iPhone 4 and 4S

[uncleruss]

Hi,
Just posting to see if anyone else has had problems with the new iPhone 4s.
Today I struggled to connect to the network on 3G and my battery went from 100% to 0% in 5 hours with little use!
Anyone else had problems or have I got a duff phone!!

Mines fine, used sat nav for 2 hours today as i was going somewhere, been browsing which i think is really fast, been using siri, and just got home and still got 53% left

[uncleruss]

Think it's duff phone! Will give it a good charge overnight and see how it goes tomorrow.

Mine has been okay so far. A big drain this morning although I was syncing then updating all my old content from iTunes, then about 100 updates came through AppStore

Just tweaking all of the little things I had on my old phone now - screen brightness, swapping email over from push to pull, knocking off unimportant app location services etc.

Charge your handset as much as possible especially in the first couple weeks, your battery has to become conditioned, and you definately aint going to know if it goosed after 24 hours.

Yeah buts it's not just a battery problem. Internet only connects for about 2 mins then it loses the server, going to try a full restore just incase it hasn't been set up right

Full restore is a good plan, and don't restore from a backup either, at least for testing purposes.

I wasn't enamoured with my battery life today. Been home all day and when I have used it I've used 3G instead of my Wifi as this is typical of my work usage.

From 9am to 4pm it went down to 21% and I wouldn't say I was using it heavily.

I think it will get better with a full restore though. I've seen this before on the iPhone 4.

I'm having the same issue .. Battery lasted 3-4 hours with little use .. It was also constantly very warm, even on charge. Phoned apple and they said It shouldn't get warm on charge.. So done some testing today and it's the mobile data usage setting .. I left it off and surfed and it stayed cool ... Turned it on and 5 mins later I can feel the back of the phone warming up even though I'm still connected to wifi .. I've turned iCloud off and limited the notifications to 6 or 7 apps. I turned mobile data usage on at 9:15 il see how long the battery lasts and report back its down to 97% at the moment

I charged my phone last night,  all night,  the funny thing is after a night charging,  didnt go past 97%.  so left it charging and its now 100% god it takes a while to charge.

My battery life is pants so far too, i think it just needs a couple of full cycles. But barely lasts 6 hours with light use and brightness very low.

It was 98% when i went bed and i woke up and it was on 30%.

I've now turned siri and wifi off so i'll see how that helps.

Try turning off iCloud, is a real bettery killer

[mtviveiros]

I am having the same issue. I reinstalled the software, but the problem persists. The same thing happened when I upgraded from 3G to 3GS a few years ago...

I think iOS 5 adds a lot of battery draining notifications by default because of the new notifcation centre, make sure that any of the various webapp checks are disabled since they may be checking the internet very regularly, which may also make your internet fairly slow and intermittent too

[mtviveiros]

I turned off most of my notifications. The batrery life is still a major issue. 

[palitsyn]

There are a few things that kill the battery.

1) Weather and Stock widgets in Notifications

2) Location Services for Reminders

3) Not sure if Ping is still an issue, but I disable it in Restrictions anyway

4) Disable spotligght search for anything you don't actually use

5) And if you think you can chat away with Siri all day, then that's not going to happen

I have written a blog post about it and the same techniques still work for 4s with iOS 5.

[mtviveiros]

good job on the weather notifications - am going to see what happens with it off

[a_ukboy]

Anybody tried turning off icloud? worked for me and left all notifications on, currently battery on 28% and been off charge since 8am yesterday! before i only got about 12 hours with icloud on..

[mtviveiros]

It seems a bit ridiculous to turn off the feature that is this model's unique selling point

[palitsyn]

I have iCloud on and it's not causing any issues for me.

[palitsyn]

For those who are still having battery issues try the following:

1) Delete your MobileMe account
2) Delete your iCloud account (save data on the phone)
3) Do a hard reset
4) Set up iCloud and MM again.

5) Go to settings - Genaral - Siri - Raise to speak - OFF

6) Go to Settings - About - Diagnostics & usage - Don't send
