7. Huawei P9
Among the 26 tested smartphones, Huawei P9 had the lowest dBm value of 8.3 when used with the right hand. Luckily for P9, other two performances managed to put it on our list. The left hand performance was valued at 15.0 dBm, and data service was at -89.7 dBm. So if you are a righty, you should consider skipping this one. Nevertheless, when it comes to other specification of this smartphone, they can be quite tempting as it offers a 5.2 inch screen, Octa-core (4×2.5 GHz & 4×1.8 GHz) processor, 4GB of RAM and 64GB of storage. Alongside a dual 12 MP back camera, P9 is packed with 8MP front camera as well.
