I told them about the calendar (like in the templete email in the previous posts) but they never mention calendar in their reply ??

I too was having propblems with the calendar, it was killing my life. It was using 70% of my battery which is rediculous. So I removed the calendar widget for a little while, rebooted and it fixed the problem. The calendar is not even showing up in the battery use section.

Not saying its a perminant fix, but it worked for me.
[Desire General] deksiberu:
hello there.. i'm kinda newbie here.. :)

sorry if i post in the old thread.. i bought a Desire and now i'm having a same problem, the battery is drained very fast :(

when i open battery information, it says that the display takes 64% - 80%

the calender is fine and so others do so...

i also find that the back of my phone is very hot!

now, the battery just last about 1 hour after i unplug the charger.. :(

anybody can suggest a way to fix my problem?

i'm using gingerbread ROM 2.3.3 and it's rooted.

thanks in advance
[Desire General] petzlux:
Okay some more information.

The widget doesnt seem to be the cause, but the calendar app itself.

Tried rebooting after having removed the widget, after reboot, still the phone didn't go to sleep and calendar was responsible for 70-90% partial use...

Next thing, I killed the calendar, after that, HTC Sense restarted. Left it alone for 15 minutes and when I checked the phone had gone to sleep (up time > awake time)

Rebooted phone again, left for 15 minutes and calendar exposed previous behaviour (uptime = awake time). Killed calendar app again, 15 minutes later uptime > awake time.
[Desire General] choccy31:
I use pure calendar Grid app and don't have this issue. Live wallpapers (darker ones at least) do not affect my battery much, if at all I've noticed.
[Desire General] gens6200:
I'm getting the same results as you: Doesn't really matter what I change in terms of widgets, syncing etc. I even did a factory reset. But after killing Calendar with Astro and ObexService (calendar) and ConnectivityService (calendar) in "Applications>Running Services" I'm also getting up time > awake time. Unfortunately I'm pretty dependent on the calendar, so not really a viable option.

I'm guessing you're on a T-mobile rom? I'm on 1.15.405.4 Generic (nordic). My calendar version is 7. (in "Applications>Manage applications")
[Desire General] swordvish:
I have the same issue i.e. Uptime = Awake time

After killing ObexService only, it seems to goto sleep. So far ObexService hasnt respawned

[Desire General] petzlux:
Well the point seems to be that after killing the calendar, I can go back and use the widget and calendar, and it will still go to sleep after that. There seems to be a bug with the calendar that starts at boot time that means its in a state where it prevents sleep. The restarted calendar doesnt seem to exhibit that behaviour!
[Desire General] madmossy:
Not sure what I did with mine, but after replacing the battery yesterday im getting much better battery life.

Yesterday by this time i would be on 25-30% battery from 100% at 8am.

Today im on 68% from only 84% this morning.

Under battery info my up time is 1h 21m my awake time is only 0h 23m. Previously it was 1/1 pretty much.
[Desire General] gens6200:
I think that the variables are:

Calendar (app)

ConnectivityService (sync service)

ObexService (???)

Calendar widgets

I'm currently trying out all different combinations, but untill now ObexService seems to be the culprit. However for me it doesn't seem to work if ObexService is killed independently - Calendar also has to be killed and then started up again. But if i do that the phone actually goes to sleep.
[Desire General] EroThraX:
No issue my end, exactly the same processes running and the partial awake usages are tiny.
[Desire General] swordvish:
Network device or sim free purchase?
[Desire General] gens6200:
Thank you for replying.

Would you mind checking what firmware version you're using at the moment?
[Desire General] gens6200:
Update: ObexService is NOT the culprit after all. I rebooted the phone, killed calendar via "Manage applications" and then started calendar again without doing anything else (and with 2 calendar widgets in use) - This did the trick. The phone is now going to sleep - as Petzlux found out.

Re: Potential cause for excessive battery usage

Cool. At least it looks like we have a partial solution - will be interesting to see what this will do for battery life.

[Desire General] jonneymendoza:
NICE ONE THANKS.

anyways i am trying to stop connectivtyService under calender and it seems to always restart itself :(
[Desire General] gens6200:
You have to switch off Google calendar sync in accounts and sync. Then you can kill the service - but your calendar won't sync of course.
[Desire General] jonneymendoza:
I've tried that and still no joy. i went into accounts and sync then onto google. i then unchecked Sync Calender which was already unchecked from when i tried it before and the last time it got synced was on monday.

i do have background data and auto sync enabled from the main accounts and sync activity
[Desire General] gens6200:
Strange.. I removed all calendar widgets and unchecked Google calendar sync in "accounts & sync". Then I force closed the Calendar app in "Manage applications" (alternatively in Astro). The last step was to end ConnectivityService and ObexService in "Running applications". That did the trick.

But killing and restarting the calendar app was the main thing for me - Something in the app is causing the phone not to sleep, but after restarting the app the phone sleeps.
[Desire General] tuntang:
dont PUSH me!

Anyone out their an orange htc desire person that needs PUSH synch all day because there phone is their main business phone?

for me, i need calender synching, as with email and contacts and PUSH seems to be the only way forward. surely using a black background on a phone like this is equivelant to driving a ferrari down the street at 30mph. whats the point?

at phone threatening to crash out of charge after one day of push use, with 20mins talk time is pants.

so- anyway, i drained my battery last night in the hope that this will change things. i'm also waiting for the ROOT to occur as i'd like to blame this all on orange.
[Desire General] gens6200:
Update: This morning I noticed that the phone wasn't sleeping (again). I haven't rebooted since killing and restarting the calendar app yesterday.

I killed and restarted the calendar again, and sleep is working again - So it seems that we should do the calendar kill+restart more or less daily untill HTC comes up with a fix.
[Desire General] gens6200:
Just a thought: Are you using push exchange as well as auto-sync gmail (+gcal & contacts?) That'll drain any phone very very rapidly.

I'm using exchange and gmail, but with exchange at an interval (not push) - My work e-mail doesn't really need to be updated while I'm sitting in front of my computer at work - And going out to meetings etc. I generally open the mail app or widget in the taxi and then it updates.

Look into the calendar issue, since it could drain your battery faster as well. If you don't have the symptoms (awake time etc.) then fiddle with your settings and maybe have services that you don't need not syncing constantly (could be Friendfeed, News Reader, Stocks etc.) Also put the Power control on a home screen and toggle things like wi-fi and bluetooth. GPS is less of an issue, since it only draws battery when it's actually needed - at least in my experience from the Hero.

On a side note: Is anyone else getting jealous reactions from their significant others, because of too much time spent with this beauty? I for one am totally floored by the phone! It simply flies when I compare it to other devices (my old Hero (gsm), iPod Touch 2g, iPhone 3GS). Just loading websites is so much faster and the actual usability factor gained from this (combined with the gorgeous large screen) is actually incredible. The build quality is excellent and droolworthy with the combination of glass screen, aluminium and rubbery plastic. Hopefully HTC will be on the ball with updates this time around. But I just don't see any alternatives to them at the moment - This phone is hot!
[Desire General] gens6200:
Could something have gone wrong when the rom was flashed at the factory?

Would it be worth doing a reflash? Any good advice for how to do it?
[Desire General] TurkzZ:
after a few restarts and tweaks my battery is working great, i set up an exchange active sync, this does email calender etc, and i turned off the separate google sync and the stocks sync, uninstalled sky app and now 14 hours in, played a few games, few short calls and google talk convos and its only used up 2 bars of life :D

i also get the 3g and wifi on off buttons on the home screen , so when i sleep or on tube i turn em off
[Desire General] jonneymendoza:
The calender app is closes via Manage applications but the service for it remains open at all times.

ObexService i can stop but the ConnectivityService restarts itself imediatly after i stop it via Running applications.

i have also removed the calander widget from my home screen and only have the people widget, facebook, latitude, music player, sms and friends stream.

I have turned off mobile internet and wifi as well

Re: Partially solved: Potential cause for excessive battery usage

does anyone have any idea why the Android System uses so much battery?

I had a G1 with Android 2.1 on it and Android system barely figured.

is it because of HTC sense?

Why not try replacing Sense with HelixLauncher and see?

Re: Partially solved: Potential cause for excessive battery usage

found my issue. had to stop the stock app
[Desire General] petzlux:
Has anyone reported the behaviour as a possible bug to HTC? Does anyone what the process is to do this?
[Desire General] swordvish:
ummm has anyone read the thread? :rolleyes:
[Desire General] Rexton270:
Typed the code (btw thanx for it) and got similar values as madmossy.
[Desire General] choccy31:
lol

Re the battery charging to 90% only or 100% and dropping fast, HTC has said there is an issue with the battery reporting software which will be fixed in future update. Battery is fine they say, it's a software glitch.
[Desire General] Eggcake:
Mh...don't know if this was normal, but today battery went down from 100% to 95% in about 5 hours of low usage. Then i started the browser and surfed 5 webpages (actually just 1 but clicked on about 5 links) - took about 3 Minutes. After that, battery was at 89% ?! I know that surfing uses a lot of battery, but 6% in 3 Minutes???

Something is a bit strange...in general, battery usage is quite okay for me when I don't use the phone that much. But as soon as I start the browser or even TapaTalk battery drops so incredibly fast it's unbelievable. The same happened with tapatalk. I only got 3 forums in Favorites. I looked up the first 10 Threads (just the overview) of the 3 forums and opened maybe 3 of them and replied to exactly 1 with a short post. Also took about 5 minutes.

Same story: battery dropped about 7%!?! :eek:

Edit: Both over 3G
[Desire General] mrdo:
i have to say that the battery life issue is a complete mystery to me. it's never been great but tonight it dropped 40% in about 4 hours with my phone in standby the whole time apart from a single calendar reminder. sigh.
[Desire General] jonneymendoza:
edit: stupid thing came back on, on its own :mad:
[Desire General] gens6200:
Letting our friends at HTC know about this...

Haha.. Well actually it's kind of a good point - If we all e-mail or call HTC customer service, then they surely can't ignore the issue - assuming that it's not our handsets that are actually faulty in some way.

I've already sent them an e-mail about it through the form on their website earlier, when we didn't know about the calendar-kill trick. So I sent them a new one after that little discovery - Haven't gotten a reply yet though.

Here's the e-mail - please do copy as much as possible, if it can make it easier for you all:
[Desire General] gleepface:
At 6pm last night my phone was fully charged. Went to see my boyfriend, hardly used the phone, sent two texts and showed him some features for all of about three minutes. Woke up this morning and battery was at 52%, which is clearly ridiculous. checked battery history and yep, said it had been running 100% since last unplugged and calendar was responsible for all partially awake usage. This is so frustrating.
[Desire General] gens6200:
Hmm yes. The calendar app also went back to preventing the phone from sleeping on it's own.

Why do you wan't to kill the ConnectivityService btw? If it's not in use it'll just sleep and not use battery or cpu or anything - A little RAM at most..
[Desire General] petzlux:
Re: Partially solved: Potential cause for excessive battery usage

I have submitted a bug report as well. thanks for the template ! if I don't hear from them in a weeks time might give them a ring . anyone here have experience with HTC telephone support ? any good ?

Today again a bit shocking...I got up at 09:45. Battery was still at 100% (was on Airplane Mode over night). I enabled 2G, updated Mail, Facebook and weather. BAM 98%. Okay. 1 hour, 1 photograph, 1 call, 4 SMS and 1 MMS later (no internet used) : 93%...wow, now that's fast.

Edit: And ofc it's sleeping correctly.
[Desire General] gens6200:
I called them once and it seemed ok really. The guy really took his time taking down the correct info, but couldn't do much besides passing it on to their devs. And it was an english guy who spoke perfect danish, which was impressive by itself!
[Desire General] swordvish:
I just tried an alternative approach & called T-mobile UK & they've agreed to do a full replacement. It's coming tomorrow, so I'll report back whether I have the same issue with the new handset
[Desire General] mcgon1979:
I use the calender widget (is that the same as the app?). I have no battery issues. I'm on day 3 of moderate use now and still with 20% battery remaining.
[Desire General] gens6200:
Just an update: After doing the kill + restart of the calendar, my Desire is now only using about 1% battery per hour with my normal medium-light usage.

Still might try to get a replacement unit though. It shouldn't be like this, and the fact that it affects some people on very different roms worry me a bit - Anyone thinks that this can be solved in software?
[Desire General] gleepface:
Hmm, so after charging my phone, took the charger out, and went to manage applications > calendar

There was no force stop option, so I guess it shouldn't cause me problems?
[Desire General] gens6200:
That should mean that the calendar app isn't running - check your awake time leaving the phone untouched for 20 mins or so.

Also, you could use the battery console (*#*#4636#*#*) to see battery history. If it's running 100% since last unplugged, it's a problem - otherwise, you're good!
[Desire General] kinkade:
ok so i ran my phone down to zero last night and fully charged it,

its now been up for 4.45 hours and has used 10% of the battery with 26mins awake.

so it seems that that is now done, my only concern now is that it has used 10% and i have not used it at all this morning except to check power and the usual syncing that it does with my google a/c.

what does anyone else think of this?
[Desire General] gens6200:
It seems a bit higher than what I have today, but nothing that can't be explained by different usage patterns. And 10% in ~5 hrs would give you a total battery life of 45-50 hrs! I think we should be happy that the phone will make it through the whole day and have 30-40% left at night. Most 3GS users I know need a mid-afternoon top-off, and they consider that gold standard!

I'm beginning to think that the battery stats are a bit off btw - I can have it running 4 hours where it eats 4%. And then it can take another 5% in 20 minutes. There's been a few people mentioning this in other threads as well.
[Desire General] kinkade:
yeah, it's obviously not terrible but i really havent used my desire at all, it's just been sitting there on the table.
[Desire General] jonneymendoza:
Thats whats making the calander usage appear so large and also prevents my device from sleeping.

i turned it off last nigth before going to bed and check ti this morning and it diddnt launch itself anymore. my device as of morning at 7am was around 95% and as of now? 80% and i have been on the phone for manybe 30mins in total this morning as well as pulling some new emails, twitter/facebook and RSS feeds on the way to work using 3g/wifi. i have disabled 3g and wifi and only enable it when i need to pull some data from the net.

80 overal is not that and i checked my usage and the wifi is the most used one which is correct and calander is used only a tiny tiny bit.

if i diddnt use my phone at all since charging it, i think my battery would definetly be on the high 80's/low 90's.
[Desire General] gens6200:
That would be cool - Since a lot of people don't seem to have the problem. Maybe you could compare your firmware versions as well in 'about phone'?
[Desire General] Quist:
I've been monitoring my battery usage and trying all kinds of different things to get more life out of it.

I don't have the problem with the calendar keeping the phone awake, but did have issues with foreground apps like Nimbuzz and SipAgent. After turning them off and using the phone minimally (just with push Exchange email and a little surfing), I managed to get 20-30 hours out of it, depending on how much I surfed.

In my investigations, I found that using only 3G no wifi lets the phone go into the resting state to a greater extent (down to about 6%), but draws more battery keeping the 3G connection live. With wifi on, the phone has to stay awake about 30% of the time, but lasts maybe 15-20% longer than on solely 3G.

Still, as soon as I started using the phone like you should be able to use the phone, it would drop down to about 12 hours again.

Looking into it, I noted a GTalk process that was always on (I don't use GTalk). Killing the process in settings, it looks like I'll get phenomenal battery life. So far, I've been using the phone about 6 hours with regular use and still have about 85% charge left. Theoretically, this should allow about 40 hours of regular use, but realistically, I hope to get about 24. At about 25% charge, things seem to take a dive.
[Desire General] gens6200:
I noticed the Gtalk service as well. I set gtalk not to log in automatically, so it's a bit strange, that it's running by default. But since it's not keeping the phone awake, it shouldn't make much difference. But would be cool to hear more about your experience.
[Desire General] gleepface:
Took a while for the calendar app to show so I could kill it, by which time about 20% of the battery had drained. Anybody else had this? I would assume it just wasn't running in that time though so maybe my battery is just throwing a fit today.
[Desire General] jonneymendoza:
Update. 51% now. been geting emails and syncing friendstream for about 20mins on the way home. did the same once i got a clear signal again and been reading emails and **** while i diddnt have signal underground.

not bad. 50%
[Desire General] Eggcake:
I noticed with the app "CPU Usage" that the Service "HTC Check In Service" is at 10-20% CPU Usage. What is it, why is it so high, how can I reduce/deactivate it?

I'm at 60% now, last time I charged it was 20 hours ago. So that's pretty good for me. 2G + Data was on all the time (WiFi if possible), push mail active, some sms, some phone calls, some surfing, some gaming. Med usage for me.

Still, that service bothers me a bit. Could it be push mail?!
