battery draining too fast new or old

im on a stock rom not rooted and new battery and old battery both discharge really fast. Totally dead in 5-6hrs light use. Im guessing there is a hardware issue with the phone as this isnt normal. Any ideas?
lets see I did a factory reset after Jellybean update
changed the battery for a new one
biggest power drain is showing up as screen 33-39%
I have the thing on power saving mode and mobile data I turn off when not in use.
only thing I can think of that I didnt try is flashing another radio. But I doubt thats it because ive put it in airplane mode and it still looses power fast.

Get Better Battery Stats and check your wake locks. A lot of information in that thread. Might have a rogue app draining you.
Edit: also screen on is always going to be your biggest drain. Keep brightness down as much as you can. App called screen filter is good for achieving lower brightness than system allows. You could try the ktoonsz kernel, undervolted as well. Turning off sounds in settings (key press, vibrate, etc as well). Toggle data and WiFi when not using. These are just some basic suggestions.

This is my second s3 and the first one never had a problem going 10-12 hrs normal use. Im thinking it is a hardware issue as I did a factory reset and it still persists on fast draining.
Edit.. I just disable google talk maybe that was causing it?

It's not Google Talk. Check your battery and it'll show you what's drainage ng it the most. Also check screen brightness

well after the screen 40% we have android OS @ lower 30%

Do you have an SD-Card in?
I was getting the same battery life, took out my SD-Card, and I'm getting 7 hours on screen time with stock battery.

lol sd card?? well I tried it anyway and no, it still drains like a pissing racehorse. Ive noticed this phone gets pretty warm sometimes even with light use. Im not sure what is causing this but must be a factor in why the battery life is so poor. When I talk on phone, not very often, the ear piece actually gets hot. Im gonna send this puppy to samsung and see what they can do.

GSam Battery Monitor can offer better details about your battery usage, including wakelocks, cpu usage, etc.. It's more detailed than what Android offers.
I'd also recommend using an AOSP based rom as they include out any carrier/Samsung services that may adversely affect your battery life, particularly in a fringe coverage area or with many sync and push items. I'd also stay away from powersave mode for the time being.
If you want to know for sure, I'd do something like this:
- update PRL on current rom
- wipe and format everything in CWM
- flash rom as per developer suggestions
- wipe battery stats
- boot and do not sign in with your Google account (very important!)
- do not install or restore any apps
- turn off auto-sync and leave data on
- enable auto brightness
- confirm that phone signal is somewhere between -50 and -90dbm
- turn off phone and charge overnight
- turn on in the morning and use normally for the day
- install GSAM if issues persist
Please post back with updates.

It could be a hardware problem also you know.... if something ground off in the phone then the battery will drain faster than anything....I had a n96 with a grounded problem and it use to dead in 4 hrs....

remaining battery

why in power managment, the time on battery left is totaly wrong??
when it says I have 2 houts left, m battery is empty in 10 mins. why is this??

any replies please?

Provide some more details. What firmware are you on. What performance mode are you on. What did you do with your device. What exactly was 2hrs left ? If you go to power management, on the bottom there is an option for time left details for each specific function you use like calling and browsing. Also the standby time being so many hours does not mean you can actually use the device with the same amount of time. So endurance mode might give you hours of extra standby but using the device would drain the battery as usual.

The 2 hours are based on your average use. The phone doesn't know in advance how it will be used. If it is just laying on the desk it could work another 5 hours.If you are playing a heavy multi-player game, the battery will be enough just for 5-10 min.

I am on b111. Please look at my screenshot, Loon at the time left for movies. I can get 2.5 hours out of the phone, but it says 4 hours.
Also the average use you talked abought in previous post, my phone dies faster than the time left said on standby. What tweaks do you guys suggest? The battery life sucks!! Will b122 give alot of battery improvement? Thanx alot for the replys

B122 is more stable and bug free than b111.
Check if there are other apps draining your battery in the background like google apps sync or autoupdates or location service.
Gsmarena tested our device (most probably on earliest buggy firmware) and they got video playing time of 7hrs: http://blog.gsmarena.com/huawei-ascend-p6-completes-our-battery-tests-here-is-the-full-breakdown/

Set your display brightness to minimum, turn off WiFi, mobile data, synchronization, BT, GPS, screen rotation, background data and so on and test again.

Sorry I am new on this phone. I had an Galaxy Ace till a week ago, I flashed hundreds of roms, kernels, experiments. but on this phone I am afraid of brickin. Its an expensive phone. so I havent even rooted it. I cant seem to find an official B122 firmware. only leaked. so I am affraid to flash it. And I cant find an step for step guide.
Also, my mobile data is on and auto rotate. I have to keep this on otherwise there is no point for me to have this phone.

The bricking happens only with Chinese version roms and not interntional version. And only b111 is official international version. The rest are leaked.
The guides are available as pdf file, when you download the B111 from Huawei website or you can find them at huaweinews.com. And the method is same as how you upgraded to b111.
Yes sure, but it is matters like that which drain the battery more than what it says on the power manager.

[Q] N5100 Battery Life

Was skeptical about the N5100 battery life since it only have 4600mAH battery.
Now that I have bought it, it seems my worries are confirmed.
I'm running stock rom, only rooted it without other modification.
Installed and have greenify running. Not using any sim card, only using it on WiFi.
Playing a video using MX Player, drained up about 20% of battery for a 45min video. That's rather heavy imo.
Normal browsing and reading forums eats up about 4% per 6min of use.
Is this normal? Or is it my battery has significantly degraded? Cuz I bought this 2nd hand 8 months old.
Btw the above test were with Power Saving mode(CPU and Screen) and screen brightness was at 25%~30%. Currently on 4.2.2.
And does using the S Pen eats up significantly more battery?
Thanks in advance for the feedback.

Do a search on battery and charging by me, in the Q&A threads. I won't repeat myself here, but I go into how to correct drain issues. Many developers will push their apps for calibration. The real trick is discovering what is doing the drain. I have seen for myself how one app can do a lot of damage with media. Normally I get 12% per hour on battery usage while Miracasting Netflix to my tv, and about 10% on normal usage with WIFI always on. I have MXplayer and a bunch of apps as well running so I am not going to get the same power savings as with a cleaned up stock ROM without any apps, what would the point of having a tablet if that is the case???? I guess peeps like to show off when it comes to numbers. I like to show off when it comes to usability and function without all the apps get in the way.

my battery stats
I'm running CivZ-FLEX-BEAM-REV3.6.2 ROM.
Installed and have greenify running. Not using any sim card, only using it on WiFi, even off the WiFi before I off the screen.
Even use underclock to 1.2Ghz cuz only used for normal browsing, nothing intense that require more power.
Here's my battery stats:
Is this normal? Or is it my battery has significantly degraded? Cuz I bought this 2nd hand 8 months old, now 9 or 10 months already.
Now considering should I replace the battery or just get a powerbank to help.
Thanks in advance for the feedback.

From what the graphs show... it looks like the battery could be going bad, as there has some that say Samsung is aware of bad batteries in some units. You could contact them, but you will need to un-root if sending to Samsung for repair.
Since you are rooted, I suggest installing xposed framework and install Wanam DVFS Disabler for Xposed. It is a standalone utility from the complete Wanam xposed app. Once installed make sure both xposed is functional, and the app in xposed is enabled. These apps act as a separate process from the OS. So installing them requires user interaction for activation and updating, along with a reboot most of the time.
Once they are running... it is best to turn off the tablet for 1 minute and then plug in the USB charger and wait til it is showing 100%. Then turn on the tablet. You can unplug the USB power cable and wait 1 minute, then plug it in. Take note if the charge takes less than a minute to get to 100%. If it takes a minute or more... you will need a stop watch, as it should take about 15 to 20 seconds to go to fully charged, unless you have music or media running at the time. If it does charge quick, you can then disconnect and do another days worth of use and check your stats. Hopefully disabling DVFS will cure your issue if it is not battery related.
As for unrooting, make sure you do a clean uninstall, and have any apps that require root uninstalled. If running triangle away uninstall that as well. You may have to check within the apps settings to make sure you uninstall properly, as to uninstall from play store or the system may not properly remove the app.

Updated Battery Stats
this is my updated battery stats, now I'm suspecting it maybe due to calibration problem?
My screen on time is now 2 hrs 45 mins, and for the last 45 mins it has been running on that last 1% of battery(but with screen dimmed, as brightness is automatically dimmed and can't be adjusted when below 5%).
Even until now the device haven't auto shut down due to run out of battery yet even though been running 45mins SOT for that 1%.
Calibration problem? I've tried calibrating using calibration apps, which I charged to 100% then press calibrate, but didn't help.

Sudden drop of more than 3% at any level after doing the DVFS disable and properly charging can be one of two things.
A bad battery, or bad charging cable. Yep, I have had two bad Samsung cables, one did exactly what is happening with you, and the other did a melt down at the USB connection on my tablet. If you have a good cable from a Blackberry or a Sony/Ericson device, you can try that. I have moved over to Sony Xperia cables, as they are pretty well built and longer.
If another cable does not solve your issues, I suggest unrooting and cleaning up rooted apps before having Samsung service your tablet. It very well could be a bad battery.

thanks for the reply, I think I'll just resort to sending it back to Samsung to fix it.
Now I have made a nandroid backup already, then I flashed stock firmware, so my device is now unrooted and on stock firmware, however my flashcount is still there, and now I can't run triangle away cuz my device is unrooted already.
If I were to root it, it'll flash custom recovery again then it won't be on stock firmware anymore.

Your unroot sequence was done out of order.
Set USB debug
Root stock rom with saferoot.zip
Install triangle away
perform clear of counters
Verify after clearing in about device that custom is not set.
If so make sure triangle away is set to clear and perform clearing.
Remove triangle away
Remove SuperSU through the settings, clear for reinstall.
To make sure everything is proper... do a factory reset.
Once those steps are done, your tablet should be stock and able to perform OTA or Kies updates, without any issues with counter and root.

[Q] 4.4.2 Battery Life issues - less than 25% total life compared to previous version

Hello, new to the forums here. I recently updated to 4.4.2 on my LG Optimus G Pro and I went from having a battery that lasted all day, sometimes two days to my phone being dead by the time I get home from work for the day ever since the update.
Two days ago I had 1hr18min of screen time within a 6 hours off the charger and the phone was at 15% battery life left. Today, I had 13 minutes of on screen time and at the end of my 6 hour shift my phone was at 40% and dead a few hours after I got home. I have GPS, bluetooth, NFS all disabled and my brightness set to 30%.
Any help would be greatly appreciated, I'm thinking of doing a factory reset and just not updating to the new version of android when it prompts.
Thanks

Get betterbatterystats and see if you phone deep sleeps. If not then check what the wakelocks are in partial wakelocks. If it's a kernel problem maybe you need to flash a different kernel.

i am running stock phone. it is not rooted or anything

Same exact battery drain problem. Im on stock e980 rom (rooted) with no custom kernel.
Gsam battery monitor app is showing the kernel as keeping my phone wake for the entire time my phone has been unplugged.
The problem seems to come and go though. One day itll be fine, but another day the battery will be sucked dry fast.

I'm running stock rooted for e980 and have pretty good battery life .... Try clearing Google play services data and rebooting ... Check and see what's draining your battery mol its pretty easy

I've done this twice in the past 3 days....
I'm sick of having to set up my phone over and over again. And this is a new phone too. I just got it Monday under warranty because my old phone broke.
It's getting annoying. I used to get 14-17hrs+ of battery life (casual use, usually ending the day at 30-50% too, so I never even reached 0%) with my old phone on Jelly Bean. Now with Kitkat, I get around 6 hours if I'm lucky! According to Wakelock detector, my phone is awake 85%+ of the day! All it points to is Kernel (Android OS). I see lots of Wlan_wake triggers too, so I suspect wifi, but even with wifi off, the drainage still occurs. And I only have a 2GB data plan shared between 3 people, so it's not like I can just use data all the time either. I actually NEED wifi.

do you have an SD card installed? Maybe you can try to remove that and get rid of all other media from your phone storage. Might be a media scanner problem? Or maybe you can try to disable auto sync, and check if Google play services is the culprit.

The media scanner usually shows up in the battery stats window though, and it isn't. I've had a corrupted SD card on my tablet once before and it caused media scanner to go berserk, but the Mediascanner entry appeared under Settings>Battery as the highest battery consumer.
In this case of my phone right now, it is Android OS in Settings>Battery. According to Wakelock detector, GSam, and BetterBatteryStats, it's more specifically Kernel.

Hi i had the same problem as you but i started digging inside the system of the phone i found the problem but you will require root access. If you have root you have to delet a lib file tand it carrier iq wich run in background and drains your battery the file to delete is libiq_client.so do that and you will see an increase in battery life

I did this on Tuesday or Wednesday.
... I messed something up on my phone while trying to install a custom recovery, so I was basically forced to reinstall everything. I'm on stock ATT e980 ROM (on an E980) + root. I reflashed the Jelly Bean tot file and then did the OTA update with no apps installed.
On the phone that got warrantied, I had flashed the E980 kitkat backup (now has a flashable version too), and the battery life seemed to be much better on it for about a week, and then the issues started there too.
I just rebooted the phone into recovery and wiped cache and Dalvik cache. Many people on Kitkat are reporting that this helps, but only for about 2 days then the issue returns. Obviously, I want a permanent solution.

Yes, I'm rooted and I absolutely hate custom roms. They take out all the features of the phone that I originally bought the phone for, like Smart Screen, the IR remote (yes, I know it can be ported), and the quick memo button. Plus I used custom ROMs on my old SGS2 and they always caused me tons of problems. Crashes, overheating, random reboots, random SODs, etc etc etc. Plus I hate the AOSP feel. I know it's true Android, but I just don;t like it.

I'm still getting more than usual battery drain, but it is better now.
I just got a replacement OEM LG battery, so I will try that to see if maybe the battery is defective. When I got my phone replaced under warranty, they didn't have batteries in stock, so they just gave me back my old one and ordered me a knew one. The old phone was overheating a lot too, so maybe the battery is bad.
UPDATE: OK, MUUUUUUUUUCH better battery now!
I put in that new battery and "recalibrated" it by draining it to 0% and charging with the power off. Once it reached 100%, I let it charge an extra hour, unplugged, and started up the phone.
I also installed Qualcomm Snapdragon's Battery Guru. I set it up so that it's mostly managing app syncing, but I also set it up so that it will not rely on location services to turn on/off my wifi. I don't want to leave my location services on all the time. I don't know how it is on Kitkat, but on older Android versions (ICS and GB), leaving GPS on was a huge battery drainer! I still treat location like it was back then.
Anyways, it will take a few days for the app to learn my usage patterns, but it's already helping by making certain apps only sync when I open them, etc. I suspect that all the wlan_wake wakelocks are being caused by auto-sync but I'm reluctant to turn it completely off since i rely on it to sync my work schedule, calendar, etc between my phone and tablet. I just wish there was a system setting to allow auto-sync to run every X hours or something. I really only need the sync to run every 6 hours or so.
It's been about 35mins now with 6mins of screen time and the phone is still at 100%. A few text messages and the installation of Battery Guru too. This is normal and how things used to be. After a while, the phone will most likely go to 99% and then have faster drain, but it shouldn't be so rapid like before. Earlier today, after 30mins, the battery would be at at least 95% or lower by now! After a full day, the battery usage graph would should a 45 degree angle too! It used to be an almost level, very gradual angle instead.
I should also mention that for a while, I was using a Zero Lemon slim battery (3150mAh). I bought it because of all the hype Zero Lemon was getting here on XDA, but I really regret it now. I used it for 2 weeks (1 week on my broken phone and 1 week on my replacement) and the drain wasn't consistent, even after several calibration attempts. It lasted me all day though, but I'd be stuck at maybe 3% for like an hour, then while in deep sleep, the battery would "magically charge" to 6%.
After I swapped back to the OEM battery, I don't think I recalibrated, so I wonder if my phone thought I was still using the Zero Lemon.
I'm planning to return the Zero Lemon.
UPDATE2: It's been a couple hours now and the Android OS is starting to retreat from the #1 slot in the battery consumption list!
Screen is #1 now and Android OS went from 65% usage to 14%! :good: :good:
UPDATE3: :crying: OK, it's broken again. I didn't do anything to the phone, but when the phone hit 50%, I left it alone for 2 hours and the battery drained 30% while it was supposed to be sleeping. Android OS is back up to 80% usage!
Wifi on, Location off, Bluetooth off, auto-sync on. I'm trying auto-sync off today to see if there's any dramatic improvement.
UPDATE4: I might be on to something now. I noticed 2 things: 1st, when the screen is off and the phone is SUPPOSED to be in deep sleep, the back of the phone stays warm to the touch. It wasn't hot, but it was warm enough to be noticeable. 2nd, I had System Tuner installed yesterday but uninstalled it this morning. Despite uninstalling and rebooting, the phone was still draining battery fast (I still lost 25% in 2 hours today!). I noticed that System Tuner had added a script to System/etc/init.d, so I deleted that and rebooted. Now the phone seems to be sleeping (says so in BetterBatteryStats and WakeLockDetector), and the back of the phone is COLD to the touch when doing so. I took a shower today (I take fairly long showers too LOL), and then checked my email, and the battery life didn't decrease at all during that time while it was asleep.
Obviously, I need to test this throughout the day now, but this is definite progress, if not the solution.
Also, on my warrantied phone, when I had the Zero Lemon battery inserted, battery drain was high (battery's fault), so I installed System Tuner then too, trying to tweak the phone. After switching back to the stock battery, the drain remained, but most likely due to System Tuner's script.
Then when I got my replacement phone, I ALSO installed System Tuner and of course, I got battery drain issues! I factory reset, but did not install System Tuner, but the problem still remained. However, it probably remained because the reset doesn't remove system files, so this script was still in the init.d folder.
FINAL: I ended up flashing the stock ROM again (I used Eazy Kat 1.0 this time). My phone began bugging out on me. Random crashes here and there, mobile data randomly disappearing (no LTE/4G/3G at all), and worst of all, people were having difficulty hearing me during calls. Reflashing seems to have worked perfectly this time. *knock on wood*
FYI: The last flashes I did, I used .tot files to flash back to stock Jelly Bean and then updated to Kitkat via OTA.

Hi i had the same problem as you but i started digging inside the system of the phone i found the problem but you will require root access. If you have root you have to delet a lib file tand it carrier iq wich run in background and drains your battery the file to delete is libiq_client.so do that and you will see an increase in battery life

I stumbled across this post and tried that fix. I'll check back in later to see what it does.

[FIX] Battery Drain,No Deep sleep, Android os wake-up all time

Tested on Lineage OS14.1, PurefusionNougat, CRDroid (not tried in other ROMs, it may work)
After trying a lot of modifications in two weeks regarding battery drain due to android os wakeup all time and little or no deepsleep, found a simple way to solve the issue.
1. Calibrate your battery according to post #9 (https://forum.xda-developers.com/showthread.php?t=2765663)( (Essential- it will fix almost all errors regarding battery)
2. A simple build.prop tweak wifi.supplicant_scan_interval=200
Add this line to system/buildprop using a root explorer with root permission " wifi.supplicant_scan_interval=200 " and reboot.

Screenshots after applying the mode

I edited the build.prop file via BuildProp Editor in the app store. So does i add that line in the beginning of the file or at the end?

do build.prop edits need a reboot to work ?
But yeah... WiFi has always been an issue on the HTC10 -.-

Battery Caliberation that also worked for me according to this xda post by @bikercr https://forum.xda-developers.com/showthread.php?t=2765663
Thanks to @bikercr
His Post
"This is directly from HTC tech support. To recalibrate battery and HTC charger when battery rapidly or erratically discharges, this procedure clears all battery stats, coordinates and normalizes charging.
Turn off Fast Boot in settings. Power off phone.
Plug phone into HTC charger and charge for two minutes or more
While charging, hold down volume up+volume down+power button and continue holding
Phone will turn on and off repeatedly every 15 seconds or so while continuing to hold all three buttons
Keep this going for 2 minutes, then release buttons when phone is ON
Now, let phone charge fully normally (with phone either on or off--doesn't matter) and battery level reporting, charging and battery life should be normalized.
Do this every month or so to keep power system healthy--even if everything seems fine. Also, don't leave phone on charger overnight for best long term battery life (according to HTC tech support: "The first thing they tell us." This is true even though charging is supposed to turn off when battery is at 100%)
NOTE: Another potential fix for battery/charging abnormalities if this procedure fails (esp. after an OTA update when corrupted files can remain stuck in device cache partition)--clear cache partition using this method: http://forums.androidcentral.com/ver...ted-phone.html"
New screenshot attached- Still 100% after 59 minutes (Note: without Gapps) Running crdroid from @andybones

Good morning, the fix works with Leedroid Oreo?? or is it for Nougat AOSP ROM?!
Thanks...

Tested only on Nougat, But it will work on Oreo too, Do the battery calibration first.

So how is your SOT after this fix?

This fix increase standby time (battery drain and no or little deepsleep due to android os awake all time)
This fix have little impact on SOT. SOT depends on many factors like Screen brightness, Surfing on 3g, 4g or wifi, playing Games, watching videos etc.
A Little Story
I bought this device through OLX and the seller selling it due to poor battery backup and warmer device even in standby. Due to interest in tweaking and modding from my first android device(Samsung spica 256mb RAM!) i bought it (with Android MM). Found the device doesn't enter in to deepsleep and android os is in the top of battery consuming. Two weeks of flashing differnet roms, Kernels, tweaking kernel through Kernel adiutor app, disabling and removing of apps , build prop edits etc. One day i noticed that my device goes to deepsleep almost suddenly after locking. Flashed the device again and do the tweaks one by one to know which tweak give me the result, and found the wifi scanning interval build prop tweak is the reason.
And it runs smoothly almost all time and some time it shows battery drain. So done some more googling and found this post in HTC One (M8) forum https://forum.xda-developers.com/showthread.php?t=2765663)(. It realy helps to completely overcome the Battery drainage issue. Then i tried almost all nougat roms and all of them are giving excellent battery backup.
Now my device have no deepsleep battery drain issue and now trying some bloat removed nougat stock.

Yes i tried today i take my phone away from charger 6:30am
i made some screens.,. will upload later
first of all, it was defintly better than last 4-6 weeks...
battery juice goes down from 100-0% not like 100 to 98 to 86 to 80 to 52... u know that % jumping around, reboot between 19 and 23% and so on...
but i have had a screen on time of about max 2 hours and my battery was down after 8~9hours... -10%battery per hour in power saver mode with lowest brightness
heere my results :
6:25 100%
74% after 2h30m with screen on 21 min
45% after 6 hours with 52min screen on
12% after 9 hours with 1h16 screen on
3% after 10h15min with 1h18m screen on
after the 10 hours i have had battery usage:
40% Mobile Network Standby
29% Apps
15% System
6% Phone inactive
it was defintly better than before but i have had also the battery draining... btw im on lees r143 with cleanslate kernel....
i install elementalX Kernel with a bit of uc and deactivate some stuff i dont need i will test it tomorrow and report....
maybe we find a solution together....
sorry for bad english:cyclops:

40% Mobile network standby is due to low network coverage and network use more battery to establish a good connection.

on my phone , wifi running is always 100% , I think that is "always scanning option enabled", so this option is draining my battery?
or
which I sacrifice doing your method to my phone?
(Im on LeeDroid R147 Oreo and battery tip is done. )

wifi.supplicant_scan_interval=200 if you switch on the wifi always scan mode, then wifi trying to search for available networks all time, if you add these lines to buildprop it pause 200 seconds between scans and it help to reduce battery consumption, drawback - time for find a new wifi hotspot may increase.
