Help S5 Battery Gripe

Over the weekend, I had charged the phone up to about 90%. I used it a bit and then fell asleep without charging it. I went all day Sunday without charging. Other than the 7 hours of sleep...I used the phone a good portion of the day...granted a lot of that was on Wifi and not over the 4G LTE. The phone lasted 23 hours and dropped down to about 16% when I finally put it back on the charger before going to bed. Again...I used the phone all day long. I am very happy with my battery life.

Today at work, I used the phone a little bit...but not a ton. The phone was at 100% when I pulled it off the charger. It's been about 9 hours since I pulled the phone off the charger and my phone sits at 83% charge. Today was a mix of Wifi and 4G LTE...probably about 50-50. Again though...I pretty much just used the phone to check the occasional e-mail and a couple social networks and text a couple friends. I didn't use it nearly as much as Sunday.

I got mine Friday afternoon and ran the battery completely dead.

I plugged it in at night and unplugged it Saturday morning once I was up and around. I have been using it - setting it up, looking around, browsing the internet, texting, calling, Flipboard, downloading new apps, etc - and as of right now I am at 56%.

For me that is great. WAY better than my S4. I do not think I will have to plug it in until sometime Monday.
Just plugged it in now so I got about 60 hours out of it. WAY better than my S4.

I would need 4 batteries to last that long. Mine burns through the battery twice as fast as my S4.

Burning twice faster than S4 doesn't sound normal at all. Can you post your battery stats screen to see what's going on?

You can try factory reset without installing any apps and see how it goes. If it's still the same, you probably got a lemon and needs to exchange it.

The photos below are from my 2nd day of use of the Galaxy S5. I played 2-3 games throughout the day. I used a good amount of wifi/4g and whatever I wanted.

I know that battery life is a hard thing to be objective about because nowadays it is all about customization and what gadgets are working.

This is exactly my normal daily consumption. With the Galaxy S3 I would have to charge it every 8-9hs.

The 2 big gaps on the battery screen are at night while sleeping.

Mine has a battery comparable to my iPhone 4. Used plex and did some internet browsing for 4.5 hours last night, started at 75%, went down to 23% by the end of it. Fell asleep for 10 hours (the flu is fun), woke up with it at 10%. I'm going to try letting it run down to 0% from 100% five times to see if that helps. Here are my battery stats.

I have no gripes with the battery so far. I'm at just over 13 hours off the charger and still at 54% under normal (for me) useage. I did notice today that the Verizon Cloud settings were defaulted to backup hourly, so I turned that off. I'll be interested to see if that boosts my battery life even more.

I have had my phone since Thursday 4/10 and I have kept it plugged in and charging while I setup and familiarize myself with it.

I can not keep the battery charged while in use - this morning from 100% and a sync with contacts dropped it by 15% even while plugged into the wall outlet.

Yesterday I made 2 calls average time 11 minutes each with battery power save mode on. I left home with 98% at 6 am and by noon i was down to 40%.

Seems we need an update to the OS for battery management?
This battery will not make a full day!

Specmanship and bull $#\€ marketing lied again.

I expect or need 8 hours plus and this so far Is a 4 to 6 hour phone. Bottom line you need the high watt brick/plug and cable for a wall charge with you. It barely charges on the USB cable to my late as a back up.

I am disappointed.

I think for whats expected on a smartphone, its not bad. I can make it my whole day,16 hours about 10 hours no wifi and still have 20 some % left. Old Galaxy Nexus was always on the charger.

Thats with random social networking, calls and texts, about an hour streaming music, and multiple 2-5 min sessions of Clash of Clans (damn clan wars!)

I unplugged my phone from the charger Tuesday morning. Used it all Tuesday and Wednesday. Many phone calls, texting, took pics, internet, flipboard etc, downloaded updates, and played around with the settings.

Now on Thursday morning I am at 10%. With my S4 and the amount of usage I do not think I would have had 10% left Wednesday morning.

YMMV

My first day of usage gave me horrible battery results. After 10 hours of phone usage (maybe less), on the first day, it was under 30% when I plugged it into the charger when I went to bed.

At the end of each day (I got the phone on April 11), the battery remaining % keeps improving. Last night, I had around 50 or 60% battery left.

I think this is an Android thing. Doesn't the OS effectively "learn" as it goes on and shuts down some tasks that aren't being used, etc, etc...? I'm wondering if that's helping to give us (or at least some of us) better battery performance?

In theory, That sounds like a good one. But that wouldn't explain why some people have amazing life out of the box.
Is definitely to do with the phones rather than the batteries. I got a new battery yesterday and it is no better. Not worse. Just the same as the one is been using for a week

I suspect there is disparity between battery usage mileage because there are different takes on light vs heavy usage. Battery usage stats will tell the story better. 3 days of not using a phone defeats the purpose of having it.

Take me for instance. I'm currently sitting at 50'ish % after 15 1/2 hours.

However, 1hr 35min with the screen on (full brightness.... Accident), android OS awake for 1hr 19min, android system for 1hr 30 mins.

The phone did stay in a metal lock box for 10 hrs today, so it spent a lot,of time searching for a signal.

So by my estimate, I only really had about 1 1/2 hours of continuous use.
