What gives you better battery life - keeping it on Auto or setting it manually to a lower setting?
People say auto brightness affects battery life because it utilizes CPU power. I call shenanigans on that though because it will use very little CPU power... I vote AUTO.. cause if your out in the sun and your settings are set to low... You are just going to tweak them to accommodate your needs.

I have mine set on auto, but it doesnt dim or brighten up.
Bet it does! just when it needs to brighten and dim, you never notice. I thought the same thing until I played with it for a while thenI noticed it working.
auto eats more power, but it does what it needs to.

It uses more power to make the display brighter. Think of it like those 3-way light bulbs. The lowest setting is like 25 watts, the middle 50 watts and the brightest is 100 watts.
There is a widget that lets you change it manually between 33, 67, and 100% brightness with the touch of the button. I have that on my 2nd screen (along with WiFi, GPS, etc) and keep it at 33% most of the day every day.
I use auto due to ease and I easily get through the day without charging. I do use manual if I am in a dark room b/c auto just doesn't seem to dim the screen enough.
I like the 3 setting Brightness widget also. I like to set it where I prefer, didn't really care for auto. Don't know about battery savings with either one.
Is this a stock brightness widget or do I have to get it in the market?
I keep mine low...
24 hours later... 55% battery.
I use battery level its a small widget to change every 25% its great my battery is amazing Im at 58% after 12 hrs using 25% the brightness level and of course WiFi always on and turn in mobile network when I leave the house which saves me SO much battery

I always run mine at 100% brightness. I don't care about battery life. I prefer a bright screen.
Using a widget is probably no bad but I just auto , come on the phone was made with the sensor for it and it doesn't use much battery unless you have it a t 40% or lower all day long and struggle in the sun. I been using in auto since the iPhone I changed it for Android but i went back to auto cause it waste time just to change the setting everytime and annoying too
If you don't have an Evo3d well you don't have an Evo3d
Mine is manual and i see great results same with evo 4g.

It's a stock HTC Widget, but they also put powerpanel in there. I just think the HTC widgets look nicer.
I wished the auto brightness function had user-defined options. I agree with it being way too bright at night.
I have been using the 3 setting brightness widget/button. Usually always leave it on medium till I'm at home with the wall charger then I use max brightness.

The best widget I've tried is Brightness Level made by Curvefish. You get easy access to preset levels, a slider to adjust brightness to any level, and enable or disable auto brightness.

it would be nice to find a widget that sets a daytime and nighttime level. i use tasker but i think it's just too big of a program for just this one little thing.
I shut off my auto brightness off yesterday after a few hours to see if it made a difference and set my level to 40%. I don't know if it was a fluke or not but after 13 hours when I plugged my phone back in to go to bed, I was at 63%.
That is a huge difference from what I have been seeing. I am going to see how it turns out today with the same setting but I must say it is looking pretty good so far. After 2.5 hours with some texts, a little web surfing, some theme changes and emails and I am at 93%.
I will post back my results later tonight. I am also using power control plus which has a brighness widget that you can set to a percentage for each hit. So in case I need fill brighness, one click and I am there. Another click I am back to 40%.
In Honeycomb, in an effort to conserve battery, I changed my WiFi Sleep Policy so that the WiFi would always turn off when my screen was off. This seemed to work well, and my WiFi would always immediately connect as soon as I turned the screen on my Prime back on.
However, in ICS, if my screen has been off for a while, there can be a little delay with the WiFi reconnecting when I turn my screen back on. The delay can be anywhere from about 10-20 seconds.
Has anyone else noticed this? Also, has anyone else done any testing to see how the battery life compares when using these two different policies? What are most people setting their sleep policy to?
I have noticed the same thing. Not a huge deal most of the time.
As for comparing between the two policies, I usually leave the fully charged Prime sleep from 7am til 6:30pm while I'm at work and with WiFi always on it will show around 95% by the time I come home.
With WiFi sleep when screen off the charge shows a charge of 98-99% by the time I come home. That might not seem like a whole lot but it adds up over a couple of days!
Of course that comparison was made with Honeycomb; I haven't had ICS long enough to try both modes and compare. But so far after one day it seems to be similar.
My only issue with having WiFi sleep is that many times the weather widget will not update and I will have to manually refresh it... Anybody having the same issue?

I noticed that as well. I noticed my prime had been saying the same temp for a day and a half almost 2 days which I thought weird, so I checked and it hadn't updated for about a day and a half.
So there are three options
Keep WiFi on during sleep
1) Always
2) Only when plugged in
3) Never
What option to set if i want Wifi to turn of after some time of when phone sleeps. Previously i had set the option to 15 minutes but that option is not available in ICS and i m having a hard time understanding how these options work on my sensation.
Can anyone explain what each of these options do ?
Thanks
Problem: For most of us, the big, bright screen eats up most of our battery power. One advantage of LED screens is the darker you make them (including using dark backgrounds), the fewer milliamps they use. So you could turn off auto-brightness and manually adjust the brightness to darker settings. Far from perfect since you must adjust it every time you go from a dark building to a bright sunny day - and vice-versa. A pain.
I recently installed Screen Filter by haxor industries. They only tout its ability to make the screen really dark for night-time viewing, with the side benefit that it will also save some battery. It works great for that. It will make the screen much, much darker than the lowest stock brightness level (even using apps which take it to its absolute lowest setting, which the stock brightness slider won't allow you to do). I've found going to 25% is perfect. It makes the screen a little gray when you go really dark but its a minor downside.
Solution: I realized it can also be set to only dim the screen a little, like 75%, or 80%. Not helpful at all in a dark room since it is still very bright. But I also noticed that it works along with the stock auto-brightness setting. So you can apply a fairly bright setting to Screen Filter and leave it on all the time, effectively lowering the stock auto-brightness level a few notches no matter what brightness it picks. You still get the benefit of auto, and you get to reduce the battery draw all the time, on the single-biggest battery user on the Note.
You can save multiple widgets on the home screen, each set to different levels, so you can turn off the 75% setting and apply a 25% setting at night with two button presses. Or turn it off with one button press in bright sun. And/or you can add it as an app shortcut which allows you to adjust the brightness from an "ongoing notification" in the notification bar.
I'm starting a test today, leaving mine on 75% all the time with auto-brightness on, and using 25% in dark situations which doesn't happen often. I expect this will produce a noticeable improvement in battery life.
are you representing the app ?...or for the company?......

Look at my post count and how long I've been on this board. No.
The app has no ads and is free, BTW.
Looks promising. Ran mine down to 5%. 15 hours on battery, 4 hours of screen time. Most people here only report 3 to 3 1/2 hours of screen time.
I just maintain my brightness, im anal like that. Especially with that notification shortcut for increasing or reducing brightness someone recently posted. i am good to go.

I use screen filter and did not think to use it all the time with auto brightness, I will give it a go thanks for the idea.
Simply setting my brightness down to about 25% and leaving it I get 4.5~5 hours screen on time.
This is still working well for me, with a noticeable increase in battery time.
I've adjusted my lowest setting from 25% to 30%, too much of a gray cast to the screen at 25%. 30% is still pretty dark in a dark room. The 75% setting is good most of the time but I've found in full sun I usually have to turn it off.
Lol at wish777, ya he is promoting a free app. Do some research before you assume and accuse someone of something.
Thanks to op for app suggestion, it works great. I downloaded it, you must of brainwashed me with your deceiving free app propaganda

Yes, the screen is almost always the biggest battery hog in these devices. Thanks for sharing that app.
Here is another, https://play.google.com/store/apps/...XJ2ZWZpc2gud2lkZ2V0cy5icmlnaHRuZXNzbGV2ZWwiXQ.. It is FREE, so no acusations. I am not the dev and I didn't even play one on TV. This one is nice because you have a single widget that pops up a window with several options of screen brightness.
ANd if you are using Juice Defender Ultimate, There is Brightness feature built in that do the same thing.

Looking at the reviews for that app, someone said that Dimmer takes the screen down farther. I tried Dimmer before Screen Filter (only for night time viewing) and can confirm it will take the Note down to the lowest allowed 10/255 where the stock brightness only allows you to go to 30/255. However, Screen Filter will make the screen even darker than Dimmer. Something to consider - not bashing any of the above. Just sounds like Screen Filter is better both for daytime and nightime use.
I use screen filter to read at night. I'm not sure about the battery savings but with screen filter set at 12.5% the screen is unreadable unless you are in a dark room. In a dark room at that level white text is more gray than white as well.

good thread. i installed S.F. in Feb, def works great for me. but i prefer manually adjusting screen brightness via the shortcut "Slider" at top of the Gnote's screen
I use this app for night time reading. It works great and I didn't know about having multiple widgets with different darkness settings. Thanks for the pro tip!!!

I'm getting just shy of and over 4 hours screen time, depending how long I'm actually talking on the phone for that day. Not using this app btw, wifi at home, LTE everywhere else
Actually, for me, the screen is the number 3 item for killing battery, trumped by phone calls at number one. And I dont even spend that much time on phone calls, usually less than an hour per night (I wish I could find a solution for this besides not making / taking calls).
Under Settings->Display->Auto Adjust Screen Power, I have this DISABLED.
This helps significantly with the 'greys' on a dark screen (to the best of my limited comprehension, this is being called black crush?) AND virtually eliminates the 'banding' I was seeing initially. Strangely however, I had to disable this option and it took a day or two before the banding almost completely disappeared (I was seeing it ALOT on the Google Market initial grey screen before it loads in the ads).
I use Auto Brightness.
I also have Settings->Power Saving->All Options are DISABLED.
Anyway, you might try disabling the power saving and auto adjust screen power and see if that helps with black appearing grey using the app you are mentioning.
Use the 15 toggle mod to turn of all cellular data when you don't use your phone. You can still receive messages/calls but there is no reason to leave mobile data on while at work or you're not using the phone.
I usually leave school with around 90% battery left and I'm on school from 8-1. All because I leave data off while not in use.

I find that gf2 sleep tracking is really inaccurate. I've had the band for almost a week now and I can say so far it has never properly recorded my sleep for even 1 night.
- 1 time it just recorded as inactive the whole night
- I go to sleep at 11pm usually but the few times it recorded, it was several hours later
- sometimes when I take a noon nap it records but usually incomplete.
- today I woke up at 7am but I got a notification at 8.30 asking me to rate my sleep.
Coming from a fitbit charge hr, this band has been a major disappointment so far other than its prettier gfx.
Is my experience typical? Is there anything else I can do to make it more accurate? TIA
I find that my GF2 usually estimates the time I go to sleep accurately but usually thinks I got out of bed 10-15' later than I actually did. It always waits an hour or more before it shows the "how did you sleep" info though, for some mysterious reason.
I have been using the GearFit2 for some time, and find its working near perfect for me. For me I find the accuracy is better if the Fit is snug against the wrist.
This morning I got up at 4AM, and I checked the report, and it picked up my movement at 4am.
I also find that you should restart your device like once every two weeks.
I find the Fit 2 to be spot on - amazingly so.
Could be the fit to the wrist as mentioned above.
Hi
There is an ongoing thread about the new 2.3.7.0 Stratos firmware and whether its OK to update.
Can I ask if anyone who has updated has found that Continuous heart rate monitoring is now broken - symptoms are that resting heart rate is reported as '--', there are gaps in the data, and when you look at the back of the watch the heart rate LEDs only work in brief burst of about 10 seconds, the go off for a minute or two (completely different to continuous previous 2.3.5.0 behaviour)
Hopefully the images from the Amazfit app show the issue better than I can say in writing..
Heart rate images from 10th December (2.3.5.0) and 13th December (after update to 2.3.7.0) are in the attachements below this post.
Hmm, as I explained you in another thread. I'm pretty sure that continuous HRM is not really continuous. Just checked again and the LED on my Stratos is off right now even continuous hrm is on.
However, your graphs clearly show that in the latest release, continuous HRM is even less continuous. Definitely has unusual gaps.
With the oldest FW, mine looks like the first one you've posted.

Just double checked. After zooming, my continuous HRM looks like second one you've posted! Also has gaps. However, watch and the app are showing resting, min, max, average HR. For resting takes some time to show up, at least a day. And you did factory reset...

1. Known bug: currently Pace/Stratos do not record reading bellow a minimum value (I think it's 47bpm), Huami is already aware of this;
2. Obviously, continuous doesn't mean it measures heartbeat every second, first it needs about 15s to get just one reading, and then keeping the sensor on all the time would kill battery. IRIIC it reads every 1 or 2 minutes;
3. No resting rate: first check that your profile is correctly filled, then you must use the watch at night, while sleeping. If both are OK then you need to factory reset: first try with restoring old data (it usually doesn't fix anything), then without restoring old data after pairing again.

You are incorrect about a 47 BPM bug, I see min 43 BPM on December 14th, Min 43 BPM on December 15th, and Min 42 BPM today as I write this post. I saw readings below 47 before with 2.3.5.0. Maybe this broke in 2.3.6.0 / 1 which I did not use?
Secondly, continuous HR with 2.3.5.0 meant LEDs flashing on all the time. Almost every video I have seen on Youtube with Stratos reviews show LEDs on back always flashing.
This is how things always worked since September with 2.3.5.0 and it did not kill battery, only 2% overnight, or 5% during the day if no GPS or Bluetooth battery. It was always VERY accurate too, resting always match my Wahoo Tickr within 1 or 2 beats as you can see from Wahoo Tickr screenshot vs December 10th screenshot in 1st post with 2.3.5.0
See this Youtube video - everytime he turns over the watch, LEDs are always flashing and I can see from this setting he used Continuous HR to on.
https://www.youtube.com/watch?v=LsxKihwRNV4
In my view always on LED the correct behavior and exactly as Fitbit Surge or Garmin Fenix 5 Plus which also have 24/7 LEDs in continuous mode. As a general point, Fitbit Surge and Garmin Fenix offer 5 to 7 day battery with proper continuous HR and Stratos with 2.3.5.0 also did this fine.
I've spent the last 3 days resetting / rebooting / repairing and this simply is not a fix - sorry! 2.3.7.0 is broken, at least on my watch and cannot be fixed my end. See HR track from yesterday (15th December)
As a very experienced user of this device with over 660 miles logged, I know how it worked since September 2018 with 2.3.5.0 and how it doesn't work now - this isn't something I am doing wrong.....

Sorry, but there is not much to be "very experienced" about. Regardless how many miles you have logged so far. With that logic I'm about double experienced than you
Anyway, I agree that they're messing up with FW, fixing one bug, making two more. Instead of wasting your energy here on xda forum to prove us something, turn to Amazfit instead. Open the ticket and prove to them. It's good for all of us. Actually, all of us should open the ticket for every bug, every problem we find.

The reason I put my usage is that it's a bit frustrating people saying reboot or repair - this is really like a IT support cliche telling you to turn it on and off again! I know how this works and its just wasting time with a firmware defect.
I have reported all the bugs I have found in Stratos since September, including uploading log reports from the phone directly from WIFI, filling reports with Amazfit and have had no response ever from them. Just an auto-reply - never any human follow up.

That's odd. I have couple of threads with them (more than 10 ). Sometimes they are not very responsive but in couple of days, they usually answer. Of course, first couple of answers are generic but if you are persistent you may get trough even to the dev team.

Hi, yes that is link - this is what I get back - always this, nothing more...
Dear cumbrianrunner
Thank you for contacting us. This is an automated response confirming the receipt of your request, and it is being reviewed by our support team.
Please note, Amazfit Support is available Monday through Friday, 9:00 a.m. - 4:30 p.m. PT. All support inquiries submitted outside of normal operating hours will require additional time for a response.
I think that link may be for people in the USA only - I am in England, and one of the questions they ask is about sales channels. I suspect non-US reponses to sales channel questions get filed in the bin too be honest
Well, try with US channel then
For me continues heart rate is working on 2.3.7.0. The lights should flash every minute for around 10s. It is measuring in one minute intervals except during activities. On Apple or Suunto continues means 10 minutes. On Garmin each second. What I recognized is that my resting HR is now relatively higher than before. But now it is winter and I am doing much less cardio training than in summer. So it could be true. Resting HR still recognizes resting days, hard workouts, illness or drinking alcohol correctly.

Well I have another bug - I am about to go out for a run, my usual stretching exercises puts my HR at about 60-65 BPM. Stratos with 2.3.7.0 is going nuts with continuous readings - spiking at 105 BPM, drop back to 78 BPM is next read cycle, then back to 96 BPM on other cycle.
Wahoo Tickr and Fitbit Surge have me around 60-65 BPM which is correct.
I could report this, but I suspect this would go into the 'too hard to fix' bin...! But will try pretending I am in the USA today
I can't say much about the stratos continuous heartbeat, but my Pace (FW 2.8.1.0) regularly shows a rate of 180 - 200 when I easily can make a conversation....

So maybe 2.3.7.0 fixed the low HR minimum (I am not sure because I do not use this feature normally, but I know it existed for 2.3.6.0/1)... I have just enabled continuous HR for the last few hours, and I am sure the green leds aren't on always. I also got the graph showing the resting rate.
guys, throw all that stuff at me, i'll try to prioritize it again.

The same crap has been going on with the Pace for the past year. I was in touch with support for months and got a constant reply that it'll be fixed on the next ROM. This reply was repeated for months, until the warranty ran out, with me supplying the developers with data, screenshots and uploads directly from the watch. I chucked mine and put it down to buying cheap ****, and useless support. A friend who still has patience tells me that they still haven't fixed the HR issue.
Have fun with support, I hope you have better luck with the Stratos.
