Samsung Galaxy S II International
Samsung Android 2.3.6 update via KIES
Charged 100% and unplugged since 8am.
66% battery left on 2.06pm.
Display mostly is off. Just random short on for checking.
Is that normal?

Short answer: Yes, its normal
Long answer: Battery stats are measured in % of the battery that has been depleted. In this case you've used 34% of your battery and from that 34%, your display has used 43% of it.
Think it this way: Android doesn't measure the total battery, it just takes how much battery has been consumed from full charged and with that number, it splits it down to see which apps/process have consumed battery in that time.
For example: If you fully charge your phone, you unplug it, use the screen for 5 minutes and check the battery stats, display will be probably nearer than 100%.
You could dl betterbatterystats and check out whats consuming your battery. I dont think its supposed to be draining that quickly.. ocassionally,an app might not turn off properly and hogs the processor. what you can do is go to the task manager and see whether anything is in red..
Display looks about right, 33 minutes of screen on used about 15% of total battery.
Are you listen to MP3 or doing somthing else non-stop? Your phone is awake most of the time.
Someone said it before, but its a percentage. If you just leave your phone on standby with the screen off then Cell Standby will be at the top. Comprende? Good. Either that or your phone is possessed by a demon which turns on your screen and intentionally wastes your battery. But its probably the first one.

My battery life was very good in Mini. I used the phone for normal talking (around 30 mins) and 3-4 hrs of GPRS and battery wwas kept around 20-30% at
10PM after fully charged at 7AM. At that time the battery usage status showed something like this.
Display -40-50%
Android System 10%
Cell Standby 2-5%
Phone Idle 2-5%
Others (not remebering)-the remaining
Suddenly two days ago my battery started dischrging very fast and my full charge at 7AM came to zero at 4.30PM with similar use as stated above. But this time the battery usage shows something like this and consumption always remains highest by phone idle & cell standby parameters.
Phone Idle 40%
Cell Standby 30%
Android System 8%
Display 20%
Others - remaining
Now, my battery is draining a lot faster than it ever had two days back.
My battery had consistently been draining at around 1% per hour idle until today. Now I'm seeing it drop 5% in LESS than an hour while idle (idle meaning the screen shuts off and I don't use it).
So my question is, what do Cell Standby and Phone Idle mean? Previously they had both been 2-5% and my idle battery use was excellent. But today they both shot up to the 30-50% range and I'm thinking this may be the cause for the excessive battery drain even while the phone is sleeping.
I have not changed anything during these two days. But again to be sure I "Factory Reset" the phone and reinstalled all the software again but found the problem persisting. Moreover, during my travel to office (which takes about two hours) I find battery drain is minimum and same as my earlier days, i.e., it drains very slowly but once I enter my office hall the rate of drainage increases, But previously in the hall also the drainage rate was very low.
My queston is what may be the cause of this?
The only change which I feel is deterioration is signal level because the calls now frequently gets disrupted which was not the case earlier. Can this be the only cause for such high battery drainage ?
An exactly similar experience can be found in some other blog whose link is below ( for reference only)

Anticipating some advice/solution for improvement from the geeks here.
Thanks
i noticed i had the same issue whenever i installed some apps from the market...i noticed in particular a data counter to screen my phone bills and Quick Profiles.
So i suggest to think abotu the last installed apps and try to remove them one by one until you find the guilty one.
Remember afer uninstall to reboot your phone or you won't notice any difference
Have you recently rooted the phone? When I did mine I found there was a shell process left running that was eating battery (but doesn't show in the battery info screen) - Turning off and on again sorted that out
Thanks for reply. I will try your advices. But today I morning I switched off my charging at 4.45 AM and now at 6.37AM I am seeing my battery at 99% ot bad. Let me see throughout the day.
Even i am experiencing this problem
Phone Idle is 59% and Cell standby 37% for me?
Now i have removed all task managers and Info apps
lets see what happens to the battery life
@acemadmav
Your advise helped me to track my problem. I also use a Data Tracker software which was refreshed at 2 min and was the cause of battery drain. Now I have set it to 30 mins and my phone is back to full battery strength. Discharge started at 7.30AM after full charge. Attended not less than 45 mins of call, an hour of GPRS and I am still at 50% at 10PM.
@tejagamer
My Phone idle & Cell Standby is still high at 30% and 25% respectively. I googled about this and found that "Phone Idle" is the state when phone uses minimum battery required to keep the electronics of the phone alive and "Cell Standby" is battery consumed for communicating with cell towers in standby mode. Finally, when battery consumption is ok the percentage used by Phone Idle & Cell Standby doesn't matter.
Thanks

glad to help...it's been some months i'm "testing" my X10 mini about this kind of things, so i'm getting used to track down problems on my phone
OK, so here's the deal:
Had my S2 for about a month now, and apart from the battery draining faster then would be nice this phone is an absolute killer cool thing
But now here is the issue:
In the month I had this phone I had 3 occasions of the battery draining to empty while it is ON the original wall-charger. Do describe the most recent case:
Im at work, and I see the battery could use some charging soon. So I plug it in, leave it for a bit with screen turned off. A bit later I pick it up whilst still in charger to do some minour things on it. After a few minutes (phone very hot in mean time, but known issue) it gives me a pop-up that I need to plug in the charger which it is already on. So I check my Juice Plotter and notice that indeed it sees it is on the charger, but the line which shows you the level your battery is charged is coloured red and has been dropping just as fast as before I plugged it in. Near critically empty?
So to check if some app is draining the juice in the background i closes all running services and apps and leave it for a moment. I check: only about 1 percent charge left? O - M - G.
So i did what I did in previous 2 cases: Turn phone off to get it charged to at least about 20% (how nice that someone/something else is forcing me to be unreachable by phone ). When I turn it back on at that point, I check juiceplotter first... No real changes or battery charging for first maybe 5 minutes (it just stays at a flatline level) and then finally it starts charging again slowly but steadily.
What's the deal here?
Since 1st time this happened i started keeping my home screen as clean as possible and such to be as energy-efficient as possible. Barely use screen-brightness (by the way the auto-brightness sucks). On 1st page of homescreen I have the Juice plotter widget showing me battery depletion / battery charge time levels. Funny that in the explained problem cases you can actually see the time till charged getting longer and longer by the minute :S
And I don't even view anything in 3D, on leedroid, and music and stuff drains the battery quick
Normal?
People often get confused by battery use percentages... It took me a while too, but maybe this can help...
Say you're sitting at 90% left of your battery... that means 10% was drained. Looking at battery use only refers to that 10%, not the whole 100%.
So... if the screen reads 74% and your battery is sitting at 90%, what it is telling you is 74% OF the 10% used was from the screen.
And no matter what, any phone or tablet's screen is going to use the majority of the battery unless it's e-ink (even then it's a good possibility). I wouldn't stress to much about it. You can reduce this by using autobrightness or lowering the brightness than it is.
If you're frustrated with the battery in general, turn off best wifi performance and turn off always on data.
Also, leedroid has a terrible battery life.
hi guys , i got some problem with the information displayed for my razr maxx. the thing is the battery usage curve won't change for the first 10% of power drain, and the awake bar and screen on bar are full. but when the battery drops to 80% and below, the curve starts to count from the 80% position, what is going on? how can i fix it ?
here is the screenshot
How many times have you already charged that battery from 0% to 100% and drained it back again to 0%?
Seems like a simple calibration issue that should have no effect in real world battery performance.
Had that too. If you want to know more about this, look up "batterystats.bin".
So, if you haven't done what I said in the first line, do it and report back.
i have tried delete the .bin file bwfore, nothing changed. i think i will try to charge it from 0to 100again see if there will be any change. btw will the battery calibration apps solve this?
http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/
Read that. You don't have to do anything, just let your razr get some charge cycles and the readouts will be right. Remember: There is no need to tinker with this, as this has no effect except for cosmetic terms.
thanks for the information. one more thing, the battery indicator always shows that the screen on and awake time are the same, even after i turn off the screen and play music for an hour. is this normal? or the system keeps recognizing the status of the screen as on? how should i deal with this?
I would just wait a few days (read: charge cycles) and look again. Indeed strange, but if your battery doesn't get drained this also seems just to be another cosmetic issue.
actually it seems it has been more energy draining than before. it wouldn't drop 1% when i turned on flight mode at night and checked it in the morning. but now even i turn on flight mode it drops about 5% next morning.

Don't count on the battery percentage today. Look again tomorrow/after some charge cycles.
The battery readouts need to be calibrated to display the correct battery level.
I had the same "issues" (in fact, those don't seem to be real issues) and they went away. I assume your razr will behave the same as mine
Is the phone still new? I know mine was a little wonky until the charging and the meter apparently calibrated themselves to Maxx's battery Ever since, it's been very accurate.
yes it is still new. i got it about half a month ago. just got it charged to 100% from 0%. gonna see what will happen。
Basically as the title says, I've bought a "refurbished" one, but I'm not sure whether it's faulty, or whether this is just the average battery life of one of these things!
Woke up at 6am, I used it for about 30 mins this morning on facebook/ebay/bbc news through wifi. Send about 20 txt messages, 10 minutes on the phone. ANother 30 mins browsing/facebook on my lunch break. 12 hours later it's sitting at 17 hours battery life. And it's been on power save mode the WHOLE time. Is this just something I'm going to need to get used to or is mine just a dud?
LOVE the phone otherwise though
If you download Better Battery Stats app (either in the play store, or on this site here http://forum.xda-developers.com/showthread.php?t=1179809), and GSam battery monitor you can check up if certain apps are causing your battery to drain.
I had a really bad drain on my battery whilst in standby mode, and these battery apps helped show me that a few rogue apps were preventing my GS3 from going into deep sleep and the battery was draining even with the screen off.
I would say its more than likely an app causing your battery drain rather than a faulty phone. I spent weeks thinking I had a faulty phone then discovered these battery apps to find the problem... my battery lasts very well now. It just takes some patience to find the culprit.
What was your screen on time? Settings >> Battery >> click on screen and it will tell you the screen on time.
When you use GSam battery monitor, pay particular attention to the apps sections 'View time held awake' and 'View num times waking device'

Biggest culprit is usually having facebook sync on in the background, check that in settings. It's an awful app. I use other things like Seesmic to check facebook now.
