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
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'm having this problem with my i777.
Sometimes when I reboot the phone the battery charge drops enormously, like 30% or so. For example, I will be doing things with the phone, the charge will be at something like 60% then reboot and right after reboot it says charge is 30% which doesn't make much sense.
this happens with the stock battery but the effects seems to be more pronouced with some batteries I bought on ebay.
Anyone has any idea what's going on?
what rom are you running on?

Normal behavior of our fuel gauge hardware - high load (boot process) immediately after a reset confuses it and makes it report low. Effect is much more pronounced at lower states of charge.

That's exactly right. Tends to happen more on lower states of charge.
Does this mean that the charge indicator will go up after the reboot? Or maybe it will take longer to drop and the effective battery life will be the same.
Yes when this happens to me my bettery either dies extremely slow or my percent just goes up..

I see this too. I will be at ~40%, reboot and see 10%. Come back after a while to 12%, and it stays on 12% with like an hours worth of heavy use before going lower. If I look at the battery usage, it trends down, then drops, but stays level, then about when the trend would have been it starts dropping again.
I thought I just needed to calibrate the battery, as I just flashed a new ROM. But, it keeps doing this after a week, and several charge cycles.
Guess I'm relieved to see this weird behavior is not indicative of a problem.

Correct - because the gauge thinks the battery is lower than it actually is when this happens.
Attached a screenshot of the battery use with the big drop in effect.
I particularly think this is a bug and Samsung should fix this behavior.
It can't be changed without hardware alterations.
As with anything in engineering, there are tradeoffs. The positive aspect of this fuel gauge design is that it does not require ANY calibration. No wiping battery stats, no "always flash firmware at 100%" - none of that.
The negative is that in a few corner cases, it gets thrown off temporarily. This is basically the only known one.
Ive noticed this as well with both Stock and ICScreweD. I just try to reboot as least as possible.

If you reboot at higher states of charge, OR reboot when on external power, you should not see this issue.
I just had this same problem lol. I was at 42% and when I rebooted my phone it dropped to 23%....This was a few hours after the OTA update to 2.3.6.
I had the same problem also.
-Battery would not charge to 100% ( it would charge between 97% -98%)
-Battery would drop 20% or 30% percent (when reboot).
I tried to recharge many times and cycles the battey but nothing would work.
I tried changing kernal, modem and roms . Nothing would work.
I actually thought i messed my phone up.
So i tried something that work for me.
1) i would let the battery drain till it was completely dead!
2) I would take battery out for 5 minutes.
3) put battery in and charge with phone OFF till it reaches 100%.
4) unplug charger from phone and take battery out and wait 5 minutes.
5) put battery back in and plug charger up and wait till phone marks 100% again ( This time the wait was longer to get to 100%).
6) i repeated step 5 untill finally the phone would mark 100% faster
7) unplug phone and then wait to see the battery status ( if your phone mark 99%) plug charger to phone and let it charge till it reaches 100% again. once it reach 100% reboot and repeat step 7 untill you reboot and it would show 100%.
not sure if this might work for anyone else but it did work for me. battery would charge to 100% and i don't have my phone drop 20-30 percent after reboot.
If it drops 20-30% on a reboot when the battery is near full, you may have a defective battery.
I've only seen major drops on reboot when the battery is low to begin with, never when at higher states of charge.
Doing a full discharge on Li-ion batteries puts a huge stress on it and greatly decreases the life of the battery. To get the longest life out of a battery, you want to generally stay in the medium range of charge (Don't over charge it, and don't discharge it too much). Cars like the Chevy Volt employ these techniques to encourage a longer battery life, however with phones, you get users that think discharging the battery all the way solves problems. If you want to see the true battery life that the fuel gauge averages from, press *#0228# in your dialer and check the battery voltage. Full is around 4.1v and discharged I believe is around 3.5v or so. (maybe 3.3? not sure)
3) put battery in and charge with phone OFF till it reaches 100%. <-- is probably what fixed it, and why I switch batteries instead of charging on my phone because the charger is able to control the current and voltage better than with a slight load on it (with phone on)
I'm sure that that user cut off at least 5% of his overall battery life with overcharging it like that though...
Same issues here pending the ROM I'm using.
4.2 volts is the upper limit for li-ion - and actually, it hits that at around 95% charge.
The method for charging Li-Ion:
Charge with a current limit initially - on our devices this is 650 mA.
Once you hit 4.2 volts, do NOT go above this - maintain voltage at 4.2 volts or lower regardless of current
Once current drops to around C/10 (on our devices, this is about 160 mA), shut off charging completely.
The phone's charge controller does this all automatically for you.
There's usually a timer/averaging filters in the final stages of charge termination - which is why "bump charging" can push a little extra into the battery - but this will lead to degradation in battery total capacity.
As somewhat of an extra trivia on Li-ion batteries, Motorola has apparently managed to get batteries that have nominal voltage at 3.8v and max charged voltage is around 4.3v as opposed to 4.2v.

Hi everybody
I've got a major battery issue with my three year old Nexus 10.
The battery indicator shows something around 75%, drops to 0 in a split second, switches in energy saving mode (notification and navigation bar are turning red) while it shuts down.
To verify I made an Automate Flow saves the battery charge every second to a text file. Result:
Code:
82,82,82,81,81,81,81,[...],73,73,73,73,0,0,0,0,0 EOF
Okay, it thought to myself, after three years the battery is broken. So I bought a replacement battery (Samsung original) and replaced it - but nothing changed.
To clear all old stats (and running Android 6.0.1) I wiped everything TWRP offered and installed CM13 - but nothing changed.
Now my only guess is, that there's some EPROM (or other memory hardware) that stores battery stats.
Can you, dear forum, help me fixing that issue?
No one?
Has anyone of you guys changed the manta battery, yet?
Same thing after OTA upgrade in D6563
I'm facing the same problem here with my d6563, after the MM OTA update i started to face quick vertical battery drop, but we're not the only ones, some users are reporting this issue in a lot of devices, some of them after update, some others after rooting, some of them just after some apps update, and the thing is that nothing seems to work, some users claim to have solved the issue, but they are just talking to fast, because the problem comes back the same day, they just think taht the battery data is accurate but then the drop accurs, si, i'm starting a new thread listing all the solutions tghat senior members have recomended and failed in order to track this problem to his roots once in for all, it's been happening since kitkat at y has come worse since marshmallow
keep in touch to see what we can figure out about this.
Battery _stats_ issue
I had, ummm, similar issues with my TCL S720 (in less degree) and now with TCL M2U (TCL Meme da 3N M2U AKA Alcatel Flash+) phones.
TCL M2U has 3500mAh battery capacity.
After full charge it discharge normally to ~40%. Behind 40% it is discharged to 1% for a few minutes and shuts off!
If then I charge it again to 100% then it eats about its full capacity (~3500mAh) - checked with Keweisi USB Doctor and shows 100% charge, but discharges to 40% again.
On other firmware there is similar effect but for 30% level or 15% level, it depends on firmware.
I think that the battery is OK but the charge percentage display is wrong.
Another strange thing is when I see the charge level using Ampere app. It shows i.e. 50% battery level and 3.762V voltage on the battery. Then I plug it in charger. For a short time the voltage rises to 3.8V and more but the battery level is lowered to 45%! Also if I charge the phone from discharged state then the battery level is 1% for the long time, then it quickly raise to ~30% and then shows charge process normally (almost linear). The USB Doctor show the charge process smooth almost all time (from stronger current to weaker).
So I join to the 1st post question: where is the battery's _real_ voltage level data?
Hi. I am running my OnePlus 7t Pro with Lineage Recovery and LineagOS 19.1.
I had the battery exchanged with a new OnePlus battery. No after market crap. Before the exchange, the same LineageOS version die no show any of the problems.
Since then, my battery shows wired percentages. About 500-1000 mAh are used from 100% to 1% and for the rest of the battery runs on 1% for about 2000-2500 mAh. Sometimes the percentages jump down 10% in seconds. See attached images for reference.
What have I tried so far:
I have tried the usual calibration method 3 times so far, with no change to the problem.
1) draining the battery until phone switches off 2) Charging > 4 hours with phone off
3) Switching phone on, while still charging
4) Continue charging
This did not solve the problem.

Try fastboot flash boot twrp.img instead, if you want to install a new TWRP.
To delete the cache, why not start in recovery mode? Lineage 19 tends to install its own recovery, overwriting an existent TWRP. It looks different, but deleting the cache should also be possible in this recovery...

Sorry. Forget to mention. I used fastboot boot to use the twrp.zip installer. Using flash with twrp.img leads to the same result. Without lineage os being booted.
But does not look like the chance thing would solve my issues.

First enter recovery mode (Shut down phone, then start it with simultaneously pressing power and volume down. After starting release both buttons and you will enter recovery mode)
There`s a very simple menu, not to compare with TWRP. Maybe under the "Advanced" button you could find a wipe cache...
Nope. No such feature in Lineage recovery. And other idea for the battery problem?
From within Lineage recovery you should be able to install a TWRP (either placing it in the download folder before or mounting an attached USB drive) Then, you could try to clear the cache.
As for the 7t weekly Lineage updates are provided, this may also be an option...
Sorry no. Was running with the exact same Software smoothly. My besteht guess right now is a faulty replacment battery from oneplus
Thats the current state
The battery of the 7 pro has got a capacity of about 4000 mAh. A fully drained battery should require about 90 Minutes on a standard USB2 port to become fully charged. USB3 delivers 4.5 Watts, therefore about 50 Minutes. (Loading with phone turned off) If your new battery is fully charged in shorter Time, this is strong evidence of a faulty battery.
As the percentage values of your phone seem to be unreliable, you could take the battery voltages, which should be accessible in AccuBattery as a measure for the energy status. If the voltage values correspond to the load percentages, then it`s almost proven, it`s no software problem...
Roughly 2000 mAh of the 2700 mAh used with 1% of battery. Above 1% I had about 4,050 mV. With 1% I had also about 4,000 mV. Than it starts to drop with ongoing usage. Now I have 3,700. Somewhere below 3500 the phone switches off.

Edit. Wired behaviour obsereved.
1) let the phone dying, charged it to 100% in switched off state, wait until it shows 100%, switched it on and the OS shows 100%
2) let the phone dying, charged it overnight in switched off state. In the morning it shows 100%, switched it on, OS reports 86%, switch it off, system shows 86% and charges. I could repeat the process. Charge it up to 100%, boot OS. OS reports a different value. Repeated it for 86, 93, 94, 95, 96, 97, 99, 97, 97, 100%.
By now, I really think that the chip of the bettery reports nonsense.
Your battery voltage is about 0,2V too low. Therefore it switches off at 3,5 V (instead of 3,7) and a fully loaded System shows 86% (@ 4V, I assume)
The software interpretes those Voltages as a (wrong) charge state.
You have got an additional resistor in your power supply (maybe a bad cable or not fully engaged connector). The spikes in charge state occur surely under heavy load, where the voltage drops, as the resistance prohibits your battery from delivery of full juice. If power consumption is back to normal, then the voltage raises again and the charge state is back to "normal".
You will have to reopen the phone (yes, it`s a pain in the ass) and check the resistance between battery and mainboard...

Full battery is 4,300 mV. 79% is still 4,300 mV and 65% is still in this area 4270 mV (See screenshot).
I use Geekbench to drain the battery for the calibration process. When I put heavy load on the CPU/GPU (e.g. Geekbench 5) the voltage drops by a guesstimate of 200-300 mV and recovers a few seconds after I stopped the load.
Seems to be exactly the behaviour you are describing.
I'll report the result after opening up the phone...urgh. don't wanna do it.

Were are the good old times, when you could swap a battery within a minute?
Even Glued together, most of the phones are still dying, when submerged in water. So I cant´t see any real progress, except for the revenues of service stations...
The battery of my 6t is still ok, but I´m afraid the day where a change is necessary.

It feels so wrong to hit the phone with high temperatures to loosen the clue.

I have the same problem with a battery bought from repairoutlet uk, lineage os also.
But I thought it was a problem with the battery.
I hope you will keep us updated ..

I will. Just hard to get hands on a new OEM battery right now that not just has the OEM sticker, but is really original.
So guys. I have a new battery in. I'll keep you posted. After a first full charge, it seems that I have now the reversed problem already 100% for 60 minutes. Let's see after the first discharge/charge cycle
Glad to read your problem seems solved. The downside is, there are batteries sold as new and maybe "original", that are almost completly useless.
You may not expect the full lifetime and/or capacity when buying a third party battery, but I never encountered such a catastrophic specimen.
Especially with modern devices, where you can't just easily swap the battery within a minute, this is very painful.
What I've learned:
1. Buy only from credible sources, where you may get a refund, if you're not satisfied.
2. In any case, before attaching the backcover after a replacement, first check the battery status.
