How To Fix BlackBerry Z10 Battery Dies At 30-15% 1

Although the Z10 has a removable 1,800mAh battery, there are some few minor issues with this battery that users are facing. Recently, I have gotten a complaint by a Blackberry user, stating that every time his Blackberry is at 25% the phone would automatically shut off. While some people may conclude that it’s some software or update issues, well it’s not.

I have just recently bought a blackberry z10,its less than two months old but surprisingly it cannot run with its battery level at/below 25%,i dnt get warning signs for low battery anymore,it just switches off,what could be the problem?


There are several reasons why your blackberry Z10 Turn off at 30-15%. One of the reasons is security wipes. Security wipes should be taken keenly with precautions because when a user updates his Blackberry and performs a security wipe it affects the calibration sensor,  thus causes the battery to die at a low percentage.

Battery Re-Calibration -Fix Z10 Battery Dies at 30-15%

By re-calibrating your Blackberry Z10 battery it will restore its full potential and capacity.

Source Wikipedia

If overheated or overcharged, Li-ion batteries may suffer thermal runaway and cell rupture. In extreme cases this can lead to combustion. Deep discharge may short-circuit the cell, in which case recharging would be unsafe. To reduce these risks, Lithium-ion battery packs contain fail-safe circuitry that shuts down the battery when its voltage is outside the safe range of 3–4.2 V per cell. When stored for long periods the small current draw of the protection circuitry itself may drain the battery below its shut down voltage; normal chargers are then ineffective. Many types of lithium-ion cell cannot be charged safely below 0°C


By Preforming a full Re-Calibration, it will make your blackberry Z10 battery more accurate. Following are the steps for that:

  • Remove the battery from your Blackberry 
    Remove battery
  • Plug in original charger into your blackberry without the battery inserted, VIA PC. Do not connect it to the wall socket 
  • Leave it there plugged in for 30 minutes
  • After that insert the battery without removing the charger
  • Let the blackberry charge to 100% 
    Battery charge 100%
  • When the battery is fully charged remove the charger
  • Let your Z10 drains to 0%(Discharge) ( Do intensive CPU usage tasks, Play games, stream videos etc.)
  • Repeat these steps twice
  • The battery will subsequently receive it’s charging cycle
  • By performing this  3 times  in every 6 months, will keep your battery in good standing. 


  1. my z10 drop down in water, i instant remove battery then i wipe water through dryer next day i put the battery in my phone and its work, but after 2 week battery backup getting too low and now if charger unplug mobile instant off. please sum idea or advise for the same.

  2. good tip, i have followed the same and succeeded. but at 25 % battery it is going to shut down

  3. i also had severe sudden battery drain problem in my Z10 which is less than a year old. i have solved this problem by :- go to device manager, check what applications are sucking battery most and then customize them. i checked the same way and found that BBM is taking the entire battery almost whereas I am not using BBM at all. I tried to deactivate BBM but could not succeed. Then i went :- settings –> security and privacy –> parental control –> set your password and then you will find that it is disabled, until you will set the password, you will not be able to ON it, once you on it, you will be able to customize all the features of different applications including BBM. i could deactivate BBM from here alongwith customization of otherfeatures as per my requirement and after that the battery drain problem resolved. Now i am using my phone comfortably for entire day and by evening still i remained with above 20% battery. I am using two google accounts alongwith all other features like, twitter, facbook, evernote etc. Hope everybody will be benefitted with this input.

  4. thank u sooooooo much for a wonderful tip..
    i was just fed up of battery issue and thinking to drop my cell phone in dustbin..
    after i tried your trick, battery lasts till 0% and backup is also increased…
    with best wishes, thanks a lot….
