Saving battery on froyo

So everyone has read the article about how changing the colour of the screen can save up to 50%. Basically we need like mono colour theme. So what I've done is flash setenza's SETROM as it's black like themed plus my wallpaper is pure black, my Widgets are in a shade of black and I'm using prolauncher which has a lot of black too. Now so far my battery drain is pretty good. Before is was running 64% screen usage now it's 54% I'm yet to test it on a full battery charge coming from a reboot. Also setenza issued a kernel zip for the processor and voltage which seems to working well. Also not using oc uc app seems to be better than using it, there is no need to even overclock it just give about 2mflops more

Cleaning Services starting up would be a good way to save battery too.
Some Apps can do that, but it need R/W access to /system, and most of them are just killing services after os started.
Anyone can point me out a way to edit services and apk startup by recovery mode or adb shell?

And then there is Locale, and Juicedefender.

Good point! I think I'm gonna uninstall all the apps that I rarely use. We have titanium backup so when needed reinstall the app. Until of course we ever get somekind of unlocked bootlaloader.

* DeFrost 1.7c / black taskbar mod.
* Unneeded tasks killed
* Waited for 5 min for essential software to refresh.
* 100% charged before test.
Battery usage/average based on SysFS battery output: lowest to highest
Code:
Screen off (standby): 117mA
Screen home screen / brightness off: 172 mA
Screen home screen / brightness med: 196 mA
Screen home screen / brightness full: 232 mA
Normal usage, auto brightness: 200-240mA
Screen 100% red: 244 mA
Screen 100% green: 302 mA
Screen brightness off / CPU 100% load: 305 mA
Screen 100% blue: 354 mA
Screen 100% white: 476 mA
My phone lasts about 3 days depending on usage (65-75 hrs).
My Display usage (according to menu) usually is on the range of 2-5%
Normal battery drain in the range of 175-250mA at average brightness and usage.
Making it darker than I already have, maybe I could squeeze out 25mA (50mA feels impossible).
I would guesstimate I could gain another 30-60min, if I'm very lucky.

Task killed in Froyo?????
Seemed to me that Android team succeded in avoiding people to use task killers in Froyo...
Is that still possible to make the mistake to use a tsk killer?
By the way, how did you get your battery usage in your phone? are they general stats or did you getthat by an application?
I googled "sysfs" but cannot understand what this is.

Ohh. Sorry.
Unneccessary tasks/apps killed.

Good call! I Google in black on my phone at bGoog.com to make my battery last longer too...

Battery apps and widgets

I have tried a few and they all seem to suck battery more than the opperating system if you want them to run in the background and record and type of advanced statistics. I would like to get every day Joe's opinions and recomendations on battery apps that work well and record good statistics like
* % a hour of drain
* good battery graph
* apps and processes and there ram and usage % of cpu they consume including the app its self!
Lets get this one figured out together for the best apps that really work! Thanks guys!

The app I found best for general use is SYSTEM PANEL

[Q] widget locker and battery drain

i've been browsing the "post your home screen" thread in the themes/apps subcategory and i've noticed that a lot of people use widgetlocker to get really impressive looking lock screens.
im debating getting that application too but reading the reviews of the application, it seems some people are having battery draining problems. can anyone who is using widgetlocker comment on their battery life and whether or not using widgetlocker will cause any noticeable changes?
i primarily just want to change the lock screen wallpaper and add a few toggles

I use Widget Locker and have not noticed any excessive battery drain. I've used it for some time both on the Droid Incredible and now on the Galaxy Nexus and have been quite pleased over all.

No excessive battery drain here.

I've been using it since it was initially available and have used both stock and WL for various periods.
Unless a bad widget is used in WL it causes no appreciable difference in battery usage in my experience.

[Q] Widets = Diminished Battery Life?

As the title suggests, I was wondering if the use of widgets on the homescreen greatly reduces your battery life? I'm sure it's a very naive question, but my real concern is if that drain is INCONSEQUENTIAL? Is it really worth it to make a more streamlined homescreen, bereft of any ease-of-access apps?
Thanks!

It's not the Widget as much as how much data does the widget use, especially if you aren't using WiFi. (3G/4G data is a battery killer) For instance if you have a weather widget or a facebook or twitter widget that updates every 15 minutes, that's going to be a major battery killer. If they only update when you turn on the screen then the battery usage is much lower.

^^^^ this... it all depends on the widget... if it's a data using widget, yes, it can eat through your battery faster than a seafood lover eating lobster, if it's a music widget for a music player, not so much

shut off all widgets = battery saver
turn on all widgets = battery drainer
