Dear Nexus One users!
I'm trying to gather some data for the following thread: http://forum.xda-developers.com/showthread.php?t=753382
I have a feeling that HTC has tampered with the Desire's power usage statistics in order to make the AMOLED screen seem more efficient.
As far as I've heard (only asked two Nexus One owners so far), the Nexus's display usage is about on par with the Desire's vanilla ROMs, which leaves me to believe that the vanilla ROMs are accurate, and the HTC Sense ROMs are the ones with the problem.
I hope you can help me gather some stats
Thanks in advance!
-edit- Forgot to say: The statistics I'm talking about can be found in Settings=>About Phone=>Battery Use, and I'm interested in the statistics after a day of reasonable to heavy use (web browsing, messaging, phone calls etc.).
It's usually in the 61-80% range even with heavy use. I have to admit that I run the screen on full brightness all the time though, so that can skew the results a little.
Thanks for all the votes so far guys!
Looks like I was right
Getting some good data here... keep it up, thanks!
just thought i would add... (hopefully not too off topic) the HTC Desire (the new SLCD models), the Display only uses like <10%, seems they weren't lying about the battery saving part (this is based on what I've seen on my friend's Desire)
anyways my AMOLED Nexus one is in the 60-70% range and I'm usually in Automatic brightness mode

Don't allow yourself to be fooled - AMOLED Desires also often use less than 10% of the battery according to HTC ROMs... which is precisely why I think it's bull****.
Hell, the day before yesterday I kept my display on nearly the whole day, just to test the new power consumption stats (using OpenDesire, and as of 3.1.0 the power consumption statistics have been changed to give pretty much the same results as Sense ROMs) - result: about 10 hours of total battery life (from a full charge!), 6 of which had the display running. Now guess what the new Sense-style battery consumption measurements told me? Supposedly, even though my display had been on all day, it only used 13% of the total battery.
So don't worry - I don't think it's true that your phone uses so much more power - but rather, that HTC has somehow screwed up the power consumption statistics in their Sense ROMs, and the screen is using much more power than they're showing.
And you're not off topic at all. You're a perfect example for someone confused by the discrepancies in power usage statistics. They're not logical, and they're leading you to believe that your AMOLED diplay is using a lot more power than the new sLCD displays in Desires, as well as the AMOLED displays in the older Desires.
My display is always up around 80% of my total use. Everyday its like that. And that's the way it should be unless your device sleeps all day with no use.
When doing your comparison, you also need to post your display-on time, and your total time since unplugged. These are in the same place as your percentages. This way we know the ratio that The display was used and how long the device was unplugged. Otherwise I could post a number but without a reference point its meaningless. What if my screen never turned on once? That certainly skews the result.

Theoretically you're right of course. However, so far the discrepancies are so immense that I don't think that's even necessary. Leaving the display on 100% of the time on a Sense ROM doesn't even allow you to crack 20% battery used by the display... Using the display for an hour on the Nexus or an AOSP Desire ROM, gives you at least 40% battery used by the display at the end of the day. Unless someone really keeps their phone off the ENTIRE time, I don't think the clarification is even necessary...
Hello everyone!
Thanks for the useful data. After continued testing by myself and a few other interested people (namely th3, who provided the idea for disproval of HTC's Sense battery use statistics once and for all, and Andycted, who has been providing many useful statistics which helped us get a better idea of general power consumption on the Desire), I've entered the issue on the Android Issues tracker.
You can view the issue here, and feel free to comment and/or star the issue to show your support, as it concerns all Android users. The problem may only be present on HTC Sense, but how will you know if future devices are reporting battery usage correctly if the statistics are so easily tampered with?
Thank you again for your help, support, and very helpful and constructive criticism.
Mine is always between 45 and 55 %, nearly stock FRF91 and minimum brightness
Haha, a friend of mine that just got the SLCD Desire was claiming his screen wasn't burning through the power like my n1 seems to. I guess it's unfortunate that it isn't the case.
I'd wager the SLCD really does use a lot less power when displaying bright colors, especially like white web page backgrounds... but even if your buddy spends his whole day looking at bright web pages (nothing with dark backgrounds), the battery usage of his display should be at the most 10% lower than yours

I totally read your post wrong, sorry.
We have figures for the approximate power drain of the AMOLED screen (155mA black, 485mA white) so where are the figures for the SLCD?

Back a few years ago (th3 posted a PDF from a company that manufactures AMOLED screens), the figures were around 200-250mW for the LCD (on all screen colors), while an AMOLED of the same size drew 700-something mW on a white screen. Obviously older screens, and smaller in size, but should be comparable...
I'll see if I can dig it up again...
Here it is:
http://data.4dsystems.com.au/downloads/micro-OLED/Docs/4D_AMOLED_Presentation.pdf
we need to get some desire users with the SLCD screen to install the current power draw widget to their homescreen and give us some numbers. or just pull them from the dmesg log. at this point i have pretty good numbers for the nexus amoled screen, and like said above black typically around 140 mA and white 350 mA, but those both a lot of the time go much lower and higher, respectively.

Nah, it's just that Sense uses more battery, therefore the screen doesn't use as much in comparison
I have tried everything. Stock, Franco and Lean Kernel, UVing by 25 as well as 50mhz, have greenified everything I can that I don't need. But I just can't seem to get more than 2 hours of SOT out of this phone.
i'm not really the kind of person prepared to shut everything(bluetooth, data, location etc) off to save battery. I bought a smartphone so I want it to be smart.
Some screenshots: first two are on leankernel, the last one is from an attempt today with franco right after I finished charging it up(phone barely held a day)

turn off adaptive brightness, and lower your brightness to 20% or lower. i keep mine at about 15%, and see about 5.5h sot. for every 20% i raise my brightness, i get 1h sot less.

That's why google did a bad job to deliver apps with a light material design on devices with an amoled screen.
Good apps does not have grey fonts on a white background. Or have options to change those colors.

5.5 hours of actual screen-on-time isn't horrible. I usually get around 4h but I don't care about stuff like turning down brightness or disabling bluetooth. My N6 easily lasts through the whole day - sometimes 1.5 days (with only light use, though). And if the battery (for whatever reason) gets close to zero Moto provided us with a gift called turbo charger...
It looks to me like you have pretty bad signal with the 69% with no signal. Your phone will keep searching for a network which is going to destroy your battery. Since you have WiFi constantly connected try turning of mobile data and see if that helps.

no. 5.5 hours of screen on time is normally considered very good.
Don't you guys swap in the Team Blackout inverted apps? It adds about 30-40% more screen on time on AMOLED screens. It won't help in areas like settings etc if you are stock based but they have all of the Google apps, Spotify, Netflix, etc inverted and transparent. It always gave me great screen on time on my AMOLED devices. When people asked about my numbers, that was my first suggestion.

i use layers, which is a new light weight open source theme engine. no cm involved! it was started by sony, then some devs here with a n6, took over. i use the pich black or out space layers. pich black themes the rom black, and also themes the gapps black, as well as the google launcher

i dont know if it works with stock to be honest, but im using terminus rom. here is the link to the layers manager app https://play.google.com/store/apps/details?id=com.lovejoy777.rroandlayersmanager tou can download layers themes here on xda, in the play store, and on g+
So I am currently on 5.1.1 rooted with Franco kernel. Before updating to 5.1.1 I had 3h and 44 mins SOT and still 16% battery left. I read that flashing Franco kernel will help my battery but I am currently on 55% battery with 1h and 40 min of SOT. I have greenifyed all the battery draining apps like Facebook etc and I don't have any widgets expect Google keep. I have attached couple of pictures if someone could please look through them? I did several factory resets and still the same battery life. I am just browsing and watching YouTube videos. Now I only get 3hrs and 15 minutes before my phones dies
It's driving me nuts, I read that Franco kernel will help my battery life but it's still the same. I have around 40-50% screen brightness.
Have you done any modifications to your CPU or anything like that?
Profiles/governors etc.

No nothing. Just flashed Franco kernel free app so I can't adjust any governor
regardless what you were told, flashing kernels does not help battery. its your use and the quality of your signal that will determine your battery life. kernels might help you in saving battery, because they all change how the CPU works, but its up to you to save battery, not the kernel.

Yeah I read that you'll get better battery life with Franco but I don't know. Is there something unusual from my screenshots? Is there anything I can do? I mean I am using my phone as normal as possible and I even turned of lte and running only on 3g. I just want to know what the culprit is. I even removed viber but it's still the same issue

what percent brightness do you use? I keep mine at about 0-10% mostly, and average around 5.5h sot. if I raise my brightness to about 30-35%, I lose about an hour of sot. but really, its all about what you are doing with your phone. if you are a heavy gamer, you'll see much less sot because CPU intensive games will go through the battery quickly.
Your best shot is getting the full version of FK app and then controlling your CPU.

actually, 0-10% isn't that dark. if you set adaptive brighrnes, 0-10% will actually be darker. 0-10% is fine for me, unless out in the sun. but with 50% brightness, I'd say 3.5h sot is actually fine.

Really? I have 50% on all of my phones. I'll try 10% and see. Is activating the adaptive brightness good for battery life?
Just want to know really if my apps and system is behaving correctly. If it's the brightness that is the issue then it's a relief. But I read that everyone got better battery life with 5.1.1 except me :-/ I mean I have Bluetooth off, gps off, hepatic feedback and sounds etc all are off. Even Google now is off

no, adaptive brightness is bad for battery life.
and for the majority, battery life is exactly the same on 5.1.1, like before. as many people that claim better battery life, just as many, if not more, will say its the same, or worse.

Of course that it would help. I got 7h SOT with my old S3 running a custom kernel. But after all.. Try it out yourself
Yeah that might be hit or miss with every update. But I still feel like one should get better SOT even with like 40-50% screen brightness, I have all the big battery hogs turned off like GPS etc

first off, paying for the full app will give you what, more control of your CPU? do you know how to control tour CPU? if so, there are many FREE CPU control apps. learn what you are doing first, then buy the app. secondly, no one that uses 50% brightness gets great battery life. the screen uses the most battery, raising brightness to 50% will just let it use MORE battery.

OK thanks mate, ill lurk around the forum and see what can be done :good:
Hi guys
I'm not discovering the fire but I want to make a little contribution for those who has bad sot (I was really annoying for me because I can understand the upsets users ones), this was my discoveries:
The first one and most important:
It seems that the phone is programmed for a certain time of use, I mean it has a maximum time for sot: 6 - 9 hrs so you have to use that time to spend it on screen time because the phone also uses the battery for other stuffs. So if you pretend to get 6 hours or more in more than 1 day you will become mad and taking the phone and throwing it throw the window.
The second one:
Continuing with the last point doesn't matter if you try to save battery reducing resolution or stuffs like that. I use every day performance mode at max resolution and sound quality. The important thing is manage very well the brightness so disable the 10%extra from performance mode. Actually I could reach 6 hours at 1% with a intensive use with wify, data, gps and stuff like that.
The third one:
It is unuseful try to disable things and apps from the phone, they are not important on battery usage except for brightness and (at least for me) AOD. This one drains my battery and I really don't know what to do with this so it is disabled for me.
And the fourth and last one:
It seems that the battery needs a intensive usage in order to get it max potential. Some days ago I use the phone heavily charging it with the dex dock and using the interface and I noticed before that the battery expand it life.
Well, I'm testing if a dark theme is useful or not in order to get better sot but mean while I'm pretty happy with the battery life (40 days of usage); at beginning was very upset with this.
Hope to be useful for anyone.
Cheers and my best regards and thankfulness for the help of the community.
Thanks man

I feel dark mode is eating more battery then light mode now.
I changed to light and getting around 5 - 6 hours SOT now with full on 120htz, 5g, wqhd , Bluetooth and stuff.
Location permissions are normally the culprits.
I also have smart tag and stuff.
2 years On I am still happy with it although I used to get 7-9 hours SOT before.
I try change myself and yes dark mode eat more battery then light mode.
Before update to android 13 i had a good battery life on my device now it's terrible...
Samsung don't fix it so we have to live with it or root the device..
