Hey everyone,
I'm using the "Battery Calibration" app to calibrate my GS2 battery, and I have already charged it to 100% and wiped the "batterystats.bin" file, and completely discharged it.
Now I have a question about charging it back to 100% - I'm going to be charging it while the phone is turned off, so how long should I leave it on charge before I can be absolutely sure it's at 100%? Some posts suggest 24 hours, while others say overnight or even 8 hours or so is completely fine and enough for the battery to become fully charged. Also, I don't need to "bump charge" to properly calibrate it, correct? I just let it charge to 100% now, and then I can use it as normal, right?
Thanks in advance for your help!
8hours ish should take you upto 100%
And after its upto 100% its fine to use it as normal.

...yep...when you see on the display (by clicking home button) the battery icon showing inside 100% then you can unplug your phone and use it normally...battery have a limit of charge just to avoid corruption so when they are at 100% they automatically stop to receive more charge...that's why I think is useful to leave the phone in charge more than he need.

...sorry I haven't seen you already answer
Thanks for the responses guys!
Now, it has been about 3 hours since I put my phone for charging, turned off, at a completely discharged 0% battery (I even tried download mode before I put it for charging, to make sure it was completely discharged), and now the charge meter is showing 100%...
I'm pretty sure that 3 hours is a VERY short time to charge to 100%... I haven't taken it off the charger yet, so would you recommend waiting a few more hours (maybe 5 more hours?), or is it fine to just take it off the charger right now?
I'm worried a bit now, because 3 hours seems an extremely short amount of time to charge a battery that is 'supposed' to run for 18+ hours...
Well, I just read that 3 hours is about normal, so thank you for your help!

Firstly, there isn't such a thing as battery calibration with Lithium batteries. Since there is NO MEMORY EFFECT.
Lithium batteries are not Lead Acid batteries, it does not need 8hr to 16hr trickle charge.
Charging is controlled by BMS, there is no such thing as Charging past 100%. So when it is considered 100% by the BMS (Voltage), the BMS will stop charging it.
Lithium batteries gets damaged when there is less than 10% charge, so emptying it to 0% is not a good idea. You cannot really extend Lithium batteries lifespan since it only has a 2+1/2 yr lifespan, 2000 to 5000 deep charge cycles and around 2,000,000 micro charge cycles. It is better to charge anytime you want, as long as it does not go below 10% (Most electronic equipments will state 0% at that time).
Deep Charge Cycle, when close to 0% (10% charge left in battery) you can charge 2000 times back to 100% (depending on quality of battery)
Micro Charge Cycle, when roughly above 40%, you can charge 2,000,000 times back to 100%.
Soooo..... would you like to limit battery charging cycles to 2000 or prefer that you can charge it 2,000,000 times?
Guys, kindly help me, I'm not quite sure on how to properly take care of my Xperia P's battery. Should I discharge it to 1% and charge it to 100% all the time? or should I charge it often?
There is no problem in charging often but atleast you should let it drain it upto 50 to 60 percent

Its a myth - you don't have to drain your battery completely and then charge it again to the fullest for longevity
leap before you think

Thank you for the quick responses guys
Both of us, you and I have a lithium polymer battery. Some tips I follow for the life of my battery pack.
1. Do not let battery discharge to less than 10% too long.
2. Always charge your battery short of 100% ie 85-95%
3. Always turn off your phone and charge the battery to get an accurate reading of battery percentage.
Cheers....

Is my charging routine bad? Here is my daily recharging
I let it charge over night. By the time I get home its normally in the 60% or so. So its left on all night until about 7am.
Then about half way through my day I charge it again while I'm at on my office. By then the phone is around 70%. So I let it charge to 100% then move on with my day.
So about 2 times a day I charge my phone. Is this healthy for the battery or does it not matter? I'm trying to get the most out of my battery. I seem to burn about 3-4% per hour with it just sitting on desk. Thanks for any advice!
Well my battery die sooner charging it as often by chance?
thats about how i do it and have never had a problem
That's how I do it. I wait till it's dead or close then charge. It's probably better to do it like that than every night because if your like me it gets to about 30% at night.

No at the end of the night when I get home its around 60% or so most nights. I then let it charge to full over night. I then unplug it in the morning and charge it again at my desk around noon when its about 70%. There for it never really gets any lower than 50%. I must be honest I dont fully understand the best practices of battery charging. I care only because I can not just buy a new battery like I could if my S3 died. So I am making sure the way I charge my battery is not killing it.
letting it die and charging to 100% are worse than charging from say 10% to 95%. read this to get info on battery life and charging

the battery is charging very slowly
hi all is there any way to charge the battery faster, as it takes about 5 hours to charge from 0% to 100%

I use a battery charger with a spare battery. You can buy them on eBay for 8 or 9 U$D. This way you never have to wait until the phone is charged as you always have a charged battery. Moreover, I friend of mine had an issue with the miniUSB port long time ago as there seems to be a defect on the phone if you charge it using the charger that comes with the phone. It overheats the connector and finally the phone becomes unusable. At least that is what Samsung told my friend. Since then I have been using a spare battery with a wall charger.
Hope that helps!
Hey guys, this is a simple question.
Should I wait for my phone battery to completly die before recharging it or should I wait at like 5-10 percent to recharge it?
The battery's don't like going under 25% or over 80%. Wikipedia lithium battery...
Ha. Charge it whenever you want. It doesnt matter.
