Strong convergence for constant norm sequences

Question

Let $E$ be a reflexive Banach space and consider a sequence $\{x_n\}_{n\in\mathbb{N}}\subset E$ weakly converging to some $x\in E$. Moreover, assume that the sequence satisfies $$
\Vert x_n\Vert_E=1 \quad \hbox{for all }\,n\in\mathbb{N}.
$$
Does that implies $x_n\to x$ strongly in $E$? I know that weakly convergence plus $$
\limsup\Vert x_n\Vert_E\leq \Vert x\Vert_E,
$$
implies strong convergence, so I would like to use something like that. On the other hand, I don't know anything about the norm of $x$, and I think that this is not true in the case of the weak-* topology. I mean, for any such a Banach space, there always exists sequences of constant norm weakly-* converging to zero.

Answer 1

No. For instance, the canonical Hilbert basis $\{e_n\}_{n\in\Bbb N}$ of $\ell^2$, as a sequence, converges weakly to $0$.
