Maximizing Battery Life?

[kirkwood096]

I'm a Verizon user, and I use Wireless Sync to obtain my corporate e-mail. Wireless Sync is definately a battery killer. I found that with Wireless Sync completely disabled, and while still running WeatherPanel (obtaining updates every 30 minutes) I still have 80% of my battery remaining at the end of the day. While running Wireless Sync, I'm lucky to have 20% left at the end of the day (and that's with making very few calls).

I have been testing this, I also have my work email with an exchange
server!, its awful bad for my battery life, but i found that if i use
XCPUscalar, and bring my cpu down to 208mhz, and only read/send emails,
(no games, not toooooo much calling, and no internet), i can still have about
30% battery after my whole day!

I tried uninstalling wisbar, and ilauncher, and leaving all other programs
i usually have running close,

I didnt see a much of an improvement.

so the basics are, dont use it.
if you think you wont be able to charge it for a while, underclock it and keep to the basics!


on another note,
Is it me, or does it killlllll the battery when you use the touchscreen ?
if check my emails and dont use the touchscreen, i always end up getting like 5% more battery left at the end of the day, but then it might be that
some days i get more calls then others!

ok any program that connects using the internet or phone app will drain the most life out of you battery..second thing is programs running in the background will shorten the life of your battery and yes UNDER AND OVER CLOCKING DRAIN THE BATTERY TO...i found out by underclocking you can use more power dong that than overclocking...by setting your phone to suspend will dramatically reduce the life of your battery with no running programs in the background...

Good post. What's the range on the y-axis of acbPowerMeter signify? I find it changes everytime I open it. Also, what are the Now: and Avg: values?

What do you mean programs running in the background? I have a few like ilauncher and pocketbreeze, but I don't notice more battery drain having them on.

Y axis? Math is hard... is that the one that goes up and down or across

Up/down is current mA draw.
Across is time
So you get a reading of the current mA draw at the sample rate, graphed over time.

Now: is the current draw in mA
Avg: is the average mA over the entire sample set
I believe it also gives you the total mAh for the sample set - ie, if you ran it for an hour and averaged 130mA for the hour, the total hit on your battery is 130mAh... so subtract that off the 1350mAh and see you've used ~10% of the battery.

Stuff running in the background is any app that is running. Today items run, even when the today screen isn't showing - they should only wake up and see that Desktop isn't the top window, then go back to sleep. Other apps, for example tmail (Outlook mail) may be running all the time even if not visible in the "running apps" list, but are visible in a process listing, might be running even when in the background doing stuff (checking email, pulling weather data, rss feeds, who knows ) as long as the device is not on standby (ie, when you hit the power button or it times out and goes to standby on its own) - apps that have requested to be run at a specific time can wake up the machine out of standby... do some work, and then let it time out again.

All that works against your battery life, but the three deadly battery killers remain
* Voice call
* Data use
* Backlight

Along with the forth horseman of the battery apocalypse, WIFI.

there's an option in ppc6700hacks to turn menu and window animations on. Would this use more battery?

I have a quick question concerning battery life and bluetooth...

I know if you have bluetooth enabled and a paired device turned on and in range it will drain your battery... But, what if you have bluetooth on, on the phone, but no paired devices powered on around it, will it still drain the battery (other than the little blue flashing light, lol)

I'm just trying to determine if I really need to turn off bluetooth everytime I'm not using it or if I can just leave it on and turn the headset off, etc..

Thanks.

Yes, it will still drain the battery. Why? because it's looking for devices to pair with, and that takes power. You can tell how much power various configurations consume by using tools such as acbPower.

up and down. X axis is the across one.

a well written today app won't even wake up if a portion of it isn't visible.


I thought this was hysterically funny:

don't use your 6700 to talk to someone

on second thought, don't do anything with your carrier

you know, maybe you shouldn't do anything wirelessly with your wireless device

Yep, that settles it - just don't turn it on at all.

That's not a phone/wireless/ppc/remote/flashlight/mp3 player - it's just a really expensive storage case for a $20 proprietary battery.
