Hi all, thanks for all the advice given. I have ended my day out today and so far I have only used 28.7MB as stated in the "Current Period" for Cellular Data Usage. I think it's pretty difficult to pinpoint the TRUE culprit as I was super conscious of my data usage today and did not use as many apps as I usually would on a daily basis.
Used WhatsApp, checked some mail, searched for some accounting terms on Safari and really light gaming before sending out 1 SnapChat. Didn't even dare to scroll through Instagram until I reached home to use Wi-Fi!
I called Singtel this morning asking them to analyse for me which day did my data usage spike but they said they can only do that once my current month billing cycle end - idk but it sounds like an excuse to me; they probably hope that I exceed so I can pay them more $? HAHA. Anyway even if they can only check next month, it would be pretty useless since by then I would have either:
1. exceeded usage already or
2. managed to stay within 12gb by scrimping on data.
They just gave me additional 1GB just for this month to "monitor my data usage", so as of now I have 1.6GB to span my remaining 18 days. I divided and only have about 88.8MB per day. But after today's low usage of 28.7MB, I can rollover unused data to the remaining days.
One discovery, if any of you bros use SnapChat, is that it could possibly be the biggest culprit since out of the 28.7MB, it has used up 13.6MB! This is just by loading 5 of my friends' Stories! I always had the impression that these video-sharing apps would apply some sort of compression algorithm on the videos before sending them? Doesn't seem like the case...
@paul02: I haven't posted a photo here before so I decided to list them out instead until I learn how to post photos.
Breakdown of data usage for 16 Mar 2015
Snapchat: 13.6MB
Twitter: 4.4MB
WhatsApp: 554KB
Safari: 4.1MB
Settings: 31.9KB
My Singtel: 22.8KB
Mail: 1.6MB
Dropbox: 666KB
Brave Frontier: 1.2MB
Alien Blue: 109KB
App Store: 127KB
VSCOcam: 202KB
System Services: 1.8MB of which "iTunes Accounts" used 1.1MB.
These results may not be conclusive since I usually use more apps than these daily. It's just that due to this "data exceeding issue", I now only open apps I deem essential.
@Slim123: I don't use FB on my phone, so I never have to deal with the auto-start options
@Corny_Cow: I was lucky to keep my 12GB data with 4G VAS! Now I understand the pain of 2GB/3GB/4GB data users. I definitely cannot survive on those plans. I used to only hit max 6GB+ on my 5s before changing to my 6 Plus. There were people saying that the iPhone 6/6 Plus used more data and this is true, judging from my recent bills that hit 10+GB each month. Only for 1 month did I hit 11.6GB.
That's why I find this month's usage really shocking because I use my phone as I would every other month.
11.35GB in 11 days is crazy. Yes, it can be achieved probably through streaming of HD movies or TV shows using data. But even I would know better than to do that instead of using Wi-Fi!
