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.
Ok, I have a problem. Something, and I have no idea what, is launching Gallery periodically. About five or six times I've noticed my battery being very low, and when I check the battery stats, Gallery will have used 50% or more of the battery. When I look at the stats, it might show it's been open for 8 hours or longer (I don't remember the exact breakdown of wake time, etc.) and I restarted my phone last night, so it's gone.
Last night, I finally got fed up and disabled the gallery app, but that means I lose the gallery app for those times I actually wanted to use it (versus when it's getting launched by a program, or maybe I inadvertently launch it and then launch something else and Gallery is sitting in the background chewing up battery).
Before disabling it, I tried installing advanced task killer, and I could never get it to kill any apps automatically, which included it not killing Gallery. I tried both safe and aggressive (or whatever the next setting is) and tried setting the kill frequency to screen off and every 30 minutes (or maybe it was an hour) and it never auto-killed any app.
So, any suggestions on what I can do to re-enable Gallery, but not have it periodically sitting in the background, burning battery like crazy?
Hello,
I have a very annoying issue with my battery percentage. Typical scenario:
I unplug my phone at 100% after loading it overnight and perform some basic tasks, like for example reading news with Flipboard for a couple of minutes. My percentage already goes down to about 75% to 82% in about 10 minutes. Then I don't use it intensively, only to check the time or messages, so the percentage stays at almost the same amount for hours. When gaming, or performing other more intensive tasks, my percentage almost drops 1 to 2 percent/minute. I get "battery low" warnings at 14% and 4% and then it goes down all the way to 1%. Now I can just continue using my phone like before, for example for gaming, web browsing, for something between 40 minutes and 3 hours.
The issue is obvious: my battery percentage is not calibrated correctly. This has been occuring since more than half a year now. I had many different roms over the years, I can't blame it on one particular one.
Now, I read about a lot of ways to calibrate your phone, so the percentage is accurate again. I have tried a lot one of them. None had any effect. I tried the following:
- wiping battery stats (multiple times)
- completely unloading my phone (restarting it multiple times, boot into bootloader and waited until it just turned off by itself and won't turn on again) and then reloading it (via charger) without interruptions (everything multiple times)
- using the app "Battery Calibration" (deleting batterystats.bin)
- using the app "Battery Monitor Widget" (waited until it shows 0 mAh, then wiping battery stats
- some battery saver app
I also switched batteries with a phone that was purchased at almost the same date as mine (09/2011) and has not been modded in any way. My phone currently runs Jellytime 4.2 R11. I updated it this week, and also wiped battery stats during the installation process at 100% charge.
Any suggestions? Any help is appreciated! Thank you in advance

Easy!
Get a new QUALITY battery.
But maybe that was to obvious for others to respond.
Hello everyone,
Would like to raise a matter about the battery life.
I have updated tostock 4.2.2 recently, I have noticed recently that the battery life is being awkward the least. The device can hold up to 4 days ideal but when I start using it the battery percentage dives rapidely it can go down in 20% if the screen is on for 10 minutes. Did anyone experience this and know how to go around it? Im really troubled as it wasnt like this in 4.1.2 it could hold up to 5 hours of screen now it can barely keep with 2-3 hours!

My charge and battery drain thread is here somewhere...
You can look in settings, battery... let us know what is tops on the list.
Also look at settings, data... let us know what is tops as well.
Note: Most of the time the trouble is with google music player, this years update sux with 4.2.2. If you have 4.1.1 it is no problem.
4.2.2 also does not like media files with odd names and characters. I had to rename all my music files to 2 digit numbers, for the media to stop indexing. Folders don't seem to be the issue, just the files. I get 3% per 12 hours discharge with wifi on while sleeping disconnected from charger, and about 10% per hour under a mix use. Thus able to have 8 hours before charging. I can possibly get a week out of the tablet having sync off, power saver enabled, and Wifi off when disconnected from battery in sleep.

use power saving mode, and download Advanced task killer. Kill all apps running in the background whenever u are done or not using the tablet. and clear your "Recent applications". that should increase the battery life significantly
Same here on videos

Hi guys,
I will search your thread cause I have this huge battery drain problem too.
I'm on 4.2.2 for long now but for 1 or 2 months now, my battery drains very rapidly when I'm watching movies or series ... I can use the samsung player or MX player it's just the same ...
When I'm 100%, i loose more than 10 % in 15 minutes of watching ... in fact my train travel in the morning is 30 minutes, and If i'm watching a movie, during the trip I loose nearly 30 % !!!
The thing is when I'm playing games or do something else, there is no such drain ... and as you I get only approx 3% or 4% per 12 hours discharge with wifi on while sleeping ...
This drives me crazy ...
At 56% at 3:00 pm today (I'm french), since a discharge at 6:00 am, my batteries info from parameters are :
Screen : 39 %
Network / Radio function : 33% (what is this ?)
MX player : 16 %
Sleep mode : 3 %
And the rest is under 2 or 3 % ...
For example, I watch a movie for only 30minutes today and played Zombie Tsunami for approx 20 minutes wich only drains 2% on the battery monitor ...

I wonder if your using data connection instead of Wifi...Data would draw more power when used, that is probably why you see Network/Radio about as high as screen. I have MX player pro as well so it is not an issue with MX player.
When I watch Netflix I get about 12% an hour drain with Miracast activated. As for playing video files on SD, it can be a lot lower to a lot higher depending on size and bit rate. Remember media playback has a number of things going on, speaker / earphones, video quality, and screen brightness will draw power at higher levels. I suggest doing a test with BBC iplayer for streaming when at home since your in France. Watch about 30 minutes with power saver enabled. You should get about 5% drain at most for the 30 minute test. If you are doing that, I would think the Data connection would be your primary issue with power drain. A way you can boost battery while watching video when traveling, you can purchase an external rechargeable battery. Both Data and GPS will suck the power right out of your device much faster than WIFI and there are a few battery calibration apps that use GPS to quick discharge for faster calibration.
Hope this helps in understanding.
I've got a similar issue.
I've seen a change recently, because the battery lasts much shorter now than only a few weeks ago. I suspect it could have to do with having run the battery too low (below 20%) a couple of times, specially with my kid playing games or watching Youtube on it. 49% of consumption is the screen, 27% is Android OS, Skype 11%. I haven't installed any new apps in that tim, although I updated Skype to a well functioning version (4.6.0.42007), but with it consuming 11% of total energy, I doubt that being the culprit. I haven't change the energy conservation setting (it's turned off), so it's not that either. On the other hand I turned on Playstore apps updating recently, and that might have something to do with it.
Today the Note even went dead, I didn't notice any battery alert. Is there a way to turn a SOUND on for this. Can't seem to find it. However, the Samsung UI keeps making little ringing noises with every received mail, right up to the device shutting off (sound on message alert is turned off). Any way to turn that off?

Ah, wow! I always have my screen much higher than any app with battery consumption. I use Dolphin browser for Youtube video while browsing with flash enabled and flash.apk installed as well. I prefer the youtube app for links to youtube from emails.
As for sound, it depends on the app that sends notifications. I just block the device most of the time. Though google has options to use default notifications sometimes it can get confused when you set your devices notifications to silent. Then you must change googles notification to silent as well. I think you do that in language and input in one of the google settings for TTS or Voice. It is really a pain but then again that is why I just block and leave things be. Block is in the Notification panel. you can open the complete switch panel by choosing the squares in the upper right.
When your device hit 100%, unplug your device, turn it off and put it into the power socket. Does it say the charge is 100% or does it take another half an hour before it say 100%?
If that's the case you have a battery calibration problem. The software thinks it's fully charged when the battery is only half charged.

I am sorry to say this... but I have had my own issues with power, and that is why I made a thread about such issues.
What you describe is almost what all OEM Note 8.0 devices do. It will show charging again once you have reconnected power after charging.
It has nothing to do with calibration needed to the battery. I have done this many times with Stock and Civato's ROM. If you do not want the issue with Touchwiz DVFS, download an app to disable it. Then you will not see that sort of issue any more. I do not recommend using tools of any sort to circumvent normal operation, but many have disabled DVFS without ill effects so they have a more accurate view of charge capacity.
Nobody here, including me can tell you what is going on directly with your battery without seeing critical information. If anything post the top battery eaters before you charge. This way we can see what is happening. For the most part media seems to be the issue. As google music player will run in background as Media Server no matter how many times you reboot it will try to re index media files over and over. I froze my Google Music player so the issue is non-existent
Another issue is USB charging cables. Samsung cables are not that good. I moved on to Sony / Nokia cables as they are superior cables and a wee longer to boot.

Thank you for the reply. Regarding sound, I thought it was Samsung's @mail inbox app, but it was Microsoft's Exchange. So that is now on silent. Didn't have any effect (!). Under Settings --> Personal --> Google, sound is also set to silent (!!).
Under Language I found Language, Keyboard, Speech and Mouse pointer, and sound for key press could be disabled (it already was).
The Unit's system sounds for ringing and messages have been on silent the whole time (!!!). Still not getting rid of it.
The low energy alert, I don't know whether that is Google or Samsung's Touchwiz. I have sound (I would like to get an auditory warning)? If so, where would that be? It seems I've been through all the settings, but since I haven't been able to turn off the sound alert for incoming mail, or turn off the auditory alarm for low energy, there probably are other settings I've missed.
Come to think of it, this subject would probably would go better under a different thread.
Thank you for your assistance.

Just search on google play for DVFS... you will need to be rooted.... I like saferoot.zip, and to install xposed framework. Most gamers prefer to disable, but it does wonders for true battery reading and charging.
