请问大家下列句子怎么改比较清楚地道

可以修改如下：
With the hand-held equipment coming into fashion,the power consumption problem becomes more and more apparent,manifesting itself both in limiting the equipment’s capability of working non-stop and in bringing about the overheating problem.


解析：
with 是介词,后接名词短语,所以谓语动词come要改为coming.
equipment 是不可数名词.
“问题变得越来越重要”不太合理,应该是“问题变得越来越突出（或明显）”.
Not only because ...属于原因状语从句,不能单独构成句子,需要与主句配合才完整.（Because...单独成句的话,通常用来回答Why.）

你的句子有点蹩脚，下面我为你提供简洁、地道的意译：Just　keep　your　eye　on　the　ball．　Never　mind　the　difficulty．　Sooner　or　later　it＆＃39；ll　get　resolved．Keep　your″ye　on　the　ball是口语，有不走神，不被．．．扰乱，集中注意力，坚持下去等意思。希望帮到了你，满意敬请采纳，谢谢。我是加拿大...

With the hand-held equipments come into fashion, the power consumption problem becomes more and more important. Not only because it reduces the continous using time of the equipment, but also because of the serious heating problem it brings about.
就加了s continous of ,其它没错误。 很规范，通顺。
