    Did fdr as well, didn't help. They broke something in the patch. My battery life has been horrible. I find restarting fixes it briefly so I have to do it every night to prevent massive drain overnight.

    Add me to the list.
    I did an FDR after the Oreo update, battery life was as before and excellent. After the patch / security update it's terrible. Just did an experiment and found that it used about 60% overnight whereas before it never used over 5%.
    Hopefully, someone and HTC figure this out. ( What's the best way to contact them? )

    I'm happy to report that in my case, the FDR did help with battery life, specifically with standby. It's now back to where it was before the update, at least so far. Fingers crossed that it remains that way.

    Mine was briefly fixed then the next day bad again. Basically a reboot fixes it for a short time.

    I'm also having significant battery drain on standby after the most recent update. Has anyone put in a ticket with HTC and received a reply?

    Just wanted to jump back in this thread and note that my U11's battery life has also reverted back to terrible, even after the factory reset. I'm just not sure what they broke, but standby is just horrid. I'm really hoping they fix it next time around -- the phone went from having great battery life to terrible battery life in one fell swoop.

    I know this sounds weird, but hear me out. I got into a car accident, nothing major but I had a concussion and some lacerations. I never(seriously, not one time, ever) let my phone battery completely discharge because I feel like it's bad for the battery. That night though, I was in the ER until 3 a.m. and obviously I didn't have much of a choice. The battery completely discharged and now, my two day battery life is back. Standby time has been great again as well. 1 day 15 hours on battery with 3 hours screen on time is pretty fantastic in my opinion. So maybe, just let your battery died so it can be reborn......
    HahahahahahahahahahaAaaaA
    Anyways, hope it helps.

    It is the reboot that temporarily fixes the issue but it will come back, usually after you make a phone call.

    I tried reboots. Cache Wipes. Those never worked. And I waited three days to post this in order to be sure it wasn't a fluke. I made about 13 phone calls between insurance adjusters, family members, friends and dealerships over the past few days. A lot of them I was on the phone for over 20 minutes each. Nothing has ever got my battery life back to this. I have no choice but to disregard your argument, considering how good my standby time has been over these last three days.

    This problem is being reported on every phone with oreo and believe to be an Android problem in general. I have read of temporary fixes but don't remember what they are as I haven't had any issues yet and hopefully I don't. I know they have discussed it in the forums over on XDA in the HTC mega thread under HTC U11.

    Honestly, I was on drugs so, I don't know. I know I slept until noon the next day. I can't remember if I powered my phone on or if I just put it on the charger and it was off the whole time it charged. Sorry, wish I could be more help.

    Just wanted to let you guys know that I contacted HTC tech support yesterday morning telling them about the drastic battery life change since the last update, and they pushed a new update to my phone just before noon today that was about 134 MB. I installed it and saw a big battery life improvement, with the phone going from 86% to 84% in two hours, and that included an hour of no service in a mall restaurant. I'm not sure if I'm the beta for this update today (Software number 2.42.617.6), but it definitely fixed the battery problem. I'm going to get back with HTC and let them know the results in a few.

    You may want to do a soft reset after the update. I did not, but it may help.
    The update is working very well for me. It's lunchtime and my phone has been off the charger for 6 hours with normal use, including a little Google Maps and a lot of music with some app updates, and the battery is still at at 92%.

    What's a soft reset again. That's not where you factory reset the phone is it. Is that where you just clear the chassis partition?

    why did I soft reset or soft reboot. I'll see how it goes and only thing I think I can do is is clear the chassis partition
    02-23-2018 01:28 PM
  24. usguyver's Avatar
    well I also a chassis partition wipe. that did not help it was only a 135 megabyte update so maybe there is more battery bugs than just one. I'm thinking about calling HTC as well and talking to the tech support.
