I have a U.S. T-mobile HTC HD2 and I'm currently travelling in Europe. I need to purchase an extra battery and I'm planning to purchase it from ebay but, I wanted to know if there is a difference in batteries for the UK HTC HD2 and U.S. HD2?
Is there a difference in the voltage or mAh? I'd rather purchase it from a europe seller so I don't have to wait on shipping if I get it from shipped from the U.S. although I don't want to purchase an incompatible battery and mess up the phone.
Thanks
No difference. The official HTC battery is 1230mah for tmous and international.
Thanks for the quick reply!
One more question, does the mAh make a difference if it's not 1230 mAh like official battery? Since I've found some that are 1100 and 1300. Is mAh an indicator to how long the battery will last? Since it seems the higher the mAh I've found the higher the price, unless I'm mistaken.
Yes and no. The mAh should make a difference (as in more=better) but 11 times out of 10 the 1300 mah batteries are a LIE. I got a cheap $5 battery from china that is supposedly 1350 mah. It lasts slightly less than my stock battery. For $5 I don't really care... In fact I'm quite happy having a cheap spare that actually works. The only battery that will definately give you extended life is the 2400(ish) batteries. They are huge and fat though.
Edit: I think mugen has a 1300mah standard size battery now for HD2 and they are fairly reputable so I would believe that one might last a bit longer.
BEWARE!
Beware, I bought an extended HTC HD2 battery from Europe and it it wigging out my internet connection and my MMS. Tmo has no clue why and neither does HTC.

Just was curious if anyone knew if the battery for the Rezound would be compatible with other HTC's like the Thunderbolt. Been searching but no real answers. I know battery life is gonna be horrible b/c i've been using the Incredible (original) for almost 2yrs and ended up getting a battery only charger swapping batteries. Thanks in advance!
I was wondering the same thing as I would like to bring over the Thunderbolt's Mugen 4500mAh battery. Although, it's one thing if the battery fits... but another all together if the antenna connectors on the rear panel will also match up.
Did some digging and found a couple of things. VZW sku ADR6425LVW. The OEM model number for the battery is BTR6425B which is compatible with the HTC HD7 and HTC Wildfire S. Couldn't find anything regarding the Thunderbolt although the battery model numbers were similar.

I can tell you for a fact that batteries from the bolt and rezound fit perfectly in each phone however one problem the voltage for a thunderbolt battery is 3.7 and a rezound battery is 3.8 so they don't match voltage wise.
I was also very curious about this. Was going to look for some cheap non-oem batteries like I did for the og incredible - i bought 2 1400mah batteries and wall charger for $13. they lasted about 75% as long as the stock battery did-

Same thing I did. Got a spare and an old Eris battery with 2 charge cradles.
This may be a long shot but since the Rezound is based on the Sensation...I wonder if we could order OEM HTC Sensation XE batteries? The XE did receive a bump up to 1730mah but the difficult thing is they are only sold in Europe.
It would be a nice OEM upgrade if we could get our hands on them.
HERE is a link for example
Actually the rezound battery isnt 3.8, mine says 3.7 on the back.

This is incorrect. The voltage of most, if not all, mobile phones is 3.7v. The Rezound is no exception.
The Thunderbolt battery will work, but there are different part numbers. I suspect that this is due to the Thunderbolt battery being slightly longer. When I put it in vs the Rezound extended it fit far more snug. Doubt it would matter, but there is a difference.
I am using both batteries daily. I start my day with my Rezound battery and when it dies I put in my TB battery. Its only a 1400 mAH, but it'll get me through those times when I'm not near a charger. One thing the TB batter does when in the Rezound is it grays out the battery icon on the notification bar with an exclamation mark over it. Despite the warning, lower voltage or whatever, it has worked fine and I have not noticed any performance issues.

Weird mine says 3.8, Id rather not have an error I think it would bug me even if there were no other drawbacks. I wont use a big extended battery. I need a spare battery and a battery charger soon I just dont know if I should wait or grab some thunderbolt battery's, I guess when charging my phone 3 times a day becomes more annoying than an error icon I will do it.
Available from Amazon: 1900mah http://www.amazon.com/Anker-1900mAh..._1_9?s=wireless&ie=UTF8&qid=1322269654&sr=1-9

Hmm, I would try it, I've got Amazon Prime, so returns and shipping are free.
Anyone else think it would fit based on the pics?
If those pix are accurate, I'm going to guess it won't fit because that battery looks more square as opposed to the Rezounds more rectangular shape. But if you have free returns, what the heck.
I searched far and wide for batteries from other devices that could be compatable. Only other I know of is from the Tbolt. The Sensation (including XL & XE) definitely will not work as the dimensions are completely different. The Evo3d is kinda close though.
I emailed that company and they would not be developing a slim extended battery for the Rezound.

You know what battery looks like it would fit. Would be a original EVO 4G. I still have my EVO 3D right here but that battery is more square. But the EVO 4G battery looks like a good fit. Not sure what the voltage is. I may be late Tp the game with this LOL....but better late than never

That would be great if you can do that for everyone. Companies will say they won't be developing for lots of reasons but number one is no access to the particular phone for testing. This just might be their r&d down for them.

Just FYI guys...
All lithium ion batteries in use for cell phones are 3.7v nominal. (voltage under moderate load, which is about half of rated capacity of a given battery... this is where we got the 3.7v rating standard) When fully charged the battery will be at 4.2v with no load. No phone actually puts enough load on the battery for it to read 3.7v until the charge is depleted enough. In fact these batteries are safe to discharge own to 3v (the real 0% empty for lithium batteries) but the minimum operating voltage for these phones is around 3.5v (which is about the 15-20% mark of the standard discharge curve for lithium ion) So the whole "never completely discharge your phone battery because it is bad for it" is bunk. You can't completely discharge the battery and 15% is a safe discharge level for the battery.
Also the mAh rating for a lithium ion battery is usually calculated from the empty 3v mark to the full 4.2v... So unless the phone batteries are calculated from the 3.5v mark then we can't use the full amount, but bigger is always better regardless. This fact is why I am wary about the off brand batteries that claim to have 100-200 more mAh than a stock battery. Because if the stock batteries are rated by usable power (4.2v-3.5v) and the off brands rated from the unusable 3v then the 100-200mAh difference is misleading as its not really usable. That difference is easily in the 15-20% range that would be left over in a battery only discharged to 3.5v
No need a different back cover...fits fine. ...titan is 1600mah. Amaze 1730 ..not that much of a difference but some help
Mind posting pics? or where you got it from.
can you also tell us how much it increases your battery life?
How about this one? 1950mah, no change of cover needed.

www.batteryboss.org tested some Mugen batteries and they didn't do too well...
I bought an Amaze battery and will post back once I receive it. I am not sure how I can most accurately measure the relative performance. Any suggestions?
Just bought one (labelled for the HTC EVO 3D, but still the same battery as the Amaze). I'm not expecting a huge improvement, as I am already getting awesome battery life with the stock Titan battery, but it never hurts to have a little more.
Looking at the Seidio 1900 one too, but not sure if I'd get it since its 3rd party...
Update: Battery just arrived. It was completely dead upon first boot, so giving it a full charge before I test it out.
any update on these batteries? any problems with the phone not recognizing the charge percentage?
any noticable increase?

Using the HTC EVO 3D battery, I think I am getting about an hour more out of it, which is to be expected since its not such a huge increase in mAh.
Otherwise, I'm not having any issues with the battery in the Titan. Phone is charging fine, reading the percentages properly, no issues at all.
I said I would check back...
I got the Amaze OEM battery and it works perfect. Seems to last a little longer, but it is not material. There is no very accurate way to measure that I know of.
Someone is selling the today for $3.99.
EBAY
Why do I not see this thread in the forum?
Never mind....
i'm hoping to get one of them as well . hoping to further improve on the battery life ! .
would just like to ask how significant is the difference ?
No material difference.
I bought HTC BG86100 BATTERY FOR HTC SENSATION XE XL 4G EVO 3D G17 1730mAh
I´m having some issues with the battery questionmark. Howto get rid of it?! Also when i charge the phone the led is blinking red and green.
Do you have use this battery? Does the titan?
I'm using this battery too (from the EVO 3D). Works fine, although the Titan battery does not fit in the EVO 3D strangely.
No problems reported and the battery does last longer. I would say 1 hour too.. Takes longer to charge as well, but I guess that is obvious!
deleted
I brought one of the Evo 3D / Amaze 4G batteries from HTC on Amazon (1750mAh vs 1600mAh in the Titan). The only thing I have noticed is that the Titans original battery is 3.8vdc and the Evo battery is 3.7vdc.
Battery fits ok and everything works fine when I boot it up. I have heard that the sensation XL only charges to 90% with this battery so I will report back after a full charge.
Anyone else had different voltages on their batteries?
From what I understand, the Sensations XE, XL, 4G, AMAZE, EVO 3D all use the same battery.
http://www.ebay.com/itm/250947417023
If this comes close to 2300 mAh, it is too good to be true.
Can anyone offer a good way to test that is scientific as opposed to just plain observation?
look forward to your tests!
why not test by recording your daily usage, on the same phone with same setup. Test should include what u were doing and duration.
Compare the original battery vs this beast for a few days to get a good feel of improvement/non-improvement.
Here is a quote from the seller on ebay:
"Thanks for your interest. The dimension of this battery is the same with the original one, so it doesn't need an external back door. But if your phone is customized version, it doesn't work with your cellphone.
But I need to be honest, this battery is offered by the supplier, and we don?t have professional equipment to exam its precise mAh. In fact, this battery is a little less than 2300 mAh. Hope you can understand. Actually, nearly all the batteries don't have the mAh as they are marked. Hope you can understand."
I wouldn't try it.
I have bought a replacement 1700mAh battery for the EVO 3D from a reputable brand, and the Titan cannot detect the remaining charge and will only charge it when the screen is on.
After reading some discussions on Titan batteries from a Taiwan forum: (in Traditional Chinese)
http://www.mobile01.com/topicdetail.php?f=224&t=2429110&m=f&p=1&img=0
Some guy bought an 2050mAh EVO 3D battery and encountered the same problem as mine. He took the battery to customer service, they updated some firmware on the battery to fix the problem.
The manufacturer then proceeded to release a new version of the battery made specifically for Sensation XL / Titan.
http://www.nexson.com.tw/ProductDetailShow.jsp?ProductNo=27
So it seems only the Sensation XL share the same battery as Titan.

Is your EVO 3D battery an HTC original battery? If yes, there are reports that it works fine in the Titan, but with 3rd party batteries you can't be really sure.
http://forum.xda-developers.com/showthread.php?t=1388441
I still don't think the 2300mAh battery you posted is worth trying, since it's probably overrated.
The HTC original EVO 3D 1730mAh battery is about 51x51x5.6mm in size. Minus the label, plastics and circuit board, the lithium ion battery cell inside is guesstimated to be 51x48x5.4mm in size, which is 13.2192cm³. Put the difference in voltage aside and assume the battery is 3.6V, instead of 3.7V or 3.8V.
According to Wikipedia, the volumetric energy density of an lithium ion battery is 900 to 1900J/cm³.
http://en.wikipedia.org/wiki/Li-ion_battery#Specifications_and_design
Taking the maximum, to be very optimistic, the battery would be able to store:
1900 x 13.2192 = 25116.48 J
The energy stored in the battery = (charge stored) x (voltage at which it is stored)
so
The storable charge = (Energy stored in battery) / (voltage at which it is stored)
giving:
(25116.48 joules) / (3.6 volts) = 6976.8 coulombs
1 Amp-hour equals 1 (coulomb per second)-hour, which is equivalent to 3600 Coulombs.
So 1 milliAmp-hour equals 3.6 Coulombs.
So the storable charge in the proposed battery would be:
6976.8 / 3.6 = 1938 mAh
So, being incredibly optimistic, the highest capacity you could get in a battery of the same size is could get is 1938 mAh or so. Even if the battery cell is 6mm thick, the result if 2153 mAh. No way that battery can be 2300 mAh.

Thanks! Finally some science. I already clicked the buy button. I do have the OEM EVO 3D battery. It was not a major investment or something. I did come up with a way to test the effectiveness if not the mAh, so I will post back in 21 days when I receive it.
So I Promised I would let you know what happend. I got the "2300 mAh" battery. I did get the question mark on the phone, but it worked intermittently enough that I could do a somewhat scientific test.
At full charge, my stock batters is 4400 mv
At full charge, the aftermarket batter was at 5212 mv (I know this should not be possible - clearly current was not being regulated correctly)
Don’t get excited!
Assuming that mv actually in any way were related to mAh; If you do the math, that represents approximately an 18.5 % increase bringing the battery to ~1900 mAh. Even though it is nowhere near the posted 2300, I would still be happy except…
After playing the same movie with no radios on for 25 minutes using fully charged batteries, the aftermarket battery had discharged 22% faster than the stock HTC battery. This means the battery will not even last as long as it’s smaller OEM brother. Apparently mAh as a sole measure is not enough. The efficiency that the battery is able to deliver power to the phone is just as important.
Bottom line - Not worth it…
Maybe we might have a 3500mah batt for the rezound!!!!
I have been a little disappointed with the rezound's extended battery and have had good experiences with siedio batteries on the Dinc.
I called siedio and they said that they wont be making an ext batt for the rezound. So in my searches for a battery i came across this
http://www.ebay.com/sch/i.html?_from=R40&_trksid=m570.l2736&_nkw=htc+rezound+batt
It seems that the same batt is used on the Rezound, thunderbolt and the mytouch 4g. I also come to find Seidio makes a 3500mAH batt for the t-bolt.
http://www.seidioonline.com/thunderbolt-innocell-3500-extended-battery-black-p/bacy35htmec-bk.htm
So the question i have is to any previous owners of the t-bolt or the mytouch:
Does the batt from these phones work in the rezound?
and
If yes - does the 3500mAH t-bolt seidio batt fit in the rezound with the rezound extended case. I currently have a call into Seidio's tech supp. hopefully they will give me an answer.
I sure wouldn't mind an extra 750mah on my rezound.
I just got a call back from Seidio tech support.
They told me that the batt works but doesn't register on the batt meter.
He said he actually had it in his hand and was testing it in a Rezound but he didnt have an extended back so i dont know if the verizon one will work.
He also measured the batt and said it is just under 1cm thick.
He said the phone powers up and seems to be working but he doesn't know what the long term performance would be like.
I guess there is electronics in the batt that communicates with the phone to track batt life.
Oh well don't know if i want to take a $70 chance with this.
It would be great if someone out there who has this battery could verify it.
I think I recall people having issues charging TBolt batteries as well. Not speaking from experience though but something to consider.
KORM via the beast known as the Rezound.
Another disappointing thing the Seidio tech told me - that there will be no 3500mah batt for the Rezound.

All batteries or just HTC t-bolt batteries? I mean does that include the Seidio 3500mah batt?
oh no... another one of these threads.
yes, a MyTouch 4G or Thunderbolt battery will work in a Rezound.
you will notice though that the "Wh"(wattage hours) do not match up(Rezound's being higher) so even though the Seidio one is 3500, it'll perform closer to a 3000 in the Rezound.
additionally, since the battery is not intended for the Rezound it has the potentional to do damage to the Rezound.
back in my Galaxy Nexus days, we found we could use Galaxy S II batteries in it. one of the GN users gave it a go for awhile and the SII battery ended up shorting out his device somehow & he had to get it replaced.

Oh yes another -
Problems with one phone/battery combo don't necessarily mean there will be the same problems on another.
Keyword - "potential".
It doesn't hurt to ask as someone out there may have tried it with success.
The Rezound or any phone does not have a WH rating. It has a continuous current rating. I don't know about the ratings of these phones but i would assume that the rezound is higher so, with voltage being ~ equal, the power dissipation would be greater.
The battery rating is not dictated by the phone. The battery WH rating is a function of the current/voltage and the dissipation time of the battery and independent of the device consuming it? So a 3500mah battery will deliver "X" mA's of power but for less time than in a mytouch due to the higher current draw (X) of the rezound.
In other words a 3500mah batt will perform like a 3500mah batt regardless of which phone it was intended to be used on.
Did you every buy a Thunderbolt extended battery and try in your rezound? If so does it fit with the Rezound Extended battery back?
guys i just traded my thunderbolt in for a rezound. like a damn idiot i shipped theTB's 3500 extended battery back to verizon but before i returned it, it lasted the same amount as on my TB. im gonna try and get verizon to ship it back to me because this rezound extended battery isnt as good.

Yes. I have the OEM Thunderbolt extended battery (made by HTC) in my Rezound right now. In fact, I've had it in since I bought the phone on ebay over 2 months ago. The previous owner had the OEM Rezound extended battery and back at one point, but lost the extended battery. So he substituted the battery with the extended battery for the HTC Thunderbolt. It has the exact same capacity and dimensions, but is black instead of red.

I tried my OEM thunderbolt battery in my rezound and it showed the battery indicator grayed out. Didn't show how much battery life I had/had left. And it didn't charge at all.
So I would wait until someone confirms that the seidio tbolt battery works in the rezound before buying.
Just buy the HTC extended battery for your Rezound. It lasts me 12-16 hrs of heavy use.

"heavy use" varies from person to person. for me the HTC extended battery lasts 3 - 4 hours "heavy use".
i'm probably just going to order that mugen 4000mah battery.
It's official, it does NOT work
Based on encouraging info here and in other forums, I decided to try this. I ordered the 3500mah battery for the Thunderbolt made by Seidio from Amazon. It came with the Thunderbolt extended battery back (which you do not need) and the battery, in a clear plastic snap-together case.
The battery does indeed FIT inside the Rezound using the extended battery back that I already had from buying the Rezound extended battery from Verizon. The Rezound will power on and will work with this battery, BUT
1. The battery icon on the notification bar will display a strange symbol, where it does not seem to understand the current battery charge level. A workaround would be to load Circle Battery Widget (free from market) which did seem to report an accurate battery level.
2. The killer - you cannot charge the battery using your Rezound, or a Rezound external charger. I plugged in the Rezound to a micro USB charger that I normally use and it looks like it's going to charge for a couple seconds (solid amber LED) but then it starts blinking alternate green and amber on the LED. This means there is a battery issue. Left it plugged in for several hours and the battery did not increase its charge. Also tried removing the battery and using an external charger I had for extra Rezound batteries, and it would not charge in there.
I packed the battery back into its plastic case and returned it to Amazon. They accepted the return and refunded my money.
Disappointing... The stock Rezound battery is useless. Even with an extended battery I have to baby it, turn off 4G and keep WiFi and GPS off unless I need them. Occasionally bump charge it or try to keep it above 70% for several days at a time or else it starts discharging at an alarming rate (dead by noon). So I have chargers next to my bed, in the car, and at work. I miss my old Incredible - with the extended battery I got all day even with 5 hours of GPS during a round of golf and some Wifi at home or work. Boo!
What the hell is wrong with your phone? To be fair, today was a light day with only 3 and a half hours of screen on time so far. But still... No reason the extended can't last the day.

Keep in mind everyone's experience will be different. Most people forget that Android is constantly looking for the strongest signal. The one thing you can be sure of is that everyone's phone will discharge at a different rate for that reason alone.
Beyond that you have to consider cpu speed, app configuration, memory leak, phone configuration, and a whole myriad of other factors that can contribute to drain.
I had the extended battery for about a week. In the areas that I live/work, it performed only marginally better than the stock battery. This was most likely due to how I had my phone configured (mostly conservative towards the end). However, for myself, if I feel I have to run this beast of a phone on minimal settings, there's no real point in having it. I made the compromise to return the extended battery and just buy additional chargers. Indeed, I have one on my nightstand, in the car, and on my work desk. The only time I'm really without a charger around is on the weekends when I go out at night. The stock battery performs fine for those purposes.
I will continue to monitor these threads until a suitable extended battery seems to give the majority of us the performance we need.

For the record
I've used this particular HTC Thunderbolt battery in three different Rezounds, with no issue. It seems to perform equal to the Rezound Extended Battery (both 2750 or 2700).
The part numbers on the battery are THE SAME. So at least for the normal extended battery, they (if part numbers being the same means they are the same) have no compatability issues.

I've been using this in my Rezound for a few weeks now.
So ANYONE getting an Extended Battery for their Rezound, and need a little more juice, GET THIS BATTERY! It's $4! It's a perfectly good 2750 extended battery (completely legit) from HTC (not some garbage third party). They're dumping them as a result of overproduction I assume.
It's worth charging one of these up, and keeping it in your glove compartment for a rainy day (that's where mine is).
Everyone. Should. Get. This. For the price, I don't know how you couldn't. It's just that the HTC logo is upside down from the Rezound's (which doesn't matter).
So as an Extra extended battery, it's 10/10.

I got the OEM Rezound extended battery yesterday. Full charge, lasted a decent amount of time. But nothing great.
But I was on 3g, and did stream about 20mins of video. And I surfed quite a bit. But my evo 3d with the 4000mah battery kills the rezound.
I will have a better feel for the battery now that I am back home and on wifi, then on 4g at work. Thats more of my real life usage.
