Simple and efficient

내 문제

After less than 2 years of intensive use, the battery life of my iphone 4 was miserable

나의 수리

You definitely need the liberation kit! Not only these pentalobe screws are infinitely small, Apple does glue them to the unit. After the unit is opened, the battery replacement is fairly easy (although Apple is very heavy-handed on the glue that holds the battery to the body. Be patient !)

내 조언

When removing the pentalobe screws, be aggressive and decisive. You have to get them out on the first try!
