My Z Thor Batt drops fr 100% to 1% after 6 hrs. Run tests

My Zblaze Thor without warning has suddenly developed the battery dying completely after about 5 hours just being on not used after each charging cycle. ( This was with nothing on cell, location, gesture and just minimal Wi-Fi initally. Installed are 19 apps . The only app active was Floating Commander.)
I started keeping a log of readings for three days.

Setup - all apps off. Running Hibernation Manager. Initial tests with Eric’s launcher running. Then went back to standard launcher and noticed little difference.

I charged the watch using a Voltage Meter which gives you the Voltage(V), Amperage(A) and amount of mah (millamp hours) that the device receives during the charge.

Next is a sample charge process that occurred during the three days with similar results in all three tests of shutting down after about 6 hours.

1342 - Battery reading 1% to begin charge. Meter showed a charge rate of 4.87V, .30A.
1527 - after 2hr 15min charge, meter showed 371 mah charged to watch, with a 350 mah battery that should be about right for a full charge.
1528 - turned on watch, all apps off except hibernation manager, std launcher, emptied task manager.
1530 - 98%
1738 - 94%
2015 - 91%
2100 - 90%
2205 - 1% - watch would not turn on until I connected to power source. Battery level showed 1% on the level page and also in Power Saver.

Begin Test -  everything off, standard launcher. Just trying to see how the watch functions and get a basis for battery longevity under minimal operating condition. (Also note change at 1550 entry.)
2344 - recharge (4.95V, .29A) at completion it showed 100%. 359 mah charged to watch.
0005 - turned watch off.
0800 - 98% Tue Aug 1st Power on. (For same consecutive power levels each hour, I checked Power Saver app to verify reading.)
0802 - turned watch off.
0850 - 98% still. (Driving back from my daughters house so I left the watch off since I could not monitor it and also wanted to see what it did when the power is all the way off.)
1550 - 96%. (Left power on but turned on power saver and airplane mode as suggested by Sonia in another similar posting.)
1650 - 95%
1750 - 94%
1950 - 90%
2050 - 88%
2250 - 85% Made it 7 hours with watch still holding a relative charge. Good sign 6 hours was the most I got to in 3 previous tests before battery dropped to 1% or less. Hopefully means it is not the battery.
2251 - Power off
0825 - 84% Aug 2 Power on
0948 - 82%
1308 - 76%
1600 - 74%
1725 - 74%
1840 - 72%

0800 - 61% 3 Aug Power on
1010 - 60%
1143 - 53%
1622 - 47%
2232 - 30% - Power off
0907 - 30% Aug 4 Power on
1901 - 7%  (At this low of a power available anything other than checking the time occasionally would probably deplete the battery quickly.)
2213 - 7% - Power off
0815 - 2% Aug 5 Power on
1952 - 0%   Powered off      (Total Time Run 66hr 29m)

Aside: Not sure if these Android 5.1 watches live up to their hype. While it lacks the many additional features, my KW08 that I now wear daily is both a very good tethering and stand alone phone/watch that runs several days on a single charge. It tethers easily and I get all the phone calls, SMS and notifications from my phone without fail. Maybe we are trying to do too much with the Android watches with the limited battery capability they have. At least they are making progress in the right direction. Having this forum to work out the kinks helps. I like the concept and am hooked on a Smart Watch.

I intend to go through a process of elimination to try and determine what was causing my rapid battery drop. I will up date this post as I proceed and surely eventually find the problem.

Now that I know it is probably not the battery and am going to begin by uninstalling all the apps I’ve added to the watch and begin by installing several at a time and testing them to find the one or two that are probably causing the power to drop off like it was. I will start by installing the most useful and work in that direction. To begin I am installing: Eric’s Launcher, Settings Search and Home Switch.
Let the chips fall.

I am shifting the third test to a new post below because of the picture (attachment) limits in a post.

i think it got to do more with the mtk and the 4 cores than anything else, with my D5 and the S1\Q7 i get better battery life but the D5 which is almost the same as the 5.1 upgraded versions just with 2 cores gives way better battery life when i putted  it on airplane mode and saving mode  i barely felt it with battery life and with 3g always on i got about 24hr to a day and a half. i think they should go back to 2 cores or figure it out why the high battery draining especially with 3g on. 

Sonia I don’t disagree with what you are saying could be causing poor battery longevity. But that would not explain a battery dropping slowly from 100% to 90% and then suddenly dropping to 0% as I and others have experienced. I’m betting one of the apps or better yet a combination that when installed at the same time are causing the problem. We shall see if I can isolate my problem.

The Power Jive Meter/Tester installs inline between the charger and the USB watch cable and is very useful in monitoring power to the watch while charging. There are several models I use this one.

Link to Power meter

you got to get it to ‘deep sleep’.
there are troubleshooting apps on the play store to show you the misbehaving apps generating ‘wake locks’ / partial wake locks.

you will see long threads about this on xda.
. . . and i am a broken record on this . . . use greenify

Third Test
1503 - 1% on charger. Readings 5.19V, .29A

685.jpg
1549 - 36%
2305 - 36% - Power off (time on 15h 5m) Not sure what is going on but that’s what I am trying to determine. In reference to Ion’s post. I am not trying how to find a way to reduce battery
drain but to find out why on 3 simultaneous charges my battery dropped from 90% to 1% in an hour with basically nothing extra running. Also I was running “Hibernation” which is similar to “Greenify.” I test all the apps on my phone prior to  installing them on my watch. I just felt like Hibernation was a better fit for me. I could be wrong and will review Greenify again.

Next Test in new post.

i had the same problem on my lem 5.

here are the steps i took to solve it.

change the charger (1A 5V / DO NOT USE A 2A charger)

installed Repair Battery Life PRO (https://play.google.com/store/apps/details?id=com.batterycare.batterycarerepair&hl=de)
run this program every time you charge the watch. it relly helps (i was skeptic) i think there is a problem in the original power management.

don’t charge the watch too long (make an alarm for reaching 100% charge, i leave my watch 10 minutes longer and than take it off)

never had the issue after taking those measures
let me know it helps?

here my old thread
/thread/1350/battery-died-after-weeks

you can see the problem is similar to yours. not had anything to do with the apps installed (i use greenify same and never had an app listed consuming this much of power)
funny here my lem5 never go to deepsleep (using ds battery actually drops faster, i saw the radio has probs to shut down)

try as i post above. i bet your issue will be gone.

Hi,

can we please stop using “battery repair apps?” Look at all those apps and the permissions they need/use. Most of them are just a scam. The only thing they can do is (if you have root access) calibrate the battery tracking process and therefore correct the output of the battery indicator, they will never enhance your standby/usage time.

i know about the situation and normally i'm against those apps too, but this one actually did work for ME (doesn't repair anything for standby etc., it says it defragments the battery (i think it is something like callibrating - but i don't know either..... when i read about the app first i thought like holy crap, this is a joke). maybe its jreally just a graphic that makes me feel better

despite that, try the charger and stick to not charging too long.

my watch after all measures never had the issue of dropping power again.

true, leaving the watch in charging somehow has negative impact on batteryl life, i never leave it over night and i also installed an app which tells me when it is full charged, i have great battery life do'nt know if it is because of how i charge it but at least it does'nt do any harm:)

Sorry I don’t agree with some of the comments regarding charging the battery in these posts. I base this on my experience and actually monitoring the charging cycle on a power meter during my test. 

  1. The size of the charger does not determine the rate of charge. As I indicated earlier because you use a 2A charger does not mean it charges at 2A. It only means it has 2A available for charging. I have a 110A High Output alternator on my boat to charge the four large Gel cell Batteries. Heaven forbid if it put out 110A all the time.

  2. The charging circuit (Regulator) inside the device determines the charge rate. My Zblaze Thor charges at about .3A when on the 2A charger. My KW08 charges at .25A when using a cable and .17A when on   the magnetic charging base using the same 2A charger. My LG tablet charges at 1.1A when on the same 2A charger. When plugged into a 5V USB port on my computer the Thor charges at the same rate as on the 2A charger.

  3. I have observed that when I charge my Thor with it “powered off” when the battery reaches 100% all current flowing to the watch stops, “000” which is what I use to determine that it is fully charged and the charge cycle has stopped.  If the Thor is “powered on” while charging, once it reaches 100% the current flow to the watch reduces to supplying enough power to replace what the watch is using. If charging overnight I always charge with the watch off. 

  4. From my observations the charging circuit in our watches is very effective in supplying the power needed to properly charge the battery in a safe manner. I charge my devices from a lot of different chargers that have many different charging rates shown on the chargers. I have never had a problem unless you use a charger not rated large enough for your device. Example use a charger rated at or less than 1A for most tablets and you will probably get a message informing you that it is insufficient and will take longer than normal to charge.

  5. Seb84 I had already followed your post and performed your recommendations actually before my latest problem began. Thought it helped stabilize the battery circuit but I think what I recently experienced is not related.

  6. The procedures to charge different types of batteries, lithium-ion, nickel-metal-hydride and nickel-cadmium as an example are not the same. I don’t think everyone realizes or understands that and tend to lump all the procedures together. 

  7. I guess I am more old school. When I flew airplanes for a living you learn that more time spent analyzing a difficult problem usually results in finding and fixing the right problem.  I’ve heard that there is an app for everything but in my experience they often just add to the problem.

sounds quite interesting. i’m aware, that it doesn’t depend on the charger (1A/2A), but I always thought, that the flow is bigger if you use a bigger one (2A) and might cause issues because of that. I know that with the first charger (2A) my watch always heated a lot when charing. this is also gone with the smaller i use now (still warms, but doesn’t get too hot).
Maybe I was just lucky though. Would really be interesting if you can find the cause. keep us up.

Fourth Test
1225 - on charger readings: 5.2V, .29A on 2A charger. Outside watch case temp measured 90°F.
1435 - 100% Charge complete - 356 mah charged to battery. I also noticed that the charge rate began tapering off after about 300mah point was reached.
1437 - 100%  Sim card is installed. All functions, Wi-Fi, cell, etc Off. Power Save: off, Airplane Mode on. Eric’s launcher selected. Installed 3 apps: Floating Commander, Hibernation Manager and Speech Memo.
1445 - 99%  Aug 16 Power On
1605 - 98% Something strange going on with power saver app that I check to confirm battery status. Normally it shows the projected battery life in days. I don’t remember have ever seen the battery displayed like
            this before. I rebooted the watch but the app still shows the same.

1214 - 86%
1500 - 85%
1636 - 77%  Turned on Hibernation Manager(HM) and set up as before. Floating Commander is one of the apps that HM turns off. I looked at Greenify again but will stick with HM. Neither function fully unless rooted.

i see your temperature is also very high during charge. like me with the first charger i used. you consider this as normal?
since i switched charger, my temperature is (not measured), but just hand warm and charges almost as fast as before.

do you get the strange behaviour on all 3 chargers you use?

i remember a case with an android phone, that i used. the charger got broken (still worked, but the phone got extremely hot while charging)

i always switch chargers, if the devices get too hot. i see mostly problems like this arise, when cables or the charger itself has damages. even my fastcharge phones, never get to 90 degree.
I think you have another isssue, if it is charger or watch related, but the temperature can’t be normal.

Sometimes you have to reset to make things settle down.

Try a full reset yet ?
.
On XDA ( for phones… sorry… ) the kernel cookers will actually have a software switch to shut down known, troublesome ‘wake-locks’.
.
Again, sorry - we do not have the luxury.

seb84 l should have put the temperature readings in context. I live on a sailboat. The normal daytime temperature inside the boat probably averages 83ºF+ degrees, with our 90ºF+ degree temps here in FL. 
The readings were taken with a temp gun, which is very accurate. Considering your body temperature is 98ºF, 89ºF didn’t feel but just barely warm to the touch. If you are feeling a watch case that feels very warm to the touch it probably is warmer than 90 degrees. In addition the chargers getting warm/hot? is probably not abnormal. Most charging devices will get warm while charging a device. A watch though that repeatedly causes the chargers to get hot could indicate a problem with the charging circuit or battery in the watch.
Devices being charged that get too warm that could also indicate a problem. Unless you are actually measuring the temperatures with something other than your hand, warm/hot is just a relative guess. 

I wanted to add the temperature to my readings to assure those who thought my 2A charger was causing problems with overheating the battery and show it has no real effect.
So to answer your question, no I have not experienced, so far any unusual or abnormal behavior or temperatures in the watch with the chargers I have used. Next time I’ll include the temperature of the charger too.

Ion I am in the process of reinstalling all the apps that were on my device at the time the problem occurred. I am doing it several at a time to see if any one or two of them possibly triggers the problem. Its a process of elimination. Doing it this way will make finding the offending app much easier. If in the end I find that the apps are not  the source of my problem then you move to the next step. As you can see so far the watch has been fairly stable with the apps installed so far. There is also a tendency to want to abandon a test and jump to the next possible solution to speed up the process. Then only to have the problem reoccur and no real idea why and you are back to square one. Another mistake people make is assuming your problem is exactly like everyone’s similar problem and throwing their solutions at it hoping for a quick fix. Troubleshooting is a methodical process.

ok. i see you also use fahrenheit, right? sorry i’m lways thinking in celsius. 90 degree than means you can bake an egg on the watch…
