[Galaxy S II General] prophet42:
Hey, no worries. The more information the better when buying, that's for sure.

Right what I did was this, I'll add phone 1 and phone 2 for comparison:

On home screen:

Phone 1: Had beautiful widgets displaying clock/weather and battery life. Was set to update every hour.

Phone 2: Use simi clock widget instead to display time, weather and battery again. Update interval for weather set to 1 hour.

Phone 1: No other widgets changed from stock which update or anything.

Phone 2: Also have accuweather weather widget running, with 3 locations all updating every 3 hours.

Accuweather is a stock widget that comes bundled with the device, but not made by Samsung if you get me.

Also I had other apps updating on the phone:

Phone 1: Social hub had Facebook, Twitter, and Gmail all set to update every 3 hours (that's the default. Oddly you don't configure this in social hub, you have to go into the phone android settings, and do it in "accounts and sync".

ALso had Facebook for android app running (set to push updates as notifcations happened i.e. all the time), also had whatsapp and LiveProfile running in the background updating the same way.

Phone 2: Am not using social hub at all.

Gmail is syncing on the phone (i.e. the app itself), which again will just pick up mails from google as they arrive.

Facebook for android - again just pushing notifications to the phone as they happen.

LiveProfile - the same.

That's the only changes I've made, and I'm definatley noticing a difference.

For example when I say the phone (phone 2) dropped by 10% in 4 hours, I was using it all the time in what I call moderate usage. I.e. no youtube, video, or sound playing.

I was texting all the time, using live profile to message people throughout, installing apps from the market place such as all the angry birds (played 5 levels of angry birds rio in this time), go keyboard, pulse news reader, bbc news app, runkeeper, logmein, wapedia, swiftkey, imdb, logmein etc. all of which set to update manually (i.e. I don't keep news things like bbcnews or pulse updating in the background - I just update them as I open them).

I noticed when looking at the battery stats that the screen was still accounting for 63% of power drain, so I've changed the brightness down to 0% as even on this level it's more than bright enough to see fine (unless you're outside).

So far, so good.

If I don't touch the phone, I find with sync active on 3G it's dropping by on average 3% an hour. 5% if I play a bit, go online to read the news etc. via bbc and browse a few pages. If you want anymore info, let me know and I'll do some tests today or tomorrow for you if you like.

Heavy Useage

My S II is now on day 11 of charge-cycles. I did a quick test of what I would call typical(?) "Heavy Usage":

http://domarmstrong.blogspot.com/2011/05/galaxy-s-2-ii-battery-life-heavy-useage.html
[Galaxy S II General] vimto25:
wow if thats correct then what a device!!!, dont understand what some are saying that its not very good.

Do you use social Hub?

also can you tell me if you used the device straight out the box and waited till it discharged or charged it up first till battery full

thanks
[Galaxy S II General] prophet42:
Good work. That's definitely heavy usage alright. Either way that's a hell of a lot better than my old HTC HD2 would get.
[Galaxy S II General] NIK516:
More info on your home screen, widgets, wifi, gps , whats on whats off? pleaseee :)
[Galaxy S II General] arii1986:
Compared to the my old Galaxy S the battery is far better. I'm not constantly looking for ways to conserve the juice with the S II.

Screen brightness on max

Constantly connected to wi-fi

Heavy Internet usage

Robo Defense (1-2 hours play time) this game killed the battery on the first Galaxy

Youtube

Occasional video/photo taking

Background data on, syncing FB and Gmail

I get a whole day with all of that plus I have a little bit extra. If I did all that with my old Galaxy I would be charging within five hours.

However: I did have Darky's Gingerbread Rom installed (9.5). Heard that this rom had bad battery drain but tbh my battery pretty bad before I flashed it anyway.
[Galaxy S II General] troed:
Tx a LOT, buddy ! :D:D:D

THAT info helps me a lot when I start with SGSII from the very first beginning.

Tx
[Galaxy S II General] Dombledore:
Let's all be honest now: battery life on any smart phone is terrible. Really I want the benchmark of any phone to be at least a week, not at least a day! The SGS2 seems to be a step in the right direction though!

Yes I use social hub. I couldn't wait to use it, so I drained the battery out of the box and left it for a long charge. Lithium Ion batteries aren't as fussy about how you charge them: but typically (I think) the last 10-20% stage of a charge (the "trickle charge" takes about the same as the first 80% and this can be the most important. Best thing to do is just use the adaptor Samsung Provided and leave it plugged in (turned off) until it starts beeping at you.

You should be able to see in the blue-bars below when WiFi is turned on (constantly for the second 2/3). GPS was only on for a short amount of time while I was using MyTracks to test the GPS (with great success).

As mentionned in the post but not that accurately: Widgets were weather (the accuweather one that comes loaded as default), stock market (yahoo?) + the email one that comes pre-loaded on the home screen.

I've been really impressed with the battery life.

Are we not also forgetting that this has one of the largest screens ever seen in a smartphone, with not only the most powerful CPU, but TWO cores? Have you seen how small the battery is?!

I'm surprised it lasts more than 30 minutes! Technology really is a wonder!
[Galaxy S II General] troed:
............. and if really no current outlet is in sight and You heavily use it there are always solutions like:

http://www.swisssolarcharger.com/dynapage.asp?mpage=POWER-TANKS

just ordered the XL-version .......... :D nice to have such on a 12 hour flight pressing the max out of the SGSII .............

BTW: there will be also extender-akkus available as phone-cover-shells with time for SGSII ............................
[Galaxy S II General] Shaady:
I have taken facebook from the social hub, and even that seems to have made a massive difference.

I have had the wi-fi on all day, and this morning connected it to the car, so the bluetooth has been on all the time too. Been browsing the market on wi-fi, installed a few apps, played a couple of games for a about 20mins in total, and synced around 200 photos to it via wi-fi, and im on 72% battery. Not too bad i dont think, seeing as I have only put it thtoigh 2 cycles.

On another note, does anyone know how to remove my gmail account from the social hub? I got rid of facebook, but cant find out how to get rid of the gmail one, or even stop it syncing there.
[Galaxy S II General] d3nnisd3nnnis:
has anybody tested how long you can watch movies before the battery dies?
[Galaxy S II General] Raymond77:
I think I may have found the culprits on my SGS2:

1. The reception in my room is patchy, switched to wifi.

2. 3d Digital Clock And Weather widget - turned off the weather part.

3. Fully discharged the battery, then fully charged it, then finally deleted battery stats.

Gone from losing 15% in 2 hours yesterday to losing 3% in 3 and a half hours today!
[Galaxy S II General] vimto25:
do you use social hubs still (sync email,facebook ect..)?
[Galaxy S II General] Raymond77:
No, I rooted and uninstalled all of them. Got rid of pretty much all of the Samsung gumph.

3hours 47 minutes, 97% remaining!
[Galaxy S II General] vimto25:
would not enabling them rather than unistall give the same affect?

also you say the standard weather and clock widget you removed so u saying it users alot of battery?
[Galaxy S II General] Raymond77:
No that is not what I said at all.

I said that disabling the weather forecast portion of the "3D Digital Clock And Weather Widget" (which I downloaded from the Market) seems to have helped.

I don't use the standard news/weather widget at all.

Also I didn't uninstall the Samsung apps in the hope of improviing battery life; I did it because I don't want them on my device, period.
[Galaxy S II General] vimto25:
sorry i wasnt aware the 3D Digital Clock And Weather Widget was from the market place, so you have installed widgets/apps and now had to remove/disable to help battery usage
[Galaxy S II General] Raymond77:
You can enable/disable to weather part in the settings for the widget.

Pity really, as I like the widget as a whole.
[Galaxy S II General] mwilson1987:
How did you delete the battery stats? Do you think that this really made a difference?
[Galaxy S II General] HExa_ss:
Hi Guys.. Sorry For My Bad ENG :(

Can someone tell me how should i charged the phone first time for best battery

back-up in future ?! :confused:

is this way right ? :

#1. drain the factory charge then put the phone on charge for 12 hours(while phone is off)

#2. turn on the phone and use it until phone is die then charge it(while phone is off) until say full charge(2.5-3 hours) .... repeat this cycle(#2) three times :rolleyes:
[Galaxy S II General] renegade1488:
it doesn't really matter about charging rituals with modern phones, you're good to go when it comes out the box
[Galaxy S II General] Intratech:
I've deleted the accounts from the social hub and not using the built in email client because they are draining the battery. You can delete the accounts in the settings --> accounts and sync.

Back to using K9Mail.
[Galaxy S II General] vimto25:
you can add hotmail account to k9mail ? tnx
[Galaxy S II General] Raymond77:
Not sure if it was just one thing, or all, but this is how big a difference it/they made:
[Galaxy S II General] LBTaylor1984:
Hiw do i remove samsungs apps off this device? im rooted but im new to this. well on samsung anyways.
[Galaxy S II General] Raymond77:
I used Titanium Backup.
[Galaxy S II General] subvertbeats:
I get my SGS 2 at some point today (apparently its out for delivery :D )

When testing various ROMS / kernels for my Desire I'd use PowerTutor to diagnose what was draining the battery.

I'll do the same when the SGS2 arrives - suggest others so this also so we can see a wider set of results across different usage scenarios?
[Galaxy S II General] Intratech:
Yes. 10 character
[Galaxy S II General] LBTaylor1984:
top man, never knew you could do that, thank you sooo much
[Galaxy S II General] ndnesh:
I have a doubt. Is it ok to just not use the social hub to avoid the battery drain, or does the social hub kick in as soon as we set up accounts such as gmail and facebook through the standard settings? and is there any way of deleting the social hub without root?
[Galaxy S II General] ndnesh:
Can we use titanium backup without root to uninstall the samsung hubs?? I foresee no use for those hubs when i get my phone.
[Galaxy S II General] slyydrr:
I believe Titanium requires busybox, which requires root.
[Galaxy S II General] Mittaa:
Do not remove apps ... just freeze them !

Titanium do not need Busybox, but in order to freeze (disable) apps your phone need to be rooted.
[Galaxy S II General] Crucio_:
Hello all (first post be gentle), just got my galaxy s2 few days ago and love the phone. tho my battery does seem to go down faster than other people here. I know i'm in the use it all the time moment so i assume that has something to do with it.

But i want to insure that i can get the most out of my battery and that seems to mean removing the Samsung apps or at least stopping them.

So i will be rooting my phone soon, just been reading the guide and making sure i understood what i will be doing and had a few questions i thought best to go here being battery related.

1. Is it better to remove or to stop the programs?

2. Is titanium backup the best program to stop/remove the programs?

3. Do you need a micro sd card to backup too?

4. Could anyone give me an idea of which programs to remove/stop as this is my first Samsung and am not sure what is the bad and good things.

Thanks

Crucio_
[Galaxy S II General] Mittaa:
Titanium backup is one of the best

If you don't have root, Titanium can backup data and apps you have installed.

If you have root Titanium can also backup apps from Samsung, freeze them or even remove them.

You can use SD card and Dropbox (maby even FTP?)
[Galaxy S II General] samjpullen:
I am very impressed with the battery life on my SGS2, seems to be very solid :)

coming from a Desire with VillanROM
[Galaxy S II General] Crucio_:
Thank you Mittaa for your reply.

Could anyone else follow on from this, focusing on which programs/apps to remove/freeze. and which is best to do freeze or remove?

Thanks.
[Galaxy S II General] TheIntersect:
Well, you can freeze any of Samsung Hub ones that you don't use or don't like and anything else Samsung related.

Or anything else that is bloatware, it's really up to you ;)
[Galaxy S II General] Crucio_:
ok then i am going to go on a freezing streak! rooted and have titanium backup (paid) so I'll just freeze the apps for now and if i see no problems in a few weeks I'll remove completely.

am i right in saying if i freeze/delete something i should of i can re-flash my firmware with a the version from samefirmware.com?

anywho, thanks for the help hope this will help my battery last a bit longer with these apps stopped. sorry if it seemed like i was hijacking the thread with noob questions :)

Crucio
[Galaxy S II General] cliffahn:
Well I can vouch for the removal of Social Hub and Readers Hub.

I think Social Hub is the main problem.

So previously, with the same widgets apps etc.

I would lose around 15% or more in 2 hours.

After removing social hub with Titanium, I've lost 6%

So +1 for the removal of social hub.
[Galaxy S II General] WillClark11:
I dont really want to root my phone with it being my first andriod, is there anyway to get rid of the social hub with out rooting the phone?
[Galaxy S II General] beWater:
why not? rooting is not as hard is you think, a few months ago I had no idea about rooting and using custom kernel/rom too, but now I am enjoying the benefit from doing so. (thx xda!)

People here at XDA will help you, they are all kind and friendly :)
[Galaxy S II General] WillClark11:
With me only havin the device just over a week I dont wanna do anything that will void my warrenty
[Galaxy S II General] pulser_g2:
While it technically voids your warranty, you should be able to easily restore it so that someone cannot notice anything - ODIN lets you flash stock ROMs :)

Has anyone started to ODIN off stock, clean images for people needing warranty yet??
[Galaxy S II General] WhiteHartMart:
Battery life on the first charge already trumps my Xperia Arc by a long margin.

No nasty battery drain overnight in particular :)
[Galaxy S II General] Crucio_:
the one over on samfirmware seems to be pretty much a stock one, it removed the root and the yellow ! from my root when i flashed with that.
[Galaxy S II General] cliffahn:
Another little update.

So I've been on battery since 9:14 AM

It is now 8:23 PM

and I'm at 15%.

Huge improvement. Normally, I'd be on my second battery by now but with the removal of social hub, it seems the battery is more than sufficient.

Wish they'd program these default apps better so I wouldn't have to remove them...
[Galaxy S II General] pulser_g2:
Interesting... I'm planning to try and put together some info about all this in one place... When you say the SF one removed the root and yellow !, what is that about?

I have heard that after using download mode, some people see an exclamation point when booting... Is this related to that? And are you saying that flashing the SF ODIN image will remove that... Does it return upon future use of download mode?

And yes, this is for the "summary" thread, but also personal interest, to see how easy it is to restore the phone to a "stock as new" state, were it to be required for any reason - a big yellow exclamation point might be a good warranty-buster, if you couldn't get rid of it...
[Galaxy S II General] hshah:
I am having terrible battery drain, so after reading this thread I have frozen all the hubs.

What else can I try?
[Galaxy S II General] TheIntersect:
Download some type of battery monitor to see what it using up the battery, probably some odd app that is syncing too much.

Though, if you only got the handset recently, I'd wait a week or so to let the battery cycle and you'll be getting hours more out of it.
[Galaxy S II General] hshah:
What app would you recommend?
[Galaxy S II General] Nameless21:
First two days of having this phone I would have to charge it again after around 7 hours with not much use.

I deleted Facebook from the social hub. And use the Facebook app of the market which is still good.

I have not rooted mine and don’t plan to. Mines no network branding on. And don’t see much point. (Yet)

Looking for a ways to save power I came across an app that turns off screen brightness. It can be set to 0% 25% 50% 75% 100% or auto. It’s free on the android market called brightness level. I’ve had it off most of the day and not really noticed it. But my battery usage has changed. Look

After 9 hours 45 minutes usage which has been with a fair bit of film watching. Look at how much battery is left.
[Galaxy S II General] WillClark11:
i got convinced to root, i rooted it, got titanium backup the paid version froze the social hub, anyone got any tips what else i could freeze to help battery life?
[Galaxy S II General] subvertbeats:
Ive found Power Tutor the best for this type of investigation...
[Galaxy S II General] mwilson1987:
I don't understand how the brightness level app that you got differs to what you can do already on the phone? Or is it just that it has a widget so brightness can be easily changed on home screen?

Also, how did you get the HTC style clock/weather?!
[Galaxy S II General] Nameless21:
its just a quick and easy way to turn brightness off. on battery usage display is the highest. well on mine it is.

the clock is beautiful widgets. someone before said it was high power usage, but its been fine for me.
[Galaxy S II General] Mittaa:
Hi

Whats the name of this Battery Monitor App ?

Thanks
[Galaxy S II General] Nameless21:
that's part of android. or touchwiz. go to applications, settings, about phone, battery usage.tap on the top bit and turn your phone sideways.
[Galaxy S II General] AndyCr15:
How do you know this? Please don't say because it's not listed in the battery stats... that's not very accurate.

Also, I see you have an app monitoring your 3G usage. There's a very good chance that is taking more battery than you think.
[Galaxy S II General] Nameless21:
i know that the phone has lasted all day on a single charge with loads of use.

the apps may report wrong. but when the battery's empty then it will shut off.

which it has not yet done.
[Galaxy S II General] subvertbeats:
Its the standard Gingerbread battery usage display.

Again, for tracking battery drain issues, I always used Power Tutor with other devices. Running in now on the SGS2 so will see what its saying after a day or two...
[Galaxy S II General] hshah:
I have noticed that with automatic backlight it is too bright and drains too much battery. I was in a dark area and watching a film for 2 hours and only drained 20% battery with the brightness at 0% :)
[Galaxy S II General] AvRS:
My phone has been on the battery for 15h 36m and it's still got 42% remaining according to the battery life widget. I have hotmail setup as push and gmail through the app, facebook app syncing every hour and social hub syncing every 3hrs and weather every 3hrs. My backlight is also at 0 on the slider as it's plenty bright enough for me as don't like auto and keypad lights are set to come on only when dark. Today's usage (first full charge) consisted of:

7:15am - 5:30pm: a few texts, reading a few emails, quick check of facebook (testing social hub and using app) and a short period of web

5:45pm - 7:00pm: listening to music at the gym

7:30pm - ~9:00pm: browsing web over HSPDA

~9:00pm - now: bit of browsing over wifi and playing with the phone (checking battery usage lol)

For me my HD2 running android would well and truly have died by about 8pm if not earlier so this is a huge improvement for me and extremely happy with the battery life.
[Galaxy S II General] Nameless21:
i watched one and a half films today with brightness at 0% and it was ok. i seem to only turn it onto 100% to show of to my iphone user workmates. :)
[Galaxy S II General] vimto25:
hahaha nice :D
[Galaxy S II General] WillClark11:
Im still gettin poor battery life.. Gone down 15% in 30 mins even with the hubs frozze
[Galaxy S II General] Beards:
Well...... I have just found out the number one culprit on my phone that is eating my battery at an ALARMING RATE.

It is called 'Calendar Storage.

I charged the SGS II fully then left it completely alone. When I next returned to it 1hr 30mins later it had dropped from 100% to 51%.

I then fired up the App System Panel and was horrified to find Calendar Storage had been continually hitting the processor.

Next problem is stopping it.....

I went to the Calendar App and on to Settings which at the bottom is the Sync button.

I canceled Sync but this then stops anything syncing between my Laptop's Google Calendar and the SGS II.

If I then re-enable sync to allow entries to be synced Calendar Storage again starts up and continues to hit the processor relentlessly.

It looks like there is no way I can stop this App hitting the processor.

EDITED:

Looks like I am not alone;-

[Galaxy S II General] Crucio_:
Still not 100% if im happy with my battery life atm, tho it did last longer yesterday. Just turned it on from a dead to full charge this morning, used it for about 30min for winamp on my way to work. have JuiceDefender running and PowerTutor so hoping i'll save some more battery today and get some better ideas on where its going :)

EDIT:

Anyone using live wallpapers? it would seem silly to have such a nice phone and not be able to use them due to battery restrictions.

Crucio_
[Galaxy S II General] Beards:
No problem with the built in Live Wallpapers.

As said above my problem is to do with Calendar Storage and Sync but I have a possible fix (see above links) which I will try out later when I have finished with theatre for the day.
[Galaxy S II General] Federervollbio:
Guys, how long does it take for a full charge?

Main reason I want to get rid of my cappy is the over 3.5h for a charge...
[Galaxy S II General] Beards:
I ran my very first charge right down until it switched off the phone, so from totally empty battery til full took just under 4hrs.

That was with the phone powered off (obviously as it had zero power prior to charge) and connected using the supplied 3 Pin Mains Plug (3 Pin for UK).
[Galaxy S II General] recklesslife:
If you want amazing battery life guys then buy an iPhone 4 cause its by far the best, its amazing infact. Android eats battery life even with a big battery like this phone has and in all honesty this has the best battery life of any Android phone I've used. While its not perfect, it gets through a day easy for me. Takes forever to charge is my only gripe.
[Galaxy S II General] daleski75:
The battery life of any phone is dependent on how you use it I had a iphone 4 before getting the galaxy s2 and I could get 3 days out of mine and my friend had to charge his daily and only get 1 day and a half out of my new phone but its early days yet.

With anything like this battery life is highly subjective (apps, push email, syncing all have an effect) and I bet some people will find the battery life of their iphone sucks and vice versa.
[Galaxy S II General] recklesslife:
Yeah true enough but the battery life on my ip4 is awesome. Better than my SGS2 by far but the SGS2 excels in every other area 'at the moment'.
