Specific strange battery loading behaviour with EU-Charger

FYI:
Ysterday I dedected a strange behaviour of battery charging:
While on Tuesday, when I received my SGS II it was charging quickly with the original EU-Charger while setting up my SGS II and then driving it to it´s (still unfound ) limits it loaded pretty fast up to 100 %.
Day 2 and 3 no prob at all.
Yesterday while filling up my 32gb SD card with music and videos over KIES air (SGS II charging with original charger) battery started to degrade while in action.
Ther I switched it off, let it load switched off for 2-3 hozrs and when starting up it showed only 94%.
Did not worry about this.
But last night I left it switched on and charging, showing that it is charging, but this morning found it stuck at 84% batt cap.
Switched it off, charged it for 1 hour, switched on and still on 84%.
Now I plugged in my travel charge adapter (hama USB Charger 5V 800mA), SGS II switched on in idle and within 2 hours it was full at 100%,
I suspect the original charger to be faulty .....................

[Q] Critical battery icon showing when powered on.

I left my phone charging overnight via the wall charger. Battery registered at 1% when I started the charge.
When I woke up this morning I had a large low battery icon on the screen and the phone won't turn on. I disconnected the charge, tried charging with another charger but everytime it shows the SAMSUNG logo, then the large low battery icon.
I tried removing the battery, cleaning the charger port terminals, swapped out different USB cords, everything but a hard reset.
No matter what I do the phone will not start up.
Has anyone experienced this before, or possibly no how to resolve it?

Happened to me several times (on both my focuses Rogers and AT&T), and I came to the conclusion it's a bug somewhere in the phone or the battery. I'm not sure exactly where the problem is (software, hardware) but I can tell you how I fixed it.
What happens is, the battery is almost depleted, it actually is 1%. The phone incorrectly reads that thinks it's charged fully and doesn't allow further charging the battery. So, you're not able to charge the battery correctly.
Now, as I previously stated in some other posts, I recommend having a standalone charger (Samsung i9000 ones are compatible are very cheap) as well as a secondary battery. The depleted battery gets charged fine in the standalone charger and when it passes 5% charge, it can be charged fine (again) in the phone.
This doesn't happen often, I believe it happened 5 times in more than 300 charging cycles (2 phones x 150 charges, I have them for over a year) so it's not that common.
I also found that it *may* work if you charge the battery in another phone.
As a general thumb rule, it's important not to leave the battery to completely discharge, and connect the charger/usb when it reaches about 40% (when you can, ofc). Please refer to my post here to see how you can preserve battery life.

Photon Q got hot now won't power on

Hi everyone,
My Photon Q was probably about 30% charge when I last checked with it on. An hour or 2 later it was a little warm and was off. So I went to charge it using the car charger with 500mah charge rate. I came back about an hour later and the phone was really hot and no charging screen so I unplugged it. The green led light is lit when the phone is plugged in.
I tried holding the power button and volume down button, but it won't boot. If I have the usb charging cable plugged in from a PC or charger adapter when pressing those buttons, the green light will flicker off for a fraction of a second.
I then proceeded to dismantling the phone as I suspect a battery issue and the one in this phone is stupidly non-removable. After taking the back cover off, I tested the battery posts and received 0 volts. I still don't know if the battery caused the drain or if there's a short in the phone. I then took off the inside cover that holds the battery in. A few T5 screws later and the battery was removed. I connected the battery to some AA batteries in series to see if I could get a charge. A few hours later I got it up to 3 volts which held for several hours. So I connected it to a few more AA batteries in series to try and raise the voltage. I got it up to 3.67 volts and the battery is listed at 3.7 volts.
A day later and the voltage is still at 3.67 volts so I put the battery in the phone. I went to try and power it on, but nothing. I then connected it to a usb cord and received the slow flashing red led light a couple times before switching to green. The battery started getting warm again connected to the usb charger. After 20 minutes it was approaching hot so I unplugged the USB. The battery read 3.54 volts. 30 minutes later, 0 volts again.
Does anyone know what the actual voltage range is for this phone, as my old Samsung M320 is also 3.7 volts, but when testing the battery I get 4.10 volts? I heard it's pretty specific on minimum voltage. Any ideas for a temporary battery or way to boot the phone before spending $50 on a replacement battery and then find out there's a short in the phone. Is there another key combination to boot the phone, I'm trying to boot it to at least get my pictures and other data off it.
Thanks a lot in advance
Matt

Not the battery, seems to be an electrical short but where
I bought a new battery for the phone which had a 0 volt charge when I received it. I tried putting it in the phone as is to use the phone charger to charge it, but got nothing. So I charged it using 2, then 3 and then 4 AA batteries in series to get it up to 3.7 volts. I then put the battery in the phone and noticed the 2 large chips and the chip centered above them located by the camera get a little hot. I tried with the charger connected and not connected, but same thing. Power button doesn't turn the phone on. Just the green led lit when the USB power cable is attached. So now it seems there must be a short in the phone. Anyone know where I can look to check for a short, blown resistor or something in this phone? Or at least where the rom chip is located so maybe I can turn it into a usb drive to get my data at the least.
And sorry about the double post. I didn't receive any replies in the other section and I really need to get some data off the phone. Seemed the hardware section would be the place to check. Tree fell on the house and pictures before the tree was removed were taken with the phone which of course ironically stopped working right after.

[Q] new battery dont charge

hi i have a nexus 4 12 months . i bought a battery from ebay 5 months ago .before 1 month my main battery was inflate a little and the back housing of the phone cant close proper.i swaped the battery .the new battery charge only to 16% and then discharge with the charger on .when i plug out the charger the battery discharge fast to 4% and shut down.
i bought a 3rd battery from ebay
i charge my phone closed 30min now and the phone dont have power to turn on.
the charger is the official with the official cable from lg
I do something wrong??
sorry for poor english.

It could be the charging flex that is broken. But these batteries from ebay could easily be bad copies which don't work. I know spareslg.com sell genuine parts if you want to be sure.

I have a similar problem. The battery was draining really fast and not charging when plugged in, so I got a new battery. It still didn't charge so I tried a wireless charger. That does work but it will not charge via USB. When plugged in, the icon changes to the charging icon but it doesn't say that it is actually charging. In the battery status screen it says "not charging."
Would my next step to be to try to replace the USB port? I've cleaned it out as best as I can with a toothpick and used some contact cleaner as well.

I think the problem is with the way you replace your old battery
Are you sure you replace it correctly ?

I had previously successfully replaced the screen after I dropped and shattered the phone. To do that, I successfully disassembled and reassembled the phone with no issues. I ensured all connections were tight when I replaced the battery and disassembled again tonight to check all the connections and the battery still will not charge -- both the old and new battery. I do not believe at this point that the battery is the problem.

S3 neo charges extremely slowly if it does at all

So I let the phone get below 15% the other day and I plugged it into a charger from an older samsung device and continued browsing. Before I knew it the phone was at 0% and it just shut down. While still plugged in, the phone made a few attempts to boot up but at the end I had to get the battery out. After getting the battery in and plugging in the charger again the phone didn't show any signs of life. Like I hard bricked it. After a few desperate attempts the screen flashed and a few minutes later the phone booted up like it normally would (This happened while it was still plugged in). Now it just won't charge as quickly even with the fast charger. The phone normally gets pretty hot while charging, now it just stays cold.
NOTE: I had it charging trough the night with the old charger but it didn't go over 15%.
I am running Ressurection remix 20150714.
I think it's got something to do with the hardware, and if it does, would the warranty fix this?

That's really not normal if your phone don't get hot while charging
Try a different cable (maybe it charging too slow), buy a new charger or charge your phone on PC. Check if an app use much battery/CPU and check if the battery is swollen or try an another battery. Update your ROM version maybe it's a software bug or reflash it. If nothing solve the problem then maybe you need to clear the usb socket of your phone or it's maybe damanged . Be careful if you clear the usb socket!
Sorry for too much maybe's
Good luck :highfive:

I checked the port, it's pretty nasty but I doubt that's the problem. I'll try and clean it up with a toothpick or something.
Checked the CPU usage and apps and it all seems normal.
I'm not home currently, but I'll do a full reset and roll back to cm11 when I get back.
I've used a travel charger from an older device, an Alcatel charger which actually charged my phone and my factory charger. The factory charger works best for now but it still takes like 5 hours to charge. The phone took less than 2 hours before...
Anyway thanks for the help so far, I really appreciate it.

How much mA you get while charging with the original one? Check it via Gsam battery app

Downloaded it, here's what I got.

Gsam is alternative of Bbs, but with better gui. Look at my ss - I can saw mA of discharge and charge the battery. With stock battery Ive got around 750mA

Yesterday for whole night i kept the mobile for charging and it showed 8% charged i thought it charged up and removed the socket before I knew it the phone was at 0% and it just shut down. While still plugged in, the phone made a few attempts to boot up but at the end I had to get the battery out. After getting the battery in and plugging in the charger again the phone didn't show any signs of life. Like I hard bricked it. After a few desperate attempts the screen flashed and a few minutes later the phone showed the sign of charging but it ended up (This happened while it was still plugged in). Now it just won't charge as quickly even with the fast charger and it wont shows any sign of life.
NOTE: I charged for whole night but is charged to only 8%
