    Hello. I recently bought a brand new cubot x9. Everything seems to be working smoothly except one major thing. The battery is draining unbelievably fast. I fully charge the phone, I take it off the charger and then about 30 minutes later it's at 80% battery. Battery usage statistics are as follows:
    1. Cell standby - 28%
    2. Wi-Fi - 26%
    3. Phone idle - 19% (???)
    4. Screen - 8% (brightness is at the minimum value)
    5. Android System - 6%
    6. Dialer - 4% (made 2 phone calls, around 2 minutes each)
    7. Voice calls - 3% (what's the difference with #6?)
    8. Blade Master - 3% (some game I played for about 3 minutes)

    I am certain other people are having similar problems. I've read more than a couple threads in android central, but I didn't find someone with such a big problem.
    Thank you in advance. Any kind of help would be greatly appreciated.

    The stats are fairly meaningless without usage time and screen-on time.

    Use the device normally, then before you need to recharge, make a screenshot of your battery usage stats. Tap the graph to open it, and make a screenshot of that too, showing the signal and awakes history since last unplugging. Post the screenshots here. Tell us also your screen-on time, and brightness setting. From all that, we'll attempt a diagnosis.

    You too? In my case, just picked up a Cubot Note S (so far, so great), and while not as bad as yours, you can practically watch the battery level drop. This wouldn't be notable, ifn it didn't have a bigger battery than my last phone and I'm using both the same. I think Cubot is aware of the problem as they include Cleanmaster now, which amongst other things claims it can optimize your battery, but I haven't tried that yet, I'm always suspicious of such claims. I'll let you know ifn I find a reason/ solution.

    I am having the same issue with a Cubot X9.

    I have contacted Cubot and they said " Buy a new battery and see if that helps". Not at all helpful.

    After 3 days of usage, my Cubot Note S batery drains within less then 5 hours. And that is with average usage.

    Gonna resell it soon

    Obviously some cheap Chinese batteries. Better find replacement ones made by some reputable company. I had some experience with crap batteries in the past. If the battery is inflated, the stop using it immediately in order to prevent galaxy note 7 style fires.
