why is this processor so battery hungry? - Xiaomi Redmi Pro Guides, News, & Discussion

I previosly owned a Moto X Play and it didnt consumed more than 3% and at redmi pro is minimum 12% . Data and wifi always enabled

There's definitely something with the thermal management of the processor, as evidenced by the difference in Antutu scores hot vs cold where I see 30% difference, low 70000 versus > 100000 - and by "hot" I mean after 10 minutes of browsing, not playing intense games.
That said, compared to a similar spec phone like Elephone S8 the Redmi Pro looks pretty good. With a similar battery rating and X25 if I leave both idle the Redmi Pro still has 35% charge when the Elephone S8 hits zero. Yes the Elephone has a larger screen, but by idle I mean mostly just sitting there with the screen off.
Can't comment on the Moto X Play but if the Snapdragon 615 is anything like the 625 in, say, the Redmi Note 4X then battery life will blow it out of the water and performance will remain pretty much constant (it never gets "hot hot"). But... so here's the thing, in Antutu the performance never reaches the heights of the X25 at it's hottest/worst.

Honor 6 overheating

Hi, i have my honor 6 for a few days now and i really like it, but it is heating up very fast. After recording a video for 4 minutes battery temperature goes up to 37°C and cpu temperature rises up to 60°C and it gets really hot. Even when only browsing it gets hot as ****, battery 36°C and one of the cpu sensors shows even 58°C only while normal browsing in chrome with two tabs, no other tabs open and it doesnt even have 20 degrees in my room. So how are your cpu and battery temperatures of your honor 6? And do your honors also heat up? And what are normal temperatures for this device for cpu and temperature? I have the european variant and updated to emotion ui 3.0 if this matters. And phone was in airlplane mode while testing this. Ive read that the heating goes away after a few charging cycles, can anyone confirm this? My old g2 never got comparably hot to the honor 6 even when playing games. So do you have similar temperatures on your honors and it is normal that the honor 6 heats up quite more than other phones?

Anyone had doubts between: Xiaomi Mi4C & Asus Zenphone 2 (and can share)?

Hi,
Curretnly i'm on the G3 and i dont like it much.
Thinking on 1 of these:
Xiaomi Mi4C
Asus Zenphone 2
Now, I asking that in Mi 4C Thread bc's i thinking that there is some people that might had this.
What do you think?
Thanks!
It comes down to preference really as I dont really like phones bigger than 5" and xiaomi is quite established. Its got the right size, ir blaster and a good SOC which should get good rom support, cm12.1 already available
Where are you based? The Global version of the Zenphone 2 has band 20 which the Mi 4c doesn't have (may be able to be unlocked manually but I'm doubtful). The Zenphone also has expandable storage which the Mi 4c lacks - you may already be used to this and the larger form factor due to currently using the G3. That said, I've heard (but cannot personally verify) that the Zenphone has erratic battery life and performance in addition to being more expensive than the Mi 4c.
ermacwins & wingsfortheirsmiles,
I got used to 5.5" so this is not an issue at all...
I from Israel and LTE bands are 1800 & 2600.
So from my understanding, both of them would work, right?
32gb are more than I need, so the expandable storage is not too important.
If the Zenphone do has erratic battery life and performance, it's a good reason to go for the Mi4C, isn't?
Anyone else suffered or heard on it?
Thanks very much!

Well, my Mi4C had battery drain. Around 3%/hour on idle with WiFi and 4G all off, so when I woke up a third of my battery was already gone. I ended up fixing it by flashing the international ROM but after that, I've been getting 5 hours of SoT which is great. Can't comment on the battery of the Zenfone.
Regarding the battery problem:
Looks like it could different between your's to anyone else.
I read a review in a site in my country and the person who made the review praise the battery life.
Thanks!
My Mi4c has very good battery life. The same like the z1 compact i had. Other phones i had i charged sometimes more than 2 times a day.
The zenfone 2 has worse battery life, build quality and performance. If you don't mind the SD card and 5" screen then the Mi4C is your phone. Zenfone 3 could be very interesting when (should be kinda soonTM) it gets released though!
Thank you all!
Go for the Mi4C.
P.S: A newer model of Mi series also coming soon?
How abt Redmi note 3?
No battery issue with my Mi4C. Left it idle for most part of the day with cellular and Wi-Fi connected the whole time and managed 0.7% / hour idle time. I also have many apps installed (not facebook or any messaging apps though). It's rooted and greenified, running original stable Chinese Miui 7 Rom with some Chinese bloat apps removed. It's also scoring 52K on antutu 6.

Processing power wise, ZenFone 2 (the high end 32 GB internal memory with 4 GB RAM model) is comparable to Mi4C, the GPU is even slightly better. However, when it comes to video recording, ZenFone is waaaaay below Mi4C. The still image, if you use latest firmware, is already fixed though. Note that due to the use of Intel processor, some apps that use native libraries might not be installable. Ensure your apps are architecture-neutral or have both arm and intel version available.
OTOH, Mi4C has thermal issues and I still can't find the best thermal configuration so far. This causes the cores, both CPU and GPU, get shutted down or their upper limit is decreased to lower down the temperature. I break this limit by changing the limit a little bit higher, but if you play games while charging the phone, my best record reaches 90° C. Hot enough for a sleep killer tea
Happy deciding!
Having owned both phones i can say the Zen2 is a dud. The screen is dim, the speaker is weak, some apps drain crazy battery as they are using an ARM emulator to run on x86. It wobbles on the desk and the battery dies after your lunch break. The camera has low exposure that makes everything look darker than it is. The Mi4c just works like you expect a flagship to do.

I dont believe in 90° C unless your phone is borked and termal throttling doesnt work, also phone would shut down anyway with that temperature.

It is, well the screenshot I have is 87 actually in one of the many thermal zone (they're all varying from 60 or so) but during that time I did see and feel 90 (as a hot tea drinker, I know how hot is 90). Thankfully I have a flip cover that absorbs the heat, but if you touch the scree, it's really damn hot. Thermal throttling doesn't work on my device, because I've disabled the thermal driver :cyclops:
I don't really know the actual upper limit, but I guess it should be around 100-120. My PC was 120, but I don't think smartphone's SoC will differ much.

Hahaha, worry not, it's been back to normal temp (30-50). The problem only happens if you play resource intensive games while charging.
My last phone Mi4i also reached ~90°C after playing with the thermal engine. The flashlight turned on in the pocket of my pants and burned for half an hour. I just noticed it because my leg got hotter and hotter luckily the phone wasnt damaged through this. Also, i think the CPU can handle these temperatures without being damaged, but i would worry about other phone components such as SD Card, battery or glued components
Sorry, my antutu 6 score for my Mi4c was 685xx, not 52k.

Heat

Some phones are great to take camping because if you play Asphalt 8 long enough, the back warms up to the ideal temperature that can bake bread. Rate this thread to express the extent to which the Moto G5 Plus stays cool under extended heavy use. A higher rating indicates that even when playing strenuous games for long periods of time, the phone doesn't get uncomfortably warm.
Then, drop a comment if you have anything to add!
Coming from a Nexus 6 (which had a Snapdragon 8xx or something), it's been great having the G5 Plus with it's slower-more-efficient processor. My favorite games (DomiNations) used to heat up my Nexus 6 like crazy. I never notice heat for my G5 Plus.
When on Android Auto with Spotify and Google Maps running, I get some heat on the back of my Moto
My Moto X Play got really hot once it was doing something but my Moto G5 Plus no matter what it is doing it just never get hot, it may feel slightly warmer occasionally but that's about it.
Same here one of the best things I've noticed first. The LG g5 heated up like crazy....probably what caused it's demise.

Guys my moto g5 plus temperature is somewhere between 33 to 36 on normal usage and standby , it feels warm.
does anyone feels the same?

Completely normal, unless the ambient temp is 10C or something... I haven't seen temps get above 40C ever on this device, but won't be concerned until close to 50C.

High SoC Temperatures

so according to JerryRigEverything Teardown of the Mix 3, there is thermal paste on the SoC to lower the temps, however according to Antutu and CPU-Z sensors my SD 845 reaches 40-45 ALOT during light use; almost at idle being 36-40C, as high as 50C a couple of times, and 45-47C average during gaming opposite to my previous Honor Play which topped out at 42C after like 2 games of Pubg and ranges from 30-35C normal light use.
my antutu scores aren't suffering though my average is 295,000. (a bit higher than other SD845 phones that aren't "gaming" phones)
is it normal for SD 845? since it boosts to 2.8 GHZ
is it xiaomi pushing the SoC a bit to gain an edge? more heat due to more sustained boost for example.
faulty phone?
on the other side, my battery temps are low, like 28-30C idle, 30-32C light use and like 33-36C gaming & wirless charging

Question x3 pro about undervolting....

hi people i am curious about undervolting and underclocking. is there a possibility that i can make my phone more enerrgy saver?? i don't need too much performance, i am just playing pubg at lowest settings 60fps and thee phone gives more than i need (i think). So... i need enough performance and longer battery life. what can i do
The biggest power consumer in the device is probably the display and not the CPU/GPU. Even if you undervolt, it's only a few millivolts anyway and that would hardly do anything. Setting the display as dark as possible would probably be the most efficient, although this won't work miracles either.

but i've got more when undervolted mi 9t pro.. by the way there is just a different cpu (732g vs 860) between x3 nfc and pro. And snapdragon 778 has adreno 642L gpu and it's TDP is 5w (860's is 10w). ANYWAY What is the difference between x3 nfc and pro?? x3 nfc has 10 hrs screen on time and x3 pro has approx. 7hrs. WHY???

x3 nfc has about half processing power of x3 pro, that alone will make huge difference.

Of course, the CPU/GPU of the X3 NFC (5W TDP) consumes significantly less power compared to the X3 Pro (10W TDP), which means that the Screen On Time is higher compared to the X3 Pro. A computer with a Core i3 CPU and a GTX 1650 Super also consumes less power than a Core i7 with a RTX 3060 Ti. You can of course undervolt the CPU/GPU of the X3 Pro, but you will probably never get the power consumption close to the X3 NFC. The cores architecture, clock rates, the internal memory and the memory bus + RAM speed used in both devices are also different, so that you can't really compare them.
The SD860 is about twice as fast as the SD732G (at least in synthetic gaming benchmarks), so it should be clear that this additional performance has to be bought with additional consumption somehow.

They are very similar but not identical. Nevertheless, the guide for the 9T Pro should probably serve as a good reference. In any case, make a backup beforehand, every chip reacts differently. I wish you the best of luck and let us know how it turned out.

For undervolting you would probably need a custom kernel.

Underclocking is not worth it.
I did a full-time test on NoGravity Kernel with PC Mark. Way worse performance and a ridiculous 30minutes gain (minimum screen brightness)
Left is normal balanced Profile. Right is battery saver with reduced maximum frequency.

Approximately half of the CPU cores would have to be deactivated completely and even then the 720g would probably still have the edge in terms of power consumption, because the GPU of the SD860 also has three times as many shader units as that of the 720g and accordingly it consumes more power.
Years ago I played around a lot with UC/UV on smartphones, but in the end it wasn't really worth it. And it seems that it's still not worth the effort, as Haldi4803 has shown with his post.

Battery saver preset already reduces big cores to 1400mhz or something like that.
You see performance from 12'000 to 8'500 which is about 30% performance drop. But there is no 30% Battery life increase, but only 3%.
Might be different for GPU underclocking. But I haven't really taken a lookt at that,as I don't play games on my phone.

No. Both started properly at 100%. The app just fails.
You can see the 2nd screenshot go down to 20% at Pass 80 but then still going over pass 120.

Thank you
i got two simple solutions.
1) set framerate in pubg to smooth and low at the beginning of the game. when you go for fights just increase it to extreme. also set low framerate in lobby. this will definitely keep device cool and save a lot of battery.
2) use venella os and freeze all the apps with icebox app. leave only few apps this will also makes device cooler while playing games personally i have noticed calyx os keeps this device very cool.
