You can actually get an iPhone 4S replacement battery + tools to change the battery for less then $10 dollars. Certainly a-lot cheaper than replacing the whole phone.

Here is one for $9 http://www.ebay.com/itm/1430mAh-Internal-Replacement-3-7V-Li...

That's what I did.

Also updated it to iOS 8 GM and boy was that a mistake. Everything is slow, lot's of bugs.

I upgraded to iOS 8 on my 4S and found it to be a nice improvement. I'm not sure if I'll even upgrade my device during this cycle. It feels like it has plenty of life left to me.

Same. The betas where buggy and crashy but the GM works OK. I don't notice it being slower than iOS 7.

That's an incredible price. Thanks!
