Hi everyone,
i realized that battery consumption on my g2 mini is mainly due to 2g/3g/4g signal/data connectivity. I am not saying that battery is terrible, but given the capacity and screen PPI, it should give more autonomy. I did some research and found a lot of stuff about WakeLocks, but thats just tiny part i guess. I think that the most battery hungry is radio antenna while searching/switching between towers.
So the question is, is there a way to optimize signal search/switch? Thanks

I was thinking that a possibility we have battery life and reception issues is because our phone does not know how/when to properly boost signal strength. I think it boosts it to soon because you can go from 1 bar 3g to full edge almost instantaneously, which to me looks like the phone feels the signal is getting low and boosts it to high instead of giving it a little more time to adjust or boosting signal a little more, not alot more. Also this has me thinking that our phone does this constantly while sleeping too causing battery life to decrease significantly. So quesion is, can we control the signal boost on the phone?
So I'm constantly walking into areas where I have no signal at my school. The result is an increased drain in my battery in these low signal areas.
This is a problem that I have noticed on all roms. Radios also seem to have little effect besides changing some current draw bound (ie -4 to -9).
I use radio 2.14.50.04.
when I have signal (guesstimates)
In standby idling between -2 to -6 ma
30% Brightness Screen idling, -100 to -150ma
however when I have no signal current draw increases to -80ma and higher and doesn't go down until I'm in an area with signal.
This would result in a standby time of only ~15 hours.
When compared to my standby time of -2 to -6.... at the least would provide a standby time of 205 hours.
Are other people getting the similar results under the same conditions?
I use tBattery to log my data.
Oh and I'm currently using Energy Sencity Rom with Cookie 2.0 Final (november 19) if anyone is interested.
My soft reset button is red
I have a TMOUS branded HD2
It just seems unreasonable that my phone should continue polling for signal for 2 hours and drain 20% of its battery during class...
Perhaps someone has a reg tweak for this?
post tBattery logs if you can and state conditions for changes in current draw.
edit:
perhaps its not clear what my question is from this post...
Is there a fix to substantially decrease battery drain when the HD2 has no signal (airplane mode doesn't count )
iPhone seems to have got it down....
bump
Are other people experiencing this issue?
Same happens here with TMobile US HD2. I disabled Sense and that helps with battery life, but I'm curious to find a solution. Tried wmlonglife and band switch, but wasn't happy with either.
tried that as well
I have also tried WMLonglife and CMBandSwitch as well, didn't really solve my issue...
wmlonglife helped a little, but it was still kinda unpredictable, sometimes it would work.... it doesn't actually solve the problem of signal searching....
also, I think this happens 90% of the time, not *all* the time... sometimes, after being in an area with low signal, my tbattery may show a reading of -7....
I'm not sure if the registry has a way to fix this....could be radio related.
bump
i think it is okay to bump this....
I get the most battery drain in a building when I have no signal.
Other than that, outside or in my house the power consumption is very good (2-7ma)
*i get 80-130ma consumption in buildings...
I wish there was a way to decrease the increased power the antenna was using as well as increase the length of the interval the hd2 uses to search for signal....
that way, the power consumption would be close to the same in buildings with low signal as compared to areas with excellent signal....
really would like to get this resolved without having to swap out batteries.... Only problem left for me. Many other phones when they don't have signal don't seem to be affected greatly with this *cough cough* iphone....
ive noticed this too. when there is no signal the battery drains much faster, also happens if its continually switching between a good 2g and poor 3g signal.
i often just disable the phone until move back to a good area
would be great to have a fix... even it just gives up trying to get a signal after a period of time
It has been documented that using wifi when at home (for example) can conserve battery, however in most cases there is a stable GSM signal. For this reason the phone will not waste a lot of battery trying to connect to the cellular network over and over again. However, I have an unusual situation that I would like advice on. My office has TERRIBLE reception and in fact I constantly lose/regain signal all day long. I believe this contributes to relatively low battery life on my phone(s) that I use. We do have office wifi however, and I am wondering how connecting to it will impact my battery. Would that improve the battery drain, or would it actually make it worse?
Hi all!
When I'm at home, I get about 3 bars of 3G signal. I have had this phone for about 3 days and the battery life is really bad, using basic apps drains my battery really fast. Should I change the network to 2G? Does the poor 3G signal affect the battery life significantly?
Much appreciated!
If 2G is enough for you, change it. It uses less battery even with good 3G signal...
And yes, a poor signal always uses much more battery life than good signal, no matter GSM/2G/3G/4G...
Yes, I have noticed that in areas where signal is poor (1-2 bars), battery drains significantly faster. It's quite irritating since this issue is non-existent on iPhones. I wonder if a software update can fix this.

It's the technique of every phone, even on iPhones... the amount sure can vary, but it's not inexistent...
I have about 1-2 bars at home and over night it takes about 2-3% of charge, very similar like iPhone I had before...
it does on mine. at work i get full signal and though i use it a fair bit, it doesnt seem to use too much battery but at home where i get terrible battery life it seems to use more battery
Let's say all things equal, which would drain the phone battery the most - being on WiFi or on LTE?
I know on older phones LTE round drain the battery like I drain a glass of beer, but I'd imagine the chips are much more efficient now than they were back then. Is one more battery efficient than the other?
Phones are still designed to use WiFi if possible when both WiFi and data are available and this behavior is independent of any data saver settings you might use so it's a pretty safe bet that 4G still uses more power.
