    here's something really weird
    so, i have a Samsung Galaxy J5 from 2016 and when i switched to custom ROMs (doesn't matter which) the phone started to use less battery and stay on for longer, and also it started to charge from 15% to 60-70% in half an hour (which really is something for a 3 year old phone with no fast charge)

    First of all my issue is not a battery issue but at that issue. Second of all I'm and Apple user not a Android user. With saying that every time u upgrade my phone my data uses increases. The last time I went from an iPhone 7 plus to a 10xs max and in one month without any change in the way I used my phone I increased by 23 gigs. Verizon and Apple both blamed me and they way I used the phone. However the only factor that changed was the device that was being used. At least they manufacturer pretended to care for you, however for everyday people like me I just have to accept that the companies say and fork out more money just to use a device the say way I have always used for years.

    FINALLY a reviewer who acknowledges this. I could not take my S7s godawful battery life after a year, it was absolutely horrific. The phone was also slow before downloading PDP (rip that app) , and it was just absolutely pathetic for such an expensive phone. I think Samsung finally addressed this in oneUI, but as your test shows, well have to wait to see how bad battery deterioration is.

    Switch to Emergency Mode. You'll notice that the phone turns off Biometrics. The fingerprint sensor checking massively drains the battery.
    Also you can connect your device to a mac and run Terminal command "adb shell top -m 10" and you can see what is hogging all the cpu and memory. It's when I noticed the Bixby button remapper I was using was a terrible cpu hog.

    I would delete and disable almost all apps and see if that helps. Then just basically install a couple apps at a time and see if the battery drain persists. But it might just be a faulty battery. Should change it out and see if that solves the issue. I just bought a xperia xa2 and first thing I did was delete and disable a lot of apps that I don't use. Now that battery on this thing lasts a long time especially on standby and that's even without turning on battery stamina mode. Also some of the features on the phone make sure you turn them off as well. That's what I would do or just replace the battery. To bad smartphones now a days don't have external batteries which...... is an awesome feature to have.

    I've been using my S7 Edge for along time. And find out that my phone actually consume a lot of battery usage because I use often for gaming and also the phone doesn't seems to slow down. Plus the Geekbench shows that my phone scores above average than before or even from usual. Now I kinda know why it drain a lot of battery. It is because it keeps the performance smooth as possible. If I put power saving mode but on turn on speed limiter and background network usage but leaves all other setting off such as always on display, screen brightness and screen resolution. It doesn't seems to consume a lot of battery. Plus if I use normally without power saving mode, but use it to watch videos nonstop, it can last for like 3 hours. Which is normal for this old phone. If I turn on power saving mode, it may last a bit longer.

    Every single person I know who has ever had a Scheissung always has the same problem: it''s good when it's new, but after a few months it's sluggish and the battery life is really an unfunny joke. Somehow it applies to everyone I know IRL somehow people on the internet always seem to claim the opposite. And it's not normies vs powerusers, it's irrelevant what kind of people I spoke to IRL or online. Which is the main reason why I always avoid Scheissungs like fire. I never buy them and I always very strongly recommend against them to whoever asks me about my opinion. Lately I was considering reconsidering my opinions, as on the tests online new models didn't seem to have these issues at least in the high end models... but now seeing your video I'm like, nope, still the same after all. Nope nope nope

    It's hot out of pocket, therefore it's wake locks. Android has really shitty diagnostic tools for this. Best you can get is to confirm that it's wake locks, but most of the time it'll just be wake locks by "system", meaning you are no better off knowing where the fault lies. It can be difficult to reproduce this problem on demand, which is why the other phone was fine.

    The issue is that it is constantly searching for a cell and / or wifi network. I had the same issue with my Galaxy so I have to set it to switch to wifi when I am in the house (as I have little cell service at home) and make sure I switch off wifi and Bluetooth when I am out of the house to stop it searching for networks it won't find.
    Battery life is only an average at current usage levels. Searching for networks it can't find uses tons more power. If you drive through a bad cell service area, it can shoot down from 30% to 2%.
    Also, turn down screen brightness. The stupid button placement on these phones means that the screen is constantly being turned on and off in your pocket where there is no ventilation (which is why it get hot).

    My biggest gripe with Samsung phones is that their batteries drain so much while you're on LTE even when you don't use it but when you change it to regular 4G Antennas they don't use nearly as much.
    Last night I went to sleep with 95% and woke up with 95% but I had LTE Data off and no Wifi connection on either and optimized it with it's own maintenance feature under device maintenance seems to make the battery not drain as much that way.

    BigBadBoogie 24 days ago

    Solution is simple, buy a pure google experience android one device Like Nokia or Pixel :-) No bloat, just your own shit is installed hence you have full control.
    My s9+ also goes down in usage time from when new (after 6months now) but only gets hot when installing ROM updates andd getting hot is a GOOD THING as that means heat is transferred AWAY from the CPU durimg high load (opposed to some reviewers that complain about the phone feels warm in my hand...would you rather cook/boil the cpu or battery?).
    Installed apps, background data and processes and partially battery wear are likely the reason.
    My iPhone 6 and iPhone7+ were worse though. As battery reaches around 50% iPhone 6 simply died instant. 7+ was great at standby (in a drawer, with allmost zero apps installed since its a job phone) but when using it drained quickly. If out in the cold even worse. Apple still suffers from the "cold bug"

    The batterys of Samsung Phones are always crapy even the Note 2 back in its days was a perfectly legit portable heating system. I even had to change the battery of my Note Edge because of the same issue and was even worse since it even got the percentages wrong most of the time. Going from 100% to 25% in two minutes of medium use is just wrong.

  • Austin Mohr

    I had a similar problem with my Google Pixel 1. Towards the end of my 2 year contract, about 4 months, my battery degraded to the point that around 2 hours of no use my phone would die. The battery sensor was also broken as I could restart my phone and it would say something like 4% when in reality with just restarting it another time would come up at like 70%. The overall battery issues on Android could be caused by the open nature of Android.

    I've owned a Galaxy S7 for about 2 years now, and shortly after I got it, I occasionally noticed that it was running very hot in my pocket. I could clear this up by rebooting the phone, but it seemed like a fairly messy way to deal with it. To get a handle on what was wrong, I turned to an app called SystemPanel, which allowed me to see the usage of each PUBLICLY ACCESSIBLE processes, as well each core of the CPU in graphic format.

    My S7 is the Canadian edition with the octa-core Exynos SOC with 4 low-power cores and 4 high-power cores. When the phone was running hot for no reason, I discovered that one of the high-power cores was pushed to 100% at full clock speed. If left running like this with the screen on, the phone would get so hot I couldn't really touch the back of it. Not surprisingly, battery consumption was conspicuous.

    According to SystemPanel, none of the processes it was able to show me were responsible for the high CPU usage. The culprit was likely a protected O/S process, which after Android 6.0 could not be examined by apps such as SystemPanel, and so I had no way to know which one it was.

    After a bit of experimentation, I found that this undesirable state occurred most often when my phone automatically switched away from WiFi after I left the house. Because it seemed to be related to connectivity, I discovered that putting the phone into Airplane Mode for a second or two would stop the runaway process. I also determined that turning off WiFi before I left the house would ensure the condition wouldn't return.

    I'd always thought this was my fault, because I'd rooted the phone and I used a custom kernel in order to set SELinux mode to permissive (so that I could run Viper4Android). Based on what you presented in this video, it might be an issue with the Samsung fork of Android.

    This isn't to say that this very problem is the one you are seeing. Try manually shutting down WiFi before you move out of range of WiFi to see if that mysteriously clears up the hot-phone issue for you. If the phone does start to run hot, try Airplane Mode for a second or two. Also, get an app like SystemPanel to see if the heat issue is a core running at max constantly.

  • Deyvson Moutinho Caliman

    My ex Xiaome Redmi Note 4 would go for 4 days and still have 40% in battery. My Galaxy S9+ has that at the end of one day. But I don't use that much, more for work. If they didn't have different sizes for SIM chips and those drawers for chips weren't so annoying, I would probably go to work with my Xiaome and use the Galaxy on weekends when I needed pictures. People don't give much attention to battery, but it can be a big issue if your phone is more of your working horse than you multimedia center. Although I have to say that I love pictures and for this alone the Galaxy was worth it more than anything else.

I wait half an hour then turn it on and I have 38 percent. Was a real issue the other day when i tried to get a uber after a movie. Had to wait half an hour before i could use it. Anyone else get this issue? Oh it is a s5 that i have but i figured that the phone is just getting too old.
