I do KNOW this that a MAC laptop does NOT charge when it goes to sleep period. Wall charger is the only way I can get mine to last more than 21 hours standby but mind you whenever I do a reset all those numbers get askewed and starts fresh FINAL VERDICT >>>>> Battery is the weak-link in this device period, I don't care what others say........

Funny it worked.....the last time!!Now I am not sure what was working before they put a hole in my head!!!!

I now have a full charge (as evidenced by icon the power plug inside the battery icon) so we'll see if charging on my desktop PC makes a difference. I've also created a temporary folder within Outlook to store my e-mails for the day before I file them. It is a pain not to be able to move them to the correct folder immediately after I've read them, but it should give me a decent count of the number of e-mails I've received (translation: number of times my phone vibrates). In the past 2 1/2 hours, I've received more than 10 e-mails. Perhaps pull is the way to go. . . .

Well, you know you're going to have a crazy day when: (a) you don't sleep well and wake up earlier than normal; (b) you leave for the office about an hour earlier than normal, expecting to get a jump start on the day; and (c) you arrive at your office to find out that there was a brown-out the night before and, as a result, your servers aren't functioning properly and your telephone and internet service aren't working properly. Yes, that was the start of my hectic day.

I tell you this in part because on my way to the office, when I tried to check my e-mail, the iPhone just spun in circles trying to retrieve e-mail. Of course, at the time I did not realize the problem was that our Exchange server was not connected to the internet. By 8:30-9:00 a.m., all server and ISP problems were resolved. Needless to say, the rest of my day was equally hectic. I was able to take some notes the old fashioned way throughout the day, though. Therefore, on with today's report:

8:32 a.m.--I'm getting a low battery (20%) remaining warning already. Didn't I just finish charging the iPhone yesterday morning (less than 24 hours ago)?

9:58 a.m. I had better start charging now because I have a 10:00 a.m. appointment and need to leave the office early today. Here are the usage stats:

• Usage since last full charge 4 hours, 27 minutes
• Standby time since last full charge 21 hours, 58 minutes
• Current call time 57 minutes
• Lifetime call time 7 hours, 27 minutes
• Sent data 482 KB
• Received data 2.5 MB

10:00 a.m. --I plug the 3G iPhone into my Dell monitor's USB port to charge and then head into my meeting.

12:48 p.m.--Charging is all done (yes, I'm sure; I checked and the battery icon contains an icon of a power plug, not lightning bolt ). I reset the usage stats and unplug the iPhone. Oh yeah, I also turn off vibrate. So, now I'm running with no Wi Fi and no Vibrate. I still have Push, Bluetooth, and 3G all turned on 24/7. We'll see how today goes.

3:00 p.m. (appx.) I leave my office for a meeting. Of course, I'm yakking on the iPhone. Good news is that during the 15 minute drive, it did not drop the call. I make a couple of other short calls when I get to my destination 56th St. & Shea). All goes well.

4:07 p.m.--Done with my 3:00 p.m. meeting. Time to make some calls while I drive to the library (Paradise Valley Mall--Cactus & Tatum). I'm on the phone for at least 40 (probably close to 50) minutes--4 different calls in all. Great news: No dropped calls. Slightly bad news: During various parts of the conversations, the person on the other end had trouble hearing me. However, this could be due to me talking on the Bluetooth headset outside (they might have been hearing windnoise, not bad cell service).

7:47 p.m.--My family and I are inside Paradise Valley Mall. I'm in KB Toys. My wife is elsewhere. She tries calling me but I don't hear the phone ring. I don't know whether this was due to me just not hearing the ringer (remember, I have vibrate turned off) or whether the iPhone simply didn't ring. When I realize she has left me a voice mail and I try calling her back, I have trouble getting the call to go through. Eventually (on my 6th attempt), I'm able to speak with her to tell her where I am. That's the last call I make or receive on the iPhone today.

10:20 p.m.--Here are my current stats:

• Usage since last full charge 2 hours, 23 minutes
• Standby since last full charge 9 hours, 32 minutes
• Call time current period 1 hour, 14 minutes
• Lifetime call time 8 hours, 41 minutes
• Sent data 242 KB
• Received 1.5 MB

Battery icon is showing less than 50% remaining charge but more than 30% (say 35-40%?). Once again, it looks to me like I'll be lucky if I get 24 hours on a charge. This is surprising as I've turned off Wi Fi and Vibrate. I need to look at the quantitative data, but I feel as though I'm not getting any longer usage despite my battery saving measures.

While at the mall, I walked passed an AT&T kiosk (this was an AT&T kiosk, not a third party who is licensed to sell AT&T). I told the salesperson about my battery issues. I also mentioned that I've noticed the back of the iPhone gets quite warm when I've been talking on the iPhone for awhile. He didn't think my limited usage or the warmth were normal and suggested I bring the iPhone to Apple and have them look at it. I'll be very close to the store on Monday so I think I might go talk to the folks there and see whether I can't get a different iPhone to try. Of course, I'll have to bring all my figures with me. (Again, I'm not using the internet--although I did use Safari for about 3-4 minutes today; not using iPod function or You Tube.)

I'm still trying to keep track of the number of e-mails I've been receiving. I just don't have that information handy at home so I'll try to post it tomorrow.

Oh, btw, my wife's iPhone has been going for more than 3 days since the last charge and she still has not gotten the 20% battery warning. I'm not going to charge hers until the 20% warning pops up. We'll see if she can surpass 4 days.

Edit (9:20 a.m. on 8/9/0: Between 8:09 a.m. on August 8 and 11:59 p.m. that same day, I received a total of 37 e-mails, substantially less than the day before. Also, in between the time I fully charged at noon on August 7 and the time I had to charge on August 8, I received a total of 42 e-mails, which is probably a more important figure for purposes of my testing. In other words, between charges, I recevied a total of 42 e-mail. During that period, my phone was set to vibrate so it vibrated not only every time I received a phone call but every time it retrieved e-mails using push. In my experienced, it does not always receive e-mails one at a time. In other words, I don't think the iPhone vibrated 42 times yesterday, but it probably did vibrate somewhere in the range of 25-30 times (sometimes the e-mails arrive on the iPhone in groups, especially if the mail server received them within a few minutes of each other).

Jay - you sure your wife isn't plugging in her phone periodically to see how crazy she can make you?

When did you meet my wife and how do you know her so well?

Naw, I'm sure she's not plugging it in. I do like the way the iPhone reports usage time since last full charge--makes it a bit easier to do this testing. However, I really am missing a log of how long each call is.

I've finally had a chance to complete my Day 9 report. The significance is that it is the first day I was counting e-mails to see whether the volume of e-mails I am receiving is causing my battery to be low. Keep in mind that I'm not really sending any e-mails from the iPhone (maybe 1 per day if even that) so if e-mail is my problem, it's due to the volume received. Here's the link to Day 9's report.

Spoiler: I received at least 61 e-mails between 2:50 a.m. on 10:23 p.m. on August 7, 2008.

I've added e-mail information to the Day 10 Report, which can be found here. Spoiler: I received a total of 42 e-mails in between charges, which means my iPhone probably vibrated at least 25-30 times.

I wish I could turn off the vibrate feature just for e-mail notification and leave it on for the telephone ringer notification.

9:31 a.m.--I haven't received the low battery warning yet, but the battery icon looks like it's showing only a 20% (maybe 25% charge). I don't expect a lot of usage the next couple of days because it's the weekend, and I tend not to use my cell phone much on the weekends, but we'll see. Right now, usage stats are as follows:

• Usage since last full charge 3 hours, 0 minutes
• Standby since last full charge 20 hours, 44 minutes
• Current period call time 1 hour, 15 minutes
• Lifetime call time 8 hours, 42 minutes
• Cellular Network Data sent 323 KB
• Cellular Network dats received 1.7MB

In re-reading some of my posts, I'm beginning to think that the critical figure is "Usage" since last full charge. It seems I'm getting between 3 and 4 hours of usage time. I'm not sure my wife's usage time is any different; she might just be able to spread that usage out over a longer period of time. I really need to go back and take a closer look at that usage figure. I'd appreciate it if you all would check your "usage since last full charge" stat and tell me what you're getting in terms of that figure? If you can, check it when you get a 20% and a 10% low battery warning.

BTW, right now I'm getting 4 bars and solid 3G coverage in my office. (Yup, I'm working today. )

10:41 a.m.--Just got the 20% battery remaining warning while look at the AP newsreader app (Mobile News). Stats are as follows:

• Usage since last full charge 3 hours, 14 minutes
• standby since last full charge 22 hours, 3 minutes
• Current period call time 1 hour, 15 minutes
• Lifetime call time 8 hours, 42 minutes
• Data sent 360 KB
• Data received 2.0MB

I'm going to hold off charging for now and see if I can get down to 10%.

A thought just occurred to me. This blog reminds me of when my first child was born. My wife and I kept a log of each and every bodily function. Guess this blog is the high-tech equivalent of that. So, my iPhone really is my "baby."

2:07 p.m.--I'm sitting in front of my computer and received an e-mail, but the iPhone didn't beep to tell me it had received one. Thus, I went to look at the iPhone to see whether I just missed its audible alert. Turns out, it is now showing the 10% battery warning so it's time for me to charge it. I'm not sure exactly when it hit the 10% warning, but I know for sure that it's been within the past 1 hour and 25 minutes or so. Final status this charging period are as follows:

• Usage since last full charge 3 hours, 41 minutes
• Standby time since last full charge 1 day, 1 hour
• Call time current period 1 hour, 15 minutes
• Lifetime call time 8 hours, 42 minutes
• Data sent 424 KB
• Data received 2.1 MB

So, once again, I'm barely able to get 24 hours on one charge and am seeing usage time of 3-4 hours between charges.

FWIW, since the last full charge (12:48 p.m. yesterday), I've received 33 e-mails.

Okay, time to charge....(plugging into Dell monitor's USB port at 2:12 p.m.)

4:48 p.m.--I'm not quite sure how long it takes to fully charge the 3G iPhone, but mine is now fully charged. So, we can safely say that charging takes no more than 2 hours and 41 minutes.

8:44 p.m.--At some point today, my wife's iPhone gave a low battery warning. I'm not sure which one (10% or 20%). Looking at her iPhone right now, I'd say she's got 10% or less left. It's just got a sliver of a red bar in the battery icon so I'm going to charge her iPhone tonight. Here are her stats:

• Usage since last full charge 4 hours, 9 minutes
• Standby since last full charge 4 days, 12 hours
• Call time current period 2 hours, 59 minutes
• Lifetime call time, 2 hours 59 minutes
• Data sent 1.1MB
• Data received 25.6 MB

Because her Call Time Current Period matches her Lifetime Call Time, I'm guessing that I never reset her stats after the last charge. So, the real telling sign is that she's gotten 4 hours and 9 minutes of usage since the last full charge. That's not too much more than what I've been getting. I am beginning to think the difference is that I just use my iPhone a lot more than she does. But I don't think I'm using the iPhone more than I used my i760, and I know the i760 battery was lasting me longer.

Okay, time to reset her stats and charge her iPhone....

8/11/08 EDIT: Total e-mail count for August 9 (Day 11) was 16. E-mail traffic for me on weekends is substantially slower. Of those 16, three of them were PDAPhoneHome.com alerts (subscription notices).

How do you know when it is fully charged? I can ballpark the battery icon, but I don't see any kind of confirmation that it's fully charged.

In the title bar - within the battery icon, if there is a lightning bolt, it is charging. If there is a plug, it is fully charged.

Cool, thanks! I bet this is in the user manual, isn't it?

I wouldn't know. I never read it.

No need to read the manual to find out about that. Just re-read this thread--you'll see that I learned about the different battery icons the hard way.

9:00 a.m. --My wife's iPhone is fully charged so I've unplugged it and reset the usage stats.

6:09 p.m.--My wife's on her way home from the grocery store. She calls to tell me that on her way to the grocery store, her iPhone dropped a call in the neighborhood near our house, but not in the area where I've been having problems. About 5 minutes into our call, reception gets horrible. Then, all the sudden, I can't hear her at all. I keep talking, but after about a minute, the line goes dead. Another dropped call. When I call her back, I find out she's in our neighborhood. I'm thinking of turning off 3G on both our phones to see whether that helps the reception issue. If my wife is not happy with coverage, I'm not happy with coverage, which means we probably won't be keeping the iPhones.

BTW, I touched my iPhone once today--just to see whether I had any voice mail messages (I did not). So, my usage time for today should be something like only 1-2 minutes.

8/11/08 EDIT: Total e-mails received on August 10 (Day 12)=14. Three of those were PDAPhoneHome.com alerts and all but one of the rest were junk. I didn't use my iPhone at all on Day and only turned it on 2-3 times to check to see whether I had an voice mail messages (I did not). Thus, the only activity on the iPhone was the 14 e-mails received.

Jay, I might have missed it. What level of brightness are you using and is your wife using the same?

I keep mine approx 15% auto brightness off.

You haven't missed it; I haven't looked at brightness as a factor. For the most part, I've left both our iPhones on the default settings (but turned Bluetooth on and WiFi off on min).

I just checked and we both are set to Auto Brightness.

You know your i760's battery lasted longer ?! The sammy is rated at 3.5 hours usage time as opposed to the 5 hours of the iPhone. Now there can be a huge discepancy in what the two different ratings call "usage" but I certainly never got anything like the same battery longevity out of a WM device that I get out of the iPhone 3G. I suspect you're using the iPhone a LOT more .. I've had just about every converged device there is and during the first few weeks it would get 10 times the usage it would get after the honeymoon. I'm following this thread but it seems like it's boiling down to battery longevity and coverage. Switch to edge when you're not surfing and you'll pretty much cancel that concern out but I'm having a huge problem with the idea that the i760 gets better battery life - man, downloading email even on strong EVDO was murder ! Edge on the iPhone kills it. *Whew*, I doubt Samsung's mother would agree

I'm just projecting my own personality on to hers - it's what I'd do just to have a little "fun"

I like the usage factors as well. I only periodically used the per call time just to look back and say "dang, that call was THAT long?". I definitely understand your need for individual time counters.

I don't know if you've had the time to check out some business / utility apps in the app store lately, but there is an app I saw (sorry, forgot the name) where you can enter your time throughout the day to keep track of what you spent your time doing. You could use that to quickly enter not only the time you spent on the phone talking with a client, but you could also make notes about the time you spent thinking about other clients during the conversation to bill them as well

I really don't think I'm using the iPhone any more than I used my i760, and I know I could go at least 2 days without charging the i760 because that is frequently what I would do (didn't want to unnecessarily use up charge cycles).

What I might do for giggles and grins is bring both the i760 and the iPhone to a full charge and then see if I can't simultaneously use both at the same time to see how much usage I can get out of each.
