Rom Modules - Tweaks to your rom. Works for both stock and modded roms.
If there's undervolt module for your rom, use it.
Custom CPU governor such as smartass, smartassV2
(!) For some CM7 Roms, smartass makes your phone very lag, try smartassV2 or ondemand.

CPU & Processor
Reduce processor speed (Underclock).
Choose [powersave/conservative/smartass] governors. (!) Quite laggy.
[APP] SetCPU for Root Users
-Set processor speed and governors.

Extras
Use less UI-replace apps like CallerID, WidgetLocker, GO Locker etc.

Background and Running Apps
Use task killer ONLY for apps/games u wont use for the next few hours.
Dont leave task killer in the notification bar, kill it together.
(!) If u kill every system apps, your phone have to re-run them all over again. Thus battery drains.
(!) Watch what you kill
[APP] Titanium Backup's Freezing function (PAID VERSION)
-Prevent the apps from running without uninstalling them.
-Frozen apps wont be shown in App Drawer and cannot be launched. (You can defrost if you want)

I think automatic brightness is the best. If you go out during the day you won't be able to see anything on 0 brightness.

It's probably more convenient to just buy a second battery.

Good guide for those desperate for more battery life though.

 

[Tone_Capone]

Green Power is a much simpler alternative to Juice Defender and seems to work a lot better too!

Also there is no need for a task killer if you are running GB. Complete waste of time.

 

[zhuhang]

Task killer is much easier than GB internal app control. Save time, not waste time.
But remember FC task killer together thats all.
---------------------------------------------------------------------------------
Automatic brightness is good but not battery saving. The screen sensors have to work all the time and keep adjusting brightness. :/
Yes, we cant see anything under the sun. Thats the con.

1 more tip, uninstall useless aps

 

[Stupidusername7]

I have a Samsung Galaxy S running the FASTY ROM, and when I switched over to this ROM, I noticed I went from 6-hour battery life to 2-3 days battery life!

 

[armoredkin]

Go to every Apps that has Notification Interval in their setting, it updates in background although not display in the Accounts & Sync

 

[spinrite]

Leave you phone off. Usually gets me unlimited power and run times.

Dont get what u mean. Any example?

Thats a basic knowledge and everyone should know this.

yes. CM7 uses more than CM6.

Updated 20.2.2012
- Use less certain apps.

Thanks for the tips.. most of them are pretty obvious though

That means you are good in saving battery.

There have been good tips mentioned but I would like to add that all those battery saver apps just do nothing. These kinds of apps are just ads while some of them like juice defender offer androidees a paid version (Ultimate, Pro etc) which is just another trick where it may be useful for lazy guys who can't turn wifi, bluetooth or other connections or apps off themselves!
I haven't actually tried any of ROMs which are told to be effective (like "undervolt") and on this position I must admit that manufacturers' ads for their mobile products are just lies as I have a SGS2 and whenever I start to play a HD game or connect via wifi it just starts to drain the battery times times more than the advertised battery life!
The only and reliable way of saving battery could be just using carefully: HD games for maximum 30-45 min and wifi connection for 2-3 hours. Playing movies or music could be run in a more span of time like 4-5 hours. Otherwise you will have no remaining for calling or necessary usages!

Yes, thats why i dont recommend saving apps. Just for lazy people.

Nice tips. But the battery depands on rom, some of them uses a lot of battery

It's true, but other things also affect battery life (many of which the OP mentioned).

However, I just wanna add one thing which I'm sure many of you already know. But the reason I am mentioning it is because I witnessed this work on two Samsung Phones belonging to my friend and his wife: Galaxy Pro & Galaxy Mini (name of the phones, not my friends ).

At first, and on stock rom(not rooted) their battery life was horrible; and by horrible I mean less than 6 hours of usage (<24 hours idle).
I googled it and read somewhere, that fully recharging the phone then draining it completely (until it switches off itself) every day for a few days, the battery life will improve noticeably.

I told them about it; they tried it; and after only 3 days they started to notice the difference. They told me that it really made a difference. Now their battery life is 6-7 hours usage. 48 hours idle.

I know those numbers sound unrealistic but somehow it worked.

I have read this before, and it seems to be a common thing for battery life.

I haven't tried it on my DesireHD because I'm always hopping between different ROMs..

I hope this would be helpful for someone...

... my two cents Cheers!

Nice tips, thanks

Ways to maximize your battery life.

Generally when it comes to battery life I try to use those two tricks which work very well with ICS Roms.

I use ondemandx governor 122-1612MHz with suspend_freq=122MHz.
In order to achieve lowest power consumption in standby. You can tune manually Vdd at 122MHz =suspend_freq to the lowest value.

I also change in /system/buid.prop the value of ro.ril.disable.power.collapse to 0 instead of one by default in order to allow deeper sleep of the air interface.

Over all the type of ROM you are using, the age and capacity of your battery in your device also play a roll in the average time you get out of your device

1612MHz, what rom is that??
