A battery charger, or recharger, is a device that stores energy in a battery by running an electric current through it. The charging protocol (how much voltage or current for how long, and what to do when charging is complete) depends on the size and type of the battery being charged. Some battery types have high tolerance for overcharging (i.e., continued charging after the battery has been fully charged) and can be recharged by connection to a constant voltage source or a constant current source, depending on battery type. Simple chargers of this type must be manually disconnected at the end of the charge cycle. Other battery types use a timer to cut off when charging should be complete. Other battery types cannot withstand over-charging, becoming damaged (reduced capacity, reduced lifetime), over heating or even exploding. The charger may have temperature or voltage sensing circuits and a microprocessor controller to safely adjust the charging current and voltage, determine the state of charge, and cut off at the end of charge.
Chargers may elevate the output voltage proportionally with current to compensate for impedance in the wires.A trickle charger provides a relatively small amount of current, only enough to counteract self-discharge of a battery that is idle for a long time. Some battery types cannot tolerate trickle charging; attempts to do so may result in damage. Lithium-ion batteries cannot handle indefinite trickle charging.
Slow battery chargers may take several hours to complete a charge. High-rate chargers may restore most capacity much faster, but high rate chargers can be more than some battery types can tolerate. Such batteries require active monitoring of the battery to protect it from overcharging. Electric vehicles ideally need high-rate chargers. For public access, installation of such chargers and the distribution support for them is an issue in the proposed adoption of electric cars.
Good day po Tanong lang po lalo na sa mga technician
Paano malalaman kung original battery ang ni replace ng technician sa smartphone?
nag pa battery replacement po kasi ako sa authorized xiaomi service center
Redmi note 9 po model ng device ko. Pinalitan ko siya ng battery due to bootloop, unfortunately if 20% na siya mas madali nang malowbat lalo na kung nag gi-games. I think 1 percent nababawas within 5-10 seconds. Na try ko na po siyang i-calibrate pero dati pa rin. Any alternative solution? Thanks!

Pros:
Good for gaming
QC 3.0
Enough Storage
Long Battery
Cons

No casing(you have to make your own)
Sa banggood ko binili 1 month bago dumating...
ano ba magandang phone under
15-20k na mabilis pang gaming
at maganda ang camera
pa suggest naman mga ka p.s tnx
paki explaine pros and cons sa dalawa po
May alternative way po ba para mabuksan and phone nakacharge po sya hanggang dun lng malaking battery :) salamat sasagot ung unit po myphone iceberg :)
Pahelp naman guys kung au problema nitong cellphone ko, kasi ang nangyayari dito ay namamatay bigla kahit nasa 50% or Nasa 60%+ pa siya, namamatay bigla.
Anu kaya ang sakit nito?
Battery ba problema? or grounded?
Salamat sa tutulong.
Hi ka PHC may tanong lang po ako
Halimbawa yung phone ko 100% tapos nag games lang po ako tapos 80% tapos biglang namatay paano po yan sana makatulong ano ang recommend nyo po ty
Kabili ko lang ng phone ko sa lazada, nung july 5 po naideliver. Pero last week lang lumabas yung charging issue ng phone.
Pag nichacharge ko, lumalabas charging. Pero hindi nadadagdagan yung battery percentage. Patulong naman po kung anong defect neto, or kung phone ba or charger ang may sira...
Mga ka PHC! good morning/evening po sa mga interesado sa mas matagal na battery life. TAMAD AKO MAG CHARGE. Marami siguro makaka relate o may mga nag titipid sa kuryente (tulad ko). Eto pong mga susunod na apps ay para pahabain battery life ng mga ROOTED PHONES. Kung alam nyo na tong mga to edi...
Sabi ng professor ko na Electrical Engineer, tatagal daw ang buhay ng baterya ng cellphone kapag inilagay sa freezer for 30 mins to 1 hour na nakabalot sa plastic. Totoo kaya yun? Your thoughts mga ka-PHC? :unsure:
