There is so much hokem and nonsense out there it's not even funny.And actually I can use some words of wisdom here before I actually go and buy the phone. Apparently, different people have different opinions, some say the Li-ion batteries have the 'memory effect', some say they don't.
And I am really panicky about the battery, people using Galaxy S3 would understand.
So, the point is, what is the best way to:
1. First charge your battery as you unbox the phone?
The scenario here is you bought the phone, it is (suppose) at 50% battery level, so do you put it on charge right away or wait till it drains to say 15 or maybe 10% and then charge or let it get down to zero. Also, how long should be the first charge. I know manufacturers say the first charge should be around 8-10 hours (so that means you leave your phone plugged in even when it is fully charged) and does the first charge needs to be done with the phone switched off or it doesn't matter?
2. Maximize the battery life for standard usage?
I have read in some forums that you need to drain out your battery maybe once a month for a longer life but some people have different opinions.
3. And yes I have heard that keeping your phone plugged in when its fully charged has no negative effect on the battery (as the current to the battery is cut off), but is it advisable?
And last but not the least, is there any app (or rather any built in feature) which allows you to keep a track of the 'battery cycles'. I can understand that if there is no such built in feature, then installing such an app before your first charge will make sense. (something which I have heard iPhones have, I know my macbook has such a feature where you can check the battery cycles).
There's no pixie dust involved, just simple electrochemistry.
Here are your battery facts:
1. Most everything still alive in the way of battery advice is directed at technologies that have not been manufactured in years.
2. The lithium-ion batteries today are really a lithium/polymer. So -
* They have no memory.
* They do NOT benefit from being run down to zero or force-charged to 100% or any other schemes involving percentage-this or percentage-that.
3. It's still the same old story: metals + chemicals = current flow
* The metal in the battery consists of VERY tiny tubing.
* The real issue is HEAT - during use or charging, warm is ok, but very hot is not - because it leads to the metal tubes deforming. Once that happens, your battery life is degraded and will only degrade further - more heat=more metal deformation, less heat=less metal deformation.
4. Unless there's a defective charging safety circuit (and sadly, that has hit Samsung in the past), there is zero risk and zero gain from leaving your phone on the charger after it is full.
* Once it hits 100%, it cuts off the charger.
* Your phone will show 100% but will run off of the battery until around 96%, then the charger will turn back on.
* This leads to the myth: "Oh noes, I took my phone off at 100% and it lost 4% in 5 minutes! I must sprinkle pixie dust on my charging cycle and do funny resets to save my battery." Which - is not ever true.
* Your battery will never trickle charge - trickle charging would cause the battery to ignite.
5. Your calibration table will reset on every power cycle.
* Don't worry about it.
6. Two 50% charges = 1 charge cycle, a hundred 1% charges = 1 charge cycle
Avoid high heat, use your new phone in good health and don't sweat the battery.
