battery changed, phone switches off randomly
i've changed my battery, and now it sometimes switches on and stays on, and sometimes randomly powers down, or, sometimes when i switch it on it keeps cycling to the apple screen over and over. the new battery was 57% and then charged up to 100% really fast.
i'm also almost 100% sure about the screws, i stuck them to tape in the right configuration and didn't tighten them too much.
Is this a good question?
