probably not your battery yet —
power consumption is an important thing to question for smaller devices (and laptops too), so settings make all the difference .. I don’t have my iwork8 with me, but I do remember a win10 setting that was not set correctly .. it was set to stay connected to wifi when the devices was in ‘sleep’ mode. sleep mode has set power states for different parts of the device .. screen, cpu, etc .. but the wireless radio doesn’t use the cpu and such to stay connected to your wifi network, and ‘staying connected’ isn’t as easy as one might think. some receieving and some transmitting = power use.
It’s in the win10 settings — almost exact same for android devices — settings > wireless > top hidden options “Advanced” and choose for “keep wifi connected when:” — options are when screen is on, when connected to power, all the time. first or second by not third.
big boost right there — now to further smart settings, uninstall apps you don’t use (or plan on trying more like it) cause they do stuff on their own, online or offline even (which would wake cpu and start using power) .. android folks call it ‘wakelock’. and set some conservative settings elsewhere — syncronize everything to cloud services? word choices for keyboard? stock quotes? all that email?
hardware wise, lithium batteries lifespan is rated in complete charge-discharge cycles, and conveniently (chemically), works out that a half discharge, recharge, half dischage counts as one discharge =) several hundred at least. discharging below 30% takes more toll however, but don’t worry yet — what I would do is charge it full, and discharge to ~30 and charge full again, use plugged in for extending times — put power settings to do something aroun 30%, notice when it happens and put tablet down or charge soon .. all is well!
also — screen brightness. screen uses a looottttt of power. notice that when set to auto-adjust mode, the screen is bright in a bright room, and dimmer in a dark room. how many people have that thing turned all the way up at night?
November 15, 2017 at 5:44 pm #74895The battery in my iWork 8 Ultimate is crap and has been from the start. I originally bought the Windows 10 only version, and noticed that the battery seemed to be a rejected higher capacity, Windows read the design capacity much higher than the actual capacity. Whatever. But I flashed the ROM to the dual boot android+Windows ROM, and since then the battery only registers as charging up to about 70% where it stalls. But, before it calibrated to 70% max, it would show 100% charged but power itself off at ~30%.
So my guess is you just also have a crap battery and need to calibrate it. I recently ordered a 4000mAh battery to replace the original one, hoping it fixes my issue.

I don’t have this cube but I am interested in getting a battery myself. Do you have a source for batteries that you could link? Also, if you have any results you could post back, I’m sure many would appreciate your efforts. Thanks Johnm
November 16, 2017 at 3:27 am #74917The battery I bought is this one: https://www.aliexpress.com/item/Polymer-battery-9-inches-tablet-battery-domestic-the-built-in-rechargeable-battery-5000-mah-3976108-free/32614769136.html?spm=a2g0s.9042311.0.0.nUixwz
Model 3976108 5000mAh, should be a significant upgrade. Still waiting for it to come in. I anticipate having to do some basic soldering to hook it up, but otherwise based on the dimensions it should be a good fit. I’ll post my results once I get it installed. I’m also going to do some basic upgrading of the thermals so bought some thermal pads and copper plates also off aliexpress, I don’t push it too hard, though.

Thanks for this link. I really hope you’ll come back and let us know about your experience. I’ve never heard of anyone replacing a battery successfully. I have heard of attempts, but no success stories. Good Luck!
