HongDa Power 3600mAh Samsung Galaxy Nexus battery

I have one of those HongDa Power 3600mAh extended batteries for the Galaxy Nexus GSM... I'm a noob so I can't post a link to it, but they sell them as "hongdapower799" on ebay.
It's a 3600mAh extended battery for the GNex GSM version made by some company in Hong Kong. Battery Monitor Widget Pro estimates it between 2600-2750mAh, which is a nice, big improvement. I definitely notice an increase in life. It sucks that we can't get the Seidio 3800 battery with GSM, but at least we have something.
Does anyone else have one of these? What kinds of estimated mAh values do you get in Battery Monitor Widget?

Oh yeah... Also, has anyone tested this battery out with the Seidio extended Surface case designed for use with their 3800mAh battery? I ordered one and I'll test it out and post the results here, but if anyone has tried this and failed, I'll just send it back without opening it, lol.

I can't find this Hongda Power battery.

Here is the ebay listing for the battery:
http://www.ebay.com/itm/New-3600mAh...Nexus-Google-Galaxy-Nexus-i9250-/260921234182
And here is the listing for the Seidio case:
http://www.seidioonline.com/samsung-galaxy-nexus-surface-extended-case-black-p/csr2ssgnlx2-bk.htm
I have confirmed that the Seidio case is indeed a PERFECT fit with the phone containing the Chinese battery. Like PERFECT. And the battery is consistently rated at over 2600mAh. Not only that, the battery was a replacement for another one I got from HongDa which didn't have great capacity. The guy sent me another without charge. This combo is definitely recommended for anyone who wants to get more battery life on a budget!

So, if I understand you correctly, you got a battery with really poor capacity followed by good customer service and a replacement battery that consistantly achieves ~70% of it's rated capacity. And this qualifies for a high recomendation.
I'm not suggesting anything bad (or even out of the ordinary) regarding this seller or this battery, but I think that as consumers we've become far too accepting of battery shenanigans all around.

Just curious. How did you determine that it is rated at ~2600mAH (which is 25% of what it is advertised at) ?

Has anyone tried one of these cheapo ebay extended batteries?

Found this extended battery on ebay, was wondering if anyone on here has tried it, i know it looks hideous, but if you know your making a trip somewhere it could come in handy if it works the way its supposed to. Its cheap as hell too.

9 bucks... can't be too great,
but what can you lose? lol

Seems to me that if the larger aftermarket brands have trouble meeting the stated mAh rating on their batteries, what more of unbranded ones that goes for an even lower value?
I also still have very clear memory on exploding phones from third party batteries years ago

I bought a cheapo 3800mah and it lasts barely longer than my stock extended battery. I wish samsung made an official 3800mah version

Buy 2 stock batteries and solder them together. Works great.
3500 real mah. I didn't think the 2000 extended batteries would fit under the cover from the Hyperion I had here. I agree though, if I can solder it up in an evening, Samsung certainly could work up something.

hopefully more phones in the future will be like the razr and give us a factory extended battery closer to 3000mah.

Razr maxx when I had it for a week was sick! Hard use all day, charged every other day, seriously insane battery life. If that phone ever gets bootloader unlocked, I would be all over it again.

Have you done this solder thing? Any tips?

if you look at the battery in the phone you can see that there is some space at the top of each terminal, use this space to solder a fine piece of copper wire to a second battery. make sure to solder the batteries in parallel, positive to positive and negative to negative, to retain the same voltage.
i remember taking apart a so called 3500mah battery from ebay and they were just two cheap 1500mah batteries tapped together. Apparently in china 1500X2 is 3500.

Why does everyone want extended batteries? 99% of people have access to a power cord most of the day and just don't need it. Granted, I'm new to the phone, but I really hope I don't need to carry around a huge battery or two. Personally I'd rather charge it more often. Just my own opinion.

I bought a 3600 mAh extended battery for a few dollars on ebay. Despite the fact that it makes my phone look like a beached whale, it totally got rid of my power shortage anxiety. My most useful ebay purchase so far..

Even If it's 1500 that's still 3000mah for less than $10. Pretty good deal.

they start loosing capacity after the first few charges and became unusable after 3-4 months.

As long as you know that I don't see a problem. Spend $10, use it for 6 months, buy another one. Much better than spending $100 for a mugen.
Even the Samsung batteries lose their capacity over time.

Seidio 3800 mAh Extended Battery vs Battery cover case

Welcome.
For some time, I looking to buy extended battery, because the stock battery works for me too short.
Already considering increased battery 2000 mAh Samsung, but that does not give too much more than stock.
The second idea was the Seidio 3800 battery, but this expense is getting a bit too big.
And the third idea is to External Battery Case.
Cost is much better than the Seidio, and if I'm counting (2200 mAh Extended Battery + 1750 stock battery) it even gives you more energy.
Can anyone use it already?
How is it exercised?
It seems to me to work like as a charger permanently connected, so it is not an additional battery, but charger, which is non-stop charge the battery.
Do not destroy / reduce battery life?
And did this significantly increases the size of the phone?
Is it possible to choose the cover?
As for the Seidio, a little do not succeed in choosing the right kit.
The manufacturer's website there are several, and I myself do not really know what they are different.
I need one that will enable me to mount the 3800 mah battery and attach the phone to your belt.
Thank you

I have had sedeio extended batteries before and they where great. I have also has a charger case it was powerskin brand but I must say it sucked. The charger case I had made my phone really hot. I'm planning on buying the extended battery and convert case since I need battery life and protection. And I believe it comes with a belt hook

I got the Seidio extended battery too. I also have the case that comes with it. It's big but it hasn't been a problem for me since it eliminated the charging-all-day hassle.

[Q] Best battery solution without extended battery

I've been trying to find a good solution for when I need alot of battery power.
I found these on ebay:
2300mAh battery
http://www.ebay.ca/itm/2300mAh-Batt...341204?pt=PDA_Accessories&hash=item19d1945354
2800mAh external battery charger
http://www.ebay.ca/itm/Black-2800mA...649840?pt=PDA_Accessories&hash=item4167480eb0
Since the standard battery is only 1500mAh, I should see an increase from the 2300mAh battery, but I don't know how much.
The second one seems like it would give me even more, just with the downside of having to carry it around when I think I'll need it.
Any ideas?
I just don't want to give up my Trident case.

both fake chinese lies. biggest standard size is mugen 1600
. however its about 1/2 mm bigger than Samsung stock so if you want to combine with wearable jacket batt.
best value are deji. I can send you one for £15. the cheaper ones are crud. another trick is lying on the %

I agree, I wouldn't trust these. If you can afford it, Mugen batteries are (from what I've heard) good, and they have one that is 1800Mah that'll fit under the standard battery cover.

Largest capacity battery without extended case?

Hi, I was wondering what the highest capacity battery was without having to replace the back cover?
I know of the anker 1900mah, what about the Samsung 2000mah? Also, what do you guys think of buying no name batteries that are advertised as 1900mah?
I've bought no name batteries for my HTC incredible s before, I bought an 1800mah battery which gave me the exact same battery life as a 6 month old stock 1450mah battery, so thoughts?
EDIT: I'm a stickler for thinness so even if a back plate adds 1mm to it, i don't want it, I've had enough of my thick as stars HTC incredible s

the samsung 2000mah battery gives you a new back cover and makes your phone a little bid thicker, but not much. Most hard cases will still tightly fit
This would be your best option, as you are sure it will be 2000mah.
I myself got the 1900mah anker battery and dont really see any difference with it... It is about the same as stock. My 2000mah battery is arriving soon ^^
There are enouf pictures/movies of the 2000mah batter, there you can see how big it is I myself think it will make the phone easyer in the hand

Do instead of it having a bulge at the bottom, now everywhere is as thick as the bulge?

yes!
I only get 2.5 hours screen on time with data most of the time off with my 1900 anker battery, which is same/worse than default battery.
I think your safest/best choice is the samsung's official 2000mah battery. Do know that many slim cases wont fit anymore.
You can clearly see the size here:

Oh yes, since I'm getting a slightly bigger case along with the 2000mah battery, why not get something with even more capacity? What's the largest capacity that will fit in the back plate that comes with the 2000mah extended battery?

2000 mah
You can buy even bigger ones, but they will be 2-3x bigger in size.
And if 3rd party batterymakers say it holds 3500 mah, it actually is only 2500.
Size-quality wise, the official is the best by far!
And if you are really scared of running out of batteries when you are on vacation or something, just get a 2nd battery? This way you can switch battery whenever you want. And you will always have a spare fully charged battery with you

alright cool, thanks lots for your help, been mostly an androidforums Guy, don't come here often

I have quite contrast opinion and experience on Anker battery on my SGS2. It mathematically holds some 16% more juice, but actually performs with 20-25% improvement. My friend who bought one for his Note (both orig and Anker are 2500mAh) says Anker holds up 15% longer (orig would drain every day between 7 and 8 pm, and Anker holds for another hour and a half, approx). It fits your original back cover, and I think it is worth trying.

Oh that sounds good, but don't companies like Anker, Chichitec and mugen "overadvertise" their battery capacities? A 1900mAh would be maybe a 1500mAh and a 1800mAh would be a 1400mAh?
Oh and did you compare your Anker 1900mAh to a new stock battery or one that's maybe 6 months old?

get the 2000 mah battery from samsung, its great, doesnt make the phone any thicker but it makes enough of a difference mate!

Anker is not overadvertisig its batteries like some Chinese factories. When I first tested Anker, my stock battery was some 3 months old. You should know that Anker batteries (as well as stock ones) need some 5 complete charges to start to act fully with their capacity, so do the test not the same moment when you buy the battery, but after 5-6 charges. I am using Anker battery now 99% of the time, and keep my stock one at home, full, just in case I need the phone full urgently. Every time I keep stock battery in phone I can see how it's depleated faster, so Anker is still better than stock one, some 8 months after using it heavily.
My stock battery is always on 15-20% at the end of the working day (from 8am to 22h-midnight), empty by midnight on weekends. Anker can withstand one day + night + morning shift on working days, and full day on the weekend, with some juice left.
Oh, and I use battery circle with % on it, so I can pretty accurately monitor
how fast is my battery draining while on internet, watching video, playing games (you don't see the % during the game, but you see it before and after), calling etc.

ho guys I found on a forum here on my country/county this announcement: http://forum.anunturi-galati.ro/index.php?/topic/335260-acumulator-baterie-samsung-galaxy-sii-i9100/
and i can't tell anything from the case and the info isn't to detailed... what do you guys think?

@gigeaky: a battery like this is fake... trust me!

Se vede ca-i chinezarie cea din link. Daca nu ma insel, pe cea mai ieftina baterie OEM de 2000 mAh am vazut-o la Orange Shop, 17 euro costa.
Cheers.

I last saw one that made the s2 just 1mm thicker I will post it when I find it again

i think the best extended battery you could get without any noticeable/annoying bulges, is the legit 2000mAh from Samsung.. it does not cost that much considering that it is not some hoax and it also comes with their custom back cover for the extended batter.. I don't trust Chinese products entirely
