Better battery life!

Hey guys & gals just wanted 2 share something with u. I recently decided 2 uninstall cetcpu from my phone & decided 2 go with cpu tuner instead.In doing so i've noticed my battery life improve significantly with some profile tweaking of course.If you've run the virtuous htc sence rom with the pershoot o.c kernal u know how disgusting the battery life can b.It literally sucks the juice out of your battery like "Debbie" from Debbie does Dallas sucks the juice out of...well u know. Anyway,i also noticed how little juice the system resources now use up. I included a screenshot of the battery status screen.Hope this helps anyone with battery issues especially if your running the rom & kernal mentioned above, it worked 4 maybe it can work 4 u. P.S I have the screen set to 20% brightness,gps,wifi,blutooth,autosync all disabled.Only reason i mention this is because even with all these things disabled along with a few other,b4 installing cpu tuner my battery would still drain like crazy. Thx.

That's some horrible grammar.

Useless post, This isn't grade school or school period. If your worried about grammar over the Interwebz then i dont think you should be posting on a forum site.
Liek ma grammarz?
Anyway, Your saying the cpu tuner helps the battery life? I'll give this a go but I don't use any of the sense roms. I'm all for better battery life although I do get 15h on pershoots kernel running cm 6.1 stable.

i have almost the exact same info on mine with setcpu oc to 1ghz on CM6.1 and i get atleast a full day of use with frequent music and texts. alot better then any other android phone.

I don't know how you guys are having such bad battery life. Currently at the moment I am at 22h 11m 51s since unplugged with 57% left. This is all with CM6.1 RC4 w/ wifi + wifi calling on all the time when I am home, autosync on for everything, auto brightness, and some use of gps. I listen to music on my phone for atleast 3+ hours walking to and from class + texting, browsing, facebook, twitter, fantasy league during class and the occasional call, pretty good usage. with setcpu on oc to 1ghz with some profiles set up.

what if im not running sense?

If it works with sense I would think it'd work with most everything else.

Is the phone not quick enough at 1Ghz? I keep mines on stock speeds, have setcpu installed but don't use, and have CyanogensMod on it. I get the whole days worth plus more of battery. I can't even kill it when I want to recalibrate it.
A whole day for me is about 16-20 hours for me without charging. This is MADNESS!

Not that the phone is not fast enough. It's placebo effect where people "feel" that it needs to be faster when they overclock it at crazy speed. The G2 has already proved itself a speed monster, none of the android phones out there can top it right now. As for the battery life, I honestly don't notice any considerable improvement.

Hey Vulgrim what radio are you using?
I will try out CM 6.1 TONIGHT just to get the battery life.
I do find that the main culprit in dire lifecycles is 3G which unfortunately is what I use the most (nomadic lifestyle and all...)

So what settings exactly are you using on the cpu tuner? Just wanted to know so I can replicate it.

My settings.
@quierotacobell...Under "Current" i have governor set to:conservative,Max:1094Ghz,Min:768Mhz.
"Profiles":
Performancendemand-Max:1097Ghz,Min:768Mhz
Good:conservative-Max:1094Ghz,Min:768Mhz
Normal:conservative-Max:1094Ghz,Min:768Mhz
Power save:conservative-Max:1094Ghz,Min:768Mhz(services set to 2g)
Screen off:conservative-Max:768Mhz,Min:768Mhz
Extreme Power save:conservative-Max:768Mhz,Min:768Mhz(services set to 2g)
Keep in mind i have wifi,blutooth, & sync disabled all across the board.Also i'm simply stating what worked for me it's no guarantee it's going to work for you.

Hmm how can you get better battery life with CPU Tuner because the lowest you can go to minimum is 768?

Will try that out Utorrent, thanks.

Better battery life?

Is there anyway to increase the battery life on the aria? I love it, and I love sense, but within about twelve or so hours of moderate use in the day my battery is left with roughly 20%. With cyanogenmod, the same period of time and usage, I was left at 60% battery. I know the sense launcher and Widgets play a little part of that, but even with my hero, battery life wasn't that much of a difference between vanilla and sense roms.

I would suggest an App killer. I have yet to try cyanogen's ROM but am on Attn1's Liberated Rom. I have Bluetooth enabled all day and by the end of 12hrs it is at 25% or so. Not saying switch. I would try Advanced task killer. Have many friends using that on their EVO's and Nexuses and their battery is wayyyy better.

I've tried all the tricks. I always have advanced task killer no matter what rom I'm running. I change thee location settings, network settings, screen brightness etc. I love htc sense but I don't want the battery life that comes with it. I know what my tricks are,i just want to see what the community had come up with.

I have read somewhere on the google (official google page about android stuff), using task killers does NOT improve battery life because background apps stated as "suspended" when they are in background. I dont know if I get it right. I will post link if I can find.
P.S. Couldn't find it but it was something similar with this:
http://geekfor.me/faq/you-shouldnt-be-using-a-task-killer-with-android/
Of course, you must take control off applications really "running" in background and preventing the phone sleep state. Not just "killing" all applications.

Mmmmm. If there's one thing that could drag me over from the standard Liberated ROM over to the Froyo ROM, it would be longer battery life.*
Perhaps I'll give it a shot this weekend.

* I've resisted the urge to switch, only because I've heard wildly conflicting stories about how fast it runs on the Aria.

don't use task killer it will kill the app but the app will just start up again in the background cause the battery to run out. it says its in the background and that's true but its not running its idle and isn't affecting battery.

I have to say, at stock clock it got sluggish at times, overclocked to 800 though its running absolutely great!
Sent from my HTC Liberty using XDA App

You might want to try out an app called Autostarts. Just make sure you don't turn anything off you really are gonna need. Try this with advanced task killer and the apps wont load back up.

Check that you do not have an app constantly running in the background - on my stetup, I found that the XDA app was burning 3-5% CPU time spooling in the background doing nothing. (using OSMonitor)
For what its worth, I went back to the Sense ROM (FR008) from CM6.1 because of strange battery behavior - some days dropping to 30-40% after a full day, others it would be dead by 5pm. I dont consider my self a heavy user either. I do not see a significant difference in battery life between the two ROMs, if you throw out the aberrant days that CM would go nuts on me.

Custom ROM with the best battery life :)

I have played around with a few different roms for my SGS2 and was wondering which one has the best battery life in your experience?

That's an almost impossible question to answer as there are so many different factors involved which can affect battery life both on a custom rom and a stock one for example.
signal strength
push
gaming
screen brightness
Everyone will have a different experience and your best bet is to try different rom's and choose the one which suits you as a rom which is great for them may not be great for you.

If some rom creator would make make a black-red theme for his mod it would be probatly the best mod... Of course with all other goodies and tweaks.
Black-red theme because it would drain the lowest energy from the battary in the standart screen mode, but since we all use mostly different apps with different colors it will vary anyway.

To be fair, although it is purely anecdotal, people who have tried different ROMS while going through the sameness of their daily lives should be able to make a relatively valid comparison of battery life.

All the custom ROMs out at the moment are extremely close to stock, so I doubt there's much difference.

It appears the battery indicator is often way off. I let mine drain as much as it could til it would not boot at all, then charge it for 6 hours. Now it seems to last twice as long on stock (2 days with a lot of use)

I'm going to try this right now. I'll just let it stream some music over wifi at a high bitrate to drain it quickly. And using GPS, Blue-tooth. Playing music through PowerAmp at the same time.

That would be funny if a lot of the battery problems are actually because we keep thinking it is flat when it isn't - it is just being mis-reported. Kind of iphone batterygate in reverse.
I had a lock up on my device the other night but didn't realise until the following morning when I found the device unresponsive and stuck on my last screen. Although I had to pull the battery to regain control, the screen had stayed on all night because of the freeze and the battery meter graph was red for about 7 hours. The screen was still on and bright before I pulled the battery though.
Think I will also try ignoring the meter today.

DHD become faulty??

Hi,
Over the last few weeks I've noticed that my DHD battery is not lasting as long.
It has got seriously worse over the last 10 days. Phone gets switched on about 7.30am and by 4pm is nearly out of juice.
Not really doing anything with the phone - just sitting there on the mobile network with good cell signal. BT is off. Power saving is at maximum levels (no animations etc). It used to last until around 10pm and still have a good 6 or so battery segments left, but now it'll be dead by 6pm.
Nothing recently installed.
Any ideas on what may have changed?

Install currentwidget from the market and set it to log current usage. You will probably find your phone isn't going into deep sleep which is caused by a certain app.
Also see which app is using most battery. This could be an issue. On average 4-10ma on standby is seen.

I feel your pain buddy, my Dhd used to only last about that amount of time before I rooted, but then again I used to be at it all the time so not exactly the same set of circumstances. Must say I've been pretty happy about my battery life since flashing a new ROM but there's still no way i'm gonna get a full day from it

BTW - forgot to say that when checking whats been using the battery, it says display is the component that be using it the most.
I always hit the sleep / power button when finished with it so it doesn't drain the battery.

I've considered rooting it (It's an Orange UK supplied device btw) but I'm scared of breaking it.
I put a ROM on my previous phone so I do have some experiance of installing ROMs so I think it'll be ok if I did it.
Could I put the latest stock HTC DHD ROM out it without any issues and what benifits would I gain?

I've been very pleased with the virtuous unity ROM, it's got sense 3.0 and is super smooth, much faster than stock and better battery life. I couldn't see what benefit you would get from flashing stock room again though but i'm sure you could check it out on the forums if you're unsure.
I used http://forum.xda-developers.com/showthread.php?t=1259821
And had no problems rooting whatsoever, just be sensible and backup your data and stuff and you should be fine I'd say. Dead easy process too, it's much less hassle than going through all the different steps that you had to before, just make sure you read through the details and you'll be fine

Rom with best battery life?

I've used about 5 or 6 different roms for my HTC One and right now I'm using SentinelRom for android 4.2.2 and I seem to be getting almost double the battery life then from the other roms. Which I love. Anybody have any input on this? Here's a screenshot. I've got 15+hrs on this charge and I still have 27% left. And I've used my phone pretty heavily.

I didn't believed that sense based roms were superior than each other on battery or performance basis since htc one x days. But sentinel rom actually gave me a significant boost on battery life on all of my devices. (Nexus 7, HTC One, Nexus 4)
So I'm going to agree with you on this.

Ya. Not sure how exactly they tweak it to get better battery life but I'm happy... The cool thing too is the maker of the Rom takes suggestions from people and implaments them into the roms if he can.

I believe that it's not really dependent solely on the ROM but there are a lot of factors like usage, brightness and other things that either give you a good or a bad battery life. I have used the stock ROM, Android Revolution HD, and Trickdroid, and I got about the same battery life from both ARHD and Trickdroid (I didn't really keep the stock ROM except for a day or two so I wouldn't know). It's sort of hard to track the usage exactly in order to compare between two ROMs, because I for one use my phone differently every day, depending on how much browsing I do, how many phone calls I get or make, how many dropped signals, the brightness level depending on the lighting condition, and such. I must say, though, that I am extremely happy with the battery life I get from Trickdroid but I cannot say that it gives me a better battery life than ARHD, for instance, because that would merely an unimportant opinion that is not based on facts.

I tried to run a full day similar to that of those with trickdroid, ARHD and RGUI. And I just feel like the battery lasted a little longer on this Rom. I'm not sure if these developers can tweak software to change how long the battery last or not? But it does seem like there is a deference. I guess I should run it for a week or so on each Rom to get a true test. All I know is I love this phone and a longer lasting battery makes me happy as I can use the phone longer
On a side note. I am getting pretty slow speeds on speedtest with LTE. I'm getting 2 to 3 bars? Anyone know what that's about?? I'm only getting like 1.5mbps down and same up??
