Short report on this dream machine:

Got up at 6.00 am and started to download apps, apps, apps, syncing emails back to 100 days ago, calendar, checking apps, playing around with opera 11 and new apps and so on, when driving google mapping and music playing .................

Let´s say continous heavy use

With juice defender on now at 6:00 pm I am still on 41 % which is excellent compared to my HD2 and Touch HD ................. :D
[Galaxy S II General] zebbi24:
i got pretty much same usage and got 1day 14 hrs.screen on time was 4hrs 30mins.im with the group who can see the battery easily doing 2 days with custom roms etc.i have wifi on the whole time im at home.twitter every 15mins etc 50 txts,little browsing 20min, played 15 mins of modern combat,showing off to mates etc id call it medium use.i was getting about the same life with sgs1 so im pretty stoked considering all i have done is got root.nothing custom yet
[Galaxy S II General] skaif:
Yea so my average day went like this...

That was around 3hrs screen time, screen on 1%, 1hr music 1hr phonecall and light browsing and navigation for an hr...is this on par with you lot?

Also. This is slightly worrying

I have no issues making / receiving calls or txts and my internet is always on...
[Galaxy S II General] computermilk:
Which Juice defender did you install? and did you leave it on the default settings?
[Galaxy S II General] slyydrr:
I would actually say not to worry about the 100% without signal. It's inaccurate (mine does the same thing and I always have a signal). There's a bug somewhere in the calculation so it should be ignored until fixed :)
[Galaxy S II General] skaif:
Thanks for your feedback, looking forward to that fix! On a related note. Any1 know how to change between 2g/3g? My coverage @ work is crap so this may help....

[Galaxy S II General] SBS_:
Hmm don't have my phone set to english atm, but it should be something like this:

Settings - Wireless & Network - Mobile network - Network mode - Choose GSM only for 2G/Edge
[Galaxy S II General] skaif:
Cheers guys! :) saw those settings before but dint knw they did 2g/3g!!!

Hi

Can someone tell me what is the battery app name? I like it :D
[Galaxy S II General] dk206:
Are you talking about the screenshots? Its not an app it is built in already in Galaxy S and Galaxy S II
[Galaxy S II General] lhrrob:
I am taking about the status bar battery icon that tells you, in percent, how much juice is left in the battery :rolleyes:

Sorry :) you really could understand me wrong.

Already posted this in the Android Service Battery Thread.....reposting here as it may help

This might help someone.........My SGS2 was eating about 6-7% of Battery per Hour on Screen Off Idle........i.e. no Phone Calls, Texts, Internet Browsing or other Screen Based Activity..........but 1 off Exchange and 4 other Email Accounts on Push running in the background

I was still using my SGS1 as my main phone and thus minimizing real-world activity of Calls, Texts and Internet etc.........Over 2-3 days, I was getting about 15 hours of Battery Life before battery depletion.........obviously not good and certainly not enough for the phone to become my "main" phone

So, I charged and Re-booted phone.......went into "Running Services" and "Stopped" the following Services which were running

** Social Hub (seems like there are two different versions running)

** Wifi Sharing Manager

** Wifi Sharing

** Software Update

** Game Hub

** And several other running Services which IMHO did not need to be running

After stopping these services, I've now run for another 2 days.........Battery Usage is now down to about 1.5-2% per hour on Screen Off Idle

e.g. this translates into 37% Battery Remaining after 28 hours of "Uptime", including

** Screen on for 1 hr 37m

** 39 minutes of Phone Calls

** Push Email on 1 Exchange plus 4 other Accounts

** Some Browsing and Hotspot testing for about 20 minutes

** Live Wallpaper and several other Widgets running

Starting Wifi, Hotspot or Kies Air results in Wifi Sharing and Manager Services restarting........disabling Wifi or Hotspot does not turn them off........so Whenever I exit these, I re-enter Running Services (using a home screen short cut) and Stop both the Wifi Services

I'm now happy that I should be able to get about 20 hours of reasonably Heavy Phone Call (120 minutes per day), Internet, Texting and EMail activity and thus it will become my main phone........could be better, but enough to get by

I still think I will need to keep a constant eye on Running Services to disable any that I don't think I'm currently running

May or may not help someone........it's a super phone and better in every way than my previous SGS, HTC Desire, Desire HD, Iphone 4, HD2 etc.
[Galaxy S II General] ShaggyDragon:
I've certainly fixed my battery drain. Before I was getting 7 hours out of the phone. Now it's dropping 1 percent per hour on standby. I switched to GSM only mode. The 3G reception where I live is poor due to the construction of the building.

I wish we could get the Toggle 2G app working for this phone. There's really no reason to have 3G enabled when you're on WIFI. The app details are here:

http://xdaforums.com/showthread.php?t=739530

Anyone find something similar that works? Are there any 2G/3G toggle widgets that work?
[Galaxy S II General] Bajaj_86:
I think something wrong with either my battery or the phone itself. This is my third day of using the phone. The maximum battery time of the second day is 9 hours 30 minutes before the screen was totally dead.

Today, I charged the phone with the turn-off condition. Turn On the phone at 9.30AM, after normal browsing (reading news, downloading some apps) and playing some Angry Birds the battery lasted for only 5 - 6 hours this time.

Can anybody help me with this? I am pretty tired of losing my battery in such short time.

Has anybody encounter the same problem?

I'm pretty worried about this thing. Please somebody help me.

Juice defender free, balanced mode
[Galaxy S II General] Beards:
As there are some users (myself included) who get very good battery results I still believe it is primarily in what Apps are installed and how these are given permissions.

I know there is an issue with Gingerbread but I do not feel this is causing the heartache certain members are having otherwise we would all be experiencing the problem.

What I would propose is for you to carry out a Factory Reset and then do a full charge.

DO NOT install anything for the first 24hrs, just do the normal setting up of the phone and leave it to see what the drain is on a 'vanilla' phone.

If then you find your battery has improved set about adding your Apps slowly just to see if you can pin-point any that may be hitting the processor excessively.
[Galaxy S II General] D4rK.F0rcE:
Is there an app or a way to automatically disable some services? It's a bit annoying to manually disable services after every reboot.
[Galaxy S II General] walda:
you can freeze them with titanium backup.

im also also using around 2% a hour in idle still way to much though should be like 2-4% per day
[Galaxy S II General] shawnfr:
Running the latest XDJ installed via kies.

Just noticed phone was getting very warm and looked at battery use...SyncmIDS taking 55% overall and 96% CPU! Killed it using OS monitor and phone cooled down :)

Anyone know what SyncmIDS is?
[Galaxy S II General] slyydrr:
I too am curious as to what this is. I have frozen it before and everything seemed to run okay, but for me it is currently unfrozen.
[Galaxy S II General] siksik6:
all,

My handset was bought from O2 as a PAYG handset

I was getting a dead battery in less than 12 hours after taking it off charge, with very light usage.

Last night I flashed to the generic firmware using a guide in another well known forum (not sure if I'm allowed to link it..) now my battery is VASTLY improved.

It's now 9 hours since it's last charge, and I still have 55% battery left. So about 20 hours until it died I expect.

Much better. For those that are still struggling with battery life, give this a go. Seemed to work for me!
[Galaxy S II General] kreoXDA:
It is a Data Synchronization service that is employing the open source SyncML standard.

I believe Samsung is using it to support that Settings menu item "About" -> "Check for Update" to ring the home base and inquire about updates. Although it may be used for email, calendar and task sync also.
[Galaxy S II General] dk206:
Battery 50%
[Galaxy S II General] JeankDragon:
I have a question, it is assumed that dual-mode (GSM / 3G) the phone should give better performance? or is it better if you just keep on 3G? :confused:

I managed to use up to 26 hours, however in the two subsequent charges have not reached 15 hours
[Galaxy S II General] JeankDragon:
Wow, my first charge lasted me an approximate 21 to 24 hours, then had two very bad days where I gave a very loose use the phone and when I got up 17 hours.

I am currently 20 hours, and attached the battery performance, which is 65%, I have not used the phone excessively, in fact I have not sailed, but if I use facebook, and many emails and some calls.

The screen is very low use, but the strange thing is that I have used with some frequency, at least between 5 and ten minutes per hour, so yes, includes six hours of the night which is not used the phone, a pair of That post itself.
[Galaxy S II General] Dombledore:
I've had the phone about 10 days now; I can't remember how many charge cycles, but this is on the same one as my earlier post. I just got over 2 days out of it...

[Galaxy S II General] AndyCr15:
That reminds me, does anyone know why power save mode puts that symbol in you notification bar, even though it's not in effect (for example, I set mine to kick in at 30%, but the symbol will show from full charge all the way down....)
[Galaxy S II General] SBS_:
To show you that a power-saving mode is active?

Of course it would be better if the icon didn't show up until 30% so it's probably just lazy programming. It could also be to not have to program it to poll the battery level so that it only displays below 30% as that would drain your battery just ever so slightly. As it is programmed now the icon displays when you use a power saving mode and doesn't display when you're not, a simple yet effective way to program it imo.

So that's probably your why :p
[Galaxy S II General] PLNY8789:
Hey. Bit off topic, but does anyone know where i can buy a genuine Samsung Galaxy S i9100 house charger?
[Galaxy S II General] AndyCr15:
But that's what I'm saying, which I think you did get from my point, that it's not active until it hits the point that you set. It has to be checking the battery % anyway, otherwise how does it know when to turn on! :)

If I had a warning system in my car, to tell me when I was speeding, how much use would it be if the warning continually goes off when I turn the system on and nothing changes when I actually go too fast.

Very silly in my opinion.

Hmm... I don't think they can charge your house. That should be on the mains grid of your town :p
[Galaxy S II General] PLNY8789:
Lol funny. Im after a 240 volt charger to be used at home. :)
[Galaxy S II General] prophet42:
IF you don't have titanium backup, go into the normal android phone settings (oddly you can't remove the accounts in social hub - how random!!), select accounts and sync, then under the manage accounts section select the social hub ones, and click remove account button at the bottom.

Go back into socail hub, and you should find all your accounts removed. Unless you got google mail on, and it seems to have difficulty if you are syncing your phone book, but that's no big whoop.

For the record, I have my social hub on, and my battery is draining like a mother f**ker. 10 hours? I'm lucky if my battery isn't down to %60 after 2 and a half hours of moderate use. i.e. messaging people, using whatsapp with facebook updating in the background with status updates and me commenting on them. I've just removed the social hub, so far after an hour still on a hundred percent and messaging. We'll see how it goes.
[Galaxy S II General] vimto25:
So this social hub is a big battery drainer? can any1 else clarify this?
[Galaxy S II General] NeoVR:
Theres also two "modes" of charging.. USB and AC.. i think the usb mode is for 500ma and below with charge rate about 300-400ma - in this mode my old desire would still loose charge if i was running something like navigation.. Also alot of aftermarket chargers would only let the phone charge in USB mode..

AC mode can be up to 1amp i believe and the phone will charge at 700-800ma (the desire did anyway)

I *think* the above might be part of the microUSB standard.. i cant verify it against the desire because currentwidget doesnt work on this.
[Galaxy S II General] prophet42:
Since then I've gone 2 hrs 45 mins since charge, battery is at 89%.

I've commented on one facebook status using facebook for android.

sent 4 text messages.

made one phone call of 2 minute duration, and received another of 27 seconds.

used live profile to send 5 messages, and received 5.

Installed 2 new programs from market place (2 keyboards) and tested them.

Thats all, and it's drained 10%. I have beautiful widgets sycning with weather every hour, along with Facebook auto updating notifications.

Not sure if that gives anyone a better idea of battery usage, so I'm not sure if turning off the social hub sycning is making a massive difference here. Need to do some better tests really.

Oh one thing of note, I got my Galaxy S 2 on Thursday, and there is a fault with it. When I take a photo, or video there are two black marks that appear on every image/video in the same place. I've checked the lens, no scratches. Done a factory reset, still nothing. Taking it back to phones 4 u today for a replacement.
[Galaxy S II General] zxz0O0:
In USB 2.0 you can only charge with 500mA. If you charge more you may damage the usb port. USB 3.0 is 900mA.
[Galaxy S II General] prophet42:
Apologies for the last small bit of my post, I realise camera has nothing to do with this thread, but I can't edit the post for five minutes or something.
[Galaxy S II General] Raymond77:
I'm probably going to have to buy a second battery, it's so bad.

Lost 15% in less than 2 hours, with it sat there doing nothing. I've turned off "Background Data" in accounts, uninstalled all of the Samsung crap and only have a few widgets running. Pathetic.

I may get rid of all of the widgets to see if maybe one of them is what is causing the drain, but at the moment I'm very disappointed with the battery life, especially after the reviews have all banged on about how good it is...
[Galaxy S II General] vimto25:
thanks, Yes i think it needs more testing to see the exact power drain social hub makes, I notice its going to make some wat of a drain but there can be excessive drain which we need to avoid.

Strange problem you are getting maybe u should make a thread so otehrs can check to see if they have the same and also within the next week others will receive there phones.

Is yours sim free?
[Galaxy S II General] prophet42:
Fraid not. I got mine from Phones 4 U in Weston Favell Centre, Northampton. Familiar story there I'm afraid, they were getting on average 5 or 6 phones a day, but weren't selling any sim free as they claimed they wouldn't make any money off of it and were surprised when I said about some people being able to get them.

The taffifs were definately worse than they offer online, most average £35 a month with no money down.

Mine was orange, £35 a month, 750mb data, unlimited text messages and 900 minutes.
[Galaxy S II General] epicfailguy2:
I'm pretty sure you have some retarded widget like beautiful widget (worse widget ever for battery life, poorly coded, SiMi clock & weather are much better) that keeps the cpu at full frequency all the time lol. You should go in battery stat menu to see which app drains your cpu time.

Aswell install Juicedefender for your syncing, will double your battery life or so.

Some Korean post at Korean forum that it died after just playing 720p vid for 5hr 53min under mid level brightness and volume and wifi/gps off.
[Galaxy S II General] flooki:
Just? Excuse me but I think that is pretty good for HD video playback - I don't see how you could except much more.

EDIT: I actually remember reading about the Optimus 2X and that when watching a 1080p movie you get about 90 mins out of it - just enough for a feature length film... just for comparison. Of course, 1080p is bigger, and maybe Wifi was turned on - I'm just pointing out that 6 hours seems fine.
[Galaxy S II General] f15hh3ad:
I might be wrong. but lets focus on he did turn off wifi/gps. is it good? im not sure.

[Galaxy S II General] ghost77:
You will get a little bit less with normal Galaxy S , less if its high bitrate 720 mkv , and up to 7 hours if its low bitrate xvid's .

I don't expect any miracles or worse from SGS2 , pretty much same battery , and even thought hardware is much faster power usage is probably same or similar.
[Galaxy S II General] Shaady:
Not impressed by the battery life at all, full charge this morning, very light usage since then (about 10 texts, some light wi-fi use) and im on 28%. Not what I was expecting. I am going to try turning of the social hub, as I have my email and facebook accounts on it, and see if that makes any difference.
[Galaxy S II General] risq:
wow....lots of diversity on the battery feedback...

Then again, modern batteries do need to be conditioned, ,and I know the first few charges are important to that.

I presume you allowed a full discharge then a complete charge, rather than topping up, as that's not very good for the batteries, especially when new.
[Galaxy S II General] rouvax:
Do not use facebook syncronization , this wil change alot.
[Galaxy S II General] AndyCr15:
All I would suggest, those with poor battery life, rather than 'this is a crap phone, crap battery' think 'what do I need to change? What's causing this as others do fine?'. That's how I usually look at it and I can usually go from crap to good.

For me, first two days less than 10 hours on moderate usage, now over 20 hours each time.

It may simply be you have much higher demand from your device, but I think with the Facebook app and the Social hub (for example) the poor phone is syncing stuff all the time, and probably the same stuff!
[Galaxy S II General] NIK516:
Hey how did you first charge your phone? did you do a long uninterrupted charge for 8 hours or did you just start using it straight out of the box?
[Galaxy S II General] vimto25:
i agree, the facebook widget on the DHD for sence drained the battery and had much improvment when disabled, was shame but theres alternative programs, Not sure your going to find a device that can sync constantly with mod-heavy use and the battery going to last very long. As others said give it a week or so to charge and discharge and re think about what you got running and im sure youll find some improvment.
[Galaxy S II General] khein:
I think the first charge is unimportant. That battery behavior is actually normal on gadgets.

In the first days, you will be charging the phone frequently as you are constantly using it (installing, benchmarking, testing every features, exploring, call, camera, video/playback, sms, some gps, games, wifi, etc). After a few more days or weeks, you'll feel that the battery lasts longer because you are most likely using it normally(call, sms, some gps, games, wifi, etc).

Probably in his case (he said he used it normally even in the first days), he must have tweaked the phone or the battery-phone calibrated itself after usage (some people reports that they can still use their phones in 0% battery so maybe it is possible that the phone will display 100% battery even if in reality it is still not yet full).

Except if you've installed a battery hog app or you are just a really really heavy phone user.

Though this is only my opinion. :p

My first post. Yey. :D
[Galaxy S II General] prophet42:
Definately. Modern lithium ion batteries are designed to allow constant topping up without reducing life (well realistically speaking - obviously it will over years of use). They don't require full discharge and then over charging to increase battery life like old batteries did.

For example I am using my second Galaxy S 2 now, the first I returned due to camera defect. That one I did a full discharge, and then charged it up over 18 hours.

The second I used straight away and have been topping up the charge ever since, and the second has by far had the better battery life. 4 hours of moderate use, and it only dropped by 10%.

The key difference has been tweaking apps. The first thing i did between phones was stop using the socail hub to update facebook, email and everything else, and dump beautiful widgets. Since this I've noticed the battery life is running a lot better.

To each their own, play around with apps and how they update and you'll get a happy medium until they invent a proper high capacity battery we can all use with apps updating in the background playing music and video at the same time =) Oh how I wait for that day!
[Galaxy S II General] troed:
stop using the socail hub to update facebook, email and everything else, and dump beautiful widgets. Since this I've noticed the battery life is running a lot better

Please explain in more detail WHICH widgets You dumped exactly and if there are possibilities to tweak the update scheme for facebook and gmail separately (e.g. facebook twice a day, gmail every four hours etc.)

Sorry for busting You with this but I get my SGSII in one week, so no way to see for this myself ..........

Tx in advance:D
