charger overnight..SCREEN ATTACHED
By examining logs of the battery monitor widget, I see that the 'stock' battery charger seems prone to continued shallow discharge/charge cycles after reaching 100% if you leave phone on the charger for long periods such as charging overnight.
In am pretty sure this is bad for the battery.
One strategy would be to monitor the charging and remove phone from charger once it's at 100%. But that's not always practical.
Maybe turning the phone off when I put it on charger for the night would help?...I'm not sure.
Is there a better charger that won't abuse my battery if I leave it on charger overnight?

Ok. It doesn't do it every night, but it did it last night.on screen the top graph is voltage and bottom graph is current. Positive current is charging current. The distance from left to right is a little more than 8 hours. 1st hour-phone is not in use, everything constant. Next 1.5 hours phone in use, voltage decreasing, current negative. then put phone on charger in airplane mode with screen off. Next 1.5 hours it charges, voltage increases while showing positive constant current.next 1 hour the charging ramps down., charging current decreases. Then charging stops itself. Next hour no activity, current stays 0 and voltage roughly constant.then it starts charging again by itself with a small decreasing positive current for about an hour!!!!. Then turns off the charging and zero current for an hour. Then current jumps up positive for very brief period with shallow charge starting again just before I wake up, take it off the charger and turn on display...current turns negative right at the end.
You can't see that 2nd shallow charge very well because it's so short, but you can clearly see the first shallow charge in the middle......after it had stopped charging,for an hour it woke up and charged lightly for an hour.I want it to stay off once it stops charging.

Re: charger overnight..SCREEN ATTACHED
Here is my 2 cents. My PRIMARY use for the SII is for phone communication. I can usually receive 2-3 days of standby with a minimal (~60 min) of talk time. When the battery nears 25-20 %, it is time for an overnight charge. Even though the charge time is <3 hours, I turn OFF the phone at bed/charge time to let the electrons rest and to make available full charger power for the battery charge cycle. The battery full notification jingle usually gets me up to let out that last beer and to then turn on the phone and let a new boot-up begin the day. I go back to zzzzzzzzzz's and let the phone have another couple of hours to top off the charge. I figure it is better to boot while on the charger and let the battery do it's thing while running around un-plugged....
Just installed the Traffic Monitor and will keep a lookout for any rogue battery burner apps.
Got carried away with the topic. Should really be posted in the SII thread. Still had good results with my infuse using the same procedure...
