iOpener kit recommended, otherwise went as charm

My Problem

Battery got worn out.

My Fix

Replaced the battery with the one I ordered from iFixit. Couldn't pull the glue strips from under the battery, they tore off. Otherwise, all good.

My Advice

Recommend ordering iOpener kit for 5C or 6 and above, because pulling the glue strips out is tricky. They can easily tear off, in which case the iOpener kit comes handy.
