Battery Maximum Capacity!

Good time of the day! Im bothering you, i wanna ask about warranty of iphone! Last year I bought two iphones from Dubai, but i live in Uzbekistan! One of the iphone is black and another one is white! Black is still 99% of maximimum capacity, but mine(white) white is problem! I use 7 months, and now my phone battery maximum capacity is 92%. The phone is in perfect condition, no scratches and like new. I love my phone by Apple. A maximum of 3-4 percent is written on the Internet for a year, but mine sharply for a month 5-6 percent and 7-8 percent decreased in 7 months. I want to ask about what, there is a guarantee on the phone and what do you offer me? I will wait your message! Thanks

Normal battery health deterioration is 1% per month (Approx 12% per year).


Protect & Prolong life of your iPhone's Battery:

  1. About the battery usage on your iPhone, iPad, and iPod touch ...
  2. Batteries - Maximising Performance - Apple (IN)
  3. iPhone Battery and Performance



Try some of these options too.

  1. Avoid Screen Mirroring
  2. Put on Low Power Mode
  3. Put Auto Lock On (1 min):- with low power mode it will be 30 Sec
  4. Put Auto Answer Off
  5. Disable Push notifications for apps you do not use often
  6. Keep your iPhone Face down to prevent notifications to light up screen
  7. Enable Auto Brightness:- Settings > General > Accessibility > Display Accommodations > Auto-Brightness [Enable]
  8. Manually lower brightness from Control Center
  9. If you Want to watch continuous Video. Stream it on TV or a Monitor
  10. Don't force close apps; Apps which are not on frontend screen are paused by the system to save energy. Apps require more energy to re-launch. Apps which are open in the background use large memory is a myth and quitting them is counterproductive
  11. Location services to be allowed only while using the app
  12. Set your iPhone to fetch email and calendar data from internet less frequently
  13. Turning off Background App Refresh 
  14. Charge before it drops below 20-30%
  15. Try connecting to trusted Wifi where ever available in stead of Cellular
  16. Enable Airplane mode in areas with bad cellular and wifi coverage. Your phone keeps trying for reconnection with the missing / weak network. This uses lot of energy
  17. Switch off Wifi & Bluetooth while in Roaming or Not in Range
  18. Enable "Wifi Assist" : Settings > Cellular or Settings > Mobile Data > Wi-Fi Assist [Enable]
  19. Periodically Check your Battery Health (Settings > Battery > Battery Health)

If you bought the phones in Dubai, UAE......the warranty on the phones is only good in UAE.


It is normal for Battery Health / Maximum Capacity to decline at an average of about 1% a month, so after 1 year or 12 months, the Capacity will be about 88-90%.


Expect to replace the battery at about two years or 24 months, when the Capacity drops below 80%.
