I am still a noob on these boards, so forgive me for weighing in. I have gone from Stock T-Mo to Overcome 1.6, and the battery went from so-so to superior. I figured, what the heck, I'll wipe the stats on the GB Overcome upgrade, and battery life will improve, right? Well on the contrary, it now drains about 1/2%/minute. Not a very impressive showing. I am running a few widgets like Daily Briefing, and have those set to poll every three hours. I have done one full discharge/recharge, and had moderate improvement, but I would do anything to get back the battery life I had before the upgrade. I use the SGT as a road-warrior tool (email, pulse and other e-readers rather than movies) so I am convinced I should be getting more than sure 6 hours on a single charge. I am not going to open the thing - my luck I won't be grounded and I will brick it the old-fashoned way!

If anyone can recommend the battery callibration tools to try (Darky mentioned this in an earlier post but did not say which ones), I will give those a shot to try to get a handle on this.

Thanks all
[Galaxy Tab General] johndwstark:
The only other thing I could suggest before you try opening it is to write the battery stats from the CWM menu in recovery mode - charge to 100%, switch off then let it charge to a true 100% then write the stats.
[Galaxy Tab General] johndwstark:
Wipe the stats even
[Galaxy Tab General] rich_cathyrock:
Wiping the stats...

Just did so again this am (full charge, power off, let monitor rise to 100%, then quickly booted to CWM while still plugged in, wiped stats, and rebooted, topped it back off to 100% which only took a few minutes then unplugged), let it fully discharge (didn't take too long - was completely wiped out after power on at 7:15am by 1:30 pm - really bad...fully re-charged to 100% - which took almost three hours. Turned on at 5:00, and is now 7:06 and am at 74%, and I am watching it and using it now, and will not attempt to charge again until it is completely dead again. Am on GB OC RC1 if that helps. Was on the 1.6 earlier and the battery was awesome (12 plus hours or more of on and off use for emails, no streaming or other intensive apps that I know of). Thanks for the assist! Will let you know how I do.
[Galaxy Tab General] Flukturr:
It works for me too.

It usually looks like that: 65%, then drop to 3%!

Today again. So I switched it off at 3%, dismantled, removed battery for 20 minutes, put it back... and battery showed 32%.

Now, after 6 hours and average usage it is at 29%.

Fingers crossed it stays like that!

Greetings,

F.
[Galaxy Tab General] henrylam:
Don't worry, the battery drain problem will not come back again, I can guarantee that :)
[Galaxy Tab General] bongski55:
AFAIK, JQ! is the stock gingerbread rom for Italian GT. The Overcome ROM is a special rom to be installed after flashing to JQ1.....
[Galaxy Tab General] henrylam:
I see, thank you for your explanation.
[Galaxy Tab General] perling:
Thank you:)
[Galaxy Tab General] rokphish:
I had the same problem. Went to Samsung Center and they replaced the battery (still under warranty). They told me some of the Tab with Made in China batteries have this problem, they replaced it with Made in Korea battery. I don't want to open my tab to confirm the battery so I'm just stating this based on their say so. I also read on local forum for the Tab and several people confirmed this.
[Galaxy Tab General] Flukturr:
Yep, 18 days W/O problems ;)

Big Thanks to all of U who are sharing experiences at this great forum!

yup almost is made in china ... china is controlling all the stuff now . whether FAKE or ORIGINAL .. you will never know :D
[Galaxy Tab General] peterkmac:
Thanks to all those who have posted on the battery issue. I was having the same problems with the SGT dropping from 50% battery straight to zilch..............So I sent it to Carphonewarehouse where they swapped it out.............. I did a restore using My Back Up Pro on the new device & started having exactly the same problems again................. So my thinking is that something in my old setup caused the issue. Anyway I then did a hard reset and reboot and installed all my apps individually and now I get brilliant battery life 16 hours on the first day. I do lots of partial charges with my SGT in the car during the day and was thinking that may also have caused the problem in the first place. I will report back if the battery issue returns after a few days of in car use..................
[Galaxy Tab General] jeromejeremytay:
Henry, samsung somehow removed my battery and put it back again. But the problem is partially solved i must say. Last time i had a sudden drop from 69% to 1%. But this time, it dropped from 15% to 3% after few minutes of using without bothering the signal which says connect to charger when it reaches 15%. So, any comments on this?
[Galaxy Tab General] henrylam:
Hi Jeromy, I didn't encounter this problem so far, can I know if you are using any battery stats monitoring widget? If so, can you try disabling those widget and see if there is any improvement?
[Galaxy Tab General] muss:
to hand2leg:

You must to hard reset your Tab (factory default) and problem will disappear... It's Android bug. I had the same problem and it gone off after HardReset.
[Galaxy Tab General] nichas:
I tried doing hard reset, but nothing has changed. Yesterday again it went from 50 to 3%. Now have tried the reset using power and volume up key. Later if that doesnt work, i will try to open the casing and remove the battery as Henry has said.

If trying the reset, gets me out of the problem of this sudden drop from 50 to 3%, i will reply with that updates.

It was very helpful reading the threads of this post.

Thanks
[Galaxy Tab General] henrylam:
Hi Nichas, do keep us update and all the best :)
[Galaxy Tab General] thangbom:
I have the same problem, and still hesitate to open it, because I have not got enough tools to do this operation. However, Nichas, keep me/us posted please. I am curious, because my battery is operating in a very funny way
[Galaxy Tab General] thangbom:
Is this true, and do we have the right to get the battery replaced if still under warranty?
[Galaxy Tab General] thangbom:
Any (positive) news so far, dude? I am dead curious...
[Galaxy Tab General] thangbom:
Update news on Battery Fake Status problem: As many of us mentioned on the sudden drop down of battery rate, battery does not charge, etc., last night and this morning, although my battery indicates that I was still at 25% battery, whenever I make a all, or receive a call, it completely powers down!

I brought my GT P1000 to Samsung Service (I live in South Vietnam), and it seems that Samsung staff know of this problem. They did not say much, but simply replace my battery with a new one within 15 minutes. They asked me to give this new battery a full charge at 8 hours and completely drain it before using it normally.

It seems that some of the Chinese made batteries have this faulty problems, and Samsung was happy to replace it.

Bring your fault battery to them will be my recommendation.

Happy tableting, then...
[Galaxy Tab General] devilng:
seems like your battery calibration file is broken. delete it (google will help you to find it) , make full chrage of powered off device, switch it on and discharge completely. than charhe again and use it!)
[Galaxy Tab General] henrylam:
So long the battery issue is solved, you will be a happy Tab owner.

That is important :)
[Galaxy Tab General] thangbom:
Thanks, it's been 24 hours since I got this new battery, and my GT behaves really good now, like a new one .
[Galaxy Tab General] henrylam:
I'm in HCMC most of the weekdays, if you happen to drop by HCMC, just send me a message, and we can meet up.
[Galaxy Tab General] thangbom:
thanks, dude. I am down in the Mekong delta (Cantho). I'll drop you a message if I come to go to HCMC during the weekdays
[Galaxy Tab General] bovineyard:
My battery will show 100%, then when I reboot it, it will be much lower (30 to 70%).

[Galaxy Tab General] Misoginul:
So could someone put me up to date with the battery problem plz?

Is it a hardware issue or a softer one?

I didn't had this problem before, it started happening like 3-4 days ago.

And I can only think of two possible causes: Overcome 3.1.0 Kratos ROM or the Battery Indicator PRO (which was not really bought ... if you get my meaning).

So what should I do now?

Reinstall the last Overcome version? Reset the Tab to Factory Settings? Take it so Samsung Service?

If I have the Tab Rooted is the Warranty still available?

Thank you in advance.
[Galaxy Tab General] thangbom:
To what all people (including me) who brought our device to Samsung, they simply replaced the battery, and the problem is gone. I am using Kratos right now with my replaced battery, and it works like a charm.

Notice that before replacing it, I flashed my P1000 back to the stock ROM, and the problem still remains. Other posts claims that there is a faulty problem with the Chinese made batteries. Take your to Samsung
[Galaxy Tab General] tryerxda:
Hi.

I bought my Tab in malawi, where the warranty is only six months.

I am now in Europe. How much does Samsung charge to replace the battery?

Is there anywhere I could buy a replacement, and do it myself?

It's a P1000, and has always had battery problems, through 2 stocks and 3 custom ROM's.

Currently I'm on Kratos, and it randomly drops from 60-70% down to 1%. Maybe a total of three hours usage.

I've done all possible recalibrations, including pulling the battery from the mainboard, and even leaving it on the recovery screen untill it depletes fully. (Yes, I know this isn't good for LiIons, but I have nothing to lose)

My current solution is using an external 11000mAh USB battery that I've fixed onto the casing.

Thanks for any input.
[Galaxy Tab General] henrylam:
Hi,

Since you got nothing to loose, I suggest you open up the tab and do a disconnect and connect of the battery by yourself, it's not so difficult as you think. You can refer to this thread as posted by some of us, patience play a part in opening up the back cover, but the end result is worth it :)

Good luck.
[Galaxy Tab General] volcane2:
Hi, I'm Volt , I'm currently with SGTab P1000 for 16 mths now, after my original charger was misplaced, i used third party charger,better quality with 2.1amp same with original spec to charge my tab, recently my charged stayed at 20% even with whole night charging..n sometimes it dropped to 3-5% ,weird...so i suspected my internal battery weak and next day i replaced with original Samsung(China)made battery ,still no changed in charging(stayed at 20%)Again, i loan a original Samsung charger from a friend to charge , still not charging although detected either Third charger or original ....

What shall i do? Shall i flash to stock rom Froyo 2.2 or let it at GingerBread 2.3 ?

I also wipe battery.stat....and google my problems....and my Tab is out of warranty, so i'm not looking at service center............please help!!!I'm trying for weeks now... if i need to flash or try another firmware, i still need good battery charging first............somebody , please help !!!!!
[Galaxy Tab General] tryerxda:
Thanks for the reply, but as I stated in my post, I have already tried pulling the battery from the mainboard, even tried with depleted and full battery.

I'm still looking for a new battery online, but still no luck.
[Galaxy Tab General] texasreb:
There is a lot of tab batteries on ebay. Just search galaxy tab battery on ebay.
[Galaxy Tab General] texasreb:
I finnally got sick of my galaxy tab losing power and removed the battery connector. We will see if this helps.
[Galaxy Tab General] tryerxda:
Quick update:

I managed to get my battery working again.

Note: You shouldnt do this. It worked for me, but it will blow up your phone, hack your bank account, and will call down aliens to probe you, if you try this.

1- Started using fully charged battery. Let it drain down as slowly as possible, all radios off, screen dimmed, sleep off, cleared all apps, forced with app killer. Took 3 days.

2 - Charged with tab off, using 350mah usb wall charger, using non official GTab cable. Verrrry slow. Left it charging for about a week.

3 - without turning it on, opened it up, removed battery. I then pressed all the buttons various times

4 - (this is the step that will give you some undiscovered uncurable disease)

I shorted the battery connector on the Tabs MoBo for about 5 seconds.

5 - reconnected battery, closed it up, Charged it for 2 days with official charger + cable.

Booted into recovery, deleted batt stats, Booted up.

First runtime was 18 hours, about an hour of youtube, another hour browsing, 3 hours music, and about an hour of Robodefence (a battery killer.for me usually)

Very pleased with the results, am now gettin around 18-24 hour runtimes. :) yay!
[Galaxy Tab General] tngoc:
I have found another solution, at least it works for me.

When my tab suddenly drop to 1%, I continue using it until it turn off automatically. Then I charge my tab 8 hours without turning it on. And now, This issue haven't come back for 2 times charge
[Galaxy Tab General] devondoc:
Battery problem finally resolved

Huge thanks to Shimji and Henry Lam. After 6 weeks of my battery dropping charge and behaving weirdly I finally plucked up the courage to open my tab and disconnect the battery. Like many others I tried countless software work arounds flashing roms, resetting battery stats, etc...none of which worked. Reconnected the battery and now my tab is working fine again. Really grateful to all on here, many thanks !!
[Galaxy Tab General] lebdiabolic:
Hello guys

I opened my tab and did the same process but it did not work for me.

What I did instead is leave the battery to die and let the TAB shut off itself. Then I charged it while shutoff and turned it on when it was fully charged. I finally got the battery to show full. However if I charged before emptying, it wont show the charge up. It will keep the low battery level shown and will continue to drop. I have to let it turn off again and charge it back while shutoff to enjoy a full battery?!!!? :confused:

:cool:
[Galaxy Tab General] testadeferro:
weird

My battery status acts weird.

When I root a rom the status and the battery drains in one hour...

If I flash a samsung firmware the battery drains normally... Even with overcome kernel and stock rom the battery stays at normal drain. When I root the tab the battery flips out. anyone can help?
[Galaxy Tab General] gildow:
+ 1 to the list of people who found henrylam fix!!!

It worked for me...

was having crappy battery life..the tab battery drop to zero percent, and shut down automatically. but I can still reboot it into CWM and see that the battery is somewhere around 30%.

After the fix, everything is back to normal!

Thanks!
[Galaxy Tab General] raman.sherry:
Shinji it works thanks a lot man.i tried disconnecting battry and everythng is back to normal.earlier i tried every calibration method bt nothing works.

Join xda, download android xda app just to say thanks to you.
[Galaxy Tab General] shinji21:
Glad it worked for you man.
[Galaxy Tab General] debernardis:
My wife's Galaxy Tab is having a particularly stubborn battery problem.

Didn't charge except than when off; then it started to refuse to charge even when off.

Opened it, left it without its battery for more than 24 hours, then mounted brand new battery. Same story.

I have done factory reset, wipe cache, wipe dalvik cache, but still doesn't charge.

Time for litter?

I'd appreciate any help, thanks.
[Galaxy Tab General] leapinlar:
Are you using the official charger block to charge? It has resisters between the data pins to put a specific voltage there so the Tab charges properly.
[Galaxy Tab General] debernardis:
Yep, original stock charger and cable. Now it's been some 48 hours charging while turned off. When it reaches 100% I disconnect it from charger, then reconnect a few seconds after, and it shows less than maximum. This has been going on sime three times since I attached the charger. I am waiting for the time it reaches 100% and stays there. Then I plan to reboot in cwm recovery and wipe battery stats.

What else could I do? Is it possible that the charging circuitry got damaged? And, alternatively, might it be a software issue? Should I reinstall the firmware?

Carefully crafted on my Galaxy Note, for your eyes only :)
[Galaxy Tab General] leapinlar:
You do not need to wait for 100%. Just wipe now.
[Galaxy Tab General] debernardis:
Done it several times before, no joy :(

Carefully crafted on my Galaxy Note, for your eyes only :)
[Galaxy Tab General] shantaram77:
Same problem here.

I've even changed the battery without success

Inviato dal mio iPad con Tapatalk HD
[Galaxy Tab General] debernardis:
Tab reached 100% apparently.

Could be switched on in recovery mode only after some minutes.

When in cwm recovery, wiped battery stats and dalvik cache.

Rebooted, showed 0% battery and turned off automatically.

Left alone say 15 minutes, turned on again, shows 100% battery and so far seems to work.

I plan to let it discharge until turns off them fully recharge.

Hope me well :)

Edit: some minutes after, Tab turns off abruptly. Can't be turned on got some minutes. Then, allows to be turned on, and battery apparently is 0%. Turns off.

I am very upset :(

[Motorola Droid and Milestone General] xHVGx:
Hi everyone,

Just as the title says, I have a friend in Mexico who owns a Motoroi which I assume is the equivalent to the Droid 1 here in the US. He's stuck in 2.1 and wants to upgrade to 2.2 and Im not sure if there was an official update or not.

So I suggested him to maybe lean towards a ROM. So, are the ROMs available for the Droid 1 compatible with his phone or will there be a problem? Thanks in advace. :)
[Atrix 4G Android Development] BravoMotorola:
So anyways, someone on the Defy forums developed an app that would put Debian on the Defy. He states it only works with the Defy, but I had to try it out, still.

http://xdaforums.com/showthread.php?t=962974

Also, on his instructions he says to put it on the removable SD card. Don't do that. Actually, take the card out so it's not even there!

1. go to the app, and select 'download debian-img.zip'

2. Wait until it gets to 1% then CANCEL, or BACK OUT.

3. Use root explorer or even the stock file explorer that comes with your phone, and go to the 'debian' folder and delete the contents inside.

4. Use the link he provided to download the image straight to your PC. (it will take for ever, it took me 3 hours!)

5. Plug your phone into your computer.

6. Mount as USB Mass Storage

7. Go into your internal phone storage and put the downloaded debian-img into the debian folder on you internal phone storage.

I just wanted to make clear that the debian folder with the debian-img inside of it must be on your internal phone storage, for the Atrix. And my 'instructions' are for following so there are no mistakes.

Basically, follow HIS instructions, except for that part (where to put Debian)

So, anyways, I find it very cool how you can run Debian on your phone. Some people tend to think stuff like this is stupid and pointless...

And once again CREDIT TO COCUS, AND XDAID.

edit: I used AndroidVNC off the Market and didn't like it, I have found the app PocketCloud to be TONS better.
[Atrix 4G Android Development] designgears:
sweet, now I can dev right on my phone!!
[Atrix 4G Android Development] itsonlym3:
lol

oh wait, you don't have an Atrix. :(

have to admit, it is pretty cool though.
[Atrix 4G Android Development] Clienterror:
Yes DG got rid of his atrix =( I think he's just teasing us!
[Atrix 4G Android Development] dragula53:
Hmm.

I have done all of the steps involved, but debian doesn't seem to boot for me.

I have (on internal storage) a debian directory which contains: debian-img.zip and debian.img

I have the debondroid application, which gives me the "boot debian" and "remove debian" options.

When I launch "boot debian" it grants superuser permissions, but it never completes and I can't VNC properly.

I wonder if I have an application that is interfering, or if I it just isn't working for me for some other reason.
[Atrix 4G Android Development] chbearsrock:
I'm surprised this hasn't garnered more attention. How functional is the device? Do core services (wifi, bluetooth) still work?

Thanks for your effort!
[Atrix 4G Android Development] Ririal:
Make it run in webtop mode ;)
[Atrix 4G Android Development] BravoMotorola:
Yea this happened to me after I accidentally hit 'remove debian'. All I did then was redo everything (re install the app and delete debian img and put it back on) and rebooted an it worked fine. You are definitely not the only one having problems btw. Just look at the Defy forum, there isn't one person besides me who has actually reported it working.

Good luck with it.
[Atrix 4G Android Development] BravoMotorola:
I think it uses what ever connection the phone has. If you are on wifi, then it uses wifi, and 3G it uses 3G. Although I don't think you can actually control the connection through debian.
[Atrix 4G Android Development] Djazin:
Well we should be able to get VNC veiwer running in webtop mode through an xsession config? Though I have no idea where to start for something like that, I would assume it would be similar to the way we were able to get the terminal to run in webtop mode.

Its Alive XD now on to getting it on webtop XD
[Atrix 4G Android Development] Ririal:
Yeah, except at that point the phone would be running three OS's at once, and that's just silly.
[Atrix 4G Android Development] Djazin:
True though till there is a way to get a more versatile webtop then I don't see any reason not to try it, though I did notice even with vnc veiwer not running the debain part still runs within the phone so alternative to the webtop you should be able to get to the vnc through the network within a brower or vnc client on another computer. Either way worth looking into for now till a full webtop, personally Im not up for messing with the files with the webtop just yet.
[Atrix 4G Android Development] Bigsam411:
I tried it and it sucked. Well I just ran the vnc viewer in windowed mode while in webtop. I then fullscreened it and it looked like crap. Also mouse input was not right because it still acts like a touch screen.
[Atrix 4G Android Development] Djazin:
Was vnc running in mobile phone mode or was it in an x session within the webtop, in phone mode...It would look like garbage still wanna try it out in the x session or over the network just to see how it runs. though will have at it tomorrow.
