So how much juice does HAPTIC VIBRATION actually use? - Vibrant General

Although I usually have this option turned off because of battery life concerns, how much of the batt juice does this option actually use? I know there is a setting to set the intensity to low. I would like to start using this option because.... because I like it.
Thanks!

haptic vibration is created by a tiny motor.
motors tend to draw a lot of power (compared to other electrical components).
so while haptic vibration is nice to have it will have a noticeable effect on your battery.
only way to tell for sure it to run your battery down without it on, then run your battery down with it on, and see what the difference is.

Lol, that is definitely not a way to tell, I doubt their person can properly create a perfect control group.
In short, the more stuff your phone does, the quicker you kill the battery. So almost every additional feature you add will affect your battery life negatively.

you don't need to have a perfect control group.
run the test a couple times, check the averages and compare them.
I'm guessing that what with haptic feedback on the results will be obvious.

I had shut mine off (which was in full intensity) yesterday afternoon to test this very thing. Will report results today.

If you like it, turn it on. Its for tactile feedback after all, and turning it off would be crippling the phone's functionality, leading to more typos and more frustration. Its a small vibration, not the ring+vibrate that makes your phone leap past the edge of a coffee table. If you are really dying for battery life, I highly doubt the haptic feedback is the culprit or be a gamechanger.

I'm fairly certain that haptic feedback drains a substantial portion of the battery juice. One of the first thing I did after a few days of playing around with it was to disable haptic feedback. I use the softkeys a lot and having the phone vibrate each time i press then surely can't be good for the power supply. nothing scientific, but just a strong, common-sensical hunch.

appreciate the answer guys. I guess it only makes sense to try it out. Thought it might not be super accurate, it should be fine I actually have very good battery life right now. Even playing an hour or two of games like homerun 3d and armored strike I can usually last for over 15-18 hours. Will post back with the results.

Under Settings>Sound and display>Vibration Intensity you can adjust how strong the haptic feedback is.

Ive always had Haptic feedback on all phones that had it, i like it i mean yeah im sure it does help drain the battery faster but i would just turn the Intensity down a little. oh and the haptic feedback doesn't effect the keyboards btw (guessing this all has to do with which keyboard you are running but im not sure)

Believe it or not, audio generated from the speaker actually consumes more power than haptic feedback or vibration from most devices. You won't really notice any significant battery gain from disabling haptic feedback on the Vibrant. Screen brightness and backlight duration, radio operation, and media sound consume the most power on your device.

At this point, I choose not to believe that. Servo motors love juice.

I'd just be curious if anyone would care to develop an app that could read hardware draw like we can on apps. I'd pay for that.

I dun use haptic also but if it helps to type more accurate.. Why not

Capacitive buttons / trackball light control?

So the one thing that is annoying me a lot about my Nexus One is the backlight on the 4 capacitive buttons and the trackball flashing at night when it sites on my nightstand. I guess I could also add the charge light to this case as well. But that is less bothersome at the moment.
Does anyone have anymore information on whether the light for the trackball, capacitive buttons, and charge light can be disabled?
The only bits of information I can find searching is that the phone needs to be rooted to do this. That is great. What would be the next step? Is there a /proc listing for the trackball, capacitive buttons light, charge light that might take input to disable them?
Would love to hear if anyone has more information on this subject as i can't seem to find much info.
I have the same problem because I either have mine on the bed with me or on the night stand and that damn track ball light is bright when its pitch black, and I can't even tell you how many times I've bumped those damn capacitive buttons while typing or just in an app.
I hope the guys building custom roms will add toggles, or some developer will make toggles for rooted phones that would be very awesome and appreciated, I don't think just by me either.
I've never seen mine flash while charging, maybe if you have an alert, but you can clear those before you plop your phone down for the night.
the only light i have on when charging is the little orange light....
I'm guessing, that you need to answer a message or email or something.
You can use LEDs Hack, from the Market, to disable them; you can even configure it to automatically disable them when you plug in your phone, and re-enable them when you un-plug. It's free, from the developer who created Bedside, the (IMHO) best night clock app. (If you like LEDs Hack, you might try Bedside for a mere $1.50 -- a pittance, really.)
My impression is that if you have the built in clock application running before you turn your phone off, trackball and buttons light won't turn on even if you have an alert. I might be wrong though...

LEDs Hack looks EXACTLY what I am looking for. Thank you for this tip (doesn't show up in my searches. But found on androlib.com).
IMHO, this functionality SHOULD be native in the phone.
I wonder if this program also covers the trackball light flashing?
Yes, I know the flashing is because I have a message waiting. But the point is, I don't want to be woken up in the middle of the night because of a flashing light just for a silly email or text message!

Decrease haptic feedback?

Is there a way to lessen the amount of haptic feedback? I like it, but I've used some apps that don't vibrate as much as the default and it feels much nicer, more fluid. I'd like to know if it's possible to adjust the amount of feedback (rather than just turn it off).
this would be useful. i tend to turn off haptic feedback but if it were a little less 'intense' maybe i'd use it in some apps
The Quickdesk app has a near perfect use of it imo...it's more a subdued 'thump' than multiple vibrations. It feels very natural and 'just right'.

Nexus S in call volume

Has anyone else noticed the in call volume being very loud even when on the lowest setting. Mine is super high, any suggestions to resolve?
Sent from my Nexus S using XDA App
Yes, I'm having the same problem. But it don't seems to be a problem every time. Neither seems it to be connected to specific callee's. Sometimes the volume is totaly normal, and sometimes it feels like speaker mode...
Mine is everytime though, it really is too loud even on the lowest setting.

You are lucky, actually. I have exactly opposite problem. My volume of calls is so low that I cant her the other callers. This is very serious issue for me and I am thinking about returning the phone. I am searching the net for some service codes that would allow me to raise the internal volume. Do you have 2.3.1?

T-Mobile's or Google Voice? I have no problems with Google Voice and make sure it's set to come out of the speaker. I haven't used T-Mobile's in a long time.
[Q] volume & screen
After climbing (for me) a steep learning curve I am very happy with my NS. But as with anything, there are different levels of happiness. I still have two issues that sort of bug me.
1. Volume - It seems that I must accidentally hit it a lot, and at times find it turned all the way down.
2. Screen - It's amazing inside, but when I go outside in this Florida Sun (even in the winter) I not only can't read the screen, I can't find the buttons on the handset.
Any suggestions?
always good to see another florida person.
Can't say anything about the first since i don't own the device yet, a case may help though since my dad has a vibrant and he used to hit them, but after getting a silicone case he dosn't do it anymore.
As far as the seeing the screen goes, depending on your brightness setting the screen may be washed out. I normally keep my nexus one at about 40% brightness, but if i'm going to be outside for a day, or when i'm at the themeparks in orlando, i turn on the auto brightness, that usually brings it up to 100% in the sunlight which makes it readable.
Normally switching the brightness involves going through the settings, but there are many applications that give you a quick switch, i personally use the mysettings app that i have on my main screen so it's only two clicks to get to auto.
The screen is very viewable in the sunny Southern California sunlight, but no modern large screen smartphone like these are going to be great outdoors; at least the NS is usable (unlike the N1).
I concur with the other response that setting the screen brightness to max is obviously the best way to tackle this.
There's a very easy way, just install the Power Control Widget that comes pre-loaded on the phone. It gives you a bar with 5 icons on it for wifi, bluetooth, gps, google sync, and screen brightness.
The screen brightness icon lets you tap it for 4 different settings (minimum, about half max, maximum brightness and automatic). As mentioned above, with max brightness, the phone is very usable, for me in sunlight. At least as usable as my iPhone 4 and older iPhones.
Very handy, and also great for quickly turning off wifi and BT to save juice when not using them.

yeah powerstrip is pretty awesome, theres another app like it called quick desk but i prefer powerstrip.
My setup lets me double tap the home button and i have quick links to 5 widgets and then all my apps, a set list of shortcuts, and my recent apps as well.

glad you like it, to switch to auto just long press on the brightness it'll switch to auto, and then long press again to go back to your previous setting.
Its pretty serious for me as well, its like being on speaker all the time. Its there any way to change the volume range? If not this will have to get exchanged.

I am also experiencing the oposite problem to this, my earpiece even at full volume is still very low. May try to pass by Best Buy and see if i can get test out another phone and see if mine is defective.
Yeah i'm suffering with the same problem. I've even swapped the phone but the new one has the same issue.
Has anyone found a fix for this? I really don't want to have to swap the phone again

[request] vibration mod.

im sure everyone knows that the mt4gs vibration is a bit excessive. is there any way we can get a mod to lower the intensity?
My guess would be no.
The only thing that could change the intensity of the vibration would be the alter the voltage to the vibrator motor. (If you're not aware, all the vibrator is is a little motor with an off balance thing on the end)
If you give it 12v (or 5V, whatever the case may be) its going to vibrate the same amount every time.
What I think controls the motor is just a simple switch that allows power to flow to the motor or not. I don't think that switch is adjustable in a way that would allow it to alter the voltage going to the motor.
I could be wrong. But I don't think I am.
Now, what you could do is make something that turned that switch on and off really fast so that the vibrator motor got small pulses of power instead of a steady flow. That MIGHT keep it from ever getting up to full speed and result in lowering the intensity of the vibration. But it might back fire too. Vibration and oscillation are a quirky thing. Some more power could make it more intense while a lot more power could smooth it out. Conversely a little less power could make it more noticeable and a lot less power could make it less noticeable.
Think of your car. At idle speeds the engine might shake, but at highway speeds it might run smooth. But at 30 mph it might shake more than stopped or 60mph.
In other words....if it could be done it would be a work around. And there's no telling how well the work around would work.

Vibration/Haptic Intensity Diminished

I didn't use my phone for long before updating to N910W8VLU1ANJ3 from whatever was stock, but I noticed recently that the vibration and haptic feedback intensity is much less than I noticed out of the box. I remember remarking that the vibration and haptic intensities (turned up all the way to max in the settings) was actually far too strong. I'm not sure at what point things changed, I hardly have any apps installed, power savings are all turned off, but now with the settings maxed I find the vibration weak at best. Has anyone else experienced this? Should I try a factory reset? I'm thinking I should root and get going on some custom ROM's, but I haven't been too impressed yet with what's available for the non-US Snapdragon Note 4. Thanks in advance for your feedback.
