I have a huge battery drain, and i think that is because i have low signal (look at the picture).
I tried to recalibrate battery for two times, and use it for 2-3 days, but it's alway the same.
I get maybe 7h with normal use. 50% of the time with 3G/EDGE, 50% with WIFI. screen time 1h, and turned off Auto sync.
Can someone help me? I need my phone whole day, not 7h. :S
EDIT: I'm using stock 4.0.4 with matr1x kernel
Bump?
Can't really help you as cell reception is based on the quality of the carrier. I normally experience -95 dBm and I believe it is a cause for such high drain too.
The only thing I could recommend is try flashing a different radio and see if you get a better signal?

BetterBatteryStats can let you know if it's not the radio. To test if it is the radio, try switching to 2G only.
Well, it was 3G-s fault. I switched to 2G and now there is no battery drain.
BUT, i still don't know why is there no 3G network in my house.
I have SGSII on my shelf, with the same carrier and it has 3G.
There is 3G at your house. It is just weak, much like me. A few too many concrete walls where i'm at.
Cell signals are done through waves which have to penetrate through walls and other solid objects, this vastly weakens the signal. Once you hit the ~-100dB mark your phone will start throwing more power into it's antenna to compensate, much further and it ditches 3G and goes to 2G assuming it has better coverage. Around the 100dB mark it tends to stay with 3G if data is on though which can start chewing through battery. It would be able to play around with the parameters but i don't see this happening anytime soon.
Compare the dB reading on your SGS2 and Nexus S. If it's much worse on the Nexus S, try flashing a different radio.
I have the same problem, i just switch back to 2g when i get back home and at night. for some reason, 2g networks tend to always have stronger reception
So I'm finding that my LTE coverage is pretty spotty at best in Seattle, in Shoreline (city just north of Seattle) it barely gets a signal and is usually on 4G, but in Lynwood I get a great LTE signal... It's kind of strange that there would be a gap in coverage.
Also, has anyone noticed severe battery drainage since the LTE network went live? My phone's battery has been dying really quickly with phone standby using almost 33%, and phone idle using another 30%.

Hey guys,
I notice that my S3 battery is drained when I'm at work, when my network signal is limited. It only drains when I'm in the part of the building that has poor signal reception, or if I'm at a certain restaurant I frequent where reception is spotty. I assume it is because the phone is fighting to hang on to the little signal it has... but I'd prefer to keep my battery until I actually can use the phone.
Is there a way to help alleviate this without having to turn the network off? Like increase the amount of time between network scans?
I have root.
Thanks

In an area with poor signal will wifi calling generally consume more battery or would it be better to keep it off when signal is down to 1-3 bars?
I love almost everything about my Moto G. Except the signal. I would say at least 30-40% of the time it will drop to 3G. Where on my Moto X 2014 in the same area its always got a good strong LTE signal. Does the Moto G use less LTE bands thans other Moto phones?
I have a XT1540 on ATT. The signal is decent enough to not notice a weak signal, i never have searching for service and rarely on 1 bar.
But, I have noticed that in Battery use under "Cell Standby" time without signal on lte was very high(i'm not aware when this is happening). I have since switched to "3G" only and never lose signal.
