Rightyho, so I had a O2U SGS with its original firmware, had a bit of an issue with the leaked Froyo that changed the product code but managed to get it back and used JM1.
So JPO came out, thought id try it out. Result: Awful battery life.
JP5 came out (the O2 UK version). Result: still awful battery life.
Thought id try JPA. Result: still awful battery life.
Done all the battery optimisations, deleted the battery stats etc.
Back on JM1 today, battery is at 89% after a 100% 4 hours ago, witch emails, gmail, facebook, and a few other syncing at 30 to 1hour intervals. This is what battery life should be.
The question is, do i give Froyo another go, or wait till another version of Froyo is released? I do like a lot of the new stuff Froyo has, but i also would like my phone to last more than 12 hours!
Suggestions?
Did you try finding out what was causing the battery drain in those froyo roms? 2-3% drain per hour is very achievable, if I just let my phone idle it would only take maybe 1% an hour. I think something else is causing the problem.
I agree with nwsk ive tried numerous froyos and they have all been good for batery life. Theres a few threads about the gallery app and battery usage.
Im pretty sure its both email and gallery, but dont understand why i am getting the issue when others arent?
Had no issues with batt life on froyo either, If it was me I'd wipe it clean and perform a fresh install, see how the battery is then, assuming you haven't already tried that. If you did then something is sucking the battery, doubt it's email or gallery as mine is syncing constantly and I get about 3% drain per hour, in the evening when I turn syncing off I'm getting about a 1-2% drain per hour. My data network is disabled though, but I have wifi on constantly
Ive done several hard resets again, even done a clean install of JM1 then upgraded straight to JPO and after everything is setup, battery just drains rapidly.
Just because you dont have the issue, doesnt mean it doesnt exist, there are several threads with others reporting the issue;
Battery drains after Froyo update
Battery drain problem/sensor usage
Do you suffer from Gallery Sensor battery drainage?
Froyo emial battery drain issues
Just trying to be helpful, nobody said the issue doesn't exist. Have you tried a custom rom?
Doc custom rom is a good try,
but before hands,
mind share the following info?
1. which email client you use? (Samsung email client? SEA? etc?)
2. which email you try to retrieve (yahoo? msn? outlook exchange? etc?)
3. Do you sync other things like contact, calendar together with the setup?
1. Using default Samsung client for email.
2. Exchange and hotmail account being synced every 30mins.
3. SNS? syncs my facebook once a day, also have a few widgets like facebook and engadget doing a 1 hour sync
These are the settings i have on JM1 then choose in Froyo when i upgrade.

I suspect your Exchange give you the problem.
Froyo Samsung default mail client is a bit picky and it drain the battery at certain condition.
This is the strange issue I encounter when I'm on Froyo Samsung email client, read my update, you may suffer for the same issue.
http://forum.xda-developers.com/showthread.php?t=817842
My advise is
1. Sync only hotmail (btw Samsung Premium Social Hub offer a better integration with Hotmail, do give it a try) , do not setup exchange, let it run for a day, if there is no battery drain issue, it confirms that hotmail doesn't give u that issue
2. after No.1 setup exchange, but sync only contact and email, do not sync calendar, set it as "Push" (unless you have data plan constrain), few forummer posted that Push save better battery.
PS: There are other application like FB client for Android, Twitter, FourSquare for Android has the auto update and sync setup by default, go to respective application setting page and disable it, it helps for battery life.
Oh yes ive come across your thread and tried those options too (was using K-9 mails instead) still had pretty bad battery drain though.
I only use SNS for the pictures on my contacts, otherwise i do use the facebook app.
Thanks for your suggestions though.

Are you using any live wallpapers? I had a galaxy thing on and battery drain was terrible.
Nope, never used lived wallpapers, also have the brightness set to manual and down quite low (which im sure most of you will admit is actually still pretty bright).
Hi.
i have some questions about my battery , i want to know if im having a battery drain.
i recently installed Darky's Rom v9.3b1 (the rom doesnt matter in this situation - i tried others) and heres how my phone lasts in different situations:
when only the screen is on and everything is off(wifi bt gps ..) , it lasts 9 hours till the battery reaches 10%.
and when im playing a video using rock player and everything else is off again , it takes 7 hours to reach 10% on battery.
is this ok? i also calibrated my battery once and wiped my phone but the results didnt change.
i also tried Speedmod and Voodoo , and speedmod was better a little in battery.
i dont use live wallpapers / auto changing content.
i'll be glad to hear some advices to make my battery better ( i read all the battery threads here but still the same)
thanks in advance.
i recently installed Darky's Rom v9.3b1 (the rom doesnt matter in this situation - i tried others) and heres how my phone lasts in different situations:
You need a wipe of your phone and install a clean rom > preferably one that does not have loads of this rom drains my battery posts .
Then reset the battery stats drain the battery bump charge it and then use it for a month battery should be back to near normal .

I've read and done the most common battery calibrate for Darky's ROM but then also came across this thread:
http://darky.ficeto.com/community/i...attery-in-case-of-strange-battery-drain.1183/
I think it is interesting because when I do the common battery calibrate, I'm wiping battery stats when my battery is at 97%, 98% because of the fact that every time my phone reboots, the percentage drops.
However, with the posted thread I'll be wiping battery stats at the point where the battery is completely full which makes more sense to me.
What are your thoughts on this?
Thanks.
tnx i will test this and post the results.
wiping battery stats when my battery is at 97%, 98% because of the fact that every time my phone reboots, the percentage drops.
The drop is in effect a false reading dont bother about it .Loads of posts on the reasons why later battery charging methods have changed .
Plus some battery indicators dont like reporting 100 % .

Hmmm... Interesting point. I'm wondering for all those out there who claim they get 30 to 40 hours with moderate use if they are using stock email or 3rd party source that handles polling.
I'm using stock GMail and a Yahoo Messenger both pushing emails instantly which I'm wondering could be my issue. I've tried every recommendation for battery efficiency out there and nothing has worked. I'm draining about 6% per hour with less then moderate use.
I'm going to kill the gmail and yahoo apps to see if that makes a difference.
Will report back my useage.

bettary life totally depand on stock rom or costom rom +kernal its complicated judgement
i m on stoke xwjs5 and i found this is best bettary performanse i ever seen on i9000,
lots of fector affect betary life,
So, I removed gmail email sync and removed my yahoo mail app to install k9 email. It has a very nice interface however chewed up my battery even more so while having each email account polling every 10 minutes.
I uninstalled k9 email app and turned on gmail email sync. I also added another email account to my gmail account so that I can get push emails to both accounts.
I installed an app called battery calibrator from the market. I charged my phone to 100 percent and while charged, I ran battery calibrator. After the calibration, I rebooted my phone.
Now, my battery drops 1.5 percent every hour compared to anywhere from 6 to 10% per hour.
I don't start monitoring the battery until about 95 percent because after a full charge it drops to 98 percent in about 40 minutes. That's just how the software reads the battery usage I guess.

bettary life totally depand on stock rom or costom rom +kernal its complicated judgement
Thats it in a nutshell some roms = bad battery life as the two posters have found .## jje
I have not yet updated my Captivate to 2.2. Reading posts in regard to the update I am very bothered by a common complaint that battery life has just died. My Captivate has excellent battery life using it fairly heavily over a 1 day period. I charge it every nite. Also, my GPS is workng fine in 2.1. So am considering not updating it due to the problems I am hearing about.
Anyone else have input on battery life after the update??
I went from STOCK 2.1 to Cognition 4.1 (built on Froyo 2.2) and my battery life is about the same. My usage varies wildly from day to day, but as best as I can tell, overall battery consumption is about equal.
I wonder if the people complaining about battery life have set up their phone "post-update" with different apps or turned on "apps syncing background data"...
Battery life did reduce on 2.2 but it is obvious in my point of view. But its not too bad either.
it's about the same, i upgraded to stock 2.2, feel no difference on the battery life. moderate usage last mine for about more than 24 hrs, u should update to froyo for you to experience it.

I upgraded Stock 2.2 end of Feb and noticed a big drop in my battery life the first week. But just reading above, i did turn on "apps syncing background data" so i think that's my problem. Just turned that off so we shall see...
Let your phone go through a week or so recharging cycle before judging its battery life after a ROM flashing. You just lost all your battery stats when flash a new ROM. Your phone/OS has no clue how your battery will operate until it has time to learn or you manually calibrate it.
For what it is worth, my battery life is about the same or slightly better than leaked 2.2 ROM as well as 2.1 ROM. No big changes.
My battery has been about the same since the 2.2 upgrade. At first it felt like my battery was draining quicker but I also noticed I was playing with more phone more. The screen is the biggest power drain on the phone so just playing with menus and looking at new settings can cause a small dent.
Give it a week or two after upgrading and you'll notice it'll be about the same. Unless of course you have more accounts or programs syncing data in the background.
Why upgrade to 2.2
Thanks everyone for the input. The more I read and hear the more I am leaning toward not upgrading to 2.2. On different forums I am seeing and hearing problems with battery life and some saying about the same battery life. Also, seeing GPS not being fixed or going from working ok or good to not working so good. Right now my phone does everything I want, GPS works really good, email works fine, internet works fine, battery life is outstanding, mp3 works great, screens all are clean and to my liking, I have an easy work around for turning off 3G and one tap returning my volumes to normal after using a USSD code.
REally cannot see any advantage to upgrading and risking introducing a problem I don't need. The list of new features really does not thrill me.

2.2 ROM is a big step forward, not backward, IMO. Sure it didn't solve GPS issue but it is not making it worse either. GPS issue is purely hardware issue. If you have a good one, it doesn't matter which stock firmware you use.
I just can't see any disadvantage for upgrading (other than slightly more difficult to root or unlock, but not impossible). Battery life thing is as I mentioned above. You will see all kinds of complaints (either dain too fast or too slow) after a new firmware comes out, any firmware. You don't know what you're missing until you upgraded.
I noticed a big improvement in battery life. Sometimes with light use it will last up to four days, whereas before with 2.1 it would putter out after maybe two days.
GPS isn't fixed, but drop one of many GPS fixes in and it will get somewhat normal performance.
Wifi sleep policy
You may also want to check the Wifi sleep policy after the upgrade to Froyo. In my case, the default was "Never sleep". Changing this to "When screen turns off" improves battery life on 2.2, as it does on 2.1.
Just my $.02 worth.

I'm on stock 2.2 since the day it came out. My battery life is actually trending worse day-by-day. I did a full battery clear/reset this weekend and after 4 days I'm finding battery life is not improving at all. The degradation from stock 2.1 is significantly noticeable to me.
For the first couple of days post-update it seemed actually to be better, but got worse and worse, to where I was lucky to find the phone working 12 hours after disconnecting from the charger @ 100% ... even if I hadn't -touched- the phone during the day. My applications loaded are virtually identical to before.
I did have Background Data on, so I've just disabled it, but was this option not in 2.1? I know that Google Voice, etc, were doing background syncs in 2.1.
It can't be WiFi, as for the last 2-3 days I've kept WiFi turned off. However just for sanity I did adjust the sleep policy.
I'm wondering ... my battery woes seemed to start when I hooked up my Microcell. Could having a strong 3G signal so close to the phone actually be causing problems?

That might be your problem. I don't know. I know 2.1 doesn't work very well with microcell either.
Yep. I'm pretty convinced it is the microcell now. Phone works great with it from a call/data/signal standpoint. However after unplugging my microcell last night, charging my phone to 100%, and then letting the phone discharge normally with no microcell ... I'm now 10 hours later and have an almost full battery.
Sad, because our reception here is so spotty that we lose calls and data regularly without the microcell. My wife says her phone charge has been pretty normal, so I'm getting ready to move the cell away from my desk and see if distance helps the story.
So, as far as this thread is concerned, my results for 2.2 and battery life are great ... better than with 2.1 ... just don't use it with a microcell.
Froyao 2.2 Battery Usage Dillema
I see no significant or excess battery drain while riding the KB1 over the JF6.
Just a thought for those experiencing excessive or significant battery drain. KB1 loads some new features and new additional bloatware that loads on boot and runs as a service, process and both.
If you're familiar with poking around your system settings and understand what doesn't need to always be running in the background, or what doesn't need to load on boot, you can simply kill the process and even alter the way a certain application handles on boot.
By killing many unneeded or unwanted processes at boot time, it will significantly save you hours upon hours of battery life in the longer scheme.
Another FYI, Lithium Ion batteries have memory. You need to train or retrain the batteries memory over time in order to sustain a longer life for it.
Tips:
Don't continually through the charger on your device after minimal drainage. Let the battery run down before fully recharging it again.
When flashing to another ROM wipe your battery stats.
When flashing any new code to your device - a few forced charge deaths to purge the battery and reset the memory again prior to recharging may be a good idea...
Hope this helps...
Peace-

I've been looking everywhere and tried multiple methods to try and fix the following problem but without any success... please help!
I have a stock captivate which came with 2.1, upgraded to stock 2.2 last year, and just last week upgraded to stock 2.3.5. Never rooted or anything like that.
Up until last week, while I was still on 2.2, I had fantastic battery life, draining maybe 1% per hour when idle. After the update to 2.3.5 I'm now draining 10% per hour when idle. I've tried different watching apps to try and catch a culprit but I'm at a loss to point to anything. All the apps I'm using are unchanged from when I was on 2.2. My best guess is that it has something to do with wifi.
When I left the phone untouched on idle last night it showed 30% wifi and 25% cell standby for battery usage. My wifi sleep policy is set to never which is what I had on 2.2. I leave wifi on all the time, but I left it on all the time with 2.2 without any of these issues. I have 5 bars and am located near a cell tower so that isn't any different either.
I've tried factory reset as well as a couple cycles of draining the battery all the way down and filling it all the way up without any change. From a UI standpoint, I like the new Gingerbread update but 10% drain/hour when idle compared to a couple days when idle with Froyo makes the phone much less usable... Help!!
You could have an app that is running in the background taking up alot of ram and or CPU peformance. This can cause your battery to drain faster. Having a live wallpaper as well as apps that update in the background will also shorten your battery life.
however, there are many apps out there that monitor what the other apps on your phone are doing and will let you know if there is a rogue app taking up battery. Also, if you have the stock battery look into a new one. Its probably old by now and somewhat tired out.
I had the same battery drain issue upgrading to froyo. I ended up finding a custom GB rom and the battt drain slowed but is still faster than the stock rom. All apps have stayed the same since day 1. At this point I'm afraid to touch it again since it the wifes, and was a bit upset about the last time.

This was happening to me when I updated to GB but found it was one of the apps(No LED and Vlingo). I uninstalled and then reinstallled them and it stpped draining as fast in idle. I would also suggest getting the 1800mAh OEM battery for the Epic 4g Touch. It works great in our phones with 15 to 20% more life.
email app draining battery
I also updated few days ago to gingerbread official UCKK4 and after that my battery drains at around 5pm, whereas before it was around 11pm with froyo.
the battery log says email app is sucking it up. the email accounts are exatly the same 2 I had before: hotmail and company both configured as exchange.
Solutions?
thanks!

It seems like a lot of people are complaining of issues after the update. The most reliable solution would be backing everything up and performing a factory reset. Just be aware that when you do it, you will lose EVERYTHING on your phone that isn't already backed up somewhere else so make sure you grab your pictures, music, contacts that aren't already backed up in an email address, etc.

I did perform a factory reset after the update!
I have nothing on the phone, except few apps, which I quickly reinstalled.
The emails and contacts are on hotmail so, it wasn't a concern they get reloaded from the exchange contacts sync. music was on my external sd card.
the problem is that if I disable email, battery is fine...but, c'mon...then what's the point of a smartphone! and if I disable background check, it's also fine, but again, what's the point of a smartphone!
I am really concerned now... with this battery life is unusable.
We have two captivates in our house, mine and my wife's. For mine, I did a complete one-click flash back to 2.2 froyo and then immediately upgraded to KK4 through Kies. Overall, my battery got much better and gave me a good 4-8 hours more battery life than what I was getting. When I go to bed I'll still have 30% remaining.
Now the bad news: My wife's went the opposite. On Froyo she had better battery life than I did and she updated without flashing her phone. On GB her battery was dying in almost 4 hours, 6 hours at best. It was crazy. On Friday I took the phone, backed it up and performed a Factory Reset. For two days this gave her better battery life than 4 hours but still horrible. Maybe 8 hours total.
What I noticed:
Over the weekend I paid close attention to her phone. I noticed the 3G symbol would be displayed on the screen while she was also connected to wifi here at home. Then I noticed that her email app (not the gmail app) was the #1 use of battery, even over the display. Clearly something was wrong. Then I noticed if I opened the email app, it would result in a connection error. However, if I opened a browser or the marketplace everything worked normal.
My thought process is: the Email app is constantly trying to connect to its server and since it's unsuccessful it continues to retry non-stop draining the battery.
How I might have Fixed it:
I took her phone and put it into Airplane Mode.
Waited a couple minutes and turned on WiFi only. (Phone was still in airplane mode)
Waited a minute and then turned WiFi off.
Took phone off Airplane mode. When everything came on, the WiFi was still off since I manually turned it off while in Airplane mode.
Rebooted the phone, WiFi is still off.
Turned on WiFi after everything finished running from boot up.
Noticed that now the 3G symbol was gone when WiFi connected.
Today she unplugged her phone at 5am this morning. As of 4pm her battery has only dropped 25% (showing 75% remaining). I checked the battery usage and the Email app is back down around number 6 or 7 on the list. Not sure if that's what fixed it but the battery is a HECK of a lot better than it was before. If someone else sees these similar symptoms give it a shot and hopefully it will help.
I was having the same issue on my phone after upgrading to GB. The 3g would stay on (displayed) while I was connected to Wi-Fi. It seemed to be draining my battery. It is better after doing a cache wipe. Next, I'll be swapping modems and kernels until I find a better combo. Currently, KK4 with corn 7.06 (sio & conservative)

Interesting, I don't have wifi at home, but I also noticed at work (where I have wifi) that 3G and wifi icons were both on.
I am not sure I can reflash the phone, and I could try to reset the phone again.
I will try your "procedure" and see what happens.
1 more thing: as I said in my prev post, I use hotmail with both SSL checks, as exchange server.
additionally the other account, which now is disable (my work account), is a zimbra 7 server with again both ssl checks, and configured as exchange.
the same configuration was working on froyo.
my system is not rooted and nor modified. out of the box install.
Problem identified
I identified that the problem is the hotmail account.
I factory reset the phone again and cache wipe, then I did not install any app, apart from those which auto-update themselves.
I configured my zimbra 7 work email account (exchange activesync): waited few hours. Normal battery consumption.
Reset the phone again, then this time I setup only hotmail: battery drain.
solution:
now I am using stock email app for work account and downloaded hotmail app (seven+microsoft) which still allows me to sync contacts and calendar. It's suboptimal (i'd like to have all in 1 place), but battery consumption seems back to normal.
problem present again
Sorry, but after few days I realized the problem is still there...also using only zimbra (activesync exchange).
no solution yet. hotmail using its app seems fine, but no way to use stock email. after a while it starts again consuming > 25%
Correct me if I'm wrong...
So yeah correct me if I'm wrong, but I read somewhere that your Data connection and WIFI drain the battery quite a bit. I think I remember using something with a 2.2 ROM once, where if my screen was off, it basically shut off everything except the ability to receive calls and texts. I'm not really sure because that was months ago, but if this rings a bell to anyone, I wouldn't mind knowing too!!1!
Original poster here... After doing another factory reset, I only installed a few apps a day over the course of a week, waiting for the battery issue to reappear. Through this long process, I identified the Kayak and Facebook apps as the battery hogs. When I had everything else reinstalled except for these, I had the same or better battery power compared to Froyo. I contacted Kayak who said they were aware of the issue and just put out a fix. I think the problem was, an update for Kayak came out around the same time that I performed my upgrade (or the battery issue for Kayak was specific to Gingerbread) so it only appeared after my upgrade. Anyway, to be working better now.
Overall, I like the stock Gingerbread upgrade, especially the fact that Swype works a lot better after the upgrade.
Email battery drain
Hi all - I am beginning a search for some solutions. I just upgraded Cappy to stock GB yesterday. Did Factory Reset before and after which eliminated the Tethering Manager issue.
Battery life at home yesterday was AWESOME. I believe this is in part because the new GB defaults to a "never sleep" policy on Wifi. It literally went from 100% to 92% in 3/4 of a day, with Wifi on all the time.
Now its Monday and I'm in the office (NO WIFI HERE) and now all of a sudden "EMAIL" is the biggest user of battery. It's been draining almost 10% per HOUR this morning. I use Hotmail as my primary email and I have it set up through the ActiveSync server on the stock GB email app (not Hotmail-specific app).
What is going on? I have the Sync set to "Push" everything, which is the way it was on Froyo and it never ate battery like that. Is it something different in GB or do you think it is something to do with this "Wifi always on" policy that somehow the stock email app is always trying to connect to the MS Exchange Server through wifi but can't? (I'd think that when wifi is out of range that it would just default to 3G "pushing" which is what it did before, and again no bad battery drain before under Froyo).
Thoughts?

Cross fingers I might have solved this. Appears that having one's Hotmail and/or GMail CALENDARS synced up may cause the problem. It appeared that both of those Calendars were basically constantly re-syncing rather than waiting for a push like the email does.
I unchecked those sync boxes for both calendars and it now seems that battery drain is slower. I'll keep watching this afternoon.
Hopefully this post is helpful if others might be experiencing the same thing. I'm hoping that it is NOT the "never sleep" Wifi because from what I've read, that is actually a battery-saver when at home in constant range of Wifi. Perhaps that is why I didn't notice this Calendar-induced drain overnight because the juice was sipping at a much slower rate even if it was constantly syncing. Once I got out onto the 3G network this morning then the juice started getting gulped......
I find the fix for the GB battery drain problem

I've been looking everywhere and tried multiple methods to try and fix the following problem but without any success... please help!
I have a stock captivate which came with 2.1, upgraded to stock 2.2 last year, and just last week upgraded to stock 2.3.5. Never rooted or anything like that.
Up until last week, while I was still on 2.2, I had fantastic battery life, draining maybe 1% per hour when idle. After the update to 2.3.5 I'm now draining 10% per hour when idle. I've tried different watching apps to try and catch a culprit but I'm at a loss to point to anything. All the apps I'm using are unchanged from when I was on 2.2. My best guess is that it has something to do with wifi.
When I left the phone untouched on idle last night it showed 30% wifi and 25% cell standby for battery usage. My wifi sleep policy is set to never which is what I had on 2.2. I leave wifi on all the time, but I left it on all the time with 2.2 without any of these issues. I have 5 bars and am located near a cell tower so that isn't any different either.
I've tried factory reset as well as a couple cycles of draining the battery all the way down and filling it all the way up without any change. From a UI standpoint, I like the new Gingerbread update but 10% drain/hour when idle compared to a couple days when idle with Froyo makes the phone much less usable... Help!!

I had the same problem after the GB upgrade for my AT&T Samsung Galaxy Captivate phone. After I read this forum, I figure the Outlook email setup would be the problem. I did the following changes and corrected the problem completely:
1. go to "settings"
2. go to "account and sync"
3. click on the Outlook email account under the "manage accounts" section
4. click on "Account settings" under "General settings" section
5. click "sync schedule"
6. change "peak schedule" to "15 minutes"
7. change "off-peak schedule" to "15 minutes"
8. click "save"
9. Done.
"Push" setting in "sync schedule" selection is the culprit causes the battery drain problem.
Good luck
Hello all,
Today i want to share something about a battery drain that i used to have since 4.3 update. Since i updated my phone phone to 4.3, i was having a irregular drain in my battery. It drained about 1% or 2% per hour with wifi and data off. After much research, i found the killer of my battery. First of all, i searched about a reason for my battery draining even in iddle state. For this, we must read about wakelocks first (READ HERE). Please remember to give him thanks for his awesome thread.
First thing, i reinstalled a 4.3 stock based with full wipe. After all apps were installed, the battery seemed to be ok.
After reading about these wakelocks (i recommend BetterBatteryStats for the following), i found out some interesting ones, like secril_fd_interface (fast dormancy related). For who that doesnt know about Fast dormancy, it is a service that is intended to save your smartphone's battery when it is in a mobile data. But for this service to work, it requires the network provider to have that service running too, if the network doesnt have it, your phone will have various wakelocks trying to have a response from network. In my case, my provider does not have this, so i disabled it with this app (works for our model too).
After that, i configured my two email accounts (hotmail and my work's mail, wich is a mycrosoft exchange account) and left the phone with wifi on while i slept. For my surprise, my phone started to drain battery like crazy, it drained 20% overnight with just wifi on. When i opened BetterBatteryStats, the only wakelocks that caugh my attention was the exchange services (more than 200 wakelocks with sync configured to 1h and syncing just 3 days of mails). After this, i knew that if i remove my email accounts, the problem will be gone, but i need those for work.
I read somewhere that the exchange app does not have the ability to sync some folders on our mail (drafts for example), so i removed everything inside drafts and another unused folders, but no lucky.
My accounts were configured to sync 3 days of mails in an interval of 1 hour, so why in hell was more than 200 wakelocks at 1400Mhz of CPU? So i tested one last thing in email app. For my surprise, my battery problem was gone and 80% of email related wakelocks too.
Here is what i did:
1. Openned email app, go to settings.
2. Go to account settings and tapped on the account
3. Rolled down and tap in more settings
4. Tap on Folder sync settings
5. Tapped over avery folder that appeared and changed the sync schedule to manual and period to sync mail to 1 day
6. Did that on all my accounts, now my problem was gone. The battery life increased not only my phone is iddle, but when i'm using it too.
I hope someone else will be helped with this. Any problems to understand the post, feel free to ask.
But this solution isn't actually a solution?
Your battery drain was related to wrong configuration of mail clients. In age of great power menagers (I won't be making advertising now) that's not a problem at all. And you are talking about basic configuration Sorry dude.
The bug on 4.3 is related to "mdm_hsic_pm0" going crazy randomly and preventing from deepsleep and there is no solution for it atm since we are not sure about source of it.

This was not a wrong configuration made by me. Everyone i know that don't have a samsung phone doesnt have this problem with exhange. The other thing, i have these wakelocks (mdm_hsic_pm0) too but my phone enters in deep sleep normally. If you read the tittle of the thread you will know that i am not solving ALL battery issues, but those who MAY have an exchange services excessive drain like i was having. If you have nothing to add, then please don't say crap.
No offence. I just want to suggest that topic name is not precise imho. Especially when we are encountering here just fast dormancy.

I didn't see a motive why people could misunderstood the thread by reading that tittle, but i edited to be a bit more clear
