HTC One M8 - Marshmallow Sluggish Performance

I have noticed, since my M8 was update to Marshmallow, that its sluggish (slight delay most functions) when opening apps, refreshing and receiving emails, (office365 and Gmail). I have factory rest the phone and still see this. The phone is working fine, other then the sluggish performance. Is anyone else experiencing this?

I apologize for the delay, KevinB2014. These community forums are intended to be more of a peer-to-peer forum than immediate assistance from Customer Service. The suggestion Marcus made could absolutely be something that you or anyone else that comes to this forum for assistance on this same issue can benefit from.

After any big update, such as moving to Lollipop or to Marshmallow, occurs certain parts of the system memory gets altered. Application memory needs time to optimize and can cause the device to temporarily use more battery. On average it'll take about 3 days for new software to optimize its performance and battery life to normalize. If it's taking longer, many times this is caused by 3rd party application updates being needed as well.

Since some of your downloaded applications may not be optimized for Lollipop (developers don't always update their applications immediately to support new versions) this may also result in higher than normal battery drain until the application is updated or removed too. Try going into the Play Store > My Apps and making sure all the applications have received their updates recently. Additionally, try going to Settings > Manage Apps and clearing the cache (tap the app, then tap Clear Cache) on some of your more frequently used apps, like Facebook.

I just upgraded to Marshmallow. I use my HTC M8 with my TriCaster 8000 to stream our church services. It works great when I use the HTC as a Hot Spot but I need to tether the HTC to my Asus RT-AC3200 Router. The tether sets up fine and works with my Asus Router but the upload speed goes from 2 mbps as a Hot Spot to 200-300 kbps when tethered. I experience the same type response with the download speed. Can anyone help?

mlamx1634, This is not the direction we want after an update. When you did the Factory Reset, did you disable the "Automatic restore" option (testing without apps coming right back)? Could you test the phone in Safe Mode? http://spr.ly/6581B5VzV

I tested the HTC M8 in safe mode today. I tethered it to my Asus RT-AC3200 Router.

My HTC had 3 bars(-99 dBm) of 4G signal strength.

I tested the upload speed with testmy.net and I saw the following results:

Test #1 474 Kbps

Test #2 155 Kbps

Test #3 861 Kbps

Test #4 1.4 Mbps

Test #5 1.2 Mbps

Test #5 1.5 Mbps

II then Restarted my HTC in Normal Mode and tethered it to my Asus Router with the following results:

Test #1 1.7 Mbps

Test #2 1.7 Mbps

Test #3 1.4 Mbps

Test #4 406 Kbps

Test #5 1.4 Mbps

Test #6 1.7 Mbps

At this point I decided to try Live Streaming a 700 Kbps video. It worked and kept working for an hour. I am satisfied that I'll be able to stream this Sunday.

Thank you for you reply.

I would call it a performance disaster. Everything takes 10 seconds to inititiate action. I want my Lollipop back. This upgrade is typical verizon bloatware.....no useful new features and ridiculously slow response.

Verizon, is there help on the way? I loved my HTC One M8 before the Marshmallow upgrade. Now it is so sluggish I feel like I regressed 5 years. I realize you may not have a solution yet, but can you at least keep us updated on what is going on? Is Marshmallow a bust on all devices, or just HTC One M8s?

slb5146

Not sure why others are having a problem but since I have been tethering my M8 with my Asus Router for a couple weeks successfully I am satisfied with Marshmallow. I have been able to stream our church services for 3 hours at 700 kbps for the past two weeks with my TriCaster 8000 connected to my Asus Router.

I have not noticed anything about my M8 or my wife's as being sluggish. We both use them a lot everyday and we are satisfied.

Someone had replied,is this happening on all devices,or just HTC One m8 phones.good thing I'm eligible for a new phone,cause I don't know how much longer I can use this phone.

KevinB2014

A few months after I bought the M8, I believe it was about October, 2014, there was a major upgrade pushed to my M8. Was that Lollipop? (How soon the memories fade!) Anyway, in addition to some cool new features, there were some performance issues, some apps more than others. Within a few weeks, a flood of app updates were made, and I believe also one or two Android updates, and things got better. That's what I'm hoping happens here. It wouldn't be unreasonable for Marshmallow to introduce some performance issues to many/most apps that would require some minor tweaks for those apps to return to peak performance. That's why I'm asking whether we should just be patient for a few more days/weeks, or if we should be alarmed that no one thinks there is a problem and this is the new normal.

I have a ton of apps. People who don't have many running in the background might not have the issues I have. Perhaps Marshmallow, or problems with a lot of apps not behaving efficiently with Marshmallow, has caused my system to be sluggish due to the CPU being too busy? But I would think if that were the case my battery would be draining fast, and this is not the case.

I hope someone knowledgeable from Verizon eventually responds. Thanks.

I cured my problems first by disabling wireless and realizing it performed

great on 4G. I had to reboot my network router and then restart wireless

and all was right with my Marshmallow world.

I'm glad I'm not the only one. While there is a definite overall sluggishness, my biggest problem is that half the time when I turn the screen on, it takes 2-3s to come up to full brightness so I can see to unlock it.

I hope we can get a fix as I like this phone and I don't want to buy a new one just yet

Mario64, thanks for reaching out for help. I know it has to be uncomfortable dealing with those issues. Lets work on this. Please go to Settings > App manager and select ALL. Scroll down the list of applications and select “Android System Webview” then select Uninstall.

Then restart the phone and let us know if this helps out.

It's becoming clear that this isn't the way to get a phone problem resolved. It took 48 hours for ukpylot to even get a response, and if you two dialog back and forth, this could take a month. No one's even responded yet to any of my posts on this thread.

So should we call Verizon tech support and do this over the phone? I came here to this message board figuring the problems would be widespread and well-understood by now. Doesn't sound like anyone knows how to resolve the sluggish Marshmallow O/S problems on HTC One M8s yet.

MarcusS_VZW suggested something to try to Mario64 several messages ago. Is that something I should try as well?
