[Q] Battery Issue

I've been reading a lot on these forums, and no one has seemed to address ways to improve battery life on the LG Revolution. I just got this phone a week ago and I've been averaging 13 to 14 hours of battery life with moderate to heavy use (applications, e-mail, texting, etc...).
Anyone have any tips or tricks to improve the battery life besides rooting it?
Is it worth rooting it now with Gingerbread rumored on the way?
Thank you all in advance.

personally..GB isnt available with Verizon yet..I would look for any leaks or anything that isnt officially supported..unless you wanna try it..turn BT off..use wifi when you can..turn screen brightness to 50 on the bar..try to look for battery saving apps on the marketplace..just a thought

I just got the Decrapified Rom on mine today, and am seeing some decently better battery life.(i used to get ~12hours anyway with some heavy usage)
Also...when I rooted and customized SetCPU a bit I saw much better battery life. I was able to clock down the CPU when the screens off, or when the battery is low, etc.
Just some thoughts for you

This helps battery life? I always thought wifi drained battery. But your saying wifi drains less battery than 4G? What about 3G?

Check your apps as well. I was watching my battery drop a percentage in literally minutes. I thought it was just the phone, and that I had to live with it, but in my case it was Go Weather!!
This app is EXTREMELY bad - drains battery insanely, and even when you configure it, it keeps popping back up in the running apps and goes to town draining your battery.
Apps like that can make a somewhat average battery life turn into an insanely bad situation.

13 to 14 hours with moderate to heavy use???
I'm lucky to get 10 hours without any use. I let it sit on a table overnight, and the next morning it was down to 28%.

[Q] Major battery drain on MIUI

I'm running an un-modded MIUI ROM from MIUI[dot]us and basically the battery drain is becoming an issue to which I assume its kernel and theme related. Basically has anyone got any suggestions to a compatible battery saving kernel that can aid my issue? Whilst I was on the phone now for 30 minutes it apparently used 40% battery. Thanks for the help in advance

Use the Battery Calibration App from the market. IT wtll fix your battery stats after flashing.

I noticed it too. One week ago I was using gingerbread, which the battery lasted for about 24 hours with the same use as now with MIUI [ICS] 4.0.3 that lasts for about 18 hours.
I calibrated the battery two times, it helped a bit.

[Q] Are the battery drain issues with ICS fixed yet?

Hey there,
In case you can't tell, I'm a newbie.
Anyways, I'm currently using a 6-yo HTC Dopod Pro and I've finally decided to get a new phone.
I really want to get a Galaxy Note but I hear that the Note has a relatively short battery life.
I also heard that ICS for the Note causes the battery to drain even quicker.
Have these issues been fixed yet?
Cheers.

What you have heard is misinformation. A bad installation of ICS, rogue apps and weird settings are the cause of people having battery issues with ICS.
The Note has one of the best battery lifes among all android phones.

Note has excellent battery life. I have the LQ2 ICS, and I have no weird battery drain, wakelocks or any other probs

Just disable some draining apps on ICS.
Don't forget the huge power of note battery( 2500mAh)
I'm also on LQ2 ICS =]

I heard the battery life was pretty good whilst on GB but as soon as people upgrade to ICS, the life was substantially lower.

The battery drain "problem" of the GNote is like troubles with your Windows computer (IMHO): The more you fumble, worse it gets. Use it as it was designed and you'll be a happy person.
I have a GNote for a few months, it was Full Stock under GB and now is Full Stock under ICS. I use it moderately (2nd phone) and could easily manage 36 hours.
I pick it of the charger ~5h30, 6h00 in the morning and find it at 60~70% when I get home about 12 hours later (30~45 minutes talk time, not much else). I than read my favorite blogs and news papers that runs it down to 30-40% (reading takes about 1,5 hours).
When I go to bed it's never lower than 27-30%
The only problem I have is that it sometimes doesn't go in Deep Sleep and that I solve through a systematical reboot in the morning (of the charger).
As always (even people) the GNote is as good as you treat it

Hey Little Vince
Welcome to XDA!
I have had Note for over 6 months (bought from UK to Brissy) Been on ICS only last eight days or so - and I can report that the battery life is slightly better than GB. Speed is better too - not as much lag.
I have used Blackberry/Axim/Palm before and always got into the habit of charging overnight so anything longer than 24 hours doesnt really matter.
Please don't let others put you off a wonderful phone. It is so versatile.
PS - it always takes a few battery cycles (e.g. three or four days) before you get accurate info. I have had quick battery drain for a few hours after updating Kernel but it always settles down.

What is that systematical reboot you're talking about? Can you explain a little bit?

There are a few tricks suggested in this thread http://forum.xda-developers.com/showthread.php?t=1649041
I found my battery life was quite poor at first but it has improved after a few charging cycles. Also, I had a lot of syncing processes running (some duplicating others). Killing some of those also helped.

Never had an issue with batt drain, either on gb or ics... I think the latter is a bit better. I leave gps, wifi and 3g on all the time, and am a relatively heavy user... really haven't tweaked anything for batt life, other than removing some bloat.

OP, it would probably help if you told us what you would consider to be decent battery life. That way, people will be able to tell you if it is possible.
As for me, I'm on CM9 and have never tried stock ICS. I can confirm that battery life was better on GB, but CM9 still gets me through the day on fairly frequent use.
Usually fully charged when I get up in the morning (6am), and down to about 20-30% when I charge it at night before bed. This will normally include roughly 3-4 hours screen time from watching movies on the train and internet browsing throughout the day.

Same here no battery problem. I'm using DXLP9 firmware.

Nah battery drain is a real issue with ICS. It's too documented to be denied. Doesn't matter what I think is good battery life, but relatively with GB, it was 20-30% for about 12 hours of use (wife doesn't use it much) and after ICS, it's -110%. Hmm.. I meant for the 12 hours, it needs a charge and then some. And that's crazy since my wife really doesn't use it much.
Anyhow, this completely fixed it for me. Looks like there's a few bugs that you can come across if you have battery drain with ICS. Check the full thread for more details...

UPDATE: ok no. Still no real solution for fixing this after trying many over lots of days. AFAIK, kernal problem that Samsung needs to fix. And please do fix!!

As I see it from the times from BBS the problem of the drain is at standby mode where the battery for the start of locking and outing on sleep it eats slot of battery till it reaches the 1% every 1 hour and 45 minutes like it was on lc1 stock, even I had on GB 2 hours 45min for 1%, it starts with 1% for 30 minutes then 45 min 1 hour and so on till it reaches the max of it.
The use with screen on is the same 25% for 1 hour and 20-30 min screen on time with low brightness, as it was with GB. On GB I had 5h30m screen on with 10-14% battery left.
So the issue for me at least, is the standby aka sleep mode.
Sent from my GT-N7000 using Tapatalk 2

to the OP, yes battery drain is a documented issue on ICS, with the wake locks and rogue apps (for the unlucky few.. myself included)
i was on rooted stock GB and i used to have a good 72hrs of standby time for the note especially on the weekend when it is rarely used and maybe a good 48hrs on a weekday with average usage (about an hour's call, moderate surfing, facebook etc)
during days when i travel a lot i can be surfing and listening to music and doing calls for the better part of the day and the note still lasts a day with about 20% juice left by 7-8pm
however after I upgraded to ICS LP9, my battery couldn't even last me for a day without getting a few hours of charge from my laptop, i was on stock ICS for 2 weeks and did a lot of fine tuning just to optimize the battery life and ensure the phone goes into deep sleep and still not sufficient. the thing that blew it for me was when i noticed that my note started running at 1000mhz only and not any lower (even when charging - take note i was on unrooted ICS).. so decided that ICS with all its hype wasn't polished enough yet and was not worth it for me and went back to my stock rooted GB LC2
now i'm a happy camper.. note sleeps like a baby when it is supposed to and runs smoothly when called upon
so to answer your question (sorry about the long story) yes you can enjoy great battery life on note be it GB or ICS but you won't know until you get one for yourself.. and like what the other posters said the note is such a beast of a phone that you will not look into another phone again once you get one be it on GB or ICS

I absolutely would not recommend the G Note until there is another ICS update issued - unless you want to stick to GB (in which case I would definitely recommend).
Apart from the deep sleep problem, which for me anyway, cannot be resolved, I've had stability issues, overheating and it even pulls restarts without warning.
The only battery fixes that have kind of worked for me (and they still don't get me anywhere near the battery life I was getting with GB) involved me following a 5 step programme every time I charge my phone, which is frankly unacceptable.
FYI - I've had the note since December and it's running stock everything.
The Note is an amazing phone, but ICS has rendered mine not fit for purpose.

The sad thing is samsungs and android capabilities in finding the culprits. Fancy native battery charts which dont help much, if any in analyzing.
Only best case is to check deep sleep(cpuspy) , and if deep sleep is low check partial wakelocks in betterbatterystats.
Then you can find a lot of the culprits
Good thing the XDA community picks up where Samsung/google drop the ball.

To the OP. My Note on gingerbread had wonderful battery life 16+ hrs. After the ICS LPY update my note dies after 5 hours. To all the naysayers saying there are no issues with battery life on ICS, give me a break. Just google how many note and galaxy SII users on ICS are having battery drain issues.

I get exactly the same battery life on ics that I did on gb, the battery drain people are having has nothing to do with ics. It will be apps causing the issues. Im running exactly the same apps as I was before and its exactly the same battery.

mmm.... No.... The same apps, even after a factory reset and reinstalling apps I STILL had the drain. You say it's apps that aren't optimized? That could be true... but then again, I guess it must be a VERY VERY common app that's causing this because most everyone says they've experienced a decrease in battery life.

Upgrade your phone OS to v10h, maybe remove bloatware.
Give your batery at least 10 charge cycles to get to its full capacity and to work fine. You can't expect a battery of 2Ah to work out of the box like it should. Also your battery has a 6 months guarantee if it's new.

Connect to wifi and go software update via phone in settings, i think there is an app in lg named software update, too?
If you can't the normal way then, find how to flash your phine with kdz in android development section or general.

[Q] Battery life

Hello everyone,
I wonder how much battery life you have on i9000 with stock battery (1500mHa) on cm 10.1 with semaphore kernel?
Asking, just because I can only get max. 12h of battery life with cm 10.1 20130218 rom and semaphore 2.9.10, smartassv2 and row. Wondering is this normal or my battery needs to be changed. Any suggestions to max battery life on i9000 would be appreciated too
Sent from my GT-I9000 using xda app-developers app

The battery can last between 3hours and a week, depending on how you use your phone, so that's not a good question to ask.
If you feel that the battery is running out too quickly then download betterbatterystats and look for any apps using unusually high partial wakelocks or alarms and get rid of them. It only takes 1 rogue app to screw up your battery life.
Sent from my GT-I9000 using Tapatalk 2

I think he knows that.
12 hours uptime is not uncommon, especially when on 3g a lot. On wifi you should be able to get at least 20 h in my experience. If the battery is as old as your phone I suppose its capacity is not what it used to be, and you might consider replacing it with a sgs+ one f.i. - they come cheap nowaways!

That's in your experience, the way you use your phone.
Try playing NFS MW or something. You'll get about 2 hours on a gti9000. It varies far too much to try and tell people how many hours battery life they should be getting. Totally depends.

I use my phone for 3h wifi browsing, 30 min. music and 30 min gaming, but nothing intense. And with this usage I get 12h battery life. Flashed 2.3.5 stock rom. Still getting 18h max. So I think this comes to conclusion that my battery is old enough. That's why I asked for the battery life you get, because I didnt knew this is usual or not

My last for 2 days more or less depending on usage.

AW: [Q] Battery life
Guys i think its wrong to measure the battery life with how long your phone is working. i personally look at the screen on time it says more than just how long our device is working. I get always stats around 3h its unimportant if my Phone works 6h or 18h.
