I jumped on the 3.0 bandwagon (and what a ride it was.) But reality is beginning to sink in and my battery now gets scorching hot (so hot I felt it through my wallet and pants) and dies within 5 hours in standby. I found these discussions on Apple's website: Topic : Battery hot after 3.0 update Topic : Battery goes down incredibly fast after 3.0 update? So far no real solutions. Some suggest turning off mail push notifications but I always had that enabled. I want to know what has changed. Anyone else experiencing these symptoms?
I have it to, The past 2 nights my iphone does not charge at while I sleep. It just becomes incredibly hot
My iPhone 3G is doing the same thing. It gets hot randomly after using a few applications. If I do a full reset, it goes back to normal but after opening a few applications again, it turns into quite the leg warmer. Hopefully 3.1 irons out this issue.
This happens on a mac from time to time. If I remember correctly, the general consensus is that its because of spotlight. So maybe on the iPhone, its 3.0 doing its indexing all your app names, emails, etc. To confirm this, you can: try turning off spotlight or someone can ssh inside the iphone while its hot to see what process is actually hogging cpu cycles.
Happened with my iPod touch 1st gen as well. Yesteray I restored it and put a backup back on it. Until this morning it seemed like I had my long battery back, but this morning is drained fast again. So I can't draw any conclusions yet, but I'll certainly follow this topic.
My solution It was push email that was the problem; specifically, a Microsoft Exchange account. I had disabled it about 8 months ago but it was attempting to sync every few seconds since 3.0 (even though it was still switched off in the settings.) I deleted it from my iPhone and problem solved. So that might be your burden: Microsoft Exchange. If that is not the cause of your issue, good luck but I have no more ideas.
Definitely not my issue. I never have push email on. I also plug my iphone in at night and leave it resting on a glass table. Last night it used up so much power that when I took it off the charger it died, and continued to die every time I tried to turn it on. It was blazing hot but it turned on long enough to say that my battery was dead. I placed my iphone on the cold tile of my hallway to bring the temp down. When it was cool enough to handle I charged it and haven't had another issue all day. The scarcity of the issue is what is bothering me. I have plenty of external power (an extra battery pack, a solar charger, and a wind charger) but I'd like to know that I can rely on my iphone
Don't rule out the possibility of a syncing bug just yet. Sync was not enabled for the problem account in my case but it was still attempting to sync. Perhaps that is the nature of the bug: the sync might be failing and retrying because it is disabled in settings... I don't know. Then again, the specifics of your situation do differ from mine. Restarting didn't 'solve' my problem. Another issue I had a few months ago that caused serious battery drain appeared to be a memory leak in Safari (I think it was or was it Mail... one of the built in apps was constantly running in the background anyway.) After a restart it was business as usual and I haven't experienced that again.
about an hour ago i noticed my iPhone was getting hot in my pocket and now none of my apps open. I press the icon, and it crashes back to home screen immediately, every single 3rd party app. WTF apple
So my issue is now officially fixed. I downloaded SBSettings from Cydia and turned off EDGE. Now my phone charges AND it runs cool too the touch just like it did before. I don't have a data plan on my 1st gen iphone and I believe the problem was that the device is constantly trying to connect to push services via EDGE to turn off Wi-Fi and conserve power. Just like a cellphone if you aren't establishing a connection it keeps trying until it finds one. Thats a LOT of wasted power and effort. Once I shut off the EDGE function everything is working even better than it did on 2.2.1. I'm not ready to give up my Prepaid plan and sign a contract. AT&T can suck it.
