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?!
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.
Got this device around a week ago and I'm finally daily driving it. I've noticed a big issue though... I can't charge the device past 80% when its turned on. It stops itself from charging it seems like. I have to turn off the phone completely, and plug it in when powered off to get it to 100%.
Is there a setting I have checked or something? maybe a Kernel Tweak I don't know about that could be causing this that I could change/reverse/modify?
Thanks!

Turn off optimized charging.
ohhhhhhh. Epic. Thanks
It's not a good idea to charge with screen on especially in high temperatures or in direct sunlight. You can cause hardware damage like this... auto thermal shutdown may not engage fast enough to save the device.
In general charging while using skews the charging curve, increases charging time and battery stress. These phones have a fixed heat sinking capacity which cases and glass screen protectors further compromise.
Constant operation with battery levels near 100% will impact battery longevity noticably.
Keep watch for any signs of case bulging. It indicates battery swelling/failure. Replace it immediately if this happens. Other signs of a battery failure are a sharp drop in capacity, erratic fast charging or failure of fast charging to engage. A swollen battery can destroy the display.
The risk of a thermal runaway event increases exponentially with a failed or degraded Li.
Replace them when their capacity falls below 80% of new to avoid a failure.

99.9% of the time I'm charging, the screen is off and I'm watching tv before bed. I'll unplug at 100% and go to bed. I also won't plug in until I'm under 15%.
I work in cell phone whole sale and repairs, so one thing I understand well is taking care of a device.
But, disabling that setting recommended above, it still stops charging at 75% entirely and never goes to 100 unless I turn it off entirely

If the screen is on it may not charge at all.
This is normal.
Cycling the battery like you do stresses it and will reduce its lifespan.
Li's like frequent mid range power cycling.
Not under 30% or over 80%
If it didn't use to behave like this the battery may have degraded. 1-2 years is a typical lifespan for a heavily used Li. Approximately 200 full charge cycles.
Replace when it degrades to less than 80% of its original capacity to avoid a failure.
This phone has only been out since January 2021, so its not a batter degrade issue. Plus, it was pulled brand new out of the box like this. You also didn't read what I said. I'm not using it while charging at all. Its sitting on a table next to me while I'm watching tv or gaming on my PC/Switch. I'll check it once in awhile to see battery percentage and it will stop at 75%, then discharge as if its not plugged in at all. I have to turn the phone OFF COMPLETELY to charge it to 100% once I get to 75%
I'm assuming software issue. when I had GSI roms on the phone, it worked fine.

Li batteries can fail at any time.
Symptoms; diminished battery capacity, erratic fast charging. Any signs of phone swelling, usually the rear cover is a battery failure in progress. Replace immediately.
If the phone is drawing more current than the charger and/or the power controller can supply, it will drain the battery.
It may be a software, firmware or hardware issue...
Check all settings, disable all power management. Enable fast charging (toggle on/off 3 times then leave on).
Clear system cache and do a hard reboot.
Return associated updated apps to their factory loads.
If you did any major firmware (OS) updates do a factory reset.
A defective/improper charger or cable; try known good Samsung charger/cable.
Defective C port PCB.
A failed mobo.
Time to send it in for service or replacement.

It's a standard OnePlus feature at work.
Hi everyone,
it seems that battery issues on these devices are quite common, but I wasn't able to find out much about my observations, yet.
I recently got this model cheap in stock condition and decided to revive it. It's running /e/ OS currently, but the displayed battery percentages are extremely erratic.
When fully charged, the battery drains very consistently for 15-20% per day while in idle. However, if rebooted at any time, the phone immediately shows a completely drained battery at 2-4%. It will stay that way until fully charged again and despite the displayed percentages, the battery-app (correctly?) calculates multiple hours of charge remaining.
It does seem like some kind of software issue, since the phone does not turn off or refuse being charged like other users have mentioned and the battery still does supply hours/days of power.
On the other hand, the issue was apparently also present on the stock Android, so it would have to be either firmware- oder hardware-related?
Has anybody experienced something similar with this or any other device and is there anything I can try to fix this?
Or is the battery itself malfunctioning and needs to be replaced? If yes, are there any brands or replacement models to recommend for this phone?

its the battery that needs to be replaced. I had the same issues with my moto z (xt1650), the battery replacement fixed it all. the battery life is now incredibly longer than before and i didn't experienced any suddent drain at reboot.
all that for just 13,99$

Hi guys, My device keeps turning off randomly - I haven't found any correlation between battery percentage and turning off nor what app I am using. Happens at 80% as well as at 35%. It just straight turn off, no rebooting etc.
I haven't experienced this behavior while charging though. Also I experienced few times that even when the battery was at like 40 % and phone turns off on the turning off display when there is a sign turning off and litle circle under it, the battery indicator in status bar suddenly turns red as it's empty. Phone turns off and while I plug in the charger it shows correct percentage - e.g. 40 % again.
about phone:
This started cca 2-3 weeks after display change, I thought there might be an issue with connectors badly plugged in or something- checked and everything was ok.
Phone was running on custom ROM Pixel experience (android 10) for over half a year without any issue so I thought there might occur a software issue- I flashed new ROM - Lineage 18.1 (android 11), sadly it didn't solve the issue.
I also did a baterry scan with app Battery Recover 2021 with results: Low 2 %, inactive 3 %, healthy 95 % so the battery is also not an issue.
Only thing I found that is not 100% working is power button, even when I take the back housing off. It's probably worn out and I gotta press it few times from random angle/press with force to do what it's supposed to do.
Can this be the issue? Can this piece of hardware cause random shutting off? Any ideas?
Thanks guys
How old is the battery? It's a prime suspect.
They're cheap enough, throw a new one in.
Replace the power switch if possible as you know it's bad.
Otherwise if it's not gotten wet or dropped and the connectors are all ok, barring the above former causes it's likely a C port pcb or mobo failure.
Do some Google searches for this series of phones to see if others have had similar issues and the cause. Use XDA in the search to find results here.
the battery is original, so 4 years old? It last 1-2 days prior this turning off issue has happened so I think it's capacity is fine, nevertheless I still ordered a new one and I'll give it a try since phone is not turning off while being charged.

Degraded Li's can fail just like that.
A degraded Li is defined as one that has lost 80% or more of its original capacity. That's when they should be replaced to prevent a failure which can damage other components.
A swollen Li is a failure.

thanks man, it was the battery. I replaced it and phone works, no signs of random turning off.
Yeah batterys are usually the thing wrong
