i bought 4950mAh battery for my galaxy s4 and the battery percent display get to 100 before the battery fully reloaded how to could i know my real percent is there any app or something like that?
How do you know the battery is not fully charged?
Indeed, the battery is likely fully charged, as new batteries do come from the manufacturer partially charged to prevent the battery failing from not having any energy in it during transit.

Hi I have G2 Korean version with removable 2600mah battery which is lower than the int'l version with 3000mah. I've use it for 2 months now until last week when it's the first time I forget to unplug it before I sleep so it was charged overnight. Then at noon time, the phone suddenly shut down with very thin lines. So I quickly charge it but there is a blinking red light. After an hour of plugging and out, thankfully, it charged properly but now I'm only getting 12 hours battery on light usage. I've heared that the non-removable 3000mah gets 19 hours battery, is this true? What's the normal battery life of the 2600mah? Should I get 16 hours (2600mahx19hr/3000mah)?
Did something gone wrong? Any recommendations? I still have warranty. I tried calibrating my battery by draining in and charging it fully while off , calibrating by software (Battery HD) and charging after 30 mins of usage of a fully charge battery (jump starting). Please note that same thing happened on the other battery which also charged overnight on the external charger pack.
Thanks.

Any link for rooting the korean version and any free app for freezing apps?
Thanks.

Hi all,
Today I have purchased Galaxy S5 SM-G900F. The shop sales rep mentioned that, when I'm charging this phone, I have to charge it 6 hours (online charge), even if it's fully charged. They mentioned that that method will improve the battery life. Is it true?
I read somewhere that modern battery doesn't have memory effect. So should I plug my SGS5 G900F 6 hours?

Use it and discharge it under 5% then plug it in to charge it to 100%, that's all. No need for 6 hours charge on S5.

No you shouldn't. Nevertheless most people will tell you to do so anyway. The advice is intended to assure that your battery reaches 100% charge and gives you a good first impression of battery life. It's also stressful to your battery.
Ideally you'd charge to 85%, which is probably 0 - 2 hours charging depending on how much charge your battery has out of the box. Then aim for shallow discharge cycles thereafter. Running to depletion and high temperatures are the worst things that you can do to a lithium ion battery. And charging to 100% is stressful too.
Of course if you want maximum run time and will not be near an charging source, then you will probably charge to 100% anyway. A tradeoff between utility and overall battery life.
There are lots of existing threads on this subject, replete with useful information for anyone that does a search e.g. this or this.

Is there a need for battery calibration ? If say some percentage ranges the battery drops reasonably and at certain percentages the battery just dives. If so how do I do that?
No need to calibrate your battery (ITS A LITHIUM-ION BATTERY), use it as you normally would. Enjoy it till the Note 5 comes out.
But if you want to extend the lifespan in your battery (don't confuse with everyday everyday life), a complete discharge once in a while is still recommended.

I've just recent purchased a official Samsung spare battery for my N910C. I charged it fully after I received it in the mall. But when I used it for the first time today it said that it had only a 80% charge despite the fact that I charged it fully when I received it in the mall. I did some research online and found a couple of methods on how I could calibrate the battery without having to root my device. But I'm not sure which method is the best.
The 1st is:
To drain the battery fully.
Then plug it in and charge it again.
Then drain fully again and charged it fully.
The 2nd is to:
Drain the battery fully.
Turn it on and off.
Then plug it in to charge.
Once the LED or display says it's fully charged, unplug it.
Power my device back on, which will stated that the battery not fully charged.
Plug it back into the charger and let it fully charge.
Then reboot it to check if it's full charged.
If it's not repeat the previous couple of steps again
Does anybody know which of these is the best method for calibrating the battery of a Note 4?
So after two years of poor battery life, I was instructed to reset my Galaxy S4's fuel gage chip, and am now getting solid results that actually come quite close to my Galaxy S7's results (but without cellular data or the sheer amount of apps on it).
However, my battery still dips very quickly in active usage, before "recovering" some of that when in standby. Of course, unless the Galaxy S4 includes a self-charging feature that is no longer included on newer Samsung phones, this is the result of an uncalibrated battery. Any way to do that without rooting?
Some pictures just to show you what I mean.
The S4 has a fuel gauge chip? That's one I haven't heard before.
There is no way to calibrate the battery. Battery calibration apps in the Play Store only delete the battery stats file, and that gets deleted by Android when the battery is fully charged. The battery does have a microprocessor for voltage regulation during charging, but you can't touch that and it's most likely not the source of your battery suddenly "charging" itself.
The solution to your battery issue is simple: get a new battery.
calibration usually means running from fully charged down to nothing ie when the phone switches itself off. from there you charge it up until full without letting it over-charge (this is bad for your battery) and not using it while it's charging.
charge levels are estimated to the best of my understanding, so your level can go up after heavy use.
Having a battery with physical damage or a faulty charge circuit is a bad thing. Physical damage to the battery is rather obvious, but a fault in the charging circuit can cause an overcharge condition as the battery reports the wrong numbers to the device. You're 100% correct that overcharging the battery is a bad thing, as an overcharged battery may explode. It's unlikely to happen simply from expending a charge cycle.
As to expending that charge cycle, trying to calibrate a battery by running the battery down then charging it up does nothing for the battery except waste a charge cycle. Draining to zero and recharging to 100% made sense when combating the memory effect in NiCd batteries, but is useless with Li-Ion. A Li-Ion battery doesn't keep a record of its levels, and Android deletes the batterystats.bin file when the battery is fully charged and the device is disconnected from AC power.

Apparently so. There's a reset command (*#0228#), and it will instantly drop your battery to zero, at which point you can charge it to 100. It works on all Samsung devices that I tried so far.

If you use it while it still has some charge left, where does the remaining charge stored in the battery go?

It's still there, but the system no longer reads it and will likely get drained as part of the next charge.
