[DISCUSSION] Battery life with overclocking is epic!

Only had the phone for two days so this should improve even more:
overclocking to 1.4ghz, under clocking when screen off to 0.3. 9 hours screen off, didn't lose a percent, still 100 on desire Z. EPIC!

thats good to hear ! Cant wait till i get my hands on it! damnit ! 5 or more days togo

Did you have any other functions enabled? 3G/WiFi? Sync'ing with FB or Twitter apps? Anything like that?

how many hours can you get out of it when you are using it throughout the day, e.g. email, internet browsing, twitter, bit of music and phone calls? using data and wifi?. Im on my 5th day and averaging about 14 hours, hoping that the battery hasnt settled yet, otherwise my hope is for the NAND being hacked and roms for optimal performance!

Do you actually get more real-life performance out of the overclocking (snappier menus, faster app launching), or the only place where it shows is the benchmark? Is Sense faster, or is the difference not visible (0.8 vs 1.4)?
On the other hand, underclocking could be really useful to preserve battery. But doesn't the processor underclock on its own when in standby (by design), do we need to use 3rd party apps?

contrary to what you should expect,
overclocking this SoC just hightens the clock's max roof from 800MHz to 1GHz, 1.2 or 1.4GHz, not the "permamnt" MHz count,
because it auto-fluctuates and adapt depending on usage
AND with the SetCPU app (which I assume JupiterDroid is using),
cycles per second can be optimized even more.
The phone won't go up all over the way to 1.4GHz when idle, but will maintain a very low cycles per second clocks, thus improving battery life

Here's my experience w/ battery life and overclocking the Desire Z (for today).
I only have it set to overclock to 1GHz and I have typical SetCPU profiles to underclock to 245MHz when not in use.
My phone has been off the charger since 9am (5.5 hours) and is sitting at 92% battery power. This includes permanent connection to WiFi (no sleep policy), receiving updates to email/gmail and some text conversations with Trillian and a 15 minute email (composed w/ keyboard).
Compared to my old HTC Hero (Running VR 1.5.0), this is a huge improvement, though with VR 1.5.0 I could run JuiceDefender & have similar battery life with the right profile setup.

Yup I even notice better battery life in actual use. My friends were running youtube and doing web searches like crazy on my phone last night + games for a good 5 straight hours and the battery was holding up well.

I've got to say, the battery life on the Desire Z is outstanding... 18 hours with light use and battery still @ 92%!!!

What about 1GHz core compile?

are you using set CPU and overclock?

Is anybody getting time without a signal percentage in the cell standby item in the battery usage? Im getting 12% sometimes more and im getting about 14 hours battery life with moderate use! I dont feel im getting the best out of the battery and worried this might be part of the issue!

Hi guys.. sorry for the novice post.. i have had my Desire Z for a day and am interested in overclocking it - but
a) are you saying it possibly INCREASES battery life?
b) is the speed diff noticeable in day to day use - or just benchmarks?
c) How do i overclock - what is SetCPU and how does it work?

I don't think my battery has settled yet .. I hope not anyway, and I just (temp) rooted and overclocked to 1Ghz last night, haven't tried higher yet because I feel like my battery is kind of just disappearing so far, none of this epic "all day and then some" stuff some people are reporting. I think it may be that fact that I've been using the device pretty sporadically so far, and it hasn't had a chance to settle.
Also "cell standby" seems to be using a lot of battery, and I'm thinking that's because I'm unfortunately in a spot where I get extremely poor to no coverage most of the day. So I'm thinking the cell radio is using a lot of juice trying to get that 1 bar I sometimes see here. There didn't seem to be a way to easily disable the cell radio without disabling wifi though, until I found this "airplane mode wifi tool" on the market which I just installed.
So now my cell radio GPS and bluetooth are all off while wifi is on, hopefully that will make a difference. I'm wondering if using 802.11n is more draining than 802.11g also I know both my router and the desire z support N but "network info II" reports I'm only connecting at 65Mbps, while my laptop connects at 150Mbps.

I don't think there's any way overclocking can actually increase battery life, but managing CPU speed with SetCPU seems to be more effective than the default behaviour for some reason, so the fact you're overclocking when using it but underclocking when not using it results in longer battery life. I'm pretty sure it does regulate the speed automatically without setCPU but maybe it doesn't clock the CPU down to absolute minimum by default when the screen is off?
Anyway the noob friendly guide to overclocking by JD is on the forum with an [INSTRUCTIONS] tag.. I can't link to it apparently since I'm a noob.
Edit: Added link ~TheRomMistress

Thanks guys. Main thing i'm curious about is whether i just install SetCPU or i have to "root"

Yes, SetCPU needs root access.

Still trying to figure out how the OP is underclocking to .3 using SetCPU.. Lowest I can go is 245..
Unless I'm an idiot and completely missing something.. I'd love to turn this phone way down when the screen right off. As it sits, I'm lucky to get a full day from a fully charged battery.

Your mileage may vary
You can check by yourself and then uninstall if you are not satisfied (or just reboot and changes will dissappear, since we don't have permanent root yet)

setcpu for htc desire hd - 1.5 gh HELP

Hi can someone giv me a setting for desire hd i want it to be fast like a buggati and a good battery life settings.

If you have Buzz OC/UV 1.51Ghz installed, which I think your referring too.
Screen On - 368-1401 - performance
Screen Off - 368-368 - conservative
I use those setting and have no problems with lag, or battery life. I listen to a lot of music with the screen off and I get a full days battery.

waw these are crazy settings and you get good battery with these?? i will try it

If you use your DHD with the screen on more then perhaps adjust the clock speed.
I listen to the radio till 0930 then use doubletwist till around 1500. All with the screen off. I have around 40% remaining. Which is more than enough to last the rest of the day. Install juice defender too. Probably the best app you'd ever use.

i'm currently using interactive at 245-1113 yes yes i'm very conservative, but i'm satisfied with the speed, its so smooth when i unlock the screen by the way i'm on buzz v1.0.6 (later versions, things started going crazy for sense)
i can imagine with your settings it will fly, since 245 usually lags
were is juice defender? can't find it on app brain
ps. the radio is one of the best things in HTC phones

Juice defender can be found in the regular market.
I found I had "wake up" issues if the clock speed was below ~300mhz.
I like my DHD to be very quick & responsive when I'm using it. And practically hibernate when I'm not.

Hi everybody,
as new user I cant post on the right post. So I ask you directly
I would like to test the new 2.3 with the Wolf's TW GB (http://forum.xda-developers.com/showthread.php?t=1192988) but I saw some people who had problems with battery autonomy.
I run, right now, the 2.1.A.0.435 and I'm really satisfied about the battery. My X10 is on for 40 hours and I got 74% battery. Yes, I don't use it very much but it's enough for me.
So I wanna know how the battery usage is with the Wolf's rom and if I can test it without being disappointed.
P.S.: sorry for my ugly english

I cant speak for all users but my battery drains very fast. I dont know why, but might its because I often use wifi and my screen brightness is set to maximum.

Doooooooh, using wifi and screen brightness to the fullest drain battery. on my side i can tell you that wolf's rom with the hotfix is perfect. I can go through the day easy with screen brightness to half, no wifi, im on 3g all time, listening 2 hours a day some music while playing Asphalt 5 on my way to work. So yes battery is ok as long as you don't use to much wifi and bluetooth.

from what ive learned in the year or so ive been using android phones is that everyones battery experience is different. I find 3g drains my battery and wifi doesnt. All you can do is try it for yourself.

Wolf's TW battery is suburb for me ;-) i moderately use my wifi, Bluetooth, brightness, etc.
After 17hrs of slightly heavy using its 61%

May I ask a question, with all due respect to everybody's work?
Why would you use a modified stock ROM,
be it WB's or anyone elses, since we have root, which means that you can tweak the stock ROM to your needs?
I mean, it's one thing to have CM ROMs or MiUI ROMs or vanilla Android,
but a modified stock ROM is still stock people!
I much prefer to make tweaks on my own, remove what I don't need, etc.
Just my 2 cents.
Again, I mean no disrespect, WB has been doing an elaborate job on his ROMs.

my battery lasts twice with 2.33, (i was before on WB froyo), with normal use 16 hours 50% at the end of my long day.
so battery life is awesome, i think is becouse is not as smooth in some games and apps.

not everyone can invest the time to learn the tweaks, and WB is based on CM isnt it? anyways i am loving the battery on my stock GB, will probably root it to get titanium to work and remove some of the bloatware, Ive used WB 2.2 but the battery really sucked, tried alot of BBs but didnt manage to fix the drain

You should really try-out this ROM. It has speed tweaks/battery tweaks ported from another devices. This is the only ROM for the x10 with these tweaks.

I am using WB's rom with FIX005. The battery not drain very fast.
At least I can use it for whole day.

Yeah, but learning how to mod your phone is half the fun!!
Anyway, it's good that there are options and I know WB makes really
fast ROMs, his 2.2 was very snappy and stable.
However, what I've been trying to point out is that WB's 2.3.3
is not CM, it's stock SE ROM, tweaked.

I can tell you that there are there alot of apps in the background running that are not being killed. Much more then on Froyo/Eclair. So what stops you from trying it out?!
The most important ones I got running are:
- WhatsApp
- MSN Talk Pro
- Google Talk
- Facebook
- Seesmic
- LiveProfile
- KikMessenger
- Skype
- Viber
- Data Monitor
- DSP Manager
- Equalizer
- SwiftKey
- Widgetsoid
- Beautifull Widgets
And much more...
And none of them have ever been killed, they all worked fine! Battery life is also great! They are always running in the background. (If in your case the apps are being killed to fast, there is a way to tune it down to what you want!!)

on 2.2 tw 009 the phone keep working for almost 4 days of normal usage, now on 2.3 tw 005 it acts weird, sometimes it looses 20% in 1hour, but average it keeps for 2 days

Hey in hotfix5 there is GoogleTalk1.3 which support videochat. Does this work on the x10?
Edit: Doesnt work, I always get a fc when i klick on the camera-symbol

I will test that, right now
Thanks all

3 hours unplugged, and little to no use, and my phone is down 40%
So my phone is using way more power than it had under 2.1 I'm going to guess that it has to do with the baseband, and localization for me.

I switched from Wolf's 2.2 / 009 to 2.3 / 005 on my business phone. 3 hrs music per day (that's the time I need from home to office) many phone calls, gaming, testing, playing. I've to charge once a day. Think that is not to bad.

What sort of battery drain do you currently get on standby? Can you tell me the reading in ma from CurrentWidget? If it's 3-5 ma with mobile network/wifi/bluetooth etc on and 2ma in airplane mode then you're fine,but if it's higher it can definitely be improved.

If you don't plan to use mobile internet connection then disable 3G and turn 2G mode only. Turn off as many widgets as you only can, disable Location Service and auto sync. Install apps on phone memory only.
Also Dorimanx kernel is a hell of battery drainer, use another one like stable Tytungs etc.
Use dynamic/powersave CPU governors or use CPU speed profile apps like SetCPU and make several profiles for it.
This is only a few of tips we can give here.

Well the apps I use to reduce my battery drain are JuiceDefender and SetCPU. Set the profiles to be 245-576 Mhz when screen is off (smartassv2) and whatever else you like when screen is on. I never had any overheating problem with Tytung's kernel though. It was the most stable and just as fast as Dorimanx's kernel IMO. Still, using ICS now so I can't really judge about the newest versions of each of them.

I think his kernel is the same in battery drain over any of them. Ive tried them all. If anything, seader_r9 was the best and it was only a small improvement. My battery life is pretty short, but im a HEAVY user. Constant web browsing, constant text messaging contant GPS. And it lasts for the majority of the day. Now i have an .sh script which helps tweak the smartassV2 settings. I get about 110-200ma drain when doing simple web browsing or replying to a text.
One must also keep in mind that the ROM has a major part in battery drain as well. I heard from many users on here that MIUI has the best battery life. All in all i think any kernel you choose will have reletively (i spelled that wrong -.- its still early ) the same battery drain. It really comes down to the amount of use your phone has. But as stated before, turning off data greatly saves the battery as does turning down the screen brightness, fyi, automatic brightness sucks battery life too. Plus android does a horrible job polling the light sensor -.- it shouldnt take an average of 3 seconds to get the changed light value..
Theres not much 'tweaking' you can do to give you like an hour extra of battery life. Our batteries are only 1350mah batteries and thats really small for such a huge screen. My Touch Pro 2 has a 1500 and a much smaller screen. There are a lot of good aftermarket batteries on ebay that you could get which would extend your running time.

thanks guys, im gonna give a shot to tytung kernel, but im also gonna take a look to the aftermarket baterys

Typhoon rom support undervolt so if your phone is gettin' hot I suggest you to tweak the voltages as explained to original thread first page, it makes a big difference compared to stock.

Good advice here. There's a lot you can do (as already advised) but always some performance tradeoffs. The standard HD2 battery is only 1230 mA... not 1350. Smartassv2 in DM's kernels is excellent for performance and settles down nicely in standby - but it will pull-on your battery when used. There's no substitute for keeping a few extra charged batteries around (when you need them), along with AC & DC chargers + cable, in a small carrying case.

You don't need to use dorimanx's latest kernels, his stable kernels in fact do a better job at not overheating and have only 2ma drain on standby. I know 5.9, 6.3, 6.4d, and 6.9A (ics hwa) give a great battery life.

Which apps are running in the background? People constantly say that task killers make no difference yet whenever I've opened something and haven't killed it I get a higher battery drain than normal.
Also, use JuiceDefender and SetCPU to lower the drain.

[ICS] We need your help... Battery life...

Since the beginning of Android one thing has always been an issue with some of the greatest ROMs.
........................Battery life.
Every day lives are drained away by the pleasures and features of such fantastic ROMs... and such things at time seem so hard to bare that we try to change the lives of our battery by going to a different ROM.
So now you have a chance to make a difference, nay, an opportunity to change the lives of many...
This thread is strictly for how to save Battery life. CM9/AOKP have amazing battery life by themselves (but yet can always be made better) But for those on MIUI (Not so great battery life) this will be really useful.
Understand that everyone's device is different and although you may get 15 hours off MIUI/AOKP/CM9 others may only get 4 from them.
Post what it is that helps you achieve maximum Battery life. You may be the one to solve the cure to wowhowdidmybatterylifedroptwentypercentinanhourosis.
Be sure to include:
1. ROM
2. Kernel
3. Tweaks that have been applied through ClockworkMod
4. Apps used to save life
5. What battery you use
6. How long your life lasts
7. Anything else that you think may help

Uhhh,,,on ANY ROM...but not a practical solution.
I think the OP is looking for more practical solutions where they are not disabling major features of the smartphone.

1. CM9, although i think aokp does better.
2. Samurai Kernel, although just about any other ICS kernel should help. The biggest thing that you can change between kernels is the Governor and I/O depending on these two will determine how the CPU runs and in effect will determine battery life. Conservative is just about the best for battery life. If you need slickness and not too worried about battery Ondemand. If you want the best of both worlds i Think Wheatly is a good compromise. Also I/O , Sio is "simple" but VR is flash based so it tends to be the best. Otherwise Noop/Deadline. Also voltage.. undervolting will help limit the amount of well voltage to the CPU. So the lower you can get it the better.
3. Dont have tweaks i apply through CWM but i Run the V6 Supercharger, 3G turbocharger(optional), and the Kick Ass Kernelizer from Zeppelin.
4. I cannot stress this enough, Apps that say they save battery... run... which uses RAM and Resources... meaning its running trying to save you battery, Using battery. Which is stupid... and useless.
5. I have two a 3500Mah and the stock 1.5 year old 1500mah.
6. Typically with 3 hours of display over a period of 15hours (1500 mah) and around 5 hours of display over a period of 22 hours (3500 mah). However this is on wifi, 3g would deduct these a pretty good amount if you have sucky speeds.

He needs to get over it... lol. The only thing that truly saves battery life is managing your connections. There is no magic bullet unfortunately.

PLEASE! Don't tell us to turn off data and never sync the phone. Obviously if you don't use the phone the battery will last forever. I need a phone that can do the following:
Receive emails and texts as they are sent. (I use exchange push)
Last 18 hours on a standard or 1800 mAh battery.
I can just barely make that with stock FC09, I'd love to run ICS but with either CM9 or AOKP I barely make 10 hours.

Why must people post unhelpful comments such as the one above? I don't understand the logic there...
anyways since this was aimed at miui I get pretty good battery life with it... (3.5 hours screen on time) nyan v5 ftw! No special features... uv a lot (won't list my settings cuz every phone is different) and no oc... used to use jd but, it saves more battery if you just switch things off manually... really though until I flashed nyan my battery life was atrocious, but now just about on par with the peoples rom (4.5 to 5 hours screen on time!) Oh yeah, all this with the stock battery...

On aokp with 1800 mAh i can do about 3Hours of screen on time and 15 Hours of battery life and my phone was awake 75% of the time.
Screenie was at 15%
This was stock Everything Except ROM haha

Think about if your screen was on while the device was awake..your time would be cut in half

Oh my good golly gosh.
I just realized the best battery life I ever got was on DK28.
So take that. Let's go Frankenstein.
1. CM9 KANG June 02 build.
2. Stock
3. Services for V6 and Search Key Remap
4. Ha!
5. Stock. Came with device...need new one.
6. Depends on use. But I usually get the estimated six hours consistently.
7. If you're going to use a task killer just use the built in one. Overclocking is bad, and in my experience so is undervolting. GTalk, official Facebook application(especially this. Even with notifications off it still is always going), G+, and more are always running and are a drain. No live wallpapers, and no widgets that require constant updating. As much black as possible. Don't use third-party batteries. Obviously turning off 3G, 4G, sync, and such will dramatically increase your battery life.
WAIT! Why am I writing this? There is a freaking optimization guide. Why does this exist? For ****s sake.

Running AOKP build 36, stock, FC09 modem 15 hours running takes me down to 50% batt hour of screen time, constant crappy wifi connection in an area with crappy cell signal sync for everything but email and g chat is every 2 hours (weather and all that). Big thing to save batt for me was turning down my screen brightness. I was also getting crappy battery life till i let this rom install run the battery down to 5% twice.

By no means was I saying never enable your 3g/4g.. but the fact remains that the single best way to conserve your battery life is to be smart about managing your connections. I.e. not leaving it on ALL day and to only turn sync on when your actually checking your e-mail.. be that through an app like juice defender or manually toggling. If that's not more helpful than what you posted (UV a lot and don't overclock??? Duh.) than my bad bro!

Something we can all get behind here... I remember I used to get 24+ hours on froyo w/o customs kernels. Le sigh..

-I don't use the supercharger, but I do apply the same oom ram mods. These help close unused apps when they exceed the applied limit. Based on my experience, it's kept apps under control.

-THIS +9000! An app that spends all of it's time stopping other apps is wasting just as much "battery." I maintain, Advanced Task Killer, with NO, I repeat NO AUTOKILL. Set a widget on your home page, tap it occasionally to make sure everything is closed. Same effect as the built in task manager, but one single convenient tap.

-These numbers are pretty much the same for me. I almost always average 3 hours display on the stock battery between games and internet. 5-6 hours on the 3500, but I'm pretty sure it's not reaaallly the 3500mah it claims to be... . I NEVER turn off wifi or 3G, but google autosync is off until I edit my contacts.

I don't turn off my connections at all and get great battery life... and seens how the op states don't say anything about disabling 3g or anything id say your comment was the least helpful on the thread... but at least you tried... don't get into a battle of witts with me, I'm afraid your unarmed...

Firstly, I'm not trying to get into a pissing match with you. Its pointless. Secondly, the op makes no mention whatsoever of connection status. Thirdly, while you might get decent battery life w/o doing it.. I guarantee you'd do better if you did. Straight facts.
Edit: I am armed. With a small slide out keyboard.

Please follow the format specified by the OP. List the 7 items. Bickering in this thread will not be tolerated.
Thank you for your cooperation

1. CM9
2.ShadowKernel (I find nyan colonel to be a little more draining) SIO, conservative
3. None
4.System Tuner Pro configured to UV, under clock to 400mhz on screen off, to close apps that don't automatically restart themselves, configure "auto-kill" so its not as aggressive with killing apps that just stay on, and a few sysctrl edits that I honestly don't think make a difference.
5.stock epic 1500 mAh, my sprint store wouldn't give me an sgsII battery
6. 12-18 hrs depending on use, though it has definitely drained quicker
7.be easy on data! (There kennyG) turn off wifi when your not near your networks, turn off mobile data, Bluetooth, and autosync when your not needing it. (Unless you absolutely need PUSH email for your job or whatever though honestly as far as my job goes if its important enough for me to need the message immediately they will simply dial my phone number. Yeah I'm old fashioned.

- Cm9
- Shadow kernel
- No tweaks
-1800 D710 battery
- I get 15-20 hours depending on how much music I stream during the day.
- I got the biggest boost by using the profiles in CM9 to optimize my connections and syncing depending on where I'm at during the day. I have Wifi at work and home, so I have it toggle my data off during that time period and vice versa when I'm mobile.

Using AOKP with shadow kernel.
Best thing I did to help with battery life was to turn off all notification options in the FB app. And I set haxsync to download photos only when plugged in.
