Haddii aad leedahay iPhone, iPad ama iPod, waxaa laga yaabaa inaad dareentay wax yar oo aan caadi ahayn oo ku saabsan habka ay wax u dallacaan: dhaqso ilaa boqolkiiba cayiman ka dibna tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiib tartiibለዉለዉ ጋር11515155115 ugu soo dhoweysay ay ugu soo dhawaatay. Waxaan tan ogaaday dhowr toddobaad ka dib iyo maadaama aanan waxba ka aqoon hadda, koronto, volts, amps, chargers, iwm, maan hubin in tani ay tahay habka iPhone-ka ay ahayd inuu ku dallaco iyo in kale.

Ugu dambeyntii, waxaan sidoo kale ku tijaabiyay iPad-ka waxaanan ogaaday inuu sameeyay wax la mid ah. Waxay ku dallaci doontaa qiyaastii 70-80% si dhakhso leh ka dibna si weyn ayay hoos ugu dhici doontaa ka hor intaysan gaarin 100%. Dhab ahaantii, xisaabintayda, wakhtiga ay qaadatay in laga tago 1% ilaa 80% waxay ahayd qiyaastii isla wakhtiga ay qaadatay 80% ilaa 100%!

Maqaalkan, waxaan ku sharixi doonaa inta yar ee aan bartay oo aan fahmay ee ku saabsan ku dallaca alaabta Apple waxaana rajeynayaa inay ku siin doonto xoogaa faham ah waxa dhabta ah ee socda. Haddii aad tahay injineer ama qof wax badan ka yaqaan mawduucan, xor u noqo inaad fikradahaaga ku dhejiso faallooyinka!

Ilaha Korontada vs Chargers

Waxa ugu horreeya ee la fahmi karo waa farqiga u dhexeeya isha korantada iyo dabaysha. Waxay u badan tahay inaad sheegtay bayaanka hoose ugu yaraan hal mar noloshaada inaad leedahay qalab kasta oo Apple ah: "Aaway dabaylahaygu?" ^{( “Where’s my charger?” )}

Nasiib darro, hadalkani farsamo ahaan waa khalad. Fiilada iyo adabtarada aad gidaarka ku xidhayso runtii waa il koronto. Waxay hadda ka soo jiidataa gidaarkaada waxayna ku siinaysaa qadar go'an oo amps iyo watts ah iPhone kaaga, iPadka ama iPod. Dabaylaha ayaa dhab ahaantii^(charger) ku jira qalabka laftiisa. Taasi waa sababta aad u isticmaali karto dallaca iPhone si aad u dalacdo iPad ama iPad-ka si aad u dalacdo iPhone.

Dabeylaha gudaha iPhone ama iPad-ka ayaa maamula qulqulka hadda ku socda aaladda, ma aha adabtarada. Haddii aad waligaa hubisay, adabtarada iPhone waxa lagu qiimeeyay 5 watts iyo 1 amp. Adabtarka iPadka waxa lagu qiimeeyay 10 watts iyo 2.1amps.

Charger iPhone iyo iPad

Bateriga ku jira iPad-kaaga ama iPhone-kaaga waa baytari lithium-ion polymer ah oo dib lagu dallaci karo. Waa waxa ay Apple u isticmaasho dhammaan qalabkooda, oo ay ku jiraan kombuyuutarrada Mac . Apple waxay leedahay bog weyn oo sharxaya waxoogaa ku saabsan tignoolajiyada batteriga^{(their battery technology)} , laakiin qaybta ugu fiican waa jaantuskan ay bixiyaan:

Bal aan eegno shaxdan. dhidibka Y waxaanu ku leenahay Voltage Hadda (A/V). A waxaa loogu talagalay amps iyo V waxaa loogu talagalay volts. Lambarka koowaad waa amps kan labaadna waa volts. dhidibka X waxaanu ku haynaa marxaladaha dallacaadda: dallaca degdega ah iyo dallacaadda. Marxaladda 2aad waa waxa sharaxaya sababta qalabkaaga Apple uu hoos ugu dhaco oo ay qaadato wakhti dheeraad ah si aad u dalacdo markaad dhaafto 80%.

Sida aad arki karto, tirada amps waxay ahaanaysaa 1 (iPhone, 2.1 ee iPadka) labada saacadood ee ugu horreeya ka dibna hoos u dhacaya labada saacadood ee soo socda ilaa eber marka qalabka si buuxda loo dallaco. Waxay u badan tahay inaad sidoo kale dareentay in mararka qaarkood marka aad ka saarto iPhone ama iPad-kaaga charmerka, waxay noqon kartaa meel kasta 96% ilaa 100%. Tani waa sababta oo ah dallacaadda qulqulka. Markay gaadho 100% way damaysaa. Haddii batarigu bilaabo inuu hoos u dhaco, wuxuu dib ugu soo laaban doonaa ilaa 96% oo wuxuu bilaabi doonaa dallacaadda mar kale si tartiib ah.

Maxaynu Ugu Bahanahay Dallacaadda Trickle?

Markaa tani waxay xambaarsan tahay su'aasha: waa maxay sababta aan ugu baahanahay lacag-la'aan? Waa maxay sababta aan si degdeg ah loogu dalacin ilaa 100% oo lagu dhammeeyo? Hagaag^(Well) , sida muuqata waxay la xiriirtaa kimistariga ka dambeeya baytariyada lithium ion, taas oo aanan wax fikrad ah ka haysan. Isku soo wada duuboo, baytariyada lithium ion waxay si xun uga falceliyaan in lagu dallaco si xad dhaaf ah sidaa darteed marnaba ma rabto inay taasi dhacdo.

Dallacaadda Trickle^(Trickle) waxay xallisaa dhibaatadan iyadoo hoos u dhigaysa hadda ee qaybta dambe ee dallacaadda oo gebi ahaanba joojisa marka batteriga si buuxda u dallaco. Taasi waa sababta aysan sidoo kale waxyeello u lahayn inaad ka tagto qalabkaaga oo ku xiran isha korontada xitaa ka dib marka uu si buuxda u dallaco.

Gebagebadii, dabaysha ayaa ku dhex jirta qalabkaaga, waxa aad gidaarka ku xidhaysana waa adabtarada korontada, ee maaha dabaysha! Dhammaan tignoolajiyadaani waxay u jiraan inay asal ahaan ku ilaashadaan nolosha batterigaaga wareegyo badan oo lacag bixin ah. Haddii aad wax su'aalo ah qabtid, noogu soo sheeg faallooyinka! Ku raaxayso!

OTT Explains – Why Your iPhone Charges Fast First and Then Slows Down

If you own an iРhone, iPаd or iPod, you may have notiсed something a little odd about thе way it charges: fast up to a certaіn percentage and then slower and slower as it gеts closer tо 100%. I noticed this a few weeks back and since I know practically nothing аbout current, electricity, volts, ampѕ, chargers, etc, I wаsn’t surе if this was the way my iPhone was supposed tо charge or not.

Eventually, I tested it out on the iPad too and realized that it did the same thing. It would charge to around 70-80% pretty fast and then would slow down significantly before getting to 100%. Actually, from my calculations, the time it took to go from 1% to 80% was about the same time it took to go from 80% to 100%!

In this article, I’ll explain the little I learned and understood about charging Apple products and hopefully will give you a bit of an understanding of what exactly is going. If you are an engineer or someone who knows a lot about this topic, feel free to post your thoughts in the comments!

Power Sources vs Chargers

The first thing to understand is the difference between a power source and a charger. You probably have said the statement below at least once in your life in you own any Apple device: “Where’s my charger?” 

Unfortunately, this statement is technically inaccurate. The cable and adapter that you plug into the wall is actually just a power source. It draws current from your wall and delivers a set amount of amps and watts to your iPhone, iPad or iPod. The charger is actually in the device itself. That is why you can use an iPhone charger to charge an iPad or an iPad charger to charge an iPhone.

The charger inside the iPhone or iPad controls the flow of current into the device, not the adapter. If you ever have checked, the iPhone adapter is rated at 5 watts and 1 amp. The iPad adapter is rated at 10 watts and 2.1 amps.

The iPhone and iPad Charger

The battery inside your iPad or iPhone is a rechargeable lithium-ion polymer battery. It’s what Apple uses for all their devices, including Mac computers. Apple has a great page that explains a bit about their battery technology, but the best part is this chart they provide:

Let’s take a look at this chart. On the Y axis we have Current Voltage (A/V). A is for amps and V is for volts. The first number is amps and the second one is volts. On the X axis we have the stages of charging: fast charge and trickle charge. Stage 2 is what explains why your Apple device slows down and takes more time to charge when you get past 80%.

As you can see, the number of amps remains at 1 (for the iPhone, 2.1 for the iPad) for the first two hours and then drops off over the next two hours all the way down to zero when the device is fully charged. You have probably also noticed that sometimes when you disconnect your iPhone or iPad from the charger, it could be anywhere from 96% to 100%. This is because of the trickle charging. When it reaches 100%, it shuts off. If the battery starts to drop, it will kick back in around 96% and start charging again slowly.

Why Do We Need Trickle Charging?

So this bears the question: why the heck do we need trickle charging? Why not just fast charge all the way to 100% and be done with it? Well, apparently it has to do with the chemistry behind lithium ion batteries, which I have no idea about. In a nutshell, lithium ion batteries react very badly to being over-charged and therefore you never want that to happen.

Trickle charging solves this problem by reducing the current at the latter part of the charging and completely stopping it once the battery is fully charged. That is why it is also not harmful to leave your device connected to a power source even after it has fully charged.

In conclusion, the charger is inside your device and the thing you plug into the wall is the power adapter, not the charger! All this technology is there to basically preserve your battery life over many charge cycles. If you have any questions, let us know in the comments! Enjoy!
