My Everyday phone is an S2 from way back in 2011 but I love it, I'm running KK and repartitioned the internal storage to 8GB and it's the best it's ever been, 4G & NFC would be nice but it really does everything I want.
This week I bought a faulty S2, sold as wifi would not work and overheats phone, the idea was if anything every happens to my phone (smashed screen, USB damage etc)I can swap over the main board in half an hour and I'm up and running again. Best of all I only paid £30 for it and it's in A1 condition (better than mine).
Having done some research I discovered the BAT500 issue with the S2, sure enough I opened her up and the button battery had leaked on the main board. Not an issue because as a donor the main board will be swapped one day.
As I had it apart I cleaned up the acid and it's now working perfect again.
But....... the big question, my daily is over three years old, the battery could be leaking in her too, if not it might soon! in fact the way I see it we are all sitting on a time bomb!
So, does anyone know if the BAT500 call can be removed (not replaced) to safeguard future issues? If removed what will the effect be, will it just be loss of back up (time, date etc) if main battery is removed?
I'm tempted to try it on the donor but now it's working perfectly I'm a bit loathed to do it, and I have already repartitioned the PIT to 8GB and loaded KK on it.

A google of BAT500 S2 reveals the issue further.
Found this great info after more searches, I will be removing battery's from both phones starting with donor.

Quick update,
Dead easy to do, half hours work and both batteries removed.
Really easy, light rock and it comes loose then lift and the peg snaps. The BAT500 in my everyday was fine but I'm taking no chances and it's been removed to avoid the risk of acid leakage and keep my lovely phone going and ready for a lolly
Donor battery on left, everyday (good one) on right.

I have no WiFi problems about connecting but it's too slow. If I replace batteries with new ones would my connection works like any other phone? What do you think?

No, this has nothing to do with speed, the BAT500 simply retains the time and date if you remove the main battery.

Simple scenario: I have a couple batteries, I'd rather use one and then swap it out when it's 10%, inserting the other charged one.
With every device I've owned, removing the battery didn't automatically lead to losing the date&time settings (not even on my Nokia 6111, as long as you were fast in plugging the new one in), while with this expensive beast of phone, it appears that even if you slightly flip out the battery and reinsert it in a matter of less than a second, rebooting WILL lead to the clock being reset to the first of january of the year 2000.
On my HD2, leaving the battery out for half a day didn't reset the clock.
This behaviour doesn't change whether you set the clock to automatic or not.
What surprises me is that noone in the internet seems to be swapping batteries on their S II, because noone else reported this problem.
Do any of you have any kind of suggestion?
Leaving the clock to "automatic" also doesn't appear to be resetting to the correct date, not even if I set on and off airplane mode to re-shake with my carrier.
Does the fact that noone replied mean that I am the only one having this problem (which would call for a warranty servicing), or that noone ever needs to swap batteries, or lastly that noone does even care?

1 2 or 3 .
Or more likely nobody has read your post that knows the answer YET.

Quite right, quite right
For starters though, since this would somehow ease my mind, does your clock also get reset if you unplug the battery for a short while? (suppose you own a SGSII as well since you're in here )
No and i would guess yours is hardware fault .
jje
....sucks.
I would exclude it depends anyhow from the custom roms I've installed, I never tried unplugging battery on the stock rom before flashing.
This never happened to me in any new phone. It used to happen in my old Nokia phones when they get old (after 1 or 2 years)
There is an internal battery to keep the clock which died in your GSII.
Warranty shall cover it
Yup, apparently this is the only expanation. A huge bad luck.
::bump::
So here's the news. Had to wait for monday to come in order to call the phone support.
Not very much surprisingly they told me that the system clock resetting to Sat 1 Jan 2000 whenever you take out the battery is "perfectly normal" (yeah, welcome to 2011).
Which collides with what you, @JJEgan and @salamt, reported.
So it makes me think the gal at the phone was bullsh*tting me.
She confirmed though that flashing custom roms will invalidate the warranty. No change there.

I take my battery out frequently and clock stays the same presume left out for a couple of days it would lose the charge and clock reset .
1343 battery out
1346 battery in
boot phone
time reads 1346

So this is a good indication of how samsung support tells you nice tales. Actually this scares me more than the fact that the phone's backup battery was DOA.
Hi ephestione,
my S2 keeps the clock running without battery at least for half an hour, so i assume your device has an malfunction with the internal battery as user salamt already has stated.
I did sent in my S2 already 3 times to Samsung warranty support because of another hardware fault (sound of lower Microphone is very low and stuttering, so people have trouble to hear me).
Everytime i get it back my clock says something with Year 2000 - Hey the phone isnt that old
My HD2 is keeping the clock running for weeks without an battery ...
Send in your phone for warranty, if its important for you to switch batteries.
But be aware, Samsungs customer support isnt the best
I did buy the official Samsung 2000mAh battery with nice cover from Amazon and its nearby not possible to suck the S2 empty on one day.

More confirmations about this glitch of mine, that is a real glitch instead of "completely normal feature" as the Samsung support would like to pass it by.
Thank you for adding yet another precious feedback with this aspect, as now I am positive the phone is defective.
You are correct, the phone doesn't have internal batteries, it's a capacitor, which runs the timing chip, which controls everything on the phone, which without power should run for about 48 hours give or take. Faulty capacitor is definitely grounds for a warranty repair, and if you gets someone who says it's "normal" ask for their supervisor, and if their supervisor is still that ignorant, keep going up the chain.
You have to realize that "customer support" for most companies basically work the same as insurance companies, the fewer the claims, the better, so if you can make a customer live with an issue that doesn't kill the phone, they do it. However, a faulty capacitor can surge a mainboard, and truly kill electronics, get it fixed while you still have a warranty to fall back on!
I chose the quick way around. Sold the phone
Sure my hd2 now feels like a slow brick compared to the superlight all-plastic S2, but at least I know it's been making me company for the last couple years, and I trust it.
sorry for digging up this old thread but im having the same issue after flashing so many ROMs. It never happened to me.
Just to confirm, is there really no "battery" or some power source (like the BIOS battery) for phone to "remember" the time and date? Instead it uses a capacitor? just wanna know in case customer service bull**** me. But i dont think a battery (even those coin-sized) would fit in the sgs2
Since I've long since sold my SGS2 and now am using a SGN, which does remember the time after a battery swap, I can tell you definitely it's a hardware problem.
Alas, support WILL bs you if they can, but I suppose if you know they are doing that, you can make a strong voice and have them issue a repair/switch service for you, by telling them up front you know you're right and wll be speaking with a superior/write anout it on your blog.

I agree that they were BS'ing you. Otherwise, why would there be component BAT500 which other users have reported Samsung service centres have told them has leaked and destroyed their WiFi chip? http://code.google.com/p/android/issues/detail?id=28036#c471
BAT500 is an EDL Capacitor which stores charge while the battery is in then slowly dischargers when the battery is removed. My phone started loosing the clock immediately when the battery is removed but its stopped now. I believe its could be one of two things but I can't be 100% sure. I had my phone on charge every night for that last couple of weeks and I noticed the issue. Over the last two days I have let the phone run flat and charged it again and now it remembers the time when I remove the battery for at least a minute. The other theory is that I also had wifi always on for the last couple of weeks and that also has been off for two days now. The wifi chip is right next to the capacitor and if the chip was to get warm it could cause the capacitor to malfunction.

thanks for all the valuable inputs. i will go to SSC next week. Have been putting it off cos tmr i am going overseas and i nid my S2 with me.
Hopefully they are willing to change.
EDIT: and i realised it happened to those who root and flash ROMs often
Hey guys, a friend of mine is selling his 8 month old S2, and he is willing to give it to me for a good price, I was thinking it would be worth the upgrade (using a i9003 now) and a brand new galaxy nexus is just too expensive (so are the other 720p screen resolution monsters ) since the s2 is still a formidable force and has loads of dev support it seems like a good idea, so this is what I wanted to know.
He is selling it because he gets poor battery life, I feel he has not optimized it right, and in right hands will do well, what is the average you guys get? I'm happy with a day (That's what I get currently on my current phone)
The phone has suffered a strong fall once on a tiled surface, this was more than 6 months ago but the only damage was a cracked screen, the touch response is perfectly fine, there's only a crack on the screen. He will fix it and sell it.
What else should I look out for? He is giving me the phone for a day to check out and use, so I wanna know what all should I check thoroughly, so that I don't buy a lemon , like issues facing the I9100, the screen discoloration, wifi strength, gps,overheating or any other issues I should know about and can be detected. (I got burned once buying a used xperia x10 which used to overheat and restart all the time! was barely even usable!) also any issues facing the early batches, any diagnostics that should be run etc...
Just asking because I'm curious and want to make an informed decision. don't wanna end up with a dud!
Thanks in advance!
Make sure it boots up and and it can take your sim card as it could be network locked , if this be the case unlock apps are on market and within this forum..
Check battery chack phone charges ok. Like anything have a play before you take up their offer..
Check whether the following:
1.Simcard slot
2.Memory card slot
3.all physical buttons
look out for:
1.scratch in camera lens.
2.condition of usb port and headphone jack.
you can leave out the software as it will be ok with a new flash, anyway check the working of all sensors by using some apps from market.

Regarding network lock it is not locked because I'm in india and the phone is from the UK and he has been using it perfectly. One question, how many water indicators are there? just in case I need to check? The usb port doesn't have a cover so it remains open so that's a concern.
@bala_gamer I see you had the same phone as I do now, and I'm contemplating a similar move!
any stress test apps I can run to see if all is ok under pressure?

Battery life - you're right, optimally configured SGS2s go a long way - mine will last through a day with 50-60% left over with 2 email accounts syncing (nothing else though, no Facebook, Twitter etc)
The battery life is absolutely not a problem if it's a day you're aiming for.
Problems:
Most if not all cameras have a pink spot in the centre - I don't mind it, but you can see it.
Yellowish left side of display - I have this, it's quite distracting sometimes. However, this was fixed up by the latest kernels, which balance it out a bit better. Mine is also a phone from the UK from 8 months ago, so its safe to assume this will be a problem as well, given the frequency of the problem. Not really an issue for me though with later kernels.
CM9 - ICS will be late to the party on the SGS2 because of closed source drivers - if that's a problem, get a different phone because thats unlikely to change anytime soon!
There aren't really any other problems which I can think of - its a thoroughly good phone!

Thanks man appreciate it, been reading up on the threads here and saw the major things afflicting it are the banding issue, the pink spot, the display faults... anything else?oh and what is the approx cost of replacing the cracked screen? Anyone from india can let me know?
Bump! Guys anyone knows how much a screen replacement is? Anyone from India perhaps?
Oh and guys the camera glass cover has some tiny scratches around it, nothing major but it does have a few, not too deep, but visible, will this have an effect on the quality? Because I couldn't notice anything in the pictures taken, but would like it to be at its best!
Hey XDA!
I'm having an issue with my Galaxy S2 I9100. Basically the problem started a while ago when I dropped it and the screen shattered. I wasn't willing to get the screen replaced so I bought a replacement screen off of eBay and replaced it myself. At first it seemed to be in complete working order and everything was going great. However, over time I got an issue of the phone turning off and me having to restart it. It would come at the most random times too, I would be going about my business and the phone just randomly turned off. The problem progressed and got worse and worse and the shut downs would be more frequent. I remedied the problem by keeping the phone plugged into the A/C adapter and it wouldn't shut down while it was charging. It got worse however, and I could barely turn on the phone without it completely shutting down after a few seconds, and even when it was charging it would still turn off. So basically my question is how can I fix this? Is it a hardware problem and something that I shouldn't try to fix because its not worth it? I tried even resetting the phone to factory settings and everything I had in my knowledge to fix it but nothing would work. Would it be just worth it to sell it as spares? Thanks for helping me out!
That sound like the battery is dying, not the device.

Allright, the battery seems to have expanded a bit as well I should note, so that may be causing the problem. I have a friend with the same phone so I'll try his battery to see if it makes a difference.
Swap it & share the outcome with us.

Battery expansion is a sure sign that the battery needs replacing, and the other symptoms you describe are common to a failed battery too........
If the battery has expanded, that is an indication of a build up of gasses within the cell.....the battery is now pressurised....it could physically fail at any time....best to take it out and throw it away before it leaks fluid all over the inside of your phone. Further charging will only serve to increase the risk of failure.

Oh god I feel so stupid now lol. Yeah I tried it with another battery and the phone works completely fine nothing wrong with it. I guess I'm gonna order a replacement battery off of eBay tonight and sell my phone once it arrives. Thanks so much guys! :good:
Just for future reference however, how is the battery expansion caused and what are some ways to prevent it? Thanks again.
'Old age'. You can't. When the battery begins to expand & feel 'squishy', it's time for a new one.
Hi, although I've been reading around the forums for like a year now, this is my first post.
----------Story:
Recently (about a month ago) I started to notice a dark smudge on my phone's display. Its very light and hard to see, but when I notice it (often) its very bothersome. Its like half an inch from the right, right in the middle. I googled about it for a while, and apparently it has to do with the amount of pressure applied to the glass. This was hard to believe to me, because I take care of my phone like if it was a baby.
Anyways, being bummed about it. I move on living. And just in my daily phone use, i decide to take off the battery cover for a reason I can't remember, I did this with the display on, and I noticed that while I was lifting the battery cover, the smudge area of the display started to glow in colors, like when you apply too much pressure on the glass. And this got me curious. I started pressing different parts of the phone, and noticed that the smudge area goes crazy when i press right under the capacitive buttons. And the plastic frame on said area. After this I did bought the story about the display being damaged by too much pressure. Anyways, everything changed just a few minutes ago.
I was trying to free up the most RAM possible, so, looking around on the settings, i got into developer options and accidentally got curious and messed with something that froze the phone. I decide to take out the battery, and I find myself again with the battery sorta.. Sticking out a little, like when you lift the battery to take it off but not completely. This is something I had noticed months ago, maybe last April or May. Well since it really bothered me because the battery just wouldnt go all the way in, i decide to inspect it. And note that i have done that before, the first time i tought that it was normal, the second time i tought that it was the shape of the phone. But today it hit me. Thats not normal! The battery is bigger. Like, right in the middle, the battery has a litte bump on both sides, like when you bake a cake and it grows, well, a bump just like that. But its hard to seem really hard to see. But somehow I could feel it in the hand, and I decided to put it on a flat surface and it is indeed true. The 4 corners don't touch the surface at the same time, not even pushing it down. And I remember it used to back when I bought the phone a year ago.
And that's not all, the worse part is, that I realized that the bump of the battery aligns perfectly with the smudge on the display. So it must be it!! The battery applied pressure from underneath, causing the display to touch the glass. And as i checked around the phone, turns out that the glass is slighly getting detached from the lower area (battery area).
Maybe it wasn't my fault, but I feel so guilty for not noticing earlier. I'm really worried, as I have very poor battery life, and I fear the display getting damaged even further. Oh, and also. I noticed that all the issues I saw on Google about the smudge on the display, are in the middle, half an inch from the bottom just like mine. What if its the same battery problem?
-------- question:
Is that really whats going on? And what should i do to resolve this problem?
I was really paranoic the moment I realized that the battery was messing up the display. So I rushed here looking for help. Thanks in advance.
My device is an HTC EVO 3D, (VM), Running CM 10.1 WFTN, and the battery is stock.
I Think You have to go to the Maintenance .. Since Its Not A Software Problem the phone should be taken to a technician .
I Hope They Will solve your problem there & Your Phone Would Work Again . :good:
You should replace the battery before it cause any more problems.
this kind of stuff usually happens then the batteries are overheated or overcharged multiple times. do you leave the phone charging overnight? or maybe using a cover which acts as insulation.
Fixed!

Yes. I have my charger plugged almost 24/7 because of the poor battery life, and I let it overnight all the time. And yeah the phone gets very hot when I use tethering or any graphic intensive game for a long time. (Which is often). I think I overuse this phone.
And the cover is just a Trident Perseus (siliccone).
Anyways, i will replace the battery soon, since i found that with the battery cover removed, the smudge goes away. i assume that the battery being forced in by the back cover, causes the battery to apply pressure to the display from the inside, making it touch the glass which causes the smudge. For now i will use my phone with the back cover a little open on the bottom so the battery doesnt get pressed in. While i get myself some replacement batteries. As soon as i get the battery replacement ill say how it goes. I needed the raplacement anyways. I only get up to 6 hours of battery life, and thats changing the governor to powersave. Which is obviosly not good. I guess the battery just went bad.
silicone covers a bad particularly if you have heavy usage. I would recommend you always remove the cover when you play heavy games or use tethering
thanks for letting me know. i'll remove it when necessary. or maybe ill just get a non-silicone case. hopefully all this will increase the life-span of my next battery.
Hi,
My wife's been complaining about her sgs3, i9300a phone a lot lately, so I've been taking some time of to have a long hard look at it.
the phone in itself works quite well, it is somewhat guarded (she tends to drop it a lot but most of the time it's actually in it's case) and we've switched the screen once (well, not the screen, the top half of the phone to be exact)
the phone used to have a stock 4.1.3 (I think) samsung rom on it for the past year, it's been working well untill a couple of months ago I think and it does still function properly on light use
so what is the issue?
if you'll start a game, or anything that'll cause the phone to heat up - the screen would flicker a bit (not always) and the battery will suddenly report to be down to 0%, shutting down the device right after.
this sudden discharge is obviously not real, as the minute I connect it to a charger and boot up the phone it shows it's last charge before the phone was shut down - however the issue keeps on repeating itself over and over again.
If the phone is connected to a wall charger (or a pc via USB cable) this doesn't happen.
I've been trying to install a kitkat on the device (it have been working slowly so she needed an upgrade) yet the issue persists.
I've been reading around the Internet, some claim it's a faulty battery issue so I'm ordering one from eBay, however - I can't shake the feeling it might some other faulty hardware, perhaps a memory chip gone bad? as I can't see the connection between a bad battery and a flickering screen.
Truth to be told - I'm not a fan of android, or samsung, so I don't know much of the history of problems with it (if there is any) and I've been hoping that there is someone around here who might encountered (or heard) about my issue and would be able to shed some light for me.
thanks in advance!

Yeah... I'm planning on stealing my boss S3's battery for some testing later on today if he'll ever decide to show up...
perhaps shouldn't have told him that beforehand
I did hope someone encountered and fixed/learned about this problem as the device has 2 years of history at least...
if it'll come to motherboard switching I'll just force the little lady to switch to a real phone such as an HTC, or maybe go to WP
It was the battery..
Perhaps I should've guessed it by the fact it was REALLY hard closing the case... but it was only after I saw a normal battery that I noticed the real difference.
so for future reference to whomever might meet the same behavior - my battery was about 1.5 the size of what it should be and was quite round,
better call those Samsung representatives and get a replacement before it explodes
Anyone has experience with those 4200Mhz batteries? worth the money or should I just get a genuine one (it cost about the same in here, like 4$ more), the reviews are quite mixed.
