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.

[Q] Megaman Legends 2?

How does it play on the Xperia Play? I am getting so tempted to by this device along with the Mugen 3600mah battery and 64 GB micro sd. Anybody else have this set up with extended battery and sd? How it is for daily use also hows the battery life? Hows netflix on it?

Battery life on the Xperia Play is not good. You can get a day of use with moderate usage. It drains a lot when using wifi and playing games.
When you play HD games like GTA 3, Shadowgun then your battery is gonna drain like hell !
I was expecting better.

Lol? I optimized my device so much that the stock battery lasts like three days. The battery life on this thing is amazing, just use it wisely and optimize stuff.

What do you mean by ' optimize ' and how long do you charge your phone for ?
And do you play games on it and use wifi heavily ?

I have wifi constantly on but use the the general mode on both juice defender and easy battery saver and don't even get a days usage really (although I did just reinstall easy battery saver today). I haven't even played on any games. That's quite bad I think so what could I do to improve this? Not rooted
Sent from my R800i using XDA

Nothing too serious, i'm quite a noob at this stuff (first android device). I just rooted, cleaned the bloatware, frozen other stuff like the stock launcher, installed a very light launcher, disabled the boot animation (boots so much faster), did the adb setinstalllocation 2 trick, and a couple of other things. I mean, i always have low brightness and i only have wifi on when i need it, but i do play games. Of course the three days mark is only achieved when i don't play, but it definitely got even more awesome than out of the box (even there, it rocked, at least for me).

Anyone know if Ice Cream Sandwich update will improve battery life ?

reply to youngronn
I actually run the exact same stuff you wish to purchase, and i can kill the phone in 1 day if i play castlevania, symphony of night for about 11 hours straight, other than that for an average day of minimal use, maybe a half hour web browsing or so its drains about 6-7% in the approx 10 hours off the charger.
this is overclocked to 1.5ghz with a slight undervolt. the 64gb microsd works fine, i have aroundabout 10gb left free on it, as does the majority of psx emulation using fpse, n64 is a bit more spotty, everything older runs 100% perfect.
i cant comment on netflix because it isnt available where i live.

Confused...The title of thread is mega man legends 2.....so where is this game available for Xperia play? Is it on an emulator or gameloft?
Ios suckkss.

I just finished playing Asphalt 6 HD for 15 mins and I lost 16% !
So if was to play for an hour my phone would shut down right?
How about that right? How can this happen?
Why me?

Thanks are you running on the 3600mah battery?
And its a psx game ran off the emulator to the guy asking.
Also is there a compatibility list on this forum for PSX and N64 games?
I've searched and haven't seen one.

Most users who are saying that are saying that their battery lasts for 2 days or more are those who leave their xperia play on standby most of the time. Only use it a little bit here and there and a bit of gaming. Or are using a 3600mah battery.
In no way can you get 2 days of gaming full whack usage from the stock battery.

Played 9mm HD on stock GB 2.3.4 no overclock,oem stock battery
with 100% brightness,Wifi On,Multiplayer online,no data (airplane mode)
after 3- 4 hours of non stop playing,then it's shut off.

no,i didn't use anything to improve my battery life.
seriously,the battery are good to me,compare with my previous galaxy s2,xplay will give you aproximately around 30 min -1 hour more life.
i saw your post about battery life in another thread,but i forgot which is was.
seriously,maybe there is something wrong with your device/battery.
xplay does really have good battery life,at least for me.

[Q] How to super Optimized Tmo Sammy S2 for best battery performace?

So I switched from the iphone with edge to the Tmo S2 with Jugg 5.0 ROM + Go Launcher. I really appreciate the 4g speed. However, the overall experience is not as smooth as the iphone and the battery life sucks big time. I normally have to constantly plug the phone in whenever I can. It works ok when I'm at work but when I'm out all day my battery won't last more than half a day. It's so bad to the extent that I have to turn off my phone and turn on when I need to call or text so I can keep the phone alive the whole day. I tried Juice Defender but it didn't help my battery at all.
Yesterday I spent a few hours on XDA and I came up with these solution to my battery problem:
+DarkSide Digital Warfare v2.7 ROM (couldn't find 2.5.1 version)
+Flash Synergy Kernel over (supposed to give better battery)
+SetCPU app (auto detection)
+Zeam launcher
So far, it seems to be better on the battery. Is there anything else I could add to make my battery last longer? I need the phone to last at least the whole day without charge. I'm constantly on 4g looking up stocks, reading news, email, google voice, grooveip, facebook, turn by turn navigation, music, netflix, youtube ...
Thanks,

Welcome to Android.
From what it appears, you seem to be a heavy user. The most you can get out of a Android device with heavy usage is 3/4 of a day (14-18hrs) tops.
You have 2 choices, either you travel with the power cord not to far away and plug it when you need it or you invest a whooping 10$ and buy another battery.
There are tricks to keeping your battery healthy but lasting all day as a heavy user will be very difficult.

If this is a new phone it takes a week or so for the battery to settle in a hold a charge well. After a week or so you'll notice your battery is lasting longer. Also make sure that nothing is keeping your phone awake 100%. Some apps don't play nice and cause issues. Welcome to Android.
Note: navigation kills battery fast, when your using it try to plug into a car charger or something.

There are a lot of things you can do to improve battery.
1. Juice Defender (which you say you have already tried)
2. Limit the number of widgets you run or run no widgets like I do
3. Turn the screen brightness down all the way
4. Don't use Live Wallpaper, also, try to pick a dark coloured wallpaper since white/light colours seem to use up more battery.
5. Uninstall apps you don't use.
6. Turn off GPS unless you need to use it.
7. Turn off sync completely or only have your gmail sync. I don't need to be notified when I get a facebook message so I don't need it syncing every few minutes or every hour, I can check that manually myself.
8. Turn off animations.
9. Close background apps that are running that you aren't using.
10. Use Task Manager to close open apps when you are done using it. Task Manger is your friend.
11. Enable Power Saver Mode.
etc etc.
Those are the main things that I tend to do. I plug my phone in every night before I go to bed as well so I am not sure how long my battery actually lasts. But typically after 16hrs of use I still have 60% battery when I go to bed.
Currently my phone has been on for 7hrs 15mins and I have 87% battery. So you can do the math. I am not as heavy a user as you seem to be, but hope this helps. Peace.

Check out this video it helps show you how to save battery. Enjoy!

Thanks for the inputs guys. I should have said I was looking for Rom/Mod/Scripts/Apps... that can be flashed onto the rooted phone. I have done all the basic battery saving housekeepings as listed by Chochiwpg.

You could run Juggernaut with Faux Kernel and Gideon's battery scripts. Or Telus T989D stock ROM lightly tweaked with same kernel and script. Got good results on those as well. Good luck.

Btw, has anyone had tremendous increase in battery life using the after market extended battery?

If you are talking about extended batteries that don't require a custom enlarged back cover, you will not get the battery increase that you are looking for, not even close. I cannot speak for the heavy duty ones that require an enlarged back as I do not own one

Gideon's scripts are great with Juggs. Underclock it as well like 384-1080 is a great setting. Also let die all the way down and charge all the way up and repeat for a few cycles. And don't stare at your phone every few seconds either lol! Another thing are the notification lighting buttons at the bottom. Drop to 1.5 seconds.

I have the extended 3800mah battery. It's insanely fat and makes the phone look hideous. On top of that I really don't feel like the battery lasts all that long at all. It's in my pocket all day at school and by 3:30 I'm at 35%. This thing cost me 65$. Total ripoff. I'd suggest spending 20$ and buying two more regular batteries. See what that does for you all

A few things you can do on ANY ROM to improve battery life.
*) Decrease screen timeout to the lowest possible setting.
*) Adjust screen brightness to the lowest level you can tolerate.
*) Decrease the backlight key timeout to the lowest setting ( or off if you have the option )
*) Be sure to only have wifi and gps on if you are using them.
Those will help quite a bit in general however, a ROM like Juggs is meant to really take advantage of the power of your device so its probably wise to move to a different one if max battery is your goal. I love Juggs but had to move on to the AOSP stuff. Also, heed the advice above, allow the ROM a few days to "settle" before making a switch or even a judgement of its performance.

Thanks for the replies guys. So my phone lasted for 9hrs today which is a little bit of improvement. I was streaming netflix for half an hr on the train on the way back home so that may have drained the battery. I have just installed JD, will post back how it goes tomorrow.
So the extended battery is a no go eh. I really don't want to lug around a few extra batteries. I want to carry as little as possible. I normally carry my phone and my ipad but now I tend to not use the ipad much now because the S2 screen is pretty gigantic for a phone.

I know the point was already made but just to reiterate, you can get 2 Anker extended batteries (same size as regular battery) and a universal charger for like $20. This will leave you with three batteries. One for the charger, one for the pocket, and one for the phone. With this system its pretty easy to always have one full battery ready to go and one charging. The battery is small and can just go in your pocket, or maybe even in your wallet depending on your preferences. It solves the problem completely. I don't think you are going to do much better because if you are a heavy user then your battery is going to be used because your phone isn't going to be sleeping.
Good luck.

If you read my post above. I'm against the idea lugging around too many things. It's also a hassle to swap the battery and keep them all charged. I may be a heavy user but it's not like I use the phone all the time. I use the phone heavily early in the morning on the way to work and after 5pm on the way home after work. The commute each way is roughly 45 mins. In between the commutes i make a few calls and texts through GV. I don't think i'm that of a really heavy user.
Anyway, it's noon and I'm at 75% with JD on and setCPU to 384-1084mhz which is pretty promising.

Questions go in the Q&A section

Since you changed kernals, you aren't going to benefit from TDJ's battsaver script you can use with the stock 2.7 kernal.
Go lower on the max frequency. Something below 800 mhz. Setting a negative gloval mV doesn't hurt, and if you can get to -62.5, that's great.
Oh, and when using data, try GSM only...
To be honest, the larger problem with battery life is typically the user. There's no real magic on making the phone last longer other than using it less. If you're going to be power using the hell out of it by using 4g for hours streaming media, your battery is going to be ****.

Don't you think it is ironic for me to switch from the iphone to the S2 because I couldn't stand the slow 2g Edge connection then have to lower data speed to GSM (2g) just so I can use the S2 long enough?
I think the S2 is one heck of a device but the OS and Apps are not running very efficiently.
I tried the ICS ROM ARKSIDE.UCLE2:: x[BETA07.1] in the last 2 days with setCPU at 384-1026Mhz. I have had great battery life. I got home at 12 am yesterday with a 2% battery. Today it's been 7 hrs on battery and my battery is at 70%. I don't know if it is the ROM, setCPU or a combination of the two but I'm pretty happy with the phone right now. ICS is awesome too.
I highly recommend that solution to anyone having a short battery life problem with their S2.

It is a little ironic since you did bring up the comparison. What I was attempting to do was to bring the phone more into spec of an iphone to get similar battery life. You're probably going to even get better runtimes due to the battery having a much larger capacity and better screen technology. All that superior hardware packed in the t989 is going to need more juice to run.
It's great you're getting good runtimes now. From my personal experience, once I drop down to the single digit percentages, it starts lasting a lot longer per percent. If you wanted to squeeze all you can from the device, those 2000mah aftermarket cells might add another 15~30 minutes.

You have an app that uses the cpu too much = it eats a lot of battery.

Yea true! Some app is sucking the juice off your battery! See if you have some background app running which is trying to connect to the Internet (Since you have both data n WIfi off). Usually these apps eats up a lot of CPU speed. Could explain the lag issue too
Also does you phone heat up?

Great battery life on this phone. Better than most I've tried. Watch what apps you have installed as well. They might be tapping the juice in the background.

and if u use swift key x thn think twice it uses more thn 3mb ram when u nt using 50+ whn ua using
soo think ovr it
dnt keep screen brightness to max
it will drain juice twice faster whn ua at home keep it low and when out 25% is enough to make u see the screen in bright daylight

Yes I must point out that the battery life on this phone as I have observed is quite above average.

I definitely agree on that. At this day and age of smartphones and their battery lives, this phone is rather exceptional.

Use apps like Watchdog and Wheres is my droid power to check what is using more cpu/battery! And remove it or find a alternative

Its always better to install apps which are without ads (mostly freewares are like that only). Keep the brightness at optimum coz its the screen which uses most of the battery.
The more the softwares are running at a moment, the more the RAM is used and hence the battery runs out qiuckly.
Dont keep wi-fi or internet connectivity open always.
Or else u can install third party softwares like Juicedefender or Easy Battery Saver.

Oh and most importantly NO TASK KILLERS!

Or you can install the program AdFree, set the adress ip for ads to be ignored and you will have your phone ad free .
And those softwares "juicedefenders" are good on a short term but on the long run it causes problems.
Use it as stock without any programs that help you to have more battery or **** like this..

Check the battery usage through Settings > Power > Battery use.
No need to use a third party app for this (unless you've removed this by any means).
Sometimes software issues cause these problems on the phone (even on the stock ROM). Common culprits are "Phone is idle", "Inactive" and "Android system". If these are reporting battery use above ~10% (and you haven't actually had the phone inactive for most of the time), the problem should be resolved with a factory reset.
Otherwise, unless you've tampered with the bootloader this would be covered under the 24 month manufacturer's warranty (12 outside EU) and the device should be sent in for a battery swap / given back to retailer as DOA.
Also, the device isn't the fastest one. The processor is running at 1Ghz with 512Mb of RAM to go along with it. The solution is to load a kernel with overclocking capabilities (Titanium for example) and crank up the CPU to 1,5 or 1,7 GHz. I would assume all of them can run 1,5 GHz as I suspect the processors are actually underclocked to keep battery life long.
Obviously this would reduce your battery life, but having less than 24 hours of battery life on an unmodified One V is what I would call poor unless you are a heavy user.
I hope this helps.

Actually, a good kernel can improve battery life even if you overclock your cpu. HTC's kernel doesn't come with all the tweaks available for volting and battery life. So if a good dev makes a good kernel, the battery should be the same as running on stock, but with faster performances. Adi_Pat has done a great job with his kernel. I was running it for 2 days until I needed to get a replacement for my phone and now I am waiting to get a new one so I can run it again. I even overclock it at 1.9 ghz and run it for 1 full day and after almost 8h of wifi on, the battery still had 50%. So if you don't have an app that kills your juice, you have definitely a poor battery built in.

does it lag
it was going to buy this phone but saw this vid /watch?v=JptIYZl8qmE that said it was very lag. do you think i should buy this or the sony arc s. plz help

I had some similar issues until I did the following:
Run the battery completely dead until the phone shuts itself off, then put it on the charger with the phone off. Charge it until it is at 100%. Take it off the charger and turn it on. Turn it off again, put it back on the charger until the LED is green, then turn it on again. This helps Android to calibrate the battery.
Install Quick System Info and see what apps are running and how much resources they are using. Also, close all apps, then go into Settings>Apps>Running and see what is running. Look for any apps that shouldn't be running and uninstall them. You have something running in the background and need to get rid of it, this will help you do that.
Uninstall Swiftkey X or Thumbs Keyboard or any other keyboard apps you put on there. Uninstall any weather/clock widgets like HD Widgets or Animated Weather. Use the stock keyboard and stock weather widget (they both work pretty well).
After doing all of this I consistently get home after 10 hours from work with about 60% after moderate usage. I also have almost no lag unless I am playing a more graphically intensive game. Couldn't be happier.

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.

How could you undervolt that low? It doesn't freeze your phone? At what frequency did you undervolt this low?

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.

is there any apps that will actually improve your battery life at all? currently being rooted and have the pacman rom flashed to my gsm version.

You can also try One Power Guard:

With juice defender is it possible to have the icon in the status bar, but nothing in the notification drawer?

You just have to try and see... Hopefully this app will work also for you... :fingers-crossed:

"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.

Source?
Also stock ROM gets quite laggy after some time.

It's all over xda. However, here's a link:
https://plus.google.com/app/basic/stream/z13dgb0rksywh3muq222fzkqnwfgdbgrk04
It's from Dianne Hackborn, android developer for Google.
from here

Root your phone, put kernel titanium kiss, make it with 1.2GHz and smartassV2 cpu governor and than flash with full wipe myOneV 8.0 rom, put display brightness to automatic you will have stunning results.
P.S. make back ups to your data but do not restore it all from recovery
