Best kernel for battery life with Fresh 3.1.0.2?

I've never cared about battery life before because I'm typically near a charger however I'm going to the beach for a few days and will need my phone to last.
What's the best kernel/set up for me if I'm running Fresh 3.1.0.2? I don't care about performance, fps, mflops, etc for these few days as long as the battery lasts and the phone is stable. I have setcpu on my phone but don't really know how to use it.

The latest cfs kernels are supposed to focus more on battery life than performance. Do you underclock cuz that's a big help too.

At 998 max now, where should I be? Which cfs one?

I'm running Fresh and Netarchy's 4.1.8 kernel.Creating a set CPU profile for when the phones screen is off will increase your battery life quite a bit.My screen off profile has the CPU max at 245 ghz and the min at 128.You can also scale back your max from 998 mhz to around 500 mhz and save battery without your phone being so slow that its really noticeable during normal use.

Interesting. What kind of battery life do you get? I thought I read a while back that going below 245 was a bad idea. Guess not?

It's more stable with the newest kernels. I'm set at 245 min and max when the screen is off and I usually see a 1% loss every couple hours but I haven't paid a lot of attention to it lately cuz like you, I'm usually near a charger. Battery life while using the phone still isn't great but I kind of expect that from a phone like this. There are some good battery conditioning tutorials in the forum that help quite a bit too.

Here's my usage for the last week.I go off charger at around 7am and usually have about 70% charge remaining when I get home at 5.

[Q] HTC reduced cpu frequency in update?

Hello, I heard that HTC reduced the processor frequency in "One X", due to the high temperature of tegra and battery lifetime (In update, maybe 1.29?). Is that true?
Sorry, but my english isn't good.

My AnTuTu score went up so I'm guessing not.

not reduced just doesn't ramp up as often as before

Thank for answers
I didn't know that antutu shows the cpu frequency

Did they change the CPU scaling governor?
I remember talk a little while back about On Demand and Interactive governors and which one was best

antutu only shows what the max speed is and its only 1.5 on a single core, when on 4 cores you can only get 1.2 GHZ and 1.4 GHZ on 2 cores.
look at terga stats at bottom on screens
4 cores bench

So reduced frequency it's true? Earlier (after updates) unless Tegra 3 had 1.3ghz on 4 cores ?

No It's always been like this, the update changes how the CPU speeds up and down e.g 50 MHz in idle to max speed, all its done is help the phone use the lowest possible speed to save battery.

How hot can the htc one x be?

Hello guys.
I'v rooted my Phone and switching between rom sens 4.1.2 and cm10. But that's not the case.
I know that the hox can be hot some times. But i want to know how hot it can be?
Was playing a game and my Phone got to 46c°
Is it too hot?
Reagards zardox!
Sent from my HTC One X using xda premium

The only hotter thing than the HOX is my girlfriend, bro.
Normally 46° is nothing for a piece of hardware, on its camera side there is a bit of overheat while using in games etc, but normally it won't get hot, just a bit warm.
Did you use a stock kernel for sense 4.1.2 and cm10? If yes, you shouln't worry about your smartphone getting to hot.

I've gotten my HoX over 55 degrees C, without problems. Though.. When I reach that heat, I often stop playing games, since my fingers will get hurt quickly by then.
It wont matter that much, just make sure it won't happen 24/7

will changing ROM or maybe flashing Custom ROm fix heating ? mine spiked up to 48-50c earlier while playing dragon slayer

I had my htc one x go upto 49c. If u are using a case for ur hox I would suggest u to remove it when u feel ur phones getting too hot, this might help.
Prolonged high temperature might not damage ur phone but will reduce ur battery life cycle.

At 48 c is when the "overheat" green/red notification while charging starts, however most phone batteries are rated for ~60 c.

you guys do know that 50~55c is actually the temperature of the battery right? The actual temperature of the processor can go beyond 75c. System Tuner can detect the CPU temperature.

The widget with the android logo is System Tuner showing CPU temp while the one next to it is Battery Monitor Widget showing battery temp. This was taken after 10 minutes of Glowball

I flashed ARHD V15 and suddenly when I surfed the net it went to 55.5C!!!

65 C maxim when playing a game .

Ah okej! =) Thx for the awnser guys!

CPU speed for Snapdragon 808 1.44GHz?

So today got my replacement new G4. Dowloaded the CPU Z app and it shows my cpu at 1.44. But my benchmarks in antutu are fine.

Or are you serious?

Can someone check theirs and see hat it says? I think i know whats going on. The two cores 4 and 5 are the 1.8GHz and 0-3 are the slower cores.

It's hard to catch 4 & 5 doing much of anything, so I launched a huge game that takes some time to load, switched back to CPU-Z, and snapped a quick screenshot. The apps just report the max CPU frequency incorrectly. They probably just need to be updated for the 808.

That's because you aren't doing anything....
Take your thumb and scroll up and down fast and you'll see it go up.

My thumb wasn't fast enough to get 4 & 5 above 1.4 GHz while taking a screenshot. Launching a big app was a lot easier. Obviously 4 & 5 do move some, but the concern was that they were capped at 1.4 GHz since all of the apps show that as the max CPU frequency.

It's the governor and cpu control that does this - it regulates speed for temperature and battery control by changing the value in sys file system, so cpu monitors that read that once and treat it static will always get a false value.

Here are couple of screenshots showing the 2 high power cores 4&5 at their maximum speed of 1.82GHz. As well as their speed history.
I used System Tuner app from the Play Store. You don't need root to use the app to monitor system usage.

What's normal battery Temp?

Hey Everyone was wondering what's the normal temperature for the battery? Here's a screenshot I took, I use the app called Devcheck great app by the way, great for getting all the Info you need about your phone.

that temp is good, nothing to worry, everything up to 37/38 without gaming is quite normal. it depends whether you use mobile network and a lot of browsing or so or not.everything starting from 38 and above should be only reached with gaming

No need to worry about temperatures on the phone. It's not like a desktop with variable cooling systems. If battery or CPU is getting hot, it'll throttle to lower temps and will turn off in extreme conditions. Having Android phones since the D1, I've never seen anyone fry their phone from excessive temperature.
IMO, monitoring temperature on phones is as useless as ram cleaners. Let the software do it's job.

What's the normal Temperature of the Battery?
Room temperature obviously!
Everything else i abnormal. Like when you activate the screen and use your phone. This uses energy and causes the battery to become warmer.
Using a LOT of energy like Recording 4k or playing a Game which uses up to 8W will increase battery temperature.
1. the 8W Electrical energy get turned into 99.9% thermal energy, the SoC is between battery and Display, facing the battery IIRC.
2. The Battery being used causes itself to heat up.
So what is the Limit? Around 45°C The phone starts throttling CPU clocks and GPU clocks way earlier. Around 38°C is the first one and around 41-42° he next one. But depending on your surround temperature (Jep, Texas Sun at noon and 35°C Outside temperature do not help....) your phonebattery will not get hotter than 48°C
Is this safe? Jup easily, the battery iself should be specced about 50-60°C Maximum usage temperature. Didn't really take a look at the details in the battery in the disassembly video^^
But as Richii already mentioned, your phone does this all on its own. Don't have to care at all
It's note a Note 7 ^^
