I set my phone into airplane mode once it was fully charged during night time. Once I woke in the morning (about 7 hours), I saw the battery remained 92%, do you guys think is normal?
The reason I'm asking it is because I had flashed my phone to CM5 recently and if I remember correctly (however, I can't be sure), the battery life was remain around 97% (same as above what I had done) in the original ROM.

Once I swithched from Iphone 3g to my Nexus one, I have set the iphone to airplane mode. I still use my Iphone as a VOIP phone when connected to wifi. Well, ever since I put my iphone into airplane mode, the battery lasts 10x longer than before.

You might have apps and services running in the background and eating battery!!
Boot into safe mode then airplane mode and let us know what its like then.
1. Power the device off.
2. Power the device on.
3. When the logo appears, press and hold the Trackball button.
4. Continue holding the Menu button until you see the home screen.
The words Safe Mode should appear in the lower left corner if you performed the steps correctly.

Thks, will try that
I just couldn't go into safe mode because it just kept reboot my phone :-(
Anyway, I'll just try to disable some backgrounds app, then go into airplane mode and monitor further.

Hiya,
I was poking around the forums a couple days ago and I stumbled across a hack that recalibrates the phone's battery STATUS, it doesn't do anything about helping battery life or anything.
Last night when I was about to go to sleep I had a battery life of 32%. I plugged in the phone, and immediately restarted it. When it booted up again, I kid you not, it had 63% battery life. I turned off the phone while plugged in to see the battery icon, the one that shows.the battery status while its charging with the phone off, and indeed it showed around 63,65%.
Anyone know where I could find this? I think its buried somewhere on the forums.

THIS WILL HELP RECALIBRATE YOUR BATTERY SO YOU DON'T HAVE THAT ISSUE
1.Charge till full when powered on
2.power off
3.charge till full again
3.boot into recovery(adb reboot recovery or Power off the phone and then hold the volume up + Volume down + the power key. When it goes black the 2nd time release the power button and keep holding the volume buttons.)
3.wipe stats by going into Clockworkmod recovery -> advanced -> wipe battery stats.
4.boot and continue to use as normal
Heres 1 from another board:
""So, you are having trouble with your battery seemingly draining too quickly, especially after having flashed many ROMs/Kernels/etc...
It is possible that the problem (or part of the problem) is not necessarily the phone using too much power. If this is the case for you, you should see some results from doing the following:
1. Connect the phone to the charger with the phone powered on, and allow the phone to charge until it shows 100%
2. Disconnect the phone from the charger, and power it off.
3. Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the battery indicator shows 100% (you can use vol-up/vol-down to make the indicator come back up when the screen goes to sleep).
4. Disconnect the phone from the charger and power it on.
5. Once the phone is powered completely on, power it off again and reconnect it to the charger until the battery indicator shows 100%.
6. Disconnect the phone, power it on, and use it.
You should only need to use this sequence one time.
Hope this helps.-Joeybear23"""
Yesterday morning I pulled the TAB from the net adapter. Immediately it beeped and turned off. Plugging it back in, the battery indicator went from 0 to 100% in 5 minutes.
Turning it back on, it died in 10-20 minutes.
Turned it back off again, fully loaded it again and played a movie on it, 50% back-light. It lasted for just 20 minutes.
I made a backup to SD, did a factory reset and charged the unit (powered off) to 100%.
Did a restore, and everything worked again.
Battery is still working at 80% after an evening of restoring apps and a night of stand-by.
What the heck happened?
perhaps one of your apps? try installing them a few at a time to see which app is causing it

I also think it's a software problem, after the problem disappeared with the factory reset.
I'm going to check slowly which program is the culprit.
I just can't imagine that a program can stress the TAB so hard it realy drains the battery.
I think it could probably be a misguidance of the android OS from a wrong setting?
I had a similar problem but not nearly as bad as yours. I had my tab unplugged for a while and checked the batter: 30%. So that was fine so I opened up dolphin and INSTANTLY the screen went really dim and said I had less than 3% battery which I did not believe.
Turning the tab off and back on the battery was now at 27%. This only happened that one time and I havent seen it agian. Must be some weird battery level reading bug.....
I have the same situation and also make a backup and factory reset amd later a restore.
That was 2 months ago and until now it works like a charme.

Power off g tab drain the batt
I have my Galaxy Tab for about 3 days ago. Charge to 100% the battery, and then, I decide power off (totally) the Tab. Hold power button, and in the pop-up window, power off the phone!!
After a 1 hour, I saw the screen message with the android icon "POWER RESET or UPLOAD MODE"....and drain totally the battery!!!
What can I do???
See the attached image.......please help me!!
Only 2 things are likely to cause this, the battery being stuffed, or the battery stats database getting corrupted. You could try the "bump charge" method and see if it resets it. (Charge fully while on from AC, unplug, turn it off, charge for an hour or so from AC, unplug, turn it on, turn it off again once booted, charge for another hour or so, unplug, turn it on).
The battery stats can be wiped from the CWM recovery if you wanted to flash that, I'm not sure where the file lives to do it manually.

Hi, just like to share my experience with you guys. I encountered the same problem as mentioned, especially the sudden request to shut down due to battery becoming 3%, although it has 50% left. I tried recharging a few times but the same thing happens, something, it will shut down at 30% battery power level. Then, one afternoon, while I was looking at my pictures (at Gallery), I saw duplication of my photos (3 times) that appeared on my gallery folder. But the key issue is I stored all these pictures (taken by camera or by transfer from PC) in the microSD card (8GB). I tried to do a deletion on the addition pictures (it showed 3, so I tried to delete 2). But to no avail, and the system keep processing even though I tried stopping it. After about 2 minutes, the promot came up, requesting me to do a shut down saying the battery level was low, although I have about 50% battery power left. So, I shut down the tab immediately and removed the microSD card. After that, I switched on the tab and it says 50% power left. But I have to make sure it is possible to utilize the tab until it drains out the battery. Finally, I managed to cross the 20% power level and the tab can still be used .
I was curious about my microSD card, thinking that it may be faulty. I used a pc to open up the content and I discovered the SD card has no problem at all, it didn't have duplication when viewed from the pc. For your information, I have installed "angry bird" onto the 8GB microSD card, I am not sure if it is causing any problem to the tab or draining power from it, because the download (from Goggle market) mentioned something about "preventing phone from sleeping - System tools". I am not sure how this is link to the duplication of the pictures in the gallery folder as well, but I am glad I have found the fault to the draining of the power by the tab.
I would suggest, before anyone proceed with the factory reset, do a check on your storage card or the apps that you have installed in your tab, try to solve the simple way and it can save us a lot of troubles .
I hope it helps............

As knightnz mentions ~ It's the Battery Stats Database being corrupt.
To repair, simply:-
Connect the Tab to it's Charging Cable and ensure the Tab is switched Off.
Next, hold the Power On Button whilst at the same time touch and hold the screen.
You will notice the battery indicator will pop up.
The Tablet will now reboot.
Everything should now return back to normal.
This procedure can also be used for a Tab that refuses to switch on.
Should I do this when the tab is off? or when it is on?
I actually tried both, but I dont see "the battery indicator pop up" as mentioned.

Actually, I missed out an important ingredient ~ The Power Cable.
You need to have the Tab connected to your charging cable as if you were charging the Tab and the Tab switched Off.
Next, hold the Power On Button whilst at the same time touch and hold the screen.
Next you will notice the battery indicator will pop up.
The Tablet will now reboot.
Everything should now return back to normal.
I'll amend my previous instructions to include the Power Cable.

Hi Beards,
Sorry to ask again, is there any way to verify that it has been solved without really draining the power to 0%? Is there any clear indication?
Thanks.

The trick is in holding the screen whilst powering up.... It bypasses the normal start-up routines, resetting any errors that would sometimes require a Factory Reset to correct.
This info was passed on to me by a Samsung representative.
Easy fix, get a replacement, thts bad hardware, shouldn't have a problem exchanging, assuming it was purchased thru an auth retailer. No sense in messing with software and having a headache over it.
Seriously, the press screen thing doesn't work at all. Eventually, I brought it to the service center to do a firmware upgrade and it is back to normal...............
New upgrade:
Baseband version: P1000DXJM2
Kernel version: 2.6.32.9 [email protected]#1
Build number: FROYO.DXJM4
The funny thing is my wife has a unit that was using the same version as mine (old version, we bought them at the same authorised dealer), but she did not encounter such problem. I am just puzzled.
It did not work for me either. Is the charging cable supposed to be plugged in to the power socket or just the cable? (I tried both and neither worked)
I also did a firmware upgrade with Roto JMIv2. And I still see the problem.......Anyone having any suggestions please?
If your GALAXY Tab is running from fully charged to flat in under 20 minutes I wouldn't recommend anything other then... Sending it back to where you go it from?!
It doesnt go flat in 20mins. As a matter of fact, it lasts a couple days with my work load. Its just that when i put it in standby mode let say overnight at 80%, when i turn it on in the morning the battery will be at 50-60%. But when i restart it will go back up to 78-79%.
So im not losing battery capacity here i believe, but its annoying to have inaccurate reading, especially when i am on a trip or sth.

I can understand your predicament, I have those "moments" before. Mine just dies off and need reset to get the battery back. The unknown is always not welcomed to all since we paid so much for them.
Hello guys!
I stumble from time to time upon a phone that does not want to start. I mean the only thing I can do is go into download mode.
No recovery whatsoever, no boot, no booting screen, nothing at all, only download mode by pressing vol down + home + power.
The only thing I've figured out to get it work again is to deplete the battery (in download mode) and when I plug it from battery at 0%, I can boot it again.
The only hmmm... should I say symptom here?... I see is that it never (or very scarcely) get into 'charging' mode. What I mean is it can charge up to 100%, but when I go to see the battery usage it is like power comes from nowhere. The blue line for "Charging" is black and it is as if my phone was on battery for 6 days with downs and ups in the graph.
I have tried to go back on cm7.1 stable for some time and sure enough, one day I can't reboot my phone. Every time I have to power it down I'm like "Oh! Power of the Universe, please, PLEASE, make it so that my phone will power up again, soon, not in a few hours... Please?"
Oh and to make things worst, I can't adb my phone anymore, nor can I use Odin... I have tried Google USB ver 4 but it doesn't want to install on my win7 64.
I'm now waiting for cm9 or teamhacksung's port to be more stable and see if it will solve my problem. But since then, I'm just wondering if there's something I could try?
Hi
So I have an Acer Netbook, the D620.
Earlier, I closed the laptop (not shutdown)
and as usual the CPU lights went off with the power light flashing indicating standby.
After an hour or so, I saw all the lights except the WiFi one were on, (power CPU and Ram) . When I opened the lid of the laptop, it didn't come out of standby mode. Just a black screen
I did what any Android user would do. Pulled the battery. It rebooted fine.
This has happened like 5-6 times now. Any ideas?

Reinstall Windows(or Linux or whatever you have on there). Works every time.
What you have to do is smack the keyboard really hard at least 2 sets of 10 times. If that doesn't work, then you have something running in the background, which makes your laptop wake up. When you open it, just wait a minute and it will turn on.

I waited for an hour. Nothing happened.
That was your laptop going from sleep to turned off. if that happens again dont just pull the battery, just press the power button and hold it for about 10 seconds. once its off just press it again to turn on.

It doesn't go from sleep to turned off. It goes from sleep to lights on but blank screen mode.
I need it to stay in sleep because overnight it switches itself on and by morning I have 10% battery

then there is something that prevents it from turning off or hibernating. Go to your power settings and make sure that there is nothing like turn off after 1 hour of being in sleep mode or something like that. Why arent you turning it off or putting it in Standby mode? Standby still resumes fast.

You can use the power settings and tell the laptop to go into standby when you close the lid.
And make sure you have hybrid sleep mode disabled.

I had to reboot mine in to flash mode in order for mine to come back up. I had to hold the down volume (or up cannot remember right now) + power for a minute nearly. Then it rebooted correctly into normal mode.

So I ended up calling AT&T and they went ahead and shipped me a new MAHD.
I took the dead phone to work and tried charging with my work charger, and now it works! When it finally turned on, the battery level was at 3%. So lesson learned: Do not let your battery drain to 1%!

I am having the same problem. I can get the boot screen up if i hold the buttons in at a certain time while the phone is plugged in and attempting to turn on. however, the phone cuts out no matter what and repeats the cycle even with the boot screen up. during the few seconds i can get the boot screen up, i'm unable to select an option, only scroll up or down and highlight them. then the phone cuts out and 20 secs. later attempts to turn on again but never gets past the motorola icon. Any suggestions? I originally thought it was the battery so i ordered one and installed it correctly and charged it, but still the same thing is happening. When plugged into a pc, charge light comes on but phone won't attempt to turn on....?????????
