Battery HELP!

i dont know why... but the battery of x1 lasts only a day!
and when i think about... i'm pretty much a light user.
i dont use the wifi and 3g at all.
the brightness level of the screen is the lowest.
i play music about 2 hrs with the earphones.
i hardly use any apps except for windows media player.
that also about the 30 mins the most.
i only use the internet about the 30 mins the most.
bluetooths off.
i always close any open app that is there via the htc taskmanager
i using the htc touchflo ui.
i take about 25 pictures at the most and no video recording.
maybe the settings of my phone is somewhat wrong.
maybe i missed something.
so anyone.
please help me...
any advice? any tips?

Then you have a normal battery usage
Wich wm do you use wm6.1 or wm6.5 ? i noticed better battery life in wm6.5 if i don't do anything on the phone the battery lasts for max 2 days but only if i really do nothing on the phone. i have to charge my phone every night.

Sounds pretty normal to me .

these are the batt killers
if you stop doing those it can last 3 days
but as with all such devices charging them a bit every chance you get
is good for then and give you a longer batt life
it charge using a miniUsb which is everywhere otherwise you can
get one to carry around in a shop for a few $£€
so any computer with usb can be your temp charge station

Okay, I've got some advice for you maybe. I have just flashed my phone from R2A to R3A nad haven't installed too much applications yet, only PocketShield, Resco Explorer and Spb Phone Suite. I notice a strong increase in battery life compared to the old R2A with sooo many apps (Although basically none were running in background, at leats not ones you would think that they consume much power). So I don't know if it's the apps or the ROM but my battery lasts about 75% longer, which is approx. 40 hours total. I have about the same usage you are describing.

and dude.
did you read the reviews.
the phones battery is suppose to at least last 2-3 days.
cause it can/ and should last 5-6days.

yes, i charge my phone using miniUsb cause i'm always with my laptop.
haha.
plus it makes it easier for me to charge.
but the phones battery draining faster and not lasting how the reviews said.
i seriously am going to do some experiment now.
thanks anyway.

I'm just telling you my experiences. Yesterday for example, phone was fully charged @ 7.00 AM. Been listening to music for about 5 hours, called my girlfriend for 1.5 hours, had pushmail activated all the time, sent some text messages, got an email, battery was @ 30% at midnight.

Certain laptops have "battery saving features" which regulate/cut off power delivered to usb ports. Try charging with the wall charger.
Plus the wall charger charges faster.

sorry but htat battery life is in standby mode. calling uses not that much battery life because the screen is turned off. if you using ur phone extremly thna the battery will drain very fast. with winmo 6.5 teh battery life is 2 days but i dont't take pictures i listin to music about 1 hour and sometimes i'm surfing on the net with it. it checks every 1 hour for emails.
i had so many wm phones and all failed the battery life. they had all short battery life ofcourse i want my phone to last 3 days with the same usage like urs. thats why i have a spare battery with me always.
the battery will drain also faster if you using a lot of apps in the backgound. with a clean rom the battery life is longer than that i install a lot of stuff on it.
So my conclusion is that the battery life will be different for each person. if you think ure battery isn't good than i would say go and buy mugen battery 1800Mah i did it to and i'm happy now.
I did some tests with the original SE battery when i don't do absolutely Nothing with the phone and its in standby the phone battery lasts easy for 4 days

OMG.. 1 day is not enough? OMG!!!
Makes me wonder why we sell Xperia in countries, where they have no access to electricity..
Well, I can recommend buying another phone, or even phone with some solar charger, if you have no access to electricity. Or another battery would do fine.
Myself, I use WIFI a lot in my work, call about 2-4 hours a day and sometimes i'm listening music while walking home. I charge it overnight (yeah I'm lucky guy livin in Europe with access to electricity).
And sometimes it makes me wonder, that people expect the battery to be like nuclear power plant - once you start it, it'll never stop giving you electricity. Cmon, you have 500Mhz CPU, big screen, GSM+3G running at once. Then you can turn on WIFI, GPS and the CPU goes 100%. 1 day is not enough? Jeesh.. Show me a device which lasts more than one day WHILE USING IT (so calls, messages), with normal battery (no nuclear power plant, please! ) and I'm yours
Some people (no offence!!) should return back to Earth
To save some battery, turn OFF 3G if you're not using it. But that'll give you just few hours, which won't save you that much.

2 Hours of GPS use sets me to nearly 50% battery gone!

Yeah, coz you're using GPS, then the screen is ON, the navigation APP (ie TomTom) is using CPU nearly to 100%, then also the GSM-3G is working all the time, RAM and apps in RAM are draining as well.. Normal

Hmm.. i'm not quite sure right now how about X1.. But if I am not mistaken, few months ago I tried GPS with phone OFF and it worked EXCEPT TomTom. It found sats, but TomTom refused to accept it. But geocaching app worked.. Will try tomorrow or the day after tomorrow.
Not sure about sat navs, don't have one. My parents do, but they always plug it into the car as far as I remember. But I don't think any sat nav will last several hours with battery, when there is CPU clocked crazy high, bright screen and also the GPS chip itself (not mentioning that the heat will decrease the battery life).

i know what you mean...
but i think mine will last about 9hrs.
which i still find... very less!

Calibrate my battery

Which is the best style to calibrate my battery? I't only lasts for 10h.

10 hrs is pretty good
i only get 4 hours under heavy use

I forget which thread it was but it said to completely discharge until the phone switches off (ignore please plug in prompts) and completely charge it back up 5 times. It worked wonders on mine
4 hours? pah, i can kill mine in under an hour lol
seriously though, it all depends on usage and how much you have running on the phone (big widgets and social feeds for instance), screen brightness also has a big impact.
On average i get a day out of mine but my mums boyfriend, with the same phone uses it far less and has had 3 days from his on one charge

Ok i'll try your method. Thanks guys!

I have mine going down to 79% within half a day,only standby and frequent switching on of the screen, is it normal? Thanks!

So which one of these two methods is the right way to do it?
EDIT: And how good is this guide?
1. Run the device down until it turns itself off.
2. Turn it back on and wait for it to turn itself off again.
3. Remove the battery for 10 seconds.
4. Replace the battery, but leave the device off.
5. Charge the device until full and then for another hour.
6. Boot into recovery and reset battery stats (or, go to console and type “su” enter, followed by “rm /data/system/batterystats.bin”)
7. Run the device’s battery down until it turns itself off.
8. Charge to full while off.
9. Restart and use as normal.

IMHO, the battery stat is just pure witch doctor style..
Id recommend you use the phone till it drops down the 2% then power it off and charge it while its off.. that way it MAY take upto 4-5hrs charging when it says its full remove the battery for 1-2mins then install it again and charge it while unplugged its gonna charge for ~5mins and when its full disconnect the charger and power on the phone.. you just need to do this once ( on my experience ) and charge as often as possible since its not a good idea to keep draining lithium batteries

Make the phone empty.
Charge it all night (8 hours + ).
While still charging, open applictaion: Terminal Emulator (it is available on the market for free)
Write:
su
rm /data/system/batterystats.bin
it looks like that nothing really happens, but it does.
Reboote the phone. Important!

There's another method^^
I really don't know which one of the 4 battery calibration methods that I've mentioned above I should use?

I've read from many sources to not worry about frequent discharging/charging of your battery. The lithium-ion batteries we have in our phone will degrade based on cycles (when a certain number of charge cycles have been reached). As for overcharging, the phone is smart enough to stop charging once the battery is at 100%. The battery will slowly discharge, and once it hits a certain point between 93-98% it will start charging again.
As for which method works the best...I'm struggling with the same issue. Personally I've tried almost every method other than the reset battery stat (which I plan to do as a last resort).
I have found that the battery gets better after a few weeks of use. The full discharging/charging does help marginally. The turning on and off method of charging also helps marginally. The biggest culprit is usually background apps preventing your phone from properly sleeping or activating your data when your phone is locked. I was using juice defender and my battery still drained crazy. I JUST changed my juice defender to turn on data for 2 mins every 30 mins (as opposed to 1 every 15) and it seems to have made my battery better. Before I did this, my phone drained 40% in 6-7 hours (while i was sleeping). Right now... my phone has been active for 5h48min and is at 72% (a bit of texting, a bit of 3g, and wifi). Here's hoping it'll get better.

This thread helped a lot
My phone drained 70% of battery from 5am till 12pm (while I was asleep). When I saw the battery usage stats it said that Android OS draind 68% of the battery. I flashed the phone on sunday. I should do a calibration then, right?
I'm going to try this method:

Theory ROM 1.7 battery issue info

Hi All,
I'm a new registered user, so I can't put this in the developer forum yet.
I noticed a problem where I was losing battery power quickly, so I foudn a posting that said to do a "super" wipe. This was to one click recovery to stock, root, bootstrap, then boot into recovery to wipe cache, data, dalvik, format /system, wipe cache, data, install theory ROM 1.7. after clearing dalvik the second time, I threw in a "clear battery stats" for good measure.
What I noticed was this: prior to attempting any of this, the phone reported to be 96% to capacity and said it was "full" so it wouldn't charge any longer. After doing the sequence above, upon initial boot up, the battery was now reporting 88% and was charging again.
It would seem like the mechanism for reporting the battery usage is flawed in some way.

I am running a few days of testing but the calibration methods are to drain fully, and charge (while device is off) to 100%, unplug and before turning on, charge additional. Before my full charge read 95%, on 1.7. I did the above and now it read 100%.
From the beginning, here's how my battery life was:
Day one: full drain with performance mode, I received 8-9 hours. Used maybe 60 mins of voice, email sync w gmail and touchdown, sent about 100-150 texts. Watched 2 episodes of the community streaming from zumocast on 4g radio all day, used Pandora a few times.
Night one: night time saver mode, this is where I discovered my full charge was only 95. My night time mode activates at 10pm, my "full charge" completed at 7pm, used Pandora
On the ride to the gym, had minimal texts, email sync, twenty min phone call, 4g radio on. Went to bed at 10pm left phone idle, no charge. Woke up at 630am night time saver ends at 5am, device reported almost 12 hrs idle time, 40% battery left. Pandora to work, 4g only, synced mail, browsed YouTube, Facebook, no calls. phone full drained around 1140am. So almost 16-17 hrs on one charge, but the high light was 5 hrs from 40% battery... Last to note, I never turned off blue tooth.
Currently, after full charge 100%(not like previous 95) I'm at 1hr26 mins and at 85% bat...same usage, same battery mode
Ill get further results soon.
Update: now at 55%, 3:55hrs on track for about 8-9hrs ... Not using app killers to add or any battery apps. Problem seems sporadic but I'm going to try to run full battery to full drain on performance mode to optimize..in my past experience Droid 1 and Droid x, over time the battery adapts or the phone adapts to the battery usage ... Could be a myth or fantasy ...

Thanks a bunch for the info. I am in the process of doing the full drain right now. Hopefully, it will show some results.

Our phones read fully-charged at 95 percent, but if you keep it plugged in it will get to 100 - it just takes a good while.

There's a trick to that. Yank the back back cover, pull the battery, and unplug the phone. Plug the phone back in and wait for the "missing battery" icon to show, then slide the battery back in. It will initially read 5%- wait for it to charge to full, which should take 10-15 min. Repeat this process until the status reads 100% charged within a few seconds of putting the battery back in. Reboot into CWM and wipe the battery stats (or use the battery calibration app that's on the marketplace, if you don't use CWM) and you should be seeing a batter that's not only noticably more accurate in its charge level, but also charges more completely, resulting in somewhat better longevity.
You want to drain it fully and let it charge back up fully at least once after this process for best results.

This is a good trick, one I was taught by juhde. I used it on my x2 to great results.
However, I can't get it to read on my bionic. I get the '?' but nothing after I reinsert the battery.

I find it only works when I unplug it and plug it back in just before inserting the battery. It sometimes also helps to hold down the power button for a few seconds with both the battery and charger out in between 'bumps'.

my fix
I have flashed every update since the first post and had battery issues starting around 1.5. After reading through the dev thread a bunch it seemed as the when performing wipes, they did not come out "clean" after one wipe. So I started at one wipe of each (factory reset, system, cache and dalvik) and the problem persisted. I then did 2 wipes of each, then 3 and 4. after 4 wipes of each all my issues had been resolved. not sure if it will work for everyone but it was the turning point for my device and might be a good starting point for anyone who is as annoyed as i was. good luck!!!!

Update:
Was able to repeat 17 hrs with custom settings: data off @30 min peak/off peak. Blue tooth was on the entire time, cell idle and Bluetooth were 30% consumption each.
Right now I'm in full performance on track to do 9.5 hrs. I've been playing Pandora for an hour every other hour, and did not kill its process.
I think the most practical usage is to cut data when not used for 30 min, I couldn't imagine anyone on their phone doing multiple things for 8+ hrs STRAIGHT. I'm running unleashed 1.7, no radio problems and no slow downs.

My brother has been getting twice the battery life that I am getting. The only difference is I have rom installed, and he just debloated. I have a switch out extended battery coming from Verizon and if that doesn't work I may just drop back to stock debloated.

I think I have a faulty battery, I can't last 5 hours on a battery anymore. I'm going to go to VZW and see if I can pickup a spare and test that one.

This rom has absolutely nothing going for it. v1.7 and $6 will get you a cup of coffee from Starbucks. I have never flashed to stock as quickly as I did with this rom, since my first smart phone. Is this guy/team the only Dev with a Bionic??
Downloading/flashing on the fly (streamlined) is great however, what are we going to flash folks? 1.8??
Yes I know theory is only playing the hand he was delt but its clearly time to fold.
This makes me nervous.
For the issue regarding battery life..flash back to stock. Wait for the next developer.

Yeah? And what was the issue you had? ANY ROM you flash will nuke the battery stats and need to be recalibrated. Simple as that.

Sorry, yes it was at 5% when posted that, and that was right before my car ride with Pandora playing through Bluetooth.
The end time was 10hrs 35mins.
Since then, I have done a 4x complete wipe, cleared previous traces of unthrottle and flashed 1.7 again, disabled automatic restore apps while synching with google. I used the battery calibration app from the market this morning and have set custom battery management to turn data off every 15 mins of non use. This is practical since the power boost script shortens the time to speed up, so data on/off shouldn't affect performance. I'll update at the end of the work day. Currently at:
85%
1Hr 21mins
Maps 43% consumption (I'm adding GPS on all day in addition to blue tooth all day)
Cell idle 19%
Blue tooth 18%
Phone idle 14%

By your justification you are not getting normal/average battery life.
You are disabling data and your cellphone when not in use just to get close to average.
My battery drain has been pretty bad.
I have done all required steps (multiple times) but it still seems like the phone is just flushing the battery out of it.
The best life i have gotten is when (the other day) I was working from home and completely forgot about my phone.
I left it unplugged and after about 8 hours (of literally ZERO use no WIFI) the battery was at around 36%
Its like its pumping it out at full blast no matter what.
Note: I have all powerboost mods installed.

I just flashed back to stock, have the same apps and still getting the same battery life. I am actually getting more network disconnects for some reason, however common sense says that has nothing to do with stock rom or DT rom. Its a driver issue that will be getting resolved in Nov (hopefully) . Flashing back to my sexy DT rom tonight, with a full wipe.

I don't really understand what people are trying to solve.
Your problem is you left your phone on performance mode and it drained your battery. That's like leaving you car lights on and expecting it not to drain the battery. I'm exhibiting extreme heavy usage vs normal practical usage and how the ROM does *not* affect it negatively relative to your daily usage of the phone.
In my normal day, I would not have bluetooth running all day, which from my above data consistently drains 30% of the battery. Bluetooth is only used when I'm in my car which it connects to the car audio for phone and music. In my normal work day, I would not have GPS running all day, which from my recent post is draining 43% of the battery. In a normal week, I would only need to use GPS to find a unique restaurant that maybe I haven't been to or in an area I am not familiar. The main point for the contribution in this "battery investigation" is that I am not experiencing any radio loss, connection failure, or system lag by having Data shut off.
I really do not see the occassion that anyone would ever use their phone heavily for 20+ hours straight. Or even more than a movie's length straight. I could think of possible arguement points such as hiking and needing it to last for saftey/emergencies -- but why would you have it full blast on performance? Long car rides -- but if you are doing an 8+ hour drive, don't you plan on having a car charger? I just don't get what people's frustrations are. I do understand the problem that people's battery tick abnormally which is a fault of either the device, a defective battery, or lack of following directions when using the ROM. Again, the ROM is a development, and no one is forcing you to use it. It is actually quite nice to test, run into a problem, report it and have it fixed within days/weeks instead of months or never like the stock.
I guess I've rambled into a rant, but I'm merely providing my own experience in details so that people have a general feel of how the battery is and if my usage is similar to theirs.
I'm not claiming to have average/above average battery life, I'm justifying that this has not affected my daily use of the phone for everything that I use it for (being connected to work, being socially connected, and games/movies/music).

Battery Life

I can't believe how incredible the battery life is on my Sprint Note 4. To give you a real world example of what I'm talking about...I'm a ups guy and stream Sirius over my phone to my wireless boombox all day while I'm delivering. My previous android phone on a full charge would get me to about 1PM before needing to charge the phone from this streaming.
With my Note 4 today I started streaming sirius at about 8:30am this morning and streamed it non stop all day for 10 hours. While streaming I also browsed the internet on lunch for about 40 minutes of screen on time for that. I then made about 40 minutes of phone calls after work on the way home. After all of that...I still have 60% battery life left without any charging today.
Man I love this phone!

tried ultra battery saver mode for the first few days and made it from 100% to 25% in 2 days and 4 hours with ultra on and off. then played a game for about 7 hours and it drained my battery 50%. Damn impressive

Not sure what to make of mine, I lost 10% in an hour, most of that was when I was driving!
Hmmm, but then I do seem to have a lag issue like others seem to be having too?

It's either something you have installed or how you have your preferences set. I turn off wifi & gps except when I'm using them (both for battery and privacy purposes).

Reloead some screenshots of the battery for more info and in better quality because I can't see this one.

I simply can't agree more dude the batt life on this beast is simply incredible I'm averaging around 13-15hours off charge with 6-7hours On Screen, take note (pun intended ) that when I put it on charge when I go to bed I still have well over 25% battery remaining, its simply incredible, even for us heavy users.

Must have a lemon
I have had my phone for about 3 days and I charge it to 100% before going to bed. When I wake up the battery life has dropped all the way into the 60s. before this phone I had a note 2 and this is way worse than it was. Screen was obviously off all night. Any suggestions appreciated!

It all depends on what you have running in the background. Push notifications? I've frozen all bloatware and turned off push. Is your wifi on maybe? gps? I leave mine unplugged all night (12 hours) and it goes down 3%

Did you install anything special like Greenify? Did you use any of the extra battery saving modes? What is your screen brightness set to?
I think the Sprint version is the Snapdragon, not Exynos, right?

I absolutely loved my Note 2 battery life, but this Note 4 battery life surpasses my Note 2 by a fair margin. I am one happy camper.
Edit: Sprint SD version.

I'm getting less battery life than I expected with my Exynos note 4. I just got out of bed and unplugged it , and used it for about 15 mins to browse tapatalk and email and etc. And in that 15 mins I lost 5% .

I also noticed a high Android System in my usage. Any thoughts on what could be causing this?

This is screen cap.

Mine today

Im only plugging in now at 24% because im going to bed.... actually i have a second battery i might let it run overnight

Pretty good

If you have battery issues, make sure you are not syncing to drop box or google photo back up all times. For example, I use photos to back up all my photos but in the settings I have it only back up when plugged in to the charger. Hopefully this might help someone.

Nothing special installed for battery life and not using the power saving modes. I keep the screen set to auto brightness when at work, but put it on max brightness at home on the weekends when I know I have chargers available because I love the nice bright display. Yes, I have Sprint which has the Snapdragon 805.
I turn off GPS & Wifi when I'm working for battery saving & privacy purposes, but leave bluetooth on all day. I don't have my microsoft email auto synced, but have gmail pushed.
Here are the results from today (attached). Still well over half a battery left after midnight.

To all the people with battery woes-
Pause your pedometer in s health and remove pedometer from lock screen(of course if you don't use it much). It saves a hell lot of battery. It did at least on my SD805 note 4.. I am a heavy user with 3g on all day but never run out of juice. Screen on time averages 7-8 hours daily with browsing/playing games/chatting. I have wifi, synch and gps off when i am not using them.
And yeah i charge every morning, but have never seen my battery less than 39% when i charge lol. This beast is incredible. *super satisfied*

Phone dies at 5%....

So, this is a strange issue. When my phone dies, it will die when it says I have 5% of battery. Sometimes, it will die at a reported 4% instead. This randomly started one day. I got the 5% remaining notification, and suddenly, my phone shut down. Ever since, I can't get below 4%. I've tried to turn the phone on, but it acts like it is dead.
I'm not sure if it's just reporting the wrong percentage, or if it's actually dying early. I've tried flashing different ROMs, wiping everything, and no change. I've also used Battery Calibration to delete battery stats, with no change. I've had issues with other phones dying a little early, but battery calibration always fixed it, so I'm at a loss. Has anyone else experienced this? Is there anything I can try to fix it?

Definitely have this issue too. Dies at 4% strangely enough. Thought it suppose to croak at 0% lol.

Its just not reporting the percentage properly. MIne does it too.

The phone will shut off when the *voltage* drops below a certain threshold, regardless of what the actual "percent left" indicates.

Yep indeed.
There used to be tricks to get the % to show correctly but they weren't entirely good.

In theory, the percentage display is supposed to calibrate automatically to the voltages... however it should be noted that the battery's *minimum* voltage does need to be programmed in at some point in the process, since the shutoff voltage can NEVER vary. Most likely, the problem of shutting off at 4-5% is a matter of "feel good" battery levels, much like some lingerie stores will label items with the "next size down" or "next cupsize up" to make women feel smaller and bigger in the areas they want. It basically bumps the full scale percentage display by an average of 2.5% UP, which can lead some less observant users to viewing that as a slightly improved battery life. Most people will plug in before it hits 5%, so won't even notice this.

So, basically, that's just how it is? I've never had a phone that was so off. And I still don't understand why it went down to 0% or 1% the first few weeks I had it. It's not an issue, it's just strange.

mine shuts down at 3% every time

my nexus 5 died after going to below 1%. every time. i have a hard time believing thats just how it is in this case. chalk it up to yet another lollipop bug i would say...

My n5 shuts down at 1% every time on lollipop. Chalk it up as an n6 "bug" if there's chalking to be done.

I also have this issue and posted a similar thread about it a couple weeks ago. Given that any other device I've owned has been able to consistently reach 1% before shutting off, I think this is either a Lollipop bug or specific to Zthe Nexus 6.
I'm going to test it with my Nexus 9 and ask a buddy about his Moto X 2014 and report back.

Mine died at 9% sigh...

I remember having used that app to try to squeeze more life out of my Galaxy Nexus back in the day. It hasn't been updated since 2011...

That's the funny thing though, because it never did that. It just aligned shut off with 0%

Happened to me once so far, hit 4% and it shut down unexpectedly. I chalked it up to the kernel at the time, as I had flashed a new one the night before.

Maybe it's intentional?
The Nexus 4 could sometimes be a real pain to reboot if you let it go completely dead. I suppose it's possible Motorola/Google are preventing complete depletion of the battery.

Complete depletion of the battery would literally lead to an explosion upon recharge. That's why all lithium based batteries have an additional 10 - 20% below the battery chip shutdown voltage.
Also a phone that shuts down at 5% is more likely to automatically shut down than one that shuts down at 0% as its a little more unpredictable.

now i have the opposite problem. my phone keeps charging after it hits 100%. i use current widget, and watch it when im charging. and current keeps coming in after its at 100%. it will depend, but sometimes it could still be charging for a half an hour after it hits 100%. but then again, it could stay at 100% for 30-60 minutes after i start using the phone on battery again :silly:

I remember the battery calibration trick on Tue original HTC desire. Turn the phone off and charge to 100 then reboot and charge again. It got the % out of whack and gave a false perception that the battery lasted longer as it stayed at 100 for much longer than it should do.
