JuiceDefender: What are your settings? - T-Mobile Samsung Galaxy S II SGH-T989

Just wondering what those of you who have good battery life and are using JuiceDefender have it set to? I am getting horrible battery life and I've followed the battery thread and tweaked around many things.

[Q] Battery Life - Stock vs Custom ROM

I'd like to hear some experiences that everyone is having on how the battery life is on the stock ROM (POST OTA, NOT OVERCLOCKED) vs custom ROMs (Again, NOT overclocked).
I've tried the Virtuous ROM, and as expected the battery life got slurped down like coca-cola! CM6.1 isn't as bad, but still seems to suck the life out of the battery quite a bit faster than stock.
Is everyone seeing similar? What makes the stock ROM so much better on the battery?
My experience was actually quite the opposite. When I switched to CM, my battery life improved by about 20-25%. I have a NAM Desire Z so it was running HTC Sense over Froyo.
Remember that it takes a few days of usage for your battery to 'calibrate' itself to the new ROM. My first two days on CM were really bad, but since then, battery life has improved greatly. Yesterday, after moderate use and 15 hours, I still had 45% of my battery left. With my stock ROM, I would be lucky to get 15 hours of use out of the phone period.
As far as overclocking goes, I haven't seen much of a difference in battery life. Reason is, even though you are overclocked when the screen is on, you can adjust settings to under-clock at other times, saving battery power.
I would recommend trying a Custom ROM for 4-5 days, that will give you a better idea about its battery life. Also, there are lots of settings you can tweak that affect battery life greatly. Widgets, background data, signal strength... SOO many variables in personal usage that battery life is going to fluctuate user to user regardless.

[Q] Battery Life

Hola
I looked around and didn't see any threads dedicated to this, so I hope it's not a duplicate.
After rooting and doing the ad-hoc wifi patch, the battery life is one of my few remaining complaints about the a100
Some of the reviews that I've read (for other devices that have received a stock ICS update) have mentioned noticeably improved battery life. I was wondering if anybody who's tried out any of the leaked updates has noticed an improvement and if so, you wouldn't mind sharing some stats to give the rest of us an idea of what to expect.
I noticed an improvement in battery life by quite a bit, after upgrading to ICS, but as with a lot of things battery life is subjective. Spend all day gaming and your battery life will take a massive hammering. I don't game a lot on mine but I use it like a laptop and I guess I get a decent day out of it with full brightness and a fair bit of YouTube
There's so,e tweaks to the build.prop on ICS that add some helpings to the battery life, also if you're rooted you can use setCPU etc to lower the screen off CPU freq thus saving battery there

I haven't really noticed any huge difference in battery life when it comes to heavy usage. I get around 4 - 4.5 hours of gaming at medium low brightness. I think with the custom build prop I get more standby time and more battery life for light usage on wifi, however, I find the best way to get the most out of my battery is use airplane mode for gaming and readding.
I noticed battery management changes in general. It seems more efficient at conservation. It also shows you what apps are consuming your battery in settings now.
Thanks for the feedback. Now that I've read that the devs are working on a CM9 release, I'm totally willing to wait to see what goodness they have in store for us!

Making sense of Bettery Battery Stats

Any tips on how I can improve my battery life through this program? I've been running Better battery stats for a couple of weeks.

[Q] Battery life

Hello.
I was wondering if my battery life is low or not, so I want to know what your battery life is guyz.
My battery would last like 12hs with wifi always on and facebook, some music here and then and youtube. is it a normal consumption ?
There are so many variables that come into play with battery life that is nearly impossible to quantify what sort of battery life someone should be getting. Screen on time, brightness settings, radios used, reception, usage patterns, apps running in the background....tons of things that will be different from person to person. Also, the actual battery itself comes into play with how well it can hold a charge.
As long as you are happy with your battery situation, all is well. If not, perhaps look into what is using your battery. Better Battery Stats can potentially help you narrow down where things on the software end are draining your battery.

That's about what I use to get.
I went out and bought a spare battery. I'm not a fan of extended batteries so I went with a standard battery for about $10.
I also flashed a new kernel that will help on the screen brightness and underclocking.

[Q] Cyanogenmod or Android Revolution 6 in terms of battery life

What would be the best ROM for battery life? I'm using CyanogenMod atm and the battery life is decent. If I flash Android Rev. would I sacrifice battery life and if so by how much?

Battery usage is completely subjective so what will be awesome for one may be absolute crap to another. Only way you'll know is to try it yourself

As mentioned, battery life is completely up to your usage. Some steps to try though which can be used across any rom is to give Rom Cleaner a shot and to use Greenify. This will rid any rom of bloat that could be sucking up battery and better allow the device to enter deep sleep where the real battery savings are had.
A well optimized kernel would give you some savings as well. I can personally say that on ARHD 5.5 with Elemental kernel .15 I'm seeing about 70% battery left at the end of a normal day. For me though that may only be one 20 minute call and an hour of screen on time. Even when flashing and messing with tons of settings for hours, the phone has never reached a critical battery level for me. I
It's more about the way you optimize (or debloat) your phone , than the ROM you are running. Use battery monitors like GSam or Battery Drain Analyzer and freeze apps that are causing you huge drain. Greenify is also good. Ideally on the M8 you can expect around 6 hours of screen time if you're optimized correctly.

This. I am able to get about 6 hours on stock, ARHD and Insertcoin. With power saver on, that ends up around 7-8 hours of screen time. Coming from a Nexus 5 that got 4 hours typically, I'm pretty satisfied. I'm inclined to believe ARHD will get "slightly" better battery life than CM since it is based off the stock ROM on the M8.
Generally the OEM skinned roms have better battery life and benchmark scores opposed to aosp. Happens all the time on Sammy phones and HTC apparently too. Posts above mine cover most you'll need to know. Its all about optimization and frankly that part is extremely fun and especially rewarding IMO. Gives me an idea for something like a community made thread on different battery tweaks/voltages :good:

Thanks for all the feedback guys
I'm currently using Android Rev. 6.1 odexed (using ART atm) with ElementalX 0.10. I don't know if this is a placebo effect or not, but after flashing ElementalX(with default settings) my battery life seems worse :/
