I had my old iPhone 5s battery replaced. The good thing is that I can now use the phone for longer. The bad thing is that the upper left portion of my screen is no longer properly attached and after highlighting this problem to Lovefone, the staff just said that "this is normal when you change batteries on old iPhones. The glue/rubber might losen when you take off the screen". Huh? I have my doubts since I haven't seen this happen when going through Apple's service. However, since the phone already is old I opted for the cheaper option at LoveFone. Cheap isn't always better.
