliffs and small one.
It seems to be abnormal. further, battery was 75% when i went to bed last night but i noticed it went down by 35% while i was sleeping.
of course i didn't use it at all for 6 hours. The second cliff was occurred at that time,
Do I need to go to complain? Please let me know how to deal with that. Thank you!

Hello Mate,
I too felt same feeling when I purchased this phone first.
But later I realised few things.
1) When you have inactive card with no signal, It keeps on searching for the network and drains a lot
2) The DISPLAY is by default at 100% and if you take it to 50% that is sufficient for indoor use, You save A LOT battery.
Now when I take the display to 100% it feels too much for me. When you are outdoor, you can raise it to readable level.
3) Keep on cleaning tasks and running apps. They DO EAT power even when you are not using the phone.
4) Same applies to the widgets. I really could not find personal implication of Weather widget that have storming animations and lightening data usage. (I am not a pilot nor sailor. No pun intended)
5) When your battery is new, you have to charge it to 100% at one go and use it till it discharges completely before you charge it for the next time. I read its called Conditioning of the battery. means telling it its limit of upper and lower value. This helps long lasting battery life.
6) last but not list and common. When Not in use keep WIFI, Bluetooth, GPS turned off.
They are hardware on our fone and demand their share of power. If you are too wary you can disable the autorotation also, that means one more sensor off and boon to battery. I dont turn it off. I need it a lot and often.
Some Few Tips I did more
1 Disable the Vibration
Vibration = mechanical Motor = Horse Power to eat your battery grass
2 Keep a dark wallpaper.
Light = Power to Light White bulbs on screen
Remember you are running a Dual core 4+Inches beast so you can not expect battery specs like simple fones. You can only smartify it to last longer through the day.

False information. This device does not have an OLED screen so the pixel color has no effect on battery life.

[Q] Battery, Screen power and your mileage

Greetings,
First off I'd like to say that I absolutely love this device. I had the Evo 4G prior to this but about 3 months ago I dropped it on accident and destroyed my screen, then tried to replace the screen myself and it didn't go so well so I have spent the last 3 months using a Rumor touch to tide me over (). I'm happy with the Evo 3D beyond belief but I had a few questions to ask because I am not getting the amazing battery life that people have been so thrilled about.
First off I have background data disabled, auto sync is tuned down but not turned off completely (though it is turned off for things like htcsense.com and the like, only on for gmail and weather). I have adjusted the screen brightness down to around 20% but occasionally bump it up in high-light situations. I've also installed Juice Defender which helped a great deal, but I'm still noticing some strange behavior.
Is it common for the screen to be hogging the battery life like none other? I was able to go 14 hours yesterday with Juice Defender on, but i was also working for 12 of those hours and using my phone very little, so i'm willing to say that 80% of the time the phone was in standby/sleep mode (and i verified this by looking at up vs awake times). The thing that baffles me about this is that the battery usage says that the display used up 80% of my battery. How is this possible when the phone's screen wasn't even on that entire time, does the screen really pull that much power when its on?
My capacitive buttons are on full brightness while the screen is on no matter the light situation, is this as intended or could this be a defect drawing too much power?
Anyone else having battery problems?
i have issues when im at work with little to no signal which zaps the battery pretty hard, do you have issues with signal? (you can check under the batter graph, cell standy should list a percent without signal, mine yesterday was like 44 percent from being at work)
Other than that how long have you had the phone and have you calibrated the battery? It should improve over the first few charges, especially if you've calibrated.
That's odd, i have pretty decent signal here but under the "cell usage" i have 75% time spent without signal but the cell usage only was 8% of total battery use, and still 70% used for the screen. Does JuiceDefender turning off the 3g account for any of that 75% time spent without signal or is it truly phone signal loss
Sorry yeah I did calibrate the battery before the 14 hour period i was referring to.

Battery Life

Hey guys,
How much battery life do you get on your X2?
I just installed CM7 and I'm down to 60% after 5 hours of LOW use :/. Could I need a new battery?
Are you doing anything with the settings of the CPU, such as setting minimum frequency, keeping both CPUs online at all time (this might be set via tweaking scripts)?
In fact, ARE you using any type of tweaking scripts (V6 Turbocharger, speedy, etc)?
I don't use any of them and my battery life is pretty good. I also have an extended battery as well, so that helps.
Let the ROM settle in. After two days you should get a better picture of what it's like. Don't forget to do a battery calibration. I haven't even done that yet and have been lucky enough to have great battery longevity. Can also look into managers like Juice Defender. There's also another app I have used in the past that can limit when an app can run. Like limit Facebook from always running in the background and syncing for data. Ithink it'd LGE or LBE security?

Are you using the beta and not the alpha? The alpha has a problem with running the CPU at a high percentage when it shouldn't, which cause the battery to suck.
It is possible that you may need a new battery, but more likely is that the X2 simply has notoriously bad battery life. There are, however, things you can try to help. Go to your settings app, scroll down and click on "applications", and from there, open "running processes". Check out some of the processes. There may not be any, and if you see processes running for games or apps you haven't used in the last few minutes, it may mean that they are constantly running in the background. In that case, you may want to consider uninstalling. Try to use wifi over 3g wherever available. Screen brightness is a major battery killer, and as such, may want to keep it on the lowest setting; I've found it to be the most noticeable improvent in battery life. People are going to tell you to calibrate your battery, but I've done that many times on 2 X2s, never seen a difference. My friends and I agree its just a myth, but there's no reason not to try.
Honestly I don't know squat about batteries, but I remember hearing that the voltage of our batteries is 4.2 volts. If that's a measure of capacity like I think, you can try the app "battery left", which I believe has a voltage meter. If its less than that, maybe you should consider a replacement. Please don't take my word on this though, I can't confirm any of this to be true lol. Maybe someone else can offer their opinion on battery health.
This whole post probably seems like a big collection of thoughts. I'm tokin' right now, took me like 20 minutes to type this.
Hope I could help
To add to theredvendetta's comment, if you have your email set to check for messages, it can really have an effect on your battery. If you set it to never check, I'll bet you will see a difference.

I have nothing of the sort extra installed (CM7 might of had this stuff, but I don't know).

I am using the Beta.
@theredvendetta: I installed the Battery Left widget, and when I go into details it's saying some interesting things.
I'm at 50% battery right now. For one, its saying my battery is at 3787 mV. 3.8 volts I would say considerably lower then the 4.3 it should be. My battery is only ~6 months old, but, for 4 of those months it sat unused, uncharged, and in my hot/cold car. I've only run it down a bit and charged it up 4 or 5 times this week since then.
It is reporting "battery health" as good, but idk.
Under "Accuracy" it's saying the charge reading is "Inaccurate" and the bar is totally red, indicating that the estimation of charge is very inaccurate.
Where can I calibrate the battery? I'll look around under Settings for now. EDIT: It's likely I was only around 60% charged or so when I installed the rom.
And as for background tasks, aside from the default stuff and my few widgets (not a heavy user of those) there's just Facebook+Words with Friends, Songbird, GO Keyboard. Not too terrible, I think.

I probably should have said this to begin with, but when I was talking about the voltage, I meant 4.2 was the charge when at full charge. I can see I worded my original statement poorly, apologies. Try charging up to full, and then check battery left.
When it says "innacurate", its reffering to the battery percentage reading its giving you. When you have cycled the battery once or twice, it will tell you it is "accurate", and the bar Williams turn green. You may notice parts of the bar turn green while first using the app; this means its picking up readings for the percentage of battery you're on at the time. I mean if you're on 50%, it will soon turn green halfway through the bar. After you have completely cycled the battery once or twice, it will stay green and accurate until you reset it or uninstall.
To calibrate the battery, you have to enter Android recovery. I can't remember 100%, but I believe that you hold the up volume button while booting up the phone. It may be down, you can try both. Hold it until you see text pop up that I think says "fastboot". When you see this, let go of the volume button, and now hit volume down until you see text that says "android recovery". If you accidently cycle past it, keep clicking volume down, as the list loops. When you stop on android recovery, press the up volume key. After a few seconds you will see a new screen with an exclamation mark. Press the up and down keys at the same time. A list of options will now appear. Don't use any of them unless you know what you are doing. There should be an option called advanced or something similar. Cycle to it by using the volume keys, and hit the power button to select it. There will be an option to calibrate you battery in there. Itbwill take a few seconds, and after that, return to the main menu and reboot the phone.
Good lord that took me ages to type. There's no hope with dope kids.
I feel like a broken record, but again, battery calibration does not do anything. If there's a chance the meter is off, just charge until your battery's voltage levels off and use the battery fully before charging again.

I agree with you. He asked and I answered. 'Sides, there's no harm in trying it, as there are no negative aspects to it.
Im running cm7 and the only mod im running is the 8 touch points. I do have my screen set to the most dim setting thoough. My phone gets unplugged at 5:30 in the morning though out the day I'll talk send some text might play a few games and usually be on the internet about a hour or so. When I get off at 7pm my battery is usually anywhere from 75% to 69%. A few times it has gone 18 hours and only been down to 52%. Give it some time, CM7 has by far the best battery life that Ive seen for this phone.
Yeah, after clearing the davlic cache and going through a few charge cycles, it seems to of improve greatly.
I'm running CM7 and my phone has been unplugged for 23.5 hours with medium usage including 72 minutes total voice call time and I'm currently sitting at 23%, hence my signature lol and this is a stock battery.
SBF'd from my tasty X2 MAXX
give it a few days but cycle it hard, like don't plug it in until you're below 5%. I have the BH6X (1850mAh vs. 1600mAh) so it's not much of a jump in capacity... your voltage should start out right around 4.2v and drop to about 3.5 when it's close to dead. My phone sucks at telling me how much battery is left, it always has, I typically run this thing dead every day, but some days I'll have upwards of 40% left (voltage is still above 3.8v)
I honestly don't even pay attention to the percentage 'cause I can watch an entire episode of beavis and butthead in HD with the brightness all the way up using software rendering (more power consumption) when I'm below 10% and it won't shut off on me.
it takes me almost a solid two days to kill my battery and I've been on CM7 Beta for a week as of yesterday. at first my battery life was absolute crap, but it has improved... every time you wipe the dalvik it'll take a solid 2-3 days to rebuild it. that uses much more power.
I am prepping for CM7 now. With my mostly stock X2 using Juice Defender I am getting about 1.5 days between charges. When I charge I am about 20% or less on the battery and this is with mostly lite usage. I expect once I make the switch it could take up to a week for everything to level out as it will have to synchronize many things because it will be like having a new phone. When my X2 was new it took about a week to settle in and stop the random crashes. That was also about the time the battery improved from about 1 day between charges. I will write back in a week or two once I have my phone switched and stable.
I used juice defender for awhile but I realized I was really only using it to control data. I just keep a data toggle in the notifications bar. It's really not that much of a hassle to switch it off and it reconnects fast enough. Saves quite a bit of battery power. When I was doing that with my extended battery on liberty I could get about three days.
I am actually impressed with my x2's batt life (although it is a brand new batter when I got the phone a few months ago). I used to have the HTC Desire, and it wasn't the greatest with battery life. My bone stock x2 didn't have the greatest batt life when I first got it, and still wasn't a whole lot better with cm7 installed. But now that I have installed miui on it, and screen brightness is about 70% constant, with wifi ALWAYS enabled. I am going on almost 24 hours now (maybe more??) and I am at 57% with little usage. I've used the phone maybe 2 times today for a total of about 10 minutes talk time, I have no 3g/data, other then wifi when I am at home, so I'm sure that has alot to do with it.
Another tip, that probably everyone already knows, and some people say it doesn't matter, but it seems to for me. ONLY charge your phone when it is less than 10% left, and then make sure it is charged for at least 6-8 hours before you unplug it. I know they say the newer batteries are not effected by this but my wife had the HTC Hero (worst android phone ever IMO), but she would charge it every chance she got, even if it was at 80%. Now, the phone is lucky to hold a charge for 5-6 hours with NO USAGE at all (except wifi always turned on). Granted the phone is older than dirt, and so is the battery, but still. My desire still holds a decent charge considering how old it is. I can get maybe 14-18 hours with no use on it (or very little use) with wifi always on (granted, the phone is bone dead after this time though).
I just altered the cm7 performance settings... back to normal. This combined with a custom juice defender ultimate profile has easily tripled my battery life..

Yeah I've seen nothing come from battery calibration. I have problems with my meter some days draining really quick and some days just normal. If it's bothering my I'll do a reset and that will usually sync it up. I'll try the charged voltage level off and empty thing and see if that helps.
Thanks.

[Q] Display literally destroying battery life

So across all roms I have tried the display literally destroys the battery life of my phone. While the screen is off I get fine battery life. But when the screen is on I can watch my percentage decrease about 2-3% every minute so after a half hour of browsing my battery is gone.
I have an extended battery as well but that just prolongs it slightly. The brightness is about half right now. Is this normal?
Does not sound Normal but display is the largest user of battery( unless one can use the phone with display off
I had as video streaming yesterday for 30+ min from 80% it went to 14%
haven't tried keeping just display on should try that ...test for tomorrow

I have my brightness set to 15% and it still sucks about half of my battery use. The display is unfortunately nearly unstoppable when it comes to battery drain. HTC and others are like "BIG PHONE DISPLAY!!!1!111!" we're all like "I can haz batteries?"
That description is the best description of our issue.
But an answer to your question, drop you brightness to as low as you can stand it and if possible try to limit the amount of times you wake the display in a day the juice it requires to turn it on is greater than it needs to sustain the screen on.
I would say yes for the most part. We have a fantastic and power hungry display...the price for greatness?
That being said, its not so bad dropped down to 25% or so, and easily viewable, except if you're outside.

Alright thanks. I just wanted to make sure my phone wasn't experiencing something that is atypical. Other than that I do love this phone and the developers
It's hard to say. With screen on I loose about 1% a minute even with auto-brightness turned off and the screen at around 25%.
There are others on the forum that have made rather amazing battery life claims so it may come down the the individual device.
I have debated about returning mine for a different one to see if I get any better performance.

I'm not sure I would bother chasing longer battery life with new devices. A lot of those are very optimized use cases -- either all on wifi, all in areas with great signal, or lots of screen on time but they don't mention what brightness. The fact of the matter is the phone has a tiny battery and uses up a lot of power for the display and radios. I get somewhere between 12-16 hours on a stock battery, depending on where I am and how much I use the phone (generally I'm a pretty light user, but I do leave 4G and Bluetooth on all day).

[Q] Battery life + Screen problem

Hello!
I've had my HTC EVO 3D for 16 months. Everything is stock . 1 Week ago my battery begun to drain awfully fast, up to 2%/minute at lowest brightness. Charging the battery with screen on keeps the battery at the same % or sometimes it goes slowly down. I tried to factory reset the phone (thought there was an app eating my battery) but it didn't help. Everything excluding mobile network is turned off. "what has been using the battery" tells me:
Screen: 78%
Cell standby: 12%
Phone idle: 10%
Is it time for a new battery or?
Question 2:
I've heard about many screen problems with the EVO 3D. My bottom part of the screen doesnt work (buttons does). I tried the draw test and it's impossible to touch the bottom of the screen. Anyone got this problem?
i had a similar problem. my battery drained WAAAY fast. only lasts about an hour on use, and 4 hours on standby. drain rate equal to yours as well. you say your EVO is 16 months, mine is 8. maybe my problem was the same as yours but half (lol). my screen was non responsive on the bottom at times as well. i also had this little dark spot on the screen. like a smudge right in the middle. it didnt affect anything but it was bothersome to look at. i got similar battery usage, but what the phone doesnt tell you is the truth about the radios. i live in a place with poor signal. and just recently i discovered that the worse the signal is, the more the battery will drain. because the 3G or 4G radio has to stay on for longer to retrieve data, which eats the battery in a flash. in your case it could be out of plain usage. i dont know. anyways. i checked the battery to realize it had a bump. like a little swollen. i also realized that with the battery cover off the battery kinda sticked out a little, unlike when i got it. realized as well that with the cap off the smudge on the screen disappeared, and the touch interface was not giving me trouble. then i arrived to the conclusion that poor battery life was due to poor reception, and the screen problems were caused by my battery applying pressure to the display from the inside. i bough a pair of replacement batteries from Anker, and i dont have any problems. the battery life is a little longer as well.
maybe that could not be the case with you, but check your battery just in case. and also try to run your phone for a while on airplane mode, and if you see a great battery life increase like i did, then its the reception. if not, the battery either went bad, or you have a battery vampire app lurking around. and if that is the case, try the greenify app (root required) so you can hibernate all apps while you dont use them, and eliminate their background process. and if after that you dont see any battery increase, or you notice your battery being a little swollen like mine was (if you dont see it swollen try putting it on a flat surface, and see if its laying flat), then yes, its time for a new one. it cant hurt getting a new one, using the same battery for 16 months should have decreased the battery's performance anyways. but note that if the battery life problem is due to network connectivity, a new battery will only help a little.
hope i helped!

Dissatisfied with battery life.

Why does LG think it's ok to ship a watch with a 12 hour battery life, with minimal use. Just setting up the watch took %40 battery
Without sacrificing screen brightness is there anything to be done?? Is there any sort of root + cpu app we can lower CPU speed with??
Did you uncheck always on screen? Only option I have off and notice decent battery life for the entire day.
Mine goes for 16 hours once completely setup. If you start downloading and setting up this will surely tax the battery on any watch. The 240MAH doesn't help, but once setup it should be fine afterwards.
I had the LG G Watch R (w/ 420MAH) prior and setting up took a good deal of the battery but at EOD was at 65%, while the Style is at 40%.....understandable given the size of the battery.
I found mine was going dead by mid afternoon with little use.
I found turning auto screen brightness off and just leaving it on 4 helps. Also think after a couple of weeks use it's got better anyway. Usually on about 40-50% by the time I leave work.
Main problem I have is the little dial on the side is in a crop place, so my hand keeps pressing it an making assistant listen, eating up battery.
Really wish there was a screen rotation option so I could wear the watch with the dial on the opposite side.
Oh well!
I would like to see more options for ambient mode. I think the brightness is too high. I've only found one watchface that lets you control the color in ambient mode. It's called "line". I changed the ambient color to just red and decreased the opacity of the lines and complications. I've been off the charger for about an hour, received a few notifications and I'm still @ 99%. Might be a fluke, but I'm sure using a single color uses less battery than using white, which is all 3 colors combined.
This is my third smartwatch in 2 weeks. I've downgraded twice because others are just too bulky. I'm sure there's a solution out there. I hope battery life gets better in time with updates. I hate this range anxiety.
I just bought one and it is still too early to tell but battery life is fine for me. If I disable Bluetooth (which I know defeats the purpose of it) and WiFi with no ambient, it lasted me about 2 1/2 days (but I do turn it off at night since I have no need to keep it on while I sleep). If I keep Bluetooth on, no WiFi, and no ambient, it lasts the entire day (13 or 14 hours) with about 40% left. I have to do more testing (especially with ambient). You don't want the watch face on all the time anyway because it will cause screen burn-in. Some of the watch face apps allow you to use an ambient where it is usually black and white with less information showing.
Hello. Can anyone help with a battery model? Need to search for a replacement one but there is no info at the internet about its battery nor where to buy it....

Same here.
I looked everywhere. My battery is dead, it drops from 100% to around 30% as I disconnect it from the charger.
Even if we find the battery, the replacement looks hard. I was hoping to just get the Pixel Watch but I guess that's not going to happen.
Hi guys. Today I made a short video with opening of this device.
Enjoy.
