[HTC 10 Guides, News, & Discussion] nee24:
I am coming into this thread late I guess but I couldn't find another relevant thread so I will quote a few posts below. Hopefully someone can help me out and vice versa.

I used to have badge icons on apps before the update and it pissed me off on apps like facebook because I would have push notifications turned off there because I only want to know if there's something in there if I physically open the app. Now I am not getting badge icon notifications on any app. The worst part is not having them on phone, messages, whatsapp etc. This is supposed to be an added benefit of installing Oreo. So WTF. I've seen a few places mention it's because of using the sense launcher. Does anyone know if the google lancher will fix this? I don't actually want to change the launcher on my phone unless it's completely necessary.

This. I tried googling it previously too but couldn't find anything. I have sent 1 phone away to HTC for warranty battery replacement for the same thing. They sent back a refurb and the refurb had the top part of the screen not registering touch. Sent that away for warranty repair, they sent me a refurb and the refurb now has the same battery issue the first one did. A word of advice - don't leave home without the charger. I made the mistake, the phone started doing the reboot loop and I couldn't restart it again after that even after charging it to 100%. I lost everything on the phone. I had intended to back it up the next day so I could factory reset and see if that fixed the battery. Well, I had to factory reset to get it to start again, and the battery was still stuffed. So it is definitely the battery and judging from the one I have now, it is common.

I ended up buying a brand new HTC 10 (I love this phone) and am sending the old one away to get fixed again then will sell it.

Turning Sense home notifications on didn't help me unfortunately. Did you need to restart afterwards or something?

The funny thing is that my first HTC10 only started having the battery issues after updating to Nougat. Before that it was fine. HTC was never any help regarding the issue either. They just tried to get me to test certain apps, try safe mode etc then finally after factory reset didn't help, send the phone away.

The brand new HTC10 I bought a couple of weeks ago has AMAZING battery life. Overnight on 4G I'm getting only 1-2% battery drain, and that's with tonnes of activity/notifications in the morning. I no longer have to leave the house carrying portable batteries (I have 3 of them for the old phone) and I am not freaking out once my battery drops to 50%. In fact I leave my phone off charge over night sitting at 32% and when I wake up it's sitting at 30%. I just charge it when I get to work.

I am devo that this phone has been discontinued. I don't like the fact the new HTC flagships are so big (I also have a U Ultra as a work phone and it is MASSIVE, I hate it) or the fact they don't have a headphone jack. I am at least hoping this phone lasts me until they bring out a decent replacement. I have considered moving to pixel but there are things I don't like about that phone that stop me. I've had about 5 HTC phones in a row.

After the Oreo update my only issue is no badge icon notification count. If I can fix that I will be a happy camper.
