better battery life

I've been using CyanogenMOD 7 and love it (mostly). The one thing I don’t like about it is the short battery life. I'm kind of new to rooting phones so it took me a bit to get it rooted and get CM7 rolling. I was wondering if there are any mods out there like CM7 that have better battery life? Or if there's any thing I can add to CM7 to give it more batter life?
I've been using android since the first phone came out so I’m already knowledgeable in what to turn off to try and extend the battery life, but I have noticed a big decrees in batter since installing CM7.
Thanks for the help guys

You can under clock the processor when your phone is asleep. This creates better battery life.

your phone automatically underclocks your processor when it sleeps (for most CPU governors), you do not need to tell it to do so.
I'm not picking on you fyi, I'm just making sure we are giving people accurate information... there's only one thing worse than no information: incorrect/incomplete information.
op: which version of CM7 are you running? remember, the more minimal your setup (ie less homescreens, less widgets, manual syncing of gmail and whatever else, etc) the better your battery life will be. this is especially true of newer phones that are getting heftier cpu & gpus that, while intelligent with power consumption, are going to drain even larger capacity batteries relatively quick with moderate/heavy usage.
how long are we talking with battery life? how heavy a user are you? for reference, I get around 16 hours of battery life if I don't charge the phone at all from unplugging to battery dying with moderate to heavy usage (texting ~50 times a day, sometimes up to 100 emails depending on what's happening at work, couple hours of calls, couple hours of streaming music [pandora or audiogalaxy], couple of hours of games [peggle and plants v zombies mostly - both of which are resource hogs], etc).
I have just learned to get used to the fact that the phone is going to die if I use it a lot, so I've purchased three micro-usb cables and a car charger.. that way, unless I'm in an area where there is no charge-capable usb port nearby, I'm always able to get a little more juice if need be.

but i also mean setting the max sleep to 368mhz. by default its set at 800mhz. sometimes with apps running in the background, the processor may go to 800mhz without you knowing

check out 'powersave' and set your cpu max to 806mhz. should last you a nice long time like that. responsiveness suffers, of course.
'ondemand' and 806mhz is the best comprimise for me. still fine with HDvideo recording, streaming audio, Nav, etc
if you really want to make it last... clock down to 400mhz, turn off all the sync, set brightness and timeout to minimum, all the radios off (airplane mode), and the volume down, on vibrate.

But some govenors don't drop the sleep to the lowest profile. In fact almost all keep it above the lowest clock. Other kernels allow it and you can also use third party to set it lower. When the tweaKr script becomes universal it will be even better =)

It suffers in powersave because it stays at the lowest setting only. No reason to set to 806. Lol and that bottom comment is hella funny =), but if he does that his phone will just be...a waste of pocket space.
Your best bet is to do some research on kernels. If you are using cm7 to cm 7.0.3 id recommened pyros kernel. If you are on 7.1 or a nightly over 121 I believe id go with eugene's streamline5. It did wonders for mine Also there is a battery saving tips. Google G2 battery saving tips. Should be first link that comes up.
Cyanogenmod roms are known to be battery hungry. Nom nom nom.

Mugen 3600mah = better battery life...

Can you elaborate on what kind of battery life you are getting now? How many hours, and for what level of usage?
How long have you been on CM? It takes a couple charge cycles of the battery after flash any ROM, for the battery meter to be accurate. Clear battery stats (as mentioned) then charge to 100%, let drain to about 20%, repeat a couple times. Don't drain until the phone dies. Some people say to do this, and its not good advice. Over discharge of Li ion batteries can cause them to no longer take a charge. There are people on here, on the Vision and other phones, that let their battery drain to empty, then the phone would no longer boot, forcing them to replace the battery.

Battery Life Optimization Guide

Rule 1: If you haven't taken these steps, you haven't done a thing in the way of actually optimizing your battery life, and please do not complain that your battery is bad if you haven't at least done steps 1 and 2!
Step 1: Use BetterBatteryStats: http://forum.xda-developers.com/showthread.php?t=1179809
This will diagnose battery drain issues. If you have apps that are sucking battery in the background, this will show it. Google the ones that have high partial wakelock, and usually you will get a diagnosis. It is also sometimes very easy to figure out what is sucking battery just by looking at the application that is holding wakelocks or having many alarm wakeups.
Step 2: Sync settings, make sure that all of them are either at push or as high as you're personally willing to allow between sync checkups. Any sync settings that happen too often will trash battery life.
Step 3: Radio based drain is a very big part of battery life! As such, if you do not need constant sync, you can turn off mobile data on your own when you do not need it, or go to the Mobile Network settings and disable always on mobile data. This can greatly increase battery life, but at the expense of sync not working when mobile data is off.
Step 4: Display brightness can greatly affect the power drain of the battery! You can either manually control the brightness, download Lux autobrightness to make your own autobrightness settings, or flash a custom autobrightness setting in the ROM in order to achieve this. It also can have the side effect of making the display of the right brightness when in the sun and in the dark, so it is always at ideal brightness to preserve battery.
Step 5: Make sure that the battery is calibrated. This is not very complicated. Download currentwidget from the market, put it on a homescreen. Charge the device until currentwidget indicates 0 mA charge. Use the phone until the phone shuts off. You might want to then go to hboot and drain the battery until it shuts off again, and then do a full charge again. Only do this once every 2-3 months, because this is bad for the battery.
Step 6: Adblocking! One big cause of battery drain and unnecessary network usage is downloading ads. If rooted, use Adaway and Adblock to block ads from ever being downloaded, and use Adaway's adware feature to detect and remove apps with adware!
Step 7: A radical step is to use Core Control or something similar to either underclock, undervolt, or just shut off cores. Undervolting is always highly suggested, as it will help reduce heat and give the phone a longer lifetime, but underclocking and shutting off cores will reduce performance!
Step 8: Custom ROMs and kernel experimentation might yield just a bit more in the way of battery life, and also give much more customization and features.
After this, you have likely topped out all that can be reasonably done to extend battery life. If you find that your battery drain is still poor, perhaps you have a defective battery, or maybe even a defective device (Highly unlikely, but who knows...). It is also possible that you simply have a use case that is much more than the phone can accomplish, in which case you can either use a battery case, or an external battery to charge the phone on the go.

if too much undervolting the phone freezes/ reboot ....so the best value for undervolting is between 50 and 100mv ....in some cases undervolting increases battery life and makes the phone cooler but not much ...

Under volting is when you tell the battery to provide a little less power than usual.
Which is why the battery life usually increases, as less battery is being used than previously.
But as stated, too much can cause the battery to not provide ENOUGH power, therefor crashes and cannot boot properly etc.

Pretty much, I would say. Drastic increase of battery in games: phone won't get hot => battery will last longer without overheating and, what is much more important, it will stay healthier in long run.
Even on wall charger while playing, my HOX won't overheat with - 100mv UV.
This is the main feature I miss on JB Sense without custom kernels

The problem is, the phone cannot get the same amount of energy, it consume (in fact, it is the millisecond, where the phone is fully charged, than it discharges for some minutes, than it will be charged again for three minutes and so on periodically). So, what I mean, you will almost never see 0 ma on one X or other modern phones. You can only see that, if device can disable battery while it is fully charge and use wall charger like a main supply. And the last device with such behavior was Huawei s7 back to 2010
So, 3-5ma is pretty ok.

Worried about battery life

I am a heavy texter with medium to low wifi usage. Sometimes I play games on my cell (Everlands) & last night I did some chatting.Usually battery last about a day but sometimes it goes down like after 16hrs which is quite low for what I have heard about this phone. Any way to identify the problem is ?
Maybe that is because I did not really charged uninterrupted on the first day due to constant loadshedding here in my city (about 1.5 hr gap in charging). I've heard Better battery stats is a good way of locating draining problems but I couldn't really understand it well enough to use it to my advantage.
Also I have set my brightness to lowest most of the time so thats quite surprising. Also net usage is mostly web browsing, no google maps or auto sync feature enabled as far as I know. Any tips about locating the problem ? Could hard reset possibly solve this issue ? Anyway my phone is less than 1 month old (3 weeks old) so should I consider taking it to service centre & getting battery replaced. Please help.

The battery is calibrating within 3 weeks if the phone is new (5-10 charge cycles) so the problem might not be a real one.
Are you on stock rom, stock kernel?
IF not, do you have kernel with overclock capabilities (titanium kernel, kiss kernel)?

The calibration thing sounds interesting. Everything is on stock. The phone is unrooted though I once thought of rooting it & rebooted the phone in recovery. How much does the battery last for u ? Right now battery has gone from 100 to 86% in 12hrs with somewhat lighter usage. Is this normal ?

I'm having 48% after 10 hours with screen on at 61% but it is like this because i plugged in to my computer last night to put something on the sdcard.
In general your informations are alright, that is a fairly good battery life. Remember that you have a smartphone with gpu and cpu, and it is normal to eat battery even if when you don't play with it because it makes stuff in the background.
The great battery life i got at 3 days with 50% screen on, wifi, calls, sms at 10-15% but not on stock, using CM9/Paranoid Android and tweaked kernel for better battery life .
In conclusion, don't worry about it. Your battery is fine!

If you really want better battery life try flashing a custom kernel like KISS or Titanium and undervolt your CPU.
I managed to undervolt mine alot (-300mV while idle) and battery life increased to almost 3-4days, which is really impressive compared to 1.5days it lasted before.

Its usually 1-1.5 days for me,its always on eater wifi or mobile network.
And i text a lot.Gmail,Whatsapp etc.
Screen is mostly at 70-80%.
As far as i am considered thats good,a lot of phones these days cant even get to 24h.

It works perfectly stable with the following settings:
Clock VDD (mV)
'24576 700'
'61440 700'
'122880 700'
'184320 700'
'192000 700'
'245760 700'
'368640 700'
'768000 850'
'806400 850'
'1024000 950'
Took me about 2 days to find them.
Sadly you cant go any lower then 700mV, seems to be a kernel restriction.

In my last charge the battery ran for about 1 day 6hrs when it said low bat, which is fine for me. However few times it oddly discharged like in 18hrs. Maybe I played too much games & used a lot of wifi at that time.

"Battery calibration" is snake oil. Period.
Also, I have 2 stock One V's in the family, rooted but no custom ROMs. Both devices on occasion (once a day at least) appear to be in sleep mode but taking the phone into a completely dark room reveals the backlight is still on (albeit very dim).
This is the only thing I see that's keeping my stock ROM from outstanding battery life. Even as is it get good battery life, but I also double check periodically to make sure the screen really is off.

[Q] Phone Battery Decreasing Itself

I bought my wonder from a friend. Phone was not used too much. I installed cm10.1 touchwiz rom 8 and madridii 3.0 kernel. Phone is spending nearly same amount of battery at deep sleep and active usage.
My battery run out at;
First day -- 1 hour phone talk 4 hours screen usage at 10 hours waiting time,
Second day -- No phone talk 1 hour screen usage at 12 hours waiting time. How could be performance of the battery different like that?
I tried different kernels and. I wiped battery stats and made battery calibration (deleting "batterystats.bin" and fully charge it again) I dont think that there is any problem with my battery. But i didnt understand where the problem is. Can anyone help me?

Maybe I misunderstood you, but it's normal the battery decrease even if you aren't using the phone.
Also, you can check if battery is bloated.

My problem is about weird battery performance. On active usage and deep sleep mode is spending nearly same amount of battery. When i look battery statistics, slope of the battery usage is not changing whether i use phone actively or not. I am giving same example again; first day i spent all of my battery with 4 hours active screen usage and 1 hour phone talk at 10 hours, second day my batttery was over with 1 hour active screen usage and and no phone talk at 12 hours. At battery statistics, screen usage and phone talk was first and second at that two day. Second day nearly all of my battery was spent by deep sleep mode. At that two days, i fully (%100) charged my device with same (original) battery charger.
I should say that i am not a novice My bluetooth, wifi, and gps was always off only mobile data on, and only 2G And at performance section it am using smartass2 (freq min 0.2 - max 1) and sio. At developer section max 4 process at background. I am using ipromeh's [4.2.2]Touchwi5 ROM build 8 with madridii's last 3.0 kernel. I made battey calibration and tried hursky's 3.0 kernel too.
I had a wonder 1 year ago but i sold it. I faced up with the bloated battery problem last year with my old device. I know it. Now, my battery is not bloated. New phone that i have bought from a friend was nearly not used. Therefore i can say that i am using a firsthand device without service guarantee. I have heards some battery problems that are resulting from hardware (something releated by battery on mainboard). Is the problem can be caused by hardware? If the problem is about hardware that will be quite big issue for me.
What can i do for solving the problem?

No, unfortunately my lcd panel is rev 2. I tried arco's cm 10.1 ALPHA (Build 8) rom and madridii's old 3.0 kernel. I have noticed that when i restart my phone, its cpu speed is holding at maximum value, even in deep sleep mode. I think my problem is arising from that reason. When i changed maximum cpu speed limit(at 1017), cpu started to work normally (down to the 245 at deep sleep). I tried that solution after 3 restart, it worked. Is there any permanent solution for that? Should i check my cpu speed after every restart?

The stucking at maximum frequency issue is known to me. It´s happening after you change the default governor to another one. I fixed this im my kernel.
About the rest is sounds to me like it´s the new Playstore and Play Services draining your battery. Maybe take a look at my little HowTo in this section on how to get rid of this. Install wakelock detector and check the versions of Playstore, Play Services, Maps and Youtube you have installed on your phone.

thanks for the reply, i will try your Playstore and Play Service. But i couldnt see your cm.10.1 kernel.

This is because I didn´t release a CM10.1 kernel. Only for CM10 and CM9. Might release one, but currently am a bit busy with other things. However, even if you have this happen with the kernel you are using best to avoid this is not to change the governor but keep it at default or not to use IncrediControl to do so as it seems this is somehow related to this app.

G Pro Kitkat Battery hogs

is it just me or is the kitkat ROM really sucks----battery pretty well?
I also notice that the CPU usage does not drop to 20 percent idle but when I used other ROM (JB based) it becomes 5 percent.
RAM usage is good but I think it hogs the CPU. I used cpuz on measuring the cpu usage

Where can I get the JB rom for OGP?
For me, Android was best at JB and went backwards with KK.
Yes, I've noticed absolutely horrible battery life with KK. KK just feels like it is several different parts all just thrown together.

The only reason I think is that theoretically JB uses more battery is that the system uses more voltage than the kitkat. however, what's less voltage use if the CPU is always busy and wakeups are just everywhere.

Hi guys, maybe you could post in some battery stats so we could know more about whats draining your battery in particular and suggest some fixes. I've actually experienced the opposite with kitkat-battery life for me improved. There was even an instance that I got the phone to last 30 hours, with 5 hours, 48 mins. screen. On another instance I got 15 hours life and 5 hours 25 mins screen on. I just lost the screenshots as I had to reflash stock when i was doing some G3 mods., but nevertheless i could post some new ones.
I value batter life was well and i'm curious to see how yours could be improved too..

What a battery life. 15 hours screen time?
how can we accurately measure? because I only use CPU-Z and installed DS battery saver to save power. right now it only used 2% of my battery during the night. (from 1:45 - 5:50am)
I see. can you tell me what app should I use to determine CPU usage of each app/service?

No, my battery lasted 15 hours, and my screen-on time (total time i spent using the phone) was 5+ hours coz i basically used my phone then for gaming the whole day I suggest you download gsam battery monitor app (it also has a temperature_bat. Usage graph), as well as wakelock detector. Another alternative would be better battery stats. What you would need to observe would be the apps and wakelocks draining your battery both when you are using your phone, and also when its idle.

I also notice that battery capacity is 2A in which it should be 3.140A right?
this shows on kitKat but on jellybean, it's 3.140A again.
is there something wrong with the detection of battery capacity?

What happened was that in kitkat, the permisssions required to be able to access battery stat files changed. Thus, apps w/c could freely access the batter stats in JB cannot gain complete access in Kitkat. This is the case for some battery monitor apps w/c now have lesser accuracy in reporting battery. No worries though, as there are means to bypass this problem. If you have xposed you could install a module for this. Also, some apps like gsam battery monitor come with a separate root companion app. Once you install those batter stats will be accurate.

Here's a screenshot of my battery stats for today..might not be 5+ hrs of screen on as i did a lot of rebooting today (themed with g3 tweaksbox). Nevertheless, this is just to show that kitkat has the potential to provide good battery life. Also enclosed is a screenshot of one of the battery apps i use, gsam.

Hey everybody! I have some findings I absolutely must share so you can benefit as well.
I've been doing some tinkering and I've find a way to significantly increase battery life on the OGP.
First thing you'll want to do is put your phone into airplane mode.
Second, turn your screen brightness down as low as it will go. I mean, all of the way down.
Third, don't play any games on your phone.
Try those three tweaks and see what kind of battery improvement you get.
Unfortunately, Camera has stopped.

Just so you know, first my cell radio and wifi were both on the whole time. Second, i was on auto brightness the whole time. Third, i played clash of clans as you see in there.

If you have not done this already, adjust your cpu to save your battery juice. Set the cpu governor to powersaver or interactive mode if you just using the phone to send msg and make calls. I let my phone run on msm-dvcs and when I'm not plug in. Check out ROM toolbox if you're rooted. Seriously folks, instead of complaint about how much the roms suck the juice, try these different ways to see they make any difference for you.

That's pretty much a tablet use. You want great battery buy a zero lemon battery, the bulk is worth it, I got 3 days with very heavy use

I found a way to make my phone last a long time. I just turn my phone off and don't use it. I wish I would have though of this sooner.
