Battery Drain After Full Charge

---

Scenario: Overnight Charging

ROM: Stock
- Battery charges to 100% 4.2V, Charging stops, battery starts draining, to 4.1V then charging starts again to top up the charge. this happens repeatedly overnight. I believe this is ideal.

ROM: Custom ICS or JB
- Battery charges to 100% 4.2V. Charging stops but battery just continously drain. No top up charging occurs.

ROM: Stock Again
- Battery charges like before. 100% then top up charging


I think this is a ROM or Kernel issue, but im probably wrong. Is there a fix to get Top Up charging for custom roms and kernels?

Install better battery stats app from xda and try to investigate the reason behind battery drain.

im not concerned about the fact that its draining, im concerned that its not topping up the charge.

ok, so i am now using project x 4.1 with redux .7 kernel. the charge is topping up. im happy now . i wish a JB rom will have a nice working kernel soon
