So my battery has seen better days, won’t last a whole day (with very sparing use, I’m not a phone junkie) and sometimes dies at like 35%. I figured it was time for a new one. Ordered the best reviewed kit on amazon. The replacement process goes fine, and I get the phone all buttoned up and plug it into a charger… and it just sits there with a black screen, vibrating like it’s recognizing a power cable every five seconds. Now from what I’ve seen online, this has to do with a damaged display, or at least damage to the connection between the motherboard and the display. So I check the connection, nothing is damaged or kinked, but I disconnect and reconnect the cables and try again. Same symptom. I then reconnect my old battery (failing, but at least with some charge and known to work) and the phone boots right up. Is this a bad replacement battery? A battery that just needs to charge for a while to get up to a useful load? Something else wrong with the phone?
I got it working!!! I had the same vibration every 5 seconds & black screen after replacing a cracked display & plugging in my i-phone 5. I was so frustrated & spent over an hour re-seating all the ribbon cables several times over & everything looked good. Finally I took the advice of someone on one of these forums — held down the lower round button & the top on/off button at the same time, for 15 seconds until the white apple showed up on screen. I let go & it came alive!!! I was so thankful my prayer was answered.
Sounds like you have a back battery, try another one.
