A positive battery story....

I let my phone discharge fully till it turned itself off!
Charged it for 4 or 5 hours.
Now I used it to make 3 short calls (5mins each) and send 10 or so texts, and surf for about 5 minutes, use google sjy mpas for 5minutes, showcase some video to some friends 2mins, general messing 10mins altogether.
Phone is up 40hours now (since charge) and still at 80%. I am very impressed.
I put it to airplane mode between 12am and 7am though as I don't like to be woken by drunk friends texts at 2am etc. (it happens sometimes).
I think those of us (me included) who slated the battery life originally didn't relaise we were using the phone non-stop pretty much for the entire day, trying out all the features on it. I doubt the first week of use will be "typical use" for ANY user
Happy Days

My battery on day one seems fine, 12.5 hours running so far, screen at 100%, everything on automatic syncing (and I mean everything, Weather, Twitter, FB, Gmail etc), continuous WiFi connection throughout, plenty of "first day" playing around and still sitting at something like 20%. With a few more charges and more typical use will last a day just fine, which is all I ask, since I always charge my phones overnight...

When i got my phone i let it run out as it had half power, i overcharged it a few hours then let it die, then i do the same again but not overcharge it and let it die. Now i charge it when i need to but i seem to be getting 3 days worth with usage out of it and i use gps, web and have things on auto. Seems to be much better than when i first had it as the battery didnt even last a day but now its past 2 days.
I assume with newer firmwares etc this will improve

My battery life seems to get worse. I charged it fully ... it has been on for 6 hours and I have put 3g on for a while (1hour max and i barely have used it) and my battery is already 60% ... is that poor?? This is my second phone as well!!!

I thought a full charge only required 3 hours..?

Anyone having surprisingly short battery life go into the phone keypad and dial in *#*#4636#*#*, when you key in that last * you will be taken to a testing menu (I've added a contact with this number and when in the dialer I can long press on the number as select edit number before calling to take me to this screen)
In this menu there are options to see phone and battery information as well as usage statistics for apps. The best battery option is "battery history" this shows you what apps are using your battery for various things such as network and processor usage. You can see this data for since you last rebooted your phone, unplugged it or for the whole life of the phone.
The first important part is "other usage", "running" shows you the percentage of the time your phone has been awake and doing stuff, "screen on" is the percentage of time your screen has been on, the difference between these two is when your phone has the screen is turned off but the phone is still working such as when syncing. Ideally you want these two percentages to be as close together as possible but it depends on how much syncing you have going on automatically in the background. If your running percentage is at or near 100% then an app is keeping your phone awake and using battery.
Next we have "partial awake use", this is what as been running in the background when you have the screen turned off and any apps that process or sync in the background would be listed here, the longer the bar, the bigger the drain on your battery. On my phone now the biggest bar by far is android system but it is still only small.
With "sensor usage" this is what has been using your sensors, games that use the sensors will feature heavily here.
"Gps usage" is again pretty self explanatory, whatever has been using gps.
"Network usage" was a real eye opener for me, I found out that an app was downloading megs of data all day and dwarfed all the other bars and was the reason for my bad battery life. Here the blue part of the bar is download and the red part is upload.
And lastly "cpu usage" on mine these are all practically non-existent but if anything is using massive amounts of processing it will show up here.
I only found out about this the other day but it has helped my battery life substantially, I used to take it off charge in the morning and be down to around 60% by lunch time, now I'm at 98%. I did this by uninstalling any apps that used too much battery and that I didn't really use very much as well as the vampire apps that were running and syncing continuously in the background, I also reduced the frequency at which some of my services such as stocks, email and weather synced, and used it on a low brightness when possible.
This is my first android device and I can now happily use it without the fear of running out of battery before the days end

Wow, thanks andybut85, that was a very informative post!

If you download Spare Parts from the Market it gives you access to the same info - instead of 'dialing' to test mode.

My biggest is "Calendar" (54mins from Boot, compared to 1min for Andriod System!)
What Calendar could this be? Im syncing from Google Calendar, so will it be that? If so, wouldnt my email syncing show up as constantly on too?
Or could it be some other App that is making it run constantly?
Any help gratefully received.

Have a look for "Total in all time" with mine the calendar is roughly half that of android system, it could be that recently your calendar has had to sync for a long time, this could be a one off or if it's still high for the total time it could be a deeper problem. You could also try rebooting and seeing if it occurs again.

I'm still having problems with battery drain.
My Desire will not last a day
Installed Juiceplotter to find out when and why my battery drops so fast.
See attached image.
The battery drains very fast when i USE the phone, so when the screen is on. (20% in one hour)
I have two push email account activated, one with the HTC Exchange, and one with TouchDown.
But that doesn't explain the drops when phone is active.
Anyone else having this kind of batterydrain ?

I have positive "story" about battery too. Im on second charging. Saturday at 1:00 Im unplug it from charger and now 34h later Im on 7/10 battery.
Im make few calls(cca. 10 calls long 1-3min), few times(cca. 3-5x) check emails accounts(4 pop3 email accountes), quick test sygic navigation, little search on market(install calendar widget and some other app), and play few levels of Teeter...
3G is turned ON
GPS, WIFI is turned OFF
Also automatic sync is for most things disabled or setup to sync 1x per day...

Hmm Can't say I'm impressed by my battery life... it dropped 20% overnight..
I''ll keep an eye out on what's running and see if i can fine tune, but turning things off seems to be a bit pointless as it is made for use not just sit on a desk being pretty.

yep, that sounds highly plausible. Bad or weak connections to the network (especially mobile internet connections) will really drain a battery as the phone needs to use more power to maintain adequate connection strength.
you can check your signal strength in the "settings / network strength" section. I notice in good 3G areas my connection is -95dBm or higher. At work (which is in some sort of black spot in Dublin) I only get EDGE connection and my signal strength is about -80 to -85dBm. I bet this makes a big difference to battery life, especially if I try browsing or data connection.

my signal strength at work is -91 dbm...
i'm guessing bigger numbers are worse?

spare parts showed me that "media" was using the network a lot, bowever i cant work out what this corresponds to, it says DRM protected content storage, download manager and media storage. shows as having downloaded several megs
i use spotify for music, anyone any ides what these could be?
thanks

only guess but i'd say its spotify.. i have used servcies like that in the past on my pc.. and they sometimes have a lot of downloading going on that you dont even ask for!... worth checking out..

yes it could be, but spotify also comes up as a separate user of resources and i tested it since unplugging when spotify wasnt running and "media" still comes up as the biggest user.
makes me think that its not spotify

HTC Desire Battery Life

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 .

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“

also found this on a swedish website (i useed google translate, to lazy to manually translate it)
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.

[Q] Battery issue on Wildfire S

Hi,
after running for 15 hours, one phone call for 2 min, and about 8 sms
and nothing more still remain 45% from 100%.
is that normal or it is something wrong?
wifi, gps, and bluetooth are off, and not many apps are working in background.
no livebackground or something else.
it seems to me, it is very less for such a phone, or I am wrong?
or are there some settings, which need to set to have a longer battery live?
thanks

Hi,
I saw that the dialer use 97% from the Battery! I had the whole day one call for 2 minutes.
is there someone else with such dialer usage?
thanks

I too am seeing that the dialler is using 97% of battery with only one short call made. However, I have so far and still counting got 3d 18h out of my first battery charge. (This is a new phone) This is with everything turned off mind you as I wanted to see the best time achievable with only phone functions active. Once the battery is run down I will re-charge and turn internet on etc.
It's funny that you too have "97%"??

very strange.
could someone post a normal state, how it supposed to be?
thanks

Hey i think you people don't know how the battery use calculate the battery usage in Android.
This is how it calculate
Suppose you had power on the phone then and you are using 3 apps like
1.dialer
2.wifi
3.display
then from above 3 which is the most used app the battery usage will give it more percentage.(But you will not see any 97 % if you are using 5-6 activities)The more the number of apps the less the percentage of each Activity.
The region why you are seeing 97% on battery usage about dialer is that you are using only dialer nothing else.If You use use gallary,wifi,bluetooth,calls,maps etc all together then battery usage will show you 15 to 20 % in each.
To increase battery life calibrate you battery.(let the battery discharge once and recharge it without power on and without any break)
In this forum i had seen that some are geting 4 days of battery with moderate usage and some getting only 1 day.You Had not calibrated your battery.Every Android mobile needs battery calibration atleast once in 1 month.

hi shreyasharusia
yesterday I made a reset, and I calibrate the phone.
Now I have following situation:
Dialer 41%
Cell Standby 29%
Phone Idle 28%
display 2%
android system 2%
Today I made just on call for 2 min, and I have 98%
do you think somthing is wrong with it?
thanks

could be a bug with the sense causing the battery life to be short. I usually let my phone discharge every day before I charge it for the next day. As I am usually using my phone every day the battery usually lats a day at the maximum this is usually because i am always listening to music or texting people.

now I have again this situation.
I did nothing with the phone. just one call for 2 min and 2 text, thats it.
dialer 95%
cell standby 3%
phone idle 3%
so then it is wrong to have the dialer on 95% right?

that's not possible.Battery use limits to 100 % not 101%. 95+3+3 = 101.And in your first post 41+29+28+2+2 = 102.How it can be possible .
Also check is your connection is 3g or 2g.You get your battery life according to it.

.... I know, but it is fact
I was surprised too....)
I will search for a screenshot tool, and I will post it soon....
by the way, I check it with Advanced Task Manager, maybe this tool is wrong?
I use 2G only. I wouldn't be suprised if bluetooth and wlan would be on, and after a work day the battery is empty, but for one call and 2 text?
as for now, the Task Manager and a File Manager is installed, the rest is all on default.
thanks

Use Shootme for screenshot. And Take it to service center for getting low battery issue.

Hey try juice defender.It really works

Hi shreyasharusia
I need to be root to run this tool. is there another that I can use without being root?
Anyway now I have following situation.
Dialer 96%
Cell Standby 3%
Phone Idle 3%
I will try now the other tool, which do you recommend to me...
thanks by the way
but just to clear it, to have the dialer on 96% is wrong, right?

Hi, im new htc wildfire s user, barely a week. Before my battery usage showed lots of things but now theres Dialer 97%, Cell Standby 2 %, and Phone idle 2 %. Whats going on :S? Im releaved that im not the only one. Can somebody please help me im begging

My girlfriend's wildfire s' battery life is really bad. At first it was like 16 hours, but that was when it was in a really heavy use. Now it lasts only for about 12 hours with very minimal use: a couple sms' and little calling. In fact the usage doesn't even affect the battery life, as it drains at a constant rate. The values are _always_ the same: Dialer takes 49%, Android system 49%, Idle 2% It doesn't even show how much the display is using!

[SOLVED] this battery issue
Hello everyone who is experiencing really massive battery drain on wildfire S.
Symptoms:
1. you own wildfire S
2. in battery stats the "dialer" is on top (eg. 97%)
3. you have made a call recently
4. experiencing battery drain about 30-50% per hour.
Cause:
Maybe it really surprises you (or your girlfriend), but you are most probably making a phone call. The new wildfire's dialer is just a bit crappy. When you dial a number and then want to hang up, you have to do it by correct button (the red "hang-up" button). There is also a possibility to "terminate the call" by pressing the "back" button on the bottom, but in this case your call is not terminated at all, but dialer is running now in the background. The nice example is when you are calling a buddy and then you hang-up(using back button) after you realized that you are being redirected to voicemail. By doing this you are still talking to a voicemail for a period of time until the call is terminated automatically by that particular carrier.
Solution:
Use the red button to terminate the phone call. Check the logs and you will see if this is your case.
If you find this post helping to you, just say "Thanks" ---->

does anyone know the pin diagram for the battery?
I just want to know how the android takes the data from the battery.

For users experiencing massive battery drain after making a call and the infamous "Dialer" process is showing up in the battery, you need to follow the greatest battery saving top found in this thread. impreza_rs posted this solution taken from the HTC website:
"connect the phone to the charger with the phone powered on, and allow the phone to charge until the notification LED is green, indicating the device is fully charged. Disconnect the phone from the charger, and power it off. Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the notification LED is green. Disconnect the phone from the charger and power it on. Once the phone is powered completely on, power it off again and reconnect it to the charger until the notification LED is green. Disconnect the phone, power it on, and use it. You need to use this sequence only once"
I do this process every time I flash a new rom on my device and it works flawlessly. A little tedious, but you only have to do this once and you are good to go.

Battery drain <90 and below..

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 %.

Battery percentage dives suddenly

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.
