I recently installed the new Kingx Kernel #10 CFS and noticed it had major battery consumption at idle when the screen is off. I would turn off the sync, at setcpu to powersave at 245. In about an hour my battery dropped 10% with absolutely no usage. I noticed this was a problem with King #10 so I switched to King #9 BFS and have the same issue, even when I underclock all the way to 245. My phone lasts about 8 hours with minimum to no usage. What is going on here?
Your phone is probably not sleeping...some apps are known offenders...system panel or maybe default app manager may give you a clue
are you wiping dalvik-cache and cache before you flash?
Uninstall SetCPU and let your processor try to manage power consumption on its own. SetCPU does NOT help with battery life, contrary to popular belief. Do that and report back.
Yes I am wiping cache and dalvik before each flash. I never had a problem with this before. I will try disabling setcpu and see what happens.
Also I believe the phone is sleeping correctly. When I check the awake times and time it from when I turn the screen off, its usually only ahead by a couple of seconds.
check if you have installed tango, that's known to rape your battery

Yeah, they need to include a jar of KY with that download.
So I un-installed SetCPU and my battery consumption went back to normal. I dont get it. I also switched to Kings BFS #9. I have never had problems with SetCPU consuming battery at idle. In fact I could easily get 24 hours usage when I set my phone in powersave mode when not in use. Now it drains battery even in powersave.
I have a question regarding my battery life. Yesterday night at 10:00 pm i played +/- 40 minutes on games like Angry Birds and used my 3G connection for about 10 minutes. My battery dropped from 100% to 61%. When i didnt use my phone (just idle mode) @ 11:46 pm i wanted to check how much battery i had left today in the morning (10:00 am) ..... it whas completely dead 0% .... i have this phone since august but if i knew the battery life whas so crap i would have picked another device.
Is there a way to improve it ??? since i read in diffrent topics people can use their desire for 2 days without a recharge.
- Not rooted
- Froyo 2.2
The HTC Desire is a smartphone running powerful mobile OS and a lot of additional gadgets like GPS, ...
So comparing battery life is impossible.
You can get a battery life of a mobile phone/week if you use it like a mobile phone: No GPS, no data, no playing games, no surfing, just occasional talking. So the battery life is normal and good, compared to mobile phones.
But normally you use it like a smartphone, thus you use it daily, play some games, ... which results in a battery life of a few hours (navigation) up to two or three days (moderate use), with an average battery life of a day (heavy use).
However, one thing for sure: Something is wrong with your phone.
This dosen't mean something is broken, rather you use an app/setting, which causes the battery drain, so you did something wrong, you're the failure, not the device!
Playing a game drains the battery fast. The display is on, probably max. brightness and the CPU and GPU is working like hell. It also gets warm, so you can feel the increased power consumption.
In sleep mode however, it should consume much less than it did for you. Maybe 2% each hour.
So to find what app you've installed or what app you keep in the background running, install a program like Android System Info and take a look at the task list, CPU load should be around 10% if you wait a few seconds and do nothing.
Take a look at the running services (android settings, applications, ...) and check if you really need all of them or if an app is active which you don't use. Then don't force close it, only idiots do this, rather open the app and deactivate the service (like automatic updating)
Next option: Test the battery life again. Maybe an app crashed and caused the increased power draw and now everything is working fine again and battery life is normal again. Then it's impossible to find a culprit with Android System Info.
Also tell us what settings you've activated: GPS/Wifi/Data/BT/...
This is happening because, some process not letting your device to sleep..!!
All you need to do is type *#*#4636#*#*
and check the battery history ,you'll get to know which process is using your battery, and remove that application.

Brightness is already said to medium, i also turned of those life wallpapers and it still drains like ****. When i look at the battery status it says battery life is good. Maybe a application that is running i dont know, ill try to find it out. So far i have a few apps installed which i rarely use.

Thanks will check it out and see what it does now in idle mode.
Idle mode 01:28 pm starts now, will post results in a few hours.
Edit: It's 02:00 pm here and i already lost 4% battery, its 96% now , i did *#*#4636#*#* and checked battery status and it seems wifi is in full use 99.7%. I will turn this off but what about the 3G connection
Edit2: It's 2:24 pm here and the battery status is 92% now, i reveived +/- 4 emails in that time. I checked the status in battery indicator pro and this is what it says
Android system 37%
Mobile Stand-by 22%
Phone inactive 15%
Wi-Fi 15%
view 11%
nothing else......i am really lost now.
Is my battery damaged/broken ? .... how can i reset/callibrate the battery ? or should i contact the shop where i got this phone from for a new battery ?
don't worry, lots of people are having bad battery lifes, and angry bird drain your battery really quickly, so it is quite normal, especially on AMOLED desires.

Yeah i have AMOLED
PS: After 30 minutes without touching it the battery is still 92%.
you could install setcpu and set profiles to save battry life
Might try that.....but after 1 hour the battery is still 92%.....i guess wifi drained my stuff down all the way as i am pretty sure i turned that thing of last time.
i will do some more tests later....
Edit: After 1 and half hour the battery is still 92%, guess the stock rom isnt that bad .

Its not 5:09 pm here and the battery is now 91% (idle, not touched)....guess wifi what the bad thing on my phone.
Tested the battery last night and must say i am happy with the results
10:00 pm yesterday the battery whas 60%, today i looked back @ 11:24 am and the battery just dropped with 10% (3G is on), i didn't touch the phone since then.
Stock Rom / Froyo 2.2
The battery drain came from wifi
I wrote HTC about the battery and they just sent me a brand new one So now I have 2 batteries and I think I'm happy DD
You can check your battery usage with a widget called "currentwidget" (search for it on this forum)
Usually on SBY with radio ON my phone drains from 3 to 4 Ma and 2ma in plane mode. (sounds good with a 1400mah battery)
In heavy usage, it can go anything from 150 to 500ma (ie: playing game with wifi ON)!!
For nice graphics, try to install "battery snap" too.
From HTC themself:
“To also help with Battery Life you can do these steps exactly:
1) Turn your device ON and Charge the device for 8 hours or more
2) Unplug the device and Turn the phone OFF and charge for 1 hour
3) Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour Your battery life should almost double, we have tested this on our devices and other agents have seen a major difference as well“

A known problem with the new update of the HTC Desire to Android 2.2 Froyo is battery life. How users have experienced the change is highly variable. Several said that battery life has improved, some even talk about a major improvement. The others have had problems that the phone charges from a fully charged battery several times in one day. If you have experienced such problems, there are measures, some simple, others more complicated and time consuming. Below I list things you can try, the lightest at the top.
# 1 Look what it's drawing power. Go to Settings> About phone> Battery> Battery usage or enter * # * # 4636 # * # * on the keypad and look around a bit. Is there anything that seems abnormal, or any program that seems to be the culprit, uninstall simply the application and see if that helps. While you can uninstall applications you believe is in the background and drag the cream from the phone's battery. Some applications may slip into the "Android System" in your battery history.
# 2 Uninstall system control and task killers. Advanced Task Killer and similar programs do more harm than they help. It is unfortunately only to realize this and stop using them. Android is an OS made for having many applications driving on the background. The operating system puts himself applications you do not use the idle to conserve battery power. Different programs that measure your performance on the phone, for example, Task Panel never sets in idle and therefore system resources continuously. If you have such software installed it may be time to consider uninstalling it. More on why the task killers and Android do not go hand in hand in to read this article by Android developer Dianne Hack Born.
# 3 Clean your home screen. It can be a good idea to try if it helps to clean up your Home screens from various widgets.
# 4 Do a soft reset. Discharge the battery completely (not that the phone is turned off), turn off the phone manually, remove the battery and reinsert it, restart your phone and put it on charge. This may have some effect and provide an improved battery life. Such a restoration known as a soft reset and should be tested before you do a master reset (hard reset).
# 5 Do a "hard reset". Have you done all the methods above are still not noticed any major difference? Then it's time to do a master reset of the OS. HTC have said they for some users might went wrong during the update to Froyo causing poor battery life, and when it is easiest to do a reset to get to grips with the problem. Although Android automatically sync contacts in the "cloud" so it might be a good idea to make a backup of your contacts (Contacts> Menu> Import / Export). Note that when you do a hard reset resets the entire phone, including messages, settings, themes, installed applications, etc. These are not the contents of your SD card. There are two methods to restore your phone, do a google search on "hard reset desire," so there are many simple guides. After restoration, the idea not to install any applications you had installed before. Install the programs one at a time and not too many at once.

Team,
I am using unofficial Cyanogenmod 7.2.0-RC1-marvel-KANG, recently upgraded it. I am facing the issue with battery back up.Even I have changed the settings in *#*#4636#*#* after that I kept my phone in idle status for 12hrs my battery status was 25%. I have read in one of the thread that cm7 with get good battery life.but I am not getting .Please help me with suggestions
For the same I have disabled GPS, Dataenabled and Syncroniser.
Everytime my battery reaches full charge I unplug and reboot into recovery. Go to advanced and wipe battery stats. Reboot. This is how you condition your battery. The rom becomes calibrated to know when your battery is fully charged.
Don't use autosync or use background data unless necessary and use dimmest screen brightness possible. Make sure gps is off when not used. I get 18 hr on sense 3.5 and I use my phone mostly music, games and web. Always overclocked to 806 Mhz and 120 min.
If I helped click thanks.
Sent from my HTC MarvelC A510c using XDA
in addition to overclocking, use profiles to underclock at certain times like when screen is off make the clock spped for min and max both at 200mhz, and you'll probably save some battery
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.
i;m on cm 10.1 M3 and my battery running out very fast. On data connection something about 30% in 1h. And its charging very fast full battery in 1h. Can someone help me?

Dirty Flash?
Low signal area?
From what I know 4.22 has about 1 hour less screen on time than 4.12. Then again, I think we all here can drain about 30% battery in a hour, if we wanted to. What exactly are you doing in that 1 hours time.
battery isn't what it used to be.
4.1.2 was much better battery wise
Some solutions
you can try apps like:
greenify which hibernates background apps and some other apps which are hibernated as your phone goes in standby. (Root)
Ds battery saver which will turn off wifi when the phone is on standby.
Cpu sleeper which turns off one core when phone is on standby (Root)
Battery Calibration (Root)
Lux auto brightness which adjust the brightness and is battery efficient
You can under clock or under volt or even change your screens colour settings. (Root)
Hope these apps and tips help
While i acknowledge that most of battery life is determined by the actions of the user and what apps they use, some ROM/Kernel combos just have notoriously crap battery life regardless of how you cut it. I have found that 10.1 and its stock kernel are one of those instances. Hell, even while using a different kernel and great settings i still have been unable to get the same kind of battery as i can with other combos. Personally, EOS is the complete package of customizability and battery life out of the box for me. Perhaps you should give it a shot. CyanogenMod is just far too dirty.

All good except for Battery Calibration. That app, and others that operate on the same premise are 100% snake oil. And end user can do the exact same thing that the app does simply by unplugging their phone from the charger after a full or near-full charge. It in no way, shape, or form touches anything related to battery life or battery charge indication.
