Isoloko igxekwa ukuba i-Apple yongeza kuphela i-1 Gb ye-RAM kwizixhobo zayo xa ukhuphiswano sele lunezintathu. Zombini i-iOS kunye ne-Android ziinkqubo zokusebenza ezimbini ezahlukeneyo ngokupheleleyo ezineemfuno ezingenako ukuthelekiswa. Ngelixa kuyinyani ukuba imemori ye-RAM eninzi isixhobo sinayo, kokukhona siya kusebenza ngokutyibilikayo, iimodeli ze-iPhone ngaphambi kwezi zikhoyo zisebenza ngokutyibilikayo, ukuba asiyithatheli ngqalelo iSpotlight lag nge-iOS 9, kodwa kubonakala ngathi Uhlaziyo olukhulu lokuqala lwe-iOS 9, i-9.1, luyilungisile le ngxaki.
Abasebenzisi abasele besonwabela iimodeli ezintsha ze-iPhone kunye ne-2 GB ye-RAM ibango lokuba ukusebenza kunye ne-fluidity kuphuculwe kakhulu xa kuthelekiswa neemodeli zangaphambili. Ndiyathandabuza kakhulu ukuba umahluko uyabonakala xa uvula okanye uvala usetyenziso, kungakhathaliseki ukuba bathini abasebenzisi. Apho kubonakala khona indlela iSafari esebenza ngayo, xa uhamba phakathi kweethebhu esizivulileyo.
ISafari ibisoloko inomsebenzi obuhlungu xa sineethebhu ezininzi ezivulekileyo kwaye sifuna ukuhamba phakathi kwazo, nokuba yeyiphi i-iPhone okanye i-iPad esiyisebenzisayo. Ukungabikho kwememori kuphawuleka ngakumbi xa uvula isikhangeli kwaye uye kwithebhu ukuyivula kwakhona, kuthatha imizuzwana embalwa ukulayisha kwakhona umxholo.
Kwividiyo, sinokubona indlela uBenjamin athelekisa ngayo ukusebenza kweSafari kwi-iPhone 6 Plus kunye ne-1 GB ye-RAM kunye ne-iPhone 6s entsha, ukulayisha amaphepha alishumi kunye nokuhamba phakathi kweethebhu ezahlukeneyo ukujonga ukuba i-GB yememori isinika ngokukhawuleza kangakanani. I-RAM eyongezelelweyo ekhoyo kwiimodeli ezintsha, njenge-iPad Air 2, i-iPad yokuqala yokubetha imarike kunye ne-2 GB ye-RAM kunyaka odlulileyo.
