My SGSII has developed an issue over night.
When I unplugged the charger this morning it stayed as being on charge and the Battery 100% symbol. It randomly flashed up as charging 3 times in a couple of seconds. It can be fine for anywhere between 5minutes and a few hours and then states on charge again.
I have taken the handset appart and can see no liquid damage and the solder on the micro usb port are all good (no dry joints etc) I gave it all a good clean down with IPA.
Since this morning it has done it several times but seems after the battery drops below 90% it no longer does it.
Any ideas on what to check next? known charging issue? possible battery issue?
Please clean your usb port on the phone using canned air or a dry brush. It's mostly a problem with the contacts short-circuiting!

Tried, also used IPA to make sure no residue is on the contacts.
It's strange it hasn't done it after the battery dropped below 90%. If it was a short it'd be doing it all the time.
Hey guys!
I have a weird issue with my phone, and after doing a bit of research I got a bit pessimistic, so here it is:
When I unplug my phone from the charger, the phone stays in "charging" state, which means the charging icon is there, the battery stats are not shown correctly, I can't plug it into my PC via USB, etc. It also doesn't enter deep sleep, since there is a vbus_present wakelock held, which is normal for charging.
I've read that water damage can be one of the causes, and if I think of it, I did have my phone with me, while I took a long bath. While the phone didn't touch any water, the air humidity was really high , so I could blame this for the issue.
Do you have any suggestions / ideas?
Thanks!
Hello?
My phone is dying here!
Sounds like water damage to me... however sometimes, to my knowledge, the issue can be solved like the fuel_alerted wakelocks: pull battery for a while and reinsert. But I assume you already tried that, so water damage would be my best guess although air humidity shouldn't cause that...
It is the same for me when I dropped my phone into water. However, it is now normal again ( lucky me). For your case, I think it water damaged, I would suggest you dry your phone. Take out the battery, dont use phone for some hour(4-5hrs in my case), dry the phone by whatever you can( I just put in under the sun for 15mins, and put it in a bag of rice). It was 2 days since I got the problem, but now its ok. Just try it.
Hope it helps
P/s: still get some minor problem but I can bear with it though
Fixed ?
Hi,
It seams a bit too laste to answer, but it might help someone esle.
I had quite the same issue, and it seams that the solution is to clean the phone USB slot with a toothbrush...
cant post the reference url cause i'm new... so search for "galaxy s2 won't turned off"...
VBUS present wakelock caused by using Apple compatible charger
It does not look like this was ever resolved, so figured I would chime in since I have been looking at this for a while.
If you use a charger which is compatible with Apple products, it will cause the vbus_present wakelock since Apple does not adhere to USB standards and requires two of the pins to be bridged or open (can't remember which) to work for their products. However, when you charge a device that does adhere to USB standards with one of these chargers, it will cause the wakelock (on all the samsung phones I have seen, anyway).
Another downside to using an apple compatible charger is that you can never get more than 500ma out of it due to the non-standard USB connection, even if the charger is capable of 2000ma output. So you get slower charging.
When you are connected to any charger, this wakelock will be present. If you use an Apple compatible charger, it will persist after you unplug it and will drain your battery around 10% per hour since it prevents it from going into deep sleep. You can clear the wakelock by rebooting the phone or plugging it into a standard USB charger, such as a PC or Samsung charger, even for a few seconds.
You can use Better Battery Stats to see the effects of this wakelock. Note that it can take a few minutes to show up once you have unplugged from the apple charger.
Yes, this really p*sses me off. This is one of the reasons I no longer have any Apple products in my house and long since thrown away all the Apple compatible wall chargers I once had. It still comes back to bite me since I still have a couple of chargers that contain batteries to charge when you are away from a wall outlet and they both cause this. When I use them I just have to make sure I reboot afterward. The USB outlet I have installed behind the stereo in my car also causes this wakelock. I have one to replace it but have not gotten around to removing the stereo to do this yet.
The next best solution to never using an apple compatible charger at this point would be to have a kernel that addresses this and removes the wakelock after it is unplugged but I don't see this happening.
Man, I know you love your S II, but don't go taking a bath with it!
Was this recent? why don't you give the little guy a rest and leave it a day in rice, stucked inside a zip lock bag, can't hurt.
Googled this "vbus_present android battery not plugged in"
found this thread. Seems to have worked for me by simply rebooting. thx!
So, to start this off my rezound fell into a pool with me. Rushed and did the usual steps for drying it out and all that. The battery was the only thing that took water damage according to the sensor. So I bought a new one and it won't charge the battery. The one time I got the phone on it read 0% charged after sitting for 6 hours. Now it's either blinking orange or staying orange for around 5 seconds. Is there anything I can do?

Sounds like your phone is damaged, the old battery was probably fine, the water indicator is there to let Verizon know the phone had water damage when people try to warranty them...
I'd throw it in a bag of rice a little longer, see if there's any more moisture stuck in it, otherwise it's time for a new phone...
I had a similar situation, minus the water, but you might try pulling the battery out and charging it manually with a power supply set to supply 5 V and current limited to 1 A. Let it charge like that for 20 min and try putting it in the phone again. If it still will not work, then it could be that the leads on the phone that connect to the battery are corroded and need to be cleaned.

How would I go about doing this?

I take that to mean you don't have access to a variable voltage power supply. Not a problem, but it would help if you at least have access to a voltmeter or multimeter. You would need to plug in your charger with cable and test each of the leads to see which two have 5 V across them. Then attach wires to both and the other end of each wire to the positive and negative leads on the battery itself. I would use a different cable (not micro-usb) so that the leads are larger and easier to access. If you cannot do this, then you could use a stand-alone battery charger like this:
http://www.verizonwireless.com/b2c/...peId=12852&accessoryId=48042&initialPhoneId=0
But that would require you to buy one, which may be a waste if the phone is actually the problem. But if you do buy it and it turns out the phone is the problem, you could keep the receipt and get a refund.
As far as clean the leads on the phone, you could try mixing baking soda and water (little water) into a thick paste and scrubbing with a tooth brush. The paste will need to sit on the metal leads for some time (30 mins to 2 hours depending). Then use isopropyl alcohol (rubbing alcohol) on tissue to clean any remaining garbage/residue. Then you will need to let it dry again, ideally in a sealed container with silica or rice. I would probably leave it in there for at least 24 hours.
If both of these don't fix the problem, then you probably have either shorted some internal circuitry or have some other corrosion inside the phone somewhere.
Well I really can't try that suggestion broke college student and all. Thanks though.
You can get this external charger cheap. I have it, works fine:

Here's a battery to go with it:

Hello all!
I recently purchased a used Droid Razr Maxx from a co-worker. The lcd screen was cracked so I replaced it. I took apart the phone completely and reassembled it with the new screen in place. The phone turns on just fine, the Motorola icon shows up and it gets to the charging battery icon with 5%, but after a few hours of letting it charge, it stays at 5% and wont turn on. Keep in mind, the phone has been charging for two hours from the time this post was made.
My question is, did I somehow damage the battery when operating internally? I can replace the battery if needed.
Another question. If I damaged the motherboard, would the phone turn on at all?
I am kind of wondering if there is a certain thing I needed to do before plugging it in.
To answer any questions that might be asked: The battery was completely dead when I did repair the screen. The charger is a wall usb charger, not plugged into my computer. I did place all the components inside the phone, to the best of my knowledge. I have had experiences when it comes to internal repair.
check for how long this 5% charge remain. it usually happen due to problematic battery guage

Morning now. The battery is still at 5%. The phone shuts off soon as the charger is not connected. Does not seem to hold a charge. Think I should buy a new one?

It could be a faulty charger.
Normally, If the battery is poor, it won't hold charge but it won't stick to a particular percentage. It will only discharge sooner. But given the fact you got the phone dead, it might as well be the battery.
Worst scenario, you damaged the charging port.
I'd begin with using a different charger, if that doesn't work, try another battery.

I have used other chargers and they all work for my other phones, just not this one. I am hoping it's a dead battery and not something to do with the motherboard. My friend wont let me dismantle his phone to see if it's the batter, lol.
Just the clarify, the phone doesn't boot up completely, only to the charging screen. The battery icon with 5% shown. When I unplug the phone from the charging screen, it just dies. Will not even boot up to the phone animation.
I purchased a battery replacement off of Ebay. It'll arrive in a few days. Let's hope this works!
Still could be the charger. Did you check voltage and amp specs? 850amps 5.1v
This phone can be picky. First razr I got had broken screen, repaired it and found myself in the same situation.
Connecting to a laptop would not charge it. Only stock charger. IPhone charger or chargers designed for iphones will not work.
Edit: When replacing battery, position is critical. If battery terminals are a little bit displaced it will not turn on.
Displacement can be minimal or imperceptible but will cause troubles. If possible don't place cover before checking that it turns on. (please avoid touching circuits or battery terminals or will get worse).

That was exactly the problem....
I got the new battery, but not 24 hours later, I was realigning the cables inside it (like the front facing and rear cameras, along with the WiFi antenna) I slightly moved the replaced battery and the cable to the battery to the motherboard tore itself. After a long face-palm moment, I got the old battery back in place and realigned it very carefully. It turns out it still works, but I am out a new battery.
Apart from the battery, I need to find out why the front speaker won't work. Either the speaker is damaged or something needs to be in place correctly, besides the cable. Also need to get some adhesive gel to bond the screen and case together.
Damn I really had forgotten about that speaker. The fact is it tends to break. It has very fine copper wire winding that can break when you remove it the wrong way.
Having no experience I pulled not knowing that speaker is glued to motherboard. At that time I didn't knew it and thought that little bar left was part of the motherboard.
Since you disassembled almost everything, that must be the reason it is failing. If it is not that, it is badly plugged but I really doubt it.
Alas Never fixed it, so i can't tell correct process to reassemble or disassemble that speaker. Instead I searched for apps that would activate loud speaker automatically during calls.
Would have been nice to fix it but I got the opportunity to acquire a RAZR maxx so never touched and sold instead.
Removing that glue might involve using a hot air gun. So that you don't damage motherboard removing by force. (But again too much heat could Fry motherboard)
Maybe someone could share it's experience?
About that screen, Remember to have read about a 3m adhesive spray in some thread.
Also some one just passed hot air that melted original glue but it would be better not to play with heat over a battery.

Hello,
firstly i m sorry if this is the wrong section, i m new here.
Now to the issue. I have a Huawei P30 Lite with broken LCD. I replaced the LCD with an original Huawei service pack which included LCD, Frame, Earpiece, Battery, buttons etc. Basically it included everything except motherboard, charging board and coaxial cable. The problem is that after the replacement the phone is not charging. At first it was showing that it was charging without any success (% going down instead of up). After the phone battery drained, there is no charging at all.
Doing a full hardware check i noticed that there was indication of water damage on the charging port. I replaced the whole charging board. Still same result.
Reinstalled the old LCD pack (battery had some juice in it still for testing) with the same results. When the phone is turned on, i get a charging signal and the LED indicator but without actual charging. When phone is turned off i dont even get the LED indication of charging.
Steps i already took to save time:
Changed the charger. Used up to 2.1A charger with fast charge cable aswell.
Changed the charging board.
Tried both new and old battery, internal connectors etc
Cleaned the whole motherboard with alcohol to get rid of any debris even though there is nothing visible
The phone was working normally before the lcd replacement.
The phone is working perfectly with the remaining battery and was working perfectly until the new battery drained aswell. Only problem is the charging.
Cannot perform cache cleaning since battery is dead
Software upgrades, reinstalling etc will certainly not be of any help since the phone is not charging when turned off.
I am trying to avoid costly and time consuming repairs since the only fault i can assume anymore is human error which most likely i would have noticed during the repair. I cant accept that the main board died suddenly after a simple 2 part replacement and the only thing affected was the one that had water indication on it which didnt affect it so far.
I am looking for any kind of ideas since i am totally out of them.
thank you for listening.
Hey, i know its 1 year later but i wanted to ask you about this. I had the exact same problem as you with a p30 lite aswell. Did you find out where was the problem? Could you fix it? Thanks
