Hi,
I fully charged my phone (xv6800) during the night, unplugged it in the morning but forgot to take it with me. When I unplugged it I saw that the charge was at 100%. When I returned home nine hours later, the charge was at 70%. I've already performed the battery hacks (http://forum.ppcgeeks.com/showthread.php?t=10507) by going into the registry and doing a reset. I also have the device set to "turn off if not used for" 2 minutes.
I'm a little surprised that the 30% of the battery would be consumed just sitting there.
Does an active but idle data connection consume power? (By this I mean "connected" but not actively sending or receiving data.) I do have the HTC plug-in and that checks the weather every hour i think. Also I've got my mail client set to check every hour. So those programs will establish a data connection but I've noticed once the connection is made it is never dropped - and I'm wondering if the idle data connection is consuming more power than not being connected.
Is there a way to have the data connection disconnect after being idle for a certain amount of time?

I know the battery in the Treo is not exceptional but does this sound right?
Charged 100%
Push Email on
Talked for 45m
BT on
IR Off
No UMTS Hack Installed (had it installed and hard reset device)
13 hrs later dead battery
If this is right it should come standard with two batteries or a car charger. My TyTn never had this problem.
Yep, same problem here, it´s the BT en Pushmail that drains the battery :-((
At first I had horrible problems, but it turns out it was Windows Live trying to sync, and failing each time. Once I disabled that, battery life was back to normal. Obviously things like Bluetooth, UMTS/HSDPA will drain the battery faster.
Same here... Battery lasts for 2 days at most... And I often switch off the phone at night. BTW is not possible to turn the treo completely off (not just the phone)?
Push Email ON
BT OFF
UMTS OFF
Standard talking time
My Battery also lasts 2 days, some times shorter. With push email on, gsm networking.
Some tips that may help you to get some more hours out of the battery:
- lower the screen brightness
- let the backlight turn off faster (for example 30sec)
- Set peak times for your push email, for example turn off push email at night. ( you can do this via activsync-> Shedule
- If you have a umts sim card, but you only use gsm/gprs set the network band selection to gsm only (default is auto).
750v Battery Life
I also barely make it through the day with the Treo 750v.
Band set to GSM
Push = Yes
3 Pop email accounts pulling every 60 minutes
Bluetooth = Yes
I am awaiting the Seidio Extended Battery that is rumored to fit in the same size as the current OEM battery.

Hey guys, don't know if you are aware, but Palm is running a Valentine's Day promotion on the 750 batteries. Not sure if I want to go that route or get the extended battery thru Seido, which doubles the capacity but adds bulk.

Does your treo automatically turn off the GPRS/3G connection after checking e-mails every hour? I cant seem to figure out why the connection stays on and never shuts down unless you do it manually.
Yes, I've also noticed that the 750 does not disconnect from my data connection (T-Mo EDGE) after I close the app that is requesting data. I usually disconnect it manually. Does anyone know if leaving this data connection active, even while not pulling data, will decrease the battery life?
Thanks!

Yes it does, you will barely get 24 hours battery life. Im still looking for a solution to automatically dissconect data after checking emails
I'm looking for any utilities that would help extend the battery life of my Polaris - obviously aware that use of Wifi, 3G, etc. hits battery life.
I've got my device set to bring down emails every hour (useful during office hours), but I don't want this happening all through the night - and don't want to have to turn phone off completely. Anyone know of a util
/way to control the messaging/email polling schedule ?
What really helps is closing the data connection after email check or surfing. This is what costs battery. I've managed with a registry edit that the connection will be closed after 2 minutes of idle. This does a lot for my battery life. First i had 1 till 2 days with a battery, now it runs for 4 days or so.
Cheers, yep via the KaiserTweak util I've already got it dropping the data connection after 2 mins, but I'm still looking for other ways of improving battery life a bit further.

I have a quite opposite problem in TC. I don't want data connection to get disconnected after some idle time. I am not that much concerned abt battery life. Is there any registry edit that needs to be done so that, data connection never gets disconnected untill i want to disconnect it.
Does being connected to 3G eat up that much battery even if the connection is idle?
I was wondering if people turn their internet connection off on their Fuze when they get done using it or do you just leave it connected 24/7.
i do because i use it to fetch my email. having it on already makes it nice to just open a browser and go too. i dont always set up email after a rom flash and it will disconnect data after about 2 hours without use.

I found that leaving data connected when the HSDPA signal is very poor would cause my battery to almost fully discharge in around 6 hours!
However, when configured to automatically disconnect after a few minutes of inactivity it gives around 2 full days of use on a single charge.
Yes its on all the time. I use push email. I turn of 3G most of the time to get better battery life.
Hi all,
I also posted this in the Onyx thread.
Not sure if anybody's experienced the same problem, but I am running Onyx Jr 4.1.4 on my ELFin, and had absolutely no problem with the battery life. I didn't use Outlook at all to check email, because I didn't have a data plan, and just did some light web browsing with Opera Mini. My battery could easily last through a 10 hours day and I would have over 50% battery life left even with moderate use.
Recently I got a data plan, and setup Outlook to poll email every 30 min, and that's when I started getting serious battery issues. My battery cannot make it through a work day, and after ~ 6-7 hours I'd get a low battery warning with 15% battery left. I cannot make it home without charging my battery, or turning my phone off towards the end of the day.
I was surprised by how much additional power email polling drains, even when it's as infrequent as every 30 min, so I installed acbPower Meter, and ran some tests on it. My finding is ...
Phone off, BT off, EDGE off ~ 120 mA
Phone on, BT off, EDGE off ~ 132 mA
Phone on, BT on, EDGE off ~ 132 mA
So I think that's pretty expectable numbers. It shows turning GSM on only drains a bit more power, and BT on/off makes almost no effect. I'm not really using any BT service at this point, obviously.
Now, as soon as I turn EDGE on I see a whole different story ...
Phone on, BT on, EDGE on ~ 326-360 mA
Phone on, BT on, EDGE on, Outlook polling ~ 450-550 mA
So as soon as the data channel is on, even before any data is being transmitted or received (I also use spb wireless monitor to check throughout rate), the drain shoots up from ~ 130 to over 300. And when data is being received, it goes up to 450-550mA!
Fine, even then, an Outlook update only takes ~ 3 min. I setup a program (PhoneAlarm) to disconnect my data channel within 5 min of inactivity, and I thought that should fix the problem.
But it didn't.
So doing a bit more homework, I find what happens is PA DOES turn EDGE off within ~ 5 min of inactivity, but somehow the battery drain stays high (above 300mA) even though EDGE is already off.
I double-checked on SPB Wireless Monitor to make sure EDGE is off, and no data is being transmitted or received. However, battery drain remains above 300mA.
Worse, over time, the 300mA battery drain heats up the battery, to ~ 34-36C, which kills the battery even more. All this without any actual wireless data being transmitted or received.
It seems like the ROM continues to drain the battery even after the data channel is disconnected ... has anybody experienced similar issue?
I ran similar test with WLAN and same result - with WLAN connected, and data received, battery drain goes up to over 400mA. But even after I turn off Wifi the battery drain stays high.
I am not sure if it's a ROM issue, an Outlook issue, or if it is caused by some application on my phone? Has anybody else seen this issue?
You have noticed a very significant difference between Blackberry device and WM, that's why WM is never good at it, no matter comparing the data amount flow as well as the battery usage, it is just not up to the expectation.
The AS is a battery killer, ever since the WM 6.0 and I do not see there is any improvement over the WM6.5 either, hence a even less hope for the WM7, by then, the Android and Symbian will have something to knock it off anyway.
Well, is AS really the problem here though? I have ASynckiller installed and it closes AS when the USB port is not connected.
Not to mention, AS has always been in the picture even before I started using Outlook to check email regularly, and battery usage was perfectly fine, so not sure about that theory.
If Outlook is the problem, I could switch to another email application (say, Flexmail) ... I just don't know if Outlook is the problem here. If Outlook is constantly polling in the background, despite I've set it to update only every 30 min, I should see a higher CPU / memory usage by Outlook, but that's not the case. CPU usage is well below 10% most of the times when it's idling, and memory usage is minimal too, yet the phone continues to drain 350+ mA. It seems like more of a ROM thing to me than anything else.
I have almost the same story as number16's.
I m using onyx, too. though its WM6.5 and that's generally very much of a battery eater.
I just upgraded to stock GB 2.3.5. Everything seems fine (I did a Factory Reset to kill the Tethering Manager error and haven't seen it since).
I re-installed GPS Test app from the market, which I had before.
I've used it a few times. Every time, I end up exiting out and exiting the program thru Task Manager. So right now it is NOT running and doesn't show up in the list of running Apps.
Yet according to my Battery Usage screen, both Wifi and GPS Test are among the top users of battery, EACH at 24% of usage (don't pay too much attention to the high % as this is over the past 2 hrs where only 3% of total battery has been used, as the phone has been sitting on my desk resting). The thing that is weird is that they stay in Lock-Step with each other all the time (ie both always report the same usage percentage). I have Wifi set to "NEVER SLEEP" because I have read that this is actually better for battery life, although here in my office it is not hooked up to wifi. So I understand that Wifi might use battery if it's searching. But WHY does GPS Test use any battery if the program isn't even running? And it does this REGARDLESS of whether I actually shut off the GPS or turn it on in the settings.
Any ideas? I'm about to just uninstall GPS Test but wondering why this might be happening, as I'd like to have the app on my phone in general.
