Hey guys.
I'm planning to get Htc One M8 soon and after reading reviews and watching videos I'm not sure If I should update it to Lollipop when I get it. Some poeple say the update is great, however other say that the phone overheats, lags and the battery life is much shorter. I would very appriciate if u guys can help me out, say which one do u prefer, which one is better. Im looking forward to get some answers from everyday htc users not admins or something. So what I care about is:
*Performance
*Any lags?
*Battery life (Important)
*Temperature (Important)
*Camera (heard its worst in Lollipop, i dont know if its just a rumor)
P.S. sorry for my english, not my native language.

I think performance wise, there isn't much difference when I updated. My reasons for preferring Kit Kat are due to aesthetic/functionality changes that I didn't like.

I'm running lollipop and I don't have the problem you speak of speed and performance I don't see the difference benchmarks are a different matter

Can you guys tell me about the battery life and if the temperature of the phone is higher after update?

And does anyone know of a good Kitkat 4.4.4 based ROM I can flash?

I'm a frequent visitor. Currently running CM12

Which one do you recommend?

I don't know if it's available for the M8, but I'm running Candy Rom. It's based on CM12 with extra tweaks. Smooth and stable. It's not KitKat though.

Ok thanks, CM12 is definitely the best Lollipop ROM imo.

I was hoping to find something similar to CM11 as I know Kitkat has better battery

I'm sure there are some KitKat based roms for the M8. Check the threads and read a few pages over at XDA. That will give you a good idea what people are experiencing. But CM12 runs so good that I can't imagine going back to KK. I couldn't go back if I wanted, as there are no KK roms for the Nexus 6.

You are right about cm12 I'm using it on a nexus5 really smooth and fast

I agree, I think I will stick out CM12 until I get more stable reports on CM12.1

I don't know much about the M8 rom-wise, but it could be harder to develop for since it is not as open as say a Nexus device. That's why Nexus devices have the best development as far as #'s of roms available and bug fixing. It should go without saying that a Nexus device is easier to work on since it is Google's own flagship device. It's one of the main reasons I've owned the HTC G1, Nexus One, Nexus 4, 5, and now 6. Complete freedom and ease of use. Consider getting the next Nexus phone if you really want to get the most out of roms and customizing.

I don't know much about flashing roms in general, but I have seen several people posting they love one called Viper. So there's something to look into besides CM.

There's a TON of roms out there. Try a bunch.

My stock M8 with KK was perfect in every way. Since Lollipop was forced to my phone i have had all kinds off problems. Hoping to root it at some point so i can either go back to KK, or find another ROM that will play nice with my phone.

Please stick to the topic from the OP.

Love Lollipop on my M8 HK edition. Everything works fast and smooth and wouldn't dream of going backwards.....

Thanks

I was unsure at first, but I do like Lollipop better than Kit Kat now. I have two M8's and was able to update one and not the other. I can say with the phones side by side, Lollipop is definitely faster, and not because of the animations either. Apps run faster. Battery life drops for the first few days, then balances out. After a week, Lollipop has better battery life. My phone, right now, is at 50% after 36 hours of run time. AVERAGE screen on time is 6 hours, 35 minutes, with the maximum SOT for a single charge being at 9 hours 35 minutes.

How do you get such battery life? Since the Lollipop update my battery sucks

[stkorn97]

Lollipop works good for me. Kit Kat also worked well. I like the changes of Lollipop. Battery life is about the same for me all around which was usually good for 2 days before needing a charge based on my usage.

[badelhas]

I did a factory reset but my battery life is much worse. I really don't understand what else can I do

I had a typo: it was 50% after 36 hours. Still pretty good though. I just do the basics, like drop down the quick setting menu and pop off mobile data, Bluetooth, and GPS when not needed. I'm not anal about it, but if I know I'm going to not use something for a couple hours, I'll turn it off. Oh, and I use Battery Monitor to let me know when it's done charging. An alert goes off at 100%, and I'll let it stay on for another ten minutes then unplug it. It seems to like that. Ironically, my wife leaves her junk on all the time and still gets through the day with 40% or more left. I think what's also important is making sure all your apps play nicely. I install apps one at a time so I can notice if they have bad battery behavior. There are several apps I've deleted because battery life tanked after they were installed, and it shows up in the battery manager as well. For example, TubeMate used to be bad and I would disable it until it was needed, but now it's fixed and I can le it be. The video app by Polycomm for video conferences still is bad, and it just sits in a disabled state most of the time.
