Anyone out there notice that on a completely full charge using the AC charger, the minute you pull out the charger, the batt indicator on the TAB will drop to 99% ? The 100% only last a couple of seconds!!! No apps running , wifi, BT, GSM is all off.
Is this normal ?
Yup. Same thing happens here. I think it's normal. Same thing happens with my mobile phone.
Thanks.. but this never happens to my mobile phones and that includes Samsung Omnia, Omnia II and Omnia Pro..
As soon as i pull my plug i am showing 98%.
Yep, I was wondering that too. It goes straight to 99%. I guess it's some bug, it doesn't really go to 99%
It's just rounding down, but think about it:
The moment you unplug it, you're consuming battery power.
If you've consumed any battery power, it can't be at 100%, now can it?
I really don't see the problem with it dropping to 99% .. really i don't !!

Any number of ways, but I have been using the "Batterylife" widget from curve fish on the market.
Thanks i installed it. I noticed that my battery drains quiet quickly, my tab was in stand by mode for 30 to 45 min and i battery drains by 9%. I just bought it this afternoon could please guide.

With a lot of android devices the battery is not calibrated with the system, there was a post on how to do this with a nexus one. i used it on my vibrant and it worked the same. it was a series of steps like plugging the phone in, powering off, powering on, unplugging again, weird stuff like that. and it actually works. sorry i dont know where the post is or the exact steps to do.

I did this for my captivate and works well:
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.
Hey, it doesn't happen to me so you must have something else going on.
The only thing that matters is how long the battery lasts between charges.
The percentage of charge shown on a battery gauge widget is meaningless unless the battery is draining abnormally in relationship to the way the tab is being used.
I find that my tab drains from 99% to 60% in about 2.5 hours with wifi on, GPS on, bluetooth off. It then takes another 4.5 hours or so to drop from 60% to about 10% under the same conditions. So... 7 hours of continous wifi on web browsing isn't much to complain about.

exactly..
Most modern electronic devices on Li-ion batteries do this. When the device reaches 100%, it will stop charging to prevent damage to the battery. The battery then drains to 90-95% and the charging circuit allows the battery to charge again. Most systems hide this by displaying the battery level at 100 or 99% for a while after the device is unplugged. Hope this helps!

so strange, i think this is not a fault of battery, because lithium polymer battery is really long lasting, have you connect your x1 to computer, please connect your x1 to charger and wait about 1 hour. but maybe it's the fault of mini usb port, can you sync your x1 before it happen? in your case, bring it up to guarantee service is the best solution, what did you do before the device turn off?
Leave it on the charger, it could take about 15 - 20 minutes to start charging if the battery completely died.
i used a wall charger, and a computer charger, still no luck...i wasnt doing anything, i was playing a game and shut the game off started browsing through the fone, and it just shut off after a few battery low warning sounds. but the red light goes on after a wall charger, but nothing when i try to turn it on, it doesnt turn on, and when i unplug it to try to turn the phone on, the side lights flash red...i have no idea whats goin on but i got the phone today and its pissing me off already i spent 680 on the phone for a peice of crap...

ah, you should keep it in the wall chager a bit longer, and don't use the computer charge at this time, when the battery complete die, you should keep it charge about 10 minutes before you can start it, don't worry, when you can see the flash light turn red, it's charging, wait a few minutes more, it's will work, just forget about it, go somewhere, when you comeback, push the power button:d

was had same problem.just leave it charged.i leave it charged into usb drive,and it needs 5h before he turn on.battery was completely dead,like probably you have too.just leave it charged throught the night.
Charge some time and then remove battery cover and try to reset. as u mentioned lights are flashing when u r trying to switch on so just reset.
The X1 of my colleague had the same problem and he had the battery replaced by the vendor, no questions asked as it was dead after only 2 days...
Charged without battery...

Hi, I got similar problem and I called the support guys.
They advised me to remove the battery and charge the phone for 30 min and charged with the battery for 1.5 hour.
He claimed is some 'internal battery' stuffs.
Anyway I tried and it works.
In addition, I charged the battery when the level hits a minimum of 20%.
So far so good
Good luck.

That Solution worked for me as well. I was in Germany with some navigation software to find my destination address. Than suddenly my phone died, I thought. So I was stuck somewhere in the middle of nowhere.
hey xda friends,
i have a small problem with my batterie /charger.
it is charging very slowly i am running cm7 so i plug it in very often yesterday at 6 pm it was almost flat so i plugged it in but keep on chatting and surfing/reading so battery wasn't gaining and it kept reading 5% (same as when i plugged it in) i thought well it's just usb so i use a lot of power and it keeps it's level
but when i got to bed (1am ) it let my wallcharger do the task
today when i got up(6am) i looked at my phone and it only read 80% (before i deplugged it) perhaps somebody knows the problem (battery /phone) i have just original parts (charger and battery) i am running cm7 for a while (yesterday i just switched to 2.3.3) never had this problem before....
i tried
power off
power on
pull battery
wipe battery stats
....
thank you for your help
Could it be you have something draining the battery heavily?
try a full wipe then reflash

no new installed apps and unplugged it drains normally
Pull the battery, and with the battery out hold the power button for a good 30 sec, on most hardware these days this is how you usually hard reset the power management unit. Try it and lemme know how it goes.
i dunno if this will work for SGS but i guess you have nothing to lose.

push it real good nanana
if the battery drains normally.. .. then perhaps it's the charger itself (???)
I was seeing something like this but not as drastic. Tried a different wall plug and things were better.

I have a similar problem. My phone also never charge to 100 percent. It reaches to max 85-90 percent and if i continue to charge it starts discharging. If i let it to charge till morning, when i disconnect the charger i read 65-70 percent. I have another battery but not original, it behaves more weird. Dont know if the battery is problem.

I have tested with the wallcharger. It charges to 100 %. And the phone battery drainage is normal. Like 2 days.
Remaining possibilities.
1) Firmware problem. Reflashed the phone with the new firmware. I will see if it changes anything. Not likely though.
2) Hardware problem. The phone's charging usb part damaged and there is some kind of disconnection.
3)May be bootloader got damaged??? Even if the phone closed, it doesn't charge to full capacity.
Edit: The problem seems to be the second one. While flashing with odin it failed many many times. I was just scared that the phone was brick.
Then i realised that the connection with odin is not stable. I press with my finger the the usb charging cable to left and right and I have seen that
the connection comes and goes. After that i have succeeded to flash the phone while pressing to the mini-usb part with my finger. it seems that
that while charging also the connection is not stable so it never fully charges.
i just got the phone nad first charge i charged it whe ni got it and now its dead im charging it battery is very weak compared to nexus one i had.... but is it true that if u discharge it completley and then charge it completey and repeat 3-4 times battery gets good? i also heard over a little time that battery gets way better? any one can relate to this?
Sounds like you could benefit from re-calibrating your battery. It can be done manually through recovery by resetting battery stats, or easily through an app like this one (you must be rooted).
how u do it without rooted and i heard discharging 3 times and fully charging works? any update on that
There's lots of different "methods" floating around about how to calibrate your battery, many of which actually don't make much sense. The ones that do make sense to me involve deleting the batterystats.bin file. That app TeeJay3800 linked to pretty much does just that. For rooted devices, all the ClockworkMod recoveries have an option to delete battery stats in the Advanced menu.
I think this file is located somewhere in /data but I don't know off the top of my head. I also don't know if root is required to delete this file. Maybe try finding it with Terminal Emulator and attempt to delete it. If that doesnt work, then you'll probably have to root the device (or maybe just temproot it).
yea i did it yesturday nad today its still bad about to attept 3rd charge and im waiting till it dies it went from 39% to 19% within an hour wtf is this??? im waitign till ti dies then recharge to fully
i also did this wthich is good but will it mess anything up if the phone is brand new and is charging fine
Connect the phone to the charger with the phone powered on, and allow the phone to charge until the notification LED is green, indicating the device is fully charged.
Disconnect the phone from the charger, and power it off.
Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the notification LED is green.
Disconnect the phone from the charger and power it on.
Once the phone is powered completely on, power it off again and reconnect it to the charger until the notification LED is green.
Disconnect the phone, power it on, and use it. You need to use this sequence only once.

This is "bump charging" and all it does is try to fill up your battery as much as possible. It's like topping off at the gas station. It won't do much as far as battery calibration. You may see a minor improvement in battery life after a bump charge, but you'll have to do it each time you charge.
Keep in mind that battery life is dependent on many factors, including your usage pattern. Improving battery life is a matter of being mindful and selective about what connections you leave open (bluetooth, GPS, WiFi, account sync) and what apps you let run. Screen usage plays a role as well. Network signal strength also plays a part, but that's not something you can control. Don't use taskillers, they cause more problems than they solve.
I'm assuming you're still on the stock ROM. If that's the case, you should be aware that there's lots of extra stuff on there that runs in the background to support the HTC Sense overlay. The biggest improvement in battery for me was (a) flashing a custom ROM without all that junk on it and (b) flashing a custom kernel which both underclocks the CPU and uses lower voltage settings.
If after all these considerations you still think your battery is borked, head over to a T-Mobile store. They may give just you a new one, otherwise it'll probably cost you not very much.
Hi, all..
I'm having Severe Battery problem with my HTC HD MINI..
It cant stand even 1 minute when I unplug it from the Charger..
Did anyone suggest me what the problem is..
dude buy a new battery :good:
if your running android then go into recovery and run "clear battery stats". or use a app from the market a good one is this one http://j.gs/1hOC

If it is really just standing for 1 minute, then it's your battery's problem! But if you've just enlarged the problem, you can calibrate your battery by charging it to 100%, then unplugging, let it drain the charge to 0% and turn off automatically. Try to turn it on without plugging till when it can't get turn on anymore. Then without turning it on, just plug it and charge it again to 100% (The LED goes to green). Then you can turn it on again. This may help!

borrow/buy a battery and try it, if the problem still apprears, then it must be the phone in problem...(((
the phone works in recovery mode without charging.. but it doesn't after booting
i was used to try for hours to get my phone back to life after it shut down due to poor battery level, but now while it was fine the battery heated a lot and the phone powered off and after one day of tries i have still not succeeded to get it back on. when I plug it to the charger the device powers on and after some time it shows only the big red battery gauge, 1%. then sometimes it reaches 2% and after some time the part of the phone above the battery gets much hotter, though not as hot as the battery did earlier, and the gauge falls to 1%. I tried to keep it plugged for one or two hours and it shows only 1%. Actually it seems that the phone is configured to power on automatically as soon as it is plugged to an external power source. Li-ion batteries normally need to be recharged at very low rate when they're at very low level, though this is a dangerous case, so if the phone keeps powering on, the charging current might not be enough to over-compensate the drain.
I'm asking here because i'm wondering whether rooting the phone has anything to do in it, and if there's a special combo that could disable the phone from keeping powering it on every time it is connected to an external power source. I'm currently searching a way to get the battery recharged with an external charger.
