Is there something about the way lemmy works that is causing Sync to chew up so much data? I never saw this kind of usage on Reddit.

By any chance are you watching an absurd amount of porn lol?

[โ€“] StarAD@lemmynsfw.com 9 points 1 year ago (1 children)

Actually no it isn't. Don't watch that here. Other than the random gif someone posts.

[โ€“] CrayonRosary@lemmy.world 62 points 1 year ago (1 children)

Um, we can all see what instance you're from...

Only have 131 MB... oh ur on lemmynsfw!

[โ€“] StarAD@lemmynsfw.com 2 points 1 year ago (1 children)

I mostly scroll all so don't know how being on NSFW would matter.

[โ€“] extant@lemmy.world 2 points 1 year ago

Because when it's NSFW it's probably an image or video which uses more bandwidth than text does, so if you're scrolling all those images and previews need to be downloaded and if it's prefetching more than just a thumbnail while you scroll you can end up with a lot of data transfer.

[โ€“] SaintWacko@midwest.social 27 points 1 year ago (2 children)

206 MB here. Wtf have you been doing?

Lemmynsfw probably

[โ€“] StarAD@lemmynsfw.com 1 points 1 year ago

Just scrolling through all. Nothing different from Reddit.

Not that far off from mine! Interestingly, my Sync used almost as much as Meet (which I use daily for video calls).

I suspect it's mainly multimedia data, like high-res images. Maybe Lemmy serves higher-res images compared to Reddit? I also recall seeing some discussion somewhere were Lemmy instance admins were turning off server-side image/thumbnail caching, so as a result you could be directly pulling the high-res images by simply scroll thru your feed? This is just a guess though.

Unrelated but TIL about TachiyomiJ2K.. really loving the j2k UX over the base...

[โ€“] fiasko@lemmy.world 4 points 1 year ago (2 children)

Unrelated to the post, but how did you manage to rack up 32GB for tachiyomi? Do you just read a lot? I don't think I've ever cracked a gig.

[โ€“] d3Xt3r@lemmy.nz 2 points 1 year ago

Indeed, I read a lot. :) But in addition to manga, I also read a lot of manhua/manhwa, which take up a lot more bandwidth than manga since they're colored.

I think you meant to reply to @d3Xt3r@lemmy.nz

But I agree with you lol

[โ€“] Appoxo@lemmy.dbzer0.com 7 points 1 year ago (1 children)

My guess: Reddit was serving not high res pictures (thumbnails) while scrolling and only gave them when opening.

Instances would need to create a thumbnail and the actual video. This would require a smal-ish CDN and processing power + storage to save the multiple versions to, right?
Idk about NSFW but arent they just hidden? To my knowledge at least Sync only shows "NSFW" and a blank single-colored post for an NSFW post.

[โ€“] StarAD@lemmynsfw.com 3 points 1 year ago

You can hide NSFW previews but they are loaded in the background.

[โ€“] StarAD@lemmynsfw.com 3 points 1 year ago

I'm thinking similar. I have preloading hires images off and gifs set to WiFi only, but when I go to view an image it is already there loaded. Guess I'll have to turn off preloading previews and thumbnails also. I don't watch video here unless by accident.

[โ€“] MrGerrit@feddit.nl 7 points 1 year ago

I'm on about 18 gig since 1st of August and I watch a lot of porn, memes and gifs/vids. I'm also a lot on sync.

You even got me beat, here's the ๐Ÿ‘‘, king!

[โ€“] limerod@reddthat.com 6 points 1 year ago

Mine is under a Gig and I actively use sync to browse lemmy. Maybe, you have enabled preloading for videos, etc.

[โ€“] agent_flounder@lemmy.one 6 points 1 year ago

Interesting. Mine is around 50mb for the last month.

[โ€“] GreenMario@lemm.ee 5 points 1 year ago (3 children)

Deleted Sync due to massive battery usage. 20% avg vs 10 for jerboa.

My guess is ads.

[โ€“] WestwardWinds@lemmy.world 10 points 1 year ago (1 children)

I think it might just be a bug or weird optimization issues.

And I'm pretty sure OP has that much data use because they're on lemmynsfw. Not only are they consuming a lot of media content, lemmynsfw admins have been turning off caching for images so he's fetching the linked media every time. I only have 1.06GB used since August 2

[โ€“] CrayonRosary@lemmy.world 2 points 1 year ago

If the cache contains the same image as the link, then how does that factor into the equation? Caches don't magically save bandwidth.

[โ€“] gridleaf@lemmy.world 7 points 1 year ago (1 children)

I paid the ~$3 for a month of pro, so no ads, and it still eats up my battery. I'll have to stop using it until it's resolved.

[โ€“] GreenMario@lemm.ee 7 points 1 year ago

Glad it's not just me. I like the app but I like my phone staying alive too thru a work day.

[โ€“] Kyoyeou@slrpnk.net 4 points 1 year ago

2.70GB, this month for me

[โ€“] JWBananas@startrek.website 4 points 1 year ago* (last edited 1 year ago)

I use it for hours a day, and I'm only at 347 MB total since install. But I only browse subscribed (and my subscriptions don't include memes).

[โ€“] Spacebar@lemmy.world 3 points 1 year ago

Lots of data use for me as well, but hardly any battery drain.

[โ€“] Voyajer@lemmy.world 1 points 1 year ago

It eats my battery but not my data

[โ€“] baruchin@lemmy.world 1 points 1 year ago (1 children)

OMG! In what time frame is that? That's way too much.

[โ€“] hardly_alex@lemmy.world 6 points 1 year ago* (last edited 1 year ago)

Check their instance!
