tips how to make battery better?

thanks

1. Turn off ambient mode
2. Set brightness to 1
3. Limit screen on time by disabling notifications on apps you don't really need to view from the watch, and always covering the display to turn off manually when you are done looking at it.

thanks!

Also, if you leave it in its charger, and don't use it, it's battery will stay at 100%.

Use a watch face that doesn't have a second hand.

1. Don't use a watch face that didn't come from motorola pre installed. Wait for google to open it up to developers. Right now the way the watch faces work is through apps and that uses more battery.
2. Ambient off
3. Turn off any crazy notifications you get on your phone that you dont care about like twitter

Actually getting a 3rd party watch face that doesn't have a second hand or animation helps battery life a lot.

I concur! Installed custom watch with no "seconds hand", ambient mode is ON, 8am to 10pm drains to 30-35%! Standard Minimal watch face with the same options = 10% at the end of day.

haven't tried it...doesnt seem too convincing to me.
Try downloading mini wear launcher. If you swipe left to right twice you can dim the screen to super dim. I use it when i'm in the office so i dont have a super bright screen for no reason.

The only thing that's made a noticeable difference for me has been turning off ambient mode. For the last week I've been wearing the watch for about 17 hours / day. At the end of the day I usually have 25 - 40% left in the tank. Today I decided to try it with ambient mode on. I'm 10 hours in and I'm already at 38%. So it makes a big difference to me. That's still not bad since I'm averaging 6% / hour so I could potentially make it last my normal 17 hours. But it's a bit too close.
Also, I know I can drop it on the charger for 10 minutes and I'll pick up another 10 - 15% or 2 hours of ambient or 3 - 4 of non-ambient time.

I've tried that super dim mode. It seems to be pretty good indoors, but I can't see ANYTHING outside. I wish the auto-brightness was able to use it though so I don't have to manually switch it.

With ambient off, how accurate the watch screen will wake up when you bring your wrist up see the screen?

Stop using your watch like a phone

Can you tell us what watchface from 3rd party you use that doesn't have second end
Thx.

Autobrightness does use the super dim mode for me. If I'm indoors and there's not a lot of lighting changing the brightness to 1 will usually make my screen brighter.

Even if you use a face with a second hand in facer, just delete the second hand layer and all is good

Does anyone know how to turn off fitness apps?

Hello Everyone,
I have no need for or desire to use any of the fitness features of the 360, such as the heart monitor or Fit. I always see the little heart rate monitor firing up and I see this as a good way of saving battery since I dont use it. Does anyone know how to turn off, or uninstall these? Thanks!

Great question.

please let us know if you find out

I haven't done it myself, but if you're rooted you can try disabling them via adb.

In the android wear app, select FIT for countsteps and show heart rate, then on watch select FIT and slide through to its options. do show step card OFF, daily goal NONE, and save fitness data off.
currently thats the only way i know how

It still doesn't work - mine keeps showing me the daily goal, almost hourly.

App that keeps ambient mode always on?

So I found this one app " Swipify" that lets me keep the watch face on full time. I like it but it drains the battery a bit faster then I would like. Also when charging the watch the round charge progress bar does not advance so I have no idea how charged it is until I take it off the dock. So I un-installed it. I am looking for an app that will let me keep the watch in the dimmed "Ambient mode" full time and then when I lift the watch to look at it, have it to the full watch face mode until I set my arm back down.
Anyone make such a add-on app by chance? :fingers-crossed:
Or should I start learning how to code apps?
Any chance they (moto) will update with such features?
Thanks,
-DK

I'm not sure if such an app exists, but I'm just about 100% sure that Motorola will never add this feature. The current 5.1.1 software version was significantly delayed because they were trying to optimize battery life. I think it's a combination of a small battery and an old, power hungry processor that is the main problem.

I find that since upgrading to 5.1.1 I can go the entire day on one charge in ambient mode but I have to leave the watch sitting flat in order to test it. But by the end of the day I still have 25-25% charge left with it running the entire day in Ambient mode as long as I do not get to many notifications during the day which of course I can control those with no problem.

Huh? What's the point of having a watch if the only way you can get it to work is to lie it on the desk and not touch it, oh and to disable notifications, aka the only thing that makes the "watch" something more than juts a watch?

That is why I am looking for an App similar to Swipify to keep the ambient mode on full time. And I only let it lie flat for a day to test the battery life and it makes it through the day with the screen on full time in ambient mode. So I know the watch is capable of doing what I would want it to use it for.
And I said "as long as I don't get too many notifications", I never said I disabled notifications. I still have those on.

Gocha. No need to be defensive, sorry for the misunderstanding.
Still seems like you'd always be on the hairy edge of running out of battery in a real-world scenario. Hell, I'm ambient mode off but tilt-to-wake on, and some long days I barely make it to the end of the day. Never had luck with even the fake ambient mode the Moto provides.

All good, sorry to come off as defensive. :good::highfive:
Been using it with tilt-to-wake turned off and I am finding that by the end of the day I still have plenty of juice left.
With Ambient on and tilt-to wake off I find I have about 35-40% left at the end of a 7am - 11pm day. That is with receiving some email and text notifications (maybe 15-20) during the day.
I know everyone has different uses and ideas of how to use their Moto 360 so everyone's setting are going to be different, but what I am after is a always on "dimmed" or "ambient" mode with the option to turn on tilt to wake so I could test the battery life both ways. I would also like to use my 360 for home automation control and I I know with "Autowear" it is possible but from the little testing I have done so far it would kill my battery way to fast so perhaps on a future SW that will be something I will be doing.
Pausing and starting Netflix or HBOgo or Plex from my 360 is working pretty good for me as a start.
Think I will try and contact the owner of the Swipify app and see what he can do for me...... :laugh:

With the latest update LCA44B, when ambient is on and tilt is off, the screen will stay on all the time. However with ambient on and tilt on, it is same as previous behavior, screen will turn off when you put your arm by your side.

Some newbie questions

Hi All,
Great forum, used it a lot with several devices.
So, I just got my Huawei watch and it is great!!
I do have some questions and tips that it will be great if you could help me with and I couldn't find answers to (sorry if its too long...)
1. Charging - what is the best way to charge it in order keep the battery life? like everyday few mins? everyday to full charge? let it drop until X%?
2. Always on option - is there an option to make it sleep at night? like I like this option very much, but as I don't sleep with it, I think it is better that the screen will be off at night.
in addition, do it harm the screen if always on working all the time?
3. Reset - do you reset the devise occasionally? like in purpose. I mean, on my Samsung S6 i know that once in a while I need to reset it to get a better performance.
3. Steps tracking - I was with the blue moon face and noticed that the steps showed is updated after few seconds, meaning that let's say I walked 50 steps, I stop, look at the watch, see the old steps count and after 2-3 seconds it is "jumped" and updated to the new count. in addition, if I stop, wait this few seconds and look at the watch, the count is ok - is this normal?
4. fitness app - which app to use with it that will sync the best with my phone? I installed Google fit and its not doing the job good. it looks like it count steps from the phone and not the watch, or mixed it together, In addition the distance and calories count is way not true, like it show the distance far low then the true (I updated my height and weight, over the app and on the watch) and the calories far more then it is.
In addition I installed the Huawei wear app and it looks much more accurate, showing the steps as the watch, and separate it to walking and steps, distance is accurate and calories as well. but the app doesn't look so good and looks like it missed a lot of other option.
In addition, I don't understand why the Huawei app on the watch is not showing distance but just steps count.
So, which app do you use? I basically want a nice app that will show my daily usage and if can, that will sync with the heart rate measure that i can take from time to time.
Can I sync it to S-Health that I have? or please recommend for another app.
5. Is there any nice watch face that shows not only the steps count but the distance as well?
6. Any other general recommendations?
I think that's it for now
Thank you very much for your help.

Although the screen should not be harmed if always on is working all the time, at night you can use theater mode to turn your screen off without powering down the watch. The easiest method of going into theater mode is by quickly double pressing the button on the watch. You can also go into the pulldown menu from the main watchface and swipe over to theater mode to do the same thing. This can save some watch battery if you have the watch off the charger all night or if the battery is getting low during the day and you want to squeeze a few more hours out. It is meant for if you're in the movies and don't want the light from the watch screen to distract you or others from the movie. To exit theater mode and turn the screen back on, just single press the button on the watch.
Btw your post may be removed since we aren't supposed to post questions here in the general forum. There is a Q&A forum however where any questions can be asked about the Huawei watch. http://forum.xda-developers.com/huawei-watch/general/notice-post-questions-t3367506/page1
Enjoy your watch!

From my experience, it is ok to factory reset your device once every two months or when you feel it has become quite sluggish although you mustn't expect the performance results to be visible right away after the reset. After the reset, all the applications from your phone will be resynced and the Google Play Services will begin to re-download its updates thus resulting in bad battery life and perfomance for that day until it settles down.

Great.
Thanks for helping.

I always charge the watch to 100% and wait until it goes below 10% to charge it.
When I take the watch off my hand I also shut it down and power it on again when I put it on. This gives me about 3 days of using the watch without charging.

If you put your watch on a desk the display will completely turn off after about 10 minutes, even if you chose always on.
If there is no movement detected for a certain period of time, the display will switch off. This can sometimes also happen if you are in a very steady position. My watch turns occasionally off while I'm playing Playstation and holding the controller in the same position.

I noticed that but as inconsistent.
Sometimes it did it exactly as you describe and sometime not. left it on the desk, half an hour and still always on worked.

I don't know the exact algorithm behind it, but I'm pretty confident that the display will switch off sooner or later. I always put my watch on my desk at night and every morning the display is pitch black.

Mi Band 4 - frequently asked questions

I've compiled a short list of frequently asked questions seen over various forums or points which were not clear to me (even as a user of MB2). If you find anything missing or incorrect, please let me know.
Q: How to track sleep?
A: Sleep is tracked automatically during night hours, Heart Rate sleep assistance can help in improvement of the detection of various phases. To view the sleep stats, open Mi Fit app and sync the band. Sleep/naps are not detected during day hours.
Q: Does Mi Band have automatic workout tracking?
A: No, workouts have to be started manually either from Mi Fit, or from the band directly.
Q: How to use 24/7 HR with less battery usage?
A: Configure "Automatic heart rate detection & Sleep assistant", detection frequency as desired. Do NOT enable activity detection - it will switch to continuous HR measurements whenever there is some activity detected (e.g. walking). When needed, use manual workout for continuous HR monitoring instead (which will also gather additional statistics).
Q: How to use a 3rd party watch face?
A: The most easy way is to use app like Notify & Fitness, Mi Band tools, etc to apply the watch face directly. Great selection of watch faces can be found here https://amazfitwatchfaces.com/mi-band-4/top. AmazFaces populates the "My band displays" in Mi Fit application.
Q: Is MB4 waterproof? Can I swim/shower with it?
A: Per standard GB/T 30106-2013 (or ISO 22810 : 2010(R2016)), 50m water resistance is rated as suitable for showering, surface swimming and shallow snorkeling. Diving is not recommended. After each submersion in sea water you have to clean the watch/band in fresh water.
Q: MB4 cycles through menu during water activities.
A: Enable lock screen on the band and try avoiding running water in the "down->up" direction. Shower can easily imitate slide up gesture and unlock the screen.
Q: MB4 detects HR when laying on the table or wrapped around inanimate objects.
A: "Signal-to-noise ratio of a real blood flow is sometimes very low so the algorithms are very sensitive in screening for any non-random components in the light variation, and when such are found they are interpreted as HR. So, the algorithms pretty much always find something which is not completely random and interpret that as a HR."
Source: https://www.wareable.com/fitness-trackers/why-heart-rate-monitor-work-on-toilet-rolls-6606
Q: What is behavior tagging in Mi Fit?
A: AFAIK behavior tagging is there only to help developers to make the band more accurate, once you stop the activity, data collected from sensors are uploaded to Xiaomi. It does not impact nor improve your statistics directly and it certainly drains the battery as sensors are being constantly pulled for data. When you start an activity, press the button in the upper right corner - it will switch to real time raw data of sensors.
Q: Is there a hardcoded minimum Heart Rate value (e.g. 47bpm)?
A: Band measures as low as 40bpm (if this value is actually 100% correct is hard to tell as it happens during sleep ).
Q: Are there 3rd party apps for Mi Band management? I do not like Mi Fit.
A: M̶i̶ ̶F̶i̶t̶ ̶i̶s̶ ̶m̶a̶n̶d̶a̶t̶o̶r̶y̶ ̶f̶o̶r̶ ̶a̶l̶l̶ ̶3̶r̶d̶ ̶p̶a̶r̶t̶y̶ ̶a̶p̶p̶s̶ ̶f̶o̶r̶ ̶t̶h̶e̶ ̶t̶i̶m̶e̶ ̶b̶e̶i̶n̶g̶.̶ ̶N̶o̶t̶i̶f̶y̶ ̶&̶ ̶F̶i̶t̶n̶e̶s̶s̶ ̶i̶s̶ ̶d̶e̶s̶i̶g̶n̶e̶d̶ ̶a̶s̶ ̶a̶l̶m̶o̶s̶t̶ ̶a̶b̶s̶o̶l̶u̶t̶e̶ ̶r̶e̶p̶l̶a̶c̶e̶m̶e̶n̶t̶ ̶o̶f̶ ̶M̶i̶ ̶F̶i̶t̶ ̶a̶n̶d̶ ̶t̶h̶e̶r̶e̶ ̶i̶s̶ ̶a̶ ̶h̶i̶g̶h̶ ̶c̶h̶a̶n̶c̶e̶ ̶t̶h̶a̶t̶ ̶i̶t̶ ̶w̶i̶l̶l̶ ̶w̶o̶r̶k̶ ̶a̶s̶ ̶a̶ ̶s̶t̶a̶n̶d̶a̶l̶o̶n̶e̶ ̶a̶p̶p̶ ̶i̶n̶ ̶t̶h̶e̶ ̶f̶u̶t̶u̶r̶e̶ ̶(̶s̶a̶m̶e̶ ̶a̶s̶ ̶w̶i̶t̶h̶ ̶M̶B̶2̶ ̶a̶n̶d̶ ̶M̶B̶3̶)̶.̶ ̶O̶t̶h̶e̶r̶ ̶a̶p̶p̶s̶ ̶a̶r̶e̶ ̶o̶n̶l̶y̶ ̶a̶d̶d̶i̶t̶i̶o̶n̶s̶ ̶a̶n̶d̶ ̶r̶e̶q̶u̶i̶r̶e̶ ̶M̶i̶ ̶F̶i̶t̶ ̶t̶o̶ ̶b̶e̶ ̶i̶n̶s̶t̶a̶l̶l̶e̶d̶ ̶a̶n̶d̶ ̶u̶s̶e̶d̶.̶ It is possible to use N&F and some other apps in standalone mode, for more information follow https://www.freemyband.com/ guide (root and no root options available).
Q: I don't see detailed stats (steps, sleep, heart rate) for previous days, only summary in history.
A: When on the detailed screen of the current day, swipe right to navigate to detailed stats of previous days.
Q: Mi Band keeps unfastening itself during sleep or when dressing/wearing backpack etc.
A: Try to wear the band reversed (strap loop away from you, fastening button towards you). Also you can buy a silicone strap keeper (generic 14mm or specifically for Mi Band on Ali/eBay/..) to keep band on hand even when accidentally unfastened.

Hello, I just have a curiosity regarding the effective frequency used by Mi Band 4 to track the steps.
Sometimes it tracks steps very fluently, almost in real time; other times instead it stops counting on the display and after a while it adds a group of steps in a bunch (it always tracks steps but on the display it's not always reported in real time).
Why does it happen?
Does the heartbeat frequency detenction work in the same way or is it different?
Thanks

In my experience, steps are updated in real time when there is a long enough continual activity (walking outside, running etc.). For short activities with a lot of breaks (around the house) it tends to update in batches. It might have something to do with "clearing up the noise" - band waits for "chaotic" small numbers to accumulate and then applies some kind of statistical filter to provide accurate number of steps. Also all activities must have 10 steps at minimum.
Maybe someone else has better explanation though..
Heart beat rate is being recorded by Mi Band itself at set frequency and displayed on the phone only after sync (or during workout). For some reason watch faces with HR display show different value than Mi Fit after the sync. So far I haven't figured why

Hi,
Is it possible to make the band vibrate when it looses BT connection? I tried using "Anti-loss my phone feature" in "Notify & Fitness app" but it says "Instead this option use native connection lost notification for best results". Where can I find this native option?
Best regards

As far as I know, this feature was part of the official firmware on Mi Band 2, but has been removed on Mi Band 3 and 4. N&F offers a workaround with alarms which are constantly being rescheduled, but as it's written in the instructions, this "beta feature" will most probably drain your phone and band battery very quickly. If you really miss this feature, you could try submitting a feature request via Mi Fit app and hope that it'll get implemented some day officially.

There is no custom firmware for MB4 as of now, only custom resources (languages, icons). Also I found an information that firmware must be signed, so unless someone finds a way how to crack this security mechanism, there won't be a custom firmware.
I find MB2 still very good, but nice big screen with custom watch faces and easy starting of workouts from MB4 is very addictive. Just curious - why do you find this "anti loss" feature so important?

I work at a large software company, we have on-call duty so I need to be available. When I want to go to the beach or to the swimming pool I would like to get notifications from my band. If I loose the connection to the phone and do not get a notification I might miss some critical alert.

I see. For your use case I would look for a smart watch with a SIM card. Using a smart band connected to a phone will be extremely limiting for you. Even if you'll receive the notification that you're out of range, this will happen more often than not - practically almost immediately once you're in the water or a couple of meters away from the phone, so I'd expect to be notified very often. Btw. MB4 shows on the watch face once it's disconnected from the phone, but it's only a small icon - there is no vibration or any special notification shown. It might help if you glance at your band every now and then..

Do you have any recommendations? I prefer android and would love it to be completely standalone (I'm not sure about eSIM).

Using a smart band connected to a phone will be extremely limiting for you. Even if you'll receive the notification that you're out of range, this will happen more often than not - practically almost immediately once you're in the water or a couple of meters away from the phone, so I'd expect to be notified very often.

I did not know that bluetooth range is reduced to a couple of inches when the device is under water :/. If MB2 would vibrate every time my hand goes under wanter then I do not want it. I guess I can use MB4 and "mi bandage" / "fitness & notify" phone loss feature when I go into the water with an interval ~5 min to remind me to get out of water and check to see if there are any notifications and I can disable it when I do not want it.

Personally I don't have any experience with smart watches beyond Mi Band, but the usual choice seems to be Samsung Galaxy watch series.
Bluetooth in general doesn't have great penetration of solid obstacles, in my experience it reaches about max 5 meters with one or two walls in the way, and often it's even less. Situation is slightly better in open space. Quick Google search says, that watch will lose connectivity just about 3 cm under water (which may be the case with eSIM too, I couldn't find more info about it). With WiFi it's about 15cm (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3355409/). I guess that simple reminder to check your phone will be probably your best choice if you're planning to spend some time in water (or leave someone near your phone and he/she will let you know if any notification arrives ).

I work at a large software company, we have on-call duty so I need to be available. When I want to go to the beach or to the swimming pool I would like to get notifications from my band. If I loose the connection to the phone and do not get a notification I might miss some critical alert.

IMHO the app Mi Bandage can emulate this behaviour by continuously setting up an alarm on the Mi Band a few minutes in the future. So the alarm will trigger if it's time doesn't get updated by the app because the connection was lost. I wish I could emulate this behaviour with Tasker somehow without needing the app. (currently using Gagetbridge and additionally Mi Band Tools just because of the gesture support for Tasker. But I can't recommend because Mi Band Tools is very annoying regarding asking you to enable notification access for the Mi Fit app even if it's not installed)

This is exactly what N&F does. Though prolonged use will have impact on the battery as it needs very often wake locks and data synchronizations.

How can I install 1.0.7.0.4 on miband four?

From N&F app. But you need to remove Mi Fit (or replace it with patched version), otherwise it will reflash the FW with the latest official stable version (1.0.6.16).

Is there any posibility to get sleep data (REM) in realtime from miband 4? Raw data don't interesting. For my project with arduino and etc. Or maybe sensor + sleep phase recognition.

I don't think that it's possible. Sleep is calculated afterwards, only after the sleep has ended, and from raw data gathered during the night. For example start of sleep is using historic data - e.g. no movement for 5 minutes, add canditate for sleep start, if no further major movement detected within 30 minutes, make it permanent, if steps detected, cancel sleep tracking. You can't have this kind of data in real time. Also band itself doesn't do any calculations, the sleep processing is done in the app.
