Has anyone managed to get 2-10 mAh power consumption?

[Guntherm]

Anyone get to usage mA out of the program. The graphs tell you alot, but always has negative numbers in it, so you can't seem to monitor what its at very well.

With just root i used to run 26-42 mA
Virus Rom 40-80 mA. mostly 80's.

that current draw can't be accurate if it puts wifi and 3g on par with each other. I get full bars of evdo at my house and wifi gives me easily 2x the battery life of 3g. I wouldn't trust android to tell you how much battery drain is happening. need real-world tests.

I have found another battery thief: Animated Weather. It's very nice but seems to drain battery (it did that last time I tried it on my HD2 in October 2010 but I thought it had got better). I installed it yesterday but the drain immediately increased to approx 90 mA too often despite weather syncing every 4 hours.

The lowest value I has ever seen on the Thunderbolt is 24 mA but now it's back to 30-40 again. I have decided to give the Das BAMF 1.3.1 a try - it seems like it solves different bugs with the 1.3.

My observations when I compare to the HD2 is normal power consumption while in use, in some cases lower BUT the standby drain is way too high. I have a very similar configuration on my HD2 running the same apps, the main difference is the networks (T-Mobile 1900 vs Verizon LTE 700). The fact that airplane mode isn't solving the drain issue is a very strong indication that something (radio perhaps) is causing the drain. It looks like we need an update of that part.

The ROM and kernel parts are fixed I think and I can't see any reason for drain from those areas. It drains even if the CPU is underclocked to max etc so I think the radio is the root cause for this.

How is the radio to blame when airplane mode completely disables all radios and drain is still high while in airplane mode?

 

[Guntherm]

Well I solved part of my draw on my precious...

Using some different clocks I took out the retrieving temp off the clock widget(was set for every 2 hours). Downloaded weather bug elite and set it to display temp in the task bar, no widget and wow. Down to always 24-32 when idle. And this is with the Rom Virus... Now if I could get another 6-10 mA out of it....

I tried turning off 4G leaving 3G on only and at least during overnight/unplugged idle it helped. The consumption draw looked about the same 30-50 mA range, but the total overnight drain improved a lot (I know seems contradictory but I did not do an average of the draw figures - the consumption should be that figure, more or less). Disabling 4G bought me about a 50% reduction in total battery drop overnight/unplugged, down from about 15% to about 10%.

Disabling 4G is done by:

dial *#*#4636#*#*
Phone information
Set perferred network type: CDMA auto (PRL)

note 1: default is CDMA + LTE/EvDo auto)
note 2: 4G turns back on after reboot

Pet peeve of the day: mA refers to current, mAh refers to current * time (charge). Assuming a relatively constant voltage this can be viewed as power. A 1400 mAh battery stores enough power to supply 14 amps for one hour or 1 amp for 14 hours or however you want to slice it. Referring to a power consumption rate as mAh grinds my gears. That is all.

Not quite. The "m" in front of "mAH" stands for "milli", one one-thousandth, or 10^-3. 1400mAH = 1.4AH or 1.4 amps for an hour, 140mA for 10 hours, etc. If it were 14 Amp-hours (14000mAH), you'd pretty much be able to run it fullbore for >24 hours before it needed a recharge.

It's worth noting that with all battery chemistries greater discharge rates reduce the useful capacity of the battery. Depleting a 1400mAH rated battery at 1400mA would extract considerably less than 1400mAH (1000mAH might be pretty optimistic). On the other hand, depleting it at an extremely low rate below discharge rate used for rating purposes (let's say 20mA) might realize better than 1400mAH. If you ever discharge lead-acid batteries at a high rate (such as in UPS systems), you quickly learn that their faceplate ratings are typically based on a 30-hour discharge rate and you'll be lucky to realize half of their rated capacity running them down over 1-2 hours.

There is a new app in the market that does this now...

Yes a great app that automated the first step of the process but not the second...

Higher is better right

I was able to get my my phone to discharge at a rate of 878 mA. lol

Screen @ full brightness, pandora over 3g, bluetooth and recording 720p video. Im sure i could obtain a higher current draw but at this rate a fully charged battery would die in less than 2 hours. With the Tbolt, its possible to crush your battery but with power management tweaking and moderate (my normal) usage my battery lasts more than 16 hours.

Das Bamf 1.3.2 (default kernel)

 

[htowngator]

Mine still sips around 34mA with 3G, but the idle use is far, far less.

For example, I am at 75% and well over 4 1/2 hours use. Normally I'd be down around 55%.

 

[OlderThanDirt]

Thanx! Was bugging me too.

 

[OlderThanDirt]

Newbie needs help.
I installed CurrentWidget on my T'bolt, but I'm not seeing any readings.
I set up the log file to the default, but when I click View Log it says it can't find the file.

 

[turneja6535]

htowngtr, curious what kernel you are running, any setcpu settings? what governor? I'm assuming you have always on data turned off and that's while it "sips" less at times?

Anyone else getting better idle, screen off mah draw then him? What are your settings?

Thanks

Can someone who is rooted and does CPU speed management while the screen is off post up some idle consumptions? A lot to ask I guess... We really need to get down to at least 10-20 mA consumption while idle for any chance of significant time away from charger.

 

[turneja6535]

I am getting 38ma at idle with screen off 3g connected. I was getting 24ma with all radios turned off so not sure what it would take to get to 10-20.

 

[Guntherm]

The lowest I can get is 34 mA

 

[paulmike3]

I've seen 32 mA on mine, but usually 38 mA.

 

[turneja6535]

Yeah mine seems to settle down between 30 and 38, went with the conservative number. Running Imoseyon's 1.4 lean kernel and stock rom (debloated). Using the conservative governor, getting around 16 hours now with my use. Was getting 4-5 on stock.

Im rooted with setcpu. Not much difference honestly. I still get 34 to 38 as my low idle draws, but it doesn't stay at that current when idling. It fluctuates from the low values to 90mA comsistantly and I can't figure out why.
