[G4 Q&A, Help & Troubleshooting] Almighty1:
As far as Greenify is concerned, I have only greenified things that are not system apps. As for Powernap, Google Play Store is not on the whitelist but what I'm saying is after Greenifying the non-system apps, Play Store works correctly as basically it works like the phone is new before installing a x amount of apps or when running Play Store in Safe Mode, it basically let's take for example a app with 32MB in size, you would see it go up to like 16MB and then half a second later, it goes into installing and it installs completely, you don't see the part where it downloads the 16MB to 32MB part.

Don't have a setting that turns WiFi off when the screen times out but the VPN works on the mobile connection unless the WiFi was turned on and ofcourse the WiFi has been turned off for the past week so WiFi isn't even used. Haven't used Google Chromecast in over a month so haven't had to switch to WiFi either. I forgot to mention that my Bluetooth is on all the time and Kwikset Kevo app is whitelisted in both greenify and powernap as it's needed to unlock my door when I touch it with my finger, it needs to communicate with the phone. Hassle to go take the phone out to turn the bluetooth on especially when hands are full.

As for a good signal, I actually meant walking 130 meters or so in either direction outside and the signal will go to -60dBm for 4G either with band 13 or band 4.

500ma seems to work fine from a external battery pack though, just not from the computer or a power line conditioner with a 500ma output.

As for the figures, it's from Settings -> About phone -> Status since I didn't have LTE Discovery until two days ago which was good at forcing it to reconnect to the strongest signal but now it's not even asking SuperSU for root access so I can't get that part working anymore.

What I meant was some people said the Samsung Galaxy S5 had poorer RF performance compared to the S4 and S3. You're right the figures has to be the same or else it's not a valid comparison just like looking at bars which is the reason I compare the bars of the phone to itself rather than some other phone.

You're right about the bands, for some reason I kept thinking LTE used higher frequency bands while XLTE used lower frequencies as my Motorola Droid RAZR HD Maxx did not have XLTE. I thought it was only TMobile that used 1700Mhz while everyone else used 2100Mhz.

For me, band 4 actually has the stronger reading as it goes from 90dBm to 108dBm while band 13 goes from 110dBm all the way to 113dBm. The 118dBm only happens like once in a blue moon. At home, I'm getting both band 13 and band 4 as one is on tower 349 and the other is on tower 347. For all I know, maybe there is a technical issue with the tower or there may be towers that are down as my Motorola Droid RAZR HD Maxx never had problems with 4G LTE on Verizon Wireless. The locking on a signal is what I was referring to since it seems like the phone doesn't want to lock onto signals for some reason. I mean I have noticed that in areas with 50dBm normally on 4G LTE, sometimes it will lock onto the 3G signal instead and won't go to 4G even after an hour while other times it locks into it fine.

Never really researched 3G/4G that much but I remember people were saying how the Samsung GS4 was better than both the GS5 and GS3 when it came to signal. It's also ofcourse how well it can lock onto the signal. I remember a few years ago, they said all carriers selling in San Francisco or was it the entire state of California that required it to show the RF performance of the phone at the store but haven't seen any of that. The other thing is since we're talking about the G4, I haven't updated the software past 10b to reduce the risk of not being able to unlock the bootloader so the radio firmware may be better on 11a/12a for all I know. Too bad it doesn't seem like there is a way to just flash the radios on the G4's, at least no one has mentioned how to yet or else it might work with just flashing the radios from 11a as there is no KDZ for 12A yet.

As far as increasing signal, I remember years ago, there were these sticker antennas that really didn't do anything and some people claimed using aluminum foil would increase the signal but haven't really tried it on the G4. These days, there is a company out there named Reach Antenna http://www.reachantenna.com/ which seems to have good reviews for people that purchased the product from Best Buy so not sure if it really works or not as there isn't a model out for G4's, they seem to only be interested in Samsung and iPhones.

Both Verizon and Sprint are no longer CDMA except in the 3G as I think all the 3G technologies were all CDMA based while all the 4G technologies are GSM based. I remember on older phones before there were smartphones, the GSM phones, you can basically display all the networks and then select which one you want which doesn't seem to be the case with the current phones and there isn't anything to set the scanning speed either unless Fast Dormancy is the same thing except it doesn't seem like there is a code to get to those menus on the Verizon G4 yet, atleast no one found any yet.

Don't have a spare OEM battery as I sent in the rebate for the free spare battery, battery holder/charger and leather back from LG and it appears that as of October 20, 2015, they told me that they are out of stock and the supplies finally came in and it can take another 4-6 weeks before I'll get it. The other option is calling Verizon Wireless level 2 tech support and get them to send out a battery except I can't think of a good reason to make the battery sound defective for that to happen.

As for the SD Card, the 200GB MicroSD Card which is the latest and greatest after all, even though you wonder why it isn't 256GB in capacity when supposedly the 56GB is disabled and used for something else. So I'm sure the card died because of either heat or it's a new high-end capacity product and there could just be reliability problems. This is actually the first MicroSD card I have had that had problems as I've had everything from 1GB, 2GB, 4GB, 8GB when it was still known as TransFlash to the 16GB, 32GB, 64GB and 128GB which are all SanDisk with a few PNY 16GB's and none have had problems. I still have the card as I managed to get SanDisk to send me a advanced replacement, the card basically will read and be able to delete but not write/format as it thinks it is write protected and never can past the surface test after the problem. The card has never been unmounted and is always in the phone, only thing it's used for is Titanium Backup for backup up apps. The 700+ apps are actually all on the phone itself. Haven't had to install apps on a external SD card ever since my Motorola Droid 1 which didn't have internal SD so had to use Link2SD for that. A lot of the apps and the data on the G4 unless it's newly installed apps came from what was on the MicroSD card of the Motorola Droid RAZR HD Maxx which came from the Motorola Droid 1 as I basically clone the cards each time I get a new phone. I have a G3 here too and haven't used it on the mobile side yet as with Verizon, it's a PITA to pull out the SIM on the G3 and G4 compared to Motorola's.

Just a update:

With 100% charge, I took the phone off the charger at 7:45PM and used the Bank of America app to make a mobile check deposit which basically took 2 pictures over a 5 minute period which I had to use the WiFi. After that, WiFi was off and the phone was basically screen off and so I checked and the phone showed Android at 3% and immediately went to 0% and said battery too low to turn on at 3:54AM which meant the standby time is actually around 8 hours and 4 minutes.
