    Default HTC One (M8): Please explain High Performance Mode

    Hello,

    I recently came across a website that was talking about the extreme power saving mode on the M8 and it is not available on my current software number of 1.55.605.2 but will be available on 1.55.631.4. During this I searched in the faq on my device about this mode. I came a crossed this

    (Why are Power saver and Extreme power saving mode both grayed out?

    This happens when you turn on High performance mode under Developer options in Settings.
    High performance mode requires additional battery power to maximize CPU performance. In this mode, both the Power saver and Extreme power saving mode features won't be available. If you want to use these features, turn off High performance mode.)

    Naturally I searched how to enable the developer settings
    (HTC One M8 High Performance Mode developer options - PC Advisor ) and turned on High Performance Mode. Then I was searching and saw a lot about benchmark apps a etc.

    My question is what is a benchmark app and what does the HPM actually do? If anyone can shed some light and let me know.

    Thanks
    Joe

    A benchmark app would be like Antutu, and a benchmark is a point of reference that multiple devices can be compared to. High performance mode, I would guess, overclocks the CPU to attain faster performance. If this were the case, that would go along with the reason that you can't have battery saving and and overclocked CPU.

    Has anybody used the high performance setting? Does it make much of a difference and how much of an impact does it have on battery consumption?

    I used it today. Download the Antutu Benchmark app. https://play.google.com/store/apps/d...utu.ABenchMark

    Try it with and without it. There is a difference. I tried playing a racing game with and without. With it seemed a little smoother. And yes battery level goes down quickly. I'm just waiting to the update so I can use the extreme battery savor

    Is this not available on the AT&T model? I can't find it in my developer settings.

    I tried it for a little bit. It does improve the performance at the cost of battery life.

    I'm on AT&T as well and I don't have this option in the developer settings

    You don't have the high performance mode option? Did you get to your developer options by hitting the build 6 times?

    Yes I did, still no sign of the high performance mode.

    Yup, I've activated developer options and no high performance setting on my AT&T variant

    Well I guess that's more of a reason to switch to Verizon. Lol. That's really strange. Wonder why AT&T did that?

    Nah I'll keep my stock browser, Verizon versions removed it. Plus AT&T has better coverage in my area

    It's a completely useless feature unless you're benchmarking or want to use your phone as a heater

    Well it's in Developer Options for a reason, and Developer Options was hidden by default recently for a reason. I'm assuming AT&T didn't want people messing with it and then complaining about battery life. Of course, why Verizon would allow it and NOT allow Power Saving modes, in addition to removing the stock browser, doesn't make any sense.

    Regardless, I would agree that it's not really a necessary setting, and unless you need to test a new app that you made or have an extremely demanding game, the slight performance increase wouldn't be worth the battery drain.

    Well, since the at&t version doesn't have power saver either, maybe those features are controlled by the program, and once the update with power saver hits well also see boost mode.

    AT&T variants have power saver mode, just not extreme power saver. Verizon versions don't even have regular power saver mode

    Hello, I don't know how many years or days you have posted this ago, I forgot to check, so I'm just going to answer it as if it didn't matter when you asked. Now that is 2016, phones do more and more, my M8 tends to lag only though in this one scenario, where it has been disconnected from Internet and out of touch, and once I get it connected back, all of a sudden all the apps want to know what is up, and with all the services and apps I use, that tends to be the one and only thing that can bring this King of performance down to its knees for maximum of 10 seconds, before it catches up, but those 10 seconds, as we all know, are the key seconds when we actually want to use the phone, so I thought I'd try the Performance Mode. And unbelievably, now it is gone, the one time HTC M8 gets to lag, and with Performance Mode it's eliminated, due to removal of temperature/clock throttling. Because it is for those few seconds only, the phone doesn't get a chance to heat up noticeably, but I recommend turning off Performance Mode during gaming, because this phone can push any game to date flawlessly, and because when you remove this throttling by enabling Performance Mode, the phone will get real hot, as games will constantly take advantage of that extra power and they're not coded to monitor temperatures, but it isn't necessary to enable it unless a game really lags, but due to heat and constant higher CPU clock usage you'll drain more power because of that.
    Great news is that Performance Mode doesn't really impact battery life at all for normal use aside from gaming, because the CPU is only really pushed to the max during those first few seconds of use, which is where the notable difference is.
    My fiancé and I had the same complaint, both being on M8's, we didn't have it a year ago, interestingly, but I guess with times we do need more processing, and there is our proof.
    Hope this answers. Cheers!

    Hi, You mentioned that it's gone. Is that due to an update? I'm still on Kitkat 4.4.4. Just want to know if they have removed it from an update if so which one.
