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

Now using cord Droid this is much better on the battery.

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..,

How does calibration the battery prevent from it from draining faster ?.
Suggest some thing that makes sense.

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.
Running for more than 2 days now. \m/

[Q] On battery time not resetting

Hi.
Just flashed my Desire to LeeDroid 3.0.8.2
In Settings > About Phone > Battery > Battery Use , shouldnt it say charging while the phone is charging? I remember it used to be like that in 2.2. And I've been charging my phone but at the top where the graph is, says 13h 41m on battery.
I think it shuold be reset after I unplug or finished charging. At the bottom also displays the list of apps that have been using the battery.
I've reboot the phone, took off the battery. It just doesnt reset!
Is anyone experiencing the same problem?

addition :
when I press the graph at the top of the screen in Battery Use, it shows a graph.
At the top , it says , 13h 42m 36s on battery , at the bottom of the graph it says 17h 33m 59s.
If I remember clearly, 17hours ago was the time that I've successfully flashed to LeeDroid. Meaning ,it did not reset ever since!
Someone please help or comment.

update :
in recovery, wiping out battery stats reset it. However, it is still not functioning properly.
here's what ive noticed.
1. when I plug in the charger, the stats freezes regardless if I press refresh.
2. after unplugging, and did a pressed menu button > refresh in "Battery Use" , it updates,but resumes the time on battery.
Any help? Has it got anything to do with S-off? I did not do it. :|

Yes I have!
Update : I installed Cyanogenmod too, same thing. Now doing S-Off, will update this thread soon!

Update :
S-off, but still no luck. I dont know whats going on. I even cleared battery stats in recovery. That will reset the numbers in Battery Use.
Please let me know , when phone is charging, under Battery Use , does it say charging? or anything? And after unplugging the charger,will it say time since unplugged? Mine just continues the timer "xm xs on battery"

update :
Ive managed to get S-OFF, ive cleared everything, isntalled different roms(cyanogen)
now back to LeeDroid...
still the same,
I GIVE UP..

Massive battery drain

Recently I had a big problem with my Google Play Store and couldn't download anything or play videos in the youtube app.In desperation to find a fix I relashed my ROM with Odin,did a factory reset before clearing the dalvik cache which seemed to fix it.Because of this I had to re-root and uninstall lots of bloat and set up the V6 script.My phone is running almost perfect now except since that ordeal my battery life isnt what it used to be.It drains terribly even on moderate use.Before all the problems,I had de-bloated and was easily getting over 24hrs on light-moderate usage.Now I'm lucky to get 14hrs and can drain the whole thing in under 5hrs on heavy usage.I check the battery usage stats and the closest thing to the display is Android system.Could it be the ROM posted on this forum is more juice hungry than what I had before,even though its the exact same FW(2.3.6 XEU XXLA2)?Its the only reason I can think of since everything else is in order.Any ideas guys?

try to search Battery Calibration

Hi got this tip from the galaxy ace forum "barebone ics sunday". If it helps you can try it; I've tried it and somehow managed to get a bit more juice. On moderate - heavy usage (talktime > 1.5hrs, > 25sms, email polling every 3 hours, 15mins playing PES + vid clip 5-10mins, + some calculator work) I was able to get my phone to stay alive for 15-16hrs..maybe 'cos got rid some bloatware may have somehow extended standby time..just give it a shot..it may help a bit..

Yes I've tried it on my Galaxy Ace and applied the same set of procedures on my W.
Yes, positive feedback I'd say, although the difference is very subtle/small.
Maybe others can give it a try and report if they feel the difference.
On the ACE it was remarkable maybe because the ROM was stripped down to the bare-bone i.e. No calculator, No Calendar, No Gallery, etc.

Hi all I have phone with battery problem. I tried to turn S-ON or turn off, tried to rewrite soft also I bought new battery and when I put battery to my phone it shows 30% but when i put same battery to my friend wildfire it shows 100%. Also when I leave my phone to charge threw the night( about 8-9 hours) it charge to 71% and stopped, it is not showing more then 71% also it drains very fast but when it shows that is 3% left it last longer than other time from 71% to 3%.

It is for motorola, will it gonna work on htc ? Also when I charge my battery for 4 hours or for 48 ( turned off the phone I mean) it still lightning red led not green. Always it charged till 71 %

Worked for me on my WF using CM 7!

Okay I will try this, nut what about app Battery Calibration, does it work ?

Don't use an app because it is software based, but the guide i've posted is hardware based!

Ok thanks for the information !

1. While in Android, charge up to 100% and leave the phone plugged in.
it dosen't charge up to 100% to use this method

In this case 100% are the maximum you can reach. You can check the exact battery status in system settings!

1. Sorry, haven't thought about that. Yes, it has to be rooted.
2. If your phone is rooted you can find it with root explorer.
3. Yes, for rooting your phone needs to be S-OFF
Maybe you can use that one - found it in another topic:
1. Power on your phone then connect to your Charger and Fully charge until the LED changes Green.
2. Disconnect your phone from the charger and then power off.
3. Reconnect your phone to your charger with the power off and wait for the green LED.
4. Disconnect the phone from the charger and power it on.
5. Once the phone has fully booted / ready to use ... power off again.
6. With the power off connect the phone to the charger and wait for the green LED.
7. Disconnect from the Charger then power on and use normally.
Needs no root, but I haven't tried that yet. Most of the users said that it worked, but keep in mind that battery calibration can always damage your battery.

My battery never charge up to 100% last time i saw green light from fulfully charged phone was last year. I can charge it for 48 hours turned of it still wont be green

Which status is shown in phone->status->battery status?
