Before you suggest i change the battery.. it's just fine.
the problem started the day i flashed WM6 (over a month back) and has only started to bug me lately as my phone died on me 3 days in a row.
basically the moment the battery level gets down to 40-50% the phone just dies.. i could reset it and it powers up for a second or so then it dies again.
i flashed WM5 back.. and the phone was working fine even if the battery level reached 10% (i get a warning bubble but it doesn't just die on me!)
i've searched around and noticed the only suggestions were to change the battery, which seemed kinda useless as i'm almost sure the problem is somewhere in WM6 power management/battery handling.
any comments?
Try another WM6.
If you used Helmi's/Jwright's try DarkForce's/PDAVIET, or vice versa.
Mate I can get mine to die at 90% battery just by switching WIFI Bluetooth and opening a CPU intensive app (Google maps/Tom-Tom).
I’ve ordered a new battery and its coming next week so I will see if this is any better.
This is more than likely a Current problem, an in the battery cant supply enough amps for the phone to function properly, im almost certain that the WM6 ROMS do cause more current to be drawn from the battery but it is most likely that this is just highlighting that the battery is on its last legs.
Ill post back when the new one comes, If its doesn’t fix my problem I will be flashing back to the standard WM5 ROM to do some tests.
its probably the battery
i had the same problem. a new battery fixed it. it would die at 45% but now works all the way down to 5%.
new batt or borrow one from a friend to test.
I have seen the same thing on the BA fora as well: It's not that the whole batery is dead, but some of the cells in the battery are.
There it was also fixed with a new(er) battery...
I had to add a comment
I use a Exec with WM6 and i have a MDA Pro that i keep trying different roms on so i can use and mess with it and at the same time keep my sort of stable exec for work.
i do swop batteries between phones and so on, i cant say what roms i am useing when this happen but i have the same problem on the MDA Pro 40-45% it shuts off, reset and it starts for a second then shuts off, so i then put the battery from the exec ( charged ) in the MDA and away it goes my exec happly sits there at 40 or so % and will go down to 0 flat.
So its not the battery its the phone, but as said by someone else it could be dependent on what rom i am useing at the time
It is the battery..100%...pls buy a new one or try exchange from yr friend..nothing wrong with the Phone..
I tested every wm5 and wm6 roms and i have two batteries: one dies at 35% while the other never dies but gives warnings on the red side.

I still think the main problem is the battery.
But I think WM6 just uses more power intensively then WM5 does. That would be the reason the phone dies.
Mine always goes back on again but then dies booting the OS.
Had the same problem with old PDAVIET rom
Hi, had the same problem with the old PDAVIET ROM 2.08 somethign or other, but since upgrading to 2.10.02, everything is back to normal, and lightning fast.
Try the newer ROM, and then see if the same happens, and if it does, then it is the battery which is definately causing the problem.

I have read somewhere in these forums that when the Networks release their official ROMs for upgrades they all clearly state that you should ensure your battery is at 100% charge as when you run the ROM upgrade the battery management resets its self to the level of the battery.........ie it assumes 100% but if your battery is at only 50%, then 50% becomes what it believes to be 100% therefore half the battery life.
I have to kind of agree with this because my first WM6 upgrade I was so eager to do my M5000 had only been on charge for 10mins or so and after the upgrade battery life was awful, however since then I upgrade only after my M5000 has been at 100% for about 30mins and since have not had any issues wahtsoever with battery life
Hope this helps

I thought it was because when you put your device into BL and flash it to a new rom, during the upgrade the phone won't charge.
So if you update with only 10% battery the device could turn off during the flash, and that would be a bad thing.
So they state (advice) to charge it to 100% before flashing.

Wrong. The previous poster is 100% correct. Better charge your battery to 100% before flashing.
What should I do if I had ROMed my Uni not in 100% bat.?
Your PDA needs to be fully charged because during the flashing the battery is not charging. So if your phone runs out of battery before the upload has finished you are screwed.
I never believe that the state of the battery is been used as the 100% level of your battery during flashing. I make elektronics myself, the battery level is always measured elektronically.
I had the same issue. I fix it with a new battery and works fine since then.
A bit of both
WM6 does use more current compared to WM5 and most of us have been torturing our Uni's with all the flashing we do (We don't use them as a phone much more of an intellectual playfield) . Also most of us have had the Uni for a year and some longer. My XDA Exec is 2 years and T-Mobile MDA Pro a year in sometime. The batteries are a bit older and unable to supply the increased power as before. I do have this problem if I use the older batt on WM6 and the newer batt works just fine. But then again the older batt works fine on the MDA pro (unchanged with original MDA Roms).
Cheers
Battery
Hi,
i was suffering from the same batery issue in the last 10-12 months, and let me share my experinces. After my original battery started to die first at 20% and finally at 50% i bought a new one. I read tonns of articles about LI-POLymer batteries and tried o follow as it was written. The result : after 4 months my new battery is in the same state. I bought 2 other. When i started to use the first, i had always recharge it between 10-20%. Now this battery dies at 12-15%. I let my latest battery to go down to 3 % ALWAYS and after 5 months NO PROBLEM AT ALL!.
So my experience:
-let the bttery go down. I don't care what other experts say about the characteristic of Li-Polymer. For me it seems that practice is different.
-NEVER,NEVER,NEVER cahrge the battery if it is not empty. In my car if I want to use my UNI for listening music or GPS then i REPLACE MY GOOD BATTERY with the old one, and then i use the car charger. With my laptop i use only BLUETOOTH connections
-ALWAYS USE original charger. No laptop, no car charging
-If i do an upgrade for any ROM i ALWAYS DO THE UPGRADE WITH THE OLD BATTERY.
-USE at least 2 batteries, one is always charged fully, and if the other goes down you can replace it quickly
I am sure that there are many experts, who can tell me why i am wrong, but the pratice seems to work for me. And i have not found any experts who could explain these strange situations with UNI. Now I have 3 batteries. All is about 10 months old. One dies between 30-50%, the other dies always at 10-12% and the last always at 2-3%.
crikey, the device is big enough as it is without carrying around more batterys. Mine's starting to die at 70% now. When it reboots it seems to die when the radio stack is activated. Had it for 13 months now my stylus falls out too had to put cellotape around it which has sorted it.
Just waiting for three(uk) to bring out the tytn so i can move over with their x-series stuff!!! woohooo!
I've had mine about 13 months now and it started dying at 40% left then 60% then 85% (of battery left!). I bought a new battery and 3 days later without charging it's still on 65% left

Hi All,
Got this funny problem since I have flashed TNT WM6.1.
My mobile battery shows some funny traits.
1. It can suddenly go off (even if the bar is at 87% or 63% or 30% or anything of that sort)
2. Once it goes off, it gets into a loopback of restarting the device, goes upto the screen where WM6.1 logo appears and restarts again.
3. The only way I can then get it restarted is to get it to plug to a powersource.
4. When I plugin it shows within 5 min that the battery is fully charged.
5. I use audio manager a lot and its like every 30 seconds 1% of battery is gone.
Have search through the forum but haven't found anything like this.
Anyone has face a similar problem and found any solution?
Any help will be much appreciated.
I am on SPL/IPL 3.08.
Time for a new battery....
I ran across the same problem. It turned out that the terminals on the battery were seriously worn down so much that the battery couldn't hold a charge to safe it's life let alone mine!!!! I went to a battery store and replaced the muthaf^$#a!!!!!
Go grab a new battery and you'll be electric sliding again in no time!!!!
Thanks Trej3k. Much appreciate your response.
Yeah
Had the same issue.
Replaced the battery ... and now everything is fine.
Now I don't expect 5 days without recharge but at least 2 days.
Along with the new battery I bought an battery charger so now I can use two batteries.
The nice thing is that the old battery is lasting at least as the new one, Maybe because of the charging more regularly and not so frequently and because both batteries never go in usage when they are hot of charge.
Try your thing

I had the same problem pretty soon after I flashed my ROM for the first time. I would charge to 100% and then browse the Internet or take a call, and the device would reset within a couple of minutes b/c it would think it was out of power. The timing may have been a coincidence; I don't know. I bought an extended battery and everything works fine now.

I had the exact same problem right after flashing to wm6. I really wonder if it's a coincidence.
I ordered a new battery today because I have exactly the same problem. I also apeared after flashing WM6.1 a while ago an became worse with time. Since my battery is 3 years old, it could also just be a battery at its end of life...

Hi people. I'm having battery problems since I bought my TP. I tried many ROM and Radios combinations and the problem persists.
Also tried discharging the battery and long charging while turned off (3 consecutive days) as recommended by some members here in xda.
Nothing solved. What could it be? A hardware problem (TP itself) or only a bad battery? Whats more likely?
I would like to know where can I buy an original spare battery to test this. Anyone know?
Thanks in advance!
google.... Here's one, but it's a yahoo page. Take down the oem # and start from there. Also, i think there was a little booklet that should have came with your tp about accessories... http://www.wirelessground.com/htctprooembatt.html
what about using non-official batteries? its risky? because there are batteries for TP for about 5 usd
You know that it will drain battery as long as it is in "sleep-mode" and not entirely powered down. You have to press the powerbutton for 3-4 seconds and then it asks you if you want to power off.

Of course, I mean my TP has a abnormal batt drain with normal use... the batt lasts less than 12h. I unplug it 10am and the battery is finished before 10pm depending on use.
have you by any change changed the TF3D theme?
i made my own theme, but i get the impression that battery drains much faster now. watched the battery fall from 21% to 18% in 3 minutes without doing anything besidesscrolling between TF3D tabs.i think themes might be making more use of the 3d accelerator and drain the battery..
I'm using default theme from ROMeOS v1.20

Do you have it turned on all the time in locked mode? Or do you put it to sleep/standby when you not use it?

Standby when not in use. Actually, while I dont use, the battery drain seems normal, maybe 2 days or more. The problem is when I use it.

How about upgrading the Radio Rom!? I have found since going to 1.02.25.28 and having ROMeOS² v1.21 my battery life is much better than stock Roms of both!!
Its something worth trying and easy enough to change back...
Has there been any good solutions? My battery life is starting to annoy me.
Maybe I'll pick up a second battery and charging cradle thing for it...
That's one thing that I liked about the instinct...
I think we need a Stock TP to compare it to .. I know when I bought mine for the first day or two without adding anything to it, I didn't notice an issue with the battery. Now that I've installed tweaking software, theme, etc - battery drain is definitely noticeable. I'm thinking it may have to do with one (or more) of the programs we put on the phone.
Anyone here have a completely stock TP with a battery problem?

tried all radios available in wiki page (except .11 and .16)
but that was with romeos 1.12 and dcs, I'll give a try for .28 with romeos 1.21
but I'm pretty sure that the problem is hardware, since many people use romeos 1.21 and radio .19 and dont have problems...
My phone had a very short battery life when it was bone stock too.
I'm afraid to see what it's like now with the tweaks!!!
mine is original stock TP batterry..but also facing the same problem. in average have to charge twice in a day..and the charging takes a few hours. so my phone is only running on battery for not more that 15 hrs in a day..
I'm hoping now thats its a bad batch of batteries problem and not a phone itself problem
I'm having a simlar issues. Put my TP on off/standby (single press of power button) at around 10pm, on flight mode enabled, all appliactions closed via task manger. Battery was at 80% when I did this. My TP's low battery alert woke me up at 4:30am at 8% charge.
My Blueangel used to last several days in the same state out of it's cradle without needing to be charged!
I to am hoping it's just a duff battery.
UPDATE: Seems I was being a twonk! I had unchecked the Auto-Shutdown option for a game I was playing and forgot to turn it back on, so my TP was turning on at midnight to do it's housekeeping and not shutting down again properly.
I still don't think my battery life is normal though, may try the following:

Found this on Sprintusers.com: It's an 06 post, but I wonder if it's still an issue. Found here http://www.sprintusers.com/forum/showthread.php?t=175896
Received the below from my Sprint rep.
It has been brought to my attention that there is a glitch in Windows Mobile phones that has been there since WM5… Apparently when a phone is first used the firmware looks at the charge on the battery as a reference point as to how long to charge it for until it is completely charged. So for example, if you have a WM phone that has a half charge on the battery when you first plug it in the device will only ever charge up 50% of the battery. You need to basically set the phone to put that marker in place when the phone is completely dead to gain the most battery performance you can.
Here is the best practice for doing this:
----------------------------------------------------------
1. Let the phone completely die on battery power.
2. Plug the phone in and charge for only about 5 minutes (just long enough it can boot up completely)
3. Perform a hard reset of the device, this is done differently depending on the phone model.
4. Then place the phone on charge for at least 8hrs.
---------------------------------------------------------
This should reset that marker that the operating system places on the battery charge cycle and will allow the phone to completely charge the battery rather than only a % of a full charge. This procedure can be done at anytime and I would suggest having your customers try this process first before returning a device based on battery life issues.

I have 2 SPVC600 phones and one is not even 24 hours in standby before the battery goes empty, whereas the other phone is in standby several days. I tried several different "virgin" ROMs on both phones, several different batteries, still the same problem, one phone just sucks the energy out of the battery like crazy.
Anybody knows where the problem is and how it could be fixed?
Thanks

Same Here...
Hi, i know that this is a old thread, but... the same issue here, i have a T-mobile SDA, replace the original battery that come with the phone 2 years ago, this battery die and ebay a fresh battery again, but... nothing, goes empty in less than 13 hours with the fresh and new battery (with the old one at least 4 hours before die under nitrogen´s wm6 rom), any suggestion? (i clean the phone of programs, change roms, downgrade to original WM5 but... nothing, only 12 to 14 hours and empty ), the new battery is a "OEM ST26" from sanyo...
Until this day, my tornado was the more reliable and trust phone that i´ve had
Can you recommend me any procedure for test the phone... do you think that is a usb connection Issue, i read in a lot of threads that this could be Rom upgrade... ´coz the new drivers, componets, etc.... any help ir really appreciated
Greetings from Colombia...
Usually the original batteries are the best you can get. Even the (now very old) original ones (Sanyo ST26-C) still have their original capacity and I have not seen a single battery of these that has failed until now.
If you see such a drain from the device you could possibly disassemble the device and clean it. If that does not help - sad :-(
Does it make difference if you charge the battery on the device being off or while OS is running?
If you have volt-meter: what is th battery-voltage when empty/fully loaded?
Hi Tobbie, thanks for the reply, yeah, i follow all procedures for battery maintance, i try charge with the phone off, phone on (with radio turned on and off, really i only see a difference of only 1 1/2 hours...), this night i try clean with isopropilic alcohol the contacs between battery an phone and i see... i noted something peculiar:sometimes when i plug the AC Adapter or connecting to my desktop, the led indicator (in this case orange), dont turn on, sometime this led appars and dissapear passing 20 seconds but full charge the phone (i see this in seetings=> energy configuration => 100%)... other times this light is hold until this change to green (fully charged), but ever the same result, lees than 12 Hours... this happen with both batteries (old one and fresh buyed from a reliable seller 15 days ago...)
I download awhile the service manual for tornado but... Scare... i really love this phone, really i have now a LG Incite, but this phone is my "backup", coz all time buy and sell phones, but this since 2005 "sleep with me...", if after clean contacts i dont see any change or fix... No mercy with tornado´s LOL...
and i want with all neighborhoods a voltimeter, can you tell me about the standar values for this battery (my knowlodgement about electronics are limited a lot), i post my results here after my test...)
Thanks a lot, i hope that you can help me later (and sorry for my ugly english)
Greetings from Colombia
This sounds weird, but the only reasonable source of evil is that also your other battery (equally aged, but unused probably) is chemically dead. It hardly ever happens that the charge-electronics is going mad somehow. With the many Tornado that I had on my desk, not a single one had problems with this part. For some devices I have seen that the batteries were stone dead - and these behave as you describe it.
It looks as if the battery has lost its capacity. A fully charged battery has a capacity of roughly 1100 mAh. With a drain of ~75mA (for the fully lit display) this will last 14h and 40 minutes. So a similar power drain would have to suck the juice off the battery - which I doubt that anything will do. If you switched off all radio parts (GSM, WLAN + BT) there is nothing left that drains the battery like this.
You could try to check how long the batteries will last when you have the display light draining the battery additionally. For this part it is well known how much it drains (see above) - and if you see that the battery lasts half the time of what you said before - then the battery is ok and the device has some mysterious power drain. If however the battery only lasts a few minutes with this defined load - then it is surely dead.
Check the battery capacity link in my signature to get the tooling for measuring this easily.
Voltages should be measured with a digital Voltmeter if you have access to one. They are for dead batteries not much different to good ones if you do not apply load, but a fully charged LiIon has around 4,2 V and discharged in a Tornado around 3,55 V.
The Tornado will shut off at around 3,55 V but if the Voltage is much higher when removing the battery and measuring the Voltage - another hint for a dead battery.
Good luck
My apologies if I am here with the same complaint, but I tried searching this forum and found nothing that works for me.
Basically, I rooted and flashed CM 5.0.8 and I have been having battery issues. Now its not that my device is draining battery at a very fast rate (seems it is indeed doing that), but I suspect there is some problem with the battery meter.
So from all the stuff that I read, I decided to recalibrate the battery. I charged it up to full, until the green light went off, until the status showed 100%(full) and then some more. I then restarted into recovery(Amon-RA 1.7.0) and wiped the battery stats and rebooted back into CM, while having the charger connected at all times. Its worth noting however that during the time the phone was booting itself into recovery or into the ROM itself, the charging indicator stayed off. Thanks to that, when the phone booted into CM, the indicator was red for a few mins before it turned green (charge had dropped 99%)
Now I've done this 2-3 times, including letting the phone die due to an empty battery, but I am still getting very little life from the phone. For the record, I have the end button set to sleep and I don't have any continuously running widgets and my syncing apps (twitter) are set to sync only every 1 hour.
Anyway, again I don't think these apps are draining much battery, since once the battery dies down and the phone switches off (after light to moderate usage as compared to the life 1.6 Donut gave me), when I put it back to charge and turn the phone on after 5-10 mins of charge (while the phone is off), the meter shows a charge level of around 65%. So I suspect that the battery charge is at around 50-60% during when the meter reads it as around 1% and forces the phone to turn off.
I also tried switching on the phone after it had turned off, but it switches off immediately after booting (at least on 1.6, I could reboot it a couple of time on a 'dead' battery)
Are there any other tips that I can use to recalib my battery? Any idea will be much appreciated as my phone dies out each day before I can get back home and put it on the plug. Should I consider upgrading to CM6-RC1? Has it been proven that the battery performance is better on that?
Have u tried swapping out the battery with another one to isolate it to possibly the battery itself? Isolation is key, that way could it be ur extusb isn't charging correctly or is it the battery?
Well, I do have a spare - the one I saved from my bricked G1, but I haven't tried it out yet. The battery was working perfectly well just a few days ago when I had a stock Donut. So, I suppose it isn't a battery problem, but no harm in trying out the other one.
i had issues with my lithion battery and found out it happened to be on its last breathe. And with my spare i had it worked good. did u drop the battery at all? with lithium ion batteries can be as delicate as expensive china or porcelain. And to be honest the batteries that came with our g1's aren't really that good. If you can I would suggest getting an ext. battery from ebay. ive heard that fully discharging a lithion battery isn't the best practice either. I'm no expert just experience Best of Luck!

reading the Cyanogen 5 thread I noticed at least 5 people with a broken battery...
for the record mine is broken too...
it's all swollen up... I mean, I can use it but it doesn't last a full day and it doesn't fit perfectly anymore in its slot inside the phone...
I'm starting to think that maybe for some reason flashing cyanogen 5 caused this issue, since so many people had this problem at the same time...
or maybe it's just a time defect of some stock htc batteries... who knows...
@GigiSpligi: Nono... don't blame CM for the swollen battery. Batteries tend to swell up after a lot of usage (charge discharge cycles). The battery on my old Nokia phone had swollen up after about 2 years of use. Similarly my friends E51 battery. Also my G1 batt seems to have swollen a little bit already. So nothing to do with the ROM.
Of course, if the ROM is making you charge frequently, then it is indirectly causing the effect on the battery.

The exact same thing happened to me ... actually on all ROMs now ... i'm gonna look into getting a new battery and sdcard which kinda sucks, but oh well. when i think about it, i wasn't have any problems till i started flashing sense based ROMs, especially Slide ROMs. so i must have done something wrong. i can't even make a phone call for longer than 10 mins before the phone shuts off and have to plug it back it into a charger just to get it to boot to the home screen
... hope there is a solution ... haven't read through this thread yet. just wanted to let you know you weren't the only one with the exact same problems

hahaaha well that didn't take long to read ... yeah my battery is somewhat swollen and i did drop the phone once ... time for a new battery i guess ... sucks
[x-posted from Cyanogenmod forums]
Ah well... gonna have to pull out a new battery and see if that helps in anyway. I will have a look at the device usage stats to see if anything is causing unnecessary drain. Since there has been a drastic change in the battery life after the upgrade, I do not want to blame the battery itself yet. Guess some app is driving the phone nuts.
Ok, I was just seeing the battery usage history in spare parts and I there are some interesting usage stats there.
Network usage - While Market, Android System, Google, Calendar are around 1% - .5%, almost 100% of the usage has come from Media. I think this has been trying to keep the network alive throughout the time. I dunno if network means Data or just the voice network. The packages listed under Media are Camera(twice), DRM, Download Manager, Media Storage. Is there any reported issues with Camera or Media Player?
Also, Spare Parts says my Battery Health is Good. Is this a reliable indicator of the battery life?
I believe spare parts receives the battery info via "Testing" which comes stock on android. Let me know how the new battery works out cuz I want to research further when it comes to phone environment versus the actual battery itself.
I have same problem with my battery. I guess maybe battery life since it already use 1 half year. Anyway, who knows.

just picked up a brand new battery today. gonna leave it charging overnight. will report later on whether it fixes the problem with the random shutdowns
... on a side note, i think there has been a battery issue since CM5 correct? in my sig there is a recalibration method by xda member 'my_former_self' for those who have not read it and if your battery is still good to go ... worth a try
new battery
so it turns out my battery issues was in fact the battery. the new battery is working awesome. phone hasn't randomly shutoff on me all day with heavy texting, some youtube vids, mild internet browsing, and several apps ... 17+ hours later about 2% charge remaining. gonna run the battery through its conditioning cycle.
fyi i turned airplane mode on when i was in class ... approximately 2 hours
New battery it is
After spending over 4-5 days with the battery, I pulled out the spare that I had (with a couple weeks of usage) and installed that on my phone. Just to be safe, I drained the battery after some initial charging and ran it through this battery recalib method.
I did this yesterday morning after it being charged fully. I also installed SetCPU after recalibrating. Its run 2 full days of regular usage and I still have over 50% charge left. Ain't that cool or what? I think I will leave it uncharged tonight also and I guess it should last the whole of tomorrow as well. I don't think even the stock cupcake or donut lasted this long on a single charge. So in that case CM 5.0.8 has actually managed to up the battery life a lot (with SetCPU and, sleep on end).
Exactly how long does your battery last? It's no secret that CM5 (and any Eclair ROM) is just plain poor on battery life in these devices, even on my in-warranty Magic it chews through the battery about 25% faster than any Donut ROM such as Dwang, SuperD or CM4.
Seido sell extended batteries which fit in the original phone housing (unlike those ridiculous ones on eBay which have an extended back and turn your phone into a 2001-era brick), they seem to get good reviews, maybe give one of them a go.

Co-sign. I'm using one of their batteries and they work well.
Hi guys
I should be picking up my SGS2 today and I was just wondering what exactly I should be doing with the battery? I've read in a bunch of places that draining the battery fully and then recharging it fully gives better battery life, but I've also read this:
Lithium ion batteries do not respond well to full discharge, you will see reduced capacity and early failure if it happens too often. In any case it is not possible to overcharge the battery on a BlackBerry because the battery and phone have enough intelligence to control the charge (unless the battery is already defective).

(this is from crackberry.com but you get the idea)
What's the best thing to do?
And on Android phones, when the battery indicator shows 20% or something, is that when the phone is going to die? Or will it die at 0%? Obviously at 20% it would be to protect the battery but maybe Android has been programmed to show 0% when the battery is actually at 20%.
Thanks,
Elliott
read manuals !!!!!! You can see this
Did not receive an owners manual with my phone. Anyway...phone is charging now so too late I guess...

The manual is probably stored on the phone, at least my new Ascend II came with its stored on the phone, you have to goto the big menu (forgive me for not knowing the technical term for it) to find it however
i got my battery fully charged...then in the first day i discharged it till 10% at least that's what my phone was saying
i read too that the new li-ion batteryes do not need to be "formated" (fully discharged till the phone dies and then fully charged with the phone turned off) in android case i think that thing is not posible coz it needs at least 5% to pass the bootloader and then begin to charge
anyway in my manual it says that the battery will begin the normal state after 8 days of use, until then it may disschage quick
i have a motorola defy
Calibrate the battery. Charge the phone while its switched off for about 6 hours, and then use the phone untill the entire battery runs out and it switches off on its own. After this, the phone should be able to use the battery properly.
i just used my galaxy and made it empty, then charged it full.
nowadays i have runtimes from 3days (72 hours) and then its @ about 5%
there seems to be a lot of back-and-forth regarding whether or not draining a battery is healthy; i drain my iphone battery down to zero about once a month and the battery has been doing fine for two years . . . whether it would be doing just as well without the draining time is anyone's guess.
I have always been under the impression that lit-ion batteries do not need any kind of special care or break in. But since our phones estimate the charge, we should occasionally let the battery run out to reset the calibration in case it gets screwed up.

I don't think you need to worry about draining the battery till it's dead. My phone dies often and the battery is still kickin It's my understanding, that the purpose of draining the phone before you charge it is to calibrate what the OS says for charge remaining to the battery's actual charge.
Or something like that...
Hi all,
I have my sgs 2 since June and it's working pretty well apart from the battery drain which is very harmful in my daily life
I've recently flashed the Cognition 1.30 (last friday). Before that, my sgs was able to last the entire day before discharging with a moderate use (10-20 mn on games, few sms, 15 mn consulting mails, 1 hr on internet). Since i've flashed with the cognition Rom, the battery drain is really awesome!!!!!!
I fully charge the phone (switched off) then when i switch it on and the phone stays idle, after 1 hr or so, i've already lost almost 20%. When i'm on internet or playing games, the battery loss is approximatively of 1% per min.
I've made a full wipe and recalibrated my battery so normally it should at least last a day and thats not the case.
Could somebody help me or should i buy a new battery and test it ?
Because i relly like this rom and from others users, it has a good feedback concerning the battery use
