build 10586.107 on Lumia 1520 (Philippine variant), update straight from 8.1
1. Update was smooth, and it took about 40 mins to complete the process.
2. However, the messaging app is not working. Messages would not load, cant send or receive text.
3. People hub, likewise, is not loading the contacts
4. Tried to find a fix- updated all apps, then receive another round of update (a patch probably), then performed a soft reset.
5. The problem was not resolved, so I have no other choice but to do a hard reset.
6. Hard reset took only 15 mins, but restoration from back-up point took a while.
7. Messaging app is now working fine, from the back-up I was able to restore Lumia Camera, Lumia Camera Beta, LCS, and LCS beta. I also have the revamped Windows Camera.
8. I lost my BPI App
9. SMS messages was not completely restored (yet as of this writing)
10. Contacts not yet completely restored as of this writing
11. Contacts sync to Facebook not completing
12. Twitter contact sync took some time.
13. Edge browser is fast compare to Explorer
10. No crashes from the apps I used so far
11. Wifi will disconnect, w/ no apparent reason
12. The interface is better, than 8.1
13. Have not thoroughly tested the camera, but rich capture works, if you'll use any of the Lumia Camera.
14 Facebook beta is better in W10 than in 8.1.
15. There is serious heating issue
16. Stand-by discharging rate is 3-5%; when I begin to receive updates via notification and started browsing, discharge rate jumps to 15-22%.
17. Battery died in 8 hours (used to take 1 1/2 day for heavy use and 2-3 days for moderate use)
18. Using a powerbank is pointless, because the discharging rate (15%) is faster than the charging rate of 6% (2.1A output).
19. Charging thru an electrical outlet also takes some time. On the same charger under 8.1 charging rate of 20-25%/ hour. Under W10, you have to enable airport mode to achieve a 16% per hour charging rate.
Anyway, this is only the first day, will observe performance first and decide if I will revert to 8.1 after a week of use.
