I have put up with all the other shortcomings, but now the battery life seems to be seriously failing lately.

I can get up and have a fully charged phone, make a phone call or 2, go to the office and lay the phone down next to me as I do paperwork or see patients. I might answer 3 or 4 calls during the course of the day, no more than 10 or so minutes each. Wifi is off. Bluetooth is off. Screen is set to 50% brightness, and I am very careful to immediately turn off the power button as soon as I answer or make a call.

By 3pm or so I have maybe 20% left on my battery. By the time I'm ready to leave for work my phone is shutting off completely due to no power. I know part of the solution is to carry another power adapter, but I just can't believe I cannot at least expect a full days of use. And thats not even pushing it, it's only maybe half a dozen calls and otherwise it just sits on my desk.

BTW the signal at my work is consistently 2-3 bars, so not sure if reception is the issue. At home I only get 0-1 bars and it seems to last about the same.

My next step is to hard reset and not install any programs and see if something might be leaching battery power. Other than that I have no clue whatsoever!

Forgot to add, push email is OFF. Can't think of anything else sucking up the battery life like this. Sometimes I can just let it sit with the screen off and no phone calls at all, and during the course of the day it will still be almost dead by early afternoon.

That's unusual Doc, try to take it back and get a replacement battery under warranty (or Call customer serv). I know that with Verizon the battery is under warranty for 1 year... not sure about Sprint's policy.

The number of Mogul returns must be staggering.

There isn't anything at all using your data connection? My battery life goes in the toilet when I start using the data connection on a constant basis. Otherwise it's pretty good.

My battery goes all day (7a-~5pm) and I still have 20-30% left - with push email on..

Something's up w/ your device or some of the software that you're running.

Are you charging with the supplied charger or a generic usb charger?

Thanks guys, I guess my next step is to swap it out. Sprint is usually pretty good about it, but a tech has to look at it and I don't know how he will figure it has a bad battery.

I am not using any data as far as I know, but not sure if any program I have maybe is. I will hard reset it first and play with it only with Pauls dialer and my contacts loaded.

I am using the supplied charger/cable. Even when I get up in the morning, one call and I sit down to breakfast and it already is down to 80%.

In the last week, my range is from 17 hours high down to 5 hours yesterday (solid surfing). The data is definitely the killer.

If you are in a 1x zone, your battery life isn't going to be comparable to an EVDO area. Take that in mind.

I'd definitely hard reset before returning the phone (the battery is another issue). There are many apps that can keep the data link open. Weather plugins and RSS feeds just to name a couple off the top of my head. Then there is the possibility of something being in a software loop keeping the Processor at full power constantly.

A hard reset will eliminate all of those possibilities.

Also make sure IR is turned off (on by default for some reason), and do the registry tweak that lets you see and disconnect vision data connections.

Turning off IR beaming as mentioned above will make a significant difference in battery life.

I must have missed that tweak. Anyone have a quick link?

Probably elsewhere as well, but I got it off the PPCGeeks registry tweaks thread:

This helped me alot... much better now.

However, I have still noticed that low signal areas kill my Mogul battery much faster than they killed the battery on my 6700. FWIW

Thanks, Viking, works great

One day last week, I went all day and still had 50% when I went home. Today, my battery went dead before I got home. Obviously there are some other factors that are impacting battery life. It's got to be signal strength, the charger, some data error/problem, or the frickin bluetooth. There's something. I did use bluetooth more today.

It's good to know that I'm not the only one with this problem. Lately I have to have my charger with me all day b/c my battery doesn't even last 4 hrs

Not only are you not the only one, but the PPC 6800 may not be the only phone with this problem. I have a Treo 700WX, but am considering getting a Mogul. Normally, my Treo has more than adequate battery life for my needs. It can usually get through a day of moderate browsing and occasional phone calls with plenty of life to spare by the end of the day. But this week, it has intermittently just blown right through the battery. Not every day, but occasionally. I don't believe the issue is the battery itself as my phone is not that old and batteries dying of old age usually do so slowly. I haven't installed any new software either. I'm wondering if it has something to do with the Sprint network.
