Update 23 November #1: final voltage setting.

Yesterday the battery charged again. I used up it's charge to 18%. After a night it was 17%. Today I tried to use it. I could without power supply till it dropped to about

11%. I guess the battery voltage is dropping. I connected my power supply again. Set it to 4.3 volt. Android shows that my charge is dropping. It drops to 8% and remains there.

Even running 3D game the charge stays at 8%. I measure the battery voltage and it's 0.03V. Battery Temperature normal. Not even warm.

After removing the battery and re-insert. I had to set the power supply voltage to 5.5 volt to make the phone boot at all. The phone draws a current 1.1A (there was a moment it drew 1.8A, did once) ,when I use it heavy. Like running a 3Dmark demo Icestorm. The best settings to make the phone always run: 5.5 volt on the power supply.

If all remains the same and all ok. I will then stop posting messages on this thread.

Update 23 nov 2014 #2

The battery charged to 100%. The battery voltage went to 4.4 volt. 4.2 volt supposed to be the Vmax. Above 4.2 volt is not recommended.

From this moment I cannot recommend anyone trying this home. Will see in the future if the phone can run or a dead battery. Going to drain for a longer period.

Update 22 november 2014 #1: With success I am using a my Samsung Note 3 directly connected to a lab power supply.

Needed materials Final list:

- any smart phone with a Li-ion battery which is chemically dead! Very important! This li-ion battery must show 0 volt.

- A lab power supply like this one Basetech BT-153 (https://www.conrad.nl/nl/basetech-b...c-0-3-a-45-w-aantal-uitgangen-1-x-393647.html)

- 2 small pieces of copper sheet

- any strong tape that cannot conduct electricity

- some technical skills. Ask a electrical engineer if you are not sure what you are doing!

Update 22 nov 2014 #2:

After running the 'broken' battery at 5.3 volt. The battery is chemically active again. I measure 3.9 volt. It charged back to 64%.

I am wondering if the Samsung battery and phone is able to / not able to run if the battery is broken. Perhaps the phone ran because the high voltage made the battery chemically active again. I am not sure. Going for another deep discharge again and let the battery lay on the shelf for a week. And keep it draining energy with a resistor and LED.

Have fun! Well I am =)

Work in Progress (WIP) Highly experimental. Hope to finish my research and provide a safe way for any user to make a dummy battery. And that the phone is powered by

a external powersupply only.

Remember that Li ion batteries can become extremely hot and can explode. Don't short circuit, damage the metal casing any way!

In my previous attempt, I was almost there, but at the last moment I had to give away my loyal S6312. Perhaps later I can finish it.

Previous post for S6312: http://xdaforums.com/general/general/guide-power-samsung-phone-battery-t2923590#post56778430

- Don't dissesamble the battery. The reason is that there is an electrical protection circuit inside the li ion cell. Without the cell and protection circuit the outer electronics, that is in

the battery connector housing, it will not work and your Samsung phone will not recognise it as a working battery, and will refuse to boot.

This guide is tested on a Samsung Note 3 N9005, but if my guess is right, then you can use it for pretty much all the Samsung phones! Let's wait and see.

In this attempt, I am confident it will work. My overal plan is:

1) Get a defect battery. Completely drain it to make it chemically inactive.

2) Hook the battery , that cannot charge, onto a lab powersupply

3) Run your phone at your desk without the recharging the battery.
