Q: iPhone 5 battery draining very fast

Wow. That's excellent!

In my case I did go out to the world of cellular data for a couple of hours.

My fix:

Ok, this has been talked about a lot. My solution is: settings>>>mail, contacts, calendars>>>fetch new data. Then turn OFF "push" and set fetch to "hourly" or "manually." I think the push feature with the iOS6 is the killer. Perhaps this has been fixed with iOS6.0.1 but I haven't installed it yet. I now have no less than 70% at the end of the day under normal use.

Try this and let us know if it works!

I thought of that too, and it may help with certain people depending on their mail load. But I have 7 accounts - 2 are set to push and 5 are set to retrieve manually. It doesn't seem to hurt the battery that way.

Click advanced under fetch new data and you'll find a hidden iCloud setting that's set to push. Just turned this to manual.

What a sneaky place to put it!

Yesterday I installed Ios 6.0.1 and recnarged battery to full, i unpluged at 14h20 and used normally...today at 7h05 my battery is 90%...I hope that for me 6.0.1 solved my battery drain, i want to see when i need to recharge it...

Another update for you guys.

Today I went out and used 3G for 80% of the day and back home wifi for 20%.

I got a good 8 hours and the battery finally died.

Overall the battery is definitely better for me in 6.0.1. It seems its not fixed everyones issues, which proves there are multiple issues.

Definitely try ensuing push is off.

Installed 6.01 Thursday night, charged while I slept and started Friday with 100%.

I spent 11hrs in 4G/LTE areas (mostly 4G) while I was at work and my hour commute back and forth.  The rest was spent at home in my dual band wifi.

My conclusion?  The patch made ZERO difference!  At 1% remaining I was at 5hrs 27mins of usage, nothing different than the last month of use.  I think most people are imagining a difference with the patch but are probably just disabling everything and only on wifi.

I let it die, left it dead for 1.5hrs then plugged it in today to full charge, we'll see if it makes a difference but I highly doubt it.

In short the patch does nothing for this issue and I'm further disappointed in Apple.  Ill give it till 6.1 but if its not fixed with that then I'm calling it quits.  Ill be stuck with the phone, but I won't be buying or recommending any Apple products to anyone.

That's a little ignorant dude.

I haven't imagined anything. I have been monitoring my battery like a hawk. I am fully aware of what's on and off at any one time and my tests have all been pretty controlled.

For me, 6.0.1 has made a difference, quite a big one. For you, it hasn't. But I'm not going to tell you that you're imagining it, just because it's fixed for me.

Clearly there are multiple issues at play here.

There must be different issues at play here. My wife's phone and I had the same problem with the battery just draining.  I just deleted all settings and content on both phones and did a restore from the cloud.  Well my phone has been working awesome and the battery is not a concern anymore, my wife's is a different story. He phone still is draining fast so we took it to the apple store and reset everything and created it as a new phone. She did lose lots of stuff and had to redowload all her apps. Now tomorrow will be another test to see if that option worked. I'll keep you all posted.

After my previous spost, I went to get a swap of the iphone, the new phone behaved exactly the same straight out of the box at the store, showed it to the Manager who stated that 3-4 hours is normal use on 3G with this phone???

According to the Apple specs listed here:

http://www.apple.com/iphone/specs.html

it says:

• Talk time: Up to 8 hours on 3G
• Standby time: Up to 225 hours
• Internet use: Up to 8 hours on 3G, up to 8 hours on LTE, up to 10 hours on Wi-Fi
• Video playback: Up to 10 hours
• Audio playback: Up to 40 hours

That certainly sounds different from what the manager stated. Surely he can refer to Apple's own spec page?

Thanks Doug, he says those were optimitic figures, asked me to wait for 6.1 and swap again...

Very frustrating, I can only get 3-4 hours out of the phone if I leave Cellular Data on...

It might also depend on the carrier. Not sure. I am currently getting 8.5 hours to 9 plus hours. But most of the day I'm on wifi and only outside a few hours per day. And my carrier is probably different from yours (AU in Tokyo).

Thanks..I am on Smartone Hong Kong, when using WIFI I do get about 10 hours but not even half of that with 3G. I told the Manager there that some carriers in the US had provided a fix for their phone (Verizon)...The guy had no idea what I was talking about. They are so called 'Geniuses', please....They have no fix, dont understand themselves what is really going on and they just tell customers to be patient.

You have to ask 5 "geniuses" and then take the average of their answers.
