I get a discount on my personal account through my employer (we're a major user of Verizon for corporate devices) which made the battery from Verizon only $20 (picked up two at that price!
). Looks like steveinil is also on Verizon (from prior posting history), so it may be worth logging into your account to see if there's a discount on the battery. Even if not, IMHO $29.99 (same as Samsung's retail price) is reasonable for a genuine OEM battery that comes in retail packaging along with a plastic carry case.
For sure. Genuine Samsung and Anker are both good choices for reliability.
I forgot about the plastic carry case, which is very nice to have when (like me) you are the sort of person who carries around a spare battery most of the time - so that's one plus in the "Genuine Samsung Battery" column, because the Anker comes without a protective case for the two batteries they include in the box.
So, extra battery, or carrying case for the one battery you buy? I chose one of each (I have a spare Sammy with a case, and 2 Ankers without, for a total of 4 batteries and I can carry one around with protection all the time).
I think if I was doing a 1:1 replacement of a battery like OP, I'd probably go with the Anker because there is no intent to carry around a spare, and if you switch out the batteries once a month or so you'll have a good battery for a very long time. If I was looking for a spare battery to carry around with me everywhere, I'd go for the genuine Sammy for the protective case. But that's me. You can't go wrong either way, really, and we're not talking earth-shattering amounts of cash here.
But it's a major reason why I still have my Note 4. Because on the Note 5 forum, this would be a very, very different conversation involving finding a reliable repair shop that can replace the battery without destroying the phone and whether it's even worth doing. Here? We can debate $30 for 2 batteries or $40 for one with a nice case. I love that.
