Hi,
I have a GSM version of Raphael.
Since day one I've had quite short battery life of the phone - something between 24 to 36 hours (including standby and very moderate use).
In an attempt to find out the reason, I've installed a few programs which monitor the phone's current consumption, battery voltage etc.
Making long story short - all programs indicate that the phone's current consumption is ~56-60mA in standby mode. Thus, 1350mAh battery should last for 1350/60 = 24h.
That far everything makes sense. However, I've looked for methods to reduce the current consumption, either by downclocking the CPU, by turning off all radios, removing all skins and programs running in normal mode etc.
No luck - the current consumption just won't move.
It doesn't make much sense that turning off all radios, turning off the screen, turning off all programs etc. won't reduce the power consumption by even a fraction (depending on the SW/HW metering ability, of course).
Another strange behavior of the battery is that the battery indicator does not change for quite some time, and then drops by 3-4% in a very short time (~1 minute). I've seen this phenomenon in several monitoring programs, regardless of the updating time of the program.
Has anyone figured a way to reduce power consumption in standby mode?
What about downclocking?
Does anyone know what is the current consumption on other longer lasting battery time HTC phones?
Yuval.
disabling 3G normally saves battery.
did you make tests while in 3G or 2G?
I would like my battery to last longer.
FYI- I dont need a monitoring program to tell me that wifi, data, and bluetooth visibility kill my battery...
Battery test conditions
Note that the 56mA current consumption is with all radios closed!! (alternatively only with 2G GSM on - no 3G, no WiFi and no BT).
The point is to reduce the amount of current drawn from the battery in standby mode.

Do you have the nuePower battery driver? I've heard that its not very accurate.
It's weird that you are looking for a way to extend the battery life as it is clearly stated that the battery lasts for about up to 419 minutes of talk time (about 7 hours). So, no matter what you do, that is the maximum. Please note that the 7 hours does not included standby time. Regarding standby mode, no use to play around with it as if you put your device in standby mode, it will last 367 hours. Of course, without even waking it up even for a moment (after a full recharge).
Running battery monitoring program normally makes thing worse as some do not allow the device to truely enter standby mode. Also, note that some 3rd party applications also cause that, for example S2U2 (version 1.40 seems to fix the problem). Plugging in the earphone (via the usb port) also does not let the device to truely enter standby mode. The easiest way to test is to play some music and press the power button. If the screen turns off and the music stops, then it is in standby mode. If not, then the device is does not truely enter standby mode, and it consumes power (but lesser than when it is awakes).
In other words, no matter what you do, the battery lasts 7 hours of usage. So, the only way to extend the battery life to is purchase an extended battery (1800mAH) for Touch Pro. It will make your device thicker though.
When all the lab/field tests are done, one of the tests is to measure voltage drop with a Scopemeter/power analyzer. All we did was put the STOCK device in standby, took the back cover off and measured voltage draw with a Scopemeter/power analyzer . That would be the most accurate means of testing. The Scopemeter I use is a fluke 225c. With a Fluke 43b power quality recorder. the max over a 36hr period in standby was a 24.9mh draw. the lowest recorded was 12.1mh draw. The average was 19.3mh. You could also do this with a basic DMM.
I should also note this was done with ALL radios off.

How would I find out which battery driver I have and also what alternatives are available?
Hey guys so I know there are a few things that can improve battery life and some things that are supposed to help but may be a mith? Things as only draining battery to 10% and charging to 90% or something like this. What are tips that help? Also if you guys have changed your cpu settings that really improved the battery life let us know!
I drained my battery down to 0% after the second time I used it and it pushed my battery up from 3:30 to 5:30. I also use batterybar to see the stats and whatnot. Another thing you can do is go into power options in the Control Panel and change the plan settings > advance power settings. I usually change the Processor power management settings and the Intel Graphics Settings.

do you ever charge it to 100%
Does leaving it on the charger like when playing a game or something matter? Does it stop charging once it reaches 100
AFAIK, leaving it on the charger shouldn't matter. It's a smart charger. I always charge it to 100%, but never go lower than 10%. I try to recharge around 15%.
Best thing I've done is disable my bluetooth since I have no devices that use it.
Second is lower the brightness while on battery.
I'm getting around 5:30 of battery life doing things like browsing, email, news reading, and using Autodesk Sketchbook Design.
Disable automatic brightness. Change the screen timeout to the lowest value that works for you. Turn off BT. Turn off live tiles and notifications for apps you don't need to update on your main screen and lock screen. Run the troubleshooter for power and see if you can deal with what it changes.
Battery Saver HD provides the best features to saves the battery time of your phone or your tablet. Whenever battery runs low or goes too much down then just tap the application to turn on the saving mode.

Soo! again with another battery post..
Okay i followed some rules someone helped me with the other day in regards to resetting the whole phone and updating it, which i did and the battery was fixed! now untill about 2pm to day my phone was lasting all day i mean since 8am it went from 100% to around 70% and said i had like atleast 1 day with stamina mode on..
Now its at 65% its telling me i have 4 hours remaining without stamina mode and now 11 hours with stamina mode..
Can someone explain why to me? i mean i don't think i have loads of things on that are heavy on battery life.
have you looked at the battery stats to see whats eating the battery?

Mainly the screen, i noticed tho soon as i had to use my phone to be a satnav on google maps it enabled high active location settings, but after i finished i turn the location settings back to battery saver mode so i cant see why it hasn't changed the battery daily span, i mean the screen is the biggest consumer at 29% then snapchat at 15% then some more social media but there below 14%
gps and using it as a sat nav will use the battery quite a bit as the screen is always on, try turning the brightness down
I just, cleared the date and cache on my stamina mode and reset the phone and it seems to have fixed it, i will apparently get 4 days and 11 hours out of my stamina mode now on 96% battery. i have adaptive brightness on tho btw, so i'll just turn it off and lower my screen too

There is a bug in the Stamina Mode statistics. They will only work for the first day and then start showing the wrong time remaining, but don't worry about it. Although the time remaining is wrong, Stamina mode should still be working. You can test this by allowing the phone to sleep for 30min when connected to wifi and then wake the phone to see if wifi is still enabled. If the wifi icon is not showing, but then pops up shortly after waking the phone, then Stamina Mode is working.
Hi
Since several weeks my galaxy s6 has been suffering severe battery issues:
- average drain per hour is 10%
- average screen on time is 2h spread on 12h going from 100% -> 0%
Analysis:
- no real app drain
- phone signal is OK/high
- Google now is off but all the rest is on (data/wifi/Bluetooth/location settings...)
- Gsam reports show that my phone never goes into doze mode... It suffers from really bad standby time
I tried a factory reset, battery calibration, package Disabler etcbut nothing helps.
Sometimes when my battery is nearly dead at around 5%, it jumps to 10-20% when plugging in. It seems that something is keeping the phone awake all the time.
Can anyone help? Images from Gsam are attached.

The battery jump is indicative of a dying cell. It might be time to have the battery replaced..

Turn off automatic backup and restore in your device settings, worked for me (if you want to use the restore function just back it up manually). I have read somewhere there is an issue with the google backup transport service in 6.0.1. I don't know if the samsung backup has the same effect, I turned it off, just to be sure. Before I got like -3.8% battery decline per hour and now it's like -0.8% per hour.
