After it bulged i took it to a mobile shop they changed the battery but after 1 month it bulged again they had a warranty now they r saying its not the battery problem but an IC problem And they will charge me heavily so now i have the iphone with the heavily bulged battery in it all the touch and performance works normally only that its battery bulged and broke a bit of the screen Is there anything i can do ? i dont know what to do with it now.
It is a problem that happen often with iPhones, the charging IC chip get burned by using non certified chargers or cables, due to non certified batteries or just gets bad because is a old model. About the bulged problem can be a power issue (like a charging IC), or heavy changes in temperature. If you trust them change the IC with them and keep your phone alive, if not find another locations and get estimates. Last thing, micro soldering jobs are expensive because you need the right people, the right training and the right tools to complete the job.
