Making the battery last MUCH longer

I still own an HP iPAQ. Granted it's getting on a bit but I can do everything the Orange SPV M2000 (Blue Angel) can, except make phone calls. It was a great little device and one of the best things about it was the battery lasted ages.
Granted it doesn't have to keep polling the radio signal every few seconds but there is one way I think that battery performace could be improved and that's by making the screen less bright.
Right now I find the screen is way too bright at night. I play games and read on it in bed.
Is there any way of programatically making the brightness levels finer grained? WM5 has 10 graduations whereas the iPAQ has about 30.
Through this one change alone, I know I could get about another 2/4 hours usage out of my Blue Angel.
Anyone (Helmi?) know if this is possible by simply increasing the number of divisions in the brightness slider?

Isn't this just a change of a variable in the code or does the hardware fundamentally not allow it?

Looking though the registry there is a reg value for the brigtness levels at..
HKEY_CURRENT_USERS/ControlPanel/Backligh/
[ACBrightNess] and [BrightNess]
At default, the maximum value of the BrightNess settings can be 10, the lowest 1, with any other number higher or lower apparently turning off the brightness. You can adjust the scale of the brightness levels, so you can have 30 diffrent levels of controll by editing the [DefaultACBrightNess] and [DefaultBrightNess] values to 30, but this doesn't work too well on my device and value 1 is just as bright as it was before.
One extra little thing though, is that on the same registery folder is a value [QKeyLedTimeout] which controls the timeout of the blue lights behind the slide out keyboard, in seconds. I've set this to 30 which seems to be better then the mear 10 seconds you are normally given.

Thanks for that Percz
I'm going to download a registry editor from somewhere and give it a shot.
Did you work all this out by playing around with the registry?

I found in the same folder
HKEY_CURRENT_USERS/ControlPanel/Backligh/
the two keys MaxACBrightness and MaxBrightness. I set those to 30 and now I've got 30 graduations in the slider but only the first 10 work.
I guess there must be another two keys somewhere that set the actual low brightness and high brightness values.
I'll keep digging around and see if I can find something.

Well I have a HP Jornada 720 Handheld PC and it is 6 years old and still has the original battery in it and I find it lasts about 7 hours easy and I use it every week or so now but before I would be using for a couple of hours a day and it just keeps going a reset every few months but other than that it is fine. With the BA reset it 3 times a day, carry a extra battery just so it makes it through the day and then you still have other problems.

Safe Temp Charging/GPS

have a Nexus one running Cyanogen and the UV UC Kernel from persian.
I do not have setcpu to run it overclocked but have setcpu to run at normal speed, and with prolonged use the temp can reach 94-98 degrees. Standby etc it runs upper 70's.
Problem I am having is that when I run it in my car using a car charger and with GPS running it quickly hits 99 degrees. Mind you that setcpu is under-clocked it to 763 while it is charging. I have my failsafe set to 98 degrees and it goes to ~650 but the temp still rises albeit slowly.
What is a dangerous temp for the phone? I have not had any adverse effects, but I believe with my 98 degree failsafe setting I am being very conservative.
Has anybody watched their temps while charging and using to see what temp you phone stabilized at? modded or un-modded?

Nearly 106. But now I've got an Air Vent holder for the phone and it stays pretty cool. Don't remember exactly what temp it was, but I believe that it stayed in the low 80s (with music playing on top of GPS & plugged in). Haven't used GPS lately.

+1 I did notice my battery was abnormally hot when I run GPS. My failsafe is 40C or about 100-102F... Usually over that FC's the Phone or makes it hang. At least my experience.

Thanks, I did notice this evening that my phone hung up after exciting Copilot a couple times. I could open up any icon on the home screen but it would not scroll, however the temp was only about 96 so I am wondering if it was more of a problem with co-pilot. I also ran pandora and copilot at home for over an hour hooked up to the computer and the temp only hit 91. The phone still gained positive charge but not very much. I might try getting a USB charger and slow charge in the car instead of the 1a car charger I am using now.

Temperature, Time of loading and unloading of the Gt-i9295

Hello, I am opening this thread since I read that some people experience problems with high temperatures or problems in loading and unloading the battery so I ask you to please share your usage statistics to check the normal statistics of our device.
Approximate charging time from 0% to 100% =
Approximate time of download in navigation, YouTube or chrome in mobile networks =
Normal temperatures in sets =
Normal temperatures in Internet browsing and normal use in mobile networks =
Normal cpu temperature in normal use =
And if possible specify the rom and bootloader you are using.
I am one of those who are experiencing problems so I want to know if it is normal or not, I expect their answers.
(Text translated by google)

yes its normal I have S4 Active for 4 years
and Installed many Rom
I think snapdragon 600 is the problem and gets hot very easily with normal internet use no matter how you change the settings
but I have two battery and they wont get hot when charging even with 2000 mah charger
___ by the way I use some cold heatsink when I share my free 4G internet using hotspot
It gets damn Hot downloading 3 Mbit/s
and eat my battery after 45 min
its much better when sharing the internet with usb tethering
and watching youtube .... no way it will burn after 15 minute
but the worst situation for me is hotspot never played a game on my s4 piano tiles long time ago
sorry I have no stats about cpu temp ... right now
Its a nice phone btw I wil use it as long as it works
graet standby time using the latest build from Tsvietkov

Does nokia 9 have a super accurate gps chip BCM47755?

The Broadcom® BCM47755 location hub is a single-chip device that combines location awareness capabilities with the typical functions of a sensor hub. The combination provides synergistic benefits that cannot be achieved with multiple ICs, such as low power consumption, higher accuracy, reduced footprint and a smaller BOM.
The BCM47755 supports two frequencies (L1+L5), and as a result, achieves lane-level accuracy outdoors and much higher resistance to multipath and reflected signals in urban scenarios, as well as higher interference and jamming immunity.
Furthermore, the BCM47755 incorporates numerous technologies that enable ultralow power consumption in both the location function and the sensor hub function. The device features a low-power RF path, a Big/Little CPU configuration composed of an ARM-based 32-bit Cortex-M4F (CM4), an ARM-based Cortex-M0 (CM0), and is built in a 28 nm process.

I comment on real life performance. I cycle 5 miles to and from work and use Strava to track my ride.
The time between opening Strava and getting a lock on my position is insanely quick. Pretty much instant.
Also, on other phones GPS tracking would to sap my battery. With these activities and typical usage throughout the day I have only gone through 30% of the battery. Took it off charge 15 hours ago.

NIBE (heat pump) automation

Hi
Is it possible that Tasker can monitor when the hot water comes to a certain temperature?
If you're not familiar with the NIBE heat pumps they allow you to control the system remotely via an app. Here you can see the status of the hot water temperature and if I can somehow get Tasker to watch this figure and when it hits 52c it will notify me on my Google speaker.
