Quick Battery Drain/Death - Samsung Galaxy S7 Questions and Answers

Hello all,
I am having issues of late with battery "drain" for lack of better terms. I have attached a battery log I installed after the 3rd time this happened.
The battery is going from a large amount (most times) to dead in the space of minutes.
Wednesday 9/20 - somewhere around 8:15 it was at 50%.
At 8:50 the phone died.
9/20 again 10:25 pm - 13 %.... at 10:30 the phone was dead (no use)
9/21 around 5 pm it was 60% ten minutes later dead.
It did it again tonight. After the 9/21 discharge I installed a battery logger to see what was going on.
At 9:55:34 it was 47% at 9:55:50 (less then 20 MILLIseconds later) it was at 14%....
I have had battery drain before with programs and services in use, but nothing like this. I don't understand it... this is different. This seems to be something else. Nothing has changed. No new installs. Nothing seems to be using the battery more often. And even if it did, from 47 to 14? That's drastic.
Any ideas? From what I've searched I'm not seeing this type of drain. Just usuage drain.

What more needs expanding about that post? Your battery is at the end of it's life, it's done, get a new one

Don't be stupid, dude. That's impossible, because the S7 has more or less 1 year of life. But that's strange to see a decrease of 40% in 10 minutes.
Probably the battery is defective, not exhausted.

I've had the phone since April 2016 so it could be reaching its life (which would be annoying since they do 2 year leases. Lol)

But our battery lasts many year, depends on your use. If you Quick Charge 2-3 times a day, it's normal.

Sometimes more. And about 75 percent is quick. The other is wireless, but slow non samsung wireless charger.
I kind of figured it was a battery corruption or doa issue. But wanted a second opinion before I turned it in adapter. don't want to get dinged for it.
A nicer responce at first would have been nice tho. Thank you to Syntex for your responses. They are turly appricated.

Defective / exhausted = End of Life
Both mean the same thing, OP needs a new battery, fairly obvious

Probably you don't catcg the problem. He could have a free battery from Samsung If it'll be defective.

Makes no difference where he gets a new battery from, the fact of the matter is the battery is EOL, Dead, get over it

the phone use to last untill like 8 hours while tlking on the phone
now it wont even last for an hour
Also you can buy a new battery, they are cheap this days

try conditioning your battery, you do this by running your phone down til' it turns off. Then, charge (while off) for about 7 hrs.

lol both correct, but try what wiredvs says first. When under heavy use, the battery gauge does not display the crrect charge sometimes. You will charge it until the green light shows (normally full yes?) and take it off charge, but the phone will not be fully charged.
Charging it for at least double the time with device off should rectify the issue, its a common "quirk" of winmo devices under heavy usage.
If it doesnt work then ur battery is fried so time to get a new one

Wait, what? You can talk on these things? OMG YOU'RE RIGHT!? I've never done that.
Seriously, I suspect your battery is dead, so I'm agreeing with, well, every other post in this thread. My battery has gotten weird too.. I tracked a bunch of battery usage on my phone back when it was new, now when I do the same thing the readings seem to be higher than they were because I'm basing it on percentage of battery used. I've found actually monitoring the battery usage tends to use more battery so I wanted to avoid that.
Also I've noticed mine charges up to about 88% then suddenly thinks it's 100% full. It's about time for a new one.

Just had a thought about battery life

Ok. I was responding to a thread about my phone and no reboot's. I notice that some else posted they charge there phone with it off. When i first got my phone I charged it with it off the very first time. Has anyone else done this and not had problems or done this and it still bad battery life? I have had mine unplugged since about 5:30 am and at 7:08 at 38 percent in the staus menu.

ive done the full dead to full charge (plus one hour of charge time)
i get 14 hours of use usually and thats heavy use
people need to realize this is a DUAL core phone its gonna eat battery (especially with stock drivers/software)
dont like it go back to your razor......

Hey sorry for the confusion but it was not a helpful tip. I was just stating my specific way i charged my device, but your right it is a dual core phone. I hear the thunderbolt has pretty bad battery life LOL

Unfortunately, as far as I know dual core is supposed to mean better battery management.
So there's that.

I agree, especially after reading Chris Soyars' post about the battery driver. Not only does that mean our reading of the battery is directly affected, but it also leads us to believe that other drivers on the G2X could be poorly coded as well.
The battery life is ridiculous
Honestly I"m coming from a Sony Erisson w810i dumb phone due to lost of my Samsung Eternity 6 months ago. And I have to admit that it was worth waiting for this phone back when they announced at CTIA. I was so close to jumping onto the mt4g, but this unbelievable phone totally held me back. After waiting and suffering for 4 months from my dumb phone I finally got my hand not only on my first android phone, but also a dual core phone. Man this phone is blazing fast without any lag, going from apps to apps. Once I got it out of the box, I noticed the battery life was around 30%. After playing with it for about 30 minutes, it completely die out. I charged it while I was doing the factory reset. After the reset, I turned off my phone and left it charged 8 hrs while it's off with the battery charging screen. Waking up at 9:00am, it was 100% completely fully charged. Left the house to school and at 12:30p.m, it was down to 5%. It's been only 3 hours and 30 minutes! Before the battery started to drain I had wifi, syn emil, bluetooth and even brightness on low. Also, I had GSM/WCDMA on Auto, so that wasn't the cause either. My second attempt charging cycle to full battery, well see how it goes. If the battery doesn't last me over 6 hrs, I'm definitely going to return it for another new one. I'm having a bad impression on my first smartphone and I will do anything I can to get it the way it should be. It just unacceptable and ridiculous. Oh by the way, my phone is not yet rooted or done anything with it beside downloaded few apps and games. ^__^
i had this issue last night when I plugged in my phone it showed charging and 38%. woke up this morning 8 hours later and it still showed charging and 38%, I'm thinking what the f, this never happened with my nexus one. so I plugged the phone into another outlet and used a different charger and left it for an hour and it still showed the same thing. It wasn't until I restarted the phone that it showed 100%, but I find that odd. don't have the slightest clue why this happened.

I took my friend to a T-Mobile corporate store to show him the G2x I bought. I bought mine through TMO Loyalty so I had to wait for it to ship.
Anyhow, there was an LG rep there trying to showcase the G2x and G-Slate and I asked him how the battery life is for the G2x. He told me 6 days on standby and about 5-6 hours of continuous talk time.
I'll check to see if he's still there and take a PTO if I need to, to be there with him and call my office and let them put me on hold and see if the phone has enough juice to make it for 5 continuous hours.
Unfortunately tmo decided to add some apps that run by themselves....after I deleted them I havnt had any apps open without me opening them.....I get about 20 hours wth a lot of use. This is the best battery life I have gotten on any android phone

I don't see how to get 20 hours out of that battery! Are you on edge? any live wallpapers? Account syncing?

New phone battery life

Hi!
I am new to the nexus 5 community and I just got my nexus 5 about 2 days ago
After fully charging it I started using it , I have heard that nexus 5 has battery issues and that's why I only want you people to help me tell how the battery life of my phone is for a brand new device by seeing the screenshots of my usage.
Here are the screenshots:
Looks normal to me. What's ingress? A game?

Not bad. I would disable Wi-Fi always scanning available (even if Wi-Fi is off), location to start. That's not bad though and is about what I get, but you might be able to get better SOT.
the nexus 5 does not have battery issues, at all. it stupid people that themselves have issues, not the phone.
Seems normal to me ,I bought mine month ago
There are no issues with battery on nexus 5. I charge mine usually once in 3 days, my record without charge is about a week.
It really depends on how you use it. Under constant 100% load I think battery can be depleted under 5 hours, as in every other device.
i can use my phone very heavily, and deplete my battery in 6-8 hours. but ill still get 5+ hours screen on time.

Have you tried running the phone down till it switches off? I know it's not good practice to do that often but I like to do it with a new phone relatively early as it makes sure it's calibrated - sometimes phones can either switch off at 5% or, conversely, run on 1% for hours...

You don't ever need to do that as it calibrates every time you charge the phone. Also he just got the phone and isn't having any battery issues.

He means to break in a LIon battery the first three times you kill the battery and then don't take it below 20% after that.

That's not helpful and does more harm than good. Li-Po never needs to be user calibrated in any way.

Thanks a lot guys for taking your time and helping me , nexus 5 is truly an amazing phone.
@Ben36 yes , ingress is a game and its a location based so it keeps running in the background and uses location services.
Guys , I have some questions relating to the vibration motor , is it fine if I ask here or am I supposed to make a new thread?

I was just about to start a thread about something then I read this. So here's the deal. I agree that it's almost always user error and/or over expectation when it comes to battery. Stupid people are here to stay. I'm neither stupid nor expecting too much from my battery.
I've always been intrigued by how some experienced users get great battery and some get not so great. Has to be user error I always thought. I thought this because I was one of the experienced users getting great battery life. I mean GREAT. Way over 7 SOT all the time.
So a few weeks ago my first phone had an audio port issue that I had RMA'd. I received the new phone and set it up. It had crap battery. I'm talking less then 2 hours SOT. Same ROM, same kernel, same apps, same coverage for mobile and data, same usage. I set about looking for wakelocks and they all where the same as the first phone. Nothing was wrong on my end. I spent over a week troubleshooting. CPU frequencies and time in state where normal. Temps where normal. CPU benching was the same. Awake vs screen on was almost identical. The phone is sleeping like a baby when not in use.
So, using Occam"s razor, it would lead me to believe that not all batteries in the N5 are created equal. After getting off the phone with a google support supervisor a few hours ago he agreed. Another RMA process has been set up and I was promised this phone would make it's way back to LG so they can actually analyze the battery.
Like I said, I used to think the same way you do. Now I'm not so sure.

oh, no, I 100% agree with you. just like our devices, that all aren't equal, that are all assembled in differing places, that all have smaller parts that are made in more different factories.. the batteries themselves will differ as well. it'll even probably fall onto a bell curve, where most are near the center, and less with better or worse. but 100% they vary.

Well I feel that there are always some exceptions , some phones may have a manufacturing defect and maybe the phone you are talking about did have one , but these manufacturing defects are mostly really rare.

I was just explaining what he said. The rumor is (supposedly backed up) that you kill the battery 3 times in a row but never take it close to dying after that and you get the best battery life possible because the battery works best if you only charge it between 20 and 80%. I think there may be something to it because new phones only last like half a day on the first charge but after a week last a day or longer for me. I won't derail this thread though as that's a debate that always loves to go on and I've never found hard proof either way but people who just write websites who supposedly sound smart and can word it quite eloquently.
That being said, I didn't necessarily agree with it, but I was clarifying what was said.

Thanks for clarifying. Keeping the battery between 20% and 80% is said to help with battery degradation, which after a year or two might affect how much one could get out of a full charge. Most won't find it practical to limit them self to only 60% of their total available battery pool though.
Even hitting 0% isn't as big of a problem as some may think as there is a reserve charge for protection. For instance, mine has full died on me twice due to a power outage (I even attempted a boot up) and I always full charge with no noticeable degradation after 8 months.

Estimated battery life

Hi there,
I find the battery life estimation present in the battery menu, quite weird. Indeed when I first got my phone (used), I installed it from scratch and each time I unplugged it from the charger, it always
showed be 45h+ estimated battery life and 200+ in Ultra mode.
Now, it barely indicates 25h, even if I often hit 2 days+ with 5H SOT (even if for the last day I only got 1,5 day with 4 SOT).
Did you notice the same behavior ?
The longer you use your phone the more accurate it gets

Thanks for your answer. I figured that out, but in my view it does not really reflect reality. Since it always displayed 25 hours and it can sustain up to 2 days.

Battery life issue?

My pixel has been having inconsistent battery life at 100% after charging it will sometimes say 19 hours left then sometimes at 100% it will say 9 hours. Is anyone else having this is with the pixel? Is there something I can do to help my battery life I did a factory reset after the Oreo update and have most features turned off. I've had the phone for about a week now with the 100% battery life being drastically different with each charge. I don't have FB mostly still stock apps aside from a game I play. Thanks in advance for any help.
@subvapor It all depends on how you use your phone. This sounds normal and not an issue to me. The estimated battery life it gives you is just that; an estimate. Try this: charge to 100% and use your phone normally until it gets down to around 10% or so. Then check your screen on time in battery settings. I would say 4 to 6 hours is pretty average when it comes to the pixels.

Thanks for the help I get around 3 and a half hours to 6 hours of screen on time. So I guess I'm getting good battery life out of it. I'm just trying to make sure everything is good on it as I got it as refurbished on Amazon with a 90 day warranty. Loving the phone so far though!

Yep that sounds about right. If you take it off the charger and then immediately start using a battery draining app that will really screw up the estimation too.
