Samsung Faulty Battery on S7 Edge!

<p>I can't believe that Samsung uses such useless parts in their mobile devices. I own an S7 Edge which is under a year old, and the battery life is pathetic! I've even removed chatting apps like BBM and Whatsapp to see if that helped the batter, but it didn't! This phone is now only used to make / receive calls so I literally only unlock it a few times a day yet the battery doesn't last a day. Actually some days when I look at my phone at the end of the day, it's sitting at 70 some odd percent, yet other days it doesn't make it through the whole day. And this is with the same usage! This happened on my previous Samsung device which had to be replaced after I complained numerous times. This is such an unreliable phone for my business and am realising that Samsung as a whole only makes unreliable devices!</p>
