Recently I replaced my iPhone 4s battery using the steps provided in this site. After I was finished reassembling the phone I plugged it in to charge. It start showing battery charging buy after 8 hours of plugged-Inn is still showing same battery logo screen with 2-3 red-lines. Than, now Apple logo will appear as if it is restarting normally. But it will only appear for 4-5 seconds before it disappears. Than it goes to same battery logo screen with 2-3 red-lines. It repeats coming and going about every 1-2 minutes. Apple Logo »>Battery Charging Screen »>Apple Logo»> Battery Charging Screen »Apple Logo » Battery Charging Screen…again and again…..Any suggestions?
It can be a faulty battery or the battery connector on logicboard is comming off the logicboard. Check if the connector stay solid on logicboard and ther is no damage.
