Root SBC dilemma

[MusicJunkie]

I'm running Mason's .14 SBC kernel and I'm not seeing a difference between non-SBC and SBC kernels. I got a drop off when I unplugged my phone. I was under the impression that it wouldn't drop off since it's SBC. Can anyone explain or help me with this? Thanks.

Did you unplug your phone when it read 100%? If so, you're supposed to keep it on the charger until you no longer get -mA's (which can take an additional 30 min. - 1 hour on the charger). You can use an app such as Battery Monitor Widget to monitor the mA's.

I recommend reading the original SBC Dev's XDA thread so you can get a better understanding of what the SBC kernel does.

Thank you because I didn't see anywhere that I had to do all of that. Just charge and it's supposed to just work.

Also, I didn't unplug it as soon as it reached 100. I was sleep for about an hour and a half when it was on 85% then woke up and unplugged it then went back to sleep

No problem.

Well you do just charge it and it works...

SBC charging is really most useful for people who charge the phone overnight. The threshold for 100% that the phone recognizes isnt the true 100% of the battery. Therefore, you have to let it keep going after that untill the battery stops taking current.

Consider wiping battery stats (battery calibration) as well after giving it a full night to charge

That's what I did, sorta. I woke up and unplugged it and then ended up passing out again.

Naps don't count as overnight charging.

Let it charge overnight and in the morning run the battery calibration app before taking it off the charger and you should be good to go after that

Okay

Edit: I might not have been that accurate on my time in my previous post but I'll just let it die and completely charge it again and see if I get the drop off again.

Update:

Around 3 the phone charged to 100%. I left it charging when I eventually went to sleep. I woke up around 10, unplugged the phone, and didn't get the drop off. *wipes forehead* All is well now!

Just an FYI on how ALL chargers work on the Evo. SBC or not, the circuit has a timed cycle when it samples the battery for current loss. If that sample is every 10 second or every 10 minutes will make a difference of what happens when you unplug the charger. Li-ion/polymer batteries want to be charged slowly. Once the battery reaches a certain CURRENT point, the charging circuit shuts down. It might reach that current point when the VOLTAGE is only 4.0V ( as an example only ). As the battery cools, the resistance changes and so does the voltage. When the circuit samples the battery, it might say "oh! It can take a little more now" and push current into the battery. It heats, changes resistance and turns off the charging circuit.
Now... depending on WHEN you unplug your during that sample cycle... You could see a drop on your "meter" because it is looking at the battery at a different time period than when fully charged.
Letting the phone sit without use is the best way to charge the battery. That is one of the reasons that I strongly suggest that ANY user take one night, turn OFF their phone and let it charge overnight. This will allow the battery to get to a good, stable state.
I hope this helps a little.

See ya'

Man. What can I say? You're an expert at this stuff and I appreciate your input.
