My battery life increased after upgrading to gingerbread. I can usually go through the day (15 hours) with 3g always on, twitter and fb sync on, with light gaming and surfing of the web, 75% brightness.
My record was 2 days 9 hours with 0% brightness, no 3g, only wifi, no gaming, twitter and fb sync on.
For your percentage problem, you can try draining your battery, then when the phone shuts down, hold the power button to switch it on again. Start up an intensive app like a game to further drain the power. Do this until the phone does not start up (no bootscreen), then plug into the charger and charge overnight. DO NOT turn the phone on during the charge. When you turn on your phone after the overnight charge, it should read 100%
I am not too sure what triggers this, but its likely due to battery memory or something, although this should not be happening for lithium batteries. Maybe its a software fault. Do this every month or so to hit that 100% indicator. It is not advisable to do this all the time as draining the battery completely MAY damage the battery over time. Cheers!
How did you manage to get pass 2days of usage?

Hey,
I'm also having the same issue. Off the charger, BANG! 96% or so, sometimes more. My phone will be at 90% after like 3 texts. Its only had 5 charges mind you, I know there's a "conditioning" time but still, is this normal? I can almost say a text is a percent...my 3gs had more batt life after 1yr... now that's saying something...haha
I can almost watch it drain with the screen on...like 60 secs is a percent or 2...not cool...
Maybe I can do the "Desire Battery Calibration" procedure after a few more full charges...might make a diff...what do you guys think? I may be jumping the gun here...
Thanks in advance.
I remember someone said modern phones are designed not to keep on charging after reaching 100% and resume only after dropping to certain level, maybe 9x%. That could be the reason why I see different percentage left every day I unplug the phone in the morning. But my last Hero always show 100%.

That sounds right, because it drops from 100% to 96% after a few seconds, and its direct from 100 to 96.
But if you put the charger back it taks a couple of minuts to get from 96% to 99% and about 10 minuts to go from 99% to 100%
As far as i have noticed, this was the issue with X100 too after 2.1 update-
Once connected to the wall socket, the phone charges to 100% and starts dropping.
it does not charge again unless you reconnect the charger.
till the time it is connected, it will display as 100% but once you remove it drops to how much ever time has been spent since it reached 100%.
why that happens, i really don't know.
Ideally the phone should continue charging if the level is below 100. anyways....
about the battery backup, i think 13-15 hours is quite good for a phone with this display and capabilities.
with 3g, a little gaming, surfing, chatting etc. this should really do.
in fact, post the 2.3.3 update, the battery life has definitely increased.

So you think that having a 13hrs ++ battery life is good enough?More advice please..thanks..

I am on a VzW Inc2 w/ Froyo so not sure how applicable any of this is for you guys...but anyway....
My battery life is fantastic. I too see the 100% down to whatever after unplugging - I am pretty sure this is like others have said; once it reaches 100% during charging it stops charging and does not start again until you unplug and it re-plug it in. I know in my case charging from dead to 100% only takes like 3 or 4 hours. So if you are plugging your phone in when you go to bed it is probably hitting 100% after 3-4 hours and then the rest of the night it is draining down...
I have found JuiceDefender Ultimate and JuicePlotter to be huge helps to me in decreasing battery drain (JD) and understanding what uses the battery (JP).
Also just going into settings, About Phone, Battery, Battery use - this helps understand what is using it.
*Note: JuiceDefender Ultimate can create more problems than good if you are not willing to take the time to learn/set it up.
Prior to using JD and JP I would generally make it through the day, sometimes have a bit of power left over. After using these I always make it through the day, and sometimes through 2 days.
But let's not kid anyone - what JD does you CAN do manually...but more than likely wont or will forget. So for anyone that doesnt want to use JD, do you leave your WiFi on all the time, or do you switch it on/off? Leaving it on all the time drains battery. When WiFi is available, do you use it? I have found WiFi on this phone to use a lot less battery than 3G.
Probably my favorite function of JD I have it disable 3G and WiFi when the screen is off (for getting emails, updates, etc... you can set a schedule where it turns it back on during intervals or whatever).
Also I like the WiFi Location setting - you can teach it where you use WiFi and it will automatically turn WiFi on/off based on your location.
Anyway - my guess is if you are having low battery life, either you are using the device a lot more than you think (voice calls use a lot of battery), you have things syncing too often, or you are leaving radios/etc... on all the time that do not need to be on.
I tried to take the charger out at the same time the battery was on 100% and the LCD light went green.
Then the battery stayed at 100% for about 11 minuts and then went down to 99%.
After 3 1/2 houres the battery is at 95%!!!!!!!!
Bagground Data is enabled.
3G is active.
I have mail check every 15 minuts.
Screen brightnes at 40%
Weather update every 1 houre.
I don't use Facebook, Twitter, Stcoks and News.
I don't understand the battery in my IncS...
You guys know that these batteries don't have memory right? So when you charge doesn't matter, your phone just thinks there is that percentage of battery, do a full drain once and then it should back on track. Also, these batteries never get charged to 100%, its a safety precaution or something of that sort. They hover around 94-96% which is why the phone drops down to that area in what seems like a short amount of time. The fact that the phone says 100% when you unplug it is for effect. I used to always think I had battery problems, just stop being so worried about the battery and you'll notice an improvement. Hope this helped.

Also draining them completely flat, as in device won't power on, is the worst thing you can do to them
It sort of kills off a little of the capacity, every time you do it
So to the bloke that recommended it, no it does more damage than good

I'm finding turning to GSM only helps massively. I mean, so it should but I was hoping I didn't have to do this all the time, like I had to with my 3GS... And its a pain in the butt having to change it.
Still cant find a widget that will do it for me...not mobile data, ACTUAL WCDMA-GSM and back...
On the side, if anyone knows of one, please tell! haha
Thanks

I tell you is true, and i don't understand i either!!!
Most of the 17 houres the phone was only in standby and i only read mail twice.
I guess its just a fantastic ROM that Mike1986 has made with no Sense ;-)
I can get a day and a half out of my IncS with heavy use on a pretty regular basis. Set brightness to automatic, switch off unnecessary auto updates, GPS, bluetooth, and keep volume down or off in games. My screen timeout is 1 min (reduce for longer battery life), and I have always on internet switched off. I generally leave my Wi-Fi on a lot by mistake but don't find this to affect things too much really.
You will get 96% a lot after a charge as it is bad for your battery to stay plugged in when it's fully charged, so the s/w on HTC phone switch the charge off for a little while so it runs down a little and back up again. I had Hero before and that did this as well.
juice defender ultimate is excellent in my experience.
i had it set to switch on data every 5mins for 15secs to receive notifications and do updates (i have quite lot syncing - twitter, fb, sky news widgets x2, weather) and i would sometimes have gotten 30 hours out of the phone (ie. i wouldnt have charged it 2 nights in a row sometimes), but always easily 1 full day.
im getting sick of having to use JD though, because i figured something HAD to be wrong as my battery would drain in maybe 5-8 hours without JD which I just dont think is good enough and so could not be how its meant to be.
i then read about some people having problems with cyanogen rom battery drain, and that if you switch off android market notifications, it solves it.
so i tried it, charged my phone to 99% again and im now at 82% after 5 hours 10mins, which means if i keep using the phone at this rate, ill make it 25 hours - which is more than good enough for me. (~and i still have all the same stuff syncing as before, except market notifications~)
also i have wifi set to never sleep, so its always on. (its my ideal that everything that you buy the phone for should be able to be kept on 24/7, eg data, gps etc always on - so i keep them like that. bluetooth i dont use though - if i can make it through the day on a charge with decent use, im happy)
try it.
im calling BS on jkolner btw - pics or it didnt happen
Does anybody experience a 3% to 5% battery drain just a few minutes after charging the battery to 100%? It has already reached 100% so I already unplugged it from the charger, but then I noticed after a few minutes, it went down to 97% already, and then in 10 minutes, it's already down to 96%. In 3 hours, it's down to 84%; in 7 hours, it's down to 38% and that's just on standby mode with Wifi/Bluetooth OFF, 3G OFF, GSM only. I've been experiencing this problem for the past few days now. I've already conditioned my battery, charging it to a full charge (100%) after draining the battery until it shuts the phone off. I only charge the battery while the phone is off and usually it takes about 3 to 4 hours maximum to charge it to 100%.
The longest time it reached was 12 hours (battery unplugged from charger) and that is with light use, such as Wifi is only on for a couple of hours, so basically just 2 hours web browsing and skype, 10-20 text messages and 30 minutes to 1 hour browsing the photo gallery or watching videos. No phone calls and 3G is off. The rest of the day, the phone is just on standby mode. I only have at most 10 widgets on the home screen. I have Avast Antivirus running in the background.
I am currently using Easy Battery Saver, Easy Task Killer, GO Task Manager and Battery Monitor Widget. I've uninstalled Juice Defender since I don't think it helps that much when it comes to the battery drain. Currently, the power saving option (available on Note) is enabled at 50%.
Wifi and Bluetooth: OFF when not used

Any feedback or comment on this matter would be really much appreciated. Thanks!
From a personal standpoint. Your screenshots shows that your phone had never ever done a deep sleep at all. the 'Awake' mode is continously consistent as well. I guess the probable reason for that is you've installed ''Avast AV" on your phone. It's always running in the background (whenever the phone is ON). From my experiences, Any background application running would always cause wakelocks and the phone would never enter into deep sleep at all.
How bout you try uninstalling some of the background apps your using esp. Avast AV and give it a day to observe if your still having that battery drain issue. (Don't forget after uninstalling or removing those apps, try to wipe dalvik cache and battery stat and restart your phone after.)
and Oh by the way, I am using Juice Defender and contrary to your saying it doesn't help.. IT DOES HELP save battery as I my Note is able to reach 1.5- 2 days of normal use.
Cheers!
Yeah and download betterbatterystats and do some searching on it. With it you can discover what is causing those wakelocks. Search the web for more info on your wakelocks.

I'm using avast and never seen a drain like that. Only time I have is because of background processing. First thing I would do is turn off Background Data
Then as others have said - check batterystats to see where wakelocks are
Plus a rooted phone is a good thing. Titanium backup allowed me to freeze wi-fi sharing which also made a big difference
Finally - clear all caches from Applications menu and reboot

Only picture that shows that is the one with 1 minute 56 sec discharging time, so it was taken shortly after taking charger out. No suprise of it being almost 100% screen on time there if its only 2 minutes
Also installing "cpu spy" will give the cumulative time that your cpu spent at each frequency including deep sleep , mine is showing 88%
John.
Anti virus app is battery hog, I had avast before too, and I uninstalled it after 2 days using. Also that Juice defender, from my test before, it use up more battery than it saved. turning on and off those 3G/Wifi thing is using up alot of battery. and you know what? even the betterbatterystats use up alot, at least to me, becoz it scan what is up frequently.
Hello! Thank you all so much for your response. I've installed both BetterBatteryStats and CPU Spy and here are the results (please see attachments). Upon checking CPU Spy, it shows there that phone did went to deep sleep, maybe? I'm not quite sure, but it shows on the screenshot that it went to deep sleep for 19%. So does that mean the phone really went to sleep?? I'm sorry to ask this question, since I've never really encountered this problem before with my previous Samsung Wave phone, how will you know that your phone went straight to deep sleep mode?
Also, after 46 minutes or so, the battery went down to 96% already after charging it. The battery drain was already 4% in less than an hour.
@letters_to_cleo: I have not uninstalled Avast yet, since I'm still hesitant to use my phone without an AV. But I will try your suggestion for 1 day and see if there's any battery improvement.
I'm looking forward to your response or suggestions. Thanks again!
i am having problem too with new battery original samsung ( made in japan, finished in korea) previously i use samsung battery made in china, finished in korea. charged it over night with power off. it only last 13hrs. my wife phone can last 30hrs.
i've used batterymix to check the battery usage graph, the usage graph drop very fast compare to my wife phone. i'll post some screen capture of the graphs.
another issue is i used once wifi sharing. after turning switching the wifi sharing off, the wifi sharing service always at the background even after many reboot. how to turn that off??
You might need a new battery. Any rechargeable battery has a finite charging cycle. Just a suggestion.
Hi, all! I just noticed that the battery drains still even during deep sleep mode. After 3 hours or so (during sleep mode according to CPU Spy), the battery went down to 92%. It drains even faster when the phone is in use, especially when Wifi and Bluetooth are on, maybe 2-5% drain in 1 hour.
Maybe there's something wrong with the battery?? It's still a new battery and I can see some improvement each day though, but that's because I use it less each day. Before the battery can only last for 8-10 hours, then it increased to 12 hours, and then to 16-17 hours. BetterBatteryStats' current estimate to empty is 24 hours as of today, but that's because I only used the phone today for only a couple of hours, with 20 minutes Wifi and Bluetooth ON and most of the time, it's on deep sleep mode according to CPU Spy.
What do I do with the results from the Partial Wakelocks? Do I have to disable those apps?? The Kernel Wakelocks didn't show any reference apps running. The screenshots for the Partial and Kernel Wakelocks that were taken a few hours earlier still show the same results after 3 hours.

That would be really bad luck. I got my Note via preorder in Germany at the first day it was sold and since then I charged it everyday, sometimes even twice and there is no difference to the first day. If I get told by Samsung after 6month of normal usage the battery is dead that would be the last Samsung device I bought and I use a lot of Samsung stuff.
@ebichan24
Your last screenshots show between 9:35 and 13:35 5% of battery drain. That's not really a good value but ways lower than before. Did you delete some Apps or what did you change?
And since when occurred this issue? Did you install new Apps before this happened?
On my Note I had this issue sometimes without any changes but it was gone after a reboot.
Gesendet von meinem ARCHOS 101G9 mit Tapatalk 2
Agreed with Kanalcommander.... try a reboot in the first instance.
Others have also noted that it takes a few refresh cycles before the phone more accurately reports battery use. Perhaps what you are reporting is because the phone and battery are new (new ROM or Kernel loaded?)
What I have done in the past is to reboot into CWM recovery then clear the battery stats (in the Advanced menu option) Recharge the battery to 100% until it says to remove charger and then use normally until battery down to around 20%, then recharge the battery to 100% again. Do this over a few days and that may help.
thanks, it is new battery two days old.

I was having similar problems with my new note and finishing full charge in 12 hrs but fixed some things and my last charge gave me 2d6hr seriously..few things i did were stop using live wallpapers! Get badass battery to thoroughly monitor stats and then use zdbox to extend life even much eg. I put phone to auto flymode using that app when its sleeping time rest i am more than satisfied even if on GB LC1 fw..waiting for official premium suite for ics since i recently upgraded from sgs2 using ics i miss that smoothness and much better bat life.. Let me know if can be helpful.. Good luck

That's what I'm currently doing right now, well, actually, what I do is I discharge the battery until it reaches 0% and turns the phone off. And then I charge the phone for 3 hours while it's switched off, I turn it back on again to check if the battery is fully charged and then I unplug it from the charger.
@Kanalcommander
**Did you delete some Apps or what did you change?
I haven't deleted any apps yet since I don't know which app/s to delete. Most of the apps I downloaded in Note were the same apps that I used in my iPhone4 and Samsung phone before.
**And since when occurred this issue?
This issue occurred since the first day I bought the phone, which was a couple of weeks ago. How long does it take to condition a new battery and new phone?? I'm sorry if I have to ask this question, it's just because I never really experienced this problem with my previous smartphones.
**Did you install new Apps before this happened? On my Note I had this issue sometimes without any changes but it was gone after a reboot.
I only installed recently CPU Spy and BetterBatteryStats and that's it. The drain of 5% from 9:35 to 13:35, the phone's just on deep sleep mode. And then from 13:35 to 23:44, it went from 92% to 74% while the phone is on deep sleep mode at 90% according to CPU Spy. That's 18% battery drain. It's just an unacceptable number for me. I tried rebooting the phone already, but every time I do so, just a few minutes after I turned the phone ON, there's already a 1% drain in the battery.
Also, does the battery really drain faster when the Wifi is ON? I've read in other threads that there might be some problem with the recent OS update that Samsung needs to address. Is this true?? Because as you can see on the screenshot below, the battery was still at 74% by 23:44 and then after I turned ON the Wifi and used it until 01:26, the battery went down to 54%. That's already a 20% battery drain in just less than 2 hours. I was only browsing through the Android Store and Skype.
Calibrate your battery in case you flashed any roms and for first usage I got my battery to 0% 3 times then everything is running great for example its at 47% now its 22 now and I have had it off charge since 7 morning..... i have wifi gps and 3g always on and use music player bluetooth and made some calls

My battery (also only a week old) drains quickly too. Can anyone tell me if widgets draw a lot of current? And then is it only the ones on the visible screen or do all widgets draw juice all the time?
I will ask such thing, did you guys check the battery expiration day ? Mostly sibce you got your phone almost a yeae after it was announced you nay get a bad battery, as for widgets the ones that are always active and asking for informatiom. Like location or weather over the internet yes they do eat your battery kinda fast.

Recurring battery drain? - Caused by memory of using app to drain battery?
Hello!
I used a battery drain app when charge left was 30% to accelerate drain to "die out" stage. After I completed the calibration process for unrooted phone as suggested in various sites (charge fully, switch off and charge etc.) I started using it from a 100% stage.
This afternoon when the battery showed 30% I saw in BMW the current flow was in -10ma to -15ma and it started spiking to hundreds. There was no change in settings or usage. From the 30% level it dropped to 10% in an hour and I had to charge again.
Was puzzled why the battery which was dropping around 0.5%/hour in standby earlier to the 30% level suddenly went down hill. My first guess was it was possible some file in the system remembered the previous usage history and replayed it out.
Any suggestions? Anyone faced this before? Everyone says LiOn batteries dont have memory so if anything it has to be the phone.
Thanks!
I have changed my firmware from 10F to 10H as I heard that it is much better. I rooted it and then reset it to factory settings and I deleted some of the bloatware. I used LG gearbox and set the CPU speed to 1000mhz on two cores and used this guide. http://forum.xda-developers.com/showthread.php?t=2048315
In additions, I installed fast dormancy toggle from here. http://forum.xda-developers.com/showthread.php?t=2021248
I charged my battery full to 100% and then unplugged it left it unattended while I went to sleep, wifi and auto sync was switched on and gps,location . My screen display is set to automatic. After 10hours 51 mins I lost 10% so it dropped from 100% to 90% I did not use any screen at that time as I was asleep. After that amount of time I used the phone went on youtube for around 30 mins as it says screen time 35 mins and so the battery dropped to 77%. I browsed the internet a bit further and still carried on youtube after another 20 mins (56 mins) the battery dropped to 68%. When the battery had dropped to 59% I roughly had around 1 hour 20 mins on automatic screen display settings but at this stage, as I used the phone more, the android system had went to the top. Sometimes when I just browse my phone, and just go on facebook and check email the battery % can drop very quickly like 1% every 3 mins, is this normal. I hardly use the screen that much. On the iphone 5 if you use the screen for like 5-6 hours browsing, playing games etc the battery would just drop to only 50%. Some people in this forum are saying that they are only loosing 10% per day, and per sleep they are only loosing like 3% if not then 0%. Is my battery normal running normal?

Looks normal to me.
Don't forget that using wi-fi, and specialy on youtube "drain" some battery. Not only
because of screen quality but also the amount of data that you "download", specialy
if you select best quality videos on your settings.
Facebook is kind of a drainer too, specialy if you have notifications ON, update for 30min. and location service ON too (activates GPS)...
I can tell you that could be better but also that could be worse... depends of what you need to be running in background or not.
What apps you need or not.
Don't believe on everything that people says... some had deleted almost all the apps, others say the battery lasts for days but, the phone spend 90% of the battery life in deep sleep...
O4X have some nice features, like high quality screen and all that cost something, that something is battery
A weak network signal or several signals, that make the phone change or look for signal constantly, also contributes for battery drain...
But your battery life looks pretty normal to me
Hi all! First of all sorry for my english
I've bought my xperia z few days ago and I am experiencing a very low battery life, even without using the device too much. First thing I noticed (when I fully charged the device for the first time) was the the standby time approximately only 5 hours with stamina mode (!!!) and a huge battery drain, something like 1% every 2-3 minutes with only mobile connection (GSM) activated and some browsing (no flash only text), no bravia engine, no video, no application in background, lowest possible light screen and of course stamina mode. After about 2 hours 60% of battery remained. Now I have about 5% and I used it for about 20 minutes of browsing, some game (2D), and nothing more.
I ran a test on the battery but seems in good health.
I should re-calibrate my battery?
N.B.
When I bought it I have used it until the discharge (10-5%) of battery then I've made partial charge up to 50-60% then discharge again (10-5%), afterwards a full charge of about 5-6 hours. Can this have damaged the battery?

I should re-calibrate my battery?
N.B.
When I bought it I have used it until the discharge (10-5%) of battery then I've made partial charge up to 50-60% then discharge again (10-5%), afterwards a full charge of about 5-6 hours. Can this have damaged the battery?

did you update to .434? because some users say that they got a battery drain when they updated to this version,
anyways, ill give you a solution that works for me,,, install " snapdragon batery guru" really helps alot , and you will noticed some battery improvements, much better than the power management mode,
p.s. dont use it on gaming to much, and dont remove it to charger often ( even when its not fully charged yet)
If the service test say the, battery is fine, it probably is.
Have you tried factory reset?
It sounds like some app is keeping the device awake (and very active)
Try providing some more info, like battery stats.
You should install wakelock detector or better battery stats and see if there's a bad app. And solve it with greenify or uninstall
Sorry I'm quite noob on android, xperia is my first android device I'm coming from symbian
Yes I updated on .434
For the apps keeping awake, I only saw the "battery usage" menu ad it says: Display 46%, Chrome 11%, Android System 11%, Media Server 10%, Standby 4%
Well to begin with de activate chrome, and all syncing.
Settings > accounts > press account & de activate all automatic synchronisation.
For chrome go to apps > all apps > chrome > deactivate.
Then go to play store download dolphin browser

Charge it and see if battery had improved, it should've , charge it to like 20 see how much drains for 60 minutes without using it. Should be 0% or 1%

ok ill try. Some friends told me to fully discharge then recharge for about 12 hours, can this work?
Another thing, I saw some screen of estimated standby time of xperias in the forum, they are all around 1 day, but mine even with a 100% full charge says only 5 hours, what can be?

Thank you!
It worked very well now it says 2 days without stamina and 4 days (!!!) with stamina. Now I can finally enjoy this awesome phone
I've got a doubt about battery discharging in my phone. When it normally discharges from 100 to 35% everything is in normal, with similar drops every hour for ex. 2 days. But (even in standby) when battery is on app 35% I see very fast drop to 25-20% in couple mins. At the beggining I thought it is maybe broken cell in battery but I notice that around camera surface is warm, not hot. So it is probably matter of software. What drains my battery so fast and always at app 35-30%? Do you have similar issues? I made factory wipe few charging cycles ago but it did not make any changes.
Do you use any of the power management settings like stamina more or....
What apps do you have installed?

Yes, I always use stamina, I switched it off just before taking picture. I use dropbox, GO backup, Network Singal Info, netmonitor, Gmail and one additional mailbox. I have Google backup - off, Hangouty - logged off, google now - off.
Well, I don't use stamina mode anymore. I too had these sudden drops when stamina mode was on.
Try switching off stamina for a couple of cycles.
If you find that there are no drops, then you have your culprit.
So you mean not use stamina at all or switch it off at around app. 50%?
Try without stamina mode.

I've tried once without stamina but I got visible faster discharging so now after update to 4.2.2 I am testing with stamina ON.

Deleting battery stats does nothing. I post this every time I see someone recommend it, but I feel that the point needs driving home until people realise that it is a placebo at best.

my opinion
Sorry, it will not improve your battery, just if you have wrong indicated battery %,it maybe solve that. I solved a problem like that.my battery went from 50% down to 18 in a cuple of min.after deleting the stats and a few charges it was O.

No. The batterystats.bin file has no relation to the percentage displayed in the notification bar. It is used to calculate the usage statistics displayed in the battery usage section of settings. Nothing more. The file is deleted every time the battery is fully or nearly fully charged anyway.
The G+ post I linked to was written by an Android framework engineer, so I think they know their stuff

Ok,maybe i'm wrong,but somehow my problem was solved
I am sure that I hadn't wrong percentages but period of strange drain battery (when % suddenly drops) because I felt warm temperature around camera. So I suspect any strange thread/wakelock/trigger.
