Hi!
I was just wondering what happens if you ignore the 10%-warning from the battery. What will happen to the LEO? Will Windows shut down or the device simply run out of juice?

if similar to my old HP Mobile, it might just run out of juice or shutoff at 1 or 2% charge. My HD2 has never been lower than 3% (and didn't switch off) so far so i really cant tell - i simply don't have the time to wait till its totally empty
It will shut itself off and likely go into a reboot cycle until it is dead completely. Once this has happened you will most likely have to charge the battery with a wall charger to get it to take a charge. The USB one will have no effect at all even though it says its charging. This is what has happened to my TP2 and the Leo should not be any different.
It shuts down properly on 1%
Then if you reboot, it just shuts down again.

This is correct, but, you shouldn't allow this to happen on a regular basis.
at 10 percent you will not be able to use flash of the camera ,all roming options will be closed only main functions will work

Exact. No problem unless you leave it for days without recharging.
Allright, here´s the news:
After the 10% marker I played several rounds Solitaire (and I´ve solved none of them btw... ). 5% marker doesn´t change anything, Edge-connection still working...
3%: Some bug I think. I went to the comm manager and put the phone into flight mode. At this moment the device froze completely. After softreset all normal...
1%: Lasted longer than I thought. No more Solitaire but display constant on (just tapped randomly through the menues). After 5 Minutes finally a high buzzing sound and Slide2Shutdown popped up (it´s a feature of EnergyROM 23544). So I shut down the device and plugged in the wall charger...
So in future I´m a bit calmer when the 10% warning pops up...

What do you mean by "automatic roaming"? Never heard of that.
For me all connections (Wifi, bluetooth, Edge/3G) work until the phone shuts down. There's just the camera flash that stops working at 20%.

there is some options in some programs sya sync while roaming ,this means it syncroize when connecting to internet which uses more battery

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

had this on my tab for 2 days and reflashed back to stock because battery life was awful.
So it happened again. Fully charge the TF for a trip. When I get to my distination (8hrs later) turn on the TF and its dead. No power and no chargers. This thing is pissing me off!
Anyone know why or how I can fix? I do have the wifi off when screen is off.
How is that possible?
Did you not shut down your TF?

It looks like you are having the reboot during deep sleep issue that started with the upgrade to ICS. The reboots can be stuck with the screen enabled and the processor actively trying to complete the boot, which drains your battery.
Short term, I would avoid leaving the TF powered up unattended for long periods.
That will prevent the total battery drain. For a longer term work around, you can try an app called Wake Lock, which you can set to prevent the TF from going into deep sleep, and eliminate the deep sleep reboots, which has helped some users, including me.
The app should be set to restart on Reboot, and select the Partial Lock, then select the Acquire Lock setting, on the red bar, which will switch to green, and indicate that it has acquired. You can also set it to show its icon in the Notification are, so that you have a visual assurance that it is working. Then just exit the app, and it will work in the background.
You can monitor that it is preventing Deep Sleep, using the CPUspy app.
I would then watch carefully to see that you aren't experiencing any more reboots during Deep Sleep.
Long term, ASUS is researching instability with ICS, and we hope to get a true fix. Until then, use of Wake Lock may help you.
Others may have other opinions and explanations, and they may be right, but this has cured my problem for the last 11days. Good luck.

No shut down. I would charge the TF to 100%. turn the screen on to see if its 100% charged and that's it. Then 8hrs or so later when I want to go use the TF, its dead. Can't even turn on.
Can this be the reboot issue or an application that is running and not letting my TF go to deep sleep? Help!

Your response makes no sense. You say TF was shut down then you say TF might not be going into deep sleep. If you power the TF down it will go off and use NO battery. you will get some battery internal discharge but TF will not come on an use battery. Try the same test shutting it off.
Ok...try again. I would charge the TF. Then check by pressing the power button. The screen goes on and shows 100%. Then press the power button to turn the screen off ( not turning it completely off).
When I want to use the TF, it won't turn on, as if its completely dead.
Suggestion?
its either a) you get a RR and get stuck in a bootloop, b) you got some app running that drains the battery, such as Winamp or c) your device is broken (not likely).

Has anybody experienced random shutdowns on their N4? It's happened twice now for me in the last few days. I'll go to turn on the screen and find that the phone is completely shut down and needs powered back up, without me having shut the phone down.
One strange thing associated with this is that it completely wipes my battery stats.
Please provide more information.
Stock? Unlocked? Rooted? Custom rom? Custome kernel? Undervolted?

Are you sure it's actually shutting down?
The reason I ask is that there's an issue where the screen won't wake up, but the phone is still functional (can still hear notifications and feel vibrations etc.). It looks like it's shut down, but it actually isn't.
If so then I believe it's a known issue, even on the stock (unrooted) rom. It happens to me every now and then, and as far as I know it needs a hard reboot to fix (hold down the power button for 10 seconds).
Don't know what you mean by wiping your battery stats? A reboot would do that anyway, wouldn't it?

There's a video on youtube showing how this phone just shuts down after running a benchmark for long enough (that was about 10 minutes at normal room temperature..)
Could it be that your phone was doing something in the background, and because of the overheating issues that it has, it just shut down to prevent damage?

I wasn't doing anything significant right before hand. The last things I did were: checked Facebook, modified a Tasker profile, and swiped away a couple apps from the recent apps screen. Phone was cool to the touch. I was in the basement with no cell coverage (wifi connected), then moved upstairs and next time I tried to turn on the screen the phone was powered off.

No it was shut down, had to hold down the power button for 2 seconds to boot it, felt the boot vibration and saw the boot animation. This happened after being off charger for about 2 hours, but upon booting the battery screen showed on battery for 1 minute. Usually when I reboot the "on battery" time is preserved.

Is there a fix for the screen not waking? I'm still on 4.2(stock and rooted), does 4.2.1 fix it? I can't seem to update to 4.2.1, if it does fix it. But that's another issue...
Ya know I'm starting to think it may be my belt holster that's somehow shutting down the phone. This is the first day of my new holster and now the phone has shut itself down 3 times, each time I've noticed it after pulling it from the holster.

I only had N$ for 3 days.
Yesterday when I was taking a picture, camera app was running, while I was putting kids together phone screen went black. Only way to bring it back was to hold power button and it went through full boot up cycle, so I would say it did shut down on me.
Stock, no root, updated to the 4.2.1. Battery was between 50 and 75% and it did not wipe it's stats.

If you hold just power button it should bring a popup with Power Off option, which is a standard for most Android phones.

I have the same issue recently. I've used nexus 4 for 1 month, this issue just occurred recently. it shutdown without any notice. I've drop my phone once, cracking its glass back, but it doesn't seem to relate to that issue. I guess maybe this is some software problem.
Hey guys, so I'm not sure what's going on but myself and several people on reddit are experiencing this issue:
http://www.reddit.com/r/nexus4/comments/1j7o85/n4_shuts_off_overnight_after_43_update/
Every morning since I've gotten 4.3 update, my nexus 4 shuts itself off throughout the night. It does not boot up until I force a shutdown (volume up and power) AND THEN try to power it on.
My nexus is completely stock, it has not been rooted or even bootloader unlocked. It seems to work fine regardless, but I like to keep my phone on in case of an emergency.
Can someone shed some light on this?

This sounds like the sleep of death issue. User tkolev has written the Safe Charge app to prevent this from happening when the Nexus 4 is charging.

Thanks for the info Bob. However, I don't charge my phone throughout the night, so I don't think it's that.
It's not the battery either because when I do power it up, it's usually at least 40%+ battery. I'm really at a loss as to what could be causing this.

Sleep of death happens when the Nexus 4 is in deep sleep mode and fails to respond to a key press and can occur whether or not the phone is charging at the time. If you are able to charge the phone overnight, I would install and enable Safe Charge to see if it keeps the problem from occurring at night.

That's terrible . It only started when I updated to 4.3, and unfortunately I can't charge overnight. I'm guessing the Safe Charge app drains battery? If so, I don't think that would work.
Is there seriously no other way to solve this issue than a wakelock work around? It seems pretty significant to simply ignore on Google's part.
i hate to say it, but you may have to do a factory reset to determine whether or not its the phone, or some app that you have installed that is not playing nice with the update.
I've found the issue, turns out Netflix's chromecast update screwed up with 4.3:
http://www.reddit.com/r/Android/comments/1jdenw/psa_if_you_have_netflix_read_this_before_updating/
Fix: Uninstall Netflix or stay on 4.2.2 until resolved. Thanks guys.
It keeps shutting off at 3:07 every night?
