[tl;dr]If i remove the battery from my phone is it possible to charge it? My phone has been unresponsive since i tried to charge it with a new usb cable. I checked and it seems the problem is the charging port , i consulted some repair guys and they told me that it’s hard to repair it and would not take the risk. I don’t really care for the phone my priority is to recover my data So I was thinking of removing the battery and recharge it then put it back again and do backups but i was wondering if this is even possible or if i need any special tools or if there is another alternative

I wouldn’t recommend it. (I’m a repair guy too) If it’s the bare battery then you won’t have the charging control board. So you could risk fire or explosion. It might be possible to connect a DC power supply to the phone (instead of the battery) long enough to get the data but I don’t know enough about that phone to be more precise.
