Hey guys, Please help. I was having a eu rom when I bought my phone, then i feel like some bugs for some apps. So I flash the rom with developer rom 5.0.12 version. But then it doesn't have LTE signal on the OS. After a month I ask my brother to flash it with stable rom 7.0.12, then the baseband version is unkown and it goes for hours and it keeps lagging. So then a few hours later I try to root my phone with TWRP then flash my rom. I do some flashing like twice or 3 times before this version. First I tried to flash with official rom but it said zip signature failed. Then I try to flash it with the newest rom from this thread, and it works. My phone works normally at first. But then few hours later, I charge my phone all night like from 1AM till 6AM, but the battery won't fully charged, it's only charged till 46%. Isn't it weird? Because I usually charge my phone only for 3 hours or more. I just realized that I was flashing rom when the battery power was below 10%. But then when the last time I tried to flash it the battery power was aroun 30%. Now I tried to charge my phone, it getting sucks. First it's only 23% then charged for 25% for half hour. Then I turn it of and charge it, it charged till 31%. Then I charged again it stuck on 25-26%. What can I do? Is the battery is broken or the ROM? Thanks.
