The new battery is great ^^ 2200mAh!!!
Now I can play with my Megadrive emulator during more than one hour (I tried and it can be used during 2 full day before the smartphone say me that the Battery getting low )
I think that I'll try to repair the old battery, but the new works great at this moment, so I don't really need the old one
