It's all relative to how much power the phone uses. You can't really compare the battery size directly. That 3,000mAh battery is powering a 1080p screen while the 2,800mAh battery is powering a QHD screen.
QHD has 77% more pixels than 1080p. That's 77% more pixels for the GPU to render and 77% more pixels for the display to refresh. That's a lot more power usage.
Agree, but i've heard people complaining when comparing with the G4 that the battery got smaller. Initially was expecting similar G4 sot with the G5 but 6.0.1 seems to have improved things going by what people tell me. 30m - 1h more SOT. No 6.0.1 yet on the G4.
That really depends on your priorities on a phone. I personally don't take enough pictures to have camera quality at the top of my list.
Certainly so you can optimise in other areas that matter to you.
Getting 5 hr SOT really depends on a lot of factors. If you don't have wake lock issues (very common from "Android OS", "Google Play Services" and "Android System"), turn location off, Google Now off, lower brightness, stay on wi-fi, don't use the camera, don't use GPS, no music, no video, etc and have absolutely perfect cell reception then maybe.
Right, the typical use i would assume is calls, browsing, messaging and definitely on wifi. Moderate to heavy with lots of screen tapping. can use camera to take a few shots, not several 4k clips. Can have GPS on but navigation with it on a trip means hooking up a charger. If GPS can't find a satellite within 10 seconds it reverts to either cell net or wifi so GPS use is low. Where it can go up is if some app is constantly querying location data.
can have music & video. How long are we talking about. Best is if you can download first and play back later instead of streaming. If you can't then you're going to have to ration your use. Stream at times when you do syncs and check messages. Make max use of the radio interface and when you're done let it idle.
On data similar use means an hour less than wifi so up to 4h with middling signal strength. With good data signal sot will be similar to wifi. This surprised me, people getting similar times on data as i could on wifi, very good signal indeed. Mostly because their carriers are operating on 3 digit frequencies instead of 4 digit ones. Better penetrating power and longer range means less work for the phone radio to stay hooked onto the net.
What matters is run time. off the charger at 7am back on at 9pm with 20-30% left is acceptable. LG's standby is very good going by experience with the G4. I would not call battery here good, just ok but not bad. Better can be had on other devices.
How much SOT do you need ? under data or wifi.
I have a Nexus 5X so I follow the battery life threads very closely. Under PERFECT conditions the best I've seen posted is like 4.5 hours SOT with 36 hours off the charger and that was with the data connection totally disabled overnight with no camera, no GPS, no video, no music, no Bluetooth, low brightness , great cell reception(like low -80's dBm) and system services("Android OS", "Google Play Services" and "Android System") behaving like they should. Do any of the other activities that I mentioned, go into an area with less than excellent cell reception and it drops fast. The typical battery life I get and see from others is about 3.5 hours SOT over like 14 hours off the charger. The LG G5 has a battery that is less than 4% larger than the Nexus 5X's battery but has 77% more pixels and LG's crappy custom ROM to deal with. I don't know anyone with a G5 yet but I know several with a G4 and, even with a bigger battery, they have a hard time getting 4 hours SOT over a period of 12-14 hours off the charger.
If they're on data agree. If the data signal is weak don't use it. If data is the only option then get a mifi if you don't move much.
What is making android os, google play services and android system misbehave ? that needs to be determined otherwise your battery is going for a toss. If you're into battery take a look at
this. If you've used it before has it been any good.
I find the 5x's battery performance lower than expected which is surprising given its using amoled and is 1080p and still has a 2700mah battery. Yet what you're telling me sounds similar to the S6 which has a QHD screen. And the 6P from what i gather gets even less than the 5X for the reasons you mentioned above despite having a correspondingly bigger battery at 3450 mah. LG & Samsung seem better at optimising battery in their firmware than google. Sony too.
So, to summarize, sure, the LG G5 "CAN" get 5 hours SOT but that's far from typical with real world usage while still getting a full day off the charger.

5h sot and flat within 11h. LTE & wifi. Used 30% in the last 3h.
As for a replaceable battery it's a matter of what you are willing to put up with. For a replaceable battery to be of any real advantage you'd have to have an extra battery(or several batteries) with you to swap out. Who wants to carry extra batteries in their pockets? I've done it before and it SUCKS.
Lighter than a external battery ? Surely you would prefer that otherwise its a charger somewhere in the car perhaps.
