Condition your phone battery??

[Billcoke]

Bro,

 

Is it necessary to condition your battery for better performance?

 

Read in a forum that once a month, allow the battery to drain below 20%, charge it up fully to 100% and leave it for 2 hours. But then read in another forum that discharging a Li-ion battery is harmful for the battery.

Once in a while (maybe a month) discharge your phone until it off itself, then charge fully to calibrate the battery.

 

Other than that, start charging when your batt reach around 20%.

Read about it on an article in Yahoo! except the 'leave it for 2 hrs' thingy......

i understand that discharging it regularly is for nickel cadmium batteries, due to 'memory effect'

Myth. No need for lithium battery.

 

The only thing need to reset is the battery strength sensor logic

It gets confused after multiple partial charge and discharge, and may report the wrong battery percentage strength.

calibration of the battery is needless as the component which is used to read off and subsequently return the value to Android for display purposes is the battery fuel gauge I/C chip. Any issues with battery capacity i.e. your battery is actually at 75% capacity and it is reflected as say 30% capacity is purely due to the battery fuel gauge chip. Some phones are designed having the I/C chip on the phone and others have it on the battery itself.

 

The Galaxy S2 i9100 is particularly prone to having a misread of the battery capacity due to the sensitive nature of the I/C. However, unless you swap batteries of slightly different capacities frequently, you will hardly encounter it.

Yup. Lithium Ion and Nickel Metal Hydride batteries do not suffer from this limitation.

i suggest let the battery totally discharge before re-charge

but then skali cant reach u

Totally discharge a lithium battery will kill it. But of course the internal battery circuit will prevent it from happening.

If you play lithium RC planes or cars, you will face such issues.

Or someone who plays with lithium LED flashlight also knows the con of draining a lithium battery cell below 2.7V is a no no.

My Hybrid's batteries also have this calibration design.

When battery gauge display empty, there is actually 50% more reserve charge in the battery pack.

That is my understanding too, but saw a few website recommendation to drain the battery every now and then like this website here, so a little confuse here.
