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? (i read somewhere that the original car charger's output is 5V... this difference of 0.5V has any importance?) Thanks.

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

Why is that?
After i've received mine, i've never ran out of battery during my day. Definitively improved the usage of my phone.
Hello all,
Just a quick question, I ordered a new battery the other day (2450 mAh) and it only charges to 80% before saying it is full. I'm sure that even though I'm on stock kernel I should be able to run a larger battery, so I'm assuming the battery is faulty.
Could anybody give me clarification on the biggest battery size you can run on stock kernel?

Do a battery calibration, google it.
I lot of the 'unbranded' batteries with optimistic power capacities have no regulations around what they state the 'real' usable mAh life of the battery is.
I'd be very surprised if the battery gives you longer usage than your original 1700mAh battery.
I'm guessing it'll probably be considerably less.
There is no limit to battery capacity within the limits of what you can physically fit into the recess provided for the BA900 battery.
Mugen Power can only get a 1900mAh battery in that size... so that's something to consider when you think about a 2450mAh battery.
Hello!
My S4 Mini's (LTE) battery isn't really good and I would like to buy a bigger replacement.
I've found this https://m.aliexpress.com/item/32670956124.html but it doesn't really convincing, but it's very cheap.
Yes I know about NFC cheap, but I don't use NFC.
What do you think? Could I buy it? Or it doesn't worth that money?
Your money, your rules.
I would say yes
Warning!
I heard some bad things about Aliexpress. I wouldnt buy something there.
I've bought one. Inside there are 2 stacked cells that are slightly smaller than the original battery. The actual capacity would be around 1.8x the original. The other problem is that you need to make a change in the battery management driver source code and recompile the kernel to reflect the increased battery size to have an accurate battery gauge. (search the xda forums for the thread) Other wise the phone will report 0% and shutdown when in fact the battery is half full. You can switch it on again and it will report around 50% but again it will shut down when the battery is still has a quarter charge in it.
I have the recompiled kernel for 12.1-20151117 for the serranoltexx as a .zip you can patch in recovery if you would like it.

I bought lots of stuff at aliexpress. They always deliver.. Until now. lol.
I also bought some high capacity battery's for my old s2 plus.
Although the capacity they say will not be reached, it is still a good battery in most cases.
Check the reviews on the site, loads of people comment and if the battery is crap you'll know fast enough.
Hi,
just to share with you, I bought similar one from dx.com SKU: 252144
advertised: 6300 (Actual 5500) mAh
Mesured it with RC models li-on charger, twice...
safe conditions 500mA charge/100mA discharge and acctual capacity is far from declared and around 2900mAh
Just skip it.
Does anyone tried a different battery capacity? I found a 3000 mAh on ebay, did anyone tried it?
Do you think is harmful?
Thank you in advance
Is this battery built by HTC was is a third-party battery that is working with HTC?
It isn't a HTC battery, is a spare with more capacity, but I don't know if it's harmful or not, I didn't found anything in internet about it...
I don't think the battery capacity will harm the phone, maybe just the battery will hold longer or not, depends on it's quality.
The point is: does the actual stock battery has a fix number of cycles or whatever? The actual battery has 2850 mah capacity, the new one 3000...the difference of 150 mah will be recognized by the mobile? This is my concern..

The phone will charge and discharge the extra 150mAh but the correct capacity will not be reported by software.
Anyway 2850 vs 3000 is a little change, and if the battery quality is lower than HTC original battery maybe you'll not see any difference or maybe the battery will hold shorter.

From what i've seen on the Galaxy Gear S forums, somebody fitted a bigger battery inside and it worked just fine.
And his watch now lasts a few more days.
Anyway, for 150mAh more is simply not worth the risk.
Hi.
My name is Andre.
I have an xperia play that I've been using as a pocket emulator for years.
I have the NexPlay Rom installed, as well the recommended LuPuS CM9 Kernel and .58 Enhanced firmware.
Recently I bought one of these 4500 mAh battery and back cover from ebay.
The original charge it came with lasted a good while so I really believe this is not a fake battery.
But I can't get the phone to recognize the new battery capacity and charge it. The phone seems to only charge it up to the original 1500 mAh.
I've added the following line to build.prop (the line wasn't present) through the BuildProp Editor app:
ro.semc.batt.capacity=4500
But even after clearing the cache, davik cache and resetting the battery stats, I see no changes.
Can anyone help? I'd really appreciate it.
sorry i cant help, but a 4500mah battery sound nice, when i had the xplay i had a 2450 mah and worked fine, the only problem is it decayed its capacity very very quickly

Thanks anyway.
Since my original post I've done more reading, searching and testing.
Turns out there is nothing functionally wrong with the phone, other than it still thinking the battery is 1500 mah for battery duration calculations.
The charge percentage is correct, and the phone is charging the battery until it reaches a voltage of 4.2, which means it's full.
It's the battery itself that is only taking in about 2800 mah. The seller said he would send me another one.
