I previously made a thread regarding low battery life.
After a week of use and more testing, here's what I gathered.
(Note: I have GPS, Bluetooth, Wifi always disabled, brightness lowest)
My phone will completely drain out in 6-7 hours.
I found the culprit: Cell Standby
1.) Cell Standby always uses the most battery, often 60%+.
2.) Phone Idle often follows with 30%+.
So, to verify my theory that the screen isn't the issue, I turned on airplane mode.
I proceeded to watch a 1 hour comedy, and battery life dropped from 60% to 50%.
This is lower battery usage than if it were sleeping with cellphone on.
I then noticed that my signal hasn't been good (provider sucks, no choice, all of em here sucks).
So, I placed my phone on, but asleep inside a locker for 2 hours (no signal).
When I took it out, it was very warm at 40+ C and battery life dropped about 20-30% per hour.
I've tried turning 3G off, turning always-connected off or downgrading 2g.
The result has always been the same. It still sucks bigtime.
It seems like Nexus One also has this problem, anyone notice similar problems?
I've googled and been told that this is "normal", because the phone increases power to secure a signal.
However, I've clearly owned phones and placed them in signal-less lockers prior to this, and trust me when I say most of them drop 5% per hour max.
20-30% per hour is horrible, and clearly the phone is overpowering its components.
There are some certain Radios you can flash to improve how your phone uses power to pick up a signal, Requires root access tho.
Can you please point me to those radios? I've already tried updating my radio to latest.
My phone is already rooted.
My battery is a joke and I have tried many different things. I always have to charge it by around 3pm everyday during week as It will almost die on way home.
I take it of charge at 7.30am by 9.30 it could be down to 86% and then it judt continues to drop by 3 It can be between 60 and 50% if lucky, by time i'm tenmins from my house I get 15% and warnings.
I use basically for txt, some net usage and sometimes playing a game 10 - 20 mins tops and or read ten mins of books.
I have all updates off only manual and screen down low etc - doing my head in!

Im facing the same level of battery drain, but i have 3G turned on constantly with updates from facebook every hour twitter updates every 15 mins and mail app every 30 mins. And i mostly use my phone for music and SMS with occasional browsing.

Strange, I always have 3g on, and still play a lot with my hero (games and such)
Still it survives about 36 hours on 1 battery load. Without 3g it holds out for 72 hours.
Post #1 on the thread below seems to have a working solution (re-interpreted below)
It seems to be something to do with the battery stats and charging via usb through PC instead of via the mains.
You have to clear your battery data when your phone has really really low battery (this is probably the MOST IMPORTANT step) (you can do this through recovery mode in amonRa). Once the battery data is clear, switch back on (before plugging in) and drain the battery so that your phone switches off by itself (playing music loud and switching wifi, data connect etc, etc is suggested in the thread).
Once battery has died, plug in your phone WHILE it is STILL OFF, then when the battery shows green (will probably take longer to charge because this time it is getting a full charge), UNPLUG BEFORE you switch it on. and you should notice the significant difference. - Oh yeah make sure you switch off all those data connections and wifi and all those other things that you used to drain the battery - unless you use some of them of course
EXTRA TIP given on the thread: TIP!! Remeber when changing and flashing new roms to unplug the phone from charge *(i.e. unplug from your PC) (edit Bad4ss) * after you boot!
TO answer LennyUK's Q below ( and so that the next page doesn't start to quickly before this suggestion is read ) I think why it is suggested for the first boot after this process to be done while off is because it is already off because of the drain AND because it will get a clean full charge up for the first time after a battery data wipe. Because while it is on it will be depleting the battery even if it is in a small way - after that you can do it whichever way you want *nudge-nudge-wink-wink-say-no-more*

I don't see why the same thing cannot be achieved by charging with the phone on, just as long as you don't change between phone being on or off during the charge i.e. if you start charging with the phone on leave it like that the whole time and visa versa

Can you do this on non rooted phone? How do I get into recovery mode?
I think the analysis is flawed. I also think the stats information doesn't tell you everything. For example, yesterday I had 60% cell standby, 20% WiFi, 20% phone idle. Consumption was 45% in 24 hours.
Previous to yesterday, I had high battery consumption. So yesterday was a breakthrough but YMMV. I removed the PCSCII and the Mail app (I don't sync with Exchange and I don't sync with a PC as such - I don't run Windows). I also disabled auto task killer. I rebooted without being connected via USB to power or to PC. Suddenly power consumption became similar to Modaco ROMs.
Last night, I also disabled the setCPU application and rebooted. 6% battery consumption in 9 hours. 34% cell standby, 33% WiFi, 33% phone idle. Consumption was 45% in 24 hours.
how have you improved battery usage, ive tried resetting battery stats, draining battery, fully charging, using kimera 1.5 and with no wifi no bluetooth, not using phone in few hours it was down to 63% and in 10mins had dropped to 59%
i had similar battery problems but today i changed radio versions into a different one, now i get almost full signal all the time and battery usage is geatly increased (went down 2% in 4 hours as compared to 10%/hour)
so i suggest finding a radio that give you good reception

im on tmobile uk, changes radio from
63.18.55.06JU_6.35.09.26 to
63.18.55.06JU_6.35.08.29
made alot of diference
you should ty out diferent radios and find one that gives the best reception, it will be different for different providers and countries
also i did this...

i unplugged my phone from the charger after doing this at 6am, it had 100% charge
its now10:45 pm, i have 44%charge left...its crazy
before i used to run out of juice around 10 hours after i charged my phone, its not been almost 17 hous and i got 45% left
i seriously suggest doing this

I will use that radio too seeing as I too am on T-Mobile in the UK. When you say to use the link and suggest doing it, I take it you mean the "get to 10% -> get to recovery mode -> wipe battery info -> reboot and drain battery 'til off -> charge while off and the take off charger once charged and switch on..
'cos I tried that and still having problems - am using the new Villain 4.0 beta2, so maybe the radio change in combination to this is what will work - I'll try it tonight when I get home.
immya : many thanks i now hove phone back
flashed radio 63.18.55.06_6.35.05.31
and lost 1% over night
previously on LOST
radio 63.18.55.06JU_6.35.09.26 lost 56% overnight
perhaps issue with 2.1 roms is the latest radio and not latest kernal
BTW using sensehero at moment as was trying 1.5 roms to get better battery, and that didnt work.
some one maybe sticky this info , if anymore find it a saviour. will report back after work, mayeven be able to use data syncing again
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?!
Ok so Here's the deal
When I flash a rom I charge the phone till it hits 100%. I then reset the battery stats and go on about my day. With in a few minutes of being off the charger my battery has now dropped down to about 96 %. I do realize that batteries do not stay at 100% but this is crazy. I've only deep cycled my battery once for fear that it may damage my battery.
I Am using Teamwhiskeys ultra awesome bionix-v rom with ttabals oc kernal. I know I am to expect a slightly more rapid drain but this is crazy. I have even tried to lower the vcore and I slowed down the cpu to 800mhz. It still drains just as fast.
The odd thing to me is If i turn my phone off and let it fully charge to 100 percent reset stats then turn on phone It will show full for a minute then drop down to to 96 or 95 percent.
I personally think my battery is damaged but spare parts shows that it is ok.
So i am rather confused by this .
I know I should probably use the stock kernal but it seems like its just as bad with that.
I have looked at the threads about battery life and I am not expecting it to be amazing just hoping it will be ok!
Tell me what ya think !
mt battery play tricks on me too when my phone doesent see that im lookin at it it shows 90 when i look at it and phone notice it bounces to 85 like it hates me , lol but dont take my words for it P
Spare parts would show that too. I remember when I had my G1 spare parts would tell me it was fine. But a 3 hour full battery doesn't seem fine does it? Id suggest getting it replaced.
Sent from my HTC Vision using XDA App
Ill probably nurse it... but I am having major ocd type problems about it.
I cannot stress this part enough, so I'm putting at the top, do not do the following often, as it can have a negative effect on Li batteries if done too much.
You want to try what is known as a bump charge. With your phone off, charge to 100 percent. You will see the green battery icon with "100" on it once it reaches full. Unplug from the charger for a minute, then plug it back in, phone still off, and let it reach 100 again. If you want you can do this a third time, do keep in mind, bump charging too much or with any type of frequency can have negative effects on your battery, but doing it once in a great great while helps with with what you are experiencing.
thanks Br1cK'd and those who replied.
I have tried the bump charging method. I am affraid that my efforts to repair my battery are causing it more harm than good.
ok i just restored bionix v and had it charge to 100 percent
spare parts says
battery level 100
battery scale 100
battery health good
battery voltage says 4243mv

There is one thing you are messing up. If you flash your phone on a 100% charge then you DO NOT need to wipe battery stats. You only have to wipe battery stats if you flash when your battery is not at 100%!

With in a few minutes of being off the charger my battery has now dropped down to about 96 %. I do realize that batteries do not stay at 100% but this is crazy. I've only deep cycled my battery once for fear that it may damage my battery.
I Am using Teamwhiskeys ultra awesome bionix-v rom with ttabals oc kernal. I know I am to expect a slightly more rapid drain but this is crazy. I have even tried to lower the vcore and I slowed down the cpu to 800mhz. It still drains just as fast.
The odd thing to me is If i turn my phone off and let it fully charge to 100 percent reset stats then turn on phone It will show full for a minute then drop down to to 96 or 95 percent.
I personally think my battery is damaged but spare parts shows that it is ok.
So i am rather confused by this .
I know I should probably use the stock kernal but it seems like its just as bad with that.
I have looked at the threads about battery life and I am not expecting it to be amazing just hoping it will be ok!
Tell me what ya think !

It's not out of the ordinary for a battery indicator to show a few percent drop rather quickly on a LiIon battery. Secondly you should take a battery indicator with a rather large grain of salt. Expecting precision in single digit percentages from the indicator is unrealistic and nearly impossible to rely on given the nature of discharge of a battery. Batteries do not charge or discharge in a linear manner, and people do not use battery powered devices in a linear way either.
It is a visual guide, not a precise and accurate indicator. Many custom roms have a percent accurate indicator, but don't mistake this with being dead-on accurate. It is merely an attempt to make it a BETTER visual GUIDE.
To evaluate battery life properly is moderately time consuming, though rather obvious. Use your device as you would normally. Pay attention to how long it stays charged. If it's not staying alive for a reasonable amount of time (12-24 hours depending on what you are doing of course), then it's time to dig deeper. Apps that wake up and generate unnecessary Partial Wake usage, a lot of background application syncing or apps with short sync intervals, being in an area with poor data/voice signal....these are the usual culprits.
Apart from situations where people are playing around with experimental kernels (i9000 derived kernels tend to vampirically drain battery a few percent an hour regardless), the things that drain your battery are....things that "use" your phone. The more you do (and the more your phone is doing with your permission while it's in your pocket) the less battery you will have.
In the end it comes down to asking yourself some questions. Do you need to automatically update facebook, myspace, twitter feeds constantly when you can manually update them and be inconvenienced by a 10-20 second wait? Do you really need to update 35 rss feeds in Google Reader?
Most people's power related issues come down to three things.
1). Apps that wake up without your knowledge and waste battery for no good reason (I'm looking at you Media Hub!!)
2).All those other apps and widgets that are updating inside your pocket when your not reading, watching, or caring about them.
3). Being in an area with poor data/voice signal, forcing your phone to "hunt" excessively for a better connection.
Apps that wake up and do god knows what without your knowledge can either be removed, disabled, or frozen. Examining partial wake usage can give you insight into what may be going on in that scenario. Apps can be "Frozen" with Titanium Backup Pro (paid) or App Freezer (free).
The other part that is within your control are all the apps/widgets you actively use, and your decisions about how often (or even if) they update themselves.
One of the worst things you can do to a lithium battery is discharge it completely. They don't suffer from "memory" yet every time someone here in the forums complains that they are getting crappy battery life the instruction to discharge and recharge to 100% before clearing stats pops up.
For those who are interested here is an article that explains in detail.

My main question- Is there some function in android that looks at the maximum depth of discharge level of the battery or is it that most people don't understand the characteristics of L-ion and confuse them with those of Ni-Mh or Ni-Cad?
I want to know because if I need to completely discharge to get better perfomance, despite the reduction in charge cycle lifetime, I will do it but only infrequently.
I've only let my battery discharge completely once, and it wasn't on purpose. From the posts I see here I think I get above average battery life. About 18 hours miui before I go for the charger and on 2.2 roms I'd get 20 hours and still have 40% or so to go. So no I don't think completely discharging your battery does anything for battery life.

I have never run mine down completely. Gotten it to about 6% but that was because I was fighting ROM flashing problems. I usually call 25-30% enough for me and plug in then. I am also getting 30 hours out of my 2.2 with a good deal of use. I used to have a Motorola and their batteries are total crap. If you EVER let it get down below 10%, it took some real work for it to charge correctly and boot up. Even as much as a hardware mod where I have had to cut the wires on a USB charge cord and charge it rigged up with the wires pressed against the battery and prongs in the phone. Very dangerous, but worked for a last resort.
Discharging the battery is not for the sake of the battery,but more so for the ROMs data and how it acquires the battstats usage. I only run it up and down and clear stats when flashing a new ROM, but I do use my phone moderate to heavy daily and have had great success in battery life the way I calibrate it.
The solution I think is to use a larger capacity battery and regulate it to narrower window of operation never fully charging or discharging.
The fastest killer though seems to be heat.
I have read several times that your phone does not fully discharge the battery...that there is still a minimal amount of charge,not enough for the phone to opperate but enough to not damage the battery when it shuts down
Maybe the batterystats file can be saved after being calibrated once and then restored after every wipe oor flash.. that would save some time aabd according to you guys, batt life too
Sent from a cell tower to the XDA server to you.
I've only ever calibrated my a few times and only after flashing a new rom. I never run my battery down after resetting the stats. I just use my phone as I normally do. My understanding of calibration is that it's not about squeezing more life out of the battery despite what most people think but of getting a more accurate measurement of the battery's actual charge. Also while it's true that the phone will shut of before the battery is completely discharged damaging the battery, allowing the battery charge to drop that low shortens your battery's life and decreases the amount of charge your battery can hold.
What gets me is I also read somewhere that for optimum battery life you should keep your battery level somewhere between 70%-40%. Of course that doesn't stop me from charging my phone to 100% everyday. I don't remember where I found that article but I'll post a link if I can find it again.
The reason this bad advice about completely discharging your battery persists is probably the same reason people keep recommending automatic task killers.

Discharging the Battery & Running the Battery Dead is 2 Different things!
We recommend running the battery dead ( Phone Shuts Off ) & recharging while off to train the Android OS from Full > Empty..
Running the Phone until Dead is not Going to hurt the Battery in anyways shape or form despite what you may think or read!
The Reason is, the battery is never fully Discharge & still holds Voltage.. The Calculations of Charged / Dead is at the Kernel Level, so even when dead it still has a 3.4v still or roughly..
As long as the kernel isn't tampered with, discharging the battery via the Phone will never hurt the battery period!
Now, Based on the link you posted you would have to run the battery down past the safe discharge point.. Via some other means of killing the battery, other than using the Phone.
To help ease your mind, Remember this:
~ Charge levels is controlled by the kernel
~ Even when Phone powers off, there is still plenty of charge in the Phone's Battery
~ Battery is never Fully charged, as this also hurts lithium batteries
Roughly every Android kernel does not let lithium battery get below 3.4v and at most 96% charged.
Hope this helps,
~Eugene
If you are still concerned wait until your phone turns off and stick your battery on a meter. You will see there is still power left in it...
My original battery that came with the phone got great life, then couple of months later it was discharging in like 2-4 hrs(froyo), so I called, they sent another one free...5-6 months later that one started doing it as well, so I pulled out the old one from the drawer, it powered on at like 85% ! and I was getting crazy ass life out of it on miui over 30 hrs one time...now that one is acting up again, so I'm going to try to swap again..lol...maybe there's something to not using them for a while...
I've used diff roms and combinations of draining/recharging...calibrating, not calibrating...it's always different results..honestly I don't think there's any rhyme or reason to it other than the fact that many vibrants have diff hardware and there will always be some weird quirk on a per user basis...
As far as hurting it by draining it all the way, I hardly think that's the case seeing as with both batteries I've always let it run down...not on purpose but there has been many many times I've plugged in at 1% or had to power back on because it died...charged it up and got 20-30hrs no prob..usually issues come up when flashing a new rom...
i think it all comes down to luck of the draw. ive had my vibrant since launch day, and i still manage great battery life. my battery is actually stamped 7-02-2010. every 2 weeks or so ill drain the battery completely, turn it back on and allow itself to die again, and finally allow it to fully charge overnight or 4 hours. i usually get a good 7-8 hours of constant use on cm7, or over 24hours if let on standby.
im still debating if i want to grab an epic 4g touch battery as well to increase it even more.

in there they tested in a store since the epic 4g touch battery fit into a regular epic 4g, if it would fit into a vibrant. only thing is you have to put the battery in facing inside, and it fits and works 100%
Yeah the Epic 4G batteries fit in our Vibrant's. You can buy knock-off one's (that work well) for 19.99$ US! Here's a thread about it...

Epic touch battery for the win. I've been rocking it for a few weeks. I was on miui and getting 14-16hrs. I recently went back to froyo and yesterday I got 12hrs off of a 67% charge.

Lol one of the biggest flukes in our forum haha.. people will harm their battery to calibrate it and it doesn't even do anything ...
Thank god I only calibrated once

Hi this is my first ever post so please bear with me, my lumia like many others suffers from ridiculous battery drain I have the new software and yes I can now charge to the max. However the battery cannot last the day out until I discovered this. Most people I know continually top up there battery, but if you just let it completely die then do a full charge overnight you may like me notice a massive increase in battery life, I have changed nothing about the way I use my phone the only difference is it now lasts 2 days easily.
The figures quoted in battery saver have not changed but as the day goes on the time since last charge goes up but so does the estimated battery life.
My phone is now IMO fantastic.
Maybe if you tried this it might work for you too, do hope so.
One word of caution when the phone has died the phone cannot be switched on until charger has been plugged in for some time, in my case about 20 minutes after plug in the phone switches itself on.
Please try and maybe you will also have the most amazing phone too.

I think I experienced something similar. I then flashed the new firmware and am back to lower battery life. Need to take the time for a few discharge cycles.
The problem with this approach is that some Lumia 800's cannot turn on after a full discharge. People have gone to great lengths to be able to get a tiny bit of charge so that it could power on. Some people have had to send them back for repair.
Question to TS. Do you let it completely die every time now or can you charge it whenever and still get the great battery life?
battery fix maybe
Hi after letting the phone die I have not done it again since, I just top up as needed or at night just as you would normally do.
Hope this helps.
Okey. When you say "completely let it die" do you mean letting it drain and turn off. Or do you start it once again after the first turning off and let it die again?
battery fix maybey
Just use the phone till it turns itself off, then plug in charger, this is when you may have to wait for the phone to switch on, mine turns itself on after about 20 minutes, charge as normal then use as normal, charging as you would normally do.
Good luck.
I did this once intentionally about two weeks ago. Did not notice any difference really. I do not have "bad" battery life to begin with. Not great either though. But it easily lasts a full day with heavy usage which is all I need really.
12 hours since last charge. 73% left on battery. I have used it "normally". About 10 quick calls. A few messages. Browsing on the marketplace installing a few apps editing contacts etc...
I'm pretty heavy on my usage, too. Lots of Mix Radio, sometimes played via bluetooth.
