Hi
I have a pretty serious problem with the battery life on my tg01! I've read the other threads here and at Modaco on the battery problems but thought I'd raise it again. I have a mugen battery now (1100) but am barely getting a couple of hours use. The battery indicator gets stuck and can go from 100% to 40 suddenly, before a few minutes later switching off. I have the original wm 6.1 rom and spb mobile shell 3.5, but the problem was there still when that was uninstalled. I can leave it charging overnight and the battery can suddenly drop and be dead in a few hours.
I'd have thought mugen battery, although only a 1100 one would have made the difference, but there's something definitely wrong because it should not be that bad!!!
What do you suggest is the best thing to do?? Will a different rom definitely solve it? or will it be down to one of the numerous programs I've installed? Or something else? A faulty phone?? It's a problem others definitely have, but is there a single working solution??
cheers!!
as far as i know battery life is a problem with all tg01's, atleast i have the same problem. the huge screen takes alot of power, add 3g or wifi and your phones going to be dead within 2 hours ! one way to overcome this is to make sure you disable data connections when not needed and reduce the backlight settings. i've been able to get over 24 hours using this method but if you want longer life the only real solution im aware of is to get the 2600 mugen battery.
EDIT: I should also mention sense and other memory hungry apps ie opera will effect battery life greatly, infact i find if i use sense my phone can be dead within 8 hours and thats with minimal useage. Constant use of opera will have the phone drained in a matter of an hour and a half.
As for a rom solving it, i dont really think its tied to a rom in anyway but you may want to try noskers rom - i find this one to be the most stable and battery life definately seems longer but i may be imagining that !
Get Task Manager, go to tab "Devices" and stop device "BAT1". Battery indicator will not work, but you can use tg01 till battery fully discharge. After power off (there will be no "shutting down" screen) plug charger immediately.
By this you will use all the capacity of battery, so you can determine if it's battery problem or tg01 battery level measuring circuit.
I've heard about battdrvr.dll modifications for other PPCs to use with higher capacity batteries, but couldn't find anything for tg01.
What Power Saving Settings do you use?

will try that definitely. it happens with the new mugen battery too however.
The Power Saving Settings I use are CPU medium (have tried low and high too), limit CPU speed for battery (tried on and off options) Wifi power consumption, restrict sleep mode OFF, Enable Wifi during sleep mode to OFF, backlight very low. Adjust backlight automatically OFF, 30 seconds backlight timer, 1 minute device sleep timer.
I am guessing there is a rogue program using up the CPU constantly running down the battery. Have you tried a hard reset? (probably a good idea to upgrade the ROM while your at it )
Well I've tried disabling the battery device in task manager. I'm not sure that made a difference, but at least I wasn't able to see the meter jump around..
a hard reset may well sort it, and may end up doing that. I can't see any high intensity CPU programs. anything else? will google latitude suck up the battery this quick?
One other thing which has started recently, which may persuade me to hard reset is that the blue led light flashes long after an sms has arrived. a soft reset stops this, but it will start again when another sms comes through. I've tried one such notification reset program on this forum but its made no difference.
what can be done to stop this?
Edit:
I should really have considered another post really called niggles I need to sort out on my TG01.
But how can I stop the screen going off immediately when a call comes in? I'd rather it waits say 10 secs then go off. the options in pocket toolman do not seem to work. I need the screen on a bit because often I switch to speaker straight away.
When I plug the charger in the TG01 the battery will charge up to 100%. The charging process will then stop (orange light turns off and never goes on again).
If my backlight or wifi is turned on, or anything else is running, the battery will start draining back down, but the charging process will not re-start. The battery will display 100% full as it might somehow detect the charger is plugged-in (?).
When I start using it, although the battery might have drained down to 40%, it will show 100% then suddenly jump to show the actual battery level.
I used to charge it overnight with backlight at full level and it would go from 100% to 0% after using it for a minute or two in the morning. I couldn't turn the device back on, even with charger plugged back in because the battery was so empty.
The trick is to turn off the backlight / wifi when it's done charging, or if you charge overnight, turn it completely off so it doesn't drain the battery when it's done charging.
hope this helps

This is not true. When the battery charges up fully, the orange charging light is extinguished to let you know it has finished charging, however the battery is still supplied with power to keep it fully charged. I know this because I use GPS alot on the phone and when it's fully charged using the car charger, it will still be 100%.
Try hard resetting your phone too. If it doesn't work, then there is something wrong with your phone!
Well it's bizzarre... the battery meter on the tg01 is certainly pretty dodgy.
with the flashing leds, what does anyone suggest? is there a way to change the led notifications back to default?
And regarding the screen going off immediately when a call comes in, it looks like there's no fix - similar threads still have no answer, unless anyone has more suggestions?
Update: I have done a full hard reset and a wm6.5 upgrade but the battery issues are still here. Has everyone who has had this issue taken it back to orange? It barely lasts 5 hours the battery.
Anything else at all to suggest???

I stand corrected.
While this was true before and had tested a few times with two different TG01 both with Orange UK stock ROM, I have retested it now and it does not happen anymore, but I have flashed a new ROM...
Apologies for the confusion.
Hi all
I was reading this thread and preferred to add my 'query' here rather than start a new one.
My TG01 has an original WM 6.5 rom minus the SPB Shell. I haven't experiences any negative experiences yet except for the fact that I have often heard about charging the battery for 8 hours etc and charging it with phone off which I always do except on few occasions I connect with USB cable to my pc /laptop...in my case I will charge my set with the toshiba wall charger that came with the set and orange LED will illuminate a few seconds after charger is plugged-in..from there onwards the orange LED will stay illuminated for maximum 3 to 4 hours and then will turn-off. I am not having any battery problems except for the usual battery drain depending on usage and apps but nothing unusual.
I'd like to know if this is normal? Is anybody else experiencing this? Not charging more than 3 to 4 hours (orange LED turning off after 3 to 4 hours).
I would appreciate some help on this 'doubt'
Thanks
I think it's problem with driver and charging akku. I have custom rom with 6.5.5
and when i charge my akku when it is on 20 % after 20-30 min shows me that 90 % full... After 1 1/2 hour akku full charged.

Well. it's not the solution, but this procedure can be a useful roundabout to access to wifi, or allow you to take a vital picture when you really need it and your battery is under 20% charge.
Imagine that you must send urgently a picture and you can't do it because someone from Toshiba decided this stupid limitation when you are at the end of the battery life.. following the maciek90's procedure, you can save this limitation and drain your battery up to the 0% if you want
Bravo maciek90! and thank you

guys, also another thing i learnt from my physics class is that putting a recharegable battery in the freezer for 1 hr, somehow give it longer battery! I tried this on my tg01 battery, it strangely worked , or it was all in my mind!
you've gotta make sure the battery isnt wet from condensation when you put itback in the phone! my battery last slightly longer. i dont do it often, only once every now and again... try at your own risk!

I definitely think it is either level measuring circuit problem or battery driver itself - not too big power consumption.
I can repeat without any problems situation where battery level suddenly decreases about 20-30% . I noticed it only during internet operations via GSM so utilizing radio. Why , I do not know . How to fix it ? I do not know yet but it is enough to restart system so that battery indicator start to show correct value - until next failure .
I thought when bad indication occures it would be enough to stop-start baterry driver using way You described. It does not work. Stopping driver cause battery indicator shows unknown level. Starting driver not fix it. Battery indicator still shown unknown value. Only restart fix it. It should not behave this way.
Maybe problem is not in driver but top bar of today screen when battery indicator exists, should have any kind of reset too?
BTH. What software is responsible for displaying battery indicator ?
Regards
fxdjacentyfxd
Today morning next described previously error concerned with GSM radio.
I had GSM radio switched off in the night and phone in sleep mode.
Morning, when I set phone to operational mode , battery indicator showed 50% - the same as yesterday evening.
When I switched GSM radio on, battery indicator suddenly showed 30% and none phone operation could change it. Only system restart caused battery indicator started to show correct value again - 50%

yes! i am not the only one! recently i got a data plan for my tg01. when i use the data connection for 1-2 minutes, the battery drops 10% and it will stay at its false value until i soft reset. i thought that the problem was with the rom that i was using but i guess im wrong. what ROM are you on? it is very annoying and i have to constantly reset my phone. i have done some test, and if i keep using it, on data, the battery could conpletely go dead like when it is out of power, then when i power back in it is back to its true value. any solutions?!
I have found so many guides on how to calibrate battery best. This one: http://forum.xda-developers.com/showpost.php?p=15450518&postcount=3 Or this one: http://theultralinx.com/2011/07/calibrate-androids-battery.html
Or: just charge until full, wipe batterystats and just let it run out of power, then recharge to full again (that is the easiest one). So would the last one be enough, or do you have to do it the complicated way to get best results?
Also when draining the battery until the phone shuts down (after deleting stats), should it be used normal or can I just run some applications to use up battery fast?
what i used to do was:
charge to full once,
unplug, (and you will see sometimes it goes back to 99%),
plug again for a few minutes,
unplug,
go to recovery and wipe battery stat.
then reboot and use the phone NORMALLY until it shuts off (set the brightness to highest for next step).
BOOT straight into recovery and leave the phone until it dies again because there will still be some juice left.
while off, charge it,
when it gets to 100% while off, unplug,
then plug it again for a few minutes,
then boot up normally.

Ive heard you should never "try" to over charging it by unplugging and plugging back in.
There are a lot of rumors and myths about battery calibration (and a lot of threads on this forum and copy-pastes on other blogs).
Personally I don't believe in long rituals with precise times and percents. Battery has build in controller, that can't be wiped. And Android has battery history file, that can be erased (butdoes it have any sense?).
Please, post link to authoritative source of information about battery calibration, if anyone has it.
Use the phone till its out, power it up via download mode to really drain every last drop. Charge it with the official charger while its off, once charging is full power on the phone let it boot properly and resume to charge maybe for 5mins then your done. Battery stats bin = totaly myth.

i hear you and i was reluctant to do that as well. but since new Li-Ion batteries have some sort of "overcharge protection" mechanism on them,
the batteries will stop taking in current automatically once they reach maximum mAh (not the battery stat maximum, the battery itself).
dangers related to charging are incompatible chargers, screwed up wall sockets, surges, etc. Know that companies nowadays keep saying "USE ONLY <company> COMPATIBLE CHARGERS"
because these chargers/cables also have this tech where current just stops once it's full.
well the "theory" was that since the battery stats is kernel related and gives battery "readings", when the number gets < 15, it will give out the warning to charge, then when the number gets to 0, it shuts off the system. This may happen but the battery MAY still have some power left in it, it's just the battery stats that says "hey, i see it zero, turn us off".
This scenario may happen to a screwed up battery stat reading, which is solved by wiping it's top charge number (1650) and the bottom charge number (0). the next boot will create a new
source file for the battery stat, containing no data then upon boot complete, the system will record the current battery level as top charge number to the battery stat. when it drains out, that
will be the new bottom charge number.
i do not have a wikipedia or engagdet source but Team Whiskey (a well known dev/mod team for Vibrant) of the Samsung Vibrant forum here in XDA explained it themselves.
Thanks for this thread. Really useful!

Hi,
I have been facing these two weird issues:
1. Sudden drop in battery percentage: I have found that this occurs only when i reboot my phone (not every time though). So when the phone restarts, the battery is down by 20-30% or sometimes even more. And its not a one time issue. I have seen it happen at least 3-4 times in the last 5 months.
2. Sometimes when I am not charging the phone, the battery % keeps increasing slowly. This has been happening lately since the time I have rooted and flashed my phone. 2-3 occurrences that i know. I don't recall seeing this when I was on stock. Just this morning I plugged my phone off the charger at 52% and I left for work. And right now at this moment when I am writing this, the phone is at 58% charge!!
Just FYI.. I calibrate the battery every time I flash a new ROM.
Thanks,
Sam

I think that Entropy can answer this better but I'll still give a try.
[Q] Why these sudden battery level drops after reboot?
[A] The sudden battery drops is a known 'issue'. It's not a bug, it's the way the fuel gauges are designed for i777.
[Q] How to avoid these sudden battery level drops?
[A] Try not to reboot while it's on battery if the battery level is <50%. In that case, if you need to, make sure that the phone is plugged in for charging and then do the reboot. That should prevent those random battery level drops.
[Q] Will using battery calibration apps help?
[A] No, the way the i777 fuel gauges are designed, there is no need of battery calibration apps. The best way to get accurate battery level readings is to allow the battery to go through full 100%->0% battery discharge cycles for atleast 2-3 times. After each full discharge remove the battery, keep it out for a minute or two and reinsert, recharge the phone.
PS: The weird battery charges that violate E=MC^2 law might have to do with your battery not having been through proper discharge cycles (and thus not having been properly calibrated) after flashing a new ROM.
@Mod These questions are asked many times, how about adding them to FAQs (not sure if that will help though )
@Entropy Please review this post.
Pretty close.
Calibration does nothing on our device - the fuel gauge is designed so that it will always converge towards truth instead of diverging. Also, the "wipe battery stats" method of "calibration" has been proven to do NOTHING on ANY device whatsoever - https://plus.google.com/105051985738280261832/posts/FV3LVtdVxPT - The "charge battery to full" and "discharge/recharge" battery are valid tactics on some devices, but NOT any Galaxy S or S II device (maybe the ****rocket and T989, but not the I9100 or I777.) - There's a slight chance this may change with ICS on the I9100/I777 but not likely.
The advantage of this is that it never needs funky calibration cycles other than "just wait"
The disadvantage is that the gauge will get thrown off in a few limited corner cases - and the "two" issues described are one widely documented one. The gauge gets confused and falseley reports low by heavily battery load immediately following a reset, and takes a few hours to converge back to normality (during which the estimate creeps upward, because it was lower than reality initially).
And yeah this should probably be in the FAQ. I'll work on submitting it this weekend.
Thanks guys..
So looks like the sudden battery drop issue can only be prevented but not fixed!

It's pretty much the characteristics of putting a battery under load and using voltage to dictate battery level. when you draw a lot of current from a battery you'll usually see the voltage level drop, more so as the battery is discharged. Booting up the phone consumes quite a bit of power, substantially more than the device at idle. So upon start up the device reads the voltage level to dictate battery level. Since the device is under a relatively high power draw, it sees a lower voltage than would be at idle. It in return thinks the battery is lower than it actually is, or would read under idle load. the battery level will actually creep back up slowly because it will read a higher voltage, than it did upon start up.
The only way i could think of to get a more accurate reading would be to delay the initial voltage reading/recording upon start up, or to use the last voltage reading to help dictate the battery level. But i have no idea if that's even possible, or if it would conflict with some sort of other operation.
I just don't get it!!!!!!!
I was playing multiplayer in bombsquad today morning wid my friend .My battery was @ 86% at that time
suddenly my battery came down to 15% then in the other moment it went to0% and mt phone got shut down. I plugged my phone in charge through the power bank and rebooted it and I saw my phone was @52 % I started using my phone and it again suddenly sut down this time without even a battery low message
it's been happening regularly wid my phone since then.
What could be the reason? And what can I do to make it right?

This is the wrong forum. Even though the thread is about a problem similar to yours, we don't know anything about your phone.
If you have a removable battery, you might try purchasing a new battery, but that's just a guess.
The forums for you phone are here.
First, a few things:
I'm well aware there are several other threads about this already, so before you go -"Arrhh!... not another one!". Read this: We need a more complete guide with more facts about what's going on, and details on how to recover from it.
Questions and new threads that involves bricking, red led of death, battery failures and so on, are very common. I felt it's time for this thread to spring to life.
If you have additional information, tips and/or corrections, please do post.
I'll complete/edit this post accordingly.
With that out of the system, let's go on.
The red LED blinking rapidly three times, from here on called FRLoD (Flasing Red LED of "Death")
The X10 have now reached an age, where battery failures, and strange behaviour as a result, are fairly common. Specially if one got the device early on. So if you're reading this hoping to get your device back into life, the whole thing might be a result of just that: Battery is failing due to wear and/or age.
Questions:
What's does the FRLoD mean?
Simple answer: The battery has "run out of juice".
It's so empty, the device cannot startup at all. Not even to show the offline charging screen. Any attempts to restart the device will only be followed by the FRLoD again.
Sometimes, one can let the device rest for a while, and restart can be achieved, but the luck soon runs out as the device simply shuts off during the startup procedure, and back into FRLoD mode.
If it can't show the offline charging screen, does it mean the device can't charge?
No. It will charge, it just can't show you that.
In fact, if you have the charger connected, it does receive a charge, but it will take some time before the battery has charged to a level where it's safe to show the offline charging screen again.
So what you might want to try, is to let the device charge blindly for a while.
It will take from a few minutes to a few hours, before the device kicks back to life and shows the charging screen. How long it takes depends how badly the battery where drained.
Yes it's quite possible to drain the battery beyond the "empty level".
I had my charger/USB connected all the time while in recovery/flash mode, shouldn't that keep the device alive even if the battery fails?
No.
When the device is in flash/recovery mode, it won't charge at all, even if connected to a power source. It will slowly deplete/discharge the battery, and it will run out of juice if one sits for too long in either mode. So when the battery drains/fails, the flash or recovery mode will fail with it.
This is why it's so important that the battery is fully charged before one attempts recovery/flashing the device.
Why it is designed like this, is beyond my knowledge. I belive it's the same with most, if not all, Android devices.
It seems the battery won't charge "blindly" at all. What can I do?
Charge the battery externally, with a proper Lithium Polymer Charger. One can even use an universal 3.6 volt Lithium Ion charger, as the charging method of either is basically the same.
Be careful: Never ever leave a lithium polymer battery charging externally unattendend. It can be dangerous. Keep an eye on the temperature. It should never exceed 50 degrees Celcius / 122 degrees Farenheit. If it does, disconnect immediately.
If charging externally is out of the question, you need to replace the battery with a fully/partially charged one.
There is also a rather "ugly" trick one can attempt:
Only perform this as a last resort. It's very dangerous, but might be worth it if everything else fails, including getting a new battery.
Pull out and shortly charge the lithium Polymer battery with an ordinary 9 volt battery.
Connect the positive terminal to the other positive terminal, and the negative terminal to the other negative terminal. Use a short pair of wires for this. Only charge it for a few seconds at a time, and never let the batteries temperature go beyond 50 degrees Celcius / 122 degrees Farenheit. (slightly warmer than your hand)
This will briefly kickstart the battery to life, so one can start charging it normally in the device.
I can't make the battery last long enough for this flash to succeed. Now what?
Simple: Get a new battery.
A fresh battery should be able to keep the flash/recovery mode active for several hours / a whole day.
What are the signs of a failing battery?
Here's a list:
Symptom: Device suddenly shuts of when used, even when battery had several percent left.
Reason: Battery can't take high load very well. the voltage dipped so quickly, the battery indicator didn't have time to update.
Symptom: The device only lasts for a few hours/minutes, before it needs charging again.
Reason: Old age. The battery has lost so much capacity, it's running on the last breath.
Symptom: Charging is incredibly fast.
Reason: Battery has, due to old age, lost too much capacity. Low capacity = Reaches full cell voltage quickly.
Symptom: Device shuts off, and it need resting before it can restart again.
Reason: Again. Old age makes the battery unable to keep the voltage at a good level. Resting lets the battery slowly build up the voltage level. Internal resistance is the "bad guy" here.
Symptom: Battery gets warm, even hot, while charging.
Reason: The battery is about to run out of charging cycles, and the charge is lost in form of heat.
Most, or all, of these symptoms are followed by the FRLoD, either temporary or permanently, depending on how bad the battery condition is.
I've charged/replaced the battery, and are having trouble with starting up. Earlier flash failed. Now what?
Don't worry. It's pretty darn hard to truly brick this device. Even if the screen remains black, there's still hope.
Once that the battery issue has been dealt with, you can move on:
Download the latest Flashtool and the proper global firmware (FTF-file) for your device from here:
http://forum.xda-developers.com/showthread.php?t=920746&highlight=flashtool
1: Extract/Install the Flashtool to a folder of your liking.
2: Copy the ftf-file to the "firmware" folder in the Flashtool folder you just created above.
3: Start Flashtool. Click the Bolt icon (flash). A Window appear. There, choose "flashmode". Cllick OK.
4: A new window appears. In the list on the left, choose the Generic firmware you downloaded and copied into the "firmware" folder. Should have a similar name as the file itself. (Or manually open the ftf-file from the "..." icon on the top right.)
5: Hit "OK. Follow the instructions you get on the screen:
1 - Unplug the device.
2 - Power off the device. (Unplug and replug the battery to be sure it really off, and not stuck in black screen)
3 - Press the "back" putton, and hold it down while performing the next task.
4 - Plug the device into the computers USB.​Forced flashing should now start.
Once done, the device should be back in it's original state, and you can now start over. Rooting, boot loader unlocking, etc...
Good luck.
I have i717 AT&T updated stock ICS rooted. I set the device in Power Saving mode to kick in at 50% battery life. Once it hits the 50% battery life mark it displays a notification window saying "Battery level below 50%. Power saving will run. Continue?" It seems this notification pops up almost every time I bring the phone out of rest mode (clicking power button to turn on the screen's lockscreen). It alerts me many times.
It's incredibly annoying when my phone alarm wakes me up in the morning and I'm reaching over to try to slide my finger over the screen to shut off the alarm, but it won't do anything because the damn power saving mode notification window is up and waiting for me to press OK or CANCEL.
Can I disable this notification? I can't find the area to make this setting.
I also looked at installed apps and don't see anything that resembles Power Saving Mode to see if there are any settings I can make through ROMToolbox.
Is this something I can try to disable through Tasker?
Can anyone please advise?
Why is your battery below half first thing in the morning?
You could charge it overnight then the battery will be full when your alarm goes off.
Otherwise to turn off that notification will take some editing of the rom.
That notification is there because power saving mode under clocks the cpu amongst other things that sacrifice performance for battery life... if when you want to unlock the device and run it full speed for just a couple minutes you hit cancel on that notification... or ok to run at the throttled specs of power saving mode.
I played around with power saving mode when I first got the note and noticed that any power saved by the throttling was wasted by me waiting on it with the screen on lol . So I just bought a second battery and external charger.
I am of the old school of "rechargeable batteries" where I let the battery drain to near 100% before charging again, and when I have it plugged in for charging I let it get 100% before disconnecting. I don't know if the batteries today don't have the problem of losing its lifespan due to incomplete charge sessions.
I get about 48hrs between charges with the workload I put on the device...NOT a phone gamer or constant "feelings" updater on facebook.
Studacris (I feel odd saying that) - mind if I pass an issue by you for your opinion?

I'm reply #7 - I thought I found the issue of my default ringtone/notification sound resetting to default all the time...but it JUST happened again.
Advise?
The chemistry in batteries nowadays is much improved as well as software for charging:
True a battery does have a finite amount of charge cycles, however a charge cycle doesn't count add each time it's plugged in, it's each time a full 100% charge and drain have occurred:
drain halfway, charge full, drain half, charge= 1 cycle and so forth.
Furthermore overcharging isn't possible. android stops charging at full and the lets the battery sip on 1% for a while then starts charging eventually once needed.
And with such a low cost for a replacement battery it really isn't much to worry about.
