HD2 Lithium Polymer Battery On Ebay!

Well guys, this would be a first:
http://cgi.ebay.com/Htc-HD-2-batter...311?pt=LH_DefaultDomain_0&hash=item3cb4d8f5af
But hold on though. It almost looks like a plain old re wrapped Li-Ion battery. The guys feedback makes me skeptical, too. Looks like he's new to Ebay.
Thoughts?

I believe its the same old crap. They say its 1600mA. But in reality even worse than standard 1200 mA. Price talks for itself.

You know I see alot of talk about these 1600mah batteries from Japan and alot of speculation, but I have never seen anyone do any real world testing. I was planning on buying one of the 1600mah batteries and doing a setcpu stress test on it as well as the stock battery and record the results of how long it took each to fully discharge.

Do it! If you become the guinea pig and the battery is indeed better, then you would be a hero in these parts lol.

The last battery I bought was a 'genuine' htc 1200mah from an amazon seller, turned out to be a fake that was obviously not htc.
Be careful with testing unknown batteries from unreliable sources, the fake one I had got very hot and was a poor fit into the phone. These phones are very temperature sensative and you would not want a lithium fire inside your HD2!

So is anyone willing to do some battery tests? I would be so happy if I could use a 1600 mAh battery and not need one of those huge, bulky battery covers.

You should be very careful if you try a battery from an unknown or not certificated source. I read about many cases, where people bought some cheap batteries which turned into a little bomb, because of some reason. and i don't know if i want to end up in a roll chair for my whole life just because of a 20€ cheaper battery. A battery can damage your phone not only by heat. Such batteries have also some extra hard- AND software for controlling purposes integrated and if there's a problem, it could cause other problems in your phone.
The normal 1230mAh battery is not very bad, one day for such a huge display and some other features is enough. and if i have to go to the jungle and can't charge my phone i will buy the bigger battery and won't mind about the thickness of my phone ^^
Just my thinkings

I actually can confirm, I can go with my phone with minimal to moderate use for several days. But when I am at work and playing with it nonstop - 4 hours maximum. That is why I got myself a GTMax battery

I would also agree with this statement. None-the-less, I ordered one of the 1600mah batteries yesterday. We're gonna have to wait a few weeks for it to clear customs however before I can do any testing.

Not the first...
I have the andida 1600 Ma and it is labeled as Lithium Polymer.

I bought a 1600 mAh labeled battery from eBay which came with very good packaging and even a tin case. The labels on the sticker make it seem fancy and trustworthy. However, in my experience comparing that battery with the stock HTC 1230 mAh battery, there is no increase in uptime. On Aondroid both batteries read 1230 mAh. Even though the 1600 mAh battery claims to have that capacity it really does not. I even weighed both batteries on a scale. The 1600 mAh Li-on battery weighs less than the HTC original battery.

It's not possible that a stronger battery is as big as the stock one. most of these people only put another label on a stock battery (or rebuild battery with the same power) and sell it for a higher price. I'm sure you won't get a Li-Ion battery with the same size as the stock one but stronger. With a Li-Po battery it's makeable but not easy and they'll have a higher price because of that.

The price makes me suspicious as well. I don't notice a lot of difference in device up time with my Andida battery, but it is still new and it may increase as I get past those initial cycles.
... if I don't reflash more NRG ROMs! They give strange readings for the first few battery cycles after a flash. I just flashed one yesterday, so it will be a while before it settles down.

The Chinese knockoff battery got here today. We're about to find out if it can hold It's own once I put it through the first few charge cycles.

It's sad that I'm able to get an 1800 mAh battery for my G2 that isn't appreciably bigger than the stock 1300 mAh, but there's nothing equivalent for my HD2.

Can't you return it. There should be eBay's buyer protectiontion just say buyer gave you the wrong item

Is there an "extended" battery the size of the original?

Are there any batteries for the DINC that are the size of the original but have a higher capacity (if thats the proper wording for it)?

most people use the oem htc 1500 batteries... they are only 200 mah bigger but it add a decent ammount of life to your phone... I have both the seido 1750 and the 1500 and the 1500 last just as long as the 1750... they are only like 10 dollars also so might as well get 2 on amazon... I have bought this battery for lots of people I know and it works great

I've got a 1750 Seido on the way from Amazon. They say you have to charge and discharge it a few times before you see the extra hour compared with the stock battery. We'll see!

I have seen those reports too, don't believe everything you read.
I had a Touch Pro 2 before this and the standard battery was a 1500mAh. I had the Seido 1750 for it and it was a lot better than the original battery.
When I got my Dinc I was using the stock TP2 battery for a while and then I bought the Seido 1750 for it as well. I have no regrets, in my opinion it is a lot better than the 1500mAh battery.
The way my phone is set up and the way I use it, with the original battery I could rarely make it through a full day without having to charge it.
With the 1500 by the end of the day I was about done (anywhere from 15% to 25% remaining.
With the Seido at the end of the day I have between 30% and 40% remaining.

Buying that battery now. Hopefully it adds a little boost in battery life

I bought the battery mentioned in this thread and have been getting great battery life. Right now I am at 21 hours with about 17% left. Prior to this I was unrooted and having to recharge every 8 hours on the stock battery. Definitely recommend it but the best improvement to my battery life occurred after I rooted.

It's a bit of a tight fit, right? I just received mine and it seems a bit tight.

It's a little tighter, but not too bad. I am loving this battery so far. I'm definitely getting good life out of it.
I listen to music on my 1 hour commute and when I'm at work, my battery is more than 65%. Before it was in the 30s.

Flip it over and squeeze along the edges, working from the camera end to the bottom, making a firm connection as you work down the edges. After a few times things settle in and closing the back is no challenge at all.

Yeah that's how I have been doing. Been off the charger since 6 AM and there is still a good amount of battery left

Yeah I bought the battery linked in this thread and its been worlds better than the stock. I'm at 27 hours since my last charge, with wifi and Bluetooth always on a few calls and about an hours worth of robodefense, I still have 18% left. Skyraider could have something to do with it but the battery is well worth the investment and the snug battery cover fit was fine.

Battery has been treating me well I must say. I tethered a bit and it didnt drain that much at all. Not sure on % 's but it wasnt like the original.

So looks like I may pick up one of these, thanks guys.

I bought this battery a couple weeks ago and it pretty much crushes the stock battery. It costs more than the one on amazon but its great. Quick shipping too.

Mugen Power Batteries

I though I share this site with those who don't know.
Mugen Power is a reputable aftermarket battery manufacturer, and you will find many good feedback, reviews and recommendations about Mugen batteries on XDA.
The main site is here: http://www.mugen-power-batteries.com/
I am myself a Mugen product user and I would like to share once again how amazed I am by their customer support and social network persence, like for example if you follow up Mugen Power on facebook http://www.facebook.com/MugenPowerBatteries, they give 7% discount on their stuff. Many fans on facebook represents brand loyalty to clients, and you can see many fan comments and simple questions which are answered accordingly. If you have problems with you battery, it drains quickly, it charges slowly they exchange without questioning. Worldwide shipping is free of charge. Overall it is worth noticing.
Concerning Verizon Moto Droid Bionic Mugen has 2 products:
Its a 2000mAh Extended Battery, it fits the original cover. Slightly more powerful than original just enough to resolve the issues that might accure with factory battery.
And for extra power there is 4000mAh Extended Battery which enlarges the phone with an extra replacement backdoor, but improves the battery life at least 2.5 times.
I hope this little review will help you in your quests for battery replacements.
For questions, ask their facebook or write directly on their site, I always got my responces there so far.
I have ordered myself the 4000mAh battery for testing, and hope to post user experience results as soon as the battery arrives.

If you could, let us know if that battery will fit under the OEM extended cover. If so it would make a nice upgrade.

that is exactly what i was going to ask. let us know please

I purchased the 2000mah mugen and it does fit under the OEM door.
Battery life with it though was actually less than the stock for me.
At times it would get really hot and just drain out when in use.
I keep it charged and use it as a spare in case I need it when taking long trips.
This is just my experience with it. Yours might be different, but as of now, I don't recommend the mugen 2000mah one.
Haven't tried the 4000.

That should not be normal. I had same sort of negative experience with my other phone (galaxy nexus); i have written Mugen about it and got my apology and warranty replacement without questioning that is why i have mentioned my total respect to their customer support earlier.
If your warranty is still valid you should definitely write them a note about your problem, maybe they will help you with how to root it or something, try this one:

@mercdoc and @Noob_In_Recovery
the 2000mAh version fits in original backdoor as @dellenrules says
and the 4000mAh is a big one, it shall arrive with extra backdoor to fit in the phone, i cannot wait mine to arrive!!

The mugen 2000mah battery in actually should last longer.
Because of how it's designed, it gets hotter quickly. As a result, it kills the battery a lot quicker.
When ever I get a phone, replace the battery with a mugen.
When I'm working in the office, it's pretty much "death by AC." My phone can last me all day with no problems.
When I'm on the road, at the gym, or any place where it isn't cool, the battery dies quickly.
No it isn't just a bad battery. I purchased 2 and they both behave the same way.
The stock battery is better for me since I'm not always in the office. I use the mugen as a backup and keep it charged and ready to go when I have to take those long trips.
I already get about 15 hours our of my stock battery on a single charge.
Not too worried about battery live at the moment.
Thanks for your concern.

Mugen Power 3600mAh Extended Battery for Samsung Droid Charge / US Cellular Samsung G
Comments of Mugen Power Battery from Facebook user Anlyn Bankos:
HLI-i510XL 3.7V for Samsung Charge: This battery was a complete waste of money. It was a gift and my dad seriously over paid for a battery that won't hold a charge. It's to the point where every day now I have to plug my phone in during the day b/c my phone says "battery low", I plug it in and "wow look at that - I'm charged to 100%". Imagine this happening 5+ times a day. I can't be without a charger because if I can't plug the phone in immediately, it dies. If I do plug it in, the battery miraculously recharges to 100% in mere seconds, only to go through the whole charade again 10 mins after I unplug the phone. I have dug out the original battery and am going back to that. Crappy product.

Thanks for the site information, good news for the facebook discount too, i did not know that.

I bought a Mugen 2000 mAh battery about six months ago. During that time it worked great, average time 16 - 18 hours according to Badass Battery Monitor. (For comparison, my standard 1735 mAh battery lasts about 12 hours. I mainly use WiFi and 3G, turning on 4G only when needed.) Then last week, the Mugen started falling off a cliff. It would go from 80% to 40% instantly and then drain to 0% in just a few minutes. This happened again and again. Finally I asked my wife to test it in her Bionic, just to rule out problems with my phone, and sure enough it behaved the same way with hers. So for $50 I got a decent increase in battery life but it only lasted 6 months. YMMV of course. Now I'm using the stock battery again and getting the standard 12 hours. I ended up ordering the 2670 mAh extended battery from VZW, which is currently on half-price sale for $25. It should be here tomorrow. Probably won't order from Mugen again in the future.

I love my 2750 extended battery.

eCell extended battery

I recently bought one of the eCell Gold 4500mah extended batteries from Amazon. When I looked this morning they were no longer in stock. It is an extended battery that uses the stock battery door. Just barely. It is a very tight fit. But I had my doubts as to it really being 4500mah. I just finished my 3rd charge cycle on it and I must say that I am impressed with the results so far. The majority of the screen on time was using FBReader to read a book. I also did some gaming, interenet browsing, texting, and made a few phone calls. I don't know how long it will hold up. I will report that after a month of use.

Does NFC work?

Is the battery physically larger than the stock one? If it isn't I doubt it's 4500mah...as many "gold" batteries claim much more life but use the same size.
Could you post pictures of this battery side by side with the stock one?

Do you have a link to where we can get one?

I don't think you should trust that "Battery Management" app to actually give you the capacity for the battery you use. In that app, you actually type in 4500 mAh for what you think the capacity is and then the app just estimates drainage around that number. It's not reliable to measure the mAh for a battery this way.
From looking at your Android battery usage breakdown, it doesn't look any different than what a stock battery would do. Your on screen time looks particularly low for a 4500 mAh battery should provide and looks in line with the battery stats in the battery stats thread where people use stock 3100 mAh batteries.

Don't know about NFC as I don't use it. Physically it is slightly larger than the stock battery. I don't know where you could get them now. I got mine from amazon. As far as the capacity, I doubt it is much better than stock but for me it is getting about the same or a little better on screen time as my stock battery did. Maybe the stock battery I got wasn't that good but I couldn't get 8 hours of screen on time from it. The eCell was only $20 so that is not a bad price. For a gold battery the performance is pretty decent.

Do Not Buy "Gold" Extended Batteries

I want to save people here some time and money and let them know those "Gold" slim extended batteries you see on Ebay have false and misleading capacities. The stock battery that comes with the Galaxy Note 2 has a 3100 mAh capacity. There are many "Gold" slim batteries on Ebay claiming to have 3800/3850/4000/4150/4200+ mAh capacities in the same size as the stock Note 2 battery.
This is a lie. I got one of those 4200 mAh "Gold" slim batteries from an Ebay seller in the States with a 99.7+% reputation with tens of thousands of previous sales. It also costed me $20 because I thought that it could be legit. You can get these same batteries from other sellers for as little as $10 each.
From doing previous web page battery draining with the stock Galaxy Note 2 battery, I know that I can get about 1.5 hours per 10% charge using Opera Mobile on wifi and with the brightness turned all the way down. With this 4200 mAh "Gold" slim battery, there was no difference in performance. I still only got 1.5 hours per 10% charge even though the "Gold" battery is suppose to have a 35% greater capacity.
I'm tempted to peel the "Gold" label off this battery and see what is really underneath.
In conclusion, don't believe any of those "Gold" battery claims. Don't buy them. Stick with stock Samsung batteries.

Enough said.
