Only thing that comes to mind is that wifi sleep policy might keep your phone awake. Other than that, i'm out of ideas =)Yes I have, Partial wake usage is about 16mins (what I'd expect) So screen on and partial wake usage is more like 30mins, nowhere near the 3 hours of running
But just for the record, my phone is a bit moody with sleeping. Sometimes it sleeps nicely for many hours and sometimes it refuses to sleep at all.
Cheers, but I've got wifi off so not sure why the sleep policy would keep it awake? Theres definitely something odd going on, hopefully the next firmware update and/or 1.6 will bring some stability on the battery front.
I was struggling with this battery problem since I got the phone but I think that today I understood the main problem.
When you boot your phone, some system app that's supposed to make your phone sleep should start. (If it doesn't start, you have a problem from the very beginning.)
Then, make sure that you DO NOT kill ALL running apps from Taskiller widget or any such thing, since they don't know whether an app is critical or not.
I realized I was always killing a few apps which I did not have a clue about (such as "reboot" etc.) When I stopped using Taskiller for killing ALL apps after boot, phone started to sleep normally.
at %98 after 5 hours

Thought this as well, over judicious use of taskiller! However, I just uninstalled a weather widget and it seems that was the cause of the problems even though it wasn't showing in taskiller, it was preventing the phone from sleeping. Phone showed 97% after 12 hours (of not being used) which is much better
hi everyone
ive posted before about me not being able to squeez 12hours of the battery but it seems yesterday i found out why. just tried for a change not to keep the phone in the case (pouch) that it came with and gues what after 12hours of work and travellin and sleeping so in total about 24 hours my battery is stil showing 82% with H8 firmware. hey so i gues the case was keeping the phone awake cos it was i think too tight on the buttons. so i gues theres issue then why would pressed buttons keep phone awake even though the screen is off and all tasks killed and apn off.
so maybe someone will make an app for dectivating some buttons from keeping phone active when it should be sleeping.thanx guys

While everyone is holding their breath and waiting for 1.6 and the magical new battery monitor, you can install spare parts to your device. Spare parts will allow you to monitor which applications are actually keeping your phone awake.
Once you install spare parts, head to battery history and select partial wake / since last unplugged. that will show you applications that have been holding wake lock. It'll give you a decent idea on why your phone is being kept from sleeping.
It takes a bit of getting used to, but it has helped me to identify quite a few battery hogs. Latest being swift which had a bug in the 1.0.2 release that prevented the phone from sleeping.
Next step from here is to report the problem to the author of the application that is preventing the phone from sleeping and getting the problem fixed. Don't just uninstall the app and give it a bad rating (and possibly a "it sucks" comment), but instead do the right thing and get it fixed

hi,
thanx for reply, but i forgot to mention that i made assumption about battery from spare parts as i have it installed and had it from day one. so i checked history and says time spent without sleeping in since last boot is about 1day and 13hours out of 60hours since last boot then i have screen on about 8hours and phon for 44minutes and thas all that is showing.
but i can definitely tell that after i stop putting phone into the case (for two days now) i come back home from 12h work and i stil have about 80% o battery left with normal usage.
but i'll try installing the version you suggested and maybe it'll show something else. btw even if any app was rubbish i can never write comments like that coz i know how much work was put into making any of the apps and until i can do better i have to be happy with what they produce,lol.
btw how's everyone elses batteries?what are they showing in spare parts?

hi everyone,
I am %100 sure that the battery issue is caused by the camera button. (case half-presses the camera button and that's why the case seems to be the source of the problem)
Here's my experiment:
POSSIBLE CAUSES (before experiment):
a) cause is not the case.. something else..
b) case touches the screen, screen is too sensitive
c) case presses the overly sensitive camera button
EXPERIMENT:
a) I charged the phone fully last yesterday evening. When I left the phone as it is on the table, phone slept perfectly, battery worked normally. (it was at about %96 after 7 hours)
Then I put the phone in its case and left it on my bedside. When I woke up (after 7 hours) it was at %50 !
Conclusion: Reason IS the case.
b) I thought it was possible for the case to activate touchscreen sensor and keep the phone awake, so I just did this:
* plugged for charging
* put your finger(s) on the screen
* unplug and when screen is awake, press lock button to make it sleep
* wait like 5 secs, then open "Spare Parts" and look at statistics.
Conclusion: the phone slept perfectly (without the case, fingers on the screen) so touchscreen is definitely not the problem.
c) tested this:
* plugged for charging (without case)
* press "camera button" fully
* unplug, press lock button to make it sleep and wait 5 secs
* open "Spare Parts" and observe statistics.
Conclusion: Phone did NOT sleep at all! The problem is definitely the "camera button"!
It doesn't matter if it's fully pressed or half-pressed (tested both).
We need an URGENT firmware update for this!
Does anyone know any developers at Samsung??

thats pretty naff that the camera button at half press keeps it awake
did you try this with any other buttons? volume up and down?
EDIT: just tested your theory, seems it only does that if the camera button is held down before locking
if you unplug the charger, wait till the charge icon goes, lock the phone then hold the camera button down for 10 seconds and go back in to check the battery history on partial wake it shows it was awake for 1 second

what firmware version on the device you using?
if i lock first then press the keys it stays asleep unless its volume or power
so unless i got some frankinstien device that is different to everone elses it could be that theyve fixed it in the firmware im using?

you shouldn't be looking at "partial wake", partial wake shows %10 awake time but "other usage" shows that the phone was awake for %99 of the time..
I'm pretty sure that:
Sleep Time = 100 - Running in "other usage" tab of Spare Parts, since last night that tab showed the sleep "gap" correctly.

Im running H8 Firmware, and can confirm the battery power usage under "other usage" is low when out of the leather case and locked. When in its case it doesnt sleep, screen is off but spare parts states near to 100% usage.
All you have to prove the point is turn your camera on, shove it in the case and watch the camera LED turn on.....
Solution one : Ditch the case and go with something else... a sock lol.
Solution two : Cut a hole in the case where that bloody camera button is!

and i see i was right saying that case keeps phone awake, as many more people report the same and even do small investigations (well done).
so i think this issue of buttons keeping the phone awake should be sorted in the coming firmware version just i dont think samsung is aware of it as many people here didnt believe that case is draining battery,lol. or just some app that would deactivate all button apart of the unlock button when the screen is locked coz we cant do anything with other buttons when its locked apart from when we need to flash firmware.
by the way should i upgrade to II5 from H8 or just wait for donut to come (if ever) and then update. how's the battery with new firmware? does it last any longer? coz mine last more than two days now when not in case with low to normal usage.
thanx

The battery life in H8 is seems to be better but maybe its all physiological now.
Im charging my battery to full and going to see what happens tommorow without the case on. Should be confirmed if i go from one day of battery usage to more than two days......
Note: You can check if its sleeping by touching the running bar and looking at "Total time spent without sleeping"
Upgraded to II5

Sorry to refer to this old post, but to respond: Any old Psion device (Series 3, 5, 5mx, Revo) is able to do that. For the Revo, ChaDis was my favourite. By very accurately documenting the power spent, and given a solid start reading, it's capable of giving a very realistic estimate of remaining life. My brother was able to do a hell of a lot of battery stats, and discover which manufacturers lie least about their mAh figures.
Good times...
But yeah, I guess it's all down to hardware support ... so this may be out of bounds for the current generation of Android devices.

i used this device with no case and its managed to last 2 days
so i take back what i said about the camera button. it must be the main cause as its acting like a normal phone when not in the case
