Well i dnt actually know why but I tink dats for older batteries. Modern Lion batteries dont require full charge at first use. Infact when i bought my phone newly the instruction mannual sugested i drain the battery first before charging to 100%. Same thing i read when i bought a new laptop battery few months back. Was asked to drain to 8% befor charging to 100% for first time. So find the instruction manual that came along with ur phone and read the part about the battery. Am sure u wil get answers 1 Like |

For SINGLE Cell Li-ion devices: There is no reason that charging a Li-ion battery up the first time before playing with your new device, would in any way extend the life of the device or the battery. The simple fact is properly stored lithium-ion batteries are charged to about 50%, and lose some of that charge (depending) while sitting around in the package, or being shipped. So properly treated the battery will have less than 50% charge when you get it. Why are they recommending or even insisting on getting you to charge? Because when you first get a device , you spend a long time configuring it and testing it. When you first test the device it gives you a "first impression" of the device. The battery WILL run out. Running out sucks :-) Because almost every Li-ion device sold has a protection circuit to keep the battery from dropping too low in voltage, there is no reason to enforce this policy or worry about it other than, It is going to run out, and you will be unhappy. If when you get your device, the battery voltage is so low that your device will not operate, you should definitely charge the battery, before leaving it in said device. The battery should not have come to you in that condition, and would be a suspect battery at that point. The low voltage protection could have saved it mostly still anyway. How bad the battery would be at that point could vary from totally usable still, to completely unusable. This all changes slightly, and gets more confusing with higher voltage Li-ion batteries. SERIES: With laptop batteries it can be more important to charge before use, because a proper charge circuit could balance. This all gets very complicated and muddled. A "proper" circuit for series Li-ion would not ever allow any cell in the series to get so low in voltage that it it could damage a battery. Fact is , there are improper circuits out there, that do not monitor Every cell in the battery pack. But often those same poorly done battery packs and charge systems will not have balance either. So there is one type of series pack style (no individual battery cut-off) that it would be far better to charge it first before using it. Under very specific situations, with this one type of semi-proper system, it could damage cells permanently to a small or large degree, even on the first "way too low" discharge of a single cell. Other non reasons: To calibrate the Battery, While many devices have a specific Ma usage metering capability in the chip, there is no reason that charging it then or later would change that. Again even if the battery uses this kind of "info lithium" or "smart" capability to determine battery fill, there is still (usually) protection that would keep the battery from being damaged. Some of it might come from older battery types like Ni-cd and Ni-mhy where a full charge is way more helpful, And can balance out a series set of batteries prior to discharge. This keeps the battery set from reverse charge. Because Li-ion (every one) is supposed to have protection, and also should be balanced on charge, it does not balance the same way Ni-?? chemistry can or do. 2 Likes |

Urban legend I kill the battery parapara just testing the apps and speakers on my new phone, then I charge it with Nigerian phcn up to 50% so the battery will adjust its sense to Nigerian power supply Charge am full, you dey pamper the battery, charge am reach 20% and try use am for 15 hours |

Re: Why Are New Cellphones Battery Require Full Charge Before Use? by lightblazingnow(m): 7:29am On Nov 17, 2016 |
The instructions are, charge battery to full capacity and not endlessly charge. So monitor your phone cell to know when it is fully charged. Because it came half charge from the manufacturer N.B the phone must be switched off against any distractions to the unused cell, to fully charge |

If this thread was created in year 2001 , then i agree.. the days of 3310 has gone.. Technology has advanced now.. we are talking about quick charge 3.0. wireless charging and so on.. in 30 minutes of charge your phone is 83% already.. |

It doesn't change anything whether you charge it for 500 hours before using it or not... That is the lie being told by omo Igbo just to deceive you from testing the fake battery you bought from them |

They get charged fully from the factory, but who
knows how long those batteries have sat on a shelf,
then put in a box and sat on a shelf before that phone
was sent to you. Charge it fully every night; Lithium
ion chemistry prefers partial discharge to deep
discharge, so it's best to avoid taking the battery all
the way down to zero. Since lithium-ion chemistry
does not have a "memory", you do not harm the
battery pack with a partial discharge. If the voltage of
a lithium-ion cell drops below a certain level, it's
ruined". don't let it drop to zero on a regular basis,
but it is good to zero out every now and then; stay
away from heat.
"Batteries may last longer if not stored fully
discharged. As the battery self-discharges over time,
its voltage gradually reduces. When depleted below the
low-voltage threshold of the protection circuit (2.4 to
2.9 V/cell, depending on chemistry) it will be disabled
and cannot be further discharged further until
recharged.[clarification needed] It is recommended to
store batteries at 40% charge level" |
