Battery draining, dont know why?

[ebor]

I posted this in MightyROM. It might be of some assistance here. Didn't have enough posts to just provide a link.

I've been trying to take an analytical look at the battery consumption issue. Using the acbPowerMeter I posted earlier, I have been adding and removing applications; turning applications on and off and changing settings. For instance I tried turning off and on BT and then I tried turning the discovery off and on in BT. After hours of trying these things my conclusion is except for transmitting, it's that big display that soaks up the power. I loaded psShutXP and used the Display Off soft button that pops up. The power consumption goes down so dramatically that I though it shut everything down. But it doesn't. Power consumption goes under 10ma average. Still receives mail, text and calls. You can see the blips of increased consumption when those events occur and then then goes back down dramatically. Those people having battery issues may want to try psShutXP and see if that helps any. Those of you that are looking at BT issues I would load the power meter and see if the theories your working on are valid. There are probably different issues causing the problems based on what apps are loaded. This is just one obvious one.

What are you guys using to listen to Pandora!?!? I can't get Pandora to even load right on my browser. How are ya'll accomplishing this?

Actually, you might be right about the Windows Live part. I have been getting worse battery only recently. I hadn't noticed it as much because with school out I hadn't been out and about as much. But the same setup did for sure work fine before (push Windows Live and Google Sync). So either it's the new 6.5/VZW Radio or some Windows Live change.

Normally I help people with questions when they should search, but seriously? You don't even need to know what to look for here, just type Pandora into the search...

Windows Live and Google Sync will decimate your battery, especially if you have a poor service. There's some programs which will do it too - SmartLock will. Turn off push e-mail and it should last a lot longer.

On my TP, without push e-mail I'd have maybe 60% battery after a day, with great service all day. With push e-mail enabled, it would be below 10% every time, if not dead. Same goes here, though the TP2 doesn't have as terrible of a battery. I've still been yet to get my TP2 to have the battery life my TP did but I don't have as much stripped out either - weather updates, e-mail every hour, etc and I get through every day just fine.

Right, but what I was saying is that my battery was good before, even with 2 push email accounts on. In the newest MightyROM he said he fixed a bug where Windows Live would hang in the background, so maybe that has something to do with it.

I know I have stripped my GMail Sync out & not use it @ all.
But my Hotmail is my lifeline to the world - so that is turned on as mail arrives.
So when you say Windows Live, are you particularly saying the Mail program on the TP2 that drags in your Hotmail as it arrives (I can only have 1 native Hotmail account in the TP2 mail section).

That would be neat to see if it can be portable as a reg edit for other ROM's including stock.

Do you have specific link to referenced?

[butler360]

No, it's somewhere in the 2,000 page MightyROM thread, haha. And I'm not sure if it was related to his ROM specifically or applied to others as well.

I suddenly noticed a very steep battery consumption when I turned the phone on this morning. I have been installing cabs each day since I got the phone last week, but before this, I have been getting about 2 days out of a charge. I have been running it down to about 5% before an overnight re-charge.

Not sure what caused the sudden steep drop and kicking myself for not noting the nominal mA rate when everything seemed fine. But now I see average discharge rates around 200mA when nothing is running and the screen is on. I changed from "Global" to "CDMA Only", but that did not appear to do anything.

I just installed acbPowerMeter, so I will also do some experiments to see what is affecting consumption and report back.
