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 ?

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've had my Titan for nearly 5 months now. I am hoping Titan's battery isn't that crap as I think. However, since last 1 week what I've seen is my LED goes green to indicate that my phone is charged. It shows 100% in battery saver menu. However, if I restart my phone while it's plugged in the charger even after green LED, then after the reboot my battery is down to 89-91% mark. Either the battery calibration has gone wonky or the LED doesn't recognise the real battery levels.
It would really help if anyone who charges their phone during the coming week, could restart their phone while plugged in as soon as you see green LED and then see if anything changes in your battery stats?
I've noticed my phone does last an hour or two longer if I charge after this reboot till it's 100%. It could well be a placebo effect for me. But might help if others see the same too.

The calibration is a little wacked. Here is my example - i charge it for 5 hours and it says 100%... but it only lasts about 7 hours and i can tell throughout the day that it drains faster. If i charge it for 8 i get closer to 13 with heavy web and game use. At 5 hours it turns green also ... but it seems as though it still charges more when left plugged in longer.
Some apps also like wp7 news clips off about 1 to 2 percent battery everytime i run them. (it brings in feeds from 20 different websites (estimate, i didn't count) so it's worth it but i check it a lot.
Could be wrong but as far as im aware that over charge protection. Your phone shouldnt really be charged 100%. 90-95% should be the sweet spot. Generally when i first noticed that i used to restart the phone and charge it to 100% but my battery life actually got less than just letting the phone decide when its enough
My titan has recently been getting more and more life from the battery; upwards of two days. I turned off wifi and I got 4 days 4 hours, died just some hours ago (I don't game much, but I do listen to music).
I've been getting into the habit of charging it when it gets below 5%, not every night like I used to. So it'll be 30% at night sometimes, and it'll last me another day with light/average usage (as opposed to my previous mindset where anything below 50% is a no go).
It might not work to leave till last 5% especially for someone like me who travels a lot. Don't you fear at times that your phone might faint when you really want to use it? As soon as my phone goes in battery saver mode I plug it in. Maybe that 90% limit as a reason. Over riding it helped me but if I did not over ride the following cycle then my battery performance seemed awful! Very strange working indeed.

If I plan on using it AND I know I'm going out where there is potentially no USB to charge with, I bring my portable USB battey charger and/or one of my other phones. However, I don't mind not having a phone with me at all times, so if it dies, it dies. Still, I just got it to last 4 days, so if you don't watch videos or play games frequently, charging every three days is unheard of for a smartphone!
The battery's health relies on charging it properly, and I value keeping this up over having it charged when convenient for me. Battery saver kicks in at 20% I think, and with battery saver, you'll get almost another day with light usage, so charging when battery saver turns on is probably really hurting your battery.
I generally unplug my phone when I notice the LED turns green (even if I'm going to bed for the night I'll unplug it). I have never had such amazing battery life with any other phone, but I also have never taken such lengths to improve battery life either.
Why don't you pick up a brand new HTC Evo 3D battery off eBay or something and use that? Its a 1730mAh battery compared to Titans 1600mAh and works fine in the Titan.

Deep discharging a Li-Ion is worse for it than frequent charging. Temperature also is very important and I haven't noticed the battery get hot when sitting on the charger after the light turns green.
My appologies if this question has been answered somewhere else, I could not find any other threads with a similar situation.
My phone was dropped and ever since then it has not shown me the right battery level. It will charge on USB or AC up to 99% and stop. I connected it to AC power 30 hours ago and it never gave me the green light. This is after a full drain and then recharge. It did however stop charging at some point. I noticed no light was on, red or green, turned on the phone and my battery had gone from 99% to 41% in 22 minutes. I plugged it into USB and it appears to be charging back up. My widget now shows 84% with 4334mV (i dont know if this is right or not).
It is not an issue with the battery. My wife has the same phone and I swapped batteries. Mine works fine in her phone and I have the same problem with hers.
My other issue is that when I use the phone off the charger it will not show me the level accurately when it is draining battery. Example being, I unplug the phone at 99%, within 5 minutes I'm down to 92% (i know this is not unusual because of how the batteries charge). But, I will stay at 92% for hours and hours, with moderate use of internet, phone, and apps. Then it will fall from 92 to 60 ish in a few minutes and do the same thing. Sometimes it will tell me that I'm getting low (under 15%) other times it just turns off a second or two after the notification. If I plug in the phone and turn it on it shows me 1% and charges up to 99%.
In the few minutes I have been typing my phone charged up to 91% with 4336mV.
I was running ViperRom ICS when the issue started. Restored it back to Stock with no root and the issue remained. Now I am running Mean Rom ICS with the same issues.
I have cleared the battery cache in recovery too.
Any help would be appreciated.
If you kiss it. your phone will love you and it'll be all better. NOW KISS IT AND TELL YOUR PHONE YOU'RE SORRY FOR DROPPING IT! LOL!
Based on my experience with batteries of all kinds, it sounds like one of the cells may be damaged. Best bet is to get a new battery. They are decently cheap for a good one. Im actually looking for an extended unit myself. If you come across one, please PM me.
Thanks
That was my first thought but when I swap my battery with my wife's battery I have the same problem. Both batteries work fine in her phone but not in mine.
Sorry to bring this up again, my bad. But seriously you are not the only one with this issue.. I had the same problem since stock, swap battery didn't help either.
This is not happening for the first time...
Ever since I rooted my device and flashed Android Revolutionary Rom on it, I noticed some weird behavior with my device/battery.
Last night I drained my battery to 6% and I turned it off. This morning I charged my phone with the phone stayed off and when the battery indicator screen lighted up it was showing that 50% juice remains. Since this is not happening for the first time, this time I would like to test on it to see whether there's really this much juice remains. So I turned my phone on and as expected, the battery indicator shows 50++% left. So I play around with it and I noticed the screen flashing terribly after some time. Not long after that the phone hang there and I had to do a hard reset by pulling out the battery. Before that, I can see that the battery is drained to around 20%. I was unable to power it on after pulling out the battery and when I connected my device to the charger, nothing happens (no display, no LED). So I left it there charging and after some time, finally the LED is lighting up (So, I assume that I drained the battery COMPLETELY just now). I can switch on the device afterwards and it shows 6% battery remains. I wonder why is this happening as this only happens when I charge my device with it turning off. Something wrong with the battery? Device? Or I have to do battery calibration?

Let it charge to 100% first before using. Then check how is the battery usage.
There might be an issue with the battery also. If it is swollen then it's time to get a new one.
Try using another battery and see. If it works fine on other battery then your battery needs to change,
The problem could also be in the ROM. Something could have gone wrong during installation even though it may look fine. If this is the case then reflash the ROM with a full wipe. If the problem still remains, return to stock rom and see.
I had the exact same problems, the screen flashes and stutters, network signal is lost and the phone turns off, it is due to uncalibrated battery.
There's a simple fix, download battery calibration from play stor (green android icon with percentage), charge your phone to 100% without using it, then click battery calibr. inside that app, then doscharge it till 0% (do your normal usage as ussual) and then charge it back to 100%
For healthy battery life don't let it drain lower than 10% it's the li-ion physics and always charge it fully, don't charge from 0 to 30-50-60% because the ions in the battery will not have a good flow.
Everything has it's lifespan but if it's configured and used properly it can have a long lifespan
Also to mention, if my recommendation doesn't work, your battery could be swolen due to inproper charging / heavy oc-ing or your charger is messed up.
Also to say, that flickering occured to me when i flashed a new rom and when i do lot of reboots, then the batterystats freak out, the voltages also and also your phone.
Charhe and use it properly, try to stay with a rom at least a couple of days to see how it'll go.

Yea, I will try to calibrate my battery to see if it helps
I want to share the battery problems are back again after upgrading to Oreo ROM(new bootstacks) with a new battery.
So battery life issue? Im so happy i did not update to oreo from B9 7.1.1
Wipe cache partiton?
also, Do the whole 0 to 100% thing to calibrate battery. install gsam and Akku app to see battery info,check for anomalies.
maybe this helps, maybe it does not.
when my battery is charged for 68% and i unplug it on 68%...1 minute later it sits on 69%.It charged 1% when not plugged in.Or when my phone boots on 53%,i unlock with pin and then it drops to 52% and is stuck on 52% for a long time.Weird.
I would support Pruikki about wiping cache partition and calibrating your battery. I had problems similar to yours and have solved them (hopefully) with both of the above.
My battery is the original one and the device is about/a little bit more than 2 years, currently on B03 Oreo. I am sure my battery is still OK but after recent OS upgrades it went mad. The phone will turn off sometimes at 51% battery, sometimes it will reach 100% in 40 minutes from almost empty, or I will see battery charging 1 percent up every few seconds. Or even the phone will turn off at 23% but will show more than 50% immediately when connected to the charger.
I'd try discharging the phone completely until it reaches zero but real zero. The last time it happened to me, the phone turned itself off at 17% claiming it was empty. I started it on and the battery showed 17% (not zero) and stayed at 17 for quite a while. However the first time the phone got loaded, like watching YouTube video in the browser, it turned off again on its own. This repeated a few times until I made sure that the battery was completely squeezed off and not only I couldn't start it but when connected to the charger it shows the left yellow bar and no percentage.
Then you need to connect it to the charger but not turn on and make sure you charge it to 100% while it is off. I'd keep it at 100% for a few minutes to make sure it really reached it. Then you start the phone and let it boot. It is recommended that you repeat this procedure again - discharge again to 0, charge to 100% un-powered, then start over - although once should be OK too. In my case, the phone does no longer turn off before reaching zero but I am yet to see how long this will last. I wiped off the cache partition too since it stores various data that may interfere with the settings, especially after software update.
This does not work,i also recommend you dont do this...this make the battery worst...i already tried.
its possible to charge to 100 but when you unplug it,it goes to 99 directly.
I also tried other bootstacks with other twrp version.And sometimes it shows other battery% when i did not plugged the charger
For me it works but I am stock. I'd sometimes charge it to 93-94% before 7am, will use it slightly throughout the day for Instagram, Whatsapp, some browsing, music listening on the way to and from work (1 hour at least total) with about 1-1.5 hours total SoT and around 8pm I'd still have some 15-8% when connected to the charger.
This is after wiping out the cache partition and doing 0-to-100% charging while off and no restart yet. Battery really goes 99-98% upon starting it upon the battery calibration process when the charger is off, still it works OK now. I noticed that after every restart phone memories the battery state prior to the restart and sometimes will turn off at this level long before zero. I don't say it will be the same for you, but this is how it does for me. I don't dare changing the original battery myself and will keep the phone for as long as it functions, even if I buy something else.
Nothing, really nothing even of the current flagships (apart from LG but there are loads of other issues there) offers dedicated second amp, fully rectangular screen at 2K (not the sh*tty FHD+), not to mention the amazing front facing stereo speakers with Dolby Atmos with extra internal settings (not just on and off button), and 3.5mm phone jack and not some mediocre adapters all at the same time. Sorry, but if ZTE offered the same device with bigger battery, improved camera and SD 855, it would have overtaken the sales of any so claimed flagships all around, even if it matched their prices. At least I would have gone for ZTE again...
