Hello, I've had a Samsung Epic 4g Touch just laying in one of my drawers for about 6 months. This phone it was my friend's and he gave it to me since he couldn't do anything with it. Now that I'm trying to turn it on it does not respond to anything. I doubt is the battery because this lithium batteries last a lot and this phone was barely used. I've had this issue when I used to had a nexus s and it was solved by taking the battery out and holding the volume down and power button while I connected the usb cable and inserted the battery back in but that method does not work on the epic 4g so called galaxy s2. Does anybody know what could I try since the comluter does not recognise it when plugged in?
Does it show to be charging when plugged in to a wall charger? If it laid in a drawer for 6 months I'm quite sure the battery is totally dead and will need to have at least a little bit of charge on it before the phone will turn on. When these batteries are dead for an extended period of time there is a good chance that it will never be as good as new.

You may need a new battery. If it was stored with 0 charge for 6 months its most likely got dead cells. You should always store li-ion batteries with 40-80% charge, in a cool dry place and removed from the device.

It does not show anythign when plugged in a usb or wall charger. Im gonna go to a sprint store or cell phone store to see if the phone works with another smae kind of battery.
Found the issue is the usb not charging. Took it to a sprint store and as soon as they put in another battery it turned on but it did not charge. Now I'll need to figure out how hard is to fix the usb hub if either just some soldering or if it is the whole usb hub that need to be replaced.
Hey guys I founf the issue. When I took the phone apart I noticed the last of the prong on the left that is connected to the usb hub is damaged like burnt or maybe broken I can barely see it. Is there a way to replace it or fix it?

Hi,
Does anyone know how I can charge the battery without the phone?
I tried to connect a USB cable (red & black wires) tot the + and - of the battery (correct polarity, I checked on the internet).
But that doesn't make sense, battery isn't charged after several hours.
Does any1 know how I can do this?
Thx very much!
Pieter
Why not just get a charger from eBay or Amazon? Doing it your way, even if it sort of works, may do serious damage to the battery. And the last thing you want to do its smoke a lithium ion battery.

not sure if it safe/possible to it any other way then in the phone or a charger ment for it. there are universal ones and ones specific to the g2/dz that charge the batter without the phone. if you were do get it charging another way you may overcharge it, granted I believe the oem batteries should have a function to stop the charge @ a certain point but why taje the chance?

If you can afford to check on amazom.com. I bought an universal external wall charger from them and it came with 2 batteries as well.

Thx 4 your help.
I will explain why I'm asking this question:
the USB port of my Desire Z is broken.
I have ordered a completely new motherboard to fix this issue.
The board will be send to my homecountry from Hong Kong.
They will send it this week.
Until then, I have no Desire Z because the battery is empty and I can't charge anymore...
I can't remember the brand, but over at Staples there are these 7$ USB adapters for just bout any kind of battery , you just move the prongs to the contacts on the battery and slip it into a USB port (but given how our batteries have the contacts on the bottom instead of on the wide surface that may be difficult).
But yea I would say using an actual charger would be your best bet.
Where did you order your motherboard from?

here you go, something like this.
Hi Guys,
Got a problem here. This will be my 2nd Note2 after sending it back to Samsung couple of months ago. It was charging this morning and tonight after a long day of work, I decided to play some game on it. Noticed that the battery is on 15% I decided to charge it. After 30mins I checked the status of the battery and to my amaze it was not charging! I tried 3 different cables, 2 different chargers, and none of them works. Tried my cables and chargers to a different phones and it does work. I connected my note 2 to my laptop, and it does not recognized it. Tried to charge it while it is turned off, I can see a battery icon, but it does not show the charging battery icon. It will disappear in a few seconds. Please see image below:

It's a rooted phone. Tried to clean the charging port. I even opened it without damaging the warranty sticker, and I can definitely say that there's no moist inside. But just to be sure, I blow it using a hair dryer with the temp off. But with no luck. I used to experienced this a few weeks ago where went back charging after a few minutes. But this time it's worst, it's been an hour and a half and still it is not charging. I can't do a full wipe yet since the battery got 9% left on it.
I know that if it will really not charge, to resolve it..it's either I send it back again to Samsung, replace the board myself (hope it works), or buy an external battery charger. Unless there's more that I can do to fix it.

I did but to my amazed after leaving it alone the whole night, It went back charging again. Yes I am glad that it's working again but I am worried it might happen again sooner or later. I have read some threads with the same issue and with the same outcome, I really want to know what's behind this.
So if its under warranty unroot and monitor

Phone can not be charging when off
Hello all,
The problem is i can not charged my phone when the phone is switched off. When i inserted the power cable it will automatically switch on the phone then it will charging normally. I am on Phoenix ROM V18.8. Your kind feedback is much appreciated. Thanks.
So Yesterday I put my phone on the charger and noticed after 2 hours it stayed at 5%. And though just to restart the device, however that didn't work. So at 3 am in the morning I turned it off and threw it on the charger over night woke up to find its at 1% as I type this now.
Is it my battery that's done for or my Note 3 HW?

try new cable and charger base. If neither work, call for replacement.
Or get a new battery save yourself the time you'll have to wait to get another.
It's probably the usb cable, mine went out a month ago, same thing happened to me it wouldn't charge tried another cable battery charged without any issues. So more than likely the cable is bad.

Well I ordered two new anker batteries along with the external charger, and that but that's my problem nothing wrong with a charger or USB cable. My battery just simply would not charge it could not hold one anymore, I literally put it on the charger the entire night and the phone stayed at 5 percent and then as soon as I started do anything on my phone it literally shut my phone off while on the charger during a text message.
I guess it just died.

This same thing pretty much happened to me. Actually exactly the same thing... including the extra Anker batteries and charger as well as testing different cords. I ended up ordering a wireless charging kit, and now all is well. I've been using it with one of the Anker batteries. I ordered the Koolpad charger and the white slim wireless chip off of Amazon. It charges through my Seidio case, and I put velcro onto the charger and the back of the case so that I could easily use it while charging. The wireless charging kit cost about $40 on Amazon (I imagine pretty close to what a new official Sammy charger and cable would cost) and the Koolpad charger came with a black and a white micro USB (not USB 3 but still...) port cover, which I thought was a nice touch.
No guarantee that this would work for you, of course, but it did for me fortunately. If it didn't I would have taken it back to the store (after re-flashing the stock ROM, which may have solved the problem on it's own). Oh yeah, not really sure if this is actually related / possible but I did theorize that the problem may have been kernel related. I had actually been following the wireless charging thread anyways, but if I wasn't already considering spending money on that, the first thing I would have tried would have been a clean install of everything. I was testing out different kernels with Tweaked ROM and the problem started around a new kernel flash, but really can't say if that's related because I was unimpressed with that kernel overall and flashed one that ran better on my phone around the time that the wireless charger showed up (got one day shipping w/ Amazon Prime because shutting down my phone to rotate batteries got old quick, as I'm sure you'll agree). Anyways, good luck. There's lots of good info in that wireless charging thread, if you decide to go that route.
Hello,
I have several Tab Pro's that are all having the same problem. I have charged the devices to 100% then when it sits for a few days it will not turn back on. I have plugged it back in and it show 0%.
This is what i have done to try and find the issue...
1. I have reset all cables
2.Tried different batteries (USED)
3.Re-Rom with ODIN and Factory reset
4.Checked the pins on battery terminal for bad solder contacts
5.Waiting on new batteries
Now the interesting part. I charged 2 devices to 100% then disconnected the battery from the Logic board so I could check to see if the battery is discharging on its own. After 3 days I reconnected the battery terminal and tried to turn it back on. They will not power on, then I plug in the charger and battery icon shows up with 100% and then I'm able to turn it back on. Any ideas what the issues with these are I have about 8 of them all doing the same thing?
Thank you,
The battery doesn't discharge on its own so fast like your description. I have a Tab Pro 12.2 , which is off almost 3 months, when turns on it still keep the charge at 99%

The problem is from the cracked battery connector, it will cause intermittent connection. Trust me, remove the back cover, use your hand to press directly on the battery connector while turning it on, it might work depending how bad the crack is. All you need is resolder the battery connector.

I have tried to resolder a few of them and they still do not turn on or they discharge the battery. I have a few that I charged the batteries up to 100% and disconnected them from the battery terminal on the logic board over the weekend. They all still do not turn on, then I connect the charger and the battery icon shows up with 100% then I can turn it on. I have tried what you said and pushed on the terminals on all of the ones I have and not one will turn on. I'm starting to think there is a issue with the power management chip on the board. Has anyone tried to replace any of these?
I have had issues with SM-t/p900 12.2 pros that had the issues you are talking about, not charging, flickering screen, and the terminals needed to be resoldered. I could actually push the pins up and down. The SM-t520 pins are solid and do not move.
Hello everyone. My question is related to the pin connector and battery life:
3 months ago, i though it was moment for battery replacement of my S 8.4, but in the process i broke the 6-pin connector placed in the board. So, I tried to deal with it and charge the new battery once, with the connector slightly detached and badly soldered. It went bad since wasn't charging normally, i screwed badly the connector so had to replace it.
I ordered the new connector with an official tech support. Connector took few weeks to arrive (i live in Chile). I did the microsoldering with a lot of troubles, and after watching tutorials and buying soldering stuff, practicing and studying the possible troubles i could face, i finally did it (see the pic). Anyway I'm skeptic about what i just did XD (btw i used soldering paste for smd, really cool stuff)

Now it's charging, after 3 hrs it went from 20 - 90%. My questions are 2:
1) considering that many experts point out that lithium battery's first charge is extremely important for technical reasons (SEI forming on first charge cycle; non full charge leads to fading over time), should i replace my battery soon, if i stored at 20% for 2 months?
2) how do i know if i soldered correctly the connector, should i consider the time it takes (normally charging cycle was around 3 hrs 30 from 0 - 100%)?
Thanks!
need help with soldering
Hi buddy , have a similar needs as yours, except in my case i did not break the connector , it broke by itself after a few months , guess a bad solder at the samsung factory itself .
So now coming to the point , i ordered a new connector and was thinking to solder it myself as service center was charging a hefty price for a small repair . Could you please guide me as to what all is required to do it properly .
li-ion battery`s dont need a forming charge on first charge.
Dont run the battery too low as the battery can fail, I don't go below 20% (I use a charge level alarm)
I don't charge above 80%(I use a charge alarm) , I have charged to 100% only 7 time in 28months(only after flashing or upgrades to calibrate the battery gauge)
i have used my T800 every day and no problems so far.

Im also having the same problem...
The connector pin just came off from the motherboard...In my case..im so afraid to do the microsoldering,however i tried “reflow solder” heat up the connecter while sticking it on the motherboard for few seconds...then let it cool...yes it was succesfully connected..but its not strong enough...it just came off again when i grabbed the tablet to put on its backcover...The main reason why im scared to do the microsoldering is what if i accidently damaged other components in the motherboard...is there any other way to solve this issue other replacing the motherboard...
