With a limited budget my choices are limited to Z3+, Z5 & X Performance (due to all being waterproof). In all of their current Android Nougat 7.0 update which would you guys recommend right now in terms of battery life (& standby), camera speed/performance/quality (more warmer photos, lower noise in zoom & better low-light), memory management (apps not having to reload) , heating issues and speakers quality? Please comment & advice. Thanks.
