My 5s is killing batteries!!!!

[lthompson]

All of the sudden my 5s battery went completely dead. Would not take a charge. I replaced it and it worked for about a week and once again it killed the new battery.

Any suggestions?

My sister had this problem with her 5s. They ended up giving her a new iPhone 5s. Didn't have a problem with the new one. She just recently got a 6.

Edit: They being the Apple store.

Thats the likely scenario of "buying China crap" off eBay. Might wanna try an OEM battery, used if you want cheap.
