There is this general conception of how Bluetooth kills battery and how you shouldn't leave it on.The Mi band is the only device that doesn't kill your battery at all(I mean it literally) and has amazing battery life. I've had it for a week and it's gone from 63-44%.It's battery life is fantastic.No matter the device you have, if it has Android 4.4+ and Bluetooth 4.0+ then it shouldn't drain your battery.It's connection is completely over Bluetooth LE in such a way that the Bluetooth settings show no device connected but it can be found using the app.This means it's using just the Bluetooth LE code introduced by Google with 4.3.So Don't ask about Bluetooth on blahblah.....It does nothing to your battery.

China Link removed I'm in China. $22 because it's scarce.

Unlocks only xiaomiMiui devices(any device with miui v5+).If you wear it too tight it can hurt a little but usually it is comfortable and light.

It's straight forward.Any button with the words 下载 will do the download.Or just wait it's in the manual from the box :D

-No probs at all.I use it with my G2.I'll be switching roms to check but flawless on AOSP 4.4.

-It's connected to bluetooth all the time but it is completely LE unlike anything I've seen before.It doesn't show up in bluetooth devices and only its app detects it.Also the bluetooth icon shows bluetooth on but not connected unlike with a speaker or headset.This means it really almost never affects battery life as I noticed for the past 72hrs and that the connection is not active but completely on bluetooth LE.Syncing is done when u open the app without any pain.

-Call time vib is 3secs because it may need time to connect the band and send the vibration command depending on where you are.This is convenient if you go lets say to a store.It disconnects but as soon as u get back home say u have a call.Because the band doesn't need to be connected to ur phone all the time(power saving) it reconnects within the 3 secs and vibrates.But it's almost instant.Open an app on your device afresh and that's how long it takes.

The LEDs light up for calls,when ur close to ur goal(with 2LEDs) and when u reach your goal(3).Also for alarms,finding your miband and low battery(never had this yet).For notifications nothing yet.Vibs are only for calls.I wish someone would make an app for this notifications and LEDs changing with various notifications(it's a multicolor LED) for the mi band.It's only for calls for now.But it's xiaomi.That option may come.I got a firmware update when I installed the official app so yeah they do updates.This was obviously downloaded on the phone and pushed over and it took 20secs or so.

You never know if it is connected(only if u have the app opened) because it doesn't have to be every time.The band records data and when ur close it syncs when the app is open.The battery truely last long.It's on 51% from 63% after 4 days of intensive use.Also come on dude 10m is the maximum for bluetooth so don't expect magic here.

Good second question.

1.It works well.I didn't quite get it's smart alarm feature yet but if you set an alarm it vibrates 4 times on your wrist at the time of the alarm.I set two simultaneously as i find it hard to get up in the morning.The smart alarm says it can get you up in a 30mins range from the time you set the alarm so maybe when it detects light sleep during 30mins from the set time it will get you up.That's the only hit or miss feature but you don't need smart alarms just do a regular one.

2.It is a transfered alarm unfortunately.During my testing I noticed the mi band stores only motion and its app translates it into steps,run,sleep,blabla....Alarms and call vibrations are all triggered from the phone so if your phone is off you would not get up in the morning.Buetooth off is not allowed.

3.The motion tracking is good it does a nice job at not counting steps when using your "mi band hand" like during eating or typing or even closing your mouth when you cough(don't put it on your active hand though,all fitness trackers advice this for more accuracy).It's accurate and on par with the best fitness tracking tech available.It's not like S health or LG health that can give you 100 steps just for shaking your phone.The sleep tracking is magical.It works so well for me.Detects when I'm about to sleep,in deep sleep,light sleep,get up at night,wake up time...It does all that so well and if it is off maybe just by one minute or two and seldom happens.The sleep tracking is a winner.Well the only thing is you get info on your sleep but how to make it better is up to you.

No.I've tried myself.It is completely over bluetooth LE even while syncing.Only miui detects it.I guess a dev will have to start from there to get the "universal" detection part working(ripping the files and porting).

I'm L&R handed :-p but it is configurable for left or right hand use in the settings.You have to use it on your less active hand.It does a good job at not counting steps unnecessarily(using a mouse,greeting some one,typing .....).I've not seen it miscount like that yet.I'll post a video review here soon.Stay posted.

Reliable if you are close to your phone.For me 98%.

All in the app.But stats are reset everyday automatically and the history is stored on the device & found in the app.

At most 10 secs after long disconnection but usually around 5 sometimes less.I started taking a shower with mine everyday.No issues.Water resistance is great.I play tennis too and sweat alot.2 vibs with many LEDs for goals,3 with on blue LED for calls,5times no LED for alarms.
