Q: iPhone 4s Battery Life?

My bad, i meant to type 8.5 hours compared to 200

I think I found a solution... just switch on Airplane mode. The battery life improves dramatically! (I'm kidding, of course).

But I'd like to jump in and add to the voices. I too am noticing drastic battery power loss. Confused me at first. After using the phone heavily I noticed I had to charge right away. Chalked it up to putting the phone through its paces.

The next day, I had a full charge at the start of the working day, didn't use the phone at all. Had a mere 38% at the end of the day without touching the phone. Wondered if I had forgotten to charge it. My iPhone 4 that I bought right hot off the presses had long lasting power.

I still enjoy the iPhone 4S. It's part of life now, the iPhone in the pocket. It's not going anywhere. I just hope there's a fix not to far away (so I can get rid of the anxious feeling of wondering if the battery will die at a critical moment).

Hi everyone! i recently bought a brand-new iPhone 4 (not 4s). The thing is that I have noticed that the battery does not lasts much. Last night I left the phone in standby mode with a 88% of battery, at about 2.30 am (ALL apps closed and locations off), and woke up this morning at about 9.30am with a 64% of battery. Is that normal?Because I understand that in standby mode the battery should last a much longer time than than. Also, when using it normally (navegating for 2,3 minutes and a couples of texts) the battery life decreases in about 3% (only in 3 minutes!). Normal again???

I have also noticed that in the Settings>General>Usage menu this morning it said the time since the last full charge, but now, all the sudden that info is empty, as in the phone has never had a full charge. What does that mean?

My concern is that i have read and asked other friends with iPhone 4 how much the battery lasts for them, and in their cases it has a much better performance. I dont know if my battery has a problem.

I went to my mobile carrier and tried to change it (Im still in a 7-day full warranty), and they refused to do so, allegating that "it is normal for the iPhone 4 to drop that quickly". So i'll like to know if they are, in fact, right, or if i should go again and tell them to change the phone.

Thank you very much!

PD;i already updated the software to the iOS 5

Well, mine appears to be tied to my Exchange e-mail. I restored my phone this morning, and restored it as a new phone, which completely reloads iOS 5. Battery was 100% or in the high 90s at that point. I didn't install any apps, just exchange email, gmail, and verizon mail, the latter 2 set to check every 15 min, the former (exchange) as push. Battery life is draining NO LESS than 10%-15% per hour. I delete gmail and verizon accounts, no change. Finally, about an hour ago -- when battery life was at 67% -- I deleted my work (exchange) e-mail. An hour later, the battery life is 66%. So I think in my case, it seems to be tied to my work e-mail. Importantly, I did not receive any emails during that time period, nor did I have any calendar reminders or such. I can't quite understand why it does what it does, but that's definitely it.

Importantly, though, a coworker of mine has the same setup as I do on his new iPhone 4S, and he has no problems. He probably has far less emails and far less contacts, but still...that's a huge problem. I'm going to see if Apple Care can figure this out, because right now I have a very expensive and shiny cell phone/text messaging device/clock that can't really be a smart phone.

I think I've read some posts where corrupt contacts can cause this type of problem. I wonder how you might be able to identify such things...    

We hope Apple find solution for this issue soon.

Last year Antenna issue..this year battery..

hope next year we won't have any Major Issue with iphone 5..

Wait till we get official words from Apple for this issue till then try some alternate methods to save battery at : http://supportany.com/2011/10/ways-to-increase-iphone-4s-battery-life/

Having read nearly all the messages in this thread, I have come to the conclusion that no-one has a definitive answer to the iPhone 4s's battery issue. And that, for now, includes Apple.

My own experience is this: my girlfriend and I both bought out first ever iPhones last weekend. 16gb, one white and one black, through T-Mobile in the UK.

Hers has shown to have a much better battery life than mine. Neither of us use iCloud, but I still have MobileMe, and sync my contacts. calendars and emails. She has no MobileMe. Despite me doing all the things suggested (turning off just about everything that makes this a smartphone), my battery life is still siginificantly lower than my girlfriends'. And they key thing here is, that she has almost everything turned ON.

So I'm wondering ,why the difference? Could it be the 'corrupted contacts' theory? She had no data to sync. So could that be a cause?

One other difference has been that I work from home, where the 3G connection is extremely inconsistent. In fact, 2G is pretty weak and results in the phone often displaying 'No Service' but then a minute later, showing a 2 or 3 bar, 3G connection. My girlfriend gets a strong 3G signal, all day, where she works. Could that inconsistency of 3G (or even 2G) connection mean the phone is not constantly trying to get a connection?

I don't know.

What I do know, is that two identical phones are behaving very differently. Who knows what's causing this? How about the colour of the phone! I'm joking, but unfortunately I'm not laughing about this.

Come on Apple, I think it's about time you spoke to your millions of customers.

Please?

Try to disable cellular data (settings, general, network) and see what happens... the phone will still accept and make calls.  Basically, it turns your iPhone to a dumb phone.  If your battery life improves drastically, it is obviously a problem where the iPhone is sending or receiving a lot of data thru 3G.  If this is the case, that means your phone bill may be humongous until you can track down the problem.  If I disable cellular data, my phone battery strength drops from 100% to 98% overnight.

Why exactly is anyone underserving of a phone because they post their battery life issues, which hopefully will assist Apple in pinpoining the problem and developing a fix? What an inane and useless post.

If you couldn't grasp the irony, and you think Apple needs you to figure out the issue, then you're truly a Apple user, friend.

Clicking on my name will allow you to read my other posts, if you need more background.

I like to confirm my battery issue still remains after having removed the duplicate mail box and disabling calendar from mail and disabling calendar notification.

The problem is still at large..

My stats

Usage : 56 minutes

Standby : 2 hours

Battery : 89 %

This is after a full battery charge session.

Note : my usage only included some occasional Siri usage, receiving emails as notifications to this discussion.

LOL, yes, I see that all of your posts are inanne and of no use to this discussion. Thanks for enlightening no one.

Sad and funny that you have that much free time on your hands.

I am having the same problem with my iPhone 4 running iOS 5.

Here are my specs:

• 32 GB iPhone 4 running iOS 5 (5.0 9A334)
• AT&T user (Carrier AT&T 11.0)
• Model: MC610LL
• Modem firmware: 04.11.08

Problem Summary:

My iPhone 4's battery life is consierably worse than it was when it was running iOS 4.x. It's going from 100% to <20% battery life in as few as 4 hours. I'm outside of the hardware warranty, but since the issue only started when I upgraded to iOS 5, I'm hoping it's only a software issue.

Attempted Resolution Steps:

Here's what I've tried so far to isolate the problem, with no success.

• Disabled Wi-Fi sync and left it disabled throughout the rest of the tests listed below. It had no impact on extending the life of the battery.
• Disabling bluetooth -- had no disernable impact (fully charged battery hit the 20% mark at around 4:19 of running in standby)
• Disabling Wi-Fi -- had no disernable impact (fully charged battery hit the 20% mark at around 4:27 of running in standby)
• Disabling bluetooth and Wi-Fi -- had no disernable impact (fully charged battery hit the 20% mark at around 4:48 of running in standby)
• Disabling location services -- had no disernable impact (fully charged battery hit the 20% mark at around 5:21 of running in standby)
• Running the phone in airplane mode with Wi-Fi disabled -- (fully charged battery hit the 20% mark at around 5:32 of running in standby, though it's not very functional in this state so it's not a very viable solution, to squeeze out only an incremential increase in performance)
• Restored the phone and then applied backup -- had no disernable impact (fully charged battery hit the 20% mark at around 4:03 of running in standby)
• Restored the phone and reinstalled as if it was a new device -- manually added apps, content, etc. -- had not disernable impact on battery life, but took quite a while. I'm still sitting around 4:15 minutes before a fully-charged battery hits the 20% mark and it's only downhill from there.

If anyone from Apple or on the forums have any suggestions on next steps for troubleshooting, I'd love to know. As of now, I'm just wandering around with a dock connector cable and wall charger, hoping to find a power outlet wherever I go.

I haven't had any battery issues what so ever on either of my iPhone 4S, on launch day I got one white 16GB and got it replaced for a new one 4 days ago from the Genius Bar cause it had a rattling sound in it, both have exact same battery performance and none have ever drained on me. My iPhone 4 had some drain one time but it never returned after a normal restart

Location Services: ON (all of them)

Calanders: ON (all of them)

Auto Set Timezone: ON

Cellular Data: ON

Brightness: Auto (with the slider moved slightly to the left, over the "n" on brightness)

Mail Settings: Manual (for my Gmail & 2 Hotmail accounts, with the exception of iCloud account on push)

This is what its at right now: http://i255.photobucket.com/albums/hh156/inferno129/IMG_2701.png

Over half of that useage time is YouTube over Wi-Fi and at least 20 text messages are included in there, along with 20-25 mins of using a location based app with frequent reloads.

Restored from iCloud in the Apple Store soon as I got the phone.

Just found all those battery stats and serious higher level user condescending talk was quite boring... so I'm here to entertain you a little bit, and maybe to teach you a bit of humilty in the face of adversity

Off to the coffee shop with my new Galaxy S2, uncharged in the last 24hrs might I add... bbl.
