Im currently on Pinky Desire 1.8, it seems good and stable and everything, but im not sure about the battery life. Feeling hesitant to change to a separate ROM because it probably wont be as stable, and besides, ive practically tried em all.
So im just wondering, is there some kind of inner deper tweak that ROM cookers alter to improve battery life? Or is SETCPU just a magic worker?
well, I dont know what could determin the battery life in a custom ROM, bt SetCPU is really good! just go to profiles, selet screen off, and go right down to 245mHz, really did the trick for me! 3 days of battery with heavy use (3g off when not using the phone)
Hi, the main things that eat the battery are the screen on/off time, it's brightness, wifi, bluetooth, gps, 3g and heavy apps like satnav. You should be alright with most of the roms even if some of them are less battery friendly

sorry, have to correct you on that, The screen does not eat up the battery! 8 - 15% is tiny compared to the massive 80% by Android System! thats why its called Organic Light Emiting Diode.. if you have a SLCD then its even less!!

I am familiar that a 15 quid nokia lasts for a week, we are talking pdas, they all have OS of some sort.
What about this setCPU, I haven't used it, I tought the phone was scaling the cpu by itself. What does it do differently?

The difference is that is forces the phone to use from X to Y CPU, not more. It sets a cap.
Anyway, I don't really believe in SetCPU. My logic says that if for an calculation it needs to run the CPU at 1GHz for 1 second, forcing it to not pass the 250MHz mark will make that calculation run for 4 seconds. So the battery will be spent again for 4 seconds (instead of finishing the job for 1 second and that's it, job done).
Still, that is my logic, not my knowledge

3 days with the fallowing; 3g off, wifi off, bt off, screen brightness medium (auto), auto killer (about 260mb of RAM free), use Advanced task killer widget everytime I'm about to lock the phone, and someimes auto killer, Live wallpaper on (white circles, a clock, but mine is set on "Midnigh" theme), All apps on SD, Turn off internet (hold power button, till a menu comes up, and press the option that is at the bottom, or use a widget, +-> Widgets-> System (?)-> 3g I think, (sorry havn't used the phone in a while ;/)
3 days, gaming, listening to music (headphones), and I'm also running NeoPhyTe 5.3 if that helps (not the battery saver, the normal version
hope this helps! good Luck!
Alright but then why did you got a desire, you use it at 250mhz, no internet, screen dark, if you say you have a spare handset for calls . Point being why would you get a powerful phone and keep it on standby

I use it at 245mhz in screen off profile so its on 1 ghz when using the phone and 245mhz when the screen is off. The screen is normally set on automatic when not watching a movie i last charged the phone on 31st and today it is at 14%.
Try calibrating the battery

I was using Pinky's rom too, I changed cause if its terrible battery life, it was eating 5-6% an hour with wifi off and in idle.... Now I'm using a custom baked r8 rom from Modaco kitchen, battery life is excellent!

and it is a smarphone but why do I need internet on while my smarphone is in my pocket?! or when listening to music or playing a game?! I don't need my weather widget to update it self every 5 minutes, because I can just look out the window and see, and also weather does not change that quickly that the app has to change it self (once a day is enough). I do go alot on facebook, internet and sometimes on the XDA app.. I never use my WIFI cos thats why I've got a 1GB data plan, for which I pay extra..
I do play alot, abduction, robo defence etc also, some more demanding games.. asphalt 5 I also sometimes go on utube, and the usual sites you'd go and to check up on the world
So, yeah, not really offline all the time mate
Im trying to find out what is draining the battery on my EVO EVEN WHEN THE PHONE IS WITH THE SCREEN OFF and SUPPOSED to be in STAND BY MODE (using the power button on the phone). I have SETCPU installed to LOWER the CPU to 245/384 when the screen is off.. HOWEVER THE BATTERY SEEMS TO DRAIN .
This afternoon I charged he batter till the green light came on. Made one phone call for 10 minutes and then later another one for 10 minutes.. I do have GPS and BLUETOOTH ALWAYS turned on since I use them all the time WHEN the phone is on for various APPS and my bluetooth earpiece and car adaptor... After those 2 calls the phone is down to almost 70% from 100%...
I have SYSTEM PANEL and also JUICEPOLTTER, SPARE PARTS and MINIFREEMANAGER installed and the programs are set according to what I have been reading on here...
SPARE PARTS tells me the phone has be MORE THAN ONE DAY with sleeping and the most used app is ANDROID SYSTEM. I look at SYSTEMPANEL and UNDER MONITOR HISTORY I can see that even when there is NO DEVICE USAGE, I still have around 15-30% CPU Usage (is this normal?). I also have it set to get email etc automatically.. some every 2 hours and some software every 4-6 hours.
What could be causing the battery drain? What is the best program to use to see the cause?
Im also not 100% sure SETCPU is using the screen off profile.. HOW an I tell this??? Any help would be appeciated...
Have you tried turning GPS off? If it's not actually being used, it won't drain the battery much or at all. However, if you're actually using it, it will.
If you're using navigation, that's a big battery killer, as it does constant GPS + a large amount of data transfer.
One thing you can try is to open Spare Parts, then go to Battery History and choose "Partial wake usage" in the top box. Things with partial wake locks are generally the biggest idle battery users.

I read in another forum that there was a bug in the Facebook application that was causing the application to refresh its information several times an hour instead of once in a while at specific times.It would use power and bandwith when the phone is even in sleep mode with screen off. They also mentioned that there was a fix already issued for this. I cannot find the link any more to source it for you where I read this.
My stock EVO runs for days with the radios turned off until I need them.
Sometimes, if it ain't broke ...
My evo has been draining fast without all that on and well it's annoying. The only compensation I have is owning 3 batteries.

From your list I can only see two things I would kill these programs and wait and see what happens.
WUNDEREADIO
FACEBOOK
Everything else must run. For me Slacker radio kept my EVO on all day long eventhough I was not using it. The new version seems to fix that issue. I am guessing your problem is WUNDEREADIO. I would reboot (resets your battery information) kill Wundereadio. Then go to Settings, About, Battery and monitor your Awake Time vs Up Time. Write down the numbers. Turn off your phone and wait 10 minutes. You should see a gap in time. If so then it is Wundereadio.
Good luck
I think slacker and wunderradio were in the list because I just used them.. wunderradio inst in the list today.. BUT SLACKER is but not in the partial wake.. its in background ...
I changed my backlight setting from auto to using a widget that has 8 brightness settings and it is on the 3rd setting.. I dont know what the AUTO backlight was setting the screen at...
I also adjusted the MINIFREEMANAGER according to some settings I found online..
also I have SPARE PARTS set to AGGRESSIVE... would that have anything to do with it??
Check systempanel first thing when you wake up, but go into monitor, then history, and switch plot to top apps. It will tell you exactly whats been using the battery/cpu when there's been no usage.
As you know, the bt sucks a lot of battery, if you really do use it often, with a bunch of apps, you may want to consider tasker, which can be set up to turn bt on only when your on a call, or using certain apps.

Will tasker turn on bluetooth when a call comes in? IE will it let the bluetooth earpiece ring so I can answer it from the bluetooth earpiece?? also can I set tasker so that when get in my car, it will KNOW I am in range of a bluetooth speakerphone and it will turn on BT and connect??
I leave BT on all the time for these reasons....
Looks like tasker wont do anything for me with Bluetooth. The earpieces take too long to connect when a call comes in or I make a call and some even auto answer when they connect which I don't want. I wonder how much battery drain Bluetooth and GPS use if left on but idle?
Sent from my EVO4G using Tapatalk.
Yeah, it would have depended on how long it took to pair. Still try checking the apps through systempanel after a few hours of non-use though. That should help.
And gps doesn't use much until its being used for something, but bt is a constant drain.

On my old tp2 Bluetooth didn't the battery much. I guess it does on the evo

OK so I have been running for the past day and 1/2 without blutooth turned on.. I only have 3G and GPS turned on. Still it seems the battery drains faster then it should. I look at SPARE PARTS and it doesnt show anything out of the ordinary on PARTIAL WAKEUP. I have SETCUP to 384/245 when screen off. I do use SYSTEMPANEL to look at what is running and it does show a LOT of stuff such as SLACKER, SOUND HOUND, JUICE PLOTTER, etc... what else can I do for battery life.. I left for work at 8:00 and when I got to work at 8:15, the battery was already at 90% without doing anything....
Aldo how much battery drain does BT take if I leave it on? its a pain to remember to turn it on when I get in the car and turn it off when I leave...
I am running AOKP M3 with franco kernel #15.2, turtle governor, 350/1000 w/ stock franco voltages. I also modded the auto brightness levels to ones of the MID mod. I use WiFi at home; I have set the power saver to switch to 2G after 1m of screen off time. However, I an unable to get more than 2-2.5h of screen on time no matter what I try. I plan to purchase the extended battery, but in the meanwhile what can I do to improve the battery life? I have the GSM phone.
Thanks in advance!
I've tried all sorts of stuff and 2 and a half hours is the most i've been able to get.
In order to do that I was using mostly wifi, auto brightness and I had undervolted as much as possible.
I've tried all different kernels and i've just accepted the fact that with this phone and the way I use it that's as good as it's going to get. To be honest i'm satisfied with that because in order for me to get 2+ hours of screen on time it has to be my day off, otherwise i'm too busy.
Also, i'm pulling 14-16 hours per charge with 2-2.5 hours of screen on time which in my opinion is great. I just want it to last all day and for me it does.
Try LeanKernel.
I get at least 4 hours battery life with:
Version: GSM GNex
ROM: AOKP Milestone 3 (power saver mode off)
Kernel: Lean Kernel
Battery: 2000 mAh
Frequency: 350/1200 Conservative
UV: Stock
3G/HSPA/LTE: 3G/HSPA and my network doesn't support 2G
What's off: BT, WiFi unless I'm home, Sync for Calender Contacts Browser and Photos.
Brightness: About 40-50%
Daily, I use: Netflix/Poweramp/Spotify/Reddit on my daily commute. Phone/Poweramp/Spotify/Reddit/Browser+ in between commute.
Even without the extended battery like you I would at least get 3.5 hours.
#1- people getting over 3 hours of screen time are on wifi the whole time, have 4g off, are minimalists with no syncing and no voice calls, or a combination of any of these.
#2 - based on your graph you have a lot of wake locks. Look at how often your phone is awake when your screen is off. That is KILLING your battery life. Disable or uninstall rogue apps, and turn off GPS and location services seems to help with this. Also reduce your amount of sync intervals if you can.
I have stock 4.0.2 unrooted GSM with extended battery.

Look at the betterbatterystats for wakelocks; looks like lookout kept half an hour, the rest are mostly sync.
Try to remove all widgets for a while. This can rule things out.
I'm running the exact same thing M3 with Franco 15.2 except I have the extended battery. This is with almost 0 idle time. Literally playing games, rrading forums, texting, etc.

I only have the calendar, clock and palmary weather widges (6 hour auto update). As far as I can tell Lookout and Sync are the *****es - literally. But that doesn't solve the idle drain, with the phone sleeping, it seems like 2-3% every hour or something like that.
That doesn't sound right. I have everything running as well. I don't use lookout any longer though. I'm sure if I just did the idle test I can get over a day of on battery time and still reach nearly 5 hours of on screen time. That's mostly Wifi which is suppose to drain more battery life, but I haven't seen the difference from being on 3G. This is a good set up.

I think you should try removing lookout. Take for example my awake times when screen is off. I sync Gmail, photos,remember the milk, and beautiful widgets.
Also major battery awake drain in beginning of my graph is due to streaming Google music when screen was off so perfectly normal.
Sent from my Galaxy Nexus using XDA App
Alright, I will remove Lookout. What alternative do you recommend, in case someone pick pockets my phone? Preferably free or cheap w/ Internet access. I'm thinking of Cerberus, as it'll be impossible for any wanna be thief to remove; I suppose the 3 EUR license is for device, right? Does it persist through ROM flashes (i.e. based on IMEI).
As for WiFi drain, on 3G it would be worse - it's longer range thus it needs more power and if the signal is bad (lucky I get top notch at home, not so at school), it's even worse.
When I get some more cash I'll order the extended battery and a dock off eBay, then I'll have a large main battery and the original one as a reserve.
EDIT: I've added the stats for this day. Better overall, the phone was used more intensively so getting a bit higher screen on time is good. I disabled Google Talk, I see it keeping the phone awake for a significant time, but I never use it. I also get rid of Palmary Weather and switched to the built in app, I'll see tomorrow how it goes.
The screenshots on the original post show sharp increase in battery drain when there is a) screen on and b) no mobile network signal.
In my opinion, these are two if the biggest culprits. The screen is obviously a power hog, especially with max brightness, and the lack of a network signal forces the phone to increase power to the radio in order to find a stable connection.

Well with the screen there's nothing you can do; A big screen will use a lot of power, a dense screen with use a lot of power, both is even worse. If this were an LCD instead of OLED the battery life with Holo would be horrible. Turning the brightness even lower than my tuned auto levels is not an option - the phone would be impossible to use due to the glossy nature of glass. As for the network, I can't do anything about that - the school building is built from reinforced concrete, that sucks up the signal pretty well and it's downtown, where the signal is already quite shoddy; at home I have a celullar tower 1km away so I get excellent reception, not so downtown.
But I'm not complaining about those. I mean the background activity, mostly the idle wake time. I'll see what I get tomorrow now that I killed Lookout and Talk, those seemed to be two major hogs.
Seems like you have a lot of awake time. Try disabling Maps, Google+ and remove all widgets and test it for a day. If it is better now, you have ruled out signal problems.
Is there any way to reduce the interval of Google sync events? (gtalk_async_conn) When I was at home on WiFi I got a sync maybe once every few hours (seen as wake). As soon as I left and turned WiFi off the sync was like every 10 minutes, which is weird, as in the AOKP ROM Control power save settings I set it to PREFER WiFi.
Why do I get a LOT more sync wakelocks on mobile data than on WiFi when the ROM is set to prefer WiFi syncs?
best pattery save I have found is turning off various radios
I use an app Profile that can turn on/off bluetooth and wifi based upon the time of day. So it turns on wifi at 7 PM M-F and turns it off at 6 AM when I leave for work. I get great battery life, and I think it is due to the radios I turn on and off.
LeanKernel stable... all the way!!... ive tried his OC 1.42/230 but you start feeling the drainage...

Believe it or not, activating wi-fi when I'm at home has actually increased my battery life substantially. No need to even turn it off; at the end of the day, it takes about 2% of your total battery life.
Care to post the "Power saving" app you are using, TC? The one that can activate 3G after the screen turns off? For so long I've been looking for such a powersaving app.
I recently installed CM7, Afterwards my battery life is very low, At night I had about 84%, but at the morning it became 22%, Its very annoying. What should I do?
Another Problem, My phone doesn't even play 360p videos fluently after flashing CM7. It plays the audio first, then stops, then plays video, then audio,
I also tried MX player, Still made no progress.
Please help
To answer your battery problem, make sure you quit apps with the back button and not home. Check what apps are running in the background. Turn off GPS, Wi-Fi, etc.

Yea, I did that, And is juice defender effective?
Turn off auto-sync (Eats up a lot of battery). Remove unwanted apps (the ones that run all the time. Not games)
And I have never found juice defender useful. I never use battery-saver apps.
I didn't like juice defender, i bought the paid version then decided it wasn't for me, the best free App for switching things off when you're not using your phone is llama imo, it's relatively simple to get it setup to turn off data, wifi, gps and even kill apps when your screen turns off and then turn everything back on again when you turn the screen back on.
Also there is no need to uninstall anything that runs in the background constantly (Google maps for example) and cannot be killed by any task killer, all you need is an App called autostarts which will break the flags any App needs to turn itself on thus ensuring you have complete control of what is running in the background. All you have to remember is to close an App properly after use otherwise it will keep running.

Battery life sounds good to me, considering its a 1300 mah battery. But reflash the rom and see if the vedio/sound problems go away, if not its a bug in the rom. Hope this helps
Under/Overclock
If you go to Settings > Cyanogenmod Settings > Performance > CPU Settings, you can over/underclock your processor, which can help not only with battery, but with performance! Basically, set a governor (Smartass is probably the best choice for most users) which controlls your CPU frequency, the limits of which you can set below. Personally, I use 245-748 MHz, but you should try increasing/decreasing the settings from their defaults one by one, then stress loading, to see where you can get them without stability loss. These settings have led to a battery life that's somewhere between a full day and almost half a week, depending on how much I use it. If I just leave it overnight, the battery percentage shows no battery loss, but keep in mind that's with Autosync disabled. Also, if you have no need for instant notifications, try using the Data On/Off in the Power Saver widget, turning it on or off as you require data.
Hope this helps!

I would certainly recommend llama.. i read scratch recommend this in some of the threads.. i started using the same and am quite satisfied.. kudos to scratch
Screen Brightness
For 99% of users, the display is the #1 consumer of battery, which makes sense because you have a giant 4.65 inch 720p display that needs lots of power to run. The lower you set your brightness, the more battery you save. For a person like me, 50% brightness is usually the highest I use. Colors look clear, the screen is plenty bright to read, and yet it's not too high. If you want to save battery however, turn down the brightness to around 30%. If you're really in a pinch and need to save some juice, you can even turn it down all the way to 0%, but I would recommend keeping it around the 30-35% mark for general usage. In my experience, standard auto brightness doesn't work too well for me. It's slow to respond and either cranks the brightness way up or way down inappropriately. However, some ROMs like CM10 allow you to modify the backlight settings, which works quite well.
Maps/Latitude
This tip is a little more straightforward. If you use Google Now, you are using Maps location services which drain battery. It's always looking for your location to give you the latest weather, let you know about the cool sushi restaurant down the street, and other neat stuff. However, it needs to know where you are, so it's constantly polling the network for location data. So, shut off Google Now completely, or if you're like me and love it, just shut off the parts of it that you don't need, like Places and Traffic. I saved the big one for last. Latitude. The silent battery killer. If you're like me and you never use Latitude ever, guess what, it's probably still using your battery, so you need to shut it off. Simply open your Maps app, hit menu, then settings, then location settings, then disable location reporting and location history. Your battery drain should decrease significantly. I check this often because it seems to reenable on its own sometimes. Yikes.
Radios
WiFi is pretty fast at your house. Way better than 1 Bar of 3G. But when you leave, you leave the WiFi on, thinking it's no big deal. However, WiFi is one of the biggest battery killers, along with the other radios. So remember, just shut stuff off when you aren't using it. No navigation today? GPS goes off. Not using your headset? No bluetooth. Haven't invested in those fancy NFC tags? Shut that off, too. A big one is LTE. If you live in a 3G only area, what good is it to keep LTE on? It's just draining your battery. Turning Data off can save you money and battery. If you aren't one of the lucky ones still on an unlimited data plan, shutting data off will stop apps from using data in the background, and it'll also save a bunch of battery. However, you won't know when fnartsy123 liked your Instagram photo.
Apps
There are some apps that constantly use system resources and keep your device awake, even when you aren't using it. A major offender is Facebook. While a big update is rumored, the apps frankly sucks right now. It's slow and it drains your battery. Stick to the mobile website, as honestly, it works better now. That's the main one, but there are plenty of other. To identify them, I recommend an awesome app like Better Battery Stats or Appsucker from Google Play. They'll tell you what app is stealing your juice, and you know to remove it.
Auto Sync
One of the main reasons to own a smartphone is to stay connected, and I don't want to change that. I would recommend you shut off syncing for services and apps that you don't use. Check your Google account settings. You don't need or want all of your selfies to end up on Google+? Shut off instant upload. If you use Chrome instead of the AOSP browser, shut off sync for that. Go through and make sure you only are syncing what you actually use. Also, check your apps. Do you need to know when you have a new tweet? If so, leave it on. If not, shut it off. Furthermore, if your battery is in the red, shut off autosync altogether to save some serious juice.
Good tips, especially turning off google now, its useless and even worse its a huge battery hog.

Use Tasker to set a schedule to set auto-sync on for 2 minutes at 30 minute intervals.

Just to let you know that you can keep the gps setting on. It only uses power if you are using the GPS. So yes if you have like google now checking for your location it will use power but if you don't have anything automatically using GPS then you can keep it on and it won't use battery.
Another one that I use, i if you are root, i change de voltatge settings to lower value or turn down the speed
