If I use my mobile phone data by hotspotting or tethering my laptop to it will it use up more than usual? I've been heavily reliant on my phone for internet over the last few months and have only used 50% of the data allowance with my mobile phone plan so I'm wondering if there's any advantage to getting a separate internet connection at the house I'm renting now? Is there any reason to not just use the data allowance with my phone plan? Well other than that the speed is sometimes a bit slower.
In general, will use more data when i.e. surfing on your computer vs surfing on your phone, I would say.
I‘ve never measured it but here are some points.
i.e. when you go to some main stream news portal on your computer, you see more advertisement (unless you use AdBlocker or similar) and those advertisements use also your data volume.
Many of the portals are adjusted to mobiles, so portal detect that you are connecting via mobile/tablet and you don’t get so much advertisement in the background, but more pop-ups that you close and that’s it.
Also it might happen that your computer pick up some upgrades and start to install them, if you have in your settings to automatically download updates. It can be turned off in the settings. So you might spend extra data volume on that to.
also in general when you surf on your computer and you are connected to your fixed line with, in general, unlimited data volume, and then you transfer to hotspot, people generally forget that they are on the hotspot and i.e. watch videos like they normaly do. So you forget you’re on actually your phone with limited data volume and do what you usually do on your computer.
in general, I would say that, yes, you spend more data volume when you hotspot and surf via computer, than to only surf via smartphone.
you can measure it in your settings.
Generaly phones have statistics and you can reset those statistics and see how much you spend one day surfing on your phone only and how much you spend when hotspot turned on and surf via computer and your phone.
