Upgrade to b521 2 weeks ago, battery life is much worst than previous, even charging also got problem, not sure is hardware or software problem

Previously fast charge half an hour can reach 50%, but now only 30% after half an hour

Battery drain faster, previous can last me until night before sleep, now just half day already drain from 100 to 20%

Looks very abnormal, any solution except back to emui 4.1?
Thanks

Don't think so, I've uninstall and reinstall fb and messenger after heard the news, still same, one think i found is the "android system" consumption level is the highest in my battery drain list, is much more higher than others apps or system, it's abnormal, but don't know what make it consumption so high and how to solve it...

Yes but when 😁

When B521 will get the stable version update ? Battery drain much faster than 4.0, and whatsapp notification keep delay, need to open the apps only can see the msg come in, already lock it in the task manager and also unpick it for "close the apps after screen off" in battery setting there, still didn't help, anyone with solution?

Thanks.

Just update, so far so good, a lot of minor bugs removed, monitoring the battery life now

Firmware finder show b585 updat, anyone receive from ota from b563?

Official ota not yet receive, ff download but authorization fails when install

Did anyone fact battery drain issue in b585? I update few days ago, I check battery usage it show "contactStorage" drain a lot of battery, someone face the same problem?

I just change my battery 2 weeks ago, just 1 issue, the phone charging sometime will disconnect especially during calls, what I can do is restart the phone only can charge properly, quite annoying, anyone face the same problem?
