This repo provides some information on the battery issue of Creative Sound Blaster E5.
- The unit can be used as a desktop DAC (always plugged in)
- Power management issues causing the battery is always in charging state as long as the MicroUSB is connected
- The unit gets very hot on normal operation
- The battery is directly touching the PCB and there are a lot of sharp pieces on the PCB
So nearly every E5 would get a swollen battery every 1-2 years of daily use, but Creative only provides a limited warranty.
Do your unit have this problem too? You can find out by the following methods:
- Is The front side of your unit (the one with NFC logo) curved? Place it on a flat surface and see if it fits.
- Is the metal bar (with SoundBlaster logo on it) not firmly attached to the plastic plate under it?
Check here for a new firmware release which might solve some of the power management problems.
See FAKE_BATTERY.md.

The recovery mode allows a unit with its battery completely drained to charge without bootloop. It also provides some kind of DFU thing.
To enter the recovery mode:
- Shut it down
- Unplug the MicroUSB cable
- Press and hold the SBX button
- Plug in the MicroUSB cable
- Release the SBX button if you see the middle one of the battery status LEDs start blinking.
