Batery percentage issue

[Edius]

hope that you sold "well" your 9x, because in my opinion is not worth to go from a 9x to a T9...There are not enough stronger point on T9...

Yeah, 9X was sold with 235$ and T9 with case and DHL delivery was bought with ~275$ from Aliexpress.
In my opinion 40$ worth the change.
I'll see..for now I have nothing to loose.

So do you think that if I change launcher for example to Nova Launcher the battery problem could be solved?

I have tried with Apex and Nova before with no luck.
It's not about launcher, it's aboutGoogle Now who will "kick" CPU at regular times (~30 minutes) and deep sleep will not lock battery stats.
Now I'm thinking...if anyone will set 3 or 4 mail accounts to update at 30 min. period it will be the same thing.
It's all about deep sleep who locks battery stats...if idle time is too long battery will not be reported right.

L.E. Sorry for double post.

Are you sure that is how it works? I use none of the aforementioned launcher (GO Launcher here), got one not at all frequently used eMail account and keep the tab in Airplane Mode all the time. Even leaving the tablet untouched for 1-2 days a piece, I have only had this problem happen once (and the way I solved it is above) and never again.

Yes, I'm pretty sure.
Airplane mode will stop all network communications (WiFi and 3G) unless you will put WiFi on after that.
It's not about WiFi and 3G, accounts setup from your tablet will kick in at some times and will be synchronised at specific times (Google Now works in this way).
To be convinced, restore your Cube to factory defaults and leave it idle for 2-3 hours with no additional software and Google account setup and you'll have battery stats locked for ~ 1,5 hours, no matter how hard works in this time.
Some of us see this phenomenon, some don't...it's about software we use, account setup and synchronisation.
Tapatalk, EMail and GMail accounts, how Google play is set (automatically search and update apps), all this may prevent battery stats locks.
I like to have an economically setup and this is not possible with Cube 9X at this moment, was crucial and unsolved for me and i sold it.
Maybe at some time a newer kernel will solve this, but for now I don't have more patience to wait for that.

Air Plane was mentioned to show that it was in a low power environment (<50mA per hour), so I wouldn't call it economically unfeasible but to each their own, I guess.

You have 1439 tablet? Am I right? I have 1430 white and I'm facing this problem sometimes. I can always solve the problem with the method you named above but it always come back sooner or later. Now I have enabled Google Now (still stock launcher) and everything seems to work great for now. I will be updating how it goes this time.

And mine was 9X 1430...
I'll have to check a few things to confirm my assumption, little difficult because I do not have access to the tablet, but I'll keep you updated.

Yeah, 1439, white 16 GB (the grainy batch).

For I can not check (9X Cube was sold a few days ago and is impossible to contact buyer), those affected by this bug can try to keep the tablet without protective cover several hours.
I suspect that magnetic cover can cause this bug.
Some of us use classic covers like this,I had this type .
Arrived at this assumption because at first for a few days I had no cover and I have not seen this bug ... or maybe not caught my attention.
If this is true, could be very easy to remove magnet from cover.

Cover and battery

I don't think that the bug is related to the cover. I used my tablet about 4 months without cover and the battery percent got still stuck sometimes. Then I bought a cover and everything was same.

I have now enabled Google Now and battery percent has now worked well (with the cover)! I still need more testing to know for sure.

By the way, does your cover turn the screen off even when you fold the cover to the back side of the tablet? My cover does. Same problem that Atrak has (check this post). This is the cover I have. Sligthly different than yours above.

Vohukain,
I have a cover as yours (orange colour) and it does NOT switch off the screen when folded on the back of the tablet.
I'm sure you have a stronger magnet on your cover: you can fix it by put a metal plate on the back of the tablet in such a way to reduce "magnetic power" when the cover is folded.

In any case the cover is not related to battery percentage issue.

I have magnetic cover from day 1 and no problem with my battery

Thanks for the information! It is not bad problem because if I fold the cover to the back side and screen turns off I can just double-tap to turn it on again (Firmware V2.0). Then the screen remains on as long as I fold the cover back to front side.

Also try to charge tablet with a good quality charger.

I found out that the "chinese" 2Ah charger, that came with the tablet, takes forever to charge to 100%. Then I tried with my samsung S3 charger (1Ah) and it completed a full charge faster!!! I am still testing it, but I am sure that a good quality charger makes a difference.

The opposite can also be true... I've got some tablets that just will not charge correctly using a Samsung usb phone charger, but work perfectly fine with the usb charger they came with... don't make the mistake of assuming a higher quality charger is better just because the original one is cheap... any charger may not work if the voltage and amperage aren't in the proper ranges...
