2000mAh battery for S710 ?!?

i`ll love to have a bigger battery for my S710 and searching with google i found this link and I must say it`s quite appealing ... but it`s for real ?!?
what do you guys think about it ?
later edit:
i have found another link to a 2000mAh battery

Would be nice, but did you see that you have to use a new battery cover which stands out quite a bit! It just looks ugly!

you are right about the look, but 2000mAh vs 1050mAh will be nice to have so you don`t want to charge it every day just be to sure you are not going empty, right ?

Hello. Just bought one (with the cover) very cheaper from ebay (15$ with postage) and I'm very surprising about it. It's big and heavier but it's a good deal to have one if you want to keep your phone on for many days ... I could surf on Wifi, make calls, navigate on Tomtom, hours and hours, days and days, and I don't care anymore for the power. It's a 2200 mAh and it fits very confortably in my jean's pocket. It is not ugly as we think as the phone is already not an ultra design and slim item as the iPhone, an LG or a samsung. So nobody care about it ... ;-)

i think i`ll buy one

I also bought one thru dmc batteries for 6,95 british pounds.
Very curious how it will be

Extended Battery

Well, I've gone ahead and pulled the trigger on an extended battery and back cover for my S710 since I got it used and the battery is half way after a full day usage and I need more since I'm not always near a charger for a few days - though I am happy it can charge via miniUSB since most people have one for their digital cameras.
So I shall update once I receive it and we shall see truly how uncomfortable it will be with the larger battery door. And it was only $25 shipped on eBay. 2250mAh of goodness will soon be arriving.

you mind putting up some pictures of how it looks with the extended battery? side views, and comparisons with the orgiinal side by side shots if possible.
oh and what kind use do you use it for, do you have bluetooth on, wifi on? or both off? etc.

http://www.gpsforless.co.uk/product_images/9889_4.jpg
more info here

I have mine already a couple of days. By mistake they send me the wrong lid , I got the one from the S630. Wow, what a biiiig device that is. I'm happy having a Vox
So, they immediately send me another cover, waiting for it now to arrive....

Woah, looks big with the extended battery and cover on it, lol. Hopefully it's still useable. birdibird, when you get your cover - post up some pics, also if you could tell us where you got it, how much and if your new cover still has the rubbery HTC feel to it (when it arrives).
I'll post up some pics of mine when it comes in!

I was wondering how many days of use do you have with those 2250-2300MAh batteries??
I read that someone bought them from megacapacity, others from eBay, others from gpsforless, and others from BoxWave
Can we make list from what of those batteries bought from where, went good and waht went bad?? also advising the other from wich ebayers we should not buy?
Is it allowed by the forum's rules?
Think it would be usufull to everyone

I bought one from eBay and one from BoxWave. They are both the exact same thing. I also still have mine for sale, used for roughly one week. The only subtle issue with them both - is that the contact pads are recessed too much. I had to pad them with copper in order for the pins on the Vox to reach properly. You can also pull the pins out of the Vox a few mm which will assist.

Thanks H4waii
for your cooperation!

ANy other experiences?? Fro what I remeber you where quite a few who bought an extended battery...

Hello! I use extended battery for about a year. What to say... It gives me a chance not to think bout battery at last one day using Vox (calls, GPRS, music, reading and also playing games).
To say, I'm going to buy one more extended battery, because ... I like my Vox but such battery can disappear from the market...

MDA Compact IV official extended battery+backcover

Hi Everyone,
Any one got this already:
http://www.easydevices.co.uk/pp/T-M...OMPACT_IV_OFFICIAL_EXTENDED_LIFE_BATTERY.html
It says: In Stock
Can anyone please share some views about performance (GPS,camera, etc.)?
And, what is the most important, does it significantly improve everyday device life?
Thanks.

ooo nice, though that is alot of money for only 1/3rd increase in power,

hi,
yeah, I personally think the price is horrendous.
that is why I want to check whether it`s worth that price.
For £50 you can get 10x 900mAh batteries plus charger ;-))

actually a 50% increase in battery life. i have the Dianond version - well worth the money in my opinion.

Is there anybody who knows when to buy in Germany?

Ok,
I was waiting long enough now, hoping I will get cheaper one from eBay.
I`ve found only 1 seller offering 1800 mAh with ugly humpy cover, so I`ve decided to go for Expansys original one.
Ordered on 1st of Jan, paid £62 with delivery (bit expensive, but I`ll put it on as the Xmas present for myself ), expecting it tomorrow.
I`ll put some photos probably tomorrow evening and put few words about its performance later on (I need to test it first).
Happy New Year to all!

Expansys runs the business all around the world, I`m sure what they offer in the UK is available in Germany as well.
There you go mate: http://www.expansys.de/p.aspx?i=171125
It is 63.99 Euro + delivery.
Cheers.

If I have the T Mobile version (MDA) and I got the Diamond back cover... would it fit?

Hi,
No, I`m affraid it won`t fit. MDA Compact IV has rounded corners, while Diamond is strict rectangle.
There were a few threads about it already.

Hi,
Got this one from GPSforless
http://cgi.ebay.co.uk/ws/eBayISAPI....name=STRK:MEWNX:IT&viewitem=&salenotsupported
and it fits the MDA Compact and the GPS seems to work.
Will post once I have used it a bit.
Regards

Hi,
Did a Tom Tom test today. Basically Tom Tom running in demo mode, but with a GPS signal (varied from 3 to 6 sats), backlight on auto. GPRS was on and email was downloading every two hours, weather every hour. Got a total of 5.5 hours. Battery percentages for each hour shown below.
1.93%
2.64%
3.55%
4.44%
5.20%
I did a test with the standard battery before and it was about 2.5 hours.
My MDA Compact III used to get only 4.5 hours so with the extended battery the MDA Compact IV is actually better!!
The extra bulk may be an issue for some I suppose, though I will mainly use this battery for GPS use on my bike. The normal battery usually runs okay for me on day to day use of the phone.
Regards

OK, I`ve been using this extended battery for 10 days now.
With 10 texts, 20 minutes of calls a day and 3G switched off it lasts for 3 full days (72h), which I find is very good, compared to 30h on original battery.
The new cover looks very good. It has black/mate finish and has got an ornament (see photos).
My MDA Compact IV is about 3mm thicker and a bit heavier, but it hasn`t lost his sleek and flat look, which was the reason I bought MDA Compact not Daimond. Also, I`ve got a feeling that new size and weight makes it is laying better in my hand.
I had to go for another car holder. First, I though that my Compact with new battery (thicker) will fit into cradle for Touch Pro, but NOT, it was too loose.
So, I`ve bought universal one that will fit from small Nokia to big PDA (can give link to ebay seller, if anyone is interested).
I think the new battery+cover is worth its money.
Cheers.

more photos
here are more photos chaps.
I forgot to add:
It is ORIGINAL HTC extended 1340mAh battery with new back cover, especially for T-Mobile MDA Compact IV.
Very good quality, not cheap HK stuff. And NO AWFUL HUMP!
GPS works OK, absolutely no change compared to the original 900mAh.
No other issues noticed.
I`ll keep you updated when I notice anything.

Very helpful, thanks Tom - I think I might go for this. From where did you purchase the battery/cover? Also, do you have the original HTC pouch - does it still fit inside?
Thanks

Hi,
There are two on-line shops offering these extended capacity batteries:
Easydevices - http://www.easydevices.co.uk/pp/T-M...OMPACT_IV_OFFICIAL_EXTENDED_LIFE_BATTERY.html
Expansys - http://www.expansys.com/p.aspx?i=171125
I went for one with Expansys, it is a bit dearer than Easydevices one, but I found Expansys more trustworthy and besides if you look at "Easydevices Terms & Conditions", you will notice that if you (for some reason) have changed your mind and want to send it back, they will deduct 20% as a "administration charge", so they will refund price minus 20%, which you can calculate yourself easily.
I didn`t know what I`m gonna get buying over the net, in terms of quality and peformance, cos I couldn`t find any opinions, nor feedback.
So in case, I didn`t like it I went for Expansys one, they don`t do such a "small print tricks".
It will fit original pouch, but for me it`s a bit too tight, especially when someone is calling you and you strugling to take it out to answer.
I`m using "temporary" pouch at the moment - it is SonyEricsson`s and still looking for a nice sleek leather one that will fit my new fatty toy.

That looks sleeker than my "hump" back. Although I personally wanted the double capcity so it does not bother me so much.

Yeah, but there is no photo and it doesn`t even say what kind of backcover is included - with ugly hump or flat?
Is there any one, who went for it, to share some info?

I received mine for my mda C.IV last monday and after a week of use, it was worth every penny. It took a day or 2 to get use to the 3mm addition but i now get 2-3 days use out of my phone between charges were before i barley got 1. Highly advise everyone with battery issues to get one!!!

[BATT] [27-03-2009] 1800 mAh MDA Compact IV with pictures - not official one

All,
I managed to source a non-T-Mobile extended battery and cover for my Compact IV. I believe the original costs in the region of £40-£60 (for a 1340 mAh).
I've just purchased at 1800 mAh one for about £12 GBP ($18 USD).
Up until now, I personally was finding it difficult to find a 'replica' extended battery for the Compact IV (different cover to the HTC Diamond of course).
Anyway I thought I'd post some pictures up if people wanted to see.
I won't post a link to where I got it because I haven't tested the performance of it (just received it 30 mins ago!).
My usage is pretty heavy where the original 900 mAh would barely last me 8 hours on a good day.
I will post back results later if anyone is interested.
[UPDATE 27-03-2009]
Well I've been using the battery for a few days and of course it is as expected far better than the original. I haven't tested it with any perfomance software tools, just real life usage.
Full charged at 8am, the battery would easily last me 48 hours. Over this period I had a data connection always on (Exchange and personal IMAP). Just for testing purposes, I had the GPS (Tomtom) running for an hour, browsed the internet for a total of about an hour, plus the general calls and SMSs made/received.
Just one little thing: I had to remove the sticker around the battery because the cover simply would not close, I instead used sticky labels to cover it and now it fits like a glove! I personally think the whole unit feels better in the palm of hand with the extra thickness.
Overall, so far, I am impressed with this battery.

cool, i'm interested to hear your feedback once you use it for a while. thanks for posting the pictures.

Sh500,
Please give us a link to where you bought the battery, I'm really need one!

I'm a bit concern about removing this sticker around the battery, would this effect the battery in anyway? Did the seller not test to see if the cover closes with this battery?

This is the best cover design which i have seen

I also bought this same battery from the same supplier on e**y, and first day use already a vast improvement on the pathetic original. Fully charged from new this morning, 1 hour mp3 listening, plenty of emails, web-surfing, phone calls, etc and battery power has dropped by 3 bars, normally its virtually dead by now with the standard battery. I would consider myself a heavy user. The battery cover feels a bit plasticy (but seems strong enough) and as was said in the opening post you do need to peel the stickers off the battery to make the cover fit the phone (voiding any warranty for the battery) but for the price I think this is a winner. The extra-thick case feels a bit cumbersome at first but quickly got used to it. Overall so far so good and this is going to be used a lot when I am unsure when I can next get to a charger.

Hi,
Any updates on batery usage?
Can one of you measure the adittional size with new battery in mm or whole phone thicknes?
I would like to buy the same battery, but I have a dillema. I bought HTC original car phone holder, CU S170 witch looks like this: http://www.mobilesupplies.nl/holder-touch-diamond-s170-with-charger-pi-8691.html
I wonder, if phone with this 1800 mAH battery will fit to the holder
Also is there big diference between this 3rd party 1800mAH battery and HTC extendet 1340 mAH.

The thickness is a maximum of 16mm (tried to measure it with a ruler so not the most accurate!)
Yep I'm in the same situation with the car holder, I've got the same holder as you but one that mounts on the car vent. With the extended battery, your device will not fit the holder as there is no additional clearance on the holder.
I think it will be a while until someone manufactures a holder with additional clearance (perhaps a spring loaded back bit) to allow for such upgrades.
Ive been searching for another holder but the only ones that seem to do the job would be the universal 'gripper' ones - these are very ugly in my opinion but currently I don't have much choice! May submit a new post in the section.
I've been using my device for almost a week now and the battery life is consistently better than the original one. Even if I seriously abuse it running different things it would still last be close to 24 hours.
I can't comment on the 1340 mAh.
THIS CAR HOLDER MAY FIT:
http://www.dsldevelopments.com/brodit/Holder/HTC+Touch Diamond-Brodit-Holder.asp
It seems like it has the extra clearance and in the description it states "this kit should accommodate all battery sizes". I wonder if any with a Brodit holder can confirm this? But looking at the pictures there seems like plenty of clearance.
Quite expensive though!

Thanks for reply,
I almost decided to by the original HTC extended battery, becouse of the thicknes, as I read it last about 50% more than original, so that should be bearible it's about two days Not compromizing looks of the phone that much!
Now there is still a issue with the car phone holder, becouse I realy like the holder I got, you can use it in horizontal posittion as a vertical. And I like the build and aesthetic look of it.
There is a small bumps on it, to fit the phone better, maybe if I remove them I can fit my phone with HTC extendet battery in it. Or maybe it would fit anyways without remowing them (picture attached)
As I read, the phone with original battery 900 mAH is 11.85 mm thick, and with extendet 1340 mAH battery is 14.40 mm thick.
So would be nice, if someone could post feedback with original HTC car phone holder, and HTC extendet battery. DOES IT FIT OR NOT

Like i said, I have the same mount as you and there doesn't seem like extra clearance behind. I would be surprised if the 1340 battery would fit even with the extra bit taken off, you need about 3mm extra. Plus you dont want it too tight so as it would scrape against the edges everytime you took the phone in and out of the holder. But see if anyone else replies I guess.
I know Brodit do two specific holders for the Diamond, one for the 900mAh and another for the 1340 mAh.

It's difficult to judge the thickness of that pouch just from the picture. I still have my mate's Touch Pro with me and it is about 2-3 mm thicker than my MDA C4.

Nobe question: I'm assuming that's with the 1800 mAh battery on your phone? lol!

[Q] ZeroLemon Samsung Galaxy S4 3000mAh Battery

I'm thinking about buying the ZeroLemon Samsung Galaxy S4 3000mAh Battery. Any opinions? I heard zerolemon was a pretty good company but I just wanted to confirm.

I bought mine about a month a go and I can definitely feel the difference in the duration of screen-on time. I went from like 4.5 hours to 5 hours roughly. More than worth the price.

thanks. I'll probably buy them then. 8.99 is a great price haha!

Bought my pair a few months ago. I don't remember the last time I actually plugged my phone into a charger. I just swap the batteries from the phone to the wall charger. I usually get about 15 hours of decent use, about 3.5 hours of screen time, out of each. It's a great buy.

Man i've tried emailing bastexwireless but they said they don't have any in stock.. still waiting for something i'll let you know if i find anything..

Does this battery add any bulk, size wise I mean, to the phone? I know the weight will probably be heaver but I had an extended battery for my old Photon 4G and had to go without a case on it because of the size of the battery. I don't want to have to do that but this battery looks promising from what I see.

maybe its matter, maybe not... but note that this battery do not have NFC chip.
i also thought about to buy that battery, but for me, the lack of this NFC chip is a deal breaker.

shop ?

U will perhaps find it slightly harder to put the battery cover on, but it will fit the same way as stock. Cases wouldn't be an issue.

They took nfc away so it can have a slightly higher battery capacity.

The battery very slightly bulges at the back. If you have a very very specific tight fitting case you will notice the slight inconsistancy. I had one that fit the Galaxy S4 specifically however once the battery was put in, it created a few mm gap.
I initially found the battery to add about 30 min extra however, it began to lose it capacity after a few months then became the same if not worse than the stock.
No NFC, bulge, same battery capacity wasn't worthwhile. I bought from bastexwireless and they were a pain to deal with so if you buy expect to make it a permanent purchase. I tired to contact zerolemon as well and they just gave me the runaround.

I would say the lifespan of holding its charge is pretty similar to the original samsung battery. Under heavy daily use, it would take abt 3 mths I reckon, for it to start losing its capacity bit by bit. It's just the way they are, so I would still get the zerolemon's since they are pretty cheap compared to samsung's. Over here where I live, the original samsung battery is only sold with the extra battery kit, and it costs abt 30usd. I alr got that so it would still be worthwhile for me to ship the zerolemon's over as I don't stay in the US.
Regarding bastex's customer service, I emailed them once regarding their poorly made wall charger. They responded pretty quickly and offered to send me a new one, as well as 2 new batteries since mine had alr bloated up due to months of heavy use. I guess the bloating issue pretty common. So maybe not all their staff provide quality support. [emoji41]

I just got mine this week. This is day 3 of using it. It seems to do a little better, but I'm still in the break-in phase of the battery. I like the extra weight, as it gives the phone a more substantial feel. It fits fine in my otterbox (defender series, I think). Haven't tested it in my seidio obex case yet. I used their battery with my Verizon Galaxy Nexus, and loved it. I expect good things with it.
I just ordered a single battery ($9.XX, with shipping). I didn't need the second battery, or that external battery charger.

Zerolemon's 7.5Ah batteries for Galaxy S4
Zerolemon's 7.5Ah batteries for Galaxy S4, I ordered 3 from e-bay with 2 chargers. The batteries are heavier than the phone and with case is more than twice as thick(deep) as original phone. Width and length are slightly larger too but not appreciably so. Big plus is am never tethered to wall and each battery will last 20+ hours of constant Internet use. Simply swap batteries after running it until <= 2%; one is typically always on charger. Phone with case/battery carries nicely in a LBT Holster.

The zerolemon wall charger is really low quality. It works (charges ur batt from zero to full in abt 4-5 hrs) for the first few weeks, and then takes longer and longer to charge.
Another alternative to never having to charge your phone on the wall is to get the official samsung extra battery kit. That charger is top notch. I got that and use it with my zerolemon's. So I don't need to deal with a huge bulky extended battery either.

It's a small bit bigger than the original battery. It makes putting on your battery cover a little bit more difficult, but not bad. I have a defender case and it makes it just a little tighter.

So far, my zero lemon 3000 mah battery isn't performing too great. I think I'm going to try and return it for another one to see if the ladder is better. I get about 4 hours of screen on time.
