Hey all-- just bought a 2400mAh extended battery. Will there be any kernel issues due to incompatibility or whatnot? Are extended batteries supported?
there may be problems. Some kernels do support extended batteries though, just read the opening post as the chef usually says yey or ney.

The 2400mAh works fine with and without EB Kernels, only Official Batteries require the EB Kernel due to drivers.
I can confirm the 2400mAh Ebay one working with and without EB Kernels, you just have to take the battery out and put it back in when the phones dies (It'll drain just as fast as a normal battery, then you take the battery out for like 5 seconds, put it back in and then start the phone up and you'll have 60% or so remaining)

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
Sent from my HTC HD2 using XDA App
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
I found several 1600mAh batteries on ebay, which have the same size as the standard battery.
I found some threads reporting that this kind of battery seems to work with WinMobile, but I'm not sure if it's going to work with Android.
Especially after there is always a discussion about kernels supporting extended battery or not.
So here's my Question: Does anyone if this kind of battery works with android?
-> [yes, but only with a kernel supporing EB]
-> [yes, but only with a "normal" Kernel]
-> [yes with every kernel]
-> [no]
Thanks for your answers in advance!

I have one of them
It last LESS then the original battery, I think they are crap
Anyway normally EB kernel support the "official" extended battery, but you may ask Arne that is developing an EB kernel based on mine to see if it works or not with the "cheap eb"
Anyway, as a personal suggestion, if you want more "juice", buy an official eb or dont buy that fake eb
I recently bought a battery by Andida from eBAy, which holds 1600 mAh. Even though it works with Android (NAND HyperDroid, latest version) I didn't notice any increase in battery life. But it's a good spare battery, since I only paid a total of 15 bucks including shipping.

thanks for the answer! Did you wipe your battery stats?
Here is what I wanted to do:
Use this battery for 3 or 4 charging cycles until it reaches full capacity, than wipe battery stats and see how long battery is lasting then...
Anyway these batteries are cheap, so if they last as long as the original I just use it as a spare battery...
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
Have you checked to see if the included kernel supports extended batteries, official or unofficial???

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?

I respond to you now whilst using the official extended battery, just ticked over 11 hours since charge with light to medium usage including calls YouTube, here, several apps games, 74% left, you sir I challenge to a dual about your understanding!!!!!!
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

Well...CoreDroid 1.6 uses rafpigna 1.9OC kernel.....
Why is it draining my battery so fast?
I charged it to 100% at 16:00,now is 23:30 and its already at 65%.....

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
Sent from my HTC Sensation Z710e using XDA App
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.
Hello, my s4 mini is shutting down still having a lot of battery. Like when i turn it back on it still has 74%, more or less depends when it shuts down. The battery is new.
I think it might be a software glitch associated with a bigger battery upgrade that my phone can't figure out.
Does anyone know how to deal with this problem? :angel:

I think the kernel needs to be modified, though not sure if newer custom kernels support this nowadays as I have never used an extender battery.

I thought about the kernel too, but i couldn't find any related to battery expansions.
just a hint
sorry i cant provide detailed links or such. though i can confirm the rom has to be modified. there are some topics buried in this forum here. you have to dig. i decided to not use non-standard batteries on the serranoltexx because of the fuzz about it to get it working...

I remember there were some topics about this, but there were only kernels for the stock kitkat version i think. I am using the official lineage 14.1 version and i wish i could still use this rom with the new expanded battery and not having to go stock for it.
stock and extended battery...
is there any evidence that the stock-rom/kernel is supporting extended batteries?

I couldn't find any, but i'm a bit pissed that extended batteries even exist for this phone if the phone's software is limited for the stock battery's mAh.
well...
indeed! where is light, there is darkness... imho 95% of the customers buying these batteries dont even know about the hardcoded data of battery inside the kernel... this is weird isnt it?
