I rebooted my phone for the first time yesterday evening (Camera was force closing after setting Aviate as home launcher), after that overnight phone lost 20% charge, before this reboot - phone was loosing 3 to 5% overnight.
I have not installed any new apps, also checked GSam battery monitor and didn't see any app sucking more juice. I was checking different things and noticed network signal strength is much better than normal (95-97 dbm, usually it used to be 103dbm at the same place), checked network mode and it is set as Global instead of LTE/CDMA, I remember it was LTE/CDMA before reboot and my signal was 103dbm.
During the last couple of hours also I am loosing 3 times more battery than normal, so looks like Global network mode is giving better signal compared to LTE/CDMA mode but using more battery. I am all for better signal strength but not at the expense of battery life.
Does any of you noticed similar issue? Does network mode selection has any impact on signal strength & battery life?
Mine is sort of opposite. It had defaulted to global and was at 91% battery being mostly idle for 16 hours. Just switched to CDMA/LTE/EVDO and signal went from >-100 to -97 dBm but could be normal fluctuation range. Will see how it affects battery life but so far it's still at 91% battery having switched over more than an hour ago.
I just checked mine , it showed -81 dBm for LTE. Switched to Global and it went to -75 dBm then right back to -81 dBm.
OK so I'm not sure about dpm, as far as if it's better to have a higher or lower number? But, I did however switch from Global to LTE/CDMA and I'm definitely getting the 4GLTE symbol way more than I was on Global! I was in 3g quiet a bit on Global. And Verizon has excellent reception in my area. I noticed yesterday that my wife was in lte on her iPhone while I was in 3g and we were sitting next to each other. It's much better now.

dBm... lower is better
I've noticed that around my house my S7 Edge shows very few bars on the signal strength indicator but as soon as a call connects it jumps to full bars/strength. I'm assuming this is a feature to save batter life right?
Meh. Don't read too much into signal bars.

Does anyone else get low cell reception on 4g and 3g? My 4g cell is around -107dbm with 35asu with 2 bars. Would only having 2 bars drain my battery? My 3g is even worse, although my previous OPO had nearly full 3g signal.
Is this a samsung hardware problem? Saerching around on Google seems like a lot of folks had problems with cell reception on their S6 too
Thanks
From the information I have found, it seems common that the S7 Edge has fewer bars than other devices due to that Qualcomm technology I don't remember the name.
However, what I'm finding worrisome is that, for example at the same spot, my girlfriend's S7 Edge has -120dBm 20 asu and my Moto Z Play has -100 dBm 40 asu. It's a very considerable difference, so I'm wondering whether her device is faulty or actually is the s7 edge that has so poor signal strength.
She also told me that at her workplace, where she has always had good signal on her Nexus 5, now sometimes she's not even able to make/receive calls.
I'm considering switching to ATT which requires a phone switch too. Anyway, looking to pick up as used S8 and have no ATT signal inside my house. Maybe 1 bar in some areas. In the past I would have terrible battery drain to the point of an hour of SOT with a Sony Z5C. Most battery went to cell signal. ATT stopped giving out femtocells saying Wifi calling is good enough. But... with a weak to nonexistent LTE signal, even if on great Wifi, am I going to be using up my battery searching for the LTE signal or is the S8 smart enough to no waste the battery on that? Anyone's impressions of having great wifi and no LTE on an S8 series, while using Wifi calling?
