HD2 2300mAh EXTENDED BATTERY

My HTC HD2 2300mAh EXTENDED BATTERY shows up as an ordinary 1200mah
I am using Mdeejay_FroYo_Revolution_v._1.7_S6.1 .
Anyone... is it a fake battery or must i do in a certain way to explain to the battery that it is a 2300mah?

Some kernes dont have extended battery support. when the battery runs out, you put it out, put it back in and restart the phone.

Im using the 8.4eb kernel and I'm still having extended battery problems

try 7.7. or I will try to find and see if Mdeejay kernel has support or not.

I think its the battery. 8.4eb supports extended battery.

I'm having issues with the extended battery as well... What did you use to show your phone was only registering 1200 as opposed to 2300? An app?

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

DHD battery life

can someone help me with the battery life on my htc desire hd i want better battery life without dissabling features, thaanks in advance

Well, there are many factors to getting good battery life.
Matching Radio/RIL can be a good start, especially if rooted.
Definitely ROM's also have a big part.
Overall usage will also bare a pretty big footprint.
I get about 18 hours on a typical work day, with moderate usage which is generally enough for going to work, coming home, and then still have plenty of battery left when I'm ready to go to bed, which is obviously when I charge my phone.

Define "disable" and "features".

disable automatic synchronization and shine

+1 there's nothing wrong with setting your Facebook, Twitter, Email, background syncing, weather etc to less frequent but it will obviously give you more battery life than syncing every 5 minutes, common sense really. An app to preserve battery I have found is Apndroid. Have the widget on your home and you can use 3G when you need it rather than not.

I disable automatic sync of all apps. I only update manually when I use them.

if you can echo all the timings I've been disabled, the sync I maualmente when I access the email application, facebook, etc. .. tweteer

have you rooted your phone? which rom are you using? some details will be appreciated...

tried custom roms? i usually get better battery life with them,
also setting off auto brightness helps a lot for me.

Green power free,its amazing my battery lasts at least 60% longer with this app,amazing get it

hey, mate... you've got some very generic question... specific info like ROM you're using, Radio, Kernel would bring justice for members to give you some more specific help.
This probably might help:
ROM CoreDroid 7
Radio 12.54.60.25_26.09.04.11_M2 - (HTC Ace Gingerbread S Generic 2.36.0)
RIL_12.54.60.25_26.09.04.11_M2
Kernel LeeDrOiD GB V3.1.6 - 2.6.35.13 BFS KERNEL (thanks to LeeDroid)
Live wallpaper Nexus Revamp
disabled wifi, refresh, gps (used powercontrol widget for accesibility).
After flashing, my battery was drained in 5 hours even after an overnight full charge.

Cyanideskittle2010 tips will prove really helpful. tweak around phone settings which are my priorities... things i don't normally use disabled them, enabled them when i need to.
also, installed cpu clocking, initially used setcpu, then moved up to cputuner which gave me more options... juicedefender also can help if you prefer it. setcpu or cputuner are both available in market.
gave my phone 24 - 48 hours, after battery calibration, full batterystats wipe, now i am good at 30 hours battery time.
used to have 36 hours battlife but was using CoreDroid 6.7 then... shifted to CoreDroid 7 because i just love its UI.
hope this helps! credits to all xda cooks & chefs, sergio76, coredroid team etc..

the new honeysense 6.0 rom has a extremly good battery life. i wiped the battery stats and now my battery lasts abaout 2 days instead of one

Yeah I have been using APNdroid since Android 1.6 and always have it on my Android phones, battery does last miles longer by using the on off widget to disable 3G when you don't need to be using it.

I'm using CM7 Nightly #108 with LorDModUE V4.5.1 (Killersloth's PUV) and Radio 12.54.60.25_26.09.04.11_M2. Great Batterylife compared to stock rom. I lose only 1-2% over night.

Don't want to steal your post but i just have a question haha.
I ordered a battery off eBay the new battery runs on 1600mAh while the original battery goes on 1230 mAh. Should i worry about battery stats i should wipe after replacing the battery or something like that ?

I think it's better to wipe when the phone is fully charged (test with currentwidget) but i think to best is to use the original battery. It can damage your phone and I often read that those batterys don't have more power than the original.

Is it normal that from full battery after night I have only 50%? Extremely strange for me... I have ARHD 5.1.10, ANDIDA 1800 mAh

i am using ARHD, it has good battery life. Works for me

[Q] 3500mah Extended Battery

Just received a 3500mah extended battery today for my HD2. I have some questions that I'm hoping someone here has the answers to. I am running Android (TyphooN CyanogenMod 7 Nightly v3.6.0)
1.) The battery stops charging at 99%. I've unplugged to prevent overcharging. Is this a kernel issue or something else?
2.) Battery Widget Pro still shows the battery stats of the stock battery I had in before which is 1230mah. I have restarted and cleared battery stats in CWM but still showing the 1230 battery in Battery Widget. What can be done for it to show the correct one?

I might try reflashing the rom today at work and see if that does anything.
Looking at the official extended battery, it looks to be about the same size. Could be a tad thicker, but not sure.

I'm not sure, but, with battery widget, aren't you able to set the mAh manually?

I do not think this battery has really y 3500 mAh. It would make the hd2 even bigger than with the official one from htc.

I was going to but then I saw it has spaces for Max mv and min mv. I don't know how to find that out so I didn't mess with it. thinking it wouldn't work properly without everything set there.

[Q] Battery life very bad on CM7

Hi everyone,
I have a big problem of battey usage on Android...
I flashed the NexusHD2 rom in a first time and i realised the battery life was very bad ! (I lost 3% for 5 minute of use !)
I flashed the famous Typhoon CM7 rom and it's the same...
My Radio is 2.15.50.14 and i use CLK.
Thanks for your help

Try a different kernel. That helped in ICS, so after some trial-error you should find a good one.
Sent from my HTC HD2 using XDA

What kernel is the best for it ?

I use Hyperdroid w/ seader r9 kernel. I get pretty decent battery life with it. But you also have to remember that the HD2 is a bit older so it has a smaller battery and less power-efficient parts.

Agreed, i flashed STOCK Windows Mobile 6.5 from T-Mobile and the battery lasted exactly the same time as with Android on it. I found that the ROM/Kernel combinations only matter a little. The phone alone has horrible battery capacity.

A bit?! Lol that would obviously help a lot. I'm not quite sure how accurate CurrentWidget is, but in terms of standby battery drain I get 5ma drain with wifi on on my phone. On the same settings on my Mum's Desire S she gets 26ma. However she gets great battery life, which I would only guess is due to the larger battery (and the fact that she barely knows how to use the phone, so the screen isn't on very much at all).

I use batterymonitorwidget pro. And i get around 5ma with wifi and cellular on.

Try using an app called JuiceDefender - it works really well at extending battery life. It basically lets you tweak loads of options to do with data and syncing, so you can have it set that data doesnt run when certain apps are open, or data is off when the screen is off, etc.
There's an ultimate version available, but it is £4.99 from the play store. But I guess that'd be cheaper than a new battery?

The same problem occured to me a few weeks ago. I have been using HyperDroid-CM7 which worked quite decent for 5 or 6 months and had very good battery life. ABut a few weeks ago suddenly the battery life became to awfuly decay, wasting 20% of the energy for idle hour instead of the normal 1-2. I changed the rom to the NexusHD2 ICS port and the battery life slightly improved but rhe problem stays the same. Could it be because the battery itself is broken or some software calibrations are needed (I haben't done any for an year since I bought the device)
