There are some possible reason why your upload speed on smartphone higher than laptop:<br />- Maybe some components of your phone that are better<br />- Your laptop' wifi card uses the wrong configuration (2.4 GHz, 5 GHz)<br />- The phone uses fast solid state memory, the laptop may have a slower mechanical hard drive.<br />- The phone may have a fast new processor, the laptop may be slow.<br />- The phone may be new and fresh, the laptop could be bogged down with adware or background processes....<br />Good luck
