Phone won't charge? - Sprint Samsung Galaxy S III

I've had my phone for about 2 or so months and it hasn't been charging. More accurately, it's been charging extremely slowly. Ever since the first time I've charged it, it has yet to ever charge to full battery even when I leave Kris charged overnight. I've already changed the battery and that hasn't affected anything so I'm pretty sure it's not the battery's problem but the phone's problem.
I don't have any mega-draining apps downloaded or running (I always exit fully out of my apps) other than the default ones running in the background. I've also tried switching chargers to no avail. I've gone from the Samsung charger that came with it to another USB cord to a battery-only charger and none of them have worked. I charged it overnight but today when I disconnected the phone from the charger my phone just shut off.
If you could help me at all that would be very much appreciated

Could be a faulty charge port?

I had a similar issue and traced it to the charging cable. I swapped the cable (not the charger) between my phone and the wife's and the problem followed the cable. Got a new one and the problem was solved.

Best way to test is with the power off

[Q] Bad battery

Hi,
I've been using HTC Desire for 6 months and I got this problem lately.
First, please have a look at the battery icon. What does it mean?

Second, during the day use, my phone just freeze for no reason. And when it's freeze, the screen is totally off and the notification light flash 1 green, 2 orange continuously. Then I have to take out the battery, plug it in and turn it on to use. It just happens so randomly.
Third, it happened just now. I played game till the battery gone and left it on the table and went to sleep. But when I woke up, plugin the USB charger (I forgot the main charge at work) and it didnt charge. I turned the phone on and saw the battery icon was like what appears on the screenshot above. I turn it off and on again, the battery became full magically
So what caused all those is the battery? And sometimes when I use the phone for a long time when the battery get hot, it's freeze like I described as well.
Anyone got in the same case as mine?
No one knows?

Unusual battery behaviour

Hi,
I bought this tablet (Tab S 10.5 LTE, model number T-805) on September 2014. In the last month I'm experiencing weird battery behaviour, like the one in the screen attached. I had about 50% of battery charge and I started a game like Angry Birds 2.
In a matter of minutes, the tablet warned me that the battery charge was under 15% and after another minute the under 5% charge warning message appeared.
Questions:
1) is the tablet battery already worn out? Do you know if Samsung European warranty cover battery problems?
2) Before sending the tablet back to Samsung, should I try recalibrating the battery? I have an old power adaptor with 5V 0,7A (or 5V 1A), should I try a a "slow charge" to see if the battery situation improve?
I have the latest firmware, lollipop 5.0.2 and I did a factory reset after the update.

Do a battery re-calibrate is the first thing i would do.

Thanks Thinderbox, I'll try with root and battery calibration.
Update: after a battery calibration discharge rate of the battery seems back to normal. Thanks again @Tinderbox (UK)!

[Q] - GNex doesn't charge battery, high discharge, very hot PCB, overheated battery

Galaxy Nexus GSM I-9250. Tested with 2 batteries (one original with NFC antenna, other aftermarket clone without NFC).
Actually GNex doesn't charge at all: no charge animation when phone off, both batteries at 0%. Unable to power on.
I've ordered a replacement for Micro USB + mic + charge flex cable.
Before that, discharge was very fast and charge very slow: I have seen charge animation when phone off, I was able to boot Android (custom ROM and kernel with LP 5.1.1), phone showed always 0% of charge (sometimes I was able to read 10-15% but discharge rate 1%/minute when plugged to AC/USB), battery temp between 51° C and 60° C, health always overheat.
Disassembling it, bottom side of board, was hot, during change, near TWL6030 (orange boxed, see image)

And top side of board was hot near Samsung KMVYL000LM (orange boxed, see image)
Inspecting kernel messages, I haven't found any significant error. Only some OMAP thermal throttles.
Hints? Suggestions?

USB C dock/craddle

Hi guys,
I'm getting my Pixel 2 in few days and I'm currently looking at accessories on Amazon. I would like to get a dock/craddle to recharge overnight on my night stand. I don't believe I need fast charging/PD for that, since the Pixel will have all night to charge. Do you have any recommendations ? I can use my Google charger power brick if the dock doesn't come with one.
How much time does the Pixel 2 takes to charge anyway on fast and slow charge ?
Thanks,
Neo.
I looked into cradles and to be honest they are way too limiting. In order to use them, you have to put the phone into a slot so that it charges, it is fixed and not very flexible.
Instead, I use a mount called a Clutchit and a regular power cable.

With it, I can just place it on the mount, in any orientation (portrait, landscape or anywhere inbetween). It just holds it and it is very easy to take and put it back on without worrying if I got it into the slot correctly. It will even hold a tablet.
I use it with a 6ft cable to an original Pixel 2 charger plug and chargers in Rapid mode.
No association with them other than I own several of these.

Galaxy Nexus (toro) dead?

Yesterday, I tried to charge my Galaxy Nexus (toro), which was fully depleted. It showed the battery icon like it usually does, but then it went kinda weird (idk how to describe it, look at the picture). Then it would turn off and do the same thing again. So then I charged the battery using an external charger, but the phone did not do anything, like it didn't even vibrate. If I connect a charger to the phone, I can get into the Bootloader, and if I go to recovery mode, it starts for like a second, but then turns off again. If it helps, it's the SCH-i515, running Unlegacy 4.4.4, and TWRP 3.x (not sure of exact version).

EDIT: I plugged it into a laptop, and it booted up just fine, but the battery was at 0% even after being left in an external charger overnight.
Maybe the battery is dead dead... Like when a car battery has a dead cell. It works when you plug it in because there's a charge going through. Do you have any extra batteries lying around that you could test. Just remember that you are fighting a losing battle against time which degrades battery life.
