Bought mine preorder 3.Nov
This is my fifth day with my S7 runs like a charm except some problems regarding incoming call

When you say drain fast, what do you mean? What screen time are you getting? What's the issue with incoming calls?

I have the S7, 64GB and I also feel the battery drains quite fast. Around 3 Hours screen on time.
Currently trying with disabling the 2nd SIM & also turned the performance setting to low power and but has not made much difference yet.
Also I suspect the "Clear background App" setting/system app is unnecessarily killing apps in the background and causing even more app-restarts. Any way to turn this app off and instead use Greenify ?

I use my s7 five days and it was fine, tonight phablet did not respond to pressing the power button, left display off, I pressed multifunction button to wake up the device, but nothing happened. I attached charger but after an hour of charging phone is always off. I took away the SIM card and SD memory card and charging unit remained, and after another half-hour phone is always turned off and does not start anymore.
for five hours phone is dead but feels heat in the area of ​​the rear camera ... I think the problem started from the battery, because the same area was heated slightly during charging.

I have got the same problem, the battery is running down too fast. I only have used since last 3 days and I have to charge the battery twice every day. Any solution?

Hi,
No troubles here, battery is fine on my 3G/16G.
Do you have the problem when the phone is as new and wiped out clean from the recovery ?
Can you try this withouth installing anything ?
Best regards

For me, at the end of the day, about 40% of battery left.
I turn the battery pref into low performance, and no problem for my use

I am a light user and I get only 8 to 10 hours with the S7.
I recharged from 12% to 44% in less than 20 minutes,but it seems to empty just as fast.
I have heard that you should let it run down,till it shuts down and then recharge it and that helps the battery life

i have exactly the same problem .. no answer from elephone

I had same problem with S7 Mini, turned out it was 'Play Services'
Check this link for details. https://forum.xda-developers.com/elephone-s7/help/elephone-s7-mini-terrible-battery-drain-t3560035

Try this.. Go to settings, clear background application,, check all the apps as whitelist. It turns out the phone usually clear background applications, its logic to save battery is by shutting off every app which is running in background, but by doing this, the processor will work harder to bring up every apps back to work which means more energy more energy consumptions.
And turn of your finger print scanner. I did these and got my discharge rate 1%/h in standby.

Thanks, testing.
What about the Intelligent battery saving" toggle under battery settings.
I've left it on for now

I switch it on.
Yesterday i got 1 day and 10 hours battery with 3 hours screen on time, it was 17% just before i recharge it. Low power mode

TyTN - excessive battery drain

Hi all,
I've got a serious problem with my Hermes:
The Battery is drained very quickly and becomes very warm. According to acbPowerMeter with 3G OFF, WiFi OFF, Bluetooth OFF and no running programs its drawing somewhere between 350-400mA (!) in Standby mode . But now the strange thing: when i switch WiFi ON the current drops to about 80-130mA sometimes 40mA or less.

I already searched the forum but couldn't find any solution for this.
ROM: Pays ROM 2.15 GER
RADIO: 1.50.00.00
same thing with
ROM: HTC 3.54.257.2 GER
RADIO 1.47.00.10
Obviously you know you need to replace your battery immediately.
I'm willing to bet that you've configure your WiFi to search for a 'hidden' SSID (then you switched the power setting to 'performance', instead of the default power saver mode).
The Device and battery are brand new. (Its a replacement for another TyTN which had a defective camera and also drained the Battery very quickly).
WiFi is set to energy save mode and it isn't searching for hidden networks. The thing is when WiFi is OFF the device drains more current than with Active WiFi!
Sorry, unfortunately i can't find any useful information in there.
Sorry if this doesn't belong to this thread, but I have a similar problem:
After using WiFi and turning it off, my TyTN's battery starts getting very warm and drains very quickly. I turn it off, remove the battery for a few minutes, then put it back and power the device on, but in a few hours the battery heats up again and drains completely very soon. I have no idea what to do with this... Any advice?
No, ideas? Help would be much appreciated
I noticed that sometimes my TyTN is working nearly normal, that means it draws 15-20mA with WLAN OFF, i switch WLAN to ON: 150mA, but then when i switch WLAN OFF it starts drawing 350-400 or more again
V87, please post the link to the tool you are using to measure how much power is being drawn from the battery. I want to make comparisons with my unit, just to be sure before I respond
http://www.acbpocketsoft.com/Products/acbPowerMeter/acbPowerMeter-Overview-2.html
It came together with my rom (pays 2.15)
Hey all,
I've been lurking for a while, just picked up a 8525, and noticed some of the same issues. Occasionally, I'll notice the battery getting warm, and after popping up acb power meter, the device is drawing 350-400ma. Turn on wifi, back down to 40-70ma. Wifi off, back up to enormous drain.
I'll shut the device off (long press power button), remove the battery, wait about 5-10 minutes to let everything cool off. Install device, power up, all good.
It's an intermittent issue, and I haven't been able to nail down what triggers the power draw. I'm still experimenting, and will post if I am able to notice any consistency in triggering the issue.
Hey, count me in with that same issue to. I thought it was a battery/charger problem after only getting about an hour out of a batter, but after a new battery and charger, I tried the battery meter program I saw that it was drawing 350-400mA while doing nothing and getting quite warm, but if I enable wireless it drops to 80-90mA. If there was something in that manual that is no longer posted. I would greatly appreciate knowing it.
Unfortunately no. the service manual that was posted includes a procedure for checking the battery voltage with a multi-meter and a test procedure for the logic board that can't be done without service equipment.
I have since sent my TyTN to be serviced for the battery drain issue, and am waiting to get it returned.
I had a similar issue to this. Got my Vario II, charged it up overnight. Next day took it off charge and headed for work. Got to work about 45 minutes later and the phone felt really hot in my pocket. Battery was down to 10%. Same thing occurred over next 2 days so I sent it back, got a replacement and all was good.
After playing with this unit, I've noticed that the high-drain/hot battery starts happening after using a program that consumes high CPU (AOE, flashing, etc). After powering down and removing the battery for a few minutes, and allowing everything to cool down, everything appears ok.
This could be exacerbated by loading the system while charging.
Any EE's with ideas?
Well my TyTN's back from the shop. They replaced the logic board. Hopefully this one won't have any issues
Maybe this was caused by an active 3G connection. I am currently streaming audio over 3G and the power drain goes up to 550mA. The battery becomes very warm as well, which is normal for 3G usage afaik. If you enable wifi, maybe the 3G connection stops and tries to switch to wifi, causing a considerable drop in power drain.
I also noticed that a soft-reset helps bring battery drain down as well. As if windows or the device keeps using power for some background process or something. Not sure if that if a software or hardware related problem tho.

[Test] Battery Draining

Ok, I've been thinking about this for a while now so I'm going to make a test to decide if I really need a battery saver. I'm making this test for myself purely but I thought someone might wanted to see the results as well so here we go.
The gear:
Samsung Galaxy S2, non-rooted
2000 mah Samsung battery
The competitors
Phone on its own
JuiceDefender Ultimate
GreenPower Free
The settings
Prefer Wifi over data
Connect every 30 min to sync
No night settings (to be fair against the others)
Screen brightness: Auto
I know the battery savers are made to save battery when not using your phone so the screen will be locked the phone only used for a small amount of time between chargings.
The phone is unplugged at 100% and I will continue down to 30% before charging again. I will only be testing each one once, as of now at least.
We'll see how it goes over the next days so feel free to ask questions and such.
Many people I know with an S2 use battery saving apps but i really see no point in them, when we used to compare our stock phones running the same stock ROM there was minimal battery difference. Haptic feedback will be off or on? That makes a big difference.
You should put in a custom ROM to see how much better it is compared to stock.
i look forward to seeing the results of this test though
If I got it correctly haptic feedback is phone vibration on touch, right? That's off at least, never liked it. I'd like to put a custom ROM but I don't want to root the phone, yet.. Maybe in a few months or a year...
I will be updating this as we go along. At the moment we are at 96% with 3 hours of sleep time and only a few minutes of screen time.
Ermm, can I ask does task killer drain your battery? Sorry if I ask the wrong question.

task killer will drain battery if the programs you closed restarts, use advance task killer and ignore those that do,you may need it for those apps that didnt close properly
im interested in your trial, juice defender service was failing to run on my s2, it ended up eating my battery restarting the service.
im looking to save power as i lose 15% over night with flight mode while i hear people lose 1,2%
Yes Android is a bit different than computer OS. To start an app drains more battery than just pushing the "back"-button and let it be in stand by so don't use task killers.
Yea I have had trouble some times with the battery saver draining quite a lot over the night but usually it has been because I had a mail as a widget with push-notification so the battery saver wouldn't disable internet but almost push all my other accounts as well. That was my solution at least. We'll see how this goes.
4h in 93% battery
15 min scrren time
A little update. You see where we are.

And does anyone know what can have caused this? This is a picture from a few days ago. It has happened maybe 10 times over the last 2 months. Simply the phone gets hot and the only way to unlock the screen is to remove the battery, refit it and then start it. And then it shows this massive drain.
Okay we got 1 day 13 hours down to 30% with 30 min of screen time. Next up is the Juice Defender Ultimate with night settings off.
An update for you all. As you can see JuiceDefender has already passed the "vanilla" time.
I had an odd problem. Sometime during night, the battery suddelny decided to drain at much faster rate and it took it only 6 hours or so to drain from 75% to 15%. I checked with BetterBatteryStats but there seems to be no app that has kept it awake. Anyway, I can't continue with this test spimply because I don't have time for reruns.
What I can say in previous experience:
Vanilla
Great that as soon as a message comes in you get notified immediately.
Unfortunately that's because wifi or data is kept on all the time, draining battery.
JuiceDefender
Usually gives my phone 3-4 days of battery.
It does take some time (up to 15 sec or so) when you unlock the screen to connect and that can be annoying if you are in a hurry.
When I have night settings on to set phone in no vibration, no sound but also have different night setting time for weekends the phone vibrates once at midnight between weekdays and what JuiceDefender recognizes as weekend.
Sometimes it doesn't feel like the apps are updating even though settings are set to allow "dumb apps" to update as well as plenty of time to do so.
GreenPower
I have only had time to use it for a few days and it is only the free version. I will probably buy the premium soon.
It has a better UI than JuiceDefender though not so many settings. I'm not really sure if I need those other settings.
Best thing, it connects instantly to data when I unlock the phone so I can get on to the web or viber or such to see messages directly.
If anyone wants to continue this thread you may do so but I won't make more test as for the moment. Bottom line is that the data turning off when phone's locked really do help with battery life.

Battery Life Help! BatteryStats LogCat Help Please!

Guys, I am getting terrible battery life on the newest BajaRom. I was getting decent battery life but somehow everything changed. I want to note that I cannot access the Media Battery Drain Fix in the BajaROM settings as it crashes EVERYTIME i open it. I have tried everything to install something that will fix media battery drain but I am unsure if this is what is really causing my battery drain. Please any help would greatly be appreciated!

Wakelock Detector and Greenify... are ur best friends on the Note 3.
Turnoff wifi,bluetooth,gps,etc when not in use. Set CPU to on demand. I always have power saver on unless I want to run a game... doesn't seem to effect anything else.
There are a ton of tips for Note 3 battery life...just search here...
I also use LUX for screen brightness, that made a big difference also. Change you wallpapers to darker colors... mine are some sort of black background...
I can make through the day with reasonable usage on Hyperdrive RLS8 and still have battery left...
Haven't tried BajaROM yet...

Thank you for your response. I have greenify'd most of my daily apps and I use wake lock detector and still cant find out the culprit here. It says that my SCREEN is taking up 30% of my battery life after just 2 hours unplugged and minimal use and I'm down to 82%. Can my phone just be inherently defective????
This DOESNT feel right. I NEVER had any complaints of battery with my NOTE 2

Check your data usage. I had the similar situation, saw nothing in the battery usage area....but then checked data usage. I had over 2 Gigs of data usage from EMAIL in only 2 weeks! I had been using the std email app...and get maybe 10 emails a day. Obviously something goofy going on in the sync. Yet battery usage showed next to nothing for the sync process or email app.
I removed my accounts from the email package, froze the email package and installed AquaMail and my battery usage cut by at least half....my data use flatlined.
Obviously it takes power to use the radio for a Gig a week of data....but that does NOT seem to show in battery usage.
so check your data usage...see if email is way out in front. That may be your problem.

I had the same issue with battery life after I flashed to and of the KK roms. My problem was Greenify, and I don't know why. Removing it didn't solve my problem so I'd restart from the beginning. My drain is less than 1% per hour idle without it and almost 10% per hour running all the same apps with greenify in different settings. Jasmine ROM just drained for me all the time.
*first post, be nice. I only joined because of all the trouble I went through to get my battery life back.

Moto X 1st Gen Battery issue.

I've been experiencing serious battery drain lately.
Lasts around 6 hours tops.
Check out the stats. Anyone know how to prevent this?
Drain is almost 3:40 min / 1% discharge.

Check if your phone turns off the display after the display timeout. I have seen this happen in Moto X sometimes.. It just stays awake. Restart fixes it.
How about brightness? Set it in Auto Brightness mode. Check your Settings->Display page and check all the fields. Apart from that Screen taking 38% is surprising.

I've been having the same problem. I updated a bunch of apps yesterday, (mostly Google apps) and it the battery seems to be better today. It may be too early to tell, but I'm hoping it was one of the Google apps that draining the battery and that it was corrected with the update.
Glad to see I'm not the only one who's battery suddenly got a lot worse. I thought it was Snapchat since I had started using it recently, but the battery usage page doesn't reflect that.
One thing to check is the awake time. If you notice that your device seems to be awake all the time, I'm willing to bet that it has to do with google play services.
If rooted, there is an easy fix via gservices app on market.

I'm having the same issue. Really only getting about an hour of screen time these days. When I first got the phone it was 2+ hours. Mostly use WiFi vs cellular for data, which I thought should be more battery friendly. I make sure I don't have apps running... I'm thinking maybe my battery has just been getting weaker over time.
Here's a good read on battery wear http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
If you charge once a day like everyone the battery decreases by 15% after a year.

Brightness is already set to auto. Also, I've check the settings and display page. Its as it should. I wiped out cache partition and it improved a little. Though I didn't saw significant change by doing that. It still runs for max 6-7 hours. That's it.
have you tried to clean battery stats from recovery?

Doesn't actually do anything. People need to stop facilitating this dumb myth.
Google said:
This file [batterystats.bin] is used to maintain, across reboots, low-level data about the kinds of operations the device and your apps are doing between battery changes. That is, it is solely used to compute the blame for battery usage shown in the "Battery Use" UI in settings. That is, it has deeply significant things like "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."
It has no impact on the current battery level shown to you. It has no impact on your battery life.

May be u need to calibrate your battery. Try to put the phone in charge and let it reach 100% and post that dont remove the charger for 4-5 hours. This is a method to calibrate. Try this and lets see if it helps.
And, I see that you are in H+.. Try using your phone in 2G for a day and observe the battery patterns.
You should clean battery stats from recovery.. Have you tried this?
Mine will drain fast but then it will sit at 1% for several hours before finally shutting off. I have not found a fix and it's been going on for a few months now.

u let the battery die out then recharge to full without switching it on. Once complete boot the phone and when booting is complete then remove the charging cable.

Moto G4 issues after latest patch of Nougat

Hi,
I updated my Moto G4 to Nougat last week. Everything was fine. Yesterday there was some 114 mb ota update. I downloaded it and since then I am facing two issues-
1. Whenever I lock the screen using the power/lock button on the side, the screens becomes black and white for a millisecond and then it gets locked. I haven't seen any other phone's screen becoming black and white for a tad and then lock. Is everyone experiencing the same?
2. The battery is draining just way too fast. 40% depletion since morning. I only used the phone to make two 4 minutes phonecalls. I did not install any new app or game. Any troubleshooting for this?
This is the build number etc.-

Though it's unrelated to this update, when I first got this phone last year I had the same problem with the battery. What fixed it was manually recalibrating the battery. If i remember the steps correctly it was something like: Let phone fully discharge, plug it in and charge it with the power off for about 8 hours, power it on and keep it on the charger for at least another hour.
I updated my phone to Nougat yesterday and manually updated to the same update you're on. I haven't noticed that black and white issue with the lock screen and, if anything, the battery life seems better than on marshmallow. Hopefully battery recalibration helps out. A factory reset may not be a bad idea as well, especially if it wouldn't be a big inconvenience.

The phone charges fully in under 2 hours, thanks to turbo charging. Don't you think 8 hours are way too much? The black and white issue is being faced by other users too-

No. The whole point is that the battery percentage is inaccurate. Here's a guide for you:

When I followed this process I let it charge overnight before turning it back on. I also didn't use the turbo charging charger that came with it, but instead a 5 port Anker usb charger. Perhaps I wasted time, but it worked.

Thanks. Will try the same.
That second photo of S6 looks scarier for a phone with non-removable batteries. Is that the case with most of the phones with non-removable batteries?
