I replaced the battery a couple months ago, as it was dreadfully inadequate. Generally, I have a good connection from xdrip, but there are times like yesterday that try my patience. I don’t want to buy a huge new phone-I like the size of the S7–otherwise I’d have already replaced it.
EDIT: Since I replaced the battery, it overheats and warns of an imminent shut-down, when used in direct sunlight on moderate days such as when it is in the low 80’s (or less). I don’t recall that happening with the original battery unless it was very hot outside. I may be forced to replace the phone but with the newer OS, I won’t be able to run a compatible version of xDrip that works with my Gear 2 watch. THAT will be a bummer as I’m quite used to seeing my CGM data on my watch.
