Yes i know... In realwolrd 1.2 or 1.4 it "Q.B." .... But some people like me really love to do some benchmark once in a will.... and just like me that people loved your kernel for the 1.8 ghz cpu and all the wonderfull tweaks you make.... i once seen one score on antutu with a greek with a u8800 and the cpu @ 1.9.... , i know it is only for benchmakr, but with miui and your kernel i am in 2 place in world rank from antutu for U8800 devices, if you wold rellease a kernel with 1.8 or 1.9 options for benchmark i think i could break the world recoard and WITH your kernel...

Can you help me achive this ?

@franciscofranco: Using Today's kernel (franco.kernel aug31) and miui (26/08), my phone just shutted down a couple of hours ago, during charging. At the time a setcpu profile was up, using ondemand governor, at 245/368 (or 768Mhz i can't remember, i deleted the profile right away). I only noticed it when tried to unlock the phone, only to realise it was switched off. I powered the phone up again and everything seems ok since then.

Should i be worried? Is there any log i could send you that could help ? It's a brand new 5days old ideos x5:P
[Huawei Ideos X5 U8800] rikobiff:
Finally, my BT headset works with music without dropouts!!

Thanks franciscofranco for this update, you rock!
[Huawei Ideos X5 U8800] AceDroidX:
Francisco may i ask why you have disabled some low frequencies?
[Huawei Ideos X5 U8800] ArbiterGR:
Bump and i just got a random reboot on the phone, using ondemand 245/1024Mhz while installing an APK. I think i'll revert back to yesterday's release.
[Huawei Ideos X5 U8800] franciscofranco:
Let's see what happens in the next update then. Would be nice to see you breaking the record with my kernel ;)

Nah. Forget these profiles Ondemand already has inbuilt profiles for screen off as well as the other governors.

I didn't, I just used the updated acpuclock-7x30.c from dzo. The voltage from the lowest frequency to 768 it's the same so it will surely use the same battery.

It's probably the ondemand governor since it's backported from the 3.0 kernel. Use Smartass2.
[Huawei Ideos X5 U8800] ArbiterGR:
Ah, good to know, got me worried there hehe :) Thanks for the response!
[Huawei Ideos X5 U8800] Averell:
Hi Franco,

Could you please help check this question?

Thanks!
[Huawei Ideos X5 U8800] ArbiterGR:
AFAIK, the battery stats bin file is located at "/data/system/batterystats.bin" and to my knowledge, it does not get overwritted or deleted automatically. You have to use CWM Recovery to wipe battery stats should you need to.
[Huawei Ideos X5 U8800] AceDroidX:
So if i got that right the vlotage is the same for frequencies up to 768Mhz.

So what's the point keeping the 2xxMhz freq? Even lower voltage?
[Huawei Ideos X5 U8800] franciscofranco:
Yes up to 768 the voltage is the same. Dunno, my frequencies are 768mhz/1,517ghz, always been, always will be.
[Huawei Ideos X5 U8800] NPC70199:
My (latest Miui + your latest kernel) runs with 245/1024mhz, use Smartass2. I disabled all connections last night. After 7h my akku lost 1%. I'm definitely very happy with this constellation.
[Huawei Ideos X5 U8800] Averell:
If it is in this folder, then when I wipe data, why it is not wiped?
[Huawei Ideos X5 U8800] AceDroidX:
Franco in MIUI we have this script... does it intervene with the ZRAM? Is ti wise to have them both or we have to chose one? If yes what do you recomend?
[Huawei Ideos X5 U8800] skifyr123:
AFAIK it is two different things.
[Huawei Ideos X5 U8800] tifozif1:
@franciscofranco thank you !

smartass2 rocks

I am using Oxygen r1 with FranciscoFranco kernel 31AUG. What is the Dalvik VM heap size ? How can I know this and how to change it to 48 or 64MB ?

Do you recommend this tool https://market.android.com/details?i...=search_result ?
[Huawei Ideos X5 U8800] anjo88:
In miui the max with this kernel is only 1.6 is it normal?
[Huawei Ideos X5 U8800] tiagovale2:
Yes it is.
[Huawei Ideos X5 U8800] Averell:
First time reached 1.5 days

I used Oxygen 2.2.2 v1 and Franco kernel Aug30. Is was the first time that my battery survived 1.5 days - from 12:00 to 23:30 of the next day, with push-mail on during working time + normal use.

Now trying kernel Aug31 with ZRAM initializer, hope that it will last even longer.

Thank Franco and Dzo and all!

Had "SmartAss2" with 200min and 1024max and the battery goes from 85% to 45% over the night :( I didn't had any wifi,bT, GPS or data enabled :( Anyone?
[Huawei Ideos X5 U8800] JaymzBond:
it clearly states the phone cant go into deep sleep

check your apps before having questions about your governor i say
[Huawei Ideos X5 U8800] mesnati:
what do i have to check? how do you "check" application?
[Huawei Ideos X5 U8800] andreasha:
This one can check if something is holding a wake lock http://xdaforums.com/showthread.php?t=1179809

If there are any better apps for checking apps that prevents deep sleep please do tell.
[Huawei Ideos X5 U8800] Vk_:
Correct me if I'm wrong, but if the voltage is the same up to 768Mhz, isn't it most battery friendly frequency to keep min. frequency at? I mean, even when governor caps the the frequency at min at screen-off, if it's set at 768, the phone can perform scheduled actions much faster but using same voltvoltage and go back to deep sleep, thus saving the battery?
[Huawei Ideos X5 U8800] andreasha:
Sounds like it should be like that yes, but there must be more to it or?

EDIT: Is it just our device that have the same voltage up to 768MHz? Is this the case on stock ROMs too?
[Huawei Ideos X5 U8800] vlc_marcos:
but isnt possible to put less voltage?
[Huawei Ideos X5 U8800] dzo:
Power is proportional to frequency and the square of the voltage so low frequencies do save power, but when the CPU is idle it goes into a very low power state (actually powered off) so for real usage cpufreq doesn't make a big difference. Also, the CPU voltages have usually been chosen after lots of testing so changing them may not be stable on all devices.
[Huawei Ideos X5 U8800] vlc_marcos:
Thanks for the explanation. Very good.
[Huawei Ideos X5 U8800] Vk_:
But is it better to let CPU run on higher frequencies during the background tasks (like scheduled email check, etc.) when screen is off, to enable it to go faster to deep sleep? Especially, if it uses same voltage (=eats same amount of battery?) as on lower (=slower?) ones?
[Huawei Ideos X5 U8800] Tommixoft:
those tasks not very uses cpu..it's more data I/O, wi-fi chip usage then cpu. Anyway there is governors and they automatically adjusts cpu as much as apps need. So if you set 0.2Ghz min and 1.5Ghz max -it will use what phone needs, but as i see in stats almost always it uses max freq for jobs, so it's not very good idea to overclock you cpu to 1.8 or 1.5. i think there is more than enough 1.2ghz.
[Huawei Ideos X5 U8800] andreasha:
But I read about problems like bad phone quailty when having set the min freq too low or how was it?
[Huawei Ideos X5 U8800] GolfCranK:
Franco seems to contradict this (or am I just misinterpreting what he is saying?)

http://xdaforums.com/showpost.php?p=17147154&postcount=473
[Huawei Ideos X5 U8800] :
I'm using MIUI 1.8.26 + latest FFRanco Kernel

CPU min 245Ghz and Max 800GHz

Governor in SmartassV2

I/O Scheduller = vr

and I don’t charge the battery the past 30hours (since yesterday 9am) and I still have 19%. I'm crazy with this battery performance and I'm always looking to the device to see if I still have battery lololol.

And as been with intensive use, calls, sms's, flashed room oxygen yesterday, go back to MIUI EN, after MIUI PT, a lots of benchmarks and battery still lives 19%!!!

Before, my battery couldn't last up to the end of the day.

It's and accomplishment.

Good work!

Regarding zram, isn't this already included in the ffranco kernel?
[Huawei Ideos X5 U8800] franciscofranco:
Not contradicting. dzo knows more than me that's for sure, but this is what I've gathered from two the two android phones that I've worked on:

Having the lowest possible frequency during sleep time it's not good. It takes longer to wake up and it takes longer to enter idle state. What we want is the phone to enter idle as fast as possible. It's been tested by me and a lot of other people with decent knowledge that it wastes more battery having the lowest frequency with the screen off because the time that it takes to ramp up the frequency and then ramping down and entering idle is way bigger than having a higher frequency as the minimum.

That is what I've defended for a long time and I gotta say that it works, I never ever had any problem with my batteries time, I can have them last as long as I want.

dzo is right on what he says, don't make a mistake on that, but that's just the tiny bit of the iceberg. We want the phone to enter idle as fast as possible. The fastest it gets there the more battery it saves.
[Huawei Ideos X5 U8800] andreasha:
@franciscofranco do you use ~200MHz as your lowest freq or do you go higher?
[Huawei Ideos X5 U8800] levibuko:
he said that he uses 756/1516 smartass v2 with vr
[Huawei Ideos X5 U8800] Tommixoft:
after reading his post i think he uses 460mhz :)
[Huawei Ideos X5 U8800] clpdj:
Im in your side Franco... i tested this myself and from what i have tested the baterry last longer if the freq. min ar set to ~600 mhz.... this results in faster responce for people like you and me that use the phone regulary, obviosly if you compare apples with apples and you let 2 phones from 100% to 0% battery, one using 700mhz and the other with 122mhz and dont touch on it the 122mhz will last longer.... but if you spend time turning on and off the device it wold be more long lasting the 700mhz....

just my 2 cent
[Huawei Ideos X5 U8800] andreasha:
And were back to the argument if you disable everything like data, sync and not use your phone quite often then why have smartphone ;)

So what min freq. do you normally use (daily usage)?
[Huawei Ideos X5 U8800] franciscofranco:
I use and always used 768/1,517 and I use the phone very regulary. The only thing I don't use because I don't need it is Auto-sync and data. I sync when I want to, I don't want stupid apps to sync it for me when they feel like to. And no data because I have wifi 90% of the time, or at home, or at the mall, or some coffee where I can steal someone's wifi. So there you go ;)
[Huawei Ideos X5 U8800] clpdj:
I use 768/1800 but i am i performance freak and i use all the power i can (i benc alot)

i use the phone like you franco, no auto sync, and 80% data sybc from wifi... but i bench 2 in 2 days ore even every day....

I am willing to be in the firt place on antutu rank.... With your help franco ;)
[Huawei Ideos X5 U8800] JoseRebelo:
Doesn't wifi drain your battery quickly? If I have wifi turned on the battery goes down very fast.

I think there is the option "gTxPowerCap" in the file /system/etc/firmware/wlan/qcom_cfg.ini, wouldn't lowering this make the battery last longer when wifi was on? (I don't how much this affects the wifi range) I think i changed something like it on my N95 to save battery, and the range and speed were not affected that much.
[Huawei Ideos X5 U8800] Tommixoft:
Smartphone is smart because he have OS, not because of wi-fi or 3G. Why you need wi-fi turned on if you don't use it? switch it on when you need and switch off when you've done. Why there is need for full brightness? outside the house it's barely seen so no metter, and indoor is more then ok to have 25% of brightness :)

And why use phone as computer? we all have pc so why we play games on phone or surfing on the web when we are at home? :)

And it's VERY bad for your health too!! wi-fi and cellular radiation is bad.
[Huawei Ideos X5 U8800] franciscofranco:
As I said I can have the battery last for as much as I want. If I want 3 days I'll make it last 3 days, if I want it to last 10 hours I can make it so.

I don't mess with that TX power **** because if I lower it I'll lose my wifi at home because my router is a bit far from my room, but yes technically its more battery friendly with a lower value.
[Huawei Ideos X5 U8800] andreasha:
Haha sorry if I stirred you guys up, it was a joke :D

10 % battery drained in 15 mins
[Huawei Ideos X5 U8800] vlc_marcos:
Wow is a lot. But doing what?
[Huawei Ideos X5 U8800] Tommixoft:
Best is 460Mhz. I use program cpuspy and before i used 245Mhz and in cpuspy there was many uses of difereent hiegher freq. as 700 and so on, after i set 460mhz - all i see is Deep Sleep, 460mhz and the highest [1.2Ghz] freq. So it's more optimal cause now phone does not use 800 and 700 freq. :)

Governor is ONDEMAND.
[Huawei Ideos X5 U8800] shantam:
Only wifi and xda app plus browser brightness is set to auto
[Huawei Ideos X5 U8800] franciscofranco:
Why are you giving false information. There is no best frequency, there is optimal frequencies, not THE best. And yes the phone uses 800 and 700 frequencies if you set it so. Ondemand wastes more battery than smartass2 or minmax for example.
[Huawei Ideos X5 U8800] Tommixoft:
I don't agree with that. Smartass too much ofen changes freq of cpu and that's is not very efective in terms of battery saving. Ondemand works more like min max but not so often on max as MinMAX. So ONDEMAND is better for battery. (i did not tried smartass2, my rom do not support your kernel right now).

Maybe for me ONDEMAND is better cause i do not play games with phone or something like that.
[Huawei Ideos X5 U8800] randomparanoia:
I use min/max all the time and so far for me I got the best results in terms of battery life. Over 50 hours with 768/1200mhz and still 30%. Its true, I didnt use the phone as much these last 2 days but even though nice results with couple of calls, running app and some mp3/youtube.
[Huawei Ideos X5 U8800] GolfCranK:
Can someone tell me what zram does. Should I flash it? What sort of user benefits from it?

Thanks.
[Huawei Ideos X5 U8800] Tommixoft:
If you use Ideos x5 then zRam is uselless because you have enough RAM for your apps. zRAM is virtual ram with some nice features. Anyway if your phone most of the time have more then 100MB of RAM then you will notice nothing after installing this. And i think only in CM7 ROM there is settings to set how much % use as zRAM.

I may be wrong, i'm only week into linux android stuff.

ondeman i lost 5% of battery per 10hours :) so not governor important but the usage :D If you don't use it no metter what governor is set.
[Huawei Ideos X5 U8800] entrapmen:
My phone started to loose battery very fast after i flashed the 31aug kernel (with zram).

I look cpuspy and it seems its in the deep sleep mode mostly but i almost loose %20 after unplugged the cable.

[Huawei Ideos X5 U8800] Tommixoft:
Battery last long ONLY with one condition and this condition only - if LCD is turned off. If lcd is on you can use any gov.any freq - it will not help much, cause lcd is biggest power consumer [i normal daily basis usage, not gaming, or cpu testing]. And 245mhz is too low so i'm doubted that in cpu spy you will see that phone uses that freq.
[Huawei Ideos X5 U8800] fr0stebyte:
i'm using 122mhz and spy does show it spends alot of time on it.

I'll post pics later.

122mhz 9hours

DeepSleep 40h
[Huawei Ideos X5 U8800] andreasha:
How much screen on time?
[Huawei Ideos X5 U8800] Tommixoft:
9 hours on min and 8hours on max? IT's VERY BAD! ratio is almost 1:1

Mine is 4% on max and 26% on min (460Mhz) and almost all the rest on sleep.
[Huawei Ideos X5 U8800] fr0stebyte:
Depends on your use. Gaming and wifi from time to time.

As said smartass sends surges to the cpu.

I got my screen on auto, but probably almost a full day using it then put the phone to sleep
[Huawei Ideos X5 U8800] Tommixoft:
if gaming and wi-fi and it last more than 18 hours then it's not bad :) Mine only lasts 30hours just on sms messaging.
[Huawei Ideos X5 U8800] entrapmen:
I tried to lower the cpu freqs but that change nothing. I've tried ondemand, smartassv2 and some other governers but that didnt help either.

When i close the wifi it somehow reduce the battery usage. I'm not sure what's causing this but it killed my day. It just doesnt drain battery, it gets warm and warm (from the bottom of phone).

What's at the bottom? Cpu? Wireless card? It makes me nut.

I tried to force close, reboot, hard reboot, wifi close, gps was always close, data on/off, so on. Nothing helps. Battery finished before night (i unplugged the phone at about 1 pm and it finished at 10pm that means 9 hours of usage -mostly on deep sleep-).

Thats too weird, i never had that kinda problem before trying 31 august ff kernel -with zram- on miui latest.

Any advice would be appreciated.
[Huawei Ideos X5 U8800] Tommixoft:
Just open battery usage info and the top using thing will be your answer [thing that causes problem]. If it's Andrid system than the heating thing is cpu. My stock rom had this problem it drained battery 50% per 30minutes and phone was hot! And in battery usage Android System was using 99% of battery usually is not more than 20%].

So look what is using battery the most. Also you can get cpu cpy and look what freq is used the most if highest then heat is from cpu.

I suggest you to reflash your ROM.
[Huawei Ideos X5 U8800] entrapmen:
I did have look battery usage but nothing enormous was there. It was as usual, %40 android system, %15 navigation, %5 camera and like that...

I checked with cpu spy, it was on deep sleep for 6 hours, 30 min 1200 mhz, 2 hours 700 mhz and some others.

I wiped everything and do a clean install of latest miui. I'm gonna look without FF kernel this time if it's kernel or rom.

[Huawei Ideos X5 U8800] Tommixoft:
Wiping stats never did anything for me, i can wipe and battery after reboot is still the same amount as before wipe. All li-ion batteries have chip that tells info. Anyway, huawei batteries are ****, i don't think they really are 1500. It's too quickly draining. From 100% to 70% is very quick. And too quickly recharges it don't need even 2 hours.
[Huawei Ideos X5 U8800] katu2006:
Wiping the battery stats doesn't affect the reading straight away. The purpose of the battery wipe is to make the system aware that the readings could be incorrect.

What usually happens, if you don't wipe the battery stats, the new Rom installed is estimating based on the previous collections that your battery is fully charged, when in reality your battery could be 80% charged, therefore your battery life is shortened.

I recommend battery wipe for every new installation, even if it's the same Rom. For me, it usually ads about 10h of battery life, but in time...not straight away.

Also, I would recommend charging via USB, even tho is taking 3-4 h...it will lead to a better battery life.
[Huawei Ideos X5 U8800] ArbiterGR:
What he said. Also you should know that if you're on the MIUI rom, somehow that specific rom drains way more battery than oxygen/stock. I don't have anything to back this statement up, just real life usage. But at the end of the day, as franco said, how you use your phone determines its battery consumption.

And lastly, Huawei's batteries are as good as anyone else's is.
[Huawei Ideos X5 U8800] Pelemane:
U8800 has Li-Po battery, not Li-ion. And stock charger is 1000mA so of course it takes less than 2 hours to charge.
[Huawei Ideos X5 U8800] andreasha:
Isn't Li-ion better?

Sent from my Ideos x5
[Huawei Ideos X5 U8800] ArbiterGR:
Not really. Think li-po batteries as an improvement to li-ion. Its major difference is how the energy is stored inside the battery. Li-po batteries use dry cells, where as li-ion use liquid fluid. Basically the huge difference between the two, is that li-polymer batteries can be created in different sizes and shapes more easily than li-ion.

Performance wise, a let's say 1800mAh Li-po battery will last as much as a 1800mAh li-ion one.
[Huawei Ideos X5 U8800] Tommixoft:
No meter li-ion or Li-pol the idea is the same - both have chip :) And li-po is also li-ion [Lithium-ion polymer] so... :D

And i don't think that charging via usb is better. USB is very low in ampers as i remenber usb standart it's about 250mA. BUT maybe volts are important here not ampers..so then no metter. But usb power supply is varying depends on how much other stuff is plugged in other usb ports, and it's also not good to have varying power supply when charging.
[Huawei Ideos X5 U8800] katu2006:
I'm sorry, this has become offtopic, but you're wrong about USB recharging...A device can draw 500mA from a USB port ( http://en.wikipedia.org/wiki/Usb ) that's why it takes twice the time to recharge the full battery, comparing to the wall-charger.

Voltage is NOT changing (USB gives 5V constantly), therefore it's not important. Current is the one that matters and that's the one charging the battery. Every mobile device since 2009 has a power regulator inside, so varying CURRENT doesn't affect the battery anymore.

It's better to recharge via USB because the higher the Current that flows through it the higher the chances of damaging the cells and reducing the battery life.

Didn't you notice that recharging the phone via wall-charger gets the back really hot?

When charging via USB, the phone gets pretty hot as well, but it's nowhere near compared to wall-charger. My advice is, if you care about this phone, start using the USB charger.
