Hi guys,
my first post here, but i spent a lot of time on this forum in the last days stealing information here and there so i would to thank you all for your incredible effort on get this phone better. Now i think it's time to share my thoughts about this smartphone, and ask for some doubts i have.
- Display: the size is awesome, but honestly i found it too much saturated, is there any way to change color saturation? Plus the reading is not that good... the characters, expecially without zoom, look too fuzzy. I have to admit that, imho, readability was better on my old iphone 3g. Someone feels like that? For multimedia, however, this screen is awesome.
- Lags: I can unfortunately notice some random lags while opening application or switching from market to installed apps, even with the oneclick lag fix (512 MB) installed (quadrant reports 2200+ score, if i remember correctly). I was tempted to try the hackheclair cooked rom, any advice about this?
- Battery: another pain. It seems that the phone drains the battery too fast in standby mode. In 6 hours (last night) it drained more than 20% of battery life. This sounds strange to me since many users reported an 1-2% battery drain during night. Please note that i killed all the applications and widgets before leaving the phone in standby. The only one thing that i'm unable to kill is the touchwiz UI, since i use launcherpro as default launcher. Do you know any way to kill the touchwiz UI?
- Memory: here is my biggest doubt. Shouldn't this phone carry 512 MB of RAM? When i check the running services the application reports a total of 256 MB of RAM. Where is the problem?
here are my phone details:
Firmware version JM5
Baseband XXJM3
Oneclick Lagfix applied
Sorry for the huge amount of questions, i heavy used the search engine but i haven't found any solution yet.
thanks

1. There is an app in the dev section to reduce text size, go check it out
2. That's odd, no lag in my end and i've applied One Click lagfix 1.5 .apk, i'm using SamSet's 1.9f ROM though.
3. At the moment there is no way to get rid of the TouchWiz UI but devs are working on a clean ROM, a Cyanogen mod ROM which is basically stock Android. Not too sure about the Battery issue, someone else can shed some light on that, but i do get 1-2% drop at night...
4. Eclair 2.1 does not utilize all of the RAM, and Samsung hasn't chosen to either, so we're all waiting for the final release of Froyo in a few weeks and then hopefully that will utilize all of the RAM, or there will be a workaround.
I was going to ask about the fuzzy text myself. It doesn't always seem to be so but a lot of the time the white titles of apps or text in widgets etc. It looks like it is a little out of focus but all images and coloured text appear pin sharp so far. Very odd.
your coming from an iphone 3g and your complaining about battery life and lag? you taking the piss?
and as for the screen, its better than any screen ive ever seen, i lol'ed when my mate put his iphone4 on full brightness and watched the battery go down in minutes, so dont go there with battery life.
try reading the forums and you'll find out that your problems have got a slightly better with more recent firmwares
sorry still ranting, 'fuzzy letters' roflmao!

Actually the reason for limited memory is not Eclair. The amount of memory available is governed by the kernel and the kernel on the Galaxy S supports the full 512MB. However Samsung creates a large ramdisk on /tempfs (160MB) which explains why reported RAM is around 320MB.
As for the fuzzy fonts, this is the result of using PenTile matrix in the display. Just search for PenTile, there are many threads on these and other forums discussing that.

Is there a fix ?
Not without changing the entire screen.
After a while you get used to it, it's just jarring coming from a regular LCD screen.
Don't worry about the battery, it just needs to be broken in, be sure to charge it fully then use it till the phone shuts off then charge fully 3 or 4 times when you first get it. It took mine a week or 2 but now I get a couple days of fairly heavy use out of it compared to half a day when I first got it.
Another recommendation I will give is to try not to categorize this with another device. I came from a BlackBerry and as much as I hate to admit it, I had some BlackBerry withdrawal issues LOL
I'm now a happy camper and haven't experienced the lag too much. I did experience too much lag on JM5, downgraded to JM2 and lag is gone except for LauncherPro, so tried going back to TwLauncher, was happy, and now finding that ADw is a very good launcher in itself.
Bottom line for me is that I wish there were more apps with the same caliber as the App Store's, but it does what I need and more.

Can anyone in late Eclair version's confirm the tmpfs theory (one way to do it would be to change the settings I guess so that the tmpfs is bigger, 200mb, and see if the ram drops)

It would be better with a non serif font that was a little larger. Surely this is possible?

I'd bet money this is more than just a breaking in problem. The battery drain doesn't drop by 95% (20%->1%) after a few cycles. (more on this later).

First, let me ask, do you use a task killer other than the touchwiz task manager? Do you let it run at night? If so, stop, this will cause the 20% drain nearly by itself.
Next, look at the apps that you have installed? How many do you have installed? Maybe some are doing some heavy lifting at night when you are sleeping, this is almost definitely a sync and/or app related issue. Download Spare Parts to get more detailed information on your battery drain.
Here's the issue with the battery. First, the easiest way to fix the problem should be juicedefender and ultimatejuice, but it will cost like 1.99 or 2.99. Then set up sync and maybe 3G to go off at these hours.
Cheaper fix: turn sync off at night (I assume this is running, but actually, it might not be, you might just have random data going out). Also, potentially turn 3G data off at night, this actually prevents me from getting any data and that's what I've seen improve my battery life more than anything. ultimatejuice would make this automatic (I think).
I own both the iPhone 4 and SGS, and i agree that black and white text in the iPhone generally looks sharper and more crisp. I had been using the iPhone for about a week before finally being able to acquire the Galaxy S Vibrant off contract, and i really wasn't used to the display for the first day or two. I was surprised because so many people raved about the Super AMOLED screen, yet my eyes were so used to retina display, i was able to notice the pixels on the Galaxy S screen. After the first two days though i got used to it and it looks great to me now. Actually, i had gotten so used to the customizability, as well as the Menu and Back button, and the bigger screen size, the crisper graphics on the iPhone 4 is easily negated.
Anyways, if there is a way to make text look sharper on the SGS that would make it a perfect device for me.
my battery life last very good compared to other phones
i get around a day and half screen brightness full uses for about 5 hours
wifi turned on the entire time and very heavy use
when you first got the phone did you let it drain completely then charge it completely and repeat a few times or do you just plug it in when ever ?
i had the htc legend before and the battery sucked and as for the screen
im very pleased
my bad about the RAM question, must have got mixed up

I've directly compared this screen with the HTC Desire (both AMOLED and SLCD), the HTC HD2 and the iPhone 3G & 4.
For me, its definitely up there, but I kind of agree with you on the text, when zoomed out it's not that great. That said I disagree that the iPhone 3G is better on readability - the SGS definitely is better. It's only not that great when compared with an LCD of an equivalent resolution. The HD2, Desire SLCD and especially iPhone 4 (which is stunningly sharp for text). However, its better than the Desire AMOLED.
For general UI use, I'd put both Desires and the HD2 behind the SGS and iPhone.... on the whole between the SGS and iP4 I'd say it was a draw, with both looking very sharp, clear, and colourful - the SGS is more colourful, and larger, but the iP4 is simply sharper.
For viewing pictures and movies, the SGS is clearly the best, with the best constrast, subjective detail levels and plain looks the most impressive. EVERYONE has commented on how good it looks for this. On the iP4, this is its weakness - its small screen, almost-square aspect ratio and slightly duller colours make it far less impressive looking than any of the others.
I'd rank them as thus:-
=1 - SGS
=1 - iPhone 4
3 - HD2
4 - Desire SLCD
5 - Desire AMOLED

The lags are disappointing IMO. With JM2, and the internal SD fix (cant even remember the name as there are that many fixes now), it was clearly better than stock, however not all animations are smooth, and there is a definite lag at times, seemingly fairly randomly too.
However, I've largely fixed that... some people seem to doubt autokiller, however, I can say it works for me - I set to strict or aggressive for the best results. I don't know why it works, and I can't argue against those that say it makes things worse, on paper at least, but my experience is different, it DEFINITELY helps.
Also, oddly, turning the GUI animations off too has made a significant difference. I still have the Launcher Pro animations (app drawer and pinch home screen view), and the gallery is still animated, but other GUI animations are disabled, and its a lot snappier, and I dont really miss it.
Now the only lag I get is the browser lag as in the link below, but even then Nicolocopus suggests a later firmware may fix it.

Battery - the biggest drain IME is the 3G data connection. Make sure when you're in a place with wifi to leave wifi on over the 3G data connection. Make sure the phone isn't set to send the wifi to sleep (wifi sleep policy IIRC) as the data connection will kick in while the phone is asleep. Other than that, some drain through the course of a day is par for the course.
The other thing is the screen, turning down to minimum brightness is actually more than bright enough for indoor use, and seems to make a difference.
As for Launcherpro / Touchwiz, AFAIK once you set LauncherPro as default and then restart your phone, the home screen portion of Touchwiz (TWLauncher) is no longer running. You wont be able to get rid of TW completely unless a custom Vanilla ROM is made. Not all of it is THAT bad though, really.

Cant comment other than to say, I dont know about this, so many different "opinions" fly around - all I can say is Samsung advertised it as 512mb RAM, so I think they'd be pretty stupid to give you a phone with LESS RAM than advertised - but you never know, I guess.

Aside from all this... "killing all apps and widgets" does nothing to stop the biggest android battery killer, Google sync. Google sync is always running unless you disable it.
If you really want to see how long your phone lasts in stand by, install APNdroid and disable your data connection before you go to sleep. You will have miniscule battery use during the night if you do this.

On the old DJF4 firmware, with 3G and sync on, battery drops by 2% per hour on stand-by. With the new JG4 firmware, it is now 2% drop in 2.5 hours. This is much better compared to my iphone 3GS which loses 10-13% over 7 hours on standby with sync on.

Most software I had report 326Mb total instead of 256Mb. Which variant of sgs phone do you have? I have the galaxy s i9000.
yeah these batteries needs to be drained completely before charging again, else it doesn't hold proper charge
i always push it until the phone turns off (shutdowns completely) itself, then i change the battery pack
i cycle through 3 of them

Hey guys, I recently got a Samsung Galaxy S2 (over 2 months ago)
At first it was really good with battery life, lasting over a day with medium use.
It started to get really bad, draining down from 100% to 50~ over night with no use at all.
I searched the problem and came across these forums, which said 2.3.3 was a problem sometimes.
Now this is also my first android phone, so I'm not sure exactly how to do all the tinkering around with it. Long story short, I found that changing to 2.3.4 helped a lot. It did, for 2 days, now I'm getting the same problem again. Maybe I didn't do it right? Need help! (also this forum is huge, not sure if I'm in the right spot)
Have you tried flashing a custom ROM and kernel? Pick out a ROM that you like and then install a nice kernel like Speedmod. Lite'Ning ROM v6.1 and Speedmod T39 together really increased my battery life.
Is there like a "how to" section on this site somewhere?
As I said, this is my first Android phone, so I'm a little lost as to how it all works

Thanks for the help guys.
I "think" I rooted my phone and got a version of 2.3.5, which is also supposed to be better on the battery?
just download 'start up manager' from the market, disable useless stuff that is not need ed, I get more then, a day now worth normal use.

Or also get titanium backup, and freeze all the useless crap on the phone that you dont use. I did that and it went from 7% every hour (despite the fact that there were no wakelocks) down to 0.5% every hour
EDIT- on standby/very little use, that is.
Also after you flash charge your battery to 100percent and calibrate your battery there is a good free app in the market

Well if you're using its smart phone capabilities it will really drain quickly. Specially when on data. What I did was to get an extra variety and an external battery charger-best investment for this phone ever.

You can also see what drained your battery by going into battery usage: Menu - settings - about phone - battery usage. or create the shortcut on your desktop.
download betterbatterystats to check what processes are burning your battery and stuff. helped me a lot, this app.
Given that you are getting decent performance for a bit, which then drops off, I'd say it was far less likely that the cause was the hardware or the ROM and far more likely that it is something you are doing with the configuration or software.
Try removing any widgets you have added - does that improve battery life? If so, add them back one at a time until you find the culprit. Also, make sure you are not signed into stuff like Latitude - that is an absolute battery killer.
You have seen that you can get decent life from the battery, now you just need to work out what affects that.
It was the 2.3.4 OS draining the battery. I wouldn't touch my phone, and in 8 hours it went from 100% to 20%, with the status saying Android OS 100% in battery usage.
Now I'm on 2.3.5, battery is at 95% after 4 hours.
I'll give it a few days, and see exactly how it goes and if there is a substantial difference in battery life in relation to use.
I almost had the same problem with the battery but i flashed omega rom and so far i have no problems! I always have wifi on when i am at home and 3g when i am not at home and the phone can run up to 2 days!
Have you tried doing a basic search and looking at one of the 100's of other threads crapping on about battery life?

galaxy s2 i9100 Battery Problem!
I am using Samsung Galaxy s2 for a while and I am facing an extremely low Battery Back up. Around 9-10 hrs to the max. I got the battery changed from the Samsung service center and have tried changing alot of different firmwares.
KE4 -> KE7 -> KF3 -> KH3 -> KI3 -> Simple and clean 1.2 KI4.
Nothing works.
I am attaching my "Battery Usage" images along. Please find a solution for me. Thank you.
Calibrate your battery, but you must have root access. When you have root than load the calibrate app.
i am quite heavy users on my sgs2 at first i had battery problem lasting only 5 - 7 hours... i got juice defenders free version from market and well it didnt boost my battery life to 48+ but it did made me last 1 and half day
New battery stats!!
Alright I experimented with the battery to check whether there is a problem with my battery or my firmware/kernel.
I tried the same battery on 2 different Galaxy s2. Battery stats below :
DEVICE 1:
Firmware : Stock KF3 Rooted
Kernel : Stock KF3
Battery Usage : 14hrs
Display : 45mins
Voice Calls : 1hr50mins
Battery remaining: 50%
DEVICE 2:
Firmware : Simple & Clean v1.2
Kernel : SpeedMod k2-18 test3
Battery Usage : 12hrs
Display : 45mins
Voice Calls : 2hrs
Battery remaining: 19%
Now in the above case I have used the same 1650maH battery in 2 different handsets. So why so much difference in battery life on an almost similar usage when I also made sure that the Brightness levels of both the phones also remain same.
Please help me out on this.
I have had my phone for several years and developed a good sense of the battery's life (meaning what the remaining battery percentage would be after a period of time). For instance, if the phone were fully charged when I went to bed, it would typically read 94% when I awoke.
Starting a few months ago, the battery began running down quite a bit faster than it had previously. The first thing I did was install Greenify, but that made essentially no difference (my phone is rooted, stock ROM, and I had already removed all bloatware, turned off autostarts, etc.)
Next, given the age of my phone, I suspected that the battery itself was wearing out, so I purchased a new one (a RAVPower 3220mAh Replacement Battery for Samsung Note 4 from Amazon - a battery with good reviews). However, the battery performance did not change.
Based on various recent reports about Bitcoin mining malware running on phones, today, I ran adb->shell ps -x and examined the output. The process system_server was reported as being responsible for 79% of the combined user and system times. The five processes /system/bin/surfaceflinger, /system/bin/mediaserver, com.android.systemui, /system/bin/mpdecision, and com.google.android.gms.persistent were reported as being responsible for an additional 11% of the combined user and system times; with 215 other processes being responsible for the final 10% of the combined user and system time. This makes me believe that there is no malware running that is hammering the battery.
What else could be responsible for the recent degradation of battery life? Could some device in the phone be degrading and drawing more current than it had previously? Note that I have not installed any system updates nor installed new apps recently.
Strange.... Quite awhile similar happened to me. But my thoughts was on the rooting side. Few years ago I had Note 1 and try a bunch of custom ROMs Battery life wasn't so good but I thought it was because of mostly bad battery optimization in many of custom ROMs. When I bought Note 4 I tell myself that rooting and custom ROMs are the past. But recently (God knows why) I rooted my Note 4. Since I had no time to install and play with custom ROM I left it just rooted for a few days with a stock ROM. Immediately after rooting, battery life was rapidly start to drop. I'm turning on my phone at 7 AM and about at 3 PM battery was dead. Since then battery lasts almost a whole day - at least until 7 PM. After rooting I didn't install any new app. I even didn't stop or uninstall any of apps or processes. Just did a root and nothing else. Immediately I install new stock ROM and unrooted my device. Battery life is now somewhere in the middle - dying at about 5 PM Yes, I know what is rooting and it shouldn't have anything with battery life. But at the other hand my case said that it does. Also I'm thinking - why most of manufacturers try so hard to stop users from rooting? Yes, that power shouldn't be added to any mobile phone user, but putting such effort to stop even power users of using advantages of rooted devices? Please! So much time and money spent just to "protect" users of doing some mess? There is no logic at all. So that is why I thought that Samsung (other manufacturers too) doing something "under the hood" with their devices... Yes many of "power users" will tel that I am wrong, but isn't it Samsung recently admit that they are listened (I'll be nice and won't say "spy") users of their smart TVs who had voice controls?
These days I've been looking for a new battery, but while I'm looking at your case, it seems that new battery wouldn't help me... or maybe it will? I'll give it a try.
