Save battery?

How do you guys save battery on your lg revolution? I have LTE switch to turn on only 3g to save battery but what are your guys tips for saving battery?

I use JuiceDefender.

My battery lasts 8-12 hours depending on how bad I beat on it.
My active days, I listen to music, play suduko, check xda, play in the market. Listen to tune in radio.
That said. I don't know if that is short. I think it's pretty long, and am happy with it. I have the decrapified rom, love it. I have App Killer by Rechild set on a widget. So I go in set what I want it to regularly kill, and tap the widget through out the day. It's mostly my android process that hogs the battery according to widgetsoid.

does juicedefender help a lot?
12 hours seems like a long day and good amount of hours. i hear task killers are bad for your phone though

I was averaging 9-12 hours with decrapified 1.1 depending on use. JuiceDefender extended that another 1-2 hours but added 4-6 seconds before I get 4G back when the device "wakes up". It turns the radio off and I have it set to ping instead of constantly syncing. 3G comes on 1st, then 4G...

Sounds ridiculous but i turn airplane mode on when i'm not using the phone. Turn it off every couple hrs to see if i got any emails or texts or something. Huge battery savings. I have the accurate battery mod posted in the dev forum so if i wake it up after sitting for an hr it's down 5% if i leave airplane mode off, but if i turn it on, it's down like 1%... maybe.
Once cm7 is available, we will see huge battery improvements, i have no doubt. Gingerbread is much better w/ the battery than Froyo. I saw huge improvements between cm6 and cm7 nightlies on my droid, to the tune of 200% standby improvements. Still heavy use i wouldn't expect more than 15 hrs, but imo 10 hrs is ridiculous. There's not really a huge difference between heavy and light use in battery time either.

good to know! thanks. when is cm7 available for the revo?

Thecubed is currently working on it.

Buy an extra battery and wall charger off eBay... Throw the battery in your back pocket, and you're set all day. I swap the battery out after about 8 hours (when I get to about 20% battery) and I'm good the rest of the day. I've had to do this with EVERY Android phone I've purchased. The OG Droid would only get me about 10 hours right when I got it, but Undervoltage Kernels, and decent Rom's brought it up to around 16 hours on the standard battery. The Samsung Fascinate was horrible - Roughly 6-7 hours out of the box. Rom's got it up to around 12. The Droid Pro - 8 hours at most on the standard battery, never saw any improvements with my usage. Droid 2 - 10 hours out of the box, but when CM7 came out on it, I was averaging around 16 hours before I got the Revo. The 8 hour battery life didn't surprise me. I kinda expected it, and had already placed my battery/charger order before I went and got the phone. I'm not a fan of extended batteries just because of the extra bulk, plus finding a case w/an extended battery is a PITA. And the 3 minute downtime from a battery swap really isn't that bad (especially if you've ever had a Blackberry).

good information. but i don't feel safe buying one off of ebay because i don't think the volts will match and it will have bad results on the phone. i can't find a cheap yet any case for the extended battery. i'm sure CM7 on the revo will help the battery a lot. we just have to wait now...

Agreed, I don't buy from overseas with the battery but the charger really doesn't matter. I got a genuine LG battery for $19 and then just a generic charger for it for $8. Knock on wood I haven't had any problems with the chargers I've gotten, but I don't trust generic batteries either.

Battery use

Can somebody help me out here? My battery life is really bad, today I lost about 10% battery indicator 4 hours with the phone lying in my pocket! When I use the phone its even worse. I am on cm7 nightly 09302011, and it seems like everyone brags about the battery life, just not me. 3g always on, bluetooth off, background data on, autosync off, no live wallpaper and å clock widget. What could be wrong?

Are you using a custom Kernel? Since installing the NeoBlaze kernel my phone has started using power on idle.. last night it used 40% charge while completely idle and not in use..
I don't really care because I carry 2 batteries around with me at all times, but it does seem changing around roms/kernels messes with battery life. Perhaps you just need to hit up eBay, batteries can be had for $2.80 shipped.

Without Juicedefender, 10% in 4 hours with no use is actually pretty good for this phone.. I'm jealous. I get that kind of battery life with data OFF most of the time.

No custom kernel. Thought I read in the forum that ppl got like 3% loss overnight. Maybe thats without data...

get widgetsoid and turn your data on and off (and 2g/3g) on and off quick and easy.
who on earth needs data running over night anyway ?
same as watching full hd videos on 480x800 screen..... thats just dumb

I think this would explain why

I guess 3g is the sinner. Installed JUiceDefender and went from 11h to 32h battery life.

Not sure what happened to my phone, I'm getting 4 hours off a charge now with relatively light use.. just some web browsing and screen off idle half the time.. Going to try topogigi rom and see what happens.

Me too

Battery power for LG Optimus 2x

Hello all!
I am new to the forum so I hope make it without any errors.
I bought the Optimus 2x cellphone last week whith the hope of getting the good one (the one without freezes and black screens) fortunately the cell worked very nicely. I updated to gingerbread and I feel it very good. But I have the good known problem of battery consumption.
Now I have a battery related question. After the update I charged the phone and get the battery indicator stuck at 100% I rooted the phone, installed Battery Calibration and calibrated the phone (left the battery to reach 0% then fully charged to 100% hit calibrate and left the telephone fully discharge again)
The issue is that when the thelephone was at 100% the voltage indicator of the battery calibration was in 4100 mV and here comes the weird thing. When reached 0% the voltage indicator was saying 2000mV.
My question is if this values are right. Someone with good battery duration and the Battery calibration installed could tell me the correct values? I thought that the phone shut down when battery was down to 0 mV but maybe the problem is that my battery is just using "half" battery.
Sorry for my english. I am not native english speaker.
Any help will be highly appreciated.
Thanks

That is voltage, 3300mv = 3.3 volts.
Fully charged the battery would be at 4180mv, fully discharged is around 3200mv usually, or a bit higher.
The phone shuts off when the battery gets below the usable range, which I believe is slightly above 3000mv.
So yes a range of 3.3 to 4.2 volts is perfectly normal for a 3.7v battery.

Hi! Thanks for your reply. So I think I should get used to it. My battery doesnt last more than 12 hours of my regular use. A some internet browsing and some messaging. No music, videos, or games.
Someone recommends the extended batteries of 3500 mAh for this phone? That will make the phone last more time?
Thanks in advance!

Hi Reaper511989, I have bought an extended battery from HERE. It is fatter, but not ugly. And the battery lasts a lot longer. I use it when I'm travelling. I have no idea where in the world you are, but the battery was from a company in the UK.
Have fun. Anil

Huge Battery drain on DjangoManouche/Guestekrnl
Hi,
I was on CM7 kang of temasek and I decided to flash a stockbased rom.
Now I'm on :
DjangoManouche 1.2 rom
Guestekrnl V1.6.1
BB V20Q with ril
I am using Go launcher which comes with the rom
The battery drain is incredibly huge, 8 hours tops with very little use
Anybody some ideas ?

your lucky. i get 6. if im playing 3 albums of mp3's during work. nothing on. just 2g.
imagine if i turned on gps,wireless,bt 3g/4g ahhhh . (cant use fone how its sposed to be used) have ot turn it DOWN a notch. its to HUNGRY on juice. seriously lookin @ one of those MUGEN batteries.

6 hours is just wrong... in the most intense usage you should get 2 hours of screen ON time.. Wifi with 2g on trolling forums with browser/tapatalk should be 4 hrs.

6hours listening to music is pretty normal. If you want longer battery live, stop using the device.

Well in that case you might wanna repair your device since you seem to have the same issue with all roms. That should not be the case that it uses the same amount of battery without using it, especially if no app is loading the cpu....

well actually. cm7 i got about 5-6 hours batt life, cm9 i got no more than 8, GB (stock rom) can usually go from 5-8 hours. but with no bugs. so i am back on GB.
so i dont think device is broken/dodgy since the batt life fluctuates a little. depending on the rom.
my main issue is, ive been reading about ppl using froyo and going to GB and having mass battery drain. now im thinking about going to froyo.

[Q] Bad Battery Life?

Is the O4X's battery life as bad as gsmarena is saying? Just a little over 4 hours of video playback and 4 hours of web browsing?

If you read the comments of the blog article on it, you will see that there is a lot of discussion over the brightness.
By comparison to the SGS3 and One X, the Optiums has a much brighter screen which will mean a lower battery life. Of course if they set all the phones to the same actual brightness (not percentage) the numbers would be different.
I am currently waiting delivery of my 4X, but after I have conditioned the battery (let the handset configure itself to the battery), I'll definitely be seeing what its capable of.

Alright thanks, I hope you'll be able to get back to this thread when you find out more.

I've had mine since friday and I think I've charged it about 3 or 4 times now and the battery life is getting better. It lasted only about 2 hours when I first charged it and started it for the first time. But I was using it constantly.
Today I started it in the morning (fully charged) before going to work and now, 10 pm, it's been on for about 16 hours and I have 40% left. Data have been on all day and I've been signed in to Google Talk all day, I've browsed the web for a total of aprox. 1 hour, used the camera, tested the GPS and been chatting with a friend on talk. So I'm pretty satisfied so far.
It's better than my O2X.

That's good to hear. How many hours was the screen on?

I'm not sure unfortunately. But i would say between 2-4 hours.
Edit: okay it was a little less than I thought. The. Battery usage in settings says the screen have been on for two and a half hours. And that's including the time I have used after 40%. I'm down to 25% now.

My Battery lasts after a few cycles all over two Days with medium Usage (No gaming - WA, FB, eMail)........

i ca go for 1 day, with a bit gaming and usual use.

I have slightly longer battery life on my 4X HD than on my Nexus S when using the phones in the same way (casual use). But I think there is room for improvment on the battery life with more optimized software either from LG or when we start seeing custom roms for this device.

I charged mine to 100% and just dropped 8% in 25 minutes, 20 minutes of that was driving and not using the phone, no Bluetooth or anything like that. The battery life is shocking and can't wait for extended ones to become available. Besides that I truly love this phone

How many complete charge cycles have you done?
Sent from my LG-P880 using xda app-developers app

When I got my p880 I did 3 battery cycles, and I could only get about 8 hours of standby alone, no other use at all. I then did a factory reset and formatting of the memory card, which I hadn't done when I switched from my old SE X8. Now my p880 can easily go more than a day with some gaming, calls, browsing etc. My guess is that old android files on the memory card was the reason for the bad battery life. No expert though, maybe someone else has a better idea.
Today I tried the Chrome browser, and it really drained the battery. Something like 20% after browsing for 15 mins. Anybody else have experience with this?
Overall I'm really happy with this phone, great screen, fluid operation, good battery.

I've had battery drainage issues with the chrome browser as well. Even in stand-by the browser would drain the battery. It has only happened like two times for me in the four weeks i've had the phone, so not a biggy but still something you should be aware of, if you experience battery drainage issues

Mine is better
With moderate use* I went from 18 to 22 hours. I am happy...
* My N7 is not my daily driver, my pc still is... So it sits idle more often than not...

I'm totaly happy with the battery... getting at least a day and a half with normal use.

after updating its definitely drainng fast.

No drain here. I get 10-12 hours a day with heavy use and easily a day with moderate usage. Was roughly the same before update as well.

First of all hello everyone
Yeah I've literally only had my Nexus 7 a matter of a week but I can tell the difference between the battery per and post update. It seems go drain a lot quicker!
Any tips on how to save battery and keep it for as long as possible bar the obvious app killer etc...

If anything, mine has got slightly better. Used to have less than 18% by 8pm, now its more like 25%. I use it pretty much all day for YouTube, Engadget, Flipboard, Tapatalk, Chrome, music and a couple of hours of games.

4326mAh battery, 2A charger, 2.1 hours theoretically. Realistically, 2.5-3.0 if pretty much empty.
If you're using a non standard cable or charger, who knows what the charger is actually outputting. If you're charging from your computer USB Port, that's 500mAh, so 8.6+ hours. Some random phone charger, probably 1000mAh, 4.3+ hours, etc.

The brightness of the display adds to some of the drain I notice, when possible I keep mine somewhat on the dimside, obviously if I'm in an area of bright light and it hard to see then I'll crank up the brightness.

Can't complain about battery usage.. It's amazingly energy efficient even on a stock kernel considering the horsepower this thing has.. I average 20hrs or so with moderate to heavy usage.

I think battery life is pretty good

I've had really bad drains since 4.1.2. I think I've narrowed it down to an issue with Google Play. I've noticed it several times - Very good battery life, but then it will go down fast, even when sitting unused. If I check battery usage, Google Play is always number one with >50% of the use.
If I force close GP, all will be well for about a day, but eventually it happens again.

I also felt it, but only by that much...not too obvious. From full charge, after only night idle, drop 3 percent compare to last time 1 or 2 percent

Hallo!
Same problem, battery drain is faster, with normal use 12 hours (before 17) and when charging phone it's just 99%. With factory reset same resoult. Now I try without all gps conections.
Anyone have good solution?
