Using BlackBerry Device Analyzer, what is your typical "Battery Drain Rate" per hour for your 9900?

[maxx71]

Less than 1% when idle or little use but normally somewhere around 4% thereabouts.

You should have 0.00-0.99% put into your poll

Also I would like to mention that if you use auto on/off you don't get the correct numbers.

It looks like when charged it will also show a too good (less) usage.

But after a long fight with apps and OS versions I am down to 1-2% idle (7.1.0.569). On a 7.0.0.5xx idle was 7-9% !

One full hour browsing/texting drains 9-10%. Extreme usage like camera app open, 7-9 tabs+ open, and social fees + wifi+3G and bad network 15%

Worst ever: wikitudes over 20% with an older (less good idle)

It's not that simple with typically drain

i was very attentive to battery life when i first updated to 7.1. on an average drain is 3% and that is with moderate use. when im using the remote it bumps up, but my phone is always bridged and wifi is on.

I'm a heavy BB user, with Bluetooth on 24/7, bridge on much of the time. But, I still hover in the 2.1 to 2.6 ADR range. Gotta love the BerryLicio.us Ultimate hybrid! That team does a great job. My device has never run so smoothly. ~ecm

I use to watch my drain rate constantly. Then I stopped caring about. Why worry? My device last all day, plus I have an extra battery. I only keep an eye on it for a short amount of time after an OS change.

What is typical? Typical idling is under 1%. Typical non-idling is much more, but depends on what I'm doing (e.g., google maps, email, camera, phone call).

Idle should be around 1 or less. Non-idle can be anywhere from 3-7 or greater depending on what you're doing.

The problem with the drain rate is, if like me you charge your phone overnight, you will have a few hours where it is 100% battery and 0% drain rate when it is plugged in. Taking the whole day average drain rate then takes into account your several hours with 0% drain which isn't a true rate and makes it seem better than it really is. If I look per hour it's generally around 5% considering I'm a heavy user. Idle it will go down less than 1% per hour.

Drain rate is measured OFF charger, not while it's plugged in and charging. It is the rate of drain by milliamp hours - regardless of what one is doing on the device. If you use a lot of radio/ apps and screen etc, the rate will go up...so average drain rate can and will vary widely by user. You could go to < 1% or you could be at > 10%. It depends on how one uses their device. Social feeds that update constantly will eat the battery...100% backlight timing out after 60 seconds will cause the device to drain off the richter scale...so there are a lot of determining factors. You can't compare one user against the next, unless you also break down each instance of CPU/ Screen usage as well.

And for those note liking this explanation, drain rate should be measured like fuel consumption in vehicles - only when being used, and everybody drives differently. Literally, your mileage may vary.

My number, 3.67%, reflects Bridge and Wi-Fi being on all the time.
