Your T665c was better than mine. Set at 100% for my old T665c I was getting 1:45 hours max. 2:15 if I set the backlight at 50%. So far my new TH-55 has gone 4:30 hours of set-up, PIM, and games and dropped from 4.20v to 4.09v. Not using Power Save Mode and the screen is at 100%. If only my T3 could do that .
FIA WRC: Fear not for your old T665C, in January, I sent my T665C for battery replacement (IMO, I do not think they replaced the battery). My T665 with old battery averaged 1:10 hours with 100%. Post-return I got 2:10 hours with 100%.
Anyway, I guess this is the official TH55 battery result thread. Since my TH55 got 4:30 hours, this meets the Sony battery life spec in the manual.
9 days when PIMs, such as Date Book, are operated for 30 minutes per day with backlight on*.
* The brightness level of the backlight is a the highest when the backlight is on.
Translation: 9 days * 30 min/day = 270 min = 4.5 hrs.
If you send or post your BatteryTime results on TH55 with backlight set to 100%, I am willing to collect, plot and post results using Excel.
This would allow users to compare their brand new TH55 to verify they are starting out with a TH55 unit with a healthy battery. If not, then they have time to return for a better unit (I think).
This is not precise, but with enough samples we can get a good average number to expect from new units.
