I attached screenshots. Had done a couple cycles from having my device. Battery life is better than normal but, charging is slow and showing jagged lines on graph. Is that normal. I have the same situation with 2 different docks.

I've just upgraded to an HTC Desire after many years with a WM device.
I have noticed something unusual when charging the phone. When the battery reaches 100% it seems to stop charging and the battery starts draining. This means that by the time I wake up the phone has lost between 3 & 10% charge depending on tow early I want to bed.
The green charge full indicator stays on even as the charge drains.
It will not start charging again until unplugged and plugged in again.
Is this an Eco friendly charging feature that yactually stops the charger drawing power?
Has anyone else noticed this?
It is mostly a good thing, the only down side is on heavy usage days my battery just scrapes through 14hrs use and the extra few percent charge helps.

I mist say there are some interesting ideas in those threads. Will see what else is said on the matter.
Can someone explain this? before I went to bed my arc was at 97% battery when I woke up it was 100%?
Cellphone battery meters are not that accurate. That is why on "stock", the manufacturers do not put numbers, just icons. No one has "invented" an accurate meter yet that shows exact percentage left. So don't worry about it too much.
If I am correct your percentage is also calculated by the use of your phone, so kind of like when moving a big file in windows, at the start it says two weeks and after a minuut it says 5 min remaining cause the cpu is less stressed
ive also encountered this kind of issue before because i always look at my battery widget. before i use it i look at the battery it was 30+% and then after playing it came back to 42% it was weird..
I have been noticing something strange. I have gotten in the habit of draining my battery down to single digits before charging in an attempt to keep my battery life up. I usually use netflix on 4g to do this as it does a pretty good job of sucking the juice down quickly.
A few times I have noticed that after I shutdown netflix and let the phone sit a little while that the percentage actually goes back up. For example, I kill netflix at 4% battery left. I set the phone down for a bit and when I pick it back up the battery is at 10%. I have seen this multiple times.
Just curious if anyone else has noticed this and anyone has an explanation for why this happens.
I believe it has to do with the battery meter displaying how much battery you have left based on what you are doing? So when you stopped being resource intensive it adjusted itself.
That's one explanation I have heard.. there is also one that has to do with the amount of current going to the battery.

I can't answer your question directly as there could be multiple reasons. (Battery capacity estimation is tricky business, and I don't know what algorithm they're using.)
But I can tell you that the common belief that one ought to discharge batteries before recharging them is not applicable to modern lithium batteries.
I was (to some extent) true for old-fashioned NiCd cells, but modern Li-ion cells shouldn't be excessively discharged. If you want to prolong battery life it's more important to keep the battery cool. (Lithium cells degrade much faster at elevated temperatures.)
(To contradict myself I have to add that the battery capacity calculation can be improved by discharging the battery completely from time to time - but again, this depends on the battery capacity calculation algorithm they're using.)
I understand the way current battery tech works. The discharge is not for the battery itself. Its for the Android OS. I have noticed that whenever I plug my phone in in the middle of the day, the next day my battery doesn't last as long. In fact the poor battery life will remain an issue for about a week until it levels itself back out. I have noticed this behavior on multiple phones by multiple manufacturers.
You end up going in a circle. You use heavy data one day and as a result you have to plug in in the middle of the day. The next day your battery doesn't last as long so you plug in again. Unless you allow your phone enough time to level back out then it will always appear that your battery life is aweful. Since i've been discharging my battery I am able to unplug my phone at 7:30 am, use it moderately all day with GPS, Bluetooth, 4G on/wifi off with a live wallpaper running. At 11:30pm when its time for bed I still have around 60-70% battery remaining. I find myself having to watch a few hours of netflix on 4g in order to drain the battery so I can plug it in.
I'm not sure if this behavior is a result of an issue with the battery stats file or what but I do know that when I flash a new ROM it appears my battery life is reset to how it was before I had shortened it by plugging in the middle of the day.
many of us have seen the percent rise slightly, its normal. when under heavy load watching videos or something and then you are finished, the voltage gets relaxed and pops up some. since this phone uses some type of voltage calculation to determine percent, it will jump up once in a rare while, typically right after you placed it under heavy load then went to idle.
it's normal..
this ebay bought magnetic chord i have lights blue led when its plugged in, and goes red when charging. however, now whenever its charging on my new z3c, it randomly fluctutates between red-blue red-blue although phone screen still shows its charging. any idea whats wrong? also, my phone is losing charge quicker since i charged with this chord (been only twice uptil now.) any suggestions? is it the phone or the chord only?
also, can generic chords actually spoil or harm the phones battery life? the first time i charged my z3c, it was with the inbox USB sony charger, and it lasted me a 10 hour night without a single % drop in battery on standby (though wifi and mobile data were both off, and i had no pending notifications in the am). Whereas, since charging with the generic magnetic chord, the battery's been dropping on standby at about 2% an hour. during intermittent screen checking, and dropped 3% last night (again wifi and data were off and no new notifications came in.)?? :-/ please help. thanks

i am having a similar experience using what i think is the same cord...i bought mine on ebay as well and it has the same blue/red led light...for me the color flickering seems to start at 90%+ when charging
i have also experienced worse battery drain when idle...i had a small suspicion that it was related to the charger but i also have different magnetic one and it seems to offer similar battery results...so its might just be magnetic charging altogether...i also read that some people believe it is the firmware update that caused the battery to drain faster...so im not exactly sure i can blame it on the charger
i have not done charge cycle from low battery to full with the oem charger in quite some time...maybe i will do that and see if the battery drains just as fast...maybe you could give it a try as well and see if it makes a difference (hopefully the magnetic charging hasn't already caused "permanent" damage)
yup, same flickering LED light here, mainly after about 90% charge. I've not noticed a difference in battery life betwen USB and mg or between different mag cables (I use two ebay mag cables and one Magnector x2). I do notice that one of the ebay cables charges a lot slower than the others, however.
Call me crazy, but I think that the flickering is normal. The flickering happens while the LED is trying to transition from Red to Blue, it should display a colour in between those two, but since there are only 2 LEDS (or 1 led with only two colors) aka two available colors, it will flicker because it's trying to do something that's impossible (trying to display a color beside red/blue). Mine does the same, but it doesn't bother me since it's supposed to do that. I don't have any battery issues.

I think you're not far off. I have the same cable probably, and it starts flickering in the mid-90%s. It probably has to do with the device reducing the charge drawn from the wall plug as it gets close to full battery.
Could you guys provide link to those chords?
Curious to know if somebody could share me regarding slow charging after 90%. Actually OP3 dash charging is damn awesome but after 90% or specially after 95% charging becomes too slow. Between I m in 3.5.5 community build. Any explanation or solution would be great.
not just oneplus but pretty much every manufacturer does this possibly to avoid battery damage. You are not supposed to charge batteries over 80% and below 40-50%, it gives your battery the longest life cycle however its something extremely hard to manage.
normal behaviour while charging.
charging above 80% is not really damaging the battery but its wearing them down little faster as it would when the level is kept between 20 to 80% (just what i heard from others)
i usually charge mine to ~ 90ish and unplug the phone
on average i get through a day with less than 60%
It's completely normal (and desired, like already pointed out). First few and last few percent are slower than mid-levels.
It still only takes a bit over an hour to charge from 0 to 100. And it's still the fastest charging device on market.
I'd say that's damn good enough ?

This is optimal for battery life, due to how lithium batteries work.
