Omnia 7 Replacement Batteries

The Omnia 7 uses the same battery as the Omnia HD (i8910)
So you can get replacement ones quite cheaply on ebay.
what I really want is a battery charger case...
you get them in Korea for other phone models but have yet to see any here at all.
basically it's a small case to carry your battery in, but it has a little port so you can charge your spare battery whenever.
it means you don't have to wait around and you always have a spare charged battery at hand.
this one is for the galaxy s

why can't we have stuff like this? it would make life so much easier!

ups wrong thread

That would really be cool.
But I am pretty happy with the battery performance...

i heard a lot of good thing about omnia 7 battery before buying it, but i am somewhat disappointed right now. it does not last me 8-20. God forbid if i played anything on the loudspeaker, when i'm say, camping.
i really hope the next mayor breakthrough in tech is in this area, instead of unnecessary quad-cores and whatnot.

I fully agree, I wish there was more impovement made in the battery field! I don't think there is a need to have processors any faster than 1Ghz. It's simply a marketing tool to get all the fools thinking that they have a better phone because it has a dual core processor etc. Now on a desktop computer where you will REALLY multitask (watch a video whilst photoediting, surfing the web and chatting on MSN) multi-core processors make sense. On a phone, there can only be one application in the foreground at any one time.
Anyway, I can confirm with the OP that the Omnia HD battery does work. I am using one right now!
Battery life for me is somewhat amazing! I went to a wedding where I must have played games for atleast 2-3 HOURS, then surfed the web somewhat, sent plenty of txt messages and a few phone calls. Lasted the full day, got home, went to bed, started surfing the web and the battery refused to die!
Whereas on other days, the battery tends to die quicker :S It's hit or miss sometimes.

Battery technology has definitely not caught up with smartphone technology. Many consumers are opting to an extended battery or a spare battery. Try batteries4less online.

Try mugen power

I grabbed the 1800mah mugen. It's incredible.
I'll spend the day with moderate surfing/news feeds/gaming and often I'll be at 50-60% battery. It's ridiculous I almost don't believe it.
That being said, it takes hours to charge via USB (from almost dead to full takes approx. 9-10 hours.)

What about this 2430 mah battery:

if you scrape the cover off, it's 750mah inside.
go for oem, all the rest are fakes (esp china ones) and the genuine ones like mugen are 200% more expensive than oem ones for marginal benefit.
my omnia was suffering from battery issues and i realized although the phone is new, the battery was old, so i bought a new one from amazon for £7 inc shipping. has worked fine ever since. normal days usage, 1hr of calls, 2 hrs browsing, 1 hr texting and the occasional game and i have 45% at the end of the day when im recharging. i have two email accounts on push, location on, wifi on.

Question about the Mugen Batteries
Whew, first post! Anyhow, I have seen the Mugen batteries listed previously for other phones I have used. I've always been curious, but never brave enough to pull the trigger on one. Is anyone aware of any battery draw-down tests involving their products? I'd be curious if someone were to use something WP Bench's battery drain test to get a valid comparison of the standard 1500mah to the extended 1800mah cell.

After about a month's use I can safely say my phone has yet to fully drain.
I do charge every night, and often the charge floats around 50% after a full day's use. I surf quite a bit (on wifi), play some games, etc. I admit though, that since getting Mango my Omnia doesn't grab 3G as often as it used to (it's usually on EDGE). This is a known issue with Mango, so I'm sure I'd see heavier drain if I was on 3G all the time.
Since I bought the Mugen day one, I can't really compare it to the stock battery. I too, would be curious about WP Bench drain tests. If I have some time where I don't need my phone, I'll try it out.

Anyone had any experience with this site?

claiming they have 2400 batteries for the Omnia 7 for £25...it doesn't look as obviously fake as the ones on eBay, and it says they provide a warranty ect.

Im looking for a genuine samsung battery for my omnia 7, mine came deffective, does anybody can tell me a trust website? thanks!

mugenpower 1800mAh drain test
I compared the 1800mAh mugen battery with a stock (about 8 months old).
First you have to go through several discharge/recharge cycles as they recommend.
using WP7 Bench Battery test :
stock lasted 3:48.49 (225mins)
mugen lasted 4:35.52 (275mins).
So an improvement of 22%.. which is what you would expect if the battery really had 20% more capacity as advertised.
at USD$46 these are not cheap, but the phone now lasts a complete day with my typical use, and it didn't use to - so to me it's worth it.
BTW the delivery from the official site was free and quick (under a week)

hummmmm

"Free extended cover included" do you want to make the phone any bigger?

By what i read on others forums, the 2400 mAh is a fake, so the 1800 mAh's Mugen is simply the best choice.

Akku-King
I bought "Akku-King" 1750 mAh in December and it works fantastic. In "normal" use 2 days.

My first battery replaced by manufacturer, capacity 1500 mAh and it lasts 12 hrs fully internet used.

Mugen battery - a dud.

First of all let me say that I don't know if this is a one off - or what the customer service is going to be like.
However, I thought that I would flag this up straightaway because I know that lots of people seem to be talking about ordering these very expensive batteries as an answer to DHD short battery life problems.
I waited for about 3 weeks for delivery of this 1500ma battery which I ordered directly from the Mugen site.
It arrived today but it is clear that it is faulty. It won't hold its charge. It has been on mains charge with phone switched off for about 8 hours and now the widget tell me that it is only about 25% charged and going down pretty fast.
I've emailed Mugen and I'll let people know how they respond

Woke up this morning to find an email from Mugen telling me that they will send me anolther one.
No word on whether I had to return the dud. I emailed them to ask them.
Anyway, so far so good.
Quick response. Hope that I don't have to wait for the replacement as long as I did for the first one.
The dud battery doesn't do anything now. No charging lights - nothing. Completely dead.

Just had an email asking me to send back the original. A bit of a nuisance. I kow that it is entirely correct that he should be sent back the original but for these prices the batteries shoujld be tested, the transaction should be straightforward and a pleasure.
So far, it is all frustrating and a nuisance
Nothing has been said about refunding me the cost of the battery to HK.

Thanks for informing us. I was wary about ordering one of these. Please let us know if the replacement is better.

Well, **** happens in mass manufacturing - but it's good to see they are responsive.
I'd say the minimum expectation is that it performs the same as the stock battery, so it'll be interesting to see how the new one is.

well I would hope that you would perform better than a stock battery. It is very expensive – and about $46 and I had to wait nearly 4 weeks for its delivery, and then I had to ask for another one and I'm still waiting.
I managed to buy replacement stock batteries for less than $20.

and also, I don't know if I'm going to get back the cost of returning the dud.

I can't see any 1500mAh batteries for HTC Desire HD on the mugen website, do you mean their 1300mAh battery?

No. 1500
*******

Hello all,
A link for 1500 ?

Great news. I've received the replacement battery.
No word about reimbursing me for the postage costs for sending the dud back though. However, it wasn't that much and if this one works well, I'll be happy.
It is on charge and seems to be charging up well. I have no instruments to measure it so I will simply have to let people know my impressions as it goes along.
It is a 1500

I have one also. Definitely a 1500. My current full charge status is at 88% after 5 hours, and the screen has been on for 2 hours. It's had its cycle of at least 5 full charges (recommended by Mugen), and the last time I put it on the charger was at 15% after 36 hours, and just under 5 hours of screen on time. My screen brightness is not really low either. I have it set at 60%. I'm very happy with it.
http://forum.xda-developers.com/showpost.php?p=12085610&postcount=269

could you please provide a link?

So far this battery looks very promising. It hasn't been through several cycles yet but it already seems to me to last longer than the stock battery - which had been recycled at least 40 times

Can you send me a current widget log of a full charge cycle once you condition the battery? I've calculated the OEM battery capacity of a 6 months old battery and it's 1121 mAh. That is the usable battery capacity (who cares if there is still some charge in the battery if the phone can't use it?) so it would be interesting to see if Mugen made anything better.

Looking forward to hear some news

Sounds promising. Strange that they pulled it from their site and someone else mentioned they are releasing this mid-April now.

Hi Guys.
I just wanted to show that in the past I've had very good dealings with Mugen Power Batteries.
You can read this post from a couple of years ago. The phone and forum were different. The Sales person after I asked him via email - even promised me a spare replacement cover, (so 2 new covers) one which arrived separately some time later.
Nothing but a great experience for me as a company and they clearly step up to the plate.

possible to get a link for the 1500? I find only the 1300 on the mugen website

Anyone bough both the Anker and Chichi batteries for their Sensation?

I don't know which one to get, so based on your experiences, were they worth it?
Has anyone bought both and gotten better performance on one more than the other? Has anyone gotten either of these and actually have had equal or less battery life compared to the stock battery?
thanks for any helpful replies!

I'm wondering about this too. Judging from threads from both brands, alot of people are getting the anker as they are cheaper. But according to some users who have used chichi are saying they last long and have had great experiences with them despite being $20+. Any one else can chime in?
Sent from my MB860 using XDA Premium App

Yeahh. I had a chichi battery for my G2 and it worked wonders so Im leaning more towards it.
Sent from my HTC Sensation 4G using XDA App

I bought both...figure I could use one for a back up if anything but both seem to be getting good reviews..the CHI is on the 2nd cycle, i got 10 1/2 1st one under heavy usage would only get about 8 hr at most under heavy with the stock.
2nd cycle i was at 14 hrs under semi heavy usage, before I feel asleep when I woke up it was dead so not sure how long it actually lasted.
3rd cycle starting today..
The Anker is in the mail so hopefully it will arrive soonL
Having both I would prob go with the Anker since its cheaper and the reviews have been very good as well, I purchased the ChiChi when the Anker was 60 now that its back to $10 I would just go with those
Either way I'll post a comparison when I get both although I don't think there will be a huge noticeable difference, seems like both are excellent batteries

I just won two chichi batteries + charger for $15 at Ebay. what a good deal.
will test once i receive them.

I feel like there won't be much difference either, but I'd still absolutely love it if you could give some side-by-side specs.
Also, one nagging question from the Anker thread, if you have access to a scale, would you be able to compare weights between the stock, Chichitech, and Anker?

subed, also want to find out what the life difference between the 2. But i don't think you can go wrong with either one right? because they both will last longer than the htc one...

Will weigh both ,I have a scale...just not sure if I can find it, didnt come in the mail today hopefully tomorrow or mon which will let me fully cycle the ChiChi ones

My chichitec lasted 25 hours first charge with moderate usage. Not heavy, but definitely not light usage. Moderate till about 6pm then heavy till around 11pm. Then it was in standby the rest of the night. The stock battery would have never come close. I ordered an Anker too since it was only 9.50. Waiting on that and my battery charger dock still. Got the battery and used the phone for a few hours without charging it. Started at 70 got down to around 30. Then I turned my phone off and charged it for about 7 hours. Got up at 6am, unplugged and turned it on. Lasted all day and all night and died around 730 the next morning.charged it for about 3 hours on my laptop at work today till it was full with it on. Going to let it drain completely again on this charge. Stoked.

Can anyone post a link for these batteries, tried searching didn't come up with any results thanks in advance

I have both on the way. Waiting on slow shipping heheh. I'll let you know!

Is there a need to peel off the sticker for Chichitec ?? I remember having to do this for my G2 and it had to chip lil bits of the plastic off for it to fit and not bulge out lol

Extended Battery

I've seen some Anker 2400mah batteries for the EVO 3d, but seeing how they're the same I would've thought there to be the same for a sensation but with a different back cover.
I can't find anything like that, if anyone can, please let me know.
Also, isn't there an official HTC extended battery like the hd2 one for the sensation?

Bump .... ... .. .

If i'm not mistaken there are many types of extended battery for the HTC sensation that do not need a bigger cover. First you have the popular Anker Batteries.. This is so far, to me, the best extended battery as it greatly improves the battery life of my sensation. What used to last me half a day with 3g on, now lasts me about 13-15 hours. Hope this helps.

Hey mate have you tired ebay? I got one for my sensation paid 10gbp and it last over 48 hours with listening to abit of music and texting and talking. its a perfect fit and it hasnt even got close to being warm.

I have the Anker, but it doesn't last me more than about 6-7 hours, and this is with it underclocked; granted I do use it a lot, but that's why I'm looking for a better one that's thicker than the oem batteries like anker.

I have looked on ebay, but I haven't seen batteries with higher mah's like 2400mah or more. I don't mind having to put on a thicker case, but there doesn't seem to find any for the sensation - there are more for the EVO 3D eventhough they use the same type of batteries.

Hi guys I need help to find a good solution for my sensation... actually with stock battery, display brightness set to 40%, CPU set to 1290 MHz and 3g connection on, I get only 4-5 hours of use... I need somethings that help me to reach at least 10 hours of intensive use without paying over 15-6 €… What you suggest? I'm thinking about:

I've read that this is produced by the same company of anker battery and that this has the same quality of any anker battery...
3) any anker battery pack with 1900 mah, but price is about 20 €...
what do you think about the first? The second should be better? I need to stay about 15 hours without charging (5 of intensive use and 10 of moderate use)... I also want to buy a separate charger for the second battery, but I'll take it from hong kong and delivery time is about 30-40 days...

The gold batteries are terrible, the saner and anker (chichitec too in US) are the best choices.

The gold one is crap - I bought it and it was only 1500mah - the seller is a scumbag too. When I sent proof it was nowhere near rated, he said he could refund me half, and then tried to negotiate from there claiming it is not his fault. He refused to edit his listing nor acknowledge others who had the same issue (see his feedback). I had to bully him into a refund by threatening negative feedback and a paypal dispute.
It seems there is only one option with a replaceable back cover, and it is Mugen $100~ and gives poor reception since there are no antennas on the cover.
You may want to investigate the powerskin, although I don't care for the inability to transfer data via usb while it is on, nor the shape. I do miss my EVO 3D + Extended battery.

What battery should I buy?

My stock battery is shot. It will drain from fully charged down to nothing in an hour of browsing the net. I have tried everything to calibrate it and have tried different ROMs but still the drain is horrible.
I saw a 1900 anchor (ankor?) battery on amazon for $19. Is that the one that everyone buys?

Yes. http://www.amazon.com/Anker-1900mAh-Battery-Sensation-Mytouch/dp/B0053EZJMC
It works great. Though l don't use my phone heavily. I mostly use it at home when phone is plugged in. But still it last much longer than stock.

Most people buy Anker battery and are very happy with it. I personally wanted more juice so I bought Mugen 3800mah battery. With Mugen I get with extremely heavy use around 26 hours of use. With moderate use I get around 36 hours. Light use 48 hours. But one problem with mugen is you will have to replace your back cover and your phone will be thicker to accommodate the battery. For me personally, I was after extreme battery life so the thicker phone didn't bother me at all. Another issue is price. Mugen is five times more expensive than Anker. But for me, I'm keeping my phone for awhile so it was a investment. But most don't want to deal with those issues so they choose Anker. It all depends on what you want. I recommend you start with anker, then if you decide you want more juice, go with mugen. But for most Anker is just fine. It's a good battery and will give you extended use. If you want extremely long battery life, go with mugen.

This is probably a stupid question but you can charge the battery by plugging your phone in like usual right? I see that some of them come with a wall charger where you have to plug the actual battery into that.

Thanks for the response but I think that is a little overkill. I will probably get a new phone before that kind of price is worth it.

Yes. Anker simply replaces your stock battery. Same shape size.

Is this Anker really that good? Beacuse I always buy the batterys from ebay (just like the ones for my DSLR) and have now a no brand 2430mAh using for almost a year and can use it a whole day without problems. Costs me only $12 and free shipping.

I bought 2 Anker batteries and a charger for $30US, I think. No regrets.

I bought my Anker 1 year ago and it still pretty good!

Get Anker.
An important thing to consider is anker has a 1 year warranty. And they WILL honor their warranty. I bought 6 batteries for my families LG Optimus Vs (Our first smartphones) and 1 battery went bad after like 6 months. I called them up a few months later when I realized I had a warranty, and they sent me replacement! (it was like 1 month before my warranty ended) And all they wanted was the serial numbers of the old batteries, however the original ones didn't have numbers so they instead just wanted a photo. (Which now that I think about it I never sent... ...)
Also, one of the chargers (that I bought with 2 batteries, a few months before that set of batteries I mentioned above) fried for some reason after about 8 months. So I left it on the shelf hoping I might be able to fix it. By the time I realized I had the warranty it had been over a year since my purchase. Bummer. So I called them up explained it went bad several months ago but I didn't know about the warranty, could they send me a replacement? And even though I was no longer in my warranty they sent me a new one.
Another thing is, for me, having spare batteries is a MUST as I have a LOT of free time at work. (I'm a background actor, and most of the time we have to do whatever we want) And continuous use (Browsing the web, playing games, reading news, watching TED AIR talks) drains a battery in 3 - 5 hours. And it can sometimes be 16 hour days, with no place nearby to plug in a charger. That's another awesome thing about Anker sets, the stand alone charger. I have MANY times been at work with one of my batteries dead. I looked for and found an outlet, a little far from holding, (where we are while we aren't working) and just plugged a dead battery into the stand alone charger and into the outlet. I can go to work or just go about my business not tethered to the wall, and 3 hours later my battery is charged. I then would switch one of my more drained batteries for it and continue like that.
So ultimately its up to you, but I would recommend getting a set of 2 Anker 1900mah batteries and a charger for $30. However if the charger isn't a big deal for you then look up some $7 Evo 3D batteries on Amazon. They are 1730mah, and are pretty decent.
Bragging here, I currently have around 10 batteries! Only 2 are anker. the others are 5 EVO 3D and 3 Sensation stock batteries I got for only $2 each! I found someone on Amazon selling them for $2 each with $4.50 shipping, only the shipping combined! So I got 8 batteries AND five 16GB Class 4 Sandisk MicroSDs for only $54 total. What a deal. lol.
