HTC Extended Battery 1340 mAh BP E270: Nice or Ugly?

I'm interested to buy this, what do you guys think? For those who have this, any feedback, including its performance, would be appreciated. For the price, I can actually get two HTC or four Momax 900 mAh batteries, so I'm not sure if it's worth it. By the way, the cover is mat instead of glossy.
I found the pictures on Google.

Well, I really love the matt finishing and overall high quality. Thats the finishing that HTC should have given in the original batt.
With the old glossy surface, the pyramid peaks are very vulnerable to scratches, and you can see whitish tiny scratches on the peaks. With the ext-batt's rubbery surface, it's almost scratch proof. I've been using the batt for 4-5months and it's still perfect.
As for the thickness.. frankly, 14mm is still thinner than most PPCs out there.
Enough of aesthetics.. My phone now lasts >50% longer.. which is good for me. Thats abt 2 days with some MP3s. Used to be low end of every day, which makes no sense coz you know 15-20% batt won't get you through the whole of next day.
My advice is.. get the batt as a long term investment. If you're gonna sell the phone after 6mths, bear with the lousy original batt.

Hi MasK, thanks for the input, it's very helpful.
I think I will probably keep this phone till November or December, because by that time I can get a free phone from my provider, I will just sell that right away and the Diamond to get something new. Yeah the glossy finish is really easy to scratch, right now I've to use a case to protect it.
There is another option that I'm considering, it's the HTC battery bank BB G300. It's sightly more expensive, but I can keep it for future HTC phones or any phones that use the same connector. The only thing is I'm not a huge fan of carrying extra devices on me.

Extended battery
I decided to buy this battery when I one day ran out of battery at 7pm and desperately needed to send an email.
It certainly improved battery life by up to 50% and i don't think it makes the phone uglier. It's only a few mm thicker (i think 3mm) but only the fact that I get two days out of it with hotmail pushed and OWA pushed through emoze and average calling, texting emailing and surfing, should convince you to buy the battery.
The only problem I had was the HTC pouch that came with the phone. When you have the extended battery on, it won't fit your diamond any more, so I had to buy another one (a generic HTC leather pouch).
Hope it helps...

What I don't understand is, why do they only thicken the battery? They could also use the new space above and below the battery (looking straight onto the backside of the Diamond).

I think it's not as simple to produce a battery in some odd shape, they also have to consider about the compatibility with other models.

I got mine last week and it's great.
Mat finis is actually better than glossy - no fingerprints and I think it's going to be more durable in the long run.
As for battery life - now I can use my Diamond normally for two days, I had to charge the normal battery every day.

I just received mine today, I'm glad I went for it.

looks like im gonna have to invest in this battery...

I've decided to go for it, and have orderes the BP E270.
Can anyone recommend some cases that would fit the 3mm fattened diamond?
Thanks,
Dave

Having owned the extended battery (and getting rid of it). I have to say I didn't like at all, the phone just felt wrong. I appreciate it only make the phone a couple of mil thicker but trust me, it wrecks the feel of the phone. If the phone came with the exteneded battery to start of with, I may have been happy with it.
Another problem I had with it, was that the back was always coming loose and sliding forward when I tried to take the phone out of my pocket.
If you are having problems with the power of your phone, then by all means get the extended battery but I'm telling you the extended makes your phone feel like a brick and even worse, makes it feel cheap.

I tend to disagree, the phone feels much better in my hand (my opinion), I liked the thin looks of the phone with the original battery, but I could never hold it properly, it slipped from my hand a couple of times, lucky it fell on the carpet. Now I like it much better, plus having the added benefit of the extra power. At the end of the day, it's a question of choice, some of you might like it, some of you might not, I don't think there is a right or wrong answer here.

Mine has arrived, and I really like it. As said earlier, the matte finish is much better, and the small increase in size actually makes it easier/nicer to hold.
Any suggestions on a pouch or case that fits it?

The extended battery is actually the same thickness as the 900mAh battery with a silicon case ;-) Actually I normally use a Tek Sock pouch with my extended battery.. but for now, i just have a screen protector and will try for a few days without a pouch/case.

hi i got mine today its beetter than the old one htc must have done this before n replaced all batterys like nokia did for mathatushita battery which recently got blasted
i got it for RS-3,000 inr< indian national rupee> wat abt others cost

just got mine yesterday.. however mine is the white colour version.. so still have the glossy back cover..
i check the battery status using powerguard and the battery voltage is always around 3.9V to 4V.. and the phone gets heat up v fast.. to more than 39 degree.. is my battery faulty or it is normal for the extended battery to behave like this??

im playing games.. but when using the original 900mAh battery, it wont get so warm.. with the extended battery, when it have around 80% battery left, the voltage is like 4.1V to 4.2V.. which i think is very high.. thats why causing the phone to heat up so much..
can anyone confirm with me that it is normal to get 4.1V to 4.2V when the battery life is more than 70%?? or is my battery faulty?? it will drop to 3.6V to 3.7V when battery life is less than 50%..

I've got mine today... I thinks it looks better than the glossy one and with the extra mAh...
Does anyone found a good case for the new package?

Anyone can help me find an another one battery, seems that it's ran out of stock now !

need MDA compact IV(P3702 victor) battery advice

i'm currently looking at this battery:
(image links to ebay)
which seems like a nice cheap battery for extending my phone's battery life.
i'd like to know other people's experiences with this battery though before buying it.
some questions:
battery:
does this battery interfere with GPS like some extended batteries for the original diamond do?
does this battery really noticably increase battery life?
has anyone been able to check if this battery has any negatives with long term use?(phone damage, or large reduction in battery life after active use)
is battery charge properly displayed?
cover:
is it made of good material?
the camera opening: can you feel a hole or is there a smooth transparent cover at the same hight as the rest of the cover?
does it fit properly?
unfortunately all quality related info i could find was from webshops selling this battery, and from the manufacturer itself, which isn't really a reliable source.
EDIT: if you know a better/smaller battery, please tell me.

I got this battery just over a week ago. Figured it was so cheap it was low risk. I'll try and answer your questions.
GPS was affected. It still worked but took a long time to get a fix. I applied the silver foil fix in this thread and now it is just as good as with original battery. http://forum.xda-developers.com/showthread.php?p=4341412#post4341412
Battery life is massively increased. I had stopped using my phone coz it wouldn't last a day. Now I can use GPS for a couple of hours and do some browsing with power left at end of day. So far I have never run out but I still charge everyday because it has been quite low a few times.
Can't speak about long term use
Battery charge seems to be properly displayed.
The cover is not brilliant. It fits but it is a bit creaky. It's just about ok.
The camera opening is just a hole. There is no cover for the lens. It's unlikely to get scratched as it is a deep hole but dust does collect in it.
I feel it was a good investment and I am glad I bought it.

thanks for the info.
i think i'd rather go for a good standard-size battery though.
i really don't like the idea of having a hole for the camera.

PHOTON Q extended battery MOD

Ok heres the deal
This is not a HOW to but More of its, Possible and How i did it, My Mod is very raw, and ugly, but it is sturdy and Functional so I felt it was worth Posting
Materials Used
I had several things Lying around that aided this Mod Greatly First was a Dead droid razer Maxx someone gave me that did some time swimming when he fell off his boat
So I used the Eb40 3200 Miiliamp battery as the base for this Mod
I pillaged the Following from the razor Max board
the Power Connection
i used baking soda and super Glue to secure it into place into a hole I cut into the Photons Back cover after securing the new power connection I wired the new battery to the photon Q board, on this part I soldered the Data wires very gently using the Hard won skills I earned while doing the sim card mod on the same phone, this connections are done very lightly with very thin wiring, leaving it reverseable if i so chose todo so..
the EB41 battery and the eb40 battery have mirror image connections to each other so when wiring up the eb40, remember to arrange them in the correct order, which is Opposite the eb41
now i built a harness for the eb40 battery using a cheep 3 dollar rubber coated case off amazon using the same baking soda and super glue trick to build the pocket to hold the battery, then doing a wee bit of finishing using JB weld
Im not sure how to attach photos here but will give this a shot, enjoy and I wish you Luck if u wish to attempt this yourselves using what I have Pioneered

...it looks crazy
unfortunately this is not save for charging ic inside phone

how so? hopefully not something i missed the orginal eb 41 is gone are u speaking of a resistance issue with the new wiring? i guess im a bit confused how does any other phone accept an extended battery if not in this fashion?
the mod basically just provides an external jack on the back of the phone to accept the eb40 the unit has been charging fine
but if there is potential for damage please elaborate

also a reminder that bbig ugly thing is a modified protective case backing to hold the its not part of the phone

havent much to post about on the cosmetic end of things, but id like to report that still going strong with an average battery life of 2 days between charges or 4- 5 hours of straight ingress play if the mood requires, so id say the mod is an overall success inspite of its socks in sandles cosmetic apperance so i will choose the much extended functionality over the poor cosmetic appearance, but each day this phone sees very hard use as it bascially functions as my first line of use for all my work invoicing and parts researching I do 8 -12 hour days of appliance repair work, and a charge usually lasts an entire day now vs the dead in 3 hours the previous battery offered me, so after all this elapsed time, i can say to anyone else wishing to try this, mine has been a total success, and when i get around to making it pretty ill post pics

I applaud any mod. But in this case I am wonderig why you didn't order one of those USB powerbanks on Ebay for $ 10,- and replaced the 18650 internal battery with let's say a decent Panasonic 3600mAh? That's what I did. It can fully charge a Photon Q and is about the size of an oldskool bubble gum pack

Has anyone succesfully replaced the Nexus 6P battery?

I am looking to replace my battery on my Nexus 6P, I've abused it in the form of basically charging it all the time, all 8 hours at work, it sat on the charger all day, since I use it heavily. I now know the erro of my ways and I want to repalce the battery.
I've watched videos on how to do it, I know it's not easy, but it is possible. Has anyone here changed it, also where did you get the battery, I've found them anywhere form $10 to $50, I ahve no problem paying more if I know it's an OEM battery.
Thanks in advance.

Maybe someone, but I've not heard of anybody doing it....

Not here either....seems like a terrible time haha Best of luck to you if you try but when my battery life degrades to that point I will be parting with this phone and either buying another one of some sort. Even working with electronics for years there no way I'd personally succeed the first time lol

I have dissassembled my phone to replace random components after falling on it. its not that hard to get apart in my opinion, and its super simple to replace the battery if you can source the battery

Right! The teardown video I saw made it look not that bad, and I toar apart my Galaxy Nexus to replace the USB port on it back in the fday, and that was actually fun, granted it had a removable back with easier access to screws, but still.

I have been eyeing the oneplu3 and oogling over the supposed specs on the oneplus4, so I'll probably go there as soon as it's released, but my battery is bad, I get 2 hour SOT if I'm lucky, this phone used to give me 4+ easy.

If you have to open up.
Buy extra camera glass pieces. Thats literally the only thing that normally goes wrong if you dont have a real heat gun. Dont thing hair dryers will do the trick unless your extremely patient. I plan on replacing the housing soon.

You just made me sad, I hadn't really looke dinto the oneplus all that much and dind't realize VZW data didn't work. I'm on an unlimited VZW plan, crap.
Hopefully the oneplus 4 has the ZVW radios. Now I really need to change this battery.

Haha yeeeeaaah all that GSM crap and all their "nice" phones Good luck if ya try man, you're more adventurous than I!

I've successfully done an internal component swap. Swapped the motherboard and battery from a very beat up N6P into one that was in excellent condition but was basically a paperweight.
The most difficult thing about this project was not getting into the phone, but getting into the phone without leaving any noticeable scratches. Removing the camera glass and the plastic strip at the bottom took at least half an hour of heating and gentle prying. Getting the screen out without a suction cup tool was a bit tricky too, i had to wedge in a chisel x-acto blade and pry it up, lucky no damage was done.
My advice would be to have on hand as many of the tools suggested in the youtube videos and to be patient while do it.

Good to know
Thinking about doing mine

I've never taken mine apart but if I plan on replacing my battery I will buy the replacement glass piece and bottom plastic piece at the same time. Those are the only pieces that can get damaged in the process.

I just watched that video. from the looks of it, so long as you take your time. and have that suction cup tool, it should be fairly straight forward. at least you are not having to separate the screen itself from the guts to get inside.

Looks like my battery is on its way as well.
Anyone sourced genuine replacement yet?

Have you considered getting a battery case for it?

Why?

I understand the 2 out of 10 rating on iFixit after replacing the back cover on my phone. 90% of the pain is getting to the 6 screws. I don't think it is possible without scratching up the old cover. Funny thing is that I just wanted to change it from silver to black. A heat gun is a definite requirement. Not for the faint at heart for sure.

Upgrading the S10e's battery theory?!

I had an idea.
I previously owned an S10e that was second hand and the phone's battery was so bad it couldn't last through the day.
S10e battery ( EB-BG970ABU )
I was craving for a big battery so I ordered a Samsung M51 with a large 7000mAh battery but I still cant get over the feeling of a small phone in my hands. I loved my old A5 2017 and s10e is almost the same size.
So I was thinking maybe I can upgrade the battery. Both S10 and S10+ have a bigger battery as in capacity and dimensions. But then I looked for an earlier phone. S9?
S9+ battery ( EB-BG965ABU )
It has the same connector but I don't know the dimensions so I was hoping any1 can help me with this case.
Thx to all. <3

The S10e stock battery measures 42mm wide, and 71mm tall; not counting the circuit piece, which adds another 5mm to height. My battery is still glued in, so I can't measure its thickness (yet). I too have been thinking about changing my battery (downsizing), but the apparently attached circuitry is puzzling:

Thx soo much for this information. Im searching far and wide and the closest thing is the s9+ battery as mentioned. I will try to find some infortation and wll go on from there as im probably not the only one trying to get the most out of a great phone.

Ohhhh ok then.
I asked store owners on aliexpress selling batteries and they were kind enough to send me this. It's sooo close.

So it appears alternative batteries come with their own attached circuitry on top. Might work for you @YoungPumpkin but probably not for my wish to downsize. Your wish for more mAHr capacity will hinge on making larger battery fit. Phones of the past did this via thicker battery and special back cover with a little buldge.

I could desolder the cercuit of the pther battery and solder it to the new one as thats how they are connected right? If i wanted to fit the bigger battery in the s10e i would have to modify the phones metal body and thats not a problem. But idk if it would work software side of things. And what do you mean by downsizing? Why do you need a smaller battery?

I prefer a light weight phone; had S4 Mini for years. It was under 4 oz. Was forced to upgrade due to poor voice connections due to carriers changing to VoLTE. S10e was the least of the heavy weight evils for me. I have chargers everywhere, on my desk, next to bed, near easy chair, in my car, etc. The lowest my S10e battery has ever been is 82%. I'd like to take an ounce off its weight.

Ohhh. Then battery is ur only way of waight reduction or maybe if u find a custom plastic back. Thx for your help anyway.

The s7 edge had a 3600 mAH battery , 100 plus than the s9 , and if ur into desoldering, you surely could do it , and if you do, post a guide as well .

I think soldering the chipset of the battery isn't the problem. It has to fit or at least almost fit without destroying the chassis too much. I"ll check the dimensions of the batteries and compare them.

Back in the day they used to swap the s7e's battery onto S6 flats , so surely you will find the proper dimensions for it , also the phone is a tad smaller than the s9 , close to the s10e's dimensions so by that logic, the battery should fit better ?

here's something to give you an ideea about soldering the connector thingie on the other battery Battery connector swap

the soldering part is the easy part. I'm worried the battery won't fit because of the size. s10e's battery is roughly
I just noticed there is a code on the battery that determines its size 1/CP6/44/77 [s10e] and that's where it bottles up.

damn, s10e's battery is THAT small? pff, what's the size of the s9+'s then ?

i think the s9+ is pretty close

Maybe if you flip that top connector , in case it is flexible , then there shouldnt be a size difference issue .
Also dont they make the cutouts for the batteries bigger now, to allow them to expand (since the note 7 issue ) ?
Let us know of your progress, I have an s10e as well & it's brand new for now, but if you manage to get a bigger battery in it, i will open the back glass too .

I was planning to upgrade the battery when I bought the s10e the second time but I wasn't sure so I opened the form to talk out the possibilities. as of right now my battery isn't that bad but when it does get bad I might upgrade because I like the form factor of the phone.

Hey there,
I've been searching around for a topic like this since forever now, only thing i could find is a YouTube video which wasn't clear enough.
Since my battery health was already dying on s10e i thought about an upgrade instead of replacement but couldn't find similar dimensions to s10e's battery.
Then i got a juice pack but it made the phone bulkier and the continuous charge would heat up the phone + increment on the charge cycles of the battery.
Already tried s9+ battery but it doesn't fit in the frame horizontally
Though vertically it was a perfect fit and a bit thicker overall
I replaced the complete pcb, removed the battery's covering and adhesive strips , didn't make much of a difference either.
I've contacted a lithium ion battery manufacturing unit located in china
Who make custom batteries with your preferred dimensions but in Bulk and they were ready to ship 20 pieces for 7$ each .
But i highly doubt their performance or long term usage when compared to the Samsung manufactured ones .
Also you'd have to desolder the current pcb from your phones battery or else source PCBs from china in bulk again .

How much battery does it stick out horizontally? And what would be the custom battery capacity? I think the only option is a s9+ battery to my beliefs.
