Massive Data Usage . . . TikTok, anyone have this happen?

We got the daughter a 365 day plan through Woolies which expires June 2021.
Last week she got a message that she had used all of her data.
So I went and checked on the data usage breakdown.
48GB in December!!!!!!
Every other month she's averaged 4-7GB a month.
So it was a huge shock that December was a blow out.
It did coincide with her getting a new mobile (Samsung A51) as a Christmas present which she got early 28th Nov.

So went through her mobile and found that TicTok (rather she) had used ~2GB+ a day of data.
I'm trying to work out how this could change so dramatically with the new phone as she was doing exactly the same stuff
with her old Samsung S5 prior to this.
Same settings and most of the use is when home and using our WIFI not the mobile data.
Data saving was set to on in both the old and new phones.

So this old dude is stumped as to what the hell is going on!

Anyone had a similar experience or any ideas as to what could have happened?

    Pretty sure its the resolution of the videos, if it was 480p on the s5 and went up to 2k on the new phone thats about 8x the data.

    You can check how much data the actual app has used in the settings. If it correlates then that's a lot of hours watching videos. Approx 1GB per 1-2 hours use which could increase with higher resolution screen/specs.

    It's possible data saver may not have worked and clearly wasn't connected to home WiFi.

    • They did….

    If it was a new phone, perhaps some of the updates were downloaded over mobile data?

  • You can specify data limits and force the phone to disconnect from 4G once the allocated data has been exhausted for the month. Background updates and HD videos are the biggest data hogs. I'm so stingy with data I won't even load basic images unless required and watch videos @ lowest resolution 140P on UTube. I'm in the extreme minority though :P

  • s5 must have been slow as.. with a faster phone you do more with it. you could chance to 3g only in the future to conserve data

    Not sure why. You seemed to have worked it out

    Ok so you know she used the data and you know it was used by TicTok.

    Looks like someone wasn't connected to wifi during the month of Dec……then ran out of data.

    She might do better with a plan. Telstra and iirc now Optus too both have removed excess usage charges and shape to 1.5mbps, which is actually fast enough for tiktok, youtube, and browsing anyway. Plus the unlimited calls and texts.

    • I know Vodafone has this feature on prepaid plans too.

      I agree. It costs the telcos 1/200th of (profanity) all to give you a gigabyte, the only reason why these arbitrary limits exist is to get you and everyone else in the habit of rationing data so the network doesn't fall over with everyone trying to TikTok at the same time. This younger generation has no idea how good they have it. Perhaps have a usable, albeit slow, data connection will teach your young one how to conserve their data?

    I would be worried less about the data usage and more worried about her screen time

  • Android has a "Data Saving" mode for mobile data. This will cut down the TikTok video downloads in half by reducing the resolution (from 70MB every 5 mins down to 30MB).

    Looks like your daughter may need to sign up for a paper run to pay for the new data!

    Delete tiktok, save both data and your daughter's mind from that absolute rubbish.

      omg i hate you DAD!

    No wifi at home?

  • Use a monitoring app like glasswire to monitor and report data traffic flow.

  • I'm skeptical wifi was set up on her new phone.

    But you're kinda in difficult situation, because your daughter habit didn't change and shouldn't be punished. Yet you have to get her a new plan and want to find out the root cause.

    Can she live without tictok outside home for next 5 months?

  • A lot of apps have the ability for a “low data usage” setting so tik tok may also have this?

    Edit: sorry I just read you have already done this.

    • Have a look at one of the kogan 365 day plans that give a monthly allowance. If she wants more gb per month then she can pay the difference between what you are willing to pay and what she wants to use. Or, she can only use tiktok on wifi.

  • If you can afford it sign her up to felix unlimited data for $35 a month.

    Why in the ever loving hell would you let your daughter use TicTok? Jebus…

  • turn off mobile data for tiktok.

    problem solved
