[Q] Strange charging patterns

This is how my charge/discharge cycle looks like:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Is this normal? (never mind the discharge rate, I'm talking about the charge).
At about 80% it suddenly jumps to 100%.
Does this mean my battery's not at full capacity, or is it just mis-calibrated?

I have the same effect, only the jump is at 88% while yours is at 81%!!!
Did you notice that the charging process still continues with decreasing current till 0 (after quite long time)

Resurrecting this thread, sorry, didn't notice the reply.
Yes, but I found a way to 'trick' it.
If you see that it jumps from 100 to 80, wait 'till it comes back down to 80 and plug it back in. This time it'll charge until about 90 and jump to 100 again, so again let it drain to 90 and plug back in.
It works quite well, but still as time goes by it seems like my battery capacity is decreasing, which I guess is unavoidable.
The other day it suddenly jumped from 20 to 100, that scared me like hell.

When I first moved to android mine jumped from about 85 to 100, and also went from 10% to dead in one jump. I did a battery calibration and its been fine now for months. I can run it down to 2% without worrying it will shut off.

What did you use for battery calibration?
I tried Battery Widget Pro but it didn't change anything, if anything it keeps getting worse as BWP 'adjusts' its projected battery size.

I ran it down to zero and in magldr(or is it in cwm?magldr I think) chose wipe battery stats, then charged to full and allowed to run all way back to 1% before charging.

I'll give it a try, although I feel as if I've done it already.
Thanks for the tip.

I got the same now on Desire HD (native anroid), it seems normal for phones with old battery

I found the solution is to leave it in the charger until CurrentWidget shows 0mAh. The readings will be the same, but it will actually charge 'normally' though it'll report shorter charging.

Turn off while charging?

I read a blog which suggested, when charging overnight, to turn the N10 off completely rather than just having it sleep. Is there any merit to this? Does it charge faster?

It does charge faster because the device isn't doing anything to drain the battery. Although overnight is often when devices update themselves so it's up to you if it is necessary as it should fully charge overnight.

I dont see a reason to turn off the tablet to charge, and my tablet never gets turned off. Because there was a user here saying we needed to turn off our tablets any time we werent going to use it within the next hour or two, I did some battery tests. This tablet (assuming you aren't running battery draining apps in the background) loses 1% of battery every 7~ days when idle. So thinking the tablet will somehow charge faster while it is off would be false as we really have negligible drain during idle time. That is unless you are syncing a large number of apps and have a ton of things updating in the background.
Currently my tablet has been on and hasnt charged in 16 and a half days. I have been really busy at work during the week and busy with my friends on the weekends, so I have really only used my tablet about an hour and a half during this charge cycle. So have so far lost only 2% battery from idle, and another 19% from the hour to hour and a half from the time I was playing a video game on the tablet. Assuming I dont use the tablet, I truly expect to be able to pick it up in another 2 weeks from now if I wanted and still be in the 70% range on battery life remaining.

And if you do have a lot of stuff syncing in the background, you still wouldn't want to turn the tablet off while charging since then the things you want to sync will need to sync when you're running off battery instead.

Yup, I agree with the posts above. The only way you could really slow down charging significantly would be with daydream running. This display sure drains lots of energy.

I do both, sometimes powered down other times in sleep mode. Don't see a whole lot of difference.

Here are some screenshots of just how long the battery lasts while idle:

Figured I would take these pics now since I will be using the tablet this weekend so I wont be able to show insane idle life anymore

Battery is terrible!

My battery sucks. Even my s3 battery was much better. I get 1% drop like every minute and its not like I use it that much, no games, mosly whatsapp and facebook and all that
I am curently on wanam lite 1.8 wich is supposed to have the best battery and with perseus kernel. I have i9500. Please help me

Post some battery stats...? Or provide some more information of some sort?

14 odd hours is pretty decent battery life? Even with the steep appearing drain. I can only average 10 hours and that's without touching my phone at all. if i moderately use it, it lasts 5 hours tops.
You're probably seeing a steep drain through sync apps, screen brightness, or a combination of a few other small things. If you're that worried about it, download better battery stats and monitor your phone for a few hours to check no apps have gone rogue.

These are my battery stats: Link
Obviously battery analysis is relative to the handset and user, but I honestly think your stats are above average.
Collect a battery stat of one full cycle and compare that, so the charging doesn't skew the results.

@ you dude: it could be yr wifi that causes yr battery to drain, by looking at yr stats.
anyways, get better battery stats like what ChrisRHolstein mentioned to look for the culprits.
and not forgetting, do a 2-3 battery discharge cycles.

Battery wear of your Oneplus one

It's been nearly 27 months of daily and intensive use of my oneplus one and I can't be happier, not even consider buying a new smartphone with the performance of this little one.
I was in fact considering buying a new battery, wasn't noticing any noticeable decrease in battery life but it might just be because of the slowness of the wearing and buying a new one will immediately result in much better results.
I found an app called accubattery that tests wear by measuring charging currents vs charge percentage over time and would love to see how is you battery performing, also wanted to know the results of a new battery if some of you have indeed swapped it already.
Here are some screenshots

}
Considering a new battery would perform about 97/98% (just guessing) that's about 5% wear every 8 months. Seems like a really slow pace if you ask me.
Would love if some of you guys test it for a couple of charges cycles and share your results vs age of your device.

You shouldn't trust these battery apps. Measure it that way - if the battery lasts long enough for you - you don't need to replace it. Otherwise get a replacement and hope that it's better than your current one.
Right now I get about 3.5-4 hours of SOT with Stylo King's profile and I charge it every night. Perhaps I'll replace the battery within a year but who knows - I might just get an external battery instead.

Sure enough, I'm still OK with the battery life. But it's interesting to know how fast batteries are wearing and how much improvement we get with a new one. This app measures how much capacity it can hold, battery life is a different story.
20% wear might not seem a lot but imagine you have an extra 20% each time your battery dies. Might consider a new one in the near future.

i am really interested to this topic too. for now, you can refer to the answer to this thread of mine.
http://forum.xda-developers.com/oneplus-one/general/how-battery-1-2-years-t3414249
the biggest problem at the moment is that most of battery sold online as original are simply fake and works very bad, so finding a replacement it' s hard. Oneplus support asks for aroun 80€ to replace the battery

Battery drain

Can someone explain to me, please, what is going on with my S8. The drain is crazy.

Is that not normal? lol Mine pretty much looks the same. All my apps are at the bottom of the list but iam getting great battery life

what is your SOT?

i get same system usage as you but i 5-6 sot

4-6 SOT, actually, I thought Android battery life has evolved when I bought galaxy s8. But no, it keeps sucking my battery life even when it's in my pocket.

Unfortunately this issue is present on all samsung galaxy phones i've owned recently (s6 edge, s7).
I can't understand why the battery life is so bad and inconsistent.
No matter if all day wifi or mixed (data 4g/lte & wifi)

The background usage is pretty minimal. I don't understand why people complain that "something" however small is going on with the phone when the screen is off. The system is still alive, after all. Notifications need to get through, sensors need to be active to wake the phone (fingerprint, accelerometer, etc), apps need to be kept in memory, not to mention the always on display. Is it that surprising that if battery went down 10 percent during sleep 20, 30 or even 80 of that drop is due to these things? (that's what that reading indicates after all, 9% is not from total battery capacity, but 9% out of the amount drained).
Sorry for the rude rant, but people "expect" too much of the standby times.
Can the battery be improved? Certainly. Can the power drain be improved? Of course. But never to the point where it consumes absolutely nothing at all during sleep. Except if you turn the phone off.

20 hours on battery, 30%left. OP must be trolling.

Normal

I noticed finger print loves to break deep sleep.

4-6 hours of SOT? That's pretty good though... Same with what most people are getting including me. If I drained it all the way down I could probably reach 7 hours SOT. Totally beats the 3 hours SOT I got with my Note 5.

Did your previous phone with a 3000mah battery and a bigass screen get 4-6 hours of sot? I thought so...

Did you realize that when you total up the battery usage, you won't get 100% of battery charge?
