Consistent problem with iPhone 4S software

Hello! I have had issues with my iPhone 4S since the day I got it. I have been to the apple store more times than I can count and every time it's some stupid excuse or attempt to fix my phone. Well now I am out of warranty and they told me there is nothing they can do.

I have all kinds of problems, from battery issues to apps not working to the screen freezing on me, etc. Every time I go they tell me it's an issue with the software and reset my phone to factory settings. I set up the phone as new and then bring over a small amount of pics, music files and apps. I never restore from back up.

The most current issue is the phone drains to 1% battery and when I plug it in to charge, it acknowledges the charger but won't charge. The phone then dies and I am unable to turn it on for at least 48 hours. This has happened twice now. Apple ran diagnostics and said everything was fine and it was probably a corrupt file. We again reset it to factory settings and I was instructed to not bring over any files. I then used the phone for one day and it happened again. I also have not been able to back up to iCloud since I got the phone. The backup always fails.

I am desperate at this point and apple will not replace the phone because it is out of warranty. I never had issues backing up to iCloud or with my files on my iPhone 4. My husband plugs his phone into the same computer and has no issues with a corrupt file. Any thoughts or suggestions on what I should do?
