JuiceDefender (or similar?)

Two questions:
1) How does the JuiceDefender widget calculate its savings? No WAY it is giving me 3x battery life (which it says at its peak) or even 1.4x (which it says at the lowest)?
2) Are there any similar apps that you guys use to save battery life that still allow for scheduled activating of APN/WiFi so I can get my e-mail/updates/etc.
Thanks!

anyone?

I was gonna say you could just use the Juice Defender widget, which allows you to switch off your APN at will. I use it, quite a nice little widget..

if you use ultimate juice with juice defender, you can set it to more than 1min every 15 (when apn enabled during time phone is sleep). I have mine set for 5 min every 15, and I'm not seeing any email issues. My N1 went from 7hrs battery life with heavy usage (text, twitter, browsing n a couple calls here n there) to 13 solid since using.

I have to agree with 5 minutes ever 15 as the key. I now get my email just fine, and this thing seriously saves battery life. 300% sounds a bit silly, but 1.5x is definitely in the realm of possibility. Eitherway a worthwhile app

Agreed but I'm confused as to why it is so inaccurate.

I got ultimate juice but it is not letting me get to 5 min for every 15, is there something I am supposed to do differently? It will only let me do 5min for every 30

The free version allows you to switch it to 3 minutes every 15 which is adaquate for me to reliably get gmail and two pops. I have used it on stock, cm and enomther and in all cases it gave me a small but noticable gain on battery life.

It might not be inaccurate. It's just how the dev calculates that multiplier.

2.3.6 Kills the battery

Have not got around to calling samsung yet after complaining, but find that the battery dies a lot faster than before. I recently uninstalled juice defender to test and will reinstall under the new os to see if that had a effect. Any any ideas or clues to fix it?
Thanks

Did you re-calibrate your battery after the flash? Usually a good ideal, and it usually takes a few days for the took to settle in.

pretty misleading title.. 2.3.6 has been a big jump up from the older leaks for me. To each their own. I would re-calibrate.

2.3.6 had given me great battery life. I would definitely calibrate your battery either through CWM or the battery calibration app. Almost always after a new flash my battery is horrible until I calibrate.
Another thing may be... I previously had Juice Defender in the past. I found that it seemed to kill my battery faster than without it. The way the android operating system is set it automatically helps save your battery life. Most running applications get moved to the background and are using very close to 0 battery. For anything that I do not want running constantly I use titanium backup and freeze. It works flawlessly.
I do not use anything such as juice defender or auto task killer and get about 44 hours out of my phone overclocked to 1.3 with moderate to high use. Let android do its thing and you will be better off IMO.

Juice defender does help when setup properly. I've gotten over 100 hours of battery life using JD - though I'm still on 2.3.5

Check your battery stats to see if there are any unnecessary programs or tasks that are killing your battery life by running all of the time. Something that you may have had set-up or syncing differently since you updated.
2.3.6 has been giving me great battery life, I am running stock KJ6 with KJ6 Voodoo-kernel, no UV or OC, no "battery saving apps" and I'm getting 12 to 14 hours with heavy use, 30+ hours with light use.
Check this post

And the link on it...it explains how the SGS4G will automatically calibrate the battery under certain conditions, and how to go about it.

I never had a problem with the battery life before. On froyo it usually lasted all day with about 50% left.
On kj6 it lasts all day and about 70% is left at night.
I have no task managers installed and syncing with google, exchange, facebook, weather and couple other services.

How many here use Bluetooth? I usually use it quite a bit, but noticed that the new official kj6 uses an unusual amount of Bluetooth share (my battery life has dropped dramatically as a result).

I'm currently at 66 hours with 24% battery left. probably won't make it to 100 (4 days+) on this charge, but I have on more than one occasion.
I am a light user though, only some wifi browsing and wifi calling, along with regular calls, and maybe checking traffic every once in a while. I don't really use my phone for games or music.

Battery Usage

Sup guys,
I was curious to know while actually using your charge how fast does your device drain the battery. I know it can vary depending on what your doing (video streaming etc) but lets use web browsing as a example. Looks like I lose 1 percent every 3 mins. Does this sound normal?

Last time I tried that it messed with my data connection and completely killed it to the point of wiping data...

You should be able to get 2-3hrs of screen on time per charge cycle. This is also dependent on what you are doing when the screen is on, and also how much your phone is doing with the screen off as well.

Which thing messed with ur data? The battery saver? I had that problem with other battery savers (juice defender, battery doctor) but no problem at all with AnTutus battery saver.

I go 100MHz-800MHz conservative, and almost all my apps run smoothly. If something like an intensive game needs more juice i go 1.2GHz and smartassv2. Ondemand is junk don't use it.
EDIT: I just went 12 hours 29 mins from full to completely dead (powered off) with 2 hours 23 mins of screen on, much of that was heavy web browsing (lots of tabs on Opera) and gaming.

going to try your setup. Any minor synchronized apps? Like weather for example.
Sent from my SCH-I510 using XDA

Interesting. I run TS1.4 w/ PBJ (no ext4) and I went through a number of settings and I could not get sav2 or sio to be lag free. The combination of ondemand and noop yields the best performance for me. Now if I happen to have 5 or more apps going then RAM becomes and issue and I have to march out w/ task killer.
I also 100/1200 for CPU settings, no volt modification.
Up until the latest google maps update last weekend, I have the sensor thingy killing my battery every few days, and that has seemed to clear up.
I also bought one of those extended batteries from ebay w/ 3500Mah and it is a beast (last 1.5 days easy), however a bad result of that is that it interferes w/ the BT and Wifi reception to the tune of -20db so it makes a marginal connection crap. It looks like the charge antenna is on the right, right next to the battery, and the beast sticking out is messing w/ the signal. I am going to try a few different materials over the battery to see if I can sort it out.
It is almost fearsome how quickly the stock battery drains...I mean if I am out work and going out until 3AM, no way it will last unless I use the beast.

Weather Channel, turned sync as low as possible to the point where there is nothing in my status bar and I go into the app to check it.
Friendcaster set on 1 hour updates.
Also no latitude!! Make sure you are signed out of latitude in Maps and never open that app. It updates your location to google which wakes the phone and stuff.

[Q] help with my battery performance?

Can anyone look at these screenshots and advise me on how I can get better performance from my battery? I just flashed SkyICS (latest version) hoping to get better performance from my battery, but it doesn't seem to help. This is with what I would consider medium to heavy usage. I used my phone most of the day to browse the web and check facebook.
Any ideas?

I prefer no frills cpu. It will report the wrong settings when the toast pops up, but if you check cpu spy you will see it's working

Here's a couple basic and obvious tips and you might already know this, but no one has mentioned it yet in this thread so...
Turn wifi off when there are no wifi networks to join, but I've heard not to let it sleep when you are wifi connected.
Leave bluetooth and gps off when not using it. I don't let allow any of google's location services to run in the background myself. Not sure how well that helps the battery though.
Some people say leaving off autobrightness turned off will help battery life and some say leaving it turned on is better for battery performance. I'm not sure who is right but you might try it both ways and see if one is better for you.

I've tried most of those things and they don't seem to help.
I'm in an area with lte but coverage is spotty at work. Could that be what is mainly killing the battery?

Sounds about right for me then. There is definitely some battery capacity loss as it drains a bit faster than a year ago.
i leave LTE on at all times, brightness between low and auto, and my total screen time will be around 1.5-2 hours max.

the only way to get above 2 hours onscreen time is to heavily under volt, -75mV or above if u can. if you aren't already, you're missing out. Battery gains for no performance loss.

super lite is a good, stable ROM, no bells and whistles, only what u need for a dd. lightning kernel is stable, and I recommend either voltage control or incredicontrol.

Im using Mohans latest Embryo 6.1 and tried both of the voltage controls you referred to and incdredicontrol gave me messages that stated there was a conflict with the kernel. I Installed voltage control but it appears the minimum I can set it is 192 mhz which is the same settings in the performance tweeks portion of the rom. I read earlier that it could be taken as low as 75. Any idea what I might be overlooking.
