Chosen Solution

I completed the iPhone 4s battery replacement with help from the iFixit.com repair guide - thanks! The phone is working. The only issue I had during the replacement was losing the bottom screw on the battery connector. I closed it up with the screw missing because the top screw seemed to hold the battery connector in place, plus, no real option. Is there any danger to a user or the device in leaving this screw unreplaced, if anyone knows? Thanks!

Not to my knowledge you shouldn’t have any issues the screw is just there to make sure battery stays down and dosent lift when dropped or hard bang.

Same problem

Mine won’t charge with this missing worked for a day or two no real problems and now cannot switch it on and can no longer charge however when it’s connected to charge it does light up
