If ur able to use android with ur extended battery, then the kernel patch is doing its job and is already "activated". If it weren't, you wouldn't be able to load up to a launcher.

That's what it is suppose to do because it's not fully supported I guess. When it dies (at normal speed) take the battery out for like 5 seconds and then put it back in and turn the phone back on. It will boot up with ~60% battery remaining.

The code being used is from hastarin and is in beta.... Wait, are you using the 2400mah battery, and not the official one?, if so, then it's a known problem, and none of the kernels have support for it.

Yes, I assume it only does it because the kernels are supporting the official 2300mA one; but if his is doing the same as mine, I'd imagine he has the 2400mA also.

He doesn't have an extended battery, he uses data from the official battery users to modify the kernel to support it. PS. there are other threads mentioning the same problem about this type of battery.

I was referring to the OP having the 2400mA.
You do know the MDJ 7.5 doesn't support the extended battery. You would either have to downgrade to MeeDJay Froyo HD 4.2 (which supports the extended battery) or do a kernel upgrade to MDJ 7.6 (which also supports the extended battery).
Speaking of the extended batt and MDJ.
I had a weird readout on the Leicke 2300mAh one which I believe might be identical to the original HTC.
It would drop 10% the first 30 min with no ussage at all. It would show 10% left at 3.75 Volts or so.
I just installed MCCM_HD_V2.0 and hastarin_r8.5.1_eb. The readout seems alot better now. Now it is at 3.921 Volts and showing 83%
I dnt ave the orginal battery

i am not use the official htc battery i bought mines frm amazon or $20 2400
Use hastarin 8.5.1eb, MDJ's ext battery support isn't there yet. I tried his 7.6HD and wasn't reading my battery correctly at all and it was dropping 1% per minute. Under 7.6, my battery read 73%. I switched to hastarin 8.5.1, and the reading was 90% which was the same reading as it was in WinMo.

I second that. Try Hastarin instead of MDJ for the extended batt.
Mine is at 71% now where as with MDJ's kernel it would show around 10%.
thanks very much for ure help guys
there is a rom or kernel for extended battery?
would be good for those who have

Are you sure of that? I've been known to be wrong before LOL, but AFAIK the current kernels don't support EB and the rom just boots and switches itself off. Are you running with an EB currently on a NAND build? It will be great to get confirmation that it does indeed work as I'm currently telling other users that EB is not supported yet.

Some of the kernels compiled by others do not support EB but I've got the "original" nand rom booted on a cheap ebay version....authentic one purchased but won't be here for several weeks so can't confirm about the E400.
mdj has support?
Maybe I use the cheap EB from eBay, not the one from HTC

Not yet, supposedly the ones with hastarin kernel at least let the rom boot fine, but I can't confirm since I left my extended battery in another country and am waiting for my family to send it back to me

AFAIK 'Official' EBs need the special Kernel to boot, knock-off ones don't, you just get wrong readings (die in normal time, pop battery out, put back in and have 60% left) --- I have the 2400mAh Ebay-Knockoff and can confirm it working with any EB or Non-EB kernel.
Nand not compatible
Tried Desir HD ROM's, desire ROM from cotulla and none are compatible with eb.
it boots until lock screen then re-start from begining....
on the other hand...
NAND drain less battery than SD builts....

On a normal Desire build the extended battery would of course work out of the box but EB support has not been a priority for the developers...especially since most don't even have EB's.....in their defense they were busting tail to get nand working and then look at all the nice stuff the bootloaders and clockworks gives us so I am in NO WAY complaining.
The problem is...to add in office EB support they have to take an OLD eb driver and future port it to work with the new desire battery driver.....and no one has been in a rush to do that cause it's NOT a simple process...in the most recent hastarin kernels he had some up with some version that would support the EB but his kernel was PPP only and many of the nand ones are using RMNET again....so...for now you have to bide your time and wait for a cook who actually knows enough to do more then grab the latest GIT code and compile it. Someone like hastarin or cotulla who can actually apply the driver, make required changes and test it out....which means the cook also has to have an offical EB to test with...hastarin got one a while back from donations but I have not seen him posting in the nand forums.
Lastly....you can't just install magldr, play around with nand and then boot your old reliable SD Build from magldr...for whatever reason they will boot and then promptly freeze at the lock screen probably looking for driver support which is not there...so it's kinda an "all or nothing" thing once you decide to "go nand".
mdj's nand rom doesn't support e400.
hope there will be one soon.
Apparently tytung release a kernel for extended battery check out his post...but I can't get it to work
Hastarin's kernel DOES semi support EB... as in it actually lets you use the phone with the official EB...
only problem being it charges to 60% then goes fully charged... similarly it drop from fully charged to 60% in about 20 mins..
apart from that it works....
will do for now untill the EB issue is properly addressed... unless we have to wait for an "official EB from HTC for the Desire/HD/Nexus.

His kernel is hastarin's 8.6 re-built, it allows to use official EBs but kills the camera.
So it's close but not the solution.

In comments made by hastarin in his sd thread I believe the desire DOES have an extended battery but it's NOT compatible with ours which is why a different driver is required....the normal battery was fine but the EB wasn't when they ported the desire battery driver over but since it gave better support for regular battery then the previously used one they went ahead and used it.
Tytung's Kernel (works for me (not too well), but I'd recommend using the normal battery): Kernel

Not entirely true, it charges full, it only "seems" to charge to 60% because the first reading is read as a stock battery, (it'll 'die' just as fast as a stock battery after fully charged) then all you do is pop the battery out of the phone for like 5 seconds, put it back in and boot up and then you have the remaining ~60%. It's annoying...but it does work.
But as someone stated, the Desire builds actually do (in a sense) support the EB all around, atleast the unofficial ones. It'd charge mine full then drain normal speed to 15% then stay at 15% for hours and hours until the actual EB was at 15%, then drain till dead and actually be dead.
I have an Unofficial 2400mAh EB and have never had a problem (they work with Non-EB Kernels just as well as EB Kernels), the only thing is only Desire builds let you drain the entire battery without reseating the battery.
---Official EBs are another story however, they actually do need an EB-Kernel due to drivers.
2600 mAH Battery Test
Just plugged in a 2600 mah EB (Hongkong) battery and booted. It has booted and begun charging ok. Will post usage results.
Using Clean Desire prj 0.2
I bought an extended life battery at 2600 mah for the HD2 running darkstone's superram 1.5. This is almost twice the normal battery size yet my battery life seems to be the same. Is their a problem with the battery or should Android be somehow programmed to recognize it?
me too, im using typhoon cm7

No that was my point, some kernels will support unofficial batteries but not official. Something from arne should work, I know he has made some 2600 supported kernels.
You can also try the newest rafpigna or tytung kernels. They also have the eb fix with them, credits go to arne.
I understand that there is no firmware to support the official extended life battery?

Guys i need you help!
A few days ago i stumbled to a cheap extended battery for HD2 and i bought it.
Unfortunately i just found out that most Android NAND ROMs dont support it....
Can you please point me to a ROM build that does support it?
Its a non-HTC 2600mA battery....
Currently im using CoreDroid 1.6 and its draining my extended battery just like a normal one.....
Thanks!
extended battery support is kernel related, not rom related.
every rom which is using the current tytung or rafpigna kernel supports extended battery, so my guess: nearly every rom out there

Why is it draining my battery so fast?

how much have you used your phone? if there were a few calls, a lot of music/games/whatsapp/whatever its perfectly normal.

Not much.
I used like i use it normaly.
A few cals during the day,couple of texts and a few minutes of internet...
My standard battery usualy lasts 24-36hours.
I thought extended battery would give me 2-2.5x longer battery life....
I read somewhere that when battery level reacher zero extended battery users should restart the phone and it will go back to 60%....
I wonder if Android can even charge extended battery to 100%?
If the battery you bought is a non HTC battery then it may not be what it is advertised to be, ie not the ma that it is supposed to be, you hear many stories of cheap or 'fake' extended batteries

Get "Battery Monitor Widget Pro" and that tells you what mAH your battery is and that way as its non-htc you will know if its genuine, i bought a non htc battery apparently 1600 mAH when i first got phone but had no idea back then and only until i got "Battery Monitor Widget Pro" it told me it was 1230mAH which is the original battery so i just use one as a spare now and take 2 out with me, so i can drain it as much as i want, as i know ill never be without
Ok,here's what i did.I let the phone discharge to 50% thatn i powered it off and took the battery out for 10 seconds.
After rebooting the phone battery level was 78%
Im guessing that rafpigna kernel can read extended batteries just not entirely correct.
I'll wait until phone discharges completely and will take out and reboot again.
I tried Battery monitor widget and it reports 1230ma....
When i finish testing i will report back.
Hi! I wanted to know if you guys have a problem with the battery life on SwiftDroid RC5. I have a poor battery life and therefore big battery problems.
i had mine and bought a new batt no probs after that
Yes, I do. Since RC4 and RC5 I have very poor battery life. Before it was enough to charge once every other day, now I have to do it daily.
Actually after installing RC5 it was a disaster as battery didn't keep even 24 hours but after recalibration it's better. But even then during the course of the day while doing basically nothing (say, sending and receiving 3 or 4 sms) it goes down from 99% to 40%.
Edit: I should mention that I overclocked to 800MHz, but I used to do it before RC4.

Same here. I'm moving on Cyanogenmod 6.
yeah swiftdroid is a real battery drainer but
on swiftdroid on average my battery lasted 2 days..
but still i use cyan6!!
good in battery and performance!!
Same here. Experiencing battery problems on SwiftDroid aswell. Like mentioned above the battery drains even when doing nothing. Experience this on basically any mod built on SwifDroid ofcourse. Changed to EleganceSwift, waiting for mike to release AOSP with Bluetooth-free radio ;-)
There's something more to it.
Recently I was playing a bit with my phone, installed couple of applications and then suddenly I realized that battery doesn't drain as fast as it used to. One thing I noted is that for example Videos application doesn't reside in memory anymore. I'm not saying this one was the sole battery hog but I'm starting to suspect that those cases of battery going down very fast may be related to some misbehaving app or apps and not necessarily be Gingerbread's fault.
If that's the case, the solution would be, I imagine, to trim system preferences to have such apps killed fast not to let them stay active.
using ASIS atm, but when I was using RC5 I didn't notice much faster draining. Still, it depends how many apps are running on your device and did you overclock it? I used to have min 250MHz, max 600MHz and it was pretty fine with texting, multiple apps running and music. Now with min 825MHz/max 825MHz it's draining faster ofc
Well,I remember a day when i update to SwiftDroid RC5, the batter drains and there isnt any app running in background after that i changed to a another rom.
btw fdespotovski, Multiverse is my favorite rom, in fact, i wrote on the offcial blog but i have problems with the RC3, statusbar sound widget doesnt work properly for now im on RC2

I'm not using ASIS, still at RC5, and what I reported is that both RC5 and RC4 drain battery much faster than earlier versions. Assuming ASIS is just cosmetic change to RC5 it doesn't surprise me you didn't notice any difference. And again, I do overclock to 800MHz and I do it since M5 if memory serves me well. I know principles of overclocking and I know, and accept, drawbacks that come with it. But when at the same clock RC3 can live two days or more while sometimes RC5 barely manages only one then I suspect something is not right.
I tried to check which applications are responsible for battery drain but system report is not helping when telling that 98% took Android system, 2% cell standby and 2% phone idle.
Sorry for necroposting but I didn't want to litter forum with new thread and the problem itself hasn't go away.
I'm still using SwiftDroid v2.0 RC5 and until recently I still had problem of battery barely keeping one day: whole night on the charger and after moderate to no use during the day on the evening it was almost drained.
Recently I installed one more application (rather unrelated, I'd need really solid proof that CPU Spy directly improves energy usage) and after that the battery easily keeps for two days. Which brings back the theory I have that the short battery life is not necessarily caused by Android itself but by some applications staying in memory and not sleeping properly. If so, installing extra app may help just for this reason that it having higher priority will swap out those misbehaving ones.
Thus I propose little hunt, if anyone's interested. I'd like to stay focused on v2.0 RC5 (maybe RC4/ASIS if you believe the difference is not too big). I need reported both GOOD and BAD battery life. In either case please write down all apps currently in memory (you can skip those you have installed, I'm mostly interested in what comes from ROM). And don't forget to mention which actual version do you use and whether it's good or bad case.
Given some meaningful data I hope to isolate which apps cause excessive battery drainage. I'm not sure what to do with that information next but I think it would be good start anyway.
To make said start, here's what I have:
SwiftDroid 2.0 RC5 / GOOD battery
- DSP Manager
- Usage Timelines Free
- Doit.im
- K-9 Mail
- Auto Memory Manager
- Superuser
- Settings
- TM World Clock
- Go launcher EX (doesn't report itself as staying in memory but I suppose it has to be running somewhere)
