Evo Battery with 1.47 OTA Massive FAIL!

Since applying the 1.47... OTA, I can literally watch the battery drop minute by minute while the phoe is active.
Within the first 1 minute of removing the phone from the charger the Battery Status Pro reports the charge droping from 100% to 97%. That's a 3% drop in 60 seconds.
Within the first 3 minutes of active use BSP reports the battery drops to 93% charge. That's 7% loss in less than 200 seconds of use.
Now I'm not saying BSP is 100% accuerate but I expect it's not too far off.
Battery life with the Evo has never been phenominal but this seems rather extreem. The drop seems far faster now than when running the 1.32 release. And... while I am in a 4G enabled market, this is with 4G disabled and the phone running purely on 3G with no flickr, twiter, facebook or other feed widgets running and autosync disabled for all of them.
When I look at Battery Use under settings / About Phone / Battery the Android System is by far the largest user of battery, nearly twice the next closest user which is Cell standby.
Am I the only person experiencing this?

The phone was doing this before the 1.47 OTA, it's a problem with charging the battery in the phone. It does not charge properly for some reason and it will drop all the way down into the 80's within an hour of unplugging it. If you get an external battery charger and use it to charge the battery the phone will stay on 100% for an hour or more...

Have you removed the HTC people widget from home screen? The day I removed that was the beginning of decent battery life. Also try turning off the phone when charging - seems to work better that way.

I would try charging to 100%, unplug, wipe the battery, plug it back in again until the light turns green and try again and report back.

I wondered if it was the powered off portion of that battery trick that was doing it. Hmmm. I'll have to watch. Is there any link/source on the idea that the phone itself is not working so well at charging?
Out of that voodoo on the getting better battery life the only thing I could come up with was...-charges better when off, - you need to charge for a bit while on to reset the battery indicator, - and charge a bit while off to top it up.
So I was leaning toward it being a charging thing and not a battery thing...would like to see any technicals though and not just my guessing.

People widget has been long gone.
I gave the charge it with the phone powered off thing a try. The device was down around 80% charged when I powered it off and plugged it in. In about 5 minutes the charge indicator turned from amber to green as if it were fully charged.
I can't believe that the battery charged 20% in 5 minutes.
This leads me to believe that the first response is correct. The battery simply isn't charging fully in the phone. I believe I'll look for an external battery charger and give it a try. See if it makes a difference.

Seriously, try full-charge, wiping your battery data and then shutting it off and 'topping it off' and reevaluate the situation.
EDIT: The "topping it off" thing is all voo-doo as far as I'm concerned. I just do it to be safe, though I'm pretty sure it's ineffective.
I screw with my phone so much, so much flashing/restoring back and forth while on charge, between
charge, car charger, USB charge at work, wall charge, flashing again, kernel swap, restore back again...etc etc etc...that if I don't wipe my battery once I hit a full charge there is no way I can trust that meter to do anything more than change colors. I do it every few days when I notice the meter isn't being trustworthy.
If this doesn't work for you I'd say you probably have a bunk cell in your battery, and failing that your phone just might not be charging well.
Also, charge with the wall and not USB. USB takes forever. And 20% in 5 minutes isn't TOO far off if you are plugged into the wall and getting full-power charge. Maybe 10-12ish minutes, unless you were timing it very specifically....

I just got my bricked replacement. Here is the data from a 100% charged battery usage up time 18:13 .. Awake time 15:27 the battery is at 87%

funny im getting 20 + hours a charge after the OTA
with heavy usage

Broken battery?

Hi!
I'm suffering from a strange battery behavior lately: This morning, after 9 hours charging, I woke up to a 75% full battery, when usually, it should get 100% charge overnight. Previously, I had an accidental power off by power depletion, some hours ago.
Now, I'm trying to charge the phone but it seems to charge way too slow.
Finally, I decided to power it off and let it charge without any possible drainage. In the moment I powered it off, I was prompted with the battery icon displaying 96% charged...??!?!?!?
I don't know if either the battery is broken, the rom is reporting it wrong or what.
I usually play Ingress, which drains the battery like crazy, and I'm usually browsing the internet and reading twitter on my phone, so, at the beginning I thought I just needed to keep my hands off the phone for a while and let it charge, but after that overnigt 75% charge incident... I don't know what to think.
ROM is Carbon ROM KK, kernel is AK without any tweaks, no undervolting or anything... any advice?

Don't over charge.

Yes, I have the bad habit of being unable to see my phone drop the battery level under 60%. At my job, I always leave it on a qi charger, regardless of it being full or empty. Perhaps I have to take the habit of letting it drain until 30% or so, and start charging then.
Other thing I can do is limit the charge level top, tweaking the kernel setting via synapse..... Could that be a good thing?
After starting the phone, the battery level seems to be OK. It's 87% now and it's draining quite slow, compared to before. I guess I'll have to start treating my battery better.

Some update: the phone was bought on March 2013,but the battery has a build date of December 2013. I think the guys that repaired the phone swapped the battery for another one and left me with a defective one.

[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...

Crazy Battery Status

Hi, I'm having a weird problem. Last week I replaced my phone's battery. Everything was going fine till the first charge. The battery percentage isn't showing the right value.
After charging the device all night turned off. Battery shows only 79% of charge. If I let the phone charging turned on, it gets to 100%, but short after drops to 85% and then 79%.
First I thought it was a faulty battery. But I'm using it for a week now, and the device holds a day without a charge, I can even get 3 hours of sot.
I tried fully cicles of charge, to see if it's some kind of calibration, but nothing helps.
Any ideas?

Calibration apps or BBS?

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.
