[Q] Epic Battery Life Test - Epic 4G General

All,
Please try this before complaining about battery.
Go to:
Settings then to privacy then do a Factory Data Reset.
You will lose all your user installed apps.
What ive noticed on day 1 Battery showed full charge. After a factory data reset the battery meter dropped to almost empty
full charge overnight and i went all day and night after using pandora, making 3 hours worth of calls, using the web, check checking work and gmail email, sending texts and a few other thing.
With my evo i would have had to charge it after about 6 hours. PLease try the above and post your results.

Nice find dude. I just tried it out on my phone and while it may be a bit preliminary it seems to of fixed my issues. Before I had only been able to charge my phone to 100% TWICE. All the other times it would hit 95-97% and tell me its fully charged and would not go any further, i would turn off my phone and plug it back in and it would charge a little more, but as soon as i unplugged my phone and booted back up it would be at 95% and fall very quickly. This morning it had only been unplugged for 1 hour and 20 minutes after being plugged in all night and it went down to 65% I plugged it back in and let it charge, it was at 95% and still charging when i saw your post and decided WTH and gave it a try.
While it was still plugged in i did a factory reset and it erased everything and when it booted back up it said my phone was at 100% but the charging light was still red. I let it keep charging, even turned it off and it was still charging, it charged for probably another half hour before the light turned blue, i unplugged it and turned it on and it was still at 100% I used my phone sending texts and reinstalling all my apps and setting them up and its been probably half an hour and its at 98% as i type this So things are looking up I never even saw 98% before haha, the two times it DID charge to 100% it literally jumped from 96% straight to 100%, then fell to 95% once unplugged.

Just out of curiosity what do you guys use to check your battery percentages? (i'm new to android having come from the iphone 3g)

I've been using Battery Indicator, I really like it.
h**p://www.androlib.com/android.application.com-darshancomputing-batteryindicator-xxti.aspx
Also, from what I've been reading so far, most of the issues are app related and a few defective batteries.

Tried this and didn't seem to work, the display is still hogging 70%+

Battery ran down in standby

I left my nexus one, which I just got on Friday, next to the TV and it was fully charged. When I came back to it about 4 hours later it had turned its self off and wouldn't turn on until I connected the charger. The battery was at 0%, anyone seen anything similar?
I have now left the phone off, connected to an AC charger and will turn it back on only when it's fully charged!
Sounds like you got yourself a defective unit.
Charger it fully then let it completely die. After it dies charge it again fully see if that helps.
Charging via the USB cable does not seem to be very efficient/reliable. Using the AC charger is quite fast, and much more reliable.
Also check the apps that are running in the background, and turn off the ones you don't need. I discovered that the animated wallpaper was quite a drain... since I switched to a static wallpaper image, battery life has improved significantly.
It has the star field wall paper, but I didn't think that would run when the phone is locked and the screen was blanked. I'll leave it to fully charge, using an old nokia charger from a n85.
So the recommendation is to run it tomorrow until it dies then charge in the off state and only turn on when it's fully charged?
I have had a G1 for the last year.

I have the same problem. I got the phone approx. 1 week ago. before i go to work, I would have a fully charged phone. during lunch break break, ( about 4 hrs later from fully charged) its below half already! then 2 hrs later, its at to the point where it says connect your charger. Finally, off work, Phone is turned off and dead at 0% battery life. When im working, i dont even use the phone to browse or anything. just check the time on it and put it back on standby. I dont know whats wrong. Ive also rooted the phone btw with MoDaCo's rom. Any suggestions?
It was fulling charged again about 3 hours ago, not I've left it without wi-fi and with a static wallpaper and the battery is still full. I wonder if the wi-fi or the live wallpapers keep running even when the screen is off. I have checked and wi-fi is set to sleep when screen is off :-/
While modern batteries don't have the "memory" problems that cause them to lose life, they can suffer from miscalibration which will cause them to inaccurately report their remaining charge. If they report a very low charge to the phone (when this may not necessarily be true) the phone will probably turn itself off.
To recalibrate your battery, force it to drain completely. Even after the phone turns itself off, turn it on a few times more. I can't guarantee this is good for your phone, but it should get the last of the juice out. Then, when you let it charge, let it charge LONG after it reports being full, at least a few hours, to make sure it's completely full.
Sounds like something isn't quite right with your phone tbh. I have the star field wallpaper, wifi on and it's checking e-mails for 2 accounts every 15 mins.
I've also had some phone calls, been surfing the web, market and generally played around with it since I just got it on friday.
I checked the battery info on the phone now and it's been 15 hours since I charged it and it's now on 46% still. In my (limited) experience the battery seems to hold up pretty good on this phone.
That's the weird thing, it was fine Friday night and Saturday night and that was including quite a bit of playing with around
I received my phone last week. the battery was fine the first four days. after that the same problem stated above happened to me. the battery dies every 4 or 5 hours even in standby with no GPRS, WIFI or BT.
I did a complete wipe-out and the problem was gone.
I think that there were something that is draining the battery and gone with the wipeout.
by the way, i was using MCR and still using it.
thanks.
It has now been sitting for another 7 hours without wi-fi or starfield and the battery is still showing full. I'll now enable wi-fi and see how that goes. Then I'll try statfield later on. I'm wondering if the starfield keeps running even if the screen is blanked.
Actually it's showing 92% in the About page whereas the icon look full :-/
First day with nexus at work. Unplugged it from the main charge at 6:30 am at till 1:00 pm its was turned off. Made 3 short calls, no wifi, bluetooth, or gps and screen set to auto dim.
Only 6 1/2 hours is not long enough. I wish there was like a juice pack for nexus like the iphone. I could buy another battery but cannot be bothered carrying too many bits with me and opening it and changing.
Aslo charging through usb is very very slow.
my phone did this yesterday too, first time ever. I dunno why it drained so fast, something must have kept the screen on in my pocket or something.
Here's what I found.
I got my phone friday, took it off the charger and went to bed. When I woke it up was dead. What I do know is that since I'm with Roger's in Canada I don't get the 3G. I think it was searching for a 3G signal all night and that's what killed it. Try limiting it to 2G and see how the battery stands. I went a full two days without a charge, playing with it every chance I got and wifi turned on.
I'll try the 3g thing as the phone reception is poor in the room I left it. It is at 79% with the star fields wallpaper and wi-fi enabled (sleeps when screen off)

The star field wallpaper KILLS my battery even when the phone is idle with the screen off, just FYI... I switched to a default regular wallpaper and it has been fine since.

thanks i will try 2g setting tomorrow.
There gotta be something wrong with your phones or some software that is draining it.
Like I said on the previous page I use:
WiFi on
Star Field live wallpaper, with the background image nontheless
Some GPS use
Several phone calls
Some texting
Browsing the web
Screen brightness at maximum
2 email accounts updating every 15 mins
My battery still lives through the day with ease and I'm usually at 40% when I go to bed at around 1 am. I would call HTC or do a thorough check at what software is running.
edit:
Oh and I have 3G on with low reception (1 bar) where I live.

Charging with screen on - charges Evo better?

Yes, I know. We're all sick of these battery threads. But I just came across something I wanted to share with you all.
Before I continue: I don't use any task killers. And I've read every battery trick thread on here and on Android Forums, so I've done it all. The CDMA fix. Rooting and using OCWidget. Charging it to 100%, turning it off, and then cycling the charge with the phone in the off state. And of course, disabling every data hungry app plus setting screen brightness to 50%. This is my 3rd Android phone, so it's definitely not my first rodeo.
So last night I was using my Evo as it was on the charger. I was browsing the web, and checking out some new apps in the market, so the screen was on for quite a while. I took my Evo off the charger, did some heavy texting, some browsing, Facebook, Twitter, etc, etc, and about 5 hours later I was at 80%. I then put it on the charger, and went to bed.
Fast forward to this morning: Took it off the charger, sent a few texts, and I'm down to 95% within minutes. Of course this frustrated me, since last night I went an hour before it even dropped to 99%. It'll be getting some heavy use today, so the last thing I want to do is leave the house with my battery in the 80% range. I put it back on the charger, and resumed normal usage. Some texting, Facebook, Movies app, Netflix app. Eventually the charging light goes green again. Took it off the charger an hour ago, did some texting, stayed connected to WiFi,and I'm still at 100%. Whereas earlier this morning it dropped 5% in minutes under the same use.
Scratched my head for a second, and remembered that my phone was on and in use while charging last time, before I took it off and got great battery life.
So now, I've set it so my Evo's screen stays on while charging. I also use the Power Control widget to increase the screen brightness to 100% while charging. And then once it's off the charger, just drop it to 50%.
To keep the phone awake while charging:
Menu -> Settings -> Applications -> Development -> And then tap the check box next to 'Stay awake'.
Not saying this is guaranteed to work, and I have no rational explanation as to how this works, but it's definitely helping me. I'm going to do some testing and report back on a few things.
I think you might be on to something. I recently had an experience where my batter was around the 60% mark, I plugged it into my computer for about 30mins - 1hr and somehow it managed to charge to 100% battery in that short time span. Needless to say, the battery drained pretty quickly until it reached some stable point. I'll try the charge with screen on thing when I get a chance.
as odd as this sounds, i have notice the same thing when using my phone while on the charger then taking it off. I use screen cast when i'm at work, so my phone is always plugged into the computer. Once i leave work for the day my phone is usually fully charged or about 80% with moderate usage my phone is usually around 60-70% when i lay down to go to bed. Now on the weekened when i charge my phone overnight, the following day with moderate to heavy usage my battery drops to like 50% within a hour to a hour in a half. So i plug it in while texting or browsing, and when it get fully charged the battery seems to take 3-4 hours to get to 50% with moderate to light use. Weird
I've currently enabled every bell and whistle on my Evo so I can speed up the battery drain. I'm making note of the voltage reading at each percentage (via Battery Indicator), and then I'm going to charge it back up with the screen off to compare these numbers.
I think the issue isn't the charging with the screen on. I think there may be a "bug" that, when the phone hits full charge, it doesn't continue to charge but instead starts using the phone battery. Thus, when you charge at night, it's fully charged for a while, you start using it in the morning and it quickly drops to whatever has already been used (~94-95%). But, if you charge it and take it off soon after the light turns green, then it's fully charged and you're getting the full 100%.
I think there's a problem with the trickle charging.

My testing confirms this theory. I put mine on the charger after work, and the light was green when I went to bed.. the next morning when I unplugged it, it dropped to 90% within a few minutes. Everytime I've unplugged it right after the green light comes on, it stays on 100% for at least 15-20 minutes of use.

That explanation sounds accurate, so instead of doing all this it might b a simple tweak to not have this trinkle effect happen

It was mentioned in another thread that "trickle charge" gives the battery a better deeper charge. Perhaps a 500 or 700 mah charger will do the trick instead of risking a screen burn.

[Q] Nexus 10 Battery Calibration Off

I have this strange issue with the battery calibration.
At first i thought the battery was dying on me. It normally stay active to 35-44% and then the OS would just suddenly report the battery is dead and just turns off.
Then i just boot into TWRP recovery and leave the screen on. And it's able to stay on for another whole hour at maximum screen brightness till it actually dies.
I tried deleting the battery stats in the data folder and letting it drain to 0%. But the OS still thinks it's out of juice around 35-44%...despite the fact that it can stay on for another hour or so in TWRP recovery.
Is there anyway to adjust the capacity of the battery in the OS?
Hi,
When this happened to me (but with 20%), all I did was letting the battery drain and charge it fully while turned off. Don't know if it actually works, but it solved my issue. Give it a try .
Good luck,
~Lord

Funny, I had just about the opposite problem. It was stuck at 35-45% while charging, or it would only go up about 1% every 20-30 minutes. Sloooowwww. Same solution seemed to fix it--let it drain to shut-down, recharge with power off to 100%. It seems to charge faster with power off, but I haven't done an a-b test to verify.
So I just started getting this after the update to 5.0 on my N10.
Beforehand I never noticed anything, although its been a few months since i have used it till a really low battery.
But I updated to 5.0. Used it for a while, the OS registered like 70% battery and then instantly 0% and it shut down. So I booted to the bootloader to see and it ran just fine for a while. I got bored and booted it back up, immediately shut down.
I plugged it in and booted it up and it was a 0% for a LONG time before it ever registered as actually charging. Then it charged normally until it got to like 25% and then instantly to 100%.
Im hoping its just a calibration thing, I did a factory reset just to be safe but it still did it. I guess the next steps if it still does it after a few cycles is to install a custom recovery and clear stats.
Same thing here
I've got almost the identical issue as the OP. Tablet shuts off without warning around 35-40% batter. When I reboot it says 0% battery and immediatley shuts down. If I boot into recovery mode though it will stay on for 2-3 hours before dying. I tried this and then charged it to full overnight with the device powered down and still today it shutdown again around 40% battery. Tried a battery calibration app before too but nothing has fixed it. This is 4.4.4 stock rooted with xposed. Been happening for about 2-3 weeks now. I'm pretty sure it's got to be software related right?? Anyone find a fix yet?
Just posting to say I'm seeing the exact same thing. It also just started happening since the update to Lollipop. It is shutting down at about 30-40%, then when I turn it back on it is at 0% and will shut down immediately unless it's plugged in. However, like the rest of you also said, in safe mode it'll stay on for a while longer without being plugged in. We really need a way to calibrate the battery somehow. This is a very frustrating problem. No warning at all!
I also have this problem.....this updates are so bugged.....

I have the exact same issue
After a full charge it's saying I only have three hours left on the battery. Battery life is really poor. I'm not sure if the battery is worn out (I've had the tablet since it came out) or if it's from the update.
Same same.
Just had the same start yesterday. Was charged to 100% ran a high intenssity game for an hour (makes my cell phone heat up and kills the battery like mad) but it was NOT affecting the 100% charge. I thought 'thats funny' then it started to go down some then it hit about 55% then BAM. Drops to zero and shuts off.
After that it would not take a charge no matter what I did but then for no particular reason except I was lazy and didnt wanna have to boot it up again after I plugged it in, I left it plugged in and went to take a nap. Came back an hour later and it had charged to 43% after having been at zero for about 20 minutes after I left the room.
Now its stuck at 43% and wont charge any higher. I'm leaving it alone for a few hours to see if it will ever get to 100% then ill run it down to zero then charge it over night turned off to 100%.
Ive been reading this as a battery calibration problem and came across a HUGE variance on the net about what to do about 'that'.
Some say the charge to 100% drop to 0% charge to 100% will calibrate it. Some say thats old Ni-Cad tech and you shouldnt do that with the Lithium Ions. But then others say you should do it with the Nexus 10 because it DOES calibrate the battery and that the tablet software protects the battery from actually going to zero%. (Saves a few percent and shuts off).
But then also someone else said battery calibration only works via a hardware change inside the tablet and that we are actually talking about conditioning. But then someone said conditioning is the max storage and that the 40% to 0% drop is not conditioning and since the charge discharge charge is for conditioning a Ni-Cad it wont help. Around we go.
There was also mention of a samsung PHONE having a problem with a bent usb pin inside the phone. But you had to pop the battery to bend the pin and since you cant do that a on Nexus 10 that doesnt help. (Plus the pin doesnt look bent to me even though about 30 people chimed in saying it helped them. But that was all phones.)
And finally. One website says you have to root the nexus 10 and use a batter calibratino app to calibrate it as option a but option b was some crazy combination of charge to 100 discharge for an hour, charge to 100, discharge for an hour, charge to 100, discharge till your aunts pink underwear falls off or something equally strange.
I'm betting based on you guys os upgrade bug. Just too strange. My 2 year warrenty ran out last month but I hadnt turned it on in six. Maybe thats a good thing. Be stupid to send it in for repair only to find out it was software.
Have to see if after my full cycle charge-discharge-charge it works again.
Prayin for everyone's devices. This sucks.

Suffice it to say I've been seeing this issue as of Android 4.4.4... NONE of the posted recalibration techniques seem to work and as usual, Google non-support is just as useless. As far as I can tell, once in this state it's here to stay... I've had my N10 shut down at 28%, 37%... even as high as 55%, and on re-charge (if I do it turned on) it charges to a point and then shoots straight up to 100%. I've seen the "takes forever to get above 0%" issue too... none of this has happened in any consistent fashion. I had hoped that friggin lollipop would solve this but instead they added a host of OTHER annoying bugs: as in after I restart it, the tablet goes into an optimization mode where it decides it has to re-optimize all 362 apps I have on the wretched thing. There naturally are a few others but they are beyond the mainstream of this evening's symposium....
Same exact thing is happening to me, but I'm on 4.4.
Same issue for me toosince 5.0 (now 5.1.1 BlissPop)
I'm gonna try to see if after my full cycle charge/discharge/charge it will work again...
Same issue for me too, since 5.0
Same issue for me too, since 5.0
to all of you how had had battery charging problems, please advise y you have used the "magenetic" charging cable. (It charge to a 25% higer rate)
I don't know how... I don't know why... After nearly 10 months of this behavior... I recently went through a couple of charge cycles (after it dropped to zero yet again) without letting it drop to zero.. AND NOW IT'S FINE!!!! I have no clue why... None of the stupid on-line non root solutions worked... I think that it's possible for this thing to recover after a random sequence of events which unfortunately cannot quantify because I had pretty much given up.

I am getting the same experience as most of you. Tablet shuts off at around 45% saying there's zero battery left. I assumed it was the battery going bad.
Sent from my Nexus 10 using Tapatalk
Well technically the battery starts going bad (yeah it's not supposed to... but nothing lasts forever) once you start running the discharge/charge cyle over and over again. To be sure my N10 is more than a few years old and while depending on use it can last a few days... it sure doesn't go quite as long as it did between charges as when it was brand-spanking-new. That said, and as said in my more recent post where I thought that the battery was borked, it now will last around two days with heavy use and about three with moderate use... and it now discharges appropriately to near zero warning me to connect the charger without just dying at 30-50 %... and the charge profile is a smooth curve from low to high with no sudden jog to 100% once the charge indication hits 60-65% like it did before. That would *seem* to indicate to me that this is far more a software issue than a battery one, and that purchasing a new battery may "fix" the problem but it won't FIX the problem! i.e. it'll only be a matter of time before it comes back. For all I know, some recent update to some google app took care of it...
After updating from CM11 to stock 5.1.1 I got the same problem. My N10 switch emmidiatly off at 70% battery. It was fine with CM11. Any news on this? Did a battery calibration, but this didn't helped.
I'm also getting this problem for the first time on the Temasek CM rom from 11/05/2015. It seems to have come up only since the 11/05 version.
Still no solution!?
I am having this issue (I think) since I received the update to Lollipop. So, basically it is a bit more than a year now. I was hoping a Marshmallow update would solve it, but: nope!
For installing Marshmallow I also did factory reset and all that stuff: it does not fix the problem...

Horrible battery life?

I got an S4 i9505 replacement yesterday from my insurance company. It effectively seems to be new phone and battery, anyway when I turned it on it had 70% battery left, I logged into my various things and it sat about downloading and restoring and installing a 5.0.1 update, the process took about 30 mins and at the end of the 30 mins I had 9% battery left, I connected to the charger and it was full again in 30mins which I found odd.
Anyway let it sit on the charger all night, took it off this morning and with 2 mins of screen on time I am already at 94%, I can't see how this thing will last the day.
I am not a newbie, I have things like sync and GPS etc turned off and screen brightness lowered however in saying that even at the lowest setting it seems very bright.
Any ideas?

You cannot jump to conclusions based on this. Your device was setting up, your battery needs to settle etc. It's normal to discharge faster.
Try a few charges / discharges and see if it helps.
But most likely if it's charging way too fast and discharging fast as well, the problem is most likely the battery itself, it might be a old one.
Right ok, been using this for a few days now, with basically everything turned off I am getting 1 hr screen on time, something not right but can't figure out what

Sudden battery issues - stops charging anywhere between 77 and 91, sudden drops

I've owned my Note 4 since October 2014 and it's been working solidly since. Last Thursday, out of nowhere, I noticed that from a 14% charge, it suddenly dropped to 4%. I immediately scrambled for a charger and charged it back up to 100%. On Friday, I charged my battery normally again. Charging finished at 11 AM but the drain was abnormally high. My phone was warm to the touch and battery was dead in 4 hours. I was using the phone normally throughout that time, 4g on, location services/bt off, screen off for the most part. I ran OS monitor to see whether any app was locking up the CPU, but, as expected, the main CPU users were Android System and Android OS.
On Saturday, I charged the phone to full again, disconnected around 4 pm. Being that I was home, both wifi and 4g were off. Battery discharged normally, and was only down to 30% on Monday morning.
On Monday, I noticed that battery dropped from 21% straight to 11% straight to 4% in a few seconds. The drain from 4 to 3 to 2% was decent (few minutes of screen on time, on viber), then the phone shut off. I tried to charge the battery with the device powered off, but noticed that the phone simply stopped charging at 80%. I thought that was an abnormality. I tried wiping the system and app caches, but the problem persisted and drain still felt pretty fast. Tuesday night, the phone stopped charging at 91%, staying at the same level for 40 minutes before I gave up and unplugged.
My friend had purchased a fake OEM Note 4 battery and allowed me to try the drain/charge process using his battery to troubleshoot. When I first plugged his battery into my phone, the drain was high at about 1 percent per minute. When I tried to charge the battery, the charge level would not go beyond 90%. I switched on safe mode, but the battery did not charge any further either. I felt by then that something was definitely wrong with my phone. When I restarted the phone to get out of safe mode, though, it suddenly started charging again and hit 100%. With regular use, the fake battery gave me 16 hours of power, which I thought was relatively decent. Alas, when I started charging it again, it stopped charging at 77%. Battery Monitor Widget showed 0 mA flowing into the phone at the time, though the battery indicator in the status bar showed the lightning bolt.
I took out the fake battery and put in my original. It is now charging up normally, but I expect charging to stop before I hit 100%.
If anyone could provide possible explanations for what could be going on and/or other troubleshooting tips to try, I would really appreciate it. A factory reset would be my last recourse.
Thank you very much!
EDIT: My battery went all the way up to 100% this time. But it's the same one that got stuck (at 80% then at 91%) twice in the past.
I'm using two different Samsung chargers and different cords, by the way, and blew out the port with air prior to attempting to charge the fake battery that still stopped at 77%.
I had the same issue, took it to Samsung and they replaced the battery, it has been okay since that

Really? I was ready to write off my battery and just buy a replacement, but what was weird was that even the newish fake battery wouldn't charge fully. That's what made me worried that it's my phone that's the problem.
It'd be great if this could be as simple as a battery problem.
