Battery life REALLY bad after overclocking.
 

hey i have overclocked my phone and its on ideal settings 500min and 850 max. after overclock at first i thought the battery life improved but now it lasts for only 6 hours. with 2,3 calls and wifi and internet radio for 1,2 hours only. why is this? and i havent seen SIGNIFICANT improvement in speed after clocking. sometimes i feel its not even overclocked. my settings for ideal are locked and default profile has ideal settings. what should i do? and i have set low brightness and wifi has power saving on and its interval is set to never and phone is on 2g all the time.
thanks you. help would be appreciated

Re: Battery life REALLY bad after overclocking.
 

yasirrfc, no offence intended but why do you do this? You have proven time and time again to do stuff you don't understand and then complain when you don't like it. If you are not comfortable in getting into the innards of the OS, then you should leave well alone.

Did you even read any of the warnings about messing with the -devel repository?

I and several others have tried to help you in the past and yet you leave very little feedback or thanks.

For those that wish to help you, what are the exact steps you have taken to fix your problem? Which threads have you read to try to help yourself? What was the outcome of the steps you took?

Re: Battery life REALLY bad after overclocking.
 

How old is your battery? Maybe the overclocking has nothing to do with it...
I run ideal with [500,805] for quite some time now, and battery life is pretty good.

Re: Battery life REALLY bad after overclocking.
 

Do you run apps in the backround? What mediaplayer do you use (if any)? Are you connected to wireless all the time? Is GPS on all the time? How old is your battery? How often do you charge it?

You can try LV settings (low power), this will make your N900 run on 250/600 but lower voltage, so longer battery life (also slower). You should install Auto Disconnect and set it up to disconnect from any network after 5-10mins. Disable BT, disable GPS, and listen to MP3 instead of internet radio. Check out your homescreen widgets and remove CPU-hogs like Facebook. Now you should last 12-14 hours with 3-4 hours of ebook reading while listening to MP3, 1-2 hours of surfing the net (with Opera 11, turbo on), 20-30 mins of calls, and 30mins of AngryBirds. Also go and get a replacement battery, or even better an external charger like the Justmobile Gum Pro, that is good for 3 charges (4400mAh).

Did you edit those presets of Qcpufreq ? If yes , did you removed 0:20,200 frequency ?

Re: Battery life REALLY bad after overclocking.
 

i tend to lower everything when im not using the phone [ force of habbit i guess] turn the screen brightness down to the lowest, lower the cpu to 250mhz and have smart reflex enabled, this will increase your battery exceedingly, pity there isnt an app that could do all this for me but oh well d=

Re: Battery life REALLY bad after overclocking.
 

Try changing your overclock settings.
If your phone can handle running at starving/modified XLV, why not?
Just keep testing and remember, the battery life on the N900 is plain awful. Thankfully the overclocking thread came, and we're able to lower the voltages.

Re: Battery life REALLY bad after overclocking.
 

I posted a thread with some novel battery-saving ideas here:

Re: Battery life REALLY bad after overclocking.
 

hey the battery is not that old. i got the phone 1 month back so yeah. and im not running any such apps in background. yes i use wifi but for only 1, 1.5 hours. hey so on low voltage modes, if i keep the cpu to 500 and 850, then will it be more speedy and use less voltage?
thanks

Re: Battery life REALLY bad after overclocking.
 

Obviously you have installed somthing that is causing massive amounts of wake ups and stopping the phone going into standby. You have two choices.

1. a. Figure out how to use Powertop, top, ps, kill, apt-get remove.
b. Diagnose fault and rectify.

2. Backup your contacts and just reflash that mthfckr. Watch what you install next time around.


If you search for 'powertop' in powersearch you will find lots of threads of users attempting to 'hand hold' people through diagnosing the fault...it NEVER turns out well. (unless your name is switch_, but he had some prior linux knowledge.)

Re: Battery life REALLY bad after overclocking.
 

- Make a backup
- Reflash it to stock settings PR 1.3
- Order a Scud battery, use search button
- Stay off devel and testing repo's
- If you require the power kernel, see the wiki for optimised settings
- enjoy

Re: Battery life REALLY bad after overclocking.
 

Hi.

I'm still not sure if it's bettter to run 250/900 or 500/900.
The voltage of 500 Mhz is just slightly higher (30 and 33) for me, but it seems that the battery life is a good deal lower.
Is 500 Mhz so much more snappy for you or why are u using it ?

Re: Battery life REALLY bad after overclocking.
 

Power=Frequency*Voltage^2

that means the power use increase is exponential with respect to the voltage setting.

If you want total max battery to the max, set smart reflex to 1 and clock 250-805. (Smart reflex wont clock any higher than 805)

Re: Battery life REALLY bad after overclocking.
 

lol @ vi_
saw three post related to battery issue and saw three similar posts from vi_ in reply of them :D

Re: Battery life REALLY bad after overclocking.
 

ok but i heard that smart reflex reboots the phone a couple of times? and setting the lowest to 250 and max to 805 will still be speedy? like will it feel like its overclocked and is fast? and will this be in the ideal settings?

Re: Battery life REALLY bad after overclocking.
 

See the second post - the one from JohnLF especially this bit:
Or is this thread going to turn into your WiFi problem where you just ignore the advice given to you and repeatedly open new posts with the exact same question?

Re: Battery life REALLY bad after overclocking.
 

You should learn to read. You read that some people reboot with smart reflex. Some people don't. I recently cut my max to 750 and added smart reflex with good results so far.

Ideal isn't ideal for everyone. If you want settings you don't have to think about or understand, don't overclock.

Re: Battery life REALLY bad after overclocking.
 

Re: Battery life REALLY bad after overclocking.
 

hey i turned on smart reflex. but phone is acting wierd. reboots and is acting weird.i actually want the min to be 500 as it is better than 125 or 250 ans more responsive. i want max 805 and 850. ive tried lv and xlv settings but no luck in battery usage

Re: Battery life REALLY bad after overclocking.
 

hey my desktop battery widget shows a different percentage and the status bar shows diff battery percentage. i think its because of bq27x00. any solution??

Re: Battery life REALLY bad after overclocking.
 

Okay. First of all please stop starting your sentences with 'hey'. You are asking for help, please be more polite. Also I'm pretty sure that every language starts the sentences with a capital letter, and ends it with a period. So lets try again!

No. :p

Re: Battery life REALLY bad after overclocking.
 

ok sorry but no solution? :'(

Re: Battery life REALLY bad after overclocking.
 

Nobody said there is no solution. Try search.

@vi_
Where is that graph from? My digging seems to suggest that from 900 MHz on all voltages are the same on each profile, suggesting that from 900 on the graphs should coincide. My data old?

Re: Battery life REALLY bad after overclocking.
 

I think the graph was created by 'tonism', the bro who developed the starving profile(?).

It can be found here

Whether it is correct or not is another question, however it is good for giving a visual representation (as graphs generally do) of the voltages across the standard profiles.

Re: Battery life REALLY bad after overclocking.
 

Dude, I will say it again: you are going to have really hard time with this device and your attitude. I'm not even sure if you're serious or just trolling...

Re: Battery life REALLY bad after overclocking.
 

At least you haven't had private messages from him like I have, asking me to hurry up and answer his thread replies less than an hour after posting. I cut my ties pretty quickly there...

Re: Battery life REALLY bad after overclocking.
 

im not trolling. im trying to make the best of this device. ive succeeded in so many things that my friends are impressed by me. ive made things working for them that they dont know how to.im not a developer nor a pro. if u dont wanna help me, then ill try on my own like i have been. had so many problems before. when didnt get the right solution, it somehow managed to do it on my own or just lived with the problem. any help would be appreciated rather than trolling comments. no offence.
thank you

Re: Battery life REALLY bad after overclocking.
 

And there we have it, the response you get for offering help in the first place. :confused:
Goodbye!

Re: Battery life REALLY bad after overclocking.
 

Ok, so that's what I can add non-off-topic to your problem:
- It is not overclocking problem. It's just not the case here, believe me.
- You probably have some daemon running in the background. If you are curious, you can read about what a deamon is here: http://en.wikipedia.org/wiki/Daemon_%28computing%29
- QUESTION: You could run on your device:
Note that / is different character, than \. And also it is "ps" followed by space, followed by "-A" followed by space, followed by ">", followed by space, followed by "/home/user/MyDocs/runningprocesses.txt" (I remember you might encounter problems typing commands in terminal, last time you forgot important part of command I asked you to type ;) ). It will create a file on your N900 storage, so when you connect your N900 to your computer and open it from your computer, you should see file "runningprocesses.txt" in it's main directory. Please attach it here. If you cannot see or find this file, read my instruction again and repeat the whole process, if it's still not there - you are making a mistake somewhere and please don't ask here why it's not working and you cannot see any file like this.
- I can be wrong (and probably am), but if I were you, I would try searching CSSU thread for similar reports of battery drainage (if you have CSSU installed), because it may be the problem (just may, please don't be mad at me CSSU devs pretty please ;) ).
- From my own experience with my phone (your experience may differ): it may be tracker or thumbnailer indexing crazy like there is no tommorow.
- QUESTION: Did you install some extra protocols for contacts and conversations? I'm again only just guessing, but I remember that (especially msn protocols) some of them were in the past (LOL, I tried them ~1.5 year ago so it might have changed) trying to connect to the Internet constantly and constantly running in the background. It may also happen if you have Pidgin installed and turned on (you know that to turn this baby off you need to actually select "Quit" from it's app menu, because just closing the window makes it stay turned on for eternity?)

I didn't mean to be rude writing this post, so also please don't feel offended, I was trying to be nice and explain everything ;)

Edit: Your attitude towards JohnLF (he was trying to help in at least one other thread and you didn't even listen to him and didn't answer him and now you offend him and call him "sh*t") makes me a sad panda :( That's just wrong...

Re: Battery life REALLY bad after overclocking.
 

hey thank you. trust me i have tried everything. i havent used online im for 5 days now and i have wifi switcher when i heard there is a bug in n900 so its off most of the time when im not using. it disables all the wifi drives when it says wlan disable (the wifi switcher) and every app and the update cssu firmware was before the overclocking when i used to get battery life. now AFTER the kernel and the overclocking, i THINK this is the case. but im also searching for this new bug (i think) that when i enabled bq27x00_battery, it drained battery like crazy. and now the battery widget on my desktop and the battery in my status bar are totally different percentages. the status bar shows like 12 percent whereas the widget shows 59 percent. this HAS happened because of bq27x00_battery, not that sure about the battery draining. if u know any information on this, then do tell. and i am trying all voltages and frequencies and have tried smartreflex as well but well lets see if i manage to get some more info on the recent bug that i think is the problem.
thanks

oh and about that sh*t thing, he was messing around with me since day 1. i had a problem, he commented DONT use extras-devel and testing. its not for u. it IS for me. i know what im doing and its my device. i AM the owner and when i get problems, i come here and research or post threads so that people like u can help me with. that is one of the things what maemo.org is about.

Re: Battery life REALLY bad after overclocking.
 

Two things:
1. The kernel module bq27x00_battery DIDN'T drain battery like crazy. It just caused some software to read incorrect values but battery was NOT! draining even SLIGHTLY faster. The solution is and rebooting your phone - then battery widget and status bar and EVERYTHING shows the same and correct value.

2. You ignored all my questions and requests from my previous post and without answering them, I will not be able to help any more in this case and I doubt anyone will be able to add anything worth attention here without your answer to my questions from previous post.

Re: Battery life REALLY bad after overclocking.
 

for all who are interessted in power-savin :)

come to our thread ;)

Re: Battery life REALLY bad after overclocking.
 

oh and one more thing. one week back, when my phone showed like 0.4 percent battery, i could go on for like MAX 3 songs then dead. now after overclocking, at 0.4 percent, it played music for 1.5 hours and took some snaps off fcamera then died. though battery IS poor after overclocking but it is weird as well.

Re: Battery life REALLY bad after overclocking.
 

yes i will answer your question in 5 mins. oh and i did try that solution an hour back but it wasnt it. i tried it and rebooting but it was the same

Re: Battery life REALLY bad after overclocking.
 

hey yes i do have extras protocol but not pidgin. though i havent used the IM conversations for past 5 days

Re: Battery life REALLY bad after overclocking.
 

Try removing them and see if battery drainage still occurs. The IM system (and whole Maemo system) is designed in a way that you don't need to run conversations or contacts or other apps, some deamons are just started at system startup (so when you power on your phone) and keep running in the background even if you don't need them. Knowing that you have extras-devel enabled I would try:
- removing extra protocols
- disabling extras-devel and extras-testing and leaving enabled just normal extras repository (just for a while)
- refreshing application lists from repositories
- installing extra protocols, so you will sure you have the version from Extras, not from Extras-devel. Version in Extras is tested and reported stable.
- re-enabling extras-testing and extras-devel if you really want to.

Also, don't update extra protocols support later, as it will download version from extras-devel, which may cause battery drainage (because some part of conversations runs all the time, even when you don't use Conversations application).

Re: Battery life REALLY bad after overclocking.
 

hey thanks i will try this. any idea about the 0.4 percent battery time issue?

Re: Battery life REALLY bad after overclocking.
 

Yes. Previously when it showed 0.4% it was actually more. It is a bug with the bq27x00_battery module, some software then reports incorrect battery percentage. So you could do so much with 0.4% before because it was more (maybe 10%? maybe even 15%) and then when it showed 0.4% in the second situation, it might really be 0.4%. It is bug known to power kernel dev (devs?), because it was reported and discussed in power kernel thread earlier. It will be probably fixed somehow in future power kernel releases.

Re: Battery life REALLY bad after overclocking.
 

ok i did what u told me to. charged it around 3 am it was charged and 11 am its showing 45 percent
