Battery Life

Sensor usage is probably the sensor that detects light and automatically adjusts your screen's brightness level. It might also be the camera, considering when I open sensor usage, Google Goggles is what is listed under there. That, coupled with your gallery constantly being open. Hmm.

Seems like a software issue, once again.
 
I think you have a bum battery. The LCD and OMAP chip on the DROID are much more power thirsty than the AMOLED and SNAP chip are, and yesterday, I was at 70% charge after 17+ hours. In the last hour before bed, I hit it unnecessarily hard just to chew up 10% of battery so I felt comfortable putting it on the charger again (don't want to get stuck with a dead battery on the road!) I'm about 7 hours out and still at 90+%. There's an app on the Market called Quick Settings. It's the only app I know of that allows me to set my screen at absolute 0%. I don't know if it works for the N1, but you can try it if you want to see if reducing the screen brightness further will help. Other than that, I would appeal to HTC to send you another battery.
 
I would bet the sensor for the gallery is the Accelerometer waiting for you to tilt the pictures to move the gallery. I bet this is what is killing your battery. Could not be it, but it could be too. Because of the interface of Cooliris with the Gallery, when you tilt it detects it, and if it is recording the tilt the entire time, that could burn your battery. Just a thought.

I would kill the gallery and then plug the phone back in for few minutes, then unplug it, then let it run so that spare parts can recalc what is using your battery. Check sensor usage again.

Worth a shot...
 
But I'm hardly in the gallery, let alone using it... and it's not even a running process.... at least not something I'm seeing...
 
It doesn't really matter... the phone is going back... i'm not going to waste my time diagnosing a phone that's obviously ****ed up... i just hope the replacement works as it should...
 
You don't have to be in the gallery if the process is running in the background. When I first installed Home++ it had the option to detect orientation switches so I chose to allow that. Guess what...My battery was dying because it was waiting for me to switch to landscape mode.

Your gallery is doing the same thing. If it is open and running in the background, then it is waiting for an orientation switch, and thus using the sensor to do that.

Send the phone back. There might be something really wrong with it. But I would be curious about what would happen if you killed the gallery with a task killer and ran the phone another day... Just saying
 
Well that's something I can look at with replacement... Packing up the phone tonight to ship out in the morning... Regardless... it sounds like it would be a flaw if the sensor stays on all the time....
 
It's my only huge nag... everything else was great! It's gonna suck to be without a Nexus for the next 4-5 days... :( ;)
 
Took my phone off charge at 630am yesterday and it's at 50% at the moment. It's not dumb phone good, but I can live with it. I've been showing it off too so I recon I could get a bit more out with lighter usage.

I do need to find a way for the alarm to work though.

6h 48m ........ 31% :(

phone literally just sitting there since last report... just checked a couple emails... that's it


battery use screen says:

Voice calls - 60% (this is literally only 50min of calling - ONE call total actually, which was to HTC customer support) (time on 51m 35s)
Display - 22% (on 39m 58s)
Cell standby - 8% (time without signal 2%)
Phone idle - 4%
Android System - 3%
Email - 2%

(that's it - nothing else listed, nothing else used...)

It's the voice calling, it kills the battery on this device.
 
If anything, I think my battery life is improving.

I am more careful about installing data-intensive apps from the Market. For example, I use the default weather app as it is the most accurate and doesn't use the battery as others do. Personal view of course.

Mine is now lasting 15 hours or so.

no it's not, because i've getting pretty much the same battery drain pattern even with having made NO calls, or just a 2 min call.... sure if you spend a few hours on voice calls, but this is not the case...

mine was getting worse... despite all the tricks... all the battery conditioning...

phone is packed up and gone now... just having to agonisingly wait for the replacement to show... :(

They couldn't just replace the battery parts only? Sounds a bit weak to me.

believe it or not, they said "we don't have any replacement batteries to send out yet"...

and frankly, whether that's true or not, it doesn't matter much, since if it turns out to be bad circuitry in the phone or what not, no new battery will help anyways... i'd rather just get it taken care of in one shot...
 
Had mine for a month now. I get a full day+ of battery with light use, ending in 40% - 50% charge after 16 - 17 hours. 20 texts. 20 mins phone calls. 1 hour GPS. A few photos. Read and write 20 emails. An hour browsing and checking out the Market.

I do NOT leave GPS on. I have 3G connection all of the time. I do NOT use the WiFi. Brightness is on "auto".

A good friend has one. He uses it about 5 times more than I do, has a hundred apps on his phone (actually locked up once by filling RAM) and has to recharge a LOT during the day.
 
I had some questionable battery performance today- was @100% at 5am, didn't use it all and by 10am I had lost 40%. I did notice that GPS was left on, so maybe that was it.
 
well im currently at 25hrs with 47% battery left(medium usage). Even though android does a good job of killing programs when memory is needed, alot of shit still runs in the background. Since i got Advanced Task Killer, it basically doubled my battery.

In fact i didnt believe in it because how good the OS handled tasks. Now, everytime i finish doing anything on my phone i check ATK just to see whats running.

The problem imo for peoples short span between charges is because they have alot of apps(NOT services) running in the background. While these apps are running they still use resources. ex Gallery, Java Midlet(sp?). Try an app killing program and you should see an increase in battery life.

and yes gps drains alot of power.
 
In my lab at school I get some but close to no signal at all. While the phone was in my pocket the back got a bit hot because it was struggling to find cell signal. In about an hour I lost about 15-20% battery life.
 
I just noticed that after i got the update my battery life is doing so good.... I dont know if the update has something to do with it...and i noticed that the phone itself is charging faster than usual, yesterday i charged my phone for like 2 hours when it only had 19% battery and it was fully charged.. thought it was unusual..... Food for thought
 
Well after having to do a factory reset due to an errant app causing issues (like Locale, but not that particular app - think it was something like Timerific) plus, installing a widget to make it easier to switch to 2G when out of 3G reception areas (or when not needing internet access), my battery life has considerably improved.

After 21hours, battery life is at 52%!

Much improved.....I used to be down to <20% by this stage before, or already on the charger
 
Advanced task killer Free (create exclusions for original phone apps others must be killed)
Apndroid (disable 3g with apn droid everytime you don't use it)
built in widget for enableing stuff (disable everything but sync when not in use)

that gives me 2 days easly with 3g and call usage
