Has anyone worked out a way to make the watch's battery percentage more accurate? Mine has reached the point that it shuts down at 90%.
[Other SmartWatches] Apokriphos:
There are several battery accuracy apps on the market. I use Battery Doctor, but there are others, such as https://play.google.com/store/apps/details?id=com.darshancomputing.BatteryIndicator. They all match up your voltage to your current %, and adjust as necessary (when rooted). However, I have not yet had any problems with % misalignment in Kitkat. Another way to fix this issue is to let your battery run down to 0% once every 1-2 months, to re-gage the % battery.
[Other SmartWatches] nk33:
You have a valid point mate. My watch was ok from 100% to 60%...then i will find that I will go to look at the time half an hour later and it will have switched off.......something weird going on here and I cant figure it out.

there are only 2 possibilities:

1) the battery app is innacurate (highly unlikely)

2) something is suddenly eating up the last 60% of battery really quickly...

either option doesnt make sense,

I will try another battery app and report back
[Other SmartWatches] Theo de Kok:
I have the same problem, but not at 60%, but at 89%.

In about 12 hours from now this will probably happen again. I'll wait untill the battery is completely empty, charge to 50% and switch on the watch. See whats happening then.
[Other SmartWatches] Lokifish Marz:
It's not an app causing the watch to turn off as 60, 80 whatever percent. If clearing the possibly corrupt batstats.bin does not correct the issue, the issue is much deeper.

There is a power profile that is created at time of compile. This power profile has stats like battery capacity, the draw of the display, radios etc.. There are other core level parameters as well that are done when the firmware is compiled. If these parameters are incorrect the batter level, cut off voltage and draw rates will be incorrect. The core level power management also affects this.

I have seen this on happen on CM ROMs as far back as CM6, AOKP, PA, Slim (you get the idea), and multiple MTK based smartwatches. This is why open source is critical as any developer could have fixed it and passed the fix along.
[Other SmartWatches] nk33:
ok, so to get this straight this is inherited from the kitkat signed zip?
[Other SmartWatches] Lokifish Marz:
It is either a bug in the original firmware, or a lot of folks have defective batteries all of a sudden.
[Other SmartWatches] nk33:
wouldnt write-off the latter - it is all of a sudden...
[Other SmartWatches] Parcaetron:
So, once again for idiots like me: In practice, what you're saying is that it is not fixable?

inWatch Z / Berkley Hackathon is a go!

OK so this has been a bit of a challenge logistically but we are excited to announce that on the 20th of Feb (IN 3 DAYS!) inWatch is teaming up with UC Berkley, Sparklab, Global inDevices, Citris and many others to put on #campusinwatch, a hackathon event at UC Berkley where teams will compete to create new apps and functionality for inWatch Z that make wearables enjoyable as well as functional. The winning team will be flown to Barcelona, Spain to attend Mobile World Congress! Working with the UC Berkley team has been really enjoyable, I cant wait to meet the students and participants! We are open to non-students being a part of it as long one person on the team is a student. Teams are 1-3 people. Please share and help #campusinwatch start trending, this is the beginning of the US launch and a great way to add innovation to what Z already offers. :cool:
[Other SmartWatches] Apokriphos:
This is very exciting and I am all for it. Out of curiosity, do you think you could include a link to your post in this thread

http://xdaforums.com/showpost.php?p=58916354&postcount=426

in all future documentation/correspondence concerning the upcoming UC Berkley Hackathon?

Some people who have responded in this thread may be interested (after all, they are already vested in the Inwatch Z) in participating in the competition. Perhaps you could aggregate a list of UC Berkley students who are interested but haven't found their team of three yet? They could probably find interested parties here as well. I am interested in participating.
[Other SmartWatches] inWatchUSA:
Great, glad you are interested and in the area! So if I understand you correctly, you want me to reference this post when I am talking about this topic on XDA so more people can have context and info about the details? Sure, no problem. I will work with some of my student organizers to get a list but in the meantime, anyone from the forum (such as you Apokriphos) should PM me their contact details and I may be able to facilitate a team match for you.
[Other SmartWatches] Apokriphos:
I have noticed this issue with particular apps, before I upgraded to KK. I haven't kept Clean Master running in KK.

For example, when I had clean master running, all of a sudden I would get a notification from Clean Master that SWApp Link is taking a tremendous amount of power. Following the notification, it will say that SWApp is using a lot of power when the screen is turned off, or some other reason (listed by Clean Master).

I suggest two things: that if you are having a battery issue, that you keep Clean Master running in the background, and see if it notifies you for any major power use during a complete cycle (from 100% to 0 - normal use).

Suggestion 2: Check your voltage in the battery app in settings, or even better, with Battery Doctor (I really do like these apps, once permission modified). You should use your voltage decrease comparable to your usage, and no steep drops when not in use. In an ideal world you could leave your watch alone from 100% to 0 and see a perfectly linear slope all the way down. Then you would know for certain you are calibrated correctly.

As LokiFish said, deleting BatteryStats.bin will cause your watch to recreate it fresh using current data, and this is advised for people who buy new batteries for their phones with different mAh. I think it would work here just as well.

This app apparently does the step for you: https://play.google.com/store/apps/details?id=com.vitula.batterycalibration

OK brought this up and with the our organizing team. This is how to get involved and find a team:

• register on the challenge post website (http://campusinwatchberkeley.challengepost.com)

• After you register, there’s an option to “Look for Teammates” on the site.

That should be all you need, I look forward to meeting any who decide to show up!
[Other SmartWatches] Theo de Kok:
Last night happened what was predicted, at about 89% the level decreased very rapidly that was at about 2am. This morning the watch was off. So I connected the charging clip and charged to 50%. Then switched on the watch and it showed 92%....... But what's even worse the watch is not behaving like it should.. The clock is always visible and pressing the powerbutton twice has no effect. Only a long pressing starts the power off procedure.

So I switched it off and reconnected the charging clip. It says 88%.......
[Other SmartWatches] Apokriphos:
Theo, try my suggestions in the previous response and let me know what happens.

Things I want to know:

1). What is your voltage at maximum charge?

2). What is your voltage at 89%?

3). Did you try deleting the .bat file?

4). Do you have the always-on display mode active?

5). What does CPU Spy say about your CPU usage?

6). What apps do you have running, and what does Clean Master say? I turned on this app yesterday, and it takes minimal power.

For comparison, I only use my watch for companion mode notifications, calls, texts, and time. I fully charged on Monday, and it is at 98% after two days, which is normal for me with low usage.
[Other SmartWatches] Theo de Kok:
I installed battery calibration. I started the app and touched "Calibrate now" (battery level was at 100%)., a popup showed SU granted access. After this nothing happens, is this normal? I tried it on another phone just to make sure no buttons are outside the screen, but with same result.

Now I have to wait what happens. Normally the battery lasts for about 3 days (with WiFi always on).

BTW the watch behaves normally again.
[Other SmartWatches] Lokifish Marz:
Clearing up some things.

MOST battery calibration apps delete the BatteryStats.bin and nothing else. If there is a core firmware discrepancy this will not fix the issue. It may however temporarily fix corrupt BatteryStats.bin files caused by deeper level issues that are corrupting the file.

100% to dead in no time at all

There are two main causes. Defective battery and firmware issues. I've already covered firmware a few posts back. So lets talk battery re/dis rates. If a battery is classed as 1C, it max safe re/dis charge rate is equal to the capacity. So a 500mAh battery should not be re/dis charged more than 500mAh. So if a battery is at 90%, and a couple minutes later it's dead, that requires a discharge rate well in excess of what the battery is designed for. You would be talking a dis rate over four times what the battery is rated for. That tends to cause batteries to explode or catch on fire. Have not read any posts about somebody's inWatch turning into a small fireball so we can eliminate that.

The fastest a 500mAh 1C rated battery can go from 100 to 0 is around 1hr. On the Truesmart with a slightly larger battery, Netflix streaming over HSPA+ at max brightness, max volume, locked at 1.3GHz, it takes a little over three hours to kill a fully charged battery. Using a "BurnIn" stress test app, I could never kill a TS in under two hours if the battery was good, but it did get really hot.

In some cases you can re/dis charge a battery at a slightly higher rate than it's specs. So a 1C rated can be re/dis charged at 2C but there is a noticeable impact the lifespan (charge cycles) of the battery. This would not account for folks here with near new watches having the exact same issue as those who have had them for some time. So again, firmware is the prime suspect.

Most smartwatch batteries are 1C rated

Power off charge status vs power on charge status

While sitting on a charger there should be no more than a couple percent variance in these percentages. EVER! If there is more than a couple percent variance it is a perfect example of a core level firmware issue.

Side notes

As some of you know I have owned a crap load of smartwatches. Every MTK based smartwatch I've owned has had this exact same issue. Every single one. Even the inWatch Z had it on specific firmware versions (I think it was v10 or v11. Can't remember). Even the AI Watch have reported this issue.

To my knowledge, there are no reports of this issue for folks with the x201 series smartwatches AFTER they upgraded to Dan's 4.4 based ROM. Even more support for firmware being the cause.
[Other SmartWatches] Theo de Kok:
This is exactly what I was thinking. I don't believe the battery in my Z is discharged from 89% to 0% in a few minutes. I think if the watch displays 89% the battery is almost empty and the rapid decrease is caused by that. The remaining question is: how can I be sure the battery is EVER charged to 100%?
[Other SmartWatches] Lokifish Marz:
Any app that tells you battery voltage will work. 4.2v is 100% charge. Even though the UI is not formatted to the display size, I personally suggest Battery Monitor Widget.
[Other SmartWatches] Parcaetron:
Is it at all possible to port the fix from the x201 devices? Are they inherently more hackable than the Inwatch?
[Other SmartWatches] Lokifish Marz:
The fix was done at time of compile and there are no build notes or info. So most likely not. Even if there were notes from the ODM, we would need source code and have to compile a build.
[Other SmartWatches] Parcaetron:
So, basically, there's no way to fix the battery unless Inwatch does it for us.

So, what say you, InwatchUSA?
[Other SmartWatches] Theo de Kok:
I hope for them they fixed this bug in the forthcoming 3G versions. It shouldn't be that much work then to correct our build and set a new zip ready for download.
[Other SmartWatches] Theo de Kok:
At 100% charge Battery Doctor says 4.1V. This looks not as 100% charged.
[Other SmartWatches] Lokifish Marz:
4.1v would be considered acceptable tolerance.

Now I'm not sure if it has changed, but 3.5V used to be the shut down V for Android. This is still a bit higher than the recommended 80/20 rule which is around 3.2v. If you app logs V then check to see at what point it is calling "dead" and look for large jumps/drops in V in the log.
[Other SmartWatches] nk33:
Think I am going to have to write my one off. 3 issues with it already and i only got it at xmas...problem was i imported it from China to UK

1) Phone dies at 60% battery

2) Camera gets condensation in it really easily ( i later realised this may be due to point 3)

3) the back cover on the watch has come away from the watch by a millimeter or 2 and wont go back.

What a waste of money. i wish i had waited until the watch was officially released in the UK. Where can i go now for warranty repair? i have no chance!
[Other SmartWatches] Theo de Kok:
Maybe Sam can do something about point 2-3, at least he promised so. Email InWatchUSA. Point 1 seems to be a firmware problem.
[Other SmartWatches] nk33:
thanks, i emailed him about the camera thing and he advised me to stick it in a bag of rice which will soak up the moisture...which it did, but the problem surely returned dues to point 3.

i have emailed him again and awaiting response. the problem is no repair centers in UK....

hi

i just order chinese ver. .i really wonder something i hope inwatchz owners will answer

waterproof..is it possible to washing hands without damaging phone?i found a bt a speaker that says ipx4 and in its info you can even use it under shower.same rating so i hope same waterproof for z
[Other SmartWatches] Theo de Kok:
The watch is splashproof, not waterproof. You can wash your hands wearing it (I do it all the time), but wearing it under the shower looks a bit too much.
[Other SmartWatches] swerwqas:
thanks for your answer

one more question, if you put accidently under water few seconds while washing hands ,it means watch needs repair?

if so do you take your watch backwards on arm to avoid contact with water. before washing hands ?
[Other SmartWatches] Theo de Kok:
I don't think putting it under water for just a few seconds will be a problem. Just dry it properly afterwards (putting it in a sac of rice is the best option). But try to avoid this. The electonics are nano coated, so they should be protected for a short time.

I don't take special precautions when washing my hands. The watch can withstand a few splashes of water. But a shower will be too much. I take off my clothes anyway when getting a shower, so I can get rid of the watch as well.
[Other SmartWatches] swerwqas:
thank you .it was very useful. and new 3g versions will come with new nano coating so do you think will be a very improved ip rating like x6,x7.is it possible or not with same sim card slot .i just bought z so i dont want to see a new waterproof rating model..))
[Other SmartWatches] Theo de Kok:
The new nano coating will undoubtly improve the splash resistence, but it's still not waterproof. I don't think this will be possible with this simcard slot and the powerbutton is probably also a problem.
[Other SmartWatches] swerwqas:
thanks for your useful comments
[Other SmartWatches] swerwqas:
i forgot to ask what about while sleeping .maybe we can sleep on the watch other uncomfortable positions for watch .do you remove your inwatch z before sleeping ?thanks again.
[Other SmartWatches] Theo de Kok:
No, never. I want to be able to see the time when I wake up.
[Other SmartWatches] Apokriphos:
Been very busy lately and haven't had time to reply to this thread.

As of currently, I am having no issues with my Inwatch. However, a few days ago I noticed my battery was draining much faster then normal. Did anyone else notice this recently, after using the customization options I suggested in previous posts?

Anyway, I checked my battery app, and it said that 50% of the battery is being taken by wifi. However, my wifi is off, and has always been off since reset. I disabled 'Expand' display in the advanced swipe down GravityBox options, and disabled the google apps in running programs, along with a few other things I don't remember off hand. I will elaborate on any other changes I made when I do further trouble shooting later. The issue disappeared and hasn't reappeared since, even though I enabled google functionality when I am on wifi. For those having battery life issues, I suggest checking usage and doing similar troubleshooting.

Further inquiry: I haven't had any issues with my battery accuracy, as a disclaimer. Notably, I do not force close MTKLog in running apps. For those with battery issues, do you let this app run?
[Other SmartWatches] Theo de Kok:
I had MTKlog running with all 3 options off. I'll switch them on and see if this makes a diofference.
[Other SmartWatches] Theo de Kok:
I charged the battery to 100% and have MTKlog running. Please note I have a batterylifetime of aprox. 3 days (I always have WiFi on).

At the end of day 1 the level was 90% (looked promising).

At the end of day 2 the level is still at 89%. This can't be correct.

So leaving MTKlog running doesn't seem to solve the problem.

Signal to bone conductive speaker lost, I checked and find out that problem is with electric stub. Can anybody help me to order it?

Can I send signal when speaking to inner speaker, not to bone conductive speaker.

hi

how to copy music to watch via usb laptop.(i enabled usb debug) but my laptop dont see my watch?? ..and

there must be a new thread about rooting and rom installation about this watch.. maybe can be diffucult to search and find in this thread.
[Other SmartWatches] Theo de Kok:
You should find the correct drivers for this, but I always use the app WiFi Filetransfer Pro for this.. But are you sure you want to play music on your watch? The battery won't last very long and unless you use a bluetooth headset it will be quite uncomfortable to listen.

And yes, rooting and rom installation can be difficult to find in this thread. I needed help for this too. But maybe someone will be kind enough to post a clear tutorial for this.
[Other SmartWatches] StridAst:
I listen to music and audio books all the time on mine. Battery life is mediocre at best so I need to charge it halfway through a days work. Bluetooth headset is a must for this.

When you plug the watch into your computer, USB debugging is NOT the option you want. Check your notifications when you plug it in. There will be one for copying files to/from your computer. Click on that, and its just another USB drive :)
[Other SmartWatches] Theo de Kok:
A battery has only a given number of charge/decharge cycles (I don't have the numbers for this one). I'm already worried charging it twice a week, let alone twice a day. You can't exchange the battery yourself, so the price your paying for your music will be quite high.
[Other SmartWatches] swerwqas:
i have no notification on pc and watch .can be related with rom ? .i didnt install any rom on it.

i dont understand bone cunductor speciality.presing ontable and on face same thing but in fist situation watch is very near ear so sound come more on ear.i supposed sound send via bone vibrates to and no sound to outside on even high sound level. .
[Other SmartWatches] Theo de Kok:
Just install WiFi Filestransfer Pro on your watch from Google Play. Don;t forget to check it in the compatability List. Start the app and it will display the address you have to use in your browser on your PC. Now you can transfer files both ways without even using an USB cable. The watch can stay on your wrist.

You should restrict the use of an USB cable. The charging clip is the weakest part of the Z., so make as little use of it as possible.

And don't play music on your watch. It is not designed to do this. Batterylife can be called more than excellent, if you make use of it as intended you can achief more than a week.
[Other SmartWatches] Theo de Kok:
If there is any room left, wireless charging would also be a nice option.

Fun to play with, not practical as a watch.

I bought this watch in December. I played with it for two weeks. I read all the information available on the internet. Since I do not speak Chinese, of course I couldn't read those sites, but I tried and I wanted to.

I have emailed several times the Inwatch people with questions.. Not one response from anyone. I can only deduce that Inwatch does not have the resources to suppost their customers once the watch is bought.

I have tried all the launchers, all the apps suggested here. Some good some bad. I can say it is an episode in trial and error. It takes a lot of time to use this little dandy. It is fun as a toy to play with. It is not practical as a watch.

The watch I bought was 250.00. It may have been constructed of the fines material and the things it can do are cool. But I am not sure people would pay a premium price for a toaster that was made of the finest materials if it could not do what it was made for, that is to toast bread.

I own about 5 dozen different watches. They all tell time and I don't have to be a developer or computer geek in order to see that the watch runs for a a reasonable amount of time. Not just a few hours and then the battery gives out or has problems. That would be a defective watch. Also, I don't have to take the watches apart and tweak the hands or movements everytime I want to find out what time it is.

I do not mean to complain, but I do not think this watch is destined for general usage. Perhaps that is one reason this website has not unique entries for the INWATCH but lumps it in with "other watches" in the smartwatch genre.

I should have just put the 250.00 in my drawer and left it, at least then I could go buy something else with the money. Instead, the little jewel sits in my drawer, hoping that someone will answer my questions, or that someone will post the definitive guide on the Inwatch Z that will make this little device worth having.

After reading the most recent posts on battery problems, I conclude this device not ready for prime time and that is too bad because it has so much promise and does so many things those other smartwatches cannot do. However, it still is a watch, and in my line of thought, at least I should be able to rely on it as a watch they tells time all the time and can be powered up for more than a few hours without having to be a computer technician that can tweak it when needed.

My two cents. Love the toy, no crazy about the watch.
