I pass on to detail my problem. 
I have two years ago the phone and the battery was lasting me two hours. Before replacing and even with the new I bought the following happens: 
When I low battery (20%) is the symbol shown on the picture (kind of traffic sign "No Parking" but without the E) and then I get the screen starts flashing a few seconds until it finally goes off. I try to turn it and no way to turn if you do not plug in to the mains. When you turn on the battery is at 0% and if I unplug switches off. I thought it was the battery problem but changed (for one that is not original) and is still happening. 
Have any idea that I could be?? Someone will it happen? 
I am root and I got the latest version of Android 4.1 Jelly Bean. 
Hopefully you can help me.

Good, I tell them. 
I had a similar problem, I went out the warning icon next to the battery and not turn unless degas connected via USB or wall. 
The way around this is to buy a new flex (where charge and plug the usb) sells full plate. 
I got on ebay and bought a kit to disarm the cellular and change the board. 
now, works great ...... from what I read, going on all S2 after a period of use. 
if you want, I pass the link of felx I bought  because if one trucho compraun, you might get in trouble!

Hello, I would change the plate load pin and let me grab the signal is in E or sign prohibited. It might be a problem of the new plate as the previous had no problem with the signal.
