For those of you unfamiliar, JuiceDefender is a tool which toggles WiFi and Data when the phone is off, and turns on WiFi only when in a location where there's an accessible network. This software more than doubled my battery life on my Bionic, and so it was one of the first things installed on my phone.
I've noticed JuiceDefender has been sucking a fair amount of battery on ICS/GNex (usually 4% in the battery graph), so today, for an experiment, I uninstalled it for the day, and I've noticed that I've gotten better battery life than I ever have with the phone, across a mix of WiFi areas and 3G.
Has anybody else had this experience, or was this just an odd one-off situation? Could there have been a change in ICS which diminishes the need or hurts the usefulness of it?
I've had JuiceDefender off too and for me I seem to get slightly worse battery without JuiceDefender. Without JuiceDefender on I tend to get a steeper battery drain during idle times compared to leaving wifi and 3G on. I think the usefulness of it depends a lot on your usage habit and signal quality as well. I usually get spotty signals so that is probably why JD helps noticeably.
Interestingly though if you take a look at the battery graph in settings, every time JD toggles your data on it seems to force the phone into awake state, but just leaving data on would keep the phone in an idle state most of the time. That's definitely something that is making JD not as good as if should be.

Honestly I think the only time you get noticeable battery improvements with juice defender is with periods of no use. Which is why it works good for me, on work days that is

Totally agree with this.
That's odd, as for me, the phone is mostly in my pocket all day. Maybe it's because I've got a 15 minute synchronization time for most things?
Day three without JD, still getting twice the battery life that I was getting with it on. Delightful.
I don't like any Kind of app that claims IT saves battery life because it just doesn't work! Fact is that its just another apps that sucks resources out of your phone!

Going to have to disagree and while there are many variables juicedefender can offer big saves depending on your usage. I have had 1.6x increase as stated in the app and confirmed by the extra hours with the incredible. I am waiting to try it with the GN until I have a idea what battery life is without it. First week is useless anyways with a new device as you check it more often and the OS is still refining the battery meter.
Its all related to how you use your phone. Disabling Wifi, Data, BT and so on automatically, managing autosync saves battery. The app itself sucks almost no battery power - if i can believe my monitoring app (SystemPanel 1.1.1) which i use unfrequently to control app behaviour on my Galaxy S1 (with ICS and before that, on GB). Im taking up this "Old" posting because i have battery issues on ICS - almost half of the lifetime after upgrading from GB. But i think its because im now more playing around with the phone, no app is sucking more power than usual.
I noticed that JD cant control networking (via apn change) anymore, can somebody confirm that? If i turn the display on, my 3G/HSDPA connection is there - under GB it took 3-5 seconds until i had internet connectivity back.
I have a launch day Evo and love it to death.
I'm a smartphone veteran so I have no problems with poor battery life. It comes with the territory.
Problem I'm having is that I have the worst battery life of the 9 Evo's in my circle of friends.
I'm going through 3 batteries a day (I do not charge in the car) and sometimes even need a 4th just before bed.
How can I determine if my phone is defective and killing my batteries?
Just noticed the horrible subject wording. Can the title be edited?
Have you tried calibrating your battery.

Well we need more information. What do you use your phone for, how often, how many texts/emails/calls a day, are you rooted, what do you have syncing and how often, etc. But yes, going through 3 batteries a day is not normal. You can use an app like System Panel to see what apps are using your battery all day.
You guys are fast! Thanks
OK, a litlle more info:
1. I'm rooted, using Synergy ROM
2. I do text a lot during the day, use bluetooth when driving between appointments then turn it off when I arrive, browse occasionally, and talk on the phone very little
3. I have calibrated my batterries before and am using new batteries I only just got a few months ago
4. I once read some negative info about task killers that scared me to death so I haven't used anything like that
5 I put "Battery Monitor" on my phone a few months ago but have no idea how to use it or what it does
When I was using synergy my battery used to drain fast. Did you turn off compatibility mode in spare parts? Turn off some auto sync apps. Disable vibration. And automatic brightness option

I wonder if its the ROM itself
I completely removed spare parts because I didn't understand what it was supposed to do
When running a custom rom, you can always run into problems like that. Personally, I had pretty weak battery life with Synergy, not as bad as you, but worse than other roms. Try flashing MikG, it's basically the exact same rom, but smoother and better battery life.
Hi,
I have a GN extended battery, and I've noticed it's been draining much faster as of late. I used to get 2 hrs of screen time, now I get just over an hour. I'm thinking this is the battery itself, since I've switched kernels and ROMs several times, with the same result.
Is there any way to test the battery for quality? Other than my subjective opinion that it seems to be draining faster, is there a reliable way to test whether its lost its ability to properly drain?
Flash Stock Rom and enable automatic brightness. If you can get 3 hrs of screen on time everything is normal.

I've read a lot of posts complaining about battery life, and other posts about users suggesting ways to improve battery life. I've read stuff like, disable LED, haptic feedback, lower volume, lower brightness, LTE turned off, underclocking, turning off sync, live wallpapers, etc, etc. To me a lot of people are crippling their phones. If your battery can last you 10 hours, that's enough because you'll probably be somewhere you can plug in. What's the point of being able to go for 20 hours when you'll probably have the opportunity to charge it before then? It's better to have and enjoy all the features.
Maybe somebody can chime in and give me their point of view.

I agree. I would never want to sacrifice a feature just to extend the phone's battery life. Instead I use a custom rom that has all the features (and more) and 12 to 18 hours of battery life.

Part of the issue is a sociological thinking pattern between wanting "more" and needing it. Depending upon the type of lifestyle you live, sometimes, battery life is of dire importance to have if you're constantly migrating around. But I agree, some people who aren't in that sort of disposition go overboard with it.
I just bought a bigger battery :good:
I agree wholeheartedly. If your battery is lasting you through your day (which mine does, and more) then why try to conserve it?
Yea its funny stuff people complain their battery only lasts 20 hrs but yet they want it to be able to do everything a computer can do and more....

The only conscious effort i made to extend my battery life was to undervolt the CPU a bit, but this was more for the lower temperature advantages with extra battery life being an added bonus. Beyond that i turned off things i dont use like BT, no need having something running that i have no use for. Overall i was happy with the stock battery except for any kind of heavy video or game usage which drains it pretty quick - solution : bigger F'n battery :highfive:
i agree that some people seem a bit obsessive about it. but we shouldn give bad battery life a pass either. hopefully we will see some sort of advancement in batteries to have better battery life while keeping them at a decent size.
i was kinda worried id have horrible battery life with the S3 being that its LTE. my last LTE phone was so bad it would die after 8 hours idle.

I keep the brightness to the lowest setting anyway, but I do all of this because I go to school fairly far from my home, and I'd like to be able to play games on my phone without wasting 5% battery every 15 minutes. I haven't switched power saving off since I bought the phone.
Stock ICS on my S3
I bought the extended battery because I like playing games from time to time and I don't want tl have to worry about my phone dropping 15% after playing something for 5 minutes. Like someone else said earlier. It really depends on the kind of lifestyle you live. I for one don't mind having the extended battery on my phone but I do miss how light it used to be.

How heavy is it? Does it fit in a case?
For me, and I want as much battery life as possible to avoid those situations where there is no way to charge you phone even if that only happens 1 a month or less.. As a parent I can't just let my phone die on me... I always need enough to be able to take or make that important calls/text. My goal is to have at least 20-30 hours of battery life per charge.
I think the only major feature I've given up is live wall paper. Other then that, it is just disabling other unused apps like gtalk, talkback, Google bookmarked sync. As well I've uv my phone as much as I can and run a 1350 max clock speed. I really don't see any major dip in performance as long as you do it right . I do use Tasker to disable syncing globally when the screen is off and make sure it automatically disable bluetooth after 10 mins once it disconnect. Also I have the Y5 app to automatically toggle wifi based off my network location. The most useful battery saver I've found is to set my wifi to only connect when the screen is on. Seems kind of backwards but it works well when very little data is process during idle rather the the phone requiring to keep a constant connection to wifi.

I'm also one of those people that closes an app as soon as I'm done with it. Use an app, press the home button, release and hold home, swipe the app away, sigh in relief. An old habit carried from my S2 Skyrocket, where getting 8 hours on stock was above average.

I have my screen brightness at 40-50 auto off.. i cant imagine turning it all the way down like alot of people say.. even when auto brightness is on it look very dull and dark at night to me.. Same thing for my tv with auto brightness.. but i still get good battery life. I am fully charged at about 6pm i use it till bedtime and use it for my alarm.. get up 4 am and when i get home at 2pm its still over 40%.. only thing i do is close all my running apps by holding home button a few times a day and same with ram
I work in an office so it's plugged in for the 2 hours before I leave so I have everything on full most of the day (brightness, lte...). Also, by undervolting I'm getting 30% more battery.
I think tips on increasing battery life like turning off lte and brightness are for people who can't plug in throughout the day or for emergency situations when you want to get the most out of your phone because there's some reason you can't charge.

I get anywhere from 12 - 23 hours depending on whether I'm at work or off. I can live with that...but there are situations where being unreachable poses a problem.
So, to deal with my phone addiction, I got an original replacement battery. Always have it charged and on me. When the phone shuts down, pop in the replacement and your done. About a minute without a phone. This way I don't have to UV, worry about brightness, WiFi, Bluetooth, etc...
I can't deal with the bulk of an extended battery.

30% more battery by simply undervolting? I think that's quite an overstretched statement. How is that even possible?

Its not possible. Not by solely UVing. The sole purpose of undervolting is so that your phone dosent overheat when running high clock speeds. Saving battery is just a perk. You might save a few percent with the undervolt but nowhere around 30%. But don't take my word for it.....

Hi
I've been playing around with my note for a while and noticed that my old ipad 3 has a lot better standby time compared to the note. Now granted I use the note more often and it checks mail and diff accounts more often then the ipad , but we're still talking of a 3-4 day difference.
So I was wondering what's the best way to test batterylife on the note? Any app that can test it easily ?
Been playing with settings and even ran it on power savings mode for a while, but still feel that the battery drains a tad faster then it should
Suggestions?

What does it do? test or improve the battery?
It shows you exactly whats using your battery and wake locks so you can see whats waking your tab and draining your battery

Decided to check drain overnight . did a full charge and left it overnight + part of the day. Didn't touch it, look at it or think about it , check after 14 hours battery down to 80 % Android system seems to be eating alot, best way to figure out what? Screen wasn't used at all
Wifi was on, everything else off, and battery savings was on.
