20 - 30 minutos
The iPhone battery was basically dead. The phone would shut down within 5 minutes of app use, or 20 minutes of non-use - even though the battery icon would show that the battery was almost fully charged. I had to keep an external battery handy in case I needed to use my phone on the go.
The repair was successful, but slightly harder than I'd expected. I had a difficult time getting the screen off, but the directions said to expect that, so it didn't worry me - but I did eventually have to seek out someone with manly strength.
Once I got down to the battery, I also had trouble getting it to dislodge. Thanks for the tip about the hair dryer. It did soften the adhesive enough for me to get the battery out.
The thing that worried me most about the repair were all the tiny connections. First I was afraid I'd break something as I tried to disconnect everything. And there was at least one connection that I thought I'd never be able to slip back in place. I couldn't tell if it slid in far enough to actually reconnect, but everything seems to be working fine now, so I guess it did reconnect properly.
Thanks for the easy-to-understand directions. I particularly appreciated the hints and notes about what to expect and potential problems to look out for. It made it seem as if someone was talking me through the repair, not just reading from a manual.
The only advice I have is regarding step 4. It was hard to tell where to insert the spudger to release cable 1. I saw three cables on the phone, but couldn't see multiple cables in the picture. I wasn't sure if the cables were all part of one connection, so I was afraid to dislodge the top cable. It seemed obvious in hindsight, but given that this was (1) the first cable to disconnect, (2) the screen was still connected and being held at an angle, and (3) the directions warned that damaging the connector would mean the display would have to be replaced, it would have been helpful to know about the muliple ribbons. Maybe the directions could say "(UNDER THE TOP RIBBON)" instead of just "(UNDER THE RIBBON)." But otherwise, the directions were great!
