If you are planning on wiping it and starting over ... dont add everything back at once. I dont have sportstap, Pandora or astrid and I get all day out of the battery. from 5am when I get up until 10PM when I go to bed. It is in the yellow by 8pm usually.

 

1. Do you have wifi on
2. If you have wifi on, is it searching, or connected
3. Do you get good or bad service at your house

 

Whoa.. That seems a bit high. I have several email accounts being updated hourly, the weather widget, and seesmic and I'm in the mid-40% range after about 24 hours.

 

Turn 'em off one at a time.

Secondly, when you wake up, look go into menu -> preferences -> about phone -> battery life. What's your awake time like? Sounds to me like SOMETHING isn't letting your phone sleep.

 

Make sure you have your screen timeout set to go off soon. This was a major culprit for me. I got caught up wanting to look at the screens all the time & killed my battery doing so. I have it set to go off in 1 minute, now & last 14 hours with 30% left with light to moderate use...

 

Couple of quick ideas since I went through this myself.

1. Find out what your awake time is. If it's high, you need to find out what program isn't letting your phone sleep.
2. Install SystemPanel. It will give you a good idea of how much each app is running, let you see current usage stats on a lot of info.
3. Remove Flickr if you don't need it and you use Facebook. Took me a complete day of troubleshooting with people here to figure out that was my big problem. Looked like a calendar issue, but turned out to be Flickr.

I'd be more concerned with finding you problem than wiping the phone since there's a chance that it's part of the base OS that's causing your issue. I love SenseUI, but there's no doubt that a few things on here aren't playing nicely out of the box.

 

You either have an app that is a rogue to sleep states of the device, or a faulty battery issue. Last night I had Astro Player on, surfed this site and Bluesnews, checked email and then pressed the power button to put it to sleep (had device on for about an hour). I did not charge it and just now looked and have over 80%. I leave email, sync and data always active.

added:

Widgets can be power hogs. Turn them all off and see how the device does and activate one at a time to see who the offender is.

 

I agree with that assessment. I had the same issue when I installed Good For Enterprise. There is a bug in the app that does not allow the phone to sleep. I lost about 40% of my battery life in a few hours. I uninstalled the app but whatever it did started to cause the same issue with the HTC Facebook App. I ended up doing a wipe and reinstalled apps one by one to make sure my phone was sleeping.

Point is that an app that doesn't integrate with Sense well can crush battery life. If your Up Time and Awake Time are the same then you've got a rogue app that you need to uninstall.

 

1. Install Timeriffic (free)

2. Schedule it to turn your phone into Airplane Mode while you sleep every night.

3. Profit.

 

1. (as a test) turn off the radio for a night. you may think your reception is fine, but it may be searching.

2. check your partial wake usage. anything other than system using a significant amount could point you in the right direction.

 

Do you plug in ur phone while you sleep?

I notice that even with mine plugged in to the wall. After it fully charges, the battery drains. So by the time I wake up, I'm left with ~92% batt after having it plugged in for 6 hours.

 

I read a trick in another thread that seemed to make my battery drain much slower. After your phone is charged, turn it off and charge it until the green indicator light comes on. Usually about 20 minutes. I know it sounds dumb but it made a big difference on mine.

 

It works but it is not practical to shut off your phone for 30 minutes each day.


I just watched a 2 hour movie last night and started at 100% after the movie finished I was at 60% and that's with the Seidio 1750.

 

Yeah. I do agree that its not practical but I figured if it works then might as well share it and if someone decides to use it then great. If not then I wasted a minute or 2 putting it back out there. I usually do it when its not an inconvenience.

 

I have proof positive of this ridiculous issue. Here's a screen shot from SystemPanel I took last week. This was after 8 hours on the charger overnight. I woke up, checked some stuff while still plugged in then turned the phone off, unplugged it and powered it back up. SystemPanels monitor was set to stay on after restarting and you can see that the charge never reaches 100% once on battery. I don't understand the reasoning behind this, but yesterday I decided to test out the "extra charge" technique. I unfortunately didn't take a picture but after the the extra time I did the same restart procedure and the battery was pegged at 100% for a good amount of time. In fact, after 13 hours of light use yesterday I was at around 65%. I then played HomeRun Battle 3D for 90 minutes and still had over 20% left. The thing I don't know is if it's the way the phone charges the battery, or the battery itself that has this strange issue. I'll be picking up a Seidio so I can stop watching the meter.

 

Someone commented that its a design thing because it takes the last 10% so long to charge compared to the other 90%. And they made the phone think it was charged before it was. And that quick drain after unplugging is the result. Idk if this is true, just what I read.

 

It can show you if any apps are preventing the phone from sleeping. There are some other reasons for apps to show up under Partial Wake Usage, but for the most part if anything is showing significant numbers it is worth looking into why. I had a similar situation (phone draining 40% overnight) and tracked down the app causing the issue using this method.

You can see the usage in a number of apps (spare parts, battery left etc.) I am not certain if it can be found without a 3rd party app.

I use Battery Left Battery Left Widget - Android app on AppBrain

awesome widget

 

I'm not using AppKiller or any other task killer.

Seems to me, that app would suck battery too.

 

does this app drain battery while it's doing its monitoring? it's a cool app. it's nice to see it track everything, but i could see all the tracking potentially eating battery by itself.
