Underclocking the Motorola Q9h to Conserve Battery Life - Non-Touchscreen Windows Mobile Other

I have become very interested in maximizing the battery life of my q9h (at&t carrier). I have made some tweaks that make it quite responsive - more responsive than maybe it needs to be, so I am thining that could allow me to underclock it and extend my battery life. Thanks in advance for any advice - I have applied as many tweaks for battery life as I can find and I believe there must be more. (battery life on this q9h is quite satisfactory as is though - i am impressed with this phone and recommend it). Thanks again.

Wow,i'd want to know how to conserve the battery life of Q9H. thanks

[Battery] Recommend widgets/apps/roms/packs/anything what could improve O3D's battery
- I found some apps what helps, similar to task killers, but they seems to be abit 'better' in some way, not sure if task killers are actually good, but I will give it a shot for a day or two to see some improvement.
- What about these performance packs, are they really improving performance, if there is such pack out, is it possible to change it to battery saving pack which will lower your performance in exchange for battery life and how long will it last longer if will made such pack?
- Custom ROMs, can they actually increase battery life without killing performance or maybe boosting performance AND battery life? and is there any good ROM out yet for LG Optimus 3D?
- Is it possible to use LG Optimus 2X rom's for LG Optimus 3D?
* TESTING:
- Battery doctor, it's task killer + battery monitor + log/graph for charging etc etc, will try it out and will see how good will it improve battery.

Software can have a great impact on battery life and custom ROMs can help without losing and sometimes even gaining preformance.
There are NO custom ROMs out for O3D, the phone is just a few weeks old, ROMs takes time, O3D will probably take even more time than usually since the 3D is new to the platform and to the once creating alternatives.
However there are things happening on the ROM side but don't ask for a ETA etc since there is no way of telling and people do it on their free time.

Nice to hear that, about performance improvement regarding to losing it.
What about other similar phone ROMs, like Optimus 2X, possible to import that in O3D just to add this 3D space seperate or maybe just make Sense 3.0 with 3D space. I'v heard Optimus 2X is same as Optimus 3D, it's just some features are in 3D, but rest seems to be same as in 2X?
Can someone please post some example of real world use versus battery life, so the people can get a feel how much the battery lasts on average.
Thinking of getting myself a O3D but i am concerned about battery life.
Juice defender,exellent!!save 50% of battery

You won't get 24 hours out of the battery I charge mine in the morning so its full at 9 ish and by maybe 9pm it can be around 30% or less but that is best case scenario.
I think if you don't have a car or a way of charging this phone a spare battery is needed to guarantee a full day.
Would be interesting to find out if the 1900mah battery's I seen on ebay make any difference.
I'm trying juice defender right now...

No the 2X or any other phone doesn't have the same hardware, the chipset in O3D is completely new (to the smart-phone scene), some things might work but something that saves battery on the 2X might actually do the opposite to the O3D, but have no fear, in general all Android phones get better at battery handling and performance as new ROMs are released both Official and Custom, also Android itself is getting better and since this is a dual-core phone 2.4 that is said to optimize for dual-core will feel a big gain hopefully
Juice Defender and other battery logs and optimizers made it worse for me. I leave gps and wifi deactivated until i need it,screen brightness on auto. I keep mine loading over night. I leave home at 7am and am back at 6pm with 40-60% left on my battery.moderate use,some calls music email surfing. Im really happy so far!

Just need to be patient. Afterall it is a very new phone.
I am getting the 1800 battery myself. it'll give more juice to the phone. Also if no task killer is used, you will experience a much faster drain in battery. There are tons of apps opened by default. So a task killer with careful plan will gain quite a lot in power saving.
havn't seen alot improvement from battery doctor, but atm waiting on new battery to arrive, will see how long will it take on new battery and is it gona be better then stock one.
also now using juicedefender with aggresive profile, will se how will it boost my battery life

[Q] SetCPU and Battery Life

So I recently downloaded SetCPU for my HTC Vivid and I was playing around with it. I was wondering what you guys think about using it for battery savings? Any specific profiles you guys use that work great? I'm trying to prolong the battery life of my device. Flashing a new ROM has helped a lot, but I want to squeeze as much as I can out of it. Is SetCPU really worth using for battery savings or will the extra processing it does to change around the speed cause it to not help me that much?

amazing battery.. better possible?

I'm using current venomxl Rom with elemental kernel (all default other than max 1.5ghz and flu overclock off) and getting what I feel are amazing results on battery life. On phones of the past, aosp style roms pulled better battery life, but I saw here in the forums people were getting better battery life with sense roms? Is that true? I posted a screenshot below of my battery life, sorry couldn't figure out how to get jpg link from dropbox app.

Would be nice to hear what Rom/kernel combos others are using and what kind of battery life you are getting.
Put the picture in your public folder. Right click on the picture and click copy public link, or something to that effect then paste the link in your thread.
In any case, the only things you could do to get even better battery would be to undervolt your processor and maybe underclock as well. Some phones become unstable however and while I noticed the general ui and most apps run fine with a clock speed of about 1.2ghz, some, more CPU intensive apps do lag a bit. You can also disable radios when not in use. I actually use juice defender to do this for me automatically, which is pretty handy though not everyone likes the idea of having an app do that for you.
Last but not least, if your radio signal seems low most of the time, you can try flashing different radios to give you a better signal which will, in turn, increase your battery life.
Hope this helps, maybe others have had different experiences?
I use viper and bulletproof right now ad I wanted a stock kernel with swipetowake
And this holds up damn well in terms of battery life. Never used elemental for long though so not sure if it's better or worse.
*edit* I forgot to add, you can also turn off fastboot. Your phone will take longer to power on but saves some battery life.

Such reports are often just anecdotal and very subjective. Like you, I've also seen people claim better life on AOSP or certain ROMs on various devices, but never really experienced it in any consistent or meaningful way. Battery life often has more to do with the radio and reception in your specific care, than anything. Sure, various ROMs on various devices may have some subtle difference in battery life. But unless you are very methodical and scientific about comparing them, there are just too many variables involved, and you are often just left with subjective reports and placebo effects.
Can't open your pic. But if you are satisfied with the battery life (enough to call it "amazing"), I'd just go with the ROM that has the features you like the best, and leave well enough alone.

[Q] Xperia T - battery saving ROM ?

Hi All,
I am highly dissatisfied with my Xperia's battery life. This is my first smartphone and never ever I'd think endurance might be so hopeless.
JB 4.1.2 which is the most current update is confirmed by Sony to be more energy-sucking.
Can you share some hint to save the energy? (synchro: off, brightness: max low, data: off while asleep)
Maybe some ROM exists which underclocks the CPU making it less draining?
I am not a gamer so performance is not the most important factor to me. I would value much much more battery life.
There is uniQue ROM designed my xperia.cz team I think.. it's said be be 25% power effective, any experiences?
Regards,
Witek

Question Are you getting better battery life with GOS on or off/disabled?

So I know GOS has been throttling our devices and whatnot, but Samsung has stated it is to maintain the temperature of our device and preserve battery.
Now I personally have it disabled/uninstalled through ADB App Control, and have been getting 8hrs SOT. I disabled it because I play games frequently and like the performance boost. However, I wouldn't mind having it on for all other aspects. Has anyone experienced better battery life with having it ON?
I'm US Unlocked Snapdragon 512gb, did not receive the new GOS update yet, not sure if I would even update because the phone is perfect right now in terms of battery life and playing games at optimal level.
Rule #1 - If a OS load is fast, stable and fulfilling its mission... let it be.
I don't know if I have it enabled or not. How can you know?
I have disabled GOS on my A51 and no battery improvements. It's same as before.
when you enable the labs option in game booster settings then you unlease all the power in gaming(lgos-off)...You will not see any battery differemce in every day use, but better performance and worst battery life in Heavy gaming..
