Yes, thanks! I've ordered my fat battery from Dave (mdapro uk) and I'm at the edge of my seat waiting for the shipment to arrive...

Had the same problem with my battery, looks like a normal problem on Universal.
Did you ever tryed to play around with linux on your device, this would be very intersteing for me. I am playing with it, and i thought it could be a nonworking linux driver, that distroyed the battery.
So please tell me, how you got this problem.
Hi People,
first of all, sorry for my bad english
Ok, here we go!
I tried to get longer battery life as many other people..
At the End i was at 60% Battery Drain only in 6 hours in the night (when i sleep)
Then i made a complett reset of everything, not only my rom, even more my method i took to save Battery...
I made a first test and it is faboulus!!!
I took the fresh Android Revolution HD 2.0.9 Rom and the RomCleaner.
In my first test i unload the battery totaly 100% _totaly_, then plug in USB -> Reset everything and format everything. Then I removed everything from the Revolution HD Rom Apps like HTC APPs and some other like HTC Facebook, Tweeter, Locations and GMail..
I took the modified Rom to the Phone and for a little bit Style i took the MultiCulti Theme thereafter inside.
Then rebooting, turning on WLAN with key (its always on, when wlan is in range) and plug it off from usb.
As last "step" i took the Phone to my car and charged it with an "Hama USB Cigarette Loader" (He loads the Accu with many more Power, i knew from airplane modells that it is better for the accu to load it with more power)
The Hama loader loads with 2000 mamp and not like the original loader with 500 mamp.
Ok, here my first result after 15 hours:
- WLan always on
- Made 4 normal phonecalls
- wrote 3 sms
- nothing on the homescreens, (but everything installed (with usb plugged in pc))
- turned display to 15% and took a normal Wallpaper with darker colors.
15 hours on - Battery is at 90 %
...hmmm realy n1
let me think... 10% = 15h | 100% = 150 h +/- 10% (for more or less us) = 6 Days
Today, i will start again and make a better modified rom (yesterday i tested only but didn´t think what i realy need and what not.)
I will first stop it when my Desire HD runs 10 Days without charging..
Stay tuned i will be back in some Days
In my opinion, 10 days duration might be able to achive by using airplane mode.
but that make the DHD a dumbphone
Yes, try Airplane mode. My 3 year old iPhone lasted for 19(!) days in airplane mode.

That doesn´t give you more battery.
The dhd has got a s-lcd display all that matters is how bright background light is.
in fact you could end up using more battery with a dark background if you have to set the background light brighter to see something
In my first test i unload the battery totaly 100% _totaly_, then plug in USB -> Reset everything and format everything.

i´m not sure hat you meant. If you wiped everything/installed rom when the battery was at 0%(unload the battery totaly 100% _totaly_) you will mess up the displayed battery %.
the rom you use resets the battery stats when first run. the phone "remembers" the battery power at that time as 100% . while that wont affect the actual lasting time you can´t rely on the displayd battery %
if it´s just a typo nevermind
i wish you luck in your effort
ps.:airplane mode would bring good battery life but shutting the dhd down would give even more time before the battery is empty !!!
If its battery life your after why don't you buy a Johns Phone, google it. The battery will last in excess of three weeks.
That's nothing. I haven't charged my phone for 11 DAYS!! And it will last at least another 6 hours when I switch it on!!!

I dont understand the part I have underlined!
You state that you have used only 10% in 15 hours but you have the phone plugged in via USB to your PC, that would charge the phone!

He was just connecting to USB while installing the Apps.
I guess he'll reach real [email protected]
Atm I think he simply overcharged the battery a little and the battery calibration is broken for the moment.
Lets wait and see. And please stop ranting at him. No need to be rude...
Also +1 for his nickname . Barely spilled my coffee yesterday xD.

Possible cure of battery issues
Ok so at the moment O2 have lost there network ability and I am on stock rom 1.72, and all I have done is turn the Android web browser to enable plugins-on demand. Anyway just returned home from my night shift and the phone still has 90% charge left??? (Phone unplugged 1930).
The reason why I am stating this is because of the Apple Macbok Air issue and flash being installed as it massively drains the macbook airs battery, and Adobe have recently released an update that rectifies this issue.

So, you've got one of the most internet-capable phones on the market sitting on your table, with no data connection and screen barely turned on or what? Not flaming you or anything, but how smart is a smartphone with no data connection? ;-)
How much screen on time do you have in this test so far?

Imposible!
I have data off, flash on demand about month and after 8h sleep time, i have -8% at battery, of course, no display when im sleeping....

I hate the limited battery of the DHD as much as anyone else but honestly, I'd rather charge it once a day or every 18 hours or so if I use it a lot than have settings like mobile data off etc. I bought the phone to use it and the features it has, not to watch battery % and squeeze out more time per charge by turning it into nice looking phone that doesn't get used.
I unplugged mine at 10 am and by 2 pm I was sitting at less than 40% and rarely used it today. I normally get a full day, but today seems it was special
No ranting but just saying i like the shiny stuff on the desktops too, but 3 hours and then problem ahead ....not nice.
I've had my phone for 3 months and just today it messed up. Funny eh?
Hi all (new here..)
Totally agree(with two posts higher). Such brilliant phone with so many nice features, and some people just use it to improve the batt life.
Nonsense.
Use sense.
Use everything that offers. Enjoy it. You'll enjoy more using it at full and charging every day, than saving battery with non usage.
I know i'll enjoy it for 6 months, then better one will come, and we shall all yearn for it. Phones life is too short to bother with energy, after all you can charge it almost anywhere, anytime. Except if you live in the middle of siberian tundra. That is bit annoying for charging...
Just imagine after 20 years someone will read this thread and say: ''Father, you really had tough life back there, didn't you have any of these atomic and plutonium batteries? You actually had to charge them?''
lol

Swyped from my sexy galaxy tab
Guys,
Here is, I do think, an interesting topic about the famous eternal question :
"Please, tell me how to calibrate my f*** battery?!".
To begin with, here are some (fresh) news :
You have to know that our dear brand-new device uses new specific MAX17042 drivers which actually don't allow us to normally "calibrate" the battery as many of us could have imagined.
I quote Entropy512 :
Unlike HTC devices, battery calibration doesn't apply to our devices.
Google MAX17040 for more info - while our fuel gauge chip (MAX17042) does have advanced features that would require calibration if used, those features are not yet enabled and it basically behaves identically to a 17040. Maxim specifically designs their fuel gauge chips to not require special calibration procedures..
Click to expand...

I mean here that using such applications like Battery Calibration (or anything else), or manually delete Batterystats.bin in data/system folder, or even wipe batterystats in recovery, all theses methods are actually .... useless and a waste!
In fact, the only effect you will notice by doing (deleting) it, is that you'll reset your usage stats in the Android battery usage screen. Nothing else, sorry.
The only current way I've found up to now, is to force the internal chip to do it and therefore reset the fuel-gauge.
Here is a very simple method. Keep in mind that's not the only way :
BTW, no root needed here
1. Turn off your phone.
2. Fully Charge.
3. When getting 100% signal, unplug quickly.
4. Pull off the battery and put it anywhere.
5. Wait for 180 seconds exactly (be careful )
6. Meanwhile, take this opportunity to dust off the internal compartment.
7. Put back the battery on the right side.
8. Turn on the phone.
9. Pray the Battery god
10. ... and voilà !
Click to expand...
Click to collapse
After that, you can make some cycle of fully charge/discharge to ~15/20% TO complete the method
I am pleased to share my experience about it.
Hope it could help most of people,
Cheers

Bonjour !
I mean that just be sure to take the time needed to ensure that the chip is no longer powered.

I did excatly what you wrote, 100%, pull out cable, pull out batterry, wait min. 90 sec.
But when I turn the phone on the battery shows only 96%?

Are you sure that you have fully charged before unplugging ?
Anyway, If you had well done, just use normally your phone to notice if battery drain is correct, and do a cycle of charge and discharge.
BTW, after doing this method, my battery shows 100%, so I'm sure your battery wasn't 100% fully charged
Yes I'm sure I got the 100% pling the first time.
Charged from 96 to 100 again and did the procedure again and got 100%.
Btw.
If someone knows the max. (fully charged) capacity of the Samsung original 2000mAh pack in mv (4192mV ?) and min. when the phone turne itself off (2800mV ?) I would like to know.
The values will probably be different from packs to packs but approx. values is ok.

About the 96% battery charge it's a known Galaxy SII problem, which has never been solved.
Sometimes you charge to 100%, and sometimes 96% (hiden right after a 100% charge).
You must live actually with this if you want to continue the adventure with your SGSII

I am using "old" official 1650 mAh battery, and max capacity is 4202 mV for me
So, I think you can consider it's about 4200 mV.
Like you know, i've put the new checkROM on my device. Should i calibrate your way before restoring my backup or after ? Does it matter ?
Merci

AFAIK, it doesn't matter at all, just make sure that you have restored good files (2.3.5 with 2.3.5 ones)
After running TitaniumBack Pro, you can calibrate your battery if needed, then enjoy this amazing ROM !
That's exactly what i'm going to do !
Super !
Moreover, If you did a full data wipe, there will be for sure zero bug
Waiting for new themes tomorrow, specially for black and white ones.
I'm so trying this

It will be so useless
What do you mean by that?
It is recommended to calibrate your battery every time you change your rom (after).
There are some apps in the market but you need to be root.
With this system no root is needed.

I've had this happen to me before, I had to do a full reboot then it would start charging properly.
So i will get the phone on Tuesday, do i need to charge it overnight first before using it?
Is the "thing" still apply until now?
Or
After i receive the phone, and i can use it immediately ? Like, installing my apps, playing games at the same day?
Or maybe i need to charge it to 100% first?
Maybe discharge with some task to 0%, and charge it 100% without any distrub?
I'm still curious..
I still need some answer, or maybe what u guys did to ur phone
I think discharging to 0% and then charging it to 100% would prove to be the best options

If you plan to use the phone less than 2 years you can charge all the way till 100 and drain till 0.
And if you plan on using it for a long time(>3 years) keep the levels between 20 and 70.
