Dear XDA Members,
I'm having some issues with the battery of my Samsung Galaxy S4 Mini. About 2 weeks ago, 2 phones in this house, a Samsung Galaxy S4 Mini and Huawei Ascend P7, started (quite simultaneously) to have battery issues. They both are on the stock rom and are not rooted. To sketch the degree of the issue: the Huawei had about 40% after 7 hours standby with 3 minutes screen on time. The Samsung lost 65% in one night just being idle.
At first we thought it were the phones that were having the issues, so we returned the Huawei to the shop (about 40 kilometers away). The people of the shop called yesterday, saying that the phone is lying in the shop for over 3 days now, still having 40% percent of battery. This made us think it was something with the antennas here in the neighbourhood.
In the mean time we had already bought a new battery for the Samsung (an original Samsung battery), and I have performed a factory reset. The battery still drains quite heavily when airplane mode isn't enabled. However, last night the Samsung still lost over 15% with airplane mode enable and all recent apps killed.
I completely lost track about what the issue can be. To me it seems that the fact that the phones started having issues at the same time is caused by an external factor. But in that case, I cannot explain the 15% overnight battery drain on the S4 Mini on airplane mode with a new battery. Should I return the Galaxy S4 Mini to Samsung to have it looked at and fixed, or should I try some other things first?
If anyone wants some more information about the issue or the devices, I'll happily provide it.
Thanks in advance!
Note: It is not my intention to root the S4 Mini or push settings to the limit to have 0% battery drain, I just want 1 or 2 days of battery life again, depending on the usage.
Edit: There are also a OnePlus One and Galaxy Gio being used in our house, who do not seem to have severe issues. This confuses me even more about the external factors (antenna failure?) that might be draining the battery. We all have the same provider...
There are many ways to save your battery life:_
some of them are as follows:---
***Go to recovery and clear cache this will help improve the battery.. Use clean master from play store, which will disable / stop unwanted apps, clear app cache.
***Try using Greenify
***I recommend GSAM battery monitor app from play store. It's very easy to understand and is very good at locating battery issues.

In settings>battery check your mobile network signal of last night and see if there is any app that is sucking your battery.
You should try greenify but you need root access.
Thanks for your answers. If the problems do not get solved I will indeed try some of those apps (I've used Greenify earlier, I know it's great )
I've monitored the apps draining the battery, and in fact there aren't many apps that use a lot of battery. It's mostly the screen or mobile radio active, which makes me think it's something antenna related.
I've spoken to my neighbour who is a customer of the same provider, and he indicated he has issues to since a few weeks. I mailed to my provider and see how things turn out
Thanks for your tips!

Yeah i also think the problem is in network quality, you should try another sim for some time and see the difference.

Hello everyone!
I own a LG G3 D855 and from the moment I bought it, I've noticed problems regarding battery life. After some resets, the store changed my battery. Despite this, it remained more or less the same. I usually never pass 3 hours of screen-on-time (no gaming!) with a full charge. After that, I considered it was due to the 2K display and reports around the internet talk about 4 hours with this phone, so I became thinking it was quite normal to have this battery life (asking your opinion, guys). Notice I usually have wifi on; 3g, nfc and gps turned off.
However there's a second problem. Sometimes, at random days, like it happen today, I get android system using more battery than the screen (around 50-60%).
I'm avoiding sending it over to the warranty, because I'll be 30 days without the phone and not sure they're figure out the problem.
Any help?
PS: I'm running stock Lollipop, haven't rooted yet. Same behaviour when I had 4.4

Battery life ... oh there are many different fators that influence the battery life.
For example: The battery (capacity and health), the firmware (many the kernel), the apps, the usage, the system/apps settings, the temperature, the (wifi and/or mobile) signal strength, etc.
So it's hard to say if your battery life is "normal" or not.
For detailed discussion about the battery life on your device, please post in the G3 General > Battery Life Discussion thread.
If you think your battery is fine and suspect an app draining your battery, I recommend to install and use Better Battery Stats (BBS) app.
For some stats you will need to root your phone though. But you can record all stats and post a dumpfile from the app to the app thread, and the "experts" will analyze it for you ... helping to identify the culprit.
Thread closed. Thank you!
Hi guys. I just created an account to these forums. I've used them before when rooting a previous phone. I have a problem with my new S6. I got it about three weeks ago, and I love it. The only problem I have is the incredibly short battery life. There has to be a problem with my phone, because I'll have a battery life of about 5 hours on a good day, but usually 2 or 3. The phone will get mildly hot, and all battery will drain rapidly. I will regularly lose ~40-50% in an hour after it starts heating up. I've been simply dealing with it for a while, after a failed attempt to find a solution on Google. I regularly close my apps, and I even have powersaver on at all times now. Last night, I closed all apps, then restarted my phone. It was at 98 when I fell asleep. I woke up 9 hours later and it was dead. I have checked the battery info a couple times, but I don't ever see anything rapidly draining battery. Could this be a hardware problem?
I have a Verizon S6 regular. Model number SM-G920V
Try to calibrate your battery first.
I suggest reinstalling the software using Samsung's smart manager and updating to 5.1.1, I never had your issues but noticed a big improvement with battery life. I'm sure you have a rogue app somewhere running havoc. There's also a lot of things you can do to improve battery life after reset, like disabling background data on certain apps that you need need constantly connecting and using data like Facebook when it's not even in use. Just play around with your phone to know the ins and outs

Thanks for the suggestion. Where is the Smart Manager? I Googled it, and found a thread saying
It is included on the phone, however there is no way to access it that I've found. You can find it under Application Manager - ALL. Scroll down to Smart Manager and select it, you will find that the app is running but we are cannot access it and the DISABLE button is grayed out. My guess is that Verizon wants us to use their My Verizon Mobile app instead of Smart Manager. I heard that AT&T did the same thing.

I suggest wiping the cache. I was experiencing a similar issue. After wiping the cache, consumption return to normal.

98% gone during 9 hours of sleeping? wow...
1) Do the factory reset, full wipe and see if its gonna get any better.
2) If still the same problem, then download latest firmware for your model from sammobile.com http://www.sammobile.com/firmwares/database/SM-G920V/ and flash it via Odin / Download mode
If still the same issue, then contact samsung for the warranty :X

You might try a Sprint fix since your Verizon S6 has CDMA too. Since you've got a Verizon phone, this setting may be somewhat different. On my Sprint S6, I changed the setting under 'Mobile Network', then 'Network Mode' to LTE/CDMA' instead of 'Automatic'. That made my battery life much better. I think I remember a friend with a Verizon S6 and it had 'Global' instead of 'Automatic'. So change it out of 'Global' mode and see what happens.
Before anyone asks I have searched, Googled, looked on reddit, and gone through these guides on xda:

I have a Galaxy S6 fro Rogers in Canada (no root) and I recently updated from 5.0.2 to 5.1.1 and my battery life has gone to crap, my usage patterns and apps remain the same as before. Previously I would get about 4 hours SoT, 5 on a good day. Now I can barely get 2.5 hours SoT. I have no other problems with this phone, none of the RAM issues, lagging, or over heating other people have mentioned, my only problem is the poor battery life.
The apps are primarily use are Facebook, Puzzle and Dragons, Messenger, and Chrome, I realise that these are battery guzzlers but 2.5 hours is ridiculous and I used to get more using the same apps. I typically start using my phone around 8am from 100%, and by 5pm after 2.5 hours SoT it is around 20% battery life, previously it would hit 20% around 11pm with about 4 hours SoT. No apps are draining a particularly large amount according to GSAM.
To reiterate the things I have done to improve my battery life are:
1. disabling unused apps in application manager
2. setting brightness to lowest setting on auto
3. restarting phone
4. restarting phone in safemode
5. clearing cache
6. performing a factory reset after updating to 5.1.1
7. leaving wifi gps off when not in use (but I'm not constantly turning it on and off either)
8. Greenifying apps I use less than once a day (but anything with push notifications is not Greenified)
Additionally I have not moved or anything and reception in my area has always been decent. Any suggestions for what else I should do? My phone is still under warranty, should I send it to a service centre? Or should I try rooting it an actually deleting bloatware and having an ad blocker (though this would void the warranty...).
Please advise! I am very frustrated with this battery life.
Im having the same issue after updating the GS6 on Wind (Canada) to 5.1.1. Terrible battery life and Android OS draining battery as well. I barely get 2.5 SoT.
I'll join this unfortunate crew. I have to charge everyday before leaving work in order to get through the day.
Take off the charger at home when I leave and by the time I get to work(30-40 min drive) I'm at ~95%. By lunch I'm down to around 50%.
Hoping Android M fixes some issues
Clear cache in storage option and reboot! It will very slightly improve!

http://communityforums.rogers.com/t5/forums/forumtopicpage/board-id/Android/thread-id/31962/page/32 Read through the last 6 or 8 pages over there. A lot of unhappy people with Rogers right now using the S6. I'm in the same boat. Crappy cell service, times it will show bars of 4G but then tell me there is no network connection. Try to make a call with full bars at 4G and it will say not registered on network. Text messages being sent and received twice automatically. No connection at all in places my HTC used to have 4G if not LTE. I had to send my S6 away for camera repair for a week so I pulled back out my old HTC M8 for that time and my connection was stable and awesome everywhere just like I thought it should be. Now that I'm back on my S6 it's barely hanging onto EDGE in places I had full 4G bars on the HTC like at my desk at work. Places I spend a lot of time at.
I suggest you call Rogers and talk to the tech support. Tell them your issues. The more complaints the faster the issue will be resolved. It sounds wide spread so don't waste your time trying to fix it yourself.

Thanks for the link, I didn't think to check the Rogers forums, I'll call their tech support to let them know of my issues and hope they are working on something.
I also have this issue. I was able to make it through an 8hr work day before the update. Now it's down to 10% or to completely dead. My usage at work did not change. Sucks that I have to plug my phone into my car just to get enough juice to make the drive home.
Just to confirm are you guys all now on 5.1.1 and is battery life the only issue you are experiencing?
I talked to a rep with my carrier (Rogers) and he said that the known issues were to do with connectivity (calls, data), but not with battery. He said battery issues that could not be resolved by a reset should sent in for service.

There was some discussion in various places about cell standby being a HUGE drain on the battery when connected to WIFI.
My issues are data and call related. I've never been one to care that much about battery but it does seem off from what I'm used too and I'm seeing some long times on the mobile radio being active.
I think it's safe to say that all of this stems for the 5.1.1 update. Cell reception "problems" can lead to big battery drains and if our phones are having issues staying in tune with the towers, it could cause big battery drain.
Keep an eye on what might be causing your battery drain though. It might be something silly like an app trying to do something.
I have also noticed a sharp drop in battery life now that I'm on 5.1.1.
USA AT&T.
I'm really at a loss. GSAM says "Android System" under apps as well as "Phone Radio" are the highest drain.
Has anyone noticed their battery getting incredibly worse over time? I bought my S7 on release (non edge). And since then, I've noticed that it doesn't last no where near as long. Today, for example I started my day at 7:00am when the battery was 100%. As of 30 minutes ago, the battery reached critically low (5%). From 7am all I did was watch a few videos, facebook, snapchat and then play music. But all the above for not too long.
I've also noticed that once the phone hits the 15% battery (I know due to the notification), that within minutes the battery can be done to 10% or so, without touching it.
I'm more so tempted just to take it back, unless there's an easy fix OR it's a known issue with the current version.
Thanks!

I've definitely noticed this since rooting. Maybe it has something to do with that? Like a ROM you flashed or what not? I'd like some suggestions here as well.

I haven't rooted the S7, it was the first phone that I've left stock from opening.
What does the battery stats say is using the most mAh?
Facebook app is a known battery hog
Obviously over time, you'll install different things, and slowly the phone will start using more and more power running background apps
A backup and Factory reset will show if there is a hardware / battery issue, or if it's purely from stuff you've installed over time
Also clearing the caches from recovery could help
yeah ive noticed this too. My usage habits havent changed but my battery life is almost half of what it was when i just got the phone.

Cache has been cleared from recovery, and I don't generally install many apps so since I've bought the phone the apps have stayed the same.
Android system is always on top. Unless of course I spend hours on Facebook.
Might have to factory reset. I've used my phone with the same apps and time since I've bought it, and I'm finding I'm charging it 3x as much.
I think it's a root issue - deep sleep.
After S6 Edge Plus, when you root a samsung phone, it won't go in deep sleep. I believe there's a fix for that.
Have you checked the battery usage stats? It gives you the breakdown on what apps are eating up the battery.
I have had my S7 for about a month and battery is about the same.
Just to update this thread for those that may have a similar issue...the other day I couldn't live with the battery life the way it was. The phone used 50% in several hours where I barely used it.
Decided to completely re-flash with stock (was stock before) as opposed to simply wiping all data. A week in, and the phone's battery life is back to the way it was. I went to bed when it was on 100% (as a test) and woke up 7 hours later with the phone on 94%, with wifi, location and bluetooth on.
Not sure what had caused it to use so much battery previously, but it's back to what it should be and that's all that matters.
hi with my s7 exynos i do 3h screen. i think there is a problem. i bought my s7 one week ago. can anyone help me?
Rooting and installing custom kernels when done right should greatly increase the battery life of your device. This is a well known guide here on XDA for improving battery life for our devices.
That being said, Lithium Ion Batteries hold less charge the more cycles they are put through, its a given fact but as you said your device is relatively new and therefore should not be experiencing this kind of problem. The way I see this is there are 3 possibilities which may be causing the said problem...
1) You have rooted the device and done some modification/s. ( which you haven't done )
2) Your battery is being drained by a service ( Like Oculus or VR ) in fact a number of reddit users complained their S7 was overheating and battery was draining really fast for some reason. Check This page out, It might help you.
3) Battery Defect, you must've gotten a "bad" model, if you haven't tripped KNOX you could try bringing your phone to Samsung and see if they would fix or replace it.
Good luck
I think this has to due to them samsung updates. As far as i know samsung been always doing things like this where they made the OS slow as hell after a while so you gonna get a upgrade sooner but a battery should last 2 years minimal without degrading.

i get like 5 hours screen on time and bout 1 day standby time but i have most bloatware disabled with the package disabler. But if i was you i would contact samsung.
This happens with Samsung updates on every Galaxy phone. It's like a curse. It's unavoidable.

May i ask if the people with these problems use the fast charge? I hearing many bad things bout this so i switched it off and must say the normal charge isn't that slow and if it can keep the battery good for longer then we all should use this.
I turned fast charge off about a week after I got the phone, was making the phone and charger pretty hot for the sake of about 5-10 mins quicker charge
Pointless really, unless you are desperate, only have a few mins spare and need as much power as possible in that short time, and if that's the case, enable it for that one time
Restrict background data on all but the most important apps (phone, text, email), dave power all but the most important apps. Battery life is fine

I've bought the international version of the S7 (the only one available here in Portugal) which is the SM-930F on the last tuestday (2016-09-16).
During the wednesday, I've noticed that the battery drained really fast, but I thought that it was because of the whole first-day configuration / installing 50 apps thing.
On thursday (yesterday), I removed it from the charger at 8h30, barely used it, and at around 13h00 it had 44% battery. I don't have a lot of background syncing or anything like that, just the normal I've used on other phones before the S7.
I've read somewhere from people that had similar problems and they said a factory reset solved. I did a factory reset but the battery kept draining at the same rate.
So, at around 20h30 I went to the store and asked for a replacement. Exactly the same model and color.
I went home, installed all apps and updated everything so I could test it today without updates and downloads. I didn't restore any settings from previous installations.
Today I took it off from the charger again at around 9h00, it's 14h30 and it has 64% and I barely touched it! I've checked some stuff at lunch time for like 10min, that's all.
What can possibly be wrong here? Everyone on the internet says that this phone's battery life is one of the best out there, but it's draining faster than any of my previous phones!
Both the original and replacement phones were sealed in the box.
Any ideas?

I've bought the international version of the S7 (the only one available here in Portugal) which is the SM-930F on the last tuestday (2016-09-16).
During the wednesday, I've noticed that the battery drained really fast, but I thought that it was because of the whole first-day configuration / installing 50 apps thing.
On thursday (yesterday), I removed it from the charger at 8h30, barely used it, and at around 13h00 it had 44% battery. I don't have a lot of background syncing or anything like that, just the normal I've used on other phones before the S7.
I've read somewhere from people that had similar problems and they said a factory reset solved. I did a factory reset but the battery kept draining at the same rate.
So, at around 20h30 I went to the store and asked for a replacement. Exactly the same model and color.

Hi
Most of times battery consumption is due to settings , WIFI , e-mail sync , location , rogue app , facebook..... review them......maybe do a factory reset , install nothing and see how it behaves , install app in smaller lots to see if there an increase on battery drainage , if you where root there is an app that is great to see exactly who is the culprit

If it was a rogue app, wouldn't that show up in battery usage?
For apps, syncing, location and network, I have the exact same settings I had in my previous Note 4 and LG G2, and nothing like this ever happened.
Location is on all the time, I'm connected to my company's WiFi, 4G always on (overriden by the WiFi most of the time).
The only thing I didn't have in those phones was the "screen always on" of the S7 that shows the time, which reviewers say that it's so optimized that it barely makes a difference.
I wouldn't be complaining if it were draining a bit faster than the Note 4 or the old LG G2, but it's actually draining like 4-5 times faster!
Yesterday I had both the G2 and the S7 with me, with all the same apps, with a SIM card from the same network/account.
When I reached the store, the S7 had almost critical battery, while the G2 had around 80%...
The S7 didn't get hot or anything.
I will wait a couple days to see if it improves, but it's extremely disappointing, after spending 730€ on a new phone (around $820).

Battery drainage is a Bit** , some time is hard to find out what is going on and you need to be patient and methodical
to your questions
If it was a rogue app, wouldn't that show up in battery usage?
Not necessary , may be is a process and do not show in there , most times you need a better app (BBS the link i gave you) and be root to see those process , or by discarding apps to find out
For apps, syncing, location and network, I have the exact same settings I had in my previous Note 4 and LG G2, and nothing like this ever happened.
Different phones , not necessarily the apps behave the same in different phones
Location is on all the time, I'm connected to my company's WiFi, 4G always on (overriden by the WiFi most of the time).
Try different settings and see if they make a difference , see what apps are using location , do not have wifi on all the time during sleep......
In my case i do not have even half of that drainage , of course we all use the phone in different ways and have different apps......as i said is a royal pain in the a** and need to be patient and methodical to find out if is a real hardware problem or a configuration problem
After reading this,
https://www.reddit.com/r/GalaxyS7/c..._s7_edge_battery_drains_20_overnight_8_hours/
I've decided to wait for a few days to see if it improves. The poster seemed to have the same problem I have and he said it stabilized after a few days.
If he problem persists, I will try the things you said.
Thank you.
Maybe you can install Better Battery Stats and wait for it to give you some answers.
I would suspect that the phone has trouble connecting to network, WiFi or mobile network or tries to constantly fix to gps signals. A constant search for better connection results problems like yours. If you can, try another operator sim for a day, or try another location.
Perhaps do not use wifi for a day to rule out bad compatibility with your routers settings.
My S7 SM-930F do not lose ever one percent per hour if left unused with everything on and no powersaving.
Did you use Memory card ? I had similar issue on S4. There was damaged file and phone tried read it whole time.
I had the similar problem which was caused by Email App. Try to install Wakelock Detector Lite and see which app drains the battery most. In my case, Email app was preventing phone to enter deep sleep mode and it can not be seen in Android battery statistics.
Wakelock Detector does not need root but you need to enable developer mode and use adb shell. Code is below, you can Google it for how to.
Code:
"adb -d shell pm grant com.uzumapps.wakelockdetector.noroot android.permission.BATTERY_STATS"
Here's an update:
So I've waited a couple days and the battery seems perfect now. I've unplugged it yesterday at around 12h30, used 9gag, browser, facebook, youtube, gmail (a bit of everything, actually) and now it's almost 10h00 and it still has 44%.
I've installed that GSam app and it seems that the phone was transferring lots of stuff through WiFi in the first 2 days, I assume that was the cause.
Thanks everyone for the tips!

Thank you for reporting back on how this went for you! Not everyone is so good at doing us this favour!
A lot is going on with a newly initiated mobile and perhaps it was a new firmware too that was downloading in the first days and together with everything else the battery life seems terrible to start with. My S7 downloaded a new firmware and flashed it in my first few hours with the phone and I didn’t notice before it wanted to reboot to flash. Together with all other updating going on if you reinstall apps and set things up it takes a while for the poor thing to settle!
The switching of phones did of course make the whole process start from scratch again and this made the problem seem even worse to you!
Well, Samsung should put some kind of warning in the box or something, I was getting extremely disappointed. I'm very happy now though, the phone seems to be amazing.
