Sorry to post another thread, but I'm just curious...
My battery life sucks I can barely make it through the school day without my batter dieing. So anyone got any suggestions that I could do to get better battery life?

Shut it off. Your at school.
If your flashing roms just make sure you charge to 100 percent and clear battery stats in recovery/advanced.

Sorry bro. Do you get good battery life? What does wiping batt stats do?

uh what. stop being an asshole. you didn't help with anything.
OP, battery life depends on a lot of things. Go to settings>phone info>battery usage and it might give you an idea of what is using your battery. Maybe you just need to turn down the brightness on the display, or turn off some things like Bluetooth or GPS.
Wiping battery stats will simply delete a file that caches some things about the battery. Sometimes when flashing different roms and themes the stats can get messed up and they need to be wiped.

Quite possibly a bad battery. Your battery shouldn't drain when the phone is off.

Does it drain when the battery is removed from the phone?
Sent from my LG-P999 using XDA App
you should download a cm7 nightly my battery lasted from 10pm - 9am with 30% than i put it to charge
You can either do a factory reset or NVFlash CWM and flash a ROM to see if that fixes things. If not, then defective battery.
What these guys are saying is most likely, especially with that kind of drain. But also make sure you don't have any crummy apps, it apps that run when your phones off. Ex. Some weather apps run in the background and draindrain

You guys. He said that his phone was OFF while the battery lost its juice. It has NOTHING to do with what ROM, KERNEL etc etc he is using. Now for the op; simply just get a new battery and check if the problem persists.

Haha, yea. Read to fast, selective reader I guess. Thought I saw 'screen off' =)

Try the same test with the battery completely removed.
If it doesn't drain that fast - Then the phone is not shutting down properly, and most likely is the result of a nasty app.
If it does still drain that fast - Then the battery is probably faulty.

In your original post when you said you turn the phone off at night, you do mean actually turning it off right? Like shutting it down and not just turning the screen off, right? Just making sure we're all on the same page. If the phone is powered down then it can't be an app because apps can only run when you're booted into Android.

I would try to eliminate apps one by one. Freezing them with titanium backup or using better battery stats to see which apps have a lot of wakelocks. I had the same issue before.

Then its the battery. I had the problem with my g1. I would load the maps and use gps. It would say my battery is around 70% then after like 5mins the phone would get hot and then it would say i was at 30% or lower. Swap out for a new battery and it didnt do that anymore.
My g2x is kinda doing the same thing. But its a little slower. I turn the phone on in the morning 100% battery. Then use it for about an hr. (95-80%battery) put it in my pocket. Then about 2hrs later it at 40-35%. And the phone feels warm.
Also check your battery to see if it had a lump on it. If so then its a bad battery and needs to be replaced asap.
I ordered a replacement on ebay should be here by next weekend. Only $4

I don't think its the battery in this case.
Sent from my Flashback HC-TAB using XDA Forum App
I had a problem like this and still do at times. Part of it was the stock kernel I was running and the other part was the fact that the phone was not fully going into the low power state it was supposed to. I now only loose about 5 to 7% in the worst cases. That is better than the 20 to 30% I was loosing before.
I recently rooted my phone (last week) and have been getting into flashing roms. However i just read something about battery calibration. It basically said you should calibrate your battery after every flash so that you get your full battery life. (also said the battery itself is not being calibrated but the way android reads the battery is being calibrated)
is it true that you should calibrate your battery after flashing a rom?
if it is true, how do you calibrate the battery on the Infuse?
If there are more than one way to calibrate your battey, whats the best most efficient way?
Thanks in advance to all who help

Someone else might chime in on this, but I there is an option under advanced in CWM (red)(other colors ?) to wipe battery stats. Let a pro chime in first, I have not done it, just letting you know its there.
Thanks, now that you mention it i think ive seen that-its under advamced i think...but ill take your advice and wait for a pro to let me know if that works and if calibration is even necessary

I'm pretty sure I've read on more than one occasion that battery calibration is not needed on the Infuse...

Can anyone look at these screenshots and advise me on how I can get better performance from my battery? I just flashed SkyICS (latest version) hoping to get better performance from my battery, but it doesn't seem to help. This is with what I would consider medium to heavy usage. I used my phone most of the day to browse the web and check facebook.
Any ideas?
Yeah a bigger battery and some fairy dust

Bro heavy users like you and me can only get by by keeping a charger on hand undervolting underclocking
Edit: but 4.0 rom's don't have custom kernels yet
Sent from my SGH-T989 using Tapatalk 2
Looks like the screen has been on for at least 4 hours. All you can really do is underclock it and freeze all the stuff you don't use.
Guess I will research how to underclock.... any good starting points?

Here's a couple basic and obvious tips and you might already know this, but no one has mentioned it yet in this thread so...
Turn wifi off when there are no wifi networks to join, but I've heard not to let it sleep when you are wifi connected.
Leave bluetooth and gps off when not using it. I don't let allow any of google's location services to run in the background myself. Not sure how well that helps the battery though.
Some people say leaving off autobrightness turned off will help battery life and some say leaving it turned on is better for battery performance. I'm not sure who is right but you might try it both ways and see if one is better for you.
I've tried most of those things and they don't seem to help.
I'm in an area with lte but coverage is spotty at work. Could that be what is mainly killing the battery?

This is impressive battery life, if I may ask, what ROM are you using?
88% after 41 minutes of checking facebook and Google Reader? Is that normal? On wifi I should add...

There is no normal, everyone has different setups, different apps, and different lifestyles. If you're saying the screen has been on for 41 minutes, that seems ok.
Thanks for the help everyone. I guess I'll just keep chargers handy
Hi Guys
Well, after witnessing incredible battery life on latest HebMIUI (mostly taken from Pimp My ROM and Adrenaline Injector), I decided to make a flashable for the rest of the ICS ROMs we have here.
I must say I also use the LB6 modem which is known to give good battery life, so you are advised to install it too, but, it's your call.
I also add here AutomateIt app, which lets you decide what the device will do for certain events (open/close wifi/3G/4G/screen/charge etc.) which you can utilize to save battery life.
links to modem & sources:
SGH-T959W LB6 modem
HebMIUI ROM
PimpMyROM
Adrenaline Injector
AutomateIt
I take no responsibility for any damage claimed.
Tested on MIUI, AOKP.
Make a nandroid backup and flash it via CWM/TWRP.
Let it soak in for 1-2 days and let me know what you think.
Does this include the build.prop changes of hebmiui?
Yes. ROM name was set to Batt_MOD instead.
Installed on Remics without any issues. Will report back on the battery life in a few days.

Installed on aokp, on boot I get a process is not responding. After that it is fine and so far great battery usage.
i'll try it later.
Currently (CM9 latest rel), Sitting on a desk with full 4G on a 2300 mAh battery, I get about 2-3 days of usage. Plus a few calls and texts.
At school in and out of e, 4g, and deadzone, I get down to ~65%. Then I need to reboot to stabilize or else it will continue to drain at the rate and I'll be dead by the end of the day.
LB6 did nothing for my battery life but I was getting incredibly slow data, so I reverted to KJ4.
I am thinking of padding KC1 and trying it.

Yeah, I also experienced a freezing boot right after flashing on AOKP, but it happens only once & then everything is fine on next reboots.

Has anyone figured out how to not make the phones battery drain overnight? For me if I leave it unplugged overnight it goes down around 20-30%. I've heard that you can use the app setcpu to underclock the phone when the screen is off. Has anyone ever tried this with our phone?

Hi Pisher
AutomateIt is exactly for this cause. You can set it to close wifi when screen is off on a specific late hour and open when morning comes for example...

Your phone should be *sleeping* most of the time when you're not using it. CPU speed is irrelevant when sleeping. BBS is the best tool for figuring out why it isn't sleeping.
You might also look at Better WiFi On/Off.

hm, After I flashed this, whenever I tap on the "(i)" in the news and weather app that
comes with CM9 to see the temperatures for the day, it gives me a message that the
app stopped working and closes..
It might not have to do with this battery mod, but I am trying a process of elimination to pinpoint the culprit..
Would you confirm please if the News & Weather app works after you tap "(i)" in the top right corner?
Thanks..
Edit: I forgot to mention that I tried fixing permission, clearing cache & dalvik cache, but same results..
Hi
the only relevance to this app could be from the system\etc\init.d\S70darky_zipalign script.
Try with and without it and see if it helps.
