Its useless post lik this that keep this forum going
While i do have some news. Battery life is all dependent on radio, i have tried several with 1.02.25.28 Raphael being the best so far. That was until 1.08.25.20M1 Raphael was released on the 8th and since then battery life has increased quite a bit, approximately 4 to 5 dys of very light usage.

This all depends on location though. Im in VA so others may experience terrible battery life while others experience amazing life. It all depends unfortunately.
