[Q] Terrible Battery in Germany

Hello all. This is my first actual help post cause I now have a problem, but I have been lurking for a while.
Anyway, I have a rooted S5 from verizon that had awesome battery life compared to my old nexus - I could hit 2 days with one charge. Anyway, I am now living in Germany, will be here for the next year, and I can get maybe half a day before I hit 30%. It feels like I am back with the nexus, I have to plan my charging around what I will be doing.
My carrier here is Lebara. Under the battery stats Android system and Androud OS dominate usage. I had that under control in the States with some TB tweaking, but it is back with a vengance. I haven't updated the OS and am not planning to until L comes out and is compatible with root.
I am never far from an outlet, but I don't want to return to my old habits of always plugging in.
I just had a thought - is it possible that the different electricity standards here nuked my battery? If this is the case, should I worry about my tablet too?

I am also starting to notice a lot more lag and even freezing from normal usage.

S5 frezzing and low batery life.
same here . in the states running stock os flashed to PP

Note 4 Problems!

I have a galaxy note 4 on sprint. When I first got the phone, it ran great. I love the long battery life and multitasking abilities. However, I've noticed recently that it seems to be running slower. I'm on stock, unrooted firmware and I've only had the phone about six months. When I first got the phone, battery life was excellent. I only seemed to lose about ten percent battery for an hour of normal use (screen on, low/moderate processor use). Now I lose about twice that. I also downloaded the AnTuTu benchmark test and ran it. When I first did this with this same phone six months ago, I achieved a score of around 50,000 but I ran the test again last night and scored 27,000. I had a friend run the test on his note 4, also about six months old, and he scored about 50,000. I also cannot connect to a Bose Soundlink Bluetooth speaker that I used to have no problems with (still with same note 4 unit) and I had to factory reset my android wear watch to get it to connect to my phone, another issue I've never had. On top of that, I can no longer get the phone to vibrate with the arrival of a text message. It will give a notification and sound, but no vibrate. These issues are frustrating, especially as the phone is only around six months old. Any help with this stuff would be greatly appreciated. Thanks!

I think the current and last few versions of Google Play Services have a battery drain bug. Google Play Services (which I'll abbreviate as GPS) is updated automatically via the Play Store, but you don't confirm the update like a normal app. So it basically updates without your knowledge.
My battery life was normal on my ATT Note 4 about 2 weeks ago, with Location always on (power saving), power saving mode on, bluetooth always on, and my Moto 360 connected. Lately though, the battery life has started dropping faster. I used to get home from work with about 75% battery left. Now I'm between 50 and 65%.
If GPS is indeed the issue, then all we can do is wait for Google to fix it in a newer version. You can uninstall the updates, or even manually install a certain version, but within about 24hrs, GPS will automatically update itself to the latest version again.

Thanks for the information! I didn't think of that. Would that cause my AnTuTu benchmark score to be low, as well? The phone just seems to lag sometimes and the benchmark score seems to be evidence that it's more than just my perception

Maybe?
You can try uninstalling (which will downgrade to a very old version) GPS updates via settings-general-applications-all-google play services
You won't be able to properly use many Google apps while downgraded though, and GPS while probably auto update over night. But while downgraded, don't open Play Store and try Antutu again to see if there is any improvement. Run your phone like normal too and see if battery life improves. If all this is better, then it's definitely GPS.

Not sure what happened, but the benchmark score is back up (around 46000). Battery life has not gotten any better, and I'm having more Bluetooth problems, specifically with my LG g watch now. This is frustrating. Anybody have any idea? Would it be within the realm of possibility to get the phone replaced under warranty? I've only had it since February. I'm also having problems with text messages actually sending. They show as sent from my phone, but people don't receive them

S7 edge same battery defect as Note 7?

I noticed that there have now been reports of the S7 and S7 edge exploding in the same way the note 7 has even giving a guy 3rd degree burns. This got me thinking about the two s7 edges I've had and the quality control issues that may be plaguing our devices as well. My first s7 edge had great battery life, 6 hrs+ SOT, and ran cool all day. I then returned it because a better promo came out within 14 days of my purchase and got a new one. The new one has never made it past 3.5 hrs of SOT and runs hot all the time. This is with the exact same apps installed, the same settings, and initially the same firmware. I've tried running 100% stock, FDR's, freezing apps, rooting, and tweaking just about everything with little to no success which makes me wonder if this is a hardware related issue with the battery. Maybe this explains how some people are getting 8 hrs of SOT while others cant make it past 3. It's a definite possibility in my mind that we have the same or similar manufacturing defect in the s7 edge as the note 7.
http://www.sammobile.com/2016/09/11/samsung-sued-over-exploding-galaxy-s7-edge/

I've never gotten anywhere near that much screen on time. Mine's more in the 3 hours range maximum. If the screen is off, my battery seems to decently, but I've never seen the crazy high numbers that many others have.

My SOT is rather high, but I only experienced battery issues after rooting the first time with the 935V kernel. After moving to 935U, I went back to VERY cool CPU & Batteries, and better SOT.

Hot S7
Try turning off all of the Amazon crap if you don't use it. They tend to use up a lot of battery time when they are running in the back ground, and by default they are installed and set to run always. That might help a little bit.

Google any device and you'll find cases of a few burning. That's just the state of LiPo technology at the moment.
The Note 7 has had upwards of 30 cases in a very short period of time, and a known quality issue from a particular manufacturing partner. What you'll find with the S7/S7E is nothing near that severe, and on par with contemporary devices like the iPhone 6/6s.

Update: I called Samsung and I'm not even kidding here's how the first part of the conversation went:
Me: Hi I have a galaxy s7 edge and I'm a little concerned because it is draining quickly and the phone runs very warm and sometimes hot.
Agent: That is not good! Are you hurt?
Me: No I'm okay
Agent: Thank god! Please power the phone down and send it to us. We will fix it or send you a replacement within 5-7 days. What is your imei number and email address?
I got an email within 5 min with a return authorization and then called verizon because I don't want to be without a phone for 5 days. I told them the story and they are sending me a replacement and I just have to send the old phone in. Either Samsung is being super cautious or they know there might be an issue with our phones as well. Either way I'm looking forward to seeing if the replacement is any better. I saw that a couple of people have reported getting referb phones that run cooler/better.

i believe theyre over 90 now lol.. i doubt theres a defect in the S7/S7E, ppl are just wary now after the N7 recall even though unless you do anything crazy theresasmaller chance of it atually exploding..
i actually take my phone off the charger for a few mins if i feel it burning up lol

My phone has been doing this. Getting super hot and the battery goes from 100% to 0 in 2-3 hours. I'm gonna call them

If I remember correctly they had a factory issue and had to outsource like 10% of the note7 batteries to a different company. They didn't do that with the s7e to my knowledge so if there is an issue it's probably not related to the note7 issue.
I had this issue earlier this week.....phone wouldn't even last a normal 9 hour shift at work and I was down to under 15% by my lunch break. Lost my mind going back to stock and reflashed stang Rom 3 times...the third time I forgot to install greenify and the problem was solved. Reinstalled greenify and my battery drained like it was a countdown clock. Went back stock, reflashed and didn't bother with greenify, just rolling with forcedoze and have 0 issues. Currently at 32% and I've been off the charger for close to 12hours and even had to use my flahsight for a solid 10minutes

My original Samsung Galaxy S7 Edge ended up literally melting all USB cables and chargers that I plugged into it. This was roughly after 4 months of owning the device, it always got really hot while charging, but one day it started smelling like burning plastic. I successfully got a warranty replacement on that device, my current S7 Edge still gets hot after charging, but nowhere near the original device.
I would venture to assume that 'fast-charging' is the culprit behind overheating, as you are pushing 2 Amps to the battery (compared to your usual 700mAh - 1 Amp standard USB charger).
As the Doctor stated -- you will always have SOME defects in a very small percentage of devices. As the S7 Edge has been out longer, I would say we are okay

Would you recommend the Galaxy S7 Edge in late 2017 ?

Hey guys im looking for a new phone that isn't harsh on the budget but still delivers (currently using Nexus 5x) and im deciding between the Galaxy S7 Edge and the HTC 10 , the S7 Edge is refurbished 300 pounds and the 10 is brand new 270 pounds . I would like to hear your opinions and is it worth buying , pretty much im looking for a better performance and battery life .

I'm using the s7 edge since 1,5 year. I had never better battery life, and the performance is still in the top of list I think. Before that I was a huge fan of hts one series.

I would definitely recommend. Even after using it for 18 months, i'm still so happy with this. I believe there are many like me.

What kind of screen on time do you get . Im getting max 3 hours screen on with a total time off charger 8 hours on the nexus , my usage is kinda heavy because i like to play games listen to music on spotify and chat , and did you encounter any issues . Also is it easy to root and tinker ?

Yes, exynos is a Samsung fabricate, so it's better more energy efficient. I think it has also a lil bit better performance.

Thanks for the information guys i think ill buy it in a few days

Budgetise, it's a good decision.
I get 5 hours+ on 3g only and 5-7 hours if using on wifi. 5 hours is the bare minimum. I'm on Superman Rom 2.8, Notorious Kernel. Nougut. On stock, it's possible to get 4-5 (or more if you use wifi mostly)hours easily. I use custom rom for features and control. My average battery life is 12-18 hours

Do you have exynos or snapdragon?
Exynos is more energy efficient.

Is seller refurbished and pre-owned by a person basically the same? Because i found a pre-owned model that comes with the headphones , cables , otg and a wall plug thats european standard (which is what i use) and 18 month warranty. The refurbished one comes with a usb cable , sim tool and a micro fiber cloth and 12 month warranty. (The price is the same) Also the pre-owned has pictures and its in excellent condition , the refurbished claims that its in excellent but no pics.

There is no reason to ask which one you should choose.
Check the imei no.-s and look is everything in fine condition. A phone in almost perfect condition can also be refurbished, and when the refurbishing was unauthorised, the warranty is already lost.

Htc software is too bad that it's neither the well known Sense nor Google's AOSP. It is just some **** in between them.

I am using Superman Rom which will give you more control on your performance and optimizations.
My device is Exynos.

Definitely, the s7 edge, for the first i am very satisfied with my purchase.performance wise its ROCKS!!!
my brother has s8+ but not even once have i felt that his phone is better than mine or anything. infact with batman rom sometimes my phone outperforms his
i am not a heavy gamer i just play clash royale on it. my phone usually gets through the day with just 1 charge.
n also also that edge screen is a beauty.makes it stand out.

Excellent phone in the exynos variant. Great performance and battery in stock - even better when modded. On Superman 2.7 and Superstock Kernel 2.9, chuck in greenify and force doze and I can easily go 3 days on moderate use (I estimate 5-8 days based on rate of battery loss, but I'm never game enough to try). No performance sacrificed in my configuration too.
I would say better then the HTC 10 in every way (although that is a very good phone too ) Buy the G935F if you are interested in Customs ROMs etc. Better battery life than the S8, S8+ Note 8 with pretty much the same features - grab the S8 launcher if you want the swipe up to open app drawer. Get an S8 port if you want all of the features of S8 (although i reckon the additional features are kinda useless haha).

I gravitated toward the S7 Edge from your comments and after watching a battery life test video in which the S7 Edge lasted 4 more hours than the 10 and in a heat test in which the htc after 20 mins of real racing 3 got to 45 degrees and the S7 Edge was like a boss on 37 degrees.

Oreo battery feedback

Hello,
I dont really found centralized information about Oreo and feedbacks regarding battery life.
So please, people from Korea and North America, can you provide some feedback about Oreo update, especially about the battery life ?
I heard some negative opinion from this video : https://www.youtube.com/watch?v=m5hH0TQY6Jg
Before he was at 5-6h SoT, after update 3-4h
Thanks !

It was entirely predictable and expected that there would be no improvement in battery life or performance with Oreo despite all the anticipation.
I have literally NEVER seen a major operating system upgrade actually speed up performance of identical apps on the same device. Sometimes there might be a non-significant decline, but never an improvement.
Each Android upgrade promises some new trick to improve battery life like wakelocks etc, but it's only theoretical and perhaps applies only to brand new hardware.
Otherwise the progressive process of bloating in updated apps and system software use more power and more resources which more than compensate for the supposed improvements in efficiency
I think the few reports that have mentioned improvement are just the random variation that people get, even with Nougat, or even day to day on the same device.
Sometimes I get 1% standby drain per hour and sometimes 3% with no change in use or settings. I have found no consistent way to control this, including trying all of the tips mentioned (except for wiping my phone and starting from scratch).
So far the video reviews that I have seen of Oreo on the G6 are pointedly unexciting and confirm my predictions. As far as I am concerned the only reason to update is for the security patches. I am hesitant to update given that going backwards is difficult on a unrooted device.

maybe some little improvements are made, sure, nothing big to say its a major update, NO!
is almost only a Android version bump and a security patch. PERIOD...
The features this new version introduced is low and people who update the phone dont will see a big change, i already see some videos of update in youtube and didnt see too much difference.
Of course is a good thing LG doing it but isnt night and day,is more like some hours of difference.
Lets see with time to time the Doze mode and power savings features step in and see some change in battery life, i trust LG make something to improve it, again nothing special but for me that already make a difference.

2 remarks :
From my experience, I never saw an android update improve battery life too. But that was a long time ago, with "cheap" phones (expect nexus 4, so disappointed). But recently, a friend bought a Nokia 8, and after the Oreo update, the battery has become so amazing, I was really really suprised and so jealous! So now I still have a little hope ...
However concerning standby drain, for me it's pretty ok. In airplane mode lost 0 or 1% for all night, and with data or wifi, it stays "normal".

You guys have something else going on.like the first post said it depends on day to day and other factors like many apps running in back ground.My phone and battery have 0 issues.on full charge it stays at 100 for about 10min on heavy internet use and then drops about 2percent per hour.I only charge my phone every 3 days.I also found phone much faster after oreo and less studder.I suppose because part of the update is to have less apps running in background.I wouldnt really listen to some users because the change log for oreo is huge.Soooooo many changes under the hood.people should read the change log before giving false facts(and they are false)Always gonna have some dude complaing about something

Did you make some improvements like disabling logs and reducing resolution ? Any reset after oreo ?

I disabled event logs yes.kept screen on large size and no resolution change.Yes I did a factory reset immediately after.I think alot of people are having issues with battery because they dont calibrate it first when new out of the box.As a rule of thumb no matter what electronics i buy i always charge to 100 percent and literally let it drain to 0 percent then full chage again.Do this step twice in a row and i can pretty much guarantee you wont have issues with battery that are out of the ordinary.LOVE MY G6

There are people that mainly use the phone under a wifi connection, and others that use it under a mobile network, this is just an example to give you an idea of why there is much difference between users

Y kllua but people are complaining regardless of wifi or mobile network. My package includes 6gb of network per month every month i spend 4gb etc...
And lots of people i see have bluetooth, nfc ( if they even thats in or what it even is. ) and then comes some1 like you and says ooo wifi on. What im gonna use at home ? Data ? To consump battery and empty my month data, and what im gonna use on streets, work, free time outside house etc. Mobile fking data. You think wifi is all around us

Well, my G6's battery sucks because at work the phone switches every couple of minutes to all the networks, and so I'm not able to reach home after 9-10 hours with 1-2 of SOT without charging a 20-30% during lunch, besides in weekends where I'm almost everyday under a wifi connection I easily reach 4-5 hours of SOT with gaming in a full day usage.
Also yes, there are many other parameters, like BT, NFC, GPS, Apps ecc...

So finally got Oreo thanks to LG Brigde.
The battery stock app seems really... broken ? Please see screenshots.
The message says : "2 days ago , 1h27min left the conversation."
PS : I made a factory reset after the oreo update.

Mine has actually improved! I'm getting like 30 minutes more (the improvement came after I drained the battery almost completely and charged it back like 3 times and after a factory reset). Not much but I can't complain. I'm actually happy for the improvements in fast charge speed, it's even faster now.

Third day with Oreo now.
Battery life is great, at least as good as before. I have 3.5h of screen on time right now and I'm at 43% battery at the end of a full work day with traveling etc.
And that's with Nova Launcher, Gesture Control [root], Always on Display and Pixel live wallpaper enabled.
Very happy with the G6 at the moment. Of course battery life always depends on your personal use and different phones provide better battery life for different people... G6 seems to work well for me and definitely better than the Huawei P9 I had before.
For people with battery life issues I suggest this: Battery life guide (I keep resolution at max because it messes with AOD and camera)
and also if you don't use google voice assistant try disabling the google app and use the chrome search widget instead. And keep location services on battery saving mode if you don't need GPS all the time.
