and when is this temp mesured? During load, Idle, or charging?

I have a total of 5 aftermarked batteries with 2 more on the way, all for the HD2 all claimed to be in the range 1300mAh - 1600mAh.

During the next week i will do some more testing of these batteries inc. the original one and make a larger thread with test results. What test does ppl want to see?

At this stage i have decided to go with the following:

- Charge battery out in device, then mesure how many mAh i can get in them before they are fully charged, should give a good picture of the capacity. (Repeat the cycle a couple of times to look for changes)

- Test video playback from 100% to shutdown. (Flightmode turned on and same video file ensures that the test is the same for all batteries)

- Temp readings both Idle, Charging, and load.
[HD2 Accessories] SMS92:
i look forward to your findings :)

im looking at purchasing a second battery for my leo so your results will be of good interest to me.
[HD2 Accessories] the7thson:
This would be a great test. Please make sure that the screen brightness is identical and the exact same services/radios are on eg. phone on, data connected, bluetooth off, wi-fi off etc.

I just got my HD2 and and I'll be looking forward to your findings!

Thanks a bunch.

during idling. stock battery temp is 31-33 . aftermarket as stated on previous post 41-43. 10 degree is serious huge.
[HD2 Accessories] A|ex:
I go HK several times each year and the batteries you buy of ebay depend on the seller. Some will be fake some will be real, only the seller will know.
[HD2 Accessories] Eggy88:
Will do some test regarding this as well. Have a IR temp gun that will give some accurat readings.
[HD2 Accessories] kilrah:
I've found that the batteries don't actually overheat, they don't even get any warm at all, but it's the temp sensor inside reporting erratic values, and the phone thus stopping charge for safety.

My 3rd party ones sometimes don't charge, but start after a moment or after I disconnect/reconnect the charger. And actually right now it's my original battery that's not charging. And it's cold.

Sometimes moving the battery a little (to improve temp sensor contact) helps.
[HD2 Accessories] Chrisuk80:
I bought the same Ecell battery, 1350mAh costing me £7.99 but when i use tbattery in the Full (mAh) box it reads the same as my OEM 1230mAH battery

also with the Ecell battery i cant use my phone when its charging or attached via USB as my HD2 overheats but does not with the OEM battery

then I bought a 1600mAh for £5.99 and all seems fine except again when i use tbattery it reads as a 1230mAh battery!!

anyone know of any app i can use to read the capacity of the battery but not just in %, but in mAh
[HD2 Accessories] Eggy88:
I dont think that is possible unless its a program that loggs all the power consuption and then uses that to calculate the capacity. All the programs i have seen uses the integrated Battery driver (Or something like that) and since the stock bat is 1230mAh, that is what all other batteries will show as.

Maybe i'm wrong but that's my experience.
[HD2 Accessories] .hide:
Imo the link u shown , ecell is the one i am having too. its work better then orginal battery , for me at least. but too bad its not going to charge on device itself. since you tested the 1600mAh which i am pretty interested earlier on. care to share the battery life?

between how is the other 2 china battery, is it able to charge on device itself?

I am hoping its a ditch on the temp sensor which cause after market battery not to be charge , because as stated the device is not anything near warm or hot.so it cannot be 40+ degree.

[HD2 Accessories] kilrah:
Didn't you see the one on the left?
[HD2 Accessories] Eggy88:
All the other batteries are charging in the device, except the Ecell. The 1600mAh, has show to be about the same as the original 1230mAh battery.

[HD2 Accessories] noofny:
Have been reading all over about battery alternatives and there's quite a bit of interesting chatter going on and plenty of peeps saying they've ordered a battery, but there's very little hard reports from anyone saying it is worth it.

Can anyone who has purchased an alternative battery and noticed more than say 10-20% improvement speak up please?

Cheers ya'll.
[HD2 Accessories] Eggy88:
As i said erlier, at the moment i have 5 batteries in addition to the stock, with another 3 on the way. I will post a larger report thread here on xda with several test of all the batteries. I thought i would have the other batteries by now, but looks like easter is delaying the shippment.
[HD2 Accessories] rickyoon.vegas:
Bought 1600mAh Andida battery.

tBattery shows the full mAh as 12296. what is that.
[HD2 Accessories] jamieeeee:
its a known fact that '1600' battery is only as good (at most) as the stock one :(
[HD2 Accessories] rickyoon.vegas:
Yes, but at least now I have a spare battery.

I was just asking what 12296 meant.

does that mean 1229.6 mAh?
[HD2 Accessories] Eggy88:
Yes that means 1229.6mAh, but as i said earlier this number is not correct. Out of all my 6 batteries all show up as this, and IMO this is not possible. Even between two original batteries there will be some difference.

I think that programs such as tBattery uses the battery driver in the HD2 to "read" the capacity, and becouse the original battery is 1230mAh this is the number that the driver gives out.
[HD2 Accessories] 3to4:
Hi,

I got 2 Andidas (1600mAh) and 2 Galilios (1500mAh). It seems to me that the Andidas last as much as or a little less than the original battery, and the Galilios last much longer.
[HD2 Accessories] Eggy88:
I also have a couple of the Andidas and a Galilio, have not tested the Galilio yet. But the Andidas has shown to be close to equal the stock not better and no worse.
[HD2 Accessories] efjay:
Hi, how much longer would you say the Galilio battery lasts vs the original battery? Any problems charging in the phone while its on or do you use a separate charger? Thanks.

@Eggy88: did you buy your Galilio from a private ebay listing? Seems to be the only one selling them.
[HD2 Accessories] Eggy88:
Yes it was from a private ebay listing. I have problems charging it in the device, so do alot of other guys. Charging it in a seperate charger workes great.
[HD2 Accessories] efjay:
Thanks for the feedback, that rules that one out as charging in the phone is crucial for me.
[HD2 Accessories] 3to4:
Hi,

It is not easy to say how much longer, but the charge goes down from 100% to only 80% after 24 hours. (But, I used it only for a few calls, and a little wireless. That's all.)

In my case, I have no problem charging Galilios (and Andidas also) in the phone while it's on.
[HD2 Accessories] cedrikk:
With the original battery, we're standing 4 days, almost 5 days to plug the hd2 (with phone/sms only)
[HD2 Accessories] Shadowdh:
I might look into one of the Galilos... where is the best place to buy them?
[HD2 Accessories] efjay:
Interesting that you have no problems charging in the phone. Are you using the original charger or USB cable? Is that a full 24 hours and do you feel that is an improvement over the stock battery? Sounds like an improvement but my usage is pretty heavy most of the time so I cant remember how the stock battery fared last time I used it minimally. Thanks for your feedback.
[HD2 Accessories] 3to4:
I use the original charger. I use also a third-party usb charger without problems. I do feel there is an improvement over the original, which used to go down faster, it seems.
[HD2 Accessories] efjay:
Thanks for the info, ordered just the battery, if it has problems charging in the phone I will chuck it as I dont want to be removing my battery nightly to charge it.
[HD2 Accessories] Eggy88:
Finaly got all my batteries (total of 7 inc original) so i will try to get the time to do some testing ASAP, between all the studying, work etc)
[HD2 Accessories] the7thson:
Eagerly awaiting your results :) Thanks for doing this!
[HD2 Accessories] Diablo2424:
Nothing from Eggy88 yet on the batteries? I'm waiting for his review to make my decision on which one to buy!
[HD2 Accessories] Eggy88:
Still testing, but not easy to get the time to do this. I have a fulltime job (40 hours a week) in addition to 4 examns coming up the following month, so please hang in there.

I think i will have the time to get this done within the week.
[HD2 Accessories] reflux:
decided to buy a galilio battery that came with a battery charger. cant wait to test it out
[HD2 Accessories] EightEight:
Andidas and Galilio which one should I buy? Anyone? :confused:
[HD2 Accessories] Willy318is:
This is some very very very Weird thing to know, I have to charge my device TOPS after 30 hours, with Almost no use at all, maybe 2 calls, 4 minutes each, plus 2 text per day, no Gps, No WiFi, no games, no videos, Nothing.

I doubt very much what you are saying to be frank.

Will
[HD2 Accessories] Eggy88:
My oppinion is that the Andidas are the better ones, they preform close to the stock ones. The Galilio are about the same, but having some problems in charging them in the device so often need to charge them in a charger.

Mine are somewhere in the middle. No way i can get my to last me for 4 days, 2 days at the most if i dont use it that much.

A normal day for me is 1.5 Hours of music + Web browsing (HSDPA)

10 SMS, 2-3 phone calls = total of 15-20min, and 30 min of playing with settings, etc.

after that i have 10-15% battery left.
[HD2 Accessories] efjay:
Eggy88, can you explain what issues you are having with charging the Galilio in the phone? I bought one but will send it back if it cant charge in the phone as I dont have a charger.
[HD2 Accessories] Eggy88:
I think that it is a issue with the internal temp sensor on the phone. It looks like it does not connect propperly with the battery and therefore giving wrong readings, as a result of this wrong temp readings the charging stops.

I have tested the temp of the batteries with a IR temp gun and they seem to be OK, so it must be the temp sensor.

This happens with 2 out of my 3 Galilio batteries, but not allways, maybe 50% of the time.
[HD2 Accessories] efjay:
Thanks for the info. I think I am going to chuck the battery when it comes since it wont perform much better than the stock, and go for the Mugen battery since that seems to be giving a tangible improvement in battery life and has no charging issue. Thanks for taking the time to report your findings.
[HD2 Accessories] efjay:
I got my Galilio battery late last week and so far it seems on par with the stock battery fresh OOB. Charging has been no problem with the phone on or off with no increased heat at all, charges OK when connected to a PC via USB cable as well. Today from 7am till now 2pm battery is at 82% with some browsing, email checking and messing about with the phone. Which is actually the problem I have with accurately measuring battery efficiency, I cant stop playing with the bloody thing!! :) However I will see how it performs over the next few weeks, the stock seemed to get noticably better, maybe the same will happen with this one.
[HD2 Accessories] PhilGood06:
I came across this topic while searching for something else...

Well , I bought on eBay two of these Andida batteries that are said to be 1600 mAh

http://cgi.ebay.fr/ws/eBayISAPI.dll?ViewItem&item=230471696197

To make things clear about enhanced capacity, I ran a simple test to compare them with the stock battery and posted results here:

http://htc-touch-hd.forumactif.biz/hd2-leo-f58/hd2batterie-2x-plus-puissante-chevalet-t15420-105.htm

Test is: Battery loaded at 100%, background lightening set to 60% manual, I put on the TV on and let it run till phone shuts down.

I also had a simple script running, writing elapsed time in a file every minute

Here are the results:

Andida *1600 mAh* battery: 185 minutes

HTC 1230 mAh stock battery: 190 minutes

After three weeks of intensive use (I'm using 2 batteries/day) I had no problem, they just perform as the HTC stock battery.

(I am charging them in a craddle with an extra slot for an additional battery, I haven't tried to charge them in the phone)

According to the packaging this battery *seems* to be of quite good quality:

So it is still a good deal for cheap replacement batteries.

But as there is a lie about capacity, everything else printed on this battery can be lie and my concern is whether this battery includes the needed electronic safety circuitry to prevent battery blowing in case of charger failure and over voltage

There is a simple way to check this:

I am considering to check it by plugging one of these Andida batteries directly to my car battery and also short-circuit the battery (using a long wire and being careful)

I think it's worth spending 10$ to make sure my HD2 is really safe with these batteries.

I'm just looking for the right place to do this, and I'll post result here once done.
[HD2 Accessories] Tubgirl:
I clicked on your link and it says... "1600mah Battery for T-Mobile HTC Touch HD2 T8585 Dopod".

Does that mean it only works on the T-Mobile version of the HD2 or does it work on the European version as well?

Brgds... /Tubgirl
[HD2 Accessories] PhilGood06:
That's right, I didn't noticed that.. what about this one ?

[HD2 Accessories] donalgodon:
Yes, the two models use exactly the same battery.
[HD2 Accessories] Moustafa217:
try to check the battery with a mulitmeter.. that should be suffiecient enough to know the exact mAh of the original and the extended.. :)
[HD2 Accessories] woaloo:
Multimeter do not check mAh because it's a power consuption, you need a resistance... It will give you voltage.

But you can use battclock on your phone for all these mesurements!!!

HD2 extended battery

Every one is talking from 1250 standard mAh battery that comes with the phone up to I think 1600 mAh?

And over in the UK, someone has a 2300 mAh which has a kickstand (as if you can't lean it up against something or just hold it. That is if you want to pay $50USD + for the battery+cover+ kickstand ...

Now I just ordered a 2400 mAh from Hong Kong, with cover without the kickstand. Cost plus air mail registration, less than $22USD .. now I'm figuring maybe 10 days to reach me. But when this gets to me and gives me additional hours for my new HD2 ... without kickstand will be well worth it.

In fact, I might just order a second battery as a back up. All less than the rest of you can order one extended battery from the UK with kickstand.

So really, is a kickstand (2300 mAh) worth $50USD+ from the UK? When it is possible to purchase two 2400 mAh batteries with cover without kickstand for about $45USD?

I'll give url when I see if people like to have the extended battery life without the kickstand.
[HD2 Accessories] Paten:
How much are you making off the sale of each battery? o_O
[HD2 Accessories] errorius:
did you know that the back cover of those cheap Chinese batteries do not fit properly?
[HD2 Accessories] Moustafa217:
yea man.. hes right.. there are of people who bought those cheap batteries and they dont even last as they are supposed to.. well maybe only in first few weeks.. then they would deteriorate faster than the original.. and the backcover will generally close from one side but not the other.. anyway.. let us know about urs when u get it :) goodluck with it :)
[HD2 Accessories] richard_b95:
Agreed, I was seriously considering buying a generic extended battery until I seen a picture of one attached to a HD2. It made it look god awful. The guy had to file the groove for the volume key because it wasnt big enough...:eek:

My dad has the official HD2 extended battery and it is FAR better.

There is a reason why sellers dont show pics of the thing attached.
[HD2 Accessories] nir36:
wait! :) what's the "official" extended battery and where can you get it? I want a 1500 one pronto

So far it didnt blew in mine. Had it till now. Even better than the original in terms of batt life. Well for me anyway. :)
[HD2 Accessories] lude219:
I'm still holding out for a true 1500mah standard battery. With all these people purchasing fake ones, you'd think either HTC, Mugen or Momax would muster up the courage to create one and reap the benefits. Oh well.

I dont even care if i have to pay $50 for it. You hear that HTC, Mugen or Momax??
[HD2 Accessories] ilordvader:
Ill buy one too :)
[HD2 Accessories] fi3ry_icy:
lol.. if its only u who is willing to pay $50, i doubt any1 would attempt to create such a battery.. we need more people voicing out that they want it too!!! me for example!!!!!!!!!!!!!!!!!! ;)
[HD2 Accessories] lude219:
Oh believe me, if there people desperate enough to spend $60-70 for the extended battery that makes their phone look like some GODAWFUL HUNCHBACK afterschool experiment, they'd probably willing to spend more than $50 for a standard size extended battery as well. And believe me, if i spend $900 on a phone, i could care less for another $50 or so for a better piece of mind. I just dont understand why we have the 1230, 1300....2600mah...BUT NO 1500?! I don't care if they're selling you a smaller battery just so that they could milk the extended one, I JUST WANT THE OPTION TO PURCHASE ONE.
[HD2 Accessories] mskip:
I dont really think HTC are that interested in producing an extended battery that would fit the same footprint as the standard battery. There just isnt enough profit compared to the income from their phones.

I would think the easiest thing for you to do (since there is never going to be a TRUE 1500mAh battery) is to buy 2 or 3 genuine replacement batterys with an external charger and just change them as neccessary. I always keep a spare one in my car, a spare one at home and a spare one at work so I am always covered if the phone starts to get low.

Trust me mate moaning about it is just a waste of time..

Be happy that you have such a great phone :)

Mark.
[HD2 Accessories] ilordvader:
What you say is True

but like we see in the Movies a flying car & now they have really made one :)

thats the hope we have too, one day our dreams will come true also lol

God Bless all
[HD2 Accessories] fi3ry_icy:
quite agree that a high capacity battery which fits into the frame of the small hd2 is not profitable for htc to design.. but if they could get 1 out, it would be good for their future releases as well :rolleyes:

jut to remain slightly on topic.. i found 2 other batteries (which are however not 1500mAh)

http://www.netimes.com/shop/japod-p...8585-htc-leo-1100mah-p-2598.html?cPath=80_731

http://www.netimes.com/shop/scud-co...tc-hd2-t8585-htc-leo-p-2553.html?cPath=80_731

the 1st is 1100 mah while the 2nd link is at a really LOW 950mah.. any of these brands ring a bell?
[HD2 Accessories] ilordvader:

so people can see if they really work :)

Im helping them in there sales lol
[HD2 Accessories] lude219:
I really don't understand how making PROFIT of any level is a bad thing (doesnt necessarily have to be HTC). When you create an extended battery that causes the phone to gain a few extra pounds around the waist, you're doing 1 of 2 things. 1) only a small percentage of people will buy it and 2) the majority of people who are on the cusp of making a decision, will likely pass. I'm sure we're in accordance here when I say that the reasons why the HD2 caught our eyes are the big screen and the slimness, so why would many of us risk that just to have more battery life? With thick candybar phones (~15mm), I could understand how producing really big extended batteries would make the most economical sense since the users themselves could give two hoots about the aesthetics, but for the HD2, you can't have the same train of thought.

I just don't see it.

You make a 2400mah and 10ppl buy it, while hundreds others are forced to buy fake ones.

Whereas you make 1500mah TRUE standard batteries and the hundreds who would've bought the fake ones, wouldn't mind purchasing it $50 or less.

Ironically enough, the fake ones are usually labeled as "1500mah" or "1600mah." So yea, I guess there's not a big market for those kind of size.;)
[HD2 Accessories] ilordvader:
They should also add a software

like in Laptops where we can see the cycle counts

of its battery Life

Like in Lenov laptops we can see

how many times the battery is used

& how many more times we can still use it

I think its 1000 counts

You might have had bad luck , but the one I got out performs my stock battery, and I have done the math using tbattery, while it may not be a true 1600mah, I can tell you this it is not a 1230mah ...
[HD2 Accessories] pathologo:
Found here.

If they were really able to make a 1600mAh battery for the HD2 with the original size, I really wonder why the respected manufacturer Mugen Power only manages to make a 1300mAh battery.

On the other hand people report here that the Andida battery is better than the stock one.

:confused:
[HD2 Accessories] reborn_hi:
http://cgi.ebay.com.sg/ws/eBayISAPI.dll?ViewItem&item=260639732611

you might want to try this the price is good. The battery lasted longer as i need to charge my original batt almost daily and i tried this and i can just charge it every 2 days.

its cheap why not ?

1600mah Andida Battery cost you 8.99

and

2 of these cost me less than 8 bucks .

& you suggest we buy from that seller
[HD2 Accessories] richo27:
Energy density.

Unless new battery technology currently exists with a higher energy density than lithium ion, you will only get a certain amount of energy from a certain amount of battery. So for those hoping that a 1600 mAh or more battery capacity in the stock size battery exists or will exist, its not going to happen until a higher (than lithium ion) energy dense type of battery technology is invented.

I believe the mugen battery is a tighter fit than the standard battery, so they have slightly increased the volume of the battery to get that little extra capacity.
