iPhone 4 battery drain due to excessive data usage since network issues were "fixed"

[alex_morley]

I have tried speaking to an O2 Guru (both online and in-store) and the Twitter account about this, but have received no solutions.

Since the network issues (which affected me on Friday) were fixed, my iPhone has been running out of battery from a full charge within 4.5 hours.

I tried switching off Location Services, Wi-Fi, Push Notifications etc. but nothing helped.

As a last resort, I looked at my data usage and realised I was using approximately 1MB of data every 10 minutes, while not even using the phone.

On further checking and with a little experimentation, I found that switching off "Push" from my emails solved the problem. My phone downloads sensible amounts of data and doesn't run the battery out.

However, this is clearly not a solution as it means I'm not getting my emails as I need, and it wasn't a problem before the network issues were "fixed" on Friday night.

I have also since heard from two friends who are having exactly the same problem.

Please could somebody at O2 look into why this is happening?

Try to do a restore via ur iTunes.

Macblank, thanks for the reply.

Sorry for being a luddite, but what do you mean by "a restore"?

Do you suggest a full wipe and restore from backup?

[macblank]

No

Turn on pc and connect the phone
When the home page (as it were) loads.
You will a few stats and a load of tabs across the top.

(Um trying to remember!)

On that home page I'm sure there is an option restore the phone (just like u do for ur pc when it plays up)

Ok thanks, that's great and definitely worth a try.

I'm currently checking the battery usage under "Push" and "No Push" conditions but as soon as that's done I'll try a restore.

Thanks again and I will report back on whether it helps.

Thanks Adam.

It's been a while since I used iTunes as u may have guessed!

Gentlemen,

You are legends. I've done a restore (50 minutes ago) and so far the battery has only dropped 2% with push emails active.

I'll leave it an hour or so to be sure, but at the moment it looks fixed - many thanks.

[alex_morley]

Definitely seems to be fixed - thanks guys.
