-try the bold text from the first post (battery calibration). It kind of helps, but you gotta do it about once a week.

- This helps me a lot as well. I have it set to -75v on all.

-juice defender is awesome. I have it set to the default settings and it really saves my battery.
I still only get around 10 hours battery life when I’m on campus (the wifi there tears through my battery for some reason), but if I’m at home my battery can last anywhere from 14 hours to three days depending on usage.

You could also have a bad battery. Take it to a Sprint store and have them test it. If you're still within your one year they'll get you a new battery, you may have to wait for it to be ordered.

[Q] My New Desire :- Battery awful!!

Ive had my new HTC desire from 3 UK for a couple days now and although i had read the battery life wasnt great on these things im shocked how bad it is!
For the first couple days the battery was not lasting the day from a full charge in the morning so i decided to try the new leedroid 2.3a on it.
Still no better. The phone does seem smoother with leedroids ROM but from a full charge this morning 8AM to now 2:15PM the battery is already down to 30!! I have not really been messing around with the phone alot, couple of txt and a phone call but thats it.
Any tips on what i can look into to see whats killing my battery so fast?
Had same problem with sense roms untill i swapped to cyanogen mod. Running 6.1 with defrost kernel. Always have above 30% when i put it back on the charger, 15-20 hours. Used alot. Try a aosp rom. Guarantee better battery life.

How much are you actually using the phone? I'd imagine you're on it quite a bit so of course battery will go down quicker
I also assume you didn't make a note of your original ROM version so you can go back to stock with an RUU if you decide you wanna send it back...
battery sucks...get used to it. sorry.
I've had a desire since may and i can count on one hand how many days my phone has lasted till bed time from a full charge in the morning.
some tips for you
3g kills your battery, 2g and sync on will use less battery than 3g and sync off.
get some power widgets to controll your phone, ie 2g/3g, sync, wifi, brightness, gps and use them wisely.
a bright screen on an amoled desire will kill your battery...turn it down unless you cant see it.
+1 for cyanogenmod
That is not true in all cases. My battery lasts more on 3G compared to Edge,not sure why. I experience frequent overheating as well when on Edge. 3G+WIFI Hotspot tend to last more than 2G+Sync.
I've been using auraxtsense for a while now, with browsing the internet, texting, maybe 20 mins of phonecalls my battery would last around 36 hours on a full charge, however i've gotten into the habbit of charging phones when i go to bed anyway.
I've left it for 3 days before doing nothing on it other than getting the occasional text message on some days off from work.

[Q] How did this happen? (RE: battery life)

I'm running CM 7.0.2 with the Tiamat 3.3.5 (No SBC) kernel. Flashed the kernel after booting the ROM after the flash and my battery over the past three charges are as follows:
1st charge: 1 day, 7 hours till 5%
2nd charge: 1 day, 6 hours till 7%
3rd charge: 14 hours till 20%
I don't know what could have caused such a drastic change! Any clues? (Checked partial wake lock and nothing is doing anything unusual and I haven't added any apps anyway.) Furthermore, used my phone about the same all three charges.
Are you complaining about that battery life? One day and seven hours? Did I read that right or am I missing something?

He was wondering why the first and second day yielded over 1 day, and the 3rd day was less than half of that. There are a ton of variables in that situation though, so its hard to say. Maybe a rogue app or bad signal or something like that.

Ohhh, I see. I just noticed that the battery life was better than mine. My first response was to question why someone would complain about that. I use my phone for everything though... all the time. I stopped worrying about battery life and bought three cheap batteries and an external charger, now I'm set.
If you were in a different area with a bad signal, that could definitely account for the drop in battery life. My battery tanks if I don't have a signal at all, especially with 3g on.
Do you have an extended battery or just good battery life?
I have the stock battery. Maybe I just got lucky a few times! I mean, there's times where I've gotten 24 hours on Myn's Warm Z, which is a ROM that, while stunning and fluid, surely does suck a bit more battery up. Of course, most of the time, I got 12-15 hours on Warm Z.
Maybe it was just a fluke?
I had service almost the entire time. It was like 1% time without signal.
I most certainly was not complaining about the first two days! That battery life was amazing and I really didn't even think it was possible. I was really just wondering what happened to cause the extreme drop suddenly.
Hm. I wonder.

[Q] Horrible EVO 4G Battery Life no matter WHAT I do!

I've about had it with my EVO 4G. I can barely use the thing before the battery is down to 30% or lower. When I first unplug it in the morning, I'll browse reddit or XDA for all of 5-10 minutes and my battery will go down to 75% easily. I've tried tons of ROMs (running Energy w/Shooter Anthrax kernel as I heard it got amazing battery life) I've tried resetting the battery stats -- i've tried unplugging and replugging in the phone multiple times when the charge light is green, I've tried just about everything I can find on here dealing with battery issues and to no avail! Listed in my battery stats the only thing that's ever high is my Display usage but even factoring that in should I really only be getting an hour or two of mild internet usage before my battery is completely depleted? I can barely make it through a 6 hour work day (checking texts on breaks, light internet, maybe a 5 minute phone call) without having to recharge it in my car.
I'm open to ANY suggestions short of buying a new battery -- sadly it's not an option at the moment.
Do you keep 4G on? That drains a battery like nothing else if left on. Same with GPS, especially in Sense Roms for some reason.

i recommend using a aosp rom if battery life is a MUST. I would suggest you use Decks aosp rom with CoD tweaks Tiamat 3.7.7 and vipermod and underclock to 500 on smartass governor........all this is what you should do if you choose decks rom
Make sure your 4G is off, but Evo is known for its horrible battery but thats ridiculous. Try a new kernal to adjust to CPU settings. If that doesn't work, you might need a new battery. Evos are know for having their battery fried easily, mine fried and I had to get a new battery. :/
You should definitely make sure your 4g, Gps, Wifi, and blue tooth is off. If that does not work I would strongly suggest you downloading Cyanogenmod 7.1. When you aren't using the phone under clock it and do medium speed when you are using it. I last around 8-9 hours doing this. Hope it helps.
Okay I installed Decks Evo GB rom and the Tiamat 3.3.7 kernel. I followed the guides but couldn't seem to do the undervolting correctly with the apps i was provided...but i'll do some testing and report back!
Can someone point me in the direction of the right app for undervolting and whatnot?

vipermod is used for undervolting http://vipermod.tiamat-dev.com/vipermod-voltage-control/
Also, it could just be that your battery is tired. Is it at all swollen, in the least bit or rock hard? It should feel firm, but give a little.
People tell me all the time, "my battery is not holding a charge", it's not designed to. But, how it releases the charhe, is another story. Obviously, it's also dependant on use. Remember, the phone is only rated at 5 hours talk time. I can't think of a time I've actually tried that, but when I have been caught on the phone for extended periods I've only gotten at most 2 hours of conversation out of a full battery.

my battery doesnt last too bad in my evo. granted not like the old days, but i do get about 12-15 hours on a 1700 mah battery and a powerskin charging case with a built in 1500 mah battery. This is in a poor service area.. constantly switching into and out of roaming. i keep 4g, wifi, mobile network all off and screen brightness at about 25%.. this is with moderate txt, some light game play, occasional turn on 3g to check email and browse web. im expecting better now thzt i am rooted with energy rom and anthrax kernel.

Which ICS rom has given you the best battery life?

So right now I'm on AOKP, and this and every ICS rom I've had bad battery life, I have only gotten 2 hours of screen on time, maybe 2 hours 20 min. I came from Juggernaut when I would easily get 3.5 hours of screen on time, and I even find myself charging my phone a lot more often. So just wondering which rom/kernel has given you guys the best battery life

On GB: Juggernaut/Synergy
On ICS so far: Telus stock v4.0.3/stock kernel
Darkside Telus 4.0.3 build has fantastic battery life for me. I get about 2% battery drain per hour (when the phone is sitting idle) and on a typical day I will still have more than 50 - 60% battery left when I go to bed. That's after the phone has been on for 15 or 16hrs with moderate use.
If I use the phone more heavily I can get over 3 hours of screen on time.
If we're talking ICS rom's, I'd say 'CM9 20120620 Unofficial' gave me great battery life. I used it for almost a week. I had BLN disabled and was very impressed with the battery life. I could make it an entire day with mod/heavy use. I've run several ICS rom's, and by far it beats them all hands down. It might not be on par with our GB rom's yet....but it's getting close. They've now removed BLN support from the kernel because of the battery drain. But I found just disabling it was enough for me.
I'm getting ready to flash nightly 6/27 with bln disabled. I'll see what kind of improvement I get, if any, with it being disabled.

i put on darksideevolution v7 yesterday and after 10 hours i had 65% left. i did about 40 minutes on the phone, texting all day, wifi/data turned off when it wasnt being used (easy to turn on/off with the toggles)
Honestly I haven't had good battery life since I got this phone 2 months ago. I've been tinkering alot, mainly with Darkside and now AOKP with Eugene's kernel on lionheart. My wife's stock t989 gets great battery life, but I can't live in stock. It seems like I can leave my phone unused sometimes, maybe overnight, and the battery life is great (9% used in 10 hours) but as soon as I pick it up, it drops 20%. Must be that big screen. Anyway, I'm trying to get this worked out. I'm getting my preferred rom figured out and then hoping to let the battery settle into it. Always an experiment...

[Q] Battery Life after Blu Kuban

Hey all,
I recently put Blu Kuban on my phone and I'm loving the look and feel, but I'm having REALLY bad battery life. I couldn't get through the day with only a little use. I download the battery calibration app and tried that. Its also been about 4 days since I flashed the new ROM. Anymore suggestions? I bought an extended battery at 3800 mAh and I'm getting less than a day with the new ROM. Before the update I was getting at least a day and a half with MUCH more usage.
So long story short, BAD battery life. Any suggestions? If I cant get this figured out, I'm going to have to go back to stock.
Thanks in advance.

Hi. I've noticed you posted two separate threads relating to RUJELUS' Blu Kuban ROM. I would suggest you ask in his thread if you haven't already due to the fact that he may offer more assistance.
However, there are many different battery solutions. The problem is, if you were previously running Stock Gingerbread, you must get used to the fact that until Kernel source drops, battery life will not be as good on ICS as it is on GB.
To address your ICS battery problems, I suggest you turn here:
http://forum.xda-developers.com/showthread.php?t=1668853
Also, if possible, it would be nice to see your battery stats. Take screenshots and post them up here.
I would definitely post in the thread if xda would let me. I tried because I had that thought originally and because I don't have 10 posts yet it wouldn't let me post in the thread. I will post battery pictures tomorrow but its pretty much saying like 36% android OS, 20% display at one hour of use.
Thanks for the help so far guys. I checked out the first link and changed a few things. Hopefully it helps.
Still rocking Gingerbread ;p
How old is your battery?
How old is your phone?
How much do you have running in the background?
Do you keep WiFi on at all times (so that it might be searching for signals constantly)?
Use the apps listed above to try and get an idea of what could be causing the drain.
Hopefully it will improve so you can fully enjoy the ROM.

My phone was purchased in October. My battery is about 2 weeks old. I don't believe i have anything but gmail sync in the background. However, I'm not used to all apps I used staying open after I use them so I've been kinda bad about closing them. Is there something I can change so this goes back to closing most things after I press the back button. I do not keep WiFi on.
My extended battery got about 18 hours and was at 15%. I slept for 11 hours last night with nothing on. I used facebook for 15 minutes, just responding to a post and scrolling through messages and battery dropped at least 10% if not more. Granted, I was trying to download the update but doing that for 10 minutes dropped my battery over 20%. I'm very concerned.
i get good battery life im using trexcell extended battery and you realling expecting to last a whole day in one charge hell no no way unless you dont use your phone

I essentially didn't use my phone for half the day. I can't expect with a battery double the size to get 12 hours of light use?
are you on the latest build? Im on 1.0.4.1 and my battery is pretty solid, Id say give it a few days. are trying different modems?
I experienced the exact same thing on that rom. It is definitely one of my favorite roms but I would get half the life that I would on the others I tried.
Were you having issues with battery at all before you flashed the Blu Kuban?
I'm running Blazer ICS now and getting almost as good of battery life as I had on Gingerbread.
So here is my screenshot. In next post ill type how long each process was running.

So 3 hours and 46 minutes. Less than 50%.
Android OS CPU total: 20m 36s.
Stay Awake: 1 hr 8m 34s
Screen: 34 minutes 17 seconds (last 10 minutes or so has been trying to get this post up)
Facebook: CPU Total: 10m 25s
Stay Awake: 2m 34s
GPS: 3 seconds (turned off immediately after realizing it did that)
Android System: 7m 10 s. CPU foreground: 8 seconds. Stay Awake: 4m 27s
Cell Standby: Time without signal 4%
I figure thats enough but if not let me know. I just updated to the new version so I guess I'll have to give it another few days, however this was typical of the last version. Please help, I really like Blu Kuban.

1. You're addicted to Facebook lol
2. Your signal seems very low...could be your phone is running up its battery trying to get signal
3. What are your wifi settings? Use one band only and leave sleep mode "always"
4. What is the brightness on your screen? Set it lower and unselect auto adjust
5. Sync can kill your battery, either remove some things from sync (like Facebook) or remove them all and only sync manually

Wow, that is incredible!
You slept 11 hours? I have not gotten that much sleep in years!
In all seriousness, I have recently gone back to Blu Kuban and the battery life will get better after at least two full charge cycles. I am currently at 9 hours and 75% remaining. I am in a low signal area and keep data off and use wifif when available. I do use Juice Defender to automatically turn wifi off when the screen is off, so when I am not using my phone, I can still receive calls and SMS.
My battery life on Blu Kuban is really good... been getting like 25-30 hours for the past couple of days. One thing that you can do to maximize battery life is turn off haptic feedback and also turn off pulse notifications. Pulse keeps your phone from entering Deep Sleep and haptic feedback also uses a lot of unnecessary battery.
I found out what my problem was. My extended battery has gone to ****. I took my extended battery out yesterday and put in my standard battery and it is running better than the extended battery. What is crazy is that I replaced my stock battery because it was running poorly and not getting good life. Therefore my 3600mAh battery is running worse than a BAD 1800mAh battery.
Tips though to improve battery life that I found:
Download CPU Spy
Download GSam Battery Monitor (Previously known as Badass Battery Monitor)
- Use this to see what is using your battery up.
Turn off any data syncing you don't need
Turn down screen brightness to an acceptable level
Make sure you close the facebook app because its a crazy battery drain
Give your battery a few days on a new rom to even out
This is what I can think of right now.
Good Luck all!
