I've read in a bunch of other threads that people are getting awesome battery life out of their Z or G2. Mine is okay-ish. I had a hero before which seemed a bit better. there are a couple of odd things I thought I'd check tho...
First, the keyboard backlight turns on and off at seemingly random intervals while open. Anyone else got this?
Also I've seen screenshots of the battery use screen showing how much power is used by each system. The screen always is at least 75% on mine, even when its been sat in a pouch most of the time with just a couple of messages or a phone call- this seems quite different to other peoples experience.
Is there any reliable way of benchmarking the battery to check? If not, does anyone fancy helping me test?
im actually suffering from the same problem,
i thaught it was because the first week i was using it lots thats why the battery wasnt lasting long, but on monday morning with a full charge ,
only with a few calls , texts and checking train times on TFL , by the time i got to sleep that night the battery was on 30%
I was shocked , checked the battery useage meter , everything was below 5% except the screen which was was on a shocking 80%
I Then formatted the phone , restored to default , removed everything ,
set the brightness to lowest useable which was just above the 'o' on 'ok' in the brightness screen let it charge to 100% for use on tuesday.
Tuesday - Morn before i left for work it was on 100% , the only thing i had setup on it was email, brightness on low - but useable .
Screen must have been on onliy for 20 mins throughout the day
Got home , battery was on 45%
battery useage - again display was taking over 70% of it when it was hardly on .
I am RMA'ing this one tommorow
I think its an issue internally with something shorting on the display, battery shoudlnt be draining that much if its not on
Out of interest was yours a UK Desire Z ?
Yep. This sounds exactly like my situation in every detail. I couldn't believe reports from other people saying their batteries were at 92% after 12 hours- even without using mine at all this wouldn't happen.
Mine is a UK desire z, from play.com. I think its over 14 days so RMA might be tricky, although I know I have lots of rights thanks to distance selling regulations. Hope I can exchange without too much fuss.
Ooh, just thought of something. When I set the brightness really low on mine (below 20% or so) the screen flickers slightly. It's most visible on a totally white page. Does yours do the same? Faulty backlight maybe?

Just tested mine, definitely no flicker.
Now my experience with the battery....
I play about half hour - an hour of games every day, plus about up to an hour wifi, using the xda app throughout the day using data, 10 - 15 txts and a few 1 - 2 min calls... Not too heavy usage.
I'm getting 30-36 hours, I'm happy....
BUT..... I have not plugged in through mains once yet. I read that charging through USB gives better performance... so far that is looking true.
I got the same kind of time out of my Hero using mains but that was with zero game time.
yes! pizza65 , i noticed the flickering too! , i thaught it was just my eye being twitchy ! Noticeable on internet browsing on low brightness! .
Mine was from handtec .. (amazon delayed too much) so changed last min,
it comes with a 2 year manufacturer waranty i think so even if you take it up with HTC direct they should be able to help if play dont.
I tried a diff radio and rom , but it made no difference.
Maybe the UK batch is still faulty , wasnt that the reason why it failed google testing and got delayed for release here?
Whats your hinge like ?
ddot what network are you on ?
same to you pizza65?
im on 02 , i dont think it is a network radio issue with switching of hspda/3g to 2g signals as it does say cell standby battery useage is around only 6% , but then again the phone could be false reporting

Not really if you want realistic real-world results with data connectivity etc. It varies too much since everything counts like signal strength.
You can always just turn off everything and burn the battery with a movie but first thing you should do is a few dozen full discharges before you do anything. I've noticed that HTC (and other manufacturers too) pre-use their batteries ie. charge and recharge them until they're optimal for consumers, hence the whine about bad batteries when people buy new phones (and in reviews as well).
I'm on Orange, I don't think its network because, as you confirmed, the "battery use" screen says that the screen is draining all the power. If nobody else gets a flicker on low brightness (it can take a few seconds to see it, but once you notice it...) then it looks like our screens are the culprit. Maybe.
I've deleted batterystats.bin and fully charged, so ill give that another chance before talking to play.
Ddot, what percentage of the drain is from the screen on your z? Also, if you press 'display' in that menu it will say how long the screen has been on, what does it say?
I have the same issue with battery performace. I've moved to Desire Z from my old Desire which had AMOLED display. On my old one, the display taked 5-8% of battery. On Desire Z I have minimum 50%, but ussually ~70%.
After reading that some people can use their DZs like "for two days of heavy use (gaming, browsing)" or "5% for 6 hours" I can't understand how?
Comparing to old Desire my DZ have poor battery performance. But the specs tells it must be much better.
I'll publish my battery usage stats after some days. Maybe it'll be useful.

Very interesting, thanks for sharing
And a really "geek" method here quoted from cyanogenmod issue:
Comment 27 by david.j.erickson, Aug 19, 2010
Now, I was still having abnormal drain on my battery. As suggested in the Wiki and also confirmed in another cyanogenmod post, clearing the battery stats can help. I followed this procedure:
Fully charge the battery, says Full and 100% under Settings - About phone - Status.
Reboot into recovery, wiped battery stats. Phone still plugged in at this point.
Reboot into rom, checked to make sure battery was still Full and 100%.
Unplugged phone.
Killed it, used Maps on Wifi and messing around. Killed it in about 3 hours or so.
Tried turning it on a couple times to make sure it was *dead* dead. It still tried to boot, but couldn't complete without shutting off.
Plugged phone in, booted it up. It may be better to not turn it on until it is fully charged, but this is just what I did.
Let it charge overnight, next morning took it off charger since it was full.
I have noticed pretty good battery life since doing this. This morning on my bus ride in I pretty much constantly played some Storm8 games and used Listen with Bluetooth, was only down to about 82 or 84%, can't remember. This is on par with previous CM release for me.
Not sure why this rom in particular had so much worse battery drain out of the gate, and not just for me. Fortunately it seems correctable. Maybe if a few of you could give this a try and see if it improves your battery performance we could conclusively say battery calibration is the solution.

What about the flicker? Can anyone confirm that?
I have a UK (read: QWERTY) Desire Z, first batch.
I tried reprodocuing the flicker by lowering the brightness completely and looking at a blank white page in the internet browser. Couldn't see it. Maybe I wasn't looking hard enough.
That said, I'm not getting the great battery life that most seem to be getting, and the stats always show the Display as being the number one drain. HOWEVER, it doesn't seem quite as bad as you guys are saying.
Right now, it looks like this:
Unplugged for 18 hours and 16 minutes, battery at 36%
Display accounts for 41% of the drain
It has been on for 50 minutes.
(stock ROM, running an IM client 24/7, synced to three email addresses... Typoclock seems to use 2% of the battery every time as well, which seems relatively high for such an innocuous little widget)
Yeah. I have some slight flickering too, slight when low light set.
Uk stock.
I dont think high display percent is an issue too much reading cyanogen issue comments.if you use nothing but low cpu burden apps, display should eat most.
Also if i have it off, power is eaten by cell standby.
Im still hoping for a settled battery log mentioned in forums.
My 2 cents:
If I "use" the phone, I have to plugin it every night.
If I do not "use" it (nobody calls that day, no browsing or GPS (Just work!)), I plugin it every two day (ex. mon - wed - fri).
The display is always 65-80 % of the "drain problem".
Today the stats are:
7.30 am: full chargerd 100%
7.30 pm: display drains: 70% in 1h : 21m - battery at 20%
I leave automatic background gmail sync on (only daylight, I use the "Flight mode" overnight)
No bluetooth, no wifi, no gps, brightness 35-40%

No phone either.
I'm on a North American Desire Z and I see the display using 70%-80% of the battery when I have the display on for approximately two hours out of the day. I keep my display quite dim too, at 20% brightness.
I'm also running everything stock. No root, no custom ROMs, no anything.
Isnt display percentage actually the display driver cpu time eaten?its just a theoretical value isnt it, not watts gone? It seems obvious that its eating a lot as it refreshes all the time regardless of display light level.
My screen on is only 33% today, im sure its usually higher though. Maybe its due to me flashing stuff all day. Ill do a full charge tonight and report back Sunday.

As I posted in another thread:
I am lucky to even get 12 hours with minimal use. No calls, just some texting and maybe browsing my bank website. Screen is always the killer for me, even on 20% brightness. If I go lower the screen actually flickers.
I bought the red HTC Chichitech batteries and they didn't help me at all.
Tried overclocking module, didn't change much.
The only app that ever shows any significant battery use (over 5%) is Maps, when I use maps.

I am rooted, S-OFF, using the Sense Modaco ROM. Battery usage was no better with the Stock Bell Rom before rooting or S-OFF.
My main concern is the screen flickering at low brightness. it's as if it's unable to decide on a specific level of brightness and makes me question if it's actually saving any power.
I set my phone to Auto brightness and I am going to see if that is actually worse of if it's on par with 20%.
Ugh - just realized there is another thread pretty much all about this. I thought it was a different issue. Still, does anyone know if there is a better batch of phones or something? I have a FutureShop warranty so it'd be easy enough for me to replace if it will actually provide a solution
No-one has posted anything, to my knowledge, about a different batch of phones having better battery life. I would check out the other threads about battery life (including those on the G2 side too) and see if you can get yours to last better. But it could just be something faulty on your phone/battery.
Auto-brightness would make it even worse..because there is some type of bug or something that isn't making it function like it should. I was also getting terrible battery life until I followed some of these steps: http://www.goodandevo.net/2010/05/20-tips-to-improve-htc-evo-4g-battery-life.html
Biggest killers are any widgets that are constantly updating..or facebook/twitter apps that are constantly updating. As well..i recommend SetCPU to underclock your phone when your screen is turned off. This should also help with conserving battery life along with some of the steps provided in that link.

I am considering waiting a month or so and then having mine replaced. Unless I managed to figure something else out. My HTC Legend had better battery life.

The reason I want to try auto or higher brightness is to see if lowering it was actually saving me any battery life. I am curious if there's a driver or display issues that causes it to use the same amount regardless of the setting. So far I don't seem to be running out any faster @ auto than I was at 20%, but it hasn't been a long enough time to tell for sure.
Also I am unable to do the battery tip for the evo because once I turn off the phone and go to charge it again, it's instantly green. But I am going to try it anyway even though it's green.
Since writing the first post I used the OC module to get my phone to 1.2ghz. I have SetCPU set to run on boot with the onDemand setting. I have a profile that says to slow the CPU when the screen is off. From what I've read it doesn't make a ton of difference with this particular phone, but we'll see...

Yep, that's what I found too, when you try and charge it thinks it's already charged and goes green straight away again. But as you said, worth a try.
I just wanted to report back and say that I had my phone replaced. So far so good:
- No screen flicker issue at low brightness
- Battery has lasted nearly 20 hours with moderate-heavy use (played NFS Shift, setup basically everything on the phone after rooting, installed all my apps, backups, flashed some roms, 20+ texts, 3-4 short calls, showing people random apps.)
If it's not all in my head then this is definitely much better now!
Curious. It seems that everyone who reports the screen flickering problem has poor battery life.
Defective displays?
I feel my battery life is pretty bad as well. I've unplugged the phone this morning at 7 AM. Now it's 2 PM, and I'm at 37%. In between, the only things I've done are: send/receive a few emails and chat on gtalk. Brightness is at 40%, animations are turned off, wifi and gps location off. Using latest Cyanogenmod (6.1.1) and have no screen flicker issues
Edit: 17 minutes later, it's now at 27%
How long have you had the phone for?
Initially the first few days I got the phone, battery life was really bad, could drain in a few hours.
After a week or two of use, I now have reasonable battery life, the phone can last all day with light usage and still have lots of juice left. Actually I think if you make a few calls and a few txts, battery could last 2 days. If you play with it, one day for sure but you need to plug in over night.
(if you're talking to me) It's quite new, just picked it up on Friday actually. Also I've kept on researching, and it seems that poor coverage (like I have at work, from 7 til 3) tends to drain the battery even more, since the phone keeps switching between HSPA, 3G, etc.
I had my first one for about a month at least. This replacement was from Saturday.
Today I've had my phone unplugged since 8am, it's 5:30pm and I have 45% battery left, but the screen is the #2 user. Standby is #1 @ 40% of my battery usage, due to over 4 hours of time without a signal. The screen is only 24% and has been on for 48 minutes. Voice calls is #3 at 23% battery usage, with 23mins of calling.
My other phone would have died by now.
Also I spent an hour of streaming bluetooth audio to my car. Bluetooth doesn't even register on the battery usage. I've never seen it use more than 2% and it's always on. I am not sure why people say it uses a lot.
Just want to share my experience.
I too had poor battery life. Stock Bell ROM. Got to 3:00 pm and it used to die. Use this for work. Pushing data all day from Exchange server, bluetooth on all day because I'm in and out of the car, talk on average 30 minutes per day, texting, surfing, tethering, blah blah. Believe it or not, my old Omnia II would get me thru the day no problem.
I was also tempted to return it. But I decided to try a few things. Installed Set CPU and a task killer at the same time. Shut down as many tasks as possible on start up. Widgets and accounts, except Exchange-push, run and sync every hour. I get about 40% battery by dinner. I am happy now .
I'm quite happy with my Desire Z's battery life, It lasts for about 36 hours with moderate use. I have Juicedefender and Ultimatejuice installed, data or wifi are opened only when an app needs data connection, this increased my battery life by 10 hours or sth like that. Nice app.
I had terrible battery life until I went overseas. It is a stock Bell ROM, but I arrived in Spain Monday and am using a Spanish SIM card.
My battery life has increased from 14 hours with Bell's 3G signal to my current 27 hours and 35% remaining battery using GSM and WiFi always on. Funny thing is that no matter where I am it says the screen is by far my biggest power drain.
Where did you buy your Desire Z and how did you get it replaced? I'm with Bell and they would take mine to send out for "repair" but not sure if that will do anything. This will take 3-6 weeks apparently and I'm not sure if they it is worth it.
I'm running 10 hours with that I consider fair usage (few calls, text, map/gsp, and facebook.) My display is the highest battery usage at 60% and on for about 1:45h. I'm very disappointed.
Hey,
it's the same with my G2.
Max 24h.
I've standard ROM installed.
No WiFi.
Brightness to about 30%.
Juice Defender is installed and I'm surfing and just the regular stuff, but even if it's just in standby, it's taking a lot of power (display takes most)
Best!

I bought mine at FutureShop since I didn't think Bell would let me without buying at least a month of service (or being an existing customer). I also purchased FutureShop's extended warranty which is how I was able to get it swapped for a new one so quickly.
I use the extended battery for the evo. Lasts about 1.5 days with ass loads of use. Just have to trim the plastic edges a bit.

I have a couple of those red chichitech batteries but I wasn't able to notice any improvement with the problem phone.
My Desire Z also has a flickering screen at lowest brightness, and with moderate use it dies after about 12 hours max. Even on lowest brightness the screen ueses 59% battery. I rarely manage to make it through the day without having to charge the phone. Im on stock ROM with latest OTA (1.72) btw.
Gonna have it replaced next week just cause of the flickering screen. Has anyone tried the 1700mAH battery from seidio?

Sorry for my bad english
What drain?
Are there really so many problems with drainage on CM7/GB builds?
2d, 3h, 25m on battery with 60% left.
The first CM7 build i used is the one in my sig. I'm amazed by the lack of problems with this build
The only drain that's still ongoing is bluetooth on standby drain AFAIK. This DSP issue is not related to the HD2, thus I don't think it's valid to implement. With bluetooth turned off and heavy usage, I get roughly 2 days out of my device also... I really don't think the drain is a big issue. Honestly, the biggest issues is (And it's not much): Robot voice once in a while, some Wifi issues (EAP mostly), Wakeup lag and BT drain on standby.
the drain is related to the toolchain used to compile our kernals and roms?). I however can do easily 3 days with out charging on android, using the same setup as KrewsialNL
Actually
Actually, i get pretty horrible battery life across all builds...
it could be that I have a v1 TMOUS hd2 though... something is weird with it. I always get random energy spikes (even with sync off)
can't get more than 14-18 hours...
My battery drainage is fine using the Typhoon rom. I think some people are expecting a little too much out of their batteries.
It's only 1230mah if it was 1500mah it would have been way better.

How on EARTH are you getting that long out of your battery?
Are you using the phone at all?
I've used loads of different builds and never come even close to half that battery life, in fact no more than about 20hours MAX with light usage.
I am using Juice Defender to disable my WiFi and Data when the phone is not in use too.
Any tips?
I have run all the latest GB builds and I also get this weird spike (around 70mA to 100mA) usually when I leave the phone overnight (not charging) and this drains my battery down to almost empty by morning. This is with bluetooth off and wifi on. No apps installed on the phone.

Well I was going to say exactly EXACTLY the same thing! Except that i didn't like Juice Defender
Is battery THAT GOOD?!?
Battery
well yes, it's certainly feasible...
it's just that MY hd2 specifically gets random spikes in energy usage.... I'm not sure why, been trying to resolve it for a while.
I don't really get those spikes in WM, only when I go someplace that doesn't have signal... it will spike up initially and then settle down (dutty's rom)
However, with these android roms.... i get random spikes of increased current around 100-200ma while the phone is in sleep. Bluetooth off, sync off, wifi off etc.
also, when the phone is in use... it is not uncommon to have current of 400+ consumption... hitting 500+ when web browsing...
I never got this high in windows mobile...generally around 400 when streaming youtube in wm. I'm wondering if it is an android thing...
edit:
in a perfect world, our battery consumption should stay around 4ma constantly... Which we know that isn't always the case because we have data syncing and signal strength changing...but to give you an idea....
if we have a 1230mah battery... dividing that by the current draw (4ma) gives us a standby time of ~307.5h....
that's ~12.8 days
however, with my current usage... say, i'm getting about 14 hours out of my battery... that's like if i constantly had a current draw of ~68ma...
Taking a look of my usage charts.... if we say the phone is only in use for 6 hours, and the rest is in standby for 10h at 4ma...
the 6 hours would have a power consumption of ~300ma the whole time....
which i think is kinda excessive....
meh. i don't know.
perhaps i'll upload my usage charts later... lately on this new rom, i've been getting only 8 hours of battery :/
but it could be because i've been playing around with it too much
I am on a TMO US HD2 first generation and I am doing good if I can get 6 hrs of battery with the stock battery and normal usage. No wifi, 3/4g, no GPS, and auto screen dim. If I am using the net or something like angry birds I am down to 2-3 hrs max. I have tried underclocking and still not getting a full 8 hrs of life. Would love to find a solid rom that lasts 12 hrs or more. Ordered an extended battery so maybe that will help a bit.

Thanks for the tip. I have a second HD2 that I test builds on and I was actually in the process of installing the ROM you mentioned last night I am excited that this may be the rom to drop on my daily driver I have noticed that non GB roms (2.2) seem to have much stronger WIFI signal strength so I am hopeful this GB version will have solid WIFI signal too. Love using GB but hate the wifi issues I keep having. Thanks agian for the tip.
Well, this thread didn't go anywhere.
I'm finally trying to get up the courage to switch to a NAND rom.
I get awful battery life out of my SD build I've been playing with and that is with a 1500mAh replacement battery.
I'd hate to switch only to find myself in the same position?

I can confirm that from my experience, i was not able to use the phone on the second day (total up time 1d + 12h TOP) when i was on SD builds
BUT.. while on NAND (no A2SD no Data2SD)
I can confirm that i can now use the phone for 2d + some hours, depending on use.
All battery info apps told me that battery life is Good (not excellent, not very good).
Made the switch. Battery life as good if not better than with WM and SD build. I feel the biggest improvement came when I installed setCPU.

I found a very good program for my Motorola MB525 (Defy) for monitoring the battery draining from the market.
It's name is Batery Monitor Widget and it's free.
With 81% of battery it says only 7 hours and 16 minute left without doing anthing!!! The data is on and Wi-Fi connected to my home network.
Is it normal?? In the night in airplane mode after 9 hours it drain 8%-9% of battery. Again: is it normal???
If you can try this application and report your results...I think there is some application that drain my battery!!
Thanks!
Not really a comparison here, just a little story.
Yesterday i screwed up my Defy playing around with some rom. Nothing terrible, but i had no time to re-flash another rom, i had to go to work. So, i pickep up my old SE xperia x1.
After an entire day, 4-5 calls and several sms, that phone drained less than 10%. Then, last night i put the x1 in stand-by, well, that was a real stand-by, no power consumption at all.
Now i'm back to Defy, 2 hours, 15% drained...
All this just to say android is amazing but terribly hungry of power, even when the screen is off, even when airplane mode is on. I don't need a comparison to know about it
EDIT:
you said your wifi was left on, well android is hungry of data too. Even if you do nothing while wifi is on an amount of data still flows, sometimes i can see several mb downloaded by my Defy in a few hours, but no real usage by me. This also contributes, you should try to turn the wifi off or disable background data when you don't need it.
In standby (3g, sync only calendar and contacts) I have 1-1.5% battery consumption / hour. I think this is normal
With my normal usage i have some 20-40% left at the end of the day... also Ok.
WIFI on & connected will consume a lot of battery so I am not surprised.
BTW I also had an Xperia X1 and the consumption was roughly the same as the Defy... In fact more than 1-2 days on a charge I very rarely had on any of my smartphones with normal usage.

last week I was working in the forest for a few days with no signal at all, so I turned on airplane mode: I remember it going from 45% in the morning to 42% in the late afternoon!
(with everything turned off, just used it occasionally to have an idea of what time it was)

It's ok to be an android fan, i like it too, as i said it is amazing. But, battery life is definitely NOT the strong point. I can compare the two phones now, at this moment. Honestly Defy's battery life is a lot shorter.

what's the other phone you compared?
I really don't have problem with Defy's battery life. As far as my memory serves, all cell phones I ever owned (7~8, all nokia, se, moto) could standby (just standby and don't use at all) for a week or made around 5 hours call. In my case Defy can also standby for a week or allow 5~6 hours usage.
I'm on a 2g network (probably helps alot), as I have wifi at home and at work. I have an exchange email, a gmail, 2 yahoo mails, and a weather app, all allowed to sync at default settings. I don't have facebook or twitter. GPS and bluetooth are enabled only when necessary (occasionally). I overclock Defy to 1000Mhz with SetVsel, and underclock to 300 when screen off. With conscious observation over some time, I find that 1% battery is consumed around every:
- 2 hours standby with wifi off; or
- 1 hour standby with wifi on; or
- 3~5 minutes usage (calls, emails, surfing,...)
thats some amazing battery life u got there abc ...what rom are u using?
hey guys, just a quick question. with which setting do you think i'll have longer battery life: 800MHz/58vsel or 1000MHz/56vsel? btw, i got my phone stable at 800MHz/45vsel

I was using the orange 2.2, and am using the finland 2.2 now. Both have similar battery usage.
But I have uninstalled some stock applications which I don't use but keep running in background, like BlurHome.apk (with Launcherpro), InPocketService.apk, ToggleWidgets.apk (with ExtendedControls), WeatherWidget.apk (with FancyWidget), VSuiteApp.apk etc.

You may be right, I had the Xperia X1 something like 1 year ago.
I had until now FSC T830, HTC Hermes, HTC Diamond, Xperia X1, Samsung i7500 Galaxy (my first Android), Acer Liquid and now the Defy. As far as I remember I always had to charge every night (or every 2 nights at best)
Overall I think Android battery life is worse than Windows mobile was BUT I also have more background programs running now than I had in the WM days.
What I definitely don't like in Android battery life is lack of consistency. One week you get30-40 hours at a charge and suddenly 12 hours... Than you have to make detective work: look what new App might be the guilty one, check what's running in background, reboot and see if it happens again, factory reset, etc. I guess this is the price of freedom
Im on uk 2.2 and i get three days at a push i jus have a weather widget on sync every 3 hours.
Iv also undervolted 300/16 600/29 800/39 with setvsel on performance mode and up threshold on 99% and limit to vsel 1 when screen iz off
Im on three uk so im constonly on 3g and use no wifi etc etc with normal sms usage and a few calls through out off 1 charge

There has to be something wrong in your case. I find that there seems no wifi/2g/3g connection. Could that be the problem?
I dont use 3g ..cuz its expensive in my country ..and I only turn wifi on when I need it
And that shouldnt be the case ...I think id loose a lot more battery if wi-fi would be on all the time
Hello all,
I recently purchased a LG G4 Back In July , on Verizon, switching over from A Galaxy Note 3 (Tmobile). Honestly I really really like the phone, but I think the battery life is pitiful for a $700 dollar "Flagship" phone. I mean not once has it ever lasted the full day. I had to buy a spare battery kit, with 2 batteries, and days when im out from 6am to late at night, I go through 2 batteries, and have to put the 3rd one in. I mean , this is simply unacceptable for a phone like this.
Also, the camera is excellent WHEN it works. A lot of times, it doesn't take the picture right away, there is a delay, and many times it falls out of focus. This is certainly not the high quality camera they advertised.
I am hoping there is a way to fix these 2 issues, mainly the battery issue though because it is awful in my opinion. Is there any tweaks or fixes for these issues?
You've barely given any relevant information other than how unhappy you are with the device, so I would suggest that you elaborate on that.
You could inform us if you're a heavy/light user, if you keep NFC, LTE, Bluetooth, Syncing, Wi-Fi, on during the whole day or maybe if you are used to 100% brightness display. Maybe you should check in your settings what is draining your battery and provide us the info.
I'm having a pretty good experience with the phone so far. It surely lasts a whole day with 3:30 to 4h SoT. I don't even need/have a spare battery.

One person having an issue doesn't mean it's not a great camera. You'll find it's likely still the best flagship camera of any OEM.
Battery use is so dependent on which apps you run, which mods you have, how often the screen is on, what brightness, signal strength, wifi, bluetooth, etc etc etc...
I came from a galaxy s3 and reckon the battery on g4 is awesome. I use it solidly on internet for 2 hrs a day (to and from work), check messages etc through the day, usually internet at lunch. And then evening time check facebook etc over WiFi infront of telly.
I unplug at 6am and plug in around 11pm with around 3% left. I bought a 2nd battery and only needed to use it twice. It has to be how you're using it.

13 hours on battery for me today and still 71% left. Light usage but it does illustrate that the battery life can be excellent.

of course, you can get excellent battery life on every smartphone - just put it in aeroplane mode..
I get MAX 3h of SOT time on my G4 - this is with fixed brightness at 65% (at all times) and only wifi and 3g enabled (NFC, bluetooth and everything else is turned off all the time)
to be fair I have yet to own a smartphone that lasts me more than 4h SOT..
the thing that annoys me the most is the broken knock code used to unlock the phone - it works 20% of the time at best
its a completely broken feature LG has not properly addressed since launch of the device (I am on V10e software)

There have been numerous firmware updates since. Have you ever performed a full factory reset after getting those updates ?
If the answer is no, then this is one potential reason for poor battery life. What you could try is to clear the system cache in recovery. Note, i said system cache not apps cache. Idea here is when updates come in there could be conflicts and it causes the system to work harder. clearing system cache might help, if it does not then the only option is a factory reset and then a manual install.
not restore. You install apps in batches, monitor, then install more and so on. You can restore contacts etc. but apps themselves will have to be reinstalled. Sometimes apps go rogue and have to be reinstalled. Its hard to tell which app is causing the issue. Otherwise you could just reinstall whatever app that seems to be taking up more than it should be.

What are you doing on your phone ? mention apps.
How do you access the net. How good is your signal. What are you doing when you access the net.
Also, the camera is excellent WHEN it works. A lot of times, it doesn't take the picture right away, there is a delay, and many times it falls out of focus. This is certainly not the high quality camera they advertised.

What types of shots are these. It can happen with portraits some times. It will focus on the background behind the person instead of the person and the face becomes softer and the background very sharp.
For this set focus little above the chest instead of the face. If they are wearing dark clothing this will cause other issues so focus on something else at equal distance that isn't dark.
Always check the shot at the pixel level soon after you took it. Rather than at the end of the day.

Just to clarify: I had everything turned on for those 13 hours - wifi/data/bluetooth/GPS. I also made 2 phone calls and did a bit of Chromecasting using the BT Sport app for a couple of hours. Or to put it another way, I didn't take any measures at all to preserve battery life.
I used to complain just like you're doing OP ( @dredmentia ) and fixed it all with a Zerolemon battery .
Is the phone bulky/no leather back/not easy to handle... , it sure is but if battery life is crucial then it gotta get fixed.
End my day anywhere between 7 to 13 hours of sot depending on WiFi or 4g and high CPU freqs, tried light usage and hit 3 days with 12 hours sot. Snap/insta/twit/fb/periscope/... Nothing kills this battery in a day.
When and if we get a kernel I'll move back to factory battery at least then I know I'm in control of how CPU works coz while optimizing the phone for wakelocks that's the only thing I have no control over...
As for now I'm just trying to burn thru this battery every day so I can charge it every night...
Last phone was a Z3 Sony and that really grabbed my attention with its battery life in stock form, almost too perfect, Almost.

This is what your talking about? Looks like a pretty nice battery.
LG G4 Battery Case, ZeroLemon LG G4 8500mAh TriCell Extended Battery + Soft TPU Full Edge Protection Case (Compatible with all LG G4 variants) (4897010519648)
It works with the USB charger that came with the phone ?
Did someone seriously just ask me if I kept the brightness on the screen at 100%???? Obviously im not doing that, im not some idiot. I know the screen eats up most of the battery. I keep the brightness extremely low way under 50%, or on auto., The battery still last a short amount of time. Its not acceptable

Then maybe something is wrong with the phone. I got also 4-5hr SoT.
It can't be just 2hr.
