After I installed the indicator shows that my battery could last for 3 days and never goes below 60% then suddenly it shut down. I was looking to forum and searched about Z10 STL 100-1 battery problem and found the answer. I need to re-calibrate my Z10 using this methode:
1. use your phone until the battery completely empty
2. remove your battery, sim card and memory card for 30 minutes
3. charge your phone without battery, sim and memory card
4. wait until your led turn red and blackberry appears to your screen
5. put your sim, memory and your battery back to your phone
6. charge your phone until 100%
Now my Z10 can last for 10 hours on medium usage (emails, browsing and chatting).
