ds not holding charge/charging at a certain angle
My 2ds ended up having issues (seeing as I got it when I was like 5) so I bothered my brother for his, thinking it would be better and overall it's great, and everything works, except the battery, it will only charge at a certain angle, and for some reason it won't stay charged, I asked him about it and he told that he also hadn't touched his for a really long time, so he doesn't know.
I've looked into it, and similar issues say battery issue, but non say anything about it only charging at a certain angle, and I was just wondering if it's possible to replace the charging port too? And of so how much would that cost..?
I'm 15 but bro I make genuine pennies, I got a job, but I just don't get paid too much, that's why I won't buy a new ds unless necessary so is this maybe a possible cheap fix..?
