I'm starting to see a correlation between absolute crap-for-crap batter life and having the ambient light detector enabled. I'll do a test tomorrow, but I'm pretty sure if I just left my screen on full brightness all day, that I wouldn't get as bad of battery life as I do with the ambient light detector turned on.
Is there a problem with the fascinate's polling period? or possibly how much power is being sent TO the sensor? This might explain the problems on hacked roms where people are noticing a buzzing/hissing noise coming from the phone right around the area of the ambient light sensor when in the middle of a call (and the screen is on).
Has anybody seen where in the code the ambient light sensor is handled? (is it in the kernel, or somewhere in the drivers?).
*EDIT*
Thanks for moving my post. I was pretty annoyed with myself for posting in the wrong section.
*edit* Now that the thread has been moved, This post could probably be deleted.
--------------
Well, since nobody has moved this to the other forum yet and it's received a few views, Has anybody else noticed this before?
My personal experience had been full brightness ate battery fast and low brightness was a combination of hard to read and similar drain to auto. Then again my phone has never hissed at me except for godawful noises using skype wifi sometimes, and I have never messed with brightness under froyo.
My only observation with froyo roms is that "stock" eb01 was awful but superclean and AOSP were pretty good, particularly under EB+ kernels.
Also, I lose more battery than I would like to from signal loss overnight, but turning off 3G seems to help with that.
Swyped grumpily from my advertised as "can be upgraded to Android 2.2" device.
i noticed that the automatic brightness setting is absolutely terrible at choosing the correct brightness.
the froyo roms added the ability to hold down on the status bar and move left and right to adjust the brightness, so i just use this to adjust it on the fly when necessary.
this doesn't really answer your question, but i figured i'd add my 2 cents

The noise comes from having the key backlights on during a call.
If you are referring to the softkeys, there were some assumptions that this was the case, but I have tested this out and have heard the noise even when those lights were turned off.
Also, I ran my phone at about half brightness today all day. I've had it off the charger for 15 hours, made 3 hours worth of phone calls, and it's still at 41% battery life.
2 days ago when I just had my phone in the pocket, not doing anything and leaving the screen off (with auto brightness enabled) my battery was dropping significantly after only 6 hours and no phone calls or Internet usage.
Hey all,
Having a few battery issues, hope someone can help.
1st issue is - i went from 100% charged to 70% in 1 hour. Yes i was using the phone the whole time but i was doing simple things like just setting up all my 7 home screens. Brightness is set all the way down to low (0), no auto brightness and i even have the dim screen setting on as well. I checked the battery usage and it said screen took up 50% of battery loss. Surely this isn't normal? I was only pretty much setting up my screens and settings, nothing intensive!
2nd issue is - I have noticed that even though the phone says it's charged to 100%, i have downloaded a few third party battery widgets/apps for confirmation and MOST/ALL says phone is still charging and not 100% even though the stock battery/phone says it is!
also battery circle and 2x battery when they finally reach 100% even though stock phone battery has reached 100% quiet sometime ago, as soon as i pull the power cord out it immediately drops to 99%.
WHAT'S GOING ON!
Any help?
=)
Thanks in advance!

The screen is the biggest user of power on any touch screen phone. It not only has the display but it also incorporates the touch portion as well. Using it 1 hr strait constantly and using touch that loss really isnt too bad. Just the display on by its self is bad but touching not only uses more juice but it also jumps up the CPU while touching.

Moto Phones report in 10% increments. It may show 100% even though its not. to fully charge turn the phone off and plug it back in. It should continue to charge. Look into something called bump charging. Essentially its just involves the user turning the phone on and off and plugging it in until it reads 100% immediately without charging.
also battery circle and 2x battery when they finally reach 100% even though stock phone battery has reached 100% quiet sometime ago, as soon as i pull the power cord out it immediately drops to 99%.
Another common thing with phones. I have had multiple phones that do this. Nothing to worry about. Its just how the system is reporting it. Its NOT a power loss or anything. Part of the issue is from what I am hearing is the lithium batteries are fully charge (100%) at a certain level which is only maintained while plugged in which is why it shows 99% immediately when unplugged.

we have 3g and that's about it.
if that saves juice then all the better!

Go settings - wireless and networks - mobile networks
U can choose ur 2g/3g settings there
Mine is XT910S from Korea.
I always dial *#*#4636#*#* and the phone will show an advanced menu where you can see the imei as well as choosing from a long drop down list of Mobile data settings.

You can turn it off under the network settings like others have stated. Turning off 4G here with our phones in the US can increase battery life significantly. 4G radio is #2 or #1 in the power drain depending on what you are doing.
I must say, with it being a AU version I am not sure if it even has the 4G radio inside, I would have to look into the GSM versions; or if someone with a non US phone could chime in and advise.
I personally just leave my 4G on all the time. I live in a great 4G area so the phone doesn't waste power searching for 4G signal. However when I download something 10mbps or more really does hit the battery hard if you do some big downloads or stream movies/music. I have no issues with charging it every day.
The time of charging your cell phone once or twice a week is gone.
I don't know if anyone has tried this yet, but after I have tested it for almost a full work day I can say it's definitely worth using..
Try this: After you completely charge your phone, turn on Power Saver (make sure all options are checked in settings)
Leave it on, don't turn it off, for the entire day.
I had absolutely no slow down.. no problem receiving timely texts/notifications.. the only thing that is a minor annoyance is that screen brightness stays low no matter what, so if you view your screen in full sunlight a lot this will not be for you.. otherwise, HOLY CRAP this makes your phone literally sip power all day.
9 hrs 21 mins 44 secs since I unplugged my phone this morning and I have 63% battery left!
That's roughly 3.96% battery drain per hour!!
This means I will get something like 24-25 hours before I hit zero.. this is with using the phone like normal, where I would normally need to charge after about 16 hours.
Insane. Best battery life I've ever had on a stock phone, and yes I know those monstrosities like the Note 2 can go longer (huge battery..) or if you want to tweak your phone with custom kernels, etc.
But daaaamn I have to say I am impressed.
Leaving Power Saver on from now on!
Btw I should add this is without Wi-Fi, in a LTE area that bounces from LTE to HSPA a lot.. WiFi left on but never connecting to a router

Update. Battery running down a little faster while on my home Wi-Fi watching videos and surfing the net. Don't think I'll make it 24 hours but I am using the phone pretty heavy. I've also noticed that the auto brightness seems to be working overtime whereas it never budged during the day. Tomorrow I'll set my brightness manually to stay at ~30% and turn off the screen option in power saver. See if that yields even better results. So far it appears auto brightness is a power consumer on this phone. We'll see if I'm right tomorrow. I'm at 23% at 14hrs 21mins
Sent from my HTC One using xda premium
I should add that normally I would have charged the phone by now for about two hours since I do most of my heavy usage at night, and when I get home from work I'm already at 20%. But when I've let it run down almost all the way it's been an average of about 15-16 hours
Sent from my HTC One using xda premium
OK so today I kept Power Saver on, but unchecked the "screen" option so that I the screen would adjust as normal to the ambient light conditions. I am finding that the power consumption is essentially the same, very minor change. I now believe that it is Wi-Fi that was causing a quicker drain than LTE/HSPA does, simply because Power Saver does not include an option to cut the Wi-Fi connection when the screen is off.
I will change my Wi-Fi settings to sleep when screen is off and see if that keeps the battery draining at the same slow pace when I am at home connected to my router. I'll try that tonight. If that works successfully, I should get an easy 20 hours + from one charge with normal use (including my evening usage which is heavier usage).
Last night I hit 18 hours and 22 minutes before plugging in at 12% remaining battery without changing the Wi-Fi sleep setting. Hopefully this will be the last test necessary to find the best set up for longer battery life.
Feel free to chime in if anyone else is testing this!
I haven't test the difference between Power Saving and normal. I put Power Saving On in the morning right after a full charge.
I have medium usage for about 20 minutes in the morning using wifi. (It would drop to about 94%). I then turn off wifi and mobile and by 1pm, I have about 82%-88%. I would have about 20 minute usage on mobile data during lunch (flux between 3g, H and rarely LTE). By the time I leave work, it's around 74%. This is when I turn off power saving since I'm usually heading home. Another 20 minutes of medium to heavy usage over H/LTE when on the subway. By the time I get home, it's around 70%. After this, it takes at least about an hour of heavy activity to drain it down to 50% off power saving.
I have the 64 GB Developer Edition and running ARHD 12.1 with the latest T-Mobile Radio.
I've always left power saver on at all times and don't notice any slowdown. One exception is that I don't enable power saver on the screen as it's damn near impossible to see the screen outside. I get pretty damn good battery life on stock rom. Over 3 hrs screen on time in 24 hr period of half mobile data and half wifi.
For enabling and disabling wifi automatically, I use the app wifi matic and it's worked well.

I can easily say the dim screen option is completely unnecessary. Everything is working perfectly, there's no slowdown whatsoever. Even set keep Wi-Fi awake to never. Phone flies, and honestly the data connectivity is ten times better with power saver on. Without it, I would see my phone jump to 2G in a moment of bad coverage and then take FOREVER to reconnect to LTE or HSPA. Now when I unlock my phone it's instantly connected, as if a radio refresh is instant on power saver but laggy as hell without it. I'm very pleased.

Just thinking out loud here...
I don't see how with the data connection off you could have "no problem receiving timely...notifications." What "notifications" are you talking about not missing? Are you saying you actually got cloud-service-based notifications while the phone was sleeping?
Texts/SMS of course would still come in because they don't travel over the data connection, they travel over the voice network.
Email, twitter, etc., they shouldn't get their notifications since that stuff travels over the data connection.
Google Voice users (like me), would miss out on their text messages since those travel over the data connection.
I'll need to test this some. Maybe with the data connection turned off via this setting, the phone actually periodically fires it up to check for notifications, or responds to apps requesting a quick data connection to pull notifications.
UPDATE: Hmmm...turned on power saver, turned on the data disconnect option, put phone to sleep by pressing power button. Waited a minute. Sent myself a google voice # text message and the phone buzzed immediately. Very curious.

I was confused about that same thing. I think it only turns off your data if you havent touched your phone in a while.
If I turn it off, put it down, and pick it up 5 mins later, the data is still connected.
If I turn it off and its in my pocket for an hour, I take it out, the data service is usually trying to reconnect.
I have to admit the way HTC implemented their power saver is impressive. It literally does not delay a single notification. Facebook, Gmail, Hangouts, Scramble with Friends, anything that is set up to notify me works without a hitch. Everything is instant.. compare this to "power saver" mode on the Galaxy line which pretty much cripples the phone.
There is NO reason whatsoever to not have Power Saver turned on with the HTC One. Best implementation ever.
I've had no delays even after not touching the phone for a solid hour. Still get them.

Okay, a little google search reveals the secret behind the data connection magic:
If you want to choose which phone features to conserve power for, tap the Power saver notification first before you turn power saver mode on.
Note: If Data connection is selected, HTC One X automatically disconnects from the mobile network after 15 minutes when it's in sleep mode and the data connection is idle (no download activity, streaming, or data usage). It reconnects and then disconnects periodically when the data connection is idle to save battery power.
This is from the HTC One X support site, but the same quote is on many of the devices, but oddly not our HTC One. I think it's safe to assume it's the same for our device, whether published or not.

My phone's been untouched for an hour or so, and I just sent it a Google Voice text message. Buzzed instantly, and in light of my above research, it looks like you're correct. I'm certainly going to run with this setting on for a day or two at least for further testing. I only have CPU and data enabled in the settings. My testing the next few days may not be the best, as I'll likely be on wi-fi most of the time, although I could turn wi-fi setting to disconnect wi-fi when sleeping.
I've been using that Qualcomm Snapdragon battery guru app, and Greenify on my phone, so it gets damned good battery all things considered anyways, and I also am not afraid to go on charger during the day, but every little bit helps.
Just a few comments on the power saver:
I've noticed that power saver doesn't disconnect the background data immediately... it does it after a longer interval of non-usage.
Otherwise, it's great. I'm not sure if it's the screen dimming or the underclocking, but it really makes a definite difference in the battery life. I also turn it on for a lot of games (cough, dead space) and it helps keep the phone cooler while gaming.

Not the screen dimming, because I don't use that option.

FYI, it underclocks the CPU so the max is about 1.2ghz; When using Faux Control App, I toggled the Power Saver from the notification and can see it go down to about 1.2 ghz when "On" and when switched off my CPU clock maxes out back to 2ghz.

Yeah I figure that would be the clock speed, but I haven't suffered any loss of performance which is amazing to me.

I can also concur to this fact; since day one of owning this phone I've had power saver on permanently set and I've never experienced performance issues like in other phones, its been smooth, and helpful. The amount of usage I submit my phone to in one day its enough to make any other phone live permanently connected to the charger, and I get at least 1.5 days of juice.
I agree, HTC did a good job with their power saver mode.

6 hrs 23 mins 3 secs since i unplugged it and still have 82% without using PowerSafer. switching between very low LTE and very good hspa all the time and i'm using it quiet often checking facebook, twitter, mails, whatsapp and news.
The only Powersaving App I installed is "Wifi-Matic" wich turns on Wifi only if i'm connected to a specific radio station. Check in to your wlan one time and it will safe the radio stations around. if you aren't connect to this stations it will disable Wifi by itself. Works great for me! (Checking radiostations every 15 mins).
This means for me loosing 2,889% every hour without dimming the screen or something else
Give it a try and compare

How about you try that, with power saver on as well, and report back?
Besides, if you're barely using your phone at all, then yes it will be saving power with sleep mode alone. All I know is I have several friends who move in and out of bad reception/data areas, and now their battery is lasting a whole heck of a lot longer using power saver. It sounds like what you're using is somewhat of a power saver as well.. but you are in a good coverage area too so it's hard to say.
Btw, my figures were with Wifi always on - never switched off, ever.. and I still had greatly extended battery life.
