iPhone 4 heat and battery issues

halcwb...yup. Next thing they will be suggesting is puttting on a tinfoil hat and standing on one leg with an arm up in the air.

Flogger..they do. ANd I have had my phone replaced twice. I'm either the odds buster or there's a flaw in that percentage. I think the fix is in the software and not the hardware.

Well, the external battery helps, but I want to read on my iPhone and am afraid it will run down too fast. I may use the 4S only as a phone and go back to my 3GS for reading and games. The problem is definitely Siri, which is also in beta format right now. But I haven't used Siri, so maybe there's stuff running in the background that I don't know about.I have an iPad,but it's a little heavy if you want to read in bed, which is mostly where I do my reading. I haven't had the problem of the phone overheating, but that's probably because I don't use it much. I should probably do more with it and see how it goes. I subscribe to Macworld. Maybe I'll contact them and see what they have to say.

sorry, i posted the wrong place

Thanks Lawrence 🙂 just did what you mentioned about the exchange mail setup and now it's back to normal...

Hello guys i have C3 serial with 9a405 only thing i did not try was factory reset, all other solutions are fail for me "mail accounts, siri, location services even turning off cellular data". I have %50 phantom usage %7 battery drop per hour on standby.
I notice some strange behavior; when i reset my phone settings to defaults battery indicator went up several percent for example %97 to %99 and it will be fine for half a day then i start to use some apps, it will back on fast drain again. "turning on-off wifi or location services does not make any differance" phantom usage is about %50 all the time after several hours of usage or battery drops under %60-%50 percent some how usage statistics returns to normal and i get %7 drop for all night.
My old iphone 4 with same apps and usage has no battery issues at all, i can walk with her for 7.5 hours with nike+gps and music on all the time.

You must do factory reset.

I do not want to make any waste effort. People claim it was also fail attempt but i will try it this week end and write here..

You can do it....but it will make almost ZERO difference. Buy a charger and take it with you wherever you go.

So is this really a production fault?? which apple keep us busy waiting for unworking patch? i do not want to belive this. My friend who lives in Bulgaria had the same problem, now he says 'after replacement' he can use his phone at least 2 days but an another friend changed his phone two times in England without success. I want to belive it is a dumb software bug. Apple please raise the wages of ios software engineers..

Those who does not have phantom usage yet have fast drain; Has any one tired external battery solutions ? are they drain that fast also? may be built in battery and charge chip fails.

I took my phone to the apple store and they happily replaced it. My new phone is currently hot as an oven and the battery is draining so fast that while plugged in it won't add a charge.

Also I'm pleased to report the NEW phone given to me has extreme crackling coming from the receiver when on phone calls.

What an absolute disaster. I am not happy.

Is it possible that they gave you a rebuilt one? Or a phone that someone else returned? Take it back and keep going back until you get a phone that works right.

Got new phones TWICE. There's no quick fix. It's a broken phone and software.

Since my last post, I took one further step. I turned off Siri. If I want to use her, I'll turn her on temporarily. Between that and the other stuff I did, I'm getting decent battery life -- not as good as old phone, but it stays charged for a day. I can live with that.

I've had my iPhone 4 for over a year now and in the last month when I run two specific features/apps, Waze and personal hotspot, the phone heats up. When I run anything else, it stays cool. Is there a particular reason why this would happen with this feature and app?

I've done a factory reset and have left it off for a few hours to see if the problem would go away, it hasn't. Any help would be appreciated before I go to the Apple store.
