I seem to use battery charge due to 'cell standby' even if mobile data is off. Checking 'restrict background data' under 'data usage' does reduce the drain - but not completely. The drain is about the same as 'Android system' when the device is left on but unused. What is draining the battery - and is it something I can disable or freeze?

I just got a new desire after my previous one got stolen.
I found out the battery of my new handset last dramatically less than the previous one...it doesn't even last one day!
I reduced the screen brightness to 20% and deactivated the 3g mobile data but on the battery screen usage it says as follows:
cell standby 31%
phone idle 30%
android system 23%
display 7%
voice calls 5%
internet 2%
dialer 2%
why would the usage be so high when the phone is in standby? why would it be so high for the phone idle?
I also found out it takes ages to shut down completely...is there anything running underneath that I can stop?
please advice the optimization setting to try to improve battery life please
thanks in advance
The percentages just express which parts of the battery drain (lets say you are on 68% --> 32% drained) have been used by which activity of the phone (so they are not absolute but relativ values).
In a combination of your and my example this would mean.
30% cell standby --> 30% of 32% is at least only 1/9th of the whole battery.
Hope you get what i am trying to explain
I see where you come from but I don't think this can explain why I need to charge it every 5 hours.
Have you calibrated it,?? Search battery calibration, and try that.
Is your phone rooted michaelss16???
no my phone is not rooted but I think I managed to sort it out!
set it up as follows:
MENU> settings>wireless and network>wi-fi seettings>menu>advanced> wi-fi sleep policy> after 15 minutes
MENU> settings> sound and display>brightness> uncheck automatic brightness> reduce brightness manually by sliding it down to no more than 30%
MENU> settings> sound and display>screen timeout> set it no more than 1 minute
MENU>settings>account and sync>uncheck background data (it is possible to check it manually by refreshing it everytime is needed)
MENU>settings> Location> uncheck both "use wireless networks" and " use GPS satellites"
MENU> friendstream>menu>settings>Accounts and sync>for any of your active accounts(facebook, flickr, twitter) go to account settings>update schedule>set it up not more often than every 4 hours. (you can update it manually anytime you want)
MENU>Latitude>menu>privacy>turn off latitude. (it is possible to turn it on when maps app is needed...don't need it on all the time)
MENU>Stocks>menu>advanced>uncheck auto-sync data (you can refresh as needed)
MENU>weather>menu>settings>uncheck update automatically (agai nit is possible to update it manually by hitting refresh button)
In addition when in charge at night I shut mobile network off (I don't check updates-mail or post if I sleep)
Since I don't expect any phone call at night I turned the radio off by dialing *#*#4636#*#* >phone information>turn off radio (don't do it if a phone call is expected).
it is also possible to access battery history to check through all the processes running on the background and using power,CPU memory and bandwidth. ( the menu settings battery information refer only to the TIME of each process draining the battery and not the amount of battery drained by each process).
Now I understand why phone idle and standby was so high when checked in the morning..they are the only processes running at night when the phone is in charge if it is on).
Hope it can be usefull ....now it says 14h 52m and 13s since unplugged and battery level is still 54!

Basically you just did what I always recommended you, update manually all the applications, except for the radio, I just turn off the mobile data so I can still receive calls...
Battery drain and overclocking
I rooted my phone and installed Runnymede AIO v6.0.4.1. After installing i guess a default value has been set for the OCD as around 996000. I later changed it to the highest value and played a game. with in minutes my battery drained to 30% from 70%.
I mainly rooted my phone so that the memory constraint in HTC Desire can be done with so that i could install more and more apps and games.
I NEED TO PLAY GAMES and WHAT WOULD BE THE BEST VALUE to keep FOR OCD, so that my phone is fast and i could play games without even a minor lag.
And i also have another problem, in call history i dont see names against the calls made. However i can see those people in my contact list with names and numbers, but in call history i see only numbers and a + sign asking me to save to contacts.........
Can anyone help??

Does the "new thread" button not work for you? Hijackers should be prosecuted
For long time I was using Starburst ROM (stock + D2SD on SNQ kernel). It was really good in performance and battery saving due to basic Sense 2.2. I could play AngryBirds couple hours long. The major factor was screen brightness to be dimmed a bit. Since I dropped gaming behavior I had no experience with other ROMs/kernels I was trying.

Hi,
I updated to lollipop a few days back.
Since the update the phone battery dies in few hours even in idle mode
I hav tried keeping gps off wifi off, location off
I also disabled google play store, maps, play services etc.
Better battery stats and gsam monitor show that the massive drain is due to "android system", which causes massive drain.
it keeps cpu awake for long.
I have images now showing the same.
pLEASE help
I have a T999V (Wind Mobile) running TouchWiz 4.4 (with towel root) on the Wind Mobile network. This phone has a brand new Anker 2200mAh battery.
Unfortunately, my battery life is under 9hrs. I get about 2hrs of screen on time, which consumes about 20% of battery, and then the combination of Android System, Android OS, Google Services will consume a whopping 50% battery.
I have Wakelock Detector, BetterBatteryStats and GSam Battery Monitor installed.
How do we diagnose what's causing this problem?
I'm usually at home, using my home WIFI. Other issues I've noticed with my phone are that I notice slowdowns sometimes with Swiftkey, when a lot of app updates are going on, Google Maps, Google Chrome address bar. This phone did have water damage at some point and I had to have the power button replaced. Could this affect the battery drainage and or the slowdowns?

Thats about what I get with a new stock battery. If I leave it on and roaming all day while at work and I get no signal, I'm down to 40%, few hours of screen time. airplane mode all day at least gets me to 60-70% by the end of the day.
Is what it is. lol. Plague of all smartphones.
you can't expect a good battery life that you desire. because samsung s3 has a powerful CPU, and a good high resolution screen which will take power to run. You will be lucky to get about 5 hours on a stock battery. If you really want to do stuff.. try under clocking the CPU too 1GHZ or below. that would probably give you 1-2 hour extra battery but other than that..
Try the basics: - GPS off, location off, Data off. etc.

Dude, your battery is normal, we all have the same or similar battery time.
If your concerned with battery life, try an extended battery..
In 3hrs I've used 70% of the battery with 2.5hrs of screen on time. I find it hard to accept that this is normal for these phones.

What were you doing during those 2.5hrs of screen time? With wifi or 4g on, I can kill mine in a few hours, with a new battery. Don't know what you expect.
Disable Google now from the app settings, in WiFi advanced settings make sure 'always scanning' is disabled, only sync what is necessary from the accounts section in stock settings app, only enable WiFi, Bluetooth, etc, when you use it.
First, bigger battery: http://www.amazon.com/dp/9838427837/
Second, Turn off background WiFi scanning (in CM11, Settings / WiFi / ::: menu (lower right) / Advanced / uncheck Network notification, uncheck Keep Wi-Fi on during sleep, uncheck Scanning always available)
Third, Deny wake rights for Google Play Services (in CM11, Settings / Privacy / Privacy Guard / ::: menu (top right) / check Show built-in apps / long-press Google play services / scroll down to Wake up and Deny , scroll down to Keep awake and Deny / BACK once / long-press Google Services Framework / deny Keep awake )
That'll get you 2 days in MY usage
Hi,
to make sure I have a "clean" system, I reset my KK to factory and flashed the full 6.0 image via adb.
Now after doing my peronal settings I experience serious problem with battery drain during sleep ~2%/h related to WiFi.
I tried "keep WiFi on during sleep" at "always", "only when connected" and "never" which makes no difference.
On the battery graph I can see that WiFi is constantly on, allthough it is reported with 2% only.
Only if I switch to flight mode I can see that WiFi is off and the battery drain comes to an expected low level.
I checked with GSam Battery Monitor that there are no wakelocks and in generall it looks like MM just ignores the WiFi setting, still I can't image what uses the WiFi so extensively during sleep. On my Lenovo I have to keep the WiFi active to not get extensive battery drain and still have only 6%/day battery drain in sleep.
Anyone with similar resuts? Hints? Tips?

So as the title says, I am noticing that my A70 battery is draining really fast. For example, in the last 15-20 mins I've been browsing Reddit and Facebook on 15-20% brightness, wifi on, mobile data off, power saving on, reduce animations on, nearly all 'Advanced features' off, no background apps running and my battery has gone from 81% to 74%. Is there anything I can do to maximise battery life? I really dont think I should be getting this much battery drain with the settings i have on.
Go into battery in the settings and press the battery usage button to see which apps are doing it.
