HTC Hero :: Overclocking Vs Battery Usage
Aug 27, 2010
Soo running the froydvillain 1.4.4 tried different kernels. Would ask this on their IRC channel but I think they would lynch me :P The max stable I get is 748 was running it for like 10 mins :P (768 wont boot) Was running mostly 691 and now 614 . But dont know what will the difference in power consumption be. For example when playing with the phone and it will have to go to the 691 will it hold a lot less? Or its just a minor difference?

I realize how much faster the hero can be when its wimpy processor is overclocked. I would imagine that ocerclocking would be bad for it though, to push the CPU faster than its made to be, but most people don't mind it. I'm wondering, realistically, if it is hard on the CPU to be overclocked and also how it affects battery life. Keep in mind, I'm talking about overclocking the ROMs made to be like zen, aloysius, purehero, busted, etc.

I've been searching all over this forum as well as the internet on how people are using their HERO and the battery performance they're getting out of it. I've seen answers from 9 hrs with heavy usage to 36 hours with minimual usage. That's about all the detail I've been able to find. (Maybe I'm just not good at searching?)With that, I decided to do a little tracking of my own. I logged my usage and battery performance over a 27 hour period and thought I'd share it with the community. Not sure if this is even helpful but maybe it'll provide some sort of baseline for others to compare against.I recorded the battery level in % based on the stock battery meter, the time I recorded the battery level and any activity that occured between the current time and the previous time recording. For example, between 7:00AM and 10:19AM the battery dropped by 10% and I had received 2 emails, 2 calendar reminders went off and I had surfed the web for about 10 minutes.

So I changed my DPI setting to 150 since in launcher pro I use 5 rows instead of 4 so it doesn't overlap etc. And wanted to ask if changing the DPI setting may affect the battery usage (recalculating screen) or CPU (making it slower) or the games will lag? etc.
Changed it back, I think was lagging and the text boxes were smaller not on the whole page. And the confirmations had green lines in the middle.
How I did it:
1. Root Explorer , mount R/W in system
2. Open in text editor.
3. Edit the build.prop line with ro.sf.lcd_density=150 and save the file
4. mount R/O and reboot
Still if someone knows something about the battery usage and cpu etc. So I know in future if I should play around with this one.

Ever since I installed the Android 2.1 update I have noticed a significant increase in my battery depletion when I am using the camera app. This is even if I am using the camera app for a very short period of time. For example, I might take three or four shots in the course of two minutes and my battery drain would be on the order of 7% - 8%. This is way more battery drain from the camera app than I ever witnessed when I was using it with Android 1.5.
I also noticed on the battery status screen, where you can see how much percentage of your total battery life that various apps and system processes are using, that the camera app skyrockets up to over 90% of the total usage every time I use it for a few minutes.

I unplugged my phone from the wall charger at 6:30 am this morning. It is now 1:00pm and my battery is at 20%!!! It says that the display has used 33% and the android system has used 24%. For some reason it says that the calendar has used 14%, and I barely looked at it today. I installed bugless beast 7.5 last night, set the overclock to 800, and charged it up. Today, when my battery dipped to 40%, I went to setCPU and set the speed back down to 550. Still, now it's at 20%.

What have you OC'ers found? Is the extra "oomf" costing you much in battery life? And, can you easily make it through a whole day without recharging?

I've read a lot of posts about battery conditioning to get the most out of your phone and now since I rooted my phone and overclocked it and tend to change my cpu speed through out the day so I was wondering how this affects the battery life and if I should recondition the battery

After setting the overclock widget to reduce the CPU when my screen is off I find the mp3 player distorts the music when I listen. I have had to increase the screen off min speed to 480000 to stop this happening. This of course means I'm not getting the battery saving bonus that setting to 112, 160 or 245 would give me. Does anyone know a better way to set the overclock widget to give me the battery saving effects without distorting music? Or perhaps an mp3 player that uses less CPU? I'm running SenseHero 2.1 b4 and using the stock HTC music player.

I finally received my Sprint Hero yesterday and have been using the hell out of it since. Today, I rooted and installed Fresh 2.3.3 and I'm loving it so far - in fact, I'm using wireless tether right now, as where I'm at, I have no internet yet. The thing is, I'm wondering how to overclock now. I've been attempting to read-up on it and it sounds a little complicated, almost as though I need to rewipe my phone and set everything up again. Is this the case?
Looking at this, I've been trying to decipher it:
[KERNEL][7/22/10]Darchstar's Overclocked Undervolted kernel for senseUI roms vUV 2 - xda-developers
What exactly is a module remover and why do I need to do it? Moreover, I didn't see an option to flash a new kernel (maybe I just wasn't paying attention) when I was in the RA or whatever it's called. I'd love to get my Hero running a little bit quicker. Otherwise, I'm loving the thing so far.

I've been fiddling around with my Hero for a while and tried a few different things including Autokiller which is an alright program but didn't provide much noticeable difference to the performance of my phone. I've just been fiddling around with overclocking aswell. The reason I decided to try overclocking was because I bought Snesoid and the games were really laggy even with the sound disabled, even on more basic games like super Mario. I've tried overclocking to roughly 650, the 690 then 710 with not a lot of difference when using snesoid and with the phone in general tbh. I'm wondering if it's something else causing the phone to be laggy even after trying numerous things, could it be sense?
I've got systempanel lite aswell and it mainly shows these as the active apps:
HTC Sense 23.2M
Messages - 8.2M
People - 10.6M
Swype 11.6M
And these as Inactive (Cached) Apps:
My Uploads - 7.9M
Settings - 8.1M
Anyone got any ideas why it's still a bit laggy and very laggy with snesoid, I'm running VillainRom12 aswell btw.

I have been disturbed by how much battery it seems to use while it's sleeping. After much poking around and reading and using various system/battery/monitor apps in a non-methodical manner, I think I found it. I noticed that a process called 'compass' at /system/bin/akmd was persistent in utilization on my phone. While it only ever showed like 1-6% cpu utilization, it seemed to be showing it constantly. I uninstalled a 'compass' app I had DL'd from the market, but that had no effect.
With some searching, I found some threads over at XDA that discussed this process misbehaving in some recent builds, although the conversations didn't seem to be about the EVO. Nonetheless, I decided to disable the auto screen orientation (Menu -> Settings -> Sound & Display -> Display Settings/Orientation = unchecked) and lo and behold, I'm not sure the phone even uses battery in standby now! (exageration for effect...)
Now, this will require more testing, but it seems to be at the root of *my* battery issues. And I'm thinking after reading at XDA that this could be a broad problem. I'm also hopeful though, that this could be a relatively easy software fix for HTC/Google. Especially because I don't particularly find disabling the screen rotating an acceptable long term solution... but one I can live with for now, if it makes the HUGE battery gains it seems like it might.

this thread directed at those that did not root or unlock their HTC desire but uses its original android.. before i go on, my standard usage is as follows, mostly sms using, a phone call or two, less than an hour of wifi browsing at night.. on android 2.1, my battery lasted roughly 2 days and a bit more.. after updating to android 2.2 via wifi through auto update on the phone. today was my third day after charging my phone to 100%.
its now almost 5pm, on my third day and my battery still has a whopping 40% of battery life left.. so just wondering whether anyone else have this miraculous boost of battery life with android 2.2 or not.

I'm wondering what the best charging strategy is to get the battery working at its best. Let it run down to almost empty then fully charge each time or just keep topping it up when I'm near power?

I was screwing around with battery usage today and here is what I found as the bottom line. Now this doesn't mean this is the same for you, but I'm sure you all know that. I changed nothing on the evo besides Gtalk automatically signing me in. (No skimping if you would) and I was at a golf club all day yesterday and had perfect signal strength. My EVO went 23hrs on one charge with decently heavy use. When I went back home (bad signal, 1 bar, no 3G) my phone's battery lasted just about 13hrs. Therefore I think TWS is one of the biggest battery culprits. Hence why if you complain to Sprint, they send you a free Air Ave like they did for me and many others.

I decided to do a little test with my Evo. Yesterday my battery drained out in 3 hrs at work with the Wifi off. Today I turned on my wifi at work and I got 7 hrs before recharging the battery. Weird I thought if Wifi is on it would drain the battery faster.

I am using the Y5 app and my phone connects to my router when I am home. I just checked the battery usage and Wifi was showing 22%. My up time is right around 27 hours. Does 22% sound a little high or is that good?

What is the best way to determine what is using my battery? I know I can go to Settings | About phone | Battery | Battery Use and see usage to a certain extent. But what if I want something more granular? Usually, the largest percentage of usage is by the Android System, is there a way to see which components may be using the most?

Is there any device (phone or tablet) running Android 4.0.x that can display the native battery usage data via Settings --> Battery , instead of displaying "Battery usage data not available" ?
It is supposed to display a list of apps and what % of the battery they consumed.

I propose that we all post our battery life graph like the one I am about to post below. This way we can look at these claims in scrutiny, and perhaps figure out why it is that some people's Evos seem to last longer than others. Here is a graph of my Evo's Battery Charge over 1 day:
Wake up at 7:30am to disconnect the charger, listen to Pandora on the car to work until I arrive at 8am. Idles until lunch time at 12pm. Use the Evo to read up on some news at lunch until 1:30pm. Listen to Pandora while working until 5pm. Drive home while listening to Pandora in the car. Battery starts giving warning indications while driving, and phone dies when I get home at 6pm. Very usual day, and matches what the battery charge graph shows. The top apps of the day are:
System Processes contains mediaserver (2.4% due to Pandora), akmd (0.3% accelerometer polling), and everything else is <0.1%. As you can see I barely used my phone during the day for anything but Pandora. So based on my data, I'd say that the normal battery life for the Evo is under 10 hours. My settings are: no 4g, no wifi, no bluetooth, yes gps, yes bckgrnd data, auto brightness, no live wallpaper, yes taskmanager (ATK, set to "safe" setting. Will probably get rid of this..), no friend stream, no flickr.
I'd love to see other people post up their Battery Usage graphs as well. The App used is "SystemPanel App / Task Manager", available for free in the market. Go into Settings and allow it to Monitor. The screenshots were made by ShootMe, also available in the market.
