    I’ve been using the TS’s ROMS since the end of 2015 on my mi4c.
    So far, no matter what, I was able to get somewhere between 3h-3h45m SoT; once got 4h30m but it never happened again.
    My battery got worn lately (ie. phone was switching off at about 30%) – ordered a new one, replaced – it got better in terms no surprise at 30% level, but not much better battery life from charge to charge
    So, I thouhgt I’d flash latest MIUI ROM to delete all leftovers and so on and reflash CM13.1 to see how battery life changed. Imagine my surprise to discover that I got less than 2h SoT within 12 hours of use! I didn’t install anything new – just flashed MIUI, run it for couple of hours, hated it, reflashed latest CM13.1 by TS and restored my TWRP backup. xda’s BBS show absolutely nothing unusual, about 5% of being awake at screen-off-time which I consider a good result.
    Can that be explained? What I am supposed to do to get back my previous batt life? I hoped to get closer to 5h SoT that some reported to achieve, but it turned out it’s gotten much worse.



    Same here, my phone turned off one time at 10% on time on 15%. I tried to reset it by deleating the battery file with 100% battery and used till it turned off.. had around 25% left. something isnt right



    I have same problem.



    well, after investigating and experimenting I didn’t go any further than to do a clean flash. It helped indeed – I’m able to get 3-3h45 SoT within 36 hours

    still no idea what caused this



    ts is not work?



    I’m having the same problems with battery. Phone just drops from 25-30% to 0% and dies.



    I can confirm battery % problem on latest ROM.



    Same issue from a few days before.Turn off at about 25%.Still no idea.
    And wishing TS can solve this.



    I had the same issue, also the signal problems, so i flashed the firmware:
    The problems were fixed :)
