The battery on this phone is ridiculous. I'm coming from a 700p to this phone which is giving nothing but battery problems and weird bugs. First of all 6 days ago I changed my 700p to the 6800. I left the battery in the phone and put it in my laptop bag so that I could use it as a PDA in case something didn't transfer to my 6800. Yesterday after not being able to stand all the problems with the 6800 I reached into my laptop bag and guess what the Palm was still on with only 13% of the battery gone. My 6800 will eat 13% of it's battery in an hour and half with only bluetooth and the phone on this is asinine.

For everyone saying turn off bluetooth that's just stupid, I turn off the little switch and wi-fi still stays on. I then go into Comm Manger and turn it off and it turns off. But it must still be on because there is no reason with just the phone on and bluetooth that this phone can go dead from when I take it off the charger at 7:30 and at about 4:00pm with me only being on the phone for less than 10 minutes and answering 3 text messages. The rest of the time it sits in the holster with the keypad locked and the screen off.

Am I the only one who finds this nuts!?

wifi switch is a hardware switch, if you turn off the physical toggle switch and wifi still stay on, you got a defective unit

with the 6700 BT at idle use very little battery, I imagine that will be the same with the Mogul

my phone is fine it sits most of the day in my truck well im working and i get in and it is at either 80% or 90% depends on how many emails come in. i love the battery in 6800 so much better then stock 6700 one. maybe you are switching between 1x and evdo alot.

Here's something that may or may not do anything (but it was a suggestion from back during my Treo 650 days):

Plug your phone into a wall outlet (using the supplied cable). Once your phone is plugged in and charging (do not have it connected to your PC during this time), do a soft reset. Leave the phone plugged in the entire time, and turn off the PPC once you get back to the main screen. Leave the phone off until you see the green 'I'm done charging' light pop on (and if you charge it more than that, don't worry about it).

What this may or may not do is reset the battery's 'maximum charge' level. I frankly don't know if it'll work here, but it helped a lot of people in the past.

The common answers though (bad battery or you're constantly in a very poor reception area) seem to be right in my mind.

When I went to work this morning, I forgot to take my bluetooth headset. I usually have bluetooth on all the time, because I use my headset frequently throughout the day. I turned off bluetooth since I didn't have my headset and noticed my battery power has stayed at 80% all day and even late this evening!!!

With bluetooth on, the battery would drain in approx. 6 hours. I have to charge it every night and sometimes charge it again in the afternoon. This makes me wonder if it is worth using a headset so I can keep better battery power. I'm spoiled using the headset though, and I don't like holding the phone to my ear during calls.

I guarantee you the BT is not the root problem.

I do not even own a BT device and BT is disabled 100% of the time.

Yet some days my battery drains in a few hours and others it takes 9-10 hours, under practically the same circumstances each time.

Back in the days with my Treo 650, there was a noticeable (but not severe) battery loss if I had the IR enabled (as the Palm could occasionally poll the IR receiver to see if something is being beamed over) along with Bluetooth on. As such, I always had them turned off, and I always had some insane battery life (2-3 days with light usage of both the phone and 'net were easily possible).

While Bluetooth shouldn't be a huge drain, could there be some issue with the Bluetooth stack in the Mogul that's causing the problem?

I have another suggestion for those who have battery problems - try turning on Flight Mode (turns everything off) overnight or something and see what battery drain you see (obviously charge it before you try this out). If you see any more than a 10% loss (and odds are you'll register no power loss at all), you have a bad battery.

the new rom "seems" to eat battery faster than the original rom even if the phone is just idling

Today my battery dropped down to 20% after about 9 hours hardly doing anything on my phone at all.

All it did was sit on my desk at work and occasionally I'd check my emails from Windows Live & exchange server.

I'm starting to wonder if Windows Live is draining the crap out of my battery if set to "As Items Arrive".

80% battery use when not even connected to IM or making phone calls is nuts.

Once I turned off the IR, I got better battery life. Start -> Settings -> Connections Tab -> Beam
