I have poor battery life on my desire, it barely lasts 7 hours. I have tried wiping battery stats etc, and have the screen brightness at 50%. I have read that some kernels can greatly improve battery life, is this true? If so, which would you recommend, and do I just flash it like I would a rom? I am using the latest miui.
Cheers,
Steve

They can but finding the underlying app causing the phone not to sleep would be what I'd be looking at. Remove all installed apps and add them 1 at a time and see how the battery goes

Yeah i've tried this, there's nothing draining the battery.
Not at all
Such battery drainage can only be induced by either heavy usage, or phone not being able to go to sleep.
The differences between kernels in custom roms are merely a shades since all of them are pretty much battery efficient. You won't miraculously jump from battery life of 7 hours to 30 hours. Concentrate on your apps or even better, third party Widgets.

Probably a hardware fault then - the OS on it's own with no apps installed shouldn't drain a battery that quickly. Did you also turn off the sync options to test that theory?
Personally sounds like a knackered battery/phone
If it isn't apps/widgets (they are the culprit for heavy usage) then it would prob be a faulty battery. I did a little test last month to see how much battery I could lose in 24 hours. I lost 8%. I guess it could be a baseline to start off with.
Hello everyone, I lately have been getting horrible battery life!! I keep brightness on lowest setting, use wifi when possible, turn down haptic feedback all the way etc. do my best to save battery!
So my epic is Rooted with CWM3, and the latest frozen syndicate rom installed. Is it because my phone is rooted and the syndicate rom drains it more? is that why i have bad battery life? Does having your phone rooted drain battery life?
I ordered a Seidio 3300mah battery and got it yesterday in mail. Put in phone, then charged rest of night about it. Im using it today and am still receiving poor battery life, my friend who has epic ordered a cheap hong kong battery and is getting better battery life? I read something about conditioning your battery and draining it to 0% then charge fully to 100%? How does this work please explain?
Can someone just please help me use my new battery to its potential and help me out here?
Draining your battery for battery calibration is unecessary... there are a few threads regarding it...

so what should i do to improve battery life?
Rooting and custom ROMs reduce battery usage. You need to supply more details. Are you overclocking...that burns up battery usage. Have you tried Spare Parts to see what is using your battery? Has 3G been out in your area and the phone is searching for a data signal?

I have noticed no difference in DK28, EB13 or EC05 in my battery life. Do the calibration suggested in the post above. As for ROMs it is about personal choice. I have been with Bonsai for awhile now. I hear the ACS ROMs are very stable. Syndicate Frozen is good, Midnight is good. Read the OPs, learn what they remove and improve and see if that is what you are looking for.
Running SRF 1.1, with a custom theme, brightness at lowest setting, haptic feedback all the way up, because I need to know if someone is calling, I regularly get 30+ hours per charge. The two Chinese knockoffs I have get about 26 or so hours per charge.
I have recently seen a drop in my battery, spare parts on a couple of occasions should my phone would not sleep. Sometimes a reboot would fix this, but reflashed just to be safe.
After the reflash I was still getting bad battery life but spare parts showed no issues, so I started doing the airplane toggle again and that seems to of fixed it.

whats spare parts?
Spare parts is a free program available in the market place. It shows you more detailed statistics on what is using your battery juice.
Undervolting maybe. But I got stablilty issues. ymmv anyway.
My advice is
1. Set max clock to 800mhz and min to 200mhz. The CPU is volted -75 over 1ghz and 200 is volted the same as 100mhz. I use the Conservative governer but Ondemand works well too.
2. Get a good custom rom/kernel. CM7 and Frankenstein got the best through all my testing.
3. Brightness at lowest, turn off "Notify me when Wifi networks are available", Turn off syncing for contacts, the two GPS options, etc.
4. Take out as many applications as possible(Personal preference. I think it makes a difference) But I mean stuff you don't use. I take out Bluetooth, GPS, DRM, SNS, and most stock applications. If you're using Handcent you don't need stock SMS and vice versa.
5. If you're on 2.2 and lower I recommend a program like JuiceDefender to turn off 3G when your screen is off. The latest update on the free version removed the option to filter applications using data while the screen is off.
6.Enable Airplane mode on boot up. Then turn it off and use normally. TWS
7. Definitly calibrate your battery.
8. *Insert unreasonable battery tip here*
Oh and spare parts can be installed directly from the market. It's a program that allows monitering and for changing animation speeds and such. I don't use it for anything. You should also be able to go into settings -> about phone -> battery usage and see most of what spare parts would.
is tht one thread the one guy posted to calibrate the battery? will it work?

Especially with a new 3300mAh battery! I recommend the top two as the third didn't work for me.
Juice defender on aggressive mode and setcpu on conservative mode increases my battery life when on standby quite a bit.
Don't drain your battery to zero it destroys our batteries. Don't use juice defender. If there is no reason that you need background data on like when you are sleeping turn it off but some say that's cheating but their idiots. That will dramatically improve your battery alone. Do the airplane shutdown every once in awhile some that's cosmetic but don't believe everything that is told to you. Only keep apps installed that you regularly use. Use spare parts to see if any app is causing significant drain. I'm a battery life guru.... ;-)

Hello all,
Am i the only one that is having problems with the battery life on the galaxy gio?
I charged the phone today at 5 in the afternoon, by 8(3 hours after) 70% of battery, charged it with the wall charger and i rebooted it when the battery was full to close all tasks.
In 3 hours without any wifi, only 1 sms received, no calls and no other tasks was executed i lost 30%.

What rom you have ?
I have problems with battery life too...but because i play games. Is weird because you didn't do nothing like browsing or play games and your battery was eaten.
Try a full wipe.
Also search the market for PowerTutor, it might be able to help finding what eats your battery, as what you describe this is not normal.
If you've rooted your phone you can calibrate your battery. There's an app for this in the market. It just wipes the battery stats file and creates a new one. I've head that it is good with every rom change to calibrate the battery Hope this helps! GL!
Actually it's good to flash every new ROM when you have fully charged battery. If you fail to do this you'll have to calibrate the battery and it might not be easy to do right the first time.
SO much easier to flash having full power
Battery stats wiping
IIRC google denied that battery stats wiping would actually increase the battery life: http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/
I assume, you have things like WiFi, BT or GPS turned off... Then you maybe might try another launcher. Samsung's TouchWiz is quite a power eater.

It won't increase battery life, true, but think - when you unplug the charger? When your phone says "100% charged", right? And if your battery starts are wrong the phone may say "I'm charged" when it's actually, say, 40% charged or whatever.
Wiping stats should also provide more accurate battery indicator when it gathers new stats after some usage.

In my experience the battery indicator may work a bit odd (e.g. it goes fast to 40% then stays there for ages). But it didn't keep the battery from charging to full, even when it indicated 100% it still kept charging. But to stay in the topic, clearing the stats might help the "dropping by 30% really fast" issue
Yup, that's what I was talking about - wiping stats won't improve battery life, but might fix indicator accuracy
It could be your background applications eat too much mobile data. Check out your background applications and disable them. Stick with 2G also it improves battery life a lot
if the phone and battery are ok, and you don't have Wifi/BT/3G/EDGE/max_screen_brightness/ or high CPU usage background apps, you should get something like in the attached picture:
AT least for me CM7.2 really improved battery life up to 2 (TWO) days!
Unfortunately CM9 ruined this again and brought it back for ~8h...

You can use CM 7.2 http://forum.xda-developers.com/showthread.php?t=1381355
It is stable and saves battery better than stock rom.
Another thing to check is that Wifi is set to disable when the screen turns off or when plugged in... If not, you can loose 50% battery life in 6 hours. (Which i did once. NOT FUN.)
As well, apps that sync in the background. Ie, mail checking your inbox every hour for new mail; facebook, twitter, myspace checking for new notifications every hour; leaving apps using GPS running in the background like Navigation, My Tracks, etc. Those sorts of things can drain a battery really quickly, beacuse it has to wake up the phone, get the phone to get the required data over the cellular network then go back to sleep again, instead of just letting the phone sleep.
Another thing you can do is to make sure you kill apps. IE, don't use the home button to exit the app, use the back button. That will kill the app instead of leaving it running in the background.
Its kinda funny, this is all stuff people have mentioned already, but it seriously can be the difference between a half a day and a whole day on a battery...
Hello all together
I'm browsing xda for a little more than a year now. You guys helped me a lot!
First I want to apology my english, I hope you understand what I want to say
Not a long time ago the battery of my WFS lasted up to 3 days (incredible if I think of it now).
That was with a self rooted stock rom and some changes (bravia, turboboost script, oc-kernel, etc.).
Out of nowhere I had problems with my calendar.sync.provider. Processes htc.bg and htc.bgp used the most of my battery (found out with Battery Mix).
I could watch the percent falling... Battery was getting very hot.
After i killed calendar.provider and calendar itself those bg-processes disappeared and all went back to normal.
Installed m1nd's rom, tried a lot of different settings, used calengoo instead of normal calendar (uninstalled the other)...
But battery life was never the same since then.
We also had a really rough winter and I was outside a lot. my battery began to drain faster. First I began to install apps like "auto wifi toggle" to stop that battery drain, after all I just bought a new battery this spring - 1500mAh.
But other than i expected - battery life did not increase. So I decided to install CM7.2 (wanted to do it anyway - great work btw!).
And guess what, nothing changed...
You will find some screenshots at the end... (did barely use the phone this 4 hours)
So what can I do? I'm desperate. The battery does not hold the whole day...
Please give me some tipps (if you have others than the general battery saving thread) or at least cheer me up
tl;dr: Phone works for 10h (mail,text, no phones, no games) - Changing battery & ROM does not fix battery drain...
Thank you in advance!
it happens to me too unfortunately, i charge it everyday or every 2 days
when i play a small mini game for a few minutes, battery drains like over 10% in a few minutes.

Sent from my Wildfire S using XDA
Thing is, I charge my phone everyday. And I've been using CM7 or CM9, battery life never lasts more than a day. If it's only lasting 4-10 hours. Check your sync settings. Keep it only on 2G networks if using data. Get a battery saving application, in my opinion, it sounds like your using a lot of mobile data/wifi.
I hear it all the time... Does this rom provide good battery life? How's the battery life? Why is my battery life suck? So; it may have been done already somewhere; but I figured after watching and logging my own battery life, I could really help some others. I'll section this out; no specific order at all.
ROM: No matter how many times I look at a ROMs thread, I get to see a multitude of "How is the battery life" posts. You know it, I know it, and we all know it. Truth is; after using plenty of ICS roms out there; most of them have similar battery life. Currently I'm running the Blu Kuban rom, and I get just as good battery life as I do with most other touchwiz based roms. To each rom their own. Read up on the rom itself before you go blaming the rom for battery life. I've noticed the JB builds aren't the best with the battery, but we must remember those are usually noted for having bad battery life. Either way, most of the ROMs I've used personally perform rather similar in actual battery life.
Kernel/Governor tweaks: I can't stress this enough. Governor's and Kernel Thread. That thread will teach you more than anything you want to know about kernel and governor tweaks. Some of these governors can send your phone to absolute battery immolation, while others can set your phone up to last 2x as long. I prefer the more conservative approach and end up with a ton of battery left at the end of the day. While these settings are important, the most important is yet to come.
APPS. I can't stress this enough. I used a quite a few different setups to find what all really uses battery, what doesn't, and what I should to to maximize my own battery. For those of you who don't know me at all, I work ten hours a day, and I used this time frame to measure the battery usage while it's sitting in my car for ten hours. I have a Trexcell 3800mAh battery, so it's roughly 2x the power as the stock battery.
What's the number one usage on my device? NOTIFICATIONS! All of those apps that automatically feed their greed by getting updates from the servers or whatever. Facebook, Hotmail, Tapatalk, and EVEN just the gMail app could drain 10% of my battery in ten hours. Let me show you my findings.. These are the normal apps I use that can automatically update over certain time frames.
Hotmail
Tapatalk (Xparent Red version)
gMail
Facebook
Now if they all automatically update on the stock settings, ten hours of work will mean I'm coming back to a phone with only 75% battery. With only 4-6 hours of deep sleep! That means these apps are waking my phone up to do whatever they want for quite a while. With all of them set to be manually updated; I come to 95-97% battery life. That's quite a stretch in a difference you know?
So, I tested each with the others off and here is what I found. (I tested for three days, wrote my results for each day, then switched to a different app)
Hotmail set to update hourly would leave me with about 90% of the battery at 4:30. Average deep sleep times were in the 8-9 hour ranges.
Tapatalk was setup stock for 15 minute updates. I'd lose at least 10% on the battery every day! Deep sleep however would range in the 8.5-9.5 hour range.
gMail was set to update hourly and would leave me with 95% each day with only keeping the phone awake for 30 minutes on average.
Facebook updates are odd; since they don't happen all the time. So I had a good friend post on my wall three times a day and noticed that it would eat a LOT of battery, usually 10-15% and keep my phone awake for about 30 minutes a pop.
Now I must note, for my tests I had almost nothing installed on the phone aside from the apps listed and the basic apps available in the blue Kuban rom. For the tests, I set google voice to do not disturb so phone calls and the like wouldn't be an issue.
With all four of the apps set to default updates however (no messages on facebook aside from one day), the battery life ranged from one day being 67%, second day ended with 74% and the third day left me with 72%. That's a LOT of battery for just sitting in my car.
After these findings, I've switched all my apps to update only when I manually refresh them, and I'll tell you what, my battery life has never been greater. I literally come home with 95% battery on average and can sit and play on my phone almost all night without charging until it's nightly stay on the charger.
Just some other tips I've learned along the way.
Wifi is a battery slaughterer if it's not connected. Driving around the city and having the wifi detect all kinds of networks is just battery slaughter. So, my rule of thumb now is, when I leave the house the wifi goes off. It's true that wifi uses less battery than 3g and 4g, but when you're picking up random networks and the radio is searching through them, it's just no good for the battery.
Brightness, it's a key. I can't stress this enough, if you don't need 100% brightness and want better battery life, turn that screen brightness down to an acceptable level.
As an ending to this short but sweet little tidbit of information, I'd like to share why I wrote this, did all this testing, and why it mattered to me since I have an extended battery. My phone is my link to the world, my family, potential jobs, and just my favorite handheld entertainment device. Me and my fiancee` both have the E4GT, and I have the extended battery. She has the stock battery and it doesn't last long at all for her. So my plan now is to work with her on her battery life, and give her this extended battery. I won't need it since I literally have to try to get to 50% battery life with it. I usually end up plugging my phone in for the night at 65-75% battery. I just figured I'd share this with people on the forum as maybe a different approach to saving some precious battery. If you like it, tap the thanks button. If you have any ideas to better this, let me know!

I understand leaving your phone on all day long so you can see texts and missed calls and stuff but why not just turn off your data during the day instead? I use this widget when I am in a poor signal area, don't need data, or sometimes overnight https://play.google.com/store/apps/details?id=com.farproc.data.enabler&hl=en Simple and effective and you can let your apps sync for times when you are using the phone
Undervolting also helps a little
Step 1. Install CM10 or ParanoidAndroid.
Step 2. PROFIT!
Battery life between stock and AOSP is night and day.
The questions about battery life are there because not every kernal is the same. Especially ones that are early in development. Pretty much every AOSP rom will defer some amount and even more so if 1 of them is in its early stages.

What most people need to know is no matter what tweaks are applied.. YMMV. It's all down to the user.. Best way to save battery on your phone.. Turn it off!!!! lol But I agree with the things posted. I'm always messing around to find the best settings.. So far i've gotten over a day (1d 3 hours) with over 2 hours screen on with my setup. Which is great for me. But all in all, it's how i use my phone.

I wanted to share some of my thoughts and experiences with battery life on my E4GT.
On GB I had great battery life...As soon as I got on any version of ICS I started having battery life issues. I eventually learned that my battery was buldging so I ordered a new one. Once I got my new battery, I thought life would be grand...NOT so much!!
Over the last month or so and ROM after ROM, tweak after tweak and even going straight stock I figure it was actually the device itself that was the problem...AND it was the problem from the day I got it last Dec. From reception to battery life to buzzing camera.
Something I've seen as is that "freezing" an app doesnt always disable it...I've had to completely uninstall something to get it to not run...even though its frozen and all of its startup references are disabled in Autostarts.
I dont care for the stock browser, but I've learned that 3rd party browsers such as Firefox and Chrome continue to run and use CPU even after exiting...Now, FIrefox has an actual "Quit" option while chrome doesnt...So if you Quit out of Firefox its ok, but unless you close your tab in Chrome it just keeps on chugging battery power.
A TEP replacement phone is what finally resolved my issues!!
I've only had my new phone for 2 days now, but I'm already seeing better battery than before, plus better reception and a camera that doesnt buzz.
I've got Agats ROM with the BluKuban 1.8 Kernel. This Kernel has a few more options enabled so I use that but I like how Agat put his FI27 ROM together.
Thanks for reading...
