One (huge) factor for battery life I haven't heard anyone mention is their phone's reception. When comparing one person's battery life to another, reception (as well as state of radios, screen, apps, etc) needs to be considered to get any sort of meaningful comparison.

As a demonstration of reception's effects: at work, I get terrible reception--light browsing (maybe 20 mins) on 4g can knock out 10% of the battery. At home where I get fantastic reception, the same browsing might take out 2%. I doubt this changes a whole lot from phone to phone. I noticed on my old razr maxx, the poor reception at work would take a more or less equal toll on the phone's battery life.

And in case anyone cares, battery stats from today:

59% left

9:18 since charge

23% used by screen (time on 1:55)

Phone is on Verizon, unrooted, no GPS, no wifi, moderate screen brightness, and 7ish hours of terrible reception

This!

Trying to catch up to your battery life. I go 2 days on average before a recharge with normal usage. If I did light usage I'm sure I can reach 3 days but its so hard to not use this phone lol
[G2 General] 06stang:
I get 36 hours a charge easy. Love the battery life
[G2 General] WizeGuyDezignz:
Two reasons:

1. I still own my G2 and am currently typing on it and using it as my daily driver.

2. Somebody asked me a question about a phone that I own and am actively using.

In the end, stay out of my business. Thanks.

I'm done with Samsung. But this is battery life thread, better talk about battery life.

Stock G2 have great battery life, but after flashing cleanrom xe battery life is getting better! 9 hours of usage, 3 hours screen on, still 52%. That is amaaaazing!

My battery life is great, aprox 26 hrs with 5 hrs of screen use. My galaxy S3 sucks in comparison with this phone
[G2 General] robogo1982:
My S4 sucked in comparison with the G2. The other day I squeezed out 72+ hours from a single charge. Either it's an app sucking on the battery or your phone needs a reset to settle things down.
[G2 General] jonstrong:
I was actually a bit stunned to see the topic of this thread -- it just struck me as so wrong that I had to check it out. A sense of normalcy returned as I read all the posts about the folks experiencing excellent battery life with the phone, as that matches my own experience. I've been using cell phones for about 22 years, and in recent years various blackberry's, iphones, early "smartphones" (HTC MDA), up through various droids, a Galaxy Nexus (and various experiments with the OEM extended and 3rd party super-extended batteries), and now the G2. The G2, without a doubt, has the best battery life I've ever seen / experienced.

My phone is still stock, locked, unrooted, and I have not turned off ANY of the Verizon bloatware yet. I also have GPS only around the clock, as well as Wi-Fi and Bluetooth. I haven't found any need at all to try freezing apps, turning services on an off, etc. I just leave it all on, and use the phone. A typical day will see me about 50% indoors with W-Fi, and 50% out and about alternating between 3G and 4G.

On the same where I use the phone a LOT, I will see something like 5 hours of screen on time after 13 hours of use, and still have 35% battery left. On other days, I might have used 3.5 hours of screen on time after 18 hours of use, and still have 45% battery left. On quiet days, I've been amazed to be at 75% battery after 18 hours, with the battery app predicting another 36 hours of battery life based on monitoring the last 3 hours of use. This is all standard, stock, locked, unrooted, all apps and bloatware running, no services turned off.

As a matter of fact, as much of a crack flasher as I was with the Galaxy Nexus, I'm hesitant to flash another ROM or go back to Apex or Nova, as it feels that the out-of-the-box configuration is almost absurdly efficient. I absolutely love the fact that I can use the Internet heavily on this phone - via Tapatalk, Hangouts, Chrome, whatever -- and only see modest use of the battery. As a result, I'm doing things with this phone that I would never have considered practical with any prior device. It really is pretty amazing.

If anyone is seeing anything less than superb battery life on a G2, I'd urge you to use a good battery monitoring tool and see if you can find out what app or service is causing this, because this is not an aspect of the normal configuration of this phone. BTW -- lest anyone wonder, I have about 120 apps installed, I have Chrome sync turned on, Google Docs is synced, my photos are uploaded automatically, I'm only using GMail at the moment -- not currently on Exchange with the Email client -- that will come later.
[G2 General] frappe33:
I had a surprising battery issue after a couple months of stellar performance. What I found was that an LG app TaskManager (not to be confused with the normal AOSP task manager) was sucking battery life. Uninstalled it and I was right back to awesome. Just something to look into... hope it helps.
[G2 General] Little Bigboy:
Goodluck with that, i came from the note 3 and ill tell you that the battery is way better on the G2, that big screen is a juicehog.
[G2 General] Sebz4n:
I am just about to charge my phone after 41 hours of usage with WI-FI on and 4G, 3 hours of screen on time.

Coming from an HTC One I find that battery life sexy
[G2 General] rfarrah:
I can honestly say what a relief it is to not have to worry, or even think about charging my phone during the day. With every previous phone, every time I got into the car, or hit the office, the phone had to hit the charger. Not with the G2. I go all day (sometimes 2 days) without thinking about it at all. LOVE it!
[G2 General] kapybarus:
How did you get biggest drain with screen? I thought it is impossible on stock rom g2.
[G2 General] xblackvalorx:
My girlfriend took her s4 back when she saw the battery I was getting on my g2. Girls love to torture phone batteries, she's much happier with her g2.

This is on a fresh flash. Hasn't settled. In that screen time syncing my whole phone and Facebook is included, as well as restoring through tibu and rebooting a few times throughout.

Though it's odd to me, far as we come I'll always remember my htc evo. With decks aosp gingerbread debloated and savagedzen kernel, I could pull 35+ hours of battery with 8 hours of screen time.

Now that would be miraculous on the most efficient devices, and the evo started out awful on battery.
[G2 General] xblackvalorx:

[G2 General] jonsmith709:
Good luck with the Note 3, I had one and had problems, my daughter has also had the same freezing issues. Happy I moved to the G2.
[G2 General] amarinos:
Every single Greek user of the G2, stock or rooted/custom ROM-ed, sees on average 45-50 hours with normal use (everything turned on, 40-50% brightness), almost a full day (24+ hours) with 6 to 8 hours of screen time, and I have personally seen almost 18 hours with game-console-like use. Safe to say, it's nothing sort of amazing ;)
[G2 General] bmoreboy02:
I live in baltimore, MD and LTE is everywhere but i to only could get about 6 to 8hrs of like out of my g2. I really loved the phone but i had to reactivate my note 3. Now i gotta hope i get good money for my g2
[G2 General] gonk24:
You have an app that's keeping the phone awake. 6-8 hours is absurd unless you spent that entire time using it.
[G2 General] bmoreboy02:
All i really do is text and call alot. I get up 5am go to work and by noon when i go to lunch im down to 30 or 40%. I even had a replacement sent. Idk maybe its something unique to my area? Even the htc one i had before the note lasted longer. Also neither of the G2s would stay connected to my air rave
[G2 General] robogo1982:
Could be an issue with signal strength. If you're on the sigbal borderline the phone's radio works overtime to try and keep the connection alive, which in turn absolutely mullers the battery. You should (if you still can) try taking it off LTE and see what will happen on HSPA only. A battery and wakelock analyzer (BetterBatteryStats or Wakelock Detector) could also help.
[G2 General] Steamer86:
I live here too. My house is spotty. Here are some screens with good configs... Not taken in house with low signal though. One is pure stock, everything on, medium-heavy use.

Guys what is WifiOffDelayIfNotUsed thing?! When connected with wifi, this thing runs all the time. It eats battery in sleep a lot especially. Is it normal that it is by far the longest running process in Android System?
[G2 General] Steamer86:
It disconnects wifi on low signal. In wifi advanced turn off optimization and the options for disconnect with no internet/low signal. Turn on Wi-Fi on during sleep - always. If mainly on Wi-Fi, the options are counterintuitive.
[G2 General] JF4W:
Jesus

What are you doing to get THAT much battery..I get 4.5 hours of screen time tops

:(
[G2 General] kikoushi:
Thanks for the suggestion. I've set those that way, but no luck at all. It still is the same and drains the battery(i guess). Here are two screenshots from gsam. Even in 20+ mins with 2-3 mins screen time, the battery drops 2%. For 18.5mins the annoying wifioffblabla works in the background. :(
[G2 General] insang-droid:
I personally like the weather app and the widgit
[G2 General] Steamer86:
Just debloated, some crap greenified along with Facebook and ALL games, some unneeded services stopped through default taskmanager. I leave gps, WiFi, nfc on always. Run BT only when using it. Pretty much, just clean software setup. I still autosync, ect.

---------- Post added at 01:44 AM ---------- Previous post was at 01:27 AM ----------

That's very odd. I see you have a strong signal. Something is holding Wi-Fi open, or possibly, your router is sending keep alive pings. Have you rebooted the phone since changing wifi options? If not, reconnect wifi, and reboot.
[G2 General] ReMiXxXeD:
Dude, this phone is amazing! 5 hours of screen on and still 30% left. Had to charge my old N4 nearly twice a day for a battery life as long as the G2!
[G2 General] jonstrong:
Hi It really is fantastic -- I've been off battery 13 hours, spent an hour and a half with screen on, and I'm still at 72% with a forecast of another 27 hours of battery life on this charge. When I need it, 5 or more hours screen on isn't a stretch at all.

I'm also really enjoying the stock software (aside from the VzW bloat). I love the weather / cloud /daylight animations over the lock screen when I wake up the phone -- and the way they change based on time of day. Also like the weather in the combo time / weather app -- very nice for a change, and again -- I love it changing throughout the day. The launcher is very nice -- first one I've liked aside from Apex and Nova -- excellent animations, great the way I can see the pages while I'm selecting apps and widgets to drag onto them -- only thing I miss is the ability to define up and down swiping actions, but with everything else I'm getting that's not a big deal.

Best phone ever.

EDIT: btw - I was considering the need to root so I could debloat the phone. Turns out that the standard Android app manager can disable just about all the VzW bloat. I think there might have been one or two it couldn't disable...nothing significant.

Then, you can use the app drawer feature to hide / show apps, and hide all the disabled ones. The only downside is the space these still occupy, but it's pretty negligible on this phone. So...plenty of reasons to still root, but if your primary objective is just to debloat and disable carrier specific apps and services, it's easy to do in pure stock, unrooted.
[G2 General] Itchiee:
Chiming in if i could... I just looked at my Sprint G2 and i have 16+ hours usage, with 3hs/15 minutes screen on, and 65% battery remaining. Oh this has been with LTE on the whole time, and crossing the state of Florida earlier today to visit family.

So, no battery life isn't bad on this phone!
[G2 General] hudarsono:
Strange, as I am on stock and it is the best phone for battery life, 2x longer than my old galaxy nexus.

I am mostly on WIFI in office and home. It will last about 2 - 3 days. So I guess my usage is not heavy, but with heavy usage, it would still last at least 1,5 days.

May be you could try to disable unused background service from the vendor? For mine, i disabled few services, such as LG stuff, and something like Slide Aside service, which always running, and seems pointless for me.
[G2 General] nrage23:
I use my phone for a lot of stuff everyday. I take of the charger at 5 am and plug it in around 10 pm. It is always above 50% when I do. The battery life on this phone is phenomenal.
[G2 General] ayman86:
got 8 hours yesterday. on lte all day. pretty much yahoo sports app and yahoo fantasy sports app. mixed in with facebook, chrome and hangouts usage.
[G2 General] heymoe:
No issues with battery here as well. The G2 easily gets me though a whole day and then some under my normal usage. I did recently have a morning where I pulled the G2 from the charger an started surf for a while and noticed that it dropped to the low 90s by time I was done. I didn't think it was going to last the rest of the day but it did.

Guys I need help with calibrating my battery. I'm on a LG flex port and I'm not a noob to battery stats yet I'll post some pics of what's draining my battery. Every time I use a stock based Rom I get sh*** results. Usually 4 hours of screen on time and 10 hours of usage. That's not good for this phone including I have an 3000mah battery. When I use a stock based rom it works perfectly! I get like 5 hrs or 6 with 20 hrs of usage because I can change the location service. I think personally it's with location that's killing my battery.
[G2 General] xblackvalorx:
Try turning location off see how it works
[G2 General] Ponsonby_Britt:
Usually battery life is lengthened after several discharge/charge cycles; the owner's manual for this unit says "The battery must be fully charged

initially to improve battery lifetime."
[G2 General] m.cassedy:
It's good to use as much of the battery you can before charging it, I think.
[G2 General] edwrech:
Well, it seems that mileage may vary, but certainly better than 2.5 SOT I have on my Galaxy Ace.
[G2 General] Sean473:
Anything is better than Galaxy Ace lol... How can you even compare the 2 of them? :D
[G2 General] Steamer86:
Just precautionary to have best calibration at first, it resets itself anyhow. Not needed.

Wrong, if anything try not deplete past 5%.

The only thing that will noticeably degrade these batteries in a year with standard heavy use is heat. The former being second most noticeable, but at over a year, you won't even notice that to eye. Of coarse other damage is a different story. Charge them, leave them, quick cycle, doesn't matter. The logic is very smart.
[G2 General] saltynut1:
Flashed the debloated stock rom, and all I can say is the battery life is definitely amazing. At first, I was a little disappointed because the battery life was no better then my old iphone 4, but now it's simply amazing. Definitely something in the stock bloatware that wrecks the battery life.
[G2 General] m.cassedy:
I was referring to the initial discharge from earlier post. From what I know, fully charge, then for the battery memory, discharge to under 20%. This way the full potential of the battery is kept in memory. You only need to do this once in a while, never repeatedly. Keeping the phone from over heating is most important, I agree.
[G2 General] VanHelsing8:
Had a crazy screen on time today, over 10 hours, on 55% auto brightness, even used tethering for about an hour.

Using stock rom, rooted and debloated.

View attachment 2480290
[G2 General] jonstrong:
Good to see this. For those who have chosen to *not* root yet, or are rooted but still on the original stock ROM, you can also simply go into the Application Manager and disable all but one or two of the preinstalled bloatware apps. Once that's done, you can use the stock launcher feature to hide each of those disabled apps. On a lesser phone, I'd worry about the space these disabled apps take up, but I don't anticipate running out of space with the phone any time in the near future. Net: aside from recovering the storage space used by these disabled and hidden apps, you can achieve just about the same savings in CPU / radio / syncing function as you might accomplish by installing a debloated ROM.

This is NOT to say folks shouldn't use a custom ROM -- that's one of the core activities here at XDA. Just offering an alternative for those who actually like the standard stock ROM.
[G2 General] Steamer86:
There is no battery memory. Calibration happens upon reboot and or self calibrates. This is why once and a while you will see a percentage loss. You never need to do it. These are Li-Po batteries, not old Ni-Ca ect. Unless you have some crazy software issue going on or faulty hardware, the phone won't really overheat even on charge. Overclocking and ramped up kernels with no throttling is a different story.
[G2 General] OptimusL:
Nope stock battery life is fantastic.
[G2 General] JF4W:
How in the world do you get 10 hours of screen time??!?!?!!?!?!

First cycle
[G2 General] VanHelsing8:
I was a bit shocked myself, i usally get between 6 and 7 hours.

Probably because I've read an ebook for a few hours and the phone was only for 4 hours on standby. But no specific power saving, like I said, 55% auto-brightness (stock), mixed use of wifi/4g, gps/nfc/sync on etc.

No point. batterystats.bin simply holds use statistics since unplugged. Charging to 100% wipes it anyway. This whole battery stats bin thing is a long standing myth debunked by an OG Google dev. It has nothing to do with calibration or your battery % notification for that matter.

[G2 General] hasenbein1966:
Guys.

It has been repeated in different places and on different occasions that the G2 has Graphics RAM (gRAM) which means that the GPU doesn't need to refresh the screen all the time when the screen contents is static.

This explains why in the battery statistics the screen is so low.

And it explains the huge differences in SOT between users.

A users who mainly reads or does other things where not so much is happening on the screen will get very long SOT.

A user who watches more video, plays games or does other things where the GPU is in action will get lower SOT (sometimes MUCH lower).

And of course the battery usage of the CPU also plays an important role... Reading epubs = low CPU, browsing fast through different websites in a ressource-hungry browser = high CPU...

So these differences are perfectly normal with the G2, and I hope you see that all these discussions here are totally useless.

The only thing that is worth investigating is whether the standby battery usage is OK or whether there are unnecessary wakelocks.
[G2 General] samleung:
