Why I think battery life sucks so bad...

I usually have a multimeter on my counter for my ecig mods, and, since I change batteries pretty often now that I have spares for my thrill, I'be been randomly checking thier voltages. What I've found is that a "dead" battery is at ~3.7V. That's not dead. These phones should discharge to something like 3.2V. Anyone have any idea as to why they would read nominal voltage as dead?

After few more charges, it discharges to about 3.43V, still high I think, so I'll keep an eye on it.

What you're saying actually makes sense. The system has to calibrate itself to the battery. This is why battery life tends to improve over time as you discharge and charge the phone. There are ways to kick start the process but eventually it will do it on it's own. My battery life has tripled after a couple weeks.

i am wondering why i have fully charged and discharged my phone numerous times and my battert is horrible. its gotten worse. i unplug it with 100% at 5:30 a.m. its now 9:40 a.m. and im at 62%! i have sent 2 text messages this morning and my app manager has no open apps. Why would my battery be so bad? i have had this phone since the day it came out and love it. im not real familiar with all the "rooting" or all this fancy stuff but i do know that the phone should have a better battery life than it does.
Does anyone know what i should be looking at to see what is killing the battery so fast. almost 40% in 4 hras and i havent even used it?
thanks.

Try installing a ROM that removes some of the services that a stock rom has this way will save your battery time a lot

I have installed several ROMS i am new to the LG Thrill but with my previous HTC G2 y used cyanogen but as per this is a 3D phone cyanogen is not ready yet. But the best rom i have tried so far has been the thriller
http://forum.xda-developers.com/showthread.php?t=1261704
although is missing good things from the newer firmwares like the 3d app converter.
But i'm ussing the thriller Rom until LG releases the Gingerbread official update that comes with great new stuff

Here's what I've found out about the battery. It's apparently a known issue by google addressed in later updates.
Here's a great method to work with it for now.

This mine with 48% battery life left. I found out on mine if you play one of the 3d games and don't exit out of right it continued to run and eat the battery. I use wifi where ever it is available. Always leave it on unless I am on the road then I turn it off so it won't be hunting for a connection. Have gone 28 hours and have 30% battery left.
Had phone since September 4th and battery life has improved tremendously. Stock and unrooted.

My phone is stock and unrooted as well. i charged it this morning from completly dead. started to charge at 6:30 am and took untill almost 11:00 before it was a 100%. now it is 1:30 pm i have sent 1 text message and thats it except meybe waking it up to see if i have missed calls or txt and my battery is down to 44%! 2 hrs really? i have not used it. Wifi is on but should not be sucking that much juice. i trashed the yahoo news app. my weather app is set to update manually. i dont have anything special done to my ohone like all these forums suggest the "rooting" or special rom's. it pretty stock.
I have used the battery calibrator app and it didnt seem to do anything for me. anybody else have other suggestions? i basically get about 3-4 hrs of battery life berfore having to charge unless i use the phone then i get about 2.
oh yeah and my wife has the same phone, some battery issues but i think her's is normal. so to see if it was the battery or my phone we swapped batteries. my original is in her phone working fine and i have her's and still crappy so i know it wasnt just a bad battery.
what do i do next??

You could install CPU spy from the market and see what it is showing you. See if it ever gets into deep sleep mode. I also use battery monitor widget from the market to see what all is using battery.

Haha. Yea, he's showing that his battery meter is not accurate. Lol.
I lasted 3 days and 9 hours with my $10 extended battery. It was at 1% for a good 36 hours of it.
On my standard battery after 16 hours of "normal to light" use, I'm usually around 60%. As long as I don't have to charge it during the day, I'm happy. Plug it in every night when you go to bed and unplug it in the morning, you will last all day.

lmao wasn't the planning on that ill give a more accuarate battery in a few hours i actually went from full at 12 pm to about 5 brinking me to 10 percent in 5 hours

Other than the incorrect meter LucasMN, how much better is the extended battery in terms of single full charge. I am debating on getting an extended battery because I use my droid heavily throughout the day for work. I charge with the same habits as you. With my current standard battery I get to about 50% by 2pm (my day starts at 8:30a)

I cannot compare it to the standard battery as I've never let the standard get lower than 30%.
3 days and 9 hours on the extended battery included 2 full work days. I work in IT and will quickly check e-mails throughout the day on my phone. Out of the office I use it quite a bit for facebook and streaming music. 95% of use was over Wifi though.
I bought the battery + cover off ebay for $10. It's about 3x as thick as the original battery.

So I was a bit concerned about battery now seems to be pretty good strange how some days I get 5 hours to 20 percent now going on 7 at only 50 percent

Can't post screen shot since phone is stuck at motor screen atm, but...with a dim screen, cal'd battery and debloated rom , I can burn through a full charge OEM extended battery in half an hour or less. I use a ton of SMS...

a half hour for a extended battery are you freaking kidding me and i thought this was bad i sms a lot too facebook and xda mostly through the day that is just crazy i am still at 50 percent and now at 7 in a half hours looks like i might make it to almost 12 on this one

when I get to a PC and unfutz my bionic ill screen shot it for you. To be honest I have always been a battery abuser though. BB curve to storm to og Droid to d2 and now bionic...all had to have extended batteries.

I would love to see this. With my extended battery, I stayed at 1% for over a day though. Unless yours is powering off, I bet that would be the case. 30 min for an extended battery, even an OEM standard battery sounds like BS to be honest, unless it is physically damaged.

I don't know what happened to mess up everyone's battery life, but when I flashed the 904 update mine all went away!

4.2 battery life.

I think it's obvious there are some serious flaws with 4.2, everyone has made that evident. I just wanted to ask you guys what kind of battery life you all are getting out of your N7 with the new 4.2 update?
EDIT: Im not so much worried about the battery life regarding 4.2, just battery life in general. Ive got everything turned waaay down and am only getting roughly 20 hours with moderatly heavy use. What do you guys get?

Same as 4.1.2 I believe. I can't tell a difference.

I actually haven't had any issues as of yet. Been running it only a week. I did update all the apps right away, which a lot of people that had problems related them to the apps.
Haven't had one force close and battery life has been right on par with 4.1.2.
Sent from a galaxy far away!

So far mine has gotten better. I cant say for certain this is due to 4.2.1 however since I switched ROMS and Kernels to get it. But it certainly hasn't gotten worse!

Getting two days out of it which is perfectly fine with me. I get the same out of my Asus Transformer Infinity as well. Seems reasonable to me. What type of battery life were you expecting our need? Can't find a time to charge in a couple of days or something?

Ohh ive got the time. Was just curious as to what other users were getting. Guess i just expexted more battery life outta the N7. I usually get one solid day of use out of it, granted i do use the hell out of it and so does my girlfriend
Sent from my SAMSUNG-SGH-I717 using xda app-developers app

I think that the batery life when you flash 4.2 is very badly.

I generally charge daily due to extremely heavy use, a few hours worth of gameplay while at work and use as my primary computer while at home. But I have went as much as 3 days with just light browsing here and there.
Sent from my Galaxy Nexus using xda premium

My battery life hasn't been that great when i was on 4.1.2 i lost like 1% over night now im losing like 15% even tho i just charge it up it seems thats its the Android os and google services thats killing the battery. I never had that much battery drain untill 4.2- 4.2.1
Sent from my Nexus 7 using xda app-developers app

I've got to say mine's far improved... To be honest I've now set WIFI to off when in standby and screens always been down to 25%, so I'll get 2-3 days out of it with average use!

EVERYONES battery usage is going to vary... Wifi on during sleep with media syncing etc etc.... Is going to be much higher than me turning off wifi on sleep and not that much stuff running, etc...
My N7 is still at 100% if I take it off the charger at 9am and don't pick it up until 1-2 in the afternoon, which happens sometimes when I'm busy at work. There have been days that I didn't touch it all day at work and got home at 6pm and it's still at 100%.
In actual use (news, browsing, etc, not games) I see about 13-14% battery usage an hour, depends on the backlight. Games or movies, more like 16-17%.
And I've seen no obvious difference between 4.1.1, 4.1.2, 4.2, 4.2.1, etc....

My battery life so far has been amazing.
I always make sure it is fully charged when I leave my home at 7am. I have syncing, wifi and gps always turned on. While traveling I watch videos most of the time (around 1 and a half hours video screen time in total). During the day while working I use my N7 for web browsing, social media, taking notes, agenda stuff, etc. Most of the time I'm home around 6pm. Then I have about 60-70% left. I'm using stock 4.2.1, no custom kernels, root or roms whatsoever right now. I could make 2 days with quite some heavy usage, which impresses me a lot.

Took a screenshot of the battery run time. This is what I'm getting with basic web surfing and watching YouTube.

Battery life has been good so far. I'm running a 3G Nexus 7, as said previously though it is all relative to what you're doing with your device.

12hrs of moderately heavy use for the OP, and he's complaining about batt life?
Isn't the batt on these things only rated for 10hrs anyways? Maybe I'm missing something here. Google states 10hrs for reading a book or browsing the web, and only 8hrs for 720p video.
OP - i'm sure your batt life went down, but you DO realize that you're already getting more than it's rated for, right? There's so many factors that go into determining batt life, that's it's impossible to give a realistic figure.
Who knows how many apps you have in background, your WiFi signal strength, brightness of display, etc.

My battery life had been crap since day one.

Light day today, off the charger at 9am, this screenshot taken at 6:10pm. Used for 30 minutes according to the screen on timer, about 20 minutes of that was doing something on a server in irssiconnectbot and the rest was probably "glance at the weather" or "next meeting" etc.
It was at 100% around 2pm ish when I was in a meeting using irssibot, it dropped 3 or so percent while I used it there. I've never noticed this, but if you look close under the graph, it appears to have an bar for device awake, although it's dark blue and thin.

Getting good battery backup [Not Rooted][Review]

Hey,
It's been 2 weeks since I got my Black 32Gig Nexus 5, I was a little bit afraid about the battery backup of N5 from reviews, every reviewer pointed out that N5 battery is downright bad but after getting my device I found out that N5 battery is NOT that bad but actually offers good backup :fingers-crossed: , the funny thing is when I charged first time and used my N5 it went down after just 5 hours with SOT of 2 hours !! but what makes me wonder is that after my first charging backup starts to increase !! I don't know why is this happening but battery backup actually increased noticeably day after day, I just don't know how this is happening may be battery is taking time to set up, I know first days we use our device with everything turned on thereby draining battery more than after getting used to but I can confirm that's not the case, backup is actually increasing. I have attached images of my current backup+settings.
Battery Status
Total time on battery : 20 Hours
Screen on time : 5 hours
Settings
Not Rooted.
Brightness: 20%(Approx.), Auto was too bright.
Location : On all the time with Battery saving mode.
WIFI: On all the time
Data: On all the time(HSPDA)
Bluetooth/NFC: Off all the time(I didn't had a chance to use it)
Google Now/ Location reporting : On
Vibration on typing(Key touch): Off (prolly most don't care about this but a big battery drainer)
Usage
30 mins of phone call
30-40 mins of web browsing with Chrome
30 mins of gaming (Temple run and NFS)
20 mins of music
Couple of photos taken
Couple of apps downloaded with playstore etc
I know battery is NOT a pro side of N5 but 20 hours is all I expect from a quad core smartphone !! also backup is really not a dealbreaker for Nexus 5.
My humble small review
Cons (That would go first)
Speaker - This is the biggest problem and a "can be deal breaker" con of N5, I never expected BOOMSOUND from this phone but current ouput is downright bad.
Camera App - Sucks big time, lot of time to focus etc but don't take me wrong image quality is NICE.
A bigger battery would have been better (Not saying current backup is bad)
Button rattling, negligible but shows production carelessness.
IR Blaster would have been nice, It's kinda asking a lot for $350 device it would have been a bigger plus since Kitkat is natively supporting it.
Pros
Everything else than cons about the phone are huge pros :angel:

While I haven't seen any crazy battery life from this phone I have been getting 4½ hours screen time with 20+ hours on a charge consistently. After I figured after that touch sounds were causing a bad wakelock I was having the first couple days.
So I'm perfectly happy with battery life, its an improvement over my G'Nex and that's on LTE the entire time.

Standby drain

When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the LG V20's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!

Compared to the Note 7 there is next to zero residual battery drain. I forgot to plug it in one night and saw a 2% drop.

Doesnt really drain on sleep mode. Not bad.
Sent from my LG-H918 using Tapatalk

This is great to hear. My V10 can drop 30% overnight. I can't wait to upgrade.

I'm losing upwards of 15% at night. Not good.

This has been one of my BEST PERFORMED sleep time phone so far! Must be something w NOUGAT also? Love it!

I noticed sometime when we insert a new sd card the phone needs to create an internal list and this process can suck alot of battery. It might or might not be this issue thats causing some users to experience overnight battery loss.

I got my V20 yesterday and had it sit overnight, and the drain was practically zero. Very impressed so far.

Standby drain is beyond great. If the phone is off, then 0 to 1% is lost, depending on the stand by time.
Sent from my VS995 using Tapatalk

The standby drain is unbelievable. I've noticed between 1-2% drain per hour. That's with bluetooth, wifi, and location on, as well as android wear and google fit constantly running in the background.
It's WAY better than my GS7 Edge.

So over an 8hr night you would lose 16%? That's not gifs at all.

I just got the phone last night. First of all... damn this is a sexy beautiful phone. Sleek slim as hell and the best phone I've owned thus far.
What is not okay is the battery drain in standby. I put it on the nightstand at 100% at 11:30pm, woke up at 6:30pm (7hours total) and it was down to 40%!!!!
Not okay LG. I moved over from the LG G5 and the standby on that was excellent, would still be in the 90%s , I hope an update is issued to fix this problem

Over 6 hours of stand by time with 0% lost. I have 4 email accounts running, a few game notifications, etc... No facebook.
This was taken after I cleared most of my notifications.

I too have noticed that this phone has significantly less standby drain than the S7 i was using between the Note7 return and the V20. All in all just better with the battery in my opinion. I usually listen to Pandora all day long at work (wired) and then use my BT headphones at the gym for a couple hours each night too. With the S7 I had to recharge the phone near the end of the work day or i would be cutting it close by the end of my workout. Not the case at all with the V20, after my workout im around 45% still. I do have 2 email accounts / FB / bunch of other stuff running at all times too pretty much. Get a lot of calls / texts throughout the day of course too. So far it has been amazing

I Have the V20 for 2 days and last nite lost about 30%, will check today what was running... not good but could be the battery ....

Sleep mode is awesome I bearly notice a drian.

7 hours I slept last night with v20 unplugged after fully charging. Burned 1%.
Your issue seems to either be low signal strength or apps waking the phone.

I am havei very little sleep drain. This phone has really surprised me. I have been loyal too thenote series since the n2.... And when the n7 issue started and we had to return it I decided to give the v20 a shot. So far it has really surprised me!
