what stores besides apple can replace my iPhone battery?

Depending on where about's you are located. Any phone repair shops can help you with the replacement of battery.

You will need to check first that if will not affect your phones warranty though. Best of by asking Apple if going to a third-party repair shop will affect your warranty before getting i repaired. :-)

You can locate Apple Authorized Repair centers here https://locate.apple.com/. If a company or store is not found there, then they are not an Apple Authorized Service center.

If anyone but Apple or an Apple Authorized Service provder does the repair, you risk forfeiting all future warranty or out of warranty support from Apple. Apple and their authorized providers also warranty their parts and work for a minimum of 90 days. They are also the only places with access to new Apple OEM parts as Apple does not distribute those to anyone else.

Hi

If you don't have a Apple store nearby go to Support.apple.com They will send you a post paid box to return iPhone for battery check /replacement

Mine took 4 days use SIMCARD in other phone if you have one.
