Replacing of battery

[Berts]

Hi ma'am/sir! Is replacing battery on a 3 year old samsung phone can improve the cooling efficiency of my device? 

Plus..

Should I purchase original samsung battery and have it installed on a nearby technician to save my money cuz it's just replacing battery?

Or

Should I surrender it to samsung service center and how much do they usually charge for SAMSUNG S21 ULTRA battery replacement?

I think weak = bad battery status. Need mo na palitan battery ng unit mo. Tingin ko mas okay talaga sa service center, pero ayun kelangan mo lang maghintay kasi minsan wala silang available battery i- order pa daw.

If its under warranty you can surrender it to samsunh service center but its not under warranty as what ive heard they cost a lot kaya sa nearby technician ka nlang po mura at meron sila options pero dapat sa legit phone technician. Tong samsung j7 pro maaus parin parang bago kahit 2024 na pinaayos ko sa legit na phone technician

Hello, do you know a legit store selling high quality samsung battery?

[SagaOtaku]

Its not legit store but legit phone technician. Kayo po mag iidentiy pag legit sila. Echeck nila yung phone pag mahal ang cost nila at di nila ma specify ng maayos kung bakit ganun ang price dun ka sa legit phone technician po

[Berts]

yes po I already had a legit technician, sabe nya kase maghanap ako sa online ng battery at sya ang magkakabit, kaso di ko alam mag legit check ng battery

[SagaOtaku]

No sir mali ang ganyan na process. Ang phone technician po dapat ang maghanap at nakaka alam niyan. Trabaho yan ng phone technician na sila dapat maghanap ng original battery at sila lang yung nakakaalam. Customer ka po hindi mo dapat ginagawa yan. Kung legit na phone technician yan alam nila kung saan kukuha battery suplier. Pinapadali mo lang trabaho ng phone technician at same price pa din ng pagpapagawa.

Okay po, Thank you!
