Original battery
- Slightly more out of pocket around 30 Usd ,
-Expect to get full 5000mah with 2 batteries ,
- Peace of mind
-does not make phone bulky + No issues with cases
- Technically never have to connect the phone to charger if u have a battery
charger( around 17 usd)
Cons - U have to carry the extra battery with you.
- have to switch around
Extended battery
-is for people who dont care around the extra bulk and weight it adds to phone
-Dont want to switch batteries.
In the past I used to buy extended batteries but realised that i dont make use of the extra power much.
Hence i got a 5000mah portable battery for use in emergency and dont have to worry about getting battery everytime i change a phone
