Help Battery Issue

Hey everyone,

After extensive research, I decided on purchasing the LG G2, as it is noted for its big and beautiful screen, fast hardware, and incredible battery life. The first two, in my opinion at least, have come as advertised. I am, however, actually worried about the battery life. I have used it non stop all day long (about 6 hours) and the battery is already at 8%. I noticed that the battery was not fully charged when it was being setup at Best Buy today - but, is this something I should be concerned about? In almost every review, it stated that the LG could handle a full day (if not more) of medium to heavy use. I was not even doing anything that would really tax the phone either (the most was downloading about twenty apps which took only a few minutes). I spoke on the phone for about thirty minutes and sent out a few texts, but I did not watch any video and spent minimal time surfing the web. Is it necessary to run the battery all the way down to ensure the battery fills back to its "full potential"? Again, many of the reviews raved about the long battery life from the initial setup.

Thanks in advance,

Tom
 
First thing to do with a new cellphone that doesn't have a replaceable battery. Have them plug the charger in before turning the phone on. After they have the phone activated, turn it off and take it home. Plug in the charger and leave it charging (amd off) for 24 hours. Then unplu ght charger and use the phone normally until it tells you to connect the charger. Turn the pjhone off and charge it for 24 hours. Repeat this cycle 3 times. I have 10 year old batteries that still give me full life. I know the "standard wisdom" says that this is the wrong way to treat LiIon batteries, but it's worked for me since LiIon batteries first came out. (I don't buy phones with non-replaceable batteries, and I don't let them activate the phone with my battery at all.)

It's a bit late now, but you can start the first full charge cycle tonight.

I would say that you need to do a reset on the phone. I had the same issue, I also had a problem charging the phone. It only showed that it was charged at 80% even though it was plugged in for 8 hours. Once I did the hard reset, the battery life improved drastically. I usually do a reset once I get a new phone right away, but for some reason didnt do it on this one.

On my first full charge I got:

6+ hours screen on, mostly browsing over wifi, some app installs, light gaming
30-ish minutes talk
30-ish minutes in wireless storage mode copying MP3s from home computer
1.5 hours listening to locally stored MP3s

This was over the course of 3 days (66 hours since charging)--airplane mode while sleeping at night, wifi when at home and at the office--so a fair bit of cell standby as well.

The battery is a beast. If you're getting significantly less battery life there might well be something wrong with yours.

Thanks to everyone for the reply. I think I will be returning the phone for a new one. I have been trying a few things (battery app saver, lowering the brightness, no wifi, etc.) and still similar results. I will try the airplane mode at night - that is a great idea. Thanks again for the feedback!

What brightness do you have on your phone? I always have it at 40% which is not exactly bright and the max i can get is 5 hour screen on time while browsing and twitter.

40%. I use a SwitchPro widget to set brightness, and in the toggle settings the options I selected are 100%, 70%, 40%, 20%. 40% is comfortable for me indoors, which is where I spend most of my time with the G2.

You might be doing something more demanding of battery power with the screen on. Maybe the Twitter app uses more battery or the sites you browse are more data heavy than mine. Perhaps something else in the background using battery. Could be any number of things, but I think 5 hours screen time is still good. Over the course of 3 days I'd be lucky to get 3 hours screen time on my Galaxy S3, usually more like 2 - 2.5.

5-6 hours screen on time is about average fir this phone.

My iPhone gave me 3:30plus horrible standby time.

This G2 has awesome standby time, so 5-6 hours of screen on time translates into all day heavy use.

If you're using data it will kill the battery in any phone.

I've been online here for 2:07hrs straight and I'm at 68%. Time on battery is 2:30hrs, so I've been constantly online since i woke i up.

At this rate I'll get about 7hours of screen on time. That's amazing for a 1080p 5.2" quad core phone.

FWIW: Unit has been on battery for 12.5 hours and I'm down to 81%. I've streamed Pandora on a 40min drive, watched a couple of YouTube videos, sent a number of messages and emails over 4G, taken a few 5-10min phone calls.

The thing that dropped the battery the fastest was when I was streaming Pandora (both 4G and BT radios in operation).

My LG Spectrum would have been begging for a charge at this point.

I'm very happy that this thing can give me a full day at work and more.

How do I determine screen on time?
