Just ordered one of these puppies: http://cgi.ebay.com/Yoobao-Samsung-..._Batteries&hash=item1e61362f01#ht_1002wt_1139
Thought I'd give it a short review Anyway, I recently got a cheap vibrant that has a semi-borked cellular radio. I decided to use it strictly as a music player (the Galaxy S's audio chip is among the best)
With the stock battery, ZenDroid 1.3.4 + Bali UV Kernel 1.8.6 + KA7 modem, i was losing about 0.7% per hour idling (all wireless radios disabled). Playing music, it drained closer to 3-4% per hour
I got the battery yesterday and did a full drain + full recharge to condition the battery. It has been on for 13 hours now, with music playing for 4 hours continuously and it is only down to 90%. HUGE improvement!! With additional drain/recharge cycles (seller said it takes around 3 to reach optimal performance), I'm sure it will be even better.
Physically, this battery isn't much heavier than the stock battery. Although the included battery hood sticks out a bit, it fits very comfortably in my hand. When I hold it, my index finger rests on the angled part of the door. For anyone that is worried about the extended battery making the phone alot bulkier, rest assured it doesn't change it too much
Nice I might have to look into one now
Vibrant
Rom: Project-V
Kernel: Bali 1.8.6UV or tigers blood 3.22 UV -75 all around.
depends on how i feel
I have been shopping around for an extended battery and this is half the price of the momax battery. But the momax battery has a stand and a glossy cover, so im still undecided.
So these results were from no wireless and no cellular connections? Were you still receiving background sync data?

Not better than stock
I bought this battery from amazon. Am running Project-v and Bali 1.87UV. Was hoping for 2x stock battery life and did a full charge, recalibration, and drained it twice. But this battery does not work better than the stock one. The label said it was a 3500Mah, but Amazon advertized it as 2800. That discrepancy alone tells me to suspect the contents. I honestly doubt there is much more in there than a 1400.
Save your money and get something else.
I looked at several of these extended life batteries and I bought the Momax. Though it is more expensive I have been really happy with it. I can now use my phone for everything (voice, audio, video and data) and not worry about conserving battery to get through the day.
I was down to 45% the other day after using it 18 hours without plugging in and I had it displaying the clock for 4 hours straight while also checking Tweetdeck and answering emails during that time. I had GPS on even though I wasn't using it. I played music for about an hour straight too. Before I couldn't have played the music without almost draining it to that level.
I am completely ok with the extra weight knowing I now can enjoy my phone for the first time. I use it all of the time now. Before I was scared to bring the screen up for too long on days that I could not be near a charger. I like the kickstand on the Momax too. I bought the white one and my only regret is that I think I would have liked the black better. But I may get another one and give the white cover to my wife.
What's the verdict on it so far, OP?
I'd love to hear the verdict as well. Always nice to get extra battery life, but only if its worth the excess bulk.
I almost buy it,btw it's worth ?

Just want to share some early impressions of Anker 2500mAh battery for the Note.
I brought this on Amazon UK for £10, which is half the cost of the cheapest stock battery I can find from trusted online shops, the Anker seems few grams heavier than the stock battery.
I have used the Anker in the Note for two weeks now and decided to do a control test against the 4 months old stock battery.
The Note was set to play 720P version of “The six sense” on desktop version of YouTube using Boat browser at full brightness, with the sound at 50% output to a pair of headphones.
The YouTube page was refreshed every 1:30 hrs to restart the movie, and battery usage recorded after the 5% low battery warning popped up.
As you can see the Anker lasted 1 hr longer than the stock battery in the test. It would have been better if I had a newly conditioned stock battery to compare against the Anker. Still it shows the Anker advertised 2500mAh capacity is not too far off.
I’m going to continuing to use the Anker as my main battery and the stock as backup. I also had an Anker battery in my HTC Sensation for 3 months and was very pleased with the battery life, so I think it should stand up pretty well for long term daily use.
So if you don’t want to spend £20 on a stock battery, the Anker is a very good alternative. It is few £ more expensive than some generic batteries on eBay, but Anker has good reputation with their products, just check out the long thread in HTC Sensation accessories section.
Thanks for the compare. 4 hours screen time for stock battery is kind of disappointing.
I actually own one and it fairs well as a spare for prolonged usages.
I owned two spares for my Galaxy S2, also. So in a nutshell, quality and performance of the Anker brand has been consistently excellent.
For $12, it's worth the purchase. :thumbup:

To be fair, the test was designed to stress the battery to the maximum under controlled condition.
The Note was playing a 720p Flash video with full screen brightness. The movie also has very little black background, so the OLED’s power efficiency is minimised.
I also had the phone’s cell radio enable and CPU scaling set to “on demand” so the battery drains even quicker.
Under those conditions, 4 hrs of usage for a 4 months old phone battery is not too bad, a new stock battery would probably last around the same or more than the Anker did.
I've no problem using the Note all day long with the stock battery with Juice Defender to auto manage my data connection.
Agree, you were over-stressing the battery, but Engagdet got over 9 hours looping a video at 50% brightness (still overkill IMHO).
Also, in my experience, Juice Defender has always given me less battery life when enabled. I got about 30 mins more display time and 2 hours of overall time with Juice Defender off vs. on.

I'm confident that they were not looping a flash video, but a locally hosted video file. The OPs test.stresses the device much more as flash video consumes a lot of battery power to play, especially as he was streaming the video, and the screen consumes a large amount of power at full brightness.
For what it's worth, I bought one of these on this thread's recommendation, and have not been disappointed.
I purchased one of these for my S2, it was dirt cheap. Absolutely brilliant battery and it seems Anker have done it again, highly recommended and I may well purchase one of these for my Note soon.
Thanks for the battery recommendation!
What charger would you all recommend to go with this battery?
It has been a month now since using the Anker as daily battery, so I decided to run the same test again. As you can see, there is no difference compared to the test I did earlier, so it seems to be holding the charge. I'll do the same test again after 2 months to see what the difference is.

There is no way the Note battery can last 9 hrs, I got a new ipad on the weekend and was using the stop watch on the Note to time how long a full charge take. After 6 hrs and 30 mins, the Note battery was around 18%, the Note screen was at minimum brightness most of the time.
So I call BS to Engagdet test on the Note, even though their battery tests are accurate most of the time.
anyone know where to buy?

how about Nomax?
anyone hv any comment
i saw in ebay its look good but im not sure.
ok so i tested both batteries with a video!
(video = bf3 gameplay 1080p .wmv) looping over and over with mx player
each battery at 100%
stock is i believe 1850 mah
hyperion is 3500 mah
stock lasted 1 hour and 55 minutes at 10%
hyperion at 10% left beat stock by 45 minutes more
doesnt seem great increase in life but its something....any thoughts?
ohh yea i had to leave phone in my Frig because that phone was getting smoking hot
Hm.. I expected it to last longer than that. How long have you had the extended battery?
woah! practically double the size, certainly not double the life.. That's kind of disappointing
Sent from my LG-P930 using XDA

If battery is double the size the we should expect double the usage. 55 stock and 55 + 45 for Hyperion.
Sounds OK to me

@stemalo,
You missed that it was an hour and 55 for stock. So 115 minutes for stock and 160 minutes for Hyperion. Not so great.
I'm certainly getting close to double the battery life with my hyperion battery.
Perhaps you just got a dud? Also, cold temperatures are not kind to batteries, so that may have skewed results too.

battery ive had for about two weeks now...hmm i guess the frig didnt help my results
....well hyperion is like pretty much one hour extra...i guess its something
Some things to keep in mind...
1. New rechargeable batteries (of any chemistry) usually require anywhere from a few to a few dozen charging cycles before reaching peak performance.
2. There's no regulation on how a manufacturer goes about claiming the capacity of a battery, I have no doubt that Hyperion's rating of 3,500mAH probably has a real-life rating more in the neighborhood of 2,700mAH...Especially at such a discounted price.
3. Testing while looping a movie seems like a good indicator. I'd only suggest also putting the phone into airplane mode (to remove the radio from the equation), use an App Manager to make sure nothing else is running and lock the CPU to a specific frequency (if you have SetCPU) during testing.
Even so, 160min vs 115min is about a 40% increase over stock...So 1850mAH increased by 40% is right about 2600mAH, which is right around the range of my #2 statement above.
IMHO, with this 3rd party lesser-known name and at well less than the cost of what the OEM battery costs at -supposedly- half the capacity?...Yeah, I'm setting my own expectations on the low side when I receive mine that I ordered yesterday.

I just got a Hyperion 3500mAh battery for the Motorola photon.
The performance and charge time indicate that it is in fact a 2200mAh battery.
I was disappointed by the deceptive advertising, labeling, and bait and switch.
For the price not bad for a 2200mAh, but I hate the deception so I am going to shout it loud and far across the web, so people know what they are getting in not in fact a 3500mAh battery, but is a 2200mAh battery.
That is all
Wanting more battery life and having reading a few positive reviews about the Gold 3500, I got one from Amazon (UK). The numbers 3500 vs 2500 mah indicate I should get around 40% extra battery life compared to stock but having played with RC cars and helicopters running LiPo packs I know that pack ratings aren't everything.
Actual battery capacity depends on the discharge rate, the more juice you pull the less the effective battery capacity you get with a lot of energy wasted in heat due to internal battery resistance. Fact of life with batteries of all chemistry.
My original battery is about 6 months old now, charged daily from anywhere between 0-50% remaining. In day to day use the Gold does seem to last longer based on my 6 months experience with the original battery but how much better is it?
I charged the batteries in my phone and turned the phone off once it hit 100% but kept the charger on as it seemed to charge for a bit longer.
Using my RC battery charger, I used the discharge function setting the low voltage cut off to 3V (standard for lithium batteries) and set the discharge rate at a constant 300 mah. Using a constant discharge rate may not be realistic but it does allow for a fair comparison, keep in mind that our phones power usage jumps up and down depending on use.
Results
-----------
6 month old stock battery rated at 2500 mah = 2364 mah (which is what I would expect from a battery with 180 cycles on it)
Brand new Gold 3500 rated at 3500 mah = 2524 mah (a bit disappointing but at least as good as a new stock battery)
Now the discharge rate can make a big difference to effective battery capacity, it might be that the 3500 mah rating on the Gold batteries was determined using a very low discharge rate or they discharged it to below 3V.....or its just a gold wrapper over a stock battery
Interesting to note that the stock Sammy battery is pretty true to its rated capacity, so the perceived increase in battery capacity I experienced with the Gold battery is probably just the difference between a 6 month old battery and a new one.
Oh well, at least I have a spare battery now and didn't pay a fortune for the Gold. The Gold does seem to last a bit longer than the 6 month old stock on so I am happy enough with it.
Notes:
Gold battery had been in use for 2 weeks to run it in
Only one discharge cycle was performed
Could be that I have a dud battery, you results may differ
In real day to day use the discharge properties of the Gold may result in a higher 'effective' capacity
Solar flares are the source of all coding errors
Fairies do live at the end of your garden :cyclops:
It's a shame i've read this post only two days after buying me one of those. Anyway, even if it won't last longer, i'd still have a spare battery right? So everything is not lost
nope, its a shame they rate it 3500mah if this is the case for all.
Mignon, maybe your can get a replacement from thrm and test again. Especially if you have a dud.
Do notice I notoce a significant increase in battery life after charging it past 100%. Probably placebo, I dont know.
Don't think I have a dud, in my experience lion batteries either work or don't. It's not a crap battery, it's just as good as stock but doesn't match the advertised 3500 mah rating.
And it's shiny gold so things aren't that bad

Well that sucks.....haha...i order a gold a week ago.....it should be here soon.....
I got 3500mah gold battery. I review it.
My rom is ultimate rom v5.1, and my stock battery was 11 months old.
Screen on time was always less than 4 hours.
Yesterday I got the gold battery, and I used it up to 1% without first charge, then I charged it 12 hours to initilize the battery.
So unpluged the charge, and tested it as the same usage. I always downclocked to 1000MHz, wifi on, no use 3g data, brightness is zero, bluetooth and gps is off. I downloaded 15 files and apps today, listened to music, did multi windows function, and almost used web browsing.
Now my battery is just 1%. Screen on time is over 5 and half hours. Obviously the battery was improved.
If official JB are released, the battery will be improved more.
But this is not made in Japan. This is made in China because Japanese is so strange on package.
Some of Chinese battery are so dangerous and may be fake, but this gold battery is good one.

I dropped my stock and it works perfectly till 55% then it dies. Gonna throw it away soon. So some of the cells could be damaged. Its not either they work or dont m8.
@Mingnon thanks for your effortful tests.
@eeynjae, what are all apps spreading around those icons in your notification bar ?
I am pretty sure most mobile 3.7v phone batteries are single cell, only the mugen styled battery extender jobs that require a different back cover run two cells in parallel.
Remaining capacity is usually just a function of cell voltage so it's strange that it should just tank at 55%. Battery protection circuits generally prevent discharge past 3.0 volts so not sure what it's going on there.
Either way it sounds like you need a new battery, wouldn't risk recharging a damaged cell...

yeah its strange. Stuff started to happen at 50, whrn restarting bat percentage dropped to 10-15%. Without restartingbit would go down normally in beginning. Now after using it some time and dropping it its 55%.
Its definitely it either works or doesnt.
Anyway I dont think it's single cell.
i have the same battery bought it a few months back i'am very satisfied....
it's not a 40% extra time even framework it designed to work with less voltage since after using it below 15% i notice always fake meter value, when you keep your phone asleep for half an hour you will notice an increase in percentage. not accurate but runs fine, its a spare and a great replacement i dont care if it's slightly powerful than stock at least its the same size for 4 extra hours.. i never needed to change case nor a cover of anything its great
Sorry for my off-topic question, but i see in this topic there are advised people recently i bought a noname car charger for my Note, (specs: output 5.5V DC, 800mAh) - is this charger good for the Note or it would damage it?

Thanks for your time and efforts - your results are similar to my amateurish measurements performed twice and reported on the other 3500 battery thread. Having no device to test the actual capacity, I just used the continuous video playback in plane mode with minimal backlight. The time to full discharge was almost identical in both cases.

It won't damage your phone, but if you are going to use it as a gps while charging, it will probably keep dranig the battery, 800mah is not enough to charge it while screen is on and gps is running

I've read mixed reviews on these bargain batteries. We'll see I guess.
There were three 3500s left when I posted this thread.. now there's 2. Who else bought one?
I plan on running stress tests from full charge. (screen on 100%, gps on, wifi, data, fm radio, and google music streaming)
The best battery I used was 2 evo4g 1900 mah batteries for 7$ on eBay. The battery lasted 2 days with decent use but unfortunately I could not get it to charge with the phone on any rom... even though the polarities looked the same as our batteries.. if only..

Yea the $4 one came in yesterday and after 36 hours I can tell it's not as good as the original oem. It's not horrible and will serve as a decent backup.. but certainly not a DD battery.. no way.
I'm more curious to give the 3500 a spin. Hopefully that arrives today.
Can't wait to hear about the 3.5Ah!
I have a 2.2, I think. Probably could last me three days if I didn't surf and play so much.
Edit -
I should mention that I usually end the day with about 50% left.
Today I'm already at 14% at 6pm because I watched two hour-long videos and did all the other surfing stuff as well.
Curious what you use to test your batteries with.
I run Battery Monitor Widget Pro and always wipe stats for a new battery. Great app for tracking battery performance.

Sorry, I haven't been able to test much. The performance was so crappy the few times I did use it that it hasn't left my shelf ever since. I know I said I was going to do standardized tests but I've been super busy the past few weeks.
As for the anecdote- I charged the 3500 up to 100% and went out for a night on the city at about 2pm. It was dead by 11pm and I was pissed. However, I'm not willing to pass judgement on it yet because I was running PAC at the time which absolutely devoured whatever battery I used.
Now that I'm back on stable CM7 it's a bit different. I'll charge her up tonight and do some comparisons this weekend.
In my experience a battery needs to be exercised a few times before it "matures".

So I don't have any definitive results. Overall the 3500 does last longer but not by much. I ran it from 100 to 1 twice over the past week and made sure it received standard use and no charges. I have attached 2 screenshots of the drain plus one with the top culprits for drain. Like many 3rd party batteries it tends to take a nosedive once reaching ~18%. You have maybe 10 minutes left when it hits that mark.
My workplace has horrible signal so cell standby is probably much higher for me than it would be for most. For comparison, my OEM lasts about 14-18 hours without a charge.
Bottom line:
3500 mAh linked above- You can't go wrong for $9. It performs like a ~2500mAh. the case is good quality too.
1500mAh linked above - might come to the range with me next time for target practice. That thing is worthless and is maybe good for 4 hours of standard use. Streaming a 1 hour playlist from Google music used approximately 40% of the battery.
Good to hear.
It's sad that we can't trust the ratings on the batteries, but I am glad it worked as well as it did and that the cover was acceptable, too.
I've read a lot of battery reviews on Amazon and even then it's a tough decision to make. Like you said, for the $9 it's ok.
I'll never buy a $50 battery, but if I did I would certainly expect it to perform to the advertised spec. Sadly, the reviews on those batteries are as mixed as the reviews for the cheapies.

Some interesting information
Bought similar battery a few months ago. On standart battery I has only 10-15% left at evening (music, instant messaging and serfing drains battery wery well), with this enhanced battery my phone lasts 2-3 days. I attached the photo to compare it with default battery.
The main disadvantage of it, suddenly, was the incredibly low signal level (only 1 bar on WCDMA in wooden house, 2-3 bars on GSM), problem was in antenna that is located at the down of back cover. As you can see, two contacts was joined. Just split them, and signal should improve. It helped me, but not too noticeably. So, I have to put copper wire on the back cover and even to prolong it beyond. It looks very ugly, but now signal level is even better than on stock battery (always full signal level on the street even in 3G mode). Low signal level results in higher battery drain and heat.
I don't know why HTC decided to save money on antennas in our phone. Because stock battery cover GSM-antenna is worse than any Nokia (it's much smaller, but in antennas, size matter, a lot). Wi-Fi antenna is bad too.
Also, battery indicator in our phone is not works as it should, I think. 0% is actually not zero level. Real Lithium-Ion battery zero level is 3.2-3.3V (sometimes even smaller, but it's not recommended to to discharge it beyond this level, it may damage battery), but HTC controller tells 0% at 3.5-3.6V and Android forcibly powers off the phone. When I used De-Sensed V firmware, where Android power off function on zero battery level not worked (may be, it was disabled in services.jar, there is the way to do this thing), I could run up to one hour in ICQ on 0% and even some hours in idle mode, before the battery controller blocked battery discharge to protect it (voltage was around 3.2V). It's disappointing that I can't make an urgently call while I actually have the power level enough to do this.
Thank you! Very nice to read your solution for the antenna!

I have good luck with my antenna, so I doubt I will have to do any fixing.

AckerMAN_ can you give more details about your antenna fix?
I see in the photo that the cover has two plastic fingers that are painted with copper colored paint.
My cover has metal fingers attached to it for the connection. They are like springs.
Can you attach a photo of your antenna wire, please?
This phone is famous for poor signal and many others would be interested in a way to improve reception.

There is a photo of back cover with attached wire. Also, I attached the screenshot of current reception level. I hope it will be useful.
Also, I'm thing about patching services.jar, I'll try it when have enough time.
