Hi guys,
I tried out the quickboot feature and turned my phone off at night for about 10 hours until my alarm rang again. In this period the phone drained about 25% battery. If I don't turn the phone off overnight it drains about 3-5%. Did you experience anything different?

I experienced this too, I put the phone into airplane mode and then quickboot and it drained 5% which at that point there is no point in using QuickBoot to be honest if its going to require airplane mode.

I'm curious I recalibrated my battery to last longer I usually lost around 7-10 percent over night. Now after calibration I only lost 3% and this is what my consumtion was and was curious is this normal or good. I'm getting 43% cell standby, 40 phone idle, 15% display and 2% OS. I was going to post a pic but is not letting me right now.

With my stock rom, I usually use about 3% over-night when the phone is shut-off.
So, either the stock batteries suck, or "off" doesn't really mean "off." I'm assuming the latter, since we have to pull the darn battery to get a true reset.
3% overnight sounds reasonable. Same here.

Maybe you have fast boot on. Or it sucks up a lot of juice just turning it on

Sure do (enabled by default). I'll switch it off tonight and see if the percentage changes in the morning.
so is fast boot something we want on or off?
I look at fast boot as hiberateing. Take that off and I believe your phone will actually shut down all the way. Fast boot is fast boot. After shutting it off and turning it back on and starts up quicker. Sounds like something that would suck a little bit of battery life over night.

With fastboot disabled and the phone shut off, you should see 0% to maybe 1% battery drain overnight.

Yeah I think its from powering down and back up that's it.

To recalibrate it I just powered up to 100% powerdown, unplug chord reboot into recovery go to advance and go to wipe battery bin. Reboot amd you should have a more accurate battery %. You should 4.2V at 100%

3% is more than reasonable.
I lose like 1% per ~2 hours standby with active 3G data connection, and gmails pushing emails.
I really dont get this, i killed all running tasks before i went to sleep, fully charged, but when i wokeup the battery is at critical level already. Wifi is turned off. This happened for 2 straight nights now. In the morning the batt drains normally. Help anyone? Whats causing this?

Mine would do that when I left WiFi and WiFi Calling on. Maybe try turning sync off. I know that putting the phone in Airplane mode will save the battery from draining. Might only drop 3-5% overnight.
running the sgh-i727r.
had the phone since boxing day and this was the first time it happened. went to sleep with about 70%, slept for 6 hours and then woke up to a turned off phone. turned it back on and battery showed a huge drop from when it turned itself off, shortly before i woke up.
the only battery saving app i have is juice defender, on balanced profile.
any ideas?
thanks in advance.
Download betterbatterystats from the market and find out what is using your battery...
Are you rooted? if so.. reboot into recovery and erase battery stats and calibrate your battery..
More then likely have an app running..
My phone was reduced from 100 to 82 in just around 6 hours. I had data/wifi turned off as well. Is anyone else experiencing this?

Nope. With data/wifi turned on (data auto-off since Wifi is active), I lose at most 2% overnight. With airplane mode on OR data/wifi off, you should be seeing practically 0% loss.
Check your battery usage and see what's eating up the battery. Sounds like an rogue app/process that's wasting cycles or is out of control.
One of the best things about this phone is its standby life, as it seems to sip battery juice very lightly.
My battery was still 100% after I woke up today.
Nevertheless it dropped very quickly after using the phone, about 11% in 10-15 min but I assume that's completely normal after 8 hours standby.
I have a live wallpaper but it shouldn't work when is screen off. I also have setcpu set so that is practically doing nothing when the screen is off. The live wallpaper cost only 2% of my battery but standby showed 20%. I have no idea why it uses much in standby...

That means that of the whatever % battery (out of 100%) that you've used, 20% of that drain was due to standby. That's not necessarily bad. So if you have 50% charge left, then it means that (50% x .2)% of your drain was from standby. My cell standby has currently used 23% of my current drain percentage. Since your phone is often left in the sleep/not-active state, then a large % of battery drain happens in standby.
Battery usage on Android is frequently misunderstood. And keep in mind that the 2% from the LWP you used is because it's only displayed when you're on the home screen. Otherwise, it remains dormant/paused.
that's strange that you are having that much usage in standby.. i have been getting a solid day and a half out of my battery and it doesnt really use any battery in standby.. there has to be an app of some sort that is sucking the battery or still running.. i always at bedtime though clear the cache thru storage in the settings menu and end all tasks in the task manager and close all the windows/programs with the far right virtual button on the bottom of the screen.. I am a bit OCD but heck if its working why stop..lol
Area with poor cell reception? If you were in plane mode it is an app for sure.

My battery stayed the same overnight. That is with a x2 battery saver which switches off data when the phone is not used and only allows it as special intervals. I have set at 10mins intervals though which is not a huge saver.
I'm doing a test from yesterday to see how long the phone will last with my use. So far from last night im at 39% and when I first turned the phone on it was at 47% from yesterday.

I would have to agree with everyone else. I only experience 1% loss at most times overnight. Best standby battery life i've ever gotten on a HTC phone.
I actually have full bars at home so I don't think that's why. Maybe it's because it's a new battery so I'll try charging it a couple more cycles.
Lost 8% tonight (86/78). Saw this morning that the signal was not perfect. But wifi went off during the night. That should not happen. Maybe my custom rom is switching off wifi on sleep...

It's either a faulty battery or a rogue app. Shouldn't happen to a new battery either.

Use better battery stats to diagnose rogue apps.

Right.
Battery lasted up to 2:30pm being off the plug from 7 am the previous morning. So a total of 31hours.
That is with tapatalk, a bit of web browsing, a bit of WiFi and google store updating, 2 short phone calls.
The app. 2x was running on mild battery saving,mainly by cutting the data periodically when the phone is idling.
I must say that this is really good and the phone took quite a while to go from 15% to 4% after which it switched off before I noticed it again.

Greetings:
I am just wondering if my new note pro battery discharges normally.
The tablet is left at 91% at 10:00 pm yesterday. Nothing is running in the background, Power saver is on, screen brightness about 25%, only wifi is on, multi windows is off, all sounds setting off, haptic feedback off, push notification is off, it is down to 76% this morning at 6:00 am. Without using it for 8 hours, it loses 15% charge. The battery usage shows that the screen uses 47%, android system 14%, and android OS 11%. I ask the amazon online community and some users report that their tablet loses only 9% charge without using it for two weeks. Is my unit defective?
Thanks in advance for your time and help.
You've got an app causing a wakelock. Reboot. Put it in Airplane mode tonight to see if results are better. I lose maybe 1 or 2% overnight when I use airplane mode.
Mine drains at 0,2%/h according to BBS. So no, yours is probably not discharging normally.
If you're rooted try Wakelock detector. If you're not, try BetterBatteryStats. Both can be found here on XDA
Thank you all for your help.
After turning off many running app which i didn't launch, set auto brightness to on, the tablet seems to hold the charge now.
