How to check exact amount of data used?

[ronniejoe]

I have a few gb of data a month... just three gb a month. I don't use data much so rarely if ever go over it. What i do know is on the iphone, you can check your cellular data and it shows the current period of data being used. I have an old iphone SE. And once the month is over... i reset statistics so it would show me starting with 0gb of data.



So let say so far in the month i used up 568mb of data... it shows that. But when i use more than l gb of data... it would show say
l.6gb of data. Is there a way to know exactly how much gb i used? Like l.678 or l.698gb etc? I want to know exactly how much data im using to the MB. Is there a way to do this? Also... i also heard the iphone data usage is not accurate? Is that true or false? So i need to download an app for that?



Another thing is this. I recently was tethering my data with my laptop when my internet was out. I done this many times and when i do this, i make sure im not streaming something on my computer which would obviously eat up the data. But for some reason it kept eating so much data. I then went to the setting of turning off background refresh which did help. But do i need to turn off data for all the other apps such as don't have cellular on for my apps? Previously when i tethered on my iphone SE to my laptop... this never happened. I would rarely go over say 50mb an hour when i tether it on laptop. But recently.. it was using up like 50mb every ten minutes or so.

I haven't tried it. So, couldn't say how well it works. But the first three articles I came across. All recommended Trip Mode. An app for macOS which allows you to monitor data usage per app. More importantly. It allows you to lock down which apps are allowed data usage. It isn't free, but it's cheap.

TripMode - Save data, browse faster

Easily control your Mac's data usage on slow or expensive networks. Stop wasting money on limited data plans.

Further, I'd suggest using Firefox for web browsing in hotspot mode. Disabling automatic updates, just remember to update manually. Add-on updates are a separate setting. Then use an add on for switching user agents. To switch to iOS identification. That way you get lighter websites. I'd also utilize uBlock Origin and Privacy Badger to reduce ad loading. Perhaps even a script blocker to prevent auto play videos. Script blockers are a bit of a pain to use.

Although, I haven't dug much. There are probably all sorts of data saving tweaks in Firefox. Through add-ons and about:config. I just listed those I know of off the top of my head.

If you aren't using it. Use the Mail app for email (I prefer Thunderbird). Not the website of your email host. Don't download attachments or images automatically.
