I bought this model to replace my old one, which was stolen, so that I could transfer a backup to it. But also because I was used to this one.
On my old one I couldn't do the latest update because of lack of space, so it's handy that this one comes with the latest update. Now I have to get used to the changes.
As for the battery, I had a bug once when I unlocked it; the charge level suddenly indicated less than 10% and then the phone suddenly switched off. After plugging in the charger, the charge level showed 35%. However, I've had this bug several times on my old model, and I think it's something specific to this model that must occur after several years of use.
Let's just say that it's identical to my old phone, so I don't have a problem with it.
As a little bonus, my old one had a cracked screen and it would have cost me too much to repair it, so I'm happy with the refurbished model I bought here.
I just have one small comment about the condition of the parcel, the cardboard box was a bit crushed as there was an empty space inside. The phone was in a cardboard envelope inside, so I was a bit worried that it might be damaged, but it wasn't. Taking into account the place of dispatch and the delivery time, I'd say that's understandable, so it's not too bad.
I think it might be useful to mention in the item details whether the original box is present or not.
