[Q] Battery Life on KE2 - Galaxy S II Q&A, Help & Troubleshooting

The S2 is essentially unusable right now, with the battery drain problem. I have tried everything described on these forums. reflashed the phone a dozen times, reset and tried every thing in the book. Only thing left is reflashing backwards to KE2.
Does that offer a less of a battery drain, than say the KE7? Mine is at such a bad spot right now, its not funny. Running stock KE7 with 3 apps installed, it's lost 30 percent in 3 hours. or there abouts?

Did u try to turn the wifi off ? I recommend you to try out the Juice Defender app which help improve the battery by controlling wiring and other connectivity. It will auto turn off wifi when screen off.

Yea i did. Bought the ultimate version of the app. Not much change.

How long were u playing with it in those 3 hours? What's your screen on time?

i Have KE7 installed. Its rooted and i am using Antek App Manager (free) to freeze some of the samsung crap plus using Android Assistant to clear cache and close programs etc. My battery is pretty good. last night, on a full charge, found out in the morning it used only around 7% of battery. During the day the battery usage had been good too. Wirless is on and background sync enabled, battery on 66%

I had KE7 installed from the off. Battery life has been improving for me (Only had the phone about 10 days)
I keep things down to a minimum (no Wifi, bluetooth, background sync).
I managed to get nearly 3 and a half days out of my last charge. This is with occasional texts, emails checks, phone calls and Google reader updates. I use launcher pro and have set the weather widget to update every 3 hours.
The battery on my Orance San Francisco hardly used to last 2 days with similar usage.
With the screen size & processor power, I for one am very happy with the battery life of my SG2.

None. I was snoozing. The handset had been taken off the charger, email account configured and i had taken a call. Fell asleep after that. Screen on time was 78 percent. (Only apps open were a gmail one, 3 browser windows and titanium)

Great life here
Just to add a counterpoint, I'm running stock unrooted KE2 and am having incredibly great battery life. No frozen apps or battery management apps, other than the stock settings that kick in after 50%.
I recently forgot to charge overnight, and still had >40% battery left after around 36 hours of moderate use.
This is with auto screen brightness, WiFi always on, no syncing except for gmail/contacts/calendar (With a fairly high degree of gmail traffic).
During that time I played Angry Birds, used GPS navigation, send numerous texts, emails, and phone calls. Recorded about 10 minutes of 720p video, took a bunch of photos, and browsed the web periodically.

I'd love the OP to send it back, and see if his new one had the same issue. Maybe it's his 3G, or maybe a just a bad unit? You paid alot of money, something this serious send it back.

There is a huge gap in the middle where you didn't turn on the screen, for like 16 or 18 hours (except once).... Be honest, while sleeping, do you hibernate? hehehe.

Lol. Actually I'm pretty sure the screen would have been on multiple times during that period, just not for extended periods of time. Perhaps they just didn't warrant an entire pixel?

juice defender doubled my batt life. i also froze some sammy apps with titanium.
have gone from 12 hours of batt life, (which i could live with, that pretty much what my n900 did) to nearly 2 days with moderate usage..

Wow... I would love to have that battery life...
Is it true that after some time of use of the phone the battery improves a bit? (I read it somewhere, but I don't remember where nor if they mention what was the reason for that)

Planning to do that today. Got just a couple of days left on return policy. If not.. well i am stuck. I love the phone. I want it to work... but 5-7 hours is just nonsense. I hope 2.34 ships soon and sorts out the mysterious drain.

Yep KE2 has much better battery life than KE7. For me anyway. I can get a full day's use out of one charge with moderate use and screen brightness set to 50%.
I have also frozen all the bloat. In idle with email set to push the phone uses about 2% an hour. Which is not bad in my books.

Batt Problem...Please Help

I know this has probably been asked hundreds of times and I have searched up and down the forums but have found no fix for my battery problem.
I always have my battery at the dimmest level. Mostly only text, the occasional 5 min phone call and web browse here and there. Yet when i look into the battery use the display is always at atleast 96% ive never seen it less than that. But i kno that it has to be something other than just the display though.
I stoped using beautiful widgets, and froze media hub (i read that it eats battery in the bg) recently ive been monotoring my system through system panel.
As of now system panel tells me that System Processes is at 5.7% and system at 2.6% The next highest thing is Swype at 0.4% and android.process.acore at 0.2% the rest of the things are at 0.0%
I was thinking that it might be the battery or just the phone itself...
Edit: im sorry idk why the app didnt post all my post <=(

Having your screen use that much (as a percent) isn't necessarily a bad thing. It means that everything else is using minimal power. You also shouldn't be checking your stats for useful info within moments of turning it on. Give it a whole day of use and check again. Your screen will have used less % after a day but it is totally normal for it to be the largest user of power.
So then what could be causing the battery drain?

How much drain?
You should expect to get 4-5 hours of use from your Vibrant. Total time could range from four hours to several days, which is what you hear people saying in most battery threads. What they often don't state is how much time the phone is actually in use and whether you get 5 hours or 24 hours before you hit 0% battery you probably are using the phone (screen on for anything, or screen off while listening to music or talking.) for 4-5 hours.
So is your phone getting less use then that? If so then you may have some other issue.
http://forum.xda-developers.com/showthread.php?t=848207
The links are very informative
Of actual use, not just standy by I get just about 4 hours. Usually under 4.
And that link looks pretty interesting

Fast Battery Drain
Bad News Everyone!
I have spent the last 3 days searching here and other forums trying to find out why my battery has been horrible. My battery goes to around 30% after only 3 or 4 hours of very slight use (2 or 3 texts and checking email once).
I have done two complete battery drain to full charge with the phone off the past two days to try and get a better reading.
The history of the drain, at the end of November I rooted and installed RyanZA OCLF, rooted, and lag fixed, no issues. Installed the basics of rooted (busybox, superuser) and SetCPU.
SetCPU presented problems with not coming out of sleep and freezing after reboots. The battery would give about 6 hours of moderate use. I played around with settings, but ultimately removed it and when I did my battery was lasting 3 hours longer with moderate use, facebook, twitter, browser, 20-30 mins of gaming. From 12:00 pm (leaving work) to 9:00 at night (leaving school) with 35-40% left before I got home.
About 4 days ago, my battery was draining very quickly. Wake up, unplug phone at fully charged, get ready for work, grab phone to leave for work and I am down to 90% after only 20 minutes of standby. When it use to have it around 96% by the time I got to work, about an hour with light use. Seeing this problem I went back and looked at updates and apps that I had. The only thing I could think was Launcher Pro, but no one else has reported battery drain issues and it wasnt showing in Battery Info.
In my attempts, I have done the following.
Went from 7 to 3 screens (one widget per screen)
Removed apps and bloatware with Titanium Backup
Doubled checked my account syncs, Facebook once a day, no twitter sync,
Screen brightness at ZERO
2 Battery Resets (fully drained to recharge phone off)
Installed Watchdog to find any heavy mem/cpu users, (none found)
And a crap-load of googling, forum searching (here and cyanogen forums), and I am still getting horrible battery life.
Today for example: Phone completey charged 10:30 am with only 3 texts sent and I am currently at 28% at 3:15. 5 hours of stand-by should not have drained that much battery. No GPS on.
If you have any ideas of what it could be, at this point I have alread bought a new battery, I would love to hear back.
edit: I am running stock rom 2.1-update1
I used to have poor battery life as well on stock 2.1 rom until i flashed the leaked jk6 update. Im now averaging about 25 hrs per charge with my phone pretty much always in use whether its calls, texting, music, gaming, web, movies ect...
Not to mention i also get 3g in places i havent before and faster DLs, less lag... This rom is awesome, i suggest giving it a try..
Sent from my SGH-T959 using XDA App
dubbz106, thanks for the advice. I have not had a huge desire to flash a new rom because my phone had performed pretty good. But with my G1 I was keeping it alive through cyanogenmods.
I have been moving closer to flashing and this new battery issue my push me to do it.
Can you link the thread for the rom?

5 hrs on batteryand I'm @ 98%

Given the recent run of battery posts, i thought i would join in. Yes you read it correctly; 98% after 5 hrs on battery. Thats with an up-time of 8:20, and an awake time of 1:51. During that time i checked and replied to a couple of emails(opened a photo attached) looked at pics in the gallery, and watched a 30 second video w/max volume three times. Also checked the weather several times to update the 5-day forecast.
So whats the secret? Dont open up any of the other screens after you reboot. Or, you can remove whatever you have on there and have only one active screen.
Heres the proof ( sorry about the crappy pic, all i had was my old Hero)
How do you do it can you explain a little better
Sent from my PG86100 using XDA App
Well, I don't have a picture, but my battery is down 2 bars on the screen you are showing...so roughly 80% I guess. I have up time showing 39:17:xx and awake time of 12:51:xx. I've looked at some pictures of my cat several times (had to put him to sleep yesterday due to a degenerative disc disease that finally damaged his spinal cord to where he couldn't walk anymore ) I did a lot of texting, e-mailing, some web surfing, and updating some programs from the market. I also talked on the phone for about an hour.
What did I do for this? Well, the only account sync I have is GMail, all the other crap is turned off. I have the LCD brightness locked at about 20% (auto brightness unchecked), I use WiFi whenever possible since 3G sucks the battery, and the only widget I have running is the HTC Sense weather/clock thing. It is set to update every 4 hours. Otherwise pretty basic stuff.
Uptime and awake time don't mean anything in regards to your claim. That just means, since you last rebooted your phone has been up for 8 hrs 20 min, etc. What you have to show to backup your claim is the time since unplugged...

Well, I don't really have to prove anything to you. We are not in court and I am not on trial. However, I can tell you I wake up every morning at 7:30 and unplug my phone which means, at the very least, the awake time is accurate. I didn't realize up time was only since last reboot. But still, sitting at 8/10 bars at 13 hours. If you don't believe it, then don't.

OK, so its was on battery for 5 hours and I unplugged it at that time. Im not trying to brag, cause frankly the battery was pretty crappy for the first week. I believe the stand-by time on this phone is awesome, Im more concerned about how fast the battery drains once you start using it.

When you reboot your phone, the only active screen is the home screen. If you long-press the Home button, you will see the other six screens blank. I left the other screens the way they came from the factory and found out that if you even look at them once, they seem to remain active even if they are not being updated.
I was charging my phone before I went to bed, and waking up with 95% (yes I minimized all the background updates). Then I would drive to work with BT on and it would go to 93%. 12 hours later, after two text messages and two voice mails, Im at 70%. Sure my up time was 19 hrs, but my awake time was 40 minutes max. So basically you need to keep everything but the essentials off your screens. This is my experience, as im sure there are people out there on 4G 8 hrs a day who come home with 50%+ on their phone.
Can I put apps on those screens so basically no widgets on any screen but the home

You don't have GPS enabled. That's cheating.
3G (or WiFI, 4G enabled) GPS, auto sync, backlighting, widgets, exchange, twitter, facebook, live wallpaper, all the reasons we bought the phone?! Those should be running at all times. (Otherwise, what exactly is the point? Srsly?)
If the battery life is still 3 hours then I am expecting a phone that hasn't and won't be built for 20 years.

I think we use our phones very differently. I like those features but I don't have them on all the time. I use the GPS when I need to use a GPS. I look at FB or Twitter when I have time to look at them. Live wallpaper, while cute, doesn't do much for me. Exchange and Gmail push is about all I use regularly.

I get about the same when I'm working a 10-14. That's with checking exchange email, background sync and data on, sending texts on a normal basis, brightness about 30-40%, checking fb, etc etc. Battery doesn't drain much at all for me while it's sleeping which is great when I'm working these shifts and don't care to bring a charger.
Using GPS with location on and Sprint Navigation will drain that beast though, but that's expected.

Damn your finely worded post. Now I feel the sudden urge to re-evaluate my obsession with live wallpapers so I don't feel like a lame kid that likes something "cute"

I had a epic 4g with extended battery 3500 mah and I would constantly use the phone even while at work.. At the end of the day my battery would be at 50%. On my evo 3d I use the phone even more now because its new and my battery would still be 50 % at the end of the day.
Fairly impressed
Doesnt the GPS only draw power if an app is actually using it at the time? So does it matter if you leave it on
Im pretty sure that if you leave your GPS on it will be put into "stand-by" mode, which in effect draws power. I could be wrong tho

that aint proof at all
use a program like battery status, that'll actually tell us how long its been since it was off the charger
but even from this, shows your phone doing a lot of sleeping
we'd be more impressed with a lot of battery left after actually USING the phone
I shut everything off that im not using. Only time my battery life sucks is when Im at work and get very low signal. That drains the crap out of the battery.
Plus I use Juice Defender, seems to provide some improvement.
After being unplugged and having used it as I described, after 20 hours I still had 68% of my battery charge. I don't have juice defender, but I made the adjustments I mentioned and the one I forgot to mention is I also turned off location services.
So far I am pretty happy with the battery life, but I also remember with the Epic I had amazing battery life for a month or so and then it was more like what is "average" for that phone. I'm no scientist, but I would guess that brand new lithium batteries do a little better and then when the chemicals start breaking down you lose that "little extra."
Sorry, I guess I should have included two pics. I do have battery status and it showed 5:05 since off the charger. I chose to post the other pic since I thought it meant more in terms of use. Sure it doesn't tell you how I was using it, just that it want sleeping for half of that time. Im not trying to impress anyone, i just thought it was a huge improvement from the past week where 5 hours off charger showed 70% battery left with only 40 minutes of up time (which resulted form a couple of VM and texts). So my point was along the lines of; more use, but huge improvement in battery consumption.

20hours, and almost 70% left?
i say super BS
because you know at that rate you can go almost 3 days with no charge right?
i know the evo 3d battery has bout 150 more mah then the 4G, but c'mon son

Battery gets literally 4 hours before it's dead

I ,am on it a lot, between GPS and general usage, ,but this still seems like too fast to drain compared to what others here have said. I had this problem with my Atrix too, maybe i am just destined for bad luck with battery life
Do you use anything like juice defender. This app literly doubled my battery life!

Apps like that only increase standby battery life. Everything else is very minimal.
And I'm not happy with the battery life either. My phone is plugged in right now and the battery is actually going down as I use it.

I pull mine off the charger at 7:00 and at 3pm or so it's down to 85%, I'll put it on the charger at work until I leave around 5-6pm (mainly because I'm used to having to do this on my previous phone) and at night if I'm not using it constantly it's around 70-75% when I plug it in at bed time.
I suspect anyone getting that bad of battery life must be using it constantly, ie: Playing games, browsing, trolling facebook, etc.. Even in the "new toy" stage I'm getting great battery life.
FYI I don't have LTE, but do generally have good 4G.
You honestly can't use any phone on GPS without external power and expect that you're not going to discharge quickly. Assuming that you are running a car charger during GPS and just didn't say so, search the i-717 threads, since the topic has been well vetted on what chargers are more effective,etc. There are definite differences.

The fact that there are people out there that get really good battery life means the problem is you and not the phone. If you refresh facebook every minute of course your battery life will be crappy. apps like juicedefender are just marketing crap. as long as there are no running apps in the background that eat your battery, you do not need any juicedefender or tasker. also setting screen-off behavior to conservative on set cpu helps improve battery life.
When I first got my i717 and was using it on the stock rom I had pretty terrible battery life. I take it off the charger at 5:00am and had decent battery life (around 5 to 7 hours without GPS) but I use my phone a lot for internet/email. I think your battery life is completely normal given your usage.
Most people get about 5hrs screen on time. Total on battery ranges up to about 24hrs, but only if the screen is off at least 19 of them.

i can get about 3 or so
5 hours of screen time AND 19hours standby sounds incredible
would sure like to see screen shot as well
and def dont think 5 hours is any type of avg
I had GPS running on my phone for 4 hours today, had blue tooth on half the time without knowing it, sending text messages, making two 5 min phone calls, checking maps, checking FML and reading a book for about an hour and drained down to about 70% and I have the brightness set at auto. I would exchange it for a new battery.
On average with several texts per hour, several 5-10 min phone calls, taking a few pics and uploading them to picasa, checking facebook, updating status and checking emails I can pull off the charger at 630am and still have 50% battery (at least) by 630pm.
I do have the juicedefender (which isn't crap, it turns off signal after so long so you aren't trolling for signals when you aren't on the phone).

On average with several texts per hour, several 5-10 min phone calls, taking a few pics and uploading them to picasa, checking facebook, updating status and checking emails I can pull off the charger at 630am and still have 50% battery (at least) by 630pm.
I do have the juicedefender (which isn't crap, it turns off signal after so long so you aren't trolling for signals when you aren't on the phone).

and whats your screen on time for that 12 hour 6am-6pm with 50% still left please?
Just buy a second battery and throw it in at noon. No biggie.

Was thinking of doing that since they're so cheap but thanks to juice defense I don't really have that issue no more.

I had a ss of my buddies yesterday, but can't restore mms lol. There are plenty of other ss in the note section. He was at 22+ hrs with about 4:30 of screen on and some % remaining. I have to charge around 7-9 everynight at 4-4:30 hrs screen on, but my use is pretty heavy. I sync 4 gmail accounts, a separate GV, 3 calendars, and several apps.
If yours is much worse than that, you likely have a few troublesome apps or are playing games. First, after a full charge, reset cpuspy timers, lock it, and set it down for a few hours (I know, impossible). Then check to see that your CPU has been in deep sleep about 95% of the time. If not, use better battery stats to see what has been request wakelocks. Not only the most total time, but the total number. Any app that looks outrageous, freeze it or uninstall it. For system processes that look troublesome, Google. You can often find simple tricks online that will tell you what's causing them to go crazy. Beyond that, turn off syncing of anything that isn't needed or doesn't matter (like Facebook), and uninstall stuff you never use.
Another slight help is the brightness widget (don't use the actual widget, just put the app on your homescreen, it works the same) or dimmer in market as they can both set the brightness to a value of 10 (Samsung lowest stock is 20), and even if you can't tell the difference, it helps. Jkay settings in saurom can set the auto brightness profile slightly darker than stock. Umm, and the obvious, use less Widgets, longer sync intervals, processor scaling and speed profiles, and buy a couple rapid chargers, wall and auto.
A couple things to note after seeing a few of these posts...
BT can be on, but without it searching, connected, or listening it's not active.
GPS isn't active unless its in use aand you see the icon in the notification bar. That being said, fb, websites, and many other apps that request location will activate it.

YOU MUST CALIBERATE THE BATTERY!! I have no issues I use my phone heavy all day and get 15 hours and I still have 20% left. All you have to do is
1) Charge you phone until it says "charged"
2)Leave phone plugged in and power off and let it charge until the battery meter literally says "100" (screen will sleep so you can check with volume rocker to light screen)
3) power on phone and let boot and than power off and wait till you see 100% again
4) now keep doin this and you will notice it will start displaying "100%" faster and faster usually takes 6-7 times cycling like this
5) After you do this download Battery Caliberation (root required) app from market and hit the caliberate button and boom your good to go
I do this on every android phone I own when I flash a new rom or purchase a fresh one. Everyone should do this everytime you flash a new rom and I can CONFIRM significant battery longevity on all my android phones I have done this with
You only have to do it once so just get it out the way and you'll get through a whole dayand have some juice to play with.
I get 15+ hours and do not any battery juice defender apps

The fact that there are people out there that get really good battery life means the problem is you and not the phone. If you refresh facebook every minute of course your battery life will be crappy. apps like juicedefender are just marketing crap. as long as there are no running apps in the background that eat your battery, you do not need any juicedefender or tasker. also setting screen-off behavior to conservative on set cpu helps improve battery life.

Just to be clear here, Tasker has nothing to do with battery life. It doesn't hurt it, nor "help" it. However, you certainly could write tasks/contexts that would decrease battery life, and there are a few scripts out there which do silly stuff like autokilling, etc... But if we're talking "battery savings", Tasker and JD do not go in the same category.
IMO JD is only useful if you're frequently in an area with no signal, like you work in a basement or deep inside of a solidly constructed building. Since you mentioned Tasker, in this context it does help me a bit on battery because my wifi turns off when I leave the house, but that's also something JD can help with. If you don't have a wifi connection it'll turn off wifi (and I believe turn it back on periodically to see if there's one available?) I don't use JD, so can't speak too much for it.

exactly how much screen on time do you have by the time its at 85% ? because i mean, it can go on standy for days with nothing on

Hour? Hour and a half? I'm working during that period. I usually hit news sites and G+ when I'm first at my desk in the morning, so that's 30 minutes or so off and on looking at it, then perhaps an hour over the rest of the day, sometimes more at lunch.
I'll look closer today and post back.

Battery Life Span

Am envious to those who managed to use their phone for more than a day. I bought this phone for about 2 weeks now and have done the normal full charge for 8 hours on the first time. Since then, I have fully charged twice and let the battery gone flat once. I have flashed Neutrino rom and currently Latveyit rom, and the battery last best 12 hours so far.
I charged the phone to 94% at about 7pm and just made two calls and two text messages. I did a navigation on maps for about 15mins max. By about 11pm, battery is at 57%, I play some games for about 10mins and went to bed, in the morning it's about 35%. I realise that the first 50% really goes fast and after that it's pretty decent until less than 20% and it drains fast again. Background application I have are the normal chat programs, whatsapp, viber, kakaotalk, skype and ebuddy. I have waze running in the background although I think it shuts off after 15mins. I have a mix of wifi and 3g usage, usually on wifi though. Is this normal?
edit: I also have Lookout antivirus running
All your chat programs running in the back ground prevent your device to sleep correctly, they wake it up every time they check if there is a new message.
Try to keep only the apps you use and try for each app to increase the check delay or disable it.
The antivirus does help.
2 weeks is a bit early to make a comment about the battery.
Download Battericalibration from the market and use it every shift rom change.
Read about topic on the forum but not become a maniac in "battery life".
If the screen stays lit for 5-7 hours the battery will be empty in like 7-8 hours. If you only speak 1 hour at it the battery will be empty in 3 days.
All depends on how you use it!
Sorry for bad english.

I thought that the chat programs will only cause problems if there are frequent messages since they're base on push?
2 weeks is early? How does that affect the battery's performance? I thought when it's new, it's most optimum and slowly degrades through time? The screen was off most of the time unless I was doing anything I mentioned or just checking the time which is just on, check then off. I don't think I am paranoid over the battery life, just curious how to get it over a day.

In my opinion the battery reaches her max in 3-4 weeks.
Download the app from the market and use it after every rom change.
I didn't called you paranoic, just that you mustn't be so worried.
My recomandation for a longer battery life is CM7.
GOOD DAY!
Read forum for more details.

You might try 1Ghz faux kernels as well. They seemed to have helped my battery life considerably.
Chek out what apps you have running in the background and be sure you set youre network yourself (my phone was always changing from 2g to 3g and after i selected the network myself it gave me a 1day + boost .
And you shoud know that the litium polimer batteryes are affected by cold temperatures.
I wish you luck!
I did use cm7 (neutrino) and got about the same battery life span as the current rom (laytveyit), and am currently on the faux 1ghz kernel. Anyway, I will see how it performance in the weeks to come and hopefully the newer version of the rom will improve it. I thought cold temperature helps preserve the battery's life span?
EDIT: Thanks for all the advice!

Lol all those chats are you problem imo
The "standard" apps used to figure out what's eating your batteries are:
BetterBatteryStats: for wakelocks
CpuSpy: to tell if you phone is going into deep sleep or not
Built in Battery Usage: to see a pretty graph and tell what's using the most juice
SystemTuner: I just recently started playing with this, lots of information.
Look up BetterBatteryStats here up XDA. There's plenty of threads on how to use it. Look up wakelocks.

(Xperia Go) Battery Life

Hi I'm looking for a discussion rather than a Q so I chose this section.
I'm looking to chat with Go users about the battery life. How long does your battery last and what do you use it for? I notice that it
has a comparatively small battery but this doesn't always mean low battery - and I notice this phone IS being officially updated to Jelly Bean. I think the lower resolution screen helps keep the CPU and battery relaxed perhaps? What's your usage like?
Per Day Usage
Phone calls
Music
Internet browsing
I'm using the Sola and I hate the battery, I have to charge it 1-2 times per day. I use it for 1 hour of browsing, 1 hour of music, 5 minutes of calls, lighting texting - then it dies, I hate it. I'm considering the Go or J. The J has poor CPU/RAM but far bigger battery vs the Go.

The GO has a *****n nice battery life I'm using a Sola and get round 16hours. My friend got a GO and his battery was after 9 hours from 100 on 80%!!
After 9 hours, your friend's Go went from 100 to 80%? That's not bad at all! Does he/she leave the internet on? That seems to be a huge battery killer but I need it. If the Go could last 2 days I'd buy it now...
I bought my XGO two weeks ago, and below is my battery life and its usage (sorry no screenshots)
Battery Life:
100% to 15% lasted around 45-50 hours
2 to 3 hours screen on time
Usage:
Exchange push sync (email, calendar)
Gmail push sync (email, calendar, contact)
Outlook.com sync every 1 hour (email, calendar, contact)
No Social Network (Facebook, Twitter, etc) sync
light web browsing of 15 minutes daily
Power Saver implemented:
Installed BitDefender PowerTuneup (disable all network connectivity from 1 - 6am daily, except only connected to basic phone network)
Restricted all background 3G data except for Exchange, and Google native services
Location, GPS, Bluetooth turned off 99.5% of time.
Screen Auto 55%
Battery life is almost the same as my Galaxy Nexus, but my Galaxy Nexus can never get more than 2 hours screen on time even with 2000mAh battery, I guess maybe the screen used up too much power... Battery life for Go is pretty good in my opinion, would be super if it comes with 1600-1700 mAh battery...

Yes he did The whole day, his mobile Internet is activated and he has a screen on time of round 75%!!
I get about 4-5 hours nonstop browsing with brightness at about 30%, wifi and autosync on.
If wifi is off, I lose 2-3% while I sleep. That's about 7-8 hrs of sleep.
I keep data on and forced 3g during work. Signal is poor at my desk so with constant use I end up with about 30-40% after 7 hours if I didn't bring my charger.
Battery mileage really depends on how it's used and what's installed and what's running and how bright the screen is.
The bottom line is that this phone lasts one work day with me without having to charge.

My experience from Go's battery is that if you do not have 3G on is good. Otherwise it is draining too fast. I get 1-2 days battery life depending on the use. Usage is mainly phone calls and texting and a bit of browsing and checking fora through tapatalk or xda apps. For forum reading I use 2g/edge so to not drain my battery. Brightness is at auto with 100% max level. In general I don't think its battery cab endure a whole day of heavy use.. Screen usually drains 65-70% of battery according to statistics.

Xperia GO Battery Life
I got this phone two weeks ago after having a water ingress failure on my Motorola Defy.. what a shame, but now I'm happy. This ST27a is a great phone, I am not a phone movie watcher or gamer, so CPU and RAM are more than adequate for myself. Great look, light weight, perfect size AND waterproof (angels singing)... I ordered it unlocked and it came with ICS pre-loaded (4.0.4), at first it was such a huge disappointment as for the battery life, it was draining very very quickly almost needing two charges at day, there was a system update available but I was lazy enough to not install the Sony thing on my PC, then I finally got the weekend time and updated it (to the 6.1.1.B.1.10, KERNEL VERSION 3.0.8+) IT SOLVED MY BATTERY ISSUES!!!
The phone has a more than sufficient battery life, I do surf web every time during the day, have updates every 30 minutes for Gmail, Facebook, weather, news, everything, and it lasts from 8.00am at 100% to next 11.00am to 14% (which the preset low batt alarm sounds). Only thing I do is switch data off during night that's it. Screen brightness while in the office is at minimum but you can easily read it very clearly. I do take a lot of pictures for my work and some videos and still get that battery life. The phone is OK, just take care of which software version you have installed. I am sure that if I would turn the data off and activate it only while the screen is on, the batt would last at least two days (I will make this test and see what happens).... cheers.

With data, bluetooth and wifi off, I only lose about 1-2% overnight.
With Data on, this thing drains about 1% every 2 minute or so.
