Mine is at 3 bars here, but I do not recall where it was at when I put 531 on it. Keep an eye on the Russian forum to see if anyone else reports a similar issue, since it is possible that with all these changes the power management has developed a bug.
FWIW, Buggins has confirmed one bug with 531 that may even be relevant. He has found that if you pick through a lot of font files that CoolReader will read the fonts all into memory and then no longer release the memory. That eventually causes an out of memory condition and a system crash. The reason that I think that it may be relevant is that if the system crashes the processor and other electronics are going to be left in a running state instead of a sleep state and the battery will be depleted in just a few hours.
Normally a watchdog timer would reset the system and restart it, but it is not uncommon to keep that feature disabled in development versions of firmware.
