[Q] Battery problem, stand-by

Hi all. Here's the thing. Yesterday i've charge my galaxy (up to about 90%) set up alarm for morning, and going to sleep. In morning my battery was empty, i don't have idea why, because i push power button to "sand-by" on my phone in that night. What's the deal? Stand-up time was about 7h - is there any fix for that, or maybe it's some kind of bug? Oh that was my first stand-by mode for so long time (phone is pretty brand new, about 3 days from purchase)
Few words about phone:
-i9000XXJF5
-no root, flash, and any modyfication
-in phone i have about 20 instaled apps, 4 widgets on
-no task killer
-about 3 days from purchase phone
-home screen set on LauncherPro
Any advise guys?
Sorry for my english.

There must be some app draining your battery. My SGS usually drops only 4% in battery percentage during the night (I turn of 3g at night using SwitchPro, and I'm on JM2).

Have you installed the latest Facebook for Android app? It drains battery a lot because it keeps the phone awake 100% of the time. Uninstall it, or at least Log out from within the app, so that your phone can sleep in idle mode.

Yes... the problems of Android... I use CPUMonitorMini to keep an eye if any apps go rogue and start hitting my CPU 100% and draining my battery dry.

No i don't have this app. Maybe the problem was autosynch option ON.

[Q] A500 shutting off overnight while charging!!

I just discovered this "feature" this morning as well. -_-

Did u find how to fix this?

I love the feature where the A500's battery doesn't last overnight with the screen off. I didn't think I needed to charge it overnight since the battery was at 95% anyways, so I just set it on the table next to my bed and went to sleep. Woke up this morning and it wouldn't power on. Pretty cool. Wonder what is draining the battery? My DroidX can sit on the same table for almost a week w/o being charged.

I haven't seen it, then again I play music from getting into bed till I wake up so ill try leaving it to sleep and see what happens.

Me too
Same issue here.

i have not tried the trick that I just found that seems to extend the batery life....I put the tablet in "airplane mode" , enable the WiFi and the battery looks like it is draining alot slower. There is power being used for "cell standby" even though is a wifi only tablet

Same problem here with shutdown on charge. Right now it seems fairly consistent-

I'm experiencing them same thing when leaving asleep for extended periods. It first happened while I was charging... now it happened again when I left for dinner and came back. I don't see any setting options for that

Same here. Thought it was a "feature" to keep from using as much battery.

So shutting off notifications seems to stop the problem for me.. except that I don't get notifications At least it boots pretty fast

Lets run some tests, shall we?

I don't think they're shutting off, I think they're crashing/freezing during sleep and not rebooting.
This is speculation by me, and could be different for different people.
Finding the problem:
The test.
Night/Bedtime
This is an overnight/while you sleep test and requires about 2hrs. of your time beforehand. Record your figures if you can and post them for debunking. A couple hours before bed and while you use the tablet during the evening, charge it. After 100% and once it's off the charger please don't use it for anything. We want to simulate the sleep process for about 90m before bed. So if you use the tablet even for a quick web surf, plug it in and getting back to 100%. We're going to allow ~3% for errors anyway but we want to be as close to accurate as possible.
90m before you're ready for bed remove the charger. Don't use the tablet simply set the brightness to auto and take note of your battery level and the time. 60m in take a look at that battery charge again and record the time and charge level. 90m in is the last check and after this whether you go to bed or not please don't wake the tablet. Don't worry if it seems to wake and go back on it's own. That's inconsequential for this test. Just put it somewhere that no one will bother it and resist using it until you wake up. Please
Morning/Wake time
Wake it up.
1. Comes on? Record the charge level and time for posterity so we get an idea of idle drain here on the thread. Everyone gets different values. You'll have to run this test at another time as your shutdown/freeze hasn't been reproduced this time.
2. Doesn't come on? Try a power on press. Comes on? Same as 1. Record the charge level and time and post it here.
3. Doesn't come on? Try a power on press. Doesn't come on? Plug it in and power it on. Now do the same as 2. Record the charge level and time and post it here.
I hypothesize a few different scenarios the summary of which is that I don't think they're shutting down, but this is mostly based on the assumption that the batteries are being charged while the unit is frozen. If they do not charge then my entire test would have to be re-designed. I surmise they freeze and don't restart so they either run out of juice or they're actually frozen when you try to power them on and the long press is rebooting the unit, not powering it on. If I am right then we should see that the batteries are drained as if they have been on all night. This is going to be very imprecise, but my idea is that we'll take the charge % of your bedtime check which is a 60m mark check and just times that by the amt. of hours you were sleeping.
So if you were at 95% when you touched the tablet for the last time, this would mean a drain of ~5% give or take ~1% due to your use while checking, per hour. You take that and multiply it by how many hours you've slept and you'd get X x 5 = 40% which leaves the tablet with ~60% battery when you wake up, again give or take 3% for errors, syncing during the night etc.
If you're seeing a somewhat accurate numerical representation of this formula then it means the tab drained all night.
If you're seeing something way off like the tablet still having way more than it should then it means at some point in the night it really did shut down on its own.
People who are actually saying it shut off probably just reboot the tablet without realizing it as it was on the charger when it froze. Since a power off/reboot press of the power button is roughly the same length as a power on press, it's difficult to differentiate sometimes.
Solving the problem:
I have had this happen twice and it was while I left GPS on.
I haven't had an android cell phone yet that hasn't frozen or reboot itself when I left GPS on for extended periods (aka overnight) so the first time this happened I instantly knew to check and I purposely left it on the second time to reproduce and the second time, the tablet ended up rebooting not freezing. If you're not technical the easiest way to know if your tablet reboot during the night is to leave a web page or IM window on the screen or leave music playing.
You may want to skip the above "finding the problem" tests and attempt this "solving the problem" test. As I mentioned, this is all speculation so I'm just trying to get to the bottom of it and I'm sure we can as a grp.
Once you rule out hardware though, then it's a problem. So if it is indeed NOT the GPS then we're at the mercy of Acer and Google because otherwise there'd be just too many factors to track down.

I'm getting this and i'm loosing a ton of battery somewhere in the process too. I think the above poster is right.
I plug in tabby. go to bed. wake up to pee. see tabby is 100% battery. unplug and go back to bed. wake up to go to work and tabby is powered off completely and battery is anywhere between 85%-90% in a matter of 2-3 hours after being unplugged.

Its likely a rogue app I would get a program like advanced task killer watch it and see what apps are loading in background after you kill all apps.look for apps you installed.not so much the ones Acer put on your tab.
With Ti backup freeze the first one you think should not run give it a day.if that's not the issue keep going down the list.
Had a similar issue it was a app I got from amazon.that was So CALLED FREE.they are not so I uninstalled everything from amazon. No more battery drain.
SOME APPS do not fallow the drained android or social rules
Watching the apps to be sure nothing is running CPU cycles allow the time I loose about 2 to 3 % batter life over night with wifi set to stay awake.
This is ideally from 11 pm until around 10 am the fallowing day.
Yes I sleep in alot giggles

re-flashed with Taboonay v.2.0/Richardtrips v.3.3 Kernel and it fixed everything.

had this on my tab for 2 days and reflashed back to stock because battery life was awful.

[Q] How to conserve battery charge

My battery seems to drain very quickly, even when I keep it on stand by. Doesn't seem like going more then 4 hours if not doing much. Is it normal? Any tricks, tips, or apps to conserve the battery charge?

If it is really that short with the screen going to sleep I would see what apps you have installed. It sounds like one of them is going rouge.

turn all auto syncs off....i usually get about 40 about 3 days worth with moderate use

i usually keep it on Airport mode when I put it to sleep. Should I also turn the auto synch off?

Watchdog Lite App can tell you what processes are running "hot" in the background.
Where's My Droid Power App can tell you what apps are using the majority of your power.
Juice Defender App can automatically disable your WiFi connection for you so you don't have to remember to disable it. (There is a free version. I'm not sure if that one will be good enough or if you will have to buy the full version. It is one of the very few Apps I've bought because I liked how well it worked on my phones.)
I get days of standby with my TF. (As in 3 days mostly standby and had 38% battery left.)

[Q] Weird battery behavior, high power consumption on sleep mode.

I noticed something suddenly different with my A500's battery. I have Battery Monitor Widget installed and I track the battery drain. Previously when the tablet is on sleep mode it consumes between 3-7mA; which I think is normal. But now for some reason when the tablet is on sleep mode the power consumption doesn't immediately drop to the minimum. It decreases slowly. it took an hour to decrease from 200mA to 100mA then another 3 hours from 100mA to 20mA. All during sleep mode. Long sleep is no problem. I lost about 7% over 8 hours of sleep mode. But if I use it for a minute with 1 hour intervals it never goes down 150mA. I loose 3% power every hour over a minute of use. I've gone as far as factory resetting the tablet but it's still the same.

I had the same problem. Turned out to be a leaky widget. Couldn't tell you which one, since I installed quite a few and then got rid of the en-mass.
Do you have anything non-sotck, other than the battery widget installed? Might want to look at those first.

I have factory reset the tablet and my only installed widget is the battery monitor widget. Maybe that's what's causing the leak. I wonder if there's any alternative to that app that can do the same thing.

[Q] sleep mode on watch?

I want to spend some time developing a 'sleep mode' for android wear. I often sleep with it on and would like a mode which keeps the light off while I'm asleep.
Has there been any effort in implementing this, and how would you proceed?

Bump to that!

thats a nice idea

Great idea. I'd suggest activating sleep mode either when the watch is placed in the charger, or give users the ability to set start and stop times for sleep mode.

I agree, thats cool. It would be great if the smartwatch 3 could stand in low energy mode without light all the time. Because the smartwatch 3 has a transflective display. You could read the time with display-light off.

The closest I've seen is the sleep as android app. I've tried with mixed results but I never seem to get the watch lighting up while sleeping

There seems to be a sleep mode on the next update wear 5.0...you can get the screen on by Double tapping screen or by pressing the crown button

Bump!
Would really love this, an app that unchecks the ”Always-on screen” setting for selected hours of the day, so that the watch automatically turns screen of when you sleep for example…

Oh please..... We need this
I hate manually turning off the watch before bed and back on in the morning. But I did get 36 hours with 9% battery left on my LG G Watch using this method

Someone should write an app that can auto toggle the new theater mode at night/quiet hours
I usually turn the watch in airplane mode in the night... Burns 1% per hr battery overnight on my moto 360
