The cheap golden batteries are crap, they claim to hold more power and are usually from China, but they are weaker than stock batteries, there's only a few brands I trust, zerolemon, anker, etc, pay a bit more but know you're getting good quality, no good having an expensive smartphone n risking ruining it by buying n using a cheap battery...

Did you notice that the S4 mini original battery is labeled 3.8V while earlier batteries were labeled with 3.7V? You may know that Li based batteries are very sensitive to charging voltage and may overheat when the wrong voltage is applied. All the aftermarket batteries are 3.7V and their charge-stop is around 4.2V while the original is 3.8 with charge-stop at ~4.3V.
Not sure if and how the charge circuit deals with this situation, but it could lead to problems in this combination.

can try looking around ebay for those extended battery with 4800 or 6300mah. but have to use their special back cover though which means no protective case.

@junkyde

Is your kernel compatible with dual sim version (i9192)? I'm looking forward to swap the phone for this version, but I'd like to keep using extended battery, with your kernel of course :)

Since my original battery was gonna be weak, i've bought a "Polarcell Akku 2100mAH NFC edition i9195", from Amazon Store, € 15,99

Just charged, initialized and in use, i will post screenshot of first use.

I'm using s4 mini lte i9195, firmware kitkat 4.4.2 ucnf7 rooted, debloated, vodafone lte sim, always wifi/edge connected, mid daily use.

Hi! Don't forget to post the screenshot because my battery is weak too. I hope the Polarcell 2100mAH works better than the original one.

anxious...

6300 from dx.com, shortly: skip it...

Hello guys,

just to share with you, I've bought this one from dx.com SKU: 252144
advertised: 6300 (Actual 5500) mAh

Mesured it with RC models li-on charger, safe conditions 500mA charge/100mA discharge and acctual value is far from declared and around 2900mAh

Just skip it.

Regards,
rasterer

Junkyde I PM'd you. I am not that good with this rooting and kerneling but will the 6333MAH version you did be good for for a 5100mah phone?
It will work, better with stock kernel. But it will drain battery very fast when around 20% left, because yours is smaller than kernel says.

but I should still get some amount of usage as I would with letting it drain and then turning on again to 50+% battery ?

btw what's the best way to install the vkinger kernal junkyde posted? I managed to root my phone and I have cyanogenmod 11 on my phone but when I tried installing the vkinger mod I just got boot loop
maybe it's just best to stick with powering on phone to 50_% battery after it drains. I should still get a good 2 days usage right??

Not sure what you ask... What I meant was that 6333mAh specified in junkyde's kernel is a 100% of battery. That is what kernel says. If your battery is 5100mAh it is about 80% of 6333mAh. That's why the phone will "die" when it gets below 20%. If not faster... I don't believe you have a real 5100mAh capacity ;)

Simply flash it with CWM.

You can always stick to the stock kernel and reboot the phone when it gets close to 0% of course. But it's annoying in my opinion. Plus this custom kernel gives you more pros like BLN as example.

Does the kernel only work on CWM10.2?

Zerolemon battery :) they are good.
