Sounds like you might have a bad one! I can go well over 24 hours with heavy use. Actually, i get about double the battery i got out of my iPhone 4s. Besides the billion other things that are better about android and this phone, the battery is probably top three list!

 

Well, check out in the Galaxy S4 forum but I think LG G2 got better battery life. You can change battery on the S4.

 

If you have not already done so, try performing a Factory Data Reset (FDR) on your device. When standing by or in use, this device should crush an iPhone in battery charge longevity comparison.

Honestly I suspect something is misconfigured on your device. Your experience is not representative.

 

Something def sounds wrong there

If a factory reset doesn't solve it, I'd look into getting it replaced, as you likely have a defective unit

 

The battery in your phone has to be defective. I easily get more than a day of battery life with my G2. Much better than with my S3. The G2 is much better than the IPhone 4S you had. You were just unlucky to have a bad unit.

 

Definitely go change it if you can.

 

That is definitely not right, I agree with the others get your phone replaced your battery must be faulty.

 

+1 on changing it if possible especially since you've already tried factory reset to no avail. I get 2 days with average use and 3 days with light use. Very atypical stats you're seeing. The battery in the G2 is one of the longest lasting for any phone Android or otherwise. Something is amiss.

 

as for me on stock I get about 2+ days of moderate use.... minimum 50 hours......... after root and custom rom I can usually go about 70 hours on a charge with moderate use....and thats because I dont let a phone go below 30% before charging typically...... dont want to get stranded

*daily moderate use being about 2 hours web surfing........ facebook updateing...... wifi and 4G on all the time...... typically 30 mins of streaming radio...... constant weather updates (weather is important in my tiny little realm).... tapatalk(forum browsing) about an hour each day....nothing extreme.... just moderate useage


if you are getting less than 24 hours even on heavy useage I would say you have a bad one......... something isnt calibrated properly or that battery is junk........ time to visit the store

this phone is easily among the best.... if not the single best...... for battery useage on the market...... and definitely leaps and bounds above any Iphone even if the iCrap is turned off

 

then a store visit is in order....... this phone should make you believe you had an early days dumbphone with unlimited battery

 

Yep there's a reason this phone was praised for its battery life, its fantastic. I think at worst i've gotten 5.5 hrs of screen on time.

 

Get it exchanged ASAP, i own the G2 for 2 months now and NEVER had any issues. I've researched all the forums before buying it and i know what may or may not happen. Yours is definitely defective : some kind of short on the motherboard, defective battery or one component is defective and is eating more batt than it should !

I can easily guarantee that until now this is by far the best phone and has the best batt life of all devices i owned.

Last test i made : 79h after a single 0-100% charge and using : 15-20min/day of Facebook + 20-30min phonecalls/day + listening to music 1,5h/day + playing Asphalt 8 about 30-40min/day.

 

My LG G2 has the best battery life of any phone I have ever used. I try to kill it during the day and I end up running out of juice before this phone does. It's a beast.

 

Sounds like you may have had a pretty nasty wakelock

IE some app was keeping the device from sleeping properly

 

i have a free app i downloaded from the play store i use called watchdog lite. if anything is eating too much battery life it will tell/warn you what it is. worth having in your situation.

 

Even with the bloat, I've found the battery life to be better on the stock ROM than AOSP ones like Cyanogen. That said, it's still extraordinary and I love it.

 

yup this phone has a beastly battery and anyone complaining about battery life on this phone is one of two things....impossible to please, or has a defective unit.

Shoot! I even read an article talking about how in real world test and usage the g2 outperformed the droid ultra whose whole marketing is based around it's amazing battery life.

 

I think there are some other potential user pools...
1). potentially those that need to perform an FDR and start configuring the device from scratch. I think it's just too likely that a bad software starting point because of memory location initialization might result in a service or other program running in a rogue manner.

2). those that accidentally configured the device to use way more battery than they should (say a very quick email sync interval and other stuff like that).

3). those that live on the fringe of 4G coverage, and the radios are cycling 3G / 4G (I think this could contribute).

Defective unit? Yes, it's possible some have a marginal cell. The miniaturization / complexity of the battery itself probably results in a distribution with outliers far from the mean.
