You didn’t say if the battery was replaced at all after it died..the phone won’t work without a working battery even if it is plugged to the charging cord. What sounds concerning in the the red screen you say it shows when the phone restarts as that is usually associated to a hardware damage that would be too costly to fix for a 5S given today’s prices for a used one. If you want to try a restore you can do it with any PC or Mac, just download iTunes, launch it, plug in the iPhone e put it into restore mode and iTunes will do the rest if it’s just a software issue. In case of a hardware issue the iPhone will likely stay stuck in restore mode until fixed.
