回答“Did I get a cheap batterie?”You got a cheap battery. Oldturkey03's idea to troubleshoot it is also a good next step.
回答“My Ipad was dropped and now everything is blurry”Sounds like you damaged your LCD. It sits below the digitizer glass, so even if the drop didn't damage the Digitizer glass, the LCD is still very fragil. It costs around $50.
回答“Home Button stops working after bettery replacement.”When you open the 5s, you need to remove a tiny metal cover carefully, then carefully detach the home button flex from the plug at the base of the battery. When removing the battery, if you weren't able to use the white ribbons to remove the adhesive, it's really tough to un-stick. Prying the battery up may cause you to lean on, bend, or break delicate grounds or components.
回答“No power after battery replacement”Did you put the insulator from the original onto the new battery plug?. If not, this can cause a short when touching the metal shield screwed on over it. Also you may need to check the Lightning port, to see if that may also be an issue. As always, try with a different cord and different points of charge to verify it's not any of those things.
回答“Can this device support Blu-ray?”Nope. It would clearly say Blu-ray on it.
回答“iTunes Error 53 - Please help!”Error 53 is tied directly to the Touch ID sensor/home button. This will come up when you change a screen and either don't switch the original button over, or kink/rip any part of the cable going under the metal tray or the button ribbon itself that connects to the long tray ribbon near the home button. It will be impossible to update without the original button. source: tech
