Review: The One v4.7.1 Battery Life

I like to start this new catergory "Review" on my blog, with my own product:
"The One v4.7.1" CFW for the Nokia N8

Something I get asked a lot about my CFW is battery life.
Many people are not happy with the N8's battery life, so I decided to write a review about the N8's battery life performance with my latest custom firmware v4.7.1 (the results should be similar for all my cfw's (since v4.4.0)).

Of course I already tooked a deeper look at the battery life of my CFW while I was creating/testing it, but I never published details about it... so here are the results of my tests, for everyone to read.

Phone configuration:
-dark theme (d0rsh v2, built in in my CFW)
-dark wallpapers (default wallpapers "the one")
-screensaver "nokia sleeping screen"
  -basic clock only
  -night mode from 20:00-08:00
-50% display brightness
-mobile data on
  -2g mode
-bluetooth off
-wlan on
-sync mails from 08:00 -23:00 every hour

Note: Those are my default settings I use every day, if you want to improve your battery life too, you  may try some of those on your mobile phone.
My best advice is, when you are not using the mobile internet connection, switch to 2g mode. Switching back to 3g when using it, is a matter of seconds thanks to the 3g/2g toggle widget!

Phone usage:
I was trying to keep my phone in standby and not use it, if not necessary.
During the testing period the phone was used for a few text messages and emails only.

I tested the battery life for 24 hours, the results I got are based on informations by "Nokia Battery Monitor v3".

I guess this screenshot pretty much speaks for itself:

As you can see, after one day of low usage I only lost 14% battery life.
Doing the math I get almost 7 days battery life with one full charge!
(24h = 14% = 0.6% per hour = 166h for a full charge (= almost 7 days)) Correct me if I am wrong ;)

Keep in mind that I was almost not using my phone, so this is more or less the "Standby/very low usage" time.

For my personal, regular usage (doing a few calls, email, txt messages and use the webbrowser for small stuff like sport results, tv guide, etc.), I end up charging my phone every second night.
(On regular usage I lose about 20-35% every day)

So compared to the original firmware where I had to charge my phone every night, I clearly see an improvement in my CFW.

But something I cannot change is the high power consumption, when using apps and widgets that require constant internet connection... use those apps with care, or you end up with a dead battery very soon.

I hope you like my first review ;)

Now its your turn:
  -what do you think about battery life of your phone or my CFW?
  -critics on this post are also very welcome (what is missing, what can I do better)?
