If unconfirmed for a specific period of time, do popular wallets remove transactions from the mempool? Are there some wallets where if your transaction is never confirmed, your funds are never returned?
How do the most popular Bitcoin wallets handle transactions stuck in the mempool with too low fees?

In general TX is removed after arbitrary time period (14 days for Bitcoin Core) or when mempool size is exceeded and space is needed for fresh TXs. For Bitcoin Core check this answer.
This answer is a bit short and only covers part of the topic. Could you perhaps elaborate? – Murch – 2017-09-20T20:19:23.950
Could you please specify which wallets you consider popular and would like to hear more about? – Murch – 2017-03-27T21:55:30.480
Sure. I don't have stats to hand but these are the mobile wallets listed on https://bitcoin.org/en/choose-your-wallet. How do their policies compare?

No I already use a number (GreenAddress, Airbitz, Bitwallet etc) I'm interested from a UX perspective. – Michael Folkson – 2017-03-27T22:17:15.640
I see. Perhaps this related question is of some use: What happens if your transaction is never confirmed?— In regard to your question, perhaps it would work better as "What methods can a thin client offer to resolve stuck transactions?", or you could limited the question to a specific wallet, to make it clear what would constitute a complete answer. Or maybe it'll just work fine. ;)
