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.

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..
Yesterday I let my phone die (low battery > powering down) and it stayed dead for 30 or so minutes. I plugged it into my wall charger and nothing happened. It didn't boot up, and there was no LED light.
I plugged it into USB and got a WHITE light, but it didn't charge. Even if I remove the battery I still get the white light when it's on USB.
I tried leaving my phone on the wall charger overnight, nothing happened.
I left it on USB for 4 hours, still nothing happened.
To sum it up:
Plug it into wall charger: Nothing happens, no LED
Plug it into wall charger with battery in: White LED
Plug it into wall charger with battery out: White LED
Nothing will charge it. I tried 2 USB cables and 3 wall chargers. I know they all work because I also used them to charge my replacement phone.
Returning to Sprint is NOT an option (I live in Canada)
What can I do to fix this?? The phone is less than 2 months old

Your battery has been drained out completely.so you will need to boost up your battery.either connect your battery to a compatible battery charger or do following step
take one of your usb cable and cut it. you will get four wires. you will need red wire and black wire. Take out the photon's battery and connect the red wire to (+)positive terminal and black wire to (-)negative terminal of the battery as indicated on the battery.now connect it to your wall charger and let it charge for 15-20 min and after charging insert the battery in your photon and charge like normal.
Huge thanks! Worked great, my Photon is back up and running! I stripped the cable I had from an old audio player and connected it like you said (the (+) and (-) are the outermost terminals).
I'm going to invest in a standalone wall charger for the battery now, as well as tell Tasker to turn off my phone at a reasonable 10% battery so it doesn't completely die.
Thanks again for the help!

Proud that it helped..
But remember not to overcharge your battery with this method this is only for boosting the battery. don't charge for more than 15-20 min.
having a very similar problem as op but...
Hey wuddup fellas,
I'm a long time lurker, first time poster. Well, never really had to until now. Anyways, Im having a VERY similar problem as the OP but with the difference that my white LED only comes on for a short amount of time when connected via usb, maybe a couple mins max. Not to mention, for some reason, the white LED only comes on when connected to a specific usb port... I got 3 on my laptop (1 on left, 2 on right) and it only comes on when attached to the 1 on the left.
Lead up to failure: I was on texting when the 5% low battery pop up showed itself. I usually get 10mins before it dies so I didnt sweat it. Then, a few mins later it died. Ok, np, I'll just connect the charger wait a sec and we'll be good to go... Guess again, when I plugged in the charger, the charging indicator didnt come on, which I thought weird. Maybe its super dead, I'll just wait a few mins and it should be able to turn on... Nope, nada. So, I pop in the extra battery I got... Same thing happens to that one! Now I'm at a loss.
I read a few forum posts around the interwebs that sound along the same lines of whats going on with my phone. This post turns out to be the closest, so I try and jump start my batteries... Again, nada. Another post says I need to charge the battery out of the phone. So, I Amazon a standalone charger for the batteries. Throw one on the new charger, battery is completely dead, takes a few hours for it to charge. Throw the newly charged battery in the phone... nothing. Charge and throw the 2nd one in... Again, NOTHING!
Now the white led wont come on anymore. Which I guess it wouldnt need to cause the batteries are fully charged. But now I got no clue where to go... please if someone has any insight, i'd greatly appreciate it.
I can only charge from the car charger a very old laptop and by computer if a hdmi monitor is pluged in to the photon.
The laptop has a dead cmos battery so it sites at the hit F1.

Sorry to wake up this thread, but I'm having a similar problem and tried the wire method. When I plug into the computer I get the same white light, but I also get the white light when I plug into the wall. After trying with the wire, I plugged into the computer and pressed the power button. The light turned green, but the screen still didn't come on.
do you have spare battery from any other mobile.just take it and connect two wire + and - to the spare battery then other end to the photon phone pins using crocodile clips with same + and - symbol just double check before connecting don't connect reverse only connect to two pins then try to turn on and post your reply..
Motorola Photon Q, Dead. Fixed easy
I did as some suggested above, but without removing the battery. After removing the back, I just unscrewed the (+) and (-) screws on the battery, lifted up the battery tab, then clipped small alligator jumpers directly onto the battery tabs. I connected a power source of 4.35v until the battery read 3.77v, then removed the power. Then I started charging it with the standard wall charger and it powered up -- now working great.
So last night before I went to sleep, my NT had about 40% battery life left in it. I'm currently running the final alpha build of CM7. I've been experiencing really bad wifi loss issues and have kept the 'Never' option enabled under the wifi sleep policy (thinking that would help hold the connection).
I woke up to find the NT was turned off. Figured that was odd as I was only asleep for about 5hrs. I turned it on and then noticed it got into the OS and then died. I did see the battery icon was red briefly.
I then plugged it into the wall and it was boot looping. I saw the 'n' logo pop up, screen went black, 'n' logo, etc. etc.
After numerous attempts of holding down the power button for 20+ seconds, holding power+vol down for 10 seconds, plugging it with or without an sd card into the wall and computer, nothing is happening.
The computer does see something as I'm hearing the common connected/disconnected tone from the USB port. Now I'm noticing that plugged into the wall, the 'n' on the cable stays orange. It never turns green.
Did it go 'poof' in the night somehow?
[EDIT] Ok after leaving it plugged into the wall for about 15mins, it suddenly turned on but had a google framework FC error. Yeah, not sure what I should do at this point. It appears to be charging...
It's been noted by others that if the power level goes below 15% you mustn't turn the device off if you don't have the original charger nearby. If it dies you need to charge it with the original charger for a bit before it'll power back up.
I assume this means that you can't run it off the cable while you've got a completely dead battery. That kind of stinks but isn't too surprising, a lot of devices are like that.
So does that mean that if the device is <40% of battery I need to plug it in if I won't be around it for a while? Not sure I'm cool with that. Battery life was great all day yesterday but somehow it dropped 40% in under 5hrs while asleep.
I can't really say much as I haven't dealt with it personally. People were talking about it in a couple threads about the NT's charger and unique 12 pin cable.
Here's what I understand from what I've read:
You can run it until it's empty all you like. You'll just need to use the Nook's factory charger (or a compatible 2A charger with bridged D- and D+ pins) AND (this is the important one) the factory USB cable to charge it.
If you run it until it dies you have to charge it for a little while before it'll turn on again, BUT you have to use the original cord and charger. It won't charge off of a regular micro USB cable nor will it work if you're using a 2A or smaller charger that doesn't have the middle two pins bridges (the Apple UBS chargers won't work nor will your PC's USB ports, for example).
The NT will charge, albeit slowly, if connected with a third party cable or USB charger (without the data lines D- and D+ bridged), but not if the device's power has been depleted.
So I suspect something sucked up a lot of juice while you weren't using your NT. Not a huge deal, but definitely annoying. Plug it in for 15 minutes and you can get rolling again.... BUT only if you're using the original charger and cable. Lovely isn't it? It's not a huge problem but it is annoying. I wish you could at least use the device with a dead battery while plugged in.
I just mention the charger/stock cable thing because I'm sure someone will probably see this post in the future and may be having that particular problem resuscitating their NT.
Cool, yeah I don't specifically set out to run it down to zero but since the device is clean with minimal stuff running in the background, it's difficult to know when this might happen again. I assumed I'd wake up with like 20-25% battery left. The framework FC is also something I'm concerned about but maybe it was just a fluke.
Ah well, really do appreciate your input and I'll be sure to keep the stock cable/adapter on hand when I'm on the go.
Battery showed fully charged, I rebooted to do another CWM backup and then when it came back up it showed 84% charged. Lol. And this pic made me laugh even more. Time to get that lady from Poltergeist involved I think...
The Google Framework force close is typical of stock rooted NTs. I don't believe it ever did any harm to anything though. Just that it sometimes appears on reboot.
I'll ask one additional question as to not make another topic since it's related.
Opinions on battery calibration with the NT? That was one of the reasons I didn't charge it last night as I wanted to fully run it down and then fully charge it back up. Does the NT require this with a new rom install? That pic above shows the battery gauge clearly wasn't correct initially.
Your battery is draining overnight because wifi is running the whole time (as you stated in your first post).

That's what I obviously thought of at first but it didn't drain nearly as much when I was using it throughout the day. The only thing I can think of is maybe the fuel gauge itself was wrong from the start, which refers back to my calibration question.
My GS2 has the sleep policy set to 'Never' as well and only loses maybe 7-8% after being asleep for around 7-8hrs and it certainly uses more juice in sleep due to the cell communication, etc.
Ever since sometime yesterday or something. My phone has been steadily discharging whilst plugged in.
I charged my phone to full yesterday and noticed that it was charging a bit slowly.. but eventually it got there.
Then I unplugged it and plugged in a really low battery (4%) to charge it to full overnight (I have 2 batteries)
I woke up to the phone at 26% after an entire night of charging (about 8 hours).
I thought that the battery must be dead. It's a cheap one from Ebay but it has the official sticker on it, but it's a bit creased so it looks like it could be a cheaper one with a fake sticker on it. It always used to last about 20% less than the original one I got with the phone anyway. But that isn't the point.
I thought it must be dead. But I charged it a little before work and nope, it just kept dying. So I started worrying if the charger had died.
Then I just swapped the battery out and decided to use the fully charged one.
After about a days use I went to plug it in and it ALSO started discharging whilst being plugged in.
In fact they seem to discharge FASTER if plugged in.
I immediately thought that the little Wall Socket to USB Adapter had just blown. So I unplugged it and just plugged the phone in via my PC's USB 2.0 Port.. Same thing.. it sits on the same Percentage (%) and then gradually (if I use it at all) it starts to discharge.
It's charging so slowly that if I use it at the same time it'll die. When before I could even have a Skype call and keep it plugged in and it would overcharge through the amount of power I was using.
Does anyone have any ideas? It can't be the battery because both of them are dying no matter one, and they can't have both died. It might not be the little USB charger (although it no longer gets hot like it used to) because if I plug the phone straight into a USB port on my PC (I know the mW is lower but it should still prove if the charger is dead or not) then it still discharges.
Any ideas? I mean... it looks like somehow the USB port is no longer taking a charge? Without my phone I am a dead man.. it will totally mess up my work and everything...
Have you used a different cable? You said you plugged it into your PC USB port but you didn't say with which cable.
I don't have another cable :/ as it's a proprietary one... I can't just use some normal micro USB..
9/10 it's the cable that's the fault.
It's not proprietary. I walked into a shop and said "2 micro USB cables please" and they both work better. Also my HTC and blackberry micro USB cables both work better. Try another cable. Borrow one if you have to

I have a micro USB cable.. it's for my HDD and it doesn't fit. It's a little bit too big. The last HDD I had too was the same, just a bit too big. Maybe it's not proprietary but I'm pretty sure it's smaller than the traditional Micro USB.
Also, I tried doing a file copy from the phone to my PC and back and forth. The speed is totally fine, really fast.
So could it still really be the phone? I'm a pessimist and I don't see why the cable would just suddenly die... I've already had my phone replaced on one of the 'sudden death' issues like everyone else. I wouldn't be surprised if there's yet another hardware fault...
At the moment it's off, and charging from the wall.
EDIT: Maybe it's a Mini-USB not a Micro.. in that case I have 1 Micro USB. Still I think my phone just died somehow overnight................. again.

what? yes you can
Well cables are expensive in Finland but I suppose I have no choice but to bike down into town and buy another cable...

no, your phone uses a traditional micro USB. and data speed is not really connected to charging speed
New cord seems to have fixed it. 'Hama' brand (Finnish) triple shielded, with some gold plated connectors. Looks a lot higher quality than the traditional Samsung one. (Unshielded, no gold plating)
Also it's a bit longer, which I dunno if that will affect the rate of current. I know that shorter is better. It's 1.8m vs the older 1m.
Seems to be charging properly now, still a bit slow (phone is off) but I suppose that could just be the battery getting used to actually receiving a proper current finally.
Christ and I almost went and just bought an iPhone...
If in the end it was just the cord then €12.95 bought me peace of mind.
EDIT: Scratch that
It won't charge if the phone is on at the same time... it just sits at the same level of power. But if I use it, yeah it starts to discharge.
So basically it's lost the ability to charge whilst being used, and on top of that it did charge pretty slowly when turned off, but at least it did.
Looks like I'm going to have to sort out a way to fix it, then maybe sell it and get something else. I can't handle a phone that's such a disappointment.
The Galaxy S2 was a bit of a let down, to RMAs to Samsung now...

sounds like something Monster cables would sell
Shame that it doesn't seem to have done the trick.
I'm really confused now. The battery I got off the net doesn't seem to be charging really at all, but ever so slowly when the phone is off.
The other battery, my normal OEM one charged sorta slowly but kinda normally I guess..
Really don't know what on earth is going on. It's going to be a total pain to get this thing repaired a second time, and it's been rooted and flashed multiple times. Plus it has the new bootloader on it that you can't possibly trick that it's been rooted.. (was installed after a fix on warranty)
So the oem battery charges normally?

of course you can, use TA
You may have a faulty charging port (if not battery problem)
Why not download the Galaxy Charging Current app and see if your SIII is charging at 1000mA using wall charger?

BTW - Other than faulty charge cable, it could also be faulty wall charger

Thanks so much for the app. I bought the pro seeing as it's only 0.50c
Now this is really confusing. I'm gonna do some testing now:
On the cheaper battery Ebay Battery Using New 1.8m Shielded Cable With the OEM Wall Charger
If I plug the cord straight in from the wall charger without moving it the power starts off at 1000, then goes down to about 900, then after awhile to about 400, and then after awhile longer to 100. But I can't be sure that I am not bumping the cord even a tiny bit. Also the battery is at 94% so it could just be shutting off the charge in order to not overcharge. (Though before the issue the batteries always charged to 100%).
If I move the cord around and tap refresh the number drops by 100 - 200 every time I press refresh (all the way down to 100). Also if I move the cord perfectly back into the middle, the number doesn't go back up. It's like the more I move the cord around the lower the charge will be. If I leave the phone alone for a bit and look at it again after a minute, the rate has gone back up to 1000, then down to 900. Where it seems to stay.
The statusbar battery app shows that it is charging too (% is going up as normal)
At 97% charged on the cheap battery the phone only accepts a maximum current of 300. So it seems that the overcharge protection is working.
Though the battery can display fully charged and then drop to 97% after I unplug the cord. Which didn't happen before but it's an understandable thing.
Summery:
Moving the cord a lot causes the rate to drop dramatically.
When plugged in the current starts off at a full 1000, then drops to 900 (dunno if this is normal) so it seems to start off charging at max
The max concurrent, current that can be achieved from the wall charger with new shielded cable is 900-100 it seems.
The phone seems to discharge faster when plugged in (and current on 100) than when it's unplugged??!
Could someone please install the free app (Galaxy Charging Current), who isn't experiencing issues like me and wiggle their cord around and see if the rate drops too? I want to know if there's some sort of methodology that if the cord is moved around a lot the current rate is dropped, and it won't return to normal. Or if it's just my phone. Thanks so much!
====================================================================
Ok... tested with everything I could honestly think of. Ebay/OEM Battery, Both OEM/New Cord and USB/Wall chargers and etc,
Basically it's like this. Both cords are fine. Both charge the phone just as fast. Using the wall charger is faster than using a USB. (But not if the cord has wiggled so much that the rate has dropped lower than what as USB gives)
The current rate only drops when the cord is moved, and here is the crucial thing:
When the cord is moved the rate drops anywhere from 100 all the way to 900. Meaning that the rate of charge can go from 1000 (max) down to 100 (absolutely nothing). Either in 1 go, or in bits every time the cord moves. Also if the cord moves EVEN ONCE, even the smallest bit the rate can just drop on its own.
So basically it seems that somehow there charging port has been damaged or something and the pins are no longer connecting and the phone or charger or SOMETHING has this incredibly bloody stupid thing where if the cord moves or if the rate drops, it doesn't go back up. So if the rate drops all the way to 100, it won't increase or go back to normal after a certain amount of time.
Or maybe I am wrong.. because if I push the cord even a little towards the back of the phone the charging light goes off completely, and the rate hits 0. Whereas if I pull it towards the front of the phone, the rate stays constant (at max) but if I take my hand off it, the rate drops to about halfway or really low. It just seems like the little connectors inside the phone are really.. really flimsy and loose. It obviously got damaged somehow. Either by constant connecting and disconnecting or bending or just you name it.
So does anyone have any suggestions? I might try and clean the inside of it with nail polish remover or something in case they're just dirty but I doubt it will do much. It seems definitely like the plug just doesn't fit in and connect well enough any more and that's where the power is being lost. It's gotten a bit loose, but really nothing out of the ordinary.
I can confirm that putting it in such a position where there is absolutely no chance for the cord to move at all, allows the phone to receive a constant rate of the highest possible charge.
I guess I could try and make the fit a bit more snug myself but it would be only really temporary.
I think I just need to get it serviced again, but I am not sure that I could because it's got a custom rom, it's rooted and it's already been repaired for one of those 'sudden death' issues already...
How generous is Samsung with their warranties?
Either way this is a terrible blow for me, I need my phone to pay my bills and stay connected with my work and friends. If I can't have it plugged in and still be able to move it around and use it. Then it's basically useless.
At least for now it seems to be charging okay just sitting completely still on the table.

I am having the same issue as you, I have been managing to get it charged using my ipad charger which is stronger but it sometimes still doesn't charge with that. Last night I put it on charge and it turned off due to dead battery in the middle of the night. Did you manage to fix this?

Since no one replied with a solution I will let you know my fix. I sent it to Samsung for repair under warranty and they have fixed the issue. It is due back tomorrow. Just so anyone else having this issue knows its covered under warranty.
I've got the same issue. At first i thought it was the custom ROM acting up. But even after unrooting it and going back to the stock firmware its still the same. The only way i can charge my phone is by switching it off nd plugging it in. Cuz no matter what i try, if the phone is switched on,the battery still drains. Couple of my friends had the same issue too.They ended up buying new phones. Guess this is a standard fault with all Samsung phones. If anyone's got a fix,do pass it on.

I´m having the same problem. I flashed my S3 i9300 to a cianogenmod 11 ROM. It's a relief to know it's not the ROM. The technical service prom the phone companies here really suck, so i'm taking my S3 to a third party cellphone technician and tell you if he solved my problem.
try this.
dear poster I have a solution that may work for you ,first thing take the battery out of the phone and leaving the battery out plug the charger in .leave it that way for about an hour .then unplug phone pop battery in turn the phone on .the replug the charger while the phone is still on and see if it charges better .
Hello people, i have a Xiaomi Redmi Note 4 there with the MTK processor. I replaced the complete LCD screen unit as it had the glass broken. We also accidentally destroyed/puntured the stock battery in this process, as it was very tightly glued in and we could not get it out at first. Tool was to sharp. So we ordered a replacement BN-41 Battery out of AliExpress, in a time when non were widely available.
Now the replacement battery is already in the phone, but it wont start-up with it. Despite it reads of 3.87V at its pins. Its rated at 3.85V typical. When i plug in the wall charger, the phone is starting but stuck in a bootloop.
I can access the fastboot mode with the charger plugged, but even when i let it sit there for hours, as soon as i unplug the charger, the phone shuts down immediatley. Also, when i unplug the battery cable from the mainboard while the phone boots or stays in fastboot mode, there is no change in behavior. So it does not matter if the battery is connected to the mainboard or not - same behavior. This leads me to believe the battery is not getting used be the phone.
So i measured the pins at the mainboard where the battery is plugged in, and it reads ~4.2V when i plug in a charger...
So energy is reaching this connection point from the wall charger but its not transfered into the battery, nor does the battery transfer its energy back into the mainboard - even when physically connected.
What is the issue here? Battery dead/fake? It looks a bit different than the stock battery. I read the stock battery has electronics in it that regulates charge/dischharge?
Thanks alot for any information or guesses....
Allright i tried the unbelievable... when i connect the battery connector a 180° turned, it powers on even without charger, but still stuck to that bootloop. I can access fastboot, but not recovery mode...
Fastboot mode on charger loads up battery - voltage increases.
Do you think the Mainboard could be fried because they mixed up polarity on the battery?
