Well I finished the battery install in my 5S. One of the adhesive strips broke. With heat and carefully prying the battery up(discharged to 1%) I managed to snag the strip of adhesive with my tweezers and pull it out successfully! This is the second battery from IFixIt that I have installed in the phone. The first one lasted less than one year. My battery life app indicated that the battery had a high to very high wear level. As I was waiting for the battery to discharge I noticed it went from 40% to 1% in a snap of my fingers.
After the new hard start for the new battery, my battery life app is indicating a very low wear level of only 4%. Not sure if I will attempt to replace the adhesive strips that I messed up, but will call IFixIt to see.
I purchased this replacement battery kit at Fry’s.com. The new battery was slightly different in size than the old one. Particularly, the battery connector was bigger. A challenge to position it to reconnect.
Hopefully, my phone will make it to Sept/Oct. Fingers crossed.
No fault of the author(good job credit coming your way), but my adhesive strips were a bear to install. My tabs were two separate as opposed to one long tab. Of course, I messed them up by letting one of the aforementioned tabs touch the adhesive strip. I had to use some double sided tape to finish the install. At least my iPhone 5S is working!
