Delete the task killer, you'll find your battery lasts longer without it.

 

And juice defender is good. Bit buggy at the moment, but well worth it, as the developer is quite good at sorting out problems!

 

Switching off the automatic updates for Friendstream (Twitter and Facebook) as well as for the Weather app incl the animations seem to have made the biggest improvent to battery life for me.

 

Yeah, I think we need a thread that is positive about our batterys and how we set up and possible drawbacks/benefits. Not just a pointless moan. Also we could put our current usage with regards to how effective they are.
Right I have the power widget like you, plus the data widget. Plus I turn off data location services as used by the phone and certain apps. And I turn off gps location services.Both of these settings can be found under settings, location.
I turn off background data and auto sync. Again via settings, account and sync.
I turn off always enable mobile data via settings wireless networks, mobile networks,
I have wifi sleep policy set from never to 15 mins, this can be found under wifi, then pudding menu, then advance wifi settings.
Also as ive mentioned before, on boot up (i make sure I reboot my phone assurer every full charge). I go to running services via settings applications. I stop the obex callender, and g talk. I do not use task kilter or any task manager. But i do stop those running services and have noticezero issues. Thee is another calender service that i leave running.it says c connectivity services or something l like that.
Now this set up maybe poo for many of you. Petty much everything is off right? But when i wanna turn on gprs, or refresh my emails or weather, it takes me a click our two. No bug desk for me. not when you check out these figures.

battery uptime (figure only makes sense after rebooting from a full charge).

14 hours, 50 minutes.
Awake time
2 hours, 43 minutes. During this time ive spent an hour and a half browsing the net via gprs. Checking emails twice, about ten mins on calls, a few texts. Listen to songs via headset for the rest.
Battery remaining, 83 percent. That for me is not too bad at all. I do charge every night, But I can go 2 days now with probably 5 or 6 hours uptime over both days.

 

I have "Advanced Task Killer Free" installed have it as one of the selected apps to be 'killed' so it isn't always on. Are you saying that would drain the battery too or am I confused?

 

I installed it and its good. Better now. But im no expert, i just through caution to the wind!

 

Sorry thats a typo, (i know there were many typos in that thread!) I meant to say, I uninstalled task killer! Its good without it, just takes abit of trusting. Im no expert though.

 

I did the data off test, and found it used more battery reconnecting the data for syncs than leaving it on 24/7. On Tmobile, not sure if a network quirk or typical behaviour.

Juice defender used more battery than it saved, so I binned it after 3 days. 3% overnight without rose to 8% battery drain with!

 

Yeah and I agree, there are circumstances/users who would not suit to turn data off. However, I think alot depends how often you sync. Mine is disabled, including any apps trying to suck data. I connect maybe 5 or 6 times a day and sync maybe 2 our 3 times and have noticed good increase in my favor. Also I think it depends how much you move around different locations. Its possible the hunting and changing of signal uses more battery. Also possibly a benefit I get is that I will have less missed calls as if you have updates going on in the background whilst on G, at the time you receive that call, it will go through to answer phone without ringing.

 

On a side note:

I have an office job - 7 to 3.
I keep my battery topped up by charging it when it drops to 70% while at office.
I have a car charger, so I charge it when its below 70%.
I never have low battery in the middle of the day. Towards the end of the day it may be low but I have used 1.5 times the life of the battery per day.

 

when I got my desire I was lucky to get 4hrs without having it put it back on charge.

it was really doing my head in and thought my battery was shagged and bought a brand new one off HTC site.

now I had a brain wave, my email app was constantly connected..so I went into the email settings, it was only connecting every 15 mins... now its set to connect manually. now I can get 7hrs out of my battery with quite a bit of useage.. streaming using the flash player, loads of internet browsing, downloading, music player... all before it needs another charge...

damn you email app
