I unplugged my phone this morning at 7:30 and it is now 12:00 and my low battery meter just come on. I havnt even been using the internet or anything, my email updates every 30 minutes and i keep bluetooth on but other than that i have just been playing with the settings and what not. I have probably talked on it a total of 10 minutes today. I know the battery life is bad but it doesnt seem like it should be this bad. Any ideas?
Talk time 3.5 hrs, stand by doing nothing supposedly 200 hrs.
Data transmission every 30 min is about equal to making a 1 min phone call every 30min, plus when actively using the device you have the backlight on, plus the extra power needed by the CPU being active = lots of power use.
If you had the screen on the whole time I can believe it ran down that fast.
i just cant believe it would drain that fast without really doing anything. Its amazing how much longer the 8125 (wizard) lasted with heavy use compared to this. Is there a slim battery out there that will give me improved performance over stock, i dont know if i want to go with the extended yet...

Hi,
I can certainly understand your objection about going to an extra-large battery. The upside is, that you will nearly double the power life of your phone no matter what you are doing on it. We offer a 2400 (definitely bigger), but we also have a 1500mAh that is standard sized - no different cover is necessary. Granted, it won't give you the same kind of time extension that the larger one will, but if form factor is an issue, then you might want to look in to it.

Ty
Let's assume that you have done all the usual things to preserve battery power: backlight timeout to 30 seconds, battery back light level as low as tolerable, beam receive off, CPU shutdown on battery after 1", etc. Having the CPU up and running as well as the back light on for that period will definitely wipe your battery.
Most of us have gone to either larger batteries or run from charger to charger if we're heavy users.
Good Luck,

I'm not sure about Sprint's ROM versions, but since I updated my VZW VX6700 ROM version I occasionally feel the unit getting hot and the battery dying after just a few hours. It seems to be exacerbated with the new "lock" applet (password protection for the device). But I haven't yet been able to reproduce it reliably. My battery life is much worse since the ROM update in general.
One office i work in on a regular basis is in an EVDO coverage area, but I am burried deep in the building where I barely have signal. When I am in this office my phone will completely drain in an 6 hours with no useage. The phone constantly searching for signal and switching between 1 bar EVDO to 1 bar 1xRTT all day kills it. This is true for most phones ... they use more power when they are searching for signal.
However went on vacation recently in an area that only had strong 1xRTT signal. I was AMAZED how much better the battery performed. I could actually go 2+ days without charging the phone and using it.
So the moral of the story is ... battery life has a good deal of dependance on your signal strength.
I am experimenting with switching the phone to 1xRTT ONLY when I am in that office with little signal to see if that will get me through the day.
I am also having battery problems after the ROM update. I have been sitting here reading this and a couple of related threads for about an hour and the battery has gone from comming off the charger at 100% to 90%. No back light on except to check settings mentioned to reduce power consumption.
Any of you with sudden battery loss using the "lock" application in the new ROM? I've isolated that application to be the only cause of my battery drain.
Not the "device lock" on the today screen, but the password application.
Similar battery issues here also. For the first two months with the phone, I had no problem with battery life. I've done all the battery saving techniques decribed above and that seem to work fine. However, the last two days my battery had been at 10% by lunch instead of being at 50% still at the end of the day.
I've added nothing to the phone in terms of programs since the first couple of weeks I got the phone. I'm beginning to wonder if the phone may be searching for singal more for some reason all of a sudden. My office is the same so I'm just not sure what has changed. Very odd.
I'm thinking of getting a charger for the office. I assume they can be had for a good price at Ebay, but if anyone else has any suggestions, I'd be interested in hearing them. Again, it seems like in the last two days, my battery life has become non-existent.
I'd recommend recalibrating the battery. Lithium Ion batteries should be completely drained, and then fully charged overnight (8 hours) at least every 6 months, more often if you notice significant capacity loss. I did this a couple months ago and my battery problems are a distant memory (for now).
Lithium-ion batteries do not have "memory" issues...and do not require "recalibration"....
Thats a problem with Nickel-metal batteries.....
I have heard of doing this to reset the meter... but not the battery.
On that note...sometimes phones will report a "dead" battery way before the battery is dead. If your device doesnt shut-down...your normally ok.
You can drain the battery if you want....but it isnt a recommended practice...and your only hurting the actual cells in the battery.
I don't recall stating that Li-Ion batteries suffer from memory effect. However, as you said, the meter can become decalibrated and indicate less remaining power than is actually available. Besides being an annoyance, this actually *can* reduce the useful life of your PPC, because Windows Mobile will automatically shut off at about 10% indicated charge. So while the juice is still there, your PPC is sitting dark.

Good point - and one that I've brought to several users attention. Another thing that shortens battery life and is very often overlooked is the frequency of charging. Every battery has a finite amout of charges that will allow it to come up to an optimal level. The main advantage of an extended battery is that you don't have to charge as often, thereby increasing battery life while increasing up time. It is something the folks should think about when looking at overall battery life.
Just a few days ago something strange started happening with my 6700... it is eating batteries. I have two standard batteries and one seidio slim 1500. Yesterday I went through all of them fully charged. From 7am to 11am yesterday one battery was completely drained .. similar rates on the other batteries.
I've installed no new software, made no changes, and I have no software periodically updates itself.
I do use Direct Push with 4SmartPhone.
Last night before bed I turned off the phone's radio and the battery was still at 80% when I got up. Since turning on the radio again I am down to 40% within an hour.
I saw the other thread on power, so I plan to install the abc power meter, but does this sound like a hardware failure?
Is there any change that could have been made on 4SmartPhone's side that could be causing this drain?
At home in the central NJ area I have great signal, I always have full EVDO signal.
That's why I was wondering if something 4SmartPhone changed could create this situation. They had a long outtage recently and I just thought they might be tweaking things on their side (complete guess on my part).
Nothing has changed on my end ... apps, signal, environment ...
Could be - I switched from 4smartphone because of that outage and the constant struggle of my desktop outlook to connect to their servers. Try setting your activesync on the phone to poll every 30 minutes manually rather than on demand, and see if that changes. Or, if you can tolerate it, turn off direct push entirely for a couple of hours and see if that makes any difference.
Be careful of using ScaryBear's software on devices that have been upgraded to AKU 3.3 or greater. Clearing some notifications can cause your device to fail connecting to ActiveSync. This has been mentioned in the Colonel's 3.3 upgrade thread.
That application wasn't really designed for WM5 and according to the author of the software, WM5 doesn't have a problem. I guess he doesn't own a WM5 device. I would recommend using MemMaid to clear excess notifications without harming the ability to use ActiveSync.
