So just inherited my dads OG Droid. Currently rooted and runs Steel Droid (Mod Version 9000) and 2.6.32.9_RZ Kernel.
Phone is overclocked to 1GHz (125/1000 ONDEMAND).
Like the title says, the phone gets about 5 hours and then hit's 5% and keeps asking me to charge. If I charge it overnight and unplug it when it's 100%, it'll hit 90% idling (while I sleep) about 3 hours later.
Running Programs:
DSPManager
Words Free
Facebook
3D Digital Weather Cloc
News & Weather
3G Watchdog
Videos
SoundHound
Pandora
Temp+CPU V2
Now out of all the running apps, Pandora, Soundhound, News & Weather, 3G Watchdog, Temp+CPU, 3D Digital Clock are all widgets. Temp+CPU and 3D Digital clock are the only ones that actually run, the rest are just there in case I want to use them.
These stats today are from using Pandora for about an hour over Wifi.
Any ideas? Phone runs fine most of the time but I have seen the occasional lag where you have to click something 10 times before it opens.
I used to have a pretty big problem with battery life too, but even though I think they are somewhat silly and annoying the Easy Battery Saver app helped me quite a bit.
Wifi and using the speakers are heavy on battery life. Not sure how much difference it will make but try consolidating your widgets and app shortcuts to as few screens as possible.
Also your CPU governor might be set to something that lets the phone hog through anything at the sacrifice of battery. When i set my CPU to Performance my phone runs like a boss, while setting it to battery saver I get a little more lag but more battery, obviously. Not sure how/if your ROM will let you change that but it's something to look into.
I got it set to On Demand which might be the issue. The kernel is a low voltage kernel. How do ultra low voltage kernels run?
I did a battery calibration, downloaded Advanced Task Killer (Battery saver didn't work well, I'd always have an issue with 3G not activating) and got rid of all my widgets. Currently charging it up completely, I'll check it out tomorrow.
So the title is incorrect, it says 5 hours and 5% left. I checked the battery info at 5%. It said 4hr 4x min. About 10 minutes later it shut off so I didn't even get 5 hours to a full charge.
I don't have high expectations but coming from an Alias 2 that had the extended battery (I'd get a week of battery with my use), this is pretty disappointing.
Well I can tell you now, ondemand is NOT good for battery, what that governor does is make it so the CPU will go from MIN to MAX speed slots depending on what the phone needs, AFAIK it doesn't scale with need, it just goes to max. So your phones CPU was running at max most the time which kills battery.
Can't say anything about your ROM, but I use simply stunning 5.6 http://www.droidforums.net/forum/chevyno1/177728-ss-5-6-2-3-7-incl-1-battery-other-goodies.html Which, with his low voltage 1ghz kernel set to the smartass governor, I get anywhere from 8-14 hours of battery life depending on use. Using ultra low voltage kernels depend on your phone, some phones have trouble overclocking to 800mhz mid-voltage (mid-voltage is considered to be the most stable, but use the most battery), others can overclock to 1.25ghz ultra-low voltage, which is very rare. I would say try out all the different voltage kernels and see which one works best with your phone.
Also task killer = MAJOR MAJOR No no! The task killer will kill the apps, and the android OS will restart them, using more CPU time and making the battery actually not last as long, I would recommend learning how to use the supercharger script http://forum.xda-developers.com/showthread.php?t=991276
Can't say much about the majority of programs you have running, but I've found facebook does not like to play nice with the Droid, also, why use the 3D clock when the Droid comes with a built in-clock app? Pandora uses a lot of battery, so running it w/ the ondemand governor is probably what hurt your battery there.
Not many Droid users left out there, but I was and still am an extremely avid Droid user, so if you have any more questions just shoot me a PM and I'll help as much as I can.
Thanks! I got rid of all my widgets and installed Chevy's ultra low voltage 1.1GHz kernel on smartass. I lost 20% battery pretty fast but let's see how long it runs. I've had no force close issues so far. I'm a bit tempted to go to 1.2GHz ulv.
How much does the ROM have to do with battery life? I really love this ROM and it's interface. I thought the battery life really only had to do with kernels.
I also got rid of the clock widget and put a default clock widget. What's the built in Android one? Is that the "Analog Clock"?
Sorry for all these questions, I'm pretty new to Android. Only had this for 2 days (~8-10 recharges...)
Its fine, better to question and learn then to just get mad and over it, and Roms have everything to do with battery, they are just like kernels, some work AMAZING on some phones, while others can destroy battery life.
Like my rom, I found the perfect one for my phone, I get 8- (been thinking about it more) 20 hours of battery life on mine and it has pretty amazing performance too with the occasional hiccup.
And I thought you had the clock app installed for an alarm, not for a widget, my bad. I don't use a clock widget so I wouldn't know.. Also, I've found its not very good to run many widgets on the Droid, as it has limited memory and can only handle so much.
Well I got sick of it and reflashed the entire ROM. CPU governer is set to ONDEMAND 125/1000. Only*widgets I have are a simple clock (like the iPhone lock screen) and power control. Gonna see how it goes. So far so good but I'm saying that because I didn't loose 20% overnight. If I can clear the day, I'm good.
googlelover, what CPU Governer did you find to work the best with your phone?
I have been an Android owner for a while now, with the Droid being my first. Until recently battery life had always been an issue for me. Undervolting has never had an effect over a 20% improvement. And this is only when it's in deep sleep. Otherwise, in very general terms, undervolting can require a higher current aka worse battery life if you use your phone a lot. With undervolting comes the risk of data corruption in your phones memory and SD Card. What really kills your phone is screen on time, wakelocks, CPU overclock, and signal quality.
The last you have no control of. But if you're overclocking 1GHz or higher you have to realize that's almost twice the manufactured clock speed. As far as wakelocks, this is when something keeps your phone from going into a low power state. This can happen because of a rogue app, a buggy ROM, or having too many widgets. I ran into a ROM a while ago on my Fascinate that would stay awake if you had GPS enabled. The best you can do with your display power usage is to keep your brightness down. Hope this explains a few things
have the same issue

I already told you, the smartass governor, and like I said before, ondemand is not a good governor in my opinion. There are way to many factors in battery life to have anyone else be able to truly help you with it, all our phones are different and it really just takes time switching kernels, switching ROMs, etc to find what works with your phone
Sorry googlelover, I forgot you already said that.
So update guys. I've been going a day (so like 18 hours) of use after which it finally hits the 15% warning.
What I did:
Basically I reflashed the ROM and started from scratch. Before reflashing, I wiped the user data/cache/davick cache etc at least twice just to make sure it was really wiped.
I reflashed SteelDroid 9.0 with the default chevyno1 lv 1ghz kernel and gave it a go with just a simple clock widget. Worked well. One by one, I'm starting to install applications until I can figure out what was draining the battery fast. So far, so good. If I can get 18 hours on a 2 year old battery, I'm going to be doing fine with my extended battery.
One thing I did notice was that the phone back by the camera (where CPU is) isn't getting as hot as it used to. Makes me think that the phone was at a high clock speed in sleep. Another issue may have been my CPU temp/speed monitor. It was probably poling the CPU stats every second which made the phone increase the CPU speed because it sensed activity.
Try out the ROM I'm using. I absolutely love it. The interface is phenomenal and it runs very well.

(remove the spaces to see it, I wasn't able to post links normally because I don't have enough overall posts).
There's probably other ROMS that run better like the one googlelover is using, but I can't use the default Android interface anymore after using this.

Don't forget not many roms have the default android interface, many have themes to completely change the look, if your happy where your phone is, great! But if you ever feel like your phone is slowing down again, I'd still recommend looking around and flashing some different roms.
Thanks, I'll keep that in mind. I'm only using this phone for another couple months. I'll be getting the Droid 4 when it comes out. Looks like a really nice phone.
I've noticed that when the battery gets below 35%, many games start lagging. I couldn't figure out what was causing this so I had a hunch that the OS is forcing the cpu to under clock even under heavy use to conserve battery. I installed setcpu and forced the cpu to max and sure enough, the games were playing smooth and home screen transitions were smooth. I did this a few times just to confirm. So is this true? Does the stock OS force the cpu to under clock even under heavy use when the battery is low?
And just to clarify, I'm not talking about cpu throttling. I understand android devices throttle the cpu based on use.

setCPU?
It does exactly that. Make a profile for Battery < 35 and set it to your clock speed.
Sent from my Samsung Galaxy S II w/ CM9
Updated section:
After clearing cache through recovery and doing a hard reset, the uAh has gone back to 3142000. Standby time seems good with the battery losing 7% overnight. It does charge quite quickly from 0-100 in about 2h. The previous heating issue remains with cpu monitors showing that the cpu jumps to high clock when I touch the screen. I don't see any change in which apps use the most battery with the screen taking up the most as before the problem started.
The heat appears to be what is draining the battery but I can't find any single app that causes it to ramp to max.
Pictures:
No-frills is set to stock settings to see how the phone handles the actions
2nd picture is when phone is idle
3rd picture is immediately after swiping through a few tabs and scrolling through some pages in the app which causes cpu clock and load to increase
Old sectionFor when battery uAh was low)
I've had this Z1 for about 11 months. I can only get around 2.5h on screen time with regular usage. The battery uAh was only 1848000 Recently it fell to the 1700s. Calibration appears to reduce the value further. The phone seems to heat up in about a minute or two no matter what app is running.
The phone is rooted on stock 4.4.2
I have tried updating to Lollipop before but received an error due to rooting, so I don't think anything changed.

sounds like it's time for you to replace your battery.
You may try to disable the "input boost frequency"
By default when you toch the screen, cpu frequency of two cores instantly jumps to around 1400 to preventing any lag but it seems to use more power and causing heat
I have disables this and since then I'm no longer have any heat issue and also the battery life is so much better now but you may exprience a little lag while scrolling on heavy web pages but thats all
Btw i'm on .157 and using Kernel Adiutor for cpu tweaks
You may disable this by the app mentioned above or by editing sys.somc.touch_perf_kick=1 from 1 to 0 in buid.prop or adding this line
Why is performance throttling so aggressive with the P9? I live in a tropical country where the weather is very hot right now and my P9 can't seem to take the heat. After a few minutes of using GPU intensive apps like the PS1 emulator ePSXe, the currently loaded game (FFIX) lags terribly and switching apps considerably slows down. I've also noticed this throttling starts to take effect whenever my phone gets below 50%. This also happens on other games like SimCity where panning the map is horrendously slow, gets smooth after a few minutes but then lags afterwards.
Is there some way to at least tone down the throttling, or are we stuck with this? My previous phone was a G4 but it did not lagged nor throttled aggressively like the P9.
...or is there a custom ROM for the P9 yet? Cyanogen? Lineage? Or is there a way to 'downgrade' to Marshmallow? I think performance was a bit better before upgrading to 7.0
Thanks!
I'm on the B381 Nougat build, EVA-L19 model.
There was a thread here that explained that there was a thermal limit set around 50 degrees celsius and could be altered to have a higher thermal limit. You will have to search for it.
I have noticed the Xiaomi Mix has some persistent software thermal throttling after a short period of time.
I ran the same test on a OnePlus 3T and noticed this throttling issue is not present.
It's possible the temps to start throttling are too low on the Mix.
Is there any way to modify or increase these throttle limits?
I know this has been done before but I cannot load the Thermal conf file in /system/ etc / thermal-engine.conf
Can we replace the file with something else ?
The OnePlus forum members released several versions of the file with different throttling temps. Can we use these files or make our own.
https://forums.oneplus.net/threads/oneplus2-how-to-fix-thermal-throttling.417108/
Did you ever get any further with this? My phone idles at ~35C. I read a review that said throttling begins at ~40C so I get throttled when I do virtually anything.
I've only had this thing 2 days and the performance has been worse than my old Nexus 6 because the cores keep getting capped very low. I was copying some backed up files over WiFi from my PC. It was lots of small files so it was running for 20 mins or so. When I was trying to do other stuff in the meantime it started to get really sluggish. I used to do exactly the same thing on my N6 and I could never tell that file copying was running in the background. I checked Kernel Auditor and it was showing temps ~50C and the cores were all being capped around 5-600MHz.
I've tried the stock ROM (stable and beta) and EPIC, and Lineage/RR. It seems to be a bit worse on the latter two (Antutu won't go above 100k, but it's like 140k on the MIUI ones) for some reason, but it's an issue on all of them.

I have absolutely gotten further here I have managed to get throttling completely disabled actually.
The highest temp the CPU got to was 42 degrees Celsius after running Dolphin for 2 hours straight.
There is no need for thermal throttling on this device at all, hardware does a good enough job clearing the heat.
To stop the thermal throttling you need root access.
Use ES File Explorer from the play store and enable root access
Navigate to root and look for Folder system/etc and find file called thermal*******.*** ( I don't remember what it's called )
Cut this file from this location and paste it into another directory. I moved it to the sdcard for easy access. This way you can move it back if you do not like the results.
I have not experienced any overheating with this, also the battery doesn't drain like crazy. Performance is greatly improved with speed matching the Snapdragon 835 in a few scenarios.
Oh yeah restart the phone after you move the file so it can register the changes. Clock the cores appropriately with Kernal Auditor to make sure it can run at full blast when it needs to. On demand is way faster than interactive.
Cheers. I actually read the links you posted and renamed the conf file. After a reboot it was flying. The problem isn't so much the throttling, it's that mine idles at ~35C already, so it was getting capped when I did virtually anything. If I run Antutu 2-3 times in a row and check the temps in Kernel Auditor it can be in the low 60s. Using other temp apps (CPUTemp) it only shows about 45C tops.
It definitely does feel pretty damn warm since I don't use a case. but I'd love to know what the 'real' temp was. I tend to believe the lower one since I got the 45C warning when using EPIC and that's exactly what the app said. it was.
My Antutu scores increased substantially too. I was sometimes dipping down to 80-90k but I regularly get ~140k now, even 160k once. I know not to go by those scores but when I could never even get above 100k it was a concern.

Yeah I'm thinking Xiaomi severely limits the thermal threshold to improve battery performance.
It's kinda all they care about in Japan for some reason.
Makes for some great performance improvements without the thermal settings being active.
This setting change is almost necessary of you need some heavy work done.
Glad you were able to get this changed.
i remove thermal_8896_blabla.conf...
Honestly device become too hot for me.... backplate change during my game (Battle Bay), very different sensation... reinstall immediatly *.conf... Finally i have decent perf and cold phone and very good battery life... no more...
My opinion !

I think our best solution would be a modified .conf file that increases the thermal threshold as opposed to completely removing it.
Until this solution is available then this is our only choice.
i agree... i think with a ROM kitchen mayve this fil can be readable... anyway @ this point, we can only hope somebody dectypt this file to support various cool modification available over XDA...
Edit /
it seems HTC make same stuff... here it is a guideline ot example...

I had the same issue. I was getting 165k+ in Antutu but the phone would get uncomfortably warm when doing multiple passes, or gaming for extended periods.
In the Thermal section of Kernel Auditor, I enabled the Core Control and Temperature Throttle options and the phone still gets warm, but only as warm as you'd expect. I still get ~155k in Antutu consistently and the performance in general is still very smooth. I have the CPU governor set to ondemand, and the GPU governor to simple_ondemand. All other KA settings are default.
One other thing I always do is to reduce the Window Animation, Transition Animation and Animator duration scales to .5x (1x by default). It just makes the phone feel snappier in general. Settings > Additional settings > Developer options (MIUI-based).
I'm using the latest EPIC ROM. Using RR/LOS I couldn't replicate the same high Antutu scores consistently for some reason. I quite like MIUI after years of using CM and CM-like ROMS anyway.
already reduce animation x0.5... MIUI use a lot of this animation with complex and (very long calcul) then reduce this number make device seems much faster... anyway, u right...
A custom kernel for miui base... based on Dragon XIA exist in MI5 thread... only need to play a bit to make universal... with all source we can make somthing, but no have time to play with all tutorial available on XDA or Youtube...
Only way to make device much smoother and battery friendly or Perf/Warm destructor...
