I've had my s7 second hand for a few years now and has been the best phone I've had so far. Unfortunately I think the battery is kicking the bucket. 2 hours n 7 mins and I'm at 51% this morning . What's a good upgrade via swappa or something else second hand $200 price range. Or should I just replace the battery on the s7? Can't decide, would like some input from the community.
