IOS-5 battery power drain issue

My phone is a 3Gs.

I let the battery run completely down and then the charger thinks the battery if full and won't let it charge. When I plug it into the usb port, it won't recognize the phone and put power to it. I am stuck. I would like to turn it on long enough to be able to adjust the settings recommended, but all it does is reboot in a continus cycle. I was dumb enough to try restore from iTunes and really screwed it up. Anyone have any suggestions?

Your post is about a power cycling issue, perhaps not even related to your upgrade to iOS5. This thread is about battery life issues, not iPhones that aren't charging. Try and use better basic comprehension next time.

Try this: plug the iPhone into a wall charger, leave it for 5 minutes, then return and hold the power and home button together for 15 seconds to reboot it. Charging functions should be restored.

Well, thanks for your response, Timothy. I have already done that, but I will try it again.

A little rough, aren't you?

You said "Try and use better basic comprehension next time.".

Golly, gee I figured with your superior powers, one could deduce that there are so many posts and threads on the various forums that I could not have found my way here without mentioning the iOS5 upgrade, but perhaps I should have. The phone functioned fine untio the upgrade. You probably were offended on my comment about Apple not being the company where I bought my first computer. You should know that my first home computer was the first one that was marketed by Steve Jobs, and I in fact was invited to a presentation where the Man himself presented the computer to the first few of us to purchase one, so you will forgive me if I may be a little senile, sonny.

PS. Steve Jobs is rolling in his grave over this.

Sorry for jumping aboard at the very last post, but I've noticed one thing (FWIW): my iPhone 4 battery lasts longer when I've recharged it via USB (usually on my MacBook Pro at home, sometimes on my PC at work) than with the power adapter plugged into a wall socket (I live in France, where we have 230V AC power). Has something to do with USB charging being "smoother" than charging off the main, or so I've read somewhere.

I found turning off "Reminders" in your email accounts is helping to stop battery drain in my case. Tried so many combinations of settings and this worked in my case.

Hope this helps.

Here we go. The solution is below. Hope it will work for you too!

1- Delete your email account(s) in Settings > Mail, Contacts, Calendars > Your Account > Delete Account

2- Reset Network Settings in Settings > Reset > Reset Network Settings

3- Reboot your phone by holding the sleep/wake (top) button then sliding to off.

4- Re-add the email account Settings > Mail, Contacts, Calendars > Add Account…

5- Turn push back on

This worked for me. Prior to doing this was going from 100% to 0% in less than 15 hours without using the phone. Now I am back to normal use, phone has gone from 100% to 99% in 30 mintes much more normal. A lot of the people saying they've tried everything don't actually list removing the email account from the trouble shooting. Clearly the new OS is struggling with the old email connections so try this please.

This also worked for me (I think - I tried loads of things but I think this is what actually got it).

Previously I had the phone on and drained fully in 4.5 hours (while in standby). The usage = standby time and so it was doing something constantly in the background.

Current standby is 1 day 17 hours with 5 hours and 26 mins with 16% battery usage left still. So as you can see a massive difference.

Again I think people are commenting on 2 issues here. One where the battery drains faster than they would like (ie in 24 hours say) and the main issue where it drains as per my experience in a matter of hours.

Hi

I am french and i have the same problem with an Iphone 4 with IOS 5.

This morning at 7 it was 100% charged and after an hour it was 80%.

Sometime the device is very hot. I turned off all the application WIFI Bluetooth Icloud and nothing has changed.

It is time for apple to find a solution to this issue.

Someone claims it's a bug in the iOS software and has to do with system services constantly using locaiton for setting timzone. Full details here...

Thank you!!!

So far so good.... Been using this settings since Oct 24th.

1. Delete all your email accounts

2. Do a hard reboot on the phone

3. Add back email accounts... reminders being off

Battery life is back to near normal. Giving me two days without recharging again, usage correctly showing the usage time and not equal to standby time.

On the sidenote, I have one of my email as exchange account and in my case that was causing the issue. Re-adding this account first time always threw error "Unable to ...." . Next day I tried again and it was connected successfully, turned the reminders off in this account and everything is back to normal...

Hope this helps!!!

I found my issue. I've tried all the recommendations, but finally narrowed it down to Good for Enterprise (horrible email app we are forced to use). However, not just stopping the app, but going into notification center, and stopping notification plus telling it None in alert style fixed it. Now I am back to full charge all day. If I turn that one thing on, or launch the app, I lose about 10% per hour like others. I still have iCloud on and most things re-enabled.

Hope this helps others.

I have never had to turn off anything in the past why the **** should i start now? If i had bluetooth and wifi on all day streaming music to my headphones from pandora and getting every push notification for every game and email and txt etc. why would i pull the wool over my eyes and start turning things off just because there is now a huge problem with the software. As far as popular apps go you might be on to something. My phone did not have this problem until after I updated 4 apps yesterday. (i would bleed to remember which 4 as they would be deleted already.) after i synced the updated apps this problem started.

Surprisingly I found that turning off iMessage saved a lot of battery for me.

I have to agree. While we should expect some extra battery drain when a lot of things are running, we shouldn't have to turn off most of the features of this amazing phone in order to be disconnected from a charging cable for at least some significant portion of the day. If we'd wanted a basic phone we'd have gotten one. But I did get considerable improvement with deleting my mail accounts, rebooting the phone, and setting them up again (but none is an Exchange account). Try that. It is an easy enough thing to do and it can help a lot.

Now if we can only get our 2G/Edge-3G toggle back (for those of us with AT&T GSM 4S iPhones). We miss it and the phone is using battery like crazy trying to connect to marginal 3G signal strength. And dropping calls.

It kind of blows my mind that people find this thread and don't even read it to see if a solution was found....

I'm glad to report that i'm now on 22 hours and 2 minutes of standby and still at 49% battery with 3 hours and 18 minutes of use. Mostly streaming music and the rest phone calls. I even used google maps to navigate once today. DO NOT CRIPPLE YOUR PHONES! I am using default settings on everything wifi bluetooth and location services are on, photo stream and find my phone. And i also found and added my exchange email account last night so it is NOT exchange based or any other app on the phone. Just do a Firmware level "black screen" restore using Itunes 10.5 and your problems WILL be gone. stop turning off features, you are carrying an iphone.......
