[SOLVED] SGS2 doesn't charge. - Galaxy S II Q&A, Help & Troubleshooting

Appearantly my SGS2 doesn't charge, when I connect it to the wall charger it boots up, shows that the battery is at 0% and shuts down after about a minute. Than it repeats it the process over and over again.
Any ideas?
* Solution: MicroUSB pins were dirty, cleaned and the phone charges.

did you customize your device e.g. flashed a rom/kernel?

Nothing, completely stock.

I am having the same issue. Wont charge, battery icon shows up for about 5 secs than flickers off - then repeats that every minute or so. It also gets really hot. Have tried different chargers, cleaning the contacts etc but nothing works.
It wont enter recovery or download mode either

If you are running pure stock ROM+Kernel then it sounds like a mechanical fault. Try and order a new battery in the first instance and see if that solves it. Otherwise take it back and get it replaced by the manufacturer.

It is common for this to occur when the battery has been drained past its safety net.
Leave it doing that charge loop on and off. It will stop after some time.
This a warning that you need to stop letting your battery go to 0%
Don't be lazy, charge your phone when it needs to be charged.

Just clean your micro USB port on the phone. When it's dirty it makes pins short circuits... You can use an ear swab + alcohol.

I'll need to try cleaning that microSD slot, I bought new battery, phone powers up but now it doesn't charge at all.
I plug it in, nothing happens. Any ideas?

Im not sure how I can clean the microSD slot with simply an ear swap since its such a small thing, but I cleaned it as good as I could, not I shows black screen with yellow triangle and exclamation mark.
I tried the new battery, the phone powers up, shows its charging but still stays at 0% and reboots continuesly..
* EDIT! The triangle vanished and the phone is now charging! Special thanks to radkor! It was just a dirty microUSB slot.

If you can't charge the battery using the usb slot then you could buy a standalone battery charger off ebay... This won't help if there is more problems than just the charging though.... But its fairly cheap and you now have an extra oem battery for a spare...

The phone charges now properly but both the battery go empty in less than 10hrs even though I've got Juice Defender and BatterSave mode on, also it reboots continuesly when I make a call, I think I might have another problem on my hand..

phone broke ? need help

Hi
I think my phone is a little broke,
It ran out battery last night so i put it on charge this morning.
was on charge by wall for 10 min to get some battery then swapped over to car when i was driving it turned off now when i try and charge it at work via a usb wire and cplug converter i just get the battery logo with the spining circle for a few seconds it flashes then goes off does this about 6 times then the screen just goes off and will not do anything
anyone know any fixes or has it gotta go to samsung ?
Thanks
Have you tried taking out the battery?
Please let us know if it starts working again.
tried that, its like its not getting the power it needs for thats first few seconds as the buttons at the bottom flash on then off again
With the phone OFF. Leave it charging for four hours using the supplied mains charger.
With the phone OFF do you see a picture of the battery showing how much charge you have when you plug the phone into the mains charger? How much charge does it show?
it comes up with the b attery with a circle logo init then turns off then comes back to that over and over again,
i dont have the proper charger on me just the usb wire and a plug to usb
Think getting somewhere, tried a mates battery that works fine, mates charger wont charge on my phone but will my battery in his, so i guess my micro usb port is broke :'(

Use Galaxy S2 without a battery?

Hi There, Does anyone know if it's possible to use the Galaxy S2 without a battery, or trick it into thinking it does have one and just run off power?
My phone works, but kills a battery in about 30 minutes. There's one resistor in there that gets super hot after being water damaged, but only with a battery in.
Wouldn't know where to buy a new resistor, so wouldn't mind leaving it permanently docked and run my audio for the house through it if I can somehow run it without a battery
.
I think it can run without battery but can't boot without battery

Just tried that on another S2 I have and it didn't work
Sorry to revive a old thread, but I would also like to know if there is a way to trick the phone into booting from a power supply instead of a battery. I am attempting to hardwire an old S2 into an imbedded in car media player blah blah blah.....long story short I have issues using the battery.
If I leave the phone plugged into a constant powered USB when the car is off and the phone is sitting dormant it over charges, the battery gets super hot, I get the overcharge/overheat warning etc. If I disconnect it, then I have two issues, first it loses charge as it is in use and pulling it when I park means having to bring it inside and top it off etc. The second problem is....it kind of defeats the purpose of an "embedded system".
I have the software set up perfectly and I love the way it all works. My only current hitch is the battery issue. If I can bypass it I know I can run a off delay relay, so that when the car is shut off the USB cord stays "hot" for say 1 hour then shuts off thus removing power. This option seems tedious and the parts more expensive then a simple power supply replacement. Unfortunately I do not know the software side.
I have been able to get the phone to boot without a battery, however as soon as it is done booting I get the "battery low, plug in" warning, then a few seconds later the phone shuts off........Is there a way to keep the phone from shutting down at that point, or get it to ignore the fact the "battery" is at 0%?
Edit: When I say I can get it to boot without a battery, I am wiring a power supply directly to the two pins that the battery + and - would be touching.

any solutions to this yet?
the phone has a circuit that controls power and charge level by communicating with the battery so it will always know that the battery is removed because the battery feedback circuit will not be present.
Sorry for reviving an old thread, but i have a solution that may help others out.
I have found a way to power the Galaxy S2 GT-I9100T from an external power supply ( i have also tested on S3 GT-I9300 and S5 SM-G900I).
My first step was to create a dummy battery out of perspex, you could use any non conductive material.
Make sure you include the alignment notches and keep it as close to the size of the original battery so it is a snug fit and wont accidentally fall out.
When you know the perspex fits you can start fitting the contact terminals, make sure you have the polarity correct and that they line up with the contact terminals of the original battery and the spring terminals in the phone.
Once you have the terminals fitted you can then look at powering up your phone, i used a LM2596 based DC-DC converter that i had laying around.
If you are using a variable DC-DC converter like i did make sure you adjust the output of the power supply BEFORE connecting to your phone to prevent you destroying your device.
My DC-DC converter is set at 3.88 Volts, this value seems to trick the phone into thinking it has a battery with greater than 40% charge that way you don't get the annoying low battery alerts.

How about taking your admittedly innovative idea one stage further.......
If you have an old battery laying around, why not (very carefully) remove the top part of it for use with your perspex replacement....this top section contains the overcharge protection circuit which would help to provide added protection to the device....it also has the benefits of the facts that the battery connection points are already in place and correctly aligned (it also has those alignment notches at either end).....imo, an improvement on an already good idea....
I got problem with my SGS 2 - after long on-shelf time battery drained to absoltely zero. My voltometer showed 0 on every connector. I was unable to charge or boot my phone (24h+ on charger, no signs of life). Dead, bricked, gone... Battery was relatively new (some months) so I didn't want to buy another one. Then I read Spud2233's post... and tried it .Well, kind of variation. I connected charger to phone's USB port and additional power (Motorola's dual port charger) to internal batterys connector (simly stripped old USB cable). Then battery was inserted and.... voila! After 2 or 3 retries my phone booted in and started to charge. I disconected additional power cable, phone is loading as usual. Battery revived!
Thanks for inspiration, Spud2233!

I too have had SII batteries go dead after too long, and the SII seems to be unable to power up without a voltage across the battery terminals.
I used a small variable power supply set to about 3.5 V. I trimmed some thin hookup wire until only a few strands were left and 'pinched' them between the battery terminals and the phone battery contacts. Then with a charger plugged in to the phone I was able to 'trick' the phone into turning on. Once booted the battery charged fine.
Note I think this should be done quickly as the phone and power supply will fight each other for as long as the voltage is placed on the contact, so I pulled the PS wires out (keeping the battery in) as soon as the phone was booted up.

Thank you so much for the solution to my problem! I have purchased TWO batteries already and they both stopped working after drained to zero. I was blaming a charger or a quality of the battery. I found other posts suggesting to remove a capacitor but it wasn't broken...
Thanks to you, I have just booted my phone, pulled out extra power after couple minutes and it charging on its own now! (well 5% as I speak).

I am in the same situation with SII batteries go dead after too long.
I do not understand this part
''I connected charger to phone's USB port and additional power (Motorola's dual port charger) to internal batterys connector (simly stripped old USB cable). Then battery was inserted and.... voila!''
or this part
'' I trimmed some thin hookup wire until only a few strands were left and 'pinched' them between the battery terminals and the phone battery contacts. Then with a charger plugged in to the phone I was able to 'trick' the phone into turning on.''
how is this different than inserting the battery in the phone and then connecting the usb power supply?

The phone won't charge the battery if it doesn't detect (sufficient) voltage. You can "jump start" the charging process by tricking it with a fixed voltage across the terminals.
so I take my dead battery, then
-take a usb charger+usb cable
-strip the usb cable to get two strands
-put one strand of the usb cable on the + of the battery
-put one strand of the usb cable on the - of the battery
=>the battery is charging
[or easier, I take battery like this,
put one strand of an electric cable on the +, connect this cable to the + of the phone battery, then put one strand of the electric cable on the - of the battery and the - of the phone battery
then I put the battey in the phone with usb power supply IN and the phone boots ???
I wouldn't use a USB cable, 5 V is probably too high.

Yep, that's exactly what I did (except I used a 3.5 V power supply).
Once the phone has begun booting you should probably disconnect the "jump start" battery as quickly as possible or it'll fight the charging circuit.

but you agree that connecting the phone battery the charged green battery is like charging the phone battery [at least a bit]?
then I would just use the phone battery normally, by inserting it into the phone and boot the phone and finish to charge the phone battery.

Not really, the SII battery will still be dead after a few seconds "charging". Getting the voltage across the phone battery terminals tricks the phone that there's a charged battery present so it will boot and continue charging it. Otherwise it gets stuck in something like a boot loop looking for the battery (mine did anyway).
If you could charge it separately from the phone then obviously you'd just do that.
Thank you for all your tips. I tried similar stuff, but I guess the voltage was just not right.
So I asked around to get a spare battery, which which I powered on the phone. It worked like charm.
I change the battery while the phone was running and tada! my phone was loading the "out of order" battery just fine.
Pretty much the same trick you guys did, but with less soldering and more quick magic happening ^^

I did just that to my s2 and his dead battery.
I was scared to go with ONLY a 18650 battery to charge the dead battery (no phone or usb charger involved) : I did not know if I should connect pole+ of the 18650 with pole + of dead battery (and pole - of 18650 with pole - of dead battery) which is the parallel scheme or the opposite, to go with the ''series'' scheme

You were right to be scared. You should not do that. The dead battery might draw too much current. That could be dangerous. Read a bit about how charging of Li-Ion batteries works: first you charge with constant current (CC), which depends on the battery's design, once it reaches the correct voltage (4.2 V for a single cell), it should go into constant voltage mode, and then you have to know at what time or remaining current you shut the charger off. A good rule of thumb is to wait till the current drops to 10% of the charging current. E.g. if you were charging the battery with 1 A***, you should turn off the charger when it's down to 100 mA.
***1 A is just an example that would work for most modern phone batteries. However, this can be different! Ideally it's written on the battery.
Also, it's very well possible that in newer phones the battery will only output voltage if the charging circuit inside the phone allows it to. At least that's the case in notebooks for many years, and I don't see why it should be very different for phones.

Phone gets very hot, even when it's turned off

Hello,My brother gave me an old Galaxy SII that he had stored somewhere, but when I insert the battery, (even if it's turned off) it gets hot on its bottom right side. (seeing it from the back, see the attached picture below) and when I plug it to a charger it gets super hot (I can't stand to put my finger on it )from that same side, and some seconds later the "Charging paused, battery temp too high or too low" sign will appear. The same happens when charging it while it's turned off.
Any suggestions? I put my dad's battery on it(a SGII too), and the same, and put my battery on his phone and it charged fine, so I don't think that the battery is the problem. My guess is that the charging port is faulty, I tried to clean it with isopropyl alcohol and a toothpick, but no luck.
Do you think that if I change the usb part will fix the problem?
Any suggestions?
By the way, I'm on stock samsung GB rom, and I already tried a Hard Reset.
Greetings.
Yeah you might as well try replacing the port/flex cable, but the getting super hot thing is a worry. Could be the charging circuitry. Get a port/flex cable from eBay/wherever & see how it goes.
That's a short man, take it to service center and they'll check it out.
Yeah, I Think that it's a short, because even if the phone it's unplugged and powered off, when the battery is inserted it gets hot.
I found this, http://forum.gsmhosting.com/vbb/f258/samsung-galaxy-s2-i9100-short-circuit-solution-1537757/ I'm going to open it and see wich component get's hot,

Galaxy SII showing charging screen when trying to boot, unplugged from charger.

The phone is unrooted. And as the title says, whenever I try to boot the phone it goes to the charging screen. The phone is unplugged, though.
Then the following happens: it loads the battery data, battery is shown how charged it is, the dots at the bottom turn on and off one after another, at the 3rd dot, the phone turns off. Repeat.
The only way of turning my phone on is trying to put the charger in and hope to god it recognizes it, really charging it and thus making me able to boot up. Or I've to push Volume Down + Home + Power and then cancel (making the phone restart itself), which does boot up the phone correctly for some reason.
I've turned battery percentage on in the statusbar at the top of the phone, and sometimes it keeps saying unplug the charger when at 100%, so I do and it keeps saying that for 15-30 minutes after. Then I try to restart the phone (not turn off and on) and then the battery dropped to 60-80%?
Finally, when the battery is "fully charged" the screen is flickering until I pull the charger out.
What I've tried so far: rebooting, turning it off and on, pulling the battery out and putting it back in, trying a different battery.
What I'm still planning on doing: Restocking the phone through Odin, or bring it to a repair service but I would try to hold off to that.
Has anyone experienced this before and how do I fix it?

Yes, it looks like number 6 is my problem. I will thoroughly clean my phone when I'm back home. Question: the "USB PCB", is that the end of the charger you plug in the usb port?

Phone doesn't turn on or charge with empty battery

My phone's battery just died while charging. No idea how it happened, but apparently it wasn't charging at all, even though it displayed a charging icon.
Now it's turned off and it won't charge. When I plug it in, it turns on, displays the screen with the big battery, as usual, but only for a few short seconds. Then it turns itself on, even though it has no power, and shuts itself down immediately after it turns on, meaning it never charges. Then it goes t the big battery screen again, then turns itself on etc. and this goes in a circle for all eternity.
What do I do? I have no battery charger and I don't have any friends with a SGS3
(I'm running UltimaROM 17.1, in case that's related, which it might be, since I jut flashed it yesterday morning.)

You say you plug it and this happens? But what do you plug in when you wrote this: "I have no battery charger and.." ?
The battery could be dead or maybe it is also the dock connector! I don't know. FIrst buy a new battery. It's not a big deal
Or you try to search for someone who has an S3 and try it out
Good luck!
I meant I have a charger for my phone, like with a USB cable, but I don't own a charger that only charges batteries. Thanks for the quick reply, but I fixed it already. It wouldn't boot to recovery because the battery was completely empty, but with some fast finger-work I managed to plug it in and get it to boot to recovery before the battery screen. Since recovery doesn't use up battery as much, it started charging without shutting down and it's fine now
