I had my iPhone 6s battery replaced by Apple in November last year (i.e. 5,5 months ago). Today the phone crashed and peak power was disabled again. Admittedly it was relatively cold outside (about 8°C) and I used the phone for navigation. Battery health is given as 98%.

Nevertheless, I am rather annoyed that an almost new battery dies on me and I wonder if I should complain. Is the replaced battery covered by any kind of warranty and does it extent to peak power capability?

  • 8C is 46.4F, so I'm not sure temperature is a factor. -8C is 17.6F, which is below freezing, but not low enough, IMHO, to cause such a problem so quickly. – IconDaemon May 6 at 12:11
  • @IconDaemon Before I had the battery replaced, I knew that my battery would reliably die if temperatures were around 0°C / 32°F and battery charge below 90%. So I basically always carryied a battery pack with me in winter. – n1000 May 6 at 13:36
  • The best way to find out is to go by the Apple store you had the work done at and explain the issue. – Steve Chambers May 6 at 15:15
