[Q] battery drain on gsm signal

hi all
recently i have just calibrate my battery.. and it works just fine
but now i found that it drains alot quicker using 3g signal compared to wifi...
the drain rate can take 10% /hour on 3g and only 4% / hour for wifi
why is that ?
is there something wrong on my gsm ?
btw am using leedroid froyo 2.0c and using latest radio 32.47.xxx
pls some one can tell me.. what to do ??any clues on this ?

3G has more power drain than wifi so it's normal.

My 3G has always had higher power drain than WiFi. There isn't really anything you can do about it other than to turn it off. Alternatively you can disable "Always on Data" under Wireless & Networks => Mobile Networks

Disable automatic sync. My data networks are switched off since last week. Now my battery lasts 2-3 days. I only use wifi at home.
You can also use juicedefender to control battery use and sync intervals.

This can also be caused by low/patchy 3G coverage in areas you are in.
If the 3G signal is weak then the handset will use a lot of power to try and keep the signal, as it prefers it over 2G.
If you don't mind the slower data speeds, switch to 2G/GSM Only as this does not use as much power (due to 3G cell breathing - Google it )

One way to alleviate *some* of that is to set the phone to "GSM Auto (PRL)".
Go to dialer and dial "*#*#INFO#*#*". That should take you to the settings screen.

Definitely true. Your cell will consume much more power when you are outside of coverage area. The antena will keep searching the network according to your preference. So if you have 3G active all the time the phones internal antenna will keep looking for it and will drain your battery quicker.

okey..
thx all 4 d answers...
goo that to know there's nothing wrong with my signal or battery..
i think my problem is bad signal coverage.. as i always be in the shop which is so inside ....
but cant make it to edge/gsm as 2g speed is awful here in indonesia...
i think i'll just use juicedefender
thx..

[Q] Huge difference in battery life between Rogers and Telus

So i was using my HSPA galaxy nexus on Rogers network in Canada for about 7 weeks, and getting quite excellent battery life (~36hours of how i use it).
I have now switched to Telus, and for the same locations and use, i'm lucky to get 20hours out of it after 2 weeks. Same phone, same software, same amount of time on wifi, etc.
looking @ the battery stats, i guess the mobile standby is higher, but not stupidly high.
Has anyone else noticed this? I know there are differences based on idle timers in the radio network etc, but i'd really like to be able to do something about this. And unfortunately moving back to Rogers is not an option I have.

Rogers has 2g network, Telus does not. When you're using wifi, you don't need rogers' data so you're on their 2g network + wifi. With telus, you have no network to fall back on = 3g + wifi. Hence, more battery drain.

[Q] Battery Usage, Cell Standby, & Network Mode ?

Samsung Galaxy S4 mini SGH-I257M , 4.2.2
I would like to understand whatever relationships exist among Battery Usage, Cell Standby, & Network Mode.
I am seeing that Cell Standby accounts for 40% of my battery usage - with GPS, Wi-Fi, and Mobile Data all turned off. I would like to be able to reduce this %.
Under Network Mode i have 4 choices ...
GSM/HPSA/LTE auto connect
GSM/HPSA auto connect
GSM only
HPSA only
Will my choice among these affect my battery usage?
What is the difference if i do not choose an auto connect option? I am guessing that auto connect simply means that the phone will choose the best option, so auto connect is not necessary when there is just one choice.
I do not need the extra hi speed of LTE. Rogers coverage in Canada is slightly better with GSM/EDGE than with HPSA. So i am considering setting my phone to GSM only.
Will i save battery usage with this choice? What do ya think?

GSM only will amount to about 50% battery saving.
Auto connect will chew through the battery life as phone radio has to search for 3G and 2G continuously.
LTE will make you run for your charger by 3 PM everyday.

Thanks. I set my phone onto HPSA Only. I'll see how this works out over the next while.

my battry is low

Need Help_battery drain on cell standby on C6502

I have C6502 on stock 5.02 with 10.6.A.0.454.
The thing is that cell stand by is far high of 37 percent of battery usage as attached.
C6502 won't last a full day, in fact it runs half a day only.
The battery draining started since soon after I changed telecom carrier to new one since this Sunday.
New SIM supports 3G data communication as well as LTE, even though C6502 doesn't support LTE.
I can call, send & receive sms, and access to internet via 3G.
The only problem is battery draining of cell stand by.
Does anyone have any advice or solution on it?

Question Australian Pixel 6 Pro users battery issues?

Hi anyone in OZ.
I have a Pixel 6 Pro on Telstra, and getting extreme network standby drain, by far the biggest % of total drain we are talking 1/4 to 1/2 the battery usage. Also noticing rubbish network signals and stability. To be fair on the phone my Pixel 4XL had signal issues on the train from Brisbane CBD to South side suburbs.
Anyone else on Telstra experiencing the same?
Anyone with other networks experencing the same, especially with 5G?
Trying to determine if my phone is a dud.
Interestingly my old Pixel 4XL doing the same as it was previously only on WIFI no mobile now lasts at least 2-3 days on the battery charge. Prior to sim being removed was lucky to last a full day.

No issues here matey. All good. I am with Vodafone 5G

Happy with my battery on optus

Out of interest. If you go into the battery settings then usage choose show System usage right down the bottom was does Mobile network standby say?

Same problem here on Telstra. Battery doesn't last a day.
Mobile standby is 20-25% whenever I look. Even if I'm on WiFi all day.

6 Pro on Telstra. Definitely noticed my 5G connection is nowhere near as good as it was on my previous phone, an Oppo Find X2 Pro.
Unfortunately I also feel bluetooth and wifi are not as good either

I am with Boost and I do see the mobile standby goes up if the phone is on idle. Like overnight, I can see in the two hour intervals that it's at 50%, but my standby drain is around 5% over 8 to 9 hours which is in line with my other phones in the past. This is with wifi on all night.
I would say the usage for the mobile standby is high because it's always connected to a network and that costs energy. I haven't done this but if you put it on airplane mode, the mobile standby should go to zero and probably the device idle or wifi will go up.

I'm with Belong, and I'm also getting a battery drain. 10-11 percent overnight. Mobile network standby is too high.

Not getting signal issues with Telstra, but have had the network standby drain issue... The latest (today) carrier services update on play store 'feels' to have improved it significantly... Though too early to tell if fixed

Those on Telstra is this the 'operator settings version' number you are all on?...
telstra_au-30000000550.47
2021-09-02

For me, yes, same operator version

I have terrible drain simialr to everyone else. Standby drain is horrendous on wifi. Around 50% deep sleep percentage when using the phone regularly. overnight deep sleep is good and drains about 1% an hr. On boost mobile. Today's update fixed jack all

No I am on .48 release date 2021-09-30.
I read a post about a new carrier services release today , which I updated to today straight after it updated the signal jumped up. Battery drain seems to be slightly better, but still garbage. Was hoping the december update would fix some issues, but definately didn't.Think I might take this phone back to Telstra for replacement

I turned off adaptive connectivity in network and internet settings, and mobile data always active in developers options. No drain.

I'm also on Telstra, battery drain at the moment is at 32% for `Mobile Network Standy`, I was in the CBD yesterday and 5G is allowed. In general my current area is not 5G enabled
My Operator Settings version is:

Yeah I had both of these settings enabled as well after reading some others feedback some time back, still extreme battery drain, now about 40%, so the carrier update helps signal strength but seems to make the drain worse.
