For the past day the battery on the tablet seems to be stuck at 97%. If I plug the charger into it while in standby its says 'charged' but when I unlock it and check the battery percentage it says 97%.
I got the keyboard dock about 2 days ago and when the keyboard and tablet were paired the battery status would just be charging (lightning). Now it's just stuck on the same number. I had some notifications this morning for a firmware upgrade (tablet and keyboard) so I installed those but theirs been no change.
Any idea's ?
If it's any consolation mine's stuck at 96%. I'm guessing it needs to discharge fully and then be charged to calibrate.
yeah..agree this is probably just a calibration issue...it's ok..
Infinite Battery FTW.
Don't know if this is related. But I noticed that until my battery level goes down to 95%, it won't charge back to 100%, when it reads 96% and above even if its plugged in.
Considering how easy it is to boom a Lithium Ion battery I wouldn't be surprised if they decided to be conservative with it. 4% of 16 (potential) hours of use isn't too earth shattering. It does tweak the OCD though!
You would rather have your battery sit at 96% instead of it not being able to take a charge after 8 months..

Is anyone else experiencing a problem with battery charging on JF's ADP 1.5 release?
I've got this issue where I plug my phone in to the wall charger at night and it's on a cheap lamp timer so that it doesn't start to charge until 1.25 hours before I leave for work to prevent overcharging. Since I updated to 1.5 it seems that when the phone is On and starts the wall charge it treats it like a trickle charge as if it were connected via USB to a computer. Only after I turn the phone off does it rapidly charge like it should via the wall charger. Its a little annoying since the first day after the 1.5 update I didn't notice it and went in to work with a half charged battery. Now I know to look out for it and go turn the phone off when I wake up and by the time I'm ready to leave for work it's fully charged.

Wait, so does G1 have overcharge protection or doesn't it??
I didn't think it was necessary to protect from overcharging either.
I don't see this problem with my JF1.5 though - I plug it in at night and it charges full for when I wake up the next morning.

it should as that is very simple technology and is standard in many cheap devices now, so my guess is it would be in g1 or there would be a heck of alot more problems.........
on another note....ive noticed with JF 1.5 my battery icon gets a little stuck.....i thought it was an improvement of battery life until yesterday it stayed at 100% for like 5 hours but then dropped to 80% out of no where when i installed an app.......is anyone else having this issue??
I use battery graph from the market to see my battery charge over time. That's how I know that it "trickle" charges for me when connected to the wall charger until I turn the phone off.
BTW, when I turn the phone off then back on after waking up it does rapidly charge properly as well. Seems like it just needs a reboot for it to work right.
...and I'm sure that the G1 does have built-in overcharge protection, I just don't really trust it to do as good of a job as my cheap lamp timer does
Turn off your phone, remove you batter, put it back in, and turn your phone on. Everything should reset and be back to normal.
will try tonight.
no problem the power indicator or measurer is just more accurate in the 1.5 builds
i agree, used to fully charge in about an hour and a half, now its been takeing about 4 hours to hit 100% from about 1/2 charge...
ive noticed the same thing.
My phone charges fine with both my regular G1 battery and my Seidio Extended 2600mAh battery since my upgrade to JF ADP V1.50.
mine is on the trickle charge bug as well. phone stays cold throughout the 2 hours i've had it plugged in and its only at 68% charge. Brought it down to around 30% charge when I plugged it in to the wall.
My phone had the same problem when i updated to any of the 1.5 builds w/ radio. today, i drained the battery all the way until the phone died and took the battery out for about a min. Put it back in and started charging. My phone went back to charging normally up to 100% within ~2.5hrs. I've still yet to see how long this full battery will last until later today. Normally, i would get up to 2 days easy w/out charging on normal usage (a text or 5 min phone call here and there), 2G only, wifi disabled, bluetooth disabled. I'll let you guys know how it goes later.
This problem happens when the G1 is offline (airplane mode). When its online there is no problem with charging
mine has been acting weird since going to jf 1.5
last night i plugged it in at like 33% charged, and like 3 hours later it was at like 65%
i unplugged it, turned it off. turned it back on and when i plugged it in it was 100%.
before i charged it (when it was at 33%) i yanked the battery for a few seconds then put it back in then started to charge.
i'm going to do what JDMr2 did and let it die, yank the battery for a min then charge it and see how it goes.
It's always been charging more slowly on Cupcake than 1.x, BUT the battery lasts much, much longer.
well I took the battery out for a minute then put it back in. I left the phone on at night and plugged in the wall charger that's on my lamp timer before going to sleep. I woke up in the morning and looked at it in battery grapher and noticed that it rapidly charged from 30% until 60% then began to trickle charge the rest of the way up to 72% when I looked at the graph. I rebooted the phone, plugged it back in to the wall charger and it rapidly charged the rest of the way to 100%.
So, taking the battery out did not solve it. But interestingly I did discover that it rapidly charges until 60% then it switched into trickle charge mode. This is only after one observation however.
I've been having this problem as well but even prior to JF's version. I originally upgraded to the stock 1.5 from HTC (radio then firmware) and noticed the very slow charge times. I've tried pulling the battery and restarting but that hasnt changed anything. In the process now of completely draining the unit and then going to try again from there.
My G1 charges like normal.
JF1.5 ADP.
JF 1.5 nothing else fancy and I have noticed that charging has went from 45 mins or so to hours. Last night from amber it took 5 or so hours to go green. They definitely changed how the phone charges. Now my battery info says 73% and it has been moderately used for 7 hours. Looks like they went in a positive direction.
Is the first charge on the Nexus 5 still as important as a few years ago? Or is the N5's Li-Ion battery not as sensitive as Li-Po batteries?
I always used to plug in a new before booting them up, charge the battery completely and then unplug it. When the charge went down to about 5%, I plugged it back in. I always did that two or three times and then - while still trying to do it like that all the time - allowed myself to charge the device for a few minutes only when it was necessary instead of plugging it in and leaving it at home.
Well, on the N5, I didn't manage that - I actually forgot to monitor the battery level yesterday evening before going to bed. This morning, I noticed that the battery had reached 1% during the night and the N5 shut itself down.
Of course, I did now plug it back in, but I wonder if I could have damaged the battery by letting it run down to 1% on the first charging cycle? Or doesn't this matter at all and it will still reach its full capacity after a few charging cycles?
Thanks

I wouldn't worry about it, running a battery to empty is indeed bad but they don't allow you to run it to empty. It is programmed to show 1% and shut down before the battery itself is at 1% to prevent you from damaging it.
Use your phone, when charge is about 20% connect your charger and do not disconect until reaches the 100%.
This is what i have done with mine.
I have reached 2 days standby with about 3 hrs of screen on time.
What voltage ranges do you guys get for 100% and 1%?
I bought a new EB40 for a friend's phone and am getting some weird effects. I've previously done the EB40 in Atrix HD in my own phone and it's been fine, but I haven't actually let it run down below 50% yet.
Full Story:
At first the phone wouldn't turn on, but the LED would turn on when I plugged it into the charger. I left it on the charger for 10 minutes and then it would turn on to the battery charging screen, reporting 1% battery left.
I then made it boot into the OS. After a couple minutes charging, it jumped to 100%. I left it on for an hour, then disconnected it, and then it was slowly going down like normal. However, after it hit 85% or so, it just suddenly died.
Then I had to charge it and it was back to 1% and the same thing repeated.
I tried clearing battery stats (/data/system/batterystats.bin) but it seemed similar. Now I'm trying to run the battery till it dies, it's been at 1% for quite a while. Then I'll charge it back to 100%, but is it possible I got a dud?
We ran it down to 1% again, it died, and and it went back up to 100% again. I'm figuring once I get down to the real 1% and dies, when I turn it on it won't be at 100% like every other time. Then perhaps it will charge all the way up to the real 100%.
So far it's been like this voltage wise:
3.966V: 3%
...
3.725V: 1%
died
3.696V: 100%
...
3.663V: 1%
died
3.661V: 100%

i believe when these batterys are fully charged it should be around 4.300 so if the most your getting up to is 3.700 there is probably something wrong
I have noticed that when i plug my Z5 in to charge overnight, it will charge to full in just a few hours and then remain plugged in for the next ~6 hours until i unplug the phone 'fully charged" in the morning.
My theory is that the phone loses charge (maybe to protect the battery?) when left plugged in at full charge.
I will only get 3 hours SOT max if i leave my phone charging overnight. But if i unplug my Z5 as soon as it is fully charged i get 5 + hours SOT.
Also, often when i plug my phone into charge at 1 or 2 %, it sometimes actually causes my battery to die, before the phone boots again and starts to charge. Does anyone else notice this?
I am using the stock sony UCH 20 charger with came with my Z5.
What do you guys think?
That does sound peculiar. It should be noted that while it is normal for the phone to protect the battery by cycling between 90% and 100% when plugged in (battery gauge doesn't account for this, that's why it appears full all the time), it definitely shouldn't cause a 40% difference in SOT even if you happened to unplug when the battery is at 90 percent.
Yes, you're right. Once the battery is charged to 100%, the phone stops charging and will let the battery drop to around 92% and once it hits 92% it will start charging again to 100%. Even if you unplug the phone when it's showing 100% after charging at night, it might actually be charged to 93% for example. That's why very often people complain that the first 10% of the battery drops very quickly, while in fact it's just the battery meter catching up with the battery charge. This is done to protect the battery and ensure it retains charge after many cycles.
Regardless of that, the difference should not be that huge. For me it's usually extra 30 minutes SOT.
It seems the stock firmware has a load of random wakelocks but I have hope that a soon to come update will fix most of the issues, if you are rooted I suggest that you use greenify or amplify (reqires xposed)
So I've noticed that the phone doesn't charge above approximately 73% when fully turned off. I'm using the standard Google charger for the phone. It also charges normally when the phone is turned on. See screenshot...
My refurbished Pixel also does not show only around 65% charge after being plugged in for the whole night.
But then when I use it, it sort of freezes at a specific battery percentage, so it is on for example 30% for two hours, before it goes further down. See the attached picture.
So at least in my case, the phone is fully charged when turned off and plugged in, but somehow the percentage count of the phone does not recognize it. Maybe it's more or less the same in your case?
I too am having battery issues since updating to the latest October Android 10. I have bootloader unlocked and rooted with latest magisk Canary build.
I can charge to 100% but it then tends to stick at a certain% for a while and then the battery dies at 15-20%. I've tried battery calibration but it doesn't seem to help
I've had a dose of the same lately, had a couple of days where my charge has reached 42% for the entire day? Still charges fine but from a 100% charge I will lose at least 13% - 16% charge in a few hours on idle with nothing showing as draining heavy in battery manager. If I run it down to 18% or less and try and use the camera it will shutdown and if I can get it to reboot it's on 1%. I've come to the conclusion its the battery (could be wrong) purely as it's acting exactly the same way as my nexus 6p did when it's battery started to fail.
