i got a little lag after update to os7.1. already reinstall twice & wipe my OS. still the same.
lag when scrolling thru the app at home screen & when slide pictures.  not really an issue but i can feel the difference compare to previous 7.0 OS.

no fix so far, but it get better after few battery pull although not as smooth compared to default os7.0.
i think i can live with it. my android lag is worse than this

Doesn't look normal to me. My phone left the charger at 7am (100%) and now at 2:30pm (after 7.5 hours), I still have 75% of juice in my original JM1 battery, on 3G+2G mode. 3 push mail accounts active (gmail), a bit of foursquare, twitter and facebook activity, about 5-10 mins of calls and 3-5 SMS messages plus some light whatsapp and BBM.

Note : I am running the leaked OS7.1 on my 9790 with battery saving mode enabled.

hmm... very good.. if u used ori batt it should need charge... where u bought the sunglobal battery?

my battery last 16 hours++ (2g + 3g). very heavy usage on bbm/ym/wa, 10 minutes call, 20 minutes browsing.
6am off charger (100%) --> 12am(2%) before radio shut off
[attachmentid=2702858]
dont know why it show so much usage on home screen.

IMO, best bb i've ever had and use. buttery smooth UI.
keypad is soft & comfortable. autofocus camera.
battery can last 1 day with very heavy usage.

Well, my usage pattern has not changed, other than the fact that I ran os7.1 on my 9810 and am also running os7.1 on my 9790.

Battery life for me on the 9790 has been the best among the three models. I don't have to worry at all about running out of juice from 7am to 11pm. In fact my 9790 still has 40% batt left now. Don't even need to consider the sun global 1850mah batt

hi i'm new here and new to this forum too.

i just wanna ask if anyone know where to get extended battery high capacity? to be specific, higher than 1850mAh which currently using this. and it is SunGlobal. i bought this battery on June 2011. and now it seem to drain after 4 to 5 hours only, after (approximately) 9month of usage.

i'm using the obsolete Curve 8520, hahaha

and one more thing, is worth it to use Yoobao power bank?

anyone mind to share?

please add me to the owner list tq.
