STEPS: 1. Download and install xRecovery from here. 需要xRecovery....這個應該不用解釋吧~~ 2. Charge your phone to 100% 把你的手機充電到滿 3. Turn off the phone and boot into recovery 關機然後到xrecovery 4. In recovery, go to Advanced options --> Wipe Battery Stats --> Yes 這句還要解釋嗎?? 5. Take the battery off 把電池拿掉 6. Insert the charger chord 把充電器電源接上 7. Put the battery back and wait for the phone to boot 把電池放回去然後等手機開機 8. Once the phone boots up, you will notice that the battery percentage is around 88% instead of 100% 這時候應該會看到只有88%讓他繼續充到100% 9. Charge the phone back to 100% 10. Repeat 4-5 times, seems to be the sweet spot 重複以上動作四次到五次~~應該就會到100%囉~~ 11. Enjoy your hopefully better battery life and report!
