I too have installed the free version and is in 'agressive mode' settings. With light and moderate use, I can hardly stretch it to 20 hrs....without 3G, No wifi, No BT...

I have been a huge JD fan since it was released.
I had issues with data turning back on when the screen was awakened.
Do you have this issue?

Basically I would unlock the phone, hop in to do an SMS, use the voice search to dictate and it wouldn't connect because the data didn't turn on yet (for example).

Any thoughts on this? I may need to use this on the S2 when it comes to VZW if it has 4G.

Yes, i wonder how much it interferes with the internal workings. Anyone noticed
if it slows down the phone? What if the next firmware release fixes the battery problem,
can this be uninstalled with no ill effects ? Thanks

Periodic sync really does kill battery -- an alternative is something like https://market.android.com/details?id=cz.psencik.simple.autosync -- this way non-critical sync can be made far less frequent.

Seems to have pretty good effects - maybe not as good as that above, but more usable with less impact ?

Yes, I do suffer with this.. Not found an easy way out of it except for disable and re-enable..

It doesn't happen every time, so far it's not a massive issue but yes, it would be better if it was correct

13h10m into the battery I have 76% left. I've just sendt a few SMS and 1 call today but I've read an ebook for a couple of hours. With my light use consisting af a few SMS, a few short calls and 2-3h ebook reading I guess I can squeeze a couple of full days out of the phone. But as soon as I start playing Angry birds it kills the battery quickley. I don't use JD but I close open apps using an included app that I can't remeber the name of right now but it allows you to see space usage, close apps and empty RAM.

To uninstall, make sure you have data ON. Then uninstall or you could get stuck.

You don't need to use the data on/off function on JD, you can just set your sync to ping every 15 minutes. Different than the data/3g turning on and off.

The multiplier widget is pretty accurate too.

Impressive!

I never had JuiceDefender on my own phone, but after some tweaking with settings and knowingly avoiding 3G/WiFi usage and lengthy calls (basically some few 1-4 min calls and some 50-70 SMS'es), I managed to run my S2 for 79hr 56m once with 28% left on battery (I used it on WiFi quite a bit after this, since I did this to see just how long the battery could last with light usage). Again, this was done completely without JD.

Am gonna try JD once I get my phone back from check-up. But I do not think you -really- need it, if you just sit down and do some tweaking with settings. Reducing screen brightness manually to lowest setting is one of the things that drastically increased the battery life for me. Made it hard to see the screen well in outdoor sunlight, but still...

Hmm, I have let my phone run idle for 4 hours and only 2 % drop. What i did was turn off wi-fi, data packets, GPS, blue tooth, changed my background to black, and turned of syncing. Hehe, I know, what's the point eh? But at least the phone will last over a day and i will still be able to receive phone calls. If I need to surf the net I just turn on wifi or 3g connectivity.

Dear All with JuiceDefender

Appreciate if you could test the following eg

1) Using Wifi, try surfing the net every 5mins eg Refresh would be fine.
I can't get more than 4.5hours (without JD) from 100% battery charged

2) Watching 200 minutes of movie.

If you are able to do more than the above, pls let me know, then I will install it.

Regards

Isn't it ridiculous the way everyone is talking about the battery life, it is clearly an issue, and personally I would have preferred a thicker phone (larger battery) and a battery life which is at least close to the standard of the phone that we own.

No point in designing a Rolls Royce of a telephone, and putting the engine of a mini inside it.

I have this app and i am a bit confused about it
On the ABOUT bit on the screen it says that JuiceDefender has increased your battery life by x1.17 - is that good? Is that was everyone else is seeing?

this phone is more faster and powerful than my home pc. and its in my pocket. i dont see it as an issue, i expect that if i use it lots with what it CAN do, it will drain my power.
Such a vivid and large screen running from a dual core WILL suck the juice, you cant expect "high powered drag car to run a endurance race on 1 tank of fuel" can you?
there are lot of other phones out there that will last longer but do they have a 4.3 super amoled screen? a dual core processer? 8mp camera with highdef playback?.no.

i use this as a normal phone and get 4 days out of it. i use it to its full extent and average 1 day. i expect that, im happy with that because i knew that BEFORE i got it. find a smart phone that lasts more than a week with FULL abilities running and the same specs and get back to me.

most just want to get the most life they can get with any help appreciated. Some are faulty yes, but i dont see a problem, just keen consumers who are use to over a weeks life with older slower phones.

I get where your coming from completely! I got my SGS2 three days ago and everyday Ive had to charge it, would hardly last even a day! I suppose that was because I was using a lot of features, but whats the point if I cant even use the features on the phone for fear of draining the battery!

Samsung definately should have put in a bigger battery, maybe twice the capacity!

Is there a larger/bigger battery that would offer more Juice for my SGS2 and its compatible with it?

I have an S2 as well, lasting full day of semi heavy use for me is a good deal as I charge it over night. My last phone would only last half a day even with no wifi on

Not at all, if you dont use it at all and let it stand by, it will keep working for over a week.

Then again, whats the point? It's the screen that kills the battery in general. There are some apps that are power hungry of course.

The bottom line is, if you want to preserve the battery, dont use the phone.

I am sgtarting to get a bit frustrated with mine, the phone is fantastic, the battery is rubbish. It's a real design issue.

i dont see hows its the battery's fault?

a 4.3 super amoled screen which is EXTREMELY bright and vivid...its amazing.
thats your "design" issue.

put the same battery in a different phone and do you think it would do worse than its own battery???
its not the batterys fault at all. make the same phone with a smaller crap screen and it would last over a week easy. whilst your there, grab an iphone battery, put in this phone and watch the difference. none i expect.

Default Its a Smartphone

A smart phone sucks up battery. So just live with it. I don't think its actually the battery's fault other than that you can always use a larger capacity battery. But then its not gonna be as thin, or good looking.

Anyway, My SGS2 could probably last 2 days with light usage. Heck probably even 3. But truth is, I can live with charging every night. Last time I couldn't maintain 1 days usage but now no problem.

I maintain screen brightness at 25% and I off data (3G) unless I want to use it. Today, I had 30minutes of calls, using Go launcher Ex (which uses more battery than stock launcher), use the polaris office for 5 minutes, use Kobo to read a short story, browse the web, update apps through android market, and played angry birds for 1 hour (boring meeting and after noticing I had 67% battery left after 8 hours of usage).

Its now 13.5 hours and its down to 11% and I am charging it now.

Anyway, like I said I could get it to last 2 days with light to moderate usage, but I am more than willing to live with one day since its a SMARTPHONE. And I want to use it.

Didn't bother with juice defender or anything like that. I notice a big difference if you leave the 3G running, which you don't really need to. Just on it after a couple of hours or when you want to use it. It helps a lot. Now I get to play games too before the day is out .

Cheers

PS-Doubt most smartphones can actually last as long as the SGS2 with the same specs and usage. Don't forget, IPhone got a smaller screen.

I agree with Russell, for a phone with such an impressive screen and doing all the things it is capable of I am more than happy with the battery life I get. As long as I can get a days use out of it under heavy useage I am happy. The best I have managed so far is 3 days 16 hours and by that time it had gone down to 6%. That was on relatively light useage but even so thats' impressive for a modern day smartphone.

Unlike most phones it doesnt seem to drain power when it isn't in use.. for example after charging during the night I generally wake up to find it at 100% and unplug it. By the morning after a further 3+ hours it has remained steady at 100%. Currently 5 hours after unplugging the charger it is showing 99%.

Occassionally I will see the battery drop quite quickly but I have found that simply turning the phone off for a few minutes and then re-starting cures this. I can only assume that some app is stuck working in the background that the task manager isn't able to kill.

Clearly some people are having problems and I can only assume that they have dodgy batteries.

In reality, all talk about battery life extension is futile if you use any smart phone as it is intended to be used, ie web browsing, video watching, music listening, call making, texting, GPS, etc.

No matter if you use juice defender or not, when you use any smart phone to its full potential, you will see the battery drain before your eyes. At the end of the day the Galaxy S2 is a powerful little computer in your hand and current battery technology has unfortunately just not managed to catch up... yet!

Same as with a netbook and lap tops, you will see the battery drain as you use it!

So I dont see the point in comparing idle battery times?! There is also no point in complaining about battery life with the S2 because with mid-high usage, it drains as much as any other smart phone!

But i will agree that for those times when your phone is idle and screen is off, juice defender is definitely worth having. I recommend flight mode overnight!

I don't understand whenever someone mentions putting a phone on flight mode overnight to save battery. If you're going to sleep overnight, wouldn't you end up with more juice (100% to be exact) by plugging it in as opposed to entering flight mode? I also assume people sleep in rooms with outlets. Another benefit would be missed calls being logged.

I wouldn't like to leave my Phone plugged in most nights while i sleep, especially when it's not completely drained. It will take less than 3 hours to charge and the rest of the time it will be receiving power to which it cannot store or use. Repeatedly doing this can (not saying it definitely will) cause damage to the battery either by shortening workable use or cutting the amount of recharge cycles it can handle before it dies.

Interesting concept. I am a power user who streams feature films, surfs and games and absolutely must charge nightly, and it never occurred to me there are those who can get through the day with 80%+ juice. I always assumed that after our phones reached 100%, it somehow stopped charging to avoid damaging the battery, whereas before smart phones, you had to manually unplug chargers to avoid damaging the battery. I do notice a 100% icon on the top left after fully charging, and assume, much like a laptop with no battery inserted but plugged in, that the electricity from then on would safely only affect the phone and not the battery.

I have just bought a spare battery for the sgs2. But when I got it home, I realised that I have to put it in the phone to charge it.
Does anyone know if you can buy a battery charger separate from the phone. This would solve my problems as I am trying to alternate charging and use of these 2 batteries to extend battery life of both of these batteries. IMO I don't mind charging overnight, but I didn't know you could shorten battery life by leaving on charge overnight. As long as you let the battery discharge completely before recharging, I think is OK. It is difficult to let the battery completely discharge before reconnecting to charger. Also, I am not able to turn phone off whilst charging as I don't want to miss any calls as I am on 24 hr call.

Any separate battery chargers available?

Really pisses me off people claiming days and days worth of battery - you look and they have not "used" the device.
No Internet or HD Games, no GPS apps or Media - just OS running.

Best you can get out of the S2 with proper use is a day. 4-10 hours heavy use (big games, gps navigation etc) if that.

Then move on to another topic - simple.

Your "proper use" will surely differ from mine, as will that of many others. Even with the same person, usage can very greatly depending on circumstance on a particular day. That's why people compare battery performance at idle - it limits other influences.

After all, nobody expects a smartphone to not use power when working. Minimising unnecessary use when not working is surely a good thing, however?
