Today i recived an extended battery , i unboxed it and then i replaced it with the one wich i got it with device, then i start my device ,run haret all things were cool till my UI start , then my device vibrated and then gone off tried with 2 builts :mattc Leo Froyo Sense 1.6b(used fresh built because the old one that used with old battery didnt work) and shubCRAFT_1.4c(used old built wich have used with my old battery)
Any solution?

I have extended battery to, not read around for a short while but drivers are needed for extended battery's to work I remember reading a thread saying someone is working on them but not heard since so +1 on that

There is a kernek that allows using extended bttery. However there is no temp monitering so its not recomgded to chargw in android

This is still being worked on throughout the builds.. i had the same issue.. but yes it is a driver related issue due to the temperature being misreported.. so it freaks out and shuts down the phone..
A work around apparently is to cover the middle terminal of the 3 on the battery with some insulation tape ( i think it's the middle one but cant remember which post it was in..)
I havent tried this personally, and wouldn't recommend doing it really but some other people have tried ...
Patience is a virtue

On a positive note, with the extended battery you can fry up some delicious flapjacks on your phone while playing Doodle Jump.

Moved over to General

There's now a kernel that fully supports the extended batteries!! I'm using it right now and it correctly reports battery% and temp. I charged my extended battery last night inside Android and it worked without problems...

Extended battery

Several people have stated that some off-brand extended batteries works with WP7. For those of you who have them could you please link me an ebay or amazon page so I can buy a few?
I've tried the HTC authentic extended battery and the 3800ma battery from ebay and both don't even allow the phone to boot into windows, but work fine in android.
a battery 'case' would also work?

Dont look pretty

thanks. ordered

i dont know about anyone else but my device will not detect a battery larger than stock. I have 2 a slightly larger 1350 and a 2600 and both report as only ~1230

a friend at work at the 2600 and it did not say it was larger using battery tool, but so far as lasted 2 days and is still in the 80% range.

The HTC 2300mah battery boots fine on wp7

I have the HTC extended battery (with kickstand) as a backup to the slimmer stock one. But when it is low, WP7 doesn't recognise it and wont charge it. That is, I put the battery in, start WP7, plug in charger- the top LED alternates red/ green and it doesn't charge. Luckily I have dual boot with magldr and android and can charge it that way and then it runs fine on WP7. I remember in win6.5 there was an upgrade to handle the extended battery, does anybody know if I am damaging the battery using android or WP7?
Seems from other threads there are similar probs: this from jaze33
"there is no official EB support in this rom. i have a HTC EB and it will not work. I also have non-official EB from ebay and it works great. we will just have to see if the dev's put this into the kernel or something to support it in the future."
Thanks all

Extended Battery charging issue !
Hi Guys,
Anybody with a solution for this extended battery charging problem on HD2 with WP7 ??
Seems to pick up charge in Magdlr mode, but don't know if the phone will detect the correct battery capacity after charging ?
don't see a solution in sight for this lingering problem.
Any help ?

hi,
I've got the original htc extended battery with 2400mAh and with Android it works very fine,all work...
So i want to try WP7, but i don't want to miss this extended Battery, so works it with the DFT UltraFruit Rom or is there a wayne that it will work or is it a kernel/something other problem?
Thanks a lot

Hi Verita5,
Which android ROM r u using ? Is it on an HD2 ? I would love to try out a ROM which recognises the 2300 extended battery and charges it normally to full capacity.
If it works, I would make my HD2 dual boot with Android & WP7. It would be at least better than my present method of charging my ext. Bat. only in Magldr mode, during which time my phone is useless. My WP7 ROM does not detect the original HTC ext. Bat.
Awaiting a reply.

SE Stock Rom Advantage!

Hello All,
I noticed there are a lot of posts regarding Battery Usage & Optimization...
I tried many many combinations of custom roms, basebands and kernels and I always face the same battery problem especially when 3G/MobileData is switched on.
I admit that Sony Ericsson gave us a ****ty stock rom with poor kernel however It's still the best rom in managing battery usage.
I made a small comparison on Stock rom VS Custom roms with 3G/MobileData left switched-on and I found the following:
Custom rom(s): battery drain down very fast it goes for 100% to 1% in less than 8 hours (normal apps installed)
Stock rom: battery lasts for 2-3 days with normal daily phone usage (same apps installed as i did in custom rom)
Please share your opinions.
Thanks,
Ayman

I don't agree at all...
Custom roms can have just as good, if not better, battery life.

I personally think this was a good idea. Nice post and info. Just curious, how long did you do this study with the data you got?

hey guys, i too have this issue, i dnt know if its device specific. ive had the phone since march(2010) last year and have been modifying it with the great mods that the devs hav given us. everytime i install a custom rom i just get unusual battery drain, like yesterday, i followed instructions to the letter and installed tripnravers miuifroyo 1.0.8 and i lost 10% battery in like 20 minutes n ive hardly used it :-(. so nowadays i stick wiv a modified stock 2.1(ewjet to b exact). im gna buy a new battery and see if i get the same results. i really wna use a custom(2.2+)rom but the battery problems are really putting me off, theres so many people out der that arent really having ny battery drain whcih jus dus my head

Thanks Voelker BTW this is my first Thread in XDA, I used to use SE 2.1 stock rom till the first stable Froyo custom rom came out. I switched to Froyo then I started to notice this around 4 months ago and I tried many combination and a lot of optimizations to find out the best one although Stock rom was always better.
@fiscidtox:
I love Foryo and GB much much more than Eclair I currently on CM6 v6 Wolfbreak
Could you please tell me how the battery lasts on your custom rom while MobileData is left switched-on?
Thanks,
Ayman

I get a full day..
If you mean stock with no tweaks then maybe it would last longer, but a lot of that would be not having jit enabled...

You must be doing something wrong!
10% in 20 mins isn't normal.
I'm sure if you left it settle this would rectify itself though.

I think the biggest advantage of the stock kernel so far is stability, but the ongoing development for the custom kernel is sucessful to implement some problems such as battery drain caused by unability to go into deep sleep etc..

I never understood needing more than 24 hours on a charge. Charge it while you're sleeping you wont be using it then anyway.

Even if you like the 2.1 Stock ROM for any reason (Stability,Battery,etc) and don't like all these awesome 2.2 and 2.3, you should at least use Eric's JET ROM which is based on the original ROM has no stability issues and has faaaaar better battery life.
But seriously, I`m using Custom ROMs since the first 2.2 ROM by Z and never even cared to get back to the stock ROM.

When I use Wifi custom roms have almost the same battery life as the stock rom. But since I can't connect to wifi at work on any custom rom, im forced to use 3g.. and I need to charge my phone twice a day with almost no usage.

why not only connect to 3g when you are using it?

I have it set to switch to 2g when the screen is off (I need it on all the time for IM )

can't wait till gingerbread comes out. if the performance is like the arc then I will just stick with the stock rom.

Let it settle for at least two days to see improvement.
Your battery needs to adjust, much like letting your phone build a cache, in order to really see how the rom will effect anything.

Im using the stock rom and my battery lasts a maximum of 2 days with this tweaks: http://forum.xda-developers.com/showthread.php?t=934486
I dont use 3g at all and i use wifi sometimes (session lasts only 10 mins or so)
Brightness is set to "middle" also

Sorry dont agree..
I use wolfbreaks latest rom with the undervolt module.
Juice defender only enables my wifi when i am at home...all other times i have data on with facebook sync.
I now get the same battery life as i did on stock 2.1
Currently I have been unplugged for 1day and 12 hours and I am still at 38%.

3g is useful incase of using Apps such as viber, whatsapp, IM and Gmail as it makes you online and reachable all of the day.

Honestly I didn't try the undervolt module with wolfbreak's rom, I thought It was developed for stock rom only....I'm gonna give it a try and I'll be back to you with the result.

[Q] extended battery rebooting

i have a hd2 which was on WM6.5, i installed the nand version of android and found it was eating up the battery a fair bit. i bought a extended original battery from ebay and found it kept on rebooting my phone straight away, the seller sent me another one and it done the same!! i tried the standard battery and all was fine, i then tried a extended battery from china that worked really good.
is there any reason why the original htc extended batteries wont work unless both are faulty?
any help would be great,,,, many thanks

Maybe you will have a look on this thread: http://forum.xda-developers.com/showthread.php?t=898818.

You just need to use a kernel which supports extended batteries.
The tytung kernels posted in the following link support it.
http://forum.xda-developers.com/showpost.php?p=10429937&postcount=3

many thanks to you both for all your help, i thought i was something i had done or had a faulty HD2. i will go and try the modified kernells, many thanks, dave.

extended battery 2300mAh

Is there a rom that works on an extended battery 2300mAh ? I apologize for my language

Why it should not? Extended or external?? Did you try any?

Battery 2300mAH
When charging the battery 2300mAh flashing orange and green. Does anyone know how to remove this error?

Im not sure of anyone who has gotten it working to be honest
it either doesn't charge it properly or doesn't charge it at all...
at least from my experience.
External chargers are the way forward but they don't help the OS thinking its running low on juice when infact its only half empty... I have a 1360mAh that's detected as such in WM but comes up and only users 1250 or something on WP.
the battery is all a bit of a mess to be honest

i buy cheap 2600 mAh battery from eBay and work fine....
but every time when battery drop to 30% must restart device to refresh battery indicator to 50-60%....

Baterry 2300mAH
And what radio and rom you use?

2.15/5.15, rom you see in signature....
but with v7.5 i have 5-6 days battery life, with 7.9 2-3 days max if have luck

Dxdy...i found that 2.12/5.50 is da best combination...actually what is the best combination can u tell me? Do u have the radio 5.15?i need that to test on my Hd2...can u provide me any link

sorry write wrong.... best combination is 2.12/5.51 or 2.15/5.51 with radio trick
only with 2.12 data and wifi connection is slower

Baterry 2300mAH
Will test it, I hope that it will charge the battery 2300mAh

i have tried all the combination so far
2.15+5.51t
2.15+5.71

the problem is radios were developed based on Network and location, just because one radio has a high version number doesn't mean its better.
So 2.12 might suite one network but not another.
Best way is to try them, hardwre hardio is dead easy to change anyway, the software radio is slightly more of a pain in the arse to trial

It did not work. When charging the battery LED flashes green and orange. I do not know what's error :-(
