Where is your battery indicator coming from? Standard OS, or have you tried 3rd party ones as well?
What does it show in settings > power?

ok, please send me a url to download this program, however i think this will not solve the problem, but i will try, also please tell me how to backup the extended rom incase that i try to install another rom version, if that may solve the problem
B.Regards
i made a backup of the extended rom, and installed the latest rom available here for the magician, same version number as my old one, and still nothing, battery indicator show 100% and doesnt move
sounds to me like an internel fault of the phone... possibly some grit has entered the phone and damaged the votage sensing cercuit.
Also (not sure about this phone), some devices have a smart battery where there is a small pcb inside it that reports to the phone the batteries serial no, charge level and other ACPI type info. If this is the case, you might try a new battery, it may fix it
Someone correct the above if they know the battery does not contain anything but... well a battery.
Hi all,
I'm looking for some battery testing software as I need to grab logs for a range of PPC/W5/W6 devices, I'm after basically battery status reading every 30 mins. I need to be able to get the data from 100% to 0% and the time.
Preferably this would work externally via a usb to a PC as the devices come installed with our own proprietry system that restricts some of the functions that come as standard.
If anyone has any suggestions I'd be very grateful.
Many thanks
Ben
Hello,
the forum rules do not allow to post in "Development" section, so I am posting here.
I've installed CM 7.2 ROM for ChaCha from this Thread. (Build date: 20120824).
After reboot everything looked normal, there were minor lags, but since this was my first custom ROM, I assumed that it could be related to my performance settings (Governor: conservative CPU: 245 - 800Mhz). I've switched off all data connections (gps, mobile network, wifi) and disabled all animations to see how much battery it will consume in first 24 hours. To my surprise, the phone was off and battery was completely empty in the next morning.
I've installed CPU+Temp system widget to monitor CPU load. The widget showed that on idle system CPU usage was 98%-100% on maximum allowed frequency. After reboot the idle system CPU was normal - 1-10% on 245Mhz. Then I switched on Wifi and noticed that CPUusage started to increase. I've disabled wifi but CPU usage was up to maximum and didn't drop until reboot. I found that the same problem occurs with mobile network connection.
I opened Terminal and typed "top -m 6" to see which process is using the CPU. I found that system_server.so was taking up to 90% of CPU when the problem occured. "top -m 6 -t" showed that GPSLocationProvider thread of system_server.so was using all the CPU, in despite that GPS was always off.
I've started to search the solution of this problem and found this thread, which described that the problem is that librpc.so is not compatible with HTC gps drivers.
Then I've tried SuperOSR ROM and CM9 ROM. Both did not have this problem, which was interesting since SuperOSR is very similar to CM7.2. I've returned to CM7.2 and tried to solve the problem.
I updated the HTC drivers to the latest level (gps.chacha.so and others from the latest stock rom), but it did not affected the problem.
Then I did the binary compare of /lib/*.so between CM7.2 and SuperOSR and found that just a few libs was different. One of them was above mentioned librpc.so. I've installed librpc.so from SuperOSR to CM7.2 and the problem was gone.
The CPU usage now is 0%-4% when system is idle.
I hope that it will help others which is affected by this problem and I also wish that this bug could be solved in CM7.2.
can we use this metode for CM9?
HTC Chacha with CM9
This problem is not reproduceable on CM9 on my device. I believe you have different problem with similar symptoms. If you are experiencing 100% CPU load on idle device, open terminal and run "top -m 6" to find which process is using CPU and "top -m 6 -t" to find specific thread.
More likely you are running some widget which causes hang.
Thanks for the info! CPU usage was fixed to %100 before I did what you said! Thanks again :cyclops:
Hey, guys recently updated my opo to cm12 official.
Android system is draining a lot of battery ,around 20-25% on every charge cycle.
Some service or app is keeping CPU awake.
Anyone else facing this issue ? Any help or fix ??
Exactly the same problem!
I'm trying to find a solution but with system i don't know what can be done..
I have another issue draining my battery: the mobile radio active in some apps (Chrome and Facebook in my own phone) and I'm trying to understand if they are linked
I did some research, and I have not seen anyone report this. It has come to my attention that the Android 11 beta DESTROYS my watch battery. Maybe it communicates a lot with the device, but it always drains so quickly.
I saw in a different forum (completely different website...not sure where at this point) that someone who owns a Mi device running on Android 11 has the same problems. It seems like this is a problem with OS 11 and not our device specifically. I have observed from the beta that my watch vibrates a LOT more, and I do believe that the phone is pushing all notifications and alerts to the watch, including those that don't need to be pushed over. Every time I connect my Bullets Wireless 2, I get a dismissible notification stating that my device also supports aptX. EVERY TIME. This notification cannot be edited or blocked. There's probably a lot more of these kinds of communication between wearable and phone going on in the background.
Currently, I reverted back to Android 10, and all is well once again.
