So I was wondering, if I'm not going to use the table for a whole day (or a little bit more) is it better to shut it down completely or just leave it on stand by? and, is it safe to treat the tablet as a cell phone, I mean charging it everyday before I go to sleep?
Thanks!
ps: I tried searching but I couldn't come up with anything helpful, I would appreciate a link tho....
I rarely ever turn off my TF. I always keep it on and let it go to sleep. I feel like you train the battery more effectively by letting it slowly drain vs just shutting it down completely.

I turn it off when I know I won't be using it for a long time.
only when i want it to have a reboot,i shut it down(never rooted)
I just let mine sleep.
which one is better for the battery?
Mine has 10% left usually at bedtime, I plug it in to charge and shut it down while I sleep.
(So its charging while powered off and not draining any while charging)
When I wake up in the morning I turn it on.
Repeat ...
10% at bedtime everyday wow I thought these got like 9 hours screen on time

I throw it in AP mode whenever I'm not using it and it will only drop 5-8 percent every 24 or so hours..
I rarely switch off my Transformer. When necessary I will charge it, but unless I need to reboot for a different reason I let it sleep. Actually, I don't think I have left it to go to sleep by itself, I always turn off the screen when I put it down.

After being on the charger after 7 hours as soon as I take out of the charge my battery his down to 98%. I made one phone call of 2 min and 3 txt messages and it dropped another 1 percent. Before this charge I let it fully drain. Anyone?

I experience the same results - When the phone is powered off and on the charger, it only goes to 98% (according to the settings-->about phone-->Status-->battery level
However, if you turn the phone on, and charge, it will reach 100%..
this is insane... my bat is down to 93% and since the first post to now i haven't even USED the phone... i think my phone is not going into full sleep whatsoever. I uninstalled 3g watchdog yesterday as some people mentioned in other forums that sometimes it wouldn't let the phone go into sleep mode. No kidding... that i only noticed this dramatic change in battery time after i installed LauncherPro. when i was using touchwiz on my second charge the phone lasted a full day with moderate use and i didn't even drain the whole battery. Yesterday was the first day i left the battery to die, i had this phone since last friday.
I was experiencing excessive battery use when I was running LauncherPro. I switched to ADW.Launcher and it went away. I also use JuiceDefender to manage connections while the screen is off. It disables data connections and turns them on for 1 minute every 15 minutes to update any data streams & then turns the data connection back off. I can get around 14 hours of light to moderate use now.
to check if your phone is properly sleeping
Plug into charger
Unplug and hit power to turn screen off
wait 5 minutes
hit power to turn screen back on
using spare parts or any other application which shows battery history(battery leftwidget)
check: Running%
It should be less than 10% for someone with a ton of background apps or widgets
It should be less than 5% for someone without a ton of widgets/bg apps
During normal usage it should be within 10% of the screen on %
Exception to this is if using something like music player
100% !!!!! I installed awd bedore doing this test and had no widgets running whatsoever

Alright like most people I hardly ever bump charge because I charge my phone at night and wake up and leave the house
Well since I'm assuming most people have a similar routine maybe someone can make and app that would turn off the phone when it displays a full charge to let it charge the rest of the way
Or what would be even better if it could have a pre set timer to restart the phone after the bump charge ic complete
Just a thought

I've never used it so i'm not sure but you can probably make tasker shut the phone off when it sees a full charge.
I've thought of the same thing about this but I use my phone as an alarm clock so i can't do this.
getting the phone to turn back on after the bump charge probably isn't possible since there's nothing running. maybe it would work in the hibernate enabled sense roms but i'm not sure if bump charging works or not in that mode.
If, unlike Baram and I you don't use your phone as an alarm clock, you can charge it while it's off.. Then when you turn it on it will be full capacity and you will have no need to bump charge
yea, my phone is my alarm so that dosnt help me.
Charge the phone off before bedtime. works for me.
I was thinking about something along the same lines. Have the phone turn off after its 100% charged, and then let the phone charge again, lastly have the phone turn on in the morning. But it's true, since the phone is off there are no services running and the phone will not able to turn on by itself.
I haven't used Tasker, but I guess it would be able to turn it off when charge = 100. Now only if the phone turned back on in the morning before my alarm....hmmmm.

I'd make sure to put a condition so that if your phone gets recharged during the day, that it doesn't turn off. Maybe power off if battery is 100% and the time is between midnight and 6am for example.
I was half asleep when I typed this so I didn't realize if I just turned it off before I slept it would charge
Im running desire z so I am.curious if hibernation actually does a full charge, ill test tonight
But if it does it would be cool to see an app to turn the phone off at certain times and re awakes it before alarms go off
It some older Nokia phones I had this feature was built in so it would awake when there was a alarm or phone call

Sounds like a plan. Also, MorphiousGX recommended SuperPower (http://forum.xda-developers.com/showthread.php?t=807989) in a kernel thread (http://forum.xda-developers.com/showpost.php?p=9722089&postcount=360).
One alternative is Reboot Manager

Reboot Manager (available in marketplace) will allow you to set a specified time when you want to reboot or power off your Dinc. It will not power it back up, so if you rely upon your Dinc as an alarm clock, this isn't the approach.
If, like me, however, you keep the unit plugged in all night and use something else for an alarm, you can set it to power off the Dinc sufficiently early that by the time you arise, the bump charging has completed.
I have no affiliation with the developer; but I like the product and it solved the bump charge issues for me (except for when I travel...'cause I use the Dinc as my alarm....)
This works in VegaN - YMMV...
Settings -> Wireless settings -> then hit the menu button, and choose "Advanced", then select "WiFi Sleep policy" (It was set to NEVER!)
Spare parts showed (via 'Spare Parts' app) that the WiFi was on 100% of the time - even while sleeping..
I'll give this a try tonight when I go to sleep.
I like to leave it at "never" so that there is no delay upon wake up to connect to wifi. With the table in use (vs. sleeping) the battery life is so long; almost 10 hours, I don't worry about a little battery drain while sleeping. Just connect it to the charger once a day or less.

You get a 'little' battery drain while sleeping? If I leave my gtab unplugged overnight, it loses about 4% per hour.. or about 30% overnight. That's why I'm trying different things. 30% overnight isn't a little to me -- it's way too much.
A tablet like this should all but go into a state of suspended animation while sleeping...
30%, really? That sounds as if there's something else going on rather than just wifi draining.
Edit- Some thoughts. There are some apps that require permission to update or snag some ads from the net and operate on their own.
Go take a look at what you have installed and look at your screen timeout settings.
If you have CWM and can get to recovery, wipe battery settings and then reboot/charge. Some people drain completely then charge to get to 100%. Some threads seem to show this is a Vegan issue. (Mine gets to 97 tops but as long as battery life is not affected, I'm good)

Just curios, why would you leave it on all night when it will never be used? it only takes a minute to boot in the morning when you turn it on.

I leave it in sleep mode because its my alarm clock. I also now leave it plugged in.
I've tried draining the battery then resetting stats in clockwork. If tried about every variation of doing that I can think of short of waiving a dead chicken over it.

I've left mine on and unplugged(it went to sleep) for 3 or 4 days and come back with battery still. 30% overnight seems odd.

I think you might be right, because I used Cyanogen Mod for a month and a half and had no issue like this. Now I am using TNT Lite 4.2.4 and I am still having no battery life issue.
Also I have never been not able to charge my Tab to 100%. So I may suggest that you guys try switching to cyanogen mod or tnt lite.
Ok I have searched and not found anything like this yet so I am going to ask. I know the phone has battery problems all around for a lot of people. Mine seems to be fine when it is on. It can sit and idle powered on all day locked and stay at full charge. It runs about 10 hours with minimal use and maybe 8 hours with some data use and a few calls and texts. Now I am experiencing a wired problem. When I go to work we cannot have cell phones. I leave my phone in my locker and power it off. After my 12 hour shift is up at work I come back to the phone with a dead battery? What could be causing this? And has anyone else noticed this issue?
defective battery? pull the battery and see if it still does it. If it does, gotta be a defective battery.. if it doesn't do it when pulled, you're not shutting off the phone maybe?
Yesterday I tried leaving the battery out. I took the battery out and let it sit 12 hours and it still had full charge when I put it back in. When I go to work I long press on the power/lock button and choose Power off then I watch it shut down and it just dies before I come back. I wish I could watch it the whole time. Today I left the phone off for around 6 hours and came back and it was fine though. Maybe it gets turned on some how at work. I have no idea. Or when I go to power it on it is just the issue where the phone isn't reading battery % correctly and it just says 0%
Seems like a battery driver issue or a defective battery? definitely call t-mobile and check if it's the battery. I've had some issues as well, but not that bad.
Weird.
So the phone powers off after you turn the screen on and it won't come back on? Try putting the phone in airplane mode.
Also, I'm assuming you are running the stock roms?
Might also want to check into a battery monitor to see if any 1 thing is pulling it down.
I think it might just be the battery driver. Sounds like the phone is in suspend so it doesn't power off properly until the screen is turned on and is revived, updating the battery % status, seeing 0%, and turning off.
CM7 fixed the wonky battery issue a few nights ago. Right now, I think a current CM based rom is the best bet as it has most of the drivers fixed. I'ved used mine pretty heavily today, unplugged at 8am and I just got a 15% battery warning at 11:30pm. It will usually last until I go to bed at midnight but I might want to play with it some more.
I've always been reasonably happy with my battery life. If I use it heavily it goes down. If I don't it can stay charged for a couple of days. Within the last week or so that has dramatically changed. All of a sudden it barely makes it through the night from a full charge to 10% or so. It also "seems" that normal use drains it at least twice as fast. Anecdotal but I know something is wrong or different.
I haven't made any changes to my phone for months. I'm running existz kernal for 2.2 and that is the only customization. I did get a bunch of app updates but that always happens. The battery use screen shows the batter is being used for display but over night, it doesn't/shouldn't display much.
Thoughts on how to find what the heck is going on would be appreciated.
Use spare parts app and find out battery stats on partial wake clock usage and sensors usage

What I would do if I were you is charge to 100%, recalibrate, and take the battery out for about 15 minutes before you put it back in and turn your phone on. I dunno.why this procedure worked for me but that's just a suggestion if you don't wanna flash to stock and back to whatever you're using.
Uninstall updates, then add them back, one at a time.

I notice dramatically different battery life when I use this procedure to charge my phone known as a bump charge.
1) charge to 100% or as close as your phone will get while it is on.
2) Disconnect charger
3)Turn off phone
4)Re-Connect charger while phone is off
5) Wait until the phone says 100% charged while it is off. You can check the charge by using the volume buttons if the screen is asleep.
6) Unplug charger. (This is important. If you boot your phone with your charger plugged in it can give you inaccurate battery information.)
7) Boot up the phone.
That is really odd but mine has started doing the exact same thing. I have never had battery issues and for the first time today my phone was completely dead within 6 hours, and the past week it seems to hardly make it 12 hours.
I was just assuming it was the launcher I was using but I removed it and it never helped whatsoever.

I would agree with you on that but... I really have no idea what all got updated and don't know how to find out. the perils of auto-update I suppose.

I'll give that a try... it made it through last night in pretty good shape though. Confused I am.
Not sure if this helps or not, but here is my experience.
I have two wireless routers in my house. One I keep locked to N-only and the other to G-Only. The N router I have suspected for some time has a weak or flaky radio because I can watch the signal strength fluctuate wildly over a period of 10 seconds or so. I noticed a while back that when my phone is connected to the N router it will kill itself pretty much overnight. When I disable that connection and let it connect to the G router it only loses a couple % over an 8 hour period.
I don't know if it is due to being connected to N, or if my suspected flaky router is causing it to use more power staying locked onto the signal or something of that sort.
