iPhone 6s burning battery and data

[Anonymous]

Hi,

I have just upgraded, I had an iphone 6 previously and now have a 6s. My average usage each month in terms of data was under 1gb with my iphone 6 - I have exactly the same apps etc as I restored the backup from my icloud on the 6s but have used nearly 3GB in 2 days!! Also the battery doesnt last anywhere near as long! Help!

Try checking this link - apparently Apple decided that using your data allowance instead of wi-fi was a good idea (which in principle if your data speed is better than your wi-fi it might be...) and turned this feature on by default.

It has a link to the Apple website with instructions on how to turn it off.

That doesn't sound good @Anonymous If you are convinced you haven't used that much data. Have you honestly not added any more new apps to the phone?

If you think it could be a fault with the phone then I would ask for it to be swapped.

You could give Apple a call and see what they have to say?

Thanks for this - I have turned Wifi Assist off (yesterday) but still seem to be using lots of data!

Hiya - thanks, I hadn't considered it being a fault with the phone so will see what Apple say.

I honestly havent added any apps!

1 To check what is draining the battery Settings> Battery scroll down hit clock to display on screen time as well as %

2 To identify the data usage Settings> Mobile Data scroll down to see what is using the mobile data

Hope that helps you track down the culprit as since my 6 - 6s upgrade not seen any strange behaviour

Did you do your restore via iTunes of over Wifi / Mobile data as the restore over mobile data can take a few days (such as restoring photos, etc) so could this be the cause?

If none of the above shows anything up or deleting and reinstalling the app (s) responsible if so a full factory reset and set the phone up as new. Don't restore from a backup, start over again - which will be fine consuming but could be worth it if it fixes the data and battery issues.
If that doesn't work then as previously suggested taking it to Apple is the next step.
