Battery needs optimization

After 7 days of with the phone in my pocket, I think battery needs some serious optimization. Compared to my previous device Redmi note 6 pro on 4000mah had a lot better battery than Mi note 10 at 5260mah. Battery is draining like too fast. I'm on xiaomi eu btw.

I sincerely hope Xiaomi fixes this battery issue with a firmware update. A 5000+mah battery with a mid tier chipset should give phenomenal life.
I think we should get together and make some noise to get Xiaomi to address this. Tech reviewers are blaming the UI

I must agree on this. The battery life leaves a lot to be desired. Thought it would be amazing, but it's only marginally better than my old Nokia 7 Plus.. And the battery in that one is 3800mah.
Please optimize the software Xiaomi!

Yeah after rooting i did some digging. There is some kernel optimisation needed.
Example: Min freq is not set to 300mhz but to 5xx mhz. Also there is some kind of cpu boost enbled (i wasnt yet able to disable it) which is way too agressive, this also causes the min freq to get stuck at 13xx mhz. This cna only be solved by rebooting

Do you suggest taking parameters for this? Or just wait for a Major update?

Actually I am impressed by how long the battery lasts on my Mi note 10
Using it basically no stop, with screen on 90% if the timer and using GPS, chats and emails and more, in the evening I still have not less than 40%

Interesting discovery. While snooping around I found these posts talking about the Pixel 3 and OnePlus 6 that also idle at 576mhz. Both use the Snapdragon 845 though

Yeah exactly. But thats not that big problem, if you watch your CPU Stats you can see your idle freq get stuck at 13xx for both clusters. Thats quite high for idling. Also did look into the released kernel source, but couldnt find the problem

Not the biggest fan of things like LKT, but in this case it works. Sets the cpu to 300mhz and gets rid of the 12xxmhz boost! if any one want to try it aswell

Your phones guys have really some problems. Mine is rooted and twrp. Updated. The rest is all stock. Yesterday I used it like crazy. Google map for about 2.5 hours, screen during the day basically always on cause I use whatsapp for work. I also spent 1 hour playing a game. In the evening I had 41% battery.
This phone have a monster battery! Amazing!

I would like to feel the same optimism that you feel, but until now, I cannot. I got my phone 2 days ago, 2 full charges, one gave me 8h of SOT and the other 7h of SOT. There is something wrong here. I had more battery life with the Pocophone I had than with Mi note 10. Let's see if in a future update it gets better

I mean yes it has good battery life and i can get easily 2 days. But its a 5xxx mah battery. It can last longer. Its like upgraing from 1liter to 2liters but only using 1.5 Liters.

Its Never a 5xxx Battery

Thinking about it, 4000mah sounds right. The Oppo Reno2 has a 4000mah battery, uses the same 730G chipset and has about the same screen size.
The GSMarena endurance test gave the Oppo Reno2 a 102hr endurance rating.
The Mi Note 10 scored 95hrs endurance rating.
I think we've been duped here

yes. any xiaomi device It has that. The only option is the force setting set min. 300mhz on APK like ex Kernel menager. And turning off boost Touch
Check mi room or miuimix rom based on China dev. I use mi Rom on cc9 and k20 pro. The battery is much better than xiaomi.eu

Question Rog 3 Temperature

Hi, I want to buy the Rog 5 but I've heard that it has high temperatures even from light use (like when using YouTube it reaches 40degrees celcius). How are the overall thermals? I'm not talking about throttling I'm talking about general temperature when using the phone for light tasks. Any info would be highly appreciated. Also any info on battery life would be great too

From what I have heard from Youtube and reddit, It is a hot phone because it keeps internals in a good temperature, plus they achieved better temperature after update.

But having a warm phone isn't a good sign is it? I'm currently using a huawei p40 pro plus and it's super cool (probably because of the ceramic body). You mentioned an update, so is the rog 5 cooler after the update? On YouTube Technick ran a battery drain test and the Rog 5's peak temp was almost 60 degrees celcius

Thanks man. This really helped.

I got it a few days back, I can share some impressions. Yes, it's a hot phone. Yes CPU temp gets up to about 40 degrees sometimes when browsing or multitasking. Gaming also gets it to about 45 - 50 on CODM and Dead Cells and between 55 and upwards of 60 with Genshin Impact. A Peltier effect cooler like the FunCooler from black shark brings this down about 10 degrees. This temperature is mostly felt at the center of the display, while the sides on the back, where the batteries are, remain noticeably cooler. Perhaps their goal was to dissipate het through the display, idk.
I haven't been able to notice any drop in performance yet, even with the thermal limit set to low. What I don't know is how this affects the chip long term, but I hope it doesn't degrade for at least about 5 years. Either way I'm sticking with a cooler for Genshin impact just to make sure the device lasts longer.

Thanks for the reply. 40 degrees from just web browsing is ridiculous. Rather dangerously high and will definitely degrade batteries. Think I'll give the rog 5 a miss

40 is the CPU reading I get. Batteries stay about 5 degrees below the CPU for normal use generally according to my observations, just to make that clear. Not sure which battery temp it's actually reading though, since there are 2 batteries.

40 is still too high though for normal usage. I've never heard of a phone go that warm. My huawei sits at 22 maximum.

Phone arrived 2 days ago, in my experience It Is not that hot, while browsing / YouTube / Instagram It Is cool (about 31/32 °c) and my ambient temperature Is around 20 °. I have played 1 hour call of duty and It reached 37 ° on the cpu, while the phone was hotter, especially in the middle. I think this Is how It works, getting hot outside to be colder inside. Also I updated to firmware 2102.81 which helped a lot.

When Samsung developed the Exynos 2200 it was supposed to power the central core clockspeed at 1.9GHz. After they finalized development (or possibly before they finalized development) they discovered any speed over 1.34 GHz generated unacceptable overheating. Instead of re-engineering the SoC they decide to throttle the crap out of it. In the meantime they've been tampering with the other cores in an attempt to find an acceptable balance. I would submit to date those efforts have failed. Welcome to the wonderful world of Exynos!

And I don't understand why people are still buying devices with Exynos from Samsung..Only because it's a Samsung? Don't get me wrong, I would go instantly to Huawei if they would have again GMS, because I really loved my P30 Pro, but without GMS my only alternative it's Samsung since other brands are having a lot of things that annoy me.

Welcome to Exynos !
btw, 35 isn't high. my a3 usually heats up at 40-60 (when playing games) and also has an exynos processor (Exynos 7580)

Get Good Guardians and install Thermal Guardian.
It will let you change the thermal profile, like if you are in a hot day or cold place. Also logs all the apps that might warm your device, then you can turn problem apps off or set more battery savings aka less power, aka less temp.

i found when converting .vob to .mp4 on the device it gets very hot, but of course that is quite an intensive task, i would be interested to know how a snapdragon version handles that

Snapdragon!! Very useful to Cook egs, with exynos in the last ten years and for note (with s22) never seen a minimal rise in temperature

What CPU temp does your phone reach?

Mine is 36.2ºC when idle, but reaching 41ºC on shell and battery temp. while lightly browsing / telegram.
I'm on Snapdragon 765G 5G.
Is that temperature normal ?

In my opinion yes, it's should be normal.

Thanks for the quick answer.
I was a little nervous since the phone has always been quite cool, and since updating to A12 I can feel the heat way more, even through the case...

Mine is 31ºC when idle. The CPU is Snapdragon 8 Gen 1.

Development [MOD]Thermal-Throttling-Modifier[Pixel 7 Pro]

Code:
/*
* Your warranty is now void.
* I am not responsible for bricked devices thermonuclear war, or you getting fired because the alarm app failed
* Please do some research if you have any concerns about what this MOD does before flashing it
* YOU are choosing to make these modifications, don't point fingers at me if something goes wrong
*/
Ladies and gentlemen,
A small modification for you with great and HOT results.​
Changes I made to the thermal configuration:
-The default Virtual-SKIN-based throttling threshold was starting at 39 Celsius, that was removed and the first threshold value is now 55 Celsius (at 55C it will HARD throttle, throttling is not completely eliminated here on purpose and at 55C it will behave the same as the default throttling mechanism at that temperature).
Keep in mind that SOC will throttle regardless of when it hits its own TjMax values so you don't need to worry about any "meltdown". lol
- Display won't switch to 60Hz anymore and neither will the maximal possible brightness be reduced as it is normally happening with stock throttling thresholds.
So far I'm using this on EvoX ROM but this should work basically on ANY ROM as the throttling is relying on the same file and as far as I managed to observe (amount of ROMs checked out) it's the same on those ROMs.
Pros:
- Throttling thresholds are drastically increased, meaning if you experienced any HIGH FPS drops during playing any "heavy" games, this will prevent that from happening to an extent and time.
- Any apps that rely on high processing power, will have more space and time to work without being affected by thermal throttling
Cons:
- Depending on your usage and what exactly you do on your phone, the device could get uncomfortably warm in your hands, and battery temperature will raise MORE than you got used to it since the SOC won't be throttled that fast as it does on the stock. Keep in mind that high battery temps are not healthy, and they will cause faster degradation. Degradation occurs anyways, the question is only how fast based on the temps the battery is being exposed to. Many OEMs allow such temps, so, Pixel 7 series with this mod isn't anything different compared to them.
- If you're a heavy "gamer" and play some games like Genshin, TOF, COD (at 120fps), etc... (you'll have a smoother experience (less FPS drops) based on slower/weaker throttling) but I recommend always using a Peltier cooler to keep that battery and the device as cool as possible (regardless if this phone or another).
Why did I create this mod?
I personally use an app called MotionCam Pro. It's basically a RAW video recording app that relies on HIGH processing power (it records RAW DNG frames) and it heats up the device pretty fast, well, Pixel 7 Pro hits the throttling threshold really fast and it's causing the recording to drop A LOT of frames to a point that the footage recorded is not "usable".
With this mod, I can now shoot RAW videos for longer periods with almost no dropped frames and under higher ambient temps. Yes, the phone warms up much more, but it does the JOB for me and that's all that matters to me anyway. I don't care if I'll need to replace my battery after 1 year instead of 2 years because I lost maybe 15-20% of the battery capacity (I upgrade my phones almost yearly).
Have fun frying eggs on your phone.

Is it possible to change threshold around 41 Celsius? 55 Celsius is quite hard temp for me, but 39 is to low. I think best for me will be around 41 ~ 42. Thanks for reply

There actually is. Open up the phone, remove the "heatsink" from the SOC, and add liquid nitrogen to keep the CPU under 30c degrees.
What device has a CPU temperature lower than 30 Celsius degrees? That doesn't even happen in idle mode, and especially not with passively cooled CPU/GPUs

Of course, it depends on the ambient temperature a lot. Don't take it literally, but you know what I meant.
As soon as you touch your phone it will start spiking way above 40c and under some load instantly 50c+.
Tensor G2's default TjMax is 100c. YES, 100c.

Thank you for this, makes things much more bearable. Stock thermal throttling is really bad.

Indeed. I'm not a fan of the "heat", but I would rather bear with the heat on the surface of the phone than have a completely crippled phone when it hits the throttling threshold. As I mentioned, the apps I use are completely useless when that happens.

yes dropping frames when using android auto and want to record something is really annoying because phone get 40C while using android auto and you can miss good video while driving

I'm really interested in knowing how you use the MotionCam on Pixel 7 Pro. i tried it and edited the footage with the app itself and it turned out to be super noisy. Any tutorial would be awesome.
Also, do you know if it's possible for Pixel 7 Pro to get DC Dimming?

This is unfortunately not compatible with TD1A.220804.031 - causes phone to hang on G with progress bar

It seems a little counter intuitive, but my phone stays cooler in standby with this mod. I believe it is because it no longer throttles during longer tasks in the background, like photo or DropBox syncs. Of course it also heats up more while gaming, but the performance also doesn't degrade. Thanks for this OP!

You can test it and let us know.
I'm not on STOCK ROM. Also, I doubt Google did a big change when it comes to thermal configuration, so it should work.
Since it's a magisk module, it's easy to test, if it doesn't work, it can be removed.
