I would like to start a BlackBerry 10 battery life challenge. I have seen many threads of people discussing battery life performance and posting screenshots of their Device Monitor. The majority of these screenshots do not show a full discharge cycle which is not representative, they show performance after a few % discharged; also people seem to focus a lot on the battery time remaining number.

The battery time remaining information needs to be better understood. I have seen many people using this value to praise or criticize battery life performance. There is no such thing as heavy user or light user, there are moments of heavy use and light use of your device throughout the discharge life cycle. Please understand that your BlackBerry 10 device cannot predict the future device use. Therefore Device Monitor uses your past activities in the past 30-60 min to calculate the average drain rate of your device in order to estimate the remaining time left should you continue using your device in the same way. If your device was in standby or in light use, Device Monitor will estimate a pretty good battery time remaining number, but if you device was in heavy use, such as playing a game, Device Monitor will estimate a low battery time remaining number.

Having said that, true battery life performance is measured in how long your battery last since the last charge. I have also seen many users complaining about battery life, but they never let their device fully discharge. People, sometimes for valid reasons, charge their device when battery levels reach 20%-40%. You will be amazed by how long your device can still last with 20% remaining.
When it comes to battery life performance, there are three major components that consume power on your device: Screen, CPU and Radio (mainly cellular radio). If you want to be in charge of your battery your need to properly manage these resources and understand their impact on battery life. Sometimes bad designed applications do not properly manage these resources resulting in poor battery life.

Battery Life Challenge:

What I and, I bet many other BlackBerry users, are interested is in the real battery life performance of our devices. So my challenge to you, should you accept, is to:
Step 1: Charge your device to 100%
Step 2: Let your device discharge to at 5%. Use your device as you normally would between steps 1 and 2.
Step 3: When you reach 5%, collect the following information and post on this thread:

• Device Model
• Build Number
• Display Brightness Level
• Screen shots
  
• Battery Usage List � Since last charge
• Battery Usage Details of the top 3 apps
• CPU Usage List � Last 48 hours

I'm willing to give this a go, but I'm not sure if my results will spoil the test - I use a Dev Alpha B as my daily driver, and the fact that it only has 1GB RAM may skew CPU usage somewhat...

Here is my information:

Device Model: Z30
Build Number: 1925
Display Brightness Level: 50%

Screen shots
Battery Usage List – Since last charge


Battery Usage Details of the top 3 apps


CPU Usage List – Last 48 hours

Ok....i will run mine right down. however, using smart phones for years now, and everyone I know has one, the z10 and iphone are comparable, the z30 leaves them all in the dust.

In fact check out the 48 hour usage. This phone will never die in a day of good use. Notice I used the device from the morning till the early hours of the next day. Still 25 percent left.....i use my device constantly.....i had to recharge before it. So beat that iphone lovers.
