Hi!
Question: When an XDA is placed in the cradle (w/ charging) or car mount it starts charging and the LED goes orange. After the battery is full the LED turns green. So far so good. What actually happens in the device when it decides it is full? Is the battery "disconnected" by some means? I mean if the device is working (navigation) is it drawing power from the battery which in turn gets instantly replaced from the charger or is the battery left alone and the device just draws power from the charger?
I was wondering if it is possible to turn off "charging" by some little tool or hack. Reason is that I use my XDA for navigation and I hate the feeling of allowing memory effect when I put the device in at 70% battery power, drive somewhere, take it out at 100% and then put it back in at 90% for the way home. My navikit unfortunately does not allow disabling charging, because there is only one button that powers GPS mouse, charging and speaker.
I know that playing with this is potentially dangerous, but I am just wondering. If there is no way I think I should take the navikit to some who can solder...
Any ideas?
Li-ion batteries don't suffer from the lazy battery or memory effect like Ni-Cd or Ni-Mh batteries do. I would surmise that the charging circuitry is deactivated once another primary power source is detected. According to battery-university.com , Li-ion batteries used in cell phone chargers don't enter the so-called "trickle charge" mode as Ni-Cd and Ni-MH batteries do.

I'd really love to believe this. But check out this. When I run low on power I usually "discharge" as good as possible before recharging. Like disabling auto-off for device and backlight and giving the CPU some stupid load. At some point the device just gives up and turns off. That should mean "battery empty", right. Turning it back on after this gives me only a minute or a few seconds of idle runtime. Battery empty, one thinks. One day when I considered the battery discharged I exited a program which locked the device completely. The backlight was on but there was absolutely no reaction to ANY button or digitizer tap. Not even the power button worked. Fine I thought, perfect battery drain mode. The XDA ran for another 45mins with backlight blazing. 45 minutes of backlight. That's 6 hours of standby or 30mins of usage.
So maybe there is a memory effect which is not quite as high. Or maybe the XDA circuitry is designed to be so "secure" (as not allowed complete drain) by default.
Whatever. Thanks for your input and time. Will check out the link now.

no it's not memory it's because the cpu and everything apart from the screen is off
but the tool reporting the % calc with the current being used when it's running and thats with cpu gsm and everything on
also all li-ion die after about 2 years and in the end of their life they start to act pretty funny
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

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 seen lots of threads about people complaining about very poor battery life after flashing roms. Sometimes battery charges to 100% quickly and discharges very quickly.
So, these are the solutions. These solutions are IN ORDER. If the first one has no effect, then try the next one. If the second one doesn't work, then try the third one.
Now-
1) Try reflashing your ROM.
2) If reflashing your current ROM doesn't work, that probably means the ROM itself has poor battery life and you should change it. Stock ROM's have the best battery life.
3) If you are on stock ROM and still having problems, switch off your phone, take off the back cover and remove the battery. If the battery is swollen or the shaped weirdly, this means your battery is dead and almost useless. You need to buy a new one.
I recommend buying only stock batteries manufactured by Samsung because other batteries can be fake, incompatible, or just used batteries sold to you. Don't buy anything else unless you're absolutely sure of what you're doing.
Hopefully I helped.

General tips for saving your battery-
1) Switch off mobile data whenever you're not using the internet.
2) Change your wifi sleep policy. This can be done by going to wifi settings, pressing menu button and then select advanced.
You can change your sleep policy so that your wifi sleeps when the screen is off.
3) Decrease your brightness! Your screen is responsible for most of the battery drain. Increase your brightness only when you are in bright sunlight or when you're watching videos etc.
4) Switch off GPS. Keeping it on all the time also drains a lot of battery.
5) There is an app called 'Greenify' which hibernates the apps running in the background. This app has increased my battery life. Here a link https://play.google.com/store/apps/...e=google&utm_medium=organic&utm_term=greenify
6) Don't charge your phone when it's at 70%. Wait till it is between 20-30% and then charge it continuously till it reaches 100%.
7) Let your battery completely discharge once every month.
8) Don't use task killers. They use more battery life than they save.
9) NEVER charge your phone overnight. Your phone takes only about 4 hours to charge. Overcharging reduces your battery life
10) If you use a Bluetooth headset, switch off Bluetooth whenever not in use.
11) Using setCPU profiles. This is one of the most effective ways of saving battery. You all know about overclocking, but do you know about underclocking or undervolting? Using profiles, You decrease the clock speed of your CPU when certain conditions are met. These profiles can be on the basis of time, screen off/on, battery etc. So when my screen is off, it automatically reduces the clockspeed which saves battery

Using these tips, I have gotten almost 2 days of battery life on stock Roms and a whole day of battery life on custom roms like CM10.1 and CM7
If you have your own battery saving tips, please share and help expand this list.

Are you sure about these? Because I've read that phones only take how much ever charge that they need, so charging overnight isn't a problem. And i've also heard that letting the battery charge fall below 40% actually reduces the life over time.

Yes, I am sure and it is something I have verified.
Overcharging kills the battery.
I saw a video once of an evo 3d. The battery almost completely died after it was charged for 3 days
And you should always charge only when your battery is low.
This will ensure longer battery life

Normally, when the battery is fully charged, the chip that controls the charging process reduce the current exponentially to 0: this avoid the overcharging.
I think all smartphones have the charging chip control integrated (an USB cable is simply a power source, not a battery charger), so I hope we can leave the phones on charge all the night without any problem. I do that always and never had problems.

Quoting Dianne Hacborn(Android Framework Engineer):
"Today's myth debunking:
"The battery indicator in the status/notification bar is a reflection of the batterystats.bin file in the data/system/directory."
No, it does not.
This file is used to maintain, across reboots, low-level data about the kinds of operations the device and your apps are doing between battery changes. That is, it is solely used to compute the blame for battery usage shown in the "Battery Use" UI in settings.
That is, it has deeply significant things like "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."
It has no impact on the current battery level shown to you.
It has no impact on your battery life.
Deleting it is not going to do anything to make your more device more fantastic and wonderful... well, unless you have some deep hatred for seeing anything shown in the battery usage UI. And anyway, it is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point), so this would be a much easier way to make it go away."
Its just a myth mate..
And also, it's a myth that you should let ur phone charge reach 10% or get fully discharged before charging. This actually leads to decrease in the battery life over time.

Think of your battery as a person working out and charging is like taking rest. If the person's ability is to do 100 reps yet he takes rest after only 60 reps and keeps doing that continuously, he won't be able to do 100 reps after a few weeks!
Look at the logic mate.

This! Anything about wiping battery stats is not a myth anymore, so please stop misleading people,
Also "6) Don't charge your phone when it's at 40%. Wait till is below 10% and then charge it continuously till it reaches 100%."
Not true! Charging your battery around 50% is the most efficient way to keep lithium battery alive longer. A discharge once a month is also recommended.
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.
let me say one thing first: i don't want to discuss if resetting the battery status database helps in any way to prolong the battery life of a phone or such, i have a different issue with the battery management under android:
i have taken the guts out of an AN1 Smart Watch and used them as a tiny touch panel in an appliance. in order for it to run without a battery i have connected a little voltage regulator that converts DC12V to DC4V and feeds it right into the + and - Pin of the battery contacts. This way i can start and run the device wihtout any battery in it, which otherwise is not possible when trying to run it from USB power, even though i haven't seen the device pull more than about 300mA at most.
the device turns on and runs just fine, but what's bothering me is, that the battery charge indicator is counting downwards even though the voltage stays constant and obviously notthing really is being discharged since there is no battery.
i don't want to re-insert the battery and run from usb power as the battery will certainly fail within only a few years and i would really like the whole thing to run a bit longer than that.
is there any way i can re-set the battery countdown or disable it entirely? if disabling the simulated drain is not possible, resetting it should be possible while the device is running. i don't want to reboot the thing every day just to reset the battery stats or anything like that.
hope somebody can help me out here.
i currently have the AN1 running to see what's going to happen when it reaches 0% ..

Click to expand...
Click to collapse
so here is what happened... the battery was constantly "discharged" until it reached 15%. it then showed the "please connect your charger" message but stopped dropping the battery level.
would still be nice though have a possibility to prevent this message from appearing. even though it is not as critical anymore, as the device will be running 24/7, so unless there is a power outage, this message only appears once and that's it.
i have attached a screenshot of the battery statistics with a power supply connected in place of a battery..
