Hello, a couple of months ago my battery started dying on me so I went to Samsung to get a replacement (my tablet is still within warranty). Despite the fact that my Knox counter is triggered they've changed my battery as well as my tablet's motherboard (don't know why). In the first few weeks I would get quite good battery 7-8 hours of Screen on Time, so far so good.
In the last month or so -though- I'm starting getting quite worse results. The battery leak while sleeping is 2% every 8 hours, so I'm great there too (amplify + greenify work miracles), so the only thing that I can think is that the battery has started dying again (already?). I've let my tablet reach 0% and shut down on its own. Then I booted into recovery and let my tablet on with full brightness for another hour until it was finally off. That's *one hour on* with full brightness!
It seems obvious to me that that's a calibration issue. I deep cycled my battery (twice!), but the results persist (battery is 0% after 5.30 hours of SoT, an additional hour of full brightness is needed until my battery is really depleted). I've made the calculations and found out that if I could actually use that extra hour of full brightness, I would still get 7-8 hours of SoT.
What happened? Why is my battery suddenly got itself "decalibrated" and why does deep cycling (or deleting the battery starts) never works? I think that I should get my tablet back to Samsung again (it's still within warranty), but I would prefer not to as it'll take another 2-3 weeks (again!) to fix it and I'd much prefer to have my tablet in the meantime. So do you have any quick and dirty method to get my 2 hours back?
BTW I know that 2 hours less of screen time , sounds little. But it's exactly the amount of time that deems whether I should charge my battery twice or once every day (yeah I use my tablet *that* much, as it also doubles as my laptop on the go)

I've had the phone since Sept 6th and this is 4th day I have my phone.
My battery life has been draining like crazy. I don't have a data plan, but I do go on wifi sometimes (not very often, and I don't keep it on for long). Maybe in total an hour to two a day.
I wouldn't say I am a heavy user, I don't play any games or watch any videos nor listen to music at all. I only sms and download apps.
It's been 5h 42m 35s since unplugged and my battery life is down to 57. I hardly use it, my settings are pretty much the lowest.
It says
Android System 40%
Cell standby 21%
Phone idle 13%
Display 12% (weird, since I have animations are turned off and I used lowest brightness)
Camera 6% (I took 3 photos)
Wifi 4%
Maps 2%
Dialer 2%
about 2 hours ago, I rooted my desire since I've read reviews that it makes it faster, prolongs battery life and what not. (plus I could do so much more with it later on). But my battery was still draining at like 1% every minute and half that I touch it. (I also have task killer, but I don't kill task very often)
Then my friend suggested I get SetCPU (which I did) around 2 hours ago after I rooted my phone. Then I went out and hardly touched the phone unless I received sms, or to check the time. And it went from like 69 to 56 (within that 2 hours of doing nothing)
I've searched the forum for extending battery life (and googled as well) and read other users who have the same problem, and I pretty much did what was recommended but it's still draining.
I can hardly make it through the day!!
Is there any other way that I can charge it (when to charge it) or.. do you think it might be my battery's problem? Should I buy a new one?
Thanks for all the help again (I know this kind of thread has already been done, but that was in like April)
Your battery takes time to settle if it's a brand new device. It takes a few charge/discharge cycles for that.
If after say 14 days you are still getting poor life I'd try calibrating it. Instructions are HERE.
thanks! i will try that if my battery life still drains this crazily in a week.
Bit of a preamble...
Because I'm a stickler, I spent a while getting used to my device when it was stock and eventually with medium to heavy use I was getting 36+ hours out of the battery. It nearly always hit 1d 12h before I even considered recharging.
I then went with Gingerburst and was delighted to see that the battery life remained the same. Now, Gingerburst wasn't happy with my class 2 SD card and Sense restarted all over the place, before eventually crashing in such a way that I had no choice but to wipe it to get functionality back. I fancied a change anyway, so flashed Miui to my phone.
At this point, battery life went to the knackers...first run through on Miui was a mere 10 hour battery life. I stuck with it for a few days but it didn't improve, and a couple of other things irritated me as well. (Another story)
I've since gone to Ginger Villain, and although the battery life is a bit more than 10 hours - more like 18 - it's still nowhere near what it was. For example, it's on next to me. Wireless data turned off, just mobile signal and wifi for the last 15 minutes, and it's shed 7% in an hour and a half. By that reckoning I'll get 20 hours out of it.
Looking at the battery usage curve - on stock and Gingerburst, it'd barely decrease, being more or less a horizontal line, unless I started doing things, whereby it'd steepen. It seems like since flashing, it follows a steady decrease at a steady rate whether I'm doing something or not.
I've recharged to full and wiped my stats to recalibrate but so far, very little change.
Any ideas what's caused this, or how I could fix it? It's very frustrating to have to charge it so often again!
(P.S. Oh, and another reason I'm irritated enough to post - it went flat from 39% overnight. Whilst on airplane mode. Which meant my alarm didn't go off! When on airplane mode before this started, it wouldn't shed a single percent point overnight!)
Ok so after a hard reset and at 100% charge my HTC Radar says 1 day and 15 hours remaining. It has been like that for a few days. After about a week, 100% charge results in 20 hours remaining life. Eventually after a few more charges it averages at 15-17 hours remaining battery life. That is a big worrying decrease. These figures are always noted after a 100% charge and leaving it to settle for a bit.
So I started thinking what could be causing this decreasing stand by time?
Two theories:
1. It must be an app as I got excellent stand by time from a hard reset and with no additional apps so maybe a particular app is playing with the battery meter?
2. Could it be leaving the phone over night plugged in is doing something to the battery? Maybe I should unplug it as soon as it gets to 100%?
The strange thing is it can't be the actually battery degrading over time as the phone is new. Also, I have recently flashed a custom ROM to my Radar at a point when stand by time was at 15 hours at 100% and after the flashed ROM the standby time went back up to 1 day and 15 hours. Something is not right. It must be an app.
Any other thoughts/theories or anyone else in a similar situation?
Discuss please so we can all learn something to hopefully solve this problem for other handsets too!
My guess: calibration. The system estimates your runtime based on previous runtimes, that's why it's getting lower. Did your phone actually ever run that long, btw?
yes it did. very very close. i was amazed.
and does it now actually run out faster? I have noticed this on my ipod. It used to tell me 1h battery remaining and it would run for another 3h until i got home and another 2h the next day (when I noticed I forgot to charge). Also, are you using your phone more now? The biggest battery drain is the display.
Remaining battery life is estimated as follows:
Immediately after being removed from the charger is based on previous usage charging.
After this time estimate is based on current consumption.
In the first week after hard reset or install ROM the period are recorded in the system.
After a year of use of personal phone (HD7) and trying different rom and different settings for gps, 3g, edge, and light i found that the consumer eating large battery . After a more detailed study will say that is the main consumer.
Thanks for your comment Ovi but this is not about how the consumer is wasting the battery by usage. The question I raised was about how the standby time varied at 100% after a hard reset and after weeks of usage at 100%. The stand by time decreased without using the phone after a full charge. That is what is puzzling me. In theory it should be the same stand by time no matter how long the phone has been owned and the rate of discharge is due to usage - agreed.
Hi guys. Im new here. I just wanna share about my Z1 compact latest battery problem kinda frustrated me lately.
I bought the phone 2-3 months ago, already with Android Lollipop 5.0.2. Since the purchase, I didnt really face a problem with the battery life as it lasted about 12 hours per charge due to my heavy usage of the phone.
But a few days lately, my phone being worrying me as the battery doesnt being as normal as always. For example, it can drain the battery drastically from 88% to 67% in a few seconds when the screen is off (in standby mode). Sometimes, in the middle of the usagefrom 39%, the phone suddenly shows the battery low warning with a 1% battery remaining, and without having enough time to reach the charger, it shuts down by itself.
In rare cases, I caught my phone drained the battery drastically when the screen is still on from 15% to 1% less in a minute.
The phone wasnt rooted and I didnt anything else besides my daily normal usage. The latest apps I downloaded before the problem occurred is Waze.
I tried everything to save the battery like using the Stamina Mode, force stops some apps, slides away all of the running apps in the background but failed. I even factory reset my phone and installed all the apps the way it used to be but still didnt solved the problem.
I still have about 8 monts of Sony warranty but I need you guys help first because I need to use my phone for work right now. Please help and reply.
Thank you. *Sorry if my English isnt that good*
When the battery jumps from 39% to 1%... Does it stay a long time at 39%? Or from 39 to 1 in few minutes?
Just curious...
Sounds like a warranty issue to me. You could try to find out what is causing heavy drain like with BetterBatteryStats. But no app ever should cause such drains.
Sound more like your battery is not okay.

The exactly same problem with me .I have 100% battery and indicator stays 100% for a half hour than drastically drains to 1% and shuts down.
Change your battery! I had the same Problem. I changed my battery with anotherone original from Sony, but a few weeks later the same Problem: quickly battery drain.
So I ordered me a battery from e-bay but NOT one from Sony! Now a few weeks later still NO Problems. Everything runs Ok now. NO battery drain at all.
hi, all i need to know is that this is normal, and ill forget it. i bought a hyperion battery and it kept rebooting my phone which i know like the zero lemon has been a problem. i was getting about 10 hours with that battery so i put back in the stock battery (2 months old) and it goes from 100 to 6 percent in six hours. That's with two phone calls five min each, no gps no Bluetooth no wifi and the screen at 50 percent and the time out at 15 seconds. i close programs all the time.. i have the battery doctor and all of that that tells me when programs are draining, but noting is helping. Is six hours what i should be getting from this battery with light use? i watch you tube videos of guys who get 25 hours but i know thats not the norm. thanks if any one has any feedback on this.

have you tried a factory reset? i know that has solved other peoples' battery problems
No, this is not normal at all. Either a misbehaving app or battery problems. You can try factory reset and see how much it drains with stock, or you can look for wake locks to see if it's an app before you try get ing a new battery
I'm on the Note 5 ROM and have a zero lemon battery. If I have cell on, I get about 7hrs. I can stretch that out to 10-ish if I keep going in and out of ultra-power save mode. The stock battery (of which I have 3) lasts me 2.5hrs. This is regardless of what ROM I have. Seems when I have cell turned on, the battery dies very quickly.
