Desire battery consumption

I used my HTC Desire right out of the box without charging it first.
After that I charged it twice when the battery was empty.
I charged it until the light turned green.
Is it a problem that I didn't charge my Desire before the first use?
 
Hi. I don't think so. I did the same.
I used to fully charge first but these days can't
Be bothered :)
 
I performed that "calibration" twice - once after the first, mandatory charge (before turning on the device) and then, the following day.

I can run through a whole day without much problem.

Browsing and telephone calls consume max. power.

However, if at all I play a game - any game - Angry Birds, Fruit Ninja, Wild West... Boy does the battery take a nose dive!!! Understandable, of course...

Satisfied, otherwise.
 
Never had the battery consumption probs some people have. I listen to 2/3 hours of music a day, 20 mins surfing and texting, and get an easy 2 days out of a charge. When I don't really use it, I can get about 4 days out of it (I've turned off all automatic updates, background sync, internet connections and gps)
 
Apologies if this has been touched on, one thing I notice from charging through the night is sometimes I wake up to find the Green light on and battery at 93%, other times the Green light is on and the battery is 100%?! This has been happening since I uninstalled ATK.
It seems that once it reaches 100% charge it then sometimes turns off charging hence the drop to 93%.....is that correct? seems a little odd to me.

No, once the battery is 90% charged, it will turn green untill it finishes charging. At 100% it will stop charging. If you leave your phone in the charger and use it, it shouldn't deplete the battery charge.
 
2 hours after hitting 100% if still charging, it will rapidly deplete to 90% and charge back upto 100%. It will repeat this cycle until disconnected.

ok, so whats the 7% loss all about then? (I'm obviously not using it in my sleep!) thats whats confusing me....must be a reason somewhere.
I also presume by your post it wont re-start charging until it drops to 90%?

Dan seemed to have answered your question.

@ Dan, strange that that'll happen since I've never notice the phone going below 100% when I'm using it and it's plugged.
 
Maybe the charger sucks out some juice before the battery explodes! ;)

Seriously, I think the fast drain after a full charge is either a self protection mechanism, or some power is lost through the earth circuit while connected but not charging, or its the phone doing it's thing and using battery power. Most likely it's some kind of combination of these.

If you're using it, you are using up power, so the charger is not constantly pushing the battery to go beyond 100% (like it would be if it was not being used).

Apparently the desire doesn't support trickle charging so this is designed to relieve stress on the battery.

That said, maybe its not hardware but software limitation because on my AOSP rom, it appears to trickle charge fine so no 10% drop at all.

Its the first. If you plot the battery usage using system panel or something, you will see the power drain is more than if you were watching a movie for the same amount of time. It is very, very rapid.
 
Ok. Battery at 50 % after a day!
So decided not take charger :o
Might all go very wrong later :D

Hmmmmmm.........

A quick Risk/Benefit analysis suggests that I'd rather arrive back home with a healthy battery AND an unused charger! :rolleyes:
 
Hi all. Still going. Battery warning has been on for a couple
Of hours though. Massive improvement on previous. But
In part due to less surfing
 
got up today - phone had been charging for say 5 hrs - so at 100%
spent about 30 mins on web and email and 2 very short calls - battery down to 65% remaining!

I hear ya, my battery performance has been terrible. I am a moderate user: text, 2-5 calls, email, bookmarks, weather, sometimes GPS. Keep my screen on low resolution (mostly 0%). I sometimes use the app killer sometimes don't. I power down the screen and leave it idle doing nothing with it for hours and I will be down to 20%.

I lose 10-25% in the first hour that I turn it on.

I lose 100% when I go to sleep and leave it idle.
 
I lose 100% when I go to sleep and leave it idle.

OK, that should bring up some alarm bells/red lights!!!

I think you have some kind of issues with an app on your phone. Have you check your idle time in the Battery Use info? What's the phone idle percentage? Your phone doesn't seem to be 'asleep' when idle and idle time seems to be the whole night. What are your update times for FB, twitter, news feeds, emails etc? Do you have it constantly on?

Check your battery history by dialing into Testing *#*#46363#*#* on your phone. Go to battery history and select Partial wake usage. See what app is active when you're asleep and your phone should simply have been idle/asleep.

You can do a check with charging it 100% and unplug it before you sleep. In the morning, you should try to find the culprit app.

If you can't find the app from the above experiment, put your phone in 2G and do the exact same thing the next night. How's your battery life? If your battery only went down by 2-5%, then it's a 3rd party app that's causing your battery woe. If you experience the SAME decrease in battery life (100% battery lose when you're alseep), then it's something to do with your phone (stock app maybe) and you might want to do a factory reset.

Hope that helps :)

Cheers,

My battery is similar but it's not due to an app. I live in a building that was built around 1905 and it's made out of brick that has been known to break hammerdrill bits. As a consequence it's difficult to even get one bar of signal without hunting around for it. And just about no signal at all in my bedroom, which is exactly where I want my phone at night, for the alarm function if nothing else. So I end up leaving it on charge all night long.

It won't wear out the radio continually hunting for a signal, but it will wear out the battery.

Oh...now that blows!!!

@ hurtinunit: Do you live in a building? lol
 
Bummer. I would use flight mode at night. I don't want to be called
While sleeping. Or put it on charge while asleep?

What :confused:

It doesn't have to be a choice. You have to charge it at some point so it makes sense to leave it on charge while you are sleeping. It can still be in airplane mode at the same time.
 
I leave it charging but switched on, connected to my WiFi so that I wake up to a new bunch of emails and tweets to read over breakfast. :)
 
Everything's looking good

3G always on, background data always on, auto sync always on.

good times :D
 
Wow, I wish I could get those numbers.

I find that my battery drops 10% every 2-3 hours. My settings are as follows:

3g on
Accelorometer on
Wifi off
Bluetooth Off

Screen set to about 40%?
Mail pulling every 15 minutes
Twitter pulling each hour
Beautiful widgets every 2 hours
Facebook pulling every 8 hours

If it is possible, could anyone give me any tips that might help me improve battery life?

What's the Accelorometer doing? I get at least 30 hours from a full charge and my apps update automatically every 30-60 mins.
