Very high standby battery use

Today i've noticed that my Desire uses avfully alot of power in standby;
since it was dead in the morning (while at ~60% when i went to sleep)
the drain @ standby is around 300mA...
So i figured maybe some app is preventing cpu into going to standby, so i've flashed my 3 days old backup, which was working normally at the time (no power drain) but for some reason the power drain stays the same today when i've flashed it.
I've disabled wifi,bluetooth, even put phone to flight mode, but drain is still high, which makes no sense , since its an old backup which was working fine at the time.
Anyway i have AMOLED Desire with Leedroid 2.3d and countts latest kernel.
Its really wierd why this suddenly started to happen.I just hope it isnt something with the hardware....

I've just tried the latest Oxygen rom and its the same thing... high power drain... ;(;(;(
Its really wierd...different roms and the same issue...

Now i've flashed back a fresh leedroid 2.3d and still no luck.I loose almos 30% battery per hour while phone suppost to be in standby!!
I've tried setcpu profiles and set 128Mhz when screen off, but power drain stays the same.
Could it be somekind of hardware damage, becouse i've tried many different roms and still its the sam thing ?
According to some app that monitors whan is using cpu, it says that system_server occupies all the cpu.But i cant find much about this....
Anyway if someone has an idea, i kinda like more than a 3h battery life a bit cooler phone (its quite warm when in "standby")

I've had this issue as well with CMY build #23 but it seems fine in build #24. Also, how do you check you mA output or what ever?

I have checked this with Battery Monitor Widget while having it run off the battery.
Isnt leedroid based off HTC stock rom ?

You could try flashing another kernel but I'm not sure if that would make a difference since it was running fine several days earlier.

tried flashing bunch of different kernels, same thing.
ill try another radio if it helps

If you open spare parts you can see if your phone enters standby and if its not you can see what app is stopping it.
HTC DESIRE CDMA Cyanogen 7

tried older radio... still power usage doesnt drop below 300 mA.
i really suspect that something is wrong with hardware...
only thing left is to unroot device and install stock rom.

will check...

where in spare parts should i check this ?
cant find anything related to standby...

although it seems that "android system"
is eating most of the processor.

Get Spare Parts > Battery History
Partial Wake usage - You need to check this from spare parts( more info on Partial Wake usage)
If it says "Android System" / Try it with the following changes
* Settings > Date & Time ( uncheck automatic)
* Settings > Wireless & Networks > Mobile Networks ( uncheck - "Enable Always on mobile")
* As usual disable wifi/bluetooth etc., etc.,
If you use notification bar power control or Battery mod , it also consumes extra cpu usage
one more thing, get Watch Dog Lite from android to check if any app misbehave( consume more cpu)

You who have poor battery should test MIUI 1.1.28 really good battery life!!!!
Highly recommended! Lovely ROM also!
Went from one day to three days of battery life

Ill give miui a spin, but its not my battery's fauls since its fine, its the power drain thats the issue.

I've also noticed while putting phone to airplane mode, that in this case "Phone Idle"
uses the most battery.But battery drain is still 300+mA.Which is wierd since this suppost to use least power.

Have you tried deleting battery stats? I was getting abnormally high stand-by battery use after flashing to a different ROM from stock; after charging to 100% and deleting battery stats in recovery it really changed.
Then again this can apparently backfire and make the situation worse according to some :/

Ill try this...maybe it helps ...

I've reseted battery stats and flashed a fresh stock froyo (with htc utillity so im rootless now ) and hell power drain is the same !!!!
Guess it must be something with hardware or something...

My phone state running android

Hy everione ii decided to make a thread about my kaiser android porting state
i currently use sccoters cyanongen mod 6 with sys and data on nand im using his kernle just changed the panel type from 2 to 3 and now i have no more screen issues
The speed is preety good for an 2007 phone
The apps that i mainly use
Advanced task killer - a very helpful program when you have only 30 mb of ram
Astro-the best file manager my opinion
IM+ pro-a messenger ap
Shazam- a music recognition software
Thinkfree Office- a very slow office like app
Tunee Music pro- a music lybrary from where you can download free music
and offcourse xda app
Now i tryed fruity ninja but it runned pretty slow and everyone know the ,,awsome,, touch screen of these devices
Anyway curently i experienced some big issues
The wireles connection is somehow dropping i mean it dosent dissconect but the apps just lose it soethimes
My 1st issue the battery i cant chcarge the phone correctly i and it last only 7 hours
I tryed shuting it down and charge it but it restart itself
I really need to resolve the charging thing because its my prymari phone and i dont have other
I`m searching for faster experience and an working chargin tehnic )
Please excuse my english

Hi Cos:
Patience is all you need with the battery issue. If the kernel was written correctly for the phone, then the battery level will pick up and adjust. Any time I do a fresh install I have to wait for the phone to almost die before charging because battery level is always at 15% after install.
Wait for the phone to be about dead (look at "battery information" under Spare Parts. You will see the battery voltage listed in millivolts (shown as mV). As long as that voltage doesn't drop below 3500mV, you'll be fine. Once it does, charge it from that point on. It "should" pick up on the low and high battery voltages pretty well after this.
High volt reading is around 4150, lowest should be no less than 3500. If the battery never reaches 4150-4200, the battery is bad and should be replaced.

No problem here
My Kaiser "Android powered" last for 2 days - sometimes more.
"atools > Battery Capacity > Advanced Settings > 3200"
A have standard 1350 battery
PS: NAND install and no suden drops in battery level

[Q] Battery issue : software or hardware ?

Hi everybody,
I'm facing with a big issue since a while with my battery life. The battery is draining very very fast without visible reason...
I've tried everything to spot the problem but I now wonder if it is not an hardware problem (died battery).
So how can I know if I have to replace my battery or not ?
Thanx
P.S : sorry for my english

There are lot of recommendations to improve your battery life, have you tried them? Explain more about the problem.

What I've tried :
- Calibrated my battery with all the the existent tutorials but it doesn't shut down at 0% (but not my biggest issue)
- Installed current widget and studied the current log which showed normal values (5mah in sleep) with few higher values
- Installed Better Battery Stats which didn't spot problem neither in ''Process" or "Partial Wakelocks"
My current set up :
- Latest Oxygen rom, with recommended kernel and radio
- Set cpu ==> wake up 245 - 768 (ondemand) / sleep mode : 245-384 (powersave or ondemand)
- Automatic luminosity
- I manually switch off 3G every time I turn off the screen
- Synchro : mail (every hour), facebook (every 4 hours)
In general, my battery last 8 hours even if I don't use it a lot...

Did u try to use a different Rom.
I had the same thing with Oxygen. Just went to ICS and now everything last even longer.
I also got stunning results with a MIUI rom, about 2 days of usage.

Yep, approximately the same results with every roms (aosp, sense and miui)

I would try CM7, anyway how old is your phone? and for how many time you 've been with this trouble?

I already tried cm7
I bought the Desire at his launch so about 2 years ago. I've been with this trouble since 4 month approximately...
I am more and more convinced that this is an hardware problem (my battery may be dead)

See in Battery Stats what exactly consumes . Screen is very hungry , even on automatic , after that comes phone calls , wi-fi , data transfers

Why opening a second thread with the same problem????????

I already checked several times and indeed the screen is very hungry (40 to 70%). Then, comes the wifi, cell standby, android OS, phone idle.
Nothing unusual regarding what I found in this forum...

Server bug

battery life

Ok so ive installed alot of custom roms on my wildfire s and on all of them my battery life sucks. If im on wifi my battery goes down 10 to 15% in like 2 to 3 minuets. Do you guys think its because of the roms or i just need a new battery. Please help.

Type in the call menu : *#*#4636#*#* and go to battery menu.Wrote there all the informations.
Do you full charge your phone ?(about 2-3 hours)
Try to delete the batterystats.bin file via CWM.
If i helped you,click "Thank's" button.Have a nice day

10 - 15 % in 2 minutes? WTF?
Are you sure your battery isn't faulty?
Even in worst conditions my battery never drained that fast.
Anyways here are some tips:
-Charge phone to 100%
Go to CWM and delete battery stats.
- Dial: *#*#4636#*#*
Go to phone information, In preffered network type Select GSM auto PRL.
- Use juice defender or something which would turn off wifi whenever its not being used.
- Make sure all the accounts aren't set to push as it takes a lot of battery.
- End processes by going to Apps-> Running services.
- Don't use heavy widgets on homescreen or launchers.
- Brightness to auto and timeout time must be less.
I could remember just these. But I guess if it's true that your battery is draining that fast most probably your battery is faulty. Get a new one.

sounds like a faulty battery.

Kill/Uninstall Apps
Yeah, I had this problem :/
What I did was
- download a battery saver app, It closes mobile networks when you're not using them.
- Set the screen to a low but visible setting
- Uninstall some of the memory draining apps
- and kill some of the RAM munching apps.
Hope this works :L

ill try some of them

Don't download a battery saver app, it'll just use cpu cycles and battery even more.
Manually turn off mobile data and wifi when you're not using them.
Don't overclock.
Lower your screen brightness.
And ultimate solution, get an extended battery.
-----------
"You can overclock as much as you want, your phone will always seem too slow."

What kind of charger are you using to charge the battery? If the charger's voltage and Amp's out put is higher then what the phone can take it could be over charging your phone and charging your phone way to fast. If your charger is normal then I would invest in a new battery, a o.e.m battery is good.

[XS] Appalling battery life

I'm currently running 4.1.2 stock, rooted. With Locked BL. The battery drain has been absolutely shocking. Help

Download from play store this app: Du Battery Saver&Switch Widget! I have this app since last week and it really works...

People in here are right. Greenify it's more than enough. But also Du Battery Saver can do the trick, what's great about it is that is lowering your CPU frequency when screenlock, so try them out.

Use screen settings as low as possible. Trust me, thats the main cause of fast battery drain.
Use Lux auto brighteness. Its a good app.
Next one , use titanium backup to freeze the app that you are not using. Its always a good to freeze app, so it wont run in the background and u can save RAM.
Use greenify. Thats the best app for hibernating the apps. That way both battery and RAM is saved.
And use DU battery Saver , thats also an awesome app. in which u can set the phone to change your profile on time basis, and lower frequency of cpu when screen is locked so battery is saved.
Hope u got some ways to prevent battery drain to a limit

Those apps are all great, but why have a HD Screen phone when you have to lower the screen brightness to a minimum, that sucks.

It's very simple, at du battery select saver at the bottom and create your own custom mode!

Thank you all for the responses, I will try out all the suggested apps and get back to you all. Thank you!

Keep the brightness around 35%. I find it perfect for indoors. Your screen on time should be atleast between 2:30 to 3 hrs on average.
Use darker wallpapers
And underclock to 1.2ghz or something if you dont use resource hungry apps. Use conservative governor and noop scheduler.

Trinity ROM
Screen brightness at 35%
Stamina mode on
Using greenify
Only 2G networks
Moderate Wi-Fi usage
Default CPU frequencies

Also, don't use battery savers like go battery saver and battery doctor, they only turn down brightness and data networks, alot of them don't have a great effect in battery life. Use apps that freeze/hibernate apps like greenify and snapdragomln battery guru.

so i did realise that you had your screen on alot of the time.... that is generaly 1 reason why , i can watch 8 hours straight of movies on my XS where as on a stock rom about 3 hours , so the XS battery realy depends
list
sometimes the battery will just need to be used normaly just so it can calibrate its self (some weird reason not using my XS for 2 days fixed my battery issues)
i suggest checking if there are any apps that run in the background, just remove them if you dont need them (could prevent your XS from sleeping and also a posible overheat)
I also suggest making sure that your brightness isnt too high, (obviess)
the more you use your XS the shorter the battery lasts day by day, it is nessicary to not use your xs too much as it will take a few days for the life to go back to normal ,(like i said i had a simular issue)

I can see a strange behavior of Mediaserver process. It consumes too much battery. Usually it points to the problem with scanning your media files.
You can use BetterBatteryStats to find out the cause of it.
