Airave is actually a device, not a program. You would need to talk to Sprint about it.

I did have the GPS locator on, though I did not use GPS today. And I turned off the Airave first thing this morning to see what effect signal strength would have on discharge.

The more that I read of other users experiences, the more it becomes clear that many variables are in play. I see 10% per hour discharge with Bluetooth on. A user on SU said that he saw no noticeable difference when he turned off Bluetooth.

My phone does not get hot, while many others appear to have a significant overheating problem. I turned off my Airave this morning, expecting that it was the reason why the device does not get hot and I also expected that a weaker signal (3 bars) would increase the discharge. There has been no noticeable increase in discharge caused by a weaker signal. And during the calls, the device did not get hot at all. If fact, I just picked it up and it is stone cold. Go figure.

I am ready to conclude that build quality varies from phone to phone. According to the NuePower software, my device draws between 75Ma to 85Ma when idle, whether connected to the Airave or not. As soon as Bluetooth is turned on, the draw goes up to between 160Ma and 211Ma at idle. I have seen others report much higher rates of discharge. It could be differences in the software that is running on different devices, but I am leaning towards hardware build differences or perhaps differences in battery quality or the quality of the battery connection.

I suppose that the only way to isolate the differences among devices is to have many identical devices side by side - same software, same signal, etc. Only Sprint or HTC can do that.

If I were seeing the poor battery life that you describe, I think I would make a single call and see how long it lasts before the battery goes dead. If it cannot go 4.5 hours as HTC and Sprint claim, I would take it back again and again until I get one that does. I have not had to try that, but based upon my battery experiences thus far, I think I would get 4.5 hours.

i have similar results. phone off the charger at 8am, push email active as items arrive from 9am-5pm another account every 4 hours and the push goes to every 4 hours too after 5pm. its now 10pm, so 14 hours off that charger with a 45 min call and still have 40% left. id say thats pretty good battery life IMO. i cant understand how some people like us are having decent battery life and others report 10% drain every 15 or 30 min thats far from normal draw. maybe people are having unrealistic expectations of the battery. Its similar to the Touch's life. if you have a 4.2 hour talktime battery (from sprint.com) then every hour on the phone you lose 25% or every 12 min call you lose 5% by the math. Same goes for browsing, average 5% every 12 min. so yes if you browse the web for 30 min and a 30 min phone call in a day youve blown 25% of you battery right there, stanby and checking email takes battery life too. so 50% left after that usage and 8 hours in standby will leave you with maybe 50%. using gps will eat battery, wifi will even more. it all adds up and i dont think people realize this fact.

i see a ton of people saying well i want to have push email and web search and use bluetooth and gps and still make calls and my battery last a full day- its simply not going to happen its the nature of the device. Its not different than any other PPC with a similar sized battery like the original Touch. The treos, mogul, and 6700 all had bigger batteries so of course they last a little longer, its an unfair conparison.

Perhaps we are two of the fortunate who received phones that are operating as designed. At first I thought that it was, as you say, unrealistic expectations. But I have read so many reports from users whose device seems to be performing below specs, that I am beginning to believe that there must be differences in the hardware performance of some of these phones.

As I said above, I think that the ultimate test is to see how long a single phone call lasts. If it does not go 4+ hours before the battery dies (good signal strength assumed), then there is something wrong with the hardware. This test would eliminate the subjectivity and guesswork of closing a program here and tweaking the registry there. Since our phones appear to be capable of meeting the specs specified by HTC, so should everyone's phone.

It is 10:30 pm and my phone shows 69% battery remaining. As I said in a post 3 hours ago, I started at 6:40 am with 100%. There is no reason why others should not expect similar performance.

At 9:30pm last night my phone shut off. I was doing some browsing, picture mail/texting at the local pub.

So 14 hours of what I consider, a pretty mild day of use and the battery is completely dead.

If I had 69% at 10:30pm I'd be ecstatic!

I think I'm just gonna except it as is. I'll probably get a second or third battery and just swap them in and out throughout the day. Now I need to find a Diamond battery and charger and I'll be set.

i went to the sprint store and told them about my problems, they said they'de give me a 2nd battery for free for the inconvenience but since the phone wont be out in stores till mid october i should contact support and have them send me one

[rainfreak]

I'll bet $5 that when you call support that tell you hell no...

I agree with you 100%! That is excellent battery life. I got up this morning and removed the phone from the charger at 6:22am. Went to work listened to an audio book on the drive in (20 minutes local not streamed book) arrived at work around 8:00am. Battery was at 90%. I did a hard reset. I setup activesync to get my contacts back and set it to sync every 1 hour. I turned off weather and beaming. Surfed the web at lunch for 15 minutes. Had 53 minutes of phone calls. Installed Nuetools to see the battery in 1% increments. 13 text messages. So no push email all day and other than the 53 minutes of talk not much else.

So after less than 10 hours at 4:16pm I have 19% battery left.

Currently Running at:
voltage 3.698 V
Discharge 175 mA
Charge 0 mA
Temp 30 C

Do you want to trade phones?

If I run push email throughout the day my battery would be severely worse. I have had the phone for 2 weeks now and the battery is not improving. It may be getting worse.

If I had 40% left over after 14 hours that would be an awesome improvement, especially if I was able to use push email for 8 hours like you.

Do I have a hardware problem is the question? It seems like it.

battery life was a big concern for me when i was originally thinking of getting the diamond but thankfully i have had great battery life much better than my 6700. I can go about 1.5 to 2.5 days with minimal use of the phone. That being about 30-40 minutes of talk time a day 5-10 minutes of internet and about 30-50 texts a day. My last charge lasted me 3 days but i only had about an hour talk time total no internet emails being checked every hour and about 100 texts total. I also dont have an airrave and average about 2-3 bars in my area

WTF? How is that possible. If my phone just sat there doing nothing I wouldn't make it through the day.

There's gotta be something with maybe the Cell Towers in my area.. or some setting I use that you don't. Grrr!
