compared to B130, B340 is terribly bad..
when my H7 was in B130, it could last about 17 hours per day (i woke up at 6+am with battery about 95%, then charge at 11 / 12 pm everyday) with considerably heavy usage (scroll social media, web surfing, watch some anime and most importantly play more than 20 rounds of crash royale).
now i dare not go out without powerbank....
Maybe you would want to consider to change to B330

last time I do not have any issue with B330
Download HereYou could also double check your Protected App that labeled as Power-intensive, and consider not to protect it (except for Whatsapp)
Or, you could also root your phone and change to another rom.
Or, you could also roll back to B130
Roll Back LinkOnce you done the roll back, you may need to do a fresh installation for B130.
