 ## To do - HARDWARE:
 * [ ] Add the MAX30102 Heart Rate Monitor to the current design.
-* [ ] Fix the issue with the DW01A chip, should be as easy as to replace the 100nf C12 cap with a lower value, let's say 80nf.

 * [X] Implement watch settings persistency using the integrated flash memory

 ### **To sort out :**
-* DW01A chip not driving the double N mosfet as expected :-(
-* Round lipo battery not having the capacity advertised, will have to change it :-(
+* DW01A chip not driving the double N mosfet as expected (when plugging a battery, the watch doesn't start without beeing plugged into the charger at least once).  
+Thought it might be a capacitor value issue, replaced C12 with a 82nf and 68nf caps, but it did not solve the problem :(.  
+**TLDR : after installing the battery, the watch might need to be plugged to it's charger at least once to start up**
+* The new battery should have a size of **26.8x26.8 mm** maximum : 602626 (400 mAh) would be a good choice.
 
 ## Next steps :
 * Finish to design and print the casing.
-* Find an other battery 450 mAh or bigger would be great.
 * Add BLE.
 * Write and release a usable firmware for every day use.
