[Q] Questions about battery - G3 Q&A, Help & Troubleshooting

I want to buy a g3 i heard that this phone is really good on every aspect, but someone told me that the battery life isn't that good and the battery easily heats up.
Is that true?
I have one more question, I know nothing about android so my question is can I use stock android 5.0 on g3 instead of what lg is giving me on the phone?
Thanks.

Battery is great on stock lollipop, I get 5 hours of screen time and 24-25 hours total.
There is no stock android on the G3, closest thing are CM roms.

Like said, battery is good. Could be better I believe but it is good. Getting also like 5 hours SOT.
At the moment there is only CM 12 that is close to AOSP Lollipop.

odd im only getting 3 hours sot :/

Really depends on what your doing with this screen on time browsing,watching video,playing games
Also what brightness settings each user is using so results will vary

I'm kind of in the same boat. One of my employees got the G3 (I currently have the G2 and love it but I'm cursed bc my brain thinks I always have to have latest awesome sauce phone. ugh) and his battery life has been horrendous. I'm talking half of what the G2 can do. I know that QHD display will chew battery and all but that seems overly ridiculous. In the span of an hour he went from 100% to 82%. I checked his device for every possible thing that could be causing it and found nothing abnormal. His android system usage is at a constant 47%. I went through apps he didn't use and disabled what I could (he's not rooted. Doesn't really know much about android but I converted him with my constant iPhone bashing =D) without Titanium Backup and from what I can tell it just seems like the stock software of the G3 really isn't optimized all that well for performance v battery life. Nowhere near what the G2 accomplished. It's disappointing bc the device looks amazing but if the phone drains that rapidly for seemingly no reason I am going to hold off until they hopefully release a software update to fix the drain. It may very well be he got unlucky and got a lemon battery or it could be LG didn't put a large enough battery in the device (only 200 mAh larger than the G2) to handle that screen. I'm kind of leery of the device now. I am waiting to see more user reviews of the device. A lot of review from tech sites keep saying the battery life is good but not great. I don't consider a device barely making it through an entire work day with limited use good.

If his android system is using that much battery there's something turned on that shouldn't be. I highly doubt an OEM would go backwards in terms of optimization. Android system could be a number of things like WiFi scanning always on or location reporting on high accuracy.
I have both. Selling my Note 3

Im aware the device shouldnt be throwing those system totals out but it is. Ive checked everything and compared his G3 settings to my G2 (running Optimus G3) and changed literally everything to my setup. Didnt make a difference. Its weird man. Ive never seen system usage like that and then havent be able to find the culprit.
I had a note 3 and the G3 was a big upgrade. Is much better and for me the battery life is better. The UI is much better looking and there is less lg bloat in the system then tw has. My wife's s5 has a baby monitor progress running stock. Who needs this? It's just dumb little things like that that bother me about tw.

I wouldn't mind the heating or lag, the random shutdown on the other hand is really something to be aware of. Happened twice to me this day...:-\
Battery life is great to me. 15-20hrs of standby with 5.5hrs of screen on time.

I've had the G3 since it was released, get almost 2 days or more battery after disabling a bunch of apps, till they get root for the Sprint variant.

Just FWIW, you can't judge battery life on an occasional dip in the percentage. The battery meter isn't perfect. You'll find tons of people finding that the percentage sits at 100% for an hour and then drops quickly after that. The battery didn't simply not drain for an hour and then start draining quickly, it's the software trying to approximate. Go from full charge to near dead and see what happens.
I get great battery life. Only issue I have is the camera. Pics just don't seem that great.

So how do you like it so far?

I'm going to be getting the G3 Friday and enroll in the new $100 for 4 people with 10gb data plan. Wondering how do you like your guy's G3's so far? Is the battery life good? 3gb of sufficient? Does the snapdragon 801cut it for you guys?
One thing I noticed was the development for this phone is slower than other G3 phones even with an unlocked bootloader.
How do you guys like the screen? I liked it but sometimes I thought it might look washed out just slightly. And the digitizer effect is there alright. But over all its the best phone to get right now.
Also for the techies, how much vram does the adreno use out of the 3gb memory. I bet its around 512mb huh?
Battery life for me kinda blows. Screen on kills it pretty fast. Out does look amazing though. I switched from a Sony Xperia ZL. I like the G3 better but there are things I like about the ZL over the G3 and vice versa.
Get it. In my eperience the battery life is amazing. I get 30+ hours with approximately 4-4.5 hours screen on time. As you mentioned It's also arguably the best phone out atm. The screen is beautiful and nothing I've seen comes close to it (s5/m8). The only issue I've had so far is the phone getting too hot but that's probably due to the fact that I've disabled the auto brightness feature when the phone gets too hot. I may have to change that back if it occurs again. All in all I couldn't be happier with my purchase!

I got my G3 this morning along with a S4 for my wife when we switched from Verizon to TMO.
I had a S4 with Verizon and absolutely loved it. Had it running to perfection with safesterap and Echo rom v26.1............could get 36hrs between charges and I had it set up sweet
SO it took a bit to get everything set with TMO, and get all my basic apps set and my Apex launcher set before I rooted and set all the rooted apps up as well as loading the latest TWRP recovery.
I gotta say for what I have seen so far, its so fricken worth it. G3 tweakbox gives about 90% of all the customization I need....be good to throw a theme on top of some of the stock stuff but heck I can live with that.
I'll update in a couple days, but so far, I am impressed
I've had the g3 for about 4 days. Coming from Nexus 5. I don't like the default launcher so installed nova prime. Nova prime forgets its the default launcher about once a day. LG Health is nice but you have to set up a shortcut action on nova. It doesn't show up in the apps list. I installed the google keyboard but get the gapps crashed message on each reboot. I think it's because the g3 ships with 4.4.2. The screen on the g3 is really nice. The battery life may be nice. Never really left it as my regular phone line longer than a day.
I like it. I just like the nexus 5 with purity ROM more. I switch back and forth every so often. About 90% of each day I'm on the nexus 5. Is it worth the cost for 10% use? Probably not. I have about 9 days to decide whether it's worth the cost.

I got my G3 on launch day. I used the stock launcher for a day, then installed Nova. Nova has never forgotten it was the default launcher. I still use the stock keyboard. I have never received a gapps error message. The screen is awesome, but I think 1080p would have been fine, with longer battery life to boot. The G3 battery lasts a whole day, but my Note 2 went even longer. However, I am very pleased with the G3 and plan to keep it. It will only get better as development expands.
I still have no idea how people get amazing battery life. I picked up the Verizon one and have great signal almost everywhere and best times I have gotten were 20 hours and 3 hours sot. How people are getting, 30 hours and 5 hours sot is beyond me.
It's a great phone, gets me through the day, who has is honestly all I need, however it's not much different than anything else out there.
I personally enjoy my Flex just as much. Just too big for work now and having to switch carries, however rest of the family is on T-Mobile.

I think most people were expecting adequate/sub-par battery life due to the amount of pixels being pushed through the same 801 processor when compared to S5 and M8. To me, the fact that it holds up to the competition (1080p) and even sometimes outperform them, is a win for LG and G3 consumers.

Help me decide

Hi guys. Help me decide. I don't know which phone to get. Right now my S5 is at an auction on ebay and I was thinking of replacing it with the G3 but the problem for me is battery life. How bad is the on screen time? I would settle with an M8 but i just can't handle the camera.

exactly the same for me..i have the G3 and the S5 i know it's not the same screen but i'm waitin' for the new 10g update to see the battery life and if it's nt concluant i will sell it.
The S5 definitely got better battery life (screen on time)
It would be a bit worse/on par with the M8 i had 2 months ago!
The battery is not bad but also not that good.. maybe with some tweaks like greenify, rooting, freezing apps.
I get about 3 hours SOT and 1/1,5 days
Edit: I have the 10G software
There is like 2 threads about battery life already.
Search.
I had a s5 and I never got the screen on time as I do now with the g3! All depends on your usage
Sent from my LG-D850 using XDA Premium 4 mobile app
exactly..it depends your usage.
I get around 6 hours of SOT, thats enough for me. With ART and nova launcher there is also no lagg at all. I considered tobuy the m8 too but since it was the size of the G3 witha smaller screen i chose the G3. I just couldn' get over how much space HTC wasted with the stupid logo in the front. If it's really necessary like they say, they could have at least kept the buttons like on the m7. This way you have the wasted space and onscreen buttons which take away even more screen.

[Q] How is battery life compared to G3? (g3 owner willing to buy g4)

So, title self explain. I have G3 and want to ask to someone who made the upgrade from G3 to G4. Is the battery about the same as G3 or is better?
i had G3 and recently i bought G4 not much difference but lets say the G4 win with alittle bit but from my opinion i didnt see abig difference
advice :Stay away from G4--- this device has too many hardware issues

Don't feed the troll :good:
i was planning to buy the G4, so i looked at some reviews. GSMArena said that the battery life on the G4 is a downgrade from the G3.
The Endurance rating worked out to 54 hours, 9 hours less than the G3. The issue was with the high standby power draw, which puts a strain on the battery even when you're not using the phone. The other disappointment was the talk time, which couldn't reach 17 hours - an 8 hour drop from the G3.
We reran the tests several times and kept getting the same results.
Anyway, the web browsing time was pretty good - nothing spectacular, but good. It also marks the only improvement since the G3 as the video playback is below average for the flagship class.

ok. where does it make a direct comparison to the G3. the video is kind of hard to follow. Unless he has both phones in the same video and do a same battery test, you can't really compare the g4 to g3 with this video. the OP just has to decide which source he deems more reliable.

yes because this is a difficult subject so keep a note when he talks of the sot's under different conditions.
Had to watch it a couple of times but i got it in the end. See the comments too.
What is your expectation of sot/runtime ? How much do you get with your curent device ? what is your current device.
There is no difference between G3 and G4 for battery life max i can get 4 and half hours for battery life and minimum only almost 3 hours SOT. Maybe if next LG device is like this battery life i need to change to another brand
Yeah my experience in two days....Touchscreen issues untill i updated to V10C which fixes the touchscreen issue but decreases battery life to the extent where u can literally notice it drop before your eyes. The power saving used to work fine before v10c now even tho i turn it on immediately it wont kick in untill battery reaches 15% ( u will know when its on because the statusbar will change its color to red)...... And yes the back buttons are loose and feel wobbly. There is a pink shade in my front camera when there is sunlight in the background....ummm what else......i am damn sure even the cheap chinese phones coming out will be better than this piece of junk. I shud never have bought it

Really ? how many people are affected ? just one i saw in this thread. So the update did not cause battery problems. v10c is for euro h815.
How much sot & runtime did you get before the update ?

many times its because people are interested in some other phone that came out after.
Dont expect anything crash hot from the battery performance. It is nothing like what i expected. If you want good battery life go with samsung s6 or even better the sony xperia phones. Xperia has best battery life. So G4 wont do you any good with battery life

3h sot, lots of complaining, 4h+Sot less complaining or it goes silent. Seen this a few times now. That is what surprised me. Until you realise that people find 8h run time too short but once it gets into 12-14h+ its ok. Its the standby time that is more important.

I currently have the nexus 4 and i think the most screen on-time i can get before my phone dies is 3 hours, but usually it's in the low to mid 2 hour range before i have to run to the charger. But the phone never last more than like 12 hour of usage (or a 8 hour workshift+ work traffic) as i constantly surf the web, music, and always checking my phone.
I want something like xperia z3 compact or note 4 battery life, but those phones have some things i don't really like. With the G4, i do plan on buying those high capacity battery (like mugen, hyperion, etc..) if the phone does fall below my expectation.

Mostly wifi ? or is there also same amount of data ? how strong or not that cell data signal is and for how long you are on it will take a toll with any phone.

How bright do you like your screen. if you can manage with less brightness ie 30-50% you can add an hour of sot.
for reference, 3-4h SOT on data and 4-5h sot on wifi only with 65-70 brightness. mixed use means somewhere in between, 4h sot. high brightness means low to mid 3h, less brightness 4-5h.
sot/run times you can expect 3h /9h, 4h/12h, 5h/14+h is normal with stock.
Are these figures you can live with ? xperias & note 4 will give you an extra hour sot on top. that extra hour means 2-4h longer run time.
you dont need to carry those bulky batteries unless your phone absolutely needs to be on, just swap the battery out in a couple of minutes.. Not hot swap, have to power down.
How important is bootloader unlock and roms for you ? some people are forced to stick with original and forego firmware updates to preserve bootloader unlock. this means if any improvements are made in subsequent updates they can't use them and are stuck with whatever bugs are there in the older firmware. Stuck with bugs and waiting for roms can be frustrating.
For some one used to nexus 4 being able to flash anything and everything, G4 might seem a bit boring for you, Nexus 5x ? you dont care for replaceable battery or sd card. just get the biggest onboard memory possible

Yep all wifi, don't have a data plan . wifi signal varies to maximum signal to no signal at all lol. But i do turn on airplane mode when i'm on the train for example. My brightness is set to adaptive brightnes on @ 50%ish
I'm actually avoiding the nexus line in the future lol since i really want sd card slot and removable battery (and good/excellent battery life), usb OTG (particularly usb audio out), and a device that can officially unlock bootloader like the g4 H815. and to be honest, stock android ui is sometimes boring and it never has features u see on like xperia, htc, or samsung devices. And I can just do all my flashing needs on my Nexus 4 when the habit kicks in lol. Overall, on my next phone, i just want options and upgrade/replacement possibility

Then you can expect a 4-5h sot/12-14h run time with normal use. Good enough ?
web browsing won't eat up much battery, its push notifications and constant syncs over weak signal that do it faster.
IMO the g3 was garbage...i had 2 that had emmc failures and all 3 i had overheating issues...battery sucked...only pro was there was a good bit of development...i love my g4...only device i miss over my g4 is my g2...battery life is great with minimal tweaks and greenify...my last run was 5 h 2m sot and 47.5 standby...h81110n

Considering upgrading from a G2 to a G4? What's the battery life really like?

Hope I'm posting this on the right place, missed it and was told by an ad where to place last questions when I asked about another phone.... but of course I can't remember what he told me back then :silly:
Anyway, how is the battery life on a G4? From tech blogs to youtube reviews, opinions are all over the place. Some people say 2 and something SOT. Others claim it's great and that they can go a full day with heavy use and 3d gaming, etc and report over 5 hours SOT with that sort of use.
I loved my G2 for a long time because of how well it battery would last. It's not very good anymore, it went through a lot of charging cycles... Hardware and specs are enough for me, so I don't need the 820 on the G5 nor am I feeling the love for that phone from what I've seen. Especially for the difference on price the two will have and the bargain price one can get some places for a G4.
GSM Arena tools tell me the endurance batery test for the G2 is 81h, a terrible 54h on the G4. Web browsing (more the sort of load I tend to pull from a battery when it comes to SOT) gives it a much more bleak picture: 11:24 for the G2 and only 7:54 for the G4.
Should I trust these numbers? Is the G4 such a power hoarder? Are the different numbers I come across because of some version with or without some update that improved/made things worst?
I'm referring to a non-branded G4, international version. Opinions from real life users would be much appreciated!
Cheers! :good:

Hope I'm posting this on the right place, missed it and was told by an ad where to place last questions when I asked about another phone.... but of course I can't remember what he told me back then :silly:

I have had a g4 for about 2 weeks and i want my g3 back even it seemed better on power than this. My g2 was pbenominal even acter 1.5 years old. This thing but i only have root no bootloader unlock no custom roms or kernals
I made that jump last week.
The G2 was an excellent phone.
The G3 didn't seem like much to me, and I couldn't understand the battery drop-off.
I'm loving the G4, the camera's excellent and the battery life, though not as good as the G2 is not bad at all.
So already I have two different experiences... one that the G3 is better than the G4, another the exact opposite Why is there such a discrepant experience? I know about low signal and constant scanning but I assume those two members above are using their phones on the same region/places/ways...
My G2 battery life is better than G4 at first. Then I turned off two cores in my G4, disabled some settings, and everything seems great now. Good battery life.
Today's battery life on my G4 H815,MM 20d,unlocked bootloader+root+Xposed+Greenify

I had my g3 modded out the gills. Undervolted all linds done bare minimal stock system i could get almost 2 days of moderate usage 6 to 8 bours sot. G4 i love the camera still expiermenting. Im rooted ive managed a few tweaks but not scare of bricking just hate to have to start over. Want over clock undervolt and id be happy. Just knowing i got a locled tight bootloader urks me the most. Its a great phone. Would prefer my g2 over 3 or 4 untill bootloader gets unlocked. I have a lotta quirks on mine i could fix. The battery seems to stay full untill about 12 or 1 then drops at about 1 percent every 3 or 4 min. So i charge off and on throug the day so when i home at night itll make it to bed with like 35 or 40 left
Well, those numbers posted look better than my G2 ever was. But I'm also seeing there's a lot of customization involved to unlock the potential of the phone. Is that why people are reporting such major differences? I must be getting way too old as I no longer find it fun to mess around with phones and PCs, I just want something that works and gets updates that make it better... NO!! This doesn't mean I should go with an Iphone!!
More of a general question... could it be worth keeping the G2 until these new midrange phones with the SD650 or 652 (something like that) start to pop up? I mean, they'll be more powerful than the G2 and probably as cheap or cheaper than a G4. I'm thinking about phones like the Idol 4S.
I've been away from the smartphone market for a long time and I'm having a real hard time catching up. Samsung seems to have turned into some sort of Apple where you pay for the "prestige" of the brand. Motorola has a couple interesting phones but apparently the new Lenovo owner is going to end the brand and I have no idea if that means support. And then these new Chinese phones seem interesting and apparently have good support... Lenovo, Huawei, Xiaomi, etc.
Point being, new midrange is pretty much flagship to my sort of use! It's hard for me to figure out if I even need a new phone! But I would hate to lose the buttons on the back, something that I think only LG owners would get
@Kutusov having read the above, I would seriously recommend the G4.
It's cheap (actually very well priced), still be cheaper as soon as the G5 is released, it's an excellent phone with a FANTASTIC camera.
And it's got the back buttons. In a very short time you'll understand just how far phones have moved in such a short time.
The G2 was spectacular in it's time.
The G3 was refinement but rough.
The G4 blows it away.
Made the jump from the G2 to the G4 a year ago, not disappointed at all
Battery life difference is roughly ~30 minutes worth of screen on time, with the G2 edging out ahead, everything else is just hands down better on the G4 ( excluding the rear facing speaker -_- )
So I'd say go for it, phone's pretty cheap now.
You'll get different results from everyone as we each use our phones differently, different apps and priorities.
If you have social media constantly updating and play 3d games you will need to carry a charger with you, it won't make it through a whole day.
I've disabled most of the bloat, use greenify and get upto 5hrs SOT when reading an ebook from the SD card, but only 3hrs when browsing on mobile data.
Overall I'm very happy with the G4, it would have been even better without the useless 4k screen but there's always a compromise.
I've had the G4 since July 2015 and I'm satisfied with battery consumption(Canadian H812 variant). Not rooted. I disable apps I don't use, installed Lux to control brightness & GPS is only ever used when I need it (rarely).
Per gsam app, averages since last complete charge:
Battery life: 1d 16.9hrs
Screen on: 5hr 48mins

I didn't have the G2, but I'll speak for the G4: the battery is OK.
I usually recharge every 2 days with a normal use (internet surfing, music, watch an episode of a series in the bus, watch the time,...)

Yes, I'll probably go for it. I've seen it somewhere for €330, brand new and sealed, same price no matter what sort of back cover.
I really do like the back buttons, I always go looking for them when I pick some other phone, I would really miss those.
Cheers guys! :highfive:

How did ya disable the big cores?
The only solution I found was a script.
With the custom Kernels I tried they always turned themself back on. But its been a while since I tried one.
And you get the battery life that you can expect from a 3000mah battery with an 5.5" screen at 1440p.
i would like to get one but not until if ever gets bootloader unlocked for US.
i was on a G2 and bought a G4, the battery life is not bad, but the G2 was way better, but, we are talking about a 1080p screen and a QHD screen...there are no miracles ! I am very happy whit my G4, takes very good pictures and for me, the battery gives "juce" for a day, watching movies/series going to the WEB (3G / 3.5G) but i just turn the data when i want, at home, always with the WiFi turn on, so, i wake up at 6:00AM and i get at home at 6:00PM and i still have 40% our 30%.
For me, this is a very good phone !

Yes, that's more or less my sort of use also. I know that LG wanted to come out with a very good panel to demolish the usually praised amoled from Samsung but it sort of sucks that they did. I have no use for it, maybe it's good for this new VR thing but that's something I'm not even curious to try.
Still, it has the quickest charge possible... swapping batteries
guys i know theres lemon battery. but isnt there like an aftermarket one that will fit like normal but higher mah?
