My battery life has been great with the current set-up, but in the past 3 hours something screwy happened. I basically went to a function and I turned off BT, Wi-Fi, Mobile Data and GPS. Only thing on was the cellular network and I swear I didn't use it for more than 5 minutes. The battery was at 98% before leaving, now in those 3 hours it came down to 50%. What the crap? The only thing I did was to play Super KO Boxing 2 before leaving for about 5 minutes(It still shows its battery usage as 20% but no option to force close, so I am presuming it isn't running). I did open Maps and HTC Locations(Sense 2.0) for 2 minutes but I closed it because I didn't need it anymore, I also disabled GPS right after that. Now after all of this(game and gps stuff) I had 98% battery. Yet 48% of my battery went into thin air just like that, my battery use is Display: ~40%, SKOB : ~20%, Voice calls: ~15%(About 3 minutes), Cell standby ~2%, Wi-Fi ~4-5% or something like that. These are from memory since I turned it off and kept it for charging.
Any ideas what screwed things up?
Edit: Just noticed you are already familiar with the battery %age lcations.
From what you describe, it sounds as though there were some apps running in the background, slowly om nom nom'ing your battery. I daresay there are a few apps on the Android Market and elsewhere that can tell you what services are running at any given time, so you could get one of those.
If you're after ensuring maximum battery life, however, your best bet is to shut down the Desire, then fire it up again. That way, you can be sure there are no background services to drain charge. Couple that with lowering the screen brightness and display idle timeout (not to mention upgrading to Android 2.2), you should be able to go at least a couple of days on standby.
Sounds like one of your apps is keeping your device awake. I'd suggest getting app monitor like SystemPanel and run the monitoring for a few hours to see which app is consuming the battery.
And get WatchDog. It will notify you if there's any app that use the CPU more than 20%. You can set the percentage yourself btw.
All right, I'll be formatting the phone and flashing the RCMixHD v8 ROM(Was using v7) and then see what happens. i can bet my life that it was either HTC Locations or Google Maps screwing things up.
my battery drains like a bugatti veyron doing 252mph constantly
so what would you advise . is the kernal i have now the best or should i change .. i dont want to reall lose much performance on what i have now but would like the battery to maybe improve if possible ...
from full charge taking plug out searching market for 2 mins the battery drains 5-8% in matter of mins
and i have only had the phone a week
With that kind of drains the problems the kernel won't change that much. There is probably a app that causes the battery drain so looking in to that will have more effect. Also the brightness/screen on is the biggest drain and kernel won't do much about that.
You said that you have the phone a week, the battery needs some time to reach it's full potential and you probably use the phone a lot because it's new. So use the phone normally for another week, after that week let the phone drain until it shuts itself off, leaf it off and charge it till it's full. (there is a different calibration method but this always worked for me)
What do you have now? Stock or rooted?

First of all, I would assume that you don't use the phone non-stop (it would be justified to lose power in a few hours if you're on it non-stop).
I recently had issues with power consumption as well. What I did was:
1) check the built in battery monitor: menu-settings-about phone-battery-battery use. The bad thing about this monitor is that it does not differentiate well the apps consuming power, but you can still see if there's something wrong, as the most consumption should come normally from the screen and voice calls. For me, the most consumption was made by com.htc.bg, which, if I let the monitor on for a few seconds, would transform in the calendar app. Weird stuff. I unchecked the calednar auto sync from menu-settings-accounts and sync. It may have slowed the power loss down, but not significantly. I noticed a significant loss of battery by WiFi. I realized, I needed more information so:
2) I installed an app called 'Power Tutor'. What it does is, it calculates which apps consumes power, and it shows you in percentages. After install, you need to start the 'power profiler'. It will appear in your notification bar. If you let it run, after a few hours, you can see in "view application power usage" who is using power. That's how I discovered that my winamp app was really off the charts using power like crazy. So I went in the winamp settings, and I unchecked some options that could have determined this power consumption, like wireless sync, automatic mount as USB drive, etc. There was actually an option that was overriding the wifi power management, stating that the wifi does not stop after 180 seconds of standby. Basically, if you have wifi on, and you stop using the phone for 3 minutes, the phone automatically turns off the wifi. This was not happening any more, due to winamp. So I unchecked all those options, and voila. It worked, I have now normal battery life.
Good luck!
be aware of a couple of things
1. battery drain for the 1st few weeks are high because of a couple of factors, the battery "learns" and gets conditioned over a period of time (doesnt use the old 16hr charge process). its a new device for you so its a novelty, you probably mess about with it with the screen on more than you think.
2. there is a configuration within HTC's builds and in the memory chip of the battery to stop over charging. the device will charge to 100 and then slowly deplete to 90% while still saying full on the phone. as soon as you disconnect it recalibrates to the correct value which is anywhere between 90% and 100% depending at which part of the cycle you catch it
Some other tips to increase battery life, from a friend of mine in the Romanian forum:
1) use the app watchdog, it will warn you when an app is using too much of the processor and will ask you if you want to close it.
2) juice defender with the paid add-on 'ultimate juice' - with the correct settings... it's amazing.
3) Dial *#*#4636#*#* - phone information-network type: select gsm auto prl. The phone will stay on 3G when it has good signal, and switch to 2G when it doesnt, saving battery
4) Change the wallpaper to a static one, not a live one.
5) Go to menu-settings-accounts and sync and increase sync intervals for weather, news, or even set them to sync manually when you choose.
i will try and answer everything at once ..
ok my screen is on 13% brightness
i hardly ever use my phone , the only real use was to root , s-off, put ROM ETC ON
I reply to about 50 texts ish per day and search the market for literally 1-2 mins to see what new apps are in
i dont play games or anything
the thing the battery uses most is the screen and as i say i have it on monochrome theme with 13% brightness, there is nothing synced , i check automatically for email etc .. actually beautiful widgets is set to auto update every 4 hours
i never use wifi as i have a 3gb download/data usage, i dont use gps ...well i do but i have had no need to .. thats about all i can tell ya
rastaman the pt2 is a bit weird it should stay at 100 if just taken out of charge
I calibrated the battery and that made no difference.

My battery is draining like CRAZY and i cant seem to find out what the issue is. Ive tried calibration several times and using a task manager that turns off running apps every few seconds(which seemed to make it worse) and that didn't help. Auto updates are turned off and fbook is only set to update every hour and brightness is set to minimum yet my battery only seem to last 8hrs. please help. i would really like to pinpoint what the issue is.
Oh...im running ERA Legendary 2.1, CPU speed and voltages are stock
That screenshot is worthless. It doesn't show anything useful. Percentages are meaningless. Get Betterbatterystats to see what is running as far as processes and partial wakes. Get CPUspy. To make sure your phone is going into deep sleep. Get Memory Booster Lite to see what is using your battery and get rid of the auto task killer. That will kill your battery fast.

i only posted the screen shot to show the time vs percentage. i already got rid of the task killer and here is a screenshot from better battery stats. idk how to stop the processes though...
Again the percentages mean nothing. In Gingerbread everything goes through Android system so it will always be highest. If you use your phone only an hour or two a day then it will drop to around 60% with cell standby getting higher. They will always add up to 100% whether on a minute or 10 hours.
You didn't post the partial wake locks screen. Also did you check CPUspy for deep sleep? Did you uninstall the autokiller? You can go into settings>applications>running services and stop applications that shouldn't be running like Facebook or music and video players, etc. Sometimes it's best to get an app like Bloat freezer and freeze apps that keep reloading if you don't use them often.

Another question and maybe the most important...what is your screen on time? I didn't see it in the screen shots. I think Max screen on Time I have gotten is right around 4hours. All the battery tweaks in the world wont help, if your screen is on a lot. Also...make sure to freeze drm, sns and system updates. Use randomlking's zip file.
If none of that works...wash, rinse, repeat. Wipe clean and reflash, rom and kernel.

As I'm sure you know, everyone's battery drainage is widely independent. However; I'm on "stock" Legendary 2.1 and recently with the updated Samurai kernel as well and run Juice Defender Ultimate. I've got some advance settings set but over the past 3-4 days, I average about 20 to 22 hours on a single charge.
My usage in an average day is: about 20-30 texts, about 10 minutes of phone calls, 10-12 emails in and out, 10 minutes of web, whatever app updates there may be and maybe about 15-30 minutes of light to medium use games.
If JDU is something you might want to look into, I would be more than willing to post my setup to get you started. <--For some reason, people are real stingy with their JDU settings.
This kinda thing just happens sometimes, and usually clears up on it's own. Especially common after flashing new software.

Hey guys ive done a similar thread on this a while back but this is a bit different now the issue here is when my phone from 100% all the way to 90 % battery is awesome like so damn good. but when it hits 89% it starts draining quite quick the main drainage is when i put the phone in sleep mode it drains. like i had my phone at 85 % left it for exactly 5 minutes and it dropped to 84%. Ive tried every rom/ kernel out there..nothing has helped or changed. I took it to the warranty they said its a software problem and that didnt fix anything. i have BBS and Kernel wakelock since boot is "wlan_rx_wake" maxing out at 2.6 % the others are just power manager service , etc. Partial wakelock since boot is AudioOut_2 stricking at a 17.8% max. And all the others are NetworkLocationLocator. Currently on Pheonix Rom (Debloated ALOT!!,awesome rom) and Note2core since Pearseus gave me lag issues.
Most battery issues are caused by:
1. antenna transmitting
2. screen time
3. processor load
Troubleshooting should start from the simplest things (Before you replace a motherboard/power-supply, make sure the computer is plugged into the socket, etc). Look at apps that use the network (Google Now, Google Local, Google Maps, Google Mail, Google Calendar, Google Contacts, Google Photos, Picasa, Instant Upload, Exchange ActiveSync, Samsung Backup, Weather Widget, Weather & News and whatever app you decide to install, ie: Facebook, Twitter, Reddit, Viber, Skype, WhatsApp, etc) and make sure you disable or at least change the app's setting to update less frequently.
Make sure you use automatic brightness and feel free to lower the bar around 50% when full screen brightness is not really required.
Make sure you don't have some app constantly running in the background (You can see this from the Battery menu, the phone shouldn't be 'Awake' most of the time when the screen is off).
I manage to get ~15-20 hours out of one charge, with 4-6 screen hours and all of the apps I mentioned above (with proper sync settings, of course).
Thats cool but i really wanna know why from 100 to 90 battery is awesome but then it start sucking up
Do I have wake locks problems? =(
no those look fine.
a wake lock issue will show around 90% of uptime as awake.
your looking around 11%.
The reason its ace from 100 to 90 percent is that to hit 100% you have to over volt a lithium based battery. this is why most chargers switch to trickle around 90%.
so it confuses the battery monitor as its in a way (as the battery level indicator uses voltage to indicate charge) more than 100%
the battery is a 3.8v battery, but between 90 and 100 percent it is at around 4.6v and dropping so until it hits below 3.8v (100%) it drops very slowly.
Now that i turned off Google Now and ticked off all 3 settings under GPS, I rarely lose a percentage when the screen is off. [I lose 1% overnight] With that said, I feel the total opposite. I feel like phone gets stronger as the percentage goes down. Try doing what I did and let us know what happens.
But why does mine drain so quick..people get like 20 minutes of on screen time per 1 % i get like 3 minutes if im lucky..

Lost 10% overnight..,i keep most of my stuff really off but it still drains..
bluetooth off
nfc off
GPS off
My google now is on however i dont use it that much..does that really effect your battery ?
Yeah Aus, try turning Google Now off. I personally think it's extremely overated. It keeps track of your location so it will "try" to use gps even if it's turned off. I think just by the program waking the device"trying" to use the gps is wasting precious battery. Let me know how that goes.
ps - obviously I dont have bt and nfc on at all times because I have no use for them myself. but my wifi and 3 emails are constantly on and syncing 24/7
ps 2- I used to lose 10% overnight just like you but I had Google Now and all 3 GPS settings ticked on.
I'm surprised no one has mentioned it yet:
It's a battery gauge. It doesn't actually show 100% of the time the correct %. It could be not calibrated correctly (shouldn't need to, either). I actually spend a lot of time from 100-80%. Then it drops rather quickly! I hardly ever spend any time below 60%, so I'm sure it's just my battery reporting what it THINKS is the correct battery life %.
After I've noticed my battery can't last for more than 3 hours, I decided to upgrade from ARHD 18.1 to ARHD 19.2 and remove Sense. Phone is faster and it seemed like the battery was doing better, but then it started again with all the sudden decreases: it goes from 35% right down to 25% all of a sudden and stuff like that.
I drained the battery and the phone was shut down and I let it charge all night, when I unplugged it in the morning it went down to 99% right away and then didn't touch it for 29 minutes, that's when I turned on the screen and saw it went down to 90% without even touching it!!! I checked what took so much battery and it showed Facebook with 50%, and I haven't even opened Facebook today. Moreover, Facebook wasn't even opened in Task Manager so how come it drains battery?
Thank you.

It drains because its set to sync your contacts and you feed as well as send notifications for things such as wall posts and messages all of which it needs to check for.
On the drop when unplugged that's normal, the phone charges to 100%, it will still show 100% but it lets it drop to 95% then charges back up this stops the battery from being overcharged.

Ok that's good to know, but 10% within 29 minutes of being idle? That's way too much! How do I prevent it from syncing and such?
Open the app and go to settings. Turn off syncing in there.
Edit : I also turned off autosync in the settings - sync menu of the phone

It doesn't work; I turned off autosync for all apps, turned off any notifications whatsoever on Facebook, and it still drains my battery when idle.
Have you tried using greenify to hibernate it?

Come again? You just spoke Chinese man.
Maybe a good alternative to try out. Uninstall the facebook app and use the mobile site for a while !
Have you checked betterbatterystats to see if something else is draining your battery? I used to use the Facebook app and it drained some battery, but nowhere as rampant as you mentioned.
To be fair though I've been using the Facebook No locations apk in the android themes and apps section, hated how it would turn my GPS on every time I opened it.
I still got notifications if I turned off all syncing and location reporting in the app etc. Lastly, you could try SLK notifications for Facebook.
A simple app that hardly drains any battery life (well on my s3 is used about 2% over a 24 usage cycle). All it does is notify you when you have a notification. You can set it to open in the Facebook app (for example if you greenified it) or you can set it to take you to the Facebook webpage or an alternative Facebook app.

I've uninstalled Facebook when it was 89% and it took about an hour to go down to 85% idle and when I installed it again every five minutes I turned on the screen and it was one percent less till it got down to 71% and now I uninstalled again and it lasts more. It's definitely the Facebook that drains my battery.
Edit: ok wait, no.. I've used it for like 40 seconds and it was 71% and now it's gone down to 66% right away, what the hell is wrong with this?! I ****ing hate this phone!
Why hate the phone? It's the Facebook app you should hate As suggested by chirag, use the app Greenify. It hibernates the apps that you choose, that means it stops it from running in the background and consuming data.

facebook also drains battery on my HTC One.
uninstalled it and the battery improved by miles. it also charged faster.
yeah facebook always runs in the background...if you need to stay connected to chat use ebuddy which is more battery effiecient
best thing now is to greenify it.its greenified in my phone (get greenify from play store)
also...check your mA with battery monitor widget while its in sleep it should not exceed -50 mA while the phone is in sleep with all autosynce and wifi off

i think the facebook app always runs and connects to internet and keeping something on always awake , maybe the radio.
something is wrong with the facebook official app, even though after disabling notifications, they still come through
Also the Facebook Messenger causes a ****load of wakeups...same with Facebook app. Definitely a huge battery drainer! Tried out the messenger for 2 days...unplugged the phone this morning. After 45 minutes i checked battery life by using better battery stats and the messenger had alreday caused 27 wakeups without even using it!!
