Battery life just terrible, need since help plz!!

As title says guys, I don't no why but my battery life is just really bad since I moved from stock 2.1 Rom to custom ROMs :-(
Is it my phone? I can't work pig wot it is. I checked the battery usage #*#*4636*#*#) and it seems the Android system is using A LOT of it. I tried charging with phone off, clearing battery stats, not overcharging, but just can't resolve this issue.
Also, I have sync set to update manually and have mobile internet off always, only on wen needed. Same with WiFi. Screen is on auto and time off screen lock set to 30 seconds
I am using OpenDesire sense Rom
Any help will be really appreciated.
Thanks

I could feel WiFi siginal of 2.2 is much better that stock 2.1,
I suppose that the better performance will bring the fast battery drain,
if your custom ROM support WiFi N mode,
that really makes your battery life short that before.

I have the same problem and same settings as you. I read on other forum that people who updated to official 2.2 have even better battery life.
I cant even squeze 20 hours out of my battery :/

You guys should always post what ROMs you are using...

Opendesire 3.3, its the same with defrost.

i also had really bad battery life on those 2 roms
even doing nothing the phone would just keep dropping
go to official froyo 2.2
neophye roms for me have amazing battery life = 48 hrs..

Agree with cygnet

Is there another non sense rom? I really like stock better...

Check if the phone goes to sleep correctly. Spareparts > battery usage: other usage, since last unplugged.
I had the same problem, until I found out that the phone was not going to sleep. (running and screen on percentages were way off. Almost 100% running and a lot less for screen on.

update to the last radio

I found that after forcing everything to install to SD card my battery life plummeted. There were apps/widgets that should have stayed on the phone. Once I moved these back, battery life was back to normal.
I use Systempanel to see the battery drain graph and could see a pattern to it.

Same issue here, Will try Neophyte tonight
Using this rom http://forum.xda-developers.com/showthread.php?t=741663, and it's fantastic! However batt life on .08 and .20 radio is a shocker. I watched a 1 min trailer on youtube, in and out and I lost 4% battery. Before with OpenDesire I'd be shocked if the battery percentage even twitched slightly.

I use Defrost 1.5a and I just use about 2% every hour when the phone is sleeping, and that's with auto sync and mobile data enabled. (disabled it's 1%/hour)
Always underclock to the lowest mhz when the screen is off using SetCPU and when you do use your phone make sure the brightness isn't too high.
I could make a whole list of tips, but I'm sure you'll find more than enough of those on the net.

I may be dumb but how do you force your phone to go into sleep once screen is turned off ?

(using Cyanogenmod 6)
When your screen is off, your phone should automatically go to sleep. Sometimes widgets or apps keep this from happening (like the music player), making it use battery as if you are constantly working on it.
How I resolved this issue was to find out what app or widget caused this. I ended up starting from a fresh reset, installing first all apps I really use (calendar/message widgets, powerstrip etc.)
I tested by installing an app, rebooting (or sometimes not), check the running time of the phone, turning screen off, and check again in 5 minutes. The phone should go to sleep in about 30 - 40 seconds. I am telling you this, because most apps causing this are widgets/apps running constantly.
However, I found in spareparts also that 'settings' was taking alot of usage time in usage statistics. A simple reboot did the trick from here on. But I am guessing I had installed something which made some app not close properly..
Maybe it is better to have a task manager/killer for these situations.
Running and Screen On percentages should not have too much of a difference if your testing and not using the phone while screen is off (music, bg stuff)

You could try juicedefender, it helps improve battery life by disabling unneeded connections while the phone is not in use

[Q] about battery life on sense roms

Probably not the newest dillema but here goes nothing, since I've read all the posts regarding battery life, almost all comments from custom roms threads about that and so on.
Right now im using MCR r8 w/ addition + a2sd. My apps list running on desire can be found here:
http://www.appbrain.com/user/baadnewz/apps-on-the-phone
Now my problem is that ive tried Pinky Desire, Leedroid, Nextsense, Delite and for the life of me, I barely make it through the day with the battery, like unpluging it @ 8 AM and pluging it @ 11 pm. Same goes for all roms metioned above. Tried with .20 radio and now with the newest version .30.
I must say I do NOT listen music on phone and I don't even use gps. I send 2-3 texts, and max 20 mins of call. I have 1 exchange mail running and 1 gmail account, i have friendstream syncing every 3 hours. I use Wifi and 3g. Im using it on vodafone romania, and since im in the city the gsm signal is good.
I tried using juicedefender, and setcpu with screenoff profile, they seem to make it worst (this is my apreciation, i didnt use any stat program to acctualy verify in % but for me so it seems).
To be honest im sick of hearing ppl "my desire last 4 days with music gps and 10000 mail accounts"
I even followed the battery recalibrate guide posted here on xda .
Anymore tips ?
Thanks, and yes I know this is the n+1 post about battery issues but all ive read the info is one inconclusive, some says they battery lasts 3-4 days on "heavy" usage" some they dont make it through the day (like me)
My desire has 2 mounths old.
For example. Last night arround 1 am i went to sleep and i was having 89% battery, this morning arround 8 i was having 72% left. No wifi on, just 3g data connection with exchange syncing @ 1 hour and gmail app for mail

have u tried non-sense rom?

No, since im a really big fan of sense

I have exactly the same problem as the OP.
I have tried all sense ROMS, it seems the best ROM for me was Opendesire which doesn't use 'sense'.
So far Pays has been rather good, but I don't get more than a day from my phone... I too have tried the calibration setting that was on XDA but to be honest, I'm kinda stuck too as I dont know which ROM to use...

Hi there, had the same problem as you and it didn't matter what rom I tried but still my battery kept draining, til I found out that I had a program that kept monitoring my desire's cpu constantly. Check for program's permissions where it won't let your phone go to sleep. Also check any program that constantly monitors your phone and refreshes every second.

The only app running that monitors anything is advanced task killer

Carlo, do up mean that we can save some battery if we stop that program?
I'm also can't get a full day usage out of my Desire.

The program that were giving me problems were OS info, and magic 8 ball, and quick system info pro, hope that helps

I must say I totally agree with you. Changing ROM does not changes battery usage. It just won't last a day. I charged mine twice every single day. With mixed moderate-heavy usage of mostly internet basis.

Again, I totally agree with you. I couldn't believe with the slightest chance ppl could get 2 full days with heavy usage (4 hours of music, 4 hours of wifi, multiple account sync, facebook, few hours of browsing etc). I think they are just trying to bloat up things. (Eventhough they knew it's impossible) (or maybe they completely turned off their handset everytime they dont use the phone)
I also personally don't think a world class and professional company such as HTC will make highly variable units+battery performance for their products. Such as 3-4 days able HTC with half-day able HTC's.
Some ppl always argue that battery performace improve over time after several weeks of charges and discharges. Actually, they don't! Even if they do, the changes between 'just new' and after several weeks were not more than 10% differences. I got a blackberry 9700 and spare Nokia, and the battery last as long as ever started from second or third charges !

Based on my experience you really don't need task killer constantly running in the background, android OS does a good job of killing programs in itself, and task killer sometimes kills programs that need to be running in the background and the OS then restarts the said program which takes up more battery
Sent from my HTC Desire using XDA App

Right now as I'm typing this I'm at 38% battery running for 1 day 20 hours and counting, by the way I'm using DeLite 1.1 as I really like sense, but as I said, it doesn't matter which rom you use, its the programs that drain your battery

Yah i know what you mean, but I dont use the autokill function, I use to kill some programs i choose too

Also check battery use in the settings, my android system use now is only around 5-7%, when i had the battery drain problem android system was constantly above 50%

Looks just like mine, are you on 3g? mine stays on standby for about 8 hours during work, but heavy use when I get out but mostly on wifi since I don't have an unlimited data package

I used to be a sense freak aswell. I soon learned to love AOSP builds, smoother, faster and much better battery life. Do a nandroid backup and then try OpenDesire, CM6 or Defrost (whichever you prefer) just to test the battery life for a day or two.

Yes last night was on 3g, but i turn on wifi @ work and @ home

Could be the 3g, I would think that with you're usage its normal that it would drain quite fast...
Sent from my HTC Desire using XDA App

It seems you have tried most of the tips from the various battery threads. However did you check your running services?(menu/settings/aplications/running services) I seem to remember for instance the skype services uses more than average battery.
Also, initially my battery life on leedroid wasn't great, untill i complete drained the battery, wiped battery stats and ever since then easily 36 to 40 hours connected to 3G, way more connected to 2G.
Also, check the mV value when your battery is charged, 100% isn't always the same. You can check this with spareparts, included in leedroid. Another thing i just remembered, people seem to recommend the overcharged application to check the mV value. On my phone that application actually seemed to drain the battery much quicker.
last tip for now, if you want to connect to 3G network set your phone to connect ONLY to 3g, NOT automatic 2g/3g.

some personal experience, I have stop using the little green thing, Advanced Task Killer Pro for 3 days. i realized my battery last more than slightly longer.
When i was using ATK, especially after waken from 8 hours sleep 20%-30% gone during idle. now without the ATK, these 3 days after i have waken only 5% gone during idle.

Screens off but sucking the power still

Hay I just left my phone on over night to see what uses the most battery with me doing anything.
The screen used 30% of the battery, what is odd is that everything in the settings is off or set to the lowest it can be set to.
Can you guys help me with how to save more battery from the screen, this is silly that its using so much when it's not doing anything.
What can you think of to help?

Are you unrooted? Do you have a custom ROM? Have you tried taking battery in and out? Or even when these things happened when I was not rooted I found turning airplane mode on and off to work or rebooting the phone as it might of just been a rogue app not allowing the phone to sleep.

hi ,
i would say it is a app,behaving badly ,( badly coded, battery drain? ) that's draining your battery like that ..?
i would suggest try "currentWidget " to check you battery drain ( just remeber to enable the log file, in settings !
my drain, if i leave it overnight,
say about, 9/10 hours, is about 3%/ 4% for this period ( 1mA /3mA a hour )
also try "SystemPanel " to monitor you applications over period of time .
i had same problems as you,
say 15/20% battery drain ,from time to time ,but everytime managed,to id the culprit , with above apps ..!!!
you can find both applications in the market ?
you also don't need, any root for these apps above .
good luck

I'm using LEEDROID v5 I think which shouldn't make a big difference.
Thanks in will download the app and see what they say

regarding the OP, with a lot of the newer kernels the power monitoring stuff is snafu, confirmed by Mad-murdoch on cm, thus the reports of what's using the power are useless, although the overall usage is correct.

50ma battery drain on stock and cm7

Hi wildfire users,
my girlfriend got her wildfire yesterday.
The first thing I've fine, was to root it and check the standby battery drain.
It was between 27 and 50ma in AIRPLANE mode, without sometimes at 120??
My device got 1-2 in airplane and 3-5 without.
Thought it would getting better after flashing cm7, took the rc1...not really.
Any suggestions? Iam an experienced android user, but my options are running out, what else I can do.
What I've done:
Checked drain with current widget,
checked partial wakelocks with spare parts-seems okay.
Uninstalled all custom user apps I had installed.
Read here, that reflashing the radio fixes some issues...didn't tried that yet.
Any other ideas?
What drainages do you've got?
Waiting for your answers.
Edit: perhaps it will help to let it charge it to 100% and check again...maybe let it also discharge one time ^^.¿?
....think i was perhaps a bit over motivated...

Battety drain will be above normal just after flashing a ROM. You need to make a full charge and then go to recovery and wipe the battery status.
Then do few complete charge-discharge cycles. Then it will be definitely better than stock rom. And use CPU settings in smart way. Work on the minimum setting and governor. Also depends on other factors like live wallpapers etc..,

Battery calibration gives accurate reading only, it will not improve the weared out battery.
When shifting between roms, the battery will not give accurate reading because not all roms utilize the battery in the same manner (Rom saves the details in batterystats.bin file). So, what if it gives wrong reading. There might be a possibility that it shows 100% even when not fully charged. So we think battery drains faster, but the fact is we haven't charged it fully. (correct me for any errors).
Sent from my HTC Wildfire using XDA App

Yes showing 100% wrongly must be the only situation where battery calibration be blamed. But 8-10 hrs of charging from deep-down-zero should definitely make it full, right ?
Whats your general time taken for charging in standby mode (WiFi, Mobile Data, Bluetooth Off).
I am experiencing heavy battery drain with WiFi, since I installed Sunabh ROM. (He adds a switch off wifi notification to hide this fault. Cunning.)
Any solutions ? May be re-flash the radio or change the kernel ?

Dude, attack the CID bug.
I resolved my issue without even switching of my phone once, let alone flashing anything.

[Q] Battery draining so fast when using mobile internet

I'm using PureKat ROM for my Desire Z, and recently I've noticed that the battery drains so fast when I'm on career's 3G network (WiFi doesn't have this problem). I suspect on Google Play Services and I've disabled to auto-start, wake up and keep awake the phone and most of it's unnecessary services using this tutorial but it doesn't help. I've attached battery usage statistics after charging (all is normal there as you can see). Also I want to mention that 3G is mostly off (especially when it charges) so battery lasts as long as it is disabled (it can last for several days without 3G I think), and charging is really fast!
Has anyone had this problem?

Just to be on the safe side, check to see if this also happens on a stock ROM. I remember my old G2 did something like this. Can't check it anymore because my son killed it when I left him use it.

Thanks for the suggestion! Which exactly stock ROM version to use? And if I do that, it will disable root and restore to S-ON, right?

I thought that the problem was with battery, but when I replaced and tested it again, it still acts the same :/
Can anyone help me?

I think that is normal because my desire z give me only 3 hours on 3g and about 6.5 hours on WiFi and now using htc one it also have quit same battery timing like that !

I think that I've solved it with SetCPU profiles. Battery life is noticeably better now.
