Battery on the way out

Daphone

Sadly it seem like the battery in my Z are on the way out, it have swollen a little and are pressing on the back of the screen so it have a 0.5 mm gab in one side.
Sadly the timing are very bad so can only afford a really cheap phone to replace it until i can buy a 5G phone, i was hoping the Z could last untill 5G was a thing here, but i doubt it will it started about a week ago when my 4-5 days battery time suddenly changed to just 2 days.

Now i just hope it don't burst into flames while i try to find some money for a new phone.
