WHY YOUR PHONE OVER HEATS AND DRAINS BATTERY VERY FAST

WHY YOUR PHONE OVER HEATS AND DRAINS BATTERY VERY FAST:
Faulty capacitors and resistors are the main reason for this problem.. as all electronic experts have to agree ,that capacitors do BLOCK direct current as they allow alternating current to pass,meaning that capacitors do smoothen the output from a power supply. thus when capacitors are faulty high levels of direct current will flow via the PCD thus leading to over heating! again,we know that capacitors store current ,when current flows to the metal plate via the dielectric forming an electromagnetic field where -ve and +ve electrons are absorbed and stored at the two metallic plates to be released later thus if capacitors get faulty alot of current will directly distributed and thus draining the battery fast! resistor limit flowage of current in high levels and reduce voltage to a desired level,e.g if a battery has 4 volts and a chip need 2 volts,2 resistors of equal resistance placed in a series will be needed to half the voltage to prevent heating.
Why and how do capacitors and resistors get faulty?
Its absurd that here in africa we almost get fake phones from shops,phone brands originating from china have taken over the whole of africa.Techno,airtel are soon getting up to 93% of the total number of phones held here in africa.Am not saying that most phones made in china are fake but i say "phones from china shipped to africa are all fake in one way or the other"
.1- These fake phones bought at cheap price are always made of cheap materials and involve cheap technology in their manufucture meaning that at and in any cost will always face alot of technical problems.capacitors and resistors in these phones are of poor quality and cannot hold or relay electric currents for long time that's why a chinese phone that was good at reserving battery may get worse as it get to one year in use.Weak circuit boards on which the capacitors and resistors are not firmly fixed such that when it falls down they usually get peeled off or loosely held on it.If one is not used to phones its very hard to detect such faults.Again,these phones have poorly designed circuit patterns that may lead to shortcircuits on the PCB.All these are responsible for over heating and battery drain.
2.Climate conditions and poor maintenance of phones! In africa people use phones for lighting where they put phones in the mouth and you know th torch of a phone is on top and usually its the charging system area that's directly exposed or put inside the mouth.As one exhales,its carbondioxide which foms a milk cloud and gets on the PCB and the resistors.when carbon dioxide mixes with saliva,moisture and other air components, they form weak carbonic acid that erodes the capacitors and the resistors. If you take a look inside your phone charging system or on resistors if you open it.you see bluish or greenish substances,those are oxides of the corroded metal from which the resistors are made.These corruded material bridge circuitry patterns or bridge resistor that are close and lead to short circuiting you literary call burning.You must put in mind that the resistors and capacitor that first does the regulations of current flow are near the charging system.Again,most phones when hit by rainfall andas you know that rain water is weak carbonic acid and highl corrusive as explained above, is also another cause of faulty capacitors and resistors.
3.Poor charging mentality and poor chargers: Phones have a limited time over which they must spend on charge.when its new,you owe to charge it for atleat 16 hours to make the circuit board used to electric current.How many do that here in africa.Some people have to leave phones to charger from evening up to morning.its even not allowed not to recieve call when charging or one should put the phone off when charging.The activities on phone use current and if we use it when its on charger it can lead to short circuit.many of us simply use chargers because they look to fit in the charging ports of our phones.we should know that different chargers have different power input and different phones hace different power the can take in through their charging systems and PCB.if you use a charger of high power in put on a phone of low power receipt, then you end up burning parts of the circuit board.....

  1. I am a Single full time dad on disability getting no help from their moms. It a struggle every day. My boys are 15 and 9 been doing this by myself for 8 years now it’s completely drained all my savings everything . These guys are the present day ROBIN HOOD. Im back on my feet again and my kids can have a better life all thanks to the blank card i acquired from skylink technology. Now i can withdraw up too 3000 per day Contact them as well on Mail: skylinktechnes@yahoo.com   or   whatsspp/telegram: +1(213)785-1553

FARDC and Wazalendo claim that many M23 have been neutralized and several villages liberated .

This Saturday 21/12/24 the village of KANYAMBI, a major stronghold of the M23_RDF in the Lubero territory was retaken by the Congolese army ...
